A rolling apparatus, with reference to fig. 1, comprising: the mixing device comprises an upper mixing device 100 and a lower mixing device 110, wherein the upper mixing device 100 is positioned above the lower mixing device 110, and a gap is formed between the upper mixing device 100 and the lower mixing device 110; a propelling platform 120, and a driving roller (not shown) on the surface of the propelling platform 120.

In the process of using the rolling device, a forklift is usually used to transport the target 130 to the transmission roller on the surface of the pushing platform 120, and then the target 130 is pushed between the upper binding mixer 100 and the lower binding mixer 110 by means of manual pushing of the target 130; rolling the target 130 between the upper binding mixer 100 and the lower binding mixer 110 by the rotation of the upper binding mixer 100 and the lower binding mixer 110; the target 130 is formed into a target material strip through multi-pass rolling.

However, the manual pushing of the target 130 is labor-intensive, which reduces the transfer efficiency, and the safety of the transfer is reduced if the target 130 is improperly protected and falls down.

On this basis, the present invention provides a rolling apparatus comprising: the automatic carrying platform is positioned on the side part of the rolling mill main body, faces the gap and is used for conveying the target materials to the space between the upper binding and the lower binding; the automatic carrying platform comprises: the transmission rolling rods are located on the base platform and are arranged along the direction parallel to the surface of the base platform, the central shafts of the transmission rolling rods are all parallel to the rotary central shaft mixed with the base platform, the bearings are fixed on the surface of the base platform and are sleeved with the two ends of each transmission rolling rod respectively, and the motor set is used for driving each transmission rolling rod to rotate around the central shaft of the transmission rolling rod. The rolling device improves the efficiency and the safety of conveying the target material.

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.

The present embodiment provides a rolling apparatus for rolling a target material, which is characterized by, with reference to fig. 2, including:

a mill body 200, said mill body 200 comprising: the mixing device comprises an upper mixing drum 210 and a lower mixing drum 220, wherein the rotating central axis of the upper mixing drum 210 is parallel to the rotating central axis of the lower mixing drum 220, the upper mixing drum 210 is positioned above the lower mixing drum 220, and a gap is formed between the upper mixing drum 210 and the lower mixing drum 220;

an automatic carrying platform 300, wherein the automatic carrying platform 300 is located at the side of the rolling mill main body 200, the automatic carrying platform 300 faces the gap, and the automatic carrying platform 300 is used for conveying the target material between the upper and lower binding mixtures 210 and 220;

the automatic carrying platform 300 includes: the roller table comprises a base table 310, a motor set (not shown), a plurality of transmission rollers 320 and a plurality of bearings 330, wherein the transmission rollers 320 are positioned on the base table 310 and are arranged in a direction parallel to the surface of the base table 310, the central axes of the transmission rollers 320 are all parallel to the rotating central axis of the lower rolling mixer 220, the bearings 330 are fixed on the surface of the base table 310, the bearings 330 are respectively sleeved with the two ends of each transmission roller 320, and the motor set is used for driving each transmission roller 320 to rotate around the central axis of the transmission roller 320.

The bearing 330 is respectively sleeved with two ends of each transmission roller 320, which means that: one end of the driving roller 320 is positioned in the inner race of one bearing 330, and the other end of the driving roller 320 is positioned in the inner race of the other bearing 330.

The central axis of the driving roller 320 is parallel to the extending direction of the driving roller 320.

The motor group comprises a plurality of motors, the number of the motors is the same as that of the transmission rollers 320, and one motor is used for driving one transmission roller 320 to rotate around the central shaft of the transmission roller 320.

In one embodiment, the top of each drive roller 320 is the same height as the top of the downmixed 220.

In another embodiment, the top ends of the transmission rollers are the same in height; and the distance from the top end of the transmission rolling rod to the top end of the downmixed rod in the vertical direction is more than or equal to zero and less than or equal to 200 mm. If the distance from the top end of the drive roller to the top end of the lower binding mixer in the vertical direction is greater than 200 mm, the target is less aligned with the gap when the target is conveyed by the drive roller to approach the upper binding mixer 210 and the lower binding mixer 220, which makes it difficult to convey the target further between the upper binding mixer 210 and the lower binding mixer 220.

In this embodiment, the motor set drives the plurality of transmission rollers 320 to rotate around the central axis of the transmission rollers 320, so as to transmit the target on the transmission rollers 320 to the space between the upper binding mixer 210 and the lower binding mixer 220, thereby avoiding pushing the target to the gap by manpower, and improving the efficiency of transmitting the target. Secondly, the target is stably transported to the gap between the upper binding mixer 210 and the lower binding mixer 220 by controlling the transmission speed of the transmission roller 320 through a motor set, so that the safety of target transmission is improved.

In this embodiment, the automatic carrying platforms 300 are respectively located at both sides of the rolling mill body 200, and a direction from the center of the automatic carrying platform 300 at one side of the rolling mill body 200 to the center of the automatic carrying platform 300 at the other side of the rolling mill body 200 is perpendicular to the rotation central axis of the lower rolling mixer 220. For convenience of explanation, the automatic carrying platforms 300 on both sides of the rolling mill body 200 are divided into: an automatic carrying platform 300 on a first side of the rolling mill body 200 and an automatic carrying platform 300 on a second side of the rolling mill body 200.

The automatic carrying platforms 300 are respectively located at both sides of the rolling mill body 200, which is advantageous in that: after the target material is conveyed to the gap by the automatic carrying platform 300 on the first side of the rolling mill main body 200 and rolled, the target material is carried by the automatic carrying platform 300 on the second side of the rolling mill main body 200, and then the target material is conveyed to the gap by the automatic carrying platform 300 on the second side of the rolling mill main body 200 and rolled, so that the target material does not need to be manually moved in the rolling process of two adjacent passes.

In other embodiments, the automated carrying platform is located on only one side of the mill body.

In this embodiment, referring to fig. 3, a slit is formed between the adjacent driving rollers 320; the base platform 310 has a plurality of openings 311 penetrating through the base platform 310, and the openings 311 are respectively located at the bottom of the slits.

In this embodiment, the rolling apparatus further includes: a top supporting device 340 (refer to fig. 2 and 3 in combination) located at the bottom of the base platform 310, wherein the top supporting device 340 comprises a supporting base 341 and a plurality of discrete top plate units 342, the supporting base 341 has a first supporting surface facing the base platform 310, the top plate units 342 are fixed on the first supporting surface, and the top plate units 342 are perpendicular to the first supporting surface; the top sheet unit 342 is adapted to pass through the opening 311 and the slit and reciprocate in a direction perpendicular to the first supporting surface.

The supporting base 341 further has a second supporting surface opposite to and parallel to the first supporting surface, and the second supporting surface faces away from the base 310.

The rolling device further comprises: a power device (not shown) positioned at the bottom of the top bracing device 340; a transmission rod (not shown) located between the power device and the top bracing device 340, wherein one end of the transmission rod is connected with the power device, and the other end of the transmission rod is fixedly connected with the second supporting surface; the power device is used for driving the transmission rod to reciprocate along the direction vertical to the first supporting surface. The power device includes a motor.

In this embodiment, the distance between the adjacent driving rollers 320 is 100 mm to 200 mm, the diameter of the driving rollers 320 is 150 mm to 200 mm, and the width of the top plate unit 342 is 50mm to 70 mm.

If the distance between the adjacent drive rollers 320 is less than 100 mm, which results in a small space between the adjacent drive rollers 320, the top sheet unit 342 passing through the adjacent drive rollers 320 is easily contacted with the drive rollers 320, and the interaction force between the top sheet unit 342 and the drive rollers 320 causes the top sheet unit 342 to break; if the distance between the adjacent driving rollers 320 is greater than 200 mm, the density of the driving rollers 320 is small, the contact area between the driving rollers 320 and the target material is small, the acting force applied to the target material is limited, and the driving force of the driving rollers 320 is small.

If the diameter of the driving roller 320 is smaller than 150 mm, the linear velocity of the driving roller 320 is smaller, and the conveying speed of the driving roller 320 to the target is smaller; if the diameter of the driving rollers 320 is greater than 200 mm, the number of the driving rollers 320 contacting the target is small, and the contact area between the driving rollers 320 and the target is also reduced, so that the acting force applied to the target is limited, and the driving force of the driving rollers 320 is small.

The width of the top sheet unit 342 is 50mm to 70 mm in the sense that: the top sheet unit 342 can easily pass through the opening 311 and the slit, and meanwhile, the contact area between the single top sheet unit and the target is not too small, and the pressure between the top sheet unit 342 and the target is not too large, so that the surface of the target in contact with the top sheet unit 342 is not easily damaged.

The width of the opening 311 is greater than or equal to the width of the slit.

The width of the opening 311 and the width of the slit both refer to: a dimension in a direction parallel to the surface of the base 310 and perpendicular to the rotation center axis of the driving roller 320.

The width of the seam refers to: the minimum distance between the edges of adjacent drive rollers 320.

The rolling mill main body 200 further includes: a hydraulic device (not shown) for adjusting the size of the gap between the upmix 210 and the downmix 220.

Accordingly, the present embodiment also provides a rolling method, referring to fig. 4, including:

providing the rolling device described above (see fig. 2);

providing a target 400 (see fig. 5);

placing the target 400 on a transmission roller 320 of an automatic carrying platform 300;

after the target 400 is placed on the transmission rollers 320 of the automatic carrying platform 300, the motor set drives the transmission rollers 320 to rotate around the central axis of the transmission rollers 320;

transferring the target 400 between the upper and lower bundled mixtures 210 and 220 by rotation of the drive rollers 320;

the target 400 between the upper and lower bundles of mixes 210 and 220 is rolled by the rotation of the upper and lower bundles of mixes 210 and 220.

The rolling method further comprises: before the target 400 is placed on the roller 320 of the automatic carrying platform 300, the top supporting device 340 is driven to ascend (refer to fig. 6), so that the top sheet unit 342 passes through the opening 311 and the slit, and the distance from the top of the top sheet unit 342 to the surface of the base table 310 is greater than the distance from the top of the roller 320 to the surface of the base table 310; after the top plate units 342 are passed through the opening 311 and the slit, the target 400 is placed on the top end surfaces of the top plate units 342 (refer to fig. 7); after the target 400 is placed on the top end surfaces of the top plate units 342, the top support device 340 is driven to descend until the top plate units 342 are separated from the target 400 and the target 400 is in contact with the driving roller 320 (refer to fig. 8).

The top supporting device 340 is driven to ascend, the top sheet units 342 pass through the openings 311 and the slits, then the target materials are placed on the top end surfaces of the top sheet units 342, and then the top supporting device 340 is driven to descend until the top sheet units 342 are separated from the target materials and the target materials are in contact with the transmission roller 320, so that the target materials are placed on the transmission roller 320. This has the advantages that: the target material can be efficiently and accurately placed on the transmission roller, meanwhile, the impact or loss caused by improper manual target material placement on the transmission roller can be avoided, and the effect of protecting the transmission roller is achieved.

The size of the gap is adjusted before the target 400 is transferred between the upper and lower bundled mixtures 210, 220 by the rotation of the drive rollers 320.

The rolling method further comprises: the steps of placing the target 400 on the transmission roller 320 of the automatic carrying platform 300 to roll the target 400 between the upper rolling mixture 210 and the lower rolling mixture 220 are repeated, so that the target 400 forms a target material belt.

For example, if the target 400 has a thickness of 50mm and the target strip is desired to have a thickness of 8mm by rolling, then the total rolling amount for the target 400 would need to be 42 mm.

The distance between the upper and lower mixes 210 and 220 in each pass is different for several passes.

When the target 400 with the thickness of 50mm is rolled into the target material strip with the thickness of 8mm in 6 passes, the rolling amount of the 6 passes is gradually reduced, for example, the rolling amount is 12mm, 10mm, 8mm, 6mm, 4mm and 2mm in sequence.

The rolling quantity of each pass is decreased gradually, and the advantages comprise: the microstructure, such as crystal grains and crystal orientations, inside the target material belt is better shaped.

In other embodiments, the rolling quantity of each pass is the same for several passes of the rolling process.

In one embodiment, the transfer rate of the target material by the drive rollers is a first rate during the transfer of the target material between the upwrap and the downwrap mixing by rotation of the drive rollers; the linear velocities of the upper and lower mixing surfaces are both a second velocity; the first rate is 95% to 105%, such as 100%, of the second rate.

If the first rate is larger than 105% of the second rate, the target material causes larger impact damage to the upper binding and the lower binding; if the first speed is less than 95% of the second speed, the transmission efficiency of the target material is low, and the rolling productivity is affected.

In the rolling method provided by the embodiment, the motor group drives the plurality of transmission rollers to rotate around the central axis of the transmission rollers, so that the target on the transmission rollers is transmitted to the upper binding and mixed with the lower binding and mixed, the target is prevented from being pushed to a gap by manpower, and the target transmission efficiency is improved. Secondly, the target is stably transported to the gap between the upper binding and the lower binding by controlling the transmission speed of the transmission roller through the motor set, so that the safety of target transmission is improved.

The rolling method further comprises: heating the target material before placing the target material on a transmission roller of an automatic carrying platform.

In one embodiment, the target is heated to 190-210 ℃ and then placed on a transmission roller of an automatic carrying platform.

Before the target is placed on a transmission rolling rod of an automatic carrying platform, the target is heated, namely the target is rolled by hot rolling. The target material is stably conveyed to the space between the upper binding and the lower binding and mixing by controlling the conveying speed of the transmission roller, so that the conveying time for conveying the target material to the space between the upper binding and the lower binding and mixing can be accurately controlled, and the large time difference caused by manually conveying the target material is avoided, so that the cooling time of the target material exposed in the air can be effectively controlled, the rolling process is highly stable, and the rolling effect of the target material is effectively controlled.

In other embodiments, the target is not heated before being placed on the driving roller of the automatic carrying platform, i.e. the target is rolled by cold rolling.
