Background

The section bar is a strip material which is formed by plastic processing and has a certain section shape and size, wherein the pipe also belongs to a section bar with a special shape. At present, profiles are widely used in the field of industrial manufacturing, for reproducible equipment or products, the length of the profile is a fixed value established according to design drawings, and in order to improve the production efficiency of the equipment or products, it is the conventional practice to cut a long profile into a plurality of equal-length profiles in sections. The selection of the length of the section bar can be determined according to a certain multiple of the length of the required section bar material and a reasonable cutting allowance, or the section bar with any length can be directly used. However, after the profile is cut, a long section of profile tailing always remains, and if the profile tailing is not cut for the second time, the profile is wasted, but if the profile tailing is cut for the second time, the cutting efficiency of the profile is reduced. Therefore, a cutting method capable of fully utilizing the section bar tailing is needed.

In some embodiments of the present invention, in order to be able to detect the length of the profile in order to use different segmental cutting methods for the profile according to its different length, the machine frame 100 is provided with an inductive sensor (not shown in the drawings), which may be a correlation photoelectric sensor or a proximity switch. When the induction sensor detects the profile, the length of the profile is still out of the specified value, and the profile is defined as a profile long material 610; when the induction sensor does not detect the profile, the length of the profile is within a specified value, the profile is defined as the profile tail 620, the distance between the induction sensor and the cutting part is the maximum length of the profile tail 620, and the actual length of the profile tail 620 can be calculated according to the movement parameters of the first front-back moving mechanism 210.

s10, detecting the length of the profile by the induction sensor, and if the length of the profile is greater than y₀If so, defining the profile as a profile long material 610, and jumping to S610; if the length of the profile is less than or equal to y₀If so, define the profile as a profile tail620, and jumping to S100;

s610, as shown in fig. 2, after the cutting device 400 performs the segmental cutting on the long profile 610, the clamping device 300 and the discharging device 500 simultaneously release the long profile 610, the feeding device 200 clamps the long profile 610 and drives the long profile 610 to move a cutting distance of the long profile 630 in a positive feeding direction under the driving of the first forward-backward moving mechanism 210, so that the long profile 610 can pass through the cutting part forward;

s620, simultaneously clamping the long section material 610 by the clamping device 300 and the discharging device 500, and cutting the long section material 610 by the cutting device 400 in a segmented manner to obtain a sub-section material 630;

s630, repeating S610 and S620 circularly until the distance between the feeding device 200 and the clamping device 300 is smaller than the cutting distance of one section material;

s640, the feeding device 200 loosens the long section material 610 and moves in the opposite feeding direction by the driving of the first front-back moving mechanism 210 by a cutting distance not less than one section material;

s650, repeating S610, S620, S630 and S640 in a circulating way until the length of the section bar is less than or equal to y₀All the sectional materials 630 are located on the third mounting plate;

s100, as shown in fig. 3, after the cutting device 400 performs the segmented cutting on the long profile 610, the feeding device 200 clamps the profile tail 620, and drives the profile tail 620 to move a distance a in the positive feeding direction under the driving of the first forward-backward moving mechanism 210, so that the profile tail 620 can pass through the cutting portion forward;

s200, as shown in fig. 4, the feeding device 200 loosens the profile tailings 620, the discharging device 500 clamps the profile tailings 620, and drives the profile tailings 620 to move by a distance of z-a along the positive feeding direction under the driving of the second forward-backward moving mechanism 510, at this time, the workpiece section and the lower tailing section of the profile tailings 620 are respectively located at the front side and the rear side of the cutting part;

s300, simultaneously clamping the section bar tailing 620 by the clamping device 300 and the discharging device 500, and cutting the section bar tailing 620 by the cutting device 400 to obtain a leftover 640, wherein the length of the leftover 640 is smaller than that of the section bar tailing 630;

s400, the clamping device 300 releases the section tailings 620, the discharging device 500 clamps and drives the section tailings 620 to move for a cutting distance of a section material 630 in the opposite direction of feeding, then the clamping device 300 and the discharging device 500 clamp the section material tailings 620 simultaneously, and the cutting device 400 cuts the section material tailings 620 in sections to obtain a section material 630;

s500, repeating S400 continuously until k pieces of profile material 630 are obtained, where the trim 640 and the k pieces of profile material 630 are located on the second mounting plate.

It should be noted that, since the cutting portion has a certain thickness, the influence of the thickness of the cutting portion needs to be considered when cutting, and for this reason, the cutting distance of the section bar material 630 is equal to the sum of the length of the section bar material 630 and the thickness of the cutting portion.

According to the above-described profile slitting method, when the profile is the long profile 610, the profile slitting method (i.e., S610 to S650) continues to use the conventional slitting method in which the clip device 300 has a certain length, which hinders the forward movement of the feeding device 200, so that the tail profile 620 cannot be further slit. For this reason, the present invention provides an improvement to the existing profile slitting method, so as to provide a slitting method (i.e., S100 to S500) capable of fully utilizing the profile tails 620, and the new profile slitting method mainly utilizes the discharging device 500 to reversely feed the profile tails 620 for a plurality of times to slit as many profile sub-materials 630 as possible and a scrap 640 shorter than the length of the profile sub-material, so that the profile tails 620 can be fully utilized, and the waste of the profile is avoided. In addition, since k is a positive integer greater than 1, a sufficient feeding distance is reserved for the feeding device 200, so that the feeding device has no special requirements on the structure of the feeding device 200 and the structure of the clamping device 300, and the universality is high.

It is understood that, in the process of S200, in order to enable the discharging device 500 to clamp the profile tailings 620, the value of a is greater than or equal to the minimum clamping length of the discharging device 500.

In some embodiments of the present invention, when the lengths of all the sectional materials 630 are not less than the minimum clamping length of the discharging device 500, all the sectional materials 630 have the same length, and the length of each sectional material 630 is x, because the discharging device 500 does not affect the cutting of the sectional material tail 620 at this time₁. Although the invention is not limited to the specific value of a, in order to facilitate the parameterization processing, in the embodiment, a is x₁. For example, assuming that the minimum clamping length of the discharging device 500 is 20mm, the actual length of the profile tailings 620 is 145mm, the thickness of the cutting part is 3.2mm, the length of the profile sub-material 630 is 30mm, since the length of the profile sub-material 630 is greater than the minimum clamping length of the discharging device 500, the value of a may be selected to be 30mm, and since 145/(30+3.2) ═ 4.36, the value of k is 4, when the length of the workpiece segment is (30+3.2) × 3+30 ═ 129.6mm, and the length of the lower heel segment is 15.4 mm.

In other embodiments of the present invention, when the length of the section bar 630 is smaller than the minimum clamping length of the discharging device 500, since the discharging device 500 interferes with the cutting of the end of the section bar tail 620, in order to eliminate the interference, the length of one section bar 630 is a, and the lengths of all the other section bars 630 are x₂，x₂Is less than the minimum gripping length of the outfeed device 500. In the embodiment, the section bar tailing 620 is cut into k-1 sections with the length x₂Since the maximum clamping length of the discharging device 500 is greater than x after the section bar 630 is processed₂Due to the factThe profile tail 620 cannot be further cut, and the profile tail 620 can be directly used as the last profile material 630, so that two profile materials 630 with different lengths can be obtained. For example, assuming that the minimum clamping length of the discharging device 500 is 20mm, the actual length of the profile tailings 620 is 145mm, the thickness of the cutting part is 3.2mm, the value of a is 30mm, the length of the profile sub-material 630 is 15mm, and the length of the profile sub-material 630 is smaller than the minimum clamping length of the discharging device 500, the length of one of the profile sub-materials 630 is 30mm, and the lengths of all the remaining profile sub-materials 630 are 15mm, since the length of the profile sub-material 630 is smaller than the minimum clamping length of the discharging device 500, the value of k is 6 in view of (145-30)/(15+3.2) being 6.31, and the length of the workpiece segment is (15+3.2) × 6+30 being 139.2mm, and the length of the blanking segment is 5.8 mm.

In some embodiments of the present invention, the size of the second and third mounting plates can be increased to accommodate all of the cut section bars 630 in a single section cutting process.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the gist of the present invention.
