Disclosure of Invention

Aiming at the defects in the prior art, the invention aims to provide a wire drawing device and a processing technology thereof, which have the advantage of facilitating wire drawing of relatively thin wires.

The above purpose of the invention is realized by the following technical scheme that the drawing of the fine silk thread is facilitated:

the utility model provides a wire drawing device, includes the wire drawing piece, the roof of wire drawing piece has been seted up and has been put the thing groove, the bilateral symmetry of wire drawing piece has been seted up the logical wire hole, the logical wire hole all with put the thing groove and communicate with each other, one of them side the downthehole lateral wall of logical wire is seted up and is put the thing annular, it is provided with the wire drawing piece to put the thing annular, including the wire drawing hole on the wire drawing piece, the cross-section in wire drawing hole is trapezoidal, the wire drawing piece is cylindric, the one end that wire drawing hole aperture is big is close to puts the thing groove, the axis in wire drawing hole and the axis in logical wire hole are in same straight line.

By adopting the technical scheme, an operator passes through the wire through hole from the guide roller far away from the direction of the wire drawing piece, the wire reaches the object placing groove through the wire through hole, passes through the lubricant in the object placing groove, passes through the wire through hole and finally passes out of the other wire through hole; the wire drawing piece is directly inserted into the article placing ring groove, and when the aperture of the wire drawing hole needs to be changed, the wire drawing piece only needs to be taken out from the article placing ring groove for changing; the drawing device with small volume and capable of replacing the drawing part at any time is convenient for drawing fine silk threads.

The invention is further configured to: the lateral wall of wire drawing piece is located logical silk hole department and all is provided with the guide bar, it is connected with the deflector roll to rotate on the guide bar, set up the silk groove that gathers that supplies the silk thread to pass along circumference on the deflector roll, it is located the axis in logical silk hole to gather the silk groove.

By adopting the technical scheme, the silk threads are guided by the silk gathering groove when entering and exiting the through hole, so that the abrasion of the silk threads caused by the friction between the silk threads and the inner side wall of the through hole is reduced.

The invention is further configured to: the guide rod comprises two first cross rods fixed on two sides of the wire drawing block and a second cross rod located between the two cross rods, the second cross rod is rotatably connected to the wire drawing block, adjusting holes are formed in the first cross rods, adjusting bolts are connected to the inner equal threads of the adjusting holes, and end walls of the adjusting bolts can be abutted to outer side walls of the wire drawing block.

Through adopting above-mentioned technical scheme, according to the needs of process to silk thread height around the actual conditions, unscrew adjusting bolt rotates first horizontal pole and makes pipe cooperation silk thread for the silk thread reduces with the downthehole lateral wall of harness cord friction.

The invention is further configured to: and an auxiliary rod is arranged at one end of the adjusting bolt far away from the direction of the wire drawing block.

Through adopting above-mentioned technical scheme, when the height of deflector roll is adjusted to needs, need adjusting bolt, the twisting of accessible auxiliary rod auxiliary control bolt moves, and the operating personnel of being convenient for twists adjusting bolt when not having appurtenance.

The invention is further configured to: and a protective pad is arranged at one end of the adjusting bolt close to the direction of the wire drawing block.

Through adopting above-mentioned technical scheme, when first horizontal pole need carry out the locking, adjusting bolt need offset tightly with the lateral wall of wire drawing piece, and adjusting bolt causes the extrusion to the outside of wire drawing piece for a long time this moment and causes the sunken of wire drawing piece lateral wall easily, so avoid adjusting bolt and wire drawing piece's direct contact through the protection pad to alleviate the sunken condition of wire drawing piece lateral wall.

The invention is further configured to: be close to perpendicular threaded connection has two extension rods on two first horizontal poles of wire drawing piece direction, two the tip that the extension rod is close to each other is provided with the clearance board, the one end that the extension rod direction was kept away from to the clearance board is provided with the clearance cotton, two the clearance board is close to and makes two clearance cotton between support tightly, the tip that the clearance board was kept away from to the extension rod is provided with and is used for extension rod pivoted dwang.

Through adopting above-mentioned technical scheme for the silk thread is located between two clearance boards, rotates the extension rod, makes the clearance cotton support each other tightly, is passed in the middle of two clearance cottons from tensile silk thread, strikes off unnecessary emollient, reduces the influence of emollient to follow-up work.

The invention is further configured to: the cleaning plate and the extension rod are in threaded connection.

Through adopting above-mentioned technical scheme, when the clearance cotton need be changed after being rubbed for a long time, the rotatable dwang of operating personnel for the extension rod is kept away from each other, and the clearance board of twisting off this moment is changed, and makes the silk thread be located between two clearance boards, screws up new clearance board and rotates the extension rod after on the extension rod, makes two clearance cottons paste tightly again.

The invention is further configured to: one side that the wire drawing piece is close to the extension rod direction is provided with collects the cell body, it is located the clearance board under to collect the cell body.

Through adopting above-mentioned technical scheme, the silk thread is by passing the back between the clearance board, and the emollient that is scraped off by the clearance cotton drops to the collecting vat to ground in, and operating personnel regularly retrieves the reuse to the emollient in the collecting vat, has improved the utilization ratio of material.

A processing technology for a wire drawing device comprises the following steps:

s1: end portion pretreatment, namely, firstly, pretreating and thinning the end portion of the wire coil;

s2: feeding, namely passing the end part of the pretreated wire coil through a through wire hole from a guide roller far away from the direction of a wire drawing piece;

the silk threads reach the object placing groove through the silk drawing holes, pass through the lubricant in the object placing groove, pass through the silk drawing holes and finally pass out of the other silk drawing hole;

the silk thread penetrating through the through-thread hole is cleaned by the cleaning cotton between the two cleaning plates to remove the redundant lubricant on the surface;

s3: adjusting, namely loosening the adjusting bolt through the auxiliary rod, and rotating the first cross rod according to the actual position of the silk thread so that the silk thread smoothly passes through the silk gathering groove of the guide roller;

s4: drawing, starting a winder to draw and wind the silk thread;

s5: and (4) recovering, wherein after the silk threads pass through the cleaning plates, redundant lubricant drops in the collecting tank body, and the lubricant in the collecting tank body is recovered and reused at regular time.
