Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of steel cord, in particular to a gripper for wire drawing Background Art
[0002] There are two manufacturing processes for steel wires. One is to roll them using rolls with arc grooves, and the other is to draw them thinner through a wire drawing die. When wire drawing, first use a tip rolling machine to roll the head of the steel wire thinner, and then pass it through the wire drawing die. It is wound around a wire drawing drum, and the wire drawing drum is driven by a motor. The drum pulls the steel wire from one end of the die to the other end. However, at the beginning, the steel wire only has a very short section that is slightly thinned by the tip rolling machine and passes through the die, but it cannot be wound around the wire drawing drum. At this time, a special tool is needed to clamp one end of the steel wire and wind the other end around the wire drawing drum, so that the wire drawing drum can pull the steel wire out of the die
[0003] The traditional drawing tool is an inclined iron and a clamp body. There is an insertion hole in the clamp body. One side of the insertion hole is an inclined surface, and the other side is a serrated surface. The inner hole angle is the same as that of the inclined iron, but slightly larger in size. When in use, the steel wire is placed in the gap between the clamp body and the inclined iron, and a small hammer or a tool that can strike is used to strike the large end of the inclined iron to clamp the steel wire
[0004] However, this clamping device has several disadvantages. When wire drawing, a foot switch is generally used to operate the machine by point motion. When the foot switch is released, the motor stops, and sometimes it will rotate back a little under the wire tension, and the inclined iron sometimes loosens, resulting in the wire falling off. Another disadvantage is that the serrated surface is prone to wear during use, resulting in insufficient clamping force and causing the steel wire to come out. Moreover, the entire clamp body needs to be replaced, which is relatively wasteful of materials and the processing is also relatively complex Summary of the Invention
[0005] The utility model provides a gripper for wire drawing, which can use clamping jaws for clamping, ensure the stability of the clamping jaws during clamping through an elastic member, and at the same time, facilitate the replacement of the serrated groove when it is worn through a detachable clamping block
[0006] To achieve the above object, the utility model provides the following technical solutions
[0007] A gripper for wire drawing, comprising a clamp body, wherein a groove is provided on the side of the clamp body, and an opening is provided towards one side of the groove
[0008] Clamping jaws, two clamping jaws are provided and symmetrically arranged in the groove
[0009] A top block is slidably disposed in the groove. The clamping jaws are hinged to both ends of the top block. When the top block pulls the clamping jaws towards the inner side of the groove, the opposite surfaces of the two clamping jaws are separated. When the top block pushes the clamping jaws towards the opening, the opposite surfaces of the two clamping jaws gradually approach and clamp together.
[0010] Wherein, clamping blocks are detachably mounted on the opposite surfaces of the two clamping jaws, and serrated grooves are provided on the outer side surfaces of the clamping blocks.
[0011] Further, symmetric inclined grooves are provided on both sides in the groove. The center line of the inclined groove is the same straight line as the center line of the opening, and the clamping jaws are slidably disposed in the inclined grooves.
[0012] Further, a compression spring is provided between the back of the top block and the groove.
[0013] Further, a connecting buckle is further included. Both ends of the connecting buckle are respectively hinged and fixed to the clamping jaws and the top block.
[0014] Further, a cover plate is further included. The cover plate covers the upper part of the groove. A sliding groove is provided on the cover plate. The length direction of the sliding groove is arranged along the opening and the bottom of the groove. A fixing block is fixedly connected to the top block, and the fixing block passes through the sliding groove.
[0015] Further, mounting grooves matching the size of the clamping blocks are provided on the clamping jaws, and the clamping jaws are fixedly connected to the clamping blocks by screws passing through the through holes provided thereon in a threaded manner.
[0016] Further, a hinge hole is provided on one side of the clamp body for connecting a chain.
[0017] The utility model has the following beneficial effects:
[0018] First, in this structure, two clamping jaws are disposed in a groove. The opening and closing of the clamping jaws are driven by the push of the top block. Detachable clamping blocks with serrated grooves are provided on the opposite surfaces of the clamping jaws, which is convenient for replacement when the serrated grooves are worn, and avoids wire slipping.
[0019] Second, in order to ensure the stability of the opening and closing of the clamping jaws, inclined grooves are provided in the groove, and the clamping jaws are slidably disposed in the inclined grooves. In this way, when the clamping jaws extend out of the opening at the end of the inclined grooves, they can close and clamp the wire, and when they are in the groove, the clamping jaws can be opened by the middle protruding part of the two inclined grooves.
[0020] Third, in order to avoid the problem of loosening of the clamping jaws during use, a compression spring is provided between the back of the top block and the groove.
[0021] Fourth, by providing a connecting buckle, the rotational connection is increased, making it easier for the clamping jaws to fit and slide along the inclined grooves.
[0022] 5. By setting a cover plate and arranging a chute on the cover plate, and installing a fixing block on the top block and passing the fixing block through the chute, when in use, it is convenient for the staff to push the top block to move, so that the clamping jaws are separated.
[0023] 6. Arrange an installation groove on the clamping jaw that matches the clamping block, and fix the clamping block on the clamping jaw with screws. Only need to process smaller clamping blocks with high hardness, which is convenient for processing and replacement. BRIEF DESCRIPTION OF THE DRAWINGS

Symmetric inclined grooves 103 are provided on both sides in the groove 101. The center line of the inclined groove 103 and the center line of the opening 102 are on the same straight line. The clamping jaw 20 is slidably arranged in the inclined groove 103. A compression spring 301 is arranged between the back of the top block 30 and the groove 101.
[0035] Specifically, the fixture body 10 is made of medium carbon alloy steel. A groove 101 is machined on one side. An opening 102 is provided at one end of the groove. Symmetric inclined grooves 103 are machined on both sides in the groove 101. An arc-shaped protrusion is arranged between the two inclined grooves 103 and is used to limit the positions of the two clamping jaws 20 through the opening 102 and the inclined grooves 103. A flat-bottom blind hole is respectively arranged on the arc-shaped surfaces of the top block 30 and the bottom of the groove 101 to limit the position of the compression spring 301. The compression spring 301 is made of 65Mn spring steel wire.
[0036] Furthermore, in order to make the clamping jaw 20 move along the inclined groove 102 more easily, a connecting buckle 40 is also provided. Both ends of the connecting buckle 40 are respectively hinged and fixed to the clamping jaw 20 and the top block 30.
