Description

Technical Field

[0001] This utility model relates to the technical field of screw processing equipment, and in particular to a feeding and traction device for screw processing. Background Technology

[0002] The screw cutting process mainly consists of a feeding mechanism, a straightening and traction unit, a fixed-length cutting and material collection assembly. After the metal wire is straightened by rollers, it is fed by a servo motor, positioned by a sensor or mechanical stop, and then precisely cut to the set length by a pneumatic / hydraulic shearing mechanism. It is suitable for processing stainless steel, carbon steel and other wire materials.

[0003] The straightening traction unit typically uses rollers for straightening. However, rollers are usually adjusted by adjusting a single roller with a single screw, and the distance between two adjacent rollers is adjusted. This is not only inefficient, requiring multiple screws to be adjusted one by one to achieve the desired straightening effect, but also has poor synchronization. The individual operation can easily lead to uneven force on the roller group, affecting the consistency of the straightness of the metal wire, which is quite inconvenient. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] This utility model provides, for example Figure 1-7 The screw processing feeding and traction device shown includes a worktable 1, a traction mechanism 3 and a straightening mechanism 4. A fixed frame 2 is fixedly connected to one side of the worktable 1. The traction mechanism 3 is set on the worktable 1 for traction of metal wire.

The top of the worktable 1 has a groove. The first cylinder 31 is fixedly installed at the bottom of the inner wall of the groove. The end of the slide rod 32 is fixedly connected to the inner wall of the groove. The traction plate 33 is slidably inserted and connected to the slide rod 32. The output end of the first cylinder 31 is connected to the traction plate 33 through a transmission. The first cylinder 31 can drive the traction plate 33 to move back and forth in the horizontal direction under the limit of the slide rod 32.

[0022] Furthermore, the traction mechanism 3 also includes a fixed clamping block 34, a movable clamping block 35, and a second cylinder 36. A traction groove is provided on the traction plate 33. The fixed clamping block 34 is fixedly connected to the inside of the traction groove. The movable clamping block 35 is slidably inserted into the inner cavity of the traction groove. The second cylinder 36 is fixedly connected to the outer wall of the traction plate 33. The output end of the second cylinder 36 is connected to the movable clamping block 35 for transmission. The second cylinder 36 can drive the movable clamping block 35 and the fixed clamping block 34 to perform clamping operations on metal wires of different diameters. With the push of the first cylinder 31, the traction operation of the metal wire can be completed.

[0023] Furthermore, the top and bottom ends of the movable clamping block 35 are fixedly connected to sliders 37, and the top and bottom ends of the inner wall of the traction groove are provided with sliding grooves. The sliders 37 are slidably inserted into the inner cavity of the sliding grooves. The sliders 37 play a limiting role for the movable clamping block 35, so that the movable clamping block 35 can only move horizontally inside the traction groove.

[0024] Specifically, the straightening mechanism 4 includes straightening wheels 41, rotating rods 42, adjusting components 43, and positioning components 44. The straightening wheels 41 are equidistantly arranged inside the fixed frame 2. The straightening wheels 41 are rotatably mounted outside the rotating rods 42 via bearings. The top and bottom of the inner wall of the fixed frame 2 are provided with transverse grooves. The end of the rotating rods 42 is slidably inserted into the inner cavity of the transverse grooves. The adjusting components 43 are set on the worktable 1 and are used to adjust the distance between the straightening wheels 41. The positioning components 44 are connected to the adjusting components 43. The adjusting components 43 can simultaneously drive multiple sets of two adjacent straightening wheels 41 to move closer or further apart. The positioning components 44 can position the adjusted straightening wheels 41, avoiding the tedious operation of adjusting them one by one in the traditional way, improving straightening efficiency, and is suitable for rapid switching production of metal wires of different diameters.

[0025] Furthermore, the adjustment assembly 43 includes an adjustment frame 431, a drive rod 432, an extrusion plate 433, and a sliding block 434. The adjustment frame 431 is fixedly connected to one side of the worktable 1. An adjustment groove is provided on one side of the worktable 1. One end of the drive rod 432 is rotatably connected to the inner wall of the adjustment groove, and the other end of the drive rod 432 is rotatably connected to the inner wall of the adjustment frame 431. A turntable is fixedly connected to the end of the drive rod 432. The extrusion plate 433 and the drive rod 432 form a screw drive. Inclined grooves for sliding of the rotating rod 42 are equidistantly provided on the extrusion plate 433. The sliding block 434... 4. Fixedly connected to the bottom end of the extrusion plate 433, the bottom end of the inner wall of the adjusting frame 431 is provided with a sliding groove for the sliding block 434 to slide. The turntable can drive the drive rod 432 to rotate in both directions, so that the extrusion plate 433 can move back and forth in the horizontal direction under the limit of the sliding groove through the sliding block 434. Thus, the straightening wheel 41 can be extruded through the inclined groove opened on the extrusion plate 433, so that the straightening wheel 41 can be displaced inside the transverse groove, thereby realizing the adjustment of the distance between two adjacent straightening wheels 41, and can straighten metal wires of different diameters by traction.

[0026] Furthermore, the positioning assembly 44 includes a lifting rod 441, a sliding plate 442, a positioning rod 443, and a compression spring 444. The outer wall of the adjusting frame 431 has a lifting groove. The end of the lifting rod 441 is fixedly connected to the inner wall of the lifting groove. The sliding plate 442 is slidably inserted into the lifting rod 441. The positioning rod 443 is fixedly connected to the sliding plate 442. The outer wall of the turntable has equidistant positioning holes. The positioning rod 443 is slidably inserted into the inner cavity of the positioning hole. The compression spring 444 is sleeved on the outside of the lifting rod 441. One end of the compression spring 444 is fixedly connected to the slider 37, and the other end is fixedly connected to the top of the inner wall of the groove. The compression spring 444 always provides a stable elastic force to the positioning rod 443 through the sliding plate 442, thereby ensuring stable engagement between the positioning rod 443 and the positioning hole on the turntable. This allows for positioning of the adjusted drive rod 432, preventing accidental rotation that could cause the straightening wheel 41 to fail to adjust and affect the traction straightening quality.
