Description

Technical Field

[0001] This utility model relates to the technical field of wire processing, and in particular to a metal wire drawing wheel. Background Technology

[0002] Metal wire drawing machines are key equipment in wire processing. They guide the wire through multiple dies in sequence using drawing wheels (or guide wheels, tower wheels) to achieve continuous drawing and forming of the wire. The drawing wheels are the components that directly contact the wire and transmit power.

[0003] Among them, the existing wire drawing wheels are usually of integral structure, which has the advantages of low manufacturing cost and high structural strength. However, when a wire channel needs to be replaced due to wear, the entire wire drawing wheel must be scrapped and replaced, which not only wastes the entire component, but also increases the actual use cost. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, the purpose of this utility model is to propose a metal wire drawing wheel that connects and locks the wheel tower to the shaft through a locking component. When the wire groove on the wheel tower wears, the worn wheel tower can be separated from the shaft and a new wheel tower can be replaced without replacing the entire component, thus reducing its usage cost.

[0006] To achieve the above objectives, this utility model proposes a metal wire drawing wheel, comprising a shaft, a wheel tower, a locking assembly, and a positioning assembly. The shaft has locking grooves at its upper and lower ends, the wheel tower is inserted into the shaft, and the wheel tower has connecting grooves at its upper and lower ends. The locking assembly includes two symmetrically arranged locking blocks, two symmetrically arranged push rods, a locking groove, a sliding rod, a connecting groove, a sliding groove, and an adjusting assembly. The two symmetrically arranged locking grooves are respectively located at the upper and lower ends of the shaft, and the two symmetrically arranged connecting grooves are respectively located at the upper and lower ends of the wheel tower. The two symmetrically arranged locking blocks are slidably connected to the connecting grooves, with their inner sides inserted into the locking grooves. The two symmetrically arranged push rods are respectively located on the sides of the two locking blocks that are far apart, and are slidably connected to the wheel tower. The sliding rod is fixedly connected to the sides of the locking blocks that are far apart, and the sliding groove is located on the sides of the sliding rods that are close together. The push rod is slidably connected to the sliding groove. The adjusting assembly is located at the front end of the wheel tower, and the positioning assembly is located on the shaft.

[0007] In addition, the metal wire drawing wheel proposed above according to this utility model may also have the following additional technical features: Specifically, the adjustment assembly includes a connecting rod and a lead screw, wherein the connecting rod is slidably connected to the front end inside the wheel tower, the connecting rod is fixedly connected to the front ends of the two push rods, the lead screw is rotatably connected to the inside of the wheel tower, the front end of the lead screw extends to the front side of the wheel tower, and the connecting rod is threaded onto the lead screw.

[0008] Specifically, the positioning component includes a positioning groove and a positioning rod, wherein the positioning groove is formed inside the wheel turret, the positioning rod is fixedly connected to the shaft, and the positioning rod is inserted into the positioning groove.

[0009] Specifically, a mounting plate is fixedly connected to the rear end of the shaft.

[0010] Compared with the prior art, the technical solution provided by this utility model has the following beneficial effects: The metal wire drawing wheel of this utility model can easily replace the wheel tower through the locking component, which improves the replacement efficiency. When the wheel tower needs to be disassembled and replaced, the push rod is controlled to slide by adjusting the component, which drives the locking blocks to move away from each other and be stored inside the wheel tower. Then the wheel tower can be easily removed for replacement. The operation is simple and quick, and it avoids the situation where the entire component is scrapped due to local wear of the traditional integral wire drawing wheel, thus reducing the cost of use.

[0014] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0015] The metal wire drawing wheel of this utility model embodiment will be described below with reference to the accompanying drawings.

[0016] like Figures 1-5 As shown, the metal wire drawing wheel of this utility model embodiment may include a shaft 1, a locking groove 31, a wheel tower 2, a connecting groove 32, a locking component 3, and a positioning component 4.

[0017] Among them, the upper and lower ends of the shaft 1 are provided with locking grooves 31; The wheel tower 2 is inserted into the shaft 1, and the upper and lower ends of the wheel tower 2 are provided with connecting grooves 32.

[0018] Locking component 3 is installed inside wheel tower 2.

[0019] Positioning component 4 is mounted on shaft 1.

[0020] Specifically, the shaft 1 is the main body of the device, and the rear end of the wheel tower 2 has a slot. The wheel tower 2 is inserted into the shaft 1 through the slot. The outside of the wheel tower 2 is a wheel body with several wire grooves of different diameters. The locking component 3 is used to lock the wheel tower 2 to the outside of the shaft 1. The wheel tower 2 can be easily replaced by the locking component 3, which improves the replacement efficiency. The positioning component 4 is used to transmit the axial rotational force from the shaft 1 to the wheel tower 2, thereby driving the wheel tower 2 to rotate.

[0021] The locking assembly 3 includes two symmetrically arranged locking blocks 33, two symmetrically arranged push rods 34, a slide rod 35, a slide groove 36, and an adjustment assembly 37. The two symmetrically arranged locking blocks 33 are slidably connected inside the connecting groove 32, and the inner side of the locking blocks 33 is inserted into the locking groove 31. The two symmetrically arranged push rods 34 are respectively located on the side of the two locking blocks 33 that are far apart from each other. The push rods 34 are slidably connected inside the wheel tower 2. The slide rod 35 is fixedly connected on the side of the locking blocks 33 that are far apart from each other. The slide groove 36 is opened on the side of the slide rods 35 that are close to each other. The push rod 34 is slidably connected inside the slide groove 36. The adjustment assembly 37 is located at the front end inside the wheel tower 2.

[0022] It should be noted that the outer front part of the locking block 33 is an inclined surface, and the inner rear part of the two push rods 34 is also an inclined surface. When the push rod 34 slides backward, the two locking blocks 33 are pushed closer to each other under the action of the inclined surface. The wheel tower 2 is fixed to the outside of the shaft rod 1 by inserting the locking block 33 into the locking groove 31. T-shaped sliding rods 35 are fixedly connected to the inclined surfaces on the outer front parts of the two locking blocks 33. T-shaped sliding grooves 36 are opened on the inclined surface of the push rod 34. When the push rod 34 slides forward, the two locking blocks 33 are driven away from each other by the connection of the sliding rod 35 and the sliding groove 36. The locking block 33 is stored inside the wheel tower 2, which makes it easy to remove the wheel tower 2. The adjusting component 37 is used to control the movement of the push rod 34 relative to the wheel tower 2.

[0023] Specifically, in the initial state, the locking block 33 is housed inside the connecting groove 32, and the push rod 34 is located at the front. First, the wheel tower 2 is inserted into the shaft 1 through the positioning component 4 to ensure that the locking block 33 can be aligned with the locking groove 31. Then, the positioning component 4 controls the two push rods 34 to slide backward. While the push rods 34 slide backward, the slide groove 36 pushes the slide rod 35. Because the slide rod 35 and the locking block 33 are restricted by the connecting groove 32, the lateral movement force of the push rod 34 is converted into a force that pushes the locking block 33 to move downward. Under the action of this force, the locking block is inserted into the locking groove 31, locking the wheel tower 2 onto the shaft 1 and preventing the wheel tower 2 from moving axially.

[0024] When the wheel tower 2 needs to be disassembled and replaced, the two push rods 34 are controlled to slide forward by adjusting the component 37. When the push rods 34 are pushed forward, the slide rod 35 and the slide groove 36 drive the two locking blocks 33 to move away from each other under the guidance of the connecting groove 32. The locking blocks 33 are stored inside the connecting groove 32, releasing the lock on the wheel tower 2. Then the wheel tower 2 can be easily removed for replacement.

[0025] In one embodiment of this utility model, such as Figure 2 As shown, the adjustment assembly 37 includes a connecting rod 371 and a lead screw 372. The connecting rod 371 is slidably connected to the front end of the wheel tower 2 and is fixedly connected to the front end of the two push rods 34. The lead screw 372 is rotatably connected to the inside of the wheel tower 2 and extends to the front side of the wheel tower 2. The connecting rod 371 is threadedly connected to the lead screw 372.

[0026] It should be noted that a cavity is opened at the front end of the inner side of the wheel tower 2, the connecting rod 371 is slidably connected inside the cavity, the front end of the push rod 34 extends into the cavity, and the push rod 34 is fixedly connected to the upper and lower ends of the rear side of the connecting rod 371. The front end of the lead screw 372 extends to the front side of the wheel tower 2 and forms the operating end.

[0027] Specifically, by rotating the lead screw 372, the connecting rod 371 is driven to slide inside the cavity. The connecting rod 371 drives the push rod 34 to move synchronously. The lateral movement of the push rod 34 drives the locking block 33 to lock or unlock the wheel tower 2.

[0028] In one embodiment of this utility model, such as Figure 5 As shown, the positioning component 4 includes a positioning groove 41 and a positioning rod 42. The positioning groove 41 is formed inside the wheel tower 2, and the positioning rod 42 is fixedly connected to the shaft 1 and inserted into the positioning groove 41.

[0029] It should be noted that, with the cooperation of the positioning groove 41 and the positioning rod 42, the locking block 33 can be accurately inserted into the locking groove 31 after the wheel tower 2 is inserted into the outside of the shaft 1 each time. Furthermore, with the connection of the positioning groove 41 and the positioning rod 42, the wheel tower 2 is driven to rotate synchronously by the circumferential motion of the shaft 1.

[0030] In one embodiment of this utility model, such as Figure 2 As shown, the rear end of shaft 1 is fixedly connected to mounting plate 5.

[0031] Specifically, several fixing bolts are inserted through the mounting plate 5, and the mounting plate 5 is installed on the wire drawing machine by fixing bolts.

[0032] In summary, the metal wire drawing wheel of this utility model embodiment allows for convenient replacement of the wheel tower through a locking component, improving replacement efficiency. When the wheel tower needs to be disassembled and replaced, the push rod is controlled to slide by adjusting the component, causing the locking blocks to move away from each other and be stored inside the wheel tower. After that, the wheel tower can be easily removed for replacement. The operation is simple and quick, and it avoids the situation where the entire component is scrapped due to local wear of traditional integral wire drawing wheels, thus reducing the cost of use.
