Description

Technical Field

[0001] This application relates to the technical field of chamfering equipment, and particularly relates to a special chamfering equipment for high-strength steel wires. Background Art

[0002] Chamfering the edge of a steel wire is a processing procedure in machining to ensure that a uniform transition slope can be formed at the end of the steel wire, preventing damage to the structure due to stress concentration. However, due to the diversity of the specifications and dimensions of steel wires, when chamfering steel wires of different specifications and dimensions with existing chamfering equipment, it is necessary to adjust the relative position of the cutting tool according to the outer diameter of the steel wire. As a result, the operation of this chamfering equipment when chamfering steel wires of different specifications and dimensions is rather cumbersome, the efficiency is relatively low, and it greatly affects the processing progress, stability, and reliability of steel wire chamfering.

[0003] Therefore, there is an urgent need for a chamfering equipment for steel wire processing to solve the defects existing in the above-mentioned existing chamfering equipment when chamfering steel wires of different specifications and dimensions. Summary of the Invention

[0004] This application provides a special chamfering equipment for high-strength steel wires, which has the advantage of automatically adjusting the relative position of the cutting tool on it when chamfering steel wires of different specifications and dimensions, making the chamfering efficiency of steel wires of different specifications and dimensions relatively high. It is used to solve the problem that due to the diversity of the specifications and dimensions of steel wires, when chamfering steel wires of different specifications and dimensions with existing chamfering equipment, it is necessary to adjust the relative position of the cutting tool according to the outer diameter of the steel wire, resulting in rather cumbersome operation and relatively low efficiency of this chamfering equipment when chamfering steel wires of different specifications and dimensions.

[0005] To achieve the above object, the present application adopts the following technical solution: A special chamfering device for high-strength steel wires, including a main shaft box body with a driving device inside. The transmission shaft of the main shaft box body extends to the outside of the main shaft box body and is fixedly installed with a tool disk. The tool disk includes an outer disk body whose outer end face is fixedly connected to the transmission shaft of the main shaft box body. On the upper and lower sides of the right end inside the outer disk body, a set of linkage components for detecting and feedbacking the outer diameter of the steel wire are respectively movably clamped. In the middle of the left side inside the outer disk body, a tool block for cutting and chamfering the end of the steel wire is movably clamped. An inner disk body is movably sleeved inside the outer disk body, and an elastic connection is formed between the outer disk body and the inner disk body through an elastic member arranged on the inner wall of the outer disk body. An inner chute whose one side is in contact with the linkage component is opened inside the inner disk body. Thus, when the linkage components are extruded by steel wires of different specifications and sizes, under the extrusion of the linkage components, the inner disk body can be driven to rotate clockwise and compress the elastic member. And on one side of the outer end face of the inner disk body, a turbine tooth group meshing with the tool block is provided. When the inner disk body rotates clockwise, under the transmission of the turbine tooth group, the tool block can be forced to displace outward to a corresponding extent. Thus, the relative position of the tool block can be automatically adjusted according to the corresponding specifications and sizes of the steel wire. An end cover is provided at the end of the outer disk body to stably movably sleeve the inner disk body inside the outer disk body.

[0006] Further, the two sets of linkage components and the tool block are arranged in a circumferential array, and the positions of the two sets of linkage components are closer to the end cover relative to the position of the tool block. Thus, when the tool disk continuously approaches the steel wire under the action of the main shaft box body, the linkage components can first come into contact with the end of the steel wire to adjust the relative position relationship of the tool block. Then, during the continuous approach of the tool disk, the end of the steel wire is chamfered by the tool block.

[0007] Further, the linkage component includes a block movably clamped inside the outer disk body. A first inclined surface is provided at the bottom of one side of the block. Thus, under the extrusion of the end of the steel wire, the block can be forced to move outward. And a slider is fixedly installed at the top of one side of the block. The end of the slider is provided with a second inclined surface in contact with one side of the inner wall of the inner chute. And during the process that the block drives the slider thereon to move outward, under the extrusion of the second inclined surface, the inner disk body can be forced to rotate clockwise.

[0008] Further, a clamping mechanism is provided at the end of the main shaft box body on the side of the tool disk. Inside the clamping mechanism, a cylinder assembly for clamping the steel wire is provided. And a magnetic switch S1 for controlling the action of the cylinder assembly is provided on the outer wall of the cylinder assembly.

[0009] Further, a communication hole communicating with its inner cavity is provided on one side outside the clamping mechanism, and an optical fiber sensor and a time relay are provided thereon. When the steel wire is inserted into the clamping mechanism, the optical fiber sensor detects the steel wire and transmits a signal to the time relay, and after the steel wire reaches a predetermined position through a delay system, the main shaft box body is started, and then chamfering operation is performed on the clamped steel wire.

[0010] Further, a baffle for restricting the insertion depth of the steel wire into the clamping mechanism is pin-connected to the inner side end of the clamping mechanism, and one end of the baffle is pin-connected to a baffle cylinder provided at the top of the inner side end of the clamping mechanism, and a magnetic switch S2 for controlling its lifting or lowering action is provided on the outer wall of the baffle cylinder. Thus, when the end of the steel wire abuts against the baffle, the baffle can be lifted by the baffle cylinder, and the depth of the steel wire penetrating into the clamping mechanism can be adjusted accordingly.

[0011] Further, a feed cylinder is fixedly installed on one side of the end face of the main shaft box body, and the output shaft of the feed cylinder is in transmission connection with the transmission shaft in the main shaft box body. Thus, the transmission shaft in the main shaft box body and the tool disc thereon can be driven by the feed cylinder to move left and right, so as to perform chamfering operation on the end face of the steel wire clamped by the clamping mechanism, and a magnetic switch S3 for controlling the left or right movement of the output shaft thereon is provided on the outer wall of the feed cylinder.

[0012] Further, a damper corresponding to the moving position of the output shaft of the feed cylinder is provided on one side of the end face of the main shaft box body. Thus, when the output shaft of the feed cylinder comes into contact with the end of the damper, the speed of the transmission shaft in the main shaft box body and the tool disc thereon moving to the left can be effectively slowed down, preventing impact damage to the tool block due to excessive speed.

[0013] The beneficial effects of the present invention are as follows: A special chamfering device for high-strength steel wires provided by the present application, for the setting of the tool disc and the structures thereon, when the linkage assembly is extruded by steel wires of different specifications and sizes, under the extrusion action of the linkage assembly, the inner disc body can be driven to rotate clockwise and compress the elastic member, and under the transmission action of the turbine gear set, the tool block can be forced to displace outward to a corresponding extent. Thus, the relative position of the tool block can be automatically adjusted according to the corresponding specifications and sizes of the steel wires, so that the chamfering efficiency for steel wires of different specifications and sizes is relatively high, and the operation is simple and the use is convenient.

Specific embodiments

[0016] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0017] As Figure 1 shown, a special chamfering device for high-strength steel wires includes a main shaft housing 1 with a driving device inside. The transmission shaft of the main shaft housing 1 extends to the outside of the main shaft housing 1 and is fixedly installed with a tool disc 2. As Figure 3 、 Figure 4 shown, the tool disc 2 includes an outer disc body 9 whose outer end face is fixedly connected to the transmission shaft of the main shaft housing 1. On the upper and lower sides of the right end inside the outer disc body 9, a set of linkage assemblies 11 for detecting and feedback the outer diameter of the steel wire are movably clamped respectively. And in the middle of the left side inside the outer disc body 9, a tool block group 10 for cutting and chamfering the end of the steel wire is movably clamped. As Figure 5 shown, an inner disc body 12 is movably sleeved inside the outer disc body 9, and an elastic connection is formed between the outer disc body 9 and the inner disc body 12 through an elastic member 16 arranged on the inner wall of the outer disc body 9. As Figure 6 、 Figure 7As shown in the figure, an inner chute 14 is provided inside the inner disk body 12, with one side in contact with the linkage assembly 11. Thus, when the linkage assembly 11 is squeezed by steel wires of different specifications and dimensions, under the squeezing action of the linkage assembly 11, the inner disk body 12 can be driven to rotate clockwise and compress the elastic member 16. On one side of the outer end face of the inner disk body 12, a turbine tooth group 15 that engages and drives the tool block 10 is provided. When the inner disk body 12 rotates clockwise, under the driving action of the turbine tooth group 15, the tool block 10 can be forced to displace outward to a corresponding extent, and thus the relative position of the tool block 10 can be automatically adjusted according to the corresponding specifications and dimensions of the steel wire. An end cover 13 is provided at the end of the outer disk body 9 to stably and movably sleeve the inner disk body 12 inside the outer disk body 9.

[0018] As Figure 5 shown, in this technical solution, the two linkage assemblies 11 and the tool block 10 are arranged in a circumferential array, and the positions of the two linkage assemblies 11 are closer to the end cover 13 relative to the position of the tool block 10. Thus, when the tool disk 2 continuously approaches the steel wire under the action of the main shaft housing 1, the linkage assembly 11 can first come into contact with the end of the steel wire to adjust the relative position relationship of the tool block 10, and then during the continuous approach of the tool disk 2, the end of the steel wire can be chamfered by using the tool block 10.

[0019] As Figure 4 、 Figure 6 and Figure 8 shown, in this technical solution, the linkage assembly 11 includes a block 17 movably clamped inside the outer disk body 9. A first inclined surface 18 is provided at the bottom on one side of the block 17. Thus, under the squeezing action of the end of the steel wire, the block 17 can be forced to move outward. A slider 19 is fixedly installed at the top on one side of the block 17, and a second inclined surface 20 that contacts one side of the inner wall of the inner chute 14 is provided at the end of the slider 19. During the process of the block 17 driving the slider 19 thereon to move outward, under the squeezing action of the second inclined surface 20, the inner disk body 12 can be forced to rotate clockwise.

[0020] As Figure 1 shown, in this technical solution, a clamping mechanism 3 is provided at the end of the main shaft housing 1 on the side of the tool disk 2. A cylinder assembly for clamping the steel wire is provided inside the clamping mechanism 3, and a magnetic switch S1 for controlling the action of the cylinder assembly is provided on the outer wall of the cylinder assembly.

[0021] As Figure 2As shown, in this technical solution, a communication hole 8 communicating with its inner cavity is provided on one side outside the clamping mechanism 3, and an optical fiber sensor and a time relay are provided thereon. When the steel wire is inserted into the clamping mechanism 3, the optical fiber sensor detects the steel wire and transmits a signal to the time relay, and after the steel wire reaches a predetermined position through the delay system, the main spindle box 1 is started, and then chamfering operation is performed on the clamped steel wire.

[0022] As Figure 1 , Figure 2 shown, in this technical solution, a baffle 5 for restricting the insertion depth of the steel wire into the clamping mechanism 3 is pin-connected to the inner side end of the clamping mechanism 3, and one end of the baffle 5 is pin-connected to a baffle cylinder 4 provided at the top of the inner side end of the clamping mechanism 3, and a magnetic switch S2 for controlling its lifting or lowering action is provided on the outer wall of the baffle cylinder 4. Thus, when the end of the steel wire abuts against the baffle 5, the baffle 5 can be lifted by the baffle cylinder 4, and the depth of the steel wire penetrating into the clamping mechanism 3 can be adjusted accordingly.

[0023] As Figure 1 shown, in this technical solution, a feed cylinder 6 is fixedly installed on one side of the end face of the main spindle box 1, and the output shaft of the feed cylinder 6 is in transmission connection with the transmission shaft in the main spindle box 1. Thus, the transmission shaft in the main spindle box 1 and the tool disk 2 thereon can be driven to move left and right by the feed cylinder 6 to perform chamfering operation on the end face of the steel wire clamped by the clamping mechanism 3, and a magnetic switch S3 for controlling the left or right movement of the output shaft thereon is provided on the outer wall of the feed cylinder 6.

[0024] As Figure 1 , Figure 4 shown, in this technical solution, a damper 7 corresponding to the moving position of the output shaft of the feed cylinder 6 is provided on one side of the end face of the main spindle box 1. Thus, when the output shaft of the feed cylinder 6 comes into contact with the end of the damper 7, the moving speed of the transmission shaft in the main spindle box 1 and the tool disk 2 thereon moving to the left can be effectively slowed down, preventing impact damage to the tool block 10 due to excessive speed.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to these embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
