Description

Technical Field

[0001] This utility model relates to the field of cutting device technology, specifically a cutting device for a cold heading nut forming machine. Background Technology

[0002] Cold heading machines, as specialized equipment for the mass production of fasteners such as nuts and bolts, primarily function in efficient upsetting. During operation, the cutting device plays a crucial role, its main task being to precisely cut coiled wire into several small segments according to a predetermined length. These cut steel segments are then fed into the forming die by a feeding device, typically using a combination of a punch cutter and a shearing die, with the wire being cut by the rapid unidirectional movement of the cutter mount.

[0003] In actual production, when the punching cutter and shearing die are used together to cut cold heading nuts, the cutter will inevitably wear down after a long period of frequent cutting operations. As the wear of the cutter gradually intensifies, its cutting effect on cold heading nuts will be significantly affected, resulting in reduced cutting accuracy and poor practicality.

[0004] Therefore, a cutting device for a cold heading nut forming machine is needed to improve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a cutting device for a cold heading nut forming machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A cutting device for a cold heading nut forming machine includes a base, a mounting frame on the base surface of the base, a top plate on the outer wall of the mounting frame, a controller on the side wall of the top plate, a servo module on the inner wall of the top plate, a cutting blade on the moving end of the servo module, a grinding component on the inner wall of the mounting frame, a mounting bracket on one side of the mounting frame and located on the base surface of the base, and a drive motor on the outer wall of the mounting bracket.

[0008] The mounting bracket has symmetrically mounted fixed seats on its outer wall. The fixed seats have symmetrically arranged rotating shafts on their opposing outer walls. A gear timing belt is mounted on the outer wall of each rotating shaft, and a transmission wheel is mounted at one end of each shaft. A drive wheel is mounted on the transmission wheel via a transmission belt. One end of the drive wheel is connected to the drive shaft of a drive motor. Limiting blocks are mounted between the fixed seats and on the outer wall of the mounting bracket. One end of each limiting block is connected to the base surface of the base. A limiting groove is formed on the outer wall of each limiting block, and a nut wire is slidably connected to the inner wall of the limiting groove.

[0009] As a preferred embodiment of this utility model, the grinding assembly includes a mounting plate, which is mounted on the inner wall of the mounting frame. A servo motor is mounted on the inner wall of the mounting plate, and a mounting base is mounted on the drive shaft of the servo motor. A grinding block is mounted on the outer wall of the mounting base, wherein the grinding block is located on one side of the cutting blade.

[0010] As a preferred embodiment of this utility model, a connecting groove is provided on one side of the cutting blade and on the outer wall of the limiting clamping block, and the cutting blade is located on one side of the nut wire.

[0011] As a preferred embodiment of this utility model, the controller is electrically connected to the drive motor, the servo module, and the servo motor via wires.

[0012] As a preferred embodiment of this utility model, the gear timing belt is provided in two sets and is located on the outer wall of the fixed base respectively, and the gear timing belt is located on one side of the nut wire.

[0013] As a preferred embodiment of this utility model, the servo motor is provided in two sets and is located on the inner wall opposite to each other on the mounting plate, the grinding block is located on one side of the cutting blade, and the connection between the fixed seat and the rotating shaft is a rotatable connection.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. In this utility model, the grinding component in the cutting device of the cold heading nut forming machine is used, and the servo motor is controlled by the controller to operate. The drive shaft of the servo motor drives the grinding block to rotate through the mounting base. When the cutting blade is cut, it continues to move laterally under the drive of the servo module, so that the rapidly rotating grinding block grinds the surface of the cutting blade to keep the blade sharp. This helps to solve the problem that the blade will inevitably wear after a long period of frequent cutting operations. As the wear of the blade gradually increases, its cutting effect on the cold heading nut will be significantly affected, resulting in a decrease in cutting accuracy and poor practicality.

[0026] The working process of this utility model is as follows: When the cutting device of the cold heading nut forming machine designed in this scheme is working, the controller 4 is electrically connected to the drive motor 9, servo module 5, and servo motor 702 via wires, thereby energizing the device.

A grinding block 704 is installed on the outer wall of the mounting base 703. The grinding block 704 is located on one side of the cutting blade 6. Simultaneously, the controller 4 controls the servo... The motor 702 operates, causing the drive shaft of the servo motor 702 to drive the grinding block 704 to rotate via the mounting base 703. When the cutting blade 6 is completed, it continues to move laterally under the drive of the servo module 5, thereby causing the rapidly rotating grinding block 704 to grind the surface of the cutting blade 6, keeping the cutting edge sharp. This helps to solve the problem that the blade will inevitably wear after a long period of frequent cutting operations. As the wear of the blade gradually intensifies, its cutting effect on cold heading nuts will also be significantly affected, resulting in a decrease in cutting accuracy and poor practicality.
