The "cold heading machine for bolt processing" disclosed by the publication number "CN218798894U" has solved the technical disadvantage of requiring staff to manually clean the lubricating oil attached to the surface of the bolt. However, in actual use, cold heading machines with similar structures still have many defects. For example, most of the loading and unloading are done manually by staff during operation. Manual loading and unloading will increase the workload of personnel and bring greater physical burden to personnel.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-7 The utility model provides a technical solution: a cold heading machine for bolt processing, comprising a support mechanism 1 and a cold heading mechanism 2 and a forming mechanism 3 which are assembled on the top of the support mechanism 1 and are distributed in the front and rear. The support mechanism 1 comprises a base 101, and a plurality of support plates 4 are fixedly installed on the rear side of the top of the base 101. A guide ring tube 401 is fixedly installed on the top of each support plate 4. The forming mechanism 3 comprises a clamping seat 301 and a discharge box 7. A plurality of through holes 302 corresponding to the guide ring tube 401 are arranged inside the clamping seat 301. A feeding rack 5 is fixedly installed on the back of the clamping seat 301. A plurality of feeding wheels 501 corresponding to the guide ring tube 401 are rotatably installed inside the feeding rack 5. The through holes 302 are arranged on the inside of the clamping seat 301. 02 is fixedly installed with a forming mold 304 on the front side, a limiting slot 303 is arranged inside the clamping seat 301, a limiting seat 801 is slidably installed inside the limiting slot 303, two groups of limiting hydraulic rods 8 connected with the limiting seat 801 at the output end are fixedly installed on the top of the clamping seat 301, two groups of cutting hydraulic rods 6 are fixedly installed on the front side of the top of the clamping seat 301, and a cutting knife 601 is fixedly installed on the output end of the cutting hydraulic rod 6, and the cold heading mechanism 2 includes a cold heading seat 201, two groups of cold heading hydraulic rods 202 are fixedly installed inside the cold heading seat 201, and a cold heading plate 203 used in conjunction with the forming mold 304 is fixedly installed at the output end of the cold heading hydraulic rod 202.

[0025] Based on the above-mentioned structural setting, the cold heading machine for bolt processing is composed of a supporting mechanism 1, a cold heading mechanism 2 and a forming mechanism 3, wherein the supporting mechanism 1 is a supporting and fixing mechanism when the cold heading machine is in operation, and the stability of the cold heading machine during operation is ensured by means of the supporting mechanism 1, the cold heading mechanism 2 is an extrusion driving mechanism of the cold heading machine, and the forming mechanism 3 is a forming processing mechanism for the bolt. Specifically, during the working process, the base 101 can support and fix the bottom of the cold heading machine when it is in operation, and the support plate 4 fixes the guide ring tube 401. The guide ring 401 is fixedly installed on the rear side of the top of the base 101, and the guide ring 401 can be used to guide and limit the path of the raw material when it enters the cold heading machine to ensure the stability of the raw material when it enters the cold heading machine. The multiple groups of feeding wheels 501 installed in the feeding rack 5 can rotate and clamp the raw material, so that the rotation of the feeding wheel 501 can drive the raw material to be inserted into the through hole 302 in the clamping seat 301. When the raw material passes through the through hole 302, one end extends to the inside of the forming mold 304, thereby achieving the cold heading machine. The function of automatic feeding during the operation of the upsetting machine avoids the need for manual feeding by personnel, which increases the workload and physical burden, and also avoids the situation where manual feeding by personnel takes up a lot of time and affects the work efficiency. The limit hydraulic rod 8 can push and lower the limit seat 801 in the limit slot 303 by extending, so that the raw material inside the clamping seat 301 can be pressed and fixed by the descent of the limit seat 801. The two sets of cold heading hydraulic rods 202 installed on the cold heading seat 201 can push the cold heading plate 203 by extending, and the raw material in the forming mold 304 can be extruded and formed by the pushing of the cold heading plate 203, so that the bolts can be processed. After processing and forming, the feeding wheel 501 can push the bolts out of the forming mold 304 by driving the raw material to move. The cutting hydraulic rod 6 can cut the pushed bolts by extending the cutting knife 601 to descend, and the discharge box 7 can recover and discharge the cut bolts, thereby realizing the function of automatic discharging of the processed bolts.

[0026] Furthermore, rollers 702 are rotatably mounted on both sides of the discharge box 7, an output belt 703 is rotatably mounted outside the rollers 702, and a discharge motor 701 whose output end is connected to the rollers 702 is fixedly mounted on one side of the discharge box 7. The discharge motor 701 can drive the output belt 703 to rotate through the rollers 702, so that the bolts recovered in the discharge box 7 can be automatically discharged.

[0027] Furthermore, a feeding motor 503 is fixedly installed on the other side of the feeding frame 5, and an anti-skid pattern 502 is provided on the outer wall of the feeding wheel 501. The output end of the feeding motor 503 is fixedly connected to the feeding wheel 501, so that the feeding motor 503 can drive the feeding wheel 501 to rotate, which is convenient for the feeding wheel 501 to automatically feed the cold heading machine when operating. The anti-skid pattern 502 increases the friction force of the outer wall of the feeding wheel 501, and improves the stability of the feeding wheel 501 when driving the raw material to feed.

[0028] Furthermore, the inner wall of the guide ring tube 401 is fixedly provided with bristles 402. The bristles 402 can clean the outer wall of the raw material passing through the inner part of the guide ring tube 401, thereby preventing foreign matter from adhering to the outer wall of the raw material and affecting the processing of the cold heading machine.

[0029] Furthermore, the bottom of the limit seat 801 is provided with multiple groups of slots 802 corresponding to the limit slots 303, and the inner walls of the slots 802 are all fixedly installed with anti-skid protrusions 803. The slots 802 can be engaged with the outer wall of the raw material, and the anti-skid protrusions 803 increase the friction force of the inner wall of the slots 802, thereby improving the stability of the limit seat 801 when pressing down and locking the raw material.

[0030] Furthermore, two sets of mounting holes 102 are provided on the front and rear sides of the top of the base 101, and rubber pads 103 are fixedly installed on the front and rear sides of the bottom of the base 101. The mounting holes 102 can fix the base 101 by bolts, and the rubber pads 103 can buffer and reduce shock when the base 101 is installed, thereby improving the stability of the cold heading machine during installation.
