[0021] The examples are as follows:

[0022] The utility model provides Figure 1-4 The cold heading machine shown in the figure can be headed at both ends, comprising a cold heading machine base 1 and a feeding mechanism 2 installed at the middle position of the top of the cold heading machine base 1;

[0023] The feeding mechanism 2 includes limiting slide grooves 201 provided on both sides of the top of the cold heading machine base 1, the inner walls of the two limiting slide grooves 201 are interspersed with support modules 202, one side of the top of one of the support modules 202 is fixedly provided with a first electric telescopic rod 203, the output end of the first electric telescopic rod 203 is fixedly provided with a clamping plate 204, a feeding base 205 is fixedly provided at the edge of one side of the top of the cold heading machine base 1, a conveyor belt 206 is installed at one end of the inner wall of the feeding base 205, a limiting plate 207 is fixedly provided at the edge of the inner wall of the feeding base 205 located at one end of the conveyor belt 206, a guide plate 208 is fixedly provided at the edge of one side of the feeding base 205, an anti-slip pad 209 is fixedly provided at one end of the bottom of the inner wall of the feeding base 205, a second electric telescopic rod 210 is fixedly provided on one side of the inner wall of the two limiting slide grooves 201, and the two The output ends of the second electric telescopic rods 210 are respectively fixedly connected to one side of the two support modules 202, and the limit plate 207 is tilted at the upper end of the inner wall of the loading base 205, so that the blanks therein cannot contact the top of the conveyor belt 206, and can only enter the lower area of ​​the conveyor belt 206 through the gap under the limit plate 207. During the conveying process, the conveyor belt 206 cooperates with the anti-skid pad 209 to roll with the blanks on the inner wall of the loading base 205 in sequence until it rolls to the edge of the conveyor belt 206 and then rolls to the upper ends of the two support modules 202 below through the guide plate 208. The loading base 205 is located in the area below the conveyor belt 206 and is designed to be in an inclined state. The anti-skid pad 209 is fixed in this area. The anti-skid pad 209 can increase the friction with the blanks to prevent the blanks from sliding down due to the smooth inner wall.

[0024] Furthermore, a discharge chute 3 is provided at the top of the cold heading machine base 1 in the middle of the two limiting slide grooves 201 , and a through groove is provided on one side of the outer wall of the cold heading machine base 1 , and the inner wall of the through groove is connected to the inner wall of the discharge chute 3 .

[0025] A clamping rail 4 is fixedly provided on one side of the cold heading machine base 1 at the lower edge of the through groove, and a collecting box 5 is inserted through the inner wall of the clamping rail 4. A handle 6 is fixedly provided on one side of the collecting box 5, and the inner wall of the discharge chute 3 is designed to be in an inclined state, so that the processed workpieces can slide into the collecting box 5. The collecting box 5 is connected with the clamping rail 4 through an interlaced manner and can be quickly disassembled, so as to facilitate the collection of workpieces.

[0026] Furthermore, both sides of the inner wall of the cold heading machine base 1 are provided with slots 7 , and two stamping bases 8 are slidably provided between the inner walls of the four slots 7 .

[0027] A cold heading die 9 is fixedly provided on one side of the two stamping bases 8, and a hydraulic cylinder 10 is fixedly provided on the edges of both sides of the cold heading machine base 1. Push rods 11 are inserted into the output ends of the two hydraulic cylinders 10, and one end of the two push rods 11 is fixedly connected to the other side of the two stamping bases 8 respectively. The stamping base 8 is pushed by the hydraulic cylinder 10 and the push rod 11 so that the cold heading dies 9 at both ends of the cold heading machine base 1 can perform two-end upsetting on the blank fixed on the support module 202.

[0028] Working principle: When using the cold heading machine with two ends capable of heading in the present design, during the cold heading process, the blank to be cold headed at both ends is placed on the inner wall at one end of the loading base 205, and is limited by its upper limit plate 207 so that it can only move below the conveyor belt 206, and the inner wall at one end of the loading base 205 is designed to be in an inclined state. After the conveyor belt 206 is running, the non-slip pad 209 is used to flatten the blanks one by one inside the loading base 205, and when the blank at the head end moves to the edge along the conveyor belt 206, it will automatically roll onto the guide plate 208 when it is separated from the extrusion of the conveyor belt 206, and then be introduced by the guide plate 208 to the support module 202 at the lower end. Before the blank falls, the support module 202 is pushed by the second electric telescopic rod 210. The workpiece is moved in the limiting slide 201 and squeezed together to support the blank, and then the first electric telescopic rod 203 is started to make the upper clamping plate 204 descend to squeeze and fix the blank, so that it is not easy to shift during the cold heading process and remains stable. In this design scheme, it is only necessary to place the blanks uniformly inside one end of the loading base 205, and then the conveyor belt 206 and the anti-slip pad 209 can be used for single transfer and clamping and fixing. After processing the outer wall, the support module 202 is removed, the workpiece falls into the unloading trough 3 and slides through the through groove to the collection box 5 for collection. After it is full, it can be removed from the rail 4 through the handle 6 to process the workpieces therein. There is no need for staff to place the blanks one by one, which improves processing efficiency and reduces the workload of staff.
