[0051] In the above scheme, the fixed frame 1 is the supporting frame of the whole device, and a slide groove 801 is provided on it, and the direction of the slide groove 801 is perpendicular to the axial direction of the first mold 13, so as to facilitate the lateral movement of the first mold 13. The first mold 13 is slidably arranged in the slide groove 801 on the fixed frame 1 through the slide rail 8. When stamping is required, the first mold 13 can move along the slide groove 801 to a position coaxial with the second mold 15. The second mold 15 is installed on the fixed frame 1 and can slide along the axial direction parallel to the first mold 13 to meet the stamping requirements of bars of different lengths or shapes. The feeding part 7 is located on one side of the fixed frame 1 and has a feeding trough 704 for placing the bars to be stamped. When the first mold 13 slides to one side, it can be coaxially arranged with the feeding trough 704, which is convenient for positioning the bars and preparation before stamping. During operation, the bars to be processed are first placed in the feeding trough 704. Then, the first die 13 moves to a position coaxial with the feeding chute 704 through the slide 801. At this time, the bar enters the first die 13 and is positioned by the first die 13. Next, the second die 15 moves in the axial direction thereof and cooperates with the first die 13 to complete the stamping action and form the screw head. After the stamping is completed, the first die 13 slides to the initial position again to facilitate the next loading and stamping.

[0052] Furthermore, the fixing frame 1 includes a first plate body 101, a second plate body 102, a third plate body 103 and a connecting rod 105.

[0053] In the above scheme, the first plate body 101, the second plate body 102 and the third plate body 103 constitute the frame of the fixed frame 1, and the first plate body 101, the second plate body 102 and the third plate body 103 are connected by a connecting rod 105 to form a stable structure. The first plate body 101 and the third plate body 103 are outer plates, and the second plate body 102 is located in the middle, which plays a supporting and connecting role. The number of connecting rods 105 can be selected according to actual needs, but at least the stability and strength of the structure should be guaranteed. The connecting rod 105 passes through the first plate body 101, the second plate body 102 and the third plate body 103 in sequence, and connects them tightly together to form an integral frame structure. The slide rail 8 is arranged on the first plate body 101, and has a through groove 1011, which is connected to the slide groove 801 on the fixed frame 1. The first mold 13 can slide along the through groove 1011 and the slide groove 801 on the slide rail 8, so as to realize movement between different positions. The slider 9 is arranged on the slide rail 8 and can slide freely along the slide rail 8. The first mold 13 is installed on the slider 9, so that when the slider 9 moves on the slide rail 8, it will drive the first mold 13 to move together. The slider 9 makes the movement of the first mold 13 more stable.

[0054] When the first mold 13 needs to be moved to be coaxial with the feeding trough 704, the operator or the automated system controls the slide block 9 to move along the slide rail 8, thereby driving the first mold 13 to move to the specified position. During the stamping operation, the slide block 9 is controlled again to drive the first mold 13 to move to a position coaxial with the second mold 15. At this time, the relative positions of the two molds are fixed, and the stamping operation is performed. After the stamping is completed, the slide block 9 moves again to bring the first mold 13 back to the initial position to prepare for the next round of feeding and stamping.

[0055] Furthermore, it also includes: a first driving member 2, which is provided with one end of a slide rail 8, and the first driving member 2 is used to drive the slider 9 to move; a second driving member 3, which is provided on the third plate 103, and the second mold 15 is provided on the driving end of the second driving member 3, and the second driving member 3 is used to drive the second mold 15 to move along the axial direction parallel to the first mold 13.

[0056] In the above scheme, the first driving member 2 is arranged at one end of the slide rail 8, and the function of the first driving member 2 is to drive the slider 9 to move along the slide groove 801 on the slide rail 8.

The second driving member 3 can also be a motor, a cylinder or other linear driving device, which is used to drive the second mold 15 to move along the axis parallel to the first mold 13 to adjust the position of the second mold 15 to meet different stamping requirements. When stamping preparation is required, the first driving member 2 is started, and the slider 9 is driven to move along the slide rail 8, thereby driving the first mold 13 to reach a position coaxial with the feeding trough 704. After the feeding is completed, the first driving member 2 is started again to move the first mold 13 to a position aligned with the second mold 15. While the first mold 13 is in place, the second driving member 3 adjusts the position of the second mold 15 according to a preset program or the operator's instructions. After the first die 13 and the second die 15 are aligned, the second die 15 moves toward the first die 13, and the two cooperate to complete the stamping action. After the stamping is completed, the second die 15 is reset, and the first die 13 is also driven back to the initial position by the first driving member 2 to prepare for the next round of feeding and stamping.

The sliding plate is slidably arranged on the bracket 701, allowing the sliding plate to slide back and forth on the guide rail 17 of the bracket 701, so as to adjust the relative position between the loading trough 704 and the first mold 13, and ensure that the rod can be accurately aligned with the first mold 13. The deflection baffle 702 is rotatably arranged on the sliding plate. After the rod is placed in the loading trough 704, the deflection baffle 702 can be rotated to an appropriate position to limit the rod, prevent the rod from being offset during the movement, and ensure the loading accuracy.

[0059] Workflow: 1. Loading preparation: The operator or the automated manipulator places the bar into the loading trough 704, at which time the deflection baffle 702 is in the open state, which facilitates the placement of the bar. 2. Bar limiting: After the bar is placed, the deflection baffle 702 rotates to the closed position to limit the position of the bar. 3. Alignment with the first mold 13: By moving the sliding plate on the bracket 701, the position of the loading trough 704 is adjusted so that the bar is aligned with the center of the first mold 13, ready for loading.

When the first push rod 6 moves along the guide rail 17, the pushing end 602 can accurately push the bar in the upper trough 704 into the first mold 13 to prepare for stamping. The third driving member 4 is arranged on the third plate body 103 to drive the movement of the first push rod 6. One end of the first push rod 6 is connected to the driving end of the third driving member 4. When pushing is required, the third driving member 4 is started to push the first push rod 6 to move along the guide rail 17, thereby pushing the bar into the first mold 13. Workflow 1. Preparation stage: The bar is placed in the feeding trough 704, the deflection baffle 702 is limited, and the first die 13 moves to be coaxial with the feeding trough 704. 2. Pushing stage: The third driving member 4 is started, driving the first push rod 6 to move along the guide rail 17, and the push end 602 pushes the bar into the first die 13. 3. Stamping stage: The first die 13 is aligned with the second die 15 and stamped to form a screw head. 4. Unloading and repeating: After the stamping is completed, the first push rod 6 is reset to prepare for the next push, and the entire device enters the next cycle.

When the punched screw is released from the loading groove 704, the hook groove 1601 can hook the screw and take it out. The first push rod 6 moves in the reverse direction under the drive of the third driving member 4. At this time, the hook groove 1601 on the unloading lever 16 is aligned with the screw, ready to hook it out. As the first push rod 6 continues to move in the reverse direction, the hook groove 1601 of the unloading lever 16 hooks the screw and takes it out of the first mold 13, completing the unloading action.

[0064] Furthermore, it also includes: a cylinder 14, which is arranged on the back side of the first mold 13; a second push rod 12, which is slidably arranged in the cylinder 14, and the second push rod 12 is used to assist in the stamping and forming of the rod and for unloading the rod; a mounting frame 10, which is arranged on the side of the first plate 101 away from the first mold 13; a fourth driving member 11, which is arranged on the mounting frame 10, and the fourth driving member 11 is used to drive the second push rod 12 to move.
