Description

Technical Field

[0001] The utility model relates to the technical field of punching dies, in particular to a sub-groove-shaped notch punching die. Background Art

[0002] Notching generally refers to the technology of using stamping dies or cutting tools to create notches or cuts in materials during metal processing, plastic molding or other material processing. This technology is widely used in the manufacture of various parts and products, such as metal sheets, plastic sheets, etc., to meet specific engineering design requirements.

[0003] In the existing sub-groove notch punching process, the workpiece that has been preliminarily processed needs to be placed inside the punching die. The inner wall of the punching die will have the same shape as the workpiece. At the position where punching is required, a protruding blade will be provided on the punching die, so that after the die is matched, punching is performed at the corresponding position on the surface of the workpiece inside the die.

[0004] During the punching process of existing punching dies, the pressure generated by the die during punching can cause the workpiece to stick to the die. After the punching is completed and the dies are separated from each other, workers need to manually remove the workpiece from the die. Faced with workpieces that are too tightly adhered, workers also need to use other tools to remove the material, which is time-consuming and labor-intensive to remove the workpiece after punching.

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0029] Example 1

The ejection component 7 includes an air pipe 702 inserted into the interior of the lower template 3, and four connecting rods 703 are fixedly connected to the inner wall of the air pipe 702. One end of the connecting rod 703 is fixedly connected to a lifting column 705, and the outer surface of the lifting column 705 is fixedly connected to four pushing blocks 704. The outer surface of the pushing block 704 abuts against the ejection block 701, and the outer surface of the ejection block 701 is movably connected to the outer surface of the lower template 3. The bottom end of the lifting column 705 is fixedly connected to a tension spring 706, and the bottom end of the tension spring 706 is fixedly connected to a cross bar 707. The two ends of the cross bar 707 are fixedly connected to the inner wall of the air pipe 702.

[0031] Specifically, the outer surface of the ejection block 701 is provided with a bevel, and the outer surfaces of the lower template 3 and the upper template 2 are provided with bevel grooves that cooperate with the ejection block 701. The ejection block 701 is provided with a bevel on the side close to the push block 704. A transverse slot is provided inside the ejection block 701. The upper surface of the cross bar 707 is fixedly connected to the limiting rod 709, and the top end of the limiting rod 709 is inserted into the sealing plate 708 and the lifting column 705.

[0032] Furthermore, compressed air is delivered through the air pipe 702, and the compressed air passes through the gap between the cross bar 707 and the air pipe 702, thereby pushing the sealing plate 708 upward, causing the sealing plate 708 to move upward. When the sealing plate 708 moves upward, it drives the lifting column 705 to move upward, and the lifting column 705 drives the four pushing blocks 704 to move, and the pushing blocks 704 drive the ejection block 701 to move, thereby driving the ejection block 701 to open. After the ejection block 701 is opened, the contact area of ​​the ejection can be increased, thereby avoiding damage to the workpiece caused by too small a contact area during ejection. After the ejection is completed, the delivery of compressed air is stopped, and the sealing plate 708 is reset under the drive of the tension spring 706, thereby driving the lifting column 705 and the pushing block 704 to reset. An air pump is externally connected to the end of the air pipe 702 away from the lifting column 705.

[0033] Example 2

[0034] Reference Figure 1 、 Figure 2 、 Figure 3 and Figure 6, which is the second embodiment of the present utility model, is based on the previous embodiment. The cleaning component 5 includes a threaded rod 508 movably connected to the outer surface of the lower template 3 through a bearing seat, the outer surface of the threaded rod 508 is threadedly connected to a threaded sleeve 505, the outer surface of the threaded sleeve 505 is fixedly connected to a slider 502, the upper surface of the slider 502 is fixedly connected to a connecting block 506, and the side of the connecting block 506 close to the lower template 3 is fixedly connected to two air jets 507, and a hose for connecting the air jets 507 is provided inside the connecting block 506.

[0035] Specifically, the outer surface of the template is fixedly connected to a connecting plate 504, the interior of the connecting plate 504 is movably connected to one end of the threaded rod 508 through a bearing, the outer surface of the connecting plate 504 is fixedly connected to a stepper motor 503, the output end of the stepper motor 503 is fixedly connected to one end of the threaded rod 508, the upper surface of the lower template 3 is fixedly connected to four limit columns 4, the interior of the upper template 2 is provided with a socket that cooperates with the limit columns 4, the interior of the upper template 2 and the lower template 3 are both provided with a cooling component 6, the outer surface of the lower template 3 is fixedly connected to a slide rail 501, the slide rail 501 is movably connected to the slider 502, and the movement directions of the two cleaning components 5 are set in opposite directions.

[0036] Furthermore, after punching and cutting, the upper template 2 and the lower template 3 are separated, and the stepper motor 503 is started to drive the threaded rod 508 to rotate, so that the threaded sleeve 505 drives the slider 502 to move on the slide rail 501, and drives the connecting block 506 to move during the movement. The connecting block 506 drives the air jet 507 to spray paint during the movement, thereby cleaning the punching debris remaining on the mold. The air jet 507 is connected to the external air pump through the hose provided inside the connecting block 506. The two cleaning components 5 are set in opposite directions to avoid the convection of the blown gas and reduce the cleaning effect. The connection relationship, working distance and operation process between the cooling component 6 and other components all belong to the existing technology and are common knowledge that technical personnel in this field should have, so they will not be elaborated here.

[0037] Working principle: When punching a sub-groove notch on a workpiece, place the workpiece on the lower mold and push the upper connecting seat 1 to drive the socket opened inside the upper mold to cooperate with the limit column 4 on the upper surface of the lower mold, thereby driving the upper mold and the lower mold to punch. After the punching is completed, pull out the upper connecting seat 1 to drive the upper mold to separate from the lower mold. After the separation process, compressed air is delivered through the air pipe 702. The compressed air passes through the gap between the cross bar 707 and the air pipe 702, thereby pushing the sealing plate 708 upward, causing the sealing plate 708 to move upward. When the sealing plate 708 moves upward, it drives the lifting column 705 to move upward. The lifting column 705 drives the four pushing blocks 704 to move, and the pushing blocks 704 drive the ejection block 701 to move, thereby driving the ejection block 701 to open, and finally realizing the ejection of the workpiece. After ejection, the worker takes out the workpiece and starts the stepper motor 503, thereby driving the threaded rod 508 to rotate, so that the threaded sleeve 505 drives the slider 502 to move on the slide rail 501, and in the process of movement, drives the connecting block 506 to move, and the connecting block 506 drives the air jet 507 to spray paint during the movement, thereby cleaning the punching debris remaining on the mold, and finally completing the punching process of the workpiece.
