Problems solved by technology

In this type of equipment, after repeated cutting operations, the knife edge is prone to wear and setbacks, resulting in poor punching effect, so it is necessary to replace the knife edge plate in time according to the processing conditions
The existing knife-edge plate is generally directly fixed on the lower mold base by screws, which will waste a lot of time during disassembly and assembly, resulting in reduced processing efficiency and unable to meet production requirements

Embodiment 1

[0027] This embodiment proposes a quick-detachable combination mechanism for the lower die base of the punching machine, combining Figure 1 to Figure 4 As shown, it includes a lower mold base body 100, a lower mold push block 101 and a lower mold knife edge plate 102, the top of the lower mold base body 100 is provided with a lower mold chute 103, and the lower mold push block 101 is located at In the lower mold chute 103, and the lower mold push block 101 can slide relative to the lower mold chute 103, and the top of the lower mold base 100 is fixed with two lower mold stoppers 104, two The lower mold limiting plate 104 is separately arranged on both sides of the lower mold chute 103, and the two sides of the lower mold pushing block 101 are respectively provided with push block slots 105, and the edges of the two lower mold limiting plates 104 are respectively engaged. Set in the push block slot 105, the lower mold knife edge plate 102 is fixed on the top of the lower mold ...

Embodiment 2

[0037]In practical applications, in order to ensure the accuracy of the punching position, the graphic target point is generally pre-printed on the PCB board, and the camera is installed on the die base of the punching machine at the same time, and the punching position of the punching needle is determined by the position of the graphic target point collected by the camera. . However, due to the expansion and contraction of the PCB board under different environmental conditions, and its expansion and contraction coefficient cannot be determined, the punching needle cannot be accurately translated to the target position, thereby affecting the accuracy of the punching position, thereby reducing the processing of the PCB board yield.

[0038] In this regard, this embodiment proposes a lower mold with an optical reference target, which helps the control system to calculate the expansion and contraction coefficient of the PCB board, and helps to accurately control the punching posi...

Embodiment 3

[0045] In practical applications, in order to ensure the accuracy of the punching process, the control system needs to monitor and collect images on the surface of the PCB board. The existing technical means generally use a vertically installed camera to capture the surface image of the PCB board, but this vertical A vertically installed camera will occupy a certain amount of vertical space, and it is not convenient to install on the upper die base of the punching machine, so it is difficult to meet the assembly requirements of the equipment.

[0046] In this regard, this embodiment proposes a 90-degree image acquisition mechanism for an alignment camera that can be horizontally fixed on the bottom of the upper die base and helps save the vertical space of the punching machine. Figure 7 to Figure 10 As shown, it includes an upper mold base 130 and a lower mold base 100, the lower mold base 100 is located below the upper mold base 130, and the lower mold base 100 is provided wi...

Abstract

The invention discloses a quick-release combination mechanism of a lower die holder of a punching machine. The quick-release combination mechanism comprises a lower die holder body, a lower die push block and a lower die knife edge plate, a lower die sliding groove is formed in the top of the lower die holder body, two lower die limiting plates are fixed at the top of the lower die holder body, push block clamping grooves are respectively formed in two sides of the lower die push block, the edges of the two lower die limiting plates are clamped in the push block clamping grooves correspondingly, the lower die knife edge plate is fixed to the top of the lower die push block, a vertical hole is formed in the bottom of the lower die sliding groove, a lateral opening is formed between the vertical hole and the end face of the lower die holder body, a radial insertion hole is formed in the side of a lifting ejector block, a pull rod is inserted into the radial insertion hole, a stopping piece used for bearing the pull rod is arranged at the end part of the lower side holder body, a push block bolt is formed at the top end of the lifting ejector block, and the push block bolt is inserted into the lower die push block from the bottom and is in sliding fit with the lower die push block. The knife edge plate can be quickly disassembled and replaced, the knife changing time is saved, and the machining efficiency is further effectively improved.

Description

technical field [0001] The invention relates to a punching machine, in particular to a quick-detachable combination mechanism for a lower mold base of a punching machine. Background technique [0002] In the process of PCB board processing, punching processing is usually involved. In the existing PCB board punching equipment, the punching processing is generally realized through the mutual cooperation of the punching needle and the knife edge. In this type of equipment, after repeated cutting operations, the knife edge is prone to wear and setback, resulting in poor punching effect. Therefore, it is necessary to replace the knife edge plate in time according to the processing status. The existing knife-edge plate is generally directly fixed on the lower mold base by screws, which will waste a lot of time during disassembly and assembly, resulting in reduced processing efficiency and unable to meet production requirements. Contents of the invention [0003] The technical p...
