Description

Technical Field

[0001] The utility model relates to the field of machining, in particular to a single continuous blanking device. Background Art

[0002] Most of the existing metal forming processes use the method of blanking first and then taking out the sheet and sending it to the stretching forming process to complete the product forming. This method has low production efficiency. Some also use the method of integrated stamping and stretching. Although this method improves the production efficiency to a certain extent, such as the patent with publication number CN215587621U, the material still needs to be sorted after blanking, and then transported and rearranged before being sent to the next process. This is still not enough to meet the current rapid development needs. How to further improve production efficiency is an urgent problem to be solved. Summary of the invention

[0003] The utility model aims to provide a separate continuous blanking device which can synchronously complete the punching, stretching and feeding arrangement processes.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solution: a single continuous blanking device, which comprises: an upper die part and a lower die part,

[0005] The upper die portion includes an upper die seat, an upper die plate mounted on the upper die seat, and a plurality of upper punch assemblies mounted on the upper die plate;

[0006] The lower die portion comprises a lower die base, a lower die plate mounted on the lower die base, a lower movable plate mounted on the lower die plate and movable up and down, and a lower punch assembly passing through the lower movable plate and fixed on the lower die base;

[0007] The lower punch assembly is hollow, and a channel extending to the lower die seat is formed therein. The device includes a conveyor belt arranged below the lower die seat and used for conveying the stamped products falling from the channel.

[0008] In another embodiment, the upper punch assembly includes an upper stretching head fixed on the upper template, an upper punch ring mounted on the upper stretching head and movable in a vertical direction, and an upper telescopic member disposed between the upper punch ring and the upper template. When the upper punch assembly is pressed onto the material strip, the upper punch ring is squeezed and contracted, the upper telescopic member retracts, and the upper punch ring moves upward relative to the upper stretching head.

[0009] In another embodiment, the lower punch assembly includes a lower stretching cylinder fixed on the lower template, a lower stretching head fixed on the lower stretching cylinder, and a lower punch head fixed on the lower movable plate and sleeved on the lower stretching head. The lower punch head will move downward to the outer periphery of the lower stretching cylinder under the drive of the upper template.

[0010] In another embodiment, a stripping module for facilitating stripping is provided on the inner side wall of the lower stretching head, and the stripping module includes a stripping block which is provided on the inner circumferential surface of the lower stretching head and can move in a horizontal direction, and an elastic member which enables the stripping block to always have a tendency to move toward the axial center line direction of the lower stretching head, the upper end of the side surface of the stripping block smoothly transitions with the lower stretching head and has the same bending direction, and the lower end of the side surface of the stripping block forms a snap fit for being stuck on a product to allow the product to fall off the upper stretching head.

[0011] In another embodiment, the device includes a three-dimensional robot for driving the upper mold part, the lower mold part and the conveyor belt to move synchronously, and the three-dimensional robot drives the upper mold part, the lower mold part and the conveyor belt to move obliquely along the length direction of the material belt, so that the stamping holes in two adjacent rows on the material belt are staggered front and back.

[0012] The beneficial effects of the utility model are as follows: by utilizing the through lower punch assembly, the products can be directly and neatly arranged on the conveyor belt in order, thus saving the time of collecting products and then arranging and conveying them, and improving production efficiency; the upper die part, the lower die part and the conveyor belt are driven to move synchronously by the three-dimensional manipulator, so that the punching holes of two adjacent rows on the material belt are staggered front and back, making full use of the material belt and reducing material loss.

[0017] The utility model is further described below in conjunction with the accompanying drawings.

[0018] like Figure 1-3 As shown, the single continuous blanking device includes: an upper mold part 1, a lower mold part 2, a conveyor belt 3, and a three-dimensional robot 4 for driving the upper mold part 1, the lower mold part 2 and the conveyor belt 3 to move synchronously.

[0019] The upper die part 1 includes an upper die base 11, an upper die plate 12 installed on the upper die base 11, and multiple upper punch assemblies 13 installed on the upper die plate 12. The upper punch assembly 13 includes an upper stretching head 14 fixed on the upper die plate 12, an upper punch ring 15 sleeved on the upper stretching head 14 and movable in the vertical direction, and an upper telescopic member 16 arranged between the upper punch ring 15 and the upper die plate 12. When the upper punch assembly 13 is pressed on the material strip A, the upper punch ring 15 is squeezed and contracted, the upper telescopic member 16 retracts, and the upper punch ring 15 moves upward relative to the upper stretching head 14. The upper telescopic member 16 can be a cylinder.

[0020] The lower die part 2 includes a lower die base 21, a lower die plate 22 mounted on the lower die base 21, a lower movable plate 23 mounted on the lower die plate 22 and movable up and down, and a lower punch assembly 24 inserted through the lower movable plate 23 and fixed on the lower die base 21; the lower punch assembly 24 is hollow, and a channel 240 extending to the lower die base 21 is formed inside the lower punch assembly 24, and the device includes a conveyor belt 3 provided below the lower die base 21 and used to convey the stamped product B dropped from the channel 240. The lower punch assembly 24 includes a lower stretching cylinder 25 fixed on the lower die plate 22, a lower stretching head 26 fixed on the lower stretching cylinder 25, and a lower punch head 27 fixed on the lower movable plate 23 and sleeved on the lower stretching head 26.
