Description

Technical Field

[0001] The utility model relates to the technical field of oil pressure punching devices, in particular to an oil pressure punching module. Background Art

[0002] exist

[0003] Punching operation is a commonly used processing method in mechanical processing. The existing hydraulic punching equipment is relatively small in design and simple in structure. The tool setting, feeding, positioning and punching switch are all manually operated with a low degree of automation. When changing the type of punching, the entire equipment needs to be replaced. The overall process is numerous, and continuous punching operation cannot be achieved well, and production efficiency cannot be guaranteed. Utility Model Content

[0004] In order to overcome the above disadvantages, the purpose of the present invention is to provide a hydraulic punching module to solve the problems caused by the above background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is a hydraulic punching die set, comprising a plurality of punching units and a plurality of lower templates, wherein: the plurality of punching units are arranged at intervals along a first direction and a second direction. Each of the punching units can operate independently. The plurality of lower templates are arranged below the plurality of punching units along a third direction, and are arranged one by one in position corresponding to the plurality of punching units, for placing products to be punched, and the first direction, the second direction and the third direction are perpendicular to each other.

[0006] Each of the punching units includes a hydraulic cylinder, a telescopic rod and an elastic pressing assembly. The hydraulic cylinder, the telescopic rod and the elastic pressing assembly are arranged in sequence along the third direction. The elastic pressing assembly is arranged above the lower template. The telescopic rod extends along the third direction, and one end is connected to the hydraulic cylinder, which is used to drive the telescopic rod to extend through the hydraulic cylinder, contact and press the elastic pressing assembly downward until the bottom of the elastic pressing assembly is pressed against the lower template to complete the punching of the product to be punched.

[0007] The hydraulic punching module provided by the utility model includes a plurality of punching units, each of which can be provided with punchings of different sizes and types, so as to realize the completion of multiple punching operations at the same time and improve the overall punching efficiency. In addition, each punching unit can work independently, and the working method is more diversified and adapted to production needs. The product to be punched is punched by the indirect driving of the elastic top-pressing component by the hydraulic cylinder and the telescopic rod. If the telescopic rod is directly connected to the component used for top-pressing, the extension distance of the telescopic rod will be extended, and the telescopic rod may produce a deflection angle and instability, resulting in a large error in the punching precision.

[0008] In some embodiments, the oil pressure punching module further comprises an upper stripping plate. The upper stripping plate extends along the first direction, and a plurality of the elastic pressing components are disposed through the upper stripping plate.

[0009] In some embodiments, the elastic pressing assembly includes a punching die column and a fixed sleeve. The punching die column extends along the third direction, and its two ends are respectively used for crimping with the telescopic rod and the lower template. The fixed sleeve extends along the third direction and is sleeved on the fixed sleeve. The fixed sleeve includes a fixing portion and a limiting portion along the third direction. The limiting portion and the punching die column are both penetrated through the upper stripping plate. The fixing portion is provided at the top of the upper stripping plate, and its radius is greater than the radius of the limiting portion, and is used to abut against the upper stripping plate for limiting.

[0010] With the above technical solution, the punching die column in the elastic top pressing assembly is used to contact the telescopic rod and the lower template. The fixed sleeve is divided into upper and lower parts, both of which are sleeved on the punching die column. The fixed part of the upper part is a larger fixed part, which abuts against the upper release plate to limit the position.

[0011] In some embodiments, the inner wall of the limiting portion is provided with a limiting block extending along the first direction, and the side wall of the punching die column is provided with a waist-shaped groove corresponding to the position of the limiting block. The waist-shaped groove is open at the bottom and closed at the top, and is used to limit the downward movement of the punching die column.

[0012] By adopting the above technical solution, the limiting part of the lower part is limited by the limiting block arranged on the inner wall and the sliding cooperation with the waist-shaped groove. The bottom of the waist-shaped groove is open, and when the punching die column moves upward, it will directly slide out of the waist-shaped groove. The top of the waist-shaped groove is closed, and when the punching die column moves downward, it will abut against the top of the waist-shaped groove, thereby completing the limiting.

[0013] In some embodiments, the fixing portion includes a plurality of mounting holes and a plurality of springs. The plurality of mounting holes are arranged around the fixing portion, and the plurality of springs are arranged in the plurality of mounting holes respectively. The punching die column is provided with abutment portions corresponding to the positions of the plurality of springs.

[0014] By adopting the above technical solution, when the punching die column moves downward, its abutment part will press down the multiple springs in the fixed part. When the punching operation is completed, the telescopic rod retracts and no longer presses the punching die column. When the compressed multiple springs are reset, the abutment part is lifted, so that the punching die column can be reset for the next punching operation.

[0015] In some embodiments, the hydraulic punching die set further comprises an upper die seat. A plurality of the hydraulic cylinders are disposed on the top of the upper die seat, a plurality of the telescopic rods are passed through the upper die seat. A connecting frame is disposed on the top of the upper die seat.

[0017] In some embodiments, the hydraulic punching die set further comprises a lower die base. The plurality of lower die plates are disposed on the top of the lower die base.

[0018] In some embodiments, an upper pad is provided at the bottom of the upper stripping plate.

[0019] By adopting the above technical solution, an upper pad is provided to protect the upper supporting plate, and the punching die column and the limiting part are penetrated through the upper pad.

[0020] In some embodiments, the hydraulic punching die set further comprises a plurality of protective plates, which are arranged between the upper die base and the upper stripping plate and on both sides of the plurality of punching units along the first direction and the second direction for closed protection.

[0021] By adopting the above technical solution, a plurality of protective plates surround a plurality of stamping units to provide closed protection.

[0022] In some embodiments, the hydraulic punching die set further comprises a plurality of sliders, which are respectively arranged on two sides of the bottom of the lower die base along the second direction and on two sides of the top of the upper stripping plate along the second direction.
