Description

Technical Field

[0001] This utility model relates to the field of punching die technology, specifically a high-speed punching die for battery connectors. Background Technology

[0002] A punching die is a mold used in the stamping process to punch holes in a workpiece. Its main function is to apply pressure to the material through a punch, causing the material to form the desired hole under the action of the die's concave or convex shape. In practical applications, punching dies are widely used in the automotive, home appliance, hardware, and electronics industries to process holes in various materials such as stainless steel, copper, and aluminum. The design of a punching die must consider not only the material properties but also stamping efficiency, positioning accuracy, and ease of operation.

[0003] A punching die, as disclosed in announcement number CN111438268A, comprises a fixed rod, a punch, spring plates, a support plate, and a wooden support mechanism. Four spring plates are fixed to the upper end of the support plate. The fixed rod is fixed around the punch. The wooden support mechanism is fixedly installed at the lower end of the support plate. The material is fixed in a placement groove, ensuring a sealed fit between the support block and the material. The punch then punches the material from the impact point. The pressure generated during the operation causes the material to exert pressure on the support block, subsequently entering a pressure-absorbing bag and inflating it. The expansion bag at the upper end of the airbag and the soft block at the upper end of the support block are compressed by the material. Due to its cushioning, softness, and adsorption properties, the strong vibrations of the punch operation are mitigated. The pressure block inside the blocking block provides further cushioning. The force on the pressure block acts on the pulley, which in turn exerts pressure on the elastic airbag, causing the pulley to slide on the outer wall of the punch, reducing the vibrations caused by the punch's impact.

[0004] The high-speed punching of the above-mentioned device may lead to the inability to punch for a long time, lack of protection, and fixed punching, resulting in a small working range. Therefore, we propose a high-speed punching mold for battery connectors to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to provide a high-speed punching mold for battery connectors, so as to solve the problems mentioned in the background art that existing high-speed punching may lead to the inability to punch for a long time, lack of protection, fixed punching, and small working range.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-speed punching die for a battery connector, comprising a fixed base, a guide groove provided in the fixed base, a second connecting base provided on the left side of the guide groove, a buffer device provided on the left side of the second connecting base, a first connecting base provided on the right side of the guide groove, a guide block provided at the lower end of both the first and second connecting bases, and both the first and second connecting bases being guided and connected to the guide groove through the guide block at their lower ends, an upper punching die provided in the first connecting base, a punching device provided at the rear end of the first connecting base, and a lower punching die provided in the second connecting base.

[0007] Preferably, both the first and second connecting seats are provided with sliding grooves, and both sides of the upper and lower punching dies are provided with sliding blocks. The upper and lower punching dies are slidably connected to the first and second connecting seats through the sliding grooves on both sides. Bolts are provided at the upper ends of both the upper and lower punching dies, and the upper and lower punching dies are bolted to the first and second connecting seats through bolts.

[0008] Preferably, the buffer device includes a buffer spring assembly, each buffer spring assembly including a spring and a damping rod, the rear end of the spring being mounted on a fixed base, and each spring containing a damping rod.

[0009] Preferably, the punching device includes a hydraulic cylinder and guide rods. The rear end of the hydraulic cylinder is disposed on the inner wall of the fixed seat, and the front end of the hydraulic cylinder is disposed at the rear end of the first connecting seat. Four sets of guide rods are evenly arranged in four groups on the hydraulic cylinder, and the rear ends of the four sets of guide rods all penetrate through and extend to the outside of the fixed seat.

[0010] Preferably, the lower punch mold has a punching groove at its front end, and there are multiple sets of punching grooves. Each set of punching grooves has a buffer perforation block, and each set of punching grooves has an oil outlet at its rear end. Each oil outlet has a filter block.

[0011] Preferably, an oil storage chamber is provided at the rear end of the oil outlet.

[0012] Preferably, the upper end of the punching die is provided with an oil inlet, an oil inlet pipe is provided inside the oil inlet, and the lower end of the oil inlet pipe is provided in the oil storage cavity.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) This utility model provides an oil outlet at the rear end of the punching groove in the punching lower die, and an oil storage chamber at the rear end of the oil outlet. The oil is sent to the punching groove through the oil outlet, which cools the punching head at the front end of the punching upper die during high-speed punching, thereby effectively extending the working time. In conjunction with the buffer device at the rear end of the punching lower die, it plays a buffering role during high-speed punching and protects the punching lower die, thus solving the problem that high-speed punching may lead to the inability to punch for a long time and lack of protection.

[0015] (2) The upper and lower punching dies are slidably connected to the first and second connecting seats through sliding grooves on both sides. The upper and lower punching dies are bolted together with the bolts set at the upper end, which makes it convenient to replace the upper and lower punching dies. The lower punching die has multiple sets of different punching grooves at the front end. Under different work requirements, only different upper punching dies need to be replaced, thus solving the problem of fixed punching and small working range. Attached Figure Description
