A stamping die and its special-shaped punch switching device

Abstract

The invention discloses a stamping die and a special-shaped male die switching device thereof. The special-shaped male die switching device comprises an air cylinder fixed to an upper die seat, a sliding block is arranged at the telescopic end of the air cylinder, the sliding block blocks the end face of a special-shaped male die when the sliding block is located at the first limit position away from the fixed end of the air cylinder, and the sliding block avoids the end face of the special-shaped male die when the sliding block is located in the middle. A control panel rotatably arranged on the upper die seat is further included, and comprises a cross plate and a vertical plate, an acute angle is formed by the cross plate and the vertical plate, the end, away from the vertical plate, of the cross plate is fixed to the special-shaped male die, and the rotating center of the control panel is located at the crossing position of the cross plate and the vertical plate. A gap is formed in the sliding block, and when the sliding block is located in the middle, the vertical plate is clamped in the gap. The stroke of the sliding block in the telescopic direction is larger than the distance between the first limit position and the middle. Therefore, online switching of the special-shaped male die is achieved through the special-shaped male die switching device, and the work state and the non-work state of the special-shaped male die can be switched without shutting down a production line.

Description

technical field [0001] The invention relates to the technical field of dies, in particular to a special-shaped punch switching device for stamping dies. The present invention also relates to a stamping die comprising the above-mentioned special-shaped punch switching device. Background technique [0002] In order to meet the ever-changing market demand, it is often necessary to develop multiple models of the same series according to customer needs, functional configurations, etc., and among different models of the same series, the shape of the body panels is basically the same, and only part of the stamping parts. The local structure is different, such as adding holes to a stamped part to achieve functions such as installation. In this case, if the molds are developed separately for different models, the production cost will be increased. Therefore, in the actual production process, the special-shaped punch switching device is usually used to combine the above two different...

Problems solved by technology

[0005] However, when the above-mentioned special-shaped punch switching device performs switching production of two types of stamping parts, it is necessary to stop the production line, move the mold from the machine tool and open the mold, and then switch the working state of the special-shaped punch by manual operation; After the working state switching of the special-shaped punch is completed, the mold is closed and lifted to the machine tool and reinstalled, and then the stamping production of new parts is carried out; this results in a long switching time of the special-shaped punch, a large workload, and the operation of the switching process is relatively complicated. Complicated, low production efficiency, not conducive to automated production
