A forced reset device for the transverse punch of a stamping die

Abstract

The invention discloses a forced return device of a horizontal punch of a stamping die. The forced return device comprises a longitudinal wedge punch block (1), a horizontal punch block (2) and two slide groove blocks (3). A main punch oblique plane and a main oblique surface are arranged on the longitudinal wedge punch block. A guide hole is arranged in a sliding seat of the horizontal punch block, and an auxiliary punch oblique plane and an auxiliary oblique surface are arranged on the left side wall and the right side wall of the guide hole respectively. The longitudinal wedge punch block is located above the guide hole and connected with a slider of a punch press, the two slide groove blocks are slidably clamped on the front side face and the rear side face of the sliding seat and are slidably connected with slide rails in a fastening manner via slide grooves, and the slide groove blocks are both fixedly connected with a base of the die. The right end of the sliding seat is provided with a return pull rod and a spring. A punch of the horizontal punch block is located on the right of a female groove of the die. During return, the longitudinal wedge punch block returns upwards, the main oblique surface pushes the horizontal punch block via the auxiliary oblique surface to draw out the punch from a horizontal punched hole of a product forcibly and rightwards, the return pull rod and the spring assist in pulling the horizontal punch block to return, and accordingly the stamping die achieves the purposes of ensuring reliability, improving efficiency and lowering cost.

Description

technical field [0001] The invention relates to a stamping die, in particular to a forced reset device for the transverse punch of the stamping die used for resetting the transverse punch of the stamping die. Background technique [0002] Among the serial stamping dies of the step-by-step combined punching production line with materials, there are longitudinal stamping dies that punch the longitudinal structure of the product through the longitudinal punch, and there are also longitudinal punches that drive the horizontal punch to the horizontal structure of the product through the longitudinal wedge-shaped punch. Stamped transverse stamping dies, this paper relates to transverse stamping dies; [0003] After the stamping die is punched, the punch needs to be reset. The longitudinal punch of the longitudinal stamping die will reset upwards with the slide block of the punching machine, and the reset of the horizontal punch of the horizontal stamping die. The prior art uses a ...

Problems solved by technology

[0003] After the stamping die is punched, the punch needs to be reset. The longitudinal punch of the longitudinal stamping die will reset upwards with the slide block of the punching machine, and the reset of the horizontal punch of the horizontal stamping die. The prior art uses a strong spring to pull the horizontal punch from Pull out and reset from the punching hole of the horizontal structure of the product; because the spring is easy to fatigue, the reliability is poor, and the elastic force will decay over time, so that the horizontal punch cannot be reset, causing the entire joint punching production line to stop production due to jamming; the solution is to replace the new spring regularly, In this way, it is labor-intensive and time-consuming, which increases the maintenance cost of the mold and reduces the operating efficiency of the production line; therefore, the prior art has the problems and deficiencies of poor reliability, low efficiency, and high cost
