Problems solved by technology

In the existing technology, in the stamping process of the thin plate, the upper mold and the lower mold are separated immediately after the stamping of the thin plate is completed, and there is no pressure holding stage. Due to the strain force in all directions during the stamping deformation process of the thin plate, plus the thickness of the thin plate Small, it will produce a certain deformation under the action of strain force, which seriously affects the quality of the product

Embodiment Construction

[0026] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0027] Firstly, a brief description will be given for the punching device involved in the present invention.

[0028] Such as Figures 1 to 6 As shown, the relevant stamping device involved in the present invention includes a driving mechanism, a movable die 101 and a bottom die 102, wherein the driving mechanism includes a fixed shaft 1, a hollow motor 2, a driving member 3, a rotating member 4, a connecting rod 45 and a limiter Cylinder 6.

[0029] Such as figure 2 As shown, the hollow motor 2 in the drive mechanism is connected to the drive member 3 through the fixed shaft 1, the rotating member 4 and the driving member 3 are respectively rotated on the fixed shaft 1, and the driving member 3 is provided with a hole for the installation of the rotating member 4. Installation space 301, rotating member 4 includes a turntable 401 and a tu...

Abstract

The invention discloses a stamping method. The stamping method is characterized by including the following steps that S1, a moving die is located at the furthest position away from a bottom die, and aworkpiece needing to be stamped is placed on the bottom die; S2, a hollow motor drives a driving part to continue to rotate by 180 degrees at a constant speed around a fixed shaft, a rotating part drives the moving die to move downwards, and the moving die and the bottom die are closed; S3, a limiting cylinder drives a limiting block to be inserted into a first limiting groove of the rotating part through an insertion strip, and at the same time, a transmission pin leaves a first transmission groove to realize pressure maintaining for the profile of the workpiece; S4, the transmission pin ona transmission block is inserted into a second transmission groove, the limiting block retracts into the fixed shaft, and the moving die gets away from the bottom die to realize discharging of the stamped workpiece; and S5, the steps from S1 to S4 are repeated to realize automatic continuous stamping of workpieces. According to the stamping method, the stamped workpiece can be shaped in the stamping process, and pressure maintaining cooling is performed to improve the stamping quality of the stamped workpiece.

Description

technical field [0001] The invention relates to the stamping field, in particular to a stamping method. Background technique [0002] In the stamping process of the thin plate, it is necessary to use the upper die and the lower die of the stamping equipment to stamp the plate into a specific shape, and then take out the stamped plate. In the existing technology, in the stamping process of the thin plate, the upper mold and the lower mold are separated immediately after the stamping of the thin plate is completed, and there is no pressure holding stage. Due to the strain force in all directions during the stamping deformation process of the thin plate, plus the thickness of the thin plate Small, it will produce a certain deformation under the action of strain force, which seriously affects the quality of the product. [0003] For example, the existing Chinese invention patent with publication number CN110421045A discloses a punching method, which includes the following steps...
