AI Technical Summary
The existing stamping machines produce huge impact on the base when stamping the workpiece, which can easily lead to damage to the base, reduce working efficiency and increase costs. At the same time, the versatility of the motor rotor stamping equipment is poor, and the rotor sheet is prone to misalignment during the stamping process, resulting in mold deformation and affecting the quality of the workpiece.
A motor rotor punching sheet manufacturing and processing mold is designed, including a fixed base, an upper mold, an assembled lower mold, a positioning column and a buffer rubber. The impact force is reduced by buffering rubber, and the positioning column and a limiting spring limit the mold position to avoid deviation and deformation.
By reducing impact force and limiting the position of the mold, it effectively prevents the deformation of the punch piece, improves the quality of the workpiece, reduces costs, and improves the versatility of stamping equipment.

Abstract
Description
Technical Field
[0001] The invention relates to the technical field of stamping dies, in particular to a manufacturing and processing die for a motor rotor punching sheet. Background Art
[0002] Stamping dies are special process equipment used to process materials (metal or non-metal) into workpieces (or semi-finished products) in cold stamping. Stamping is a pressure processing method that uses a die installed on a press to apply pressure to the material at room temperature to separate or plastically deform it, thereby obtaining the desired workpiece.
[0003] At present, when stamping workpieces, the stamping machines will generate huge impact force on the base, which can easily cause damage to the base, reduce work efficiency and increase cost investment. In addition, the motor rotor stamping equipment has poor versatility, and the rotor pieces are positioned multiple times. During the stamping process, misalignment is prone to occur, causing mold deformation, which will cause the rotor to deform and affect the quality of the workpiece. Summary of the invention
[0004] In order to solve the above-mentioned existing problems, the present invention provides a motor rotor punching manufacturing and processing die, which is used to solve the problem of deformation caused by errors during punching.
[0005] The technical solution adopted by the present invention is as follows:
[0006] The present invention discloses a motor rotor punching manufacturing and processing mold, comprising a fixed base, an upper mold, an assembled lower mold, a positioning column and a buffer rubber, wherein the buffer rubber, the upper mold, the assembled lower mold and the fixed base are connected in sequence from top to bottom, the positioning column is connected and arranged between the upper mold and the assembled lower mold, a rotor punching upper pressing block is extended downward at the bottom center of the upper mold, a rotor punching lower pressing groove is recessed downward at the top center of the assembled lower mold, the rotor punching upper pressing block is matched with the rotor punching lower pressing groove, and the rotor punching upper pressing block is buckled in the rotor punching lower pressing groove.
[0007] Furthermore, a mounting groove is provided on one side of the assembled lower mold, and a mounting protrusion is provided on the other side of the assembled lower mold, and the mounting protrusion is adapted to the mounting groove, and the positioning column is vertically connected to the fixed base, and the side ends of the upper mold and the assembled lower mold are connected with positioning parts, and the positioning parts of the upper mold and the assembled lower mold are sleeved on the outside of the positioning column, and the upper mold and the assembled lower mold slide up and down along the positioning column, and a limit part is provided on the top of the positioning column, and a limit spring is provided between the limit part and the positioning part of the upper mold, and the limit spring is sleeved on the outside of the positioning column.
[0008] Furthermore, a positioning cone is provided at the bottom of the upper mold extending downward, and a cone groove is provided at the top of the assembled lower mold in a concave shape downward, and the positioning cone is inserted in the cone groove.
[0009] Furthermore, a buffer spring is provided between the bottom of the assembled lower mold and the fixed base.
[0010] This scheme is a motor rotor punching manufacturing and processing mold, and the beneficial effects achieved by the present invention using the above structure are as follows:
[0011] 1. Multiple molds can be assembled together by installing the mounting protrusions on the side of the assembled lower mold in conjunction with the mounting grooves. Then, the upper mold can be impacted by a punching machine. The impact force of the punching machine on the upper mold can be weakened by the buffer rubber, thereby protecting the upper mold and preventing the punching sheet from deformation.
[0012] 2. The metal is molded by the cooperation between the upper mold and the assembled lower mold. The position of the upper mold and the lower mold can be restricted by the installation of the positioning cone and the cone groove to avoid deviation between the upper mold and the assembled lower mold. The limit spring and the buffer spring can buffer the overall work and further prevent the problems of deviation and deformation. BRIEF DESCRIPTION OF THE DRAWINGS
