Description

Technical Field

[0001] The utility model belongs to the technical field of intelligent anti-theft lock forming, and specifically relates to a continuous stamping die for a sleeve plate. Background Art

[0002] The stamping of parts is completed by the relative movement of the upper and lower dies of the stamping die. The entire stamping die is divided into working parts, positioning parts, blank-holding, unloading and discharging parts, guiding parts, supporting and clamping parts, and fastening parts according to the working functions. The stamping die is divided into single-operation dies and progressive dies according to the forming process. Each set of single-operation dies forms one or two shapes, with low efficiency. A progressive die means that the entire product is formed through a set of dies. Since many parts of household anti-theft locks are metal parts, stamping dies are widely used in the household anti-theft lock industry. In order to meet the strong demand for household anti-theft locks, major latch manufacturers continuously expand the production output of latches. The increasingly numerous anti-theft locks make the production of latch spare parts increasingly require automation. Traditionally, for various metal structural parts, the stamping process is generally prepared according to the material characteristics and shape characteristics of the metal structural parts and the requirements of material forming. The metal stamping die is made according to the stamping process, and the raw material is formed on the die to obtain the required metal structural parts. In order to improve production efficiency, major manufacturers have developed progressive stamping dies to increase production. However, due to the complexity of the sleeve plate structure, the sleeve plate cannot be produced on a set of progressive dies. Either the single-operation die form is still used for production, which consumes manpower and material resources, or the partial progressive die forming plus single-operation die forming method is adopted, and the automation efficiency is not high. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a continuous stamping die for a sleeve plate aiming at the defect that the existing sleeve plate is difficult to be formed by a set of progressive dies, which can complete the forming of the entire sleeve plate product on the progressive die, improve the production efficiency, and the cost of the die is low.
