Abstract
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 square hole spring cover of an intelligent anti-theft lock. 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 its working functions. The stamping die is divided into single-operation dies and continuous dies according to the forming process. Each set of single-operation dies forms one or two shapes, with low efficiency. A continuous die refers to completing the forming of the entire product 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. To meet the strong demand for household anti-theft locks, major latch manufacturers continuously expand the production output of latches. The increasing variety of anti-theft locks makes 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, and the metal stamping die is made according to the stamping process. The raw material is formed on the die to obtain the required metal structural parts. To improve production efficiency, major manufacturers have developed stamping continuous dies to increase production. However, due to the complexity of the latch parts, especially the structure of the square hole spring cover for intelligent anti-theft locks, the square hole spring cover for intelligent anti-theft locks cannot be produced on a set of continuous dies. Either it is still produced in the form of single-operation dies, consuming manpower and material resources, or it adopts a combination of partial continuous die forming and single-operation die forming, with low automation efficiency. Summary of the Utility Model
[0003] The purpose of the utility model is to address the above-mentioned defect that it is difficult to form the square hole spring cover for an intelligent anti-theft lock with a set of continuous dies, and provide a continuous stamping die for the square hole spring cover of an intelligent anti-theft lock, which can complete the forming of the entire product of the square hole spring cover for an intelligent anti-theft lock on a continuous die, and at the same time perform punching after forming to ensure the punching accuracy of the product, improve production efficiency, and the cost of the die is low.
