Abstract

The invention discloses a stamping die capable of improving the product precision, and belongs to the technical field of dies. The stamping die comprises an upper die and a lower die cooperated with the upper die, the lower die is provided with a locating pin with an adjustable diameter, the locating pin comprises a guide section, a locating section and a fixing section arranged from top to bottomin sequence, and the middle axes of the guide section, the locating section and the fixing section all coincide with one another, wherein the fixing section is fixedly connected to the lower die, theguide section and the fixing section are meshed on the single face through teeth to lock the guide section, and the locating section and the guide section are meshed on the two faces through teeth toadjust the diameter of the locating section. The stamping die has the main purpose of enabling the degree of freedom of parts both in the X direction and the Y direction to be zero, thus the locatingprecision of the parts is improved, then the product precision is improved, and using requirements of the product are met.

Description

technical field [0001] The invention belongs to the technical field of dies, and more specifically relates to a stamping die capable of improving product precision. Background technique [0002] With the rapid development of the home appliance industry, the precision requirements for home appliances are getting higher and higher. A large part of the parts on home appliances are realized by cold stamping dies, and the positioning accuracy directly affects the precision of stamping products. Therefore, for products The positioning requirements during the stamping process are particularly important. [0003] At present, in the actual stamping production process, positioning pins are basically used to position the plate, which plays the role of "centering" and "positioning". The degree of freedom in the direction is related to the processing accuracy of the locating pin, the pin hole of the part, and the mounting hole of the locating pin on the mold. There will be poor positio...
