Description

TECHNICAL FIELD

[0001] The application relates to the stamping technology field, in particular to a high-safety stamping device. BACKGROUND

[0002] With the development of modern manufacturing industry, mass production has become an important demand of the manufacturing industry. Stamping processing can quickly produce a large number of parts with complex shapes and high dimensional accuracy due to its high efficiency and high precision. Through stamping processing, batch production can be realized, production efficiency can be improved, and production cost can be reduced.

[0003] In the traditional stamping operation scene, safety protection mainly relies on the protective frame arranged on the stamping die. Photoelectric sensors are installed on both sides of the protective frame. During the operation of the stamping machine, if the photoelectric sensor detects that the worker is close to the stamping die, the stamping machine will be automatically controlled to stop working, so as to protect the safety of the personnel.

[0004] After completing a stamping operation, the worker needs to take out the stamped product. However, there may be a situation of accidentally touching the start switch, which not only hinders the worker from taking out the product from the stamping die, but also may cause damage to the equipment, and even cause serious injury to the on-site personnel, which needs to be improved.
