Abstract

The invention discloses a shearing and blanking die. The shearing and blanking die comprises an upper die and a lower die, wherein the upper die is arranged above the lower die. The shearing and blanking die is characterized in that the upper die mainly comprises a male die (3) connected with the lower end of a fixing plate (2); an upper die holder (1) is arranged at the upper part of the fixing plate (2); the lower die comprises a female die (5), a positioning plate (4) and a lower die plate (6); the female die (5) and the positioning plate (4) are arranged on the lower die plate (6); a mounting clearance is formed between the female die (5) and the positioning plate (4); the female die (5) is positioned below the male die (3); the female die (3) is a right trapezoid cutter; the positioning plate (4) and the female die (5) are arranged in parallel; and both the female die (5) and the male die (3) are made of cold work die steel. The shearing and blanking die disclosed by the invention has the advantages of accuracy, high efficiency, simple structure, convenience in operation, economy, durability, and suitability for popularization and application of shearing strip sheet materials such as sealing ropes.

Description

technical field [0001] The invention belongs to the technical field of shearing devices, and in particular relates to a shearing blanking die. Background technique [0002] Sealing ropes are widely used in engines used in airplanes, ships, automobiles, electric machinery, and mining machinery. In the production process of the sealing rope, the first thing to be carried out is the blanking process of the material body. In the prior art, it is impossible to meet the corresponding high-precision requirements for the cutting of thin and long sealing ropes exceeding 600mm, and the shearing mold has complex structure, inconvenient operation, low efficiency, high cost and short service life. It has been unable to meet the blanking requirements of thin and long sealing ropes. Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned shortcomings and provide a shearing and blanking die that is accurate, efficient, simple in structur...
