Embodiment Construction

[0020] 2. The lower mold body 1 is made of the following mold steel materials:

[0021] a. Steps of pouring mold steel billet

[0022] The weight percentage of each chemical component in the mold steel billet is: carbon 0.26-0.36%, manganese 1.05-1.50%, silicon 0.35-0.60%, phosphorus 0.014-0.034%, sulfur 0.012-0.036%, chromium 0.450-0.65%, molybdenum 0.003-0.006%, nickel 0.001-0.025%, vanadium 0.005-0.015%, copper 0.008-0.025%, nitrogen 0.002-0.005%, the matrix is ​​iron; the temperature of the cast mold steel is lowered to 250 ℃, and the following treatment is repeated three times: Reheat to 650-760°C, hold for 5-6 hours, cool to 280-320°C, hold for 3-5 hours, then heat to 650-690°C, hold for 3-4 hours, cool to 500 at 40°C / hour ℃, and then cooled to 120℃ at 21℃ / hour;

[0023] b. Heat treatment step

[0024] For the mold steel obtained in step a, reheat to 980°C and keep it warm for 1-2 hours, oil-cool it to no higher than 100°C, reheat it to the temperature range of 680°C-...

Abstract

The invention discloses an automatic stamping lower die structure for a filter screw plate. The stamping lower die structure comprises a lower die body. The lower die body is provided with a die cavity in the middle, and positioning holes are distributed on the lower die body outside the die cavity. The stamping lower die structure is characterized in that the die cavity is provided with a three-stage step which is matched with a step surface of a filter screw plate to be formed, air outlets are distributed in the die cavity, and air intake pipelines of the air outlets are located in the lower die body below the die cavity. The automatic stamping lower die structure of the filter screw plate is reasonable in structural design, can be punching forming at one time and is convenient for material taking, small in manual labor intensity, timesaving and laborsaving, and work efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of die processing, in particular to a lower die structure for automatic stamping of a filter screw plate. Background technique [0002] The filter screw is made by extrusion through a die. The so-called mold is a tool used to shape objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the article through the change of the physical state of the formed material. [0003] In the filter screw plate forming mold, the existing lower mold has a simple structural design. After stamping and forming, it is troublesome, time-consuming and labor-intensive to take out the material, and the work efficiency is low, which cannot meet the use requirements. Contents of the invention [0004] The purpose of the present invention is to make up for the deficiencies of the prior art, and to provide an automatic stamping lower die...
