The identification of the cutting press machine is as follows:
1, the body, the general renovation cutting machine must use the body, carefully look at the paint appearance, the use of the workbench, under the machine and so on.
2, the oil pump, which belongs to the main components of the machine, the price is relatively high, generally will not be changed, please carefully check.
3, the solenoid valve, which also belongs to the main components of the refurbished cutting machine machine, the price is relatively high, generally will not be changed, please carefully check.
4, the oil cylinder, which also belongs to the main components of the machine, the price is relatively high, generally will not be changed, please carefully check.
5, the motor, generally will not be changed, need to repaint, please open the cover of the motor behind the renovated cutting machine carefully check.
What are the blanks of the cutting press machine?
Cutting machine blank manufacturing is a part of the parts production process, is the first step from raw materials to finished products. The material of the blank is determined by the structure, size, use and above conditions of the parts. The type of the blank mainly depends on the material, shape and production nature of the wool cup.
The commonly used rough product roughly has the following several kinds.
1. Casting piece blank:
Complex shape and strength of wood. The material of the cast may be cast iron, cast steel, or syntinated metal. According to the yield and precision requirements of the parts, the same casting method can be used.
2. Forgings blank:
Strength requirements of the very well forged parts of the most appropriate blank. The main materials are various kinds of carbon steel and alloy steel. Manufacturing methods: white out forging, tire die forging, die forging and precision die forging, etc. In the production of large personnel, die forging is generally used, the precision and production of such forging: very high rate; free forging for single and small batch production; in medium batch production, some can be used and some can be used.
3. Rolling material blank:
The cutting blank includes a variety of cold pull and hot rolled materials, which are circular, hexagonal, square and various boundary sections. All kinds of section rods used in the automatic lathe are cold her steel.
4. Bad hair of extrusion parts:
Used for certain non-ferrous metals and sodium materials with better plastic deformation. Cold extrusion (including cold firing) is widely used to squeezing bolts, nuts, pins, etc. Cold extrusion (or hot extrusion) is used for some gear type and complete cover type parts, suitable for large quantities and mass production.
