Positional control bidirectional pressed moulding press

Abstract

The invention discloses a position control two-direction pressing moulding press, comprising a stander formed by the connection of a stander side plate, an upper beam and a lower beam; an upper cylinder fixed on the upper beam; a lower cylinder fixed on the lower beam; an upper die mounting plate installed on an upper die; a lower die mounting plate installed on a lower die; an upper cylinder displacement sensor fixed on the stander; and a lower cylinder displacement sensor fixed on the stander, wherein, the upper cylinder displacement sensor and / or the lower cylinder displacement sensor detect / detects the displacement of the upper cylinder and / or the lower cylinder, generating a displacement signal related to the displacement, and the displacement is processed by a displacement controller and then controls the oil supply state of an oil line of the upper cylinder / or the lower cylinder through a servo proportional valve. The moulding press can precisely press the production height according to production requirements, is characterized by convenient adjustment of the pressed product height and simple arrangement and can markedly improve the quality and dimensional uniformity of pressed products.

Description

technical field [0001] The invention relates to a magnetic powder molding press, in particular to a position-controlled two-way pressing molding machine. Background technique [0002] Patent application number 01226281.1, authorized announcement number CN 2483124Y, the Chinese invention patent "magnetic field powder molding press" published on March 27, 2002, such as figure 1 , the press is mainly composed of a frame, guide rails, movable beams and control cylinders. The press has three pressing methods. When using one-way pressing, the mold is clamped by the mold opening cylinder 21. After the magnetic powder is magnetized and oriented, the upper movable beam 2 and the upper mold 37 are driven by the upper oil cylinder 3 to compress the mold 38 downward. After demagnetization, the upper mold and the mold opening cylinder are reset, and the mold is taken out to complete a pressing process. When two-way pressing is adopted, the upper movable beam 2 and the upper mold 37 are...

AI Technical Summary

Problems solved by technology

The press needs to install and remove the mold for one-way pressing, which takes a long time and low efficiency; the operation is inconvenient

During two-way pressing and floating pressing, the height of the pressed product is completely controlled by the pressure of the oil cylinder. Due to the defects of the system oil circuit and the upper and lower oil cylinders, the pressure is unstable, and the height of the pressed product is different; the consistency of the workpiece is poor, which affects the quality of the product. Molding is also bad
