Abstract

The invention provides a locking pump for fast punch sliding-block oil cylinder locking. The locking pump comprises a locking pump shell, a first piston, an unloading one-way valve, an oil returning opening, a cylinder cover, an oil outlet, an oil suction and an air pump, wherein the first piston is arranged on the left end side of the locking pump shell, the unloading one-way valve is installed on the right side of the first piston, the oil returning opening is formed in the bottom of the locking pump shell, and the oil returning opening communicates with the unloading one-way valve; the cylinder cover is installed on the left end side of the locking pump shell and wraps the first piston, an unloading air supply opening is formed in the middle of the cylinder cover and communicates with the first piston, the oil outlet is formed in the middle of the front side of the locking pump shell, and a discharge one-way valve is arranged at the oil outlet; and the oil suction is formed in the bottom of the locking pump shell, a suction one-way valve is installed at the oil suction, and the air pump is installed on the right side of the locking pump shell. According to the locking pump for fast punch sliding-block oil cylinder locking, it can be guaranteed that the locking pump cannot be influenced by the change of oil pressure in a sliding block oil cylinder, and the stability of the oil cylinder pressure can be better maintained.

Description

technical field [0001] The invention relates to a locking pump, in particular to a locking pump used for fast punching press slider oil cylinder locking. Background technique [0002] A punch press is a stamping press. In national production, the stamping process has the advantages of saving materials and energy, high efficiency, low technical requirements for operators, and the ability to produce products that cannot be achieved by mechanical processing through various mold applications. It is used more and more widely. [0003] Stamping production is mainly for plates. Through the mold, blanking, punching, forming, deep drawing, trimming, fine blanking, shaping, riveting and extrusion parts can be made, which are widely used in various fields. For example, we use switch sockets, cups, cupboards, dishes, computer cases, and even missile aircraft. There are many accessories that can be produced by punching through molds. [0004] The design principle of the punching mach...
