Hydraulic press with automatic weighing device and reciprocating work table

Abstract

The invention belongs to a hydraulic press and particularly relates to a press for powder compression molding forming. The press for powder compression molding forming consists of a hydraulic station taken as a power source, a control system and a main frame, wherein the main frame consists of a press and an automatic weighing device; and the press is formed according to the following mode: an upper beam (1), a lower beam (2) and a vertical column (3) are linked into a stress frame; an upper connecting plate (4), a movable cross-beam (5) and a pull rod (6) are linked into a closed frame which is fixedly connected with a piston rod of a potting oil cylinder (7) fixedly connected to an upper plane of the upper beam (1); the movable cross-beam (5) is guided through a guide sleeve (8) and can move up and down along the vertical column (3); an upper plane of the movable cross-beam (5) is fixedly provided with a guide rail (9); the guide rail (9) is provided with a reciprocating work table (10) which can move left and right along the guide rail; and a piston type master cylinder (13) fixedly connected with the lower beam (2) is arranged below the movable cross-beam (5). The press has the advantages of compact structure, automatic powder weighing, feeding and charging, and high automation degree of the whole machine.

Description

technical field [0001] The invention belongs to a hydraulic press, in particular to a powder molding press. Background technique [0002] In the past, hydraulic presses used for powder compression molding often only had a single pressing function, and the weighing of materials and feeding to the mold cavity were mostly done manually. Chinese patent application 2008200071225.6 (powder automatic weighing machine) can realize automatic weighing and transportation of materials , but it still needs to manually feed into the mold cavity, and the production site occupies a large area. [0003] In the past, the hydraulic press used for powder compression molding had only one station, and a set of molds was installed, and the loading, pressing, and ejection had to be carried out in time, and the auxiliary time was long and the work efficiency was low. In order to load the powder into the mold, the height of the opening has to be increased to leave enough space for the mold, so that ...
