Frame type oleodynamic press for the crushing of titanium sponge knife

Abstract

The invention discloses a frame-type hydraulic press for sponge titanium jackknifing crush, belonging to the titanium alloy production facility. At present, the prior equipment applied for titanium lump crushing is the three-beam four-column jackknifing crush hydraulic press both at home and abroad, which has a plurality of drawbacks such as huge size, heavy weight, complex force condition of the components, bad rigidity of facility, high manufacturing cost and difficult maintenance. The invention is characterized in that: an upper beam, four frames and a lower beam of the hydraulic press form an enclosed force frame; four frames form an entirety; two cutting cylinders and one pressure cylinder are arranged on the upper beam; a plunger of the cutting cylinder is connected with a sliding block, the cutter connected on the sliding block, and the piston of the cylinder connected with the pressure rod, and a return cylinder and a push cylinder are arranged on the lower beam. The invention has the advantages of novel and simple structure, light weight, good rigidity, high precision, low manufacturing cost, long service life, easy maintenance and other advantages.

Description

technical field [0001] The invention relates to equipment for titanium alloy production, in particular to a hydraulic press for crushing sponge titanium lumps. Background technique [0002] In the production process of titanium alloy, titanium sponge particles are used as raw materials for production, which are broken from titanium sponge lumps. For the crushing of titanium sponge, the commonly used equipment at home and abroad is a three-beam four-column knife-cut hydraulic press. The main frame of this equipment is composed of an upper beam, a lower beam, a movable beam (slider), a guide frame, and a column. The guide frame 2 is fixed on four upright posts 1. The main disadvantage of this kind of equipment is: when the guide frame 2 is cutting the sponge titanium lump, the titanium lump will generate a large force perpendicular to the movement direction of the cutter. The cutter is connected to the slider, and the slider will guide the The force of the frame is very larg...

AI Technical Summary

Problems solved by technology

The main disadvantage of this kind of equipment is: when the guide frame 2 is cutting the sponge titanium lump, the titanium lump will generate a large force perpendicular to the movement direction of the cutter. The cutter is connected to the slider, and the slider will guide the The force of the frame is very large, which will generate a bending moment on the column

Due to the large bending deformation of the column, it is necessary to design a column with a large cross-sectional diameter to withstand the bending moment, resulting in a bulky column and high cost

At the same time, due to the large bending deformation of the column fixing the guide frame, the verticality of the oil cylinder is poor, causing leakage of the oil cylinder, and the service life of the guide sleeve and the seal is short
