Abstract
The utility model provides a gentle cold extrusion hydraulic machine having a double extrusion function, which is characterized in that: an ejecting cylinder and an ejector rod are arranged in a lower crossbeam; an upper cross beam and a slider are provided with master cylinders and two side cylinders; the cylinder body of the master cylinder is arranged on the slider; the piston of the master cylinder is fixed on the upper cross beam; the bottom part of the slider is also processed with a quadric extrusion oil cylinder coaxial with the master cylinder body and the piston of the quadric extrusion oil cylinder; the gentle cold extrusion hydraulic machnie having a double extrusion function solves the problem of the linkage procedures of the stretching procedure and the extruding procedure of the work piece, reduces the work piece processing procedure, not only reduces the work piece processing cost but also improves the work piece precision; in addition, the gentle cold extrusion hydraulic machnie having a double extrusion function also has the advantages of compact structure and easy production.
Description
Technical field
The utility model relates to a kind of forging machinery and equipment, especially a kind of warm cold extrusion hydraulic press with two squeeze function.
Background technology
Hydraulic press is usually used in stretching, the processing and forming of workpiece.Its structure mainly is the framework that upper and lower crossbeam and two columns constitute, and slide block that moves up and down and master cylinder and two side cylinders that drive slide block movement thereof are installed in the framework.This hydraulic press action is single, process a workpiece and often pass through several operations, pretty troublesome, as the bottom that processes a tubular has centre bore, and (or the workpiece of counterbore needs to stretch, two operations of punching (or extruding), therefore need two molds, the concentricity of not only processing cost height, and centre bore and tube is also poor.
Summary of the invention
The utility model provides a kind of warm cold extrusion hydraulic press with two squeeze function for solving the technical problem that exists in the known technology.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of warm cold extrusion hydraulic press with two squeeze function, by entablature and sill, be installed in column and fastening pull rod and nut that between entablature and the sill two have guide rail, be installed in the slide block that moves up and down between two column guide rails, the master cylinder that drives slide block movement and both sides cylinder and the liftout tank that is installed in the sill is formed, be shaped on the cylinder body of master cylinder on the described slide block, the piston of master cylinder is installed on the described entablature, also be shaped on coaxial secondary extrusion oil cylinder in the lower end of slide block, in the secondary extrusion oil cylinder piston be installed.
Advantage and the good effect that the utlity model has are: owing to install a coaxial secondary extrusion oil cylinder and a piston thereof additional in slide block cylinder body lower end, make hydraulic press have squeeze function twice, significantly reduce workpiece manufacturing procedure and number of molds, therefore not only reduce the processing cost of workpiece but also the precision of raising workpiece; The utility model also has compact conformation in addition, the advantage that is easy to make.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1, the hydraulic press framework that constitutes by entablature 6, sill 15, two pillars 11 and pull bar 1 and nut 2.In sill, liftout tank 17 and push rod 16 thereof are installed by locknut 18.Fixed guide 10 all is installed on two pillars, the slide block 9 that moves up and down is installed between guide rail, also be equipped with on slide block and adjust guide rail 12, the last plane of the lower plane of slide block and sill all is equipped with the backing plate 14 of the mould that is installed.Master cylinder 4 and the both sides cylinder 3 that drives slide block movement is installed on slide block and entablature.The both sides cylinder is installed on the entablature by locknut 5, and both sides cylinder piston end is installed on the slide block by flange 8.The cylinder body of master cylinder is formed in the slide block, is a slide block structure part, and the piston 7 of master cylinder is installed on the entablature, can shorten the distance between master cylinder and both sides cylinder like this, make structure compact more, reduce cost.For hydraulic press has the secondary extrusion function, the slider bottom in the master cylinder body lower end also is shaped on the secondary extrusion oil cylinder coaxial with master cylinder body, and the secondary extrusion oil cylinder also is a slide block structure part, and the piston 13 that can move up and down is installed in its oil cylinder.
Operating principle:
Master cylinder 4 and both sides cylinder 3 input pressures oil drive slide block down, stretch, and after stretching stopped, secondary extrusion oil cylinder input pressure oil driven plunger 13 was descending, carries out the secondary extrusion moulding, then master cylinder and both sides cylinder, the backhaul successively of secondary extrusion oil cylinder.
Claims (1)
