Abstract

The utility model provides a hydraulic pressure size reducing machine, includes the frame, and the frame middle part is equipped with the crossbeam, and the cylinder body of hydraulic pressure jar is fixed to the upper end of frame, and its piston downwardly extending, crossbeam correspond the position at the piston and are equipped with the mould, and the axial of mould is equipped with well kenozooecium, and the internal diameter of well kenozooecium entry end is greater than the other end, taper transition between the both ends, the control part of pneumatic cylinder is established in the frame. Compared with the prior art, the beneficial effects of the utility model are that: through the effect control of pneumatic cylinder control part, the piston can accurately effectual act on the work piece to and the size of kenozooecium is standard in the mould, can fix the work piece, guarantees the machining precision of work piece greatly, and the undergauge of work piece produces tensile deformation through the physics extrusion and accomplishes, does not have the waste material to produce.

Description

Hydraulic aperture reducing machine
Technical field
This utility model belongs to screw rod manufacture field, and in particular to a kind of hydraulic aperture reducing machine.
Background technology
Screw rod as plant equipment conventional parts, purposes widely, especially in some special installations, to screw rod Requirement is also differed, such as specific part will use diameter progressive screw on track for a train(It is carved with screw thread in thinner one end)Could expire Sufficient technical need.The predominantly organic bed processing of traditional screw rod manufacture method and casting forging etc..During machine tooling, by milling Change diameter of work, many waste materials can be produced, working (machining) efficiency is low;Casting forging needs to be carried out under hot conditionss, bad environments, and size Precision is low, and quality is difficult to ensure.
Utility model content
The purpose of this utility model is to provide a kind of saving material, hydraulic aperture reducing machine high in machining efficiency.
The technical solution of the utility model is specially:
A kind of hydraulic aperture reducing machine, including frame 1, the middle part of frame 1 is provided with crossbeam 12, the fixative cylinder pressure of top 11 of frame 1 Cylinder body 21, its piston 22 extends downwardly, and crossbeam 12 is provided with mould 4 in the correspondence position of piston 22, and being axially arranged with for mould 4 is hollow Portion 41, the internal diameter of the arrival end of hollow bulb 41 is more than the other end, and taper transition between two ends, the control unit of hydraulic cylinder is located at frame 1 On.
Piston 22 fixes top board 31, and top board 31 is provided with pull bar 32, and pull bar 32 extends downward the lower end of crossbeam 12 with Top board 33 is connected;Hollow bulb 41 extends downward the lower surface of crossbeam 12, and in the hollow bulb 41 push rod 34 is provided with, push rod 34 Lower end is fixed on lower roof plate 33.
Top board 31 and/or lower roof plate 33 are fixed disk.
Pull bar 32 is connecting rod, and it is provided with two, is symmetrically arranged at the both sides of piston 22.
Compared to the prior art, the beneficial effects of the utility model are:Controlled by the effect of hydraulic cylinder control unit, piston Workpiece, and the dimensional standard of mould hollow bulb can be accurately and effectively acted on, workpiece can be fixed, be ensured significantly The machining accuracy of workpiece, the undergauge of workpiece produces tensile deformation to complete by physical impact, produces without waste material.
Description of the drawings
Fig. 1 is this utility model schematic diagram.
Specific embodiment
As shown in figure 1, a kind of hydraulic aperture reducing machine, including frame 1, the middle part of frame 1 is provided with crossbeam 12, the top 11 of frame 1 The cylinder body 21 of fixative cylinder pressure, its piston 22 is extended downwardly, and crossbeam 12 is provided with mould 4 in the correspondence position of piston 22, mould 4 It is axially arranged with hollow bulb 41, the internal diameter of the arrival end of hollow bulb 41 is more than the other end, taper transition between two ends, the control of hydraulic cylinder Portion is located in frame 1.Controlled by the effect of hydraulic cylinder control unit, piston can accurately and effectively act on workpiece, Yi Jimo The dimensional standard of tool hollow bulb, can be fixed to workpiece, and the machining accuracy of workpiece is ensured significantly.
As shown in figure 1, piston 22 fixes top board 31, top board 31 is provided with pull bar 32, and pull bar 32 extends downward crossbeam 12 lower ends are connected with lower roof plate 33;Hollow bulb 41 extends downward the lower surface of crossbeam 12, and in the hollow bulb 41 push rod is provided with 34, the lower end of push rod 34 is fixed on lower roof plate 33.Purpose is after work pieces process is finished, in hydraulic cylinder backhaul, by work The power for filling in 22 backhauls ejects workpiece by push rod 34.
Top board 31 and/or lower roof plate 33 are fixed disk, are respectively intended to fixed piston 22 and/or push rod 34.
Pull bar 32 is connecting rod, and it is provided with two, is symmetrically arranged at the both sides of piston 22, for connecting piston 22 and lower roof plate 33。
Utility model works principle:The arrival end that workpiece is put into the hollow bulb 41 of mould 4 is fixed, in the control of hydraulic cylinder In the presence of portion processed, acted on by the pressure of piston 22, rapid, accurate undergauge processing is carried out to workpiece.In the course of processing, work The constancy of volume of part, length, after finishing, in hydraulic cylinder backhaul, push rod 34 are leaned on by work by the power of the backhaul of piston 22 Part is ejected.
