Abstract
The utility model discloses a hydraulic expanding machine, and aims to provide the hydraulic expanding machine which has constant pressure and a good expanding effect. The hydraulic expanding machine comprises a machine frame, a workbench arranged on the machine frame, upright posts arranged at the four corners of the workbench, as well as master cylinders which are arranged on the upright posts and can drive a movable cross beam to move up and down. The hydraulic expanding machine is characterized in that at least two auxiliary formation cylinders are arranged on the workbench. Each auxiliary formation cylinder comprises an auxiliary formation cylinder body and an auxiliary formation piston. The auxiliary formation cylinders are arranged on two sides of the workbench and are symmetrical relative to the middle of the workbench. The hydraulic expanding machine provided by the utility model is mainly used for pipe processing and water expanding pipe formation.
Description
Technical field
The utility model relates to a kind of hydraulic machinery, relates in particular to a kind of hydraulic pressure expanding machine.
Background technology
The hydraulic pressure expanding machines that use are processed more with the machine-shaping of tubulose section bar the time, because of the reliability of hydraulic system is that advantages such as stress equalization and constant pressure are able to extensive use.But the function singleness of existing hydraulic pressure expanding machine, converted products flexibly, and in forming process, often have because of insufficient pressure and cause the failure that is shaped.
Summary of the invention
The utility model discloses a kind of hydraulic pressure expanding machine, in order to solving the deficiencies in the prior art, insufficient pressure in the forming process and the problem that causes the bulging waste product to produce.
Technical solution of the present utility model is: a kind of hydraulic pressure expanding machine, comprise frame, be arranged on the workbench on the frame, be arranged on the column of four jiaos of workbench, and be arranged on the column and can drive the master cylinder that moved cross beam moves up and down, it is characterized in that: described workbench is provided with the assistant formation cylinder.
Described assistant formation cylinder is made up of assistant formation cylinder body and assistant formation piston.
At least two in described assistant formation cylinder is arranged on the both sides of workbench and with respect to the middle part symmetry of workbench.
The beneficial effects of the utility model are: because the design of having adopted master cylinder and assistant formation cylinder to match, make in forming process constant pressure, bulging effective, thereby reached the purpose of this utility model.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of assistant formation cylinder of the present utility model;
Among the figure: 1-frame, 2-workbench, 3-column, 4-moved cross beam, 5-master cylinder, 6-assistant formation cylinder, 7-assistant formation cylinder body, 8-assistant formation piston.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.
Referring to accompanying drawing, the utility model comprises frame 1, is arranged on the workbench 2 on the frame 1, be arranged on the column 3 of 2 four jiaos of workbench, and be arranged on and can drive the master cylinder 5 that moved cross beam 4 moves up and down on the column 3, it is characterized in that: described workbench 2 is provided with assistant formation cylinder 6.
Described assistant formation cylinder 6 is made up of assistant formation cylinder body 7 and assistant formation piston 8.
6 at least two in described assistant formation cylinder is arranged on the both sides of workbench 2 and with respect to the middle part symmetry of workbench 2.
When reality is used, mould is placed on the workbench 2, and material to be processed is placed in the mould.Then master cylinder 5 being pressed down drive moved cross beam 4 compresses mould and material.By pressurized cylinder hydraulic pressure is gone in the material this moment assistant formation cylinder 6 simultaneously by under the effect of hydraulic pump hydraulic oil being charged in the assistant formation cylinder body 7 then, hydraulic oil then acts on assistant formation piston 8 and its middle part to workbench is compressed material, because assistant formation piston 8 ends are less than the material external diameter, then assistant formation piston 8 compresses liquid in the material and the position of having stablized material, makes molding effect more remarkable.After moulding is finished assistant formation cylinder 6 backed off and easily the material that processes to be withdrawed from move on the moved cross beam 4 from mould then.
