Abstract

The utility model relates to a hydraulic steel tube expanding machine which comprises a base, wherein the base is provided with a fixing plate, a die groove, an oil cylinder and a connection shaft; a machining die is directly installed in the die groove which is connected with the connection shaft; and one end of the oil cylinder driving the connection shaft to move forward is fixed to the connection shaft. When the hydraulic steel tube expanding machine provided by the utility model works, a tube required to be expanded is placed on the base, the die is installed on the die groove, the oil cylinder drives the connection shaft to move so as to expand the inner diameter of the steel tube. The steel tube expanding machine provided by the utility model can be used to expand a deformed part of the tube so as to meet the requirements of a product on ovality and guarantee the inner diameter of the product.

Description

A kind of fluid pressure type steel tube expansion
Technical field
The utility model relates to pipe fitting treatment facility technical field, particularly relates to the fluid pressure type steel tube expansion that a kind of tubular goods hole enlargement is used.
Background technology
In the prior art, the regular meeting of heavy caliber size product runs into the good not or regular meeting of light-wall pipe of ovality and is crushed out of shape, and causes the client to go wrong in follow-up use, and is very difficult for return of goods product treatment, causes finished product to scrap, and cost increases.
The manufacturer of general pipe fitting, when operating for large specification light-wall pipe, regular meeting runs into product and is crushed in handling process and causes distortion, directly affects the ovality of product, the product internal diameter does not reach and requires size in other words, and producer transforms just very difficult again.
The utility model content
For the problems referred to above, main purpose of the present utility model is to provide a kind of fluid pressure type steel tube expansion of tubular goods aligning usefulness.
The utility model solves above-mentioned technical problem by following technical proposals: a kind of fluid pressure type steel tube expansion, described fluid pressure type steel tube expansion comprises base, base is provided with fixed head, mold slots, oil cylinder and connecting axle, processing mold is directly installed in the mold slots, mold slots links to each other with connecting axle, and oil cylinder one end that drives the connecting axle reach is fixed on connecting axle.
In an implementation example of the present utility model, the length of described base is 10 meters.
Positive progressive effect of the present utility model is: the fluid pressure type pipe expanding facility that the utility model provides have the following advantages: the fluid pressure type steel tube expansion that the utility model provides, to need the pipe fitting of hole enlargement to be placed on the base during work, mould is installed on the mold slots, drives connecting axle by oil cylinder and move to finish hole enlargement to pipe diameter.The steel tube expansion that the utility model provides can carry out hole enlargement to the pipe fitting deformation place, to reach product to the requirement of ovality, the product internal diameter size requirement of assurance.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Fig. 1 is structural representation of the present utility model.As shown in Figure 1: the fluid pressure type steel tube expansion that the utility model provides is mainly used in carrying out the usefulness of finishing to the pipe deformation position.It comprises a base 1, and the length of base 1 is 10 meters.Base 1 is provided with fixed head 2, mold slots 3, and processing mold 6 is directly installed in the mold slots 3, and mold slots 3 links to each other with connecting axle 5, drives connecting axle 5 reaches by oil cylinder 4, makes processing mold 6 head into endoporus and carries out hole enlargement.
During work, the pipe fitting 7 of need hole enlargement is placed on the base, processing mold 6 is installed on the mold slots 3, drive connecting axles 5 by oil cylinder 4 and move to finish hole enlargement to pipe diameter.
The steel tube expansion that the utility model provides can carry out hole enlargement to the pipe fitting deformation place, to reach product to the requirement of ovality, the product internal diameter size requirement of assurance.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications; these changes and improvements all fall in claimed the utility model scope, and the claimed scope of the utility model is defined by appending claims and equivalent thereof.
