Abstract

The invention discloses a pipe expander. The pipe expander comprises a frame and is characterized in that the frame is provided with a steel pipe locating and clamping device, wherein a pipe expanding device and a steel pipe limiting device are respectively arranged on the two sides of the steel pipe locating and clamping device. The pipe expander has the beneficial effects of being scientific and reasonable in structural design, beneficial for an enterprise to secondarily machine purchased steel pipes into finished products which satisfy the self-demands, low in manufacturing cost of overall equipment, capable of effectively saving the equipment purchase cost of the enterprise and beneficial for lowering the production cost of products.

Description

A kind of electric tube expander
Technical field
The present invention relates to steel pipe processing technique field, particularly relate to a kind of electric tube expander.
Background technology
At bicycle manufacture field, usually there is the situation that caliber and actual needs are not inconsistent in the pipe of outsourcing, for the caliber changing set pipe, prior art can adopt relevant equipment to expand caliber, but such device structure is complicated usually, purchase cost is higher, is unfavorable for that enterprise reduces the production cost of self.
Summary of the invention
In view of above content, the invention provides that a kind of structure is simple, cost is low and the electric tube expander that working (machining) efficiency is high.
For achieving the above object, the technical solution adopted for the present invention to solve the technical problems is:
A kind of electric tube expander, comprises frame, it is characterized in that: in described frame, be provided with steel pipe positioning clamping device, have pipe-expanding device and steel pipe stopping means respectively in described steel pipe positioning clamping device both sides;
Described steel pipe positioning clamping device comprises positional cylinder, positional cylinder fixed head, steel pipe location patrix and steel pipe location counterdie, described positional cylinder is connected with described positional cylinder fixed head, described positional cylinder fixed head is fixedly connected with described frame, described steel pipe location counterdie is fixedly connected with described frame, and described positional cylinder front end connects described steel pipe location patrix;
Described pipe-expanding device comprises expand tube oil cylinder and expand tube punch, and described expand tube oil cylinder is connected in described frame by an I-steel, and described expand tube punch is connected to described expand tube oil cylinder front end;
Described stopping means comprises locating oil cylinder and spacing punch, and described locating oil cylinder is connected in described frame by an I-steel, and described spacing punch is connected to described locating oil cylinder front end.
Its further feature is as follows:
