Abstract
The utility model discloses a pipe expander, include: frame body and rotating cutter head, the below middle part of frame body is provided with the expand tube workstation, rotating cutter head sets up the top middle part at the frame body, rotating cutter head is last to be provided with a plurality of knife rests, install the expand tube cutter of a plurality of different diameters on the knife rest, the expand tube cutter includes cutter arbor and tool bit, the tool bit is a ball type, the expand tube workstation includes fixing base and rubber circle, the cutter arbor drives the tool bit activity and inserts in the rubber circle. In this way, the utility model discloses can a cold working accomplish the expand tube, machining efficiency is high, and processingquality is stable.
Description
Technical field
The utility model relates to Machining Technology field, particularly relates to a kind of tube expander.
Background technology
In prior art, tube expander is applied to multiple industry, different according to the specification requirement of industry product, production technology is also different, for for the copper pipe in air conditioner, traditional expansion tube process is for carrying out expand tube after needs hot-working, and processing cost is high, and be easily out of shape, the product quality after expand tube is lower.
Utility model content
The technical problem that the utility model mainly solves is to provide a kind of tube expander, and a cold working can complete expand tube, working (machining) efficiency is high, and crudy is stablized.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: provide a kind of tube expander, comprise: frame body and rotary head, expand tube workbench is provided with in the middle part of the below of described frame body, described rotary head is arranged on the upper center of frame body, described rotary head is provided with multiple knife rest, described knife rest is provided with the expand tube cutter of multiple different-diameter, described expand tube cutter comprises knife bar and cutter head, described cutter head is a ball-shaped, described expand tube workbench comprises holder and rubber ring, the activity of described knife bar band dynamic cutter head is inserted in rubber ring.
In the utility model preferred embodiment, its diameter of expand tube cutter of described multiple different-diameter becomes successively and arranges with sequence counter-clockwise greatly.
The beneficial effects of the utility model are: the utility model adopts gradual expansion tube process, progressively expands copper pipe, and damage little to the pipe shaft of copper pipe, and expand tube is stablized, working (machining) efficiency is high.
Accompanying drawing explanation
Fig. 1 is the perspective view of the utility model tube expander;
Fig. 2 is the expand tube operating diagram of the utility model tube expander;
In accompanying drawing, the mark of each parts is as follows: 1, frame body; 2, rotary head; 3, expand tube workbench; 20, knife rest; 21, expand tube cutter; 30, holder; 31, rubber ring; 210, knife bar; 211, cutter head.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection domain of the present utility model.
Refer to Fig. 1 and Fig. 2, the utility model embodiment comprises: a kind of tube expander, comprise: frame body 1 and rotary head 2, expand tube workbench 3 is provided with in the middle part of the below of described frame body 1, described rotary head 2 is arranged on the upper center of frame body 1, described rotary head 2 is provided with multiple knife rest 20, described knife rest 20 is provided with the expand tube cutter 21 of multiple different-diameter, described expand tube cutter 21 comprises knife bar 210 and cutter head 211, described cutter head 211 is a ball-shaped, described expand tube workbench 3 comprises holder 30 and rubber ring 31, described knife bar 210 is with dynamic cutter head 211 activity to be inserted in rubber ring 31.
Furtherly, its diameter of expand tube cutter 21 of described multiple different-diameter becomes successively and arranges with sequence counter-clockwise greatly.
The operation principle of the utility model tube expander: first band processing copper pipe is placed in rubber ring and carries out pretension and fix, knife rest 20 is installed the expand tube cutter 21 of different-diameter, then rotary head 2 is rotated, first minor diameter expand tube cutter 21 inserts in copper pipe and carries out first time expand tube, then again rotary head 2 is rotated, second middle diameter expand tube cutter 21 inserts in copper pipe and carries out the second expand tube, according to product needed, carries out expand tube from small to large successively.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
