Abstract
A hand extrusion tooling for spinning copper pipes is characterized in that three clamping claws are arranged on a three-claw chuck, inner ends of the clamping claws are provided with clamping claw shafts which are perpendicular to the a clamping claw device and provided with rolling drums via bearings, and the end of each rolling drum is reduced to be conical. During usage, a copper pipe is camped by the chuck of a lathe to rotate in high speed, the three rolling drums extrude the end of the copper pipe forcedly after the three clamping claws are manually adjusted slowly via adjusting holes, and the copper pipe can drive the three rolling drums to rotate. As the three sides of the copper pipe are uniform in stress, the copper pipe is not easy to deform to be broken, and then a copper pipe with longer closed end can be machined. Simultaneously, due to the bearings arranged on the rolling drums and the clamping claw shafts, the rolling drums can rotate on the clamping claw shafts more flexibly and can not be locked. In addition, due to the conical end of the rolling drums, a transitional section can be formed on the copper pipe fitting during reducing, and then adverse effect on the copper pipe caused by stress is reduced.
Description
Technical field
The utility model relates to a kind of frock clamp of machining, specifically relates to a kind of extruding frock of manual spinning copper pipe.
Background technology
The pipe fitting of air-conditioning connects in the material, and a part is a copper pipe fitting, and the some of them copper pipe fitting needs the end to receive very carefully, and these copper pipe fittings are unsuitable for the method processing with welding, are the end of drawing copper pipe fitting in the method for extruding mostly.In the prior art, commonly used is single roll-in tube lateral compression copper pipe, owing to be single load bearing, the copper pipe after the gathering is yielding and rupture, difficulty of processing is big, is difficult to process the long copper pipe that closes up, and is higher to workman's specification requirement, working (machining) efficiency is low, and the percent defective height causes production cost very high.
Summary of the invention
The utility model mainly is to solve above-mentioned existing in prior technology technical problem, and a kind of extruding frock of manual spinning copper pipe is provided.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of extruding frock of manual spinning copper pipe, comprise three-jaw chuck, three-jaw chuck is provided with three jaws, the inner of described jaw is provided with the jaw axle, the jaw axle is provided with the roll-in tube perpendicular to the jaw setting on the jaw axle.Lathe dog clamping copper pipe and rotation at a high speed, the three-jaw chuck of extruding frock is near copper pipe and make the end of copper pipe rotate at a high speed between three roll-in tubes, manually slowly adjusting three jaws makes three roll-in tubes firmly push the copper pipe end, because copper pipe three sides are evenly stressed, copper pipe is not yielding, greatly reduces difficulty of processing, helps improving working (machining) efficiency, also reduced percent defective, can reduce production costs
As preferably, described roll-in tube is arranged on the jaw axle by bearing, and the roll-in tube rotates more flexibly on the jaw axle like this, prevents locking phenomenon.
As preferably, the termination of described roll-in tube is drawn in and is taper, and the roll-in tube termination of taper makes copper pipe fitting form changeover portion easily when drawing in, reduces the adverse effect that the copper pipe stress is brought.
The utility model is to have done some improvement on the basis of original three-jaw chuck, designs comparatively ingenious, simple in structure, rationally distributed, simplified the production technology that the extruding of existing copper pipe fitting end is drawn in, reduced the production difficulty, help improving working (machining) efficiency, reduce production costs.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: referring to Fig. 1, the utility model is that three-jaw chuck 1 is provided with three jaws 2, and the inner of jaw 2 is provided with jaw axle 3, and jaw axle 3 is provided with perpendicular to jaw 2, by bearing roll-in tube 4 is set on the jaw axle 3, and the termination of roll-in tube 4 is drawn in and is taper.
During use, lathe dog 6 clamping copper pipes 7 and rotation at a high speed, the three-jaw chuck 1 of extruding frock is by the close copper pipe of promotions such as leading screw and make the end of copper pipe rotate at a high speed between three roll-in tubes 4, manually slowly adjusting three jaws by adjustment hole 5 then makes three roll-in tubes firmly push the copper pipe end, copper pipe can drive three roll-in tubes and rotate, because copper pipe three sides are evenly stressed, the not yielding fracture of copper pipe, can process the long copper pipe that closes up, simultaneously because roll-in tube 4 is provided with bearing with jaw axle 3, it is more flexible to make that the roll-in tube rotates on the jaw axle, prevents locking phenomenon; The roll-in tube termination of taper makes copper pipe fitting form changeover portion easily when drawing in, reduces the adverse effect that the copper pipe stress is brought.
At last, should be pointed out that above embodiment only is the more representational example of the utility model.Obviously, the utility model is not limited to the foregoing description, and many distortion can also be arranged.Every foundation technical spirit of the present utility model all should be thought to belong to protection domain of the present utility model to any simple modification, equivalent variations and modification that above embodiment did.
