Abstract
The utility model provides a copper pipe hole enlargement head support cover free of pipe lubrication. An oil distributor is arranged at a front cover of the support cover, an annular oil channel C1 and an annular oil channel C2 are arranged on the connection surface between the front cover and a rear cover, the annular oil channel C1 and the annular oil channel C2 are all provided with V-shaped sealing rings respectively, the annular oil channel C1 is communicated with an oil inlet D1 in the rear cover, and the annular oil channel C2 is communicated with an oil inlet D2 in the rear cover, and the annular oil channel C1 is communicated with the oil distributor by an oil line 6 in the front cover, the annular oil channel C2 is communicated with the oil distributor by an oil line 7 in the front cover, the oil distributor is communicated with an oil line 8 and an oil line 9 in the front cover respectively, and the front cover and the rear cover are connected by a screw. Through the support cover, the defect that an external oil line is required for supplying oil to the oil distributor is overcome, so that the damage on a friction pair caused by the failure of an oil pipe is avoided, and the support cover is suitable for hole enlargement heads with small specifications.
Description
Technical field
The utility model relates to the manufacture field of steel pipe, and specially referring to does not have the lubricated pipe expanding head support set of pipe.
Background technology
The steel pipe of larger caliber need carry out the total length hole enlargement with the machinery expanding machine usually in process, with the reduction pipe residual stress, and obtain good physical dimension.The hole enlargement head is the critical component of expanding machine, and it realizes that through the relative slip of cover external mold on cone the outer of external mold rises and retraction, thereby accomplishes the expansion of diameter of steel tube.A hole enlargement support set is mainly used in the vertically-guided to a hole enlargement external mold.
Between a hole enlargement support set and the external mold is sliding friction pair, adopts pipeline to give oil lubrication usually, to prolong die life in good time.Since many to oil drop, so need to arrange multiple-tubing string and joint on the support set, when their occur leaking or rupture, will cause friction pair to damage because of fuel feeding is not enough.
Summary of the invention
The purpose of the utility model is to provide a kind of lubricated pipe expanding head support set of no pipe that need not to assemble external oil pipe.
For realizing above-mentioned purpose, the technical scheme of the utility model is:
A kind of do not have a lubricated pipe expanding head support set of pipe, comprises preceding body, separator, V-shaped seal ring, back body, on the preceding body of this support set separator is housed, and on the joint face of preceding body and back body, has annular oil groove C
1With annular oil groove C
2, annular oil groove C
1With annular oil groove C
2On V-shaped seal ring is housed, annular oil groove C respectively
1With the oil-in D in the body of back
1Be connected annular oil groove C
2With the oil-in D in the body of back
2Be connected annular oil groove C
1Be connected annular oil groove C with separator through the oil circuit in the preceding body 6
2Be connected with separator through the oil circuit in the preceding body 7, separator respectively with preceding body in oil circuit 8 be connected with oil circuit 9, preceding body overlaps the body and function screw with the back and is connected.
The good effect of the utility model is:
1, this support set has overcome the drawback with external pipeline fuel feeding to separator, thereby has avoided losing efficacy to the damage of friction pair because of oil pipe;
2, be particularly useful for the less hole enlargement head of specification;
3, this support set is simple in structure, easy to operate.

Fig. 3, the lubricated pipe expanding head support set A-A view of nothing pipe.
The specific embodiment
Further specify the specific embodiment of the utility model below in conjunction with accompanying drawing 1-3.
Referring to Fig. 1-3, before the use pipe expanding head support set, preceding body 1 is connected with back body 5 with screw 3, make annular oil groove C
1With the oil-in D in the back body 5
1Be connected annular oil groove C
2With the oil-in D in the back body 5
2Be connected, and guarantee to be contained in annular oil groove C
1Become C with annular oil groove
2On V-shaped seal ring 4 oil-proof, lubricating oil is through the oil-in D in the body 5 of back
1With oil-in D
2Get into annular oil groove C respectively
1With annular oil groove C
2In, through with annular oil groove C
1The oil circuit 6 that is connected and with annular oil groove C
2The oil circuit 7 that is connected gets in the separator 2, is delivered on the lubricated face by oil circuit that is connected with separator 28 and oil circuit 9 again, makes sliding friction pair can carry out work smoothly.
