Technical field
The invention belongs to the caliber constriction device in the materials in the tube process technology.
Background technology
In the prior art, a lot of industries all need the caliber of pipeline section is contracted to the setting size to meet the following process demand when producing.A kind of traditional draw mode is mould extruding, namely is that a mould is set first, then at mould one end materials in the tube is reached the purpose of the draw by extruding, and there is following defective in the draw mode of this mould extruding: easily cause not polishing of materials in the tube surface, be prone to burr; The end of materials in the tube can only be shunk, any pipeline section of materials in the tube can not be shunk.And other pipe reduction device of prior art all ubiquity complex structure, cost high, be prone to the defective such as burr.Therefore, still be necessary to develop a kind of simple in structure, easy to operate, caliber constriction device that cost is low, effective.
Summary of the invention
In order to overcome defects, the invention provides a kind of caliber constriction device, this caliber constriction device can compress materials in the tube, the materials in the tube caliber is dwindled, and the materials in the tube surface finishing behind the draw, size are accurate, applied widely, again and simple in structure, easy to implement.
The present invention for the technical scheme that solves its technical problem and adopt is:
A kind of caliber constriction device, comprise the rotation pedestal, at least three eccentric cams and locating shaft, described rotation pedestal is fixedly connected with rotating shaft, described rotating shaft is connected with external impetus equipment, the quantity of described locating shaft is consistent with the quantity of described eccentric cam, one end of described locating shaft is fixedly connected on described rotation pedestal, the other end of described locating shaft connects described eccentric cam, described eccentric cam is positioned the described locating shaft other end and can rotates freely around described locating shaft, all locating shafts are parallel to each other and evenly are distributed in ringwise the rotation pedestal, and the gap that all eccentric cams surround is configured for the machining position of accommodating processed materials in the tube.
The present invention for the further technical scheme that solves its technical problem and adopt is:
Say that further each described eccentric cam offers a locating hole, the other end of described locating shaft inserts in the described locating hole, is provided with clutch shaft bearing in the described locating hole, and the other end of described locating shaft is connected by described clutch shaft bearing with described locating hole.
Say that further described clutch shaft bearing is ball bearing.
Say that further the center of described rotation pedestal offers the materials in the tube perforation, described materials in the tube perforation runs through described rotation pedestal and corresponding with described machining position position.
Say that further described rotation pedestal is the stainless steel pedestal.
Say that further described locating shaft is stainless steel.
Say that further described eccentric cam is the stainless steel eccentric cam.
The invention has the beneficial effects as follows: caliber constriction device of the present invention comprises the rotation pedestal, at least three eccentric cams and locating shaft, the rotation pedestal is fixedly connected with rotating shaft, rotating shaft is connected with external impetus equipment, the quantity of locating shaft is consistent with the quantity of eccentric cam, one end of locating shaft is fixedly connected on the rotation pedestal, the other end of locating shaft connects eccentric cam, eccentric cam is positioned the locating shaft other end and can rotates freely around locating shaft, all locating shafts are parallel to each other and evenly are distributed in ringwise the rotation pedestal, the gap that all eccentric cams surround is configured for the machining position of accommodating processed materials in the tube, materials in the tube are inserted in the machining position place, rotating shaft and rotation pedestal drive all eccentric cam one superhigh speed revolution, the eccentric cam of revolution contacts rear because the effect of frictional force produces again the rotation around locating shaft with materials in the tube at a high speed, push by eccentric cam rotation at a high speed and the tube wall of revolution to materials in the tube, reach the purpose of compression caliber.
Description of drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is the another side view of Fig. 1.
The specific embodiment
Embodiment: a kind of caliber constriction device, comprise rotation pedestal 1, at least three eccentric cams 2 and locating shaft 3, described rotation pedestal 1 is fixedly connected with rotating shaft 4, described rotating shaft 4 is connected with external impetus equipment, the quantity of described locating shaft 3 is consistent with the quantity of described eccentric cam 2, one end of described locating shaft 3 is fixedly connected on described rotation pedestal 1, the other end of described locating shaft 3 connects described eccentric cam 2, described eccentric cam 2 is positioned described locating shaft 3 other ends and can rotates freely around described locating shaft, all locating shafts are parallel to each other and evenly are distributed in ringwise the rotation pedestal, and the gap that all eccentric cams surround is configured for the machining position of accommodating processed materials in the tube.
