Abstract
The utility model relates to high-accuracy bore finishing equipment for tube material. The utility model is characterized in that the high-accuracy bore finishing equipment is composed of a supporting seat, a supporting bushing, a draw rod and general spheres, wherein, the draw rod penetrating through the general spheres is fixed by nuts; a gasket is arranged in the supporting seat; the supporting bushing is screwed on the supporting seat. The utility model can conduct finishing to the internal surface of the tube material, can improve accuracy and surface smoothness in the tube material and can guarantee the final quality of products.
Description
The utility model relates to the processing of metal pipe material, and a kind of high accuracy tubing endoporus calibration devices is provided especially.
For high accuracy tubing, high dimensional accuracy should be arranged, high surface accuracy is arranged again.But in conventional tube rolling process, because the restriction of pipe and each side factors such as tube-rolling technique and instrument, the endoporus precision of tubing is difficult to improve, thereby has influenced the precision of tubing.
The purpose of this utility model is to provide a kind of high accuracy tubing endoporus calibration devices, by using this device internal surface of pipe is carried out finishing, can improve precision and surface smoothness in the tubing greatly, to guarantee final product quality.
The utility model provides a kind of endoporus calibration devices of high accuracy tubing, it is characterized in that: this device is made of supporting base (6), carrying sleeve (3), pull bar (4), logical ball (2); Pull bar (4) passes logical ball (2) and fixing by nut (1); Pad (5) places supporting seat (6), and carrying sleeve (3) is screwed together on the supporting base (6).
Logical ball (2) is the combination of billiard table and frustum in the utility model, and the centre of sphere is apart from L
1Ratio L with logical ball length overall L
1/ L=1: 3～3.5, sphere diameter d and logical ball inner diameter d ' ratio d/d '=2～2.5, the cone angle of frustum is at 4～6 °.
The utility model device mainly solves two problems:
1. guarantee that tubing carries out draw on common drawbench.
2. guarantee that tubing does not lose fringe in the finishing process.This is mainly realized by support column.The tubing of finishing different size will outfit and the sleeve pipe that is complementary of tube outer diameter and length, to increase by the stability of finishing pipe.
Logical ball material will be complementary by the material of finishing pipe, select carbide alloy or bronze etc. usually for use.
With the method for draw rolling back tubing endoporus is carried out finishing, the dimensional accuracy of tubing, the accuracy of form and position (as ovality), surface roughness etc. are all improved a lot.When production high accuracy tubing, the endoporus precision of production tube should be guaranteed by last finishing procedure.Like this, both can guarantee the quality of product, can alleviate the precision control difficulty of last rolling process again.
By embodiment in detail the utility model is described in detail below in conjunction with accompanying drawing.
Accompanying drawing 1 is the structure chart of calibration devices.
Accompanying drawing 2 is logical chou composition.
Embodiment
As shown in Figure 1, the endoporus calibration devices of high accuracy tubing is made of supporting base (6), carrying sleeve (3), pull bar (4), logical ball (2); Pull bar (4) passes logical ball (2) and fixing by nut (1); Pad (5) places supporting seat (6), and carrying sleeve (3) is screwed together on the supporting base (6).As shown in Figure 2, logical ball (2) is the combination of billiard table and frustum, and the centre of sphere is apart from L
1Ratio L with logical ball length overall L
1/ L=3.5, the cone angle of frustum are at 5 °, and d/d '=2 are hard alloy piece, and surface roughness is 0.2.
