A metal pipe sample punching equipment

Abstract

The invention discloses punching equipment for samples of metal pipes. The punching equipment comprises a punch and is characterized by further comprising a pipe positioning mechanism and a pipe punching mechanism, wherein the pipe positioning mechanism comprises a base fixed on a workbench, and a clamping positioning structure is arranged on the base; the pipe punching mechanism comprises a punch connection push rod; a conical spindle connecting head is arranged at the upper end of the punch connection push rod and is butt-jointed with a mounting connecting port at the lower end of a spindle of the punch; a pipe punching tool is arranged at the lower end of the punch connection push rod; two vertically downward and rectangular cutting parts are arranged on the left side and the right side of the lower end of the pipe punching tool; cutting edges arranged horizontally in the front-and-back direction are arranged at lower ends of the cutting parts; the two cutting parts directly faces a punching channel, and the distance between two sides is smaller than the width of the punching channel. The punching equipment has the advantages that the structure is simple, the equipment is convenient and rapid to operate, the pipe sampling efficiency is high, deformation of the obtained samples is small, the quality is high and the like.

Description

technical field [0001] The invention relates to the field of performance testing of metal pipes, in particular to a metal pipe sample punching equipment. Background technique [0002] With the application of metal pipes more and more widely, customers have higher and higher requirements on the quality of metal pipe products, such as mechanical strength and corrosion resistance. Therefore, before the production process or the use of pipes, it is often necessary to carry out Sampling and testing, testing its mechanical properties, corrosion resistance and biofilm performance in water flow environment, etc. [0003] However, in the process of sampling and testing pipes, especially metal thin-walled pipes, if the entire pipe is used for mechanical testing and corrosion resistance testing, it will not only reduce the efficiency of testing, but also cause a lot of waste. In order to improve efficiency and reduce waste, it is usually necessary to cut the pipe sample along the axia...

AI Technical Summary

Problems solved by technology

The above existing pipe sampling technology has the following defects: 1. The clamping end face of the pipe sample needs to be turned on a lathe to process the clamping end face. After one end face of a pipe sample is machined, it is necessary to re-clamp and position the sample. More complex, lower sample preparation efficiency

2. The outer wall of the pipe sample needs to draw parallel lines, clamp the end face of the pipe for positioning, and after cutting a sheet sample, the sample needs to be re-clamped and positioned. The process is more complicated and the sample preparation efficiency is low.

3. When the planer device is planing and sampling the sheet sample, the end face and the marking line of the pipe are used to locate the cutting position of the pipe, so the dimensional accuracy of the sample is not high

4. When the planer is planed and processed to sample the sheet material, the sample deformation of the thin-walled pipe is often serious during the processing process. In many cases, the sample cannot be planed directly, and the subsequent fitter needs to use clamps to test the sheet material. The sample is separated from the sample tube, and then the sample is flattened, which is time-consuming and labor-intensive

And the surface quality of the sample is affected to a certain extent, resulting in inaccurate test results and affecting the detection accuracy of the sample

5. This set of sample preparation process uses many types of machine tools, and the processing steps are cumbersome, time-consuming and labor-intensive

The cost of labor and equipment is higher
