Full-automatic drop hammer impact testing machine for pipes

Abstract

The invention discloses a full-automatic drop hammer impact testing machine for pipes, and belongs to the technical field of testing equipment. Which comprises a plurality of hammer heads (20) and is characterized in that a pipe fitting translation frame (9) is arranged on the surface of a fixed frame (8), a pipe fitting lifting frame (7) is arranged in the pipe fitting translation frame (9), and a to-be-tested pipe fitting (5) is placed on the surface of the pipe fitting lifting frame (7); a test opening is formed right above the rear end of the fixed frame (8), and the test opening is positioned above the moving track of the to-be-tested pipe fitting (5) and the hammer head (20); and a hammer head lifting mechanism (1) is also arranged above the test opening. According to the full-automatic drop hammer impact testing machine for the pipe, the hammer head lifting mechanism is arranged, so that grabbing of different hammer heads is realized, meanwhile, the pipe fitting translation frame and the pipe fitting lifting frame in the pipe fitting translation frame are arranged, so that automatic feeding and discharging of the pipe fitting to be tested are realized, and the full-automatic drop hammer impact testing machine is applicable to testing of pipe fittings with different pipe diameters.

Description

technical field [0001] The utility model relates to a full-automatic dropping weight impact testing machine for pipe materials, which belongs to the technical field of testing equipment. Background technique [0002] As plastic pipes are widely used in building materials, construction and other industries, the impact test of plastic pipes has become an indispensable testing item, and testing equipment has also become indispensable for the production, research, use and inspection institutions of plastic pipes. equipment. Impact collision is a common mechanical phenomenon in daily life and engineering applications. Experimental simulation of it is an effective research method, and drop hammer impact testing machine is one of the important experimental equipment. Its basic principle is to use The speed of free fall is used to realize impact loading on the specimen, so as to study the response of materials and structures under impact load. [0003] The traditional drop weight ...

AI Technical Summary

Problems solved by technology

[0003] The traditional drop weight impact testing machine generally has the following defects: (1) The removal and placement of wiped samples before and after the test needs to be done manually, thus affecting the test efficiency

(2) After the hammer head impacts the sample, due to the action of the sample, the hammer head will bounce up and form a secondary impact, which also affects the test effect to a certain extent

(3) The test height of the hammer head is generally fixed. If the test height needs to be changed, other testing machines can only be replaced for testing. Therefore, the applicability of the traditional drop hammer impact testing machine is poor.

(4) The pipe diameter range applicable to the traditional drop weight impact testing machine is relatively small, and pipes exceeding the pipe diameter range of the testing machine cannot be tested

(5) Due to different test items, hammer heads of different weights need to be used, and the replacement of hammer heads is also done manually, and the operation is relatively cumbersome

(6) Since the pipe to be tested will also bounce after being impacted by the hammer head, there are certain potential safety hazards
