Carbide round bar drop strength tester

Abstract

The invention discloses a hard metal round rod landing strength tester which comprises a horizontal base, a lifting device and a wheel. The lifting device provided with a supporter is mounted on the horizontal base vertically; the wheel is supported on the supporter and capable of running freely; the outer edge of the wheel is provided with axially U-shaped grooves along the periphery. An upright is mounted beside the lifting device and is provided with a bevel lifting device; a bevel vibrator is mounted on the bevel lifting device; an inclined bevel structure is fixed to the bevel vibrator; the lower end of the bevel structure faces the wheel and is connected with the same. By means of bevel vibrating type feeding, labor intensity of operators is reduced. The wheel runs continuously to drive the U-shaped grooves to run to a joint so as to carry round rods and then runs to the other side to release the round rods, the round rods then fall freely with uniform landing stress; thus, strength testing requirements for the hard metal round rods during landing test are met well. Besides, automatic feeding and semi-automatic testing are achieved.

Description

technical field [0001] The invention relates to a landing strength detector of a cemented carbide round bar, which is used for detecting the landing strength of a cemented carbide round bar and rod-shaped metal or non-metal objects whose landing strength cannot be detected by other conventional detection methods. Background technique [0002] At present, the quality inspection of cemented carbide round rods usually uses a landing test to detect cemented carbide round rods, but the conventional landing test uses manual operation, rolling down cemented carbide round rods from slopes of different heights. This detection method Controlled by the operator, it cannot be guaranteed that the two ends of the cemented carbide rods will fall at the same height. Generally, due to the uneven landing force, a large number of cemented carbide rods will break, resulting in a high false detection rate. Contents of the invention [0003] The purpose of the present invention is to overcome t...
