Embodiment Construction

[0010] 1. See figure 1 , figure 2 , image 3 , Figure 4 and Figure 5 , a kind of upsetting shear straightening testing machine of the present embodiment comprises: bed 1, upsetting mechanism 2, shearing mechanism 3 and straightening mechanism 4, wherein bed 1 and upsetting mechanism 2 are connected by bolts, work Put the sample on the lower heading head 203, and close the bed door 101. When the force reaches the requirement, it can be dropped quickly, and the change of the sample can be used to determine whether it is qualified. The shearing mechanism 3 and the straightening mechanism 4 It is connected with the bed 1 by bolts, wherein the workpiece table 304 and the workpiece supporting table 403 are connected by bolts, and respectively play a role in fixing the workpiece.

[0011] 2. See figure 2 , the bed 1 is composed of a bed door 101, a protective frame 102, and a bed platform 103, wherein the bed door 101 can move up and down in the protective frame 102, and the...

Abstract

The invention provides an upset forging shearing straightening testing machine. According to the technical scheme, a lathe bed and an upset forging mechanism are connected by bolts, during working, asample is placed on a lower upset head, a bed door is closed, rapid falling can be performed when force meets the requirement, whether the sample is qualified or not is determined by observing the change of the sample, a shearing mechanism and a straightening mechanism are connected with the lathe bed by bolts, wherein a workpiece table and a workpiece support table are connected by bolts to playa role in fixing a workpiece correspondingly. The structure has the advantages that the structure is simple, safe, and reliable.

Description

technical field [0001] The invention relates to an upsetting shear straightening test machine, which is used for detecting whether metal parts meet the detection standards, and belongs to the field of metal detection. Background technique [0002] At present, steel is widely used in life and industry, and the requirements for testing whether its strength is qualified are extremely high. However, to test whether its strength is qualified, it needs to reach a large value under a specific temperature environment. And quickly drop the axial direction of the sample, compress the sample, test the ability of the metal to withstand the plastic deformation of upsetting under the specified forging ratio and show the surface defects of the metal. In principle, it is required to determine the ultimate plastic deformation capacity of the sample material under specified conditions, and to expose the defects on the surface of the sample. The previous detection methods are highly dangerous,...
