Chain crater detection method

Abstract

The invention relates to the technical field of manufacturing of protection chains, and in particular relates to a chain crater detection method comprising the steps of S1, stamping a crater of a detection object; and S2, detecting the position of the crater of the detection object, and if the position of the crater of the detection object is cracked, it indicates that the crater is detected to beunqualified. In the technical scheme, the position of the crater of the detection object is stamped, if the crater of the detection object is welded by one or more of cold solder joint and dry joint,the position of the crater is wholly cracked. Therefore, whether the crater is qualified can be easily judged. The defect that when the tensile test mode is used, the detection object needs to be prevented from being deformed under the effect of the tensile force is avoided, and the condition that the detection object flies out and causes a safety accident during a detection process is avoided.

Description

technical field [0001] The invention relates to the technical field of protection chain manufacturing, in particular to a method for detecting chain scars. Background technique [0002] There are various anti-skid chains in the prior art to increase the friction between the tire surface and the ground, so as to avoid accidents caused by vehicle skidding when the road surface is covered with ice or snow. Anti-skid chains are generally composed of a number of welded steel ring links. The application publication number CN108790638A, the invention patent application published on November 13, 2018, discloses an automobile anti-skid chain and its preparation method. By arranging the arc-shaped plate as a straight plate, and then setting an inclined pad on the straight plate, the anti-skid chain is not easily broken during use. [0003] However, no matter how the structure of the anti-skid chain is improved, the occurrence of virtual welding and false welding during the link weld...

Problems solved by technology

This detection method requires that the pressure be stopped immediately when the chain link begins to deform. However, since the softness and hardness of each chain link cannot be completely consistent, the deformation time under the same pressure cannot be exactly the same. Weld scar quality cannot be effectively detected

Therefore, the operability of the welding scar detection method is poor, and it is impossible to realize the automatic detection of welding scars.

However, manual detection is not only inefficient, but also has the risk of the detected chain link flying under the action of pulling force in different directions, causing harm to the operator and posing a greater safety hazard
