Embodiment

[0014] A kind of stud bending device of this embodiment such as image 3 , Figure 4 As shown, it includes a triangular base with a bevel, and the angle between the bevel and the triangular base is 60°; the bevel is vertically provided with a welding stud fixing base.

[0015] The fixing base of the welding stud test piece is provided with a groove, and the groove is perpendicular to or parallel to the slope, and the fixing base of the welding stud test piece is a cube base.

[0016] In the specific test process of welding stud bending in the present invention, a special bending device is used to change manual bending into mechanical oil pressure bending, and the welding stud bending sample is placed in the triangular shape of the special bending device by using test equipment such as a universal material testing machine and a press machine. In the slope groove of the seat, since the slope is inclined 60° to the triangular base, the cylindrical head of the welding stud is ben...

Abstract

The invention relates to a male pin bending device, which belongs to the technical field of metal performance tests. The male pin bending device comprises a triangular base with an inclined plane, wherein the inclination included angle of the inclined plane and the triangular base is 60 degrees; a welding stud fixing base is perpendicularly arranged on the inclined plane. The male pin bending device can not only bend welding studs through pressing machine experiment equipment, but also has a simple structure.

Description

technical field [0001] The invention relates to a special device for bending studs, belonging to the technical field of metal performance testing. Background technique [0002] At present, cylindrical head welding studs for arc stud welding are widely used in shearing parts, buried parts and anchors of various structures in civil engineering engineering. (welding stud) specification requires stud (welding stud) bending test. In the past, domestic physical and chemical testers used hand hammers to hit or use steel casings to press test the heads of studs (welding studs) to make them bend 30° (see figure 1 , figure 2 ). After the test, if there is no visible crack in the weld seam and heat-affected zone of the test piece, the test is deemed to be qualified. Using this artificial bending test method is time-consuming and labor-intensive, and often affects the test effect due to the impact force. Contents of the invention [0003] The present invention aims at the defic...
