Embodiment Construction

[0014] The present invention discloses an anti-splash device 10 for welding bumper crash boxes, such as figure 1 As shown, a base 11 is included, and a groove 12 is opened on the surface of the base 11 for positioning the bumper crash box. In this preferred embodiment, a group of parallel grooves 12 are opened on the surface. Due to the existence of the groove 12 , spatter generated during welding will fall into the groove 12 , and thus will not affect the flatness requirement of the product. When there are many spatters, just clear the groove, which is simple and convenient. In addition, due to the existence of the groove 12, the contact surface with the workpiece to be welded is relatively increased, and a ventilation channel is generated in the groove during welding, which improves the heat dissipation of the workpiece during welding.

[0015] Such as figure 2 As shown, in the second embodiment of the present invention, a group of second grooves 13 perpendicular to the ...

Abstract

The invention discloses an anti-splashing device for welding a bumper bar energy absorption box. The anti-splashing device for welding the bumper bar energy absorption box comprises a base, wherein a groove is formed in the surface, used for positioning the bumper bar energy absorption box, of the base. The anti-splashing device for welding the bumper bar energy absorption box has the main advantages of being simple in structure, effectively preventing producing of splashing in welding, and improving heat dissipation performance of welded workpieces in welding.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to an anti-splash device for welding an energy-absorbing box of a bumper. Background technique [0002] The car bumper is a safety device that absorbs and moderates external impact and protects the front and rear of the car body. The energy-absorbing box of the bumper will produce a lot of welding spatter during the welding process. These spatters often adhere to the positioning plane of the bottom plate of the energy-absorbing box, seriously affecting the flatness requirements of the product, and it is difficult to remove the spatter, which seriously affects the welding progress. Contents of the invention [0003] In view of the above-mentioned defects in the prior art, the object of the present invention is to propose an anti-splash device for welding bumper crash boxes, which solves the problem of more spatters during welding and difficulty in eliminating them. [0004] The ...
