Abstract
The invention discloses a silencer bonding production process, comprising the following steps: welding two injection molding parts into a silencer by adopting injection molding part welding equipment; embedding a closed conductive metal ring at the joint of the two injection molding parts, applying a certain pressure, applying an electromagnetic field to the joint, and heating the conductive metal ring through electromagnetic induction, so that the injection molding parts are fused and cooled at the joint and then bonded together; and further comprising: detecting the welding effect of the injection molding parts through welding detection equipment. According to the silencer bonding production process, the conductive metal rings are embedded into the contact surfaces of the two injection molding parts forming the silencer, and the conductive metal rings are heated in an electromagnetic induction mode, so that the surfaces, making contact with the conductive metal rings, of the injection molding parts are molten, and the two injection molding parts can be bonded and form the silencer after being cooled. In addition, the welding detection device is used for detecting the welding result, the welding strength is guaranteed, and defective products are avoided.
Description
Technical field [0001] The present invention relates to the field of silencer production, in particular a muffler bonding production process. Background technique [0002] Due to the particularity of the structure, the existing partial injection molded parts generally use the first partially injection molding, re-combined production process, and the combined molding method used by the glue bonding is gradually replaced by environmental protection, cost and other reasons. . Common welding methods include hot plate welding, rotating welding, ultrasonic welding, high cyclic welding, hot melt fitting, and hotline welded. A method of fusion of a plastic article is disclosed in the Chinese invention patent application of CN103612383A. It is to be placed at two plastic parts seams with a tail non-connected steel wire, and applied to two plastic parts. At the same time of pressure, the steel wire passes through a certain current such that the plastic member is melted at the seam, and the...
