Problems solved by technology

[0002] At present, in the production of hollow stainless steel door handles, argon arc welding is generally used for direct production. This traditional method often has unstable missing welding or burn-through defects, especially when using argon arc welding without welding wire. , due to the fact that there will inevitably be welding defects at the start and end of welding, resulting in a large number of defective products, and defective products are generally difficult to repair and reuse, most of them need to be scrapped, resulting in waste, and the ultra-low yield rate limits production
Moreover, in the product strength test of products produced by this traditional method, it is difficult for ordinary panel studs to meet high-strength tensile requirements without reinforcing ribs.

Embodiment Construction

[0019] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0020] 1) handle handle

[0021] Preforming: The upper piece and the lower piece of the handle are formed by stamping. The upper piece and the lower piece have the same structure and are arranged symmetrically up and down. Therefore, the structure of the upper piece is taken as an example. see figure 1 and figure 2 , figure 1 The structure of the above sheet 1 is taken as an example for description. Extended ends 11 are respectively formed at the welding starting point and the welding receiving point after the upper piece 1 and the lower piece are combined into a handle. Then the upper piece and the lower piece are compressed to form the handle 3 by a pre-forming punching machine, and then at the inner arc surface of the handle, two positio...

Abstract

A manufacturing process for a door handle comprises the following steps: handle treatment: fixing two spot welding positions of an upper plate and a lower plate which are provided with lengthening ends together, and then carrying out seamless welding on the upper plate and the lower plate to form a handle finished product; and assembling a panel, a treated handle and a double-screw bolt accordingto a traditional process to form a door handle finished product. Welding defects do not exist on welding initiating and welding ending positions of the handle in the door handle, the reject ratio is reduced to be five percent from the original fifty percent, the cost is reduced by fifty percent, and the production period is shortened.

Description

technical field [0001] The invention relates to a door handle, in particular to a manufacturing process of the door handle. Background technique [0002] At present, in the production of hollow stainless steel door handles, argon arc welding is generally used for direct production. This traditional method often has unstable missing welding or burn-through defects, especially when using argon arc welding without welding wire. , due to the inevitable welding defects at the start and end of welding, a large number of defective products are caused, and defective products are generally difficult to repair and reuse, and most of them need to be scrapped, resulting in waste, and the ultra-low yield rate limits the production capacity. Moreover, in the product strength test of products produced by this traditional method, it is difficult for ordinary panel studs to meet high-strength tensile requirements without reinforcing ribs. Contents of the invention [0003] The technical p...
