Abstract

The present invention relates to a manufacturing process of a wrench. The manufacturing process mainly includes steps of forging, annealing, rolling, punching, drawing, polishing, surface-grinding, rough-processing with CNS, heat treatment, vibrating, galvanizing, fine-processing with CNC or MC and integrating to complete the manufacture of roller wrench. By means of adding the heat treatment and the fine processing step with CNC or MC, the present invention strengthens the overall structure of the roller wrench. Meanwhile, the containing space at the head of the roller wrench is slightly deformed after the heat treatment through the fine processing with CNC or MC so as to achieve the desired roundness. After a toothless ratchet is disposed in the containing space of the roller wrench, the toothless ratchet can be engaged with the wall of the containing space with the fine trace of lathe tool resulting from the fine processing done by CNS or MC to increase the engagement force of the brake block of the toothless ratchet.

Description

1229625 V. Description of the invention (1) The present invention relates to a manufacturing method. The technical field relates to the manufacturing process of wrenches, especially a type of rolling wrenches. Annealing and polishing, procedures, lathe grinding, re-plating, and then the wrenches of the wrenches and the purpose of the wrenches, and their functions However, it is high enough. The friction products between the gear teeth are aimed at—general wrenches (two) drums, flat grinding and forming, and repetitive processing and frequent vibration. (7) Forming from forging, high application, and so on. This kind of manufacturing; function, the friction in the body, so that the contact force of the wrench will be insufficient to produce, for general, such as one-way but without ratcheting of the inner ring watch wrench body, it will be easy to make it practical If the surface is not uniform, the pull can only be performed by the previous technology.] (1) (4) punch, (5) drawing, (8) vibration, (9) fire softening, easy processing, barrel forming, and curved surface The process of polishing and final cutting on the material into a general wrench. The process of the wrench cannot be a roller wrench, because of its ratchet, it depends on the surface of the wheel. The inner ring that is matched with its rollers needs to be particularly rigid. If it is obtained by using a traditional wrench, it can still produce the inconvenience of external use, because it causes deformation, but the true roundness is not, and the stress can not be suffered. A flat hand cannot completely reach the control. It is called a defective product. It uses forging, (two systems, (six) assembly, etc. to remove carbon deposits, punches against the plane research force 17 I, and waits for electricity to meet a specific seemingly early ratchet. The surface of the outer ring is manufactured to the same degree as the plate and the roundness. If the hardness is not enough, it will be dispersed evenly. The effect is not long.
