Forming method of wrench tool blank material

Abstract

Disclosed is a forming method of a wrench tool blank material. The forming method comprises the steps of material preparation, squeezing and stretching, first swaging, and second swaging; in the material preparation step, a cylindrical rod is prepared; in the squeezing and stretching step, the rod is squeezed and stretched into a plate-like blank product, and the blank product comprises a plate shank part, a first end part and a second end part, wherein the first end part and the second end part are located at the two opposite ends of the plate shank part correspondingly; in the first swagingstep, the first end part is forged and molded to form a first head; and in the second swaging step, the second end part is forged and molded to form a second head, and a wrench tool blank material ismade. The forming method does not need the steps of heating, cooling, material removing and the like, thereof, processes can be simplified, electricity and work hours can be saved, and relative cost increasing due to waste material producing can also be avoided, and resource wasting is avoided.

Description

technical field [0001] The invention relates to a forming method, in particular to a forming method for blanks used to make wrench tools. Background technique [0002] The wrench tool is a very popular hand tool. When using it, the head of the wrench tool is used to clamp the nut first, and then force is applied to the handle part of the wrench tool, so that the user can tighten or loosen the nut and the screw with less effort. The head of the wrench tool can be a U-shaped opening, or a closed opening with internal serrations, even allowing the user to tighten or loosen without turning the head. A ratchet mechanism that is removed by a nut or screw. Since the wrench tool has two opposite ends, it is common to have different types of heads on both ends of the wrench tool for added functionality. [0003] refer to figure 1 When the above-mentioned wrench tool is made, the unprocessed metal raw material 11 is first formed into a blank 12, and then the blank 12 is made into a...

Problems solved by technology

[0004] However, the aforementioned blank 12 molding method not only needs to use a heating device to heat and soften the raw material, but also needs to stand the raw material 11 for a period of time to cool and shape it. The process is cumbersome and requires a lot of power and man-hours.

In addition, the material removal step is to remove redundant materials by means of cutting, etc., so waste materials will be generated, resulting in increased cost and waste of resources
