Embodiment Construction

[0008] The present invention will be further described below in conjunction with accompanying drawing.

[0009] Taking a key with a hexagonal socket and a screwdriver as an example, zinc alloy is used to press and form a hexagonal socket 2, a screwdriver 3, and a hanging ring 4 on a cold die-casting machine. Screwdriver 3, through hanging ring 4—surface grinding, polishing, cleaning, phosphating and chrome plating—surface and shape inspection—functional test: in addition to the function of key 1, hexagonal port 2 elastic nuts can be used, and screwdriver 3 can be used to screw screws, hanging ring 4. The key 1 can be hung on the key 1 ring, and it is qualified to realize the above functions.

Abstract

The invention discloses a manufacturing technology for a key with an inner hexagon wrench and a screwdriver. A hexagon wrench, screwdriver and hanging ring key integrated blank is formed on a cold diecasting machine through pressing with a zinc alloy, integral burr removal is conducted, hexagon wrench, screwdriver and hanging ring correction is conducted, surface grinding, polishing, cleaning andphosphorization chroming are conducted, and surface and shape checking and function testing are conducted. According to the manufacturing technology for the key with the inner hexagon wrench and thescrewdriver, orderly production and installation can be conducted according to the standard, accordingly, the product manufacturing quality and requirement can be guaranteed, and unrelated and unnecessary links are reduced; the raw materials can be saved, cost is reduced, and the machining, installing and producing processes are kept on the rails and are safe and orderly.

Description

technical field [0001] The invention relates to a process of making an inner hexagonal wrench embedded in a key handle to carry a convenient tool, that is, a key manufacturing process with an inner hexagonal wrench and a screwdriver. Background technique [0002] Each product has its unique production and processing methods, and the different structures and materials of the product will also have a very different installation process from other products. According to the characteristics of the product, a more complete and most suitable production and installation process can be made. There are fewer detours in the production and installation process, and at the same time, it can save manpower, material resources and raw materials, and produce high-quality and low-cost products safely and quickly. The keys with hexagonal socket and screwdriver are non-standard products, so the production Manufacturing is singular and particular, which determines that the manufacturing of comp...
