Embodiment Construction

[0015] The technical solutions of the present invention will be clearly and completely described below in conjunction with specific embodiments.

[0016] A saw blade forging forming process disclosed by the present invention specifically includes the following steps:

[0017] a. Material preparation: 20MnTiB is selected as the saw blade raw material;

[0018] b. Raw material reformation: surface pretreatment of saw blade raw materials, specifically pickling → shelling → lubrication → rough drawing → pickling → lubrication → fine drawing;

[0019] c. Forging: The saw blade is hot-forged in the high-frequency induction heater at a temperature of 900°C-1000°C. The frequency of the high-frequency induction current is 20,000-40,000 Hz, and then the punching machine is used to cooperate with the forging die for forging Forging operation, the forging temperature is controlled at 600~650°C, and the number of forging times is not more than 20;

[0020] d. Shot blasting: remove the sc...

Abstract

A saw blade forging forming process disclosed by the present invention includes the steps of material preparation, raw material reformation, forging, shot blasting, heat treatment, cryogenic treatment and post-treatment. The saw blade forging forming process provided by the invention solves the delayed fracture and fatigue fracture of the saw blade under high strength, is not easy to break during use, has reliable connection, and improves the service life of the saw blade.

Description

technical field [0001] The invention relates to a production method of a saw blade, in particular to a forging forming process of the saw blade. Background technique [0002] In the field of construction, construction workers often need to cut on wood, ceramic tiles, floor tiles and other materials, and there are usually cutting particles on both sides of the edge of the saw blade base of ordinary saw blades, resulting in uneven thickness of the saw blade. It is easy to bend, which affects the quality of the building. Contents of the invention [0003] The object of the present invention is to provide a saw blade forging forming process, which has a relatively simple process, low manufacturing cost, good process continuity, high production efficiency, and a longer service life of the saw blade. [0004] The technical solution of the present invention is: a forging and forming process of saw blades, which specifically includes the following steps: [0005] a. Material p...
