Embodiment Construction

[0034] Below, the present invention will be further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of not conflicting, the various embodiments described below or the technical features can be combined arbitrarily to form new embodiments. .

[0035] It should be noted that when a component is said to be "fixed" to another component, it can be directly on the other component or there can also be an intervening component. When a component is said to be "connected" to another component, it may be directly connected to the other component or there may be intervening components at the same time. When a component is said to be "set on" another component, it may be set directly on the other component or there may be an intervening component at the same time. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of illustration only.

Abstract

The invention discloses a manufacturing process of a cold saw circular saw plate. The manufacturing process comprises the following steps that a saw plate is blanked, the saw plate is cut through a laser to form a preformed saw plate; the preformed saw plate is put into a salt bath furnace to be heated to 750-850 DEG C, the preformed saw plate is put into a nitrate furnace for cooling to 150-300 DEG C after the temperature is kept for a period of time; the saw plate is put in a deep cold oven for 8-12 hours heat preservation and taken out and the saw plate is put in air to recover to room temperature; the heat preservation of the saw plate is conducted at 350-450 DEG C tempering temperature for 9-12 hours; continuous multi-times alternating bending is successively conducted on the saw plate in flattening equipment; the saw plate is put in a nickel-based solution with a certain ratio, and under the catalytic action of a catalyst Fe, hypophosphite in the solution conducts catalytic dehydrogenation on the catalytic surface to form a sawtooth cutter head; and the sawtooth cutter head is welded on a circular metal saw plate saw body. After machining is conducted through the above steps,a product is long in service life and greatly improved in performance compared with a conventional cold saw circular saw plate, and the assembly line operation requirement of a customer is met.

Description

technical field [0001] The invention relates to the field of manufacturing, in particular to a manufacturing process of a cold saw circular saw blade. Background technique [0002] At present, in recent years, special-shaped metal-ceramic cold saw circular saw blades have been gradually perfected in sawing common materials or conventional use conditions, but under the conditions of processing special materials and high processing efficiency (such as feed per tooth FZ0.10 or more, speed above 130rpm), the ordinary cold saw circular saw blade can no longer meet the requirements. [0003] In the prior art, the cold saw circular saw blades on the market have the following defects: [0004] Saw blades that have passed the conventional forming process and cutter head grinding process have been unable to meet the specific processing conditions, especially when processing special materials, the severe wear of the cutting edge and the insufficient bearing capacity of the saw blade u...
