A kind of knife die steel quenching production line, quenching method and knife die steel processing method

Abstract

The invention discloses a cutter die steel quenching production line, a quenching method and a cutter die steel machining method. The cutter die steel quenching production line comprises a feeding device, a clamping, conveying and positioning device for conveying cutter die steel to a preset station, a speed adjusting device used for controlling the feeding speed of the cutter die steel, an electric control device electrically connected with the speed adjusting device and the clamping, conveying and positioning device, a quenching furnace arranged behind the feeding device, a salt-bath furnace which is arranged behind the quenching furnace and internally provided with a band guide roller for pressing the cutter die steel down, a tempering furnace arranged behind the salt-bath furnace, a closed cooling device which is arranged behind the tempering furnace and used for cooling the cutter die steel and a material collecting device which is arranged behind the cooling device and used for collecting materials. According to the cutter die steel quenching production line, an original lead-bath furnace is replaced by the isothermal salt-bath furnace, the production cost is reduced, and it is guaranteed that the surrounding environment is not corroded; and the cooling device is of a closed structure, collection of smoke in a sealed cavity is achieved, and it is guaranteed that the surrounding environment is not polluted and air purification is kept.

Description

technical field [0001] The invention relates to the technical field of die steel production equipment, in particular to a die steel quenching production line, a die steel quenching method and a die steel processing method. Background technique [0002] At present, the production of die steel is mainly processed by the following processes: 1) Pickling: pass the raw material of the die steel coil through a pickling line to remove rust and dirt; 2) Slitting: pass the pickled raw material through the pickling line 3) Rolling: The die steel strip that has passed through the slitting machine is flattened by the rolling mill to be basically formed; 4) Heat treatment: The rolled die steel strip is quenched and tempered by the heat treatment line. Improve the hardness and toughness of the die steel; 5) Sharpening: the die steel strip is graded by five grinding wheels according to the requirements of the cutting edge; 6) Polishing: use a polishing machine to polish the cutting edge of...

Problems solved by technology

[0003] The current process 4) heat treatment adopts lead bath furnace heat treatment. Since lead is used as the heat treatment medium, lead is an element harmful to the human body. Although it is collected and treated to purify the environment, there are still residual harmful components that erode our surroundings. The environment has brought harm to our life and work; after heat treatment, in order to cool the knife belt to the set temperature quickly, open cooling is adopted, and the smoke generated is collected by the exhaust system and processed, and the cost is low. High, wasteful, and because the cooling device is open, the amount of smoke is large, the temperature is high, the ventilation work cannot be completed in time, and it is difficult to collect and control the surrounding smoke in time, resulting in air pollution in the production workshop, which cannot meet the normal production requirements of the knife belt. need
