Problems solved by technology

[0003] In the prior art, the commonly used quenching methods for coal picks include high-frequency induction hardening, laser quenching, etc. Among them, laser quenching is only surface heating, so no tempering treatment is required, and the hardness of the tooth surface of coal picks, the depth of hardened layer and the resistance Performance such as pitting fatigue strength has been significantly improved, because laser quenching has broad application prospects, but the process of laser quenching has high process requirements, pollution during laser quenching, difficult laser protection, and high labor intensity for workers
In the prior art, there are few equipment specially developed for laser quenching of coal picks

Abstract

The invention relates to auxiliary equipment for quenching process, in particular to a laser quenching rack special for cutting picks of a coal cutter. A laser quenching process area is isolated froma receiving area and a conveying area so that harm from pollutants of light pollution and exhaust gas pollution to the human body during the laser quenching is avoided effectively and labor intensityis reduced greatly; the whole laser quenching process has high level of automation, work efficiency of the laser quenching is increased; under cooperation of a conveying belt, a first L-shaped rotaryarm and a second L-shaped rotary arm realizes transferring of the cutting picks, and thus the process can be completed by controlling mechanical arms through an automatic control system during the laser quenching; after finishing the process, the cutting picks are recovered into a collecting barrel automatically through the conveying belt, workers are protected against being scaled by afterheat ofthe processing of the cutting picks, and safety and health of the workers are protected effectively. The laser quenching rack is of reliable structure and capable of improving work efficiency of thelaser quenching process of the cutting picks.

Description

Technical field [0001] The invention relates to auxiliary equipment during quenching processing, in particular to a special laser quenching rack for coal picks. Background technique [0002] The shearer pick is abbreviated as the coal pick. The coal pick is a necessary accessory for the mining machine. It is a vulnerable part used with the shearer and suitable for coal mining. The shape of the coal pick It can be divided into knife-shaped teeth and pick-shaped teeth. According to the material, it can be divided into ordinary picks, wear-resistant picks, hard rock picks, super hard rock picks, sandstone picks, and non-sparking picks. During the mining process According to the strength of the coal being mined, the selected coal pick models are correspondingly different. Commonly used models are U62, U82, U84, U85, U92, U94, U95, etc. The main failure mode of coal picks is knife Head fall off, tool collapse, tool head, tool body wear, etc., coal picks often use 42CrMo steel, 35CrMn...
