Description

A special laser quenching frame for coal picks

technical field

The invention relates to auxiliary equipment during quenching, in particular to a special laser quenching frame for coal picks.

Background technique

Shearer picks are referred to as coal picks for short. Coal picks are necessary accessories for coal shearers during mining. They are vulnerable parts that are used in conjunction with shearers and are suitable for coal mining. 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-spark picks. According to the different hardness of the coal to be mined, the type of coal pick used is also different. The commonly used models are U62, U82, U84, U85, U92, U94, U95 and other models. The main failure mode of coal pick is knife Coal picks often use 42CrMo steel, 35CrMnSi steel and other steel as the tooth body material, and generally use pure alloy material around the hard alloy knife to make the coal pick wear-resistant. Overlay welding and quenching treatment can make the service life of coal picks longer, more wear-resistant, higher density, and less prone to decarburization. For coal picks that need to be repaired due to wear, surfacing welding can be performed to form a wear-resistant layer and Coal picks undergo a heat treatment process including quenching.

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, and the process of laser quenching has high process requirements, pollution during laser quenching, difficult laser protection, and high labor intensity for workers.

The original position slides back to the original position again, and then the motor 11 drives the first L-shaped rotating arm 6 and the second L-shaped rotating arm 7 to rotate to be positioned at the top of the retractable driving device of the working frame 2 and then descend. At this time, the first conveyor belt 2 -1 Bring the material receiving seat-43 that does not load the coal pick 77 to the position of the corresponding retractable drive device, and then the first clamping frame 8 and the second clamping frame 9 descend to the position corresponding to the fifth rack 34- 1 contacts and meshes with the seventh rack 38-1, the fifth rack 34-1 and the seventh rack 38-1 drive the first worm disc 8-3 and the second worm disc 9-3 to rotate, and finally drive multiple A first clamping column 8-4 and a plurality of second clamping columns 9-4 disperse and loosen the coal pick 77, and the coal pick 77 falls on the material receiving seat 43 at the position at this time, and then the first The conveyor belt 2-1 moves and drives the material receiving seat 43 that is loaded with unprocessed coal picks 77 to move. 43 is loaded with coal picks 77 that have been laser quenched or unloaded coal picks 77. At this time, the first clamping frame 8 and the second clamping frame 9 that continue to descend repeat the above-mentioned multiple first clamping columns 8- 4 and a plurality of second clamping columns 9-4 shrink and close-up-rotate to the process of feeding frame 3, and finally realize the corresponding transfer of the coal picks 77 that have been laser quenched to the refueling seat-74, the first The second conveyor belt 53 and the third conveyor belt 56 will move the processed coal picks 77 to the first finished product recovery box 3-1 and the second finished product recovery box 3-2 accordingly, and finally the processed coal picks 77 will drop to a In the finished product recycling box 3-1 and the second finished product recycling box 3-2, the material receiving seat 43 loaded with unprocessed coal picks 77 is driven by the first conveyor belt 2-1 and waits for laser processing and quenching. When the plate-41 is located, the fourth rack 42 contacts and meshes with the outer ring gear 47, the fourth rack 42 drives the receiving tray 46 to rotate, and then the coal pick 77 to be processed rotates with the receiving tray 46, driving the column 22-1 to rotate with the receiving tray 46. The wedge-shaped inclined surface of the telescopic block 45 is in contact, and the elastic force of the sixth spring 45-1 is set to be greater than the force required to drive the mechanical arm 22 to slide on the work frame 2, and the material receiving seat 43 drives the mechanical arm 22 to slide, and finally realizes the coal loading process. The pick 77 rotates relative to the mechanical arm 22. At this time, the automatic control system controls the mechanical arm 22 to start the laser quenching work. It is set that when the material receiving seat 43 moves to the point where the fourth rack 42 is out of contact with the outer ring gear 47, the coal pick The laser quenching work of 77 has been completed, and now the material receiving seat 43 continues to advance with the coal pick 77 that has been processed, until advancing to the position of the retractable drive device on the corresponding work frame 2, set the first The clamping frame 8 and the second clamping frame 9 are located directly above the corresponding retractable driving device. At this time, the first clamping frame 8 and the second clamping frame 9 do not have coal picks 77 and are not in the process of descending. The sixth tooth rack 36-1 and the eighth tooth The contact position of strip 40-1, during the whole process, the various parts cooperate with each other to realize the movement of unprocessed coal pick 77 from the feeding seat 74 to the receiving seat 43, and the receiving seat 43 advances with the coal pick 77 to be processed , the laser quenching process is carried out during the advancing process, and the coal pick 77 is rotated relative to the mechanical arm 22 during the laser quenching process. After the laser quenching process, the processed coal pick 77 is moved to the feeding seat 74, and finally transported to The entire laser quenching process is completed in the first finished product recycling box 3-1 and the second finished product recycling box 3-2.

Beneficial effects of the present invention: the present invention isolates the laser quenching processing area, effectively avoids light pollution, waste gas pollution and other pollutants in the laser quenching process from harming the human body, greatly reduces manual labor intensity, and has a high degree of automation in the entire laser quenching process. Improve the work efficiency of laser quenching.

The above are only preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the present invention. within the scope of protection.
