Description

Technical Field

[0001] The invention relates to the technical field of quenching processing, and in particular to a precision-cut chain track segment quenching system. Background Art

[0002] The track link is produced and processed by hot die forging. After the die forged track link completes the precision cutting process, it is induction hardened by the heating and tempering treatment line to complete the tread heat treatment production of the track link and improve the wear resistance and service life of the track link. The precision-cut track link is transported to the medium-frequency induction heating zone by the horizontal conveyor track for heating. After water spray cooling in the spray zone and re-tempering heating in the tempering zone, the quenching of the track link is completed. The track link is directly placed on the surface of the conveyor track and passes through different areas inside the medium frequency induction heating zone on the track. Due to its own function, the track link is an irregular structure with obvious uneven thickness and raised and recessed parts. The flat tread part of the track link moving in the medium frequency induction heating zone is obviously treated by the induction heating part. The uneven thickness, recessed parts and edge parts of the track link are at different distances from the induction heating part. At the same time, due to the regional interval distribution of the special-shaped areas, the induction heat treatment of each area of ​​the track link is prone to local surface overheating and insufficient heating, resulting in incomplete heat treatment of the track link directly transported from the medium frequency induction heating zone, and unable to effectively perform targeted fixed-point heat treatment on the various special-shaped areas of the track link tread, so that directly entering the spray area for water spray cooling is prone to cracking of the track link workpiece, affecting the quenching effect of the track link and affecting the operation efficiency. Summary of the invention

[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a precision-cut track segment quenching system, which supports the track segment that escapes from the medium frequency heating zone from below and positions the track segment to an inclined state by setting a lower end support beam and an upper end support beam, and the special-shaped area heat treatment module is fixed at the outside of the track segment, and the upper contoured heat pipe and the lower contoured heat pipe are molded on the surface of the track segment one above and one below, and the four middle groove heat pipes are close to the special-shaped groove wall of the middle groove at the corresponding position of the track segment, effectively close to and cover the various special-shaped areas of the track segment tread that are regionally spaced and distributed, and the various special-shaped areas of the track segment tread are targeted and fixed-point heat treated.

After the chain track segment is released from the medium frequency heating zone 1, the lower end joist 63 and the upper end joist 64 support the chain track segment from below, which can position the chain track segment and shape the chain track segment to an inclined state, so that the upper contoured heat pipe 51, the lower contoured heat pipe 52 and the middle groove heat pipe 53 can be effectively fixed in the designated area of ​​the chain track segment tread.

[0024] An outer block 21 is provided on the outer side of the circulating conveying mechanism 2 , and the bracket 4 , the special-shaped area heat treatment module 5 and the fixed-point constraint module 6 are all located on the inner side of the outer block 21 , providing a safe working space for the special-shaped area heat treatment module 5 .

[0025] The immersion module 7 is arranged on the surface of the linear conveying mechanism 3. The immersion module 7 is composed of a profiling shell 71 and a water guide shell 72. The profiling shell 71 is fixedly connected to the inside of the water guide shell 72. The water guide shell 72 is fixedly connected to the surface of the conveying part of the linear conveying mechanism 3. The immersion module 7 is stably connected to the linear conveying mechanism 3 to ensure that the linear conveying mechanism 3 stably conveys the immersion module 7 and the internal chain track segments. The chain track segments heat-treated by the profiled area heat treatment module 5 enter the profiling shell 71. The profiling shell 71 is used to constrain the chain track segments. The water guide shell 72 can guide and release cooling water into the profiling shell 71, so that the chain track segments are immersed in the cooling water. It can effectively constrain the chain track segments after auxiliary heating at fixed points and guide the released cooling water to contact various areas of the chain track segment tread for a long time, thereby improving the cooling effect of the chain track segments.

[0026] The track segment passing through the intermediate frequency heating zone 1 is released from the intermediate frequency heating zone 1, and the lower end support beam 63 that has changed its position and positioned cooperates with the upper end support beam 64 to support the track segment from below and position the track segment to an inclined state, effectively constraining the track segment at a fixed point and adjusting the track segment to a state that is adapted to the special-shaped zone heat treatment module 5. The special-shaped zone heat treatment module 5 is fixed at the outer side of the track segment, and the upper profile heat pipe 51 and the lower profile heat pipe 52 are molded on the surface of the track segment one above and one below. The four middle groove heat pipes 53 are close to the special-shaped groove wall of the middle groove at the corresponding position of the track segment, effectively close to and cover the various special-shaped areas of the track segment tread that are distributed regionally at intervals, and can effectively perform targeted fixed-point heat treatment on the various special-shaped areas of the track segment tread, thereby improving the induction heat treatment effect of various areas of the track segment tread. After targeted heat treatment of various shaped areas of the track segment tread, the lower end support beam 63 is controlled by the steering drive 61 to change state, so that the top of the lower end support beam 63 is separated from the track segment. Under the control of the changed state of the lower end support beam 63, the track segment is separated from the fixed point constraint module 6 and enters the inside of the contour shell 71. The immersion module 7 fixedly constrains the track segment after auxiliary heating, so that the track segment is always kept in the contour shell 71 with water stored inside during water spray cooling. The water guide shell 72 guides and releases the sprayed cooling water into the contour shell 71, fills the contour shell 71 and allows the track segment to enter the cooling water, so that the track segment is simultaneously subjected to water spray cooling and immersion cooling, which can effectively complete the cooling operation of various shaped areas of the track segment tread, thereby improving the quenching effect of the track segment and improving the operation efficiency.

[0027] The working principle of the present invention is as follows: the intermediate frequency heating zone 1 performs heating treatment on the track segment. After the track segment passes through the intermediate frequency heating zone 1 and escapes from the intermediate frequency heating zone 1, the lower end support beam 63 and the upper end support beam 64 support the track segment from below and position the track segment to an inclined state. During the state change process of the track segment, the upper profiled heat pipe 51 is approached, and the upper profiled heat pipe 51 and the lower profiled heat pipe 52 are molded on the surface of the track segment one above and one below. The four middle groove heat pipes 53 are close to the special-shaped groove wall of the middle groove at the corresponding position of the track segment, close to and cover the various special-shaped areas of the track segment tread that are distributed at intervals in the region, and the various special-shaped areas of the track segment tread are subjected to targeted fixed-point heat treatment, and the cyclic conveying Mechanism 2 conveys the heat treatment module 5 in the special-shaped area and the track segment to move toward the linear conveying mechanism 3. Under the control of the lower end support beam 63 which changes its state, the track segment escapes from the fixed-point constraint module 6 and enters into the contour shell 71. After the fixed-point constraint auxiliary heating, the linear conveying mechanism 3 passes through the liquid spraying area to spray water cooling the track segment from the outside. The water guide shell 72 guides and releases part of the sprayed cooling water into the contour shell 71, so that the track segment is immersed in the cooling water. The track segment is subjected to water spray cooling and immersion cooling at the same time. The cooled track segment escapes outward from the contour shell 71 which changes its position following the linear conveying mechanism 3, and the quenching of the track segment is completed.
