Description

Technical Field

[0001] This utility model belongs to the field of quenching equipment technology, specifically a quenching mechanism for metal parts. Background Technology

[0002] Metal quenching is a heat treatment process that improves the hardness and strength of metals through rapid cooling. The process involves heating the metal to above the critical temperature (usually 750-1300℃), holding it at that temperature to austenitize it, and then rapidly immersing it in a quenching medium such as water, oil, or polymer. This rapid cooling inhibits the transformation of austenite to pearlite, promoting the formation of a high-hardness martensite structure. Although the hardness of the quenched metal is significantly improved, its brittleness increases, often requiring tempering to adjust the toughness and balance internal stress. It is widely used in the strengthening treatment of key mechanical components such as cutting tools, molds, and gears, and is a core process for improving wear resistance and service life.

[0003] Metal quenching requires the use of a quenching furnace. Traditional quenching furnaces have side-opening doors that require a large operating space. Furthermore, the side-opening doors can easily obstruct workers' work. Therefore, improvements are needed to address these issues. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: a metal parts quenching mechanism, comprising a quenching furnace, an upper furnace door, and a lower furnace door. The upper and lower furnace doors are connected by several 180-degree hinges and combined to form a complete furnace door that is sealed at the furnace opening. Telescopic cylinders are rotatably installed on the upper part of both sides of the quenching furnace. The telescopic ends of the two telescopic cylinders are rotatably connected to the upper part of the two end faces of the upper furnace door, respectively. Inclined blocks are fixedly installed on the top of both sides of the quenching furnace. Fixed plates located below the inclined blocks are fixedly installed on both sides of the quenching furnace. Inclined grooves are formed on the surface of the inclined blocks. Linkage grooves are formed on the surface of the fixed plates. Connecting rods are connected between the upper part of the two end faces of the upper furnace door and the two inclined grooves, respectively. Telescopic connecting rods are connected between the lower part of the two end faces of the lower furnace door and the two linkage grooves, respectively.

[0005] Preferably, one end of each of the two connecting rods is fixedly installed with a circular slider A that is slidably installed inside the inclined slide groove, and the end of each connecting rod away from the circular slider A is rotatably connected to the upper furnace door.

[0006] Preferably, both telescopic connecting rods include telescopic connecting rods, both T-shaped insert rods are rotatably connected to the lower furnace door, and the T-shaped insert rods are movably inserted into the inside of the insert tube. A circular slider B, which is slidably installed inside the connecting groove, is fixedly installed on one side of the insert tube.

[0007] Preferably, gears are fixedly installed at the ends of the upper and lower furnace doors that are close to each other. Two adjacent gears of the upper and lower furnace doors are meshed together, so that when the upper furnace door rotates, it can drive the lower furnace door to rotate synchronously, thereby causing the upper and lower furnace doors to flip and fold.

[0008] Preferably, each of the 180-degree hinges includes a pair of curved plate connecting blocks. The middle of each pair of curved plate connecting blocks is symmetrically connected by a connecting shaft. The opposite ends of the upper furnace door and the lower furnace door are symmetrically provided with holes and slots at equal distances. A connecting slot is provided at the end of each hole and slot. An I-shaped slider is slidably installed inside each hole and slot. The two ends of each pair of curved plate connecting blocks are rotatably connected to two oppositely arranged I-shaped sliders and two connecting slots, so that the upper furnace door can stably perform a 180-degree flip-folding operation.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: the furnace door of the quenching mechanism for metal parts is an upward folding structure. This upward folding structure of the furnace door can effectively reduce the operating space required for opening and closing the furnace door, and also avoid the open furnace door from hindering the workers' work. At the same time, the upward folding structure of the furnace door is simple in design, easy to use, and the adjustment and upward folding operation are stable and reliable.

[0018] Depend on Figures 1 to 4 The present invention includes a quenching furnace 1, an upper furnace door 2, and a lower furnace door 3. The upper furnace door 2 and the lower furnace door 3 are connected by several 180-degree hinges 4 and assembled into a complete furnace door that is sealed at the furnace opening of the quenching furnace 1. Telescopic cylinders 5 are rotatably installed on the upper part of both sides of the quenching furnace 1. The telescopic ends of the two telescopic cylinders 5 are rotatably connected to the upper part of the two end faces of the upper furnace door 2, respectively. Inclined blocks 6 are fixedly installed on the top of both sides of the quenching furnace 1. Fixed plates 7 located below the inclined blocks 6 are fixedly installed on both sides of the quenching furnace 1. The surface of the inclined blocks 6 is... An inclined slide groove 8 is provided, and a connecting slide groove 9 is provided on the surface of the fixed plate 7. The connecting slide groove 9 is composed of a vertical groove and an inclined groove. The inclined groove is located at the bottom of the vertical groove, and the inclined groove is parallel to the inclined slide groove 8 and has the same length. Through the setting of the inclined slide groove 8 and the inclined groove, the upper furnace door 2 and the lower furnace door 3 can tightly seal the furnace opening of the quenching furnace 1 when they move down. The upper part of each end face of the upper furnace door 2 is connected to the two inclined slide grooves 8 with connecting rods 10, and the lower part of each end face of the lower furnace door 3 is connected to the two connecting slide grooves 9 with telescopic connecting rods 11.

[0019] One end of each of the two connecting rods 10 is fixedly installed with a circular slider A12 that is slidably installed inside the inclined slide groove 8. The ends of the two connecting rods 10 away from the circular slider A12 are rotatably connected to the upper furnace door 2. Both telescopic connecting rods 11 include telescopic connecting rods 11. Both T-shaped insert rods 13 are rotatably connected to the lower furnace door 3, and the T-shaped insert rods 13 are movably inserted into the inside of the insert tube 14. One side of the insert tube 14 is fixedly installed with a circular slider B16 that is slidably installed inside the linkage slide groove 9.

[0020] Gears 17 are fixedly installed at the ends of the upper furnace door 2 and the lower furnace door 3 that are close to each other. The two adjacent gears 17 of the upper furnace door 2 and the lower furnace door 3 are meshed and connected, so that when the upper furnace door 2 rotates, it can drive the lower furnace door 3 to rotate synchronously, so that the upper furnace door 2 and the lower furnace door 3 can be flipped and folded.

[0021] Each 180-degree hinge 4 includes a pair of curved plate connecting blocks 21. The middle of each pair of curved plate connecting blocks 21 is symmetrically connected by a connecting shaft 22. The opposite ends of the upper furnace door 2 and the lower furnace door 3 are symmetrically provided with holes and slots 18 at equal distances. The ends of the holes and slots 18 are provided with connecting slots 19. I-beam sliders 20 are slidably installed inside the holes and slots 18.

[0022] Specifically, when it is necessary to view the attached diagram Figure 1 When the upper furnace door 2 and lower furnace door 3 are moved upward and flipped and folded, the two telescopic cylinders 5 are activated simultaneously to extend, which pushes the upper furnace door 2 to move. At the same time, the connecting rod 10, the circular slider A12 and the inclined slide 8 will cause the upper furnace door 2 to drive the lower furnace door 3 to tilt and move upward. The tilting and upward movement of the lower furnace door 3 will cause the T-shaped insert rod 13 to move out inside the insert tube 14. Finally, the T-shaped insert rod 13 will pull the insert tube 14 and the circular slider B16 to move, thereby causing the circular slider B16 to move upward inside the linkage slide 9.

[0023] Then, by limiting the circular slider A12 through the inclined slide groove 8, the two extended telescopic cylinders 5 will push the upper furnace door 2 to rotate. The upper furnace door 2 will cause the lower furnace door 3 to flip through the fixed meshing gear 17. Finally, the lower furnace door 3 will be flipped 180 degrees through several 180-degree hinges 4 and folded at the bottom of the upper furnace door 2 that has been rotated 180 degrees.

[0024] The rotation of the upper furnace door 2 and the lower furnace door 3 will cause the curved plate connecting block 21 to rotate and move. The rotation and movement of the curved plate connecting block 21 will drive the I-beam slider 20 to move inside the slot 18 (as shown in the attached figure). Figure 4 (As shown).

[0025] The quenching furnace door of this metal parts quenching mechanism has an upward folding structure. This upward folding structure can effectively reduce the operating space required for opening and closing the furnace door, and also avoid the open furnace door from hindering the workers' work. At the same time, the upward folding structure of the quenching furnace door has a simple design, is easy to use, and the adjustment and upward folding operation are stable and reliable. Its performance can meet the usage requirements of metal quenching furnaces.
