Description

Technical Field

[0001] This utility model relates to the field of quenching technology for wear-resistant castings, specifically a quenching device for wear-resistant castings. Background Technology

[0002] Quenching is a heat treatment process that involves heating a metal material to a certain temperature and then rapidly cooling it to achieve high surface hardness and wear resistance. Quenching is commonly used in the manufacture of industrial parts such as mechanical parts, cutting tools, molds, and gears.

[0003] For example, a quenching device for wear-resistant castings, with announcement number "CN209481721U", involves sliding the processed wear-resistant castings from a slide rail to the side of a quenching tank. Then, an electro-hydraulic cylinder is activated to pour the wear-resistant castings from a pallet into the quenching tank. After quenching, a hoist is activated to lift the quenched castings, separating them from the coolant in the quenching tank for oil draining. However, this quenching device, after lifting the quenched castings, places them above the quenching tank. Since wear-resistant castings are generally quite heavy, this position above the tank makes unloading difficult for workers, requiring more time and reducing work efficiency. Utility Model Content

[0004] The purpose of this utility model is to solve the problem of the wear-resistant casting quenching device. After the wear-resistant casting is lifted by the hoist, it is located above the quenching tank. Since the wear-resistant casting is usually quite heavy, it is not conducive to the unloading operation by the workers. This results in the workers having to spend a lot of time unloading the casting, thus reducing work efficiency. Therefore, this utility model proposes a wear-resistant casting quenching device.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A quenching device for wear-resistant castings is designed, including a base plate, a quenching box fixedly connected to the front middle of the base plate, a first outer shell fixedly connected to the middle of the base plate, a rotating mechanism provided inside the first outer shell, a bending plate provided above the rotating mechanism, a first cylinder fixedly connected to the upper end of the outer wall of the bending plate, a second outer shell fixedly connected to the output end of the first cylinder, and a clamping mechanism provided inside the second outer shell.

[0007] Preferably, a filter box is placed in a limiting groove machined on the right side of the base plate, and the outer wall of the filter box is symmetrically machined with slots.

[0008] Preferably, the rotating mechanism includes an electric push rod and a positioning block. The output end of the electric push rod is fixedly connected to a rack. The outer wall of the rack meshes with a gear. The rotation shaft of the gear is rotatably connected to the first housing through a bearing. The protruding inner wall of the rack is slidably connected to a first limiting rod. Both ends of the first limiting rod are fixedly connected to the first housing. The outer wall of the positioning block is fixedly connected to the first housing.

[0009] Preferably, the rotating shaft of the gear is fixedly connected to a bent plate, and the right end of the electric push rod is fixedly connected to a protrusion on the base plate.

[0010] Preferably, the clamping mechanism includes a second cylinder, the output end of which is fixedly connected to a horizontal plate. Both ends of the horizontal plate are movably connected to a rotating rod via pins. The ends of the rotating rods are movably connected to a sliding plate via pins. The inner wall of the sliding plate is slidably connected to two second limiting rods. One end of each of the multiple second limiting rods is fixedly connected to a second outer shell.

[0011] Preferably, the lower end of the slide plate is machined with a locking block that engages with a slot, and the end of the second cylinder is fixedly connected to a protrusion on the second housing.

[0012] The wear-resistant casting quenching device proposed in this utility model has the following advantages: through the cooperation of the rotating mechanism and the clamping mechanism, the output end of the electric push rod continues to retract, driving the rack to continue moving to the right. When the output end of the electric push rod retracts to its limit position, the rack moves to its limit position to the right, and the bending plate rotates to the left side of the bottom plate directly above the marked line (e.g., Figure 1 The worker can place the trolley at the marked position, then activate the output end of the multi-stage hydraulic cylinder to extend and move the filter box containing the hardened wear-resistant casting downwards. Once the filter box contacts the trolley surface, stop the multi-stage hydraulic cylinder, and then activate the pneumatic cylinder (e.g., ...). Figure 1 The cylinder's output end extends, causing the horizontal plate to move downwards. This, in turn, causes the rotating rods on both sides to rotate in reverse around the pin of the horizontal plate, thus moving the slide plate outwards. As the slide plate moves outwards, the inner protrusion of the slide plate disengages from the slot of the filter box. Restarting the multi-stage hydraulic cylinder retracts the output end, enabling the unloading of the quenched wear-resistant castings. By rotating the clamping mechanism to a position not above the quenching box, and ensuring that the clamping mechanism can place the filter box in the designated position, rapid unloading is achieved, saving unloading time and improving work efficiency.

[0020] The present invention will be further described below with reference to the accompanying drawings:

[0021] See attached document Figure 1-6 :

[0022] In this embodiment, a wear-resistant casting quenching device includes a base plate 1, a quenching box 6 fixedly connected to the front center of the base plate 1, a first outer shell 2 fixedly connected to the center of the base plate 1, a rotating mechanism 3 provided inside the first outer shell 2, a bending plate 7 provided above the rotating mechanism 3, the movement of the rotating mechanism 3 can drive the rotating plate 7 to move, a multi-stage hydraulic cylinder 8 fixedly connected to the upper end of the outer wall of the bending plate 7, a second outer shell 10 fixedly connected to the output end of the multi-stage hydraulic cylinder 8, the extension and retraction of the output end of the multi-stage hydraulic cylinder 8 drives the second outer shell 10 to move, a clamping mechanism 9 provided inside the second outer shell 10, the movement of the second outer shell 10 drives the clamping mechanism 9 to move, a filter box 4 is placed in a limiting groove machined on the right side of the base plate 1, a marking line is drawn on the left side of the base plate 1 to mark the lowering position of the filter box 4 to facilitate the unloading operation of the workers, and slots 5 are symmetrically machined on the outer wall of the filter box 4.

[0023] See attached document Figure 1-2 and 5-6:

[0024] The rotating mechanism 3 includes an electric push rod 301 and a positioning block 302. A rack 303 is fixedly connected to the output end of the electric push rod 301. The extension and retraction of the output end of the electric push rod 301 drives the rack 303 to move. The outer wall of the rack 303 meshes with a gear 304. The movement of the rack 303 drives the gear 304 to rotate. The rotation shaft of the gear 304 is rotatably connected to the first housing 2 via a bearing. The protruding inner wall of the rack 303 is slidably connected to a first limiting rod 305. The rack 303 is limited by the first limiting rod 305, causing it to move... The movement is more stable. Both ends of the first limiting rod 305 are fixedly connected to the first outer shell 2. The outer wall of the positioning block 302 is fixedly connected to the first outer shell 2. The positioning block 302 is used to position the electric push rod 301. When the output end of the electric push rod 301 is pressed against the positioning block 302, the distance that the rack 303 moves is just enough to drive the gear 304 to rotate 180 degrees. The rotating shaft of the gear 304 is fixedly connected to the bending plate 7. The rotation of the gear 304 drives the bending plate 7 to rotate. The right end of the electric push rod 301 is fixedly connected to the protrusion of the base plate 1.

[0025] See attached document Figure 1-4 :

[0026] The clamping mechanism 9 includes a cylinder 901. A horizontal plate 902 is fixedly connected to the output end of the cylinder 901. The extension and retraction of the output end of the cylinder 901 drives the horizontal plate 902 to move. Both ends of the horizontal plate 902 are movably connected to the rotating rod 903 through pins. The movement of the horizontal plate 902 drives the rotating rod 903 to move around the lower part of the plate as the rotation center. The ends of the rotating rod 903 are movably connected to the slide plate 904 through pins. The movement of the rotating rod 903 drives the slide plate 904 to move. The inner wall of the slide plate 904 is slidably connected to two second limiting rods 905. The slide plate 904 is limited to horizontal movement by the second limiting rods 905. One end of each of the second limiting rods 905 is fixedly connected to the second outer shell 10. The locking block machined at the lower end of the slide plate 905 engages with the locking groove 5. The slide plate 905 can be locked in the locking groove 5, thereby driving the filter box 4 to move. The end of the cylinder 901 is fixedly connected to the protrusion of the second outer shell 10.

[0027] Working principle:

[0028] When quenching wear-resistant castings.

[0029] Preparation:

[0030] The staff placed filter box 4 into the positioning slot on the right side of the bottom plate 1 (e.g.) Figure 1 Then, the heated wear-resistant casting is placed in the filter box 4. The filter box 4 has a through hole at the bottom for filtering the coolant, and coolant is added to the quenching box 6.

[0031] Quenching process:

[0032] Start multi-stage hydraulic cylinder 8 (e.g.) Figure 1The output end of the multi-stage hydraulic cylinder 8 extends, driving the second housing 10 and the clamping mechanism 9 to move downwards. After the clamping mechanism 9 moves downwards to its limit distance, the two sliding plates 904 are on both sides of the filter box 4. Then, the cylinder 901 is activated (as shown in the image). Figure 3 The output end of cylinder 902 retracts, causing the horizontal plate 902 to move upward. The upward movement of the horizontal plate 902 causes the rotating rod 903 to rotate clockwise around the pins at both ends of the horizontal plate 902, thereby causing the slide plate 904 to move inward. The movement of the slide plate 904 is controlled by the horizontal movement of the second limit rod 905. When the slide plate 904 moves inward, the protrusion on the inner side of the slide plate 904 extends into the slot 5. When the outer wall of the slide plate 904 abuts against the inner wall of the slot 5, cylinder 901 stops (e.g.). Figure 4 Then restart the output end of the multi-stage hydraulic cylinder 8 and retract it to the limit distance, which drives the clamping mechanism 9 to move upward, thereby driving the filter box 4 containing wear-resistant castings to move upward to the limit distance;

[0033] At this time, the output end of the electric push rod 301 is in contact with the positioning block 302. Then, the electric push rod 301 is started, and the output end of the electric push rod 301 retracts, causing the rack 303 to move to the right. The rack 303 moves to the right, causing the gear 304 to rotate clockwise. The rotation of the rack 304 causes the bending plate 7 to rotate. The rotation of the bending plate 7 causes the multi-stage hydraulic cylinder 8 to rotate, thereby causing the filter box 4 containing the wear-resistant casting to rotate. Observe when the filter box 4 containing the wear-resistant casting rotates to above the quenching box 6. Since the quenching box 6 is much larger than the filter box 4, it does not need to be too precise. The filter box 4 can enter the quenching box 6. Then, the multi-stage hydraulic cylinder 8 is started (e.g., Figure 1 The output end of the multi-stage hydraulic cylinder 8 extends and drives the filter box 4 containing the wear-resistant casting to move downward and enter the quenching box 6. When the coolant in the quenching box 6 reaches the filter box 4, the heated wear-resistant casting can be quenched. After quenching, the multi-stage hydraulic cylinder 8 is activated and the output end of the multi-stage hydraulic cylinder 8 retracts to the limit position, thereby moving the quenched wear-resistant casting filter box 4 upward to the limit position. The coolant is discharged from the lower end through hole of the filter box 4 to avoid waste, thus realizing the quenching of the wear-resistant casting.

[0034] After filtration, restart the electric actuator 301 (e.g.) Figure 5 The output end of the electric actuator 301 continues to retract, driving the rack 303 to continue moving to the right. When the output end of the electric actuator 301 retracts to its limit position (e.g. Figure 5 When rack 303 moves to its rightmost position, bending plate 7 rotates to the left side of bottom plate 1, directly above the marked line (e.g.) Figure 1 The worker can place the trolley at the marked position, then activate the output end of the multi-stage hydraulic cylinder 8 to extend and move the filter box 4, which contains the hardened wear-resistant castings, downwards. Once the filter box 4 contacts the surface of the trolley, stop the multi-stage hydraulic cylinder 8, and then activate cylinder 901 (e.g., ...). Figure 3The output end of cylinder 901 extends, causing the horizontal plate 902 to move downwards, which in turn causes the rotating rods 903 on both sides to rotate in reverse around the pin of the horizontal plate 902, thereby causing the slide plate 904 to move outwards. When the slide plate 904 moves outwards, the inner protrusion of the slide plate 904 disengages from the slot 5 of the filter box 4. Restarting the multi-stage hydraulic cylinder 8 retracts the output end, thus realizing the unloading of the quenched wear-resistant casting.

[0035] When further processing is required, the output end of the electric actuator 301 extends (e.g., Figure 5 This causes the rack 303 to move to the left. When the output end of the electric push rod 301 abuts against the positioning block 302, the rack 303 moves to the left a distance that can drive the gear 304 to rotate 180 degrees, thereby driving the bending plate 7 to rotate 180 degrees, thereby driving the clamping mechanism 9 to rotate directly above the positioning groove machined on the right side of the bottom plate 1. Then repeat the above operation. After all is completed, turn off all power.

[0036] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
