Description

Technical Field

[0001] The utility model belongs to the field of heat treatment processing equipment, in particular to an automatic unhooking device for a high-temperature slow-cooling multi-purpose furnace and a conveying material vehicle. Background Art

[0002] The multi-purpose furnace includes a front chamber, a rear chamber and a slow cooling chamber arranged above the front chamber. The process of heat treatment of the workpiece is that the tooling sends the workpiece into the rear chamber for heating. After the heating is completed, the tooling returns to the front chamber and is lifted up by the elevator in the front chamber and sent to the slow cooling chamber for slow cooling. The setting of the multi-purpose furnace can complete the heat treatment process of the workpiece at one time without separate treatment, thereby improving the efficiency of heat treatment processing;

[0003] The traditional method is to use a push-pull hook to push the tooling into the back chamber, the push-pull hook is moved by a zipper, and then the push-pull hook is used to pull the tooling from the back chamber back to the front chamber, but the push-pull hook is always connected to the tooling. If the connection between the two is not released, the tooling cannot be lifted by the elevator, resulting in discontinuity in the processing flow. In order to meet the smooth operation of the above-mentioned multi-purpose furnace processing procedures, realize the automatic displacement of the tooling in the multi-purpose furnace, and enable the tooling to be pulled out of the multi-purpose furnace in time after slow cooling, and transferred to a dedicated placement area to realize automated production, an automatic unhooking device and a conveying material cart for a high-temperature slow cooling multi-purpose furnace are proposed. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings of the prior art and provide an automatic uncoupling device and a conveying cart for a high-temperature slow-cooling multi-purpose furnace, which can meet the processing requirements of the high-temperature slow-cooling multi-purpose furnace, enable the slow cooling action to be carried out, further improve the processing procedure, and have a simple and effective structure, high reliability, and ensure the completion of the uncoupling action.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: an automatic unhooking device for a high-temperature slow-cooling multi-purpose furnace, comprising a push-pull hook, a lifting mechanism and a mounting seat connected to a zipper;

[0006] The mounting seat is used to push the tooling into the rear chamber of the multi-purpose furnace;

[0007] The push-pull hook can be flipped on the mounting seat to pull the tool out of the rear chamber;

[0008] The lifting mechanism includes an axially lifted support plate, and a transition portion protruding outward is provided at the side end of the push-pull hook. The lower end of the transition portion is provided with an inclined surface matching the movement trajectory of the support plate. As the support plate is lifted, the front end of the push-pull hook is lifted up to release the connection with the tooling hook ear.

[0009] Furthermore, the lifting mechanism includes a connecting plate, and the connecting plate is linked to the supporting plate through a main driving arm and a slave driving arm.

[0010] Furthermore, the main driving arm and the slave driving arm are arranged side by side and can be rotatably connected to the connecting plate, and the end of the main driving arm and the end of the slave driving arm are hinged to the same side of the supporting plate.

[0011] Furthermore, the lifting mechanism includes a transmission shaft rotatable at the outlet of the multi-purpose furnace, and an end of the transmission shaft passes through the connecting plate and is connected to the main driving arm.

[0012] Furthermore, a driving plate is provided at the other end of the transmission shaft, and the driving plate drives the transmission shaft to swing axially by means of a driving device.

[0013] Furthermore, the push-pull hook is connected to the mounting seat via a shaft, a flipping portion linked to an external flipping device is provided at the other side end of the push-pull hook, and a through groove is provided at the center of the flipping portion.

[0014] Furthermore, a limiting portion extends outwardly from the outer side of the driving plate.

[0015] Furthermore, a clearance groove for allowing the slave driving arm to move is provided on one side of the supporting plate adjacent to the slave driving arm.

[0016] Furthermore, a friction portion is provided inside the hook body of the push-pull hook, and the front end of the hook body of the push-pull hook is inclined inward to form a force-bearing surface.

[0017] A conveying material vehicle with an automatic unhooking device for a high-temperature slow-cooling multi-purpose furnace comprises a movable vehicle body, on which an outer guide sleeve corresponding to an inner guide sleeve of the multi-purpose furnace is arranged, the push-pull hook is movable in the outer guide sleeve, and the zipper is extended and retracted from the outer guide sleeve by means of a rotatable sprocket.

[0018] The advantages and positive effects of the utility model are:

[0019] 1. Due to the adoption of the above technical solution, after the workpiece is pulled back to the front chamber, the connection between the push-pull hook and the tooling hanging ear can be released, so that the elevator can lift the tooling and send it into the slow cooling chamber, so that the slow cooling of the workpiece can be carried out smoothly without interruption in the middle, thus improving the overall processing procedure and showing the advantages of the multi-purpose furnace.

[0020] 2. The utility model has a compact structure and is easy to install. It will not hinder the normal operation of other components. It relies on the cylinder to drive the drive plate, saving the floor space of the drive device. The limiter extended on the drive plate can limit the rotation angle of the transmission shaft.

[0021] The pallet is linked to the connecting plate by the main driving arm and the slave driving arm, so that the pallet can be lifted axially. The lifting trajectory of the pallet matches the inclined surface of the transition part on the push-pull hook, so as to lift the hook body at the front end of the push-pull hook and release the connection with the tooling hanging ear. The operation process of the lifting mechanism is faster, which shortens the waiting time and enables the processing to proceed smoothly. The main driving arm and the slave driving arm are connected at two points to ensure the smooth lifting of the pallet and avoid deviation.

[0022] 3. The setting of the conveyor car further improves the process from heat treatment of tooling to centralized placement of finished products, which facilitates centralized management and realizes automated production. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The utility model is further described below in conjunction with embodiments and drawings.

[0038] like Figures 1 to 6 As shown, this embodiment provides an automatic unhooking device for a high-temperature slow-cooling multi-purpose furnace, comprising a push-pull hook 8, a lifting mechanism and a mounting seat 9 connected to a zipper;

[0039] A push platform 91 protrudes outward from the front end of the mounting seat 9, and the tooling is pushed into the rear chamber of the multi-purpose furnace by the drive of the zipper to heat the workpiece;

[0040] The push-pull hook 8 is rotatably connected to the mounting seat 9 through an axis, and a flipping portion 8 is provided at the side end of the push-pull hook 8. The flipping portion 8 is linked with an external flipping device so that the push-pull hook can flip forward and backward. When the push-pull hook 8 flips forward, it is used to pull the tooling out of the rear chamber. A horizontal through slot is provided through the center of the flipping portion 8. In this embodiment, the flipping device includes a rotatable flipping shaft 11, and the end of the flipping shaft 11 is in an "I" shape, and the "I"-shaped protrusion matches the through slot;

[0041] The lifting mechanism is arranged at the entrance of the multi-purpose furnace, including an axially lifted support plate 7, and a transition portion 81 protrudes outward from the side end of the push-pull hook 8 adjacent to the support plate 7. The lower end of the transition portion 81 is provided with an inclined surface matching the movement trajectory of the support plate 7, that is, the rear end portion of the lower end surface of the transition portion 81 gradually tilts upward to form a notch. When the support plate 7 moves forward and upward and is lifted, the front end of the push-pull hook 8 is lifted up through the transition portion 81 to release the connection with the tooling hanging ear.

[0042] The lifting mechanism includes a connecting plate 4 fixed in the multi-purpose furnace, and the support plate 7 and the connecting plate 4 are linked by a main driving arm 5 and a slave driving arm 6 arranged side by side. Specifically, one end of the main driving arm 5 is rotatably connected to the connecting plate 4, and the other end is rotatably connected to one side of the support plate 7 through an axis. One end of the slave driving arm 6 is rotatably connected to the connecting plate 4 on one side of the main driving arm 5 through a connecting shaft 61, and the other end is rotatably connected to one side of the support plate 7 through an axis. The axis connecting the two shaft centers in the main driving arm 5 is parallel to the axis connecting the two shaft centers in the slave driving arm 6.

[0043] The lifting mechanism includes a rotatable transmission shaft 3, the end of the transmission shaft passes through the connecting plate 4 and is connected to the main driving arm 5, which has driven the rotation of the main driving arm 5. A driving plate 2 is provided at the other end of the transmission shaft 3. The driving plate 2 drives the transmission shaft 3 to swing axially by means of a driving device, and has driven the lifting and lowering of the support plate 7. In order to limit the rotation angle of the transmission shaft 3, a limiting portion 21 is extended outwardly from the outside of the driving plate 21. In this embodiment, the driving device adopts a cylinder, and the cylinder is hinged to the outer wall of the multi-purpose furnace. The push rod of the cylinder is hinged to the driving plate 2. In another embodiment, a sprocket can also be provided at the end of the transmission shaft 3, and the rotation is realized by the engagement of the chain and the sprocket.

[0044] In order to enhance the friction of the hook body in the push-pull hook 8, a friction portion 82 is provided on the inner side of the hook body of the push-pull hook 8. In the present embodiment, the friction portion 82 is composed of a plurality of parallel grooves, so that the inner side of the hook body is corrugated. The front end of the hook body of the push-pull hook 8 is inclined inward to form a force-bearing surface, which is convenient for connection with the tooling hook ear.

[0045] A conveying vehicle with an automatic unhooking device for a high-temperature slow-cooling multi-purpose furnace comprises a movable vehicle body 10. In order to guide the moving path of a push-pull hook 8 in the multi-purpose furnace, an inner guide sleeve is arranged in the inner cavity of the front chamber of the multi-purpose furnace, and an outer guide sleeve 101 corresponding to the inner guide sleeve is arranged on the vehicle body 10. The push-pull hook 8 can move in the outer guide sleeve 101.

[0046] The zipper achieves telescopic movement in the outer guide sleeve 101 by rotating the sprocket 102 on the body 10. Specifically, the sprocket 102 is driven to rotate by the reducer, and the mounting seat 9 is connected to the head end of the zipper. The zipper is meshed with the sprocket 102. The zipper is pushed forward or pulled backward by the rotation of the sprocket 102 to achieve the displacement of the push-pull hook 8. In order to further facilitate the tooling to be pushed, rollers are provided on both sides of the body 10 that are in contact with the tooling.

[0047] The turning device is disposed on the outer side of the vehicle body 10 adjacent to the sprocket 102 .

[0048] In this embodiment, a guide rail is provided on the workshop floor to guide the movement of the vehicle body 10, and a slider connected to the guide rail is provided at the lower end of the vehicle body 10 to realize the movement of the vehicle body 10. In another embodiment, rollers can also be provided at the lower end of the vehicle body 10 to realize the movement.

[0049] The working process of this example:

[0050] After the workpieces are stacked on the tooling, the tooling is placed on the body 10 of the conveyor vehicle;

[0051] The zipper is driven by the sprocket 102 on the body and pushed forward, the initial position of the push-pull hook 8 is flipped backward, the push platform 91 of the mounting seat 9 is exposed, facing the tooling, the mounting seat 9 is driven forward by the zipper, the tooling is entered into the front chamber from the entrance of the multi-purpose furnace, and then pushed into the rear chamber for heating;

[0052] The rear sprocket 102 rotates to pull the zipper back, and the zipper drives the mounting seat 9 to move back. The flipping device on the vehicle body 10 rotates in coordination with the through slot of the flipping portion 83, driving the push-pull hook 8 to flip forward, and a placement cavity is formed between the push platform 91 and the hook body of the push-pull hook 8.

[0053] When the rear chamber of the multi-purpose furnace is heated, the zipper drives the mounting seat 9 to move forward toward the tooling again. Because the front end of the push-pull hook 8 is inclined inward, when the push-pull hook 8 continues to move forward and touches the hanging ear of the tooling, the inclined force-bearing surface causes the push-pull hook 8 to lift up and hook with the hanging ear of the tooling, completing the connection with the tooling. The push-pull hook 8 pulls the tooling and brings it into the front chamber of the multi-purpose furnace;

[0054] When the push-pull hook 8 moves to the entrance of the multi-purpose furnace, the cylinder drives the driving plate 2 to rotate the transmission shaft 3. At this time, the main driving arm 5 drives the support plate 7 to lift axially, and the slave driving arm 6 is linked with the support plate 7 to ensure the level of the upper end surface of the support plate 7. Through the transition of the inclined surface of the transition part 81, the hook body of the push-pull hook 8 is lifted up, and the restriction on the tooling ear is released. The tooling relies on the elevator in the front room of the multi-purpose furnace to rise and enter the slow cooling chamber.

[0055] The tooling that has completed slow cooling is lowered back to the front chamber of the multi-purpose furnace. After the push-pull hook 8 is pushed forward and hooked with the tooling hanging ear, it is pulled backward to pull the tooling from the entrance of the multi-purpose furnace to the car body 10. The operator can move the car body 10 to transport the processed workpiece to the desired location.

[0056] The above describes one or more embodiments of the utility model in detail, but the above contents are only preferred embodiments of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model shall still fall within the scope of the patent coverage of the utility model.
