Description

Technical Field

[0001] The present invention relates to the technical field of material handling devices for heating systems, and in particular to a handling device for a material frame. Background Art

[0002] In recent years, my country's industry has developed rapidly. Industries such as metallurgy, machinery, petroleum, and chemicals have attached increasing importance to the production of heating furnaces, and have conducted in-depth research on control technology, combustion technology, heating process, heating quality, energy conservation and environmental protection, and other aspects. As we all know, when a heating furnace is heat treated, the loading and unloading processes are all manually produced by the operator, and the labor intensity is very high. It is a high-temperature operation when it is unloaded from the furnace, especially in summer, when the climate is hot, and the heat treatment unloading and quenching process is required to be completed in a relatively short time. The existing processing steps are to manually take the metal materials out of the heat treatment furnace to the furnace door, and then use a quenching basket to hang them into the quenching medium for quenching treatment. With the advancement of production processes and production technologies in the manufacturing industry, especially the widespread application of automation and intelligence in industrial production, automation solutions represented by robots have improved the working environment of operators in the heating system and improved production efficiency and production quality. In view of this, the applicant filed this application. Summary of the invention

[0003] The invention discloses a transport device for a material frame. With the transport device, heat treatment of materials in the material frame can be completed, thus solving the problem of overly complicated transport process.

[0004] The present invention adopts the following scheme:

[0005] A transport device for a material frame, used for heat treating materials placed in the material frame, comprising: a base, a clamping plate for a manipulator to clamp, a front fork mechanism for transporting the material frame into and out of a heating furnace, and a conveying chain device for transporting the material frame into and out of a quenching tank, wherein the clamping plate is fixed on the base, the front fork mechanism is fixed on the front end of the base, and the conveying chain device is fixed on the base.

[0006] The material frame includes a receiving cavity, a lifting ring and a handle, wherein the receiving cavity is used to place the material to be processed, the lifting ring is used to cooperate with the transport device to transport the material frame into and out of the heating furnace, and the handle is used to cooperate with the transport device to transport the material frame into and out of the quenching tank;

[0007] The front fork mechanism comprises at least two clamping frames, and the clamping frames are provided with at least two grooves, which are respectively provided at the front and rear ends, and are used to cooperate with the lifting ring to fork the material frame to be transported into and out of the heating furnace;

[0008] The conveying chain device includes a driving mechanism, a chain transmission mechanism and a hook, wherein the hook is connected to the chain end of the chain transmission mechanism, and the hook is used to lift the handle. The driving mechanism drives the chain transmission mechanism to rotate so that the hook descends or rises to transport the material frame into or out of the quenching tank.

[0009] As a further improvement, the hook includes a hook head, a guide member and a self-locking member. The guide member is arranged at the top of the hook and connected to the chain. The self-locking member is hinged between the guide member and the hook head. The self-locking member and the hook head can be in a closed or open state under the action of force.

[0010] As a further improvement, the base is provided with a guide groove, a protruding block and a retreat groove, and the guide groove corresponds to the guide member on the same vertical line, so that the guide member moves along the guide groove when it moves to the highest point.

[0011] As a further improvement, the self-locking member includes a convex portion and a self-locking portion. When the guide member starts to move along the guide groove, the convex portion abuts against the protruding block to allow the self-locking member to rotate around the hinge point. When the guide member is placed at the highest point, the self-locking portion is located in the retreat groove, and the self-locking member and the hook head are in an open state.

[0012] As a further improvement, the self-locking part includes an anti-falling part and a tightening part, the anti-falling part and the tightening part intersect vertically, the anti-falling part abuts against the side wall of the material frame handle, and the tightening part abuts against the top of the material frame handle to prevent the material frame from falling off during the quenching process.

[0013] As a further improvement, a V-shaped groove is provided on the hook head, and a lifting portion matching the V-shaped groove is provided on the material frame handle to limit the left and right movement of the material frame.

[0014] As a further improvement, the conveying chain device also includes a chain storage box, which is fixed on the base, and the chain transmission mechanism is placed between the base and the chain storage box. When the driving mechanism drives the chain transmission mechanism to rotate and causes the hook to move upward, the chain storage box is used to accommodate the chain.

[0015] As a further improvement, there are four grooves, two at each of the front and rear ends.

[0016] As a further improvement, the front end portion of the front fork mechanism is an abutment portion for abutting against the side wall of the material frame to increase the depth of the material frame entering the heating furnace.

[0017] By adopting the above technical solution, the present invention can achieve the following technical effects:

[0018] 1. The present invention places the materials in the material frame, which can more conveniently concentrate the materials and can simultaneously perform heat treatment on multiple materials, thereby reducing the waste of materials caused by the failure to take out the materials in time during disordered heat treatment.

[0019] 2. The transport device of the present invention can not only use the front fork mechanism to transport the material into the heating furnace, but also transfer the material into the quenching tank. One transport device can complete the heat treatment process of the material, reducing the problem of the overly complicated transmission process.

[0020] 3. The self-locking part provided on the hook in the conveyor chain device of the present invention cleverly uses its own structure to abut the protruding block on the base to open the hook to extract the material frame. During the transmission process, the hook can be locked due to its own gravity to prevent the material frame from being unhooked. In the quenching tank, it can also resist the unhooking of the material frame due to its own buoyancy.

[0021] 4. The front fork mechanism abuts against the side wall of the material frame to increase the depth of the material frame entering the heating furnace, so that the material frame can reach the central part of the heating, preventing the material frame from entering too shallowly and failing to be fully heated.

[0036] Example

[0037] Combination Figures 1 to 7 This embodiment provides a transport device for a material frame, which is used to heat-treat the material placed in the material frame 5, and includes: a base 1, a clamping plate 2 for a manipulator to clamp, a front fork mechanism 3 for transporting the material frame 5 into and out of the heating furnace, and a conveying chain device 4 for transporting the material frame 5 into and out of the quenching tank. The clamping plate 2 is fixed on the base 1, and is connected to the connecting plate on the manipulator, so that the transport device is moved to a predetermined position through the manipulator operation, thereby completing the material transport. Through the intelligent application of the manipulator, the working environment of the operator in the heating system can be improved, and the production efficiency and production quality can be improved.

[0038] Reference Figure 2 and Figure 3In this embodiment, the material frame 5 includes a receiving cavity 51, a hanging ring 52 and a handle 53. The receiving cavity 51 is used to place the material to be processed. The hanging ring 52 is used to cooperate with the front fork mechanism 3 to transport the material frame 5 into and out of the heating furnace. The front fork mechanism 3 is fixed to the front end of the base 1 to facilitate the clamping of the material tray. The front fork mechanism 3 includes at least two clamping racks, preferably two, and the clamping racks are long arm-shaped. Each clamping rack is provided with at least two grooves 31, which are respectively arranged at the front and rear ends. The hanging ring 52 is preferably four, which are arranged around the receiving cavity 51 to facilitate the clamping rack to clamp the material frame 5, which is beneficial to the balance of the material frame 5 during the transportation process and increases the stability of transportation. Similarly, four grooves 31 are preferred, two at each of the front and rear ends, which is beneficial to the coordination of the grooves 31 and the hanging ring 52 at multiple positions, and reduces the time of the corresponding grooves 31 and the hanging ring 52. The handle 53 is used to cooperate with the conveyor chain device 4 to convey the material frame 5 into and out of the quenching tank. The conveyor chain device 4 is fixed to the lower end of the base 1. The conveyor chain device 4 includes a driving mechanism 41, a chain transmission mechanism 42 and a hook 43. The hook 43 is connected to the end of the chain 7 of the chain transmission mechanism 42. The hook 43 is used to lift the handle 53. The driving mechanism 41 drives the chain transmission mechanism 42 to rotate so that the hook 43 descends or rises to convey the material frame 5 into or out of the quenching tank.

[0039] Reference Figure 1 , Figure 4 , Figure 5 and Figure 6 The hook 43 includes a hook head 431, a guide member 432 and a self-locking member 6. The guide member 432 is arranged at the top of the hook 43 and connected to the chain 7. The self-locking member 6 is hinged between the hook head 431 and the guide member 432. The self-locking member 6 is arranged on the left or right side of the hook head 431 and the guide member 432. The self-locking member 6 and the hook head 431 can be in a closed or open state under the action of force. In this embodiment, there are two hooks 43, connected by a vertical rod in the middle, so that the two hooks 43 form a whole. The self-locking member 6 is arranged on the outer sides of the two ends of the hook head 431, which can reduce the exposure of the chain 7 and make the overall device more beautiful. A guide groove 13, a protruding block 11 and a retreat groove 12 are also provided on the base 1. The guide groove 13 and the guide member 432 are on the same vertical line and correspond to each other, so that the guide member 432 moves along the guide groove 13 when it moves to the highest point. When the guide member 432 enters the guide groove 13, the self-locking member 6 abuts against the protruding block 11 so that the self-locking member 6 rotates around the hinge point when the guide member 432 moves upward, so that the self-locking member 6 and the hook head 431 are in an open state, and at this time the self-locking member 6 is in the retreat groove 12 due to its ascent.

[0040] Specifically, the locking member includes a convex portion 61 and a self-locking member 6. When the driving mechanism 41 drives the chain transmission mechanism 42 to transmit, the hook 43 rises. When the hook 43 rises to a certain position, the convex portion 61 just abuts against the protruding block 11. When the guide member 432 on the hook 43 continues to move upward, the contact between the convex portion 61 and the protruding block 11 generates a force that enables the self-locking member 6 to rotate along the hinge point, so that the self-locking member 6 can continue to move upward without being stuck on the protruding block 11. The self-locking member 6 and the hook head 431 are opened at a sufficiently large angle so that the hook head 431 can more easily lift the handle 53 of the material frame 5, and a retreat groove 12 is opened on the base 1 so that the self-locking member 6 will not be stuck on the base 1 when rotating, so that the self-locking member 6 can rotate completely freely during the mutual contact between the protrusion 61 and the protruding block 11, and when the protrusion 61 and the protruding block 11 are in contact, the guide member 432 begins to enter the guide groove 13, which can prevent the hook 43 from shaking and keep the hook 43 in a fixed position.

[0041] Reference Figure 1 and Figure 3 A V-shaped groove 433 is provided on the hook head 431, and a lifting portion 531 matching the V-shaped groove 433 is provided on the handle 53 of the material frame 5. The cooperation of the two can limit the left and right movement of the material frame 5 on the hook 43, and can also prevent the material frame 5 from moving forward and backward, so that the material frame 5 remains relatively fixed during the lifting process, and the material frame 5 will not be unhooked due to the shaking of the chain 7. When the hook 43 lifts the material frame 5 and transmits it downward, after the guide member 432 leaves the guide groove 13, the self-locking member 6 will rotate along the hinge point under the action of its own gravity, and at this time the self-locking portion 62 will be stuck on the handle 53, thereby generating self-locking. Specifically, the self-locking part 62 includes an anti-falling part 621 and a tightening part 622, and the anti-falling part 621 and the tightening part 622 intersect vertically. Under the gravity of the self-locking member 6, the anti-falling part 621 abuts against the side wall of the handle 53 of the material frame 5, and the tightening part 622 abuts against the top of the handle 53 of the material frame 5. When the material frame 5 is rapidly transported downward by the hook 43, if the material frame 5 is to rise or move sideways to escape from the groove 31, the anti-falling part 621 and the tightening part 622 will abut against the material frame 5 to limit it in the groove 31, so that the material frame 5 will not be unhooked. After the material frame 5 enters the quenching tank, the buoyancy of the water will cause the material frame 5 to rise, and the top of the handle 53 will rise to tighten the tightening part 622 of the self-locking member 6. At this time, the tightening part 622 will play a role of blocking to prevent the material frame 5 from being unhooked.

[0042] Reference Figure 7The chain 7 is for lifting and lowering. When the hook 43 rises, the chain 7 will descend to the other end of the chain transmission mechanism 42. Since no object is lifted at this end, the chain 7 is likely to swing, affecting safety. Therefore, a chain storage box 44 is also provided on the conveyor chain device 4. The chain storage box 44 is fixed on the base 1, and the chain transmission mechanism 42 is placed between the base 1 and the chain storage box 44. When the driving mechanism 41 drives the chain transmission mechanism 42 to rotate and make the hook 43 move upward, the rising chain 7 will be stored in the chain storage box 44, and the chain storage box 44 can wrap the driving mechanism 41 and the chain transmission mechanism 42 completely therein, which not only ensures the safety of transportation, but also makes the transportation device more concise and beautiful.

[0043] Reference Figure 1 and Figure 2 The material frame 5 is not easily accessible to the user because of the high temperature of the heating furnace.

[0044] The material frame 5 is then moved to the workbench, where it is then brought into contact with the load box 5. The material frame 5 is brought into contact with the load box 5, where it is then brought into contact with the load box 5. The clamping portion 531 on the hook head 431 cooperates with the V-shaped groove 433 on the hook head 431, and then the manipulator drives the handling device to bring the material frame 5 to the top of the quenching tank, and the driving mechanism 41 drives the chain 7 to descend. At the same time, the self-locking member 6 rotates along the hinge point due to its own gravity to self-lock when the material frame 5 is lowered. When the material frame 5 enters the quenching tank, the buoyancy of the water will cause the material frame 5 to rise. At this time, the tightening portion 622 on the self-locking member 6 plays a blocking role, clamping the material frame 5 to prevent the material frame 5 from being unhooked. After the quenching is completed, the chain 7 rises, the retracted chain 7 is recovered to the chain 7 storage box, the handling device moves the material frame 5 to the workbench, the driving mechanism 41 continues to drive the chain transmission mechanism 42 to transmit, and the guide member 432 continues to move upward along the guide groove 13. At this time, the convex portion 61 on the self-locking member 6 abuts against the protruding block 11 on the base 1, thereby opening the hook 43 and unloading the material frame 5 onto the workbench, completing a heat treatment process, and the above actions are cyclically performed to complete the heat treatment of the material. The handling device can use the front fork mechanism 3 to transport the material into the heating furnace, and can also transfer the material into the quenching tank. One handling device can complete the heat treatment process of the material, reducing the problem of the transmission process being too cumbersome.

[0045] The above are only preferred implementations of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention.
