[0002] In construction machinery, many large parts need to be bent and formed. In the process of sheet metal bending and forming, a large number of upper molds with different specifications are generally required. The upper molds are usually piled or stacked together and stored on a pallet or on the ground.

[0003] However, such long-term stacking is not only prone to deformation of the upper molds due to mutual squeezing between the upper molds, but also prone to falling and damage due to unstable stacking, which is inconvenient to manage and poses a great safety hazard. In addition, the storage and transportation of the upper molds also requires a lot of manual operation, which is time-consuming and labor-intensive, occupies a large area, and is prone to collision and damage to the upper molds, which is dangerous. Summary of the invention

[0004] The purpose of this application is to provide a storage rack, a transfer tool and a transfer and installation method for the upper mold of a bending machine, so as to facilitate the storage, transfer and disassembly of the upper mold and improve work efficiency.

[0015] In some embodiments, the storage rack further comprises:

[0016] The movable stop pin and the fixed stop pin are arranged at both ends of the hanging plate;

[0017] Among them, the end of the hanging plate is provided with a movable slide groove that slides with the movable stop pin, the first slide groove end of the movable slide groove is higher than the sliding assembly structure and the second slide groove end is lower than the sliding assembly structure, so that when the movable stop pin slides to the first slide groove end, the movable stop pin is located above the upper mold, and when the movable stop pin slides to the second slide groove end, the movable stop pin stops at the end face of the upper mold to lock the upper mold.

[0018] In some embodiments, the frame body is a four-frame structure and includes stacked legs arranged at the frame corners, the stacked legs including upper legs passing upward through the frame corners and lower legs passing downward through the frame corners;

[0022] Moving the vehicle; and

[0023] The above-mentioned storage rack is loaded on the mobile vehicle body.

[0024] In some embodiments, a plurality of stacked storage racks are loaded on the mobile vehicle.

[0025] A third aspect of the present application provides a method for transporting and installing an upper mold of a bending machine, the method comprising the steps of:

[0026] Move the transfer tool to the end position of the bending machine, so that the mold handle in the bending machine and the upper mold in the storage rack are both placed along the width direction of the frame body;

[0054] The specific implementation of the present application is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present application, and is not used to limit the present application.

[0055] The following describes the storage rack, transfer tooling and transfer installation method of the upper mold of the bending machine according to the present application with reference to the accompanying drawings.

[0056] The present application discloses a novel storage rack 100, such as Figures 1 to 4 As shown, a storage rack 100 in a specific embodiment includes:

[0057] Frame body 110;

[0058] The hanging plate 121 is arranged in the frame space of the frame body 110 and the two ends are installed on the frame edge of the frame body 110;

[0059] The hanging plate 121 is provided with a sliding assembly structure 120 that is slidably matched with the upper mold assembly groove 310 , and the upper mold 300 is slidably assembled and disassembled on the hanging plate 121 .

[0060] Specifically, see Figure 1 and Figure 3 , the hanging plate 121 accommodated in the frame space is extended along the width direction L2 of the frame body (i.e., the sliding and disassembly direction of the upper mold 300 and the hanging plate 121). Compared with the existing storage method of stacking the upper molds 300, the storage rack 100 of the present application can use the frame space to store one or more upper molds 300, which is beneficial to the management of the upper molds 300 and reduces the collision risk of the upper molds 300. The upper mold 300 is only affected by its own weight during the storage process, avoiding the risk of mutual squeezing between the upper molds 300 caused by the stacking storage method, thereby ensuring the structural performance of the upper mold 300. In addition, the setting of the upper mold 300 sliding and disassembling on the hanging plate 121 greatly reduces the difficulty of disassembly and the manpower required. As an example, see Fig.10 , the end of the hanging plate 121 can be aligned with the end of the die handle 400 of the bending machine, and the upper die 300 can be directly slid from the die handle 400 to the hanging plate 121. Similarly, the upper die 300 can also be conveniently slid from the hanging plate 121 to the die handle 400. Among them, the frame body 110 can be welded by rectangular tubes, which is easy to obtain and convenient to process.

[0061] Those skilled in the art will appreciate that the sliding assembly structure 120 that slides with the upper mold 300 may be in various forms, such as a boss formed on the hanging plate 121 that fits the upper mold assembly slot 310 .

[0062] In this embodiment, if Figure 1 As shown, multiple hanging plates 121 are arranged in sequence along the length direction L1 of the frame body 110, and the hanging plates 121 extend along the width direction L2 of the frame body 110. Multiple upper molds 300 can be slidably assembled and disassembled on the multiple hanging plates 121 along the width direction L2 of the frame body.

[0063] In this way, the storage rack 100 can effectively utilize the limited space to orderly store multiple upper molds 300, which not only further facilitates the management of the upper molds 300, but also avoids the risk of mutual squeezing and collision between the multiple upper molds 300 to ensure the structural performance of the upper mold 300.

[0064] In this embodiment, if Figure 1 , Figure 3 and Figure 6 As shown, the sliding assembly structure 120 may include:

[0065] A plurality of assembly pins 122 are arranged in sequence and spaced apart along the width direction L2 of the frame body. The assembly pins 122 penetrate the hanging plate 121 and have two ends extending out of two sides of the hanging plate 121 .

[0066] Specifically, see Figure 3 and Figure 6, so that the assembly pin 122 can slide into the upper mold assembly slot 310, and the protruding portion of the assembly pin 122 abuts against the inner wall surface of the upper mold assembly slot 310 to vertically limit the upper mold 300. In some embodiments, the assembly pin 122 can be pivotally arranged on the hanging plate 121, so as to reduce the resistance of the upper mold 300 during the sliding and disassembly process by rolling itself.

[0067] Of course, the structure of the assembly pin 122 can be in various forms, not limited to the above-mentioned setting of penetrating the hanging plate 121 and extending both ends from both sides of the hanging plate 121, but can also be suspended below the hanging plate 121 or extending only from one side, and the number of the assembly pins 122 is not limited to the five shown in the figure, but can also be set to other numbers according to the specifications of the storage rack 100. The way in which the sliding assembly structure 120 vertically limits the upper mold 300 is not limited to the above-mentioned assembly pin 122, and can be a slider groove fit, etc.

[0068] In this embodiment, if Figure 5 As shown, the upper mold assembly slot 310 can be a T-slot, the assembly pin 122 and the upper mold assembly slot 310 form a keyway fit, and the upper mold 300 can be hoisted below the hanging plate 121.

[0069] Specifically, the assembly pin 122 can slide into the horizontal hole of the T-slot in sequence, and the assembly pin 122 abuts against the upper end surface of the horizontal hole, thereby fixing the upper mold 300. Among them, the vertical hole of the T-slot connected to the horizontal hole can accommodate the hanging plate 121 and stabilize the sliding direction of the upper mold 300.

[0070] In this embodiment, if Figure 1 and Figure 3 As shown, the storage rack 100 may also include:

[0071] The fixed stop pin 123 is provided at one end of the hanging plate 121 and is used to position and stop the upper mold 300 slidably mounted on the plurality of hanging plates 121 along the width direction L2 of the frame body. The setting of the fixed stop pin 123 facilitates the fixing of the upper mold 300 on the hanging plate 121, thereby improving the reliability and safety of the storage rack 100.

[0072] Of course, the setting of the fixed stop pin 123 is not limited to the above-mentioned hanging plate 121, and can also be set on the frame body 110. The positioning stop of the upper mold 300 can be implemented in many ways, not limited to the above-mentioned fixed stop pin 123, and can also be a baffle set at one end of the frame body 110 or other ways.

[0073] In order to further improve the reliability and safety of the storage rack 100. In this embodiment, Figure 4 As shown, the storage rack 100 may also include:

[0074] The movable stop pin 124 and the fixed stop pin 123 are arranged at both ends of the hanging plate 121;

[0075] Among them, the end of the hanging plate 121 is provided with a movable slide groove 121a that slides with the movable stop pin 124. The first slide groove end of the movable slide groove 121a is higher than the sliding assembly structure 120 and the second slide groove end is lower than the sliding assembly structure 120, so that when the movable stop pin 124 slides to the first slide groove end, the movable stop pin 124 is located above the upper mold 300, and when the movable stop pin 124 slides to the second slide groove end, the movable stop pin 124 stops at the end face of the upper mold 300 to lock the upper mold 300.

[0076] Specifically, see Figure 4 The movable slide groove 121a is an L-shaped slide groove that is arranged horizontally through the hanging plate 121, and the movable stop pin 124 can be slidably clamped in the L-shaped slide groove. When the movable stop pin 124 is located in the upper horizontal extension hole of the L-shaped slide groove, the upper mold 300 can be slidably assembled onto the hanging plate 121, and when the movable stop pin 124 is located in the lower vertical extension hole of the L-shaped slide groove, the movable stop pin 124 and the fixed stop pin 123 can respectively correspond to the two ends of the upper mold 300. Obviously, the upper mold 300 can be unlocked after the movable stop pin 124 slides into the upper horizontal extension hole. In this way, the reliability, safety and ease of use of the storage rack 100 can be further improved, and the risk of damage caused by the upper mold 300 falling is reduced, and the structure is simple, easy to process and easy to operate.

[0077] Of course, the unlocking and fixing of the upper mold 300 relative to the sliding assembly structure 120 can be in various forms, and is not limited to the above-mentioned cooperation between the movable stop pin 124 and the fixed stop pin 123, and can also be in other forms.

[0078] In this embodiment, if Figure 1 and Figure 2 As shown, the frame body 110 may be a four-frame structure and include stacked legs 111 arranged at the frame corners, and the stacked legs 111 may include leg upper ends 111a passing upward through the frame corners and leg lower ends 111b passing downward through the frame corners;

[0079] When two adjacent storage racks 100 are stacked, the lower ends 111 b of the legs of the upper storage rack 100 can be aligned and inserted into the upper ends 111 a of the legs of the lower storage rack 100 .

[0080] Specifically, see Figure 3 and Figure 6Such a configuration can facilitate the stacking and storage of multiple storage racks 100, greatly saving the floor space occupied by the upper mold 300, and also facilitate the operator to stack the storage racks 100. When the specifications and quantity of the upper molds 300 are large, it is also conducive to the classification management of the upper molds 300. The design that the lower end 111b of the leg of the upper storage rack 100 can be inserted into the upper end 111a of the leg of the lower storage rack 100 ensures that the connection between the storage racks 100 is stable, safe, and reliable.

[0081] In this embodiment, if Figure 1 and Figure 3 As shown, two sides of the frame body 110 may be provided with hanging ears 112 respectively.

[0082] Specifically, see Figure 1 The lifting lugs 112 are welded to both sides of the frame body 110 to facilitate operators to transport the storage rack 100 by means of a vehicle or other tools. Of course, the number of the lifting lugs 112 is not limited to the four shown in the figure, and can also be set to other numbers according to the specifications of the storage rack 100.

[0083] The present application also protects a transfer tool. In a specific implementation, the transfer tool includes a mobile body 210 and the above-mentioned storage rack 100 , and the storage rack 100 is loaded on the mobile body 210 .

[0084] The mobile body 210 can greatly facilitate the transportation of the storage rack 100. The mobile body 210 can be a frame structure composed of rectangular tubes welded together. In order to facilitate the storage rack 100 to be loaded on the mobile body 210 and ensure the connection between the two is stable, the upper end of the frame structure can be provided with a mounting structure adapted to the lower end 111b of the leg. In addition, in order to further improve the convenience of the operation of the transport tooling, see Figures 7 to 10 , the two sides of the mobile body 210 along the length direction L1 of the frame body can correspond to a set of directional casters 211 and a set of universal casters 212 respectively. As an example, after the end of the hanging plate 121 is aligned with the end of the mold handle 400 of the bending machine and the upper mold 300 is disassembled and assembled between the mold handle 400 and the hanging plate 121, the mobile body 210 can continue to be stably pushed along the length direction L1 of the frame body, and facilitate the disassembly and assembly of the next upper mold 300. In some embodiments, the directional casters 211 and the universal casters 212 can both be shock-absorbing directional pulleys and shock-absorbing universal pulleys to avoid the upper mold 300 from accidentally falling due to factors such as vibration. The shock-absorbing directional pulleys and shock-absorbing universal pulleys can support the weight of the overall structure, alleviate vibration, assist in moving forward, and assist in steering control.

[0085] Obviously, the transfer tool also has all the technical effects of the above-mentioned storage rack 100, so it will not be described here.

[0086] In this embodiment, a plurality of stacked storage racks 100 may be mounted on the mobile body 210. In this way, not only the transport capacity of the mobile body 210 is improved, but also when transporting upper molds 300 of different specifications, the upper molds 300 can be classified and stored on different storage racks 100, thereby facilitating subsequent disassembly and assembly.

[0087] The present application also protects a method for transporting and installing an upper mold 300 of a bending machine. The method for transporting and installing in a specific embodiment includes the following steps:

[0088] Move the above-mentioned transfer tool to the end position of the bending machine, so that the mold handle 400 in the bending machine and the upper mold 300 in the storage rack 100 are both placed along the width direction L2 of the frame body;

[0089] The bending machine is operated to raise or lower the end position of the die handle 400 so that the end of the die handle 400 is aligned with the upper die 300;

[0090] The upper mold 300 is slidably mounted from the hanging plate 121 to the mold handle 400 .

[0091] Specifically, the storage rack 100 with multiple upper molds 300 installed can be first loaded onto the transfer tooling by a crane or other tools to overlap with the existing storage rack 100 or directly loaded onto the mobile body 210 of the transfer tooling. Then, the transfer tooling is pushed to the end position of the bending machine, and it is ensured that the side of the storage rack 100 with the movable stop pin 124 is close to the bending machine, and the mold handle 400 of the bending machine is parallel to the upper mold 300 in the storage rack 100, see Fig.10 . Adjust the position of the transfer tooling along the length direction L1 of the frame body so that the predetermined upper mold 300 is flush with the mold handle 400. Lift and lower the mold handle 400 to achieve that the mold handle 400 is level with the predetermined upper mold 300. After the mold handle 400 is coaxial with the predetermined upper mold 300, slide the movable stop pin 124 from the second slide groove end to the first slide groove end, and slide the predetermined upper mold 300 from the hanging plate 121 to the mold handle 400. Thereafter, similarly, the installation of the remaining upper mold 300 can be continued by adjusting the position of the transfer tooling and / or adjusting the height of the mold handle 400. It can be seen that the transfer and installation method has high operating efficiency and is easy to operate. It does not require the use of tools such as a crane, and can eliminate the steps of operators carrying and assembling back and forth, greatly reducing the labor intensity of operators.

[0092] In summary, the storage rack 100 according to the present application can effectively utilize the limited space to orderly manage multiple upper molds 300 and ensure the structural performance of the upper mold 300. The sliding disassembly setting of the upper mold 300 greatly reduces the difficulty of disassembly and the required manpower.

[0093] In order to further improve the reliability, safety and usability of the storage rack 100, the assembly pin 122 can vertically limit and fix the upper mold 300, the hanging plate 121 can stabilize the sliding direction of the upper mold 300, the movable stop pin 124 and the fixed stop pin 123 can respectively position the two ends of the upper mold 300, and the upper mold 300 can be unlocked by sliding the movable stop pin 124. The overall structure is simple, easy to process and convenient to operate.

[0094] In order to save the floor space occupied by the upper mold 300 , a plurality of storage racks 100 may be stacked and connected via stacking legs 111 , and the connection is stable, safe and reliable.

[0095] In order to facilitate the transportation of the storage rack 100, the transportation tooling may include a mobile body 210, and the mobile body 210 may be provided with shock-absorbing directional pulleys and shock-absorbing universal pulleys that can support the weight of the entire structure, alleviate vibrations, assist in moving forward, and assist in steering control.

[0096] Due to the sliding disassembly arrangement of the upper mold 300, in the transfer and installation method of the upper mold of the bending machine, the upper mold 300 can be easily slid from the hanging plate 121 to the mold handle 400, which has high operating efficiency and is easy to operate, eliminating the steps of the operator carrying and assembling the upper mold 300 back and forth, greatly reducing the labor intensity of the operator.
