Description

Technical Field

[0001] The invention belongs to the field of machinery and relates to a stacking device for a pad retaining ring of a wheel forming hydraulic press, which is suitable for lifting and stacking objects with inner holes. Background Art

[0002] During the wheel rolling process, the wheel forming hydraulic press pad retaining ring can fix the die base to prevent the die base from shifting during the rolling process, resulting in the failure of wheel forming. Figure 1 and Figure 2 As shown, the mold base 21 is arranged on the backing plate 22 , and a retaining ring 9 is arranged between the mold base 21 and the backing plate 22 , and the retaining ring 9 effectively prevents the mold base 21 from deflecting.

[0003] In order to facilitate the replacement of retaining ring spare parts during maintenance of the hydraulic press, the retaining ring spare parts generally need to be placed on site. The size and weight of the retaining ring (about 400KG) are relatively large, and need to be transported by a forklift. If each retaining ring is placed on the ground, it will take up a large area of ​​space. If it is piled up, it is easy to slip when transported by a forklift, which poses a safety hazard. Therefore, when the retaining rings need to be transported, they can only be transported individually and cannot be transported in a centralized manner, resulting in a waste of manpower and material resources.

[0004] After searching, Chinese patent CN202640334U discloses a retainer placement rack, including a vertical pole, a support ring and a support beam. Three support beams are evenly distributed and fixed in the radial direction of the support ring. A vertical pole is fixed at each intersection between the support beams in the support ring. The upper end of the vertical pole is made to be horizontally bent toward the center and converged and fixed at the central axis position. The lower end of the vertical pole at the bottom of the support ring is bent outward to form a support foot. The retainer placement rack has a simple structure, stable support, and a light structure, convenient movement, and convenient use. A large number of rubber retainers can be mounted on the placement rack in sequence, which is convenient to use. However, if the retainer placement rack is used to store retainers, there are the following problems: 1. The retainer is very heavy and needs to be transported by a forklift. The retainer placement rack has a light structure and is difficult to support the stacked hydraulic press retainers; 2. The placement rack is provided with a support ring, and the support ring is higher than the support foot. When the retainer is stacked or extracted by a forklift, it is easy to tip over; 3. The placement rack is not provided with a guide device, which is not convenient for placing retainers.

[0005] Therefore, for the above-mentioned problem of lifting and stacking the retaining rings, it is necessary to design a stacking device for the pad retaining rings of the wheel forming hydraulic press to solve the problem. Summary of the invention

[0006] In view of the problem in the background technology that the current retaining rings can only be transported individually and there are safety hazards when stacked, the present invention provides a stacking device for the retaining rings of the wheel forming hydraulic press pads. The application of the present invention can not only solve the problem that the retaining rings cannot be lifted in a centralized manner and there are safety hazards when they are stacked in a centralized manner, but also reduce the labor intensity of workers, improve labor efficiency, and reduce replacement costs. In addition, the stacking device described in the present invention basically does not require a large investment, occupies a small space, and is easy to use and maintain.

[0007] The technical solution of the present invention to solve the technical problem is as follows:

[0008] The present invention provides a stacking device for wheel forming hydraulic press pad retaining rings, which includes a material collecting device for stacking retaining rings and facilitating the lifting of retaining rings; the material collecting device includes three vertically arranged support rods arranged in a triangular shape, preferably in an equilateral triangle shape, and the bottoms of the three support rods are respectively provided with balance plates for supporting the stacked retaining rings, and also facilitating the forklift to stack and fork the retaining rings; the upper, middle and lower parts of the three support rods are respectively fixed with fixing rods between each other to ensure the stability of the entire device. The stacking device is manufactured according to the specifications of the retaining rings to be stacked, ensuring that the support rods arranged in an equilateral triangle shape can be located in the circular holes of the retaining rings. When stacking, the retaining rings are slowly placed from the top of the stacking device to the three balance plates by a forklift, and after the stacking of the retaining rings is completed, the stacking device can be lifted as a whole by a lifting device. The three balancing plates in the stacking device of the present invention are also arranged in an equilateral triangle, which increases the stability of the entire stacking device and solves the safety hazard of the retaining ring spare parts being easily slipped when being stacked on site. After the retaining rings are stacked by the stacking device, they can be transported as a whole, which solves the problem that the retaining rings can only be moved individually, thus causing waste of manpower and material resources. Furthermore, the balancing plate can be set in a trapezoidal shape, with the long bottom side facing outward, which further increases the stability of the stacking device and reduces the safety hazard of the stacking device tipping over.

[0009] As a further improvement of the technical solution of the present invention, the tops of the three support rods can also be respectively provided with first guide rods facing inward, and the three first guide rods generally form an angle of 45 degrees with the horizontal plane. The tops or extension lines of the three can intersect at one point. As long as the inner hole of the retaining ring is ensured to be on the outside of the three first guide rods, the retaining ring can be stacked from top to bottom very conveniently under the action of the three first guide rods.

[0010] In the present invention, because when the forklift is used to stack or fork the retaining rings on the material collection device, the body of the vehicle generally adjusts its position continuously, which may cause the center of the retaining ring and the center of the material collection device to be offset, and thus easily lead to a safety hazard of the material collection device tipping over. Therefore, the present invention further improves the above technical scheme. On the basis of the above technical scheme, a bottom plate is fixedly arranged between the three balance plates; a lifting device is vertically installed on the bottom plate, and a lifting plate is arranged on the top of the lifting device, and the lifting plate can move up and down under the action of the lifting device; a plurality of pull rods are evenly arranged at the edge of the lifting plate, and each pull rod is located between two adjacent support rods, and a support plate is fixedly arranged at the bottom, and the support plate is used to carry the retaining ring.

[0011] During application, when it is necessary to stack the retaining rings on the collecting device, the inner hole position of the retaining rings is lifted and moved to the top of the collecting device by a forklift, and the lifting device is controlled to lift upward, thereby driving the lifting plate and the pull rod to pass through the inner hole of the retaining ring. When the pallet approaches the retaining ring, the retaining rings are placed on each pallet by a forklift or the pallet is directly driven to lift the retaining rings by the lifting device, and the forklift is removed. Then the lifting device is controlled to descend and drive the retaining rings on the pallet to descend synchronously, so that the retaining rings move coaxially with the collecting device, thereby avoiding the safety hazard of the collecting device tipping over due to the deviation of the center of the retaining rings and the center of the collecting device caused by the operation of the forklift during the process of stacking the retaining rings on the collecting device by the forklift.

[0012] When it is necessary to take out the retaining ring from the material collecting device, the lifting device is controlled to move upward, and then the lifting plate, the pull rod and the support plate all move upward, and the retaining ring on the support plate moves upward synchronously, so that the retaining ring and the material collecting device move upward coaxially. When the retaining ring reaches one step height, the retaining ring is taken by a forklift, and then the lifting device is controlled to descend, and the retaining ring falls directly onto the two forks of the forklift. After the bottom of the retaining ring is higher than the top of the lifting plate, the retaining ring is removed by the forklift, thereby avoiding the safety hazard of the retaining ring center and the center of the material collecting device being offset during the process of extracting the retaining ring by the forklift, causing the material collecting device to tip over.

[0013] As a further improvement of the technical solution of the present invention, the lifting device is an oil cylinder, the bottom of which is fixedly connected to the base plate, and the top of the upper piston rod is fixedly connected to the bottom center of the lifting plate. The hydraulic oil used by the oil cylinder can be directly obtained through the hydraulic system of the applied hydraulic press.

[0014] As a further improvement of the technical solution of the present invention, the lifting plate is circular in shape.

[0015] As a further improvement of the technical solution of the present invention, there are three pull rods.

[0016] As a further improvement of the technical solution of the present invention, the pull rod and the lifting plate are detachably connected via a nut.

[0017] As a further improvement of the technical solution of the present invention, the length of the pull rod at least ensures that when the lifting device is lowered to the lowest position, the bottom of the support plate at the bottom of the pull rod is flush with the bottom of the balance plate.

[0018] As a further improvement of the technical solution of the present invention, the support plate is in a trapezoidal shape. When the support plate is lowered to be flush with the bottom of the balance plate, the retaining ring is stacked together by the support plate and the balance plate.

[0019] In order to facilitate the stacking of the retaining rings, the technical solution of the present invention is further improved. A plurality of second guide rods are evenly arranged inwardly on the upper surface of the lifting plate. When the retaining rings are stacked, the second guide rods are convenient for extending into the inner holes of the retaining rings. At the same time, the risk of the retaining rings slipping off the forklift due to direct contact between the lifting plate and the retaining ring when the edge of the lifting plate exceeds the edge of the inner hole of the retaining ring is avoided. The positional relationship between the inner hole of the retaining ring and the lifting plate is observed. If the deviation between the center of the inner hole and the center of the lifting plate is too large, the position of the inner hole of the retaining ring is adjusted in time by the forklift to try to make the center of the inner hole of the retaining ring consistent with the center of the lifting plate.

[0020] Compared with the prior art, the present invention has the following advantages:

[0021] 1. The stacking device for the pad and retaining ring of the wheel forming hydraulic press described in the present invention has a novel and reasonable design, a simple and practical structure, low investment, a small site area, convenient maintenance, safe operation, and reliable use;

[0022] 2. The present invention facilitates the stacking of retaining rings by providing a first guide rod;

[0023] 3. The present invention can more safely and reliably stack and extract the retaining rings by means of a forklift by arranging a lifting device, a lifting plate, a pull rod and a supporting plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Unless otherwise defined, the technical terms or scientific terms used herein shall have the usual meanings understood by persons with ordinary skills in the field to which the present disclosure belongs. The words "upper", "lower", "left", "right", "front", "back", etc. used in the patent application specification and claims of the present disclosure are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship also changes accordingly; "connected" or "connected" and similar words are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect.

[0033] Embodiment 1:

[0034] As shown in the figure, a stacking device for the pad retaining rings of a wheel forming hydraulic press according to the present invention is characterized in that it includes a material collecting device 1 for stacking the retaining rings 9 and facilitating the overall lifting of the retaining rings 9; the material collecting device 1 includes three vertically arranged support rods 11 arranged in an equilateral triangle shape, and the bottoms of the three support rods 11 are respectively provided with balance plates 13 for supporting the stacked retaining rings 9 and also for facilitating the forklift to stack the retaining rings 9 and fork pick up the retaining rings 9; fixing rods 12 are respectively fixedly provided at the upper, middle and lower parts between the three support rods 11 to increase the stability of the entire stacking device. The stacking device is manufactured according to the specifications of the retaining rings to be stacked, ensuring that the support rods 11 arranged in an equilateral triangle shape can be located in the inner hole of the retaining ring 9. When stacking, the retaining rings are slowly placed from the top of the stacking device to the three balance plates 13 in sequence by the two forks of the forklift. After the retaining rings 9 are stacked, the stacking device can be lifted as a whole by the lifting device to change the previous situation of moving the retaining rings 9 individually. The three balance plates 12 in the stacking device described in the present invention are also arranged in an equilateral triangle, which increases the stability of the entire stacking device and solves the safety hazard that the retaining rings 9 spare parts are easily slipped when they are stacked on site. After the retaining rings 9 are stacked by the stacking device, they can be transported as a whole, solving the problem that the retaining rings 9 can only be moved individually, thereby causing waste of manpower and material resources. Furthermore, the balance plate can be set in a trapezoidal shape, with the long bottom side facing outward, further increasing the stability of the stacking device and reducing the safety hazard of the stacking device tipping over.

[0035] In order to make it easier for the forklift to stack the retaining rings, in the present embodiment, the tops of the three support rods 11 may be respectively provided with first guide rods 14 facing inwards. The three first guide rods 11 may generally form an angle of 45 degrees with the horizontal plane, and the tops or extension lines of the three may intersect at one point. As long as the inner hole of the retaining ring is ensured to be on the outside of the three first guide rods, the retaining rings can be very conveniently stacked from top to bottom under the guiding action of the three first guide rods.

[0036] Embodiment 2:

[0037] When Example 1 is in use, because when the retaining rings are stacked on the collecting device or the retaining rings are forked by a forklift, the body of the vehicle will generally be adjusted in position, which may cause the center of the retaining ring and the center of the collecting device to be offset, which may easily lead to a safety hazard of the collecting device tipping over. Therefore, on the basis of Example 1, a bottom plate 3 is fixedly arranged between the three balance plates 13; a lifting device 2 is vertically arranged on the bottom plate 3, and a lifting plate 4 is arranged on the top of the lifting device 2, and the lifting plate 4 can move up and down under the action of the lifting device 2; a plurality of pull rods 7 are evenly penetrated at the edge of the lifting plate 4, and each pull rod 7 is located between two adjacent support rods 11, and a support plate 5 is fixedly arranged at the bottom, and the support plate is used to carry the retaining ring 9.

[0038] In this embodiment, the lifting device 2 can use an oil cylinder, whose bottom is fixedly connected to the base plate 3, and the top of the upper piston rod is fixedly connected to the bottom center of the lifting plate 4. The hydraulic oil used by the oil cylinder can be directly obtained through the hydraulic system of the applied hydraulic press.

[0039] Furthermore, the lifting plate 4 is circular in shape, there are three pull rods 7, the pull rods 7 are detachably connected to the lifting plate 4 via nuts 7, and the length of the pull rods 7 at least ensures that when the lifting device 2 is lowered to the lowest position, the bottom of the support plate 5 at the bottom of the pull rods 7 is flush with the bottom of the balance plate 13.

[0040] Similarly, to facilitate the stacking of the retaining rings 9, the upper surface of the lifting plate 4 described in this embodiment is evenly provided with three second guide rods 6 facing inward, and the arrangement of the second guide rods 6 is similar to the arrangement of the first guide rods 14 in Example 1. In this example, since the first guide rod 14 is no longer functional, it can be omitted. When stacking the retaining rings, it is convenient for the second guide rod to extend into the inner hole of the retaining ring, and at the same time, it is also avoided that when the edge of the lifting plate exceeds the edge of the inner hole of the retaining ring, the risk of the retaining ring slipping off the forklift due to direct contact between the lifting plate and the retaining ring may be avoided. Observe the positional relationship between the inner hole of the retaining ring and the lifting plate. If the deviation between the center of the inner hole and the center of the lifting plate is too large, adjust the position of the inner hole of the retaining ring by the forklift in time, and try to make the center of the inner hole of the retaining ring consistent with the center of the lifting plate.

[0041] In addition, in order to facilitate the stability of the stacking device described in this embodiment when stacking the retaining rings, the support plate 5 can also be set in a trapezoidal shape, with the long bottom side facing outwards and the short bottom side facing inwards.

[0042] During application, when it is necessary to stack the retaining ring on the collecting device, the inner hole position of the retaining ring is lifted and moved to the top of the collecting device by a forklift, and the lifting device (i.e., the oil cylinder) is controlled to lift upward, thereby driving the lifting plate and the pull rod to pass through the inner hole of the retaining ring. When the pallet approaches the retaining ring, the retaining ring is placed on each pallet by a forklift or the pallet is directly driven to lift the retaining ring by the lifting device, and then the forklift is removed, the lifting device is controlled to descend and drive the retaining ring on the pallet to descend synchronously, so that the retaining ring moves coaxially with the collecting device, thereby avoiding the safety hazard of the collecting device tipping over due to the deviation of the center of the retaining ring and the center of the collecting device during the process of stacking the retaining ring on the collecting device by the forklift.

[0043] When it is necessary to take out the retaining ring from the material collecting device, the lifting device is controlled to move upward, and then the lifting plate, the pull rod and the support plate all move upward, and the retaining ring on the support plate moves upward synchronously, so that the retaining ring and the material collecting device move upward coaxially. When the retaining ring reaches one step height, the retaining ring is taken by a forklift, and then the lifting device is controlled to descend, and the retaining ring falls directly onto the fork. After the bottom of the retaining ring is higher than the top of the lifting plate, the retaining ring is removed by a forklift, thereby avoiding the safety hazard that the center of the retaining ring and the center of the material collecting device are offset during the process of extracting the retaining ring by the forklift, which may cause the material collecting device to tip over.

[0044] The above are only preferred embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be defined by the claims.
