Description
Technical Field
[0001] This utility model relates to the field of hydraulic press technology, specifically to a layered press with a layered pressurization structure and a large plate. Background Technology
[0002] A hydraulic press (a type of hydraulic press) is a machine that uses special hydraulic oil as the working medium and a hydraulic pump as the power source. The pump's force forces the hydraulic oil through hydraulic lines into the cylinder / piston. The cylinder / piston contains several sets of mutually cooperating seals, each with different seals at different locations, but all serving the purpose of sealing to prevent hydraulic oil leakage. Finally, a one-way valve allows the hydraulic oil to circulate in the oil tank, causing the cylinder / piston to perform work and complete certain mechanical actions, thus serving as a productive force. In the fields of leather and large plate processing, the hydraulic press is a core forming equipment.
[0003] Traditional hydraulic presses are generally equipped with only one pressurizing mechanism (such as a single-layer press plate driven by a single cylinder), which can only press and form a single workpiece (skin or large plate) in a single operation. During the processing, the pressing and demolding of one workpiece must be completed before the next workpiece can be clamped and processed. It is impossible to achieve "layered synchronous processing". For example, when processing skin, if it is necessary to process multiple sets of skin of different specifications or the same specifications at the same time, it is necessary to operate in batches, resulting in a limited processing volume per unit time and difficulty in improving production efficiency. Therefore, in order to solve the above problems, a skin and large plate hydraulic press with a layered pressurizing structure has been proposed. Utility Model Content
[0004] The purpose of this utility model is to provide a layered pressing machine for leather and large plates with a layered pressing structure. The first oil cylinder of the frame drives the upper pressing mechanism and the second oil cylinder drives the lower pressing mechanism to form a layered pressing structure. This changes the limitation of the traditional single mechanism processing one workpiece at a time. It can process multiple sets of leather and large plates simultaneously to improve production efficiency and solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a layered pressing structure for skin and large plate hydraulic press, including a frame, a hydraulic cylinder is installed on the top of the frame, and the piston rod of the hydraulic cylinder passes through the frame and is fixedly connected to an upper pressing mechanism;

[0007] The upper and lower pressing mechanisms are surrounded by limiting components that are fixedly connected to the frame.
[0008] Preferably, the upper pressing mechanism includes an upper movable plate, the upper surface of which is fixedly connected to the piston rod of the first hydraulic cylinder, and a forming mold is installed between the lower surface of the upper movable plate and the upper surface of the lower pressing mechanism. The forming mold is fixedly connected to the upper movable plate and the lower pressing mechanism respectively by fasteners.
[0009] Preferably, the pressing mechanism includes a lower moving plate, the upper surface of which is fixedly connected to the first forming mold, and the lower surface of which is installed between the bottom of the frame and the bottom of the frame, and the second forming mold is fixedly connected to the lower moving plate and the frame respectively by fasteners.
[0010] Preferably, both ends of the lower surface of the upper movable plate and both ends of the upper surface of the lower movable plate are fixedly connected to a limiting plate that cooperates with the forming mold.
[0011] Both ends of the lower surface of the lower moving plate and both ends of the bottom of the frame are fixedly connected to a limiting plate 2 that works in conjunction with the forming mold 2.
[0012] Preferably, the upper movable plate has grooves at both ends, and the second oil cylinder is movably connected within the grooves.
[0013] Preferably, rubber blocks are placed at both ends of the upper surface of the upper movable plate, and the top of the rubber blocks is movably connected to the top of the frame.
[0014] Preferably, the limiting component includes a first sliding sleeve and a second sliding sleeve. The first sliding sleeve is embedded around the upper moving plate, and the second sliding sleeve is embedded around the lower moving plate. A limiting rod is slidably connected between the first sliding sleeve and the second sliding sleeve, and the two ends of the limiting rod are fixedly connected to the top and bottom of the frame.
[0015] Preferably, a spring is sleeved on the surface of the limiting rod, the upper end of the spring is fixed to the lower surface of the upper moving plate, and the lower end of the spring is fixed to the upper surface of the lower moving plate.
[0016] Compared with the prior art, the beneficial effects of this utility model are:
[0017] This utility model provides a layered press for leather and large plates with a layered pressurization structure. The frame is equipped with an upper pressing mechanism driven by a hydraulic cylinder and a lower pressing mechanism driven by a hydraulic cylinder, forming a layered pressurization structure.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] This utility model provides, for example Figures 1-5 The layered press with a layered pressurization structure is shown. It includes a frame 1, a cylinder 2 is installed on the top of the frame 1, and the piston rod of the cylinder 2 passes through the frame 1 and is fixedly connected to the pressing mechanism 3.
[0027] A hydraulic cylinder 4 is installed at a symmetrical position at the top of the inner cavity of the frame 1. The piston rod of the hydraulic cylinder 4 is fixedly connected to a pressing mechanism 5.
[0028] Limiting components 6, which are fixedly connected to the frame 1, are provided around the upper pressing mechanism 3 and the lower pressing mechanism 5.
[0029] The frame 1 serves as the basic support. The top hydraulic cylinder 2 drives the upper pressing mechanism 3 to move, while the hydraulic cylinder 4, symmetrically arranged at the top of the inner cavity, drives the lower pressing mechanism 5 to move. The two form a layered pressurization structure. The limiting components 6 around the upper pressing mechanism 3 and the lower pressing mechanism 5 restrict their movement deviation, realizing layered synchronous pressurization action. This changes the limitation of the traditional single pressurization mechanism, which can only process one workpiece at a time. Through layered pressurization, multiple layers of skin or large plates can be processed simultaneously, increasing the processing volume per unit time. The limiting components 6 ensure the stability of the pressurization process and reduce processing errors caused by mechanism deviation.
[0030] The upper pressing mechanism 3 includes an upper moving plate 31. The upper surface of the upper moving plate 31 is fixedly connected to the piston rod of the oil cylinder 2. A forming mold 32 is installed between the lower surface of the upper moving plate 31 and the upper surface of the lower pressing mechanism 5. The forming mold 32 is fixedly connected to the upper moving plate 31 and the lower pressing mechanism 5 respectively by fasteners 33.
[0031] The upper moving plate 31 of the upper pressing mechanism 3 is driven by the oil cylinder 2. The forming mold 32 between its lower surface and the upper surface of the lower pressing mechanism 5 is fixed by fasteners 33. The upper moving plate 31 drives the forming mold 32 to cooperate with the lower pressing mechanism 5 to complete the pressure forming of the workpiece. The forming mold 32 is fixed by fasteners 33, which facilitates quick disassembly and replacement and is suitable for processing workpieces of different specifications. The stable connection between the forming mold 32 and the upper moving plate 31 and the lower pressing mechanism 5 ensures the accurate position of the mold during pressure application and improves the forming accuracy of the workpiece.
[0032] The pressing mechanism 5 includes a lower moving plate 51. The upper surface of the lower moving plate 51 is fixedly connected to the first forming mold 32. The lower surface of the lower moving plate 51 is installed between the bottom of the frame 1 and the second forming mold 52. The second forming mold 52 is fixedly connected to the lower moving plate 51 and the frame 1 respectively by fasteners 53.
[0033] The lower moving plate 51 of the pressing mechanism 5 is driven by the second hydraulic cylinder 4. The upper surface is connected to the first forming mold 32, and the lower surface is fixed to the bottom of the frame 1 by the second forming mold 52 through the fastener 53. The lower moving plate 51 simultaneously drives the first forming mold 32 to cooperate with the upper moving plate 31 and drives the second forming mold 52 to cooperate with the frame 1, so as to realize the synchronous pressing of the double mold. Through the design of the double forming mold (the first forming mold 32 and the second forming mold 52), two layers of workpieces can be processed at one time, which further improves the production efficiency. The second fastener 53 facilitates the disassembly and assembly of the second forming mold 52, which can adapt to the processing needs of multi-specification skin or large plate.
[0034] Both ends of the lower surface of the upper moving plate 31 and both ends of the upper surface of the lower moving plate 51 are fixedly connected to a limiting plate 7 that is used in conjunction with the forming mold 32;
[0035] Both ends of the lower surface of the lower moving plate 51 and both ends of the bottom of the frame 1 are fixedly connected to the limiting plate 2 8, which is used in conjunction with the forming mold 2 52;
[0036] Limiting plates 7 are fixed to both ends of the lower surface of the upper moving plate 31 and both ends of the upper surface of the lower moving plate 51, respectively, to restrict the displacement of the forming mold 32 in the lateral direction. Limiting plates 8 are fixed to both ends of the lower surface of the lower moving plate 51 and both ends of the bottom of the frame 1, respectively, to restrict the lateral offset of the forming mold 52. By using limiting plates 7 and 8 to constrain the mold in the lateral direction, the mold is prevented from shifting due to force during the pressurization process, ensuring accurate mold alignment, reducing workpiece forming deviation, and improving the stability of processing quality.
[0037] The upper moving plate 31 has grooves 9 at both ends, and the second hydraulic cylinder 4 is movably connected within the grooves 9. The grooves 9 at both ends of the upper moving plate 31 provide space for the second hydraulic cylinder 4 to move. When the upper moving plate 31 moves up and down, the second hydraulic cylinder 4 moves freely within the grooves 9, avoiding structural interference between the upper pressing mechanism 3 and the second hydraulic cylinder 4, solving the problem of motion interference between the upper pressing mechanism 3 and the second hydraulic cylinder 4, ensuring that the upper pressing mechanism 3 and the lower pressing mechanism 5 move independently without affecting each other, optimizing the equipment structure layout, and improving the smoothness of operation.
[0038] Rubber blocks 10 are placed at both ends of the upper surface of the upper movable plate 31, and the top of the rubber blocks 10 is movably connected to the top of the frame 1.
[0039] When the upper moving plate 31 moves to its limit position, the rubber block 10 on its surface contacts the top of the frame 1. The elasticity of the rubber buffers the impact force of the upper moving plate 31 on the frame 1, reduces the rigid collision between the upper moving plate 31 and the frame 1, reduces mechanical wear, extends the service life of the equipment, and at the same time buffers the noise generated by the impact, improving the working environment.
[0040] The limiting component 6 includes a first sliding sleeve 61 and a second sliding sleeve 62. The first sliding sleeve 61 is embedded around the upper moving plate 31, and the second sliding sleeve 62 is embedded around the lower moving plate 51. A limiting rod 63 is slidably connected between the first sliding sleeve 61 and the second sliding sleeve 62. The two ends of the limiting rod 63 are fixedly connected to the top and bottom of the frame 1.
[0041] The limiting rod 63 of the limiting component 6 is fixed to the top and bottom of the frame 1. The sliding sleeve 61 of the upper moving plate 31 and the sliding sleeve 62 of the lower moving plate 51 slide along the limiting rod 63, which restricts the lateral sway of the upper and lower moving plates 51 during the pressurization process and ensures that they move stably in the vertical direction. Through the sliding cooperation between the sliding sleeve and the limiting rod 63, the movement trajectory of the pressurization mechanism is precisely constrained, ensuring that the pressurization force is applied evenly to the workpiece, improving the consistency of forming, and at the same time enhancing the overall stability of the mechanism and reducing the vibration of the equipment during operation.
[0042] A spring 11 is sleeved on the surface of the limiting rod 63. The upper end of the spring 11 is fixed to the lower surface of the upper moving plate 31, and the lower end of the spring 11 is fixed to the upper surface of the lower moving plate 51.
[0043] The spring 11 on the surface of the limit rod 63 connects the lower surface of the upper moving plate 31 and the upper surface of the lower moving plate 51. When the upper and lower moving plates 51 are relatively close or far apart, the spring 11 extends and retracts to generate elastic force, which buffers the relative motion impact between the two and assists the mechanism in resetting. It also buffers the impact force during the pressurization process, reduces the rigid contact wear of the upper moving plate 31, the lower moving plate 51 and the mold, and the resetting assistance of the spring 11 improves the smoothness of the mechanism's movement, shortens non-processing time, and indirectly improves production efficiency.
[0044] In practical use, first place the molding mold 2 52 at the bottom of the frame 1 and align it with the limiting plates 2 8 at both ends of the bottom of the frame 1. The positioning function of the limiting plates 2 8 ensures that the molding mold 2 52 is in a precise position. Then, use fasteners 2 53 to fix the upper end of the molding mold 2 52 to the lower surface of the lower moving plate 51 and fix the lower end to the bottom of the frame 1 to complete the assembly of the lower mold.
[0045] Then, the forming mold 32 is placed on the upper surface of the lower moving plate 51, and the limiting plates 7 at both ends of the upper surface of the lower moving plate 51 are aligned. At the same time, the upper end of the forming mold 32 is made to fit with the limiting plate 7 on the lower surface of the upper moving plate 31. The limiting plate 7 provides double positioning to prevent the mold from shifting. Then, fasteners 33 are used to fix the upper end of the forming mold 32 to the lower surface of the upper moving plate 31 and the lower end to the upper surface of the lower moving plate 51. During this process, it is important to ensure that the grooves 9 at both ends of the upper moving plate 31 correspond to the piston rod position of the hydraulic cylinder 4, so that the hydraulic cylinder 4 can move freely within the grooves 9 and avoid motion interference.
[0046] Next, according to the processing requirements, the large plate workpiece to be processed is placed into the lower forming mold 2 52 to ensure that the workpiece fits the mold cavity without any offset; then the layered skin workpiece to be processed is placed into the upper forming mold 1 32, again ensuring that the workpiece and the mold cavity are precisely matched, thus completing the clamping of the layered workpiece.
[0047] Through an external control system, the piston rod of hydraulic cylinder 2 extends downward, causing the upper moving plate 31 to move downward synchronously. The upper moving plate 31 applies pressure to the inner layer workpiece through the forming mold 32. At the same time, the piston rod of hydraulic cylinder 4 extends downward (because the groove 9 of the upper moving plate 31 provides space for movement, hydraulic cylinder 4 has no movement obstruction), causing the lower moving plate 51 to move downward synchronously. The lower moving plate 51 applies pressure to the inner large plate workpiece through the forming mold 52, realizing independent pressure application of the layer and the large plate. During the pressure application process, sliding sleeve 61 and sliding sleeve 62 always slide along the limit rod 63 to ensure the stability of the movement trajectory of the upper pressing mechanism 3 and the lower pressing mechanism 5, and to avoid mold deviation. The spring 11 plays a buffering role between the upper moving plate 31 and the lower moving plate 51, absorbing the pressure impact and preventing the workpiece from cracking or deforming due to rigid stress. The rubber block 10 prevents the upper moving plate 31 from directly colliding with the top of the frame 1 when it moves to the limit position.
