Description

Technical Field

[0001] This utility model relates to the field of tilting machines, and in particular to an ultra-large heavy-duty hydraulic tilting machine with equal height. Background Technology

[0002] In routine mold maintenance, molds often need to be flipped. Small mold flipping machines on the market mainly include mechanical rotary mold flipping machines. However, these machines often encounter difficulties in processing a semi-circular mold when the worktable is too large (i.e., the worktable has difficulty flipping into a semi-circle), making this impossible. Another type, hydraulic mold flipping machines, often have two worktables at different heights when flipped to a horizontal position due to considerations of the center of gravity. This difference in height makes mold handling inconvenient, and the different sizes of the worktables require different forces for flipping, easily causing instability. These problems ultimately result in a large difference in platform height when the two worktables are placed horizontally, making them inconvenient to use. Furthermore, current mold flipping machines frequently experience vibration or shaking after stopping. Summary of the Invention

[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide an ultra-large heavy-duty hydraulic tilting machine with equal height.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The ultra-large heavy-duty hydraulic tilting machine includes a base, a tilting frame, a first oil cylinder, a second oil cylinder, a first worktable, a second worktable, a first support, a second support, a first rotating shaft, and a second rotating shaft. The first oil cylinder is rotatably mounted on the base via the first support, and the output shaft of the first oil cylinder is rotatably connected to one end of the tilting frame via the first rotating shaft. The second oil cylinder is rotatably mounted on the base via the second support, and the output shaft of the second oil cylinder is rotatably connected to the other end of the tilting frame via the second rotating shaft. The first worktable and the second worktable are respectively mounted on the two ends of the tilting frame, and the tilting frame is rotatably connected to the base via a third rotating shaft and a bearing seat. The second worktable is respectively equipped with a first bottom pad channel steel and a second bottom pad channel steel for adaptively lining the bottom of molds with uneven bottom heights. One end of the base is provided with a first support column to support one end of the tilting frame, and the other end of the base is provided with a second support column to support the other end of the tilting frame.

[0005] By adopting the above technical solution, not only can the mold be smoothly rotated with the first and second worktables, but it also prevents a large difference in platform height when the first and second worktables are placed horizontally. It also avoids the phenomenon of weightlessness of the mold during the rotation of the first and second worktables. This effectively solves the problem that the rotating worktable of small rotating machines on the market (such as mechanical rotary mold turning machines) cannot achieve semi-circular processing (i.e., semi-circular rotation) for molds that are too large. It also effectively solves the problem that hydraulic mold turning machines are prone to large platform height differences when the two worktables are placed horizontally due to weightlessness during the mold turning process.

[0006] Preferably, the first worktable and the second worktable are arranged perpendicular to each other.

[0007] Preferably, the longitudinal section of the tilting frame is L-shaped.

[0008] Preferably, the heights of the first bottom pad channel steel and the second bottom pad channel steel are different, and there is one or more of the first bottom pad channel steel and the second bottom pad channel steel.

[0009] Preferably, a third hydraulic cylinder is vertically provided on one side of the second support column to tighten and buffer the tilting frame.

[0010] Specifically, one side of the base is provided with oil tanks that supply oil to the first, second, and third oil cylinders respectively.

[0011] Specifically, an electrical control box is provided on one side of the fuel tank.

[0012] Preferably, the electrical control box has a built-in controller or control system that controls the signals of the first, second, and third hydraulic cylinders respectively. The controller is a PLC programmable logic controller, which can be a programmable logic controller of model XDS-40T-D, but is not limited thereto.

[0013] Compared with existing technologies, the beneficial effects of this utility model are as follows:

[0014] 1. When the mold needs to be flipped from the first worktable to the second worktable, the first hydraulic cylinder first generates a pushing force on one end of the flipping frame and the second hydraulic cylinder generates a pulling force on the other end of the flipping frame. When the center of gravity of the mold changes during the flipping process, the first hydraulic cylinder changes the force on one end of the flipping frame from pushing to pulling and the second hydraulic cylinder changes the force on the other end of the flipping frame from pulling to pushing. It adopts a two-way hydraulic balance structure technology to keep the first and second hydraulic cylinders in a rigid state at all times, so that there will be no weight loss. This solves the problem of unstable flipping of the two worktables due to the different forces required for flipping the two worktables of different sizes in the current mold flipping equipment (mold flipping machine) on the market, and also solves the problem of large platform height difference between the two worktables due to weight loss in the current hydraulic mold flipping machine on the market.

[0015] 2. It eliminates hydraulic pulsation caused by instantaneous machine tool stop by using a micro-orifice throttle valve to relieve pressure, so that the machine tool will not vibrate or shake no matter when it stops, thus solving the problem that the existing mold flipping machines on the market often vibrate or shake after stopping.

[0016] 3. It adapts to uneven molds by installing first and second bottom pads of different heights on the second workbench. The number and position of the first and second bottom pads can be adjusted according to the shape of the mold bottom. First and second support columns are provided at both ends of the base to support the two ends of the flipping frame, so that the first and second workbenches are at the same horizontal height after being flipped to a horizontal state, which facilitates the handling of the mold. It solves the problem that the two workbenches of the existing mold flipping equipment (mold flipping machine) are at different heights when flipped to a horizontal state, which makes it inconvenient to handle the mold.

[0020] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of this utility model. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0022] Reference Figures 1 to 2 As shown, the present invention relates to an ultra-large heavy-duty hydraulic tilting machine with equal height, comprising a base 1, a tilting frame 2, a first hydraulic cylinder 31, a second hydraulic cylinder 32, a first workbench 41, and a second workbench 42. The first hydraulic cylinder 31 is rotatably mounted on the base 1 via a first support 51, and the output shaft of the first hydraulic cylinder 31 is rotatably connected to one end of the tilting frame 2 via a first rotating shaft 61. The second hydraulic cylinder 32 is rotatably mounted on the base 1 via a second support 52, and the output shaft of the second hydraulic cylinder 32 is rotatably connected to the other end of the tilting frame 2 via a second rotating shaft 62. The first workbench 41 and the second workbench 42 are respectively mounted on the two ends of the tilting frame 2, and the tilting frame 2 is rotatably connected to the base 1 via a third rotating shaft 63 and a bearing seat 7. The second workbench 42 is respectively equipped with a first bottom pad channel steel 81 and a second bottom pad channel steel 82 for adaptively lining molds with uneven bottom surfaces. One end of the base 1 is provided with a first support column 91 to support one end of the tilting frame 2, and the other end of the base 1 is provided with a second support column 92 to support the other end of the tilting frame 2. The first workbench 41 and the second workbench 42 are arranged perpendicularly to each other. The longitudinal section of the tilting frame 2 is L-shaped. A third hydraulic cylinder 33 is vertically provided on one side of the second support column 92 to tighten and buffer the tilting frame 2.

[0023] In this embodiment, when the first worktable 41 flips upward from a horizontal position, the second worktable 42 flips downward from a vertical position. The first hydraulic cylinder 31 pushes one end of the flipping frame 2 to flip upward around the third rotating shaft 63, and the first worktable 41 flips upward with the flipping frame 2. When the second worktable 42 flips less than 45 degrees, the second hydraulic cylinder 32 pulls the other end of the flipping frame 2 to flip downward. When the first worktable 41 flips upward more than 45 degrees and the mold flips onto the second worktable 42, the first hydraulic cylinder 31 tightens one end of the flipping frame 2 to buffer the downward flipping of the second worktable 42, and the second hydraulic cylinder 32 presses against the other end of the flipping frame 2 to buffer the downward flipping of the second worktable 42, so that the first worktable 41 and the second worktable 42 can flip smoothly. When the second worktable 42 flips downward to a near-horizontal position, the third hydraulic cylinder 33 presses against the other end of the flipping frame 2 to buffer, the first hydraulic cylinder 31 tightens one end of the flipping frame 2, and the second hydraulic cylinder 32 presses against the other end of the flipping frame 2, so that the second worktable 42 can flip stably to a horizontal position.

[0024] When the first workbench 41 and the second workbench 42 are flipped in opposite directions, the third hydraulic cylinder 33 first assists in pushing the other end of the flipping frame 2. The first hydraulic cylinder 31 pulls one end of the flipping frame 2, and the second hydraulic cylinder 32 pushes the other end of the flipping frame 2. After starting, the third hydraulic cylinder 33 no longer participates in the work, and the first hydraulic cylinder 31 and the second hydraulic cylinder 32 participate in the work. Before the flipping frame 2 flips at an angle of less than 45 degrees, it is pulled by the first hydraulic cylinder 31 and pushed by the second hydraulic cylinder 32. When the flipping frame 2 flips more than 45 degrees and the mold flips from the second workbench 42 to the first workbench 41, the first hydraulic cylinder 31 presses against one end of the flipping frame 2, and the second hydraulic cylinder 32 pulls the other end of the flipping frame 2, so that the first workbench 41 and the second workbench 42 can be flipped in opposite directions smoothly (i.e., reset).

[0025] The first support column 91 supports one end of the flipping frame 2, keeping the first worktable 41 horizontal. The second support column 92 supports the other end of the flipping frame 2, keeping the second worktable 42 horizontal. After the first worktable 41 and the second worktable 42 are flipped to the horizontal position, they are at the same horizontal height. This solves the problem that the two worktables of the mold flipping equipment (mold flipping machine) on the market are at different heights when they are flipped to the horizontal position. It avoids the phenomenon of large height difference when the first worktable 41 and the second worktable 42 are placed horizontally, and makes it easier to move the mold.

[0026] Reference Figure 1 As shown, the height of the first bottom pad channel steel 81 and the height of the second bottom pad channel steel 82 are different, and there is one or more of the first bottom pad channel steel 81 and the second bottom pad channel steel 82.

[0027] In this embodiment, first bottom pad steel 81 and second bottom pad steel 82 of different heights are respectively installed on the second workbench 42. The first bottom pad steel 81 and second bottom pad steel 82 of different heights can adaptively support the mold with uneven bottom surface. The number and installation position of the first bottom pad steel 81 and second bottom pad steel 82 can be adaptively adjusted according to the shape of the bottom surface of the mold. This design ensures that there is no large height difference when the first workbench 41 and the second workbench 42 are placed horizontally, making it more convenient to use. It effectively solves the problem of large height difference of the workbench surface when the two flipping workbench of the existing mold flipping machine are placed horizontally.

[0028] Reference Figure 1 As shown, one side of the base 1 is provided with an oil tank 10 that supplies oil to the first oil cylinder 31, the second oil cylinder 32, and the third oil cylinder 33 respectively. An electrical control box 11 is provided on one side of the oil tank.

[0029] In this embodiment, the electrical control box 11 controls the start and stop of the tilting machine. The oil tank 10 is connected to the first oil cylinder 31, the second oil cylinder 32 and the third oil cylinder 33 through oil pipes. The oil pipes are equipped with micro-orifice throttle valves (micro-orifice throttle valves are a functional description of throttle valves). The oil tank 10 supplies oil to the first oil cylinder 31, the second oil cylinder 32 and the third oil cylinder 33 respectively.

[0030] Reference Figure 1 and Figure 2 As shown, there are more than one first hydraulic cylinder 31 and one second hydraulic cylinder 32. In this embodiment, there are at least two first hydraulic cylinders 31 and two second hydraulic cylinders 32. In other embodiments, the number of first hydraulic cylinders 31 and second hydraulic cylinders 32 can be set differently according to actual conditions, so it is not limited thereto.

[0031] Reference Figure 1 and Figure 2As shown, the flipping control principle of this ultra-large heavy-duty hydraulic flipping machine is as follows: When the mold flips from the first worktable 41 to the second worktable 42, in order to solve the problem of weightlessness when the mold flipping machine flips the mold, the first cylinder 31 first generates a pushing force on one end of the flipping frame 2, and the second cylinder 32 generates a pulling force on the other end of the flipping frame 2 to ensure that the first worktable 41 and the second worktable 42 can flip smoothly. When the center of gravity of the mold changes during the flipping process, the first cylinder 31 changes from pushing to pulling on one end of the flipping frame 2, and the second cylinder 32 changes from pulling to pushing on the other end of the flipping frame 2, so that the mold can flip smoothly, thus solving the problem of the difficulty in processing the semi-circle of the flipping worktable when the mold is too large. Furthermore, it employs bidirectional hydraulic balancing technology to maintain the first cylinder 31 and the second cylinder 32 in a rigid state, preventing weightlessness. It also uses a micro-orifice throttle valve to release pressure and eliminate hydraulic pulsation when the machine tool stops momentarily, ensuring that the machine tool will not vibrate or shake whenever it stops. This ensures that there will be no large height difference between the first worktable 41 and the second worktable 42 when they are placed horizontally, making it more convenient to use.

All technical solutions that are the same as or equivalent to the contents described in the claims of this utility model should be included within the protection scope of this utility model.
