Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic press guide structures, in particular to a servo hydraulic press guide structure. Background Art

[0002] A servo hydraulic press is a hydraulic device that uses a servo motor to drive a hydraulic pump to provide power. It is often used for forging, stamping, and stretching parts in the automotive and home appliance manufacturing fields. The guide structure of a servo hydraulic press often consists of four columns as the main guide components, distributed at the four corners of the hydraulic press work surface. This structure has a high load-bearing capacity and can withstand large workloads, making it suitable for various heavy-duty processing occasions.

[0003] Existing servo hydraulic presses often drive the slider to slide between four guide columns, but the friction between the slider and the guide column guide structure will cause wear on the surface of the structure. The friction will increase after long-term operation, and jamming will occur during operation, making the equipment difficult to operate and reducing work efficiency. In addition, impurities will be generated on the surface of the workbench after the pressed object is placed on it for a long time. Existing hydraulic presses are rarely equipped with special cleaning devices, which makes cleaning more difficult.

[0004] In this regard, the present application proposes a servo hydraulic press guide structure to address the technical problems of surface wear of the structure between the slider and the guide column due to friction during long-term operation, jamming during operation, and lack of workbench cleaning facilities. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a servo hydraulic press guide structure, which continuously fills the recycled lubricating oil in the structural gap during operation to prevent the structure from wearing and facilitating the removal and placement of the workbench cleaning device.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] The top end face of said sliding arm is fixedly provided with a toothed connecting strip which is cooperatively connected with said toothed connecting strip.

[0008] Furthermore, guide plates are fixedly connected to both left and right ends of the upper side of the support frame, and the inner walls of the two guide plates are sleeved on the outer wall of the guide column.

[0009] Furthermore, the sliding block and the outer walls of the guide columns corresponding to the two guide plates are all provided with guide holes.

[0010] Furthermore, the left and right ends and the front and rear sides of the oil pump are fixedly connected with oil pipes, and the top ends of the four oil pipes are fixedly connected to the top ends of the two guide plates.

[0011] Furthermore, a bidirectional inclined groove is provided between the left and right ends of the workbench corresponding to the guide columns, and a guide pipe is fixedly connected to the bottom end of the bidirectional inclined groove in the middle of the left and right sides of the top of the oil tank corresponding to the bottom end of the bidirectional inclined groove.

[0012] Furthermore, the connecting assembly includes an L-rod fixedly connected to the opposite ends of the two slides, the inner walls of the two L-rods are sleeved with rotating rods, and the opposite ends of the two brush plates are fixedly connected to the opposite ends of the two rotating rods.

[0013] Furthermore, the bottom ends of the two rotating rods are fixedly connected to a plugging plate, and the front and rear ends of the two plugging plates are provided with slots.

[0014] Furthermore, springs are fixedly connected to both front and rear ends of the inner walls of the two support shells, and one opposite end of the spring is fixedly connected to the opposite end of the limiting ball.

[0015] The utility model has the following beneficial effects:

[0016] 1. In the utility model, an oil tank and an oil pump device are used to continuously add lubricating oil to the surface of the guide column during the operation of the hydraulic press. When the slider slides along the guide column, the friction is greatly reduced, and it is not easy to get stuck. The excess lubricating oil can naturally flow through the collection structure of the workbench and be returned to the oil tank, which facilitates the reuse of the lubricating oil and reduces waste.

[0017] 2. In the present invention, a cleaning structure is provided on the workbench to facilitate cleaning of the workbench, and a limiting structure is provided to facilitate taking and placing of the brush plate, thereby facilitating operation by staff and improving the practicability of the device.

DETAILED DESCRIPTION

[0029] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0030] Reference Figure 1-Figure 3 , the utility model provides an embodiment: a servo hydraulic press guide structure, including a support frame 1 as a protective function, a workbench 11 is fixedly connected to the lower side of the inner wall of the support frame 1, the four corners of the top of the workbench 11 are fixedly connected to guide columns 3, the tops of the four guide columns 3 are fixedly connected to the four corners of the top of the inner wall of the support frame 1, a power supply device 2 is fixedly connected to the middle of the top of the outer wall of the support frame 1, the driving end of the power supply device 2 is fixedly connected to the driving column 6, the bottom end of the driving column 6 is fixedly connected to the slider 5, the inner walls of the four corners of the slider 5 are slidably connected to the outer walls of the four guide columns 3, wherein reference Figure 6 The bottom of the inner wall of the support frame 1 is fixedly connected to the oil tank 8, the middle of the top of the oil tank 8 is fixedly connected to the oil pump 9, and the left and right ends of the upper side of the support frame 1 are fixedly connected to the guide plate 4, wherein the reference Figure 5 The inner walls of the two guide plates 4 are sleeved on the outer wall of the guide column 3, and the slider 5 and the two guide plates 4 are provided with guide holes 12 on the outer wall of the guide column 3. Figure 4 The left and right ends of the oil pump 9 are fixedly connected to the oil pipe 7 on both sides, and the tops of the four oil pipes 7 are fixedly connected to the tops of the two guide plates 4, wherein the reference Figure 7 A two-way inclined slot 14 is provided between the guide columns 3 at the left and right ends of the workbench 11, and a guide pipe 13 is fixedly connected to the bottom end of the two-way inclined slot 14 corresponding to the middle of the left and right sides of the top of the oil tank 8.

[0031] Specifically, when the power supply device 2 drives the slider 5 to operate, the oil pump 9 is turned on to extract the lubricating oil in the oil tank 8 into the oil pipe 7. The oil pipe 7 flows the lubricating oil through the guide plate 4 through the guide hole 12, and then flows through the guide column 3 through the gap between the guide plate 4 and the guide column 3. There are also guide holes 12 at the four corners of the slider 5. The lubricating oil will eventually flow into the two-way chute 14 of the workbench 11 through the gap between the slider 5 and the guide column 3. Due to the action of gravity, the lubricating oil in the two-way chute 14 will eventually re-enter the oil tank through the guide pipe 13. 8, an oil tank 8 and an oil pump 9 are used to continuously add lubricating oil to the surface of the guide column 3 during the operation of the hydraulic press, thereby reducing the friction when the slider 5 slides along the guide column 3 and preventing jamming. The excess lubricating oil can naturally flow through the collection structure of the workbench 11 and be collected back into the oil tank 8, which facilitates the reuse of the lubricating oil and reduces waste. The power supply device 2 ultimately includes a hydraulic cylinder driven by a servo motor, which further drives the slider 5 to operate. A tiny gap will exist between the slider 5 and the guide structure of the guide column 3.

[0032] Reference Figure 8 and Figure 9 , as the two fixed plates 10 of support, the left and right ends of the two fixed plates 10 are fixedly connected to the front and rear ends of the support frame 1, the outer walls of the two fixed plates 10 are slidably connected with slides 15, the opposite ends of the two slides 15 are fixedly connected to L rods 16, the inner walls of the two L rods 16 are sleeved with rotating rods 17, the opposite ends of the two rotating rods 17 are fixedly connected to brush plates 18, the front and rear sides of the top of the workbench 11 are fixedly connected to the support shell 20, the inner walls of the front and rear ends of the support shell 20 are sleeved with limiting balls 21, the bottom ends of the two rotating rods 17 are fixedly connected to the inserting plates 19, the front and rear ends of the two inserting plates 19 are provided with slots, the front and rear ends of the inner walls of the two support shells 20 are fixedly connected with springs 22, and the opposite end of the spring 22 is fixedly connected to the opposite end of the limiting ball 21.

[0033] Specifically, the workbench 11 is cleaned by moving the slide plate 15 to slide on the fixed plate 10, and rotating the rotating rod 17 to control the movement of the brush plate 18 to clean the workbench 11. After cleaning, the slide plate 15 is slid to the corresponding position, and the rotating rod 17 is rotated to align the insert plate 19 between the two limiting balls 21. When the insert plate 19 is inserted, the limiting balls 21 are acted upon by the force to compress the spring 22 and move in opposite directions, and then the insert plate 19 is re-positioned after hitting the slot of the insert plate 19. By providing a cleaning structure on the workbench 11, it is convenient to clean the workbench 11, and the limiting structure facilitates the removal and placement of the brush plate 18, which is convenient for the staff to operate and improves the practicality of the device. The diameter of the space at both ends of the limiting ball 21 is smaller than the center diameter of the limiting ball 21.

[0034] Working principle: When the power supply device 2 drives the slider 5 to run, the oil pump 9 is turned on to draw the lubricating oil in the oil tank 8 into the oil pipe 7. The oil pipe 7 flows the lubricating oil through the guide plate 4 through the guide hole 12, and flows through the guide column 3 through the gap between the guide plate 4 and the guide column 3. There are also guide holes 12 at the four corners of the slider 5. The lubricating oil will pass through the gap between the slider 5 and the guide column 3 and finally flow into the two-way inclined groove 14 of the workbench 11. Due to the action of gravity, the lubricating oil in the two-way inclined groove 14 will eventually re-enter the oil tank 8 through the guide pipe 13. The oil tank 8 and oil pump 9 device are used to continuously add lubricating oil to the surface of the guide column 3 during the operation of the hydraulic press, thereby reducing the friction when the slider 5 slides along the guide column 3, making it less likely to get stuck, and excess lubricating oil can naturally flow through the workbench 11. The collecting structure recycles the oil into the oil tank 8, which is convenient for the reuse of lubricating oil and reduces waste. When the hydraulic press stops running, the workbench 11 is cleaned, the moving slide 15 slides on the fixed plate 10, and the rotating rod 17 is rotated to control the movement of the brush plate 18 to clean the workbench 11. After cleaning, the slide 15 is slid to the corresponding position, and the rotating rod 17 is rotated to align the insert plate 19 between the two limiting balls 21. When the insert plate 19 is inserted, the limiting ball 21 is subjected to the force to compress the spring 22 and move back and forth, and then the insert plate 19 is re-limited after hitting the slot of the insert plate 19. By arranging a cleaning structure on the workbench 11, it is convenient to clean the workbench 11, and the limiting structure makes it convenient to take and put the brush plate 18, which is convenient for the staff to operate and improves the practicality of the device.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
