Abstract
Description
Technical Field
[0001] This utility model belongs to the field of hydraulic press technology, specifically relating to a column guide mechanism for a hydraulic press. Background Technology
[0002] The column guide mechanism of a hydraulic press is a core auxiliary component ensuring the precision, stability, and safety of the press. Its primary function is to provide precise motion constraints and guidance for the moving crossbeam (the main motion actuator of the hydraulic press), ensuring that the crossbeam maintains a stable posture during its reciprocating motion and preventing deviation, tilting, or swaying, thereby meeting the precision and reliability requirements of the pressing process. Currently, the guide mechanism suffers from the following generally accepted shortcomings: In traditional guide mechanisms, the friction between the inner walls of the hydraulic rods increases their heat due to repeated sliding and extension. The built-in cooling system alone cannot achieve efficient heat dissipation, thus reducing the overall effectiveness of the hydraulic rod guide mechanism. Utility Model Content
[0003] The purpose of this utility model is to provide a column guide mechanism for a hydraulic press, which aims to solve the problem that the existing technology cannot achieve more efficient heat dissipation by relying solely on its own cooling system, thereby reducing the overall performance of the hydraulic rod guide mechanism.
[0004] To achieve the above objectives, this utility model provides the following technical solution: A column guide mechanism for a hydraulic press includes a base. Four limiting rods are fixedly installed at the top of the base. A liquid storage top seat is fixedly installed at the top of the four limiting rods. A hydraulic main rod is fixedly installed at the bottom of the liquid storage top seat. A hydraulic auxiliary rod is slidably connected to the inner wall of the bottom end of the hydraulic main rod. A hydraulic plate is fixedly installed at the bottom end of the hydraulic auxiliary rod. A cooling ring is sleeved on the outer side of the hydraulic auxiliary rod. The bottom end of the cooling ring is fixedly connected to the top of the hydraulic plate. Two connecting pipes are connected to the top of the cooling ring. The outer sides of the two connecting pipes are slidably connected to the inner wall of the liquid storage top seat. A top box is connected to the top of the connecting pipes. Telescopic pipes are connected to both sides of the top box. The telescopic pipes are interconnected with the top of the liquid storage top seat.
[0005] In a preferred embodiment of this invention, two guide rods are rotatably connected to the inner wall of the liquid storage top seat, and two transition rods are also rotatably connected to the inner wall of the liquid storage top seat.
[0006] In a preferred embodiment of this utility model, a transition gear is fixedly installed at the bottom end of the transition rod, and pulleys are fixedly installed at the bottom ends of both the guide rod and the transition rod, with a belt sleeved on the outer side of the pulleys.
[0007] In a preferred embodiment of this utility model, a mounting plate is fixedly installed on the top of the liquid storage top seat. A main rotating shaft and two auxiliary rotating shafts are rotatably connected to one side of the mounting plate. A connecting gear is fixedly installed on the outer side of one of the auxiliary rotating shafts and the main rotating shaft. A drive gear is fixedly installed on the outer side of the other auxiliary rotating shaft. The connecting gear meshes with the drive gear. A bevel gear is fixedly installed on the top end of one of the transition rods and one end of the main rotating shaft.
[0008] In a preferred embodiment of this utility model, a connecting frame is fixedly installed on the outer side of the top box, and a rack is fixedly installed on the inner side wall of the connecting frame, the rack meshing with a drive gear.
[0009] As a preferred embodiment of this utility model, two limiting plates are also fixedly installed at the top of the liquid storage top seat, and the outer sides of the two limiting plates are slidably connected to the inner sidewall of the connecting frame.
[0010] Compared with the prior art, the beneficial effects of this utility model are: 1) By setting a cooling ring that follows the rise and fall of the hydraulic plate, the cooling effect on the hydraulic auxiliary rod can be maintained when the hydraulic main rod and the hydraulic auxiliary rod slide between them. It also protects the hydraulic auxiliary rod from damage caused by flying debris that may be generated during processing in the external environment, thereby improving the overall guiding mechanism's performance.
[0011] 2) The connection between the liquid storage top seat and the top box is achieved by setting a telescopic pipe, so that the cooling oil inside the cooling ring can flow into the liquid storage top seat from the connecting pipe and the top box, and the cooling oil inside the hydraulic top seat can also flow into the cooling ring, thereby playing a circulation role in the cooling oil inside the cooling ring and maintaining the continuous cooling effect of the cooling ring on the hydraulic auxiliary rod.

[0014] 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.
[0015] Please see Figure 1-5 This utility model provides the following technical solution: a column guide mechanism for a hydraulic press, including a base 1, four limiting rods 2 fixedly installed at the top of the base 1, a liquid storage top seat 3 fixedly installed at the top of the four limiting rods 2, a hydraulic main rod 4 fixedly installed at the bottom of the liquid storage top seat 3, a hydraulic auxiliary rod 41 slidably connected to the inner wall of the bottom end of the hydraulic main rod 4, a hydraulic plate 42 fixedly installed at the bottom end of the hydraulic auxiliary rod 41, a cooling ring 5 sleeved on the outer side of the hydraulic auxiliary rod 41, the bottom end of the cooling ring 5 fixedly connected to the top of the hydraulic plate 42, two connecting pipes 51 connected to the top of the cooling ring 5, the outer side of the two connecting pipes 51 slidably connected to the inner wall of the liquid storage top seat 3, a top box 52 connected to the top of the connecting pipes 51, telescopic pipes 53 connected to both sides of the top box 52, and the telescopic pipes 53 communicating with the top of the liquid storage top seat 3.
[0016] In practical use, the hydraulic auxiliary rod 41 slides inside the hydraulic main rod 4, thereby driving the hydraulic plate 42 to rise and fall. The hydraulic plate 42 slides on the limit rod 2 around its perimeter. When sliding between the hydraulic main rod 4 and the hydraulic auxiliary rod 41, the hydraulic plate 42 can simultaneously drive the cooling ring 5 to rise and fall, so that the cooling ring 5 maintains a cooling effect on the outside of the hydraulic auxiliary rod 41. The cooling oil inside the cooling ring 5 can be connected to the liquid storage top seat 3 through the connecting pipe 51, the top box 52, and the telescopic pipe 53, so that the cooling oil inside the cooling ring 5 can circulate while the hydraulic system is rising and falling, maintaining the continuous cooling effect of the cooling ring 5.
[0017] Preferably, two guide rods 31 are rotatably connected to the inner wall of the liquid storage top seat 3, and two transition rods 32 are also rotatably connected to the inner wall of the liquid storage top seat 3.
[0018] In practical use, while the lifting plate drives the cooling ring 5 to rise and fall, the connecting pipe 51 slides on the inner wall of the liquid storage top seat 3. At this time, the two transition rods 32 rotate in opposite directions, thereby driving the two guide rods 31 to rotate in opposite directions inside the liquid storage top seat 3, so that the cooling oil can circulate between the cooling ring 5 and the liquid storage top seat 3.
[0019] Preferably, a transition gear 33 is fixedly installed at the bottom end of the transition rod 32, and pulleys 34 are fixedly installed at the bottom ends of both the guide rod 31 and the transition rod 32, with a belt 35 sleeved on the outer side of the pulleys 34.
[0020] In practical use, the two transition rods 32 rotate in opposite directions through the action of the transition gear 33, while the two guide rods 31 rotate in accordance with the corresponding transition rods 32 through the action of the pulley 34 and the belt 35.
[0021] Preferably, a mounting plate 6 is fixedly installed on the top of the liquid storage top seat 3. A main rotating shaft 61 and two auxiliary rotating shafts 62 are rotatably connected to one side of the mounting plate 6. A connecting gear 63 is fixedly installed on the outer side of one of the auxiliary rotating shafts 62 and the main rotating shaft 61. A drive gear 64 is fixedly installed on the outer side of the other auxiliary rotating shaft 62. The connecting gear 63 meshes with the drive gear 64. A bevel gear 65 is fixedly installed on the top of one of the transition rods 32 and one end of the main rotating shaft 61.
[0022] In practical use, when the cooling oil inside the cooling ring 5 needs to be circulated, the main shaft 61 can be driven to rotate on the mounting plate 6 by the drive gear 64, which in turn drives the auxiliary shaft 62 to rotate through the connecting gear 63. Then, through the action of the bevel gear 65, the transition rod 32 can be driven to rotate, so that the two guide rods 31 can rotate in opposite directions inside the liquid storage top seat 3, which circulates the cooling oil inside the liquid storage top seat 3 and the cooling ring 5.
[0023] Preferably, a connecting frame 54 is fixedly installed on the outer side of the top box 52, and a rack 55 is fixedly installed on the inner side wall of the connecting frame 54, the rack 55 meshing with the drive gear 64.
[0024] In practical use, when the cooling ring 5 moves up and down with the lifting plate, the connecting pipe 51 can simultaneously cause the top box 52 to move up and down. Thus, the reciprocating movement of the top box 52 with the connecting frame 54 drives the drive gear 64. In turn, the guide rod 31 can be driven to rotate when moving up or down, so that the cooling oil between the liquid storage top seat 3 and the cooling ring 5 can be circulated back and forth.
[0025] Preferably, two limiting plates 7 are also fixedly installed at the top of the liquid storage top seat 3, and the outer sides of the two limiting plates 7 are slidably connected to the inner sidewall of the connecting frame 54.
[0026] In practical use, the limiting plate 7 can prevent the connecting frame 54 from shifting when it follows the top box 52 up and down.
[0027] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
