Four guide columns are fixedly installed on the top of the hydraulic base. A slide frame is slidably connected to the outer side of the four guide columns. Four sets of slider bodies are slidably connected to the inner side wall of the slide frame. Each set of slider bodies consists of three slider bodies. A threaded sleeve is rotatably connected to the inner side wall of the slider body. Four threaded columns are fixedly installed on the inner side wall of the slide frame. The outer side of the four threaded columns is threadedly connected to the inner side wall of the threaded sleeve.

Description

Technical Field

[0001] This utility model belongs to the field of hydraulic press technology, specifically relating to a high-rigidity guide mechanism for hydraulic press sliders that resists eccentric loading. Background Technology

[0002] The high-rigidity guide mechanism for anti-eccentric loads on hydraulic press slides is a core functional component enhanced based on ordinary slide guide mechanisms, specifically designed for "eccentric load conditions" and "high-precision, heavy-load requirements." Its core function is to forcibly constrain the slide's motion posture when it is subjected to asymmetrical loads (eccentric loads) through extremely high structural rigidity and precise guiding capabilities. This ensures the slide maintains stable, parallel, and vertical movement, preventing offset, tilting, or deformation, while simultaneously protecting critical equipment components from damage caused by eccentric loads. It is a crucial guarantee for achieving stable processes in high-precision, heavy-load hydraulic presses (such as precision stamping, mold lamination, and composite material pressing equipment). Currently, guide mechanisms mainly suffer from the following commonly accepted shortcomings: In the traditional use of guide mechanisms in hydraulic equipment, the sliding part on the outer side of the guide mechanism column is assisted by a slider for limiting sliding. However, the position and range of the recess are different for different columns, and the position of the slider on the sliding part cannot be adjusted according to different columns, thus reducing the applicability of the overall guide mechanism. Utility Model Content

[0003] The purpose of this utility model is to provide a high-rigidity guide mechanism for hydraulic press sliders that resists eccentric loads. It aims to solve the problem in the prior art that the position and range of the recesses of different columns are different, and the position of the slider on the sliding part cannot be adjusted according to different columns, thereby reducing the applicability of the overall guide mechanism.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A hydraulic press slider anti-eccentric load high rigidity guide mechanism includes a hydraulic base. Four guide columns are fixedly installed on the top of the hydraulic base. A slide frame is slidably connected to the outer side of the four guide columns. Four sets of slider bodies are slidably connected to the inner side wall of the slide frame. Each set of slider bodies consists of three slider bodies. A threaded sleeve is rotatably connected to the inner side wall of the slider body. Four threaded columns are fixedly installed on the inner side wall of the slide frame. The outer side of the four threaded columns is threadedly connected to the inner side wall of the threaded sleeve.

[0005] In a preferred embodiment of this invention, two rollers are fixedly installed on the inner sidewall of the slider body, and rollers are fixedly installed on the outer side of the two rollers.

[0006] As a preferred embodiment of this utility model, four limiting rods are also fixedly installed on the inner sidewall of the sliding frame, and the outer sides of the four limiting rods are interlocked with the inner sidewall of the slider body.

[0007] In a preferred embodiment of this invention, a lifting plate is fixedly installed on the outer side of the sliding frame, and a hydraulic bottom rod is fixedly installed on the top of the lifting plate.

[0008] In a preferred embodiment of this invention, a hydraulic jack is slidably connected to the top end of the hydraulic base rod.

[0009] In a preferred embodiment of this invention, a hydraulic jack is fixedly installed at the top of the guide column, and the bottom of the hydraulic jack is fixedly connected to the top of the hydraulic jack rod.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1) By rotating the threaded sleeve inside the slider body, the slider body can be moved more easily on the threaded post. This allows the slider body to be moved according to the specific position required by the guide post, so that the slider body can fit more closely to the groove of the guide post for auxiliary sliding, reducing the offset of the guide mechanism.

[0011] 2) By setting the limit rods to act on the three slider bodies, the three slider bodies slide along the limit rods and the inner wall of the slide frame, further reducing the offset or tilt of the slider bodies during movement and improving the stability of the overall guiding mechanism.

[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 The present invention provides the following technical solution: a hydraulic press slider anti-eccentric load high rigidity guide mechanism, including a hydraulic base 1, four guide columns 2 are fixedly installed on the top of the hydraulic base 1, a slide frame 3 is slidably connected to the outer side of the four guide columns 2, four sets of slider bodies 4 are slidably connected to the inner side wall of the slide frame 3, each set of slider bodies 4 consists of three slider bodies 4, a threaded sleeve 41 is rotatably connected to the inner side wall of the slider body 4, and four threaded columns 5 are fixedly installed on the inner side wall of the slide frame 3, the outer side of the four threaded columns 5 is threadedly connected to the inner side wall of the threaded sleeve 41.

[0016] In practical use, when the sliding frame 3 is fitted onto the outside of the guide post 2, two of the slider bodies 4 in each group can be moved to the sides of the guide post 2 by operating the slider body 4, so that the slider body 4 fits into the groove of the guide post 2, which plays a limiting role. The middle slider body 4 moves to the middle position of the groove to assist in the limiting role, so that the sliding frame 3 can slide stably on the guide post 2. When it is necessary to adjust the position of the slider body 4, the threaded sleeve 41 on the slider body 4 can be rotated by operating the threaded sleeve 41, so that the threaded sleeve 41 can rotate outside the threaded post 5, thereby adjusting the position of the slider body 4. This improves the convenience of operation while ensuring stability.

[0017] Preferably, two rollers 42 are fixedly installed on the inner side wall of the slider body 4, and rollers 43 are fixedly installed on the outer side of the two rollers 42.

[0018] In practical use, when the slide frame 3 slides on the guide post 2, the roller 43 rotates along the outer wall of the guide post 2, so that the roller 43 rotates inside the slider body 4 through the action of the roller 42.

[0019] Preferably, four limiting rods 6 are also fixedly installed on the inner side wall of the slide frame 3, and the outer sides of the four limiting rods 6 are interlocked with the inner side wall of the slider body 4.

[0020] In practical use, the slider body 4 slides laterally on the limiting rod 6, thereby adjusting the position of the slider body 4. The limiting rod 6 can effectively keep the slider body 4 in contact with the inner wall of the slide frame 3, and the roller 43 always maintains contact with the guide post 2. The limiting rod 6 effectively prevents the slider body 4 from shifting or tilting, and improves the stability of the overall guiding mechanism.

[0021] Preferably, a lifting plate 7 is fixedly installed on the outer side of the sliding frame 3, and a hydraulic bottom rod 71 is fixedly installed on the top of the lifting plate 7.

[0022] In practical use, when the lifting plate 7 is raised and lowered by the hydraulic base rod 71, the sliding action of the sliding frame 3 on the guide column 2 can be used to assist the lifting plate 7 in raising and lowering, thereby increasing the stability of the lifting plate 7 in raising and lowering.

[0023] Preferably, a hydraulic push rod 72 is slidably connected to the top end of the hydraulic base rod 71.

[0024] In practical use, hydraulic operation is performed between the hydraulic base rod 71 and the hydraulic top rod 72, so that the lifting plate 7 can be hydraulically lifted and lowered.

[0025] Preferably, a hydraulic jack 1 is fixedly installed at the top of the guide column 2, and the bottom of the hydraulic jack 1 is fixedly connected to the top of the hydraulic jack rod 72.

[0026] In practical use, the hydraulic top seat 1 is used to fix the height position of the hydraulic top rod 72, thereby making it easier to assist in hydraulic lifting between the hydraulic top rod 72 and the hydraulic bottom rod 71.

[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.
