Description

Technical Field

[0001] This utility model belongs to the field of hydraulic press technology, and in particular relates to a hydraulic press with a protective structure. Background Technology

[0002] A hydraulic press is a mechanical device that uses hydraulic transmission. It utilizes the force output by liquid in a closed pipeline and device to achieve mechanical motion. Chinese utility model patent CN222004535U discloses a hydraulic press with a protective structure. This structure includes a protective plate, a push block, a locking rod, and a spring. The protective plate slides between two sets of support columns, pushing the push block to move the locking rod and retract it into the protective plate. The protective plate can be moved and adjusted between the two sets of support columns. When hydraulically pressing an item, the protective plate moves to the front of the item to shield it and prevent splashing. When not in use, the protective plate is placed below the top.

[0003] However, the protective structure of the aforementioned hydraulic press mainly relies on protective plates to achieve the interception effect. However, each operation of the protective plates requires manual control by the operator, which not only increases the operational difficulty but also reduces efficiency. Furthermore, the height of the protective plates is limited, and there is only one at the front, resulting in incomplete interception and protection. Therefore, there is an urgent need to improve the existing hydraulic press and provide a hydraulic press with a protective structure that offers sufficient interception and better protection. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of the existing technology by providing a hydraulic press with a protective structure that is reasonably designed, simple in structure, convenient and efficient in operation, and has sufficient interception and better protection, thereby solving the problems existing in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A hydraulic press with a protective structure includes a base. Two guide columns are symmetrically fixed to the upper end of the base. A top seat is fixedly installed at the top of the guide columns. A hydraulic cylinder is fixedly installed in the middle of the top seat. A pressure plate is fixedly connected to the telescopic end of the hydraulic cylinder. An outer protective plate is fixedly installed at the outer edge between the top seat and the base. Two sets of protective components are symmetrically arranged in front of the outer protective plate. Each set of protective components includes an opening and closing door. The opening and closing door is located directly in front of the outer protective plate. A tempered glass panel is embedded and fixed inside the bottom end of the opening and closing door. A guide groove is opened on the side of the opening and closing door near the outer protective plate. Two sets of linkage components are respectively arranged inside the front of the left and right ends of the pressure plate. Each set of linkage components includes a round rod. The round rod is slidably installed inside the pressure plate. The front end of the round rod is guided and slidably located in the guide groove.

[0007] Preferably, the opening and closing door has two guide grooves on the side near the outer protective plate, with the guide groove located between the two guide grooves, and the two guide grooves located symmetrically at the upper and lower ends of the opening and closing door.

[0008] Preferably, guide wheels are symmetrically mounted on the outer wall of the bottom front end of both the top seat and the outer protective plate, and the guide wheels are located in the guide groove.

[0009] Preferably, the longitudinal section of the guide groove is convex.

[0010] Preferably, the guide groove includes an inclined section and a vertical section located at the bottom of the inclined section, the vertical section being connected to the inclined section.

[0011] Preferably, a control box is installed on the bottom right side of the base, and the control box is connected to the hydraulic cylinder.

[0012] Preferably, the pressure plate has grooves on the outer walls of both the left and right sides at the front end, and a bolt is threaded onto the middle of the round rod, with one end of the bolt slidingly located in the groove.

[0013] Preferably, positioning holes are provided at both the front and rear ends of the slide, and a limiting plate is fixedly sleeved on the outer side of the end of the bolt away from the round rod, and the limiting plate is engaged in the positioning hole.

[0014] Preferably, the two ends of the pressure plate are slidably sleeved on the outside of the two guide posts.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] In this invention, when the hydraulic cylinder controls the pressure plate to press vertically down along the guide post, the round rods located in front of the left and right ends of the pressure plate can compress the inclined sections of the guide grooves opened on the outer walls of the two opening and closing doors. This allows the two opening and closing doors to be compressed and slide smoothly in a direction of mutual approach under the action of the guide wheels until the two opening and closing doors are closed. When the round rods enter the vertical section of the guide grooves, the opening and closing doors can be in a stationary state when the pressure plate moves down. Compared with the prior art, this protective structure does not require manual control, is easy to operate, and the closure of the two opening and closing doors can cooperate with the outer protective plate to achieve all-round full protection, with stronger protection and better effect.

[0017] This invention allows for manual rotation of the bolt, causing it to move away from the round rod until the limiting plate disengages from the positioning hole. At this point, the bolt can be used to control the round rod to slide and retract towards the inside of the pressure plate, causing the front end of the round rod to leave the guide groove. Subsequently, the opening and closing door can be manually pulled to slide horizontally, facilitating quick disassembly of the opening and closing door and making it convenient for replacement and equipment maintenance.

Detailed Implementation

[0026] The embodiments described below are merely some embodiments of the present invention and do not represent all embodiments consistent with the present invention. Exemplary embodiments will now be described with reference to the accompanying drawings:

[0027] like Figure 1-5 As shown in the figure, the hydraulic press with protective structure of this utility model includes a base 1, an outer protective plate 4, a hydraulic cylinder 7, and a control box 12. Two guide columns 2 are symmetrically fixed on the upper end of the base 1. A top seat 3 is fixedly installed on the top of the guide columns 2. An outer protective plate 4 is fixedly installed on the outer edge between the top seat 3 and the base 1. Two sets of protective components 6 are symmetrically arranged on the front of the outer protective plate 4. The two sets of protective components 6 are linked and their sliding directions are always opposite. A hydraulic cylinder 7 is fixedly installed in the middle of the top seat 3. A pressure plate 8 is fixedly connected to the telescopic end of the hydraulic cylinder 7. The two ends of the pressure plate 8 are respectively slidably sleeved on the outside of the two guide columns 2. Two sets of linkage components 9 are respectively arranged in the front interior of the left and right ends of the pressure plate 8. The two sets of linkage components 9 are respectively connected to the two sets of protective components 6. Sliding grooves 10 are opened on the outer walls of the left and right sides of the front end of the pressure plate 8. A control box 12 is installed on the bottom right side of the base 1. The control box 12 is connected to the hydraulic cylinder 7.

[0028] As a preferred embodiment, based on the above structure, each protective component 6 further includes an opening and closing door 61, a guide groove 62, a guide groove 63, and a reinforced glass panel 64. The opening and closing door 61 is located in front of the outer protective plate 4. Two guide grooves 62 and guide grooves 63 are opened on the side of the opening and closing door 61 near the outer protective plate 4. The guide groove 63 is located between the two guide grooves 62. The two guide grooves 62 are located symmetrically at the upper and lower ends of the opening and closing door 61, respectively. The reinforced glass panel 64 is embedded and fixed inside the bottom end of the opening and closing door 61.

[0029] In this embodiment, by controlling the closure of the left and right sets of protective components 6, it is easy to cooperate with the outer protective plate 4 to achieve all-round full protection, with stronger protection and better effect.

[0030] As a preferred embodiment, based on the above structure, guide wheels 5 are symmetrically mounted on the bottom front end outer walls of the top seat 3 and the outer protective plate 4, and the guide wheels 5 are located in the guide groove 62.

[0031] In this embodiment, the guide wheel 5 facilitates the installation and stable sliding adjustment of the protective component 6.

[0032] As a preferred embodiment, based on the above structure, the longitudinal section of the guide groove 62 is convex, and the guide groove 63 includes an inclined section and a vertical section located at the bottom of the inclined section, and the vertical section is connected to the inclined section.

[0033] In this embodiment, the opening of the guide groove 63 facilitates the opening and closing adjustment of the two sets of protective components 6 by the pressure plate 8 through the linkage component 9, without the need for manual operation.

[0034] As a preferred embodiment, based on the above structure, each linkage component 9 further includes a round rod 91, a bolt 92 and a limiting plate 93. The round rod 91 is slidably installed inside the pressure plate 8, and the bolt 92 is threadedly installed in the middle of the round rod 91. The limiting plate 93 is fixedly sleeved on the outer side of the end of the bolt 92 away from the round rod 91.

[0035] As a preferred embodiment, based on the above structure, the front end of the round rod 91 is guided and slidably located in the guide groove 63, one end of the bolt 92 is slidably located in the slide groove 10, and positioning holes 11 are provided at both the front and rear ends of the slide groove 10, with the limiting plate 93 engaged in the positioning holes 11.

[0036] In this embodiment, when the limiting plate 93 is engaged in the front positioning hole 11, the extended rod 91 can be positioned, and the rod 91 can be controlled to retract toward the pressure plate 8, which facilitates the disassembly and assembly of the protective component 6 and equipment maintenance.

[0037] The working principle of this utility model is as follows:

[0038] When the pressure plate 8 moves vertically downward along the guide column 2 under the control of the hydraulic cylinder 7, the two round rods 91 on the left and right can squeeze the inclined section of the guide groove 63 opened on the outer wall of the two opening and closing doors 61, so that the two opening and closing doors 61 can slide horizontally under the pressure and move closer to each other. At the same time, the guide wheel 5 can improve the smoothness and stability of the sliding of the opening and closing doors 61. When the two opening and closing doors 61 are closed, the round rods 91 enter the vertical section of the guide groove 63. At this time, the pressure plate 8 can continue to move downward while the opening and closing doors 61 are stationary. The two opening and closing doors 61 in the closed state can cooperate with the outer protective plate 4 to achieve all-round full protection, with stronger protection and better effect.

[0039] By manually rotating the bolt 92, the limiting plate 93 is moved until it disengages from the positioning hole 11. At this point, the positioning of the round rod 91 can be released. The bolt 92 can be used to control the round rod 91 to slide and retract towards the inside of the pressure plate 8, so that the front end of the round rod 91 leaves the guide groove 63. Then, the opening and closing door 61 can be manually pulled to slide horizontally, which facilitates quick disassembly of the opening and closing door 61, making it convenient for replacement and equipment maintenance.

[0040] Compared with existing technologies such as those in the prior art, this protective structure does not require manual control and can achieve automatic opening and closing control with the operation of the hydraulic press, making it simpler to operate and more efficient.

[0041] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any equivalent changes, modifications, substitutions, and variations made by those skilled in the art based on the concept of this utility model and on the basis of existing technology through logical analysis, reasoning, or limited experiments shall be within the scope of protection defined by the claims.
