Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic presses, and particularly relates to a safe four-column double-acting hydraulic press. Background Art

[0002] A hydraulic press, also known as a hydraulic machine, is a mechanical device that works based on the principle of transmitting hydrostatic pressure. A hydraulic press generally consists of a mainframe, a power system, and a hydraulic control system. It generates a huge force through the hydraulic system and is used for various material forming, forging, stamping, crushing and other processing tasks. Due to its powerful force, high precision, easy operation, and strong adaptability, etc., the hydraulic press has a wide range of applications in industrial production.

[0003] In the patent with the application number 202120039657.4, a safe four-column double-acting hydraulic press is disclosed. In the disclosed hydraulic press, it is described that "by arranging a shielding mechanism on the machine body, the shielding mechanism can shield the machine body and the downward pressing mechanism, so that the debris splashing when the workpiece to be processed placed on the pressing surface breaks can hit the shielding mechanism". Although it can achieve the anti-splashing function, the shielding mechanism composed of the frame and the flexible cloth surrounds the outside of the downward pressing mechanism as a whole, which is rather troublesome during loading and unloading. Although a lifting mechanism is arranged to realize the lifting of the frame and the flexible cloth, the overall upward movement space is limited. When crushing an item with a relatively high height, it is difficult to provide enough loading height. Based on this, a safe four-column double-acting hydraulic press is proposed here. Content of the Utility Model

[0004] The purpose of the utility model is to provide a safe four-column double-acting hydraulic press to solve the above-mentioned deficiencies in the technology.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A safe four-column double-acting hydraulic press, comprising:

[0006] A pressing table, on which a downward pressing assembly is provided;

[0007] Two enclosing assemblies, which are arranged on the outer periphery of the upper end of the pressing table, and each enclosing assembly includes a fixed baffle and a movable baffle.

[0035] To enable those skilled in the art to better understand the technical solutions of the present utility model, the following will further introduce the present utility model in detail in conjunction with the drawings.

[0036] Figure 1 And Figure 2 Both are schematic diagrams of the overall structure of the present utility model. As shown in the figure, the safe four-column double-acting hydraulic press includes a pressing table 1, and a downward pressing assembly is provided on the pressing table 1. Among them, the downward pressing assembly includes:

[0037] Four guide posts 5, and the four guide posts 5 are symmetrically connected to the four corners of the upper end face of the pressing table 1;

[0038] A mounting plate 2, and the mounting plate 2 is fixed to the top ends of the guide posts 5;

[0039] Hydraulic cylinders 3, and the hydraulic cylinders 3 are installed at the middle of the upper end face of the mounting plate 2, and there are two hydraulic cylinders 3.

[0040] A pressing plate 4, and the pressing plate 4 is installed at the bottom end of the hydraulic cylinder 3. Through holes are opened at the upper end face of the pressing plate 4 near the four corners, and the guide posts 5 penetrate through the corresponding through holes

[0041] Through the above, when in use, place the item to be crushed on the pressing table 1, then start the hydraulic cylinder 3, and use the hydraulic cylinder 3 to drive the pressing plate 4 to move downward, so that the item to be crushed can be crushed between the lower end face of the pressing plate 4 and the upper end face of the pressing table 1.

[0042] Refer to Figures 1 - 3 As shown, this safe four-column double-acting hydraulic press further includes two enclosure components 6. The enclosure components 6 are arranged on the outer periphery of the upper end of the pressing table 1, and each enclosure component 6 includes a fixed baffle 61 and a movable baffle 62. A slot 611 is opened on the fixed baffle 61, and the movable baffle 62 is telescopically arranged in the slot 611, and after the movable baffle 62 is pulled out of the slot 611, the movable baffle 62 can be flipped to be perpendicular to the fixed baffle 61. A limiting component is also arranged between the adjacent ends of the two enclosure components 6. The two enclosure components 6 block on the outer periphery when crushing the item, which can play a role in blocking the splashing of the item and increase the safety of the crushing operation.

[0043] Among them, after the two enclosure components 6 are unfolded to form a four-way block, the limiting component can be used to limit the two enclosure components 6 together to increase the overall stability.

[0044] Refer to Figure 3 and Figure 7 As shown, both the upper and lower sides of one end of the movable baffle 62 are fixed with two upper and lower fixing plates 7. An activity rod 8 is hinged between two adjacent fixing plates 7. A guiding slide rod 9 penetrates through the free end of the activity rod 8. A guiding chute 10 is opened on the inner side wall of the slot 611, and the end of the guiding slide rod 9 is slidably matched with the guiding chute 10.

[0045] Through the above, by sliding the end of the guiding slide rod 9 along the guiding chute 10, the movable baffle 62 can be quickly inserted and pulled out. Among them, one end of the guiding chute 10 close to the opening of the slot 611 is directly externally connected, so that after the movable baffle 62 is pulled out, the guiding slide rod 9 is blocked by the outermost end of the guiding chute 10 to prevent the movable baffle 62 from completely detaching from the fixed baffle 61.

[0046] Among them, after the movable baffle 62 is pulled out of the slot 611, the movable baffle 62 can be flipped to 90 degrees with the fixed baffle 61 by utilizing the hinge between the fixed plate 7 and the movable rod 8, so as to achieve double-sided blocking with one enclosure assembly 6.

[0047] See also Figures 4 - 6 As shown, the limit assembly includes:

[0048] The protrusions 63 are fixed to the upper and lower ends of the side of the fixed baffle 61 facing away from the opening of the slot 611. The protrusions 63 are formed with grooves 631. A limit rod 633 is connected to the groove 631 via an elastic member. The outer end of the limit rod 633 is integrally formed into a hemispherical portion, and two protrusions 63 are provided at the upper and lower ends of each side.

[0049] The ridge 64 is fixed on the upper and lower surfaces of the movable baffle 62 near the other end, and a receiving groove is provided on the ridge 64 to match the end of the limiting rod 633, and the top height of the upper ridge 64 is higher than the upper end surface height of the fixed baffle 61.

[0050] The elastic member is a spring 632 , and in the natural state of the spring 632 , the outer end of the limiting rod 633 protrudes outward from the groove 631 .

[0051] Based on the above technical solutions, when it is necessary to crush an object, one of the enclosure components 6 is first unfolded to form a three-sided barrier, and then the object to be crushed is moved from the open end to the pressing platform 1, and then the other enclosure component 6 is unfolded to form a four-sided barrier, and the convex strip 64 is embedded between the two protrusions 63. The spring 632 is compressed, and the outer end of the limiting rod 633 retracts. When the outer end of the limiting rod 633 moves to the accommodating groove position, the spring 632 returns to its original shape, allowing the outer end of the limiting rod 633 to be embedded in the accommodating groove, which can limit the connection ends of the two enclosure components 6 to a certain extent. When one end needs to be opened, the convex strip 64 can be held by hand and forced outward to disengage the convex strip 64 from between the two protrusions 63.

[0052] Among them, when loading materials, the setting of opening one end can ensure the loading and unloading of objects of various heights without obstruction.

[0053] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
