Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic presses, in particular to an adjustable hydraulic press. Background Technique

[0002] A hydraulic press is a mechanical device that uses hydrostatic pressure to process products such as metals, plastics, rubbers, woods, powders, etc. The working principle of the hydraulic press is based on Pascal's law, that is, the property of liquid transmitting pressure in a closed container. The application of the hydraulic press is very extensive. It can not only be used for processes such as stretching, forming, and pressing of metal products, but also process non-metallic materials, such as pressing of powder metallurgy products, correction of shaft parts, press-fitting of sleeve parts, and shaping and trimming of metal products. In order to improve the material processing efficiency, a hydraulic press is needed, but the existing hydraulic presses still have the following deficiencies:

[0003] For example, the utility model with the publication number CN221437339U discloses a multi-functional hydraulic press. The utility model is guided by the hydraulic cylinder of the mounting frame and fixed by bolt one and bolt two when in different positions. The processing tool is driven by a motor to realize rotation adjustment, and punching, bending, and cutting are carried out according to the processing requirements of the product. The use function is diverse, avoiding repeated replacement of processing equipment. However, for comparison documents similar to the above application, when the existing hydraulic press is in use, since most hydraulic presses and the workbench are of an integral structure, the use height of the workbench cannot be adjusted, resulting in the hydraulic cylinder being difficult to perform punching operations within the stroke, causing problems such as a decrease in the practicability and use efficiency of the hydraulic press.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and an adjustable hydraulic press is proposed. Content of the Utility Model

[0005] The purpose of the utility model is to provide an adjustable hydraulic press to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: An adjustable hydraulic press includes a main body and an adjustment component. A control box is installed on the right side of the outer part of the main body, and a workbench is arranged at the lower end of the outer part of the main body. Adjustment components are arranged on both sides of the outer part of the main body, and the adjustment component includes a fixed block, a limit cylinder, a limit rod, a return spring, an installation chute, an installation slider, a lifting block, and a limit through hole. The limit cylinder is installed outside the fixed block, the limit rod is connected inside the limit cylinder, and a return spring is arranged in the limit cylinder outside the limit rod. An installation chute is opened at the lower end of the outer part of the main body, the installation slider is connected inside the installation chute, a lifting block is installed at the upper end of the installation slider, and limit through holes are opened on both sides inside the lifting block. A limit component is arranged at the upper end of the workbench.

[0007] Furthermore, the limiting rod and the limiting cylinder are in an embedded connection, and the limiting rod is elastically connected to the limiting cylinder through a return spring.

[0008] Furthermore, the internal dimensions of the installation chute are adapted to the external dimensions of the installation slider, and the elevation block is slidably connected to the main body through the installation slider.

[0009] Furthermore, the internal dimensions of the limiting through-hole are adapted to the external dimensions of the limiting rod, and the limiting rod is connected to the elevation block through the limiting through-hole.

[0010] Furthermore, the limiting assembly includes a mounting block, an electric telescopic rod, a clamping block and a rubber pad. The electric telescopic rod is installed inside the mounting block, the front end of the electric telescopic rod is connected to the clamping block, and a rubber pad is additionally provided outside the clamping block.

[0011] Furthermore, the limiting assembly further includes a movable slider, a limiting through-groove and a limiting cross-bar. Meanwhile, a movable slider is installed in the middle of the lower end of the clamping block. A limiting through-groove is opened in the middle of the movable slider, and the limiting cross-bar is connected inside the limiting through-groove.

[0012] Furthermore, the number of the clamping blocks is two, and the two clamping blocks are symmetrically arranged on both sides of the upper end of the workbench with respect to the front central axis of the workbench.

[0013] Furthermore, the internal dimensions of the limiting through-groove are adapted to the external dimensions of the limiting cross-bar, and the limiting cross-bar is in an embedded connection with the movable slider through the limiting through-groove.

[0014] The utility model provides an adjustable hydraulic press, which has the following beneficial effects:

[0015] 1. Through the arrangement of the adjusting assembly, when the adjustable hydraulic press is in use, the fixing block can be fixedly installed on both sides of the outside of the main body through the fastening bolts, and the limiting cylinder can be fixedly installed on the outside of the fixing block in cooperation with the fastening bolts. The limiting rod is installed inside the limiting cylinder. The return spring is used to make the limiting rod elastically connected to the limiting cylinder. The elevation block is slidably installed at the lower end of the outside of the main body by using the installation chute and the installation slider. The limiting through-hole and the limiting rod are used to prevent the elevation block from shifting during use. Similarly, the elevation blocks are stacked upward, so as to increase the overall use height of the workbench, avoid the problem that the hydraulic cylinder cannot perform stamping operations within the stroke, and improve the overall use efficiency of the hydraulic press.

[0016] 2. By setting the limiting component, when the adjustable hydraulic press is in use, the electric telescopic rod drives the clamping block to move in position, so that the clamping block limits the item to be processed. At the same time, a limiting through groove is opened inside the movable slider installed at the lower end of the clamping block, and the internal dimension of the limiting through groove matches the external dimension of the limiting cross bar. Thus, the limiting through groove and the limiting cross bar are used to increase the stability of the movable slider during the movement process, and further increase the stability of the clamping block during the movement process, avoiding the problem that when the material is too smooth, the material rolls out due to different pressing angles during the downward pressing process of the hydraulic press, resulting in injury to personnel or machines.

[0021] The following further describes in detail the embodiments of the present utility model in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0022] As Figure 1 and Figure 2As shown in the figure, an adjustable hydraulic press includes a main body 1 and an adjustment component 4. A control box 2 is installed on the right side of the outer part of the main body 1, and a workbench 3 is arranged at the lower end of the outer part of the main body 1. Adjustment components 4 are arranged on both sides of the outer part of the main body 1. The adjustment component 4 includes a fixed block 401, a limit cylinder 402, a limit rod 403, a return spring 404, an installation chute 405, an installation slider 406, a lifting block 407, and a limit through hole 408. The limit cylinder 402 is installed outside the fixed block 401, and the limit rod 403 is connected inside the limit cylinder 402. A return spring 404 is arranged in the limit cylinder 402 outside the limit rod 403. An installation chute 405 is opened at the lower end of the outer part of the main body 1, and an installation slider 406 is connected inside the installation chute 405. A lifting block 407 is installed at the upper end of the installation slider 406. At the same time, limit through holes 408 are opened on both sides inside the lifting block 407. The limit rod 403 is embedded in the limit cylinder 402, and the limit rod 403 is elastically connected to the limit cylinder 402 through the return spring 404. The internal dimension of the installation chute 405 is adapted to the external dimension of the installation slider 406, and the lifting block 407 is slidably connected to the main body 1 through the installation slider 406. The internal dimension of the limit through hole 408 is adapted to the external dimension of the limit rod 403, and the limit rod 403 is connected to the lifting block 407 through the limit through hole 408. The fixed block 401 is fixedly installed on both sides of the outer part of the main body 1 through fastening bolts, and the limit cylinder 402 is fixedly installed outside the fixed block 401 in cooperation with the fastening bolts. The limit rod 403 is installed inside the limit cylinder 402, and the return spring 404 is used to make the limit rod 403 elastically connected to the limit cylinder 402. The internal dimension of the installation chute 405 opened at the lower end of the outer part of the main body 1 matches the external dimension of the installation slider 406 at the lower end of the lifting block 407. Therefore, the lifting block 407 is slidably installed at the lower end of the outer part of the main body 1 through the installation chute 405 and the installation slider 406. The internal dimension of the limit through holes 408 opened on both sides inside the lifting block 407 matches the external dimension of the limit rod 403. Therefore, the position deviation of the lifting block 407 during use is avoided through the limit through hole 408 and the limit rod 403. Similarly, the lifting blocks 407 are stacked upward, thereby increasing the overall use height of the workbench 3 and avoiding the problem that the hydraulic cylinder cannot perform stamping operations within the stroke, and improving the overall use efficiency of the hydraulic press.

[0023] As Figures 1 to 3As shown in the figure, a limit component 5 is provided at the upper end of the workbench 3. The limit component 5 includes a mounting block 501, an electric telescopic rod 502, a clamping block 503 and a rubber pad 504. The electric telescopic rod 502 is installed inside the mounting block 501, and the front end of the electric telescopic rod 502 is connected to the clamping block 503. A rubber pad 504 is additionally provided outside the clamping block 503. The limit component 5 further includes a movable slider 505, a limit through groove 506 and a limit cross bar 507. At the same time, a movable slider 505 is installed in the middle of the lower end of the clamping block 503. A limit through groove 506 is opened in the middle of the movable slider 505, and a limit cross bar 507 is connected inside the limit through groove 506. The number of clamping blocks 503 is two, and the two clamping blocks 503 are symmetrically arranged on both sides of the upper end of the workbench 3 with the front central axis of the workbench 3 as the symmetry axis. The internal dimension of the limit through groove 506 is adapted to the external dimension of the limit cross bar 507, and the limit cross bar 507 is embedded in the movable slider 505 through the limit through groove 506. The mounting block 501 is fixedly installed on both sides of the upper end of the workbench 3 through fastening bolts, and the electric telescopic rod 502 is fixedly installed inside the mounting block 501 in cooperation with the fastening bolts. The operation of the electric telescopic rod 502 drives the clamping block 503 to move, so that the clamping block 503 limits the item to be processed, and the rubber pad 504 additionally provided outside the clamping block 503 increases the stability during the clamping process. At the same time, a limit through groove 506 is opened inside the movable slider 505 installed at the lower end of the clamping block 503, and the internal dimension of the limit through groove 506 matches the external dimension of the limit cross bar 507. Therefore, the stability of the movable slider 505 during movement is increased through the cooperation of the limit through groove 506 and the limit cross bar 507, and further the stability of the clamping block 503 during movement is increased, avoiding the problem that when the material is too smooth, the material rolls out due to different pressing angles during the downward pressing process of the hydraulic press, resulting in injuries to personnel or machines.

[0024] In summary, for the adjustable hydraulic press, during use, first, the operation of the electronic components inside the device is adjusted through the control box 2 installed on the right side outside the main body 1. The electric telescopic rod 502 operates to drive the clamping block 503 to move in position, so that the clamping block 503 limits the item to be processed, and the rubber pad 504 added outside the clamping block 503 is used to avoid loosening during the material clamping process. The limit through groove 506 and the limit cross bar 507 are used to increase the stability of the movable slider 505 during movement, and further increase the stability of the clamping block 503 during movement to prevent the material from rolling out when it is too smooth. Then, the limit rod 403 is installed inside the limit cylinder 402, and the reset spring 404 is used to elastically connect the limit rod 403 and the limit cylinder 402. The installation chute 405 and the installation slider 406 are used to slidably install the lifting block 407 at the lower end outside the main body 1 of the machine. The limit through hole 408 and the limit rod 403 are used to prevent the position deviation of the lifting block 407 during use. Similarly, the lifting blocks 407 are stacked upward to increase the overall use height of the workbench 3 and avoid the problem that the hydraulic cylinder cannot perform stamping operations within the stroke, thus improving the overall use efficiency of the hydraulic press.
