Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic presses, in particular to a hydraulic press structure with an extended stroke. Background Art

[0002] A hydraulic press is a mechanical device that uses the hydraulic principle to transfer energy. It uses the hydraulic pressure generated by the hydraulic system to achieve processing operations such as forming, pressing, punching and shearing of workpieces. When the hydraulic press is in use, friction will be generated between the hydraulic plate and the support column due to the limit function. This friction causes great damage and wear to the machine itself, and seriously affects the service life of the equipment. Lubricating oil is manually applied to the connection between the support column and the hydraulic plate to reduce the friction between the two. However, in actual applications, manual application of lubricating oil requires frequent observation of the oil amount between the two, so it is cumbersome, and manual operation is also inefficient.

[0003] The utility model with announcement number CN219473389U discloses a lubrication structure for a hydraulic press. When the lubrication structure for the hydraulic press is in use, the lubricating oil inside the oil pump flows into the interior of the air bag through the oil inlet pipe, and then the air bag soaks the sponge through the oil outlet pipe. Therefore, when the hydraulic plate moves up and down on the outer end of the support column, the sponge with lubricating oil fits the support column, and the lubricating oil is applied to the outer end of the support column, so that the support column and the hydraulic plate have better lubrication during friction.

[0004] When the above-mentioned hydraulic press is in use, the hydraulic plate is movably installed in the middle of the support column, and the hydraulic plate moves up and down at the outer end of the support column. The workpiece is processed by the hydraulic plate, but the temperature of the hydraulic oil will rise during processing. Excessive hydraulic oil will accelerate the aging of the seal, resulting in poor use effect. Utility Model Content

[0005] The utility model provides a long-stroke hydraulic press structure, aiming to solve the problems raised in the above-mentioned background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A structure of an extended-stroke hydraulic press comprises a base, a top plate movably provided on the top of the base, a hydraulic cylinder body is fixedly installed on the top plate, an oil pipe is fixedly connected to one side of the hydraulic cylinder body, a hydraulic plate is fixedly installed at the bottom end of the hydraulic cylinder body and at a position located at the bottom of the top plate, support columns are fixedly connected at the four corners of the bottom end of the top plate, and the bottom ends of the four support columns penetrate the hydraulic plate and are fixedly connected to the four corners of the top end of the base, a mounting frame is movably provided on one side of the base, and a hair dryer is movably provided inside the mounting frame.

[0008] Furthermore, an adjustment component is provided in the mounting frame, and the adjustment component includes a screw rod and a slider.

[0010] Furthermore, a handle is movably provided at the bottom of the sliding block, and the handle is fixedly mounted on the screw rod.

[0011] It can be seen that in the above technical solution, it is convenient to drive the screw rod to rotate.

[0012] Furthermore, a punching head is movably arranged at the center position of the bottom end of the hydraulic plate, four bolts are arranged on the punching head, and the punching head and the hydraulic plate are fixed by the four bolts.

[0013] It can be seen that in the above technical solution, the fixation between the punch head and the hydraulic plate is released by bolts, and the punch head is inspected and replaced.

[0014] Furthermore, a support plate is movably provided at the center position of the top end of the base.

[0015] It can be seen that in the above technical solution, the workpiece is placed on the support plate, and the support plate can support the workpiece.

[0016] Furthermore, the bottom end of the support plate is fixedly connected with a rotating shaft, the bottom end of the rotating shaft is fixedly mounted with a motor, and the bottom end of the motor is fixedly mounted inside the base.

[0017] It can be seen that in the above technical solution, the motor is started, and the motor drives the shaft to rotate, thereby driving the support plate to rotate, and then driving the workpiece to rotate. There is no need to manually adjust the position of the workpiece, which effectively reduces the labor intensity of the staff.

[0018] Furthermore, side panels are fixedly connected to both sides of the base, and the bottom end of the mounting frame is fixedly connected to one of the side panels.

[0019] It can be seen that in the above technical solution, the stability of the base can be improved by providing two bases.

[0020] The utility model has the following advantages:

[0021] 1. The utility model drives the hydraulic plate downward through the operation of the hydraulic cylinder body, and the four support columns limit the hydraulic plate, thereby improving the stability of the hydraulic plate. At the same time, the four support columns can increase the stroke of the hydraulic plate, which can adapt to the processing of workpieces of larger sizes. At the same time, the hydraulic plate can drive the punch head to move downward, and the punch head punches the workpiece, and the hair dryer is started. The hair dryer generates wind, and the wind dissipates the heat of the hydraulic cylinder body to prevent the temperature of the hydraulic oil from being too high. The operation is simple, the seal is not easy to age, and the use effect is good;

[0022] 2. The utility model drives the screw rod to rotate by rotating the handle. Since the slider is threadedly connected to the screw rod and the mounting frame limits the rotation of the slider, the screw rod can drive the slider to move upward, thereby driving the hair dryer to move upward. Similarly, reversing the handle can drive the hair dryer to move downward. The position of the hair dryer can be adjusted according to needs, and the application range is wide.

[0032] Furthermore, an adjustment component 9 is provided in the mounting frame 10, and the adjustment component 9 includes a screw rod 901 and a slider 902.

[0033] Among them, rotating the handle 903 drives the screw rod 901 to rotate.

The hydraulic cylinder body 5 drives the hydraulic plate 3 to move downward, and the four support columns 2 limit the hydraulic plate 3, thereby improving the stability of the hydraulic plate 3. At the same time, the four support columns 2 can increase the stroke of the hydraulic plate 3, and can adapt to the processing of workpieces of larger sizes. At the same time, the hydraulic plate 3 can drive the punch head 13 to move downward, and the punch head 13 punches the workpiece. The hair dryer 14 is started, and the hair dryer 14 generates wind. The wind dissipates the heat of the hydraulic cylinder body 5 to prevent the temperature of the hydraulic oil from being too high. The operation is simple, the seals are not easy to age, and the use effect is good.
