Description

Technical Field

[0001] The present invention relates to the technical field of hydraulic presses, in particular to a multifunctional combined hydraulic press. Background Art

[0002] Bellows compensator is a kind of compensation element. It uses the effective expansion and contraction deformation of its working body, the bellows, to absorb the dimensional changes of pipelines, ducts, containers, etc. caused by thermal expansion and contraction, or compensate for the axial, lateral and angular displacement of pipelines, ducts, containers, etc. It can also be used to reduce noise and vibration. It is widely used in modern industry, mainly in various pipelines. It can compensate for the thermal displacement and mechanical deformation of the pipeline and absorb various mechanical vibrations, thereby reducing the deformation stress of the pipeline and increasing the service life of the pipeline. The bellows compensator needs to use a hydraulic press to process the bellows during the production process.

[0003] Publication No. CN109807221A discloses a multifunctional combined hydraulic press, comprising a frame, a main drive cylinder, an internal rapid drive cylinder, an auxiliary drive cylinder, a movable crossbeam, a guide mechanism, a workbench, a control system, a punch, and a die. The workbench is slidably mounted at the lower end of the frame, and the movable crossbeam is mounted at the upper end of the frame and directly above the workbench. The main drive cylinder and the auxiliary drive cylinder are connected by the movable crossbeam. The piston rods of the main drive cylinder, the auxiliary drive cylinder, and the internal rapid drive cylinder have different effective areas. The piston rod of the main drive cylinder has the largest effective area, while the piston rod of the internal rapid drive cylinder has the smallest effective area. Therefore, when the hydraulic fluid flow rate is the same, the piston rod of the internal rapid drive cylinder has the largest extension, while the piston rod of the main drive cylinder has the shortest extension. Although the hydraulic press can achieve multiple working speeds under the control of the control system, the hydraulic press lacks a limiting mechanism when processing a bellows compensator, causing displacement of the bellows compensator during processing, thereby damaging the bellows compensator and causing unnecessary losses.

The first tooth plate 33 moves through the second tooth plate 35 to accommodate the moving block 342 inside the receiving block 34, thereby causing the elastic member 341 to deform, and then push the placement block 3 to a suitable position, and release the handle 322. The elastic member 341 returns to its original shape because it is not squeezed by the moving block 342, and then the second tooth plate 35 engages with the third transmission gear 181, thereby achieving a wide range of applications.

[0021] Working principle: When in use, the position of the placement block 3 is adjusted according to the specifications of the bellows compensator to be stamped, and the handle 322 is turned.

The first tooth plate 33 moves through the second tooth plate 35 to store the moving block 342 inside the storage block 34, thereby causing the elastic member 341 to deform, and then push the placement block 3 to the appropriate position, and release the handle 322. The elastic member 341 returns to its original shape because it is no longer squeezed by the moving block 342, thereby re-engaging the second tooth plate 35 with the third transmission gear 181. Then, the hydraulic cylinder 121 is activated, and the hydraulic cylinder 121 drives the L-shaped tooth plate 132 to move through the stamping plate 13.

After the stamping is completed, the hydraulic cylinder 121 is controlled to retract, and the placement block 3 can be moved out of the bottom of the stamping plate 13.

[0022] In summary, the multifunctional combined hydraulic press starts the hydraulic cylinder 121 through the cooperation of the stamping plate 13 and the screw 4.

The screw block 43 drives the arc clamping block 431 to move toward the center of the base 1, thereby achieving the limit of the bellows compensator. The fixing effect is achieved by the coordinated use of the screw block 43 and the placement block 3. Since an electric telescopic rod is provided inside the screw block 43, the surface of the electric telescopic rod is fixedly connected to the limit plate, and the limit plate is fixedly connected to a plurality of limit rods away from the surface of the electric telescopic rod. The third tooth plate 432 is slidably connected to the inner wall of the base 1, and a plurality of limit holes are opened at one end of the third tooth plate 432 close to the screw block 43. In the initial state, the limit rod is located inside the limit hole. When the placement block 3 moves to the center of the stamping plate 13, the electric telescopic rod is controlled to retract so that the limit rod moves out of the limit hole. Then, when the stamping plate 13 continues to descend, it will not drive the placement block 3 to move. When it is necessary to place the placement block 3 When it is taken out, the electric telescopic rod is controlled to extend, so that the limiting rod enters the limiting hole, thereby driving the placement block 3 to move. When the screw block 43 moves on the screw rod 4, it drives the third tooth plate 432 to move. The third tooth plate 432 drives the second transmission gear 171 to rotate on the surface of the second rotating rod 17 through the first transmission gear 161. The second transmission gear 171 drives the third transmission gear 181 to rotate on the surface of the third rotating rod 18, so that the third transmission gear 181 drives the first tooth plate 33 and the storage block 34 to move through the second tooth plate 35, thereby driving the placement block 3 to slide in the moving groove 14, thereby achieving the effect of safe loading and unloading. The plate 33 is used in conjunction with the use of the plate 33, turning the handle 322, the handle 322 drives the second gear 321 to rotate through the third turning rod 32, the second gear 321 drives the first tooth plate 33 to move, the first tooth plate 33 moves through the second tooth plate 35 so that the moving block 342 is stored inside the storage block 34, thereby causing the elastic member 341 to deform, and then push the placement block 3 to the appropriate position, release the handle 322, the elastic member 341 is not squeezed by the moving block 342 and returns to its original shape, thereby causing the second tooth plate 35 to engage with the third transmission gear 181, fixing the position of the placement block 3, thereby realizing the adjustment of the position of the placement block 3 according to the stamping position, which is convenient for use.
