The utility model provides an energy-saving hydraulic press, as shown in fig. 1 to 7, which comprises a frame 1 and a sliding table 2, wherein the sliding table 2 is slidably connected to the frame 1, in this embodiment, the sliding table 2 is used for driving a lower die 01 to lift, and the lower die 01 is clamped with an upper die (not shown in the figure) after being lifted so as to punch a product, and the punching can be cutting type punching for removing a base material to obtain the product, hot pressing for preparing powder into the product, or other types of punching. For the convenience of explanation of the utility model, the energy-saving hydraulic press provided by the embodiment and the attached drawings is lifted at the bottom, so that the lower die 01 is driven to move during production; it should be understood that the energy-saving hydraulic press can also be lifted from the top, if it is lifted from the top, the upper die is driven to move during production.
The energy-saving hydraulic machine further comprises an idle hydraulic cylinder 3, a pressurizing hydraulic cylinder 4 and a clutch mechanism 5, wherein the cross section area of a piston of the idle hydraulic cylinder 3 is smaller than that of a piston of the pressurizing hydraulic cylinder 4, so that the thrust of the idle hydraulic cylinder 3 is smaller than that of the pressurizing hydraulic cylinder 4, but the expansion speed of the idle hydraulic cylinder 3 is faster than that of the pressurizing hydraulic cylinder 4 under the same flow. The cylinder body of the idle hydraulic cylinder 3 and the cylinder body of the pressurizing hydraulic cylinder 4 are fixedly connected to the frame 1, and a piston rod of the idle hydraulic cylinder 3 is connected with the sliding table 2; the clutch mechanism 5 is used for connecting a piston rod of the pressurizing hydraulic cylinder 4 with the sliding table 2, the clutch mechanism 5 has a locking state and a separating state, when the clutch mechanism 5 is in the locking state, the sliding table 2 drives the piston rod of the pressurizing hydraulic cylinder 4 to move together by means of the clutch mechanism 5, and when the clutch mechanism 5 is in the separating state, the piston rod of the pressurizing hydraulic cylinder 4 moves independently of the sliding table 2.
Based on the above configuration, when the idle stroke is required, the idle hydraulic cylinder 3 is operated and the pressurizing hydraulic cylinder 4 is in a freely telescopic state, the idle hydraulic cylinder 3 drives the sliding table 2 and the piston rod of the pressurizing hydraulic cylinder 4 to move rapidly, when the sliding table 2 moves to a position where the mold approaches to the mold closing, the operation of the pressurizing hydraulic cylinder 4 is switched, the idle hydraulic cylinder 3 does not move to support the sliding table 2, and the pressurizing hydraulic cylinder 4 drives the lower mold 01 to move to perform the punching operation.
It should be noted that, the free telescopic state mentioned in this embodiment means that the hydraulic cylinder can be driven to expand and contract by the outside in a low-resistance manner, and simultaneously the hydraulic cylinder automatically sucks and discharges hydraulic oil with lower resistance, without the assistance of a hydraulic pump or with only a small degree of assistance of the hydraulic pump. The mode of realizing the free telescopic state can be to open a limiting valve in an oil way of the hydraulic cylinder to enable the hydraulic cylinder to be communicated with an oil supply tank and enable hydraulic oil to flow freely, and the hydraulic cylinder sucks and releases the hydraulic oil freely along with the movement of the telescopic rod. Of course, the free expansion and contraction of the hydraulic cylinder is realized in the prior art, and thus will not be described in detail in the present application.
In the present embodiment, the clutch mechanism 5 includes the connection block 51, the connection seat 52, and the lock lever 53, the connection block 51 being fixedly connected with the piston rod of the pressure cylinder 4, the lock lever 53 being provided between the connection block 51 and the connection seat 52 and being capable of relatively fixing and releasing the connection block 51 and the connection seat 52. Based on the above configuration, the lock lever 53 can realize the functions required for the clutch mechanism 5 when switching the state. Preferably, the connection block 51 includes a connection plate 511 connected to a piston rod of the pressure hydraulic cylinder 4 and a plunger 512 connected to the connection plate 511, and an extending direction of the plunger 512 is parallel to a moving direction of the piston rod of the pressure hydraulic cylinder 4; the connection base 52 is provided with a first slide hole 521 through which the insertion rod 512 passes and a second slide hole 522 through which the lock rod 53 is inserted, the first slide hole 521 being penetrated by the second slide hole 522; the lock lever 53 is inserted into the second slide hole 522 and can fix and release the insert lever 512 to and from the connection base 52. After the lock rod 53 makes the insert rod 512 and the connecting seat 52 relatively fixed, the idle hydraulic cylinder 3 drives the sliding table 2 to slide, and the sliding table 2 drives the piston rod of the pressurizing hydraulic cylinder 4 to move by the transmission of the connecting seat 52, the insert rod 512 and the connecting plate 511 in sequence.
In this embodiment, the lock lever 53 is slidably connected to the second sliding hole 522, the lock lever 53 is provided with a first inclined plane 531, the insertion rod 512 is provided with a second inclined plane 5121, when the lock lever 53 slides, the distance between the first inclined plane 531 and the second inclined plane 5121 changes, and the first inclined plane 531 can abut against the second inclined plane 5121, so that the lock lever 53 can be fixed relative to the insertion rod 512 by the friction between the first inclined plane 531 and the second inclined plane 5121. Based on the above structure, when the lock lever 53 is in closer contact with the insertion rod 512, the generated friction force is larger, so that the friction force can meet the requirement of enabling the sliding table 2 to drive the piston rod of the pressurizing hydraulic cylinder 4, and such arrangement has the following advantages compared with the point-to-point insertion hole type fixation: when the energy-saving hydraulic press is provided with different dies, the connection position between the dies and the pressurizing hydraulic cylinder 4 is different, sometimes high and sometimes low, so that the initial position of the rod top of the piston rod of the pressurizing hydraulic cylinder 4 is also different, if the lock rod 53 and the insert rod 512 are fixed by adopting the jack mode, the requirement is difficult to meet because the position of the jack is fixed and only one or a plurality of jacks are provided; the inclined surface contact is adopted, and the inclined surface contact are relatively fixed by friction force, so that countless fixing points exist, and the problems can be avoided.
In this embodiment, the energy-saving hydraulic machine at least comprises two pressurizing hydraulic cylinders 4, and a clutch mechanism 5 is respectively arranged between a piston rod of each pressurizing hydraulic cylinder 4 and the sliding table 2; the clutch mechanism 5 also comprises a telescopic cylinder 54 connected to the sliding table 2, and the movable end of the telescopic cylinder 54 is connected with the lock rod 53 and drives the lock rod 53 to slide; in the two lock bars 53 between the adjacent clutch mechanisms 5, one of the lock bars 53 is provided with a T-shaped groove, and the other lock bar 53 is provided with a T-shaped block, and the T-shaped block is clamped in the T-shaped groove. The arrangement described above allows for the simultaneous control of more than two locking bars 53 using one telescopic cylinder 54, saving the number of telescopic cylinders 54. The T-shaped groove and the T-shaped block are used to connect the adjacent lock bars 53, however, the cooperation of the T-shaped groove and the T-shaped block is only a preferred mode, and a similar structure such as the cooperation of the dovetail-shaped block and the dovetail groove can be adopted to realize the connection between the adjacent two lock bars 53. Further preferably, there is a gap between the two lock bars 53 between the adjacent clutch mechanisms 5, and a strong spring is provided between the two lock bars 53, the strong spring being located in the T-shaped groove and compressed between the groove bottom of the T-shaped groove and the T-shaped block, the strong spring tending to move the two lock bars 53 away from each other. Since the lock lever 53 and the insert lever 512 are relatively fixed by friction force in the embodiment, the requirement on the relative position between the lock lever 53 and the insert lever 512 is high, if the manufacturing precision of the first inclined plane 531 or the second inclined plane 5121 is not high, the situation that the friction force between one group of the first inclined plane 531 and the second inclined plane 5121 meets the requirement and the friction force between the other group of the first inclined plane 531 and the second inclined plane 5121 is insufficient can occur; for this reason, in the present embodiment, there is provided a gap between the adjacent two lock bars 53, which enables the two lock bars 53 to move relatively, and a strong spring is provided between the two lock bars 53, so that the lock bar 53 close to the telescopic cylinder 54 is urged by the telescopic cylinder 54 to provide a sufficient friction force, and the other lock bars 53 are urged by the spring to provide a sufficient friction force.
In the present embodiment, two sets of clutch mechanisms 5 are provided between the piston rod of each of the pressurizing hydraulic cylinders 4 and the slide table 2, the two sets of clutch mechanisms 5 being disposed in tandem. The arrangement can balance the front and back, and avoid damage to parts.
In this embodiment, the energy-saving hydraulic machine includes a plurality of pressurizing hydraulic cylinders 4 and two empty-load hydraulic cylinders 3, the plurality of pressurizing hydraulic cylinders 4 are disposed in the middle of the energy-saving hydraulic machine, and the two empty-load hydraulic cylinders 3 are disposed on the left and right sides of the plurality of pressurizing hydraulic cylinders 4, respectively. Preferably, the two empty cylinders 3 are lifted synchronously, and at least one of the plurality of pressurized cylinders 4 is lifted independently. The synchronous lifting of the idle hydraulic cylinder 3 is used for ensuring the balance of the sliding table 2 during lifting and avoiding the damage of parts; while the pressurizing hydraulic cylinder 4 may have an individual working independently to perform a plurality of working processes in one hydraulic apparatus.
In summary, the energy-saving hydraulic machine does not need a hydraulic pump to supply liquid to the pressurizing hydraulic cylinder 4 when carrying out no-load travel, so that the energy consumption is reduced, the sliding speed of the sliding table 2 is faster when carrying out no-load travel, and the production efficiency is higher.
The above-described embodiments and features of the embodiments may be combined with each other without conflict.
Finally, it should be noted that the above embodiments are only for illustrating the technical solution of the present utility model, and not for limiting the scope of the present utility model, and although the present utility model has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions can be made to the technical solution of the present utility model without departing from the spirit and scope of the technical solution of the present utility model.
