The utility model relates to the hydraulic system of the conversion of a kind of ram speed and supporting mechanism, comprise the oil cylinder A be connected on slide block, oil cylinder B and oil cylinder C, described oil cylinder B is connected with static support mechanism and safety valve by main pipe rail with oil cylinder C, described static support mechanism and safety valve by oil circuit successively with proportion-controllable flow cartridge valve, direction control mechanism A, direction control mechanism B is connected with pressure-regulating device, oil circuit between described direction control mechanism B and pressure-regulating device respectively with oil cylinder A, oil cylinder B is connected with oil cylinder C, described main pipe rail is connected with cavity of resorption pressure transducer by oil circuit.In the utility model, whole quick turn of compression shock is at a slow speed discharged stably, and release time and distance all can regulate, be used in the slide block of Different Weight and fluid flow and pressure, thus can ensure that hydraulic press realizes stable operation, meet production technology demand, ensure quality of product.
Description
Technical field
The utility model belongs to slider of hydraulic press hydraulic control machine technology field, particularly the hydraulic system of a kind of ram speed conversion and supporting mechanism.
Background technique
When slider of hydraulic press runs, single action stamping process requires the work tempo of equipment as quickly as possible, efficiency is as far as possible high, therefore improving fast downlink speed is one of means, but after raising downstream rate, will produce very large hydraulic shock when it is under slowly, when impacting frequently fierce, easily there is seepage and even have an accident in hydraulic system.
Summary of the invention
The utility model provides a kind of ram speed to change the hydraulic system with supporting mechanism for solving in known technology the technical problem that exists, when improving speed, will impact the steady release that can control, and avoiding the impact of pipeline.
The technological scheme that the utility model is taked for the technical problem existed in solution known technology is:
The hydraulic system of a kind of ram speed conversion and supporting mechanism, comprise the oil cylinder A be connected on slide block, oil cylinder B and oil cylinder C, described oil cylinder B is connected with static support mechanism and safety valve by main pipe rail with oil cylinder C, described static support mechanism is connected with proportion-controllable flow cartridge valve, direction control mechanism A, direction control mechanism B and pressure-regulating device by oil circuit successively with safety valve, oil circuit between described direction control mechanism B and pressure-regulating device is connected with oil cylinder A, oil cylinder B and oil cylinder C respectively, and described main pipe rail is connected with cavity of resorption pressure transducer by oil circuit.
The advantage that the utility model has and good effect are: in the utility model, whole quick turn of compression shock is at a slow speed discharged stably, and release time and distance all can regulate, be used in the slide block of Different Weight and fluid flow and pressure, thus can ensure that hydraulic press realizes stable operation, meet production technology demand, ensure quality of product.
Accompanying drawing explanation
Fig. 1 is the utility model hydraulic principle figure.
In Fig. 1,1. oil cylinder A, 2. main pipe rail, 3. cavity of resorption pressure transducer, 4. static support mechanism and safety valve, 5. proportion-controllable flow cartridge valve, 6. direction control mechanism A, 7. pressure-regulating device, 8. oil cylinder B, 9. oil cylinder C, 10. direction control mechanism B.
Embodiment:
For summary of the invention of the present utility model, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1, the hydraulic system of a kind of ram speed conversion and supporting mechanism, comprise the oil cylinder A1 be connected on slide block, oil cylinder B8 and oil cylinder C9, oil cylinder B8 is connected with static support mechanism and safety valve 4 by main pipe rail 2 with oil cylinder C9, static support mechanism and safety valve 4 by oil circuit successively with proportion-controllable flow cartridge valve 5, direction control mechanism A6, direction control mechanism B10 is connected with pressure-regulating device 7, oil circuit between direction control mechanism B10 and pressure-regulating device 7 respectively with oil cylinder A1, oil cylinder B8 is connected with oil cylinder C9, main pipe rail 2 is connected with cavity of resorption pressure transducer 3 by oil circuit.
When slide block fast downlink, oil cylinder hydraulic oil enters integrated valve body by main pipe rail 2 by static support mechanism and safety valve 4, then under the control of proportion-controllable flow cartridge valve 5 by hydraulic oil exits valve body, monitored in real time by pressure in cavity of resorption pressure transducer 3 pairs of main pipe rails 2, at the fast speed row be converted to descending at a slow speed after, again by the data of cavity of resorption pressure transducer 3, foundation numerical control proportion-controllable flow cartridge valve 5 sets up back pressure during work.Direction control mechanism A6, direction control mechanism B10, auxiliary fast downlink and the backhaul controlling slide block of pressure-regulating device 7.
In the utility model, whole quick turn of compression shock is at a slow speed discharged stably, and release time and distance all can regulate, be used in the slide block of Different Weight and fluid flow and pressure, thus can ensure that hydraulic press realizes stable operation, meet production technology demand, ensure quality of product.
Above embodiment is only in order to illustrate that the technical solution of the utility model is not intended to limit, and those of ordinary skill in the field should be appreciated that and still can modify to the embodiment of model utility or carry out equivalent replacement to portion of techniques feature; And not departing from the spirit of technical solutions of the utility model, it all should be encompassed in the technology of the utility model request protection.
