Description

Gas, hydraulic press
Technical field
The utility model patent relates to technical field of forging and pressing equipment, specifically a kind of gas, hydraulic press.
Background technology
Mechanical Industry of China lathe used is at present all to drive crankshaft connecting rod system to carry out press work with large and heavy flywheel.The punch press of this form, consumptive material is many, heaviness, mechanicalness noise is large.Once in work, excess load just easily causes and cracks lathe bed, and punch press is scrapped.
Summary of the invention
The purpose of this utility model, is just to provide a kind of novel forging equipment-gas, hydraulic press.The utility model changes the flywheel of original punch press, the type of belt drive of crankshaft connecting rod system is air pressure, hydraulic drive form.Gas, hydraulic press consumptive material are few, and manufacturing process is simple, low cost of manufacture.In use, noise is little, even excess load can not crack lathe bed yet in work.
The purpose of this utility model is achieved in that gas, hydraulic press, it is characterized in that, there is nut at four root post two, bottom girder and back timber are fixed on respectively bottom and the top of four root posts with nut, nitrogen compression cylinder is arranged on above back timber, two one-way hydraulic oil cylinders are arranged on respectively the both sides of frame bottom girder, and the cylinder piston rod of two one-way hydraulic oil cylinders withstands on respectively the below, two ends of drift; Drift is provided with four fairleads, and fairlead is enclosed within respectively on four columns, and can slide up and down along four back timbers; Nitrogen compression cylinder piston rod connect drift above, and can push drift and move downward.The hydraulic oil of Hydraulic Station feed is through 3-position-3-way electro-hydraulic directional valve, and on year-on-year basis with compressing into out the unidirectional oil cylinder of two hydraulic pressure, punch press completes the punching press action of drift jack-up and whereabouts by one-way hydraulic oil cylinder and nitrogen compression cylinder piston movement.The electrical apparatus control system of this gas, hydraulic press is provided with two travel switches, and travel switch is communicated with and instruction electro-hydraulic directional valve, and when drift falls to touching after the travel switch of below, during electro-hydraulic directional valve returns at once, drift stops action.
Gas described in the utility model, hydraulic press also can be transferred on automatic transmission, and drift can be under the control of these two travel switches, upper and lower continuous action.
Gas described in the utility model, hydraulic press are simple in structure, rationally distributed, and steel consumption is few, low cost of manufacture.Due to the descending employing nitrogen of punch press compression cylinder piston boosting, can produce larger impulse force than hydraulic cylinder.Meanwhile, method of operating is easy flexibly, and mechanicalness noise is little, is a kind of comparatively desirable pressing equipment.
Brief description of the drawings

Fig. 3 is the hydraulic schematic diagram of this gas-liquid punch press
In figure, 1-bottom girder, 2-one-way hydraulic oil cylinder, 3-drift, 4-back timber, 5-nitrogen compression cylinder, 7-drift fairlead, 8-cylinder piston rod, 9-electro-hydraulic directional valve, 10-column, 11-nitrogen compression cylinder piston rod.
Detailed description of the invention:
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is illustrated.
Gas, hydraulic press, as shown in Figure 1, 2, 3, there is nut 6 at four root post 10 two, and bottom girder 1 and back timber 4 are fixed on respectively bottom and the top of four root posts 10 with nut 6, form integral-rack.Nitrogen compression cylinder 5 is arranged on above back timber 1, and two one-way hydraulic oil cylinders 2 are arranged on respectively the both sides of frame bottom girder 1, and the cylinder piston rod 8 of two one-way hydraulic oil cylinders 2 withstands on the below, two ends of drift 3.Drift 3 is provided with four fairleads 7, and fairlead 7 is enclosed within respectively on four columns 10, and can slide up and down along four back timbers 4.Nitrogen compression cylinder piston rod 11 connect drift 3 above, and can push drift 3 and move downward, or move upward under drift 3 pushes.Nitrogen compression cylinder piston rod 11 is by drift 3 jack-up when up, and the nitrogen in nitrogen compression cylinder is compressed.In the time that drift 3 is descending, it is afterburning descending that the piston 11 of nitrogen compression cylinder promotes again pressure head 3.Now, the punching shear that produces punch press together with the nitrogen compression thrust of cylinder piston rod 11 and the descending gravity of drift 3 is carried out punching.
As shown in Figure 3, the electrical apparatus control system of this gas, hydraulic press is provided with two travel switches, and travel switch is communicated with and instruction electro-hydraulic directional valve 9, in the time of the descending shake-up travel switch of drift 3, electro-hydraulic reversing valve 9 commutates, and the piston rod 10 of two unidirectional oil cylinders 2 is by drift 3 jack-up.In the time that drift 3 goes upward to assigned address, the travel switch of top is again in instruction electro-hydraulic directional valve 9 times, and drift 3 stops.In the time that electric pushswitch is adjusted at automated location, drift 3 can be under the control of two travel switches, forms punching action continuously up and down.
