Abstract
The utility model relates to a hydraulic mechanical press machine, and a power device of the hydraulic mechanical press machine is composed of a plunger piston pump and a gear pump which are driven by a motor. A power transmission device is a hydraulic mechanical compound transmission device which is composed of a hydraulic oil cylinder and a toggle mechanism. A piston rod of the hydraulic oil cylinder is connected with a long toggle rod of the toggle mechanism, and a short toggle rod is connected with a press machine slide block through a connecting rod. The utility model has the advantages of a hydraulic press machine and a mechanical press machine simultaneously, and not only pressing force can be changed arbitrarily, but also overloading can not be produced. Requirements of pressure maintaining and time delay of each step in a pressing process and an accurate position of a lower dead point of the slide block can be achieved. The utility model has the advantages of novel structure, reliable performance, complete functions, high productive efficiency, etc.
Description
The utility model relates to machining equipment, particularly a kind of pressure processing machinery.
Present forcing press processing equipment, as friction press, hydraulic press, punch press etc., its power transmission mode is divided into hydraulic pressure and two kinds of machineries, and advantage is respectively arranged.But also exist the adjusting of operating pressure, operating rate, stroke range limited, can not adapt to shortcomings such as multiple processing technology requirement such as stretching, compacting, stamping-out.
The purpose of this utility model is exactly will provide a kind of to adapt to that multiple processing technology requires, multiple functional forcing press.
For this reason and the design forcing press, form by fuselage, power, actuating unit and control device, the power set of forcing press are motor-driven plunger displacement pump, gear pump, actuating unit is hydraulic pressure, the mechanical compound gearing of being made up of hydraulic jack and elbow-bar mechanism, the piston rod of hydraulic jack links to each other with the long toggle link of elbow-bar mechanism, the short toggle link of elbow-bar mechanism links to each other with the slide block of forcing press through connecting rod, and slide block slides up and down in the fuselage guide rail.
The utility model is owing to adopt hydraulic pressure and mechanical compound transmission, so have the advantage of hydraulic press and punching machine simultaneously, can change the size of press power arbitrarily, can not produce overload, can realize the pressurize and the delay requirement of each work step in the pressing process again, and the accurate location of slide block bottom dead centre.Use the arm of force reinforcement of elbow-bar mechanism to reduce the size of hydraulic jack again greatly simultaneously.
In order to realize the descending and quick return of quick idle running of slide block, Hydraulic Power Transmission System of the present utility model can have differential speed accelerating circuits, and differential speed accelerating circuits is made up of two solenoid directional control valves that connect plunger displacement pump, gear pump and hydraulic jack.
The operating pressure of the utility model hydraulic machinery forcing press, operating rate, stroke range can be regulated according to arts demand, can stretch, 3 kinds of machinings such as compacting and stamping-out.This machine novel structure, dependable performance, multiple functional, production efficiency is high, can realize the requirement of 3 kinds of working specifications such as adjusting, semi-automatic and automatic.
Embodiment describes the utility model below in conjunction with accompanying drawing.
Fig. 1 is the utility model embodiment hydraulic machinery forcing press schematic diagram.
Fig. 2 is the utility model hydraulic machinery forcing press fundamental diagram.
Fig. 3 is the utility model embodiment hydraulic schematic diagram.
As shown in Figure 1 and Figure 2, the power set of the utility model hydraulic machinery forcing press are plunger displacement pump, gear pump, hydraulic pressure, the mechanical compound gearing of actuating unit for being made up of hydraulic jack 2 and elbow-bar mechanism 10 that motor 1 drives, the piston rod 3 of hydraulic jack 2 links to each other with the long toggle link 4 of elbow-bar mechanism 10, short toggle link 11 links to each other with the slide block 7 of forcing press through adjustable connecting-rod 5, and slide block 7 slides up and down in fuselage guide rail 6.Fuselage workbench 9 the place aheads form the protection barrier by adjustable photoelectric protector 8 in forcing press the place ahead, with protection operator personal safety.
As shown in Figure 3, plunger gear duplex pump B1, the B2 of motor D driving are the power source of hydraulic system.Precursor overflow valve F1 is the safety valve of hydraulic system, and angle one-way valve F2 can stop pressure oil to flow backwards, and solenoid directional control valve F3, F4 realize the differential speed accelerating of hydraulic jack 2 jointly, make slide block 7 descending fast.Hydraulic control one-way valve F5 is used for hydraulic jack 2 pressurizes, and overflow valve F6 is used to adjust stamping-out speed.
Claims (2)
1, a kind of forcing press, form by fuselage, power, actuating unit and control device, the power set of forcing press are motor-driven plunger displacement pump, gear pump, it is characterized in that hydraulic pressure, the mechanical compound gearing of said actuating unit for forming by hydraulic jack and elbow-bar mechanism, the piston rod of hydraulic jack links to each other with the long toggle link of elbow-bar mechanism, the short toggle link of elbow-bar mechanism links to each other with the slide block of forcing press through connecting rod, and slide block slides up and down in the fuselage guide rail.
2, forcing press according to claim 1 is characterized in that the control device of said forcing press has liquid husband differential speed accelerating circuits, and the hydraulic differential speed accelerating circuits is made up of two solenoid directional control valves that connect plunger displacement pump, gear pump and hydraulic jack.
