Abstract

The utility model relates to a hand-operated hydraulic press which comprises a machine frame, a workbench, a cushion block and a hydraulic head, etc. The workbench is hoisted by a lifting appliance on the beam, and moves along the upright post of the machine frame; a supporting object which is used for supporting the fixed workbench is arranged on the upright post; the hydraulic heads are clamped on the bottom of the beam of the machine frame. The utility model is formed by that the inner is provided with an oil channel, and the outer is provided with elements such as a storage tank, an oil cylinder, two plunger oil pumps with different actions, etc.; in this way, a relatively complete hydraulic system is formed. The utility model has the advantages of centralized device, small volume and no power needed, completing the task of pressure processing with manual operation.

Description

Hand-operated hydraulic press

The utility model relates to a kind of hand-hydraulic formula forcing press.

The hydraulic press that current China makes, its hydraulic system, power and control device bulky complex to medium or small factory backward in economy and backwoodsman and individually owned industry, are difficult to use.

The purpose of this utility model is to provide a kind of hydraulic system integrated, and volume is little, manually operated press device.

The utility model is achieved in that a frame and the workbench that can move along framework pillar, and there is the boom hoisting that promotes workbench at the two ends of housiung separator.Cushion block is arranged on the table surface, the axle of fastening of supporting table is arranged on the framework pillar, there is fluid head the housiung separator bottom surface, and fluid head has inside to be drilled with oil duct, the outside body that parts are installed.The oil storage tank that is communicated with its oil duct is arranged above the body, the oil cylinder that is communicated with its oil duct is arranged below, the gusset of oil cylinder has two plunger oil pumps that are communicated with the oil duct of oil storage tank and oil cylinder by body, the piston that the band bar is arranged in the oil cylinder, travel indicator and reset tension spring are housed on the piston rod, there is Pressure gauge the body front, and the return valve control device.

The utility model has the following advantage and effect: the conduit under fluid pressure that disperses too many levels to be connected is concentrated in the fluid head body, need not joint, volume is little, fault is little, shockproof, must power, two plunger-type fuel pumps of difference in functionality are arranged, can increase work efficiency, be fit to medium or small factory and small towns department of backwoodsman enterprise and use.

Introduce the structure of utility model in detail below in conjunction with accompanying drawing

Fig. 1 is the utility model front view;

Fig. 2 is the utility model vertical view;

Fig. 3 is that the utility model fluid head is faced the oil circuit schematic diagram;

Fig. 4 is the utility model fluid head side-looking oil circuit schematic diagram;

Fig. 5 is the utility model fluid head front view;

Fig. 6 is the cutaway view of Fig. 4 along the a-a line.

With reference to accompanying drawing: workbench (13) is arranged in the frame (1), handwheel (8) by housiung separator (6) right-hand member, the pulley (2) of rotating shaft (7) and left end, wheel shaft (3) and steel wire rope (9) lifting are moved, fasten spool (14) that supporting table is arranged on the column (12), V-arrangement cushion block (11) is arranged on the work top, clamping plate (5) and bolt (4) are clipped on the crossbeam bottom surface with fluid head (10), fluid head is a basic part with the body (20) that inside is drilled with oil duct, there is left oil duct (30) its inside, and ball valve (32) is communicated with top oil storage tank (22) and plunger-type fuel pump (19), equally, right oil duct (36) is communicated with oil storage tank and plunger-type fuel pump (24) through asking valve, this is the oil suction line of two pumps, another left oil duct (31) and ball valve (33) are communicated with plunger displacement pump (19) and oil cylinder (26), equally, another right oil duct (37) is through ball valve, be communicated with plunger-type fuel pump (24) and oil cylinder, this is the pressure oil circuit of two pumps, oil duct (38) leads to Pressure gauge, oilhole (34) and (35) are communicated with oil storage tank and oil cylinder through oil return valve seat (41) respectively, steel ball (40) is arranged in the oil return valve seat, when threaded mandrel (44) screws in, ball valve is opened, the passage of valve seat is communicated with oil cylinder with oil storage cylinder, finish oil return work.When threaded mandrel screwed out, under the pressure of spring (39), steel ball resetted, close valve, block the passage of oil cylinder and oil storage tank, piston with rod (27) is arranged in the oil cylinder, pin (28) is worn in the bottom, hang with extension spring (17) above, scale pointer (16) is housed, and piston-rod lower end has pressure head (29), and there is scale on the surface of oil cylinder, plunger-type fuel pump (19) is equipped with in the left side of oil cylinder, is handled by handle (15).Plunger-type fuel pump (24) is equipped with on the right side, is handled by handle (25), and there are Pressure gauge (21) and oil return valve handwheel (23) in the front of body.
