A hydraulic station is used to provide power, pressure is amplified through the hydraulic cylinder and then acts on a workpiece through the piston, flow of hydraulic oil is controlled through a three-position four-way valve, downward pressing speed of the workpiece is adjusted, and the direction of the hydraulic oil is adjusted through the three-position four-way valve to achieve circulated extrusion of the workpiece. The gantry press with the worktable capable of ascending and descending is compact in structure, strong in rigidity, stable and reliable in work, simple to operate and high in automatic degree.
Description
Technical field
The utility model relates to machine-building equipment technology field, especially a kind of workbench liftable portal-type hydraulic press equipment.
Background technology
In machinery production manufacturing field, especially in mechanical High Accuracy Constant Temperature assembling process, need the parts of interference or interference fits assembling quite a lot of.Usually adopt hammer to knock or forcing press such as is pressed at the method.But following drawback can occur: 1, the employing hammer knocks the assembly precision reduction that can cause parts, temperature raises, the series of problems such as bump injury parts, and production efficiency is low, both waste a large amount of costs of labor, also virtually increased the production cost of enterprise; 2, in the prior art, shape, the specification of forcing press are more complete, but can not realize the liftable hydraulic press of workbench, in the mechanical part assembling process, especially in nonstandard metallurgical parts assembling process, the height of workpiece is inconsistent to be occurred often, a conventional forcing press is difficult to satisfy the needs of assembling, for satisfying the extruding to the different size parts, manufacturer adopts the forcing press of many different sizes to realize the assembling of product, and production cost increases relatively.Thereby it is very large to design the liftable forcing press meaning of workbench.
Summary of the invention
For overcoming the deficiencies in the prior art, goal of the invention of the present utility model is to provide a kind of workbench liftable gantry-type press, take hydraulic pressure as power source, by hydraulic cylinder hydraulic pressure is converted to pressure to workpiece, realizes the forcing press function; Realize the elevating function of workbench by elevating mechanism, only adopt the forcing press can be to the press fit purpose of differing heights size workpiece to reach.
For achieving the above object, gantry type frame of the present utility model is connected with screw bolt seat with alignment pin, alignment pin is contained in the keyway of adjusting screw rod, the rotation screw that handle is housed is connected with screw bolt seat, the rotation screw is connected with the adjustment screw rod by screw thread, adjusts screw rod and fixes through rebound and workbench, and workbench is connected with gantry stand by bearing pin, hydraulic cylinder is installed in the seat hole of gantry stand, and the binder dish is connected with the piston of hydraulic cylinder.
The utility model adopts Hydraulic Station that power source is provided, after the amplification of hydraulic cylinder realization pressure, through piston rod pressure-acting is carried out press fit at workpiece, flow by three-position four-way valve control hydraulic oil, regulating the speed that presses down to workpiece, the direction by three-position four-way valve regulator solution force feed is to realize the cycle extrusion of workpiece.Hydraulic cylinder is installed on the gantry stand, workbench is installed on the frame by elevating mechanism, rotary handle in the rotary lifting mechanism, alignment pin makes the adjustment screw rod remain static at circumferencial direction, thereby the circular motion that will rotate screw is converted to the axial displacement (moving up and down) of adjusting screw rod, workbench is connected to the top of adjusting screw rod by rebound, thereby has realized the elevating function of workbench.After reaching the working depth that needs, workbench is fixed together with bearing pin and frame, according to suitable size range punching, can satisfy the extruding needs of differing heights size workpiece on frame.
The utility model has compared with prior art realized only adopting a forcing press to adopt gantry type frame to the press fit function of differing heights size workpiece by liftable workbench, makes whole compact equipment, and rigidity is strong, and working stability is reliable; Adopt three-position four-way valve can realize the speed that presses down of forcing press and the control of cycle extrusion.Simple to operate, automaticity is high.This forcing press also can be used as common cylindricality platform forcing press, is widely used.
Description of drawings
Fig. 1 is structural representation sketch of the present utility model.
The specific embodiment
As shown in Figure 1, gantry type frame 3 is connected with screw bolt seat 10, alignment pin 9 is installed on the screw bolt seat 10, alignment pin 9 is installed in the keyway of adjusting screw rod 6, the screw rod 6 circumferential frees degree are adjusted in restriction, rotation screw 7 is connected with screw bolt seat 10, rotation screw 7 is equipped with handle 8, rotation screw 7 is connected with adjustment screw rod 6 by screw thread, it is fixing with workbench 4 through rebound 5 to adjust screw rod 6, and workbench 4 is connected with gantry stand 3 by bearing pin 12, and hydraulic cylinder 1 is installed in the seat hole of gantry stand 3, binder dish 2 is connected with the piston of hydraulic cylinder 1, and three position four-way directional control valve 11 is flexible by Hydraulic Station 13 control hydraulic cylinders 1 piston.
The utility model is as a kind of workbench liftable portal-type hydraulic press device, by the press fit of following process implementation to workpiece.Before forcing press work, first select the suitable height of workbench 4 according to the height of workpiece, rotary handle 8, fine setting workbench 4 height, make bearing pin 12 axially be in free state, extract both sides bearing pin 12, make workbench 4 be in relative free state with gantry stand 3 above-below directions, rotary handle 8, workbench 4 is moved up and down in the gathering sill of gantry stand 3, adjust to the corresponding pin-and-hole position of workbench 4 and gantry stand 3, insert bearing pin 12, prevent that workpiece is not placed on the center of workbench 4 and makes workbench 4 and the depth of parallelism of bottom surface change rotary handle 8 in the forcing press course of work, upwards finely tune workbench 4, make adjustment screw mandrel 6 that certain pretightning force axially arranged, the pin-and-hole of workbench 4 bears upward force with respect to bearing pin 12 simultaneously, and adjustment screw mandrel 6 and bearing pin 12 bear operating pressure jointly when guaranteeing forcing press work, improve simultaneously the stability of workbench 4 in the course of work, do not deform.After workbench 4 was adjusted to the right place, opening power started Hydraulic Station 13, realized press fit to workpiece by the handle of adjusting three position four-way directional control valve 11.
