Description

Quick-make formula four column pressure machines

The utility model belongs to the press that a kind of high efficiency production is used, and specifically is meant a kind of quick-make formula four column pressure machines.

Press has long production history, when manufacture craft needs certain dwell time, when needing enough pressure again, generally selects four-column universal hydraulic press for use.Along with the development of modern technologies, require four column pressure machines to high automation degree, high efficiency development.But, the High-efficient Production of forcing press, need the fast moving movable table, thereby need the cooperation in high-capacity pump, high-pressure pump and the quick loop of hydraulic pressure, make the manufacturing cost of forcing press rise significantly, and when travel of moving bolster was longer, limit velocity did not satisfy the requirement of high-efficient production line far away.

The purpose of this utility model provides a kind of quick-make formula four column pressure machines, to solve the movable table fast moving problem of four column pressure machines, after workbench drove by the casting die closure, adopting process required pressure to be exerted pressure to pressing thing again, to reach high efficiency, requirement cheaply.

The purpose of this utility model is to realize by such technical scheme: quick-make formula four column pressure machines comprise stand arrangement, movable table fast moving device, device for exerting, four columns are housed on the following fixed station of stand arrangement, and the top of column is to go up fixed station; The fast moving device comprises a cylinder and two horizontal cylinders, cylinder block is fixed on the fixed station, the piston rod end connects goes up movable table, when piston rod stretches, last movable table can slide up and down along four columns, two horizontal cylinders are installed on the movable table, and the piston rod end of horizontal cylinder connects bracing frame, and bracing frame can be in the effect lower edge of piston rod slideway fast moving; Comprise a hydraulic jack in the device for exerting, this hydraulic jack is fixed on down in the fixed station, the oil cylinder piston boom end is connected with down movable table, following movable table can slide up and down along four columns under the effect of piston rod, and mould or quilt press object to be placed between movable table and the following movable table up and down.

Cylinder is by the pneumatic circuit air feed, and hydraulic jack is by the Hydraulic Station feed flow, and whole course of action can be by the PC Controlled by Programmable Controller, the implementation procedure automation.

Characteristics of the present utility model are:

1, aspect up and down workbench closing speed, adopts cylinder quick acting device, because pneumatic speed can be several times of hydraulic pressure speed, even tens times, therefore improved the operating efficiency of forcing press greatly.

2, after last lower table drives the mould closure, hydraulic cylinder piston rod on the following fixed station rises and is in the fine motion state, stroke is very little, need only import by hydraulic oil this moment, produces high pressure and get final product, and therefore saved high-capacity pump and energy storage equipment, and fast hydraulic pressure loop, make manufacturing cost reduce greatly, energy consumption is also saved greatly, has realized economical operation.

3, this machine is specially adapted to the big high-efficient production line of closing stroke, in addition according to different technological requirements, can install different manipulators additional on this machine, satisfies the requirement of automated production, enhances productivity, and reduces product cost.

In sum, but the advantage of quick-make formula four column pressure machines of the present utility model is up and down workbench quick-make, and high efficiency, volume is little, pressure is big, low cost of manufacture, is a kind of desirable corollary equipment of high efficiency production line.

Below in conjunction with drawings and Examples the technical solution of the utility model is described further.

Fig. 1 is the structural representation of the utility model quick-make formula four column pressure machine closure states.

The same Fig. 1 of Fig. 2 shows opening.

In the present embodiment, on last fixed station 8 cylinder 7 is housed, an end of cylinder piston rod connects goes up movable table 4, and under the effect of piston, last movable table can move down rapidly along four columns 3 of stand arrangement, makes mould 10,11 closures (as shown in Figure 1).Horizontal cylinder 6 is housed above the last movable table, piston rod one end of horizontal cylinder connects bracing frame 9, this bracing frame can move back and forth along slideway 5, when moving outside the bracing frame, last movable table 4 can be under the effect of upper cylinder piston rod the up opening (as shown in Figure 2) that is, when moving in the bracing frame 9, can accept the pressure of fixed station 8 and last movable table 4.

On the fixed station 1 hydraulic jack 2 is being housed down, mould 10,11 is placed between movable table 4 and the following movable table 12 up and down, after mould quick-make up and down, the piston rod of oil cylinder 2 is moving in movable table 12 fine motions under the up drive under the effect of hydraulic oil, is exerted pressure to pressing thing.

Be forced through in the journey at object, hydraulic oil is to the piston application of force of oil cylinder 2, by piston rod power is reached down movable table 12, mould 10,11 is to last movable table 4 about the warp, last movable table reaches fixed station 8 to bracing frame 9 application of forces, fixed station 8 carries pulling force with four columns 3 of following fixed station 1 in the connection, guarantees thus to be pressed object to be out of shape by technological requirement.

The course of work is as follows:

Referring to Fig. 1.When mould 10 and 11 or pressed object to install after, cylinder 7 tops ventilation on the last fixed station 8, piston rod drives upward, and movable table 4 is displaced downwardly to (or push down and pressed object) on the counterdie 11 fast along column 3, horizontal cylinder 6 pulling bracing frame 9 rapidly moves the arrival precalculated position to the inside along slideway 5, prepares bearing pressure.Oil cylinder 2 bottoms that be contained in down on the fixed station 1 this moment feed hydraulic oil rapidly, and 12 pairs of moulds 10 of movable table and 11 under the piston rod rising drives (or being pressed object) are exerted pressure.

Referring to Fig. 1.After finishing the requirement of process stipulation, oil cylinder 2 releases, movable table 12 fine motions were descending under piston rod drove, the horizontal cylinder 6 that is contained on the movable table 4 is released bracing frame 9 rapidly along slideway 5, go up the cylinder 7 bottoms ventilation on the fixed station then, piston rod drive to be gone up movable table 4 and is moved on rapidly along column 3, finishes a working cycles.

Quick-make four column pressure machines by pc Controlled by Programmable Controller working procedure, make that the complete machine automaticity is higher in the course of the work, satisfy the high-efficiency operation of production process with this.
