Description

A kind of two-way pneumatic pressing machine
Technical field
The utility model relates to a kind of press, refers in particular to a kind of two-way pneumatic pressing machine.
Background technology
Side bearing is the vitals on the train, and train travels on bend or when passing by track switch, side bearing plays a role in preventing rollover, so the demand of side bearing is bigger.Side bearing is made up of side bearing, elastic side bearing body, side bearing wear plate, side plate etc., all is by forcing press they to be press-fited to combine.At present, the press-loading device that each factory uses has hydraulic pressure and pneumatic two kinds of forms, and hydraulic pressure press-loading device complex structure move slowlyer, and working service requires high, and external leakage is understood serious environment pollution, and equipment making and operation cost are higher; Pneumatic press also can only adopt the formal dress technology of " side bearing is following, and elastic side bearing body is last " to press-fit when press-fiting, and workpiece is in the hemi-closure space, and operation is very inconvenient when working like this; Press-fit and to use the different anchor clamps of two covers, inefficiency when disassembling side bearing.
Summary of the invention:
The utility model technical issues that need to address provide a kind of efficient, convenient, double acting and press-fit machinery.
The utility model is achieved in that
It comprises fuselage, reservoir, lever, pressure head, and fuselage is welded into the structure of single-column open type aerostatic press by steel plate, and fuselage interior is empty, and each part of machine all is loaded within the fuselage.Reservoir has two, a following fuselage interior that is positioned at press bench, the reservoir horizontal positioned is connected with lever by bearing pin on the piston rod of reservoir, the other end of lever is connected with horizontal pressure head on being positioned at workbench, and horizontal pressure head is aimed at the side of the side bearing that need press-fit.In the inside of the fuselage of forcing press, the back of workbench another typhoon cylinder is installed also, also is connected with lever on the piston rod of this reservoir, the other end of lever is connected with vertical head, vertical head be positioned at workbench top, aim at the side bearing that need press-fit.Two reservoirs are by a reversal valve control.Lever active force brachium is in by power arm.
Further improvement of the utility model is: the outside at vertical head and horizontal pressure head is respectively arranged with fairlead, is respectively arranged with position positioning step in correspondence with each other in the fairlead and on the pressure head, and ram travel is controlled by positioning step.Workbench is provided with special fixture.
Vertically press-fit and finish press-fiting of side bearing wear plate and side bearing body, level press-fits finishes press-fiting of elastic side bearing body composition and side bearing, and the operation that press-fits of vertical and horizontal direction is controlled separately by a manual rotary valve.
Of the present utility modelly press-fit operating process and be: the wearing plate and the side bearing body of side bearing are put into mobile pallet, started switch and make the vertical head compression, and elastic side bearing body press-fits and finishes like this; Then vertical head is unclamped, side bearing is put into, make horizontal pressure head compression, side bearing and elastic side bearing body are fitted in together; Vertically pressure head unclamps then, side plate is placed on the locating slot of side bearing, makes the vertical head compression, makes side plate enter the side bearing locating slot, and vertical head unclamps, and press-fits promptly to finish.
The technological progress that the utility model is obtained is:
Because two pressure heads of the present utility model lay respectively at horizontal level and the upright position above the workbench, when press-fiting side bearing, can adopt " elastic side bearing body is following; side bearing is last " reverse installation process, be convenient to the workpiece location and installation during operation, be easy to realize workpiece being exerted pressure from both direction, workpiece is in the open space simultaneously, and is easy to operate.The utility model can be exerted pressure to workpiece with vertical both direction from level, side bearing wear plate and side bearing body are formed and are press-fited operation, elastic side bearing body and side bearing and press-fit operation and can finish continuously at a station, the production efficiency height is controlled in the operation that press-fits of both direction respectively separately by a manual rotary valve.
The utility model adopts pneumatic mode, and equipment is swift in motion, and is simple in structure, safeguard easily, and reliable operation, making and use cost are also very low.
Leverage increases the reservoir power output on the one hand as the force-expanding machine structure, simultaneously by the action direction of change power, reservoir can be installed in the column reach under the workbench, and the device interior layout is more reasonable; Guiding mechanism guarantees pressure head vertically and lengthwise movement, so that pressure head can correctly compress workpiece; The location and installation of workpiece when special fixture is used to press-fit is born pressure assembling force simultaneously, and the pressing method of employing level, vertical direction bidirectional pressing, independent control can be implemented in a mold and both be used to press-fit, and is used to again disassemble.
Ram travel is not established travel switch by the control of the positioning step on the fairlead, is located at the step control ram travel on guide post, the fairlead, and simple, accurate positioning is reliable.
