Abstract
The utility model discloses an assembling structure of a mechanical press with a novel structure, which comprises a press body, a transmission portion, an eccentric gear, an oscillating bar, a slider and eccentric wheel devices. The eccentric gear is mounted on the press body and is driven to rotate by the transmission portion, the oscillating bar is hinged with the eccentric gear, the slider is connected with the oscillating bar and can slide in a guide track mounted on the press body, and the eccentric wheel devices are arranged oppositely. The press is better in integral stress effect and more reasonable in structure, simultaneously, the height of the press body is greatly reduced, the weight of the integral press is greatly lightened, rigidity and precision of the press body are increased while manufacturing cost is reduced, precisions of processed pieces are increased, and service lives of dies are prolonged.
Description
Technical field
The utility model relates to the press technologies field, particularly a kind of short fuselage, high rigidity, good, a kind of preferably new configuration punching machine of slide block movement characteristic of stress balance.
Background technology
The punching machine of home and abroad use at present mainly is configured as slider-crank mechanism.The design feature of crank block forcing press is, guide rail is arranged on the fuselage, is connected with slide block on guide rail, and an end of slide block is connected with crank by long connecting rod, and this mechanism structure is simple, makes, maintenance is all very convenient.But in use, it is big that this mechanism exists impulsive force, and vibrations are big, and noise is big, some problems such as stiffness of fuselage difference.
In order to satisfy some punching presses, deep stretching process requirement, be slide block near the speed bottom dead centre slow and near the top dead-centre speed very fast, on the basis of slider-crank mechanism, be transformed into six bars, eight bars, ten linkages, the forcing press of this class formation adapts to the sheet stamping moulding especially, technologies such as deep drawn are used for the production in enormous quantities of large-scale thin plate covering more.As the roof of car, minibus, truck, door etc.It is adapted to deep stretching process especially, and is very little in the impulsive force of stretching workspace, and the zone of operating at full capacity is long.But because the drive system structure complexity, the processing of requirement, assembling and setting precision height make the manufacturing cycle extend, and manufacturing cost improves.Because crank block forcing press drive system structure limitation makes the path increment increase of slide block be restricted, versatility can not get improving in addition.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of new configuration punching machine at the existing many deficiencies of existing machinery forcing press.
This practical technical problem to be solved can be achieved through the following technical solutions:
A kind of new configuration punching machine comprises fuselage and running part and is slidingly mounted on slide block in the guide rail of fuselage that described running part comprises flywheel, gear shaft, described flywheel driven gear axle rotation; It is characterized in that, also comprise:
One eccentric gear, this eccentric gear have an eccentric wheel part and a gear parts, and described eccentric wheel partly is installed in first copper sheathing of fuselage, described gear parts and gear shaft engagement;
One first fork that partly is connected by first connecting axle and the eccentric wheel of described eccentric gear; Described first fork connects described slide block via axis.
For guaranteeing stress balance, the utility model also comprises:
One is installed in the interior eccentric wheel of second copper sheathing of described fuselage, and the eccentric wheel of described eccentric wheel and described eccentric gear partly is positioned at the two ends of described axis, the eccentric wheel partial rotation centres of this eccentric pivot and eccentric gear;
One passes through second fork that second connecting axle is connected with described eccentric wheel; Described second fork connects described slide block via axis; Second fork and first fork are positioned at the two ends of described axis.
The eccentric wheel partial rotation center of eccentric gear described in the utility model is concentric with the pivot of gear parts.
Operation principle of the present utility model is; The gear parts of eccentric gear rotation by the gear shaft band in the running part, fork is partly swung along with the eccentric wheel of eccentric gear and is done reciprocal rectilinear motion up and down simultaneously, because the barycenter of fork is to move on same straight line, so fork will drive slide block and do and pump along with fork.Slide block of the present utility model and axis adopt the split design, be convenient to assembling, maintenance and processing, the main shaft two ends mainly are subjected to the combining ability of shearing force and bending force, so selection is convenient in the split design, make its strength character better, can guarantee that so the whole physical life and the reliability of lathe is better.
The utility model reduces its its fuselage height greatly, and complete machine weight is significantly alleviated, and when manufacturing cost reduces, and stiffness of fuselage increases on the contrary, and precision improves, to all increasing the precision and die life of workpiece.In addition because whole machine tool structure layout adopts opposed eccentric wheel and eccentric gear topology layout, make the stressed balance more of its lathe, reliably.Eccentric gear and eccentric design make its structure under the situation of weight reduction, and stressing conditions is better.Wherein the design of eccentric gear is different with the eccentric gear design of common heavy duty machine tools, the characteristics of heavy duty machine tools eccentric gear are eccentric centers of rotation has off-centre with the center of rotation of gear wheel, and in this lathe in the eccentric gear, the center of rotation and the gear wheel center of rotation of eccentric wheel part are concentric.

The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose with effect is easy to understand, below in conjunction with illustrating and the specific embodiment, further set forth the utility model.
Referring to Fig. 1, a kind of new configuration punching machine assembly structure shown in the figure, comprise fuselage 1 and running part and and be slidingly mounted on slide block 10 in the guide rail 11 of fuselage 1, running part comprises flywheel 2 and gear shaft 3, flywheel 2 drives by motor and belt gear and rotates, one end of gear shaft 3 is connected with flywheel 2, and flywheel 2 driven gear axles 3 rotate.
The eccentric wheel part 41 of eccentric gear 4 is installed in the copper sheathing 9 of fuselage 1, the gear parts 42 and gear shaft 3 engaged transmission of eccentric gear 4; Fork 5 one ends are hinged with the eccentric wheel part 41 of eccentric gear 4 by connecting axle 8, and along with the rotation of eccentric gear 4, fork 5 is done the compound motion of swing and straight reciprocating motion; The other end of fork 5 is connected with the end of slide block 10 by axis 7, and slide block 10 is followed fork 5 and moved reciprocatingly in the guide rail 11 of fuselage 1.Better in order to guarantee stressing conditions in addition, the lathe reliability is better, and opposite disposed has a copper sheathing 9a on the fuselage 1 of another side, and an eccentric wheel 6 is installed in copper sheathing 9a, fork 5a one end is hinged by connecting axle 8a and eccentric wheel 6, and the fork 5a other end is connected with the other end of axis 7.
