The utility model content
The utility model provides a kind of novel multi-station press structure for the problem that prior art exists, and is intended to improve offset load resistance and the punching precision of multiple position press, and makes the punching press of forcing press bottom dead centre, stretching fully.
The purpose of this utility model is to realize like this, a kind of novel multi-station press structure, comprise power transmission shaft and bent axle, described power transmission shaft is provided with flywheel, described power transmission shaft two ends are provided with pinion, described crankshaft two end respectively correspondence is provided with and the intermeshing gear wheel of pinion, be provided with successively eccentric shaft one on the described bent axle, eccentric shaft two, eccentric shaft three and eccentric shaft four, the eccentric arm of described eccentric shaft one and eccentric shaft four and eccentric angle is identical and be connected with slide block one by connecting rod respectively, described eccentric shaft two and eccentric shaft three are connected with slide block two and slide block three by connecting rod respectively, and the guide rail of described slide block two and slide block three is arranged on slide block one inside.
Adopt press structure of the present utility model, power transmission shaft and bent axle are realized closing the bilateral gear transmission by gear wheel and the pinion at two ends, make transmission more steady, strengthen the forcing press offset load resistance, guarantee punching precision, and effectively prolong the mold use life-span; The eccentric arm that is distributed in the eccentric shaft one of bent axle both sides and eccentric shaft four is identical with eccentric angle, and two point connection sliding block one, technological requirement according to each processing stations, eccentric shaft two and eccentric shaft three are selected suitable eccentric angle and eccentric arm, like this, make crankshaft two end have same off-centre and two point driving slide block one, the stressed more uniform and stable of bent axle, further guaranteed the offset load resistance of transmission system, in addition, the eccentric shaft one at two ends and eccentric shaft four require to select suitable eccentric angle with eccentric shaft two and the eccentric shaft three of centre according to processing technology, in the bent axle rotation process, each slide block arrives bottom dead centre according to the regular hour order, finishes a processing action that workpiece is continuous, makes the stretching of bottom dead centre or punching press more abundant.So compared with prior art, the beneficial effects of the utility model are: obviously improve the offset load resistance of forcing press, make forcing press more abundant in the punching press of bottom dead centre or stretching, improve the machining accuracy of workpiece, effectively prolong the mold use life-span.
For further guaranteeing the machining accuracy of workpiece, the eccentric arm of described eccentric shaft one and eccentric shaft four is R1, and the eccentric arm of eccentric shaft two is R2, and the eccentric arm of eccentric shaft three is R3, and R1＜R2＜R3.Like this, three slide blocks are installed mould at corresponding station respectively, because the eccentric arm of the eccentric shaft that is connected with each slide block and eccentric angle require to select according to the processing technology of workpiece, make each slide block successively arrive bottom dead centre by separately the characteristics of motion and time sequencing, finish three stamping procedure processes of a workpiece.Make the bottom dead centre punching press or stretch more abundant.
For making transmission system more steady, described intermeshing pinion and gear wheel are bilateral helical gear, make like this transmission system have better offset load resistance, and stable drive, and noise is low.
For further increasing stationarity and the offset load resistance of transmission system, described flywheel is arranged on the centre of power transmission shaft, is arranged with four groups of bearings that are used for support on the power transmission shaft of flywheel both sides.
For improving slide block along the kinematic accuracy of guide rail, the guide rail that is connected with described slide block one, slide block two and slide block three is the octahedral guide rail.
