Abstract
The utility model discloses a four-pillar oil press, which comprises a base and a moving beam, each of the four corners of the base is fixed with a hydraulic cylinder, the four guide pillar of the moving beam are respectively connected with piston rods of the hydraulic cylinders, each of the hydraulic cylinders is hinged with a driving arm which is hinged with the guide pillar or the piston rod through a connecting rod, the two driving arm which are vertically adjacent shares a balance shaft, a linkage arm is arranged on the balance arm in a radial direction, a pulling rod is arranged between the two linkage arms which are horizontally adjacent, the two ends of the pulling rod are respectively connected with the linkage arm; the utility model of oil press has good inclined loading proof capability, and can maintain smoothness and stability of the moving beam under the condition of imbalance force processing.
Description
Technical field
The utility model relates to the hydraulic press that is used for metal plate punching and brake forming.
Background technology
Having many uses of four-column type hydraulic press in industries such as light industry, household electrical appliances, electronics, automobile, shipbuilding and construction decorations, is widely used in the punching press or the brake forming of panel beating.As shown in Figure 1, traditional hydraulic press comprises base 1, back timber 11 and walking beam 2, and the centre position between back timber and walking beam is equipped with and is used for the hydraulic cylinder 3 that the application of force drives walking beam.During processing work, workpiece is placed between base and the walking beam, and the hydraulic cylinder application of force drives walking beam workpiece is exerted pressure.If the workpiece that is stamping is bigger, and the bigger pressure of the complex-shaped need of a side, opposite side only needs less pressure, and then the both sides of walking beam are subjected to different reaction forces simultaneously, and promptly hydraulic press is in the unbalance loading machining state.Add man-hour in unbalance loading, walking beam is easy to occur tilting or vibration, influences machining accuracy.
The utility model content
It is good that the purpose of this utility model is to provide a kind of anti-bias load ability, and in the processing of any discontinuity equalization, all can guarantee the parallel and four-column type hydraulic press stably of walking beam run action.
Four-column type hydraulic press described in the utility model, comprise base and walking beam, four jiaos of base each fix a hydraulic cylinder, walking beam has four guide pillars to link to each other with the piston rod of each hydraulic cylinder respectively, the other all hinged actuating arm of each hydraulic cylinder, it is hinged that actuating arm passes through a connecting rod and each guide pillar or piston rod, vertical adjacent shared trunnion shaft of two actuating arms, radially be fixed with transmission arm on the trunnion shaft, between two laterally adjacent transmission arms pull bar is arranged, the two ends of pull bar are hinged with each transmission arm respectively.
Four-column type hydraulic press described in the utility model by the lifting of the Driven by Hydraulic Cylinder walking beam of four jiaos of bases, is exerted pressure to realize the workpiece that is opposite between base and the walking beam.If workpiece reaction force to walking beam when stressed is unbalanced, then hydraulic press is in the unbalance loading machining state.The utility model uses actuating arm, transmission arm, trunnion shaft, pull bar that each hydraulic cylinder is connected, and has formed the balanced controls that a cover is synchronized with the movement.Add man-hour in unbalance loading, hydraulic press one side is subjected to the reaction force of workpiece less, opposite side is bigger, the hydraulic cylinder travel of a wherein stressed less side has trend bigger than normal than the opposite side hydraulic cylinder travel, the power that this movement tendency produces passes to the hydraulic cylinder of a corresponding side by actuating arm, transmission arm, trunnion shaft, pull bar, has the hydraulic cylinder of trend less than normal to replenish the application of force to stroke.Because the utility model has constituted an interlock body with each hydraulic cylinder, it adds man-hour in unbalance loading, four guide pillars can forcing automatically to connect walking beam are synchronized with the movement, thereby described hydraulic press anti-bias load ability is good, can in the processing of any discontinuity equalization, can guarantee that all the walking beam run action is parallel and steady.And described hydraulic press save back timber than the traditional oils press, simplified the structure of entire equipment, alleviated weight.
Description of drawings
The master of Fig. 1 traditional oils press looks schematic diagram;
Fig. 2, Fig. 3, Fig. 4 schematic diagram of the present utility model.
The specific embodiment
As Fig. 2, Fig. 3, shown in Figure 4, four-column type hydraulic press described in the utility model, comprise base 1 and walking beam 2, four jiaos of base 1 each fix a hydraulic cylinder 3, walking beam 2 has four guide pillars 4 to link to each other with the piston rod 5 of each hydraulic cylinder 3 respectively, each hydraulic cylinder 3 other all hinged actuating arm 6, actuating arm 6 is hinged with each guide pillar 4 or piston rod 5 by a connecting rod 7, vertical adjacent two actuating arms, 6 shared trunnion shafves 8, radially be fixed with one or two transmission arm 9 on the trunnion shaft 8, between two transmission arms 9 of horizontal adjacent correspondence pull bar 10 is arranged, the two ends of pull bar 10 are hinged with each transmission arm 9 respectively.
