Problems solved by technology

[0002] At present, the general hydraulic machines on the market directly drive the transmission plate to output through the oil cylinder. Since the oil cylinder directly acts on the transmission plate, the force output by the transmission plate is actually equal to the force pushed out by the oil cylinder. There is nothing you can do; in addition, since the oil cylinder only acts on one point of the transmission plate, when the transmission plate acts on other workpieces, the pressure obtained by this workpiece will also be unbalanced

Embodiment Construction

[0010] Such as figure 1 As shown, the four-column hydraulic press includes an upper fixed plate 11, a lower fixed plate 13, and a movable plate 12. The upper fixed plate 11 and the lower fixed plate 13 are fixedly connected by four columns 14, and the movable plate 12 is located between the upper and lower fixed plates 11, 13. and can slide up and down along the column 14, these are all prior art; in addition, the hydraulic machine also includes an oil cylinder 1 and a transmission mechanism, the transmission mechanism is installed between the upper fixed plate 11 and the movable plate 12, through the output of the oil cylinder 1, The transmission mechanism can drive the movable plate 12 to move up and down, thereby exerting pressure on the workpiece located between the movable plate 12 and the lower fixed plate 13 .

[0011] The transmission mechanism includes upper and lower transmission plates 7, 6 (the upper and lower transmission plates 7, 6 are fixedly connected to the u...

Abstract

The invention relates to a four-column hydraulic press capable of increasing output power manyfold on the basis of an existing oil cylinder. The four-column hydraulic press comprises the oil cylinder installed on a connecting plate. The four-column hydraulic press is characterized in that the hydraulic press further comprises articulated arm units, upper transmission plates and lower transmission plates, each articulated arm unit comprises an articulated block, an upper connecting arm and a lower connecting arm, each upper connecting arm and the corresponding lower connecting arm are hinged to the corresponding articulated block, three rows of articulated arm units are hinged between the upper transmission plates and the lower transmission plates, two or more articulated arm units are arranged in each row, the articulated blocks of the articulated arm units in the middle row are in transmission connection with a telescopic rod of the oil cylinder, the articulated blocks of the articulated arm units in the left row are fixedly connected to a left connecting rod, the articulated blocks of the articulated arm units in the right row are fixedly connected to a right connecting rod, and one end of the left connecting rod and one end of the right connecting rod are fixedly connected to the connecting plate. The four-column hydraulic press can increase the power output by the transmission plates manyfold according to the lever principle, the degree of balance is high during power output, and meanwhile manufacturing cost and use cost can be greatly reduced.

Description

technical field [0001] The invention relates to a power output and transmission machine, in particular to a four-column hydraulic machine. Background technique [0002] At present, the general hydraulic machines on the market directly drive the transmission plate to output through the oil cylinder. Since the oil cylinder directly acts on the transmission plate, the force output by the transmission plate is actually equal to the force pushed out by the oil cylinder. Nothing can be done; in addition, because the oil cylinder only acts on one point of the transmission plate, when the transmission plate acts on other workpieces, the pressure obtained by this workpiece will be uneven. Contents of the invention [0003] In view of the deficiencies in the prior art, the present invention provides a four-column hydraulic press that can double the output force on the basis of the existing oil cylinder. In that: the hydraulic press also includes an articulated arm unit and an uppe...
