Abstract
The utility model discloses a three-way molding hydraulic machine synchronous side cylinder which is characterized by comprising a machine seat, an oil pump, a first side cylinder and a second side cylinder, wherein the first side cylinder and the second side cylinder are arranged symmetrically on the machine seat; the first side cylinder and the second side cylinder are provided with return stroke cavities with equal volume, respectively; the first side cylinder and the second side cylinder are communicated with the return stroke cavities respectively; each return stroke cavity is provided with a movable piston; two movable positions are rigidly connected by a piston rod; the two movable positions are same in size; and the movable pistons are driven by the oil pump. The three-way molding hydraulic machine synchronous side cylinder realizes the volume synchronism of the side cylinders and greatly improves the synchronism accuracy of the side cylinders when being used in the three-way hydraulic machine and is not liable to break down, and thus the quality of the produced product can be improved.
Description
Technical field
The utility model relates to a kind of three-way forming hydraulic press synchronous side cylinder.
Background technique
The three-way forming hydraulic press is the machinery for the production of product, profile demand according to product, therefore require higher to the synchronization accuracy of hydraulic press, traditional middle-size and small-size three-way forming hydraulic pressure pusher side cylinder is to be finished by synchronous valve or diverter valve synchronously, and this synchronous side cylinder synchronization accuracy is low, be prone to fault.
Summary of the invention
In view of the deficiencies in the prior art, the utility model provides the three-way forming hydraulic press synchronous side cylinder that synchronization accuracy is high, be difficult for breaking down.
The utility model takes following technological scheme to finish:
A kind of three-way forming hydraulic press synchronous side cylinder, it is characterized in that: comprise support, oil pump, the first side cylinder and the second side cylinder, described the first side cylinder, the second side cylinder symmetry are located on the support, the first side cylinder and the second side cylinder are respectively equipped with the backhaul chamber that volume equates, the first side cylinder and the second side cylinder are communicated with the backhaul chamber respectively, and each backhaul chamber is provided with moving piston, and two moving pistons are rigidly connected with piston rod, two moving piston sizes are identical, and moving piston is driven by oil pump.
The three-way forming hydraulic press synchronous side cylinder that the utility model provides, its side cylinder drives hydraulic pressure pusher side cylinder synchronously by liquid capacity, and such synchronization structure synchronization accuracy is high, be difficult for breaking down.
Description of drawings
The utility model has following accompanying drawing:
The three-way forming hydraulic press synchronous side cylinder oil channel structures schematic representation that Fig. 1 is.
Embodiment
Accompanying drawing has represented the technical solution of the utility model and embodiment, and the below further describes each details and the working principle thereof of embodiment more by reference to the accompanying drawings.
As shown in the figure, three-way forming hydraulic press synchronous side cylinder of the present utility model, comprise support, oil pump 1, the first side cylinder 2 and the second side cylinder 3, the first side cylinder 2, the second side cylinder 3 symmetries are located on the support, and the first side cylinder 2 and the second side cylinder 3 are respectively equipped with volume equal backhaul chamber 4, the first side cylinders 2 and the second side cylinder 3 and are communicated with backhaul chamber 4 respectively, each backhaul chamber 4 is provided with moving piston 5, two moving piston 5 usefulness piston rods 6 are rigidly connected, and two moving piston 5 sizes are identical, and moving piston 5 is driven by oil pump 1.
Three-way forming hydraulic press synchronous side cylinder of the present utility model, working principle is as follows: oil pump 1 drives moving piston 5 motions, because two moving piston 5 usefulness piston rods 6 are rigidly connected, so two moving piston 5 motion speed are consistent, because moving piston 5 sizes are identical, backhaul chamber 4 volumes equate, therefore discharge flow rate is consistent, so it is synchronous that the first side cylinder 2 and the second side cylinder 3 promote, so reached side cylinder synchronous effect, the utility model side cylinder synchronization accuracy is high, failure rate is low, and the quality of product of producing is better.
