Embodiment Construction

[0011] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0012] Such as figure 1 As shown, the worktable 2 is supported on the bench 1 of the workbench, and the supporting plate 3 is arranged at the lower part of the bench 1 of the workbench, that is, the lower part of the working table, and the supporting plate 3 and the working table 2 are connected by a hydraulic cylinder 5. The ejector pin 4 is arranged on the plate, and the ejector pin hole 6 is arranged on the working table corresponding to the ejector pin. After the stamping is completed, the hydraulic cylinder 5 drives the supporting plate 3 to move upward, and the ejector pin 4 penetrates the ejector pin hole 6 and inserts it into the lower mold. The stamping parts are ejected.

[0013] Such as figure 2 As shown, the driving hydraulic oil of the hydraulic cylinder 5 is supplied by the oil outlet 11 of the progressive distributor. In this embodimen...

Abstract

The technology of the invention belongs to the technical field of a pressing machine. In order to solve the technical problem that when a supporting plate is lifted, the inconsistent movement of hydraulic cylinders results in the inclination of the supporting plate, the invention adopts the following technical scheme: a synchronous supporting plate jacking device of a moving workbench of the pressing machine comprises the supporting plate, four hydraulic cylinders and a hydraulic pump, wherein the four hydraulic cylinders are fixed with four corners of the supporting plate, and the hydraulic pump supplies oil to the hydraulic cylinders; the synchronous supporting plate jacking device is characterized in that the hydraulic pump is connected with an oil inlet of an increment type distributor by a main oil pipe; four oil outlets of the increment type distributor are respectively with the four hydraulic cylinders by oil distributing pipes; and a one-way valve is arranged between each oil distributing pipe leading to the hydraulic cylinder and the main oil pipe. After the structure is adopted, the movement of the four cylinders is basically consistent, and the supporting plate is lifted and moves stably.

Description

technical field [0001] The technology of the invention belongs to the technical field of presses, and specifically refers to a synchronous device for jacking up a supporting plate of a movable workbench of a press. Background technique [0002] The structure of the press mobile workbench widely used in the market is that the workbench is supported on the workbench, and the supporting plate is set at the lower part of the workbench, that is, the lower part of the workbench. The hydraulic cylinder is connected, the hydraulic cylinder is fixed to the worktable, and the piston rod of the hydraulic cylinder is fixed to the supporting plate, and the action of the hydraulic cylinder drives the supporting plate to move up and down. There is a ejector pin on the supporting plate, and a ejector pin hole is provided on the working table corresponding to the ejector pin. When the supporting plate moves upward, the ejector pin on it can pass through the ejector pin hole on the working ta...
