Description

Technical Field

[0001] This utility model relates to a hydraulic ejector structure, and more particularly to a novel ejector structure with a retaining function. Background Technology

[0002] Hydraulic presses, also known as hydraulic forming presses or hydraulic forging presses, are equipment used for forming and processing various metal and non-metal materials. Hydraulic forging presses use a control system to control the hydraulic system to drive the oil cylinders and drive the upper and lower dies to complete the forging of workpieces.

[0003] Currently, most forging presses use hydraulic cylinders installed on the bottom surface of the closed forging press to push the forged workpiece out of the throat of the forging press bed by hydraulic pressure. However, it is not easy to control the time when the workpiece remains stationary after being pushed out, which is inconvenient for automation and manual clamping of the pushed-out workpiece. Utility Model Content

[0004] The purpose of this utility model is to provide a novel top material structure with a holding function that is simple in structure, easy to operate, and convenient to clamp, so as to solve the problems in the prior art.

[0005] The technical solution of this utility model is: a novel top-feeding structure with a holding function, wherein the top-feeding structure includes a cam, a roller, a first connecting rod, a second connecting rod, an oil cylinder, and a hydraulic top-feeding cylinder;

[0006] The cam meshes with the roller and drives the roller to rotate. The roller is mounted on a connecting rod one. The connecting rod one is connected to a connecting rod two. The connecting rod two is connected to a hydraulic cylinder. The hydraulic cylinder is connected to a hydraulic top-loading cylinder through an oil circuit.

[0007] Furthermore, the clockwise rotation of the cam drives the roller to rotate counterclockwise, and the roller drives connecting rod one and connecting rod two.

[0008] Furthermore, the connecting rod two is connected to the piston of the oil cylinder and drives the oil cylinder piston to perform up-and-down reciprocating motion.

[0009] The beneficial effects of this utility model are: by utilizing the cam structure, there is a pause time during which the cylinder piston remains stationary and in the ejection state, which facilitates automated and manual clamping of the ejected material. Attached Figure Description

[0010] Figure 1 This is a schematic diagram of the structure of this utility model.

[0011] In the diagram, 1 is a cam, 2 is a roller, 3 is connecting rod one, 4 is connecting rod two, 5 is a hydraulic cylinder, and 6 is a hydraulic ejector cylinder. Detailed Implementation

[0012] A novel top-feeding structure with a holding function, the top-feeding structure includes a cam 1, a roller 2, a first connecting rod 3, a second connecting rod 4, a hydraulic cylinder 5, and a hydraulic top-feeding cylinder 6;

[0013] The cam 1 meshes with the roller 2 and drives the roller 2 to rotate. The roller 2 is mounted on the first connecting rod 3. The first connecting rod 3 is connected to the second connecting rod 4. The second connecting rod 4 is connected to the oil cylinder 5. The oil cylinder 5 is connected to the hydraulic top cylinder 6 through an oil circuit.

[0014] The cam rotates clockwise, causing the roller 1 to rotate counterclockwise, and the roller 2 drives the connecting rod 3 and the connecting rod 4.

[0015] The connecting rod 4 is connected to the piston of the oil cylinder 5 and drives the piston of the oil cylinder 5 to reciprocate up and down.

[0016] The working process of this utility model is as follows: the cam 1 rotates clockwise, driving the roller 2 on the first connecting rod 3, which in turn drives the second connecting rod 4. Then the second connecting rod 4 drives the oil cylinder 5 to move up and down reciprocatingly. The oil cylinder 5 and the hydraulic ejector cylinder 6 are connected through an oil circuit. When the oil cylinder 5 moves downward, it drives the hydraulic ejector cylinder 6 to move downward, generating an upward ejector force.

[0017] The cam structure has a pause period during which the piston of cylinder 5 remains stationary and in the ejection state, facilitating automated and manual clamping of the ejected material.
