detailed description

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Please refer to Fig. 1, the utility model provides a technical solution: a casting and forging machine tool with a shock absorbing function, including a shell 1, the upper part of the shell 1 is interspersed with a stamping part 2, the stamping part 2 A pressure bearing plate 3 is provided below, and the pressure bearing plate 3 is embedded in the housing 1. The lower surface of the pressure bearing plate 3 is provided with a first piston rod 4 and a second piston rod 5, and the first piston rod 4 and the second piston rod 5 are all fixedly connected with the pressure bearing plate 3, and the outer surfaces of the first piston rod 4 and the second piston rod 5 are equipped with a return spring 6, and the lower end of the return spring 6 is connected with a baffle 7. The bottom end of the first piston rod 4 is provided with a first piston 8, the bottom end of the second piston rod 5 is provided with a second piston 9, and the first piston 8 is slidably installed in the first hydraulic cylinder 10 On the surface, the second piston 9 is slidably installed on the inner surface of the second hydraulic cylinder 11, the bottom ends of the first hydraulic cylinder 10 and the second hydraulic cylinder 11 are provided with conduits 12, and the conduits 12 pass through the baffle plate 7, The upper end of the conduit 12 is inserted with a liquid storage tank 13 .

Specifically, the interior of the first hydraulic cylinder 10 and the second hydraulic cylinder 11 is a trapezoidal structure, so that a flow velocity difference is generated in the hydraulic cylinders, and the pressure bearing plate 3 is weakened by the pressing force.

Specifically, the outer surfaces of the first piston 8 and the second piston 9 are provided with rubber layers, which improves the sealing performance in the hydraulic cylinder and greatly prolongs the service life of the pistons.

Specifically, the position of the liquid storage tank 13 is higher than the pressure bearing plate 3, so that the hydraulic cylinder is always filled with liquid, and the shock absorption performance of the machine tool is enhanced.

Working principle: When the stamping part 2 moves downward to process the workpiece on the pressure bearing plate 3, the pressure bearing plate 3 moves downward under the stamping force, and the return spring 6 is squeezed to generate an upward elastic force, which passes through the first piston rod 4 The first piston 8 connected to the pressure bearing plate 3 moves downward accordingly, and the second piston 9 connected to the pressure bearing plate 3 through the second piston rod 5 also moves downward accordingly, and the liquid in the first hydraulic cylinder 10 is subjected to the pressure of the second cylinder. The extrusion of a piston 8 and the extrusion of the second hydraulic cylinder 11 by the second piston 9 both flow to the reservoir 13 through the conduit 12, and the liquid passes through the trapezoidal structure in the first hydraulic cylinder 10 and the second hydraulic cylinder 11 There will be a flow velocity difference between the time and the flow through the conduit 12 to the liquid storage tank 13, which converts the punching force into kinetic energy of the liquid, thereby performing shock absorption.
