Description
Technical Field
[0001] This utility model relates to the field of casting and forging forming machine technology, and in particular to an oil discharge buffer mechanism for casting and forging forming machine. Background Technology
[0002] During the operation of a casting and forging machine, the internal hydraulic system performs an oil discharge operation after each casting and forging operation. Existing oil discharge methods are relatively simple and direct. When a large amount of oil is discharged rapidly, it generates significant pressure shocks within the discharge pipeline. This not only easily leads to wear and leakage in the discharge pipeline, shortening its service life, but may also cause vibrations to other components connected near the discharge pipeline, thus affecting the overall stability and processing accuracy of the casting and forging machine. Furthermore, in the traditional oil discharge process, the oil flow rate is difficult to control effectively, which is detrimental to subsequent oil recovery and treatment. Utility Model Content

[0014] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.
[0015] Please see Figure 1-5 This utility model provides a technical solution: an oil discharge buffer mechanism for a casting and forging forming machine, including an oil discharge cylinder 1, an oil inlet pipe 2 fixedly installed on one side of the oil discharge cylinder 1, an oil outlet pipe 3 fixedly installed on the other side of the oil discharge cylinder 1, a lower sealing cover 4 threadedly installed at the bottom of the oil discharge cylinder 1, an upper sealing cover 5 threadedly installed at the top of the oil discharge cylinder 1, a fixing plate 6 fixedly installed on the inner wall of the oil discharge cylinder 1, and also includes a buffer assembly installed inside the oil discharge cylinder 1, the buffer assembly being used to reduce the pressure impact generated during oil discharge, and a flow rate control assembly installed inside the oil discharge cylinder 1, the flow rate control assembly being used to control the hydraulic oil flow rate.
[0016] Furthermore, the buffer assembly includes a piston 10 and a damper 11. The piston 10 is slidably mounted on the inner wall of the oil discharge cylinder 1, and the damper 11 is threadedly mounted on the bottom of the upper sealing cover 5. The free end of the damper 11 is threadedly mounted on the top of the piston 10. When a large amount of oil is discharged rapidly, pressure will be generated in the oil discharge pipeline. The pressure will push the piston 10 upward, and the upward movement of the piston 10 will press the damper 11. The damper 11 buffers the piston 10, reduces the pressure impact generated during oil discharge, protects the oil discharge pipeline and surrounding components, extends the service life of the casting and forging forming machine, and also prevents other components near the oil discharge pipeline from vibrating, thereby improving the overall stability and processing accuracy of the casting and forging forming machine.
[0017] Furthermore, the flow rate control assembly includes a rotating shaft 14, a rotating plate 15, a worm gear 16, a motor 17, and a worm 18. The rotating plate 15 is sleeved on the outer wall of the rotating shaft 14, the worm gear 16 is fixedly installed on the outer wall of the rotating shaft 14, the motor 17 is fixedly installed on one side of the outer wall of the oil discharge cylinder 1, and the worm 18 is rotatably installed on both sides of the oil discharge cylinder 1. The output shaft of the motor 17 is fixedly installed on one end of the worm 18, and the worm 18 meshes with the worm gear 16. When the motor 17 is started, the output shaft of the motor 17 drives the worm 18 to rotate. The rotation of the worm 18 drives the worm gear 16, the rotating shaft 14, and the rotating plate 15 to rotate. The rotation of the rotating plate 15 can reasonably control the oil discharge flow rate, which facilitates the recovery and treatment of the oil.
[0018] Furthermore, the bottom of the fixed plate 6 and the top of the lower sealing cover 4 are both provided with movable grooves, and bearings are installed in the movable grooves, with the bearings sleeved on both ends of the rotating shaft 14.
[0019] Furthermore, a limiting plate 9 is fitted on the outer wall of the rotating shaft 14, and a locking block 8 is fixedly installed on the inner walls of both sides of the oil drain cylinder 1. The limiting plate 9 has a locking groove, and the locking block 8 is engaged and installed in the locking groove. The rotating plate 15 is in contact with the top of the limiting plate 9 and the bottom of the fixing plate 6.
[0020] Furthermore, a first buffer spring 12 is provided between the upper sealing cover 5 and the piston 10, and a second buffer spring 13 is provided between the fixing plate 6 and the piston 10 for resetting the fixing plate 6.
[0021] Furthermore, the fixing plate 6 has a connecting hole 7.
[0022] Working principle: When a large amount of oil is discharged rapidly, pressure is generated in the oil discharge pipeline. The pressure pushes the piston 10 upward. The upward movement of the piston 10 presses the damper 11, which buffers the piston 10 and reduces the pressure impact generated during oil discharge, protecting the oil discharge pipeline and surrounding components. By starting the motor 17, the output shaft of the motor 17 drives the worm gear 18 to rotate. The rotation of the worm gear 18 drives the worm wheel 16, the rotating shaft 14, and the rotating plate 15 to rotate. The rotation of the rotating plate 15 can reasonably control the oil discharge flow rate.
