Description

Technical Field

[0001] The utility model relates to the technical field of buffering of stamping equipment, in particular to a buffering mechanism of stamping equipment. Background Art

[0002] Stamping equipment is a kind of pressure processing equipment that applies external force to plates, strips, pipes and profiles through dies to make them plastically deform or separate, so as to obtain workpieces of required shapes and sizes. During the stamping process, the high-speed contact between the punch and the workpiece will generate huge impact force. The buffer device can absorb and slow down this impact force, thereby reducing the vibration of the equipment itself and the surrounding environment, reducing noise, improving the comfort of the working environment, and also reducing the impact on the equipment foundation and peripheral equipment.

[0003] Publication No. CN211304459U discloses a buffer-type stamping die, which uses a buffer spring and a buffer block, and the elastic part is an arched structure that gradually arches downward from top to bottom, thereby further increasing the buffering performance.

[0004] However, the above application still has the following problems: in high-intensity, high-frequency and large-impact force variation stamping operations, the elastic buffering of the buffer spring and the buffer block, combined with the elastic part of the arch structure, this single elastic buffer often appears to be inadequate, especially when dealing with stamping operations with large instantaneous impact force. This single elastic buffer cannot effectively reduce the impact force to an ideal level. Utility Model Content

[0019] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar symbols throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0020] like Figure 1-Figure 3 The buffer mechanism of a stamping equipment shown in the figure includes a plurality of outer cylinders 1, an inner cylinder 2 is installed in the outer cylinder 1, the outer cylinder 1 and the inner cylinder 2 are connected to each other, buffer is contained in both the outer cylinder 1 and the inner cylinder 2, a buffer member 3 is installed in the inner cylinder 2, a rotating member 4 is provided in the inner cylinder 2, and a driving member 5 is provided on the outer cylinder 1, the driving member 5 is used to drive the rotating member 4 to rotate, and the driving member 5 is connected to the buffer member 3.

[0021] Several outer cylinders 1 can be installed on a fixed platform of the stamping equipment, or can be directly installed and placed under the stamping moving end of the stamping equipment, and the stamping moving end of the stamping equipment contacts the driving member 5 to drive the driving member 5 to move downward.

[0022] As needed, a connecting plate can be installed on the stamping mobile end of the stamping equipment to ensure that the stamping mobile end can contact the driving member 5 when pressing down. If the stamping mobile end of the stamping equipment itself can contact the driving member 5, the connecting plate may not be installed.

[0023] A further improvement of the technical solution is that a plurality of first through holes 6 are provided on the inner cylinder 2, and a plurality of second through holes 7 are provided on the inner cylinder 2, the number of the first through holes 6 is greater than the number of the second through holes 7, the first through holes 6 are located above the second through holes 7, and in the normal state of the piston 32, when not pressed downward, the first through holes 6 are located above the piston 32, and the second through holes 7 are located below the piston 32.

[0024] The number of the first through holes 6 is greater than the number of the second through holes 7. The purpose is that when the piston 32 is pressed down, the buffer solution below the piston 32 can quickly flow back into the top of the piston 32 to avoid the buffer solution overflowing the outer tube 1 due to the piston 32 descending too quickly.

[0025] A further improvement of the technical solution is that the buffer member 3 includes a spring 31, and one end of the spring 31 is installed in the inner tube 2, one end of the spring 31 is installed at the bottom of the inner surface of the inner tube 2, and the other end of the spring 31 is installed with a piston 32, and the piston 32 slides in the inner tube 2.

[0026] The driving member 5 moves downward under the impact of external force, which is specifically manifested as the threaded rod 51 moving downward, and the threaded rod 51 moving downward drives the piston 32 to squeeze the buffer in the inner tube 2. At this time, the buffer is discharged from the second through hole 7 of the inner tube 2 under pressure, enters the chamber between the inner tube 2 and the outer tube 1, and flows back to the chamber above the piston 32 through the first through hole 6. In this process, the spring 31 is compressed to achieve the first buffering effect.

[0027] When the external force disappears, the elastic restoring force of the spring 31 bounces the piston 32 back to the initial position, waiting for the next punching action. In this process, the flow of the hydraulic oil generates resistance, achieving a second buffering effect.

[0028] A further improvement of the technical solution is that the rotating member 4 includes a bearing 41, which is installed in the inner tube 2 through a support frame, and a rotating ring 42 is rotatably connected to the bearing 41, a plurality of fan blades 43 are installed on the outer periphery of the rotating ring 42, and an internal thread is opened in the rotating ring 42.

[0029] Since the threaded rod 51 is threadedly connected with the rotating ring 42, the downward movement of the threaded rod 51 will drive the rotating ring 42 and the fan blades 43 to rotate. The fan blades 43 rotate in the buffer to generate resistance, thereby achieving a third buffering effect.

[0030] A further improvement of the technical solution is that the driving member 5 includes a threaded rod 51, and one end of the threaded rod 51 passes through the outer cylinder 1, the inner cylinder 2, the bearing 41 and the rotating ring 42 in sequence and extends into the inner cylinder 2, one end of the threaded rod 51 is installed on the piston 32, and the other end of the threaded rod 51 is installed with a pressure plate 52, the threaded rod 51 and the outer cylinder 1 are connected at a sliding connection, the threaded rod 51 and the inner cylinder 2 are connected at a sliding connection, the threaded rod 51 and the bearing 41 are connected at a sliding connection, and the threaded rod 51 and the rotating ring 42 are connected at a threaded connection.

[0031] A further improvement of the technical solution is that the buffer is hydraulic oil.

[0032] When the driving member 5 is impacted by external force, the threaded rod 51 moves downward, which will drive the piston 32 to squeeze the buffer solution in the inner cylinder 2. After the buffer solution is pressurized, it is discharged from the second through hole 7 of the inner cylinder 2, and at the same time flows back to the chamber formed between the piston 32 and the inner cylinder 2 through the chamber between the inner cylinder 2 and the outer cylinder 1 and the first through hole 6. At the same time, the spring 31 is compressed, thereby achieving a primary buffering effect; when the external force disappears, the spring 31 rebounds the piston 32 to the starting point, waiting for the next action. In this process, the flow of hydraulic oil will generate resistance, thereby achieving a secondary buffering effect; and the threaded rod 51 and the rotating ring 42 are threadedly connected at the penetration point, so that the threaded rod 51 will also drive the rotating ring 42 and the fan blades 43 to rotate during the downward movement. The fan blades 43 rotate in the buffer solution and generate resistance, thereby achieving a triple buffering effect, so that when facing a stamping operation with a large instantaneous impact force, it has a good buffering effect.
