Description

Technical Field

[0001] The utility model relates to the technical field of punching machines, in particular to a punching machine protection device with real-time alarm push function. Background Art

[0002] The stamping machine deforms and forms the metal material by placing the metal sheet in a die and then applying pressure between the upper and lower halves of the die. This process is usually driven by a hydraulic system to move the slide up and down to achieve the stamping of the metal sheet.

[0003] At present, in the prior art, a Chinese patent with announcement number CN218555389U discloses a safety protection mechanism for a stamping machine. The device drives the incomplete gear to rotate by driving the servo motor, which can drive the stamping seat to move back and forth. It can prevent the stamping operator's hands from being directly under the punching head during the process of taking out the stamped parts after stamping and placing the stamping plates to be stamped. However, in actual use, since the hydraulic press is the core driving part of the stamping machine, its rapid activity has brought about an improvement in production efficiency, but it may also cause delays in the protective device in an emergency, thereby increasing the risk of accidents. In order to overcome this challenge, the design and implementation of the hydraulic press's active linkage warning push device can significantly improve the safety performance of the stamping machine. In view of this, we propose a stamping machine protection device with real-time alarm push. Utility Model Content

[0006] Arc grooves, the surface of the punching seat is provided with arc grooves, and the arc grooves are provided in two groups;

[0007] An annular sleeve is fixedly connected to the outer wall of the connecting column of the punching head.

[0008] Preferably, the surface of the annular sleeve is fixedly connected to the connecting plate, and the connecting plate is fixedly connected with a rack. When the movable column of the hydraulic cylinder drives the punching head to apply pressure downward to realize the deformation operation of the metal material, the annular sleeve on the movable column will then operate downward synchronously.

[0009] Preferably, a movable cavity is opened on the inner wall of the punching seat, a gear is rotatably connected in the movable cavity, the gear is meshingly connected with a rack, and the rack slides against the outer wall of the punching machine body to prevent interference with other punching components during movement.

[0010] Preferably, a rotating groove is provided inside the punching seat, the rotating groove is communicated with the movable cavity, a rotating column is rotatably connected in the rotating groove, and the rotating column is fixedly connected to a gear, and the gear and its rotating column are driven to rotate through the downward movement of the rack.

[0011] Preferably, one end of the rotating column away from the gear is fixedly connected to a positioning rod, and a movable rod is sleeved in the positioning rod, and the rotation of the rotating column drives the eccentric rotation of the positioning rod.

[0012] Preferably, the movable rod is slidably connected in the arc groove, and the movable rod is slidably connected in the sliding groove opened in the baffle.

[0013] The utility model provides a punching machine protection device with real-time alarm push. It has the following beneficial effects:

[0014] (1) The real-time alarm push-pushing protection device of the stamping machine is equipped with an alarm push device. When the movable column of the hydraulic cylinder drives the stamping head to apply pressure downward, the annular sleeve will move downward synchronously. The connecting plate connected to the annular sleeve drives the rack to slide against the outer wall of the stamping machine body. The downward movement of the rack drives the gear and its rotating column to rotate. The eccentric rotation of the positioning rod on the rotating column causes the movable rod to move up and down accordingly. When the stamping head is in the process of pressing the die downward, the baffle is lifted to promptly warn the staff to stop the operation steps, thereby preventing the material from splashing and causing potential safety hazards to the staff.

[0015] (2) The real-time alarm push-pushing press protection device is equipped with a baffle. When the press starts working, the baffle will move accordingly, and directly convey the working status of the press to the operator through its movement state. Secondly, during the stamping process, the metal sheet may produce fragments or splashes due to the strong impact force. The baffle can effectively block these splashes and confine them to the working area of ​​the press, thereby protecting the safety of the operator. BRIEF DESCRIPTION OF THE DRAWINGS
