Description

Technical Field

[0001] This utility model relates to the field of stamping die adjustment structure technology, and in particular to an automatic die adjustment structure. Background Technology

[0002] Steel plate punching is a typical processing method in metal stamping. It is mainly used to separate steel plates through the pressure of dies and punch presses to obtain parts of the required shape and size, or to punch holes of various shapes in steel plates. When punching mounting holes in steel plates, the punching positions are generally symmetrically distributed along the axis of symmetry of the wide side of the steel plate. Different specifications of steel plates often require different punching positions or die spacings. Existing die adjustment structures mostly rely on manual adjustment, which requires repeated calibration. Furthermore, manual measurement of die spacing is prone to errors, leading to deviations in the punching hole position. Typically, one machine only processes steel plates of one specification. If other specifications of steel plates are changed, the die position needs to be readjusted and calibrated manually. This results in low production efficiency and makes it difficult to meet the needs of multi-variety, small-batch production. Utility Model Content

[0024] Reference Figure 1-5 As shown, an automatic mold adjustment structure includes: The system comprises two fixed plates 2, a sliding assembly 1, and a punching assembly 3. The sliding assembly 1 controls the two fixed plates 2 to move closer or further apart. A through-plate notch 22 is formed on the side of the two fixed plates 2 facing each other. The punching assembly 3 is mounted on the fixed plates 2, with its punching end extending from the upper or lower side of the through-plate notch 22 to punch holes. The system also includes a controller, whose output is electrically connected to the input of the sliding assembly 1 and the input of the punching assembly 3. The controller automatically controls the drive component 12 to drive the fixed plates 2 to move relative to each other, thereby precisely and quickly adjusting the distance between the through-plate notches 22 on both sides. This eliminates the need for manual measurement and adjustment, effectively avoiding human error and ensuring the symmetry and processing accuracy of the punched holes.

[0025] Furthermore, the sliding assembly 1 includes a frame 11, two drive members 12, and a slide rail 13. The frame 11 includes a base 111 and a side plate 112. The side plate 112 is connected to one side of the base 111. The fixed plate 2 is located above the base 111 and on one side of the side plate 112. The side of the fixed plate 2 facing the side plate 112 has a sliding groove 23. The sliding groove 23 is embedded in the slide rail 13 and slidably connected. The two drive members 12 are used to drive the two fixed plates to move back and forth along the slide rail 13. The driving component 12 includes a lead screw 121, a lead screw flange 122, and a motor 123. The lead screw 121 is disposed between the base 111 and the lower surface of the fixed plate 2, and bearing seats are provided at both ends of the lead screw 121, which are fixed to the frame 11. The lead screw flange 122 is fixedly connected to the lower surface of the fixed plate 2, and the lead screw 121 passes through the lead screw flange 122. The lead screw flange 122 and the lead screw 121 are threaded together, allowing the lead screw flange 122 to move linearly on the lead screw 121. The upper end of the lead screw flange 122 is fixedly connected to the lower end of the fixed plate 2. The motor 123 drives the lead screw 121 to rotate. The lead screw 121 is connected to the output shaft of the motor 123 through a coupling. The motor 123 is fixedly mounted on the frame 11 and is electrically connected to the controller. The motor 123 receives signals from the controller to drive the lead screw 121 to rotate forward or backward, control the movement of the lead screw flange 122, and thus drive the fixed plate 2 to control the distance between the two fixed plates 2.

[0026] Furthermore, a slider is connected to the side of the fixed plate 2 facing the side plate 112, and a groove 23 is provided on the side of the slider facing the side plate 112, thereby forming two fixed plates 2 that can move relative to each other. A punching assembly 3 is provided on the side of the fixed plate 2 away from the driving component 12. The punching assembly 3 includes a mounting base 31, a telescopic component 32, a triangular connecting plate 33, and a punch 34. The mounting base 31 is provided on the upper surface of the fixed plate 2. The telescopic component 32 is rotatably connected to the mounting base 31 by a pin. The telescopic component 32 can be a cylinder or a hydraulic cylinder and is electrically connected to the controller. In this embodiment, the telescopic component 32 is a hydraulic cylinder. The hydraulic cylinder is provided with an oil inlet and an oil outlet. The triangular connecting plate 33 is connected to the other end of the telescopic component 32 away from the mounting base 31 by a pin. The punch 34 is rotatably connected to the end of the triangular connecting plate 33 near the through plate notch 22. The end of the triangular connecting plate 33 near the fixed plate 2 is rotatably connected to the fixed plate 2 by a pin. The punch 34 passes through the guide hole on the fixed plate 2, so that the punch 34 can slide and move in the vertical direction. In this embodiment, the through plate notch 22 is a concave mold, which is fixed to the through groove 21 by bolt connection or snap connection.

[0027] The punch 34 includes a 341 and a punch 342. The connector 341 is rotatably mounted on the triangular connecting plate 33. The punch 342 is sleeved on the connector 341, and a movable gap 343 is formed between the shaft of the punch 342 and the open end of the connector 341. Because there is motion interference between the triangular connecting plate 33 and the punch 34 during the pressing process, the smoothness of the movement of the punch 342 is affected. Therefore, the problem of motion interference is solved by setting the movable gap 343, thereby improving the smoothness of the stamping process. The punch 342 is slidably mounted on the fixed plate 2 and located above the through plate notch 22. When hydraulic oil enters the hydraulic cylinder through the inlet, it pushes the piston rod to extend, causing the triangular connecting plate 33 to rotate. Under the influence of the triangular connecting plate 33, the punch 34 is pressed down until the punch 342 contacts the through hole notch 22. After the stamping is completed, the hydraulic oil is discharged from the hydraulic cylinder through the outlet, causing the piston rod to retract, pushing the triangular connecting plate 33 to rotate. Under the influence of the triangular connecting plate 33, the punch 342 rises until the punch 34 returns to its original position.

[0028] Furthermore, each fixed plate 2 has a through groove 21 parallel to the slide rail 13 at the corresponding through-plate notch 22. The through groove 21 is an elongated groove that runs through the fixed plate 2. A mold is provided at the output end of the corresponding punching assembly 3, i.e., below the punch 34. The mold has the through-plate notch 22 and can be detachably fixed in the through groove 21 by bolt connection or snap-fit ​​connection. The through grooves 21 on the two fixed plates 2 are arranged opposite to each other and enclose a stamping space for placing the steel plate to be processed.

[0029] Furthermore, the equipment is equipped with a controller, which can be a PLC or a microprocessor. The controller's output is electrically connected to the input of the sliding assembly 1 and the input of the punching assembly 3. The controller can generate adjustment commands to control the movement position of the fixed plate 2 based on externally input steel plate specifications and die spacing parameters. A displacement sensor is installed on the frame 11 near the drive component 12, with the detection end of the displacement sensor facing the lead screw flange 122. The displacement sensor is electrically connected to the controller and is used to detect the displacement of the fixed plate 2 in real time and feed the signal back to the controller to achieve closed-loop control and ensure precise adjustment of the die spacing. A photoelectric sensor is installed on the fixed plate 2 near the punch component 34. The photoelectric sensor is electrically connected to the controller. The photoelectric sensors on the two fixed plates 2 are arranged opposite each other to control the minimum distance between the two fixed plates 2, prevent the two fixed plates 2 from colliding, and improve the safety of the stamping process.

[0030] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
