Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, and more specifically to a quick-release mechanism of a stamping die. Background Art

[0002] Stamping is a forming method that uses a press and a die to apply external force to plates, strips, tubes and profiles to cause them to undergo plastic deformation or separation, thereby obtaining a workpiece (stamping part) of the desired shape and size.

[0003] When the existing stamping die is in use, pressure is usually applied to the punch, so that the punch applies external force to the workpiece to be processed to cause it to deform. Under long-term stamping use, friction is formed between the surface of the punch and the workpiece through the action of force, which can easily cause the surface of the punch to wear and thus reduce the stamping accuracy. The staff is required to replace the punch regularly. The existing process of disassembling the punch is relatively cumbersome, time-consuming and labor-intensive. Therefore, how to provide a quick-release structure of a stamping die that can quickly disassemble and install the punch is particularly important. In view of this, we propose a quick-release mechanism for a stamping die. Utility Model Content

[0025] The quick-release assembly 5 includes a fixed box 501 fixedly connected to the lower section of the guide plate 4, a slide groove A502 and a slide groove B503 are provided in the fixed box 501, a limit column 504 is slidably connected in the slide groove A502, a connecting rod 505 is fixedly connected to the surface of the limit column 504, and a triangular inclined block 506 is fixedly connected to the lower end surface of the limit column 504 on both sides symmetrically through the cross plate, and through the triangular inclined block 506, when the triangular inclined block 506 slides downward, it can contact the inclined surface of the limit block 7 and limit its position, and the movement of its inclined surface can drive the limit block 7 to move. It extends outward so that the fixing seat 12 can be clamped and fixed, which can shorten the time for installation and removal of the punch, reduce the difficulty of operation for the staff, and avoid personal injury and damage to the punch due to incorrect operation. A through hole 6 is provided on the lower end face of the slide groove B503, and the limiting blocks 7 are symmetrically slidably connected on both sides of the through hole 6. The opposite sides of the two limiting blocks 7 are provided with inclined surfaces, and the inclined surfaces of the limiting blocks 7 are in contact with the triangular inclined blocks 506. A spring A9 is fixedly connected to the side wall of the slide groove A502, and the surface of the limiting column 504 is also sleeved in the spring A9.

[0026] In the embodiment of the utility model, a limiting assembly 8 is arranged on the surface of the connecting rod 505 through the side wall of the fixed box 501, and the limiting assembly 8 includes a moving frame 801 slidably connected to the end of the connecting rod 505, an extension plate 802 is fixedly connected to one side of the moving frame 801, and the extension plate 802 includes a serrated portion A8021, and a fixing frame 803 is fixedly connected to one side of the fixed box 501, and the fixing frame 803 includes a serrated portion B8031 and a protruding portion 8032, and the serrated portion B8031 is meshed with the serrated portion A8021, and the serrated portion B8031 is meshed with the serrated portion A8021. A placement cavity is formed between 31 and the protrusion 8032. By setting the placement cavity, the position where the limit column 504 needs to be fixed when moving up and down can be limited, thereby improving the accuracy of the position where the limit column 504 needs to be fixed. By setting the serrated portion A8021 and the serrated portion B8031, the meshing between the two can be utilized, and the serrated surface can be utilized to improve the tightness and friction between the two, so that they can bite each other, thereby fixing the limit column 504 when it moves to the corresponding position, thereby improving the stability of the position of the limit column 504 after being fixed.

[0027] In an embodiment of the utility model, an arc-shaped groove is provided on the lower end surface of the through hole 6, and springs B10 are fixedly connected to the symmetrical two sides of the arc-shaped groove respectively. By setting the spring B10, the elasticity and reset function of the spring B10 can be utilized to limit the limit block 7 in the through hole 6 when it moves, thereby improving the stability of the movement of the limit block 7. The opposite sides of the two springs B10 are fixedly connected to the movable plates 11 respectively, and the upper end surface of the movable plate 11 is fixedly connected to the lower end surface of the limit block 7.

[0028] As another embodiment of the utility model, a fixing seat 12 is simultaneously clamped on the surface of the limiting block 7 , and a punch is arranged on the lower end surface of the fixing seat 12 .

[0029] Working principle: This embodiment provides a quick-release mechanism for a stamping die. When the punch needs to be installed, the fixing seat 12 is first sleeved on the surface of the fixing box 501, and then the connecting rod 505 and the moving frame 801 are pressed downward at the same time, so that the extension plate 802 overlaps the protruding portion 8032, driving the serrated portion A8021 and the serrated portion B8031 to separate. At this time, the moving frame 801 is slid to separate its surface from the placement cavity, and then the connecting rod 505 and the moving frame 801 are moved downward, and at the same time, the limiting column 504 is driven to move downward, and the spring A9 is squeezed, so that the triangular inclined block 506 can abut against the surface of the limiting block 7 downward, and the two limiting blocks 7 are driven to continue to extend toward the surface of the fixed box 501 through the inclined surface. When the limiting block 7 is extended, the spring B 10 is stretched and clamped in the fixed seat 12 to fix its position. At this time, the sliding movable frame 801 makes its surface slide into the placement cavity, and uses the reset function of the spring A9 to drive the movable frame 801 to be slightly lifted in the placement cavity, so that the sawtooth portion A8021 and the sawtooth portion B8031 are engaged, so as to fix the position of the limit block 7. When the punch needs to be disassembled, it is only necessary to disengage the movable frame 801 from the placement cavity, and through the reset effect of the spring A9, drive the limit column 504 and the triangular bevel block 506 to be lifted upward, thereby canceling the limit on the limit block 7, allowing the spring B10 to be reset, and at the same time drive the limit block 7 to retract into the through hole 6, thereby canceling the limit on the fixed seat 12, so that the punch can be taken.
