Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a precision bending mold with a simple stripping mechanism. Background Art

[0002] Precision bending dies are used for precisely bending sheet metal. Pressure is applied by upper and lower dies to plastically deform the sheet, creating the desired bent shape. Because the bending process requires high precision, the design, material, and structure of the dies must be strictly controlled to ensure the consistency and quality of the finished product. A simple stripper mechanism, an auxiliary device within the die, quickly removes the finished workpiece from the die, preventing friction or jamming between the workpiece and the die. This improves production efficiency, protects both the workpiece and the die, and ensures workpiece quality while simplifying operation and maintenance.

[0003] In most cases, the existing bending mold uses an upper mold to drive the punch head to press the workpiece downward for stamping to achieve the bending effect. However, when used on some more precise products, the product will be stuck in the lower mold in most cases, which makes it inconvenient to remove. The staff often needs to use tools to remove the product. The above operation is not only time-consuming and labor-intensive, but also reduces the practicality of the bending mold. Therefore, a precision bending mold with a simple stripping mechanism is proposed to solve the above problem. Utility Model Content

[0025] Specifically, when processing a workpiece, it is first necessary to firmly place the workpiece to be processed above the jacking plate 7; at this time, the mounting seat 3 is firmly connected to the driving mechanism; next, by starting the driving mechanism, the driving mechanism will start to operate, driving the mounting seat 3 to move downward, and the mounting seat 3 will then drive the mold 2 5 to perform a downward pressing operation to accurately stamp the workpiece; in this process, the mold 2 5 pushes the punch head 19, forcing the workpiece to slide within the inner wall of the limiting hole 6 with the assistance of the jacking plate 7; at the same time, the jacking plate 7 is squeezed and comes into contact with the trapezoidal block 12 located below it, pushing the trapezoidal block 12 to move along the inner wall of the guide groove 9; at this time, the trapezoidal block 1 2 drives the slot plate 13 to engage tightly with the outer wall of the spring ball 15, achieving a precise bending effect on the workpiece; when it is necessary to remove the material, by pressing the handle 1602, the spring 2 1603 is driven to contract, and then the guide rod 1604 is pushed to retract the spring ball 15 into the interior of the fixed block 14, causing the slot plate 13 to separate from the outer wall of the spring ball 15, and the pressure of the spring 1003 disappears at this time; then, the spring 1003 will rebound quickly, pushing the connecting plate 11 to return to its original position, thereby driving the lifting plate 7 to quickly reset; during the resetting process of the lifting plate 7, the workpiece is quickly ejected, completing the entire processing process; this series of actions ensures that the bending and stripping process of the workpiece is accurate and efficient.

[0026] Reference Figure 1 、 Figure 4 and Figure 5 , the mounting seat 3 is internally threaded with a bolt 17, the bolt 17 is threadedly connected to the inside of the mold 2 5, and the lower surface of the mold 2 5 is fixedly connected to a punch head 19; the lower surface of the mold 2 5 is fixedly connected to a limiting column 18, and a limiting hole 20 is provided inside the mold 1 4, and the limiting column 18 is slidably connected to the inner wall of the limiting hole 20; the top of the inner wall of the mold 2 5 is fixedly connected to a hinge seat 21, and the hinge seat 21 is internally rotatably connected to a left-right symmetrical connecting rod 22, and a slide groove 25 is provided inside the connecting rod 22; one side of the outer wall of the connecting rod 22 is fixedly connected to a fixed plate 23, and the fixed plate 23 is rotatably connected to a roller 24; one side of the inner wall of the mold 2 5 is rotatably connected to a damper 26, and the outer wall of the damper 26 is provided with a spring three 27, and the output end of the spring three 27 is provided with a slider 28, which is slidably connected to the inner wall of the slide groove 25;

[0027] Specifically, when the mold 2 5 is pressed downward, it will simultaneously drive the roller 24 to roll smoothly above the mold 1 4; this process not only causes the roller 24 to move, but also pushes the limit column 18 to quickly insert into the limit hole 20, accurately achieving the positioning effect of the mold; as the roller 24 rolls, the fixed plate 23 is also driven, pushing the connecting rod 22 to rotate accurately inside the hinge seat 21, ensuring smooth and continuous movement; at the same time, the movement of the connecting rod 22 drives the slider 28 to slide in a controlled manner within the inner wall of the slide groove 25, ensuring the stability of the slider 28 throughout the process; the sliding of the slider 28 further causes the damper 26 and the spring three 27 to be squeezed, producing an effective buffering effect; through the precise cooperation of the damper 26 and the spring three 27, the impact force of the mold 2 5 during the downward pressing process is effectively reduced, preventing the product from bursting during high-intensity stamping; this series of coordinated actions not only ensures the accuracy of the processing process, but also effectively protects the integrity of the workpiece, thereby improving production safety and product quality.

[0028] Working principle: When in use, first place the workpiece to be processed above the jacking plate 7, then connect the mounting seat 3 to the driving mechanism, and then start the driving mechanism. At this time, the mounting seat 3 is pressed down by the driving mechanism, and the mounting seat 3 will drive the mold 2 5 to press down the stamping product. At this time, the mold 2 5 drives the punching head 19 to push the product so that the jacking plate 7 slides within the inner wall of the limiting hole 6. At this time, the jacking plate 7 will resist the trapezoidal block 12 and push the trapezoidal block 12 to move. At this time, the movement of the trapezoidal block 12 causes the slot plate 13 to engage with the outer wall of the spring ball 15. At this time, the lifting plate 7 will contact the outer wall of the resistance block 8, thereby achieving the effect of bending the product. When the material needs to be removed, the handle 1602 is pressed. At this time, the handle 1602 drives the spring 2 1603 to contract, which drives the guide rod 1604 to push the spring ball 15 into the fixed block 14. At this time, the slot plate 13 is separated from the outer wall of the spring ball 15, thereby causing the spring 1 1003 to lose pressure. At this time, the spring 1 1003 quickly pushes the connecting plate 11 to move, thereby pushing the lifting plate 7 to quickly reset. At this time, the lifting plate 7 is reset to achieve the effect of quickly ejecting the product;

[0029] Secondly, when mold 2 5 is pressed down, it will drive roller 24 to roll above mold 1 4, and at the same time drive limit column 18 to quickly insert into limit hole 20 to achieve positioning effect. At this time, the movement of roller 24 can realize the effect of making fixed plate 23 push connecting rod 22 to rotate inside hinge seat 21. At the same time, the movement of connecting rod 22 can realize the effect of pushing slider 28 to slide on the inner wall of slide groove 25. At this time, the movement of slider 28 can realize the effect of squeezing damper 26 and spring three 27. At this time, the cooperation of damper 26 and spring three 27 can realize the effect of slowing down the impact force of pressing down mold 2 5 to prevent the product from bursting.

[0030] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
