Abstract
Description
Technical Field
[0001] This utility model relates to the field of stamping parts manufacturing technology, and in particular to a limiting and protective structure for producing bent stamping parts. Background Technology
[0002] Stamping is a forming process that uses a press and dies to apply external force to sheet metal, strip, tube, and profiles, causing them to undergo plastic deformation or separation, thereby obtaining workpieces (stampings) of the required shape and size. The products obtained by this process are stampings. The production of bent stampings is a process of bending blanks or semi-finished products of flat sheet metal or tube profiles into parts with a certain angle or shape using dies or other tools. This is one of the basic steps in the stamping process and is usually carried out on mechanical presses (punch presses), friction presses, or hydraulic presses. It can also be completed on special equipment such as plate bending machines, pipe bending machines, and stretch bending machines.
[0003] In the existing technology, when producing bent stamping parts, the stamping parts are usually placed directly on the surface of the lower die, and then the upper die is used to press down for stamping. When the stamping parts are placed on the surface of the lower die, the limiting function of the stamping parts is usually weak. During the pressing process of the upper die, the stamping parts are prone to displacement, which leads to a decrease in the processing accuracy of the stamping parts, an increase in the defect rate, and a decrease in production efficiency.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0034] As attached Figure 1-9 As shown, one embodiment of this utility model provides a limit protection structure for producing bent stamping parts, including a mounting box 1, and a protective component is provided inside the mounting box 1;
[0035] The protective component includes multiple columnar grooves 2, which are formed inside the mounting box 1 near the four corners. A buffer spring 3 is fixedly connected inside the columnar groove 2. A connecting rod 4 is fixedly connected to one end of the buffer spring 3. The connecting rod 4 is slidably connected inside the columnar groove 2. A connecting box 5 is fixedly connected to one end of the multiple connecting rods 4. A limit component is provided on the lower surface of the mounting box 1. The buffer spring 3 is used to press down on the connecting box 5. The buffer spring 3 is pressed by the connecting rod 4 through the connecting rod 4 to provide buffer protection.
[0036] As attached Figure 4 As shown, the limiting component includes a fixed shell 6, which is fixedly connected to the lower surface of the mounting box 1. The fixed shell 6 is rotatably connected to the inside of the bidirectional lead screw 7. One end of the bidirectional lead screw 7 is fixedly connected to a first knob 8. The external threads of the bidirectional lead screw 7 are connected to two connecting brackets 9. The two ends of the bidirectional lead screw 7 are set with threads in opposite directions. The middle of the connecting bracket 9 is provided with a threaded hole that matches the external thread of the bidirectional lead screw 7, so that the bidirectional lead screw 7 can easily drive the two connecting brackets 9 to move closer or further apart.
[0037] As attached Figure 5As shown, a limiting rod 10 is fixedly connected to one side of the connecting frame 9. Multiple grooves 11 are provided on one side of the limiting rod 10. A first spring 12 is fixedly connected inside the groove 11. A push block 13 is fixedly connected to one end of the first spring 12. A push plate 14 is fixedly connected to one side of the multiple push blocks 13. The push plate 14 is slidably connected inside the groove 11. The limiting rod 10 is used to limit the two sides of the stamping part. When the first spring 12 pushes the push block 13, the pushing force is transmitted to the push plate 14, which facilitates the buffering of the pressure of the limiting rod 10 contacted by the stamping part.
[0038] As attached Figure 4 As shown, the installation box 1 is equipped with a disassembly and assembly assembly, which includes two installation slots 15. The two installation slots 15 are opened on both sides of the inner wall of the installation box 1. A fixing rod 18 is fixedly connected to one side of the installation box 1. Two holes 19 are opened on one side of the fixing rod 18. The installation slots 15 are used for the installation of the lower mold 17, and the holes 19 facilitate the engagement of the insertion rod 23.
[0039] As attached Figure 6 As shown, an installation rod 16 is slidably connected inside the installation groove 15, and a lower mold 17 is fixedly connected between the two installation rods 16. The installation rods 16 facilitate limiting the lower mold 17 after it is installed inside the installation box 1.
[0040] As attached Figure 7 As shown, a movable block 20 is slidably connected to the outside of the fixed rod 18. A connecting shell 21 is fixedly connected to one side of the movable block 20. A limiting block 22 is slidably connected inside the connecting shell 21. An insert rod 23 is fixedly connected to the middle of the limiting block 22. A second spring 24 is fixedly connected to one side of the limiting block 22. A stud 25 is threadedly connected inside the movable block 20. A second knob 26 is fixedly connected to one end of the stud 25. A limiting plate 27 is fixedly connected to the other end of the stud 25. The limiting block 22 is used to prevent the insert rod 23 from moving out of the interior of the connecting shell 21. The second spring 24 pushes the insert rod 23 to engage with the slot 19 to make it secure. The stud 25 facilitates pushing the limiting plate 27 to fit tightly against one side of the lower mold 17, thus limiting the lower mold 17.
[0041] As attached Figure 8 As shown, a connecting groove 28 is provided on the lower surface of the connecting box 5, and a sliding groove 29 is provided on one side of the inner wall of the connecting box 5. A slider 30 is slidably connected inside the sliding groove 29, and an insert 33 is fixedly connected to the upper surface of the slider 30. A screw 32 is rotatably connected to one side of the connecting box 5, and a knob 31 is fixedly connected to one end of the screw 32. The insert 33 is threaded to the outside of the screw 32, and the inside of the insert 33 is provided with a threaded groove that matches the texture of the screw 32. When the slider 30 slides inside the sliding groove 29, it is convenient to limit the insertion 33 when it is pushed by the screw 32.
[0042] As attached Figure 9 As shown, a fixing block 34 is provided inside the connecting groove 28. An upper mold 35 is fixedly connected to the lower surface of the fixing block 34. A limiting groove 36 is provided inside the fixing block 34. The fixing block 34 facilitates the installation of the upper mold 35, and the limiting groove 36 facilitates the connection and engagement of the insert block 33.
[0043] Working principle: In use, the upper mold 35 and the lower mold 17 are first installed inside the mounting box 1 and the connecting box 5 respectively using the disassembly and assembly components. The connecting box 5 is then installed at the output end of the downward driving force. The stamping part is then placed on the upper surface of the lower mold 17. The first knob 8 is turned. When the first knob 8 drives the bidirectional lead screw 7 to rotate, the threads on both sides of the bidirectional lead screw 7, which are set in opposite directions at both ends, drive the connecting brackets 9 on both sides to move closer to each other. At this time, the connecting brackets 9 slide inside the fixed shell 6. During the process of the connecting brackets 9 on both sides moving closer to each other, the limiting rods 10 on both sides move closer to the sides of the stamping part. When they are in close contact with the stamping part, the stamping part is limited. At the same time, under the action of the first spring 12 pushing the push block 13 and the push plate 14, the tightness of the stamping part is improved when it is limited, and it is convenient to buffer and protect the pressure applied by the limiting rod 10 to one side of the stamping part.
[0044] When the driving force drives the connecting box 5 to press down, and the connecting box 5 drives the upper mold 35 to press down, the connecting box 5 simultaneously drives multiple connecting rods 4 to slide inside the columnar groove 2, so that the connecting rods 4 push and squeeze the buffer spring 3, thereby buffering the pressure brought by the connecting box 5 and the upper mold 35 on the stamping part and the lower mold 17 under the elastic force of the buffer spring 3.
[0045] When disassembling the lower mold 17, first turn the second knob 26. When the second knob 26 drives the stud 25 to rotate, it drives the limiting plate 27 to rotate, causing the limiting plate 27 to separate from one side of the lower mold 17. Then pull the insertion rod 23. One end of the insertion rod 23 disengages from the corresponding hole groove 19, releasing the limiting of the moving block 20. Then slide the moving block 20 so that the moving block 20 slides outside the fixed rod 18. After the moving block 20 is moved to one end of the fixed rod 18, the lower mold 17 is pulled out from the inside of the mounting box 1 by the action of the mounting rod 16 sliding inside the mounting groove 15, which facilitates the disassembly of the lower mold 17. The operation is reversed during installation.
[0046] When disassembling the upper mold 35, turn the knob 31. The knob 31 drives the screw 32 to rotate, causing the screw 32 to rotate inside the fixing block 34. Under the action of the slider 30 sliding inside the slide groove 29 and under the action of the threaded groove inside the insert block 33, the insert block 33 is moved, causing the insert block 33 to disengage from the inside of the limiting groove 36, releasing the limiting of the fixing block 34. Then, the fixing block 34 is pulled out from the inside of the connecting groove 28, thereby disassembling the upper mold 35. The above operation is reversed during installation.
[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
