Abstract
Description
Technical Field
[0001] This utility model relates to the field of stamping forming technology, specifically to a fixed frame stamping forming device. Background Technology

[0003] During the stamping process, the fixed frame needs to be stamped and bent. The current stamping method requires placing the material to be stamped on the worktable and then using the longitudinal movement of the stamping structure to stamp the material. However, when stamping the material for bending, the stamping head is generally designed as an integral piece. When different bending requirements are needed, the stamping head needs to be disassembled and replaced, which makes the stamping shape that the stamping head can be stamped relatively limited.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0027] Example
[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, an embodiment of the present invention provides a fixed frame stamping forming device, including a base 1, a bracket 2 fixed at one top end of the base 1, a hydraulic cylinder 3 fixed at one top end of the bracket 2, a lower pressure seat 4 connected to the output end of the hydraulic cylinder 3, and a locking hole 5 opened on the front surface of the lower pressure seat 4. The locking holes 5 are distributed in a circular array along the center point of the front end of the lower pressure seat 4, and the inner diameter of the locking holes 5 is adapted to the outer diameter of the locking rod 14.
[0029] A rotating wheel 6 is rotatably connected to the center of the front end of the lower pressure seat 4, and a driving gear 7 is fixedly connected to one end of the rotating wheel 6. Multiple teeth are evenly distributed on the outer ring surfaces of both the driving gear 7 and the driven gear 8 along their center points. The driven gear 8 is meshed with one side of the bottom of the driving gear 7, and a double-ended screw 9 is fixedly connected to the center point of one end of the driven gear 8. The double-ended screw 9 is symmetrically distributed along the vertical center line of the lower pressure seat 4, and external threads are symmetrically opened on the outer ring surfaces of the double-ended screw 9 on both sides. The two-way screw 9 is arranged in opposite directions. One end of the outer ring surface of the two-way screw 9 is fitted with a threaded sleeve 10, and the side wall of the two-way screw 9 is rotatably connected to a push rod 11. The two ends of the push rod 11 are rotatably connected to the threaded sleeve 10 and the bending plate 12 respectively through connecting ears. The other end of the push rod 11 is connected to the bending plate 12, and a guide rod 13 is fixed at the top end of the bending plate 12. The guide rod 13 is symmetrically distributed along the vertical center line of the bending plate 12, and the size of the guide rod 13 is adapted to the size of the hole opened in the side wall of the lower pressure seat 4.
[0030] In use, the hydraulic cylinder 3 longitudinally pushes the lower pressure seat 4 fixedly connected to its bottom, facilitating the subsequent movement of the lower pressure seat 4 to drive the movement of the bending plates 12 on both sides, thereby performing bending and stamping processing on the workpiece in conjunction with the bending plates 12. When it is necessary to adjust the distance between the two bending plates 12, the rotating wheel 6 is turned. At this time, the rotating wheel 6 rotates, causing the driving gear 7 fixedly connected to one end to rotate. Then, the rotation of the driving gear 7 drives the driven gears 8 meshing on both sides at its bottom to rotate as well. Thus, the rotation of the two driven gears 8 achieves the synchronous rotation of the two bidirectional screws 9. Since the two driven gears 8 move in opposite directions, the bidirectional screws 9 symmetrically arranged on both sides also rotate in opposite directions. Because the bidirectional screws 9 and the threaded sleeve 10 are connected by threaded grooves... The threaded connection allows the rotation of the bidirectional screw 9 to facilitate the movement of the threaded sleeve 10. The threaded sleeve 10, moving along the bidirectional screw 9, pushes the push rod 11, which is rotatably connected to one side via a connecting lug. The push rod 11 then pushes the bending plate 12, which is rotatably connected to the other end via a connecting lug. It is noteworthy that since both ends of the bidirectional screw 9 are symmetrically arranged with external threads, the threaded sleeves 10 on the outer annular surfaces of both ends move in opposite directions as the bidirectional screw 9 rotates. This causes the push rods 11 on both sides to push the bending plate 12. The operation of the structures on both sides of the lower pressure seat 4 facilitates the subsequent movement of the bending plates 12 in opposite directions, allowing for adjustment of their spacing and facilitating better bending of the workpiece.
[0031] like Figure 4 As shown, in some embodiments, a locking rod 14 passes through the inner side of the rotating wheel 6, and an auxiliary sliding plate 15 is sleeved on the outer ring surface of one end of the locking rod 14. A return spring 16 is fixedly connected to one end surface of the auxiliary sliding plate 15, and the two ends of the return spring 16 are respectively fixedly connected to the outer periphery of one end of the auxiliary sliding plate 15 and the inner side wall of the rotating wheel 6.
[0032] In use, when it is necessary to rotate the wheel 6, pull the locking rod 14. At this time, the locking rod 14 is pulled and drives the auxiliary slide plate 15 to slide inside the wheel 6. Then, one end of the locking rod 14 disengages from the inside of the lock hole 5, which facilitates the subsequent rotation of the wheel 6. As the locking rod 14 moves, the auxiliary slide plate 15 will drive the return spring 16 to deform and generate a reverse force, which facilitates the subsequent use of the reverse force generated by the deformation of the return spring 16 to assist the locking rod 14 in resetting.
[0033] like Figure 1 and Figure 5As shown, in some embodiments, a workbench 17 is fixedly provided at the top front end of the base 1, and a cylinder 18 is fixedly provided on the side wall of the workbench 17. The output end of the cylinder 18 is connected to a movable seat 19, and the movable seat 19 is generally L-shaped.
[0034] When in use, after the spacing between the bending plates 12 is adjusted, the cylinder 18 fixed on the side wall of the workbench 17 pushes the moving seat 19 laterally. At this time, the top of the moving seat 19 moves laterally along the upper surface of the workbench 17, and the moving seats 19 on both sides move towards each other, which facilitates better support of the workpiece to be stamped and bent in the subsequent process.
[0035] like Figure 3 As shown, in some embodiments, the driving gear 7 is meshed with the driven gear 8 through teeth, and the driven gear 8 is symmetrically distributed along the vertical center line of the driving gear 7.
[0036] In use, since the driving gear 7 and the driven gear 8 are meshed, the rotation of the driving gear 7 can easily realize the rotation of the driven gear 8, and the rotation of the driven gear 8 can then realize the rotation of the bidirectional screw 9.
[0037] like Figure 3 As shown, in some embodiments, the inner side of the threaded sleeve 10 is provided with a threaded groove whose size is adapted to the outer diameter of the bidirectional screw 9, and the threaded sleeve 10 and the bidirectional screw 9 are connected by a thread through the threaded groove.
[0038] In use, since the threaded sleeve 10 and the bidirectional screw 9 are connected by a threaded groove, the position of the threaded sleeve 10 can be easily adjusted when the bidirectional screw 9 rotates, so that it can move axially along the bidirectional screw 9.
[0039] like Figure 4 As shown, in some embodiments, the locking rod 14 is slidably connected to the rotating wheel 6 via the auxiliary sliding plate 15, and the outer diameter of the locking rod 14 is adapted to the inner diameter of the lock hole 5;
[0040] When in use, the movement of the locking rod 14 will cause the auxiliary slide plate 15 to slide inside the rotating wheel 6. When one end of the locking rod 14 is inserted into the lock hole 5, the positioning of the rotating wheel 6 can be achieved.
[0041] In summary, during use, the workpiece to be processed is placed on the upper surface of the worktable 17. Then, the hydraulic cylinder 3 pushes the lower pressure seat 4, which in turn moves the bending plate 12, facilitating subsequent bending and stamping of the workpiece. When it is necessary to adjust the distance between the two bending plates 12, the locking rod 14 is pulled. This causes the auxiliary slide plate 15 to slide inside the rotating wheel 6. Then, one end of the locking rod 14 disengages from the inner side of the locking hole 5, facilitating the rotation of the rotating wheel 6. The rotating wheel 6 is then turned, causing the drive gear 7 to rotate. The rotation of the drive gear 7 then causes the driven gear 8 to rotate as well. The rotation of the two driven gears 8... The rotation of the bidirectional screw 9 is achieved by rotating the screw. Since the bidirectional screw 9 and the threaded sleeve 10 are connected by a threaded groove, the rotation of the bidirectional screw 9 can realize the movement of the threaded sleeve 10. At this time, the threaded sleeve 10 moves along the bidirectional screw 9 and pushes the push rod 11. Then the push rod 11 pushes the bending plate 12 to adjust the distance between the two bending plates 12. After the distance between the bending plates 12 is adjusted, the cylinder 18 fixed on the side wall of the worktable 17 works to push the moving seat 19 laterally. At this time, the top of the moving seat 19 moves laterally along the upper surface of the worktable 17, and the two moving seats 19 on both sides move towards each other, which facilitates better support of the workpiece to be stamped and bent in the subsequent process.
[0042] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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.
