Abstract
Description
Technical Field
[0001] This utility model relates to the field of sheet metal production equipment technology, and in particular to a quick positioning sheet metal bending device. Background Technology
[0002] Sheet metal parts are products manufactured using sheet metal processing techniques. We rely on sheet metal parts everywhere in our lives. Sheet metal parts are characterized by their light weight, high strength, conductivity (which can be used for electromagnetic shielding), low cost, and good mass production performance. They are widely used in fields such as electronics, communications, automotive, and medical devices. For example, sheet metal parts are an essential component in computer cases, mobile phones, and MP3 players. Sheet metal parts need to be bent during use.
[0003] Patent number CN217369883U relates to a sheet metal bending quick positioning mechanism, which includes a mounting base. A bending die is mounted on the top of the mounting base. A sliding component for positioning sheet metal parts is provided on the top of the mounting base. A fixed plate is mounted on the top of the mounting base, located in front of the bending die. The fixed plate has a sliding groove inside, which is T-shaped. A pair of moving plates are slidably connected inside the sliding groove, and the side ends of both moving plates extend out of the sliding groove. A correction plate is fixedly connected to the end of each moving plate away from the sliding groove. An insertion component for locking the moving plates is provided inside each of the two moving plates. This achieves quick positioning of sheet metal parts, and the positioned sheet metal is restricted by the two correction plates, which effectively increases the accuracy of sheet metal bending and avoids the problem of low efficiency in manual positioning of sheet metal parts.
[0004] However, this patented technology also has the following drawbacks: the bending mold in this patented technology is fixed, which makes the bending angle of the sheet metal parts fixed and unable to be changed, thus limiting its applicability. Utility Model Content
[0005] In view of the above technical problems, this utility model provides a quick positioning sheet metal bending device that can change the bending angle.
[0006] This utility model provides a rapid positioning sheet metal bending device, including a working frame. The working frame is characterized by a hydraulic cylinder fixedly connected to its top inner side, a connecting head threadedly connected to the telescopic end of the hydraulic cylinder, a fixed plate fixedly connected to the bottom of the connecting head, a bending top piece fixedly connected to the bottom of the fixed plate, a base plate fixedly connected to its bottom inner side, damping spring shock absorbers connected to the left and right sides of the base plate, a placement plate with a through hole in its center, and a bending seat fixedly connected to the center of the base plate, the bending seat contacting a rotating column.
[0007] The surfaces of the bending seat and the rotating column are smoothed, and the rotating column can rotate within the bending seat under the action of external force.
[0008] Both the bending seat and the rotating column are disposed inside the through hole of the placement plate, and the inner surface of the through hole is in contact with the surface of the bending seat and the surface of the rotating column.
[0009] The bending seat is provided with an installation groove, and the rotating column rotates within the installation groove.
[0010] The rotating column is provided with a bending groove.
[0011] The beneficial effects of this utility model are as follows: This utility model is a quick positioning sheet metal bending device. It connects the base and the placement plate through a damping spring shock absorber, and sets a bending seat in the middle of the base. A rotating column is set inside the bending seat. The bending seat and the rotating column extend out of the through hole of the placement plate. The part to be bent is placed on the placement plate, and the bending top part is moved down by the hydraulic cylinder. At the same time, the rotating column rotates, so that the part to be bent is bent in the bending groove of the rotating column. The extension distance of the hydraulic cylinder is controlled to change the rotation angle of the rotating column, thereby realizing different bending angles of the part to be bent. The position of the bending groove of the rotating column and the through hole of the placement plate can play a positioning role for the sheet metal part. The part of the sheet metal part to be bent can be placed in the bending groove. Attached Figure Description

Detailed Implementation
[0023] Example 1
[0024] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings.
[0025] like Figure 1 , 2 As shown, this utility model provides a quick positioning sheet metal bending device, including a working frame 1. The working frame 1 is characterized by a hydraulic cylinder 2 fixedly connected to the top inner side of the working frame 1, a connecting head 3 threadedly connected to the telescopic end of the hydraulic cylinder 2, a fixing plate 4 fixedly connected to the bottom of the connecting head 3, a bending top piece 5 fixedly connected to the bottom of the fixing plate 4, a base plate 8 fixedly connected to the bottom inner side of the working frame 1, damping spring shock absorbers 7 connected to the left and right sides of the base plate 8 respectively, the top of the damping spring shock absorbers 7 connected to a placement plate 6, a through hole provided in the middle of the placement plate 6, and a bending seat 9 fixedly connected to the middle of the base plate 8, the bending seat 9 contacting a rotating column 10.
[0026] The surfaces of the bending seat 9 and the rotating column 10 are smoothed, and the rotating column 10 can rotate within the bending seat 9 under the action of external force.
[0027] Both the bending seat 9 and the rotating column 10 are located inside the through hole of the placement plate 6, and the inner surface of the through hole is in contact with the surface of the bending seat 9 and the surface of the rotating column 10.
[0028] The bending seat 9 is provided with a mounting groove 91, and the rotating column 10 rotates within the mounting groove 91.
[0029] A bending groove 101 is provided on the rotating column 10.
[0030] Example 2
[0031] In use, the sheet metal part 11 is placed on a placement tray. The sheet metal part 11 has a folded plate 111 in the middle to be bent. The folded plate 111 is placed in the bending groove 101 of the rotating column 10. The hydraulic cylinder 2 is started, and the hydraulic cylinder 2 drives the bending top piece 5 to move downward. When it moves to the surface of the sheet metal part 11, it continues to press down. At this time, the placement tray 6 moves down under the action of the damping spring shock absorber 7. At the same time, the rotating column 10 rotates in the bending seat 9. While rotating, the bending work of the sheet metal part 11 is realized. When it moves down to the lowest point and the bending is completed, the hydraulic cylinder 2 retracts, the damping spring shock absorber 7 slowly rebounds, and the rotating column 10 rotates in the opposite direction to return to its original position. At this time, the bending work is completed.
[0032] The initial position of the rotating column 10 within the bending seat 9 is as follows: Figure 9 As shown, the rotating column 10 is in equilibrium. When it is pressed down, the rotating column 10 rotates as follows: Figure 10 As shown, once the bending is complete, the rotating column 10 is no longer under pressure and will automatically regain its balance, rotating until... Figure 9 The rotational speed of the damping spring shock absorber 7 is matched with the rebound speed of the damping spring shock absorber 7 to achieve return to its original position.
