Description

Technical Field

[0001] The utility model relates to the technical field of sheet metal processing, in particular to a strip sheet metal bending device for a numerical control machining center. Background Art

[0002] A sheet metal bending mechanism is a device for bending sheet metal, so as to obtain sheet metal parts at different angles for subsequent production and processing. It can be used independently or integrated in a numerical control machining center.

[0003] Chinese Patent Publication No. CN218963707U, published on May 5, 2023, discloses an adjustable sheet metal bending mechanism, including a support column. The upper end of the support column is provided with a support plate, the upper end of the support plate is provided with a mounting plate, an adjusting assembly for the distance between bending mechanisms is installed inside the mounting plate, a gantry is installed at the upper end of the mounting plate, a hydraulic cylinder is installed at the lower end inside the gantry, a pressing plate is installed at the lower end of the hydraulic cylinder, a lower pressing plate is installed at the upper end inside the gantry, and a pressing plate pressing-down assembly is installed on the side of the gantry.

[0004] For example, in the existing strip sheet metal bending device as above, by setting an adjusting assembly for the distance between bending mechanisms, this assembly can drive two groups of bidirectional lead screws to rotate through a motor, so as to drive two groups of symmetric sliding seats to approach or move away from each other, so that the distance between the two groups of bending mechanisms can be automatically adjusted. In the specific implementation process, when a strip sheet metal part is manually placed on two groups of matching frames at the same time, it is often impossible to quickly and accurately control the flat state of the strip sheet metal part, resulting in a relatively high risk of deviation in subsequent bending. And once deviation occurs, the overall strip sheet metal part will be scrapped. Therefore, it is urgent to propose a corresponding strip sheet metal bending device for a numerical control machining center to solve the above problems. Summary of the Utility Model

[0005] The purpose of the utility model is to propose a strip sheet metal bending device for a numerical control machining center in order to solve the above problems.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A strip sheet metal bending device for a numerical control machining center includes a chassis. Two groups of first sliding sleeves are slidably connected to the outer surface of the chassis, and a driving assembly for the relative movement of the two groups of first sliding sleeves is arranged inside the chassis. The tops of the two groups of first sliding sleeves are fixedly connected with gantries. A pushing cylinder and a matching seat are fixedly connected to the outer surfaces of the two groups of gantries. The output end of the pushing cylinder is fixedly connected with a pressing seat. Side frames are fixedly connected to the opposite surfaces of the two groups of gantries. A moving sleeve is fixedly connected to the outer surface of each of the two groups of side frames, and a retaining piece is fixedly connected to the top of the moving sleeve.

[0008] Preferably, the bottom parts of the two moving sleeves are respectively fixedly connected with a cross frame and a sliding frame, and the outer surface wall of the horizontal end of the sliding frame is slidably connected with the inner surface wall of the horizontal end of the cross frame.

[0009] Preferably, the inner surface wall of the moving sleeve is slidably connected with the outer surface wall of the side frame. The inner surface wall of the moving sleeve is screwed with a positioning rod, and the open end of the positioning rod abuts against the outer surface wall of the side frame.

[0010] Preferably, the longitudinal end of the side frame is fixedly connected with a mounting plate, and the mounting plate is fixedly connected with the gantry through a mounting rod.

[0011] Preferably, a spring and a shock absorber are integrated between the inner surface wall of the top of the gantry and the top of the pressure seat.

[0012] Preferably, the driving assembly includes a driving member fixedly connected with the outer surface wall of the bottom frame. The output end of the driving member is fixedly connected with a transmission rod. The outer surface wall of the transmission rod is screwed with two sets of screw sleeves through two sets of opposite thread grooves, and the two sets of screw sleeves are fixedly connected with two sets of sliding sleeves one.

[0015] 1. In this application, the driving member drives the transmission rod to rotate. The transmission rod is screwed with two sets of screw sleeves through two sets of opposite thread grooves on the outer surface wall. The two sets of screw sleeves drive the two gantries to move relative to each other through the two sets of sliding sleeves one until the distance between the two matching seats reaches the specified requirement. Then, the moving sleeve is pushed, and the moving sleeve slides along the side frame until the moving sleeve drives the baffle to move to a suitable position. Then, the positioning rod is rotated. While the positioning rod is screwed with the moving sleeve, its open end abuts against the outer surface wall of the side frame, so as to realize the positioning of the moving sleeve and the baffle. After that, the strip-shaped sheet metal part is placed on the tops of the two matching seats, so that the outer surface wall of the strip-shaped sheet metal part is attached to the baffle. At this time, the strip-shaped sheet metal part keeps a straight state. Finally, the bending of the strip-shaped sheet metal part is realized through the cooperation of the pushing cylinder and the pressure seat. Therefore, the position-adjustable baffle can not only not affect the bending process of the strip-shaped sheet metal part, but also enable the strip-shaped sheet metal part to quickly determine its position.

[0024] See also Figures 1-4 , the utility model provides a technical solution:

[0025] A strip sheet metal bending device for a CNC machining center includes a base frame 1, two sets of sliding sleeves 2 are slidably connected to the outer wall of the base frame 1, and a drive assembly for relative movement of the two sets of sliding sleeves 2 is provided inside the base frame 1, the tops of the two sets of sliding sleeves 2 are fixedly connected to a gantry frame 3, the outer walls of the two sets of gantry frames 3 are fixedly connected to a push cylinder 4 and a matching seat 13, and the output end of the push cylinder 4 is fixedly connected to a pressure seat 12, the opposite surfaces of the two sets of gantry frames 3 are fixedly connected to side frames 14, the outer walls of the two sets of side frames 14 are fixedly connected to moving sleeves 15, and the tops of the moving sleeves 15 are fixedly connected to a baffle 17;

[0026] The driving member drives the transmission rod 6 to rotate, and the transmission rod 6 is screwed with the two sets of screw sleeves 5 through the two sets of opposite thread grooves on the outer wall. The two sets of screw sleeves 5 drive the two sets of gantry frames 3 to move relative to each other through the two sets of sliding sleeves 12 until the spacing between the two sets of matching seats 13 reaches the specified requirement, and the moving sleeve 15 is pushed. The moving sleeve 15 slides along the side frame 14 until the moving sleeve 15 drives the baffle 17 to move to the appropriate position, and then the positioning rod 16 is rotated. At the same time, the positioning rod 16 is screwed with the moving sleeve 15, and its opening The end abuts against the outer wall of the side frame 14 to achieve the positioning of the movable sleeve 15 and the baffle 17. Subsequently, the strip sheet metal is placed on the top of the two sets of matching seats 13, so that the outer wall of the strip sheet metal is fitted with the baffle 17. At this time, the strip sheet metal remains flat. Finally, the bending of the strip sheet metal is achieved by the cooperation of the pushing cylinder 4 and the pressure seat 12. In this way, the setting of the position-adjustable baffle 17 does not affect the bending process of the strip sheet metal, but also enables the strip sheet metal to quickly determine its position.

[0027] Specifically, such as Figure 2 and Figure 4 As shown, the bottoms of the two groups of movable sleeves 15 are respectively fixedly connected with a cross frame 18 and a slide 19, and the outer wall of the horizontal end of the slide 19 is slidably connected to the inner wall of the horizontal end of the cross frame 18. The bottoms of the two groups of movable sleeves 15 are respectively fixedly connected with the cross frame 18 and the slide 19, and the slide 19 slides with the horizontal end of the cross frame 18. While fitting the relative movement of the two groups of gantry frames 3, the synchronous movement of the two groups of movable sleeves 15 can be achieved by dialing one group of movable sleeves 15, and the synchronous movement of the two groups of movable sleeves 15 can be achieved by tightening one group of movable sleeves 15. The positioning rod 16 can determine the longitudinal position of the two groups of movable sleeves 15, thereby improving the convenience of using the strip sheet metal bending device of the CNC machining center. The inner wall of the movable sleeve 15 is slidingly connected to the outer wall of the side frame 14, and the inner wall of the movable sleeve 15 is screwed together with the positioning rod 16, and the open end of the positioning rod 16 abuts against the outer wall of the side frame 14. When the positioning rod 16 is screwed together with the movable sleeve 15, its open end abuts against the outer wall of the side frame 14, thereby realizing the positioning of the movable sleeve 15 and the baffle 17.

[0028] Specifically, such as Figure 2 and Figure 3As shown, the longitudinal end of the side frame 14 is fixedly connected with a mounting plate 20, and the mounting plate 20 is fixedly connected to the gantry 3 through a mounting rod 21, so as to ensure the convenience of disassembly and assembly of the two sets of side frames 14, and a spring 10 and a shock absorber 11 are integrated between the top inner wall of the gantry 3 and the top of the pressure seat 12, so as to ensure the stability of the movement of the pressure seat 12.

[0029] Specifically, such as Figure 1 and Figure 2 As shown, the driving assembly includes a driving member fixedly connected to the outer wall of the base frame 1, and the output end of the driving member is fixedly connected to a transmission rod 6. The outer wall of the transmission rod 6 is screwed with two groups of screw sleeves 5 through two groups of opposite threaded grooves, and the two groups of screw sleeves 5 are fixedly connected to the two groups of sliding sleeves 2. The driving member drives the transmission rod 6 to rotate, and the transmission rod 6 is screwed with the two groups of screw sleeves 5 through the two groups of opposite threaded grooves on the outer wall. The two groups of screw sleeves 5 drive the two groups of gantries 3 to move relative to each other through the two groups of sliding sleeves 2, and the downward setting of the opening can avoid the intrusion of external impurities. The inner wall of the base frame 1 is fixedly connected with a polished rod 7, and the outer wall of the polished rod 7 is slidably connected with two groups of inner sleeves 9. The outer walls of the two groups of inner sleeves 9 are fixedly connected with a sliding sleeve 2 8 that is slidably connected to the outer wall of the base frame 1, and the outer walls of the two groups of sliding sleeves 2 8 are respectively fixedly connected to the two groups of gantries 3, so as to ensure that the two groups of gantries 3 are subjected to uniform force, further ensuring the stability of the movement of the two groups of gantries 3.

[0030] Working principle: The driving member drives the transmission rod 6 to rotate, and the transmission rod 6 is screwed with the two sets of screw sleeves 5 through two sets of opposite thread grooves on the outer wall. The two sets of screw sleeves 5 drive the two sets of gantry frames 3 to move relative to each other through two sets of sliding sleeves 1-2 until the spacing between the two sets of matching seats 13 reaches the specified requirement, and the moving sleeve 15 is pushed. The moving sleeve 15 slides along the side frame 14 until the moving sleeve 15 drives the baffle 17 to move to the appropriate position, and then the positioning rod 16 is rotated. At the same time, the positioning rod 16 is screwed with the moving sleeve 15. Its open end abuts against the outer wall of the side frame 14 to achieve the positioning of the movable sleeve 15 and the baffle 17. Subsequently, the strip sheet metal is placed on the top of the two sets of matching seats 13, so that the outer wall of the strip sheet metal is fitted with the baffle 17. At this time, the strip sheet metal remains straight. Finally, the bending of the strip sheet metal is achieved by the cooperation of the pushing cylinder 4 and the pressure seat 12. In this way, the setting of the position-adjustable baffle 17 does not affect the bending process of the strip sheet metal, but also enables the strip sheet metal to be quickly positioned.

[0031] The bottoms of the two groups of movable sleeves 15 are fixedly connected to the cross frame 18 and the slide 19 respectively, and the slide 19 slides with the horizontal end of the cross frame 18, thereby fitting the relative movement of the two groups of gantries 3. At the same time, the synchronous movement of the two groups of movable sleeves 15 can be achieved by shifting one group of movable sleeves 15, and the longitudinal positions of the two groups of movable sleeves 15 can be determined by tightening the positioning rod 16 on one group of movable sleeves 15, thereby improving the convenience of using the strip sheet metal bending device of the CNC machining center.
