Description

Technical Field

[0001] The utility model relates to the technical field of copper strip processing equipment, in particular to a copper strip continuous bending and forming device. Background Art

[0002] Copper strip has high strength, good electrical conductivity, thermal conductivity and corrosion resistance, and is suitable for electronic and electrical, shipbuilding, chemical industry and other fields.

[0003] Copper strips often need to be bent and formed during processing. After searching, the Chinese patent application number is: CN200620034693.7, which discloses a W-shaped continuous bending steel bar component forming device, aiming to provide a forming device with extremely high production efficiency and capable of forming steel bar components with standardized size and shape, so as to meet the needs of mass production of lightweight wall panels. It includes: a pair of parallel main shafts (11, 12), which are installed on the frame (10) through a bearing seat; a pair of matching gears (13, 14), which are respectively installed and fixed on the main shafts (11, 12); a driving device, which drives the main shafts (11, 12) to rotate in the opposite direction. The steel bars are continuously extruded by the gears (13, 14) rotating in the opposite direction so that they are continuously bent, forming a W-shaped continuously bent steel bar component.

[0004] The above technical solution lacks a positioning component and cannot be applied to copper strips. During the bending process, if the two sides of the bent part lack positioning, deformation will occur due to stress. In order to ensure that the copper strip maintains the shaping standard after bending, we need to propose a continuous bending device for copper strips. Utility Model Content

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figure 1-4 , the utility model provides a technical solution:

[0030] Copper strip continuous bending and forming device, comprising:

[0031] A base 1; a processing table 23 is provided on the base 1, a bending groove 24 for bending the copper strip is provided on the processing table 23, a first notch 2 is symmetrically provided on both sides of the processing table 23 on the base 1, and a conveying roller 3 for conveying the copper strip is rotatably installed in the first notch 2;

[0032] Molding mechanism; the molding mechanism includes a lifting plate 10 disposed just above the processing table 23, the lifting plate 10 is driven to lift by the motor 7, and a molding block 14 is mounted on the bottom of the lifting plate 10 by fixing screws, and the molding block 14 and the curved groove 24 are correspondingly arranged;

[0033] Two groups of support rods 4 are symmetrically arranged on the base 1, and a top plate 5 is arranged at the upper end of the support rods 4, and a motor 7 is fixedly installed on the top plate 5. A driving arm 8 is fixedly connected to the output end of the motor 7, and a connecting arm 9 is rotatably installed at the end of the driving arm 8. The top of the lifting plate 10 is symmetrically provided with protrusions 11, and a connecting rod 12 is arranged between the protrusions 11. The lower end of the connecting arm 9 is rotatably installed on the connecting rod 12. Guide plates 17 are symmetrically arranged at both ends of the lifting plate 10, and guide sleeves 18 are arranged at the ends of the guide plates 17. Two groups of guide sleeves 18 are slidably sleeved on the two groups of support rods 4 respectively.

[0034] The positioning mechanism is arranged on the lifting plate 10; the positioning mechanism includes a wheel seat 20 and a slide bar 19, a positioning wheel 21 is rotatably mounted at the bottom of the wheel seat 20, at least two groups of slide bars 19 are arranged on the top of the wheel seat 20, and the slide bars 19 are slidably inserted into the lifting plate 10. A limit block is arranged at the upper end of the slide bar 19, and two groups of rubber washers are sleeved on the slide bar 19 between the lifting plate 10 and the wheel seat 20, and a compression spring 22 is located between the two groups of rubber washers.

[0035] The copper strip is conveyed by arranging a conveying roller 3 on the base 1, a processing table 23 with a curved groove 24 is arranged on the base 1, a lifting plate 10 driven by a motor 7 is arranged above the processing table 23, a forming block 14 is installed at the bottom of the lifting plate 10, a positioning mechanism including a wheel seat 20 and a slide bar 19 is arranged on the lifting plate 10, a positioning wheel 21 is installed at the bottom of the wheel seat 20, the slide bar 19 is slidably plugged into the lifting plate 10, and a compression spring 22 is sleeved on the slide bar 19. In actual use, the steel strip is conveyed by the conveying roller 3. When the steel strip passes under the forming block 14, a second notch 6 for the movement of the driving arm 8 and the connecting arm 9 is opened on the top plate 5. The motor 7 converts the rotational motion into the up and down reciprocating motion of the lifting plate 10 through the cooperation of the driving arm 8 and the connecting arm 9. The forming block 14 at the bottom of the lifting plate 10 cooperates with the curved groove 24 on the processing table 23 to bend and shape the copper strip, and the formed copper strip continues to be conveyed forward to achieve continuous processing of the copper strip.

[0036] At the same time, when the lifting plate 10 drives the forming block 14 to descend to bend the copper strip, the height of the positioning wheel 21 is lower than the bottom height of the forming block 14, so the positioning wheel 21 will contact the two sides of the forming part of the copper strip, press the copper strip against the processing table 23, and then the forming block 14 presses the copper strip down to bend it;

[0037] When the copper strip is bent, both sides of the bent portion will retract toward the middle. The design of the positioning wheel 21 can not only prevent the edges of the bent portion from warping, but also play a role in dynamic positioning, and will not hinder the bending of the steel strip.

[0038] In general, the device has a simple structure and is easy to use. Through the cooperation of the positioning mechanism and the forming mechanism, the two sides of the bending part of the steel strip can be positioned when the steel strip is bent and formed, so as to avoid the warping of the steel strip and ensure the standard degree of bending and forming of the steel strip.

[0039] For further information, see Figure 3-4 :

[0040] Two groups of fixing plates 13 are symmetrically arranged at the bottom of the lifting plate 10, and two groups of mounting plates 15 corresponding to the fixing plates 13 are symmetrically arranged on the top of the forming block 14. Through holes for fixing screws to pass through are correspondingly opened on the mounting plates 15 and the fixing plates 13. When the mounting plates 15 and the fixing plates 13 are connected by fixing screws, the upper ends of the mounting plates 15 abut against the bottom of the lifting plate 10.

[0041] This design facilitates quick and convenient combination, use, and disassembly and maintenance of the forming block 14 and the lifting plate 10. At the same time, when the forming block 14 and the lifting plate 10 are combined by fixing screws, the upper end of the mounting plate 15 abuts against the bottom of the lifting plate 10, which can reduce the load on the fixing screws when the lifting plate 10 is pressed down, thereby facilitating long-term use of the equipment.

[0042] See also Figure 4 :

[0043] The bottom of the forming block 14 is in a downwardly convex arc shape, the arc-shaped inner wall of the curved groove 24 is adapted to the forming block 14, and pressing plates 16 are symmetrically arranged on both sides of the forming block 14, and a rubber pad is bonded and fixed to the bottom surface of the pressing plate 16.

[0044] By arranging a pressing plate 16 with a rubber pad on the forming block 14, when the forming block 14 presses the steel strip into the bending groove 24, the pressing plate 16 can press the steel strip on both sides of the bending groove 24 against the processing table 23, thereby shaping the connection between the bent part and the normal part, which is beneficial to improving the bending forming quality of the copper strip.
