Description

Technical Field

[0001] The present invention relates to the technical field of folding bending knives, and more specifically to a continuous V-shaped bending mechanism. Background Art

[0002] In the prior art, the most common bending method for a plate body during bending is to bend it into a V-shaped structure. The V-shaped structure can be applied to many mechanical parts. For example, in the machining of machine tools such as lathes, grinders, and milling machines in mechanical equipment, it is used for the positioning and clamping of rotating workpieces such as cylindrical, shaft-like, and pipe-like workpieces.

[0003] For the structure of the V-shaped bending mechanism in the prior art, for example: the "V-shaped bending die" disclosed in the publication (announcement) number: CN102989903A. In this technical solution, it can effectively reduce the scratches and deformations caused by extrusion friction during the processing of the bending forming die to the processed parts, and extend the service life of the bending forming die.

[0004] For example: the "V-shaped bending mechanism with double-sided folding" disclosed in the publication (announcement) number: CN106513466A. In this technical solution, by driving the turning plate to turn by a double-rod piston cylinder, the bending of the thin plate can be completed, changing the force position and force direction of the thin plate, ensuring the performance of the plate at the bending part. During the process, the labor intensity of workers is small, time and labor are saved, and the work efficiency is high.

[0005] However, there are usually many problems in the above technical solutions and the existing technical solutions. First of all, when the plate body is specifically bent, there may still be a flat plate structure with a certain length on both sides of the V-shaped structure. If the flat plate structures on both sides are pressed tightly during bending, it may lead to bending failure.

[0006] In addition, during bending, the plate body will be dragged on both sides of the V-shaped groove, resulting in dragging marks on the plate body, seriously affecting the bending quality.

[0007] The most important point is that the bending mechanisms in the prior art all perform bending individually. After bending one workpiece, the workpiece is taken out and a new workpiece is put in, and a continuous bending operation cannot be formed, resulting in low work efficiency.

[0008] Therefore, in order to solve the above problems, it is necessary to develop a continuous V-shaped bending mechanism with a reasonable structure and capable of improving the bending power. Summary of the Invention

[0009] The purpose of the present invention is to provide a continuous V-shaped bending mechanism in view of the deficiencies of the prior art. The technical solution is as follows: A continuous V-shaped bending mechanism includes a long strip-shaped fixed base and a pressing mechanism located at the upper end of one side of the fixed base and cooperating with the fixed base. A V-shaped bending groove is provided on the fixed base, and the main shaft of the pressing mechanism extends downward and a pressing seat is installed at the shaft end. A triangular bending press block adapted to the shape of the bending groove is further provided on the pressing seat; A number of rows of balls are also installed on the fixed base. The balls are arranged on both sides of the bending groove, and a driving mechanism is embedded in the fixed base. When the plate body is placed at the other end of the fixed base, under the action of the driving mechanism, the plate body slides on the balls and thus moves to the lower part of the pressing mechanism, and is pressed into a V shape by the bending press block.

[0010] Furthermore, balls are also installed on the lower end surface of the pressing seat, and the balls are arranged on both sides of the bending press block.

[0011] Furthermore, circular mounting grooves are provided on both the pressing seat and the fixed base. The balls are correspondingly embedded in the mounting grooves, and the balls leak out from the mounting grooves, and the balls will not fall out of the mounting grooves.

[0012] Furthermore, the driving mechanism includes a sealed cavity provided inside the fixed base. There are two sealed cavities on the left and right in the fixed base, and both are located below the balls; two driving rollers are correspondingly installed on the front and rear sides of each sealed cavity, and a rigid conveyor belt is correspondingly installed between the two driving rollers. The width of the driving rollers is set to be the same as the width of the sealed cavity, and the area between the two driving rollers is set as a suction area; An air suction pipe that rotates together with the rigid conveyor belt is also installed on the rigid conveyor belt. The air suction pipes are arranged in several columns on the rigid conveyor belt, and the distance between adjacent air suction pipes in each column is the same. Each air suction pipe is communicated with the suction area; an annular groove extending outward is also provided on the inner wall of the cavity of the sealed cavity. The position of the annular groove corresponds to the position of the air suction pipe, and the upper slot opening of the annular groove extends to the upper end surface of the fixed base, and the upper slot opening is located between two adjacent rows of balls; An air suction mechanism is also installed outside the fixed base. The air suction mechanism is connected to the suction area in the sealed cavity through an air suction pipe. When the driving roller rotates, it drives the air suction pipe to rotate around the annular groove. When the air suction pipe rotates to the upper end of the annular groove, the upper pipe orifice of the air suction pipe extends out from the upper slot opening, and under the action of the air suction mechanism, the air suction pipe generates suction. When the plate body to be bent is placed on the air suction pipe, the plate body moves along with the air suction pipe.

[0013] Furthermore, a flared opening is provided at the pipe orifice of the air suction pipe, and the height of the flared opening is set to be flush with the upper end surface of the balls in the fixed base.

[0014] Furthermore, drive motors are installed on both sides of the fixed base. The drive motors are connected to the drive rollers, and the other side of the drive rollers is correspondingly installed in the sealing cavity through bearing parts; and the drive motors are set in a stepper drive form.

[0015] Furthermore, a controller is also included. The drive motors and the air suction mechanism are both connected to the controller, and the air suction mechanism and the drive motors are correspondingly controlled by the controller; and the air suction mechanism is set to be synchronously turned on and off with the stepper drive motors. When the drive motors are turned on, the air suction is turned on, and the air suction pipe located at the notch generates suction; when the drive motors stop, the air suction mechanism is turned off, and the suction of the air suction pipe located at the notch disappears.

[0016] Beneficial effects: The present invention has the following beneficial effects: 1) The present invention can realize the continuous operation of V-shaped bending of the plate body, with a reasonable structure, effectively improving the bending efficiency and bending quality; 2) By arranging the ball bearings in the up and down directions in the present invention, when specifically bending the plate body, the plate body can move correspondingly without causing scratches and deformation of the plate body; 3) In the present invention, through the arranged sealing cavity, drive rollers, hard conveyor belt, air suction pipes and corresponding annular grooves, continuous movement and feeding of the plate body can be realized, and continuous bending work can be achieved; 4) The design of the air suction pipes in the present invention is quite ingenious. On the one hand, by using the annular groove design, it can extend to the outside. Through the correspondingly arranged air suction mechanism, the plate body can be fixed correspondingly and can move along, with a very reasonable structural design; 5) In the present invention, the opening and closing of the drive motors and the air suction mechanism are reasonably set, and the two cooperate correspondingly to realize the continuous transmission and bending of the plate body, with a very reasonable structural design.

Specific implementation manner

[0018] The present invention will be further illustrated below in conjunction with the accompanying drawings and specific embodiments. These embodiments are implemented on the premise of the technical solution of the present invention, and it should be understood that these embodiments are only used to illustrate the present invention and not to limit the scope of the present invention.

[0019] As Figures 1 to 4 shown, a continuous V-shaped bending mechanism includes a long strip-shaped fixed base 1 and a pressing mechanism 2 located at the upper end of one side of the fixed base 1 and cooperating with the fixed base 1. A V-shaped bending groove 3 is provided on the fixed base 1, and the main shaft of the pressing mechanism 2 extends downward and a pressing seat 4 is installed at the shaft end. A triangular bending pressure block 5 adapted to the shape of the bending groove 3 is further provided on the pressing seat 4; A number of rows of balls 6 are also installed on the fixed base 1. The balls 6 are arranged on both sides of the bending groove 3, and a driving mechanism is embedded in the fixed base 1. When the plate body 8 is placed at the other end of the fixed base 1, under the action of the driving mechanism, the plate body 8 slides on the balls 6 and thus moves to the lower part of the pressing mechanism 2 and is pressed into a V shape by the bending pressure block 5.

[0020] Balls 6 are also installed on the lower end surface of the pressing seat 4, and the balls 6 are arranged on both sides of the bending pressure block 5.

[0021] Circular mounting grooves 9 are provided on both the pressing seat 4 and the fixed base 1. The balls 6 are correspondingly embedded in the mounting grooves 9, and the balls 6 leak out from the mounting grooves 9, and the balls 6 will not fall out of the mounting grooves 9.

[0022] The driving mechanism includes a sealed cavity 10 provided inside the fixed base 1. There are two sealed cavities 10 on the left and right in the fixed base 1, and both are located below the balls 6; Two driving rollers 11 are correspondingly installed on the front and rear sides of each sealed cavity 10, and a rigid conveyor belt 12 is correspondingly installed between the two driving rollers 11. The width of the driving rollers 11 is set to be the same as the width of the sealed cavity 10, and the area between the two driving rollers 11 is set as a suction area 13; An air suction pipe 14 rotating together with the rigid conveyor belt 12 is also installed on the rigid conveyor belt 12. The air suction pipes 14 are arranged in several columns on the rigid conveyor belt 12. The distance between adjacent air suction pipes 14 in each column is the same, and each air suction pipe 14 is communicated with the suction area 13; An annular groove 15 extending outward is also provided on the inner wall of the cavity of the sealed cavity 10. The position of the annular groove 15 corresponds to the position of the air suction pipe 14, and the upper slot opening 16 of the annular groove 15 extends to the upper end surface of the fixed base 1, and the upper slot opening 16 is located between two adjacent rows of balls 6; An air suction mechanism 17 is also installed outside the fixed base 1. The air suction mechanism 17 is connected to the air suction area 13 in the sealing cavity 10 through an air suction pipe 14. When the driving roller 11 rotates, it drives the air suction pipe 14 to rotate around the annular groove 15. When the air suction pipe 14 rotates to the upper end of the annular groove 15, the upper end pipe orifice of the air suction pipe 14 extends out from the upper notch 16, and under the action of the air suction mechanism 17, the air suction pipe 14 generates suction. When the plate body 8 to be bent is placed on the air suction pipe 14, the plate body 8 moves along with the air suction pipe 14.

[0023] A flared opening 18 is provided at the pipe orifice of the air suction pipe 14, and the height of the corresponding flared opening 18 is flush with the upper end surface of the ball 6 in the fixed base 1.

[0024] Driving motors 7 are also installed on both sides of the fixed base 1. The driving motors 7 are connected to the driving roller 11, and the other side of the driving roller 11 is correspondingly installed in the sealing cavity 10 through bearing parts; and the driving motors 7 are set in a stepper driving form.

[0025] It also includes a controller 19. Both the driving motor 7 and the air suction mechanism 17 are connected to the controller 19. The air suction mechanism 17 and the driving motor 7 are correspondingly controlled through the controller 19; and the air suction mechanism 17 is set to be synchronously started and stopped with the stepper driving motor 7. When the driving motor 7 is started, the air suction is started, and the air suction pipe 14 located at the notch 16 generates suction; when the driving motor 7 stops, the air suction mechanism 17 is closed, and the suction of the air suction pipe 14 located at the notch 16 disappears.

[0026] The specific working process of the present invention is as follows: The present invention first sets the air suction mechanism to be synchronously started and stopped with the stepper driving motor. When the stepper motor is started, the air suction is started, and the air suction pipe located at the notch generates suction; when the stepper motor stops, the air suction mechanism is closed, and the suction of the air suction pipe located at the notch disappears.

[0027] Then, during the specific operation, place the plate body at the feeding end of the fixed base. After the stepping motor is started, the driving rollers in the sealing cavity rotate correspondingly, driving the conveyor belt to rotate in the sealing cavity and simultaneously driving the air suction pipe to rotate in the annular groove. At this time, the air suction mechanism is also started accordingly. Since the sealing cavity itself is sealed, and the width of the driving roller is the same as the width of the sealing cavity, and the conveyor belt between the two driving rollers is a rigid conveyor belt, such as a rigid rubber conveyor belt, a rigid PU conveyor belt, a rigid PVC conveyor belt, etc., a suction area with certain sealing performance is formed in the area between the two driving rollers. When the air suction mechanism is started, it sucks air from the suction area. Since the air suction pipe is connected to the suction area, the air suction pipe will generate suction force. However, only the air suction pipe at the notch at the upper end will generate suction force because this part of the air suction pipe extends out of the annular groove, while the other air suction pipes are correspondingly arranged in the sealing cavity. During the rotation of the air suction pipe with the rigid conveyor belt, it is entirely located in the annular groove. When the air suction pipe rotates to the position of the opening at the upper end of the annular groove, since it extends out to the outside, a strong suction force will be generated. Therefore, when the plate body is placed at the feeding end of the fixed base, on the one hand, the plate body is supported by the balls, and on the other hand, it is fixed by the suction force generated by the air suction pipe. Moreover, the end of the air suction pipe is provided with a flared mouth, and the height of the flared mouth is set to be flush with the height of the balls, so it can be sucked by the flared mouth.

[0028] After that, the plate body can move forward accordingly. The air suction mechanism and the driving motor are both designed with intermittent operation, which is designed to balance the continuous movement of the plate body and subsequent bending. The plate body can move intermittently with the air suction pipe to directly below the pressing mechanism. When it reaches directly below the pressing mechanism, the driving motor stops, and at this time, the air suction mechanism also stops accordingly. Then, the pressing mechanism above moves downward, causing the bending block to press on the plate body and gradually pressing the plate body into the bending groove to complete the V-shaped bending.

[0029] During the above bending process, since balls are provided on both sides of the fixed base and the pressing seat, when the middle of the plate body is pressed downward under the support of the balls, the plate body can move inward correspondingly to prevent dragging marks and deformation. Moreover, the flat parts on both sides of the plate body will not be pressed because they are also supported by the balls and will move inward simultaneously. After the bending is completed, since in addition to the V-shaped part in the middle, the plate body of the present invention also has extended flat parts on both sides. When the driving motor is started, the air suction mechanism will also be started. At this time, the air suction pipe can still suck the extended flat parts on both sides, move the bent plate body to the front side, and at the same time, the plate body at the rear side is sent directly below the pressing seat to continue to complete the next bending operation. The overall structural design is very reasonable and ingenious.

All equivalent changes and modifications made according to the scope of the patent application for the present invention shall be included within the scope of the patent application for the present invention.
