Description

Technical Field

[0001] This invention relates to the field of stainless steel processing technology, and in particular to a flip-type bending device for stainless steel processing. Background Technology

[0002] During the production and processing of stainless steel, both ends are often bent as needed to obtain steel parts of the desired shape (one end upward and one end downward). However, in this process, the stainless steel (workpiece) needs to be clamped first, then one end is bent, and after bending one end, it is removed and placed back, and then clamped and bent again. This operation is inconvenient and takes a relatively long time, reducing the efficiency of bending such steel parts. To address this problem, we propose a flip-type bending device for stainless steel processing. Summary of the Invention

[0003] The purpose of this invention is to solve the problems mentioned in the background art by providing a flip-type bending device for stainless steel processing.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A flip-type bending device for stainless steel processing includes a workpiece and a base. An mounting plate is fixedly installed on the base. A servo motor is fixedly installed on the rear side of the mounting plate via a strip support plate. A drive shaft is fixedly installed on the drive end of the servo motor. One end of the drive shaft passes through the mounting plate and is fixedly installed with a rotating disk. A connecting component is installed between the rotating disk and the mounting plate.

[0006] A fixed clamping plate and two support blocks are fixedly installed on the front side of the rotating disk, and the workpiece is placed on the fixed clamping plate. A reciprocating screw is rotatably installed between the two support blocks. A movable clamping plate is installed on the reciprocating screw through a lifting component. A drive shaft is rotatably installed on the rotating disk, and the two ends of the drive shaft are located on both sides of the rotating disk. A first transmission component is installed between the drive shaft and the drive shaft, and a second transmission component is installed between the drive shaft and the reciprocating screw.

[0007] A circular groove is provided on one side of the mounting plate. A cylinder is fixedly installed in the circular groove. A telescopic rod is installed on one side of the cylinder. A mounting frame is fixedly installed at the end of the telescopic rod outside the mounting plate. A servo motor is installed on the mounting frame via a moving component. A rotating shaft is fixedly installed at the drive end of the servo motor. A support roller that cooperates with the workpiece is rotatably sleeved on the rotating shaft. An arc-shaped plate is fixedly installed on the rotating shaft. Two bent plates are fixedly installed on the front side of the arc-shaped plate.

[0008] In the above-mentioned stainless steel processing flip-type bending device, the connecting component is composed of an annular groove and an arc-shaped block. The rotating disk has an annular groove on the side near the mounting plate, and an arc-shaped block that matches the annular groove is fixedly installed on the front side of the mounting plate.

[0009] In the above-mentioned stainless steel processing flip-type bending device, the lifting component consists of a ball nut, a lifting seat and connecting rods. A lifting seat is installed on the reciprocating screw through the ball nut, and two connecting rods are fixedly installed on the lifting seat. The lower ends of the two connecting rods are fixedly connected to the upper surface of the movable clamping plate.

[0010] In the above-mentioned stainless steel processing flip-type bending device, the first transmission component consists of a transmission wheel, a one-way bearing, and a transmission belt. The transmission wheel is fixedly installed at one end of the transmission shaft behind the rotating disk. A transmission wheel is also installed on the drive shaft through a one-way bearing. A transmission belt is sleeved between the two transmission wheels.

[0011] In the above-mentioned stainless steel processing flip-type bending device, the second transmission component consists of a helical gear one and a helical gear two. The transmission shaft is fixedly mounted on the front end of the rotating disk with helical gear one, and the reciprocating screw is fixedly mounted with helical gear two that meshes with helical gear one.

[0012] In the above-mentioned stainless steel processing flip-type bending device, the moving component consists of a mounting groove, a second servo motor, a threaded rod, a moving seat, a limiting plate, a strip-shaped through hole, and a strip-shaped connecting groove. The mounting frame has a mounting groove, and the second servo motor is fixedly mounted on the mounting frame. A threaded rod is fixedly mounted on the drive end of the second servo motor. A moving seat is threadedly mounted on the threaded rod and slidably disposed in the mounting groove. A limiting plate is fixedly mounted in the mounting groove. The moving seat has a strip-shaped through hole that mates with the limiting plate. The moving seat is fixedly connected to the lower end face of the third servo motor. The front side of the mounting frame has a connecting groove that mates with the rotating shaft and is connected to the mounting groove.

[0013] In the above-mentioned stainless steel processing flip-type bending device, an arc-shaped support that cooperates with the rotating disk is fixedly installed on the front side of the mounting plate, and an arc-shaped elastic pad is fixedly installed on the upper end surface of the arc-shaped support.

[0014] In the above-mentioned stainless steel processing flip-type bending device, a counterweight is fixedly installed on the base, and the counterweight is located on the front side of the rotating disk.

[0015] Compared with existing technologies, the advantages of this invention are:

[0016] 1. A servo motor can drive the rotating disk to rotate when needed, and can also control the movement of the moving clamp in the vertical direction to apply clamping force to the placed workpiece, making the operation more convenient.

[0017] 2: The operation of servo motor three can drive the arc-shaped plate to rotate. The rotation of the arc-shaped plate can be used to bend one end of the workpiece. At the same time, the use of cylinder and servo motor two makes it easy to set this part without affecting the workpiece flipping as the rotating disk rotates.

[0018] 3: By using a one-way bearing, a first transmission component, and a second transmission component in combination, the servo motor can control the movement of the moving clamp in the vertical direction when it drives the drive shaft to rotate in the opposite direction, thus enabling better use.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Reference Figure 1-3 A stainless steel processing flip-type bending device includes a workpiece 21 and a base 1. A mounting plate 2 is fixedly installed on the base 1. A servo motor 4 is fixedly installed on the rear side of the mounting plate 2 through a strip support plate 3. A drive shaft 5 is fixedly installed on the drive end of the servo motor 4. One end of the drive shaft 5 passes through the mounting plate 2 and is fixedly installed with a rotating disk 6. A connecting component is installed between the rotating disk 6 and the mounting plate 2.

[0029] The following points are worth noting:

[0030] 1. The connecting component consists of an annular groove 17 and an arc-shaped block 18. An annular groove 17 is provided on the side of the rotating disk 6 near the mounting plate 2. An arc-shaped block 18 that matches the annular groove 17 is fixedly installed on the front side of the mounting plate 2.

[0031] The end face shapes of the annular groove 17 and the arc-shaped block 18 are both stepped, which gives the rotating disk 6 and the mounting plate 2 a supporting force in the front-to-back direction, thereby improving the stability between the rotating disk 6 and the mounting plate 2.

[0032] 2. An arc-shaped support 19 that cooperates with the rotating disk 6 is fixedly installed on the front side of the mounting plate 2, and an arc-shaped elastic pad is fixedly installed on the upper end surface of the arc-shaped support 19.

[0033] The arc-shaped support 19 provides a supporting force to the rotating disk 6 in the upper and lower positions. At the same time, by setting the arc-shaped elastic pad, the rotating disk 6 can be prevented from directly contacting the arc-shaped support 19, reducing the wear when the two rotate relative to each other.

[0034] The arc-shaped elastic pad can be made of rubber material. The elasticity of rubber can effectively reduce wear. The arc-shaped elastic pad can be fixed to the arc-shaped support 19 by gluing, so that it can be quickly replaced when damaged.

[0035] 3. A counterweight 20 is fixedly installed on the base 1, and the counterweight 20 is located on the front side of the rotating disk 6;

[0036] The weight of the counterweight 20 is used to keep the center of gravity of the device near the middle of the base 1, thereby improving the stability of the device during use.

[0037] 4. The drive shaft 5 and the rotating disk 6 can be directly fixed together, or they can be installed using a one-way bearing (the one-way bearing has the opposite self-locking direction to the one-way bearing in the first transmission component).

[0038] Reference Figure 1-3 as well as Figure 6 A fixed clamping plate 7 and two support blocks 8 are fixedly installed on the front side of the rotating disk 6, and the workpiece 21 is placed on the fixed clamping plate 7. A reciprocating screw 9 is rotatably installed between the two support blocks 8. A movable clamping plate 16 is installed on the reciprocating screw 9 through a lifting component. A transmission shaft 10 is rotatably installed on the rotating disk 6, and the two ends of the transmission shaft 10 are located on both sides of the rotating disk 6. A first transmission component is installed between the transmission shaft 10 and the drive shaft 5, and a second transmission component is installed between the transmission shaft 10 and the reciprocating screw 9.

[0039] The following points are worth noting:

[0040] 1. The lifting component consists of a ball nut, a lifting seat 14 and a connecting rod 15. A lifting seat 14 is installed on the reciprocating screw 9 through a ball nut. Two connecting rods 15 are fixedly installed on the lifting seat 14. The lower ends of the two connecting rods 15 are fixedly connected to the upper surface of the movable clamping plate 16.

[0041] Specifically, the lifting seat 14 has a cylindrical mounting hole, and the ball nut is specifically installed in the cylindrical mounting hole;

[0042] The lifting component is used to control the moving clamp 16 to move back and forth in the vertical direction. When the moving clamp 16 is at its lowest position during movement, it can provide stable support and fixation for the workpiece 21 placed on the fixed clamp 7.

[0043] 2. Rubber pads are fixedly installed on the upper surface of the fixed clamping plate 7 and the lower surface of the movable clamping plate 16. The rubber pads can improve the clamping and fixing of the workpiece 21 on the fixed clamping plate 7 and the movable clamping plate 16, and avoid direct contact between them, thereby improving mutual protection and reducing wear.

[0044] 3. The first transmission component consists of a transmission wheel, a one-way bearing, and a transmission belt 11. A transmission wheel is fixedly installed at one end of the transmission shaft 10 behind the rotating disk 6. A transmission wheel is also installed on the drive shaft 5 through a one-way bearing. A transmission belt 11 is fitted between the two transmission wheels.

[0045] The first transmission component is located between the mounting plate 2 and the rotating disk 6, so that when the drive shaft 5 drives the one-way bearing to rotate, the transmission shaft 10 can also rotate (when the drive shaft 4 rotates and drives the rotating disk 6 to rotate, the one-way bearing will not rotate).

[0046] 4. The second transmission component consists of helical gear 12 and helical gear 13. Helical gear 12 is fixedly installed on the front end of the transmission shaft 10 located on the rotating disk 6, and helical gear 13, which meshes with helical gear 12, is fixedly installed on the reciprocating screw 9.

[0047] The second transmission component is designed so that when the transmission shaft 10 rotates, it can drive the reciprocating screw 9 to rotate. The rotation of the reciprocating screw 9 can be used to control the lifting seat 14 to move back and forth in the vertical direction.

[0048] Reference Figure 1 , Figure 4 as well as Figure 5 A circular groove (not shown in the figure) is provided on one side of the mounting plate 2. A cylinder (not shown in the figure) is fixedly installed in the circular groove. A telescopic rod is installed on one side of the cylinder. A mounting frame 22 is fixedly installed at the end of the telescopic rod outside the mounting plate 2. A servo motor 28 is installed on the mounting frame 22 through a moving part. A rotating shaft 29 is fixedly installed at the drive end of the servo motor 28. A support roller (not shown in the figure) that cooperates with the workpiece 21 is rotatably sleeved on the rotating shaft 29. An arc-shaped plate 30 is fixedly installed on the rotating shaft 29. Two bent plates 31 are fixedly installed on the front side of the arc-shaped plate 30.

[0049] The following points are worth noting:

[0050] 1. The moving component consists of a mounting groove 23, a second servo motor 24, a threaded rod 25, a moving seat 26, a limiting plate 27, a strip-shaped through hole, and a strip-shaped connecting groove. The mounting frame 22 has a mounting groove 23 on its upper part. The second servo motor 24 is fixedly mounted on the mounting frame 22. The drive end of the second servo motor 24 is fixedly mounted with a threaded rod 25. The moving seat 26 is threadedly mounted on the threaded rod 25 and is slidably disposed in the mounting groove 23. The limiting plate 27 is fixedly mounted in the mounting groove 23. The moving seat 26 has a strip-shaped through hole that cooperates with the limiting plate 27. The moving seat 26 is fixedly connected to the lower end face of the third servo motor 28. The front side of the mounting frame 22 has a connecting groove that cooperates with the rotating shaft 29 and is connected to the mounting groove 23.

[0051] 2. Rubber pads are also fixedly installed on the side of the two bent plates 31 that are close to each other, so as to avoid direct contact with the workpiece 21.

[0052] 3. The arc-shaped plate 30 is located on the front side of the mounting bracket 22, and its rotation and subsequent movement in the digital direction will not come into contact with the mounting bracket 22.

[0053] To further clarify, the aforementioned fixed connection should be interpreted broadly unless otherwise explicitly specified and limited. For example, it may be welding, gluing, or integral molding, or other conventional methods well known to those skilled in the art.

[0054] In this invention, Figure 1 The diagram shows the state of workpiece 21 after it has been placed. At this time, the moving clamping plate 16 has clamped and fixed workpiece 21. Servo motor 3 28 is turned on. Servo motor 3 28 drives the arc plate 30 to rotate through the rotating shaft 29. The rotation of the arc plate 30 causes the bending plate 31 to apply a bending effect to the clamped end (achieved in cooperation with the support roller). After rotating 90°, servo motor 3 28 stops working. Servo motor 2 24 is turned on. Servo motor 2 24 drives servo motor 3 28 to move downward through the cooperation of the threaded rod 25 and the limiting plate 27, thereby separating the bending plate 31 from workpiece 21 and moving it below it.

[0055] Turn on servo motor 4. Servo motor 4 drives the rotating disk 6 to rotate via the drive shaft 5 (at this time, the one-way bearing is in a rotatable state). The rotation of the rotating disk 6, through the cooperation of the fixed clamping plate 7 and the movable clamping plate 16, enables the workpiece 21 to rotate 180°. After the workpiece 21 has rotated 180° with the rotating disk 6, turn off servo motor 4.

[0056] First, the cylinder is activated, which causes the telescopic rod to extend, thereby moving the components mounted on the mounting bracket 22. Then, servo motors 24 and 28 are activated, causing the arc-shaped plate 30 to rotate to its initial state, and simultaneously moving the movable base 26 to its initial state. Figure 5 (As shown), then the telescopic rod is retracted by the cylinder, so that one side of the mounting bracket 22 is re-attached to the mounting plate 2. Figure 1 As shown, the workpiece 21 can then be bent at that end.

[0057] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
