Description

Technical Field

[0001] This invention relates to the field of bending blade technology, specifically a bidirectional bending device. Background Technology

[0002] In the existing technology, bidirectional bending of a sheet metal refers to the ability of a sheet metal to be bent in two directions in sequence during a single clamping process through the structural design or program control of a bending equipment. This can be bending upwards simultaneously, bending downwards simultaneously, or bending in different directions simultaneously.

[0003] This type of bidirectional bending device is suitable for bending engineering parts with shapes such as U-shaped or Z-shaped structures, and can effectively improve the bending efficiency of sheet metal.

[0004] The technical structure of existing bidirectional bending devices, such as the "a bidirectional bending device" disclosed in Publication (Announcement) No.: CN102825112A, can bend multiple steel bars simultaneously, and both ends of the steel bars can be bent simultaneously without disassembling and reinstalling them. This one-time forming greatly reduces processing time and improves processing efficiency. The bidirectional bending device has a simple structure, low equipment requirements, and a high degree of automation, which greatly reduces production costs.

[0005] For example, the "bidirectional sliding bending structure device" disclosed in Publication (Announcement) No. CN217044365U is a technical solution that uses bidirectional movement between the sliding member and the slide groove to make the bent workpiece detach from the forming block, thereby achieving smooth unloading of the workpiece.

[0006] The bending mechanisms in the above-mentioned technical solutions and existing technical solutions still have certain problems when realizing bidirectional bending. The first problem is the width of the plate during bidirectional bending. In most existing technologies, the width of the plate after bending is not adjustable, and it can only achieve bending of a plate of one size, which is not reasonable enough.

[0007] Another issue is the feeding and unloading of the plates. In existing technologies, the plates are often placed on a bending machine for bending and then removed. Then a new plate is placed for bending, which leads to a serious decrease in work efficiency, makes it impossible to feed and unload the plates, and the structural design is not reasonable enough.

[0008] Therefore, in order to solve the above problems, it is necessary to develop a bidirectional bending device with a reasonable structure, adjustable, and improved bending efficiency of the plate. Summary of the Invention

[0009] The purpose of this invention is to address the shortcomings of existing technologies by providing a bidirectional bending device; the technical solution is as follows: A bidirectional bending device includes a long strip-shaped feeding platform. One side of the feeding platform is designated as the inlet end, and the other side is designated as the outlet end. A base is also provided at the outlet end. The base is integrally installed with the feeding platform. Slide grooves are provided on both sides of the base, and a double-headed screw mechanism is installed in the middle of the base. The screws on both sides of the double-headed screw mechanism extend outward, and screw seats are correspondingly installed on both sides of the screws. A slider is correspondingly installed at the lower end of the screw seat. The slider is correspondingly embedded in the slide groove. Under the action of the double-headed screw mechanism, the screw seats on both sides can be synchronously driven to move inward or outward. Furthermore, both sides of the lead screw seat are equipped with lifting and bending mechanisms, and the main shafts of both lifting and bending mechanisms extend upwards, with bending heads installed at the shaft ends. A pressing mechanism is also provided above the discharge end. The main shaft of the pressing mechanism extends downward and a pressing seat is installed at the shaft end. A double-headed screw motor is installed in the middle of the pressing seat. The screws on both sides of the double-headed screw motor extend outward and screw seats are installed on both sides of the screws. A bending pressure block is installed at the lower end of the screw seats on both sides. When the plate to be bent is located at the discharge end, the pressing mechanism drives the bending blocks on both sides to press and fix the plate on the feeding table. At the same time, the bending heads on both sides below bend upward under the action of the lifting bending mechanism.

[0010] Furthermore, the bending head is configured as a bending pressure roller, which is installed on the upper end of the main shaft of the lifting and bending mechanism.

[0011] Furthermore, the double-headed lead screw mechanism on the base is provided in three evenly spaced groups, each group is provided with two lifting and bending mechanisms on the left and right, and a total of three lifting and bending mechanisms and bending heads are provided on the same side; and the lifting and bending mechanisms are all synchronously moving.

[0012] Furthermore, the pressing mechanism has three sets of double-headed lead screw motors, and each set of double-headed lead screw motors has bending blocks installed on the lead screw seats on both sides. The three bending blocks on the same side are set as a whole, and the three sets of double-headed lead screw motors move synchronously, driving the bending blocks of the whole structure on both sides to move inward or outward synchronously.

[0013] Furthermore, a bending pressure block is provided at the bottom of the lead screw seat, extending outward, and an arc-shaped bending surface is provided at the outer end face of the bending pressure block.

[0014] Furthermore, several vertically arranged rotary motors are installed on both sides of the feeding platform, and the main shafts of the rotary motors on both sides extend upwards, with rotary rollers correspondingly installed at the shaft ends. The rotary motors on both sides are arranged in parallel, and the rotary motors on the same side are evenly spaced. The distance between the rotary motors on both sides is adapted to the width of the plate to be bent. When the plate is placed at the feeding end of the feeding platform, the plate is clamped by the rotary rollers on both sides and moves on the feeding platform under the action of the rotary rollers on both sides, eventually moving to the discharge end position.

[0015] Furthermore, all the rotary motors are configured as stepper motors, and a receiving frame is installed at the discharge end of the feeding platform.

[0016] Furthermore, the rotating roller is also equipped with a soft pad, which clamps the middle plate.

[0017] Beneficial effects: The present invention has the following beneficial effects: 1) In this invention, the bending blocks on both sides at the top and the lifting bending mechanism and bending head on both sides at the bottom can realize the bidirectional bending of the body, and the two sides of the plate can be bent upwards at the same time, which effectively improves the bending efficiency. 2) The positions of the two bending blocks at the top and the two lifting bending mechanisms at the bottom in this invention are adjustable. Therefore, the bending width of the plate can be adjusted first by the two bending blocks at the top, and then the two lifting bending mechanisms at the bottom can be used to achieve simultaneous upward bending. This not only enables bidirectional bending but also allows for adjustment of the bending width, resulting in a reasonable structure. 3) In order to improve the overall bending effect and structural stability, three sets of double-headed screw assemblies are provided at both the upper and lower ends of this invention. The bending pressure block at the upper end is set as a whole, and the bending head at the lower end is set as a rolling bending pressure wheel. All of them move synchronously, making the structure more reasonable. 4) In this invention, by setting rotary motors on both sides of the feeding table and soft pads on the rotary motors, and by setting the distance between the two sides to match the width of the plate, the feeding and loading of the plate can be realized; and by setting the rotary motors to a stepping structure, the plate can be unloaded after the plate is bent. The structure is ingenious and reasonable. Attached Figure Description

[0019] The present invention will be further illustrated below with reference to the accompanying drawings and specific embodiments. These embodiments are implemented based on the technical solutions of the present invention, and it should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0020] like Figures 1 to 4 As shown, a bidirectional bending device includes a long strip-shaped feeding platform 1. One side of the feeding platform 1 is set as the feeding end 2, and the other side is set as the discharging end 3. A base 4 is also set at the discharging end 3. The base 4 is installed as an integral part of the feeding platform 1. Slide grooves 5 are extended on both sides of the base 4, and a double-headed screw mechanism 6 is installed in the middle of the base 4. The screws 7 on both sides of the double-headed screw mechanism 6 extend outward, and screw seats 8 are installed on both sides of the screw 7. A slider 9 is installed at the lower end of the screw seat 8. The slider 9 is embedded in the slide groove 5. Under the action of the double-headed screw mechanism 6, the screw seats 8 on both sides can be moved inward or outward simultaneously. Furthermore, both sides of the lead screw seat 8 are equipped with lifting and bending mechanisms 10. The main shafts of both sides of the lifting and bending mechanisms 10 extend upwards, and bending heads 11 are installed at the shaft ends. A pressing mechanism 12 is also provided above the discharge end 3. The main shaft of the pressing mechanism 12 extends downward and a pressing seat 13 is installed at the shaft end. A double-headed screw motor 14 is installed in the middle of the pressing seat 13. The screws 7 on both sides of the double-headed screw motor 14 extend outward, and screw seats 8 are installed on both sides of the screws 7. The lower ends of the screw seats 8 on both sides are correspondingly installed with bending pressure blocks 15. When the plate 21 to be bent is located at the discharge end 3, the pressing mechanism 12 drives the bending blocks 15 on both sides to press and fix the plate 21 on the feeding table 1. At the same time, the bending heads 11 on both sides below bend upward under the drive of the lifting bending mechanism 10.

[0021] The bending head 11 is configured as a bending pressure roller, which is installed on the upper end of the main shaft of the lifting bending mechanism 10.

[0022] The base 4 has three evenly spaced sets of double-headed lead screw mechanisms 6. Each set has two lifting and bending mechanisms 10 on the left and right sides. There are a total of three lifting and bending mechanisms 10 and bending heads 11 on the same side. All lifting and bending mechanisms 10 move synchronously.

[0023] The pressing mechanism 12 has three sets of double-headed lead screw motors 14, and each set of double-headed lead screw motors 14 has a bending block 15 installed on the lead screw seat 8 on both sides. The three bending blocks 15 on the same side are set as a whole, and the three sets of double-headed lead screw motors 14 move synchronously, driving the bending blocks 15 of the whole structure on both sides to move inward or outward synchronously.

[0024] A bending block 15 is provided at the bottom of the lead screw seat 8 and extends outward, and an arc-shaped bending surface 16 is provided at the outer end face of the bending block 15.

[0025] Several vertically arranged rotary motors 17 are installed on both sides of the feeding table 1, and the main shafts of the rotary motors 17 on both sides extend upward, and rotary rollers 18 are installed on the shaft ends. The rotary motors 17 on both sides are arranged in parallel, and the rotary motors 17 on the same side are evenly spaced. The distance between the rotary motors 17 on both sides is adapted to the width of the plate 21 to be bent. When the plate 21 is placed on the feeding end 2 of the feeding table 1, the plate 21 is clamped by the rotary rollers 18 on both sides and moves on the feeding table 1 under the action of the rotary rollers 18 on both sides, and finally moves to the position of the discharge end 3.

[0026] All rotary motors 17 are configured as stepper motors, and a receiving frame 19 is installed at the discharge end 3 of the feeding platform 1; the rotary roller 18 is also equipped with a soft pad 20, which clamps the middle plate 21.

[0027] The specific working process and working principle of this invention are as follows: Figure 4 As shown, in this invention, the plate is placed at the feeding end of the feeding table. The rotating motors on both sides rotate accordingly under the drive of the rotating rollers. The distance between the rotating rollers on both sides is adapted to the width of the plate. A soft pad is also provided on the rotating rollers. The plate is sandwiched in the middle by the rotating rollers. Under the action of the rotating rollers, the plate is driven to move towards the discharge end. The rotating motors are set in a stepping manner, and the plate is fed step by step to the feeding end.

[0028] At the feeding end, the rotary motor will stop accordingly. At this point, the upper pressing mechanism first moves the lower pressing seat downwards, pressing the bending blocks on both sides onto the lower plate, thus fixing the plate on the feeding table. Then, the lower lifting and bending mechanism is activated, causing the bending head at the upper end of the mechanism to move upwards, thereby lifting both ends of the plate upwards to achieve bending. Figure 3 As shown, the bending block itself has an arc-shaped bending surface on the outer end. When it is pushed upward by the bending head below, it naturally pushes up both sides of the plate, thereby achieving bidirectional bending work on both sides at the same time and improving work efficiency.

[0029] After bending is completed, the plate is first lifted upward by the pressing mechanism and removed from the plate. The subsequent plates on the feeding platform will still move forward under the action of the rotating rollers on both sides, thus pushing the plate that has been bent at the discharge end forward and then falling into the receiving frame at the front end to realize the unloading of the bent plate.

[0030] In the above process, both the position of the upper bending blocks and the position of the lower lifting bending mechanism are adjustable. Both can be adjusted bidirectionally through the combination structure of the double-headed screw motor. This allows for adjustment based on the specific width of the plate to be bent. First, the position of the two upper bending blocks can be adjusted according to the bending width. After the bending blocks are adjusted, the position of the lower lifting bending mechanisms on both sides can be adjusted so that the bending heads on both sides are located on the outer side of the bending blocks. Then, the bending heads can be lifted upward by the lifting bending mechanisms to achieve bending. Therefore, the overall bending width is adjustable, and the bending work on both sides of the plate can be completed.

[0031] In addition, in order to improve the overall bending effect and structural stability, three sets of double-headed screw assemblies are provided at both the upper and lower ends of this invention. The bending pressure block at the upper end is integrated, and the bending head at the lower end is a rolling bending pressure wheel. All of them move synchronously, making the structure more reasonable.

[0032] The above-described specific embodiments are merely preferred embodiments of the present invention and are not intended to limit the implementation of the present invention or the scope of the claims. All equivalent changes and modifications made in accordance with the scope of patent protection of the present invention should be included within the scope of the present invention patent application.
