Description

Technical Field

[0001] The present invention relates to the technical field of folding bending knives, and specifically relates to a two-way bending device. Background Art

[0002] In the prior art, the two-way bending of a plate body means that through the structural design or program control of a bending device, the plate can be bent in two directions in one clamping process, which can be bent upward simultaneously, or bent downward simultaneously, or bent in different directions simultaneously.

[0003] This type of two-way bending device is suitable for bending some shaped engineering parts such as U-shaped structures or Z-shaped structures, which can effectively improve the bending work efficiency of the plate body.

[0004] The technical structure of the two-way bending device in the prior art, for example: the "two-way bending device" disclosed in the publication (announcement) number: CN102825112A. This technical solution can bend multiple steel bars into shape simultaneously, and both ends of the steel bars can be bent into shape simultaneously without disassembling and reinstalling the steel bars, achieving one-time forming, greatly reducing the processing time, and improving the processing efficiency. This two-way bending device has a simple structure, low equipment requirements, and high automation, greatly reducing the production cost.

[0005] For example: the "two-way sliding bending structure device" disclosed in the publication (announcement) number: CN217044365U. This technical solution enables the bent workpiece to be separated from the forming block through the two-way movement between the sliding part and the sliding groove, thereby realizing the smooth unloading of the workpiece.

[0006] When the above technical solutions and the bending mechanisms in the prior art solutions achieve two-way bending, there are still certain problems. First, it is the width problem of the plate body during two-way bending. In the prior art, the width of the plate body after bending is not adjustable for most devices, and only the bending of a plate body of one size can be achieved, and the structure is not reasonable enough.

[0007] Another point is the feeding and discharging problems of the plate body. In the prior art, the plate body is mostly placed on a bending machine for bending and then taken off, and then a new plate body is placed for bending. This leads to a serious decline in work efficiency and cannot achieve the feeding and discharging of the plate body, and the structural setting is not reasonable enough.

[0008] Therefore, in order to solve the above problems, it is necessary to develop a two-way bending device with a reasonable structure, adjustable, and capable of improving the bending efficiency of the plate body. Summary of the Invention

Under the action of the double-headed screw rod mechanism, the screw rod seats on both sides can be synchronously driven to move inward or outward. Moreover, lifting and bending mechanisms are installed on both sides of the screw rod seats. The main shafts of the lifting and bending mechanisms on both sides extend upward, and bending heads are installed at the shaft ends. Above the discharging end, a pressing mechanism is also provided.

Bending pressing blocks are correspondingly installed at the lower ends of the screw rod seats on both sides. When the plate to be bent is located at the discharging end, the pressing mechanism drives the bending pressing 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 are driven by the lifting and bending mechanisms to bend upward.

[0010] Furthermore, the bending head is set as a bending pressure wheel, and the bending pressure wheel is correspondingly installed at the upper end of the main shaft of the lifting and bending mechanism.

[0011] Furthermore, a total of three groups of double-headed screw rod mechanisms on the base are arranged at evenly spaced intervals. Each group is provided with two lifting and bending mechanisms on the left and right. A total of three lifting and bending mechanisms and bending heads are arranged on the same side; and the lifting and bending mechanisms all move correspondingly and synchronously.

[0012] Furthermore, a total of three groups of double-headed screw rod motors in the pressing mechanism are provided.

The three bending pressing blocks on the same side are set as a whole, and the three groups of double-headed screw rod motors move synchronously, driving the bending pressing blocks of the overall structures on both sides to move inward or outward synchronously.

[0013] Furthermore, the bending pressing blocks are correspondingly set to extend outward at the bottom of the screw rod seats, and an arc-shaped bending surface is also provided at the outer end face of the bending pressing blocks.

[0014] Furthermore, a number of vertically arranged rotary motors are installed on both sides of the feeding table. The main shafts of the rotary motors on both sides extend upward, and rotary rollers are 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 set to be adapted to the width of the plate to be bent. When the plate is placed at the feeding end of the feeding table, the plate is correspondingly clamped by the rotary rollers on both sides and moves on the feeding table under the action of the rotary rollers on both sides, and finally moves to the discharging end position.

[0015] Furthermore, the rotary motors are all set to be of a stepper structure, and a receiving frame is also installed at the discharging end position of the feeding table.

Specific embodiments

[0019] 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.

[0020] As Figures 1 to 4 shown, a two-way bending device includes a long strip-shaped feeding table 1. One side of the feeding table 1 is set as a feeding end 2, and the other side is set as a discharging end 3. A base 4 is also provided at the discharging end 3. The base 4 is installed integrally with the feeding table 1. Sliding grooves 5 extend on both sides of the base 4, and a double-headed lead screw mechanism 6 is installed at the middle position of the base 4. The lead screws 7 on both sides of the double-headed lead screw mechanism 6 extend outward, and lead screw seats 8 are correspondingly installed on both lead screws 7. The lower ends of the lead screw seats 8 are correspondingly installed with sliders 9, and the sliders 9 are correspondingly embedded in the sliding grooves 5. Under the action of the double-headed lead screw mechanism 6, the lead screw seats 8 on both sides can be synchronously driven to move inward or outward. Moreover, lifting and bending mechanisms 10 are installed on both lead screw seats 8. The main shafts of the two lifting and bending mechanisms 10 on both sides extend upward, and bending heads 11 are installed at the shaft ends. A pressing mechanism 12 is also provided above the discharging 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 lead screw motor 14 is installed at the middle position of the pressing seat 13. The lead screws 7 on both sides of the double-headed lead screw motor 14 extend outward, and lead screw seats 8 are installed on both lead screws 7. The lower ends of the two lead screw seats 8 on both sides are correspondingly installed with bending pressing blocks 15. When the plate body 21 to be bent is located at the discharging end 3, the pressing mechanism 12 drives the bending pressing blocks 15 on both sides to press and fix the plate body 21 on the feeding table 1. At the same time, the bending heads 11 on both sides below are bent upward under the drive of the lifting and bending mechanisms 10.

[0021] The bending head 11 is set as a bending pressure wheel, and the bending pressure wheel is correspondingly installed at the upper end of the main shaft of the lifting and bending mechanism 10.

[0022] A total of three groups of double-headed lead screw mechanisms 6 on the base 4 are provided at evenly spaced intervals. Each group is provided with two lifting and bending mechanisms 10 on the left and right. A total of three lifting and bending mechanisms 10 and bending heads 11 are provided on the same side; and the lifting and bending mechanisms 10 all move correspondingly synchronously.

[0023] There are three sets of double - lead screw motors 14 in the pressing - down mechanism 12. On the screw - rod seats 8 on both sides of each set of double - lead screw motors 14, bending pressing blocks 15 are installed. The three bending pressing blocks 15 on the same side are set as a whole, and the three sets of double - lead screw motors 14 move synchronously, driving the bending pressing blocks 15 of the overall structures on both sides to move inwards or outwards synchronously.

[0024] Correspondingly, the bending pressing block 15 extends outwards at the bottom of the screw - rod seat 8, and an arc - shaped bending surface 16 is also provided at the outer end face of the bending pressing block 15.

[0025] A number of vertically - arranged rotating motors 17 are also installed on both sides of the feeding table 1. The main shafts of the rotating motors 17 on both sides extend upwards, and rotating rollers 18 are correspondingly installed at the shaft ends. The rotating motors 17 on both sides are arranged in parallel, the rotating motors 17 on the same side are evenly spaced, and the distance between the rotating motors 17 on both sides is set to be adapted to the width of the plate body 21 to be bent. When the plate body 21 is placed at the feeding end 2 of the feeding table 1, the plate body 21 is correspondingly clamped by the rotating rollers 18 on both sides and moves on the feeding table 1 under the action of the rotating rollers 18 on both sides, and finally moves to the position of the discharging end 3.

[0026] The rotating motors 17 are all set as stepper structures, and a receiving frame 19 is also installed at the position of the discharging end 3 of the feeding table 1; a layer of soft pads 20 is also installed on the rotating rollers 18, and the middle plate body 21 is correspondingly clamped through the soft pads 20.

[0027] The specific working process and working principle of the present invention are as follows: As Figure 4 shown, in the present invention, the plate body is placed at the feeding - end position of the feeding table. The rotating motors on both sides rotate correspondingly driven by the rotating rollers. The distance between the rotating rollers on both sides is adapted to the width of the plate body, and a layer of soft pads is also provided on the rotating rollers. The plate body is clamped between the rotating rollers and is driven by the rotating rollers to move towards the discharging end. And the rotating motors are set in a stepper mode, and the plate body is fed step by step to the position of the feeding end.

[0028] At the feeding - end position, the rotating motor will correspondingly stop. At this time, first, the pressing - down mechanism at the upper end drives the pressing - down seat to move downwards, pressing the bending pressing blocks on both sides against the plate body below, thereby fixing the plate body on the feeding table. Then, the lifting and bending mechanism at the lower end is started, so that the bending head at the upper end of the lifting and bending mechanism moves upwards, thus jacking up the two ends of the plate body upwards on both sides to achieve bending. As Figure 3 shown, the bending pressing block itself is provided with an arc - shaped bending surface at the outer end. When the plate body is jacked up by the bending head below, the two sides of the plate body are naturally jacked up, thereby realizing double - way bending work on both sides simultaneously and improving work efficiency.

[0029] After the bending is completed, the pressing mechanism is first lifted upward to leave the plate body, and the subsequent plate bodies on the feeding table will still move forward under the driving action of the rotating rollers on both sides, so as to push the plate body that has been bent at the discharging end forward, and then fall into the receiving frame at the front end to complete the discharging work of the bent plate body.

[0030] In the above process, both the position of the bending pressing block at the upper end and the position of the lifting and bending mechanism at the lower end can be adjusted. Both can be adjusted bidirectionally through the combined structure of the double-headed screw motor set. Then, it can be adjusted according to the specific width of the plate body to be bent. First, the positions of the two bending pressing blocks at the upper end can be adjusted according to the bending width. After the positions of the bending pressing blocks are adjusted, then adjust the positions of the lifting and bending mechanisms on both sides below, so that the bending heads on both sides are located outside the bending pressing blocks on both sides. At this time, the bending heads can be lifted upward through the lifting and bending mechanisms to achieve bending. Therefore, the overall bending width can be adjusted, and the bending work on both sides of the plate body can also be completed.

[0031] In addition, in the present invention, for the overall bending effect and the stability of the structure, three groups of double-headed screw components are provided at both the upper and lower ends. The bending pressing blocks at the upper end are set as a whole, and the bending heads at the lower end are set as rolling bending wheels, and they all move synchronously, and the structure is more reasonable.

[0032] The above specific implementation manner is only a preferred embodiment of the present invention, and is not used to limit the implementation and the scope of the claims of the present invention. All equivalent changes and modifications made according to the content of the patent protection scope of the present invention application should be included in the scope of the present invention patent application.
