Description

Technical Field

[0001] The present invention relates to the technical field of profile bending, and specifically to a bending device for the edge-wrapping profile of a motorhome skylight. Background Art

[0002] The frame of a motorhome skylight is in a square shape and is generally made of profiles processed by a bending machine. The corners of the skylight frame have an arc transition. Therefore, when bending the profiles, the profiles need to be bent four times so that the two ends of the profiles are butted at the side of the frame, and the butted parts of the two ends of the profiles are strengthened by welding.

[0003] A Chinese patent with an application date of February 4, 2020 and a publication number of CN212350154U discloses a convenient bending device for the edge-wrapping profile of a motorhome skylight, which includes a bracket and a positioning frame fixed at the upper end of the bracket. There are eight first clamping pliers arranged around the positioning frame, and the eight first clamping pliers are arranged in groups of two at the corners of the positioning frame. Flanging assemblies are provided at the four corners of the positioning frame, and second clamping pliers are provided at the middle positions of the front and rear ends of the positioning frame. This utility model uses eight first clamping pliers and two second clamping pliers to press and position the edge-wrapping profile sleeved on the positioning frame, and then uses the flanging assemblies to rotate and squeeze the edge-wrapping profile around the positioning frame to complete the convenient flanging of the edge-wrapping profile, improve the flanging quality and efficiency, and have high processing accuracy.

[0004] In this technical solution, it is necessary to manually adjust structures such as clamping pliers to clamp, position, bend and other operations on the profiles. Since motorhome skylights need to be mass-produced, the efficiency of manually bending profiles is low, so further improvement can be made. Summary of the Invention

[0017] (III) Beneficial effects

[0018] Compared with the prior art, the present invention provides a bending device for the edge wrapping profile of a motorhome skylight, which has the following beneficial effects:

[0019] 1. The bending device for the edge profile of the skylight of the RV can drive two first bending components to deflect through the rotation driving part on the front side of the suspension hanger, so that the two first rollers rotate in opposite directions. During the deflection of the first rotating arm, the first pushing column fits on the front side of the profile and pushes the profile to deflect backward around the circumferential surface of the first roller until the profile fits on the side of the side lining plate. Then, the rotation driving part on the rear side of the suspension hanger drives the two second bending components to deflect, so that the second rotating arm deflects. During the sliding of the sliding bead along the arched groove, the collar, the connecting plate and the second pushing column rise, so that the top end of the second pushing column is higher than the side lining plate, avoiding the bottom end of the second pushing column from colliding with the side lining plate or the profile. Then, the sliding bead slides along the arc-shaped groove, keeping the second pushing column at a lower position. During this process, the second pushing column fits on the side of the profile and pushes the profile to deflect around the second roller until the profile fits on the rear side of the rear lining plate. Thus, the profile can be automatically bent four times, with high automation and high processing efficiency.

[0020] 2. The bending device for the edge profile of the skylight of the RV, before bending the profile, drives one of the turntables to rotate through the second motor, and drives multiple turntables to rotate synchronously under the transmission action of the third sprocket and the second endless chain. During the rotation of the turntable, the pressing rod fits on the top of the profile in turn, and the extrusion force between the pressing rod and the profile is ensured through the elasticity of the second spring. Cooperating with the rotation of the turntable, the profile moves from right to left until the left end of the profile fits on the left baffle. After bending the profile, the output end of the cylinder extends, driving the arched plate to move downward, making the clamping plate move forward and no longer clamping the profile. And the arched plate fits on the top of the profile and moves downward, pushing the profile through the annular unloading groove and into the discharge hopper. Thus, the purpose of automatically loading and unloading the profile, ensuring the bending rhythm of the profile and ensuring the processing efficiency of the profile is achieved.

[0040] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0041] Please refer to Figures 1-4 , A bending device for the edge profile of a motorhome skylight, comprising a processing table 100. A suspension bracket 200 is fixedly installed on the top of the processing table 100. The top of the processing table 100 is in a square shape. A support plate 300 is arranged at the center of the top of the processing table 100. An annular material return groove is formed between the edge of the support plate 300 and the processing table 100. Two first bending assemblies 400 are rotatably connected to both corners on the front side of the support plate 300, and two second bending assemblies 500 are rotatably connected to both corners on the rear side of the support plate 300. Rotating driving members 600 are arranged between the tops of the two first bending assemblies 400 and between the tops of the two second bending assemblies 500. A clamping assembly 700 is arranged on the front side of the top of the processing table 100. A material return assembly 800 is arranged through the center of the suspension bracket 200. A feeding assembly 900 is arranged on the right side of the processing table 100.

[0042] Please refer to Figures 2-3, a front baffle 101 is fixedly installed on the top of the processing table 100. The front baffle 101 is located on the front side of the annular material return groove. A left baffle 102 is fixedly installed on the rear side of the left end of the front baffle 101. The left baffle 102 is used to block and limit the profile. A first avoidance groove 103 is formed through the middle of the front baffle 101. The first avoidance groove 103 is used to avoid the clamping assembly 700. Two second avoidance grooves 104 are formed through the front baffle 101. The two second avoidance grooves 104 are respectively located on the left and right sides of the first avoidance groove 103. A discharge hopper 105 is fixedly installed on the top wall of the processing table 100. The discharge hopper 105 is located below the annular material return groove. After the bending of the profile is completed, under the extrusion of the material return assembly 800, the profile passes through the annular material return groove and enters the discharge hopper 105, and then the discharge hopper 105 guides and transfers the profile after the bending is completed.

[0043] Please refer to Figures 2-3 , a suspension rod 301 is fixedly installed between the center of the top of the support plate 300 and the suspension bracket 200. The support plate 300 is suspended at the center of the processing table 100 through the suspension rod 301. A front lining plate 302 is fixedly installed on the front side edge of the top of the support plate 300. Side lining plates 303 are fixedly installed on the left and right side edges of the top of the support plate 300. A rear lining plate 304 is fixedly installed on the rear side edge of the top of the support plate 300. The profile is supported from the inside by the front lining plate 302, the side lining plates 303 and the rear lining plate 304. Two third avoidance grooves 305 are formed through the rear lining plate 304. The two third avoidance grooves 305 are distributed left and right. The third avoidance groove 305 is used to avoid the second bending assembly 500.

[0044] Please refer to Figure 4 , each group of first bending assemblies 400 includes a first roller 401. A first limiting ring 402 is fixedly installed on the circumferential surface of the first roller 401. The first limiting ring 402 is attached to the top of the profile. A first rotating arm 403 is fixedly installed on the top of the first roller 401. A first pushing column 404 is fixedly installed at the bottom of the end of the first rotating arm 403 away from the first roller 401. The profile is conveyed from right to left through the feeding assembly 900. The profile moves between the front baffle 101 and the front lining plate 302, and the left baffle 102 is used to block and limit the profile. By rotating the driving member 600 to drive the two first rollers 401 to rotate in opposite directions, the first pushing column 404 passes through the second avoidance groove 104 and fits against the front side of the profile, and deflects the left and right halves of the profile backward, so that the profile is bent at the position of the two first rollers 401 until the profile fits against the side lining plate 303.

[0045] Please refer to Figure 5, each second bending component 500 includes a second roller 501. A second limiting ring 502 is fixedly installed on the circumferential surface of the second roller 501, and the second limiting ring 502 is attached to the top of the profile. A second rotating arm 503 is fixedly installed on the top of the second roller 501. A second push column 504 is slidably connected through one end of the second rotating arm 503 away from the second roller 501. By rotating the driving member 600 to drive the two second rollers 501 to rotate in opposite directions, the second push column 504 is attached to one side of the profile away from the side lining plate 303, and the profile is pushed to deflect towards the rear lining plate 304, and the profile is bent again at the position of the second roller 501.

[0046] A support pipe 505 is arranged directly above the second roller 501. The support pipe 505 is fixedly installed at the bottom of the suspension bracket 200. An annular groove is formed on the outer wall of the support pipe 505, and the annular groove is composed of an arc-shaped groove 506 and an arch-shaped groove 507. The middle part of the arch-shaped groove 507 is horizontal, and both sides are inclined; a collar 508 is sleeved outside the support pipe 505. A sliding bead 509 is fixedly installed on the inner wall of the collar 508, and the sliding bead 509 is slidably connected in the annular groove. A connecting plate 510 is fixedly installed on the outer wall of the collar 508. One end of the connecting plate 510 away from the collar 508 is fixedly installed on the top of the second push column 504. A vertical rod 511 is fixedly installed on the top of the second rotating arm 503, and the connecting plate 510 is slidably connected to the connecting plate 510.

[0047] During the rotation of the second roller 501, through the connection of the second push column 504, the connecting plate 510 and the vertical rod 511, the collar 508 rotates synchronously with the second roller 501, and the sliding bead 509 slides in the annular groove. When the sliding bead 509 slides along the arc-shaped groove 506, the second push column 504 is in a lower position and can be attached to the surface of the profile and push the profile to bend. When the sliding bead 509 slides along the arch-shaped groove 507, the second push column 504 is in a higher position to avoid the second push column 504 from colliding with the side lining plate 303 and the profile.

[0048] Please refer to Figure 6 , each rotating driving member 600 includes a first motor 601. The output end of the first motor 601 is connected to a speed reducer 602.

A second gear 605 is meshed on the left side of the first gear 604, and the rotation directions of the first gear 604 and the second gear 605 are opposite.

[0049] A first sprocket 606 is coaxially fixed on the upper side of the second gear 605, and the rotation directions of the second gear 605 and the first sprocket 606 are the same. A second sprocket 607 is arranged on the left side of the first sprocket 606. The first sprocket 606 and the second sprocket 607 are connected by an annular chain 608. A driven shaft 609 is fixedly installed at the center of the bottom of the second sprocket 607. Thus, the rotation direction of the second sprocket 607 is the same as that of the first sprocket 606. Thus, the rotation directions of the driving shaft 603 and the driven shaft 609 are opposite.

[0050] One set of drive shafts 603 and follower shafts 609 are respectively fixedly installed at the central tops of two first rollers 401, and the other set of drive shafts 603 and follower shafts 609 are respectively fixedly installed at the central tops of two second rollers 501. Thus, the rotation directions of the two first rollers 401 are opposite, and the rotation directions of the two second rollers 501 are opposite. Specifically, the drive shaft 603 passes through the center of the support pipe 505.

[0051] Please refer to Figures 7-8 , the clamping assembly 700 includes a slide rail 701 fixedly installed on the top of the processing table 100. The slide rail 701 is located at the front side of the middle part of the front baffle 101. A slide seat 702 is slidably connected in the slide rail 701. Two slide bars 703 are slidably connected through the slide seat 702. A clamping plate 704 is fixedly installed at the rear ends of the two slide bars 703.

The two ends of the first spring 705 are respectively fixedly installed on the slide seat 702 and the clamping plate 704. Due to the elasticity of the first spring 705, the clamping plate 704 has a tendency to move away from the slide seat 702. When the slide seat 702 moves backward, the clamping plate 704 passes through the first avoidance groove 103. The clamping plate 704 fits on the front side and the top of the profile, and the front lining plate 302 fits on the rear side of the profile, so as to stably clamp and fix the middle part of the profile.

[0052] Please refer to Figures 7-8 , a U-shaped pipe 706 is arranged on the front side of the slide seat 702. The U-shaped pipe 706 is filled with hydraulic oil. The U-shaped pipe 706 is fixedly installed between the processing table 100 and the suspension bracket 200. A first piston 707 is slidably connected in one end at the bottom of the U-shaped pipe 706. The rear end of the first piston 707 is fixedly installed on the slide seat 702. A second piston 708 is slidably connected in one end at the top of the U-shaped pipe 706. The rear end of the second piston 708 is hinged with a pull rod 709. The rear end of the pull rod 709 is hinged on the unloading assembly 800. By pulling the rear end of the pull rod 709 through the unloading assembly 800, the second piston 708 is driven to slide in the U-shaped pipe 706. When the second piston 708 slides forward, the first piston 707 is driven to slide backward along the U-shaped pipe 706, so as to drive the slide seat 702 to move backward along the slide rail 701, and make the clamping plate 704 fit on the profile.

[0053] Please refer to Figures 7-8, the material discharging assembly 800 includes a cylinder 801 fixedly installed at the center of the top of the suspension bracket 200. The output end of the cylinder 801 penetrates through the suspension bracket 200. An arched plate 802 is fixedly installed at the output end of the cylinder 801. Both ends of the arched plate 802 are located directly above the annular material discharging groove. Two guide rods 803 are fixedly installed at the top of the arched plate 802. The guide rods 803 penetrate and are slidably connected to the suspension bracket 200. The guide rods 803 are used to guide the moving path of the arched plate 802. The rear end of the pull rod 709 is hinged to the front side of the arched plate 802. By extending the output end of the cylinder 801, the arched plate 802 is driven to move downward, pushing the bent profile downward and enabling the bent profile to pass through the annular material discharging groove and enter the discharge hopper 105.

[0054] Please refer to Figure 9 , the feeding assembly 900 includes a support frame 901 fixedly installed on the right side of the processing table 100. Two baffles 902 are fixedly installed at the top of the support frame 901. A feeding channel is formed between the two baffles 902. The feeding channel is used to guide the profile.

A third sprocket 907 is fixedly installed at the center of the front side of each turntable 903. The third sprockets 907 are connected by an annular chain 908. A second motor 909 is fixedly installed at the center of one of the turntables 903. Through the transmission of the third sprockets 907 and the annular chain 908, multiple turntables 903 rotate synchronously. During the rotation of the turntable 903, the pressure rods 905 alternately fit on the top of the profile, and through the elasticity of the second spring 906, the extrusion force between the pressure rods 905 and the profile is ensured, enabling the profile to be stably conveyed to the left.

[0055] During use, one of the turntables 903 is driven to rotate by the second motor 909, and with the transmission of the third sprockets 907 and the annular chain 908, multiple turntables 903 are driven to rotate synchronously; during the rotation of the turntable 903, the pressure rods 905 sequentially fit on the top of the profile, and through the elasticity of the second spring 906, the extrusion force between the pressure rods 905 and the profile is ensured, and with the rotation of the turntable 903, the profile moves from right to left until the left end of the profile fits against the left baffle 102;

[0056] By contracting the output end of the cylinder 801, the arched plate 802 is driven to move upward, and through the connection of the pull rod 709, the piston 708 is driven to move forward, causing the piston 707 to push the slide seat 702 backward, driving the clamping plate 704 to pass through the first avoidance groove 103 and fit against the profile, so that the clamping plate 704 and the front lining plate 302 cooperate to clamp and fix the middle part of the profile;

[0057] First, drive the deflection of two first bending assemblies 400 through the rotation driving member 600 on the front side of the suspension bracket 200. Specifically, the first motor 601 and the speed reducer 602 drive the drive shaft 603 to rotate, driving the first gear 604 to rotate. With the meshing effect of the first gear 604 and the second gear 605, drive the second gear 605 and the first sprocket 606 to rotate together. Then, through the transmission of the first sprocket 606, the second sprocket 607 and the first endless chain 608, drive the driven shaft 609 to rotate, so that the drive shaft 603 and the driven shaft 609 rotate synchronously and in opposite directions, causing the two first rollers 401 to rotate in opposite directions; during the deflection of the first rotating arm 403, the first push column 404 fits against the front side of the profile and pushes the profile to deflect backward around the circumference of the first roller 401 until the profile fits against the side of the side lining plate 303;

[0058] Then, drive the deflection of two second bending assemblies 500 through the rotation driving member 600 on the rear side of the suspension bracket 200, so as to deflect the second rotating arm 503. During the sliding of the sliding bead 509 along the arched groove 507, the collar 508, the connecting plate 510 and the second push column 504 rise, making the top of the second push column 504 higher than the side lining plate 303 to prevent the bottom end of the second push column 504 from colliding with the side lining plate 303 or the profile. Then, the sliding bead 509 slides along the arc groove 506, keeping the second push column 504 in a lower position. During this process, the second push column 504 fits against the side of the profile and pushes the profile to deflect around the second roller 501 until the profile fits against the rear side of the rear lining plate 304;

[0059] Finally, extend the output end of the cylinder 801 to drive the arched plate 802 to move downward, causing the clamping plate 704 to move forward and no longer clamp the profile; and make the arched plate 802 fit against the top of the profile and move downward, pushing the profile through the annular discharging groove and into the discharging hopper 105.

The scope of the present invention is defined by the appended claims and their equivalents.
