Description

Technical Field

[0001] The invention relates to the technical field of door panel processing equipment, and in particular to a bending equipment used for door panel processing. Background Art

[0002] In the field of door panel processing, the bending process is the key link in shaping the specific shape of the door panel to meet the diverse product design needs. Traditional door panel bending equipment mostly relies on pressing plates to fix the door panel during the bending process.

[0003] With the development of the door panel manufacturing industry, the market demand for door panel specifications is becoming increasingly diversified, and the thickness difference of door panels is becoming more and more significant. The existing bending equipment of this type has gradually exposed obvious defects in practical applications. Most of its clamping devices use fixed structure pressing plates. When facing door panels of different thicknesses, when thinner door panels are clamped with conventional pressing plates, the contact area is too large, and it is easy to leave too many indentations on the surface of the door panels, affecting the appearance quality of the door panels. Additional polishing and other processes are required later, increasing production costs and working hours. For thicker door panels, if the pressing plate cannot fit fully, the contact area is too small, and it cannot provide sufficient clamping force, the door panels are prone to loosening and displacement during the bending process, which greatly reduces the bending accuracy and increases the scrap rate.

When the door panel is thin, the piston disc 1, slide rod 1 and lifting strip and other components in the liquid storage cylinder work together, and the liquid transmits pressure to the fixed cylinder through the liquid inlet pipe, pushing the piston disc 2 and slide rod 2 to move, and then driving the extrusion strip to extrude the arc block 1, so that the pressure plate 1 is pressed down with the cooperation of the spring 3 to avoid indentations caused by large-area contact, ensuring the perfect appearance of the door panel. When the door panel is thicker, the entire clamping mechanism can be linked in reverse to fully stretch each pressure plate, increase the contact area, provide sufficiently strong clamping force, and ensure that the door panel does not move during the bending process, which greatly improves the bending accuracy and effectively reduces the scrap rate.

[0015] 2. The extrusion block, slider and vertical bar in the auxiliary mechanism cooperate to provide lateral support for the clamping mechanism. When bending large door panels or door panels with harder materials and large reaction force, the slider slides along the vertical bar to ensure that each pressure plate does not deviate in the horizontal direction. The extrusion block further strengthens the structural rigidity, so that the clamping force is evenly distributed, effectively preventing the door panel from bending due to uneven force, and ensuring the consistency of processing accuracy. When the thickness of the door panel changes and causes the clamping mechanism to adjust, the gas pressure in the airbag changes, pushing the moving block to move, driving the locking rod to slide in the slider and the rectangular shell. When the locking rod is stuck in the locking hole of the vertical bar, precise locking is achieved, which not only ensures that the clamping mechanism is stable and motionless in the working state, but also can be quickly unlocked and adjusted when the thickness of the door panel switches. The operation is convenient and efficient, providing a strong guarantee for continuous door panel processing. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Furthermore, the adjusting part includes a fixed frame 671 fixed on the clamping frame 5, a fixed cylinder 672 is fixed on the side of the fixed frame 671, the end of the liquid inlet pipe 66 away from the liquid storage cylinder 61 is connected to the fixed cylinder 672, a piston disk 673 is sliding in the fixed cylinder 672, a slide rod 674 is fixed on the piston disk 673, the slide rod 674 is slidably connected to the fixed cylinder 672, a spring 675 is sleeved on the outer surface of the slide rod 674, both ends of the spring 675 are respectively fixedly connected to the piston disk 673 and the fixed cylinder 672, a movable frame 676 is fixed on the end of the slide rod 674 away from the piston disk 673, and an extrusion strip 677 is fixed on the side of the movable frame 676 away from the slide rod 674.

[0022] Furthermore, a clamping part 1 is provided on the clamping frame 5, and the clamping part 1 includes a horizontal plate 1681 fixed on the clamping frame 5, an extrusion rod 1682 is slid on the horizontal plate 1681, a pressure plate 1683 is fixed to the bottom end of the extrusion rod 1682, an arc block 1684 is fixed to the top end of the extrusion rod 1682, the arc block 1684 and the extrusion bar 677 are in the same horizontal line, and a spring 3 685 is sleeved on the outer surface of the extrusion rod 1682, and the two ends of the spring 3 685 are respectively fixedly connected to the horizontal plate 1681 and the arc block 1684.

[0023] When in use, place the door panel on the processing table 1, drive the clamping frame 5 downward by the cylinder 4 to fix the door panel, and drive the bending part 2 to rotate by the motor installed on the processing table 1 to bend the door panel. This is the existing technology, so it will not be described in detail here.

[0024] Considering that in the prior art, most of the clamping devices use a fixed structure of the clamping plate. When facing door panels of different thicknesses, when thinner door panels are clamped with conventional clamping plates, such as when facing some decorative door panels with a thickness of only 3-5 mm, the contact area is too large, and it is easy to leave too many indentations on the surface of the door panel, affecting the appearance quality of the door panel. Additional polishing and other processes are required later, which increases production costs and working hours. For thicker door panels, such as thick fireproof door panels with a thickness of 40-50 mm, if the clamping plate cannot be fully fitted, the contact area is too small and it cannot provide sufficient clamping force, resulting in the door panel being prone to loosening and displacement during the bending process, which greatly reduces the bending accuracy and increases the scrap rate. The following improvements are now made: In the initial state, the pressing frame 5 is driven downward by the cylinder 4 to fix the door panel. When the pressing frame 5 moves downward, it also drives the fixing cylinder 672 and the fixing frame 671 to move downward together. When the door panel moves to the bending part 2 on the processing table 1, it will first contact the lifting strip 64. Since one side of the lifting strip 64 is inclined, when the door panel contacts the lifting strip 64, it will drive the lifting strip 64 to move upward. Since the slide bar 1 63 slides in the liquid storage cylinder 61, the lifting strip 64 will be squeezed and drive the piston plate 1 62 and the slide bar 1 63 in the liquid storage cylinder. 61 slides upward, squeezes the liquid in the liquid storage cylinder 61, and allows the liquid to enter the fixed cylinder 672 through the liquid inlet pipe 66. After being squeezed by the liquid, the piston plate 673 moves in the fixed cylinder 672 toward the fixed frame 671, thereby driving the sliding rod 674 and the moving frame 676 to move together. The moving frame 676 drives the squeezing bar 677 to move together, squeezing the spring 675. Due to the different thicknesses of the door panels, the lifting bar 64 will move up to different distances, so the moving frame 676 will also move to different distances.

[0025] When the thickness of the door panel to be processed is between 3 and 5 mm, the moving distance of the extrusion strip 677 is short, and it can only move to contact the arc block 684. Since the extrusion rod 682 is slidably connected to the cross plate 681, when the extrusion strip 677 contacts the arc block 684, it will drive the arc block 684 and the extrusion rod 682 to move downward, and squeeze the spring 3 685. The extrusion rod 682 drives the pressure plate 683 to move downward to fix the door panel. Therefore, for a thinner door panel, it can be fixed by the cooperation between the clamping frame 5 and the pressure plate 683. While providing sufficient clamping force, it can also avoid excessive contact area, leaving too many indentations on the surface of the door panel, and affecting the appearance quality of the door panel.

[0026] Example 2, refer to Figure 1-Figure 7A bending device for door panel processing includes a processing table 1, a rotatable bending member 2 is arranged on the processing table 1, the rotation of the bending member 2 is driven by a motor installed on the processing table 1, a mounting frame 3 is connected to the processing table 1, a cylinder 4 is installed on the mounting frame 3, a pressing frame 5 is fixed to the bottom end of the extension rod of the cylinder 4, and also includes: A pressing mechanism disposed on the mounting frame 3, the pressing mechanism being used to adjust the contact area between the pressing plate and the door panel according to the thickness of the door panel; An auxiliary mechanism installed on the clamping mechanism, the auxiliary mechanism is used to make the clamping mechanism more stable.

[0027] Furthermore, a clamping part 2 is provided on the clamping frame 5, and the clamping part 2 includes a horizontal plate 2 691 fixed on the clamping frame 5, and the horizontal plate 2 691 is located on the side of the horizontal plate 1 681 away from the extrusion bar 677, and an extrusion rod 2 692 is slid on the horizontal plate 2 691, and a pressure plate 2 693 is fixed to the bottom end of the extrusion rod 2 692, and an arc block 2 694 is fixed to the top end of the extrusion rod 2 692, and a spring 4 695 is sleeved on the outer surface of the extrusion rod 2 692, and both ends of the spring 4 695 are respectively fixedly connected to the horizontal plate 2 691 and the arc block 2 694, and the volume of the pressure plate 2 693 is larger than that of the pressure plate 1 683.

[0028] Furthermore, a clamping part three is provided on the clamping frame 5, and the clamping part three includes a horizontal plate three 601 fixed on the clamping frame 5, and the horizontal plate three 601 is located on the side of the arc block two 694 away from the arc block one 684, and an extrusion rod three 602 is slid on the horizontal plate three 601, and a pressure plate three 603 is fixed to the bottom end of the extrusion rod three 602, and an arc block three 604 is fixed to the top end of the extrusion rod three 602, and a spring five 605 is sleeved on the outer surface of the extrusion rod three 602, and the two ends of the spring five 605 are respectively fixedly connected to the horizontal plate three 601 and the arc block three 604, and the volume of the pressure plate three 603 is larger than that of the pressure plate two 693.

[0029] When the thickness of the processed door panel reaches 20 mm, the moving distance of the lifting strip 64 and the extrusion strip 677 increases, and the extrusion strip 677 will move to the arc block 2 694. Since the shapes of the arc block 1 684 and the arc block 2 694 are both arc-shaped, when the extrusion strip 677 moves to the arc block 2 694, it will not affect the clamping effect of the pressure plate 1 683. When the extrusion strip 677 contacts the arc block 2 694, it will drive the arc block 2 694 and the extrusion rod 2 692 to move downward, and the extrusion rod 2 692 drives the pressure plate 2 693 to move downward, and the spring 4 695 is squeezed. The pressure plate is clamped by the cooperation between the clamping frame 5, the pressure plate 1 683 and the pressure plate 2 693, so that the clamping area of ​​the door panel can be increased, thereby appropriately increasing the clamping force.

[0030] When the thickness of the processed door panel is between 40-50 mm, the extrusion strip 677 will move to the position of the arc block three 604 and contact the arc block three 604, thereby driving the extrusion rod three 602 and the pressure plate three 603 to move downward, squeezing the spring five 605, and the pressure plate is clamped through the cooperation between the pressure plate three 603, the clamping frame 5, the pressure plate one 683 and the pressure plate two 693.

[0031] A further advantage of adopting the above method is that the contact area between the pressure plate and the door panel can be flexibly adjusted according to the actual thickness of the door panel. When the door panel is thin, indentations caused by large-area contact can be avoided to ensure that the appearance of the door panel is flawless. When the door panel is thicker, the entire clamping mechanism can be linked in reverse to allow each pressure plate to fully stretch, increase the contact area, provide sufficiently strong clamping force, and ensure that the door panel does not move during the bending process, thereby greatly improving the bending accuracy and effectively reducing the scrap rate.

[0032] Example 3, refer to Figure 1-Figure 7 A bending device for door panel processing includes a processing table 1, a rotatable bending member 2 is arranged on the processing table 1, the rotation of the bending member 2 is driven by a motor installed on the processing table 1, a mounting frame 3 is connected to the processing table 1, a cylinder 4 is installed on the mounting frame 3, a pressing frame 5 is fixed to the bottom end of the extension rod of the cylinder 4, and also includes: A pressing mechanism disposed on the mounting frame 3, the pressing mechanism being used to adjust the contact area between the pressing plate and the door panel according to the thickness of the door panel; An auxiliary mechanism installed on the clamping mechanism, the auxiliary mechanism is used to make the clamping mechanism more stable.

[0033] Furthermore, the auxiliary mechanism includes an extrusion block 70 fixed on the arc block 2 694 and the arc block 3 604, a slider 71 is fixed on the arc block 1 684 and the arc block 2 694, a vertical bar 72 is fixed on the top of the horizontal plate 1 681 and the horizontal plate 2 691, the slider 71 slides on the outer surface of the vertical bar 72, and a rectangular shell 73 is fixed on the outer surface of the slider 71.

[0034] Furthermore, the auxiliary mechanism also includes an airbag 74 fixed in the rectangular shell 73, a moving block 75 is fixed on the airbag 74, the moving block 75 slides in the rectangular shell 73, a locking rod 76 is fixed on the side of the moving block 75 away from the airbag 74, the locking rod 76 is slidably connected to the slider 71 and the rectangular shell 73, a spring 6 77 is sleeved on the outer surface of the locking rod 76, and the two ends of the spring 6 77 are respectively fixedly connected to the rectangular shell 73 and the moving block 75.

[0035] Furthermore, the auxiliary mechanism also includes an air cushion 79 fixed on the horizontal plate three 601 and the horizontal plate two 691. The outer surface of the air cushion 79 is connected to the air intake pipe 710. The end of the air intake pipe 710 away from the air cushion 79 is connected to the airbag 74. The vertical bars 72 are provided with locking holes 78, and the locking rod 76 is slidably connected to the locking hole 78.

[0036] When the extrusion bar 677 moves to the arc block 694, the extrusion bar 677 will move the arc block 684 to the lowest position, and the arc block 684 will drive the slider 71 to slide downward to the lowest position on the outer surface of the vertical bar 72. At this time, the locking rod 76 corresponds to the position of the locking hole 78, and the arc block 694 is squeezed by the extrusion bar 677, and the arc block 694 will gradually drive the extrusion block 70 to move downward. When it drops to a certain height, it will squeeze the air cushion 79, so that the gas in the air cushion 79 enters the air bag 74 through the air inlet pipe 710, so that the air bag 74 expands. Since the locking rod 76 is slidably connected to the rectangular shell 73, when the air bag 74 expands, it will push the moving block 71 to move downward. The movable block 75 and the locking rod 76 move toward the locking hole 78. When the air cushion 79 moves to the lowest point, the locking rod 76 will be stuck in the locking hole 78 to lock the slider 71 and the vertical bar 72. In this way, when a thicker door panel is bent, the pressure will be on the pressure plate 1 683. Similarly, when the extrusion bar 677 moves to the arc block 3 604, the arc block 2 694 and the vertical bar 72 on the cross plate 2 691 can be locked. When bending a thicker door panel, the pressure will be on the pressure plate 1 683 and the pressure plate 2 693. This not only ensures that the clamping mechanism is stable and motionless in the working state, but also can be quickly unlocked and adjusted when the thickness of the door panel is switched. The operation is convenient and efficient, providing a strong guarantee for continuous door panel processing.
