Description

Technical Field

[0001] This invention relates to the field of edge banding and bending equipment technology, specifically a cabinet side panel edge banding and bending machine. Background Technology

[0002] Edge banding is a crucial step in the production of server rack panels, enhancing the overall quality and durability of the rack. It effectively protects the rack's edges, preventing wear and deformation, thus extending its lifespan.

[0003] Since server rack side panels are often made of thin sheet metal, mechanical edge banding is commonly used during the edge banding process. This involves using mechanical devices to press or weld the edges of the metal sheets to achieve the desired edge banding effect. Existing edge banding bending devices mostly use mechanical structures to push the edge of the sheet metal, then fix and fold it, essentially rolling the edge 180 degrees in one station. Because server rack side panels are often thin sheets, this edge banding method leads to stress accumulation at the edge of the sheet metal, resulting in significant deformation and distortion. This causes uneven thickness and inconsistent edge banding shape, affecting the overall quality of the sheet metal processing. Summary of the Invention

[0004] The purpose of this invention is to provide a cabinet side panel edge sealing bending machine to solve the problem mentioned in the background art that the existing edge sealing method leads to stress accumulation at the edge of the board and causes large deformation and distortion, which affects the processing quality of the board.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A cabinet side panel edge banding bending machine includes a workbench. A bending mounting frame is fixedly connected to one side of the top of the workbench, and a positioning mounting frame is fixedly connected to the other side of the top of the workbench. A feeding roller is rotatably connected to one end of the inner wall of each positioning mounting frame. A through groove for the edge of a panel to pass through is opened on the side of the bending mounting frame and the positioning mounting frame that are close to each other. An installation groove is opened in the middle of the workbench, and a panel conveyor belt is rotatably installed on the inner wall of the installation groove.

[0007] The inner wall of the bending mounting frame is provided with a flanging assembly, a folding assembly, and a pressing assembly in sequence along the moving direction of the sheet conveyor belt. The flanging assembly is used to fold the edge of the sheet up, the folding assembly is used to fold the folded edge down, and the pressing assembly is used to press the folded edge of the sheet together. The positioning mounting frame is provided with two positioning assemblies inside, which are respectively positioned to correspond to the flanging assembly and the folding assembly.

[0008] As a further aspect of the present invention: the flanging assembly includes an active pressing unit for pressing and positioning the edge of the sheet metal and a lifting and folding unit for pushing the edge of the sheet metal to fold.

[0009] The movable pressing unit includes a connecting frame, the top of which is fixedly connected to the inner wall of the bending mounting frame, a limiting rod fixedly connected to the middle of the connecting frame, a movable frame slidably connected to the middle of the limiting rod, several pushing rods fixedly connected to the bottom of the movable frame, a pressing roller rotatably connected to the bottom of the pushing rods, a return spring sleeved on the outer wall of the limiting rod, and several displacement sensors embedded on the inner wall of the connecting frame near the positioning mounting frame.

[0010] The lifting and folding unit includes a receiving groove, and a push plate is rotatably connected to the inner wall of the receiving groove. A folding push rod is provided below the push plate, and the output end of the folding push rod is slidably connected to the bottom of the push plate.

[0011] As a further aspect of the present invention: the folding assembly includes a pushing unit and a folding pushing unit. The folding pushing unit includes a horizontal pushing cover plate, a horizontal pushing guide rail is fixedly installed on the inner wall of the horizontal pushing cover plate, and a horizontal pushing folding plate is slidably installed on the inner wall of the horizontal pushing guide rail. The pushing unit includes a horizontal push rod, a roller frame is fixedly connected to the output end of the horizontal push rod, and a pressing roller is rotatably installed on the inner wall of the roller frame. The height of the pressing roller is higher than the height of the horizontal pushing folding plate, and the distance between the two is slightly greater than the thickness of the plate.

[0012] As a further embodiment of the present invention: the positioning component includes a lifting push rod, the lifting push rod includes a lifting frame, a side positioning unit is fixedly installed at one end of the lifting frame, the side positioning unit includes a support plate, a plurality of side guide wheels are rotatably connected to the middle of the support plate, a limit push rod is fixedly connected to one end of the support plate, and an end baffle is fixedly connected to the output end of the limit push rod; an adjusting guide rail is fixedly installed at the other end of the lifting frame, and a movable positioning unit is slidably installed on the inner wall of the adjusting guide rail, the movable positioning unit having the same structure as the side positioning unit.

[0013] As a further aspect of the present invention: the pressing assembly includes a pressing push rod, the output end of which is fixedly connected to a pressing frame, and a pressing disc is rotatably mounted on the inner wall of the pressing frame.

[0014] As a further aspect of the present invention: the conveyor belt of the plate is provided with a number of equidistant ventilation holes, each group of ventilation holes having multiple holes arranged along the width direction of the conveyor belt; an air pump is fixedly installed on one side of the mounting groove, the output end of the air pump is fixedly connected to an air extraction pipe, and one end of the air extraction pipe extends to the middle of the conveyor belt of the plate.

[0015] As a further aspect of the present invention: an impression roller is rotatably mounted on one end of the inner wall of the bending mounting frame, and an impression groove is provided on the top surface of the workbench below the impression roller.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention divides the bending and sealing steps into steps such as stamping, flanging, folding, and pressing, so that the stress generated during the edge sealing and bending operation can be fully released. Compared with the existing one-time bending method, it causes less damage to the edge of the board and is less likely to twist or crack during the bending process. At the same time, during the processing, the board is limited only by the side of the board, so that the board can move laterally during the bending and sealing operation, thereby avoiding the problem of board deformation caused by bending after forcibly fixing the board.

[0017] The position and attitude of the movable frame are detected by setting displacement sensors. When each displacement sensor detects that the movable frame has moved to a predetermined position, it is determined that each pressing roller has moved to the predetermined position, which is the location of the imprint groove. At this position, downward pressure is applied to the board, so that the edge of the board can be folded at the imprint groove when it is lifted, thus ensuring the accuracy of the flanging process. The folding component of this application drives the edge of the board to complete the folding by horizontal pushing. During the folding process, the board can automatically undergo a certain amount of lateral pulling during the force process. Compared with the traditional rolling edge sealing and bending method, it causes less damage to the board.

[0018] By setting up an air pump to extract air and creating negative pressure at the vent, the board material is adsorbed and fixed, thus allowing the board material to move with the board material conveyor belt. Attached Figure Description

[0026] 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.

[0027] Please see Figures 1-6 In this embodiment of the invention, a cabinet side panel edge-sealing bending machine includes a workbench 1. A bending mounting frame 2 is fixedly connected to one side of the top of the workbench 1, and a positioning mounting frame 3 is fixedly connected to the other side of the top of the workbench 1. A feeding roller 4 is rotatably connected to one end of the inner wall of the positioning mounting frame 3. A through groove for the edge of the board to pass through is opened on the side of the bending mounting frame 2 and the positioning mounting frame 3 that are close to each other. An installation groove is opened in the middle of the workbench 1, and a board conveyor belt 9 is rotatably installed on the inner wall of the installation groove. The top surface height of the board conveyor belt 9 is the same as the top surface height of the workbench 1.

[0028] The inner wall of the bending mounting frame 2 is provided with a flange assembly, a folding assembly and a pressing assembly in sequence along the moving direction of the sheet conveyor belt 9. The flange assembly is used to fold the edge of the sheet 10 up, the folding assembly is used to fold the folded edge down, and the pressing assembly is used to press the edge of the folded sheet.

[0029] Please see Figure 2An impression roller 5 is rotatably mounted on one end of the inner wall of the bending mounting frame 2, and an impression groove 6 is provided on the top surface of the workbench 1 below the impression roller 5. This application divides the bending and sealing steps into steps such as impression, flanging, folding, and pressing, so that the stress generated during the edge sealing and bending operation can be fully released. Compared with the existing one-time bending method, it causes less damage to the edge of the plate and is less likely to twist or crack during the bending process. At the same time, during the processing, the plate 10 is limited only by the side of the plate 10, so that the plate 10 can move laterally during the bending and sealing operation, thereby avoiding the problem of plate deformation caused by bending after forcibly fixing the plate 10.

[0030] The flanging assembly includes a movable pressing unit 7 for pressing and positioning the edge of the sheet 10 and a lifting and folding unit for pushing the edge of the sheet 10 to fold.

[0031] Please see Figure 4 The movable pressing unit 7 includes a connecting frame 701. The top of the connecting frame 701 is fixedly connected to the inner wall of the bending mounting frame 2. A limit rod is fixedly connected to the middle of the connecting frame 701. A movable frame 702 is slidably connected to the middle of the limit rod. Several pushing rods 704 are fixedly connected to the bottom of the movable frame 702. A pressing roller 705 is rotatably connected to the bottom of the pushing rods 704. A return spring 703 is sleeved on the outer wall of the limit rod. Several displacement sensors are embedded on the inner wall of the connecting frame 701 near the positioning mounting frame 3. Please refer to [link / reference]. Figure 5 The position and attitude of the movable frame 702 are detected by setting displacement sensors. When all displacement sensors detect that the movable frame 702 has moved to a predetermined position, it is determined that all pressing rollers 705 have moved to the predetermined position, which is the position of the imprint groove 6. At this position, downward pressure is applied to the plate 10, so that the edge of the plate 10 can be folded at the imprint groove 6 when it is lifted, thus ensuring the accuracy of the flanging process. The lifting and folding unit includes a receiving groove, and a push plate 12 is rotatably connected to the inner wall of the receiving groove. A folding push rod 11 is provided below the push plate 12. The output end of the folding push rod 11 is slidably connected to the bottom of the push plate 12. The folding push rod 11 pushes the push plate 12 to rotate, thereby causing the edge of the plate 10 to be folded.

[0032] Please see Figure 6The folding assembly includes a pushing unit and a folding pushing unit. The folding pushing unit includes a horizontal pushing cover plate 13, a horizontal pushing guide rail 14 fixedly installed on the inner wall of the horizontal pushing cover plate 13, and a horizontal pushing folding plate 15 slidably installed on the inner wall of the horizontal pushing guide rail 14. The pushing unit includes a horizontal push rod 18, the output end of which is fixedly connected to a roller frame. A pressing roller 19 is rotatably installed on the inner wall of the roller frame. The height of the pressing roller 19 is higher than the height of the horizontal pushing folding plate 15, and the distance between the two is slightly greater than the thickness of the board 10. In this application, the folding assembly drives the edge of the board 10 to complete the folding by horizontal pushing. During the folding process, the board 10 can automatically undergo a certain amount of lateral stretching under force. Compared with the traditional rolling edge sealing bending method, the damage to the board 10 is smaller.

[0033] Please see Figure 3 and Figure 5 The positioning mounting frame 3 has two positioning components 8 inside, which are respectively set to the flange assembly and the folding assembly. The positioning component 8 includes a lifting push rod 801, which includes a lifting frame 802. A side positioning unit is fixedly installed at one end of the lifting frame 802. The side positioning unit includes a support plate 803. Several side guide wheels 804 are rotatably connected to the middle of the support plate 803. The positioning unit limits the two sides of the plate 10 so that the position of the plate 10 can be stably aligned with the flange assembly and the folding assembly, thereby improving the processing stability. In order to limit the end of the plate 10, a limit push rod 805 is fixedly connected to one end of the support plate 803. An end baffle is fixedly connected to the output end of the limit push rod 805.

[0034] To limit the movement of plates 10 of different lengths, an adjusting guide rail is fixedly installed at the other end of the lifting frame 802. A movable positioning unit is slidably installed on the inner wall of the adjusting guide rail. The movable positioning unit has the same structure as the side positioning unit.

[0035] Please see Figure 6 To achieve edge sealing of the folded sheet 10, the pressing assembly includes a pressing push rod 16, the output end of which is fixedly connected to a pressing frame, and a pressing disc 17 is rotatably mounted on the inner wall of the pressing frame, with the edge of the pressing disc 17 being inclined.

[0036] Due to operations such as flanging and butt welding, the friction between the sheet metal 10 and the device structure increases. To ensure that the sheet metal conveyor belt 9 can stably move the sheet metal, please refer to [the relevant documentation / reference needed]. Figure 5The conveyor belt 9 has several sets of equidistant ventilation holes 901 on its surface. Each set of ventilation holes 901 has multiple holes and is arranged along the width of the conveyor belt 9. An air pump 902 is fixedly installed on one side of the mounting groove. An air extraction pipe is fixedly connected to the output end of the air pump 902. One end of the air extraction pipe extends to the middle of the conveyor belt 9. By setting the air pump 902 to extract air, a negative pressure is generated at the ventilation hole 901, which achieves adsorption and fixation of the board 10, so that the board 10 can move with the conveyor belt 9.

[0037] In use, the sheet material 10 to be processed is first placed on the sheet conveyor belt 9. Please refer to [link to relevant documentation]. Figure 1 The plate 10 is drawn into two through slots along its two sides. A pneumatic pump 902 draws air through vent 901 to create negative pressure, adsorbing the plate and causing it to move due to the rotation of the plate conveyor belt 9. (See also...) Figure 2 When the board 10 passes through the embossing roller 5, the embossing roller 5 presses out a bending mark at the position where the board 10 is to be bent.

[0038] Please see Figure 5 When the plate 10 moves to the position of the flanging assembly, the plate conveyor belt 9 and the air pump 902 stop working. The positioning assembly 8 at the corresponding position of the flanging assembly starts to position the plate 10. Specifically, the lifting push rod 801 drives the lifting frame 802 to rise, so that the side positioning unit and the movable positioning unit move to the top of the worktable 1. At this time, the side positioning unit and the movable positioning unit are located on both sides of the plate 10. Then, the guide rail is adjusted to drive the movable positioning unit to move, and the side positioning unit is used to limit the plate 10. At this time, the two sides of the plate 10 are in contact with the limit guide wheels on the two positioning units. Then, the limit push rod 805 drives the end baffle to rise, and limits the end of the plate 10.

[0039] Then the edge-flipping operation begins. Specifically, the folding push rod 11 drives the pressing plate 12 to rotate, causing the edge of the plate 10 to lift up. The lifted plate 10 contacts each of the lower pressing rollers 705 and pushes each of the pressing rods 704 to move, thereby driving the movable frame 702 to slide along the limit rod until the movable frame 702 moves to the limit position and stops, so that each of the lower pressing rollers 705 no longer moves. At this time, the pushing of the folding push rod 11 and the pressing plate 12 continues to drive the edge of the plate 10 to complete the folding. Then the positioning component 8 moves down and disengages from the plate 10. Then the vacuum pump 902 is started, and the negative pressure of the air vent 901 is used to adsorb and fix the plate 10. The plate conveyor belt 9 is started to drive the plate 10 to move.

[0040] Please see Figure 6When the sheet material 10 moves to the position of the folding assembly, the sheet material conveyor belt 9 and the vacuum pump 902 stop working. The positioning assembly 8 for the folding assembly position is activated to position the sheet material 10, and then the folding operation begins. Specifically, the horizontal push guide rail 14 drives the horizontal push folding plate 15 to move, pushing the bottom of the folded edge. In conjunction with the horizontal push rod 18, the push roller 19 is moved to fold the folded edge downward. After the folding is completed, the horizontal push rod 18 and the horizontal push folding plate 15 are reset. Then, the vacuum pump 902 and the sheet material conveyor belt 9 are activated to move the sheet material 10. When the sheet material 10 passes under the pressing assembly, the pressing push rod 16 drives the pressing plate 17 to move down. The pressing plate 17 contacts the edge of the folded sheet material 10 to press and seal the edge.

Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention.
