A CNC machine tool for bending wooden boxes

Abstract

This invention relates to the field of wood processing technology, specifically to a CNC machine tool bending device for processing wooden boxes. It includes a base, a processing table, an extrusion assembly, two limiting plates, two torsion springs, two support plates, two slide rails, four connectors, a connecting rope, and a support component. The processing table has a processing groove. The limiting plates and support plates are combined to clamp the wood. The support plates are supported by the torsion springs, and when pressed downwards, the support plates can rotate to prevent the wood from breaking. The connecting rope is used to drive the two limiting plates to slide downwards at an angle, ensuring that the two limiting plates always clamp the wood. This invention uses the combination of torsion springs and support plates to offset the force on the edges of the wood, preventing breakage. Furthermore, the slide rails and connecting rope achieve continuous clamping of the wood and position it, thus solving the problem that existing equipment easily breaks the edges first during bending, leading to wood damage.

Description

Technical Field

[0001] This invention relates to the field of wood processing technology, and in particular to a bending device for CNC machine tools used in wood box processing. Background Technology

[0002] A wood bending device is used to bend and shape wood boards. It uses a mold to constrain and compress the wood board, shaping it into a predetermined form to meet usage requirements. This device replaces manual bending, significantly improving efficiency and reducing production costs. With rising living standards, large quantities of wood are often used for interior decoration and furniture design. During wood processing, bending is required for aesthetic purposes. Existing bending devices require placing the wood on a top plate with an elastic sheet between it and the board. However, these elastic sheets lack positioning functionality, causing the wood to shift during bending. This requires workers to correct the shift with a hammer, compromising efficiency and potentially damaging the wood's integrity. Furthermore, existing bending devices require stopping to change the mold head for different shapes, which is cumbersome and further impacts processing efficiency, resulting in poor equipment flexibility.

[0003] An existing patent discloses a CNC bending machine for processing wooden boxes (CN116423596A), which includes a fixed box, a limiting plate, a spring, a die head, a rotating plate, and a support arm. The machine is used by rotating two rotating plates in conjunction with the support arm. It can drive the top plate to compress the wood and the spring, and work with the die head to shape the wood. An L-shaped plate set on the spring, together with the compression plate, can fix the wood inside. The L-shaped plate is actually U-shaped and is used to fix the wood. It can prevent the wood from warping or shifting during bending.

[0004] However, when this equipment is used for bending, the edges of the wood get stuck inside the L-shaped plate, and the edge is easily broken off when the die head moves downwards, which can damage the wood. Summary of the Invention

[0005] The purpose of this invention is to provide a bending device for CNC machine tools used in wooden box processing, which aims to solve the problem that existing equipment tends to break off the edges first during bending, thus damaging the wood.

[0006] To achieve the above objectives, the present invention provides a bending device for a CNC machine tool used for processing wooden boxes, comprising a base, a processing table, an extrusion assembly, two limiting plates, two torsion springs, two support plates, two slide rails, four connecting pieces, a connecting rope, and a support member. The processing table has a processing groove; the processing table is fixed above the base; the extrusion assembly is disposed on the processing table; the two limiting plates are disposed on the left and right sides of the processing groove on the processing table; the two support plates are rotatably disposed below the two limiting plates; the two torsion springs are fixedly connected to the two limiting plates and to the two support plates; the two slide rails are disposed on the front and rear sides of the processing groove on the processing table; the four connecting pieces are slidably connected to the two slide rails and to the sides of the two limiting plates; the connecting rope is fixedly connected to the two support plates; and the support member is disposed on the base.

[0007] The extrusion assembly includes a hydraulic cylinder, a rotary seat, a rotary motor, a mounting base, and multiple extrusion heads. The hydraulic cylinder is fixed to the processing table; the rotary seat is fixed to the output end of the hydraulic cylinder; the rotary motor is fixed to one side of the rotary seat; the mounting base is fixedly connected to the output end of the rotary motor; and the multiple extrusion heads are disposed on the mounting base.

[0008] The connecting component includes a sliding block, an adjusting seat, and a connecting block. The sliding block is slidably disposed in the slide rail; the adjusting seat is rotatably disposed on the side of the sliding block; the connecting block and the adjusting seat are slidably connected and fixedly connected to the limiting plate.

[0009] The connector further includes a spring and a telescopic rod, the telescopic rod being fixedly connected to the adjusting seat and the connecting block; the spring is disposed on the outside of the telescopic rod.

[0010] The support component includes multiple fixed support blocks, two hydraulic rods, multiple movable support blocks, and a lifting seat. The multiple fixed support blocks are fixed on the base. The multiple movable support blocks and the multiple fixed support blocks are arranged alternately. The two hydraulic rods are fixed above the base. The lifting seat is fixedly connected to the multiple movable support blocks and to the output ends of the two hydraulic rods.

[0011] The aforementioned CNC machine tool bending equipment for processing wooden boxes further includes an electric push rod and a push plate, wherein the electric push rod is fixed on the base; and the push plate is disposed at the output end of the electric push rod.

[0012] The bending equipment of the CNC machine tool for processing wooden boxes further includes a mounting block and a clamping block. The mounting block is fixedly connected to the output end of the electric push rod and rotatably connected to the push block. The clamping block is located at the lower end of the push block.

[0013] This invention discloses a CNC machine tool bending device for processing wooden boxes. The base provides overall support, the processing table is used for height adjustment and to reserve bending space, and the processing groove is used to provide space for bending the wood. The pressing assembly moves downwards to press the wood. Two limiting plates and two supporting plates are combined to form two U-shaped structures with opposite openings for clamping the wood. The supporting plates are supported by torsion springs. When pressing downwards, the supporting plates can rotate to avoid continuously supporting the wood and causing it to break. Four connecting pieces are divided into two groups, located on both sides of the two limiting plates, for mounting the limiting plates onto the slide rails. The slide rails are arc-shaped, allowing the limiting plates to move diagonally downwards. A connecting rope connects the two supporting plates, and during pressing, the connecting rope is located below the wood. When pressing downwards, the wood... Moving downwards, the connecting rope drives the two support plates and two limiting plates to slide obliquely downwards, ensuring that the two limiting plates always clamp the wood, thus achieving continuous clamping and positioning of the wood and preventing the support plates from rotating and causing the wood to fall directly. At this time, the force on the edge of the wood is offset by the torsion spring, preventing it from breaking. When it moves onto the support member, the lower support member supports the wood, causing it to begin to bend, while the limiting plate is located at the edge of the support member and does not contact it or interfere with the bending process. This invention uses the combination of the torsion spring and the support plate to offset the force on the edge of the wood and prevent it from breaking. Furthermore, the slide rail and the connecting rope achieve continuous clamping and positioning of the wood, preventing misalignment of the bending position. This solves the problem that existing equipment easily breaks off the edge part first during bending, leading to damage to the wood. Attached Figure Description

Figures 1-4 , Figure 1 This is a schematic diagram of the structure of a CNC machine tool bending equipment for processing wooden boxes according to the first embodiment of the present invention; Figure 2 This is a top view of a CNC machine tool bending equipment for processing wooden boxes according to the first embodiment of the present invention; Figure 3 This is a cross-sectional view of a CNC machine tool bending equipment for processing wooden boxes according to the first embodiment of the present invention; Figure 4 This is a bending device for a CNC machine tool used in the processing of wooden boxes, according to the first embodiment of the present invention. Figure 3 A magnified view of detail A.

[0024] This invention provides a bending device for a CNC machine tool used in wooden box processing: it includes a base 101, a processing table 102, an extrusion assembly, two limiting plates 103, two torsion springs 104, two support plates 105, two slide rails 106, four connecting parts, a connecting rope 107, and a support member. The extrusion assembly includes a hydraulic cylinder 109, a rotating seat 110, a rotary motor 111, a mounting seat 112, and multiple extrusion heads 113. The connecting parts include a sliding block 114, an adjusting seat 115, a connecting block 116, a spring 117, and a telescopic rod 118. The support member includes multiple fixed support blocks 119, two hydraulic rods 120, multiple movable support blocks 121, and a lifting seat 122. The processing table 102 has a processing groove 108.

[0025] The aforementioned solution addresses the problem that existing equipment often breaks off the edges during bending, leading to wood damage. Understandably, the solution can counteract the force on the wood edges, preventing breakage, and also enables continuous clamping of the wood to position it correctly, preventing misalignment during bending.

[0026] In this embodiment, the processing table 102 is fixed above the base 101; the extrusion assembly is disposed on the processing table 102; two limiting plates 103 are disposed on the left and right sides of the processing groove 108 of the processing table 102; two support plates 105 are rotatably disposed below the two limiting plates 103; two torsion springs 104 are fixedly connected to the two limiting plates 103 and to the two support plates 105; two slide rails 106 are disposed on the front and rear sides of the processing groove 108 of the processing table 102; four connecting pieces are slidably connected to the two slide rails 106 and to the two limiting plates 103. The system is connected on both sides; the connecting rope 107 and the two support plates 105 are fixedly connected; the support member is mounted on the base 101; the base 101 provides overall support; the processing table 102 is used to raise the height and reserve bending space; the processing groove 108 is used to leave space for bending the wood; the pressing assembly is used to move downwards to press the wood; the two limiting plates 103 and the two support plates 105 combine to form two U-shaped structures with opposite openings for clamping the wood; the support plates 105 are supported by the torsion spring 104, and when pressed downwards, the support plates 105 can rotate to avoid continuously supporting the wood and causing it to break or be damaged. The four connectors are divided into two groups, located on both sides of the two limiting plates 103, for mounting the limiting plates 103 onto the slide rail 106. The slide rail 106 is arc-shaped, allowing the limiting plates 103 to move diagonally downwards. The connecting rope 107 connects the two supporting plates 105. During compression, the connecting rope 107 is located below the wood. When the wood is compressed downwards, it moves downwards, and the connecting rope 107 drives the two supporting plates 105 and the two limiting plates 103 to slide diagonally downwards, ensuring that the two limiting plates 103 always clamp the wood, thereby achieving continuous clamping and positioning of the wood, preventing the supporting plates 105 from rotating, and allowing the wood to move directly. The wood falls off; at this time, the force on the edge of the wood is offset by the torsion spring 104, which can prevent it from breaking; when it moves onto the support, the support below supports the wood, causing it to begin to bend, while the limiting plate 103 is located at the edge of the support and does not contact it to interfere with the bending process; the present invention uses the combination of the torsion spring 104 and the support plate 105 to offset the force on the edge of the wood and prevent it from breaking; and through the slide rail 106 and the connecting rope 107, the wood is continuously clamped and its position is positioned to avoid misalignment of the bending position, thereby solving the problem that existing equipment is prone to breaking the edge part first during bending, which leads to damage to the wood.

[0028] Secondly, the sliding block 114 is slidably disposed in the slide rail 106; the adjusting seat 115 is rotatably disposed on the side of the sliding block 114; the connecting block 116 is slidably connected to the adjusting seat 115 and fixedly connected to the limiting plate 103; the sliding block 114 is used to be installed in the slide rail 106, and the connecting block 116 can slide up and down in the adjusting seat 115 to connect the limiting block. The upper and lower positions can be adjusted more flexibly according to the specific curvature, which is convenient for effectively clamping the wood.

[0029] Furthermore, the telescopic rod 118 and the adjusting seat 115 are fixedly connected, and are also fixedly connected to the connecting block 116; the spring 117 is disposed on the outside of the telescopic rod 118; the telescopic rod 118 is used to limit the spring 117, and under the action of the spring 117, the connecting block 116 is allowed to spring back upward, and reset after clamping is completed.

[0030] Finally, multiple fixed support blocks 119 are fixed to the base 101; multiple movable support blocks 121 and multiple fixed support blocks 119 are staggered; two hydraulic rods 120 are fixed above the base 101; the lifting seat 122 is fixedly connected to the multiple movable support blocks 121 and to the output ends of the two hydraulic rods 120; the multiple fixed support blocks 119 have the same curvature to provide one bending curvature, the multiple movable support blocks 121 have the same curvature to provide a second bending curvature, the movable support blocks 121 are connected to the lifting seat 122 and can move up and down under the action of the hydraulic rods 120 to provide different bending curvature options.

[0031] During use, the base 101 provides overall support, the processing table 102 is used to increase height and reserve bending space, and the processing groove 108 is used to leave space for bending the wood; the pressing assembly is used to move downwards to press the wood; the two limiting plates 103 and the two supporting plates 105 combine to form two U-shaped structures with their openings facing each other for clamping the wood; the supporting plates 105 are supported by the torsion spring 104; when pressed downwards, the supporting plates 105 can rotate to avoid continuously supporting the wood and causing it to break; the four connecting pieces are divided into two groups, located on both sides of the two limiting plates 103, for installing the limiting plates 103 onto the slide rail 106. The shape is arc-shaped, allowing the limiting plate 103 to move obliquely downwards; the connecting rope 107 is used to connect the two supporting plates 105, and the connecting rope 107 is located below the wood during compression; when the wood is compressed downwards, the wood moves downwards, and the connecting rope 107 drives the two supporting plates 105 and the two limiting plates 103 to slide obliquely downwards, so that the two limiting plates 103 always clamp the wood, thereby achieving continuous clamping and positioning of the wood, preventing the supporting plates 105 from rotating and causing the wood to fall off directly; at this time, the force on the edge of the wood is offset by the torsion spring 104, which can prevent it from breaking; when it moves onto the support member, the lower support member supports the wood, causing it to begin to bend, while the limiting plate 103 is located on the support member.

Then it is reset; the multiple fixed support blocks 119 have the same arc, which is used to provide a bending arc, and the multiple movable support blocks 121 have the same arc, which is used to provide a second bending arc. The movable support blocks 121 are connected to the lifting seat 122 and can move up and down under the action of the hydraulic rod 120 to provide different bending arc selections; the present invention uses the combination of the torsion spring 104 and the support plate 105 to offset the force on the edge of the wood and prevent it from being broken; and uses the slide rail 106 and the connecting rope 107 to realize the continuous clamping of the wood and position it to prevent the bending position from being misaligned, thereby solving the problem that existing equipment is prone to breaking the edge part first when processing bending, which leads to damage to the wood.
