Description

Technical Field

[0001] This invention relates to the field of press-fitting equipment, specifically a press-fitting device for edge wrapping processing. Background Technology

[0002] To enhance the edge protection of sheet materials, edge banding is typically required, with metal edge banding being the most durable option. While adhesive bonding is commonly used for edge banding, it's not suitable for firmly binding metal edge banding sheets. However, existing pressing equipment has limited contact surfaces, making it unsuitable for simultaneously pressing and binding longer edge banding sheets. This results in uneven surfaces, wrinkles, and other quality issues, with corner binding being particularly challenging, often requiring subsequent finishing touches to conceal the corners. Therefore, this paper proposes a pressing device for edge banding processing to address these problems. Summary of the Invention

[0003] The purpose of this invention is to provide a pressing device for edge banding processing in order to solve the above-mentioned problems.

[0004] The present invention achieves the above-mentioned objective through the following technical solution: a pressing device for edge binding processing, comprising a first hydraulic cylinder, a shaping mechanism, a second hydraulic cylinder, a side-moving follower plate, and a third hydraulic cylinder. The cylinder body of the first hydraulic cylinder is fixedly installed on one side of the frame, and the output end of the first hydraulic cylinder is fixedly connected to a T-shaped frame. The third hydraulic cylinder located on both sides of the middle part of the T-shaped frame is connected to a servo motor linear motion module. Electromagnetic groups are installed at both ends of the strip slide in the shaping mechanism, and the two electromagnet groups are in a repulsive state with the two sets of magnetic strips respectively. The two sets of magnetic strips are respectively installed at both ends of the back of the end face shaping strip frame in the shaping mechanism, and a fine groove is opened on the structural surface between each set of magnetic strips. The output end of the second hydraulic cylinder is connected to the back of the side-moving follower plate, and the cylinder body end of the second hydraulic cylinder is installed on a carrier. The carrier is installed in the middle of the rotating shaft, and torsion springs are fitted at both ends of the rotating shaft. The rotating shaft is installed inside the side groove.

[0005] In a further technical solution, the servo motor linear motion module is located in the middle of the T-shaped frame, and the traction component in the servo motor linear motion module is connected to the middle of the strip slide, and the slide rail structure in the servo motor linear motion module is slidably connected to the back of the strip slide.

[0006] In a further technical solution, the side groove is provided in two sets, and the two sets of side grooves are respectively located at both ends of the T-shaped frame. Each set of side grooves is provided in three places, and the middle area between the two ends of the T-shaped frame is aligned with the strip hole located on the other side of the frame.

[0007] In a further technical solution, two sets of guide rails are symmetrically installed on the other side of the frame, and each set of guide rails is slidably mounted with a sliding plate. A fourth hydraulic cylinder is installed on the top of the sliding plate, and the output end of the fourth hydraulic cylinder is connected to an L-shaped limiting plate.

[0008] In a further technical solution, two L-shaped limiting plates are provided, and the two L-shaped limiting plates form a clamping and fixing structure for the workpiece to be edged between the two sliding plates. A positioning screw is threadedly connected to the middle of the outer side of the L-shaped limiting plate, and one end of the positioning screw is threadedly connected to the corresponding screw hole on the other side of the T-shaped frame.

[0009] In a further technical solution, the end face shaping frame is a deformable material structure, and the portion between the two ends of the end face shaping frame is fixedly connected to the strip slide.

[0010] In a further technical solution, both ends of the back side of the end face shaping frame are formed into a force-applied and shapeable structure through a set of corresponding fine grooves.

[0011] A further technical solution is that the electromagnet group generates repulsive forces of different strengths between the magnet strips in different parts of the same group, and the electromagnet group is composed of multiple electromagnets.

[0012] In a further technical solution, the side-moving pressure plate surface is magnetically attached with an edge-sealing sheet.

[0013] The beneficial effects of this invention are: By energizing an electromagnet group composed of several electromagnets, a strong magnetic field is generated, which creates a repulsive force on a group of magnetic strips in front. At the same time, combined with the fine grooves located in the structure between the magnetic strips, the end face shaping frame can be in a fully functional state until the square edge-wrapping sheet is squeezed and wrapped around the chamfered corner of the workpiece to be wrapped. This solves the problem of inconvenient pressing and wrapping at the chamfered corner of the workpiece to be wrapped, and achieves the effect of integrated and complete edge wrapping. The servo motor linear motion module drives the connected shaping mechanism to move back and forth, so that the end face shaping frame in the shaping mechanism performs reciprocating ironing on the top contact edge sheet, improving the flatness of the edge surface. Combined with the horizontally distributed side moving pressure plate, it squeezes and binds the folded edge of the edge sheet, effectively preventing the edge from loosening after reshaping. The first hydraulic cylinder extends to move the side-moving pressure plate connected to the T-shaped frame forward, and the corresponding part of the side-moving pressure plate is always in contact with the edge of the workpiece to be edged. The third hydraulic cylinder is in a follow-up retraction state while ensuring that the end face shaping strip is in contact with the back of the edged sheet without detaching, so as to prevent obstruction to the extension of the first hydraulic cylinder and its connected parts. At the same time, the second hydraulic cylinder is also in a follow-up extension state, which is conducive to the side-moving pressure plate making full contact with the part of the edged sheet that is pressed and folded in real time.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0021] Please see Figure 1-6 As shown, a pressing device for edge banding includes a first hydraulic cylinder 1, a shaping mechanism 2, a second hydraulic cylinder 313, a side-moving follower plate 4, and a third hydraulic cylinder 5. The cylinder body of the first hydraulic cylinder 1 is fixedly mounted on one side of the frame 12, and the output end of the first hydraulic cylinder 1 is fixedly connected to a T-shaped frame 3. The third hydraulic cylinder 5, located on both sides of the middle part of the T-shaped frame 3, is connected to a servo motor linear motion module 6. Electromagnetic magnet groups 221 are installed at both ends of the strip slide 220 in the shaping mechanism 2, and the two electromagnetic magnet groups 221 are respectively connected to two sets of magnetic strips. The blocks 211 are in a repulsive state. The two sets of magnetic blocks 211 are respectively installed at both ends of the back of the end face shaping frame 210 in the shaping mechanism 2. A fine groove 212 is opened on the structural surface between each set of magnetic blocks 211. The output end of the second oil cylinder 313 is connected to the back of the side moving pressure plate 4. The cylinder end of the second oil cylinder 313 is installed on the carrier 312. The carrier 312 is installed in the middle of the rotating shaft 311. Both ends of the rotating shaft 311 are fitted with torsion springs. The rotating shaft 311 is installed inside the side groove 310.

[0022] The servo motor linear motion module 6 is located in the middle of the T-shaped frame 3, and the traction component in the servo motor linear motion module 6 is connected to the middle of the strip slide 220. The slide rail structure in the servo motor linear motion module 6 is slidably connected to the back of the strip slide 220. By running the servo motor linear motion module 6, the connected strip slide 220 is moved left and right. Combined with the end face shaping frame 210 on the strip slide 220, the driven end face shaping frame 210 can be used to reciprocate and iron the edge of the edge-wrapped sheet 14.

[0023] like Figure 2 , Figure 5 and Figure 6As shown, the edge groove 310 is provided in two sets, and the two sets of edge groove 310 are respectively provided at both ends of the T-shaped frame 3. Each set of edge groove 310 has three. The middle area between the two ends of the T-shaped frame 3 is aligned with the strip hole 12a on the other side of the frame 12. By setting the edge groove 310 in groups of three, it plays the role of implementing the mounting and connection structure on the back of the side moving pressure plate 4. Through the strip hole 12a, the edge of the workpiece 13 to be edged can pass through the strip hole 12a and be placed at the edged station.

[0024] Combination Figure 6 As shown, two sets of guide rails 7 are symmetrically installed on the other side of the frame 12, and each set of guide rails 7 is slidably installed with a sliding plate 8. A fourth oil cylinder 9 is installed on the top of the sliding plate 8, and the output end of the fourth oil cylinder 9 is connected to an L-shaped limiting plate 11. There are two L-shaped limiting plates 11, and the two L-shaped limiting plates 11 form a clamping and fixing structure for the workpiece 13 to be edged between the two sliding plates 8. A positioning screw 10 is threadedly connected to the middle of the outer side of the L-shaped limiting plate 11, and one end of the positioning screw 10 is threadedly connected to the corresponding screw hole 12b on the other side of the T-shaped frame 3. When the workpiece 13 to be edged is placed between the two L-shaped limiting plates 11, the two sets of fourth hydraulic cylinders 9 distributed vertically extend and move inward on the connected L-shaped limiting plates 11 respectively, so as to fix and bind the workpiece 13 to be edged through the two L-shaped limiting plates 11. After the workpiece 13 to be edged is fixed, the L-shaped limiting plates 11 are pushed to move towards the strip hole 12a until the end edge of the workpiece 13 to be edged passes through the strip hole 12a and is in the edged position. The positioning screw 10 is rotated and its one end is threaded into the corresponding screw hole 12b on the frame 12 to prevent the L-shaped limiting plates 11 from moving after adjustment and fixing.

[0025] Combination Figure 4 As shown, the end face shaping frame 210 is a deformable material structure, and the portion between the two ends of the end face shaping frame 210 is fixedly connected to the strip slide 220. Both ends of the back side of the end face shaping frame 210 are formed into a force-applied shaped structure through a set of corresponding fine grooves 212.

[0026] Furthermore, the electromagnet group 221 generates repulsive forces of different strengths between the magnet strips 211 at different locations in the same group, and the electromagnet group 221 is composed of multiple electromagnets, and the side-moving pressure plate 4 has a magnetically attached edge-sealing sheet 14 on its surface.

[0027] Working principle: When the end surface of the workpiece 13 to be bound is in contact with the middle position of the binding sheet 14 between the two side-moving pressure plates 4, the third cylinder 5 first extends to press the connected end face shaping frame 210 against the back of the binding sheet 14, which can tightly adhere the corresponding part of the binding sheet 14 to the end surface of the workpiece 13 to be bound. Then the first cylinder 1 extends to move the side-moving pressure plate 4 connected by the T-shaped frame 3 forward, and the corresponding part of the side-moving pressure plate 4 is always in contact with the edge of the workpiece 13 to be bound. The third cylinder 5 is in a follow-up retraction state while ensuring that the end face shaping frame 210 does not detach from the back of the binding sheet 14, so as to prevent obstruction to the extension of the first cylinder 1 and its connected part. At the same time, the second cylinder 313 is also in a follow-up extension state, which is conducive to the side-moving pressure plate 4 making full contact with the pressed part of the binding sheet 14 in real time. When the side-moving pressure plate 4 moves to a horizontal state, the corresponding part of the side-moving pressure plate 4 is always in contact with the edge of the workpiece 13 to be edged. The second oil cylinder 313 extends and pushes the side-moving pressure plate 4 onto the folded edge of the edged sheet 14 to prevent loosening and enhance the folding and shaping effect. At this time, the edged sheet 14 at the end of the workpiece 13 to be edged is processed. Under the action of the end face shaping frame 210 and the edged sheet 14 at the end of the workpiece 13 to be edged always touching each other, the servo motor linear motion module 6 drives the connected shaping mechanism 2 to move back and forth, so that the end face shaping frame 210 in the shaping mechanism 2 performs reciprocating ironing on the edged sheet 14 that is touching each other, improving the flatness of the edged surface. Combined with the side-moving pressure plate 4 distributed vertically and horizontally, it squeezes and binds the folded edge of the edged sheet 14, effectively preventing the edged reshaping from loosening. When the end of the end-face shaping frame 210 with electromagnet assembly 221 moves to the chamfered corner of the workpiece 13 to be edged, the electromagnet assembly 221, composed of several electromagnets, is energized to generate a strong magnetic field that repels a group of magnet blocks 211 in front. At the same time, combined with the fine groove 212 located in the structure between the magnet blocks 211, the end-face shaping frame 210 can be in a fully functional state until the square edge-wrapping sheet 14 is partially squeezed and wrapped around the chamfered corner of the workpiece 13 to be edged. This solves the problem of inconvenient pressing and edge wrapping at the chamfered corner of the workpiece 13 to be edged, and achieves the effect of integrated and complete edge wrapping.

[0028] In summary, the difference of this invention lies in: 1. By energizing an electromagnet group 221 composed of several electromagnets, a strong magnetic field is generated, which forms a repulsive force on a group of magnetic strips 211 in front. At the same time, combined with the fine grooves 212 located in the structure between the magnetic strips 211, the end face shaping frame 210 can be in a fully functional state until the square edge-wrapping sheet 14 is partially squeezed and wrapped around the chamfered corner of the workpiece 13 to be edged. This solves the problem of inconvenient pressing and edge wrapping at the chamfered corner of the workpiece 13 to be edged, and achieves the effect of integrated and complete edge wrapping. 2. The servo motor linear motion module 6 drives the connected shaping mechanism 2 to move back and forth, so that the end face shaping frame 210 in the shaping mechanism 2 performs reciprocating ironing on the top contact edge sheet 14, improving the flatness of the edge surface. Combined with the horizontally distributed side moving pressure plate 4, the edge of the edge sheet 14 is squeezed and bound, effectively preventing the edge from loosening after reshaping. 3. The first hydraulic cylinder 1 extends to move the side-moving pressure plate 4 connected to the T-shaped frame 3 forward, and the corresponding part of the side-moving pressure plate 4 is always in contact with the edge of the workpiece 13 to be edged. The third hydraulic cylinder 5 is in a follow-up retraction state while ensuring that the end face shaping frame 210 is in contact with the back of the edged sheet 14 without detaching, so as to prevent obstruction to the extension of the first hydraulic cylinder 1 and its connected parts. At the same time, the second hydraulic cylinder 313 is also in a follow-up extension state, which is conducive to the side-moving pressure plate 4 making full contact with the edged sheet 14 in real time.
