Description

Technical Field

[0001] This invention relates to the field of precision aluminum profile processing technology, and in particular to a fully automatic high-precision cutting device specifically designed for aluminum profiles. Background Technology

[0002] Valve bodies are common components in precision equipment, used to control the opening and closing of fluid passages in precision equipment, and play a key role in the stable and efficient operation of precision equipment.

[0003] In existing technologies, the aluminum profile blanks required for manufacturing valve bodies are mostly produced by manually cutting aluminum rods to the required length, followed by shaping to ensure the aluminum profile blanks meet the precision requirements of the valve body. This processing method has low production efficiency, long production time, and high labor costs. At the same time, the blanks cut manually have large perpendicularity, flatness, and roughness of the cut end faces, resulting in low cutting accuracy and poor consistency. Summary of the Invention

[0004] To address the shortcomings of existing production technologies, the applicant provides a structurally sound, fully automated, high-precision cutting device specifically designed for aluminum profiles. By incorporating a feeding device, a cutting device, a clamping device, and a floating feeding device, the device enables efficient and high-precision cutting of workpieces, thereby shortening processing time and improving production efficiency. Simultaneously, it reduces labor costs, and the fully automated cutting method ensures high consistency of the processed workpieces.

[0005] The technical solution adopted in this invention is as follows:

[0006] A fully automatic high-precision cutting equipment for aluminum profiles includes a feeding platform for feeding materials, a floating feeding device connected to the discharge end of the feeding platform, a pressing and cutting unit connected to the rear end of the floating feeding device, and both the pressing and cutting unit and the floating feeding device are supported by a frame.

[0007] The working end of the floating feeding device clamps the workpiece on the top of the feeding table and drives the workpiece to move in a straight line along the first horizontal direction, thereby transporting the workpiece to the feeding end of the pressing and cutting unit.

[0008] The clamping and cutting unit includes a cutting device for cutting the workpiece and a clamping device for clamping the workpiece. A feeding device is installed at the bottom of the cutting device. The feeding device drives the cutting device to move linearly along the second horizontal direction, thereby cutting the workpiece clamped by the working end of the clamping device.

[0009] The floating feeding device is equipped with a first floating cylinder and a second floating cylinder. The floating feeding device floats in the vertical direction through the first floating cylinder, so that the horizontal working end face of the floating feeding device is higher than the horizontal working end face of the pressing device.

[0010] The floating feeding device floats along the second horizontal direction via the second floating cylinder, thereby causing the vertical working end face of the floating feeding device to shift relative to the vertical working end face of the pressing device along the second horizontal direction.

[0011] As a further improvement to the above technical solution:

[0012] The first horizontal direction is perpendicular to the second horizontal direction.

[0013] The structure of the feeding device is as follows: it includes a feeding mounting frame, the top of which is fixed with several parallel feeding slide rails, the top of each feeding slide rail is fitted with several feeding sliders, and the top of each feeding slider is fitted with a cutting device.

[0014] The feed mounting bracket has a feed motor fixed on one side. The output end of the feed motor is connected to the feed screw. The feed screw is arranged parallel to the feed slide rail. A feed connecting seat is installed on the outer circumference of the feed screw through a feed nut. The feed connecting seat is used to connect the cutting device.

[0015] The feed motor drives the feed screw to rotate, thereby causing the feed connecting seat to move linearly along the axial direction of the feed screw through the feed nut, which in turn drives the cutting device to move linearly along the feed slide rail.

[0016] The cutting device has the following structure: it includes a cutting mounting frame, a cutting motor is fixed on the top of the cutting mounting frame, and the output end of the cutting motor is connected to a drive pulley;

[0017] A main shaft is rotatably mounted on the cutting mounting bracket below the cutting motor via bearings. A driven pulley is fixed to one end of the main shaft, and a V-belt is fitted between the driven pulley and the driving pulley.

[0018] The other end of the spindle is fixed with a saw blade, one end of which extends to the outside of the cutting mounting bracket;

[0019] The cutting motor drives the active pulley to rotate, which in turn drives the driven pulley to rotate via a V-belt. The driven pulley then drives the saw blade to rotate via the main shaft, thereby enabling the saw blade to cut the workpiece.

[0020] The clamping device has the following structure: it includes a clamping mounting frame, a first clamping cylinder is fixed to the top of the clamping mounting frame, the output end of the first clamping cylinder is connected to a first clamping seat, a clamping table is fixed on the clamping mounting frame below the first clamping seat, the working end face of the clamping table is flat, a clamping grid is fixed on the clamping mounting frame on one side of the clamping table, the working end face of the clamping grid is flat, the clamping grid is arranged higher than the clamping table, so that the working end face of the clamping grid and the working end face of the clamping table form an L-shaped first limiting end face, thereby limiting the workpiece. Both the working end face of the clamping grid and the working end face of the clamping table have clearance grooves.

[0021] The other side of the clamping mounting bracket is fixed with a second clamping cylinder. The output end of the second clamping cylinder is connected to a second clamping seat. The second clamping seat is directly opposite the working end face of the clamping grid.

[0022] The first clamping cylinder drives the first clamping seat to move in a straight line along the vertical direction toward or away from the working end face of the clamping table. At the same time, the second clamping cylinder drives the second clamping seat to move in a straight line along the horizontal direction toward or away from the working end face of the clamping grid, thereby clamping or releasing the workpiece on the first limiting end face.

[0023] The floating feeding device has the following structure: it includes a floating feeding mounting frame, the bottom of which is supported by a first support and a second support respectively. A feeding motor is fixed on one side of the floating feeding mounting frame. The output end of the feeding motor is connected to a feeding screw. A slide is fitted on the outer circumference of the feeding screw. Several feeding sliders are fitted on the bottom of the slide. The feeding sliders are fitted with several corresponding feeding slide rails. The several feeding slide rails are fixed parallel to the top of the floating feeding mounting frame.

[0024] The feeding motor drives the feeding screw to rotate, thereby causing the slide to move linearly along the feeding slide rail;

[0025] The top of the slide is provided with a clamping platform, the working end face of the clamping platform is flat, and several parallel clamping slide rails are fixed on the top of the slide next to the clamping platform. A clamping slider is installed on each clamping slide rail, and a clamping seat is fixed on the top of the clamping slider. The clamping seat is connected to the output end of the clamping cylinder.

[0026] A clamping grid is provided on the opposite side of the clamping seat. The clamping grid is fixed to one side of the slide. The working end face of the clamping grid is flat and higher than the working end face of the clamping table, thus forming an L-shaped second limiting end face. The second limiting end face limits the workpiece.

[0027] The clamping cylinder drives the clamping seat to move linearly along the clamping slide rail toward or away from the working end face of the clamping grid, thereby clamping or releasing the workpiece on the second limiting end face.

[0028] An auxiliary roller is installed on one side of the slide block, and the top outer contour of the auxiliary roller is flush with the working end face of the clamping table.

[0029] The bottom of the floating feeding mounting frame is fixed with a first floating cylinder. The output end of the first floating cylinder is connected to a first connector. The end of the first connector is hinged with a second connector. The second connector is rotatably mounted on the bottom of the floating feeding mounting frame. A through hole is provided in the middle of the second connector. An eccentric shaft is fitted in the through hole.

[0030] The bottom of the floating feeding mounting frame is provided with a downwardly extending protrusion, which contacts the outer circumferential surface of the eccentric shaft.

[0031] The first floating cylinder drives the second connector to reciprocate around the connection point between the second connector and the floating feeding mounting frame through the first connector, thereby driving the eccentric shaft to rotate. During the rotation of the eccentric shaft, the floating feeding mounting frame floats in the vertical direction through the protrusion.

[0032] The second support includes two symmetrically arranged support legs, and floating grooves are respectively provided on the opposite side walls of the two support legs. The floating feeding mounting frame is slidably installed between the two support legs through the floating grooves. A second floating cylinder is fixed to the outside of the second support. The output end of the second floating cylinder is connected to a connecting shaft. The connecting shaft passes through the wall of one support leg and is connected to the floating feeding mounting frame.

[0033] The second floating cylinder drives the connecting shaft to move linearly along the second horizontal direction, thereby causing the floating feeding mounting frame to float in the floating groove along the second horizontal direction.

[0034] The feeding slide rail is arranged along the first horizontal direction, and the clamping slide rail is arranged perpendicular to the feeding slide rail.

[0035] The structure of the feeding platform is as follows: it includes a support frame, several feeding rollers are mounted on the top of the support frame, a first connecting rod is rotatably mounted on the bottom of a single feeding roller, one end of a single first connecting rod is connected to one end of a second connecting rod, and the other end of a single second connecting rod is mounted on the outer circumferential surface of a drive shaft, and the drive shaft is rotatably mounted in the middle of the support frame.

[0036] A second connecting rod is connected to the output end of the tilting cylinder, which is fixed to the bracket.

[0037] The tail end of a single feeding roller table is provided with a U-shaped stop, and a stop block is installed on the top of the U-shaped stop;

[0038] Along the feeding direction, support rollers are respectively installed on both sides of the U-shaped stop at the top of the bracket;

[0039] When the tilting cylinder extends, it drives the drive shaft to rotate via the second connecting rod, which in turn drives the corresponding loading roller table to rotate via the first connecting rod, thereby causing the workpiece at the top of the loading roller table to roll into the U-shaped stop.

[0040] A material collection platform is installed on one side of the frame.

[0041] The frame is externally fitted with a cover.

[0042] The beneficial effects of this invention are as follows:

[0043] This invention features a compact and reasonable structure and is easy to operate. By incorporating a feeding device, a cutting device, a clamping device, and a floating feeding device, it can achieve fully automatic, high-precision, and non-destructive cutting of aluminum profiles, thereby enabling the workpiece to be cut into place in one go, effectively improving production efficiency, cutting quality, and ensuring product consistency.

[0044] The present invention also has the following advantages:

[0045] (1) In this invention, the cutting device is equipped with a V-belt, which has stable tension and high transmission accuracy. It can achieve high-precision transmission of the output torque of the cutting motor, thereby achieving precise and stable control of the saw blade speed, effectively improving the cutting accuracy and reducing the roughness of the workpiece cutting end face.

[0046] (2) In this invention, the clamping device can effectively limit the workpiece by setting two clamping cylinders arranged perpendicularly to each other and corresponding clamping seats, and can clamp the workpiece to prevent the workpiece from deviating, shaking, or being mispositioned during the cutting process, thereby ensuring that the perpendicularity and flatness of the cut end face of the workpiece after cutting meet the requirements of precision manufacturing.

[0047] (3) In this invention, the floating feeding device is equipped with a first floating cylinder, a first connector, a second connector, an eccentric shaft and a protrusion, so that the floating feeding mounting frame can float in the vertical direction, thereby making the clamping table slightly higher than the pressing table during the feeding process, preventing the pressing table from scratching the workpiece and protecting the workpiece's appearance.

[0048] (4) In this invention, the floating feeding device is equipped with a second floating cylinder, a connecting shaft and a floating groove, which enables the floating feeding mounting frame to float horizontally left and right. This allows the workpiece to deviate slightly from the clamping grid during the feeding process. During the retraction process after the floating feeding device finishes feeding, the clamping grid deviates slightly from the workpiece to prevent the clamping grid and the clamping grid from scratching the workpiece and to protect the workpiece's appearance from being flat.

[0049] (5) The present invention is equipped with an automatic control system, which has a continuous and compact production cycle, which can ensure rapid cutting and thus improve production efficiency. Attached Figure Description

[0069] The specific embodiments of the present invention will now be described with reference to the accompanying drawings.

[0070] The structure and function of this invention are as follows:

[0071] like Figures 1-13 As shown, a fully automatic high-precision cutting equipment specifically for aluminum profiles includes a feeding platform 6 for loading materials. A floating feeding device 5 is connected to the discharge end of the feeding platform 6, and a clamping cutting unit is connected to the rear end of the floating feeding device 5. Both the clamping cutting unit and the floating feeding device 5 are supported by a frame 4. This fully automatic high-precision cutting equipment achieves fully automatic production by setting up a clamping cutting unit, a frame 4, a floating feeding device 5, and a feeding platform 6. The equipment is also equipped with an automatic control system, a hydraulic system 8, and a maintenance-free lubrication system.

[0072] The automatic control system includes a PLC, an integrated operation panel, an electrical cabinet, a servo system, a hydraulic electrical control system, and a pneumatic electrical control system. The integrated operation panel is mounted on the frame 4, and buttons on the panel can be used to control various functions of the equipment. The remaining electrical control systems are centrally installed in the electrical control cabinet, which is fixed to one side of the frame 4. The automatic control system connects and combines the various parts through the PLC. Its control method is simple, reliable, and has a fast response, which can ensure superior equipment performance and a compact and continuous production cycle, thereby improving production efficiency.

[0073] Hydraulic system 8 is used to control the movement of each cylinder in the equipment to ensure the reliability of the floating feeding device 5 and related structures in the clamping and cutting unit;

[0074] The maintenance-free lubrication system includes self-lubricating components in each moving mechanism, which can complete the self-lubrication of each moving mechanism, thereby avoiding frequent downtime due to the need to add lubricating oil to each moving mechanism, saving equipment maintenance time and improving production efficiency;

[0075] The working end of the floating feeding device 5 clamps the workpiece 7 on the top of the feeding platform 6 and drives the workpiece 7 to move linearly along the first horizontal direction, thereby transporting the workpiece 7 to the feeding end of the pressing and cutting unit; the pressing and cutting unit includes a cutting device 2 for cutting the workpiece 7 and a pressing device 3 for pressing the workpiece 7. The bottom of the cutting device 2 is fitted with a feeding device 1, which drives the cutting device 2 to move linearly along the second horizontal direction, thereby cutting the workpiece 7 pressed by the working end of the pressing device 3; the first horizontal direction and the second horizontal direction are two directions perpendicular to each other on the horizontal plane;

[0076] The working end of the floating feeder 5, namely the working end face of the clamping table 507, the working end face of the clamping grid 512, and the working end face of the clamping seat 511, forms the clamping end for clamping the workpiece 7.

[0077] The feeding end of the clamping and cutting unit is the clamping table 302 of the clamping device 3, and the floating feeding device 5 transports the workpiece 7 onto the clamping table 302.

[0078] like Figures 4-5 As shown, in this invention, the feeding device 1 is used to drive the cutting device 2 to move linearly in the horizontal direction, so that the saw blade 208 in the cutting device 2 moves closer to or further away from the workpiece 7, so as to cut the workpiece 7.

[0079] Among them, such as Figure 4 As shown, the structure of the feeding device 1 is as follows: it includes a feeding mounting frame 101, several parallel feeding slide rails 103 are fixed on the top of the feeding mounting frame 101, several feeding sliders 104 are installed on the top of each feeding slide rail 103, and a cutting device 2 is installed on the top of each feeding slider 104.

[0080] A feed motor 102 is fixed to one side of the feed mounting bracket 101. The output end of the feed motor 102 is connected to the feed lead screw 107. The feed lead screw 107 is arranged parallel to the feed slide rail 103. A feed connecting seat 106 is installed on the outer circumference of the feed lead screw 107 through a feed nut 105. The feed connecting seat 106 is used to connect the cutting device 2 and is fixed to the bottom of the cutting device 2. The feed motor 102 drives the feed lead screw 107 to rotate, thereby causing the feed connecting seat 106 to move linearly along the axial direction of the feed lead screw 107 through the feed nut 105, which in turn drives the cutting device 2 to move linearly along the feed slide rail 103.

[0081] like Figure 5 As shown, the structure of the cutting device 2 is as follows: it includes a cutting mounting frame 201, a cutting motor 202 is fixed on the top of the cutting mounting frame 201, and the output end of the cutting motor 202 is connected to the drive pulley 203; a main shaft 206 is rotatably mounted on the cutting mounting frame 201 below the cutting motor 202 via a bearing 207, a driven pulley 204 is fixed to one end of the main shaft 206, the driven pulley 204 is located below the drive pulley 203, and a V-belt 205 is fitted between the driven pulley 204 and the drive pulley 203; a saw blade 208 is fixed to the other end of the main shaft 206, and one end of the saw blade 208 extends to the outside of the cutting mounting frame 201; the cutting motor 202 drives the drive pulley 203 to rotate, thereby driving the driven pulley 204 to rotate via the V-belt 205, and the driven pulley 204 drives the saw blade 208 to rotate via the main shaft 206, thereby causing the saw blade 208 to cut the workpiece 7;

[0082] In this invention, the cutting device 2 uses a V-belt 205, which has stable tension and high transmission accuracy, enabling high-precision transmission of the output torque of the cutting motor 202 and precise and stable control of the rotation speed of the saw blade 208.

[0083] like Figures 6-7 As shown, the clamping device 3 is used to clamp and limit the workpiece 7 when the cutting device 2 cuts the workpiece 7.

[0084] The structure of the clamping device 3 is as follows: it includes a clamping mounting frame 301, a first clamping cylinder 303 is fixed on the top of the clamping mounting frame 301, the output end of the first clamping cylinder 303 is connected to a first clamping seat 305, a clamping table 302 is fixed on the clamping mounting frame 301 below the first clamping seat 305, the working end face of the clamping table 302 is flat, a clamping grid 307 is fixed on the clamping mounting frame 301 on one side of the clamping table 302, the working end face of the clamping grid 307 is flat, the clamping grid 307 is arranged higher than the clamping table 302, so that the working end face of the clamping grid 307 and the working end face of the clamping table 302 form an L-shaped first limiting end face, thereby limiting the workpiece 7. Both the working end face of the clamping grid 307 and the working end face of the clamping table 302 have clearance grooves 308.

[0085] The working end faces of the first clamping seat 305 and the second clamping seat 306 are both flat. The working end faces of the first clamping seat 305 and the second clamping seat 306 and the first limiting end face form four-way limiting of the workpiece 7, thereby clamping the workpiece 7 when the cutting device 2 cuts it.

[0086] The clearance groove 308 can provide working space for the saw blade 208, and at the same time, it can position the saw blade 208 to prevent the saw blade 208 from shaking significantly and ensure cutting accuracy.

[0087] To ensure the clamping effect, the top of the clamping grid 307 needs to be higher than the center point of the workpiece 7, and the arrangement of the first clamping cylinder 303 and the first clamping seat 305 should be biased towards the clamping grid 307, so as to ensure that the center of the first clamping seat 305 is as close as possible to the center of the workpiece 7.

[0088] The second clamping cylinder 304 is fixed on the other side of the clamping mounting bracket 301. The output end of the second clamping cylinder 304 is connected to the second clamping seat 306, which faces the working end face of the clamping grid 307. The first clamping cylinder 303 drives the first clamping seat 305 to move in a straight line along the vertical direction, approaching or moving away from the working end face of the clamping table 302. At the same time, the second clamping cylinder 304 drives the second clamping seat 306 to move in a straight line along the horizontal direction, approaching or moving away from the working end face of the clamping grid 307, thereby clamping or releasing the workpiece 7 on the first limiting end face.

[0089] like Figure 7 As shown, in this invention, workpiece 7 is an aluminum rod in the shape of a cube or cylinder. At the same time, the equipment of this invention can also be applied to aluminum rods of various sizes and specifications, with a wide range of applications and strong practicality.

[0090] like Figures 8-11As shown, the floating feeding device 5 is used to transport the workpiece 7 on the loading platform 6 to the pressing table 302 of the pressing device 3. The cutting size of the workpiece 7 by the equipment is determined by the conveying distance of the floating feeding device 5.

[0091] The floating feeding device 5 is equipped with a first floating cylinder 516 and a second floating cylinder 517. The floating feeding device 5 floats vertically through the first floating cylinder 516, so that the horizontal working end face of the floating feeding device 5 is higher than the horizontal working end face of the pressing device 3. The floating feeding device 5 floats horizontally in the second direction through the second floating cylinder 517, so that the vertical working end face of the floating feeding device 5 is offset relative to the vertical working end face of the pressing device 3 in the second horizontal direction.

[0092] The horizontal working end face of the floating feeding device 5 is the clamping table 507, and the horizontal working end face of the pressing device 3 is the pressing table 302 of the pressing device 3; the vertical working end face of the floating feeding device 5 is the working end face of the clamping grid 512, and the vertical working end face of the pressing device 3 is the working end face of the pressing grid 307.

[0093] like Figure 8 As shown, the floating feeding device 5 has the following structure: it includes a floating feeding mounting frame 501, the bottom of which is supported by a first support 514 and a second support 515. A feeding motor 503 is fixed on one side of the floating feeding mounting frame 501. The output end of the feeding motor 503 is connected to a feeding screw 502. A slide block 506 is fitted on the outer circumference of the feeding screw 502. Several feeding sliders 505 are fitted on the bottom of the slide block 506. The feeding sliders 505 are fitted with several corresponding feeding slide rails 504. The several feeding slide rails 504 are fixed parallel to the top of the floating feeding mounting frame 501. The feeding motor 503 drives the feeding screw 502 to rotate, thereby causing the slide block 506 to move linearly along the feeding slide rails 504.

[0094] A clamping table 507 is provided on the top of the slide 506. The working end face of the clamping table 507 is flat. Several parallel clamping slide rails 508 are fixed on the top of the slide 506 next to the clamping table 507. A clamping slider 509 is installed on each clamping slide rail 508. A clamping seat 511 is fixed on the top of the clamping slider 509. The clamping seat 511 is connected to the output end of the clamping cylinder 510. A clamping grid 512 is provided on the opposite side of the clamping seat 511. The clamping grid 512 is fixed on one side of the slide 506. The working end face of the clamping grid 512 is flat. At the same time, the working end face of the clamping grid 512 is higher than the working end face of the clamping table 507, thus forming an L-shaped second limiting end face. The second limiting end face limits the workpiece 7.

[0095] The working end face of the clamping seat 511 is flat. The clamping cylinder 510 drives the clamping seat 511 to make a linear movement along the clamping slide rail 508 to approach or move away from the working end face of the clamping grid 512, thereby clamping or releasing the workpiece 7 on the second limit end face.

[0096] The feeding slide rail 504 is arranged along the first horizontal direction, and the clamping slide rail 508 is arranged perpendicular to the feeding slide rail 504.

[0097] An auxiliary roller 513 is installed on one side of the slide block 506. The top outer contour of the auxiliary roller 513 is flush with the working end face of the clamping table 507. The auxiliary roller 513 is used to provide auxiliary support for the workpiece 7 to prevent the workpiece 7 from being deformed or scratched due to excessive transport distance.

[0098] like Figures 9-10 As shown, the floating feeding device 5 has the ability to float in the vertical direction. The bottom of the floating feeding mounting frame 501 is fixed with a first floating cylinder 516. The output end of the first floating cylinder 516 is connected to a first connector 518. The end of the first connector 518 is hinged with a second connector 519. The second connector 519 is rotatably mounted on the bottom of the floating feeding mounting frame 501. A through hole is provided in the middle of the second connector 519, and an eccentric shaft 521 is fitted in the through hole. The bottom of the floating feeding mounting frame 501 is provided with a downwardly extending protrusion 520, which contacts the outer circumferential surface of the eccentric shaft 521.

[0099] The first floating cylinder 516 drives the second connector 519 to reciprocate around the connection point between the second connector 519 and the floating feeding mounting frame 501 via the first connector 518, thereby driving the eccentric shaft 521 to rotate. During the rotation of the eccentric shaft 521, the floating feeding mounting frame 501 floats vertically through the protrusion 520, which allows the clamping table 507 to be slightly higher than the pressing table 302 during the feeding process. This prevents the pressing table 302 from scratching the workpiece 7 when the floating feeding device 5 feeds the workpiece 7 onto the pressing table 302, thus protecting the smooth appearance of the workpiece 7.

[0100] like Figure 11 As shown, the floating feeding device 5 has the ability to float along the second horizontal direction. The second support 515 includes two symmetrically arranged support legs. Floating grooves 523 are respectively provided on the opposite side walls of the two support legs. The floating feeding mounting frame 501 is slidably mounted between the two support legs through the floating grooves 523. A second floating cylinder 517 is fixed to the outside of the second support 515. The output end of the second floating cylinder 517 is connected to a connecting shaft 522. The connecting shaft 522 passes through the wall of one support leg and is connected to the floating feeding mounting frame 501. The second floating cylinder 517 drives the connecting shaft 522 to move linearly along the second horizontal direction, thereby causing the floating feeding mounting frame 501 to float in the floating grooves 523 along the second horizontal direction.

[0101] During the feeding process, the second floating cylinder 517 extends along the feeding direction and drives the floating feeding mounting frame 501 to move forward in a straight line along the second horizontal direction via the connecting shaft 522. This causes the clamping grid 512 to deviate slightly to the left relative to the pressing grid 307, so that the workpiece 7 deviates slightly from the pressing grid 307. This prevents the pressing grid 307 from scratching the workpiece 7 when the floating feeding device 5 feeds the workpiece 7 onto the pressing table 302, thus protecting the smooth appearance of the workpiece 7.

[0102] During the retraction process after feeding, the second floating cylinder 517 retracts along the feeding direction and drives the floating feeding mounting frame 501 to move backward in a straight line along the second horizontal direction via the connecting shaft 522. This causes the clamping grid 512 to deviate slightly to the right relative to the pressing grid 307, thus slightly deviating the clamping grid 512 from the workpiece 7. This prevents the clamping grid 512 from scratching the workpiece 7 during the retraction process of the floating feeding device 5, and protects the smooth appearance of the workpiece 7.

[0103] like Figures 12-13 As shown, the feeding platform 6 is used for automatic feeding. The structure of the feeding platform 6 is as follows: it includes a support 601, several feeding roller tables 602 are mounted on the top of the support 601, a first connecting rod 604 is rotatably mounted on the bottom of each feeding roller table 602, one end of the first connecting rod 604 is connected to one end of a second connecting rod 605, and the other end of the second connecting rod 605 is mounted on the outer circumferential surface of a drive shaft 609, which is rotatably mounted in the middle of the support 601; one second connecting rod 605 is connected to the output end of a tilting cylinder 603, which is fixed on the support 601.

[0104] A U-shaped stop 606 is provided at the tail end of a single feeding roller table 602. A stop block 607 is installed on the top of the U-shaped stop 606. The stop block 607 can ensure that the workpiece 7 falls into the U-shaped stop 606 and prevent the workpiece 7 from falling out during the process of rolling from the top of the feeding roller table 602 into the U-shaped stop 606.

[0105] Along the feeding direction, support rollers 608 are respectively installed on both sides of the U-shaped stop 606 at the top of the bracket 601; the support rollers 608 assist in supporting the workpiece 7, and at the same time ensure the movement stability of the workpiece 7 during the feeding process.

[0106] When the tilting cylinder 603 extends, it drives the drive shaft 609 to rotate via the second connecting rod 605, which in turn drives the corresponding loading roller table 602 to flip via the first connecting rod 604, thereby causing the workpiece 7 on the top of the loading roller table 602 to roll into the U-shaped stop 606.

[0107] The loading platform 6 achieves the flipping of the loading roller table 602 through the first connecting rod 604 and the second connecting rod 605, so that the workpiece 7 on the top of the loading roller table 602 falls into the U-shaped stop 606 to achieve automatic loading.

[0108] A material collection platform 9 is installed on one side of the frame 4 to collect the workpieces 7 that have been cut and processed; a cover is installed on the outside of the frame 4 to protect the feeding device 1, the cutting device 2, the clamping device 3 and the floating feeding device 5.

[0109] The working process of this invention is as follows:

[0110] S1. Loading: The worker places the workpiece 7 on the top of the loading table 6, and the loading table 6 transports the workpiece 7 to the set position;

[0111] S2. Floating feeding device 5 clamps and transports workpiece 7: clamping cylinder 510 extends, causing floating feeding device 5 to clamp workpiece 7, first floating cylinder 516 extends, causing floating feeding device 5 to float in the vertical direction, feeding motor 503 starts, causing floating feeding device 5 to move forward in the first horizontal direction, transporting workpiece 7 to clamping device 3.

[0112] S3. Pressing device 3 presses workpiece 7: After the floating feeding device 5 transports workpiece 7 to the position, the first floating cylinder 516 retracts, causing the floating feeding device 5 to fall vertically. Then the first pressing cylinder 303 and the second pressing cylinder 304 extend simultaneously, causing the pressing device 3 to press workpiece 7. Then the clamping cylinder 510 retracts, causing the floating feeding device 5 to release workpiece 7.

[0113] At the same time, the cutting motor 202 starts, the saw blade 208 cuts the workpiece 7, and the floating feeding device 5 returns to the initial position;

[0114] After the cutting is completed, the floating feeder 5 clamps the workpiece 7 again, and then the clamping device 3 releases the workpiece 7.

[0115] S4. Material Removal: After the cutting is completed, the next cutting is carried out until the cut workpiece 7 is pushed out to the collection table 9 by the subsequent workpiece 7, and then the material can be manually removed.

[0116] The above description is an explanation of the present invention and not a limitation thereof. The scope of the present invention is defined by the claims. Within the scope of protection of the present invention, any form of modification may be made.
