Description

Technical Field

[0001] This invention relates to the field of steel drilling and cutting technology, and in particular to a drilling and cutting device for steel processing. Background Technology

[0002] In the steel processing industry, plate drilling and cutting are two core basic processes, widely used in construction, machinery manufacturing, automobiles, shipbuilding, and many other fields. Currently, as the steel industry enters a new stage of "reduction and adjustment, stock optimization, and quality improvement and upgrading," downstream manufacturing industries are placing higher demands on the precision, efficiency, and finished product quality of steel processing. Traditional steel drilling and cutting equipment is no longer adequate to meet the industry's development needs, gradually revealing many problems that require solutions.

[0003] In the drilling process, traditional equipment lacks effective support and protection structures around the drilling area of ​​the sheet metal. The impact force generated during drilling can easily cause problems such as collapse, cracking, and deformation at the drilling point. Furthermore, the hole diameter is prone to deviation and excessive burrs, making it difficult to guarantee the forming quality. This not only increases the probability of workpiece scrap and rework but also raises processing costs. At the same time, the sheet metal after cutting relies on non-automatic unloading methods. This method not only prolongs the process interval time, causing the processing flow to be inconsistent and resulting in low overall processing efficiency, but also easily causes the sheet metal to be bumped, scratched, bent, and deformed during non-automatic unloading, seriously affecting the quality of the finished sheet metal. These problems are even more prominent for steel used in manufacturing industries with high precision requirements. Summary of the Invention

[0004] To overcome the shortcomings of the prior art, the present invention is achieved through the following technical solution:

The outer wall of the ball fits against the top of the lifting bar. The outer wall of the connecting rod fits against the groove opened in the lifting bar.

[0007] The drive assembly includes a first fixed frame, the bottom of which is fixedly connected to the top of the support frame. A first threaded rod is rotatably connected to the inner wall of the first fixed frame. A second fixed frame is threadedly connected to the outer wall of the first threaded rod.

A fourth threaded rod is rotatably connected to the inner wall of the fourth fixed frame. A first slide rail is fixedly connected to the top of the base. The first slide rail is detachably connected to a second slide rail via an internally installed flat linear motor. By setting up the drive assembly, the drilling and cutting positions of the sheet metal can be adjusted, thereby enabling multi-position processing to be completed in a single clamping, eliminating repeated disassembly and positioning, and improving processing efficiency.

[0008] The drilling assembly includes a first mounting frame, which is threadedly connected to the outer wall of a second threaded rod. A first electro-hydraulic rod is detachably connected to the inner wall of the first mounting frame. A first mounting plate is fixedly connected to the telescopic end of the first electro-hydraulic rod. A drill is detachably connected to the bottom of the first mounting plate. A support block is threadedly connected to the outer wall of a fourth threaded rod. A collection tube is detachably connected to the bottom of the support block. A support strip is slidably connected to the top of the base via a groove. The support strip is slidably connected to the support block. By setting up the drilling assembly, holes can be drilled into the sheet metal, effectively preventing deformation of the sheet metal at the drilling point, avoiding collapse, cracking, and excessive burrs during drilling, and improving the drilling quality and hole diameter accuracy. At the same time, it disperses the drilling impact force, reduces sheet metal vibration and shaking, and makes processing more stable.

[0009] The base is detachably connected to a first motor via an ear plate on its outer wall. A first transmission wheel is fixedly connected to one end of the third threaded rod outside the third fixed frame.

A fourth transmission wheel is fixedly connected to one end of the second threaded rod outside the second fixed frame. The fourth transmission wheel is driven through the second transmission belt. By setting up the first motor, first transmission wheel, first transmission belt, second transmission wheel, second motor, third transmission wheel, second transmission belt, and fourth transmission wheel, the positions of the punch and the support block can be synchronously adjusted, facilitating drilling of the sheet metal and providing support for the areas where drilling is needed.

[0010] The cutting assembly includes a second mounting frame. The top of the second mounting frame is detachably connected to the bottom of the second slide rail via a flat linear motor. A second electro-hydraulic rod is detachably connected inside the second mounting frame. A second mounting plate is fixedly connected to the telescopic end of the second electro-hydraulic rod. A cutter is detachably connected to the bottom of the second mounting plate. By setting up the cutting assembly, the sheet metal can be cut, and the cutting area of ​​the sheet metal can be supported during cutting, effectively preventing warping and deformation of the sheet metal during cutting, improving cutting flatness and dimensional accuracy, reducing cutting gap deviation, and distributing cutting force to reduce sheet metal vibration, making operation more stable, and reducing workpiece scrap and rework.

[0011] A first limiting rod is fixedly connected to the top of the first mounting plate, and the first limiting rod is slidably connected to the first mounting frame. A second limiting rod is fixedly connected to the top of the second mounting plate, and the second limiting rod is slidably connected to the second mounting frame. By setting the first limiting rod and the second limiting rod, the cutter and the punch are limited, preventing the cutter and the punch from shaking during use, thereby avoiding affecting the cutting and cutting of the board by the cutter and the punch.

[0012] The fourth threaded rod is fixedly connected to a telescopic sleeve rod, and the telescopic end of the telescopic sleeve rod is fixedly connected to a lower pressure plate. The bottom of the second mounting plate is fixedly connected to a second spring telescopic rod, and the telescopic end of the second spring telescopic rod is fixedly connected to a pressing plate. The bottom of the pressing plate is slidably connected to the top of the lower pressure plate. The bottom of the first mounting plate is fixedly connected to a first spring telescopic rod. By setting the telescopic sleeve rod, the lower pressure plate, the second spring telescopic rod, the pressing plate, and the first spring telescopic rod, the surrounding sheet metal is pressed during drilling and cutting, thereby effectively suppressing the shaking of the sheet metal and avoiding the displacement of the sheet metal during processing, which would cause the hole position to shift or the cut to become skewed.

[0014] The feeding assembly includes an electric push rod, the outer wall of which is detachably connected to the top of the base. A movable frame is fixedly connected to the telescopic end of the electric push rod, and an electric telescopic rod is fixedly connected to the top of the movable frame. A clamping plate is fixedly connected to the telescopic end of the electric telescopic rod. By setting up the feeding assembly, the sheet metal is clamped and pushed, realizing automatic feeding of the sheet metal without the need for manual pushing and alignment. The clamping and limiting are firm, which can prevent the sheet metal from deviating or running off course during transportation, ensuring accurate feeding position at the drilling and cutting stations and high consistency of processing dimensions.

[0015] The beneficial effects of this invention are as follows:

[0016] 1. By setting up the unloading component, when the cutter moves along the second slide rail, it can drive the sliding connecting rod to move. Then, through the cooperation of the ball, lifting plate and lifting bar, the flipping plate is flipped, thereby realizing the automatic unloading of the board after cutting. The automatic unloading of the board after cutting can reduce the collision, scratches and bending deformation during the transportation process, ensuring the quality of the finished board. At the same time, it can form a continuous operation process with the drilling and cutting processes, eliminating the need to wait for transfer and shortening the process interval time.

[0017] 2. By setting up a drilling component, holes can be drilled into the board, effectively preventing deformation of the board at the drilling point, avoiding collapse, cracking and excessive burrs during drilling, and improving the drilling quality and hole diameter accuracy; at the same time, it disperses the drilling impact force, reduces board vibration and shaking, and makes processing more stable.

[0018] 3. By setting up the cutting components, the sheet metal can be cut, and the cutting area of ​​the sheet metal can be supported during the cutting process, which can effectively prevent the sheet metal from warping and deforming during the cutting process, improve the flatness and dimensional accuracy of the cutting, reduce the deviation of the cutting gap, and at the same time, it can distribute the cutting force, reduce the vibration of the sheet metal, run more smoothly, and reduce the scrap and rework of the workpiece.

[0019] 4. By setting up a feeding component, the system achieves automatic feeding of the sheet metal, eliminating the need for manual pushing and alignment. The secure clamping and limiting mechanism prevents offset and deviation during sheet metal transport, ensuring precise feeding positions at drilling and cutting stations and high dimensional consistency. Simultaneously, the stable and uniform feeding speed reduces sheet metal shaking and jamming, making it suitable for continuous batch processing. This significantly improves work efficiency, reduces manual labor intensity, and avoids safety hazards associated with manual feeding, resulting in a marked improvement in the equipment's automation level and versatility.

The automation level and versatility of the equipment are significantly improved.

[0049] Working principle:

[0050] After the device is started, the electric push rod 701 drives the movable frame 702 to reciprocate along the base 1. The electric telescopic rod 703 at the top of the movable frame 702 drives the clamping plate 704 to move, realizing reliable clamping of the plate. Then, the electric push rod 701 drives the plate to be smoothly conveyed to the work station along the placement plate 8. After the plate is conveyed, the first motor 311 drives the second transmission wheel 314 to rotate through the first transmission wheel 312 and the first transmission belt 313, which drives the first threaded rod 302 to rotate, so that the threaded second fixed frame 303 moves horizontally along the first fixed frame 301. At the same time, the second motor 315 drives the fourth transmission wheel 318 through the third transmission wheel 316 and the second transmission belt 317. The rotation drives the fourth threaded rod 308 to rotate, causing the threaded drilling assembly 4 to move horizontally along the third fixed frame 305 and the fourth fixed frame 307. The first mounting frame 401 of the drilling assembly 4 is threadedly connected to the second threaded rod 304 and can move synchronously with the drive assembly 3. The first electric hydraulic rod 402 drives the first mounting plate 403 and the bottom drill 404 to feed downwards, realizing the drilling operation on the plate. During the operation, the support block 407 provides support around the drilling position. With the auxiliary limit of the support bar 409, the first spring telescopic rod 406 presses the periphery of the plate during drilling to suppress the vibration and shaking of the plate and reduce the workpiece movement caused by the drilling impact force.

[0051] After the plate is drilled, the second mounting frame 501 of the cutting assembly 5 is connected to the second slide rail 310, enabling precise adjustment of the cutting position. The second electric hydraulic rod 502 drives the second mounting plate 503 and the bottom cutter 504 to feed downwards to cut the plate. The second limit rod 505 guides and limits the cutter 504 to prevent the equipment from shaking during the cutting process, which would affect the cutting accuracy and tool life. At the same time, the second spring telescopic rod 513 drives the pressing plate 514 to move downwards, cooperating with the lower pressure plate 507. The lower pressure plate 507 is linked with the support plate 512 through the first round rod 508, the first connecting strip 509, the second round rod 510, and the second connecting strip 511, so that the support plate 512 is always located directly below the cutter 504, directly supporting the plate cutting position, distributing the cutting force, and preventing the plate from sagging and deforming during cutting.

[0052] After cutting, the sliding frame 601 is slidably connected to the groove of the base 1. The internally rotatably connected flip plate 602, in its initial state, together with the support plate 512, forms the support surface of the plate. During unloading, the connecting rod 603 moves upward under the drive of the lifting plate 605. The ball 604 on the outer wall of the connecting rod 603 slides along the guide groove of the lifting bar 606, causing the connecting rod 603 to move synchronously, so that the flip plate 602 flips downward around the rotation axis of the sliding frame 601. After the plate loses its support, it automatically slides down, realizing automatic unloading without manual intervention.
