Description

Technical Field

[0001] This invention relates to the field of grooving machine technology, and in particular to a grooving machine for processing prebaked anode carbon blocks. Background Technology

[0002] Prebaked anode carbon blocks are commonly used block raw materials in industrial production such as electrolytic aluminum. Before subsequent use, they usually need to be processed at the bottom to form straight grooves, inclined grooves, or blind grooves according to process requirements to meet installation, flow guidance, or other matching needs. Since the anode carbon blocks are large in size and heavy in weight, and the length, width, height, and groove depth requirements of carbon blocks of different batches and specifications vary, high requirements are placed on the clamping stability of the grooving equipment, the ability to adjust the grooving position, and the adaptability to carbon blocks of different specifications.

[0003] Most existing anode carbon block grooving equipment uses circular saw-like tools to cut the bottom of the carbon block. Since anode carbon blocks are brittle block materials, during the circular saw cutting in and out, chipping, corner breaking, or even micro-cracks are easily generated on both sides of the groove, especially at the end, which affects the processing quality and the consistency of the finished product. A large amount of dust, particulate matter, and granular material are generated during the grooving process, which can easily cause chip accumulation on the surface of the saw blade and in the groove, thus affecting the cutting stability.

[0004] Therefore, it is necessary to provide a grooving machine for processing prebaked anode carbon blocks to solve the problems of easy chipping of the groove opening and chip accumulation in the cutting zone in the prior art. Summary of the Invention

[0005] The purpose of this invention is to provide a grooving machine for processing prebaked anode carbon blocks, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a grooving machine for processing prebaked anode carbon blocks, comprising: The main frame has two symmetrical tracks fixedly installed at its top. One end of the main frame along the feeding direction of the anode carbon block is the feed end, and the other end is the discharge end. A dust collection hood is slidably mounted above two tracks. Clamping seats are installed on both inner walls of the dust collection hood. The dust collection hood and the clamping seats together form a clamping mechanism for the anode carbon block. A tool support is installed inside the main frame and located between two tracks. A movable seat is installed inside the tool support and can slide up and down. A circular saw is rotatably installed on the middle of one side of the movable seat. The movable seat and the circular saw together form a lifting grooving mechanism. The anti-scraping edge support is provided in two parts, which are located on both sides of the circular saw. The ends of the upper surfaces of the two anti-scraping edge supports away from the dust collection hood are jointly installed with end face supports with a "∩" shaped cross section. The anti-scraping edge support and the end face support together form an anti-scraping edge mechanism for fitting with the groove opening of the anode carbon block during the grooving process.

[0007] Preferably, it also includes a horizontal slide, which is located at the top of the tool support and below the two anti-scraping supports. Both ends of the lower surface of the two anti-scraping supports are movably mounted with movable arms by means of pins, and the bottom end of the movable arms is movably connected to the inner side wall of the horizontal slide by means of pins. The movable arms, the anti-scraping supports and the horizontal slide together form a four-bar linkage mechanism for controlling the lifting and lowering of the anti-scraping supports. The lifting motor is fixedly installed on the outside of the horizontal slide, and the output shaft of the lifting motor is fixedly connected to the bottom end of a movable arm.

A cylinder support is fixedly installed on the top of the side of the tool support near the discharge end of the main frame, and a reset cylinder is fixedly installed on the top of the cylinder support. A cylinder connecting seat is fixedly installed on the lower surface of the guide seat and has a through hole in the middle. A cylinder connecting rod is slidably installed inside the hole. One end of the cylinder connecting rod is fixedly connected to the output end of the reset cylinder. A buffer spring is installed around the outer surface of the cylinder connecting rod, and the buffer spring is located between the output end of the reset cylinder and the outer surface of the cylinder connecting seat.

[0009] Preferably, it also includes an air guide seat, which is fixedly installed on the bottom end of the anti-scraping edge support near the circular saw. A strip-shaped air groove is provided through the middle of the air guide seat. Multiple equally spaced inclined mounting seats are fixedly installed on the side of the air guide seat away from the circular saw. An air nozzle is installed through the middle of each of the multiple inclined mounting seats, and one end of the air nozzle is connected to the strip-shaped air groove. The air nozzle, the inclined mounting seat and the strip-shaped air groove together form an air guiding mechanism that guides compressed air to the surface of the circular saw and the groove of the anode carbon block.

[0010] Preferably, it also includes a wing plate, which is fixedly installed on the side of the air guide seat near the circular saw and located at the bottom end of the slot of the strip air groove, and the cross section of the wing plate is an upward inclined structure.

[0011] Preferably, it also includes a lifting lead screw, which is movably mounted on the bottom center of the tool support via a bearing. A lead screw sleeve adapted to the lifting lead screw is fixedly mounted on the bottom of the movable seat. A lead screw motor is fixedly mounted on the bottom of the tool support. The output shaft of the lead screw motor is connected to the bottom of the lifting lead screw. The lead screw motor, the lifting lead screw, and the lead screw sleeve together form the movable seat and the lifting mechanism of the circular saw.

[0012] Preferably, it also includes a horizontal slide, which is fixedly installed at the bottom end of the tool support; The horizontal slide rail is fixedly installed at the bottom of the main frame, and the horizontal slide table is slidably installed above the horizontal slide rail. The horizontal slide table and the horizontal slide rail together form the tool support, the movable seat, and the horizontal adjustment mechanism of the circular saw.

[0013] Preferably, a clamping cylinder is fixedly installed between the clamp and the dust collection hood.

[0014] Preferably, a clamping plate is fixedly installed on the bottom end of the clamping seat on the side away from the inner wall of the dust collection hood, and multiple anti-slip protrusions are fixedly installed on the side of the clamping plate away from the clamping seat.

[0015] Preferably, the discharge end of the main frame is equipped with a roller conveyor chain, and the roller conveyor chain is set as an inclined structure and located between two tracks.

[0016] The technical effects and advantages of this invention are as follows: 1. This invention sets anti-chipping supports on both sides of a circular saw and connects the two anti-chipping supports with "∩"-shaped end face supports to form an anti-chipping mechanism. This mechanism fits into the groove opening of the anode carbon block during the grooving process, thereby providing support and constraint to the area adjacent to the groove opening. This helps to reduce the chipping, corner breaking, and crack propagation problems that occur when the anode carbon block, as a brittle block material, is cut in and out. The four-bar lifting structure, consisting of a movable arm, a horizontal slide, and a lifting motor, enables the anti-chipping supports to lift stably and fit reliably. Combined with a guide seat, a reset cylinder, a cylinder connecting rod, and a buffer spring, a guide reset buffer structure is formed, giving the anti-chipping mechanism a certain degree of flexibility and adaptability, avoiding rigid collisions, thereby further preventing chipping at the groove opening of the anode carbon block during the grooving process and ensuring the stability of the grooving quality. 2. This invention integrates an air guide seat, a strip-shaped air groove, an inclined mounting seat, an air nozzle, and a wing plate on the anti-chipping edge support, enabling compressed air to be guided to the surface of the circular saw and the groove. Furthermore, the combination of the air guide seat and the anti-chipping edge support forms a directional guiding mechanism for compressed air, effectively ensuring that compressed air can simultaneously blow away chips from the saw blade surface and the groove, thereby further improving the cleaning effect of the cutting area and ensuring the stability of the grooving quality. 3. This invention features a tool support inside the main frame, with a movable seat that can slide up and down within the tool support. A circular saw is mounted on the movable seat, creating a lifting and lowering grooving mechanism. The lifting mechanism is formed by a lifting screw, screw sleeve, and screw motor, while the horizontal adjustment mechanism is formed by a horizontal slide table and horizontal slide rail. This allows the circular saw to adjust not only the groove depth in the vertical direction but also the groove position in the horizontal direction. This adapts to different groove types, such as straight grooves, inclined grooves, and blind grooves, as well as different groove depths and positions on anode carbon blocks, improving the equipment's adaptability to carbon blocks of different specifications and processing parameters.

[0028] 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.

[0029] like Figures 1 to 10 As shown, the grooving machine for processing prebaked anode carbon blocks provided by the present invention is essentially a grooving machine that can solve the problems of easy chipping of the groove opening and chip accumulation in the cutting zone in the prior art.

[0030] In terms of specific structural installation, the structural body can be constructed according to the inventive concept of this embodiment. In this embodiment, no special limitations are imposed.

[0031] In this embodiment, a grooving machine for processing prebaked anode carbon blocks includes: The main frame 1 is preferably constructed from Q235A or Q355B steel plates and welded structural steel to form a portal or box-type load-bearing frame. Two symmetrical rails are fixedly installed at its top. These rails are preferably precision-machined heavy-duty linear guides or guide rail pairs, with toothed grooves on their upper surfaces for engagement with internal gears in the dust collection hood 2 to drive it. They are fixed to both sides of the top of the main frame 1 with high-strength bolts to ensure the guiding accuracy and operational stability of the dust collection hood 2 during reciprocating movement. One end of the main frame 1 along the anode carbon block feeding direction... One end is the feeding end, and the other end is the discharging end. The discharging end of the main frame 1 is equipped with a roller conveyor chain 11. The roller conveyor chain 11 is preferably composed of a sprocket, a conveyor chain, multiple equally spaced supporting rollers and a drive assembly. The whole structure is inclined along the feeding direction with the front low and the back high or the back low and the front high, so that the anode carbon block can stably enter the clamping and grooving station under the combined action of its own weight and the conveying driving force. The roller conveyor chain 11 is located between two tracks, thus forming a feeding and processing channel with the upper dust collection hood 2 and the lower tool support 3. The dust collection hood 2 is preferably formed by bending and welding steel plates to create a hood structure that is closed at the top and open at the bottom. It is slidably installed above two tracks. The dust collection hood 2 has gears inside that mesh with the toothed grooves on the track surface. The gears are equipped with a transmission chain and a motor to form the drive structure of the dust collection hood 2. The top or side of the dust collection hood 2 can be connected to an external dust collection pipeline. Both inner walls of the dust collection hood 2 are equipped with clamps 21. The dust collection hood 2 and the clamps 21 together form the clamping mechanism for the anode carbon block. A clamping cylinder is fixedly installed between the clamps 21 and the dust collection hood 2. A clamping plate 211 is fixedly installed at the bottom of the side of the clamps 21 away from the inner wall of the dust collection hood 2. Multiple anti-slip protrusions are fixedly installed on the side of the clamps 211 away from the clamps 21. The multiple anti-slip protrusions are preferably hemispherical, frustum-shaped, or strip-shaped and are evenly distributed on the outer surface of the clamps 211 to improve the clamping friction and prevent the carbon block from slipping during the cutting vibration. The tool support 3 is installed inside the main frame 1 and located between two rails. The tool support 3 has a movable seat 311 that can slide up and down inside. Vertical guide grooves, wear-resistant sliders or linear guide pairs can be provided on both sides of the tool support 3 to guide and limit the lifting and lowering movement of the movable seat 311. A circular saw 31 is rotatably installed in the middle of one side of the movable seat 311. The circular saw 31 preferably includes a saw blade body, a saw blade pressure plate, a spindle and a transmission end connected to an external power device. The saw blade body can be made of an alloy matrix and a diamond cutting head is provided on the outer edge. The movable seat 311 and the circular saw 31 together constitute a lifting and lowering grooving mechanism, so that the circular saw 31 can adjust the cutting depth relative to the bottom of the anode carbon block to adapt to the processing requirements of different groove types such as straight grooves, inclined grooves and arc grooves. The lifting screw 313 is movably mounted at the bottom center of the tool support 3 via bearings. A screw sleeve adapted to the lifting screw 313 is fixedly mounted at the bottom of the movable seat 311. The screw sleeve adopts an integral nut seat or flange nut seat structure and is fixed to the bottom of the movable seat 311 by bolts or welding. A screw motor 314 is fixedly mounted at the bottom of the tool support 3. The output shaft of the screw motor 314 is drivenly connected to the bottom of the lifting screw 313. The output shaft of the screw motor 314 can be drivenly connected to the bottom of the lifting screw 313 via a coupling, synchronous belt pulley assembly or reduction transmission assembly. The screw motor 314, the lifting screw 313 and the screw sleeve together form the lifting mechanism of the movable seat 311 and the circular saw 31.

[0032] The horizontal slide 315 is fixedly installed at the bottom of the tool support 3. It is a plate slide, a linear module base, or a support platform structure with a mounting flange. The horizontal slide rail 316 is fixedly installed at the bottom of the main frame 1. It consists of two parallel heavy-duty guide rails, secondary rails, or dovetail slide rails, and is fixedly installed at the bottom of the main frame 1, allowing the horizontal slide table 315 to slide smoothly in the horizontal direction. The horizontal slide table 315 is slidably installed above the horizontal slide rail 316. The horizontal slide table 315 and the horizontal slide rail 316 together form the horizontal adjustment mechanism of the tool support 3, the movable seat 311, and the circular saw 31. This allows the entire tool assembly to be adjusted laterally according to different anode carbon block widths, slot requirements, and double-sided tool setting requirements. After adjustment, it can be locked by locking bolts, pressure plates, or positioning blocks to improve positional stability during the cutting process.

[0033] The anti-scraping support 4 is a plate-type support with a smooth surface. There are two of them, which are located on both sides of the circular saw 31. The ends of the upper surfaces of the two anti-scraping supports 4 away from the dust collection cover 2 are jointly equipped with end face supports 41 with a "∩" shaped cross section. The anti-scraping support 4 and the end face supports 41 together form an anti-scraping mechanism for fitting with the groove opening of the anode carbon block during the grooving process.

[0034] The horizontal slide 42 is located at the top of the tool support 3 and below the two anti-scraping supports 4. The two ends of the lower surface of the two anti-scraping supports 4 are movably mounted with movable arms 43 by pins, and the bottom end of the movable arms 43 is movably connected to the inner wall of the horizontal slide 42 by pins. The movable arms 43, the anti-scraping supports 4 and the horizontal slide 42 together form a four-bar linkage mechanism to control the lifting and lowering of the anti-scraping supports 4. The lifting motor 431 is fixedly installed on the outside of the horizontal slide 42, and the output shaft of the lifting motor 431 is fixedly connected to the bottom end of a movable arm 43. The lifting motor 431 is fixedly installed on the outside of the horizontal slide 42, and its output shaft is fixedly connected to the bottom end of one of the movable arms 43 through a reducer, so as to drive the movable arm 43 to swing and drive the entire four-bar linkage to move, thereby realizing the synchronous lifting of the two anti-collapse side supports 4.

[0035] The guide seat 44 is fixedly installed on the side of the horizontal slide 42 near the discharge end of the main frame 1. The bottom end of the guide seat 44 is fixedly installed with a guide slide 441, and the guide slide 441 is slidably installed on the top end of the tool support 3. The guide slide 441 is installed on the guide surface, guide groove or linear guide rail at the top end of the tool support 3. The cylinder support 442 is fixedly installed on the top of the side of the tool support 3 near the discharge end of the main frame 1, and a reset cylinder 443 is fixedly installed on the top of the cylinder support 442. The cylinder connecting seat 444 is fixedly installed on the lower surface of the guide seat 44 and has a through hole in the middle. The cylinder connecting rod 445 is slidably installed inside the hole. One end of the cylinder connecting rod 445 is fixedly connected to the output end of the reset cylinder 443. A buffer spring 446 is installed around the outer surface of the cylinder connecting rod 445. The buffer spring 446 is located between the output end of the reset cylinder 443 and the outer surface of the cylinder connecting seat 444. When the anti-scraping support 4 is close to the anode carbon block groove, the buffer spring 446 forms a certain elastic buffer stroke, which can reduce rigid collision and facilitate the anti-scraping mechanism to automatically rebound and reset after being pressed.

[0036] The air guide seat 401 is fixedly installed on the bottom end of the anti-chipping support 4 near the circular saw 31. A strip-shaped air groove 402 is provided through the middle of the air guide seat 401. The strip-shaped air groove 402 is used to evenly distribute external compressed air to multiple spray positions. Multiple equally spaced inclined mounting seats 403 are fixedly installed on the side of the air guide seat 401 away from the circular saw 31. Air nozzles 404 are installed through the middle of the multiple inclined mounting seats 403, and one end of the air nozzles 404 is connected to the strip-shaped air groove 402. The air nozzles 404, the inclined mounting seats 403 and the strip-shaped air groove 402 together form an air guide mechanism that guides compressed air to the surface of the circular saw 31 and the anode carbon block groove, so that the compressed air can be blown in a predetermined direction to the working surface of the circular saw 31 and the chip accumulation area in the groove, so as to clean the dust on the surface of the saw blade in time and blow the particles in the groove away from the cutting area.

[0037] The wing plate 405 is fixedly installed on the side of the air guide seat 401 near the circular saw 31 and located at the bottom end of the slot of the strip air groove 402. The cross-section of the wing plate 405 is an upward inclined structure, which allows the airflow ejected from the strip air groove 402 and the air nozzle 404 to flow more towards the outer circumferential surface of the circular saw 31, the saw kerf inlet and the bottom area of ​​the anode carbon block groove after being guided by the wing plate 405. This improves the airflow utilization rate and reduces ineffective dispersion. At the same time, it can also block the cutting particles from falling directly back to the vicinity of the strip air groove 402 to a certain extent, further improving the continuous working stability of the air guide mechanism.

[0038] When using a grooving machine for processing prebaked anode carbon blocks according to the present invention, the anode carbon block to be processed is first moved to the space between two clamps 21 inside the dust collection hood 2 by a feeding mechanism such as a conveyor belt or a robotic arm. At this time, the clamping cylinder set between the clamps 21 and the dust collection hood 2 is activated, driving the two clamps 21 to move towards each other, so that the clamping plate 211 at the bottom of the clamps 21 abuts against the two sides of the anode carbon block. Multiple anti-slip protrusions on the clamps 211 form friction-enhancing contact with the outer surface of the anode carbon block, thereby clamping and fixing the anode carbon block under the dust collection hood 2. After clamping, the dust collection hood 2 and the clamps 21 together form a stable clamping mechanism and form a relatively closed cutting and dust collection space above the anode carbon block. After the anode carbon block is clamped, the grooving mechanism is first adjusted according to the position and depth requirements of the groove to be processed. The lead screw motor 314 starts and drives the lifting lead screw 313 to rotate. The lifting lead screw 313, through the threaded engagement with the lead screw sleeve at the bottom of the movable seat 311, drives the movable seat 311 to move up and down along the tool support 3, thereby adjusting the cutting height of the circular saw 31 to determine the grooving depth. At the same time, the horizontal slide 315 fixed at the bottom of the tool support 3 slides along the horizontal slide rail 316 at the bottom of the main frame 1, thereby realizing the cutting depth of the saw. The support 3, together with the movable seat 311 and the circular saw 31, are adjusted laterally to determine the cutting position of the circular saw 31 relative to the anode carbon block. After the position of the circular saw 31 is adjusted, the two anti-chipping supports 4 move synchronously under the drive of the lifting motor 431. The lifting motor 431 drives one of the movable arms 43 to swing. The movable arm 43 drives the two anti-chipping supports 4 to move up and down relative to the horizontal slide 42 through the pin connection, so that the two anti-chipping supports 4 gradually move up to a position close to the bottom groove area of ​​the anode carbon block. As the anti-chipping support 4 moves upward and contacts the area adjacent to the bottom of the anode carbon block, the guide seat 44 slides along the top of the tool support 3 under the push of the reset cylinder 443 and the guidance of the guide slide 441 at the bottom, until the anti-chipping support 4 moves to the starting position of the circular saw 31 grooving. After clamping, tool setting and anti-chipping mechanism are completed, the circular saw 31 is driven to rotate at high speed. Then, the dust collection hood 2, together with the anode carbon block clamped and fixed below it, moves relative to the tool support 3 along the two tracks at the top of the main frame 1, so that the bottom of the anode carbon block moves relative to the circular saw 31. The circular saw 31 can then perform grooving on the bottom of the anode carbon block. During the grooving process, the air guide seat 401, located at the bottom of the anti-collision support 4 near the circular saw 31, simultaneously plays a role in air guiding and cleaning. Compressed air first enters the strip-shaped air groove 402 inside the air guide seat 401, and then is guided into the corresponding air nozzle 404 through multiple equally spaced inclined mounting seats 403. The multiple air nozzles 404 spray compressed air at an inclined direction onto the surface of the circular saw 31 and the groove area formed by the anode carbon block, so that the dust adhering to the surface of the circular saw 31 and the accumulated dust in the groove are blown away in time. At the same time, the wing plate 405 located at the bottom of the groove opening of the strip-shaped air groove 402 guides the airflow, so that the sprayed airflow flows more concentratedly towards the surface of the circular saw 31 and the bottom of the groove, thereby improving the blowing efficiency. Since a relatively sealed space is formed above the dust collection hood 2, and the equipment is equipped with top and bottom dust collection channels, the blown dust, dust and granular material can be collected in time, avoiding the accumulation of a large amount of dust on the surface of the circular saw 31 and in the groove, ensuring the continuity and stability of the cutting process. Once the anode carbon block has moved to the predetermined grooving length, the relative feed stops, and the circular saw 31 completes the grooving of the bottom of the anode carbon block. Subsequently, the lifting motor 431 reverses its movement, causing the movable arm 43 to swing in the opposite direction, causing the two anti-collision edge supports 4, together with the end face supports 41, to move down and disengage from the groove area of ​​the anode carbon block. The reset cylinder 443, with the assistance of the buffer spring 446, drives the relevant components to return to their initial position. Afterward, the lead screw motor 314 can drive the movable seat 311 and the circular saw 31 to descend or retract to the initial standby position as needed, and the clamping cylinder... The action causes the clamp 21 to open, thereby releasing the clamp on the anode carbon block. At this time, the anode carbon block reaches above the roller conveyor chain 11, and the lower surface of the anode carbon block contacts the upper surface of the roller conveyor chain 11. The processed anode carbon block continues to be transported to the next station by the roller conveyor chain 11 or subsequent conveying device to complete a complete grooving cycle. For anode carbon blocks of different specifications, it is only necessary to adjust the clamping range of the clamp 21, the vertical position of the circular saw 31, and the horizontal position of the tool support 3 accordingly to achieve processing of different groove depths and different groove positions.

[0039] It should be noted that, in the actual application of anode carbon blocks, straight grooves, inclined grooves and circular arc grooves are involved. For different grooving operations, the circular saw 31 and the anti-breakage support 4 perform different movements. When machining straight grooves, the tool support 3 and the circular saw 31 are kept at a fixed height, the anti-chipping support 4 is kept at a fixed height, and the dust collection hood 2 drives the anode carbon block to move along the track until the predetermined groove length is reached, thus completing the machining of straight grooves. When machining the inclined groove, the circular saw 31 maintains an upward or downward posture as the dust collection hood 2 moves the anode carbon block along the track, and the anti-chipping support 4 and the tool support 3 maintain a fixed height throughout the process. When machining the arc groove, the height of the circular saw 31 is kept fixed at first. When the dust collection hood 2 and the anode carbon block move to the arc area of ​​the groove, the circular saw 31 moves downward. The anti-chipping support 4 and the tool support 3 keep their heights fixed throughout the process. In summary, when the circular saw 31 is machining a straight groove, it is in a constant depth cutting state. The anti-chipping support 4 mainly provides synchronous fitting support for both sides and the end of the straight groove. When machining an inclined groove, the circular saw 31 and the anode carbon block form an inclined cutting relationship. The anti-chipping support 4 maintains fitting support for both sides of the inclined groove opening. When machining an arc groove, the circular saw 31 forms an arc-shaped groove bottom or groove tail transition area within a predetermined non-through stroke. The anti-chipping support 4 and the end face support 41 provide key anti-chipping protection for both sides of the arc groove opening and the terminal area.
