Description

Technical Field

[0001] The invention belongs to the technical field of anode carbon block slotting equipment, and in particular relates to a continuous electrolytic aluminum anode carbon block slotting machine. Background Art

[0002] The uneven density of electrolytic aluminum anode carbon blocks is due to the multi-link coupling effect of the manufacturing process. For example, raw material mixing defects: petroleum coke particles and liquid asphalt are prone to form "coke balls" and "asphalt-rich areas" during the kneading process, resulting in excessive local binder and the formation of densified nodes; molding pressure fluctuations: the pressure field is unevenly distributed during the vibration molding stage, resulting in the core density of the carbon block being significantly higher than the surface layer; baking shrinkage differences: during the baking of carbon blocks, the difference in the escape rate of volatiles causes anisotropic shrinkage, forming an internal residual stress concentration zone; graphitization gradient: in the high-temperature zone (>1100℃), the carbon structure does not completely transform into a graphite state, resulting in a hard microcrystalline area, etc.

[0003] Slotting anode carbon blocks is a critical step in the electrolytic aluminum production process. Traditional anode carbon block slotting machines perform continuous slotting by pushing multiple carbon blocks sequentially through a cutting machine. However, in practice, due to the uneven density of the anode carbon block material, certain areas are denser, resulting in significantly increased cutting resistance.

[0004] When a saw blade encounters a high-density area, cutting resistance increases significantly. If the carbon block's speed remains constant, the saw blade will be subjected to excessive compressive pressure. Prolonged operation in this state will lead to increased saw blade wear. As the saw blade wears, its cutting edge gradually dulls, significantly reducing cutting efficiency. In severe cases, the saw blade risks breaking due to excessive load, resulting in serious damage to the main slotting machine and production interruption. Based on this, we propose a continuous electrolytic aluminum anode carbon block slotting machine. Summary of the Invention

[0005] The purpose of the present invention is to provide a continuous electrolytic aluminum anode carbon block slotting machine, which aims to solve the technical problem of a sudden increase in cutting resistance when the saw blade passes through a high-density area during the slotting process of the electrolytic aluminum anode carbon block.

[0006] The loading frame is provided with a clamping mechanism for clamping and fixing the electrolytic aluminum anode carbon blocks, and the workbench is provided with a movable frame slidably connected to the movable frame, and the movable frame is slidably connected to the charging frame, and the movable frame is used to drive the electrolytic aluminum anode carbon blocks to move and slot through the charging frame. The top of the movable frame is provided with fixed plates on both sides of the charging frame, and the fixed plates on both sides are symmetrically arranged with limit members, and multiple groups of limit members are arranged at intervals on one side of the fixed plate, and the limit member slides vertically and passes through the fixed plate, and one end of the limit member is provided with a V-shaped surface, and the other end is provided with a baffle, and a first spring is provided between the baffle and the fixed plate, and the V-shaped surfaces of the limit members on both sides are arranged opposite to each other, and the V-shaped surfaces contact the charging frame to limit the charging frame.

[0007] When the saw blade is rotated to cut grooves to the high-density area of the electrolytic aluminum anode carbon block, the limit parts abutting against the loading frame provide it with a certain limit force. When the cutting resistance is greater than the limit force, the loading frame squeezes this group of limit parts to its two sides and moves to the next group of limit parts. The cutting resistance is reduced, avoiding a sudden and substantial increase in cutting resistance, thereby reducing the risk of the saw blade being damaged due to excessive cutting resistance.

[0008] Furthermore, the elastic coefficient of the first spring gradually increases in the direction away from the movable frame, slide rails are provided on both sides of the grooving main unit, the movable frame is slidably connected to the slide rails, and an n-shaped baffle is provided at one end of the slide rail, and the n-shaped baffle is used to limit the loading frame.

[0009] The limiter provides a stepped limiting force for the loading frame, which reduces the risk of damage to the saw blade. At the same time, the gradually increasing limiting force helps to rotate the saw blade to cut the high-density area of the electrolytic aluminum anode carbon block.

[0010] Furthermore, a buffer tank is provided on the top of the movable frame, and the buffer tank is filled with liquid medium. The buffer tank is penetrated by a fixed rod which is sealingly and slidingly connected to the buffer tank. One end of the fixed rod is connected to the loading frame. The sliding direction of the fixed rod is consistent with the loading frame. The fixed rod located in the buffer tank is sleeved with a first buffer plate. The edge of the first buffer plate is sealingly and slidingly connected to the inner wall of the buffer tank. The first buffer plate is provided with a first through hole.

[0011] When the loading frame moves, the fixed rod drives the first buffer plate to move in the buffer tank, and the liquid medium flows from one side of the first buffer plate to the other side through the first through hole. The resistance generated by the flow is transmitted to the electrolytic aluminum anode carbon block, buffering the movement of the loading frame and helping to ensure a smooth transition of the cutting resistance.

[0012] The lifting mechanism is a bottom end of the gear train, and the gear train is connected with the gear train by the spring, and the gear train is connected with the gear train by the spring.

[0013] The one-way limit rack and the limit block cooperate with the limit fixing rod to help reduce the violent fluctuations generated during the cutting process of the electrolytic aluminum anode carbon block by the rotating saw blade, so that the rotating saw blade maintains a relatively stable cutting force on the electrolytic aluminum anode carbon block.

[0014] Furthermore, the fixed rod in the buffer tank is provided with a limiting flange and a second buffer plate, the second buffer plate is located between the first buffer plate and the limiting flange, the second buffer plate is sealingly and slidingly connected to the fixed rod, and the edge of the second buffer plate is sealingly and slidingly matched with the inner wall of the buffer tank, the second buffer plate is provided with a second through hole, the number of the second through holes is the same as that of the first through holes and they are aligned, and the aperture of the second through hole is smaller than that of the first through hole.

[0015] When the first buffer plate drives the second buffer plate to move, the liquid medium flows through the second through hole and the first through hole. Compared with the liquid medium only flowing through the first through hole, the flow area is reduced and the flow resistance is increased, that is, the cutting resistance of the rotating saw blade is slowly increased.

[0016] Furthermore, a limiting slip ring is provided on the sliding sleeve of the fixed rod located in the buffer tank, a second spring is provided between the limiting slip ring and the second buffer plate, the limiting slip ring is spaced from the inner wall of the buffer tank, a slide groove is provided on the inner wall of the buffer tank, the slide groove is located in the buffer tank close to the loading frame, the limiting plate is slidably connected in the slide groove, the limiting plate slides radially along the buffer tank, a third spring is provided between the limiting plate and the bottom surface of the slide groove, the adjacent edges of the limiting plates on both sides are symmetrically provided with inclined limiting surfaces, the inclined limiting surfaces on the limiting plates form a wave-like structure, and the limiting plates on both sides cooperate with the limiting slip rings.

[0017] The limit plate forms multiple "peaks" and "troughs". In the process of the limit slip ring squeezing and passing through the "peaks" of the limit plate into the "trough", the cutting resistance borne by the saw blade gradually increases and then decreases. The second spring restores the elastic potential energy, and the limit slip ring squeezes the next peak again. The cutting resistance borne by the saw blade gradually increases again. This is repeated, which helps to cut the electrolytic aluminum anode carbon block while protecting the saw blade.

[0018] Furthermore, the limiting force generated by all the third springs in the sliding grooves on both sides acting on the limiting plate is equal to the elastic force generated by half the deformation of the second spring.

[0019] The present invention has the following beneficial effects.

[0020] 1. The present invention provides a sliding fit between the movable frame and the loading frame, and multiple groups of limit members are evenly spaced on the fixed plates on both sides of the loading frame. The first spring on the limit member cooperates with the V-shaped surface to limit the loading frame, thereby providing a certain limiting force for the loading frame. When the cutting resistance of the saw blade is greater than the limiting force of a group of limit members, the loading frame squeezes the group of limit members to its two sides and moves toward the next group of limit members. The elastic coefficient of the first spring gradually increases in the direction away from the loading frame, thereby causing the cutting resistance to increase in a step-by-step manner, which can effectively reduce the risk of damage to the saw blade due to a sudden and substantial increase in cutting resistance.

[0021] 2. In the present invention, a buffer tank is provided on the movable frame, and the fixed rod is used to drive the first buffer plate to move. The liquid medium flows through the first through hole to generate resistance to buffer the drastic change of the cutting force; the first buffer plate drives the second buffer plate to move, and the liquid medium flows through the second through hole and the first through hole. Since the flow area of the liquid medium is reduced, the resistance gradually increases, and the corresponding cutting resistance borne by the saw blade gradually increases; the fixed rod continuously squeezes the second spring through the first buffer plate and the second buffer plate, and the corresponding limit slip ring continuously squeezes the limit plate. The limit slip ring passes through the first group of "peaks" on the limit plate and enters the first group of troughs. The elastic potential energy of the second spring is restored, and the cutting force gradually increases and then decreases. This is repeated. While protecting the saw blade, it helps the saw blade to cut the high-density area of the electrolytic aluminum anode carbon block. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0030] Example 1

[0031] Reference Figure 1 This embodiment discloses a continuous electrolytic aluminum anode carbon block slotting machine, which is used to continuously slot 400 electrolytic aluminum anode carbon blocks.

[0032] According to an embodiment of the present application, a continuous electrolytic aluminum anode carbon block slotting machine includes a workbench, a movable frame 200 and a charging frame 300 arranged on the workbench.

[0033] The specific structure and connection relationship of each component are as follows:

[0034] 1. Workbench

[0035] Reference Figure 1The workbench is provided with a slotting machine 100 and a conveying unit. The slotting machine 100 has two saw blades 101. Along the conveying direction of the electrolytic aluminum anode carbon block, the slotting machine 100 is provided with a conveying unit on both sides. The other two sides of the slotting machine 100 are parallel to each other and a slide rail 201 is provided on the slide rail 201 at one end of the electrolytic aluminum anode carbon block to be slotted (refer to Figure 2 ).

[0036] The above arrangement can realize that the anode carbon block to be grooved is transported to one side of the groove cutting main machine 100 via the conveying unit, and the groove cutting main machine 100 uses the saw blade 101 to groove the electrolytic aluminum anode carbon block 400. The grooved electrolytic aluminum anode carbon block is transported to the subsequent process via the conveying unit.

[0037] 2. Mobile rack 200 and loading frame 300

[0038] Reference Figure 1 , the movable frame 200 is slidably connected to the slide rails 201 on both sides, (refer to Figure 2 ) The loading frame 300 is slidably arranged on the movable frame 200, and a clamping mechanism is provided in the loading frame 300. The upper portion of the loading frame 300 extends outward from the top of the movable frame 200. (Refer to Figure 3 ) A fixed plate 210 is provided on the top of the movable frame 200, and the fixed plate 210 is arranged on both sides of the loading frame 300, and the fixed plate 210 extends to the outside of the movable frame 200 along the moving direction of the movable frame 200, and the limiting parts 211 are symmetrically provided on the fixed plates 210 on both sides.

[0039] Reference Figure 3 Taking the fixed plate 210 on one side as an example, a plurality of limiting members 211 are evenly spaced along the length direction of the fixed plate 210, and the limiting members 211 are arranged in the horizontal direction. The limiting members 211 are vertically and slidably penetrate the fixed plate 210, and a V-shaped surface 212 is provided at one end of the limiting member 211 and a baffle is provided at the other end. A first spring 213 is provided between the baffle and the fixed plate 210, and the V-shaped surfaces 212 of the limiting members 211 on the fixed plates 210 on both sides are arranged opposite to each other.

[0040] Preferably, three groups of limiters 211 are spaced apart on the fixed plate 210 , wherein the first group of limiters 211 , the second group of limiters 211 and the third group of limiters 211 are spaced apart in sequence in the direction away from the movable frame 200 , and the elastic coefficient of the first spring 213 on the limiter 211 gradually increases.

[0041] The mobile frame 200 has a drive system that drives it back and forth along the slide rails 201. Detection units 301 are located on either side of the loading frame 300. These units control the speed of the mobile frame 200 by detecting the distance between the anode carbon blocks 400 to be electrolyzed and the slotting machine 100. These detection units 301 are image recognition sensors.

[0042] The electrolytic aluminum anode carbon block slotting machine of the present invention has a control panel, which is electrically connected to all electrical components in the slotting machine. The control panel, conveying unit, slotting main unit 100, clamping mechanism and driving system are all existing mechanisms.

[0043] The above setting can be realized, the movable frame 200 can drive the loading frame 300 to move back and forth along the slide rail 201, the loading frame 300 stably clamps the electrolytic aluminum anode carbon block 400 through the clamping mechanism, the loading frame 300 slides with the movable frame 200, the loading frame 300 contacts the V-shaped surface 212 of the limiting member 211, and a group of limiting members 211 are used to limit the loading frame 300. The limiting members 211 located on one side of the loading frame 300 from near to far can provide it with a gradually increasing limiting force.

[0044] The working process of the continuous electrolytic aluminum anode carbon block slotting machine in this embodiment is as follows:

[0045] First, the control panel controls the conveying unit to convey the electrolytic aluminum anode carbon block 400 to be slotted into the loading frame 300, and the conveying unit stops working. The clamping mechanism of the loading frame 300 stably clamps the electrolytic aluminum anode carbon block 400. At the same time, the grooving main unit 100 drives the saw blade 101 to rotate, and the movable frame 200 and the loading frame 300 are both in the initial position. The loading frame 300 contacts the n-shaped baffle 202, and the loading frame 300 contacts the adjacent first group of limit members 211.

[0046] Then, the movable frame 200 drives the loading frame 300 to move along one end of the slide rail 201 to the other end. At this time, the first set of limit members 211 limits the loading frame 300. During the movement, the loading frame 300 and the movable frame 200 remain relatively stationary. When the detection unit 301 on one side detects that the electrolytic aluminum anode carbon block 400 moves close to the saw blade 101, the drive system of the movable frame 200 controls the movable frame 200 to drive the loading frame 300 to move slowly. The two rotating saw blades 101 cut grooves on the electrolytic aluminum anode carbon block 400, which helps to ensure the regularity of the grooves on the electrolytic aluminum anode carbon block 400. When the detection unit 301 on the other side detects that the rotating saw blade 101 is close to the end of the electrolytic aluminum anode carbon block 400, the drive system of the movable frame 200 controls the movable frame 200 to drive the loading frame 300 to keep cutting grooves slowly, thereby ensuring the quality of the cutting grooves.

[0047] Subsequently, the movable rack 200 drives the electrolytic aluminum anode carbon block 400 after groove cutting to the end of the slide rail 201 through the loading frame 300, and the electrolytic aluminum anode carbon block 400 moves to the conveying unit. The clamping mechanism separates from the electrolytic aluminum anode carbon block 400, and the conveying unit conveys the electrolytic aluminum anode carbon block 400 after groove cutting to the next process.

[0048] Finally, the driving system of the movable rack 200 controls the movable rack 200 to move in the reverse direction, and the loading frame 300 moves to abut against the n-shaped baffle 202 , forcing the loading frame 300 and the movable rack 200 to return to their initial positions.

[0049] During the grooving process of the electrolytic aluminum anode carbon block 400 by the grooving main machine 100, under normal conditions, the sum of the cutting resistances between the two rotating saw blades 101 and the electrolytic aluminum anode carbon block 400 is less than the sum of the limiting forces generated by the first springs 213 on a set of limiting members 211 abutting against the loading frame 300. The cutting resistance of the saw blade 101 to the electrolytic aluminum anode carbon block 400 remains relatively stable, and the movable frame 200 and the loading frame 300 remain relatively stationary, so that the electrolytic aluminum anode carbon block 400 can be grooved.

[0050] During the grooving process of the grooving main machine 100 on the electrolytic aluminum anode carbon block 400, when the rotating saw blade 101 passes through the high-density area in the electrolytic aluminum anode carbon block 400, the cutting resistance between the electrolytic aluminum anode carbon block 400 and the rotating saw blade 101 increases significantly. When the sum of the cutting resistances is greater than the sum of the limiting forces of the two limiting members 211 on the loading frame 300, the movable frame 200 continues to move forward (i.e., moves toward the conveying end of the electrolytic aluminum anode carbon block 400), and the electrolytic aluminum anode carbon block 400 first remains relatively stationary (at this time, the rotating saw blade 101 slowly cuts the electrolytic aluminum anode carbon block 400), and the electrolytic aluminum anode carbon block 400 forces the loading frame 300 to move backward relative to the movable frame 200 through the clamping mechanism (i.e., moves toward the conveying front end of the electrolytic aluminum anode carbon block 400). At this time, the loading frame 300 continues to squeeze the V-shaped surface 212 of the first group of limiting members 211 abutting against it, so that the first group of limiting members 211 moves away from the loading frame 300 and compresses the first spring 213 on the first group of limiting members 211.

[0051] The loading frame 300 moves to the adjacent second set of stoppers 211 and abuts against the V-shaped surface 212 of the second set of stoppers 211. Because the elastic coefficient of the first spring 213 on the stoppers 211 farther from the movable frame 200 is greater, the limiting force provided by the second set of stoppers 211 abutting the loading frame 300 is greater than the limiting force provided by the first set of stoppers 211, ensuring a greater cutting force between the electrolytic aluminum anode carbon block 400 and the rotating saw blade 101. If the rotating saw blade 101 still has not passed through the high-density area of the electrolytic aluminum anode carbon block 400, the loading frame 300 presses against the second set of stoppers 211 to compress the first spring 213 thereon, and then the loading frame 300 moves to abut against the third set of stoppers 211.

[0052] After the movable rack 200 drives the electrolytic aluminum anode carbon block 400 to complete the slotting through the loading frame 300, the movable rack 200 drives the loading frame 300 to move in the opposite direction to the initial position, and the loading frame 300 contacts the n-shaped baffle 202. Under the blocking and limiting action of the n-shaped baffle 202, the movable rack 200 continues to reset and move, so that the loading frame 300 returns to the initial position on the movable rack 200, that is, the loading frame 300 moves to the side of the first group of limiting members 211 closest to the movable rack 200.

[0053] By increasing the limiting force of the electrolytic aluminum anode carbon block 400 in a multi-stage step-by-step manner, the cutting force of the electrolytic aluminum anode carbon block 400 can be increased in a multi-stage step-by-step manner. The relative movement between the movable frame 200 and the loading frame 300 can avoid the rotating saw blade 101 from being subjected to a sudden and substantial increase in cutting resistance, reduce the occurrence of breakage and damage of the rotating saw blade 101, and help ensure the continuous operation of the electrolytic aluminum anode carbon block grooving machine.

[0054] Example 2

[0055] This embodiment discloses a continuous electrolytic aluminum anode carbon block slotting machine. Based on the first embodiment, the loading frame 300 has the function of buffering the cutting resistance between the saw blade 101 and the electrolytic aluminum anode carbon block 400 when moving between adjacent limit members 211.

[0056] According to a continuous electrolytic aluminum anode carbon block slotting machine according to an embodiment of the present application, on the basis of Example 1, the movable frame 200 is provided with a buffer tank 220, and the loading frame 300 is provided with a fixed rod 310 sealed and slidably connected to the buffer tank 220.

[0057] The buffer tank 220 is filled with liquid medium, the sliding direction of the fixed rod 310 is the same as the moving direction of the loading frame 300, the fixed rod 310 is located in the buffer tank 220, and the rod body is sleeved with a first buffer plate 311. The first buffer plate 311 is perpendicular to the fixed rod 310, and a plurality of first through holes 3111 are evenly distributed on the first buffer plate 311. The edge of the first buffer plate 311 is sealed and slidably fitted with the inner wall of the buffer tank 220.

[0058] The above setting can be achieved. The fixed rod 310 moves with the loading frame 300, and the fixed rod 310 drives the first buffer plate 311 to slide in the buffer tank 220. The liquid medium in the buffer tank 220 flows from one side of the first buffer plate 311 to the other side through the first through hole 3111, generating flow resistance.

[0059] The working process of this embodiment is similar to that of the first embodiment and is described in detail as follows:

[0060] The loading frame 300 squeezes the first set of limit members 211 abutting against it, forcing the first spring 213 on the first set of limit members 211 to compress, and the loading frame 300 moves toward the second set of limit members 211. The loading frame 300 drives the fixed rod 310 to move, and the fixed rod 310 drives the first buffer plate 311 located in the buffer tank 220 to move. The resistance generated by the flow of the liquid medium in the buffer tank 220 through the first through hole 3111 of the first buffer plate 311 is transmitted to the electrolytic aluminum anode carbon block 400, so that the cutting resistance between the rotating saw blade 101 and the electrolytic aluminum anode carbon block 400 is the movement resistance suffered by the first buffer plate 311, which helps to buffer the drastic changes in the cutting resistance.

[0061] Example 3

[0062] The present embodiment discloses a continuous electrolytic aluminum anode carbon block slotting machine, which is further improved on the basis of the second embodiment to reduce the violent fluctuations generated when the rotating saw blade 101 cuts the electrolytic aluminum anode carbon block 400.

[0063] Reference Figure 3 The buffer tank 220 is provided with a fixed frame 230, and the fixed frame 230 is slidably connected to a sliding frame 231 (refer to Figure 5 ) The sliding frame 231 includes a connecting frame 2313 located above the fixed frame 230, a one-way limiting rack 2311 located below the fixed frame 230, and a connecting rod 2312 that slides vertically through the fixed frame 230. The upper and lower ends of the connecting rod 2312 are respectively connected to the connecting frame 2313 and the one-way limiting rack 2311. The connecting rod 2312 between the fixed frame 230 and the connecting frame 2313 is sleeved with a tension spring 233. The upper and lower ends of the tension spring 233 are respectively connected to the connecting frame 2313 and the fixed frame 230.

[0064] Accordingly, (cf. Figure 5 ) A limiting block 312 is provided at the upper part of one end of the fixing rod 310 away from the loading frame 300, which cooperates with the one-way limiting rack 2311.

[0065] Reference Figure 2 The connecting frame 2313 is provided with a support rod 232. The support rod 232 is in a Z-shaped structure. One end of the support rod 232 is located on one side of the charging frame 300 and is connected to the connecting frame 2313. The other end extends to the other side of the charging frame 300 and has an inclined surface at its end. The inclined surface is aligned with the upper edge of the n-shaped baffle 202. (Refer to Figure 4 ) A channel 302 is provided on the upper part of the loading frame 300 for the support rod 232 to pass through, and a distance is left between the upper and lower surfaces of the support rod 232 and the upper and lower inner walls of the channel 302.

[0066] The above setting can achieve that when the limit block 312 contacts the one-way limit rack 2311, the fixed rod 310 can only move in one direction; when the support rod 232 abuts and slides against the N-shaped baffle 202, the support rod 232 drives the connecting frame 2313, the connecting rod 2312 and the one-way limit rack 2311 to rise, the limit block 312 separates from the one-way limit rack 2311, and the tension spring 233 is in a stretched state.

[0067] The working process of this embodiment is similar to that of embodiment 2 and is described in detail as follows:

[0068] When the rotating saw blade 101 cuts the high-density area on the electrolytic aluminum anode carbon block 400, the loading frame 300 drives the fixed rod 310 to move, and the limit block 312 on the fixed rod 310 always remains in contact with the one-way limit rack 2311 to prevent the fixed rod 310 from moving in the opposite direction, so as to reduce the violent fluctuations generated during the cutting process of the electrolytic aluminum anode carbon block 400 by the rotating saw blade 101, thereby allowing the rotating saw blade 101 to maintain a relatively stable cutting force on the electrolytic aluminum anode carbon block 400.

[0069] After the slotting of the electrolytic aluminum anode carbon block 400 is completed, the movable frame 200 drives the loading frame 300 to move in the opposite direction along the slide rail 201 to the initial position.

[0070] First, the inclined surface of the end of the support rod 232 contacts the upper edge of the n-shaped baffle 202;

[0071] Then, the upper edge of the n-shaped baffle 202 slides along the inclined surface until it contacts the bottom surface of the support rod 232, that is, the support rod 232 is lifted to the upper surface of the n-shaped baffle 202. Accordingly, the support rod 232 drives the connecting frame 2313, the connecting rod 2312 and the one-way limit rack 2311 to rise synchronously. At this time, the tension spring 233 is in a stretched state, and the one-way limit rack 2311 is separated from the limit block 312.

[0072] Next, the loading frame 300 moves to contact the n-shaped baffle 202 . As the movable rack 200 continues to move, the first buffer plate 311 moves to one end of the buffer tank 220 , and the loading frame 300 and the movable rack 200 return to their initial positions.

[0074] This embodiment discloses a continuous electrolytic aluminum anode carbon block slotting machine, which is further improved on the basis of Example 3.

[0075] Reference Figure 6 The fixing rod 310 is provided with a limiting flange 316 , a second buffer plate 313 and a limiting slip ring 314 .

[0076] The fixing rod 310 is provided with a limiting flange 316 . A certain distance is spaced between the limiting flange 316 and the first buffer plate 311 . The limiting flange 316 is located in the buffer tank 220 .

[0077] Reference Figure 5 The fixing rod 310 is sleeved with a second buffer plate 313 which is in sealing and sliding connection with the fixing rod 310. The second buffer plate 313 is located in the buffer tank 220. (Refer to Figure 6 ) and the second buffer plate 313 is located between the limiting flange 316 and the first buffer plate 311, the edge of the second buffer plate 313 is sealed and slidably matched with the inner wall of the buffer tank 220, and the second buffer plate 313 is provided with second through holes 3131. The number of the second through holes 3131 and the layout positions of the first through holes 3111 are the same, and the aperture of the second through holes 3131 is smaller than that of the first through holes 3111.

[0078] Reference Figure 6 The fixed rod 310 is fitted with a limiting slip ring 314 that is slidably connected thereto. The limiting slip ring 314 is located within the buffer tank 220, with a gap between the limiting slip ring 314 and the inner wall of the buffer tank 220. The limiting slip ring 314 is located on the side of the second buffer plate 313 away from the first buffer plate 311. A second spring 315 is provided between the limiting slip ring 314 and the second buffer plate 313. The second spring 315 is slidably fitted around the fixed rod 310, with its ends connected to the second buffer plate 313 and the limiting slip ring 314, respectively. The area of the gap between the limiting slip ring 314 and the buffer tank 220 is much larger than the sum of the areas of all the second through holes 3131 in the second buffer plate 313.

[0079] Reference Figure 6 Two groups of slide grooves 221 are arranged on the inner wall of the buffer tank 220. The slide groove 221 is located at one end of the buffer tank 220 close to the loading frame 300. A limiting plate 223 is slidably connected in the slide groove 221. A third spring 222 is provided between the limiting plate 223 and the bottom surface of the slide groove 221. Preferably, four groups of third springs 222 are arranged in the slide groove 221 on each side. Under the action of the third spring 222, the limiting plates 223 on both sides are close to each other.

[0080] The limiting force on the limiting slip ring 314 generated by all the third springs 222 connected to the limiting plates 223 on both sides is equal to the elastic force generated by half the deformation of the second spring 315 on the limiting slip ring 314 .

[0081] Reference Figure 6 The adjacent edges of the limiting plates 223 on both sides are symmetrically provided with inclined limiting surfaces, and one side of the limiting plate 223 is provided with multiple inclined limiting surfaces, which are connected to form a wave-like structure, that is, forming continuously alternating "peaks" and "troughs".

[0082] The above setting can be realized, the fixed rod 310 drives the first buffer plate 311 to move to fit with the second buffer plate 313, and drives the second buffer plate 313 to move, the liquid medium flows through the second through hole 3131 and the first through hole 3111, the flow resistance of the liquid medium increases, and the corresponding movement resistance of the fixed rod 310 becomes larger, and the cutting force of the rotating saw blade 101 on the electrolytic aluminum anode carbon block 400 increases.

[0083] The first buffer plate 311 drives the second buffer plate 313 to continuously compress the second spring 315. Accordingly, the second spring 315 compresses the limiting plate 223 via the limiting slip ring 314. When the second spring 315 deforms by more than half, the limiting slip ring 314 compresses the limiting plate 223 until the limiting slip ring 314 passes through the first set of "peaks" and enters the first set of "troughs," allowing the second spring 315 to recover its elastic potential energy.

[0084] The working process of this embodiment is the same as that of embodiment 3, and is described in detail as follows:

[0085] First, when the rotating saw blade 101 cuts the high-density area on the electrolytic aluminum anode carbon block 400, the loading frame 300 drives the fixed rod 310 to move. The loading frame 300 presses the first set of limit members 211 abutting against it to both sides of the loading frame 300, and the loading frame 300 moves to the second set of limit members 211. Correspondingly, the fixed rod 310 drives the first buffer plate 311 to move toward the second buffer plate 313. During the movement of the first buffer plate 311 toward the second buffer plate 313, the liquid medium mainly flows from one side of the first buffer plate 311 through the first through hole 3111 to the other side of the first buffer plate 311. The resistance generated by the liquid medium passing through the first buffer plate 311 is used to regulate the cutting resistance between the rotating saw blade 101 and the electrolytic aluminum anode carbon block 400.

[0086] Secondly, if the rotating saw blade 101 has not passed through the high-density area on the electrolytic aluminum anode carbon block 400, the loading frame 300 squeezes the second set of limiters 211 to both sides thereof. At this time, the first buffer plate 311 drives the second buffer plate 313 to continue to move. The liquid medium mainly flows from one side of the second buffer plate 313 through the first through hole 3131 and the second through hole 3111. Since the aperture of the second through hole 3131 is smaller than that of the first through hole 3111, the flow area of the liquid medium is reduced, and the corresponding resistance is increased. The second buffer plate 313 continues to compress the second spring 315, and the resistance experienced by the fixing rod 310 gradually increases. Accordingly, the cutting force of the rotating saw blade 101 on the electrolytic aluminum anode carbon block 400 gradually increases.

[0087] Then, the loading frame 300 continues to move toward the third set of limit members 211, and the limit slip ring 314 continues to squeeze the limit plate 223. When the second spring 315 is deformed by more than half, the limit slip ring 314 squeezes the limit plate 223 to slide into the slide groove 221. The limit slip ring 314 passes through a group of "peaks" of the limit plates 223 on both sides and enters a group of "troughs". At this time, the elastic potential energy of the second spring 315 is restored, and the cutting force of the rotating saw blade 101 on the electrolytic aluminum anode carbon block 400 is reduced. As the loading frame 300 drives the fixed rod 310 to continue to move, the first buffer plate 311 drives the second buffer plate 313 to squeeze the second spring 315 again. Accordingly, the limit slip ring 314 squeezes the limit plate 223 again.

[0088] Subsequently, this process is repeated, and the cutting force between the rotating saw blade 101 and the electrolytic aluminum anode carbon block 400 is regulated by gradually increasing pressure, so that the rotating saw blade 101 passes through the high-density area on the electrolytic aluminum anode carbon block 400, and completes continuous and stable grooving of the electrolytic aluminum anode carbon block 400 while protecting the rotating saw blade 101.

[0089] Finally, when the moving frame 200 drives the loading frame 300 to move and reset, the buffer tank 220 gradually approaches the loading frame 300, and the corresponding first buffer plate 311 moves toward one end of the buffer tank 220. The limiting flange 316 drives the second buffer plate 313 to move, and the second buffer plate 313 drives the limiting slip ring 314 to move and reset to the side of the limiting plate 223 through the second spring 315.

[0090] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
