Description

Technical Field

[0001] This application relates to the field of sawing equipment technology, and in particular to a batch sawing equipment for processing round steel couplings. Background Technology

[0002] Couplings are devices used in mechanical engineering to connect two shafts or a shaft and a rotating component to transmit motion and torque. Round steel is a solid circular steel material used to manufacture the main structure of a coupling. When manufacturing the main body of a coupling using round steel, a sawing device is needed to cut the round steel into appropriate sizes to facilitate subsequent processing of the round steel.

[0003] Some existing round steel sawing equipment typically uses a fixed plate and a movable plate to clamp and fix the longitudinally arranged round steel bars. Then, the circular cutter passes through the interval space in the fixed plate and cuts the round steel bars sequentially from top to bottom. Through the above actions, batch sawing of round steel bars can be achieved.

[0004] However, in actual work, since the round steel is only subjected to the relative clamping forces on the left and right sides, it is easy for the round steel to move slightly upward during the sawing process, which affects the sawing accuracy of the round steel. At the same time, the longitudinally arranged round steels are in contact with each other, and the vibration generated by the sawing round steel will be directly transmitted to the adjacent round steel, causing the round steel to move slightly, which further affects the sawing accuracy of the round steel. Summary of the Invention

[0005] This application proposes a batch sawing equipment for processing round steel for couplings, which has the advantage of reducing the probability of slight displacement of the round steel, thereby solving the problem that slight movement of the round steel affects the sawing accuracy.

[0006] To achieve the above objectives, this application adopts the following technical solution: a batch sawing equipment for processing round steel for couplings, comprising: a worktable, a fixing mechanism provided on the upper side of the worktable, the fixing mechanism including a fixed plate and a movable plate, the fixed plate being fixedly installed on the right side of the upper side of the worktable, the movable plate being slidably installed on the left side of the upper side of the worktable, a sawing mechanism being provided on the side of the fixed plate facing away from the movable plate, clamping plates being fixedly installed on the opposite sides of the fixed plate and the movable plate, the clamping plates being grouped in pairs, two groups of clamping plates on the same horizontal line clamping the round steel together, the clamping plates being inclined, each group of clamping plates being symmetrical about the corresponding round steel, two groups of clamping plates on the same horizontal line being symmetrical about the corresponding round steel, and each group of clamping plates adjacent in the longitudinal direction having a gap; A peeling mechanism is provided on the upper side of the round steel bar to remove the oxide scale from the upper area of ​​the round steel bar sawing zone.

[0007] Furthermore, the peeling mechanism includes: The friction element is located at different positions on the round steel corresponding to the clamping plate. The inner diameter of the friction element is the same as the diameter of the round steel. A screw is provided inside the movable plate at the position corresponding to the friction element. The screw and the connecting block of the friction element form a transmission connection.

[0008] Furthermore, the peeling mechanism also includes: Accumulation grooves are formed on both sides of the inner surface of the friction component along the axial direction. The depth of the accumulation grooves is measured in millimeters and gradually increases from the opening inwards.

[0009] Furthermore, the peeling mechanism also includes: A baffle is fixedly installed on the inner wall of the accumulation tank opening. The baffle is made of flexible material and its cross-sectional area is smaller than that of the accumulation tank opening.

[0010] Furthermore, the friction element is a grinding block of silicon carbide abrasive and nylon matrix, the baffle is made of wear-resistant rubber material, and the inner surface of the accumulation groove is made with a slightly rough texture.

[0011] Furthermore, a preheating mechanism is provided on the outer side of the round steel bar, the preheating mechanism comprising: A preheating source is set on the upper side of the round steel bar. The preheating source and the clamping plate correspond to different positions of the round steel bar. The preheating source and the friction component are arranged symmetrically. An induction heating coil is sleeved on the outside of a round steel bar. The inner diameter of the induction heating coil is larger than the diameter of the round steel bar. The induction heating coil is electrically fixedly connected to a preheating source. A screw is provided inside the movable plate at the position corresponding to the preheating source. The screw is connected to the connecting block of the preheating source in a transmission manner.

[0012] Furthermore, the fixing mechanism also includes: The fixed platform is fixedly installed on the upper side of the workbench and located where the movable plate faces away from the fixed plate. A clamping cylinder is fixedly installed inside the fixed platform. The telescopic rod of the clamping cylinder is fixedly connected to the movable plate. The clamping plate is made of wear-resistant bakelite.

[0013] Furthermore, the sawing mechanism includes: The sawing table is fixedly connected to the workbench; A cutting blade is positioned on the side of the sawing table facing the fixed plate, and the sawing table drives the cutting blade to move up and down; The inside of the workbench and the inside of the fixed plate are longitudinally connected by a through groove corresponding to the position of the cutter, for the cutter to pass through.

[0014] This application has the following beneficial effects: This application provides a batch sawing equipment for processing round steel for couplings. Through the setting of a fixed mechanism and a clamping plate, the fixed plate and the movable plate drive the corresponding clamping plate to clamp on both sides to achieve automatic centering of a single round steel. This restricts the four radial degrees of freedom (up, down, left, and right). The bakelite material does not damage the surface of the round steel. At the same time, it increases the coefficient of friction and enhances the anti-slip and anti-rotation effects, thereby reducing the probability of slight movement of the round steel. In addition, after the clamping plate clamps the corresponding round steel, there is a gap between adjacent round steels, which makes it difficult for the vibration generated when the round steel is sawed to be directly transmitted to adjacent round steels, thereby further reducing the probability of slight movement of the round steel.

[0015] By setting up a peeling mechanism, before the cutter cuts the round steel, the friction component rubs against the upper side of the round steel to be cut, removing the hard oxide scale points in the sawing area. This eliminates the impact and wear of the hard points on the cutter, significantly extending the cutter's life, reducing tooth breakage and uneven wear, and preventing end face tilting and roughness deviations caused by cutter wear. At the same time, it eliminates sudden changes in cutting force and sawing chatter caused by oxide scale, keeping the cutting force stable throughout the process and making sawing smoother. This reduces the probability of slight movement of the round steel and maintains the sawing accuracy of the round steel.

[0016] By setting up a preheating mechanism, the induction heating coil rapidly heats the sawing area of ​​the round steel before the cutter contacts it, causing the material in the sawing area to soften slightly and the cutting resistance to decrease. This further reduces the probability of slight movement of the round steel due to cutting vibration. At the same time, preheating will further loosen the residual oxide scale, further improving the sawing stability and end face quality. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0021] Example 1: Please refer to Figures 1-7 A batch sawing equipment for processing round steel for couplings includes a worktable 1. A fixing mechanism 2 is provided on the upper side of the worktable 1. The fixing mechanism 2 includes a fixed plate 20 and a movable plate 21. The fixed plate 20 is fixedly installed on the right side of the upper side of the worktable 1, and the movable plate 21 is slidably disposed on the left side of the upper side of the worktable 1. A sawing mechanism 3 is provided on the side of the fixed plate 20 facing away from the movable plate 21. The sawing mechanism 3 includes a sawing table 30 and a cutter 31. The sawing table 30 is fixedly connected to the worktable 1. The cutter 31 (with its own power source) is provided on the side of the sawing table 30 facing the fixed plate 20. The sawing table 30 drives the cutter 31 to move up and down. A through slot 4 is longitudinally opened in the interior of the worktable 1 and the interior of the fixed plate 20 corresponding to the position of the cutter 31. For the passage of the cutter 31, clamping plates 5 are fixedly installed on the opposite sides of the fixed plate 20 and the movable plate 21. The clamping plates 5 are in pairs, and two sets of clamping plates 5 on the same horizontal line clamp the round steel together (when two sets of clamping plates 5 in the horizontal direction clamp the round steel together, there is a gap between the round steel and the movable plate 21 (the distance between the closest ends of the clamping plates 5 in the group). When the cutter 31 cuts the round steel, the cutter 31 does not contact the movable plate 21 through the setting of this gap, avoiding impact damage between the movable plate 21 and the cutter 31). The clamping plates 5 are set with an inclined structure. Each set of clamping plates 5 is symmetrical about the corresponding round steel. Two sets of clamping plates 5 on the same horizontal line are symmetrical about the corresponding round steel. There is a gap between each set of clamping plates 5 adjacent in the longitudinal direction.

[0022] In use, bring the movable plate 21 close to the fixed plate 20 so that the clamping plates 5 on their opposite sides are close together. Then, insert the round steel into the inner side of the horizontally close clamping plates 5. (At this time, the minimum distance between the ends of the two sets of clamping plates 5 in the horizontal direction is less than the diameter of the round steel, so that after the round steel is inserted between the clamping plates 5, it will be blocked by the lower clamping plate 5, thus preventing the round steel from falling and affecting the sawing operation. The space inside the clamping plate 5 is larger than the cross-sectional area of ​​the round steel, so the clamping plate 5 does not clamp the round steel tightly at this time, thus facilitating the adjustment of the longitudinal direction.) After aligning the round steel bars, the movable plate 21 approaches the fixed plate 20 at its limit, causing the round steel bars to move upward and be clamped and fixed by the clamping plate 5. The clamping plates 5 on both sides of the horizontally corresponding plates achieve automatic centering of a single round steel bar, restricting the four radial degrees of freedom in the up, down, left, and right directions, thereby reducing the probability of slight movement of the round steel bars. In addition, after the clamping plate 5 clamps the corresponding round steel bars, there is a gap between adjacent round steel bars, which makes it difficult for the vibration generated when the round steel bars are sawed to be directly transmitted to adjacent round steel bars, thereby further reducing the probability of slight movement of the round steel bars. Afterwards, the cutter 31 rotates at high speed, and the sawing table 30 drives the cutter 31 into the through slot 4, and cuts the longitudinally arranged round steel bars from top to bottom. After the round steel bars are cut, the movable plate 21 moves away from the fixed plate 20 by a small distance, so that the cut round steel bars are still in the space inside the clamping plate 5, but are not clamped. Then, the round steel bars are taken out by the external robotic arm (the robotic arm clamps one end of the fixed round steel bars and then pulls the round steel bars out horizontally). Then, the clamping cylinder 23 retracts, driving the movable plate 21 and the corresponding clamping plate 5 to move back to their original positions. The sawing table 30 drives the cutter 31 to move up and reset.

[0023] Please see Figures 1-7 The fixing mechanism 2 also includes a fixing platform 22 and a clamping cylinder 23. The fixing platform 22 is fixedly installed on the upper side of the workbench 1 and at the position where the movable plate 21 faces away from the fixing plate 20. The clamping cylinder 23 is fixedly installed inside the fixing platform 22. The telescopic rod of the clamping cylinder 23 is fixedly connected to the movable plate 21. The clamping plate 5 is made of wear-resistant bakelite.

[0024] The clamping cylinder 23 drives the movable plate 21 to move, while the bakelite material does not damage the surface of the round steel (bakelite is a high-molecular composite material, with a hardness far lower than carbon steel and alloy steel. When in contact with the round steel, it hardly produces scratches, indentations, or tears on the surface of the round steel; bakelite has a certain degree of elasticity, and when in contact with the round steel, it will produce a slight deformation and fit, unlike metal-to-metal contact which will produce hard compression or scraping, thus providing a flexible clamping; the internal structure of bakelite is uniform and does not contain hard particles, so it will not cause abrasive wear on the surface of the round steel), while increasing the coefficient of friction and enhancing the anti-slip and anti-rotation effects (bakelite has a high static coefficient of friction with steel, which is relatively stable). Under the same clamping force, the friction is much greater than that between steel and steel, which can significantly improve the ability to prevent axial movement and circumferential rotation. When the bakelite is compressed, it will deform slightly and fit more tightly with the outer circle of the round steel, increasing the actual contact area and further improving the friction. The bakelite is non-reflective, non-smooth, and does not produce a mirror effect, making it less likely to slip with the round steel and providing stronger resistance to the torsional and cutting forces generated during sawing. Small particles of oxide scale from the round steel will be slightly embedded in the bakelite, without forming a ball effect, but instead further improving the frictional engagement and maintaining high anti-slip ability, thereby further reducing the probability of slight movement of the round steel.

[0025] Example 2: Please refer to Figures 1-7 A peeling mechanism 6 is provided on the upper side of the round steel. The peeling mechanism 6 includes a friction element 60. The friction element 60 and the clamping plate 5 correspond to different positions of the round steel. The inner diameter of the friction element 60 is the same as the diameter of the round steel. A screw (driven by a motor to rotate) is provided inside the movable plate 21 corresponding to the position of the friction element 60. The screw and the connecting block of the friction element 60 form a transmission connection.

[0026] When the round steel bar is inserted into the inner side of the horizontally close clamping plate 5, the round steel bar is located below the friction element 60. Then, the screw drives the friction element 60 to move to the middle of the round steel bar to be sawed. Then, the movable plate 21 approaches the fixed plate 20 at its limit, so that the round steel bar is clamped and fixed by the clamping plate 5. At this time, the round steel bar is located at the center of the inner side of the two sets of horizontal clamping plates 5, so that the round steel bar is pressed against the friction element 60 upwards. (Because the set of clamping plates 5 is an inclined straight plate structure, when the two sets of horizontal clamping plates 5 approach each other at their limit, the round steel bar is subjected to the continuously approaching lower clamping force.) The thrust of the clamping plate 5 causes it to slide upward along the surface of the lower clamping plate 5, and then to adhere upward to the friction element 60 (if the clamping plate 5 is a longitudinal straight plate or an arc plate, it can only apply horizontal radial pressure to the round steel, causing the round steel to move horizontally, but cannot achieve the upward movement of the round steel)). Through the upward adhesion of the round steel, the contact force between the friction element 60 and the round steel is increased, which increases the friction force of the subsequent friction element 60 on the oxide scale, resulting in a better removal effect of oxide scale in the upper area of ​​the subsequent round steel sawing zone (the starting end of the friction element 60 can be set near...). Near the movable plate 21, the end point of the friction element 60 extends along the surface of the round steel towards the fixed plate 20, making the friction point of the friction element 60 closer to the cutter 31 (the cutter 31 is located closer to the fixed plate 20). This increases the contact area between the cutter 31 and the clean area of ​​the round steel surface, resulting in smoother sawing and reduced dimensional deviations caused by chatter. Then, the screw drives the friction element 60 to move axially (the axial reciprocating range is 10-20 mm), reducing the oxygen content at the sawing position on the upper side of the round steel. The oxide scale is removed by friction, thereby eliminating the hard oxide scale points in the sawing area. This eliminates the impact and wear of the hard points on the cutter 31, significantly extending the life of the cutter 31, reducing tooth breakage and uneven wear, and preventing end face tilting and roughness deviations caused by cutter 31 wear. It also eliminates sudden changes in cutting force and sawing chatter caused by oxide scale, ensuring stable cutting force throughout the process, resulting in smoother sawing and reducing dimensional deviations and end face ripples caused by chatter. Furthermore, it reduces sawing cutting resistance and simultaneously reduces the torsional and lifting forces of the cutter 31 on the round steel, decreasing the probability of slight movement of the round steel. After the friction is complete, the screw rotates and drives the friction component 60 to reset. The reset friction component 60 keeps pressing the round steel, thereby further reducing the probability of the round steel moving upward and maintaining the sawing accuracy of the round steel.

[0027] Please see Figures 1-7 The peeling mechanism 6 also includes an accumulation groove 61. An accumulation groove 61 is provided on both sides of the inner side of the friction member 60 along the axial direction. The depth of the accumulation groove 61 is in millimeters (see attached diagram). The depth of the accumulation groove 61 gradually increases from the opening inward.

[0028] When the aforementioned friction element 60 reciprocates axially against the upper area of ​​the round steel sawing zone, the oxide scale that is rubbed off will enter the accumulation groove 61. Since the accumulation groove 61 is designed with a small opening and a large body, the oxide scale particles that enter it are more likely to be retained in it. As a result, when the friction element 60 is reset, the oxide scale particles accumulated in the accumulation groove 61 form a "micro-friction layer" (the oxide scale particles themselves have high hardness and large roughness, and after accumulation, they form a natural high friction damping layer). This automatically increases the friction force and anti-torsion resistance between the friction element 60 and the round steel (the particles are tightly bound, increasing the normal pressure of the friction element 60 on the round steel, and the particles bite the surface of the round steel, greatly improving the circumferential anti-torsion resistance), reducing the probability of slight movement of the round steel and maintaining the sawing accuracy of the round steel.

[0029] Please see Figures 1-7 The peeling mechanism 6 also includes a baffle 62. The baffle 62 is fixedly installed on the inner wall of the opening of the accumulation tank 61. The baffle 62 is made of flexible material and the cross-sectional area of ​​the baffle 62 is smaller than the cross-sectional area of ​​the opening of the accumulation tank 61.

[0030] By setting up the flexible baffle 62, when the oxide scale particles that have been rubbed off enter the accumulation tank 61, they will be subjected to the relative pressure of the friction element 60 and the oxide scale that has not been rubbed off, thereby squeezing the flexible baffle 62 and entering the accumulation tank 61. When the oxide scale particles want to leave the accumulation tank 61, they can only resist the deformation force of the flexible baffle 62 by the friction force with the surface of the round steel (at this time, the oxide scale particles are separated from the surface of the round steel). This makes the baffle 62 block most of the oxide scale particles, so that the oxide scale particles accumulate in the accumulation tank 61, thereby forming a reinforced friction layer, reducing the probability of slight movement of the round steel, and maintaining the sawing accuracy of the round steel.

[0031] The friction element 60 is a grinding block of silicon carbide abrasive and nylon matrix, the baffle 62 is made of wear-resistant rubber, and the inner surface of the accumulation groove 61 is made of micro-rough texture.

[0032] The grinding blocks are made of silicon carbide abrasive and nylon matrix, which can efficiently remove oxide scale without scratching the round steel matrix and affecting subsequent processing. The inner wall of the accumulation groove 61 with micro-rough texture can further retain oxide scale particles.

[0033] Example 3: Please refer to Figures 1-7A preheating mechanism 7 is provided on the outer side of the round steel. The preheating mechanism 7 includes a preheating source 70 and an induction heating coil 71. The preheating source 70 is located on the upper side of the round steel. The preheating source 70 and the clamping plate 5 correspond to different positions of the round steel. The preheating source 70 and the friction element 60 are symmetrically arranged with the cutter 31 as the center. The induction heating coil 71 is sleeved on the outer side of the round steel. The inner diameter of the induction heating coil 71 is larger than the diameter of the round steel. The induction heating coil 71 and the preheating source 70 are electrically fixedly connected. A screw (driven by a motor to rotate) is provided inside the movable plate 21 corresponding to the position of the preheating source 70. The screw and the connecting block of the preheating source 70 form a transmission connection (the same arrangement as the friction element 60).

[0034] When the round steel bar is inserted into the horizontally close inner position of the clamping plate 5, the round steel bar is in an eccentric position inside the induction heating coil 71. Then, when the movable plate 21 approaches the fixed plate 20 at its limit, so that the round steel bar is clamped and fixed by the clamping plate 5, the round steel bar is in the center position inside the induction heating coil 71. Then, during the process of the sawing table 30 driving the rotating cutter 31 to cut the round steel bar downwards, the screw first drives the preheating source 70 and the induction heating coil 71 to move (the longitudinally arranged induction heating coil 71 moves in sequence). Since the friction block 60 moves first and the induction heating coil 71 moves later, the oxide scale removed by the friction block 60 is less likely to fall onto the induction heating coil 71, thereby maintaining the cleanliness of the induction heating coil 71. The heating effect, along with the preheating of the round steel before the friction removal of the oxide scale, avoids the problem of high surface temperature of the round steel and easy wear of the friction block 60 during heating. This causes the induction heating coil 71 to move to the round steel sawing area and quickly (within one second, 200-350℃, which will slightly soften the steel at the sawing position, but due to the heating time, it avoids the heat from spreading outward and avoids the clamping operation of the clamping plate 5 being affected by the heat) heats the sawing area of ​​the round steel, which slightly softens the material in the sawing area and reduces the cutting resistance, thereby further reducing the probability of slight movement of the round steel due to cutting vibration. At the same time, the preheating will further loosen the residual oxide scale, further improving the sawing stability and end face quality. In addition, since the oxide scale on the upper side of the round steel sawing area is removed in advance by the friction component 60, the induced heat of the induction heating coil 71 can more easily act directly on the round steel without being wasted on the oxide scale, resulting in higher heating efficiency. Afterwards, the induction heating coil 71 stops operating, the screw drives the preheating source 70 and the induction heating coil 71 to reset, and then the cutter 31 cuts the preheated round steel.
