Description

Technical Field

[0001] The invention relates to the field of steel ring forming, in particular to a jointless thin steel ring forming device and a forming process thereof. Background Art

[0002] Steel is a material of a certain shape, size and performance made from ingots, billets or steel through pressure processing. Most steel processing is done through pressure processing, which causes plastic deformation of the processed steel. Depending on the steel processing temperature, it can be divided into cold processing and hot processing.

[0003] In processing steel into ultra-thin steel rings, the long strip raw material needs to be cut according to the required diameter of the steel ring first, and then the cut raw material is formed into a ring through a winding device. After the ring is formed, the two ends of the cut raw material are connected and welded through a welding device. When the raw material is welded, the semi-finished product needs to be removed from the ring forming device, and then the semi-finished product is placed in a grinding device to complete the grinding of the inside and outside of the welding joint, so as to improve the strength of the steel ring.

[0004] In the prior art, in order to improve the strength of the ultra-thin steel ring, the welding joints of the formed steel ring need to be polished. At this time, the welded semi-finished product needs to be removed from the welding device, and then the welded semi-finished product needs to be placed in the polishing device. Then, the polishing device is started to polish the welding joints of the inner and outer walls of the semi-finished steel ring, thereby improving the strength of the ultra-thin steel ring. In the prior art, when polishing the welding joints of the ultra-thin steel ring, professional operators need to be arranged during the transportation of the semi-finished product, thereby reducing work efficiency. Summary of the invention

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a jointless thin steel ring forming device and a forming process thereof, comprising a base, a ring forming mechanism is arranged at the end of the base, and the ring forming mechanism comprises a ring forming bin, a second motor, a transmission mechanism, a feeding mechanism, a first fixing mechanism and a ring forming cylinder, the ring forming bin is arranged at the end of the base, and the second motor is arranged at the outside of the ring forming bin, the transmission mechanism is arranged at the inside of the ring forming bin, and the feeding mechanism is arranged at the outside of the transmission mechanism, the first fixing mechanism is arranged above the ring forming bin, and the ring forming cylinder is arranged at the outside of the transmission mechanism.

[0007] By adopting the above technical scheme, the transmission mechanism is rotated by starting the second motor, ensuring that the unloading mechanism is driven forward, thereby ensuring the horizontal movement of the formed semi-finished product. The first fixing mechanism is started to ensure that the raw material and the ring-forming cylinder are in contact. At the same time, the ring-forming cylinder is rotated by the rotation of the transmission mechanism, thereby completing the ring-forming of the raw material and ensuring the preliminary processing of the raw material.

[0011] By adopting the above technical scheme, the third gear is rotated through the transmission of the transmission pulley, thereby ensuring the rotation of the threaded sleeve. The threaded connection between the threaded sleeve and the threaded rod ensures the horizontal movement of the threaded rod on the inner side of the threaded sleeve. The horizontal movement of the threaded rod ensures the horizontal movement of the extrusion block. The threaded rod fits the outer wall of the ring-forming cylinder to ensure the pushing of the semi-finished product on the outer side of the ring-forming cylinder.

[0012] The present invention is further configured such that the first fixing mechanism includes a second cylinder, a transmission rod and an extrusion plate, and the second cylinder is arranged at the top end of the ring forming warehouse, the transmission rod is arranged below the second cylinder, and the extrusion plate is arranged at the bottom end of the transmission rod.

[0013] By adopting the above technical solution, the second cylinder is started, so that the transmission rod drives the extrusion plate to move downward, thereby ensuring that the end of the steel strip is squeezed and the end of the steel strip is in contact with the outer wall.

[0014] The present invention is further configured such that a grinding mechanism is provided at the end of the ring-forming cylinder, and the grinding mechanism includes an inner wall grinding mechanism, an outer roller, a first one-way gear, a second one-way gear, a fourth gear and a fixing mechanism, the inner wall grinding mechanism is arranged at the end of the ring-forming cylinder, and the outer roller is arranged on the outside of the inner wall grinding mechanism, the first one-way gear is arranged on one side of the second gear, and the second one-way gear is arranged on the other side of the second gear, the fourth gear is arranged on the outside of the second one-way gear, and the second fixing mechanism is arranged on the outside of the outer roller.

[0015] By adopting the above technical scheme, the first one-way gear is rotated by the rotation of the second gear, and the meshing connection between the first one-way gear and the inner wall grinding mechanism ensures that the inner wall grinding mechanism rotates, thereby completing the grinding of the inner wall of the semi-finished product. The second one-way gear is rotated by the rotation of the second gear, ensuring the rotation of the fourth gear, ensuring that the inner wall grinding mechanism is driven to rotate, thereby ensuring the grinding of the inner wall of the semi-finished product. The setting of the second fixing mechanism ensures that the outer drum is fixed to the outside of the semi-finished product, thereby ensuring the grinding of the outer wall of the semi-finished product.

[0017] By adopting the above technical solution, the meshing connection between the first one-way gear and the gear ring ensures that the inner drum rotates, thereby completing the grinding of the inner wall of the semi-finished product. By arranging the grinding roller on the outer side of the inner drum, it is ensured that when the inner drum rotates, the grinding roller is in contact with the semi-finished product, and the grinding roller rotates, thereby completing the grinding of the inner wall of the semi-finished product.

[0018] The present invention is further configured such that the inner roller is connected to the ring forming roller by a bearing, and the grinding roller is connected to the inner roller by a bearing, the second gear is meshingly connected to the first one-way gear and the second one-way gear respectively, and the second one-way gear is meshingly connected to the fourth gear, the fourth gear is meshingly connected to the gear ring, and the first one-way gear is meshingly connected to the gear ring.

[0019] By adopting the above technical scheme, the bearing connection between the inner roller and the ring forming roller ensures that when the ring forming roller rotates, the inner roller will not rotate. The bearing connection between the inner roller and the grinding roller ensures that when the inner roller rotates, the grinding roller drives the grinding roller to form a circular motion. The fit between the grinding roller and the semi-finished product ensures that the grinding roller grinds the inner wall of the semi-finished product. The meshing connection between the second gear and the first one-way gear ensures that when the second gear rotates forward, the first one-way gear rotates, thereby ensuring that the grinding roller rotates the inner roller. At this time, due to the one-way bearing set on the second one-way gear, the second one-way gear will not rotate. When the second gear is reversed, the second one-way gear is rotated, ensuring that the fourth gear is driven to rotate, thereby ensuring that the inner roller rotates, thereby completing the grinding of the inner wall of the semi-finished product.

[0020] The present invention is further configured as follows: the second fixing mechanism includes a fixing ring, a limiting ring and a connecting column, and the fixing ring is arranged on the outside of the outer drum, and the fixing ring and the outer drum are fixedly connected, a sliding groove is arranged on the outside of the fixing ring, and the limiting ring is arranged in the sliding groove on the outside of the fixing ring, and the limiting ring and the fixing ring are connected by the sliding groove, and the connecting column is arranged on the outside of the limiting ring, and the connecting column and the ring forming warehouse are fixedly connected.

[0021] By adopting the above technical solution, the support of the limit ring is ensured through the fixed connection between the connecting column and the ring forming bin, thereby ensuring the limiting of the fixed ring, thereby ensuring the limiting of the outer roller, and ensuring the grinding of the outer wall of the semi-finished product.

[0022] The present invention is further configured such that a storage mechanism is provided at the other end of the base, and a feeding mechanism is provided above the base, a cutting mechanism is provided on one side of the feeding mechanism, and an extrusion table is provided on the other side of the cutting mechanism, and a limiting mechanism is provided on the other side of the extrusion table.

[0023] By adopting the above technical scheme, the loading of the steel strip is ensured by the setting of the storage mechanism, the horizontal movement of the steel strip is ensured by the setting of the feeding mechanism, the cutting of the steel strip of the required length is ensured by the setting of the cutting mechanism, and the position of the steel strip during horizontal movement is limited by the setting of the limiting mechanism, thereby ensuring that the steel strip will not deviate.

[0024] A process for forming a jointless thin steel ring, using a ring forming machine for welding steel strips into rings, comprises the following steps:

[0025] Step 1: The raw material is sleeved on the outside of the first rotating shaft, and then the end of the steel belt is pulled so that the end of the steel belt passes through the two sets of rollers. At this time, the first motor is started to rotate the rollers, thereby ensuring that the steel belt passes through the friction of the two sets of rollers, so that the steel belt moves horizontally;

[0026] Step 2: When the end of the steel strip moves to the top of the cutting base, the two sets of rollers are continuously rotated to make the steel strip continuously move horizontally until one end of the steel strip moves to the inner side of the extrusion table, so that the steel strip continuously moves to the limiting mechanism. At this time, the end of the steel strip moves to the inner side of the limiting frame, and the steel strip is limited by the limiting frame to move horizontally;

[0027] Step 3: When the length of the steel strip reaches the required length, the first cylinder is started to move the cutting knife downward. At this time, the cutting knife cuts the steel strip. Through the continuous movement of the steel strip, the end of the steel strip moves to the outside of the ring-forming cylinder. At this time, the fixing mechanism makes the end of the steel strip fit with the ring-forming cylinder.

[0028] Step 4: The transmission mechanism is started to rotate the ring-forming drum, so that the steel strip is formed into a ring outside the ring-forming drum, and then the two ends of the steel strip are welded by an external welding device;

[0029] Step 5: The welded steel strip is pushed by the unloading mechanism to move the steel strip to the outside of the inner wall grinding mechanism. The inner wall grinding mechanism and the outer drum are rotated to form relative motion, thereby completing the simultaneous grinding of the inner and outer walls of the ring-shaped steel strip.

[0030] In summary, the present invention mainly has the following beneficial effects:

[0031] 1. The present invention is provided with a feeding mechanism, a cutting mechanism, an extrusion table, a limiting mechanism and a looping mechanism. By starting the first motor, the rollers are rotated, so that the two groups of rollers rotate at the same time. The rollers squeeze the steel strip, so that the steel strip moves horizontally along the rollers until the steel strip moves horizontally to the cutting mechanism. The rollers are continuously rotated to make the steel strip move horizontally continuously. At this time, the end of the steel strip moves to the inside of the limiting frame. When the stretched length of the steel strip reaches the circumference of the required steel ring, the first cylinder is started to move the cutting knife downward to cut the steel strip. The second cylinder is started to drive the extrusion plate downward to make the end of the steel strip fit the outer side of the looping cylinder. Then the second motor is started to rotate the second shaft, so that the looping cylinder rotates, so that the steel strip is looped.

[0032] 2. The present invention is provided with a ring-forming mechanism and a grinding mechanism. The second gear rotates forwardly through the forward rotation of the second rotating shaft. At this time, the rotation direction of the first one-way gear is single, thereby ensuring that the first one-way gear does not rotate. The second gear is meshed with the second one-way gear to rotate the second one-way gear, thereby rotating the fourth gear. The meshing connection between the fourth gear and the gear ring allows the inner roller to rotate. At this time, the gear ring performs circular motion with the inner roller. The gear ring and the inner roller are connected by a bearing, so that the gear ring grinds the inner wall of the steel belt. The rotation of the inner roller forms a relative motion between the inner roller and the outer roller, so that the outer roller grinds the outer wall of the steel belt.

[0055] A process for forming a jointless thin steel ring, using a ring forming machine for welding steel strips into rings, comprises the following steps:

[0056] Step 1: The raw material is sleeved on the outside of the first rotating shaft, and then the end of the steel belt is pulled so that the end of the steel belt passes through the two sets of rollers. At this time, the first motor is started to rotate the rollers, thereby ensuring that the steel belt passes through the friction of the two sets of rollers, so that the steel belt moves horizontally;

[0057] Step 2: When the end of the steel strip moves to the top of the cutting base, the two sets of rollers are continuously rotated to make the steel strip continuously move horizontally until one end of the steel strip moves to the inner side of the extrusion table, so that the steel strip continuously moves to the limiting mechanism. At this time, the end of the steel strip moves to the inner side of the limiting frame, and the steel strip is limited by the limiting frame to move horizontally;

[0058] Step 3: When the length of the steel strip reaches the required length, the first cylinder is started to move the cutting knife downward. At this time, the cutting knife cuts the steel strip. Through the continuous movement of the steel strip, the end of the steel strip moves to the outside of the ring-forming cylinder. At this time, the fixing mechanism makes the end of the steel strip fit with the ring-forming cylinder.

[0059] Step 4: The transmission mechanism is started to rotate the ring-forming drum, so that the steel strip is formed into a ring outside the ring-forming drum, and then the two ends of the steel strip are welded by an external welding device;

[0060] Step 5: The welded steel strip is pushed by the unloading mechanism to move the steel strip to the outside of the inner wall grinding mechanism. The inner wall grinding mechanism and the outer drum are rotated to form relative motion, thereby completing the simultaneous grinding of the inner and outer walls of the ring-shaped steel strip.

[0061] The working principle of the present invention is as follows: when the ultra-thin steel strip needs to be looped, the rolled ultra-thin steel strip is first placed on the chassis 201, and then the end of the steel strip 9 is pulled so that the end of the steel strip 9 passes between the two sets of rollers 303, and then the first motor 302 is started to rotate the rollers 303, so that the two sets of rollers 303 rotate at the same time, and the steel strip 9 is squeezed by the rollers 303 so that the steel strip 9 moves horizontally along the rollers 303 until the steel strip 9 moves horizontally to the cutting mechanism 4, and the steel strip 9 continues to move horizontally through the continuous rotation of the rollers 303, and at this time, the end of the steel strip 9 moves to the inner side of the limit frame 602, and when the stretched length of the steel strip 9 reaches the circumference of the required steel ring, the first cylinder 402 is started to move the cutting knife 403 downward, so that the steel strip 9 is cut;

[0062] Secondly, the end of the steel strip 9 moves to the top of the ring-forming cylinder 706, and then the second cylinder 7051 is started, so that the transmission rod 7052 drives the extrusion plate 7053 to move downward, so that the end of the steel strip 9 fits the outer side of the ring-forming cylinder 706, and then the second motor 702 is started to rotate the second shaft 7031, so that the ring-forming cylinder 706 rotates, so that the steel strip 9 is ringed, and after the ring is formed, the connection of the steel strip 9 is welded by an external welding device;

[0063] Furthermore, after welding is completed, the second motor 702 is reversed, so that the second rotating shaft 7031 drives the first gear 7032 to reverse, and the meshing connection between the second rotating shaft 7031 and the transmission belt 7033 causes the transmission belt 7033 to drive the third gear 7041 to rotate until the threaded sleeve 7042 rotates, and the threaded connection between the threaded sleeve 7042 and the threaded rod 7043, as well as the rotation of the threaded sleeve 7042, causes the threaded rod 7043 to push the extrusion block 7044 forward, and the extrusion block 7044 fits the outer wall of the ring-forming cylinder 706, so that the ring-forming steel belt 9 moves toward the direction of the grinding mechanism 8 until the steel belt 9 moves to the outside of the inner wall grinding mechanism 801;

[0064] Furthermore, the second gear 7034 rotates forwardly through the forward rotation of the second rotating shaft 7031. At this time, the rotation direction of the first one-way gear 803 is single, thereby ensuring that the first one-way gear 803 does not rotate. The second gear 7034 is meshed with the second one-way gear 804, so that the second one-way gear 804 rotates, thereby causing the fourth gear 805 to rotate. The meshed connection between the fourth gear 805 and the gear ring 8012 causes the inner drum 8011 to rotate. At this time, the gear ring 8012 performs a circular motion with the inner drum 8011. The gear ring 8012 and the inner drum 8011 are connected by a bearing, so that the gear ring 8012 grinds the inner wall of the steel belt 9, and the rotation of the inner drum 8011 , so that the inner roller 8011 and the outer roller 802 form a relative movement, so that the outer roller 802 grinds the outer wall of the steel belt 9. When the second rotating shaft 7031 reverses, the first one-way gear 803 rotates through the meshing connection between the second gear 7034 and the first one-way gear 803, and the first one-way gear 803 is meshed with the gear ring 8012, so that the inner roller 8011 rotates in the same direction, so that the inner wall grinding mechanism 801 and the first one-way gear 803 continue to grind the steel belt 9. At this time, the second one-way gear 804 has a single rotation direction, which ensures that the second one-way gear 804 will not rotate, thereby ensuring that the rotation direction of the inner wall grinding mechanism 801 is always the same, thereby completing the grinding of the welding port of the steel belt 9;

[0065] Finally, when the steel strip 9 is continuously processed, the unloading mechanism 704 continuously pushes the semi-finished steel strip 9 forward, so that the steel strips 9 are extruded with each other, so that the initially formed steel strip 9 is squeezed by the subsequent steel strip 9, so that the steel strip 9 moves horizontally on the outside of the inner roller 8011 and is continuously polished during the movement, so that the steel strip 9 is moved out of the device from the end of the grinder 8, thereby completing the processing of the ultra-thin steel ring.
