Description

Technical Field

[0001] This invention relates to a manufacturing process, and more particularly to a manufacturing process for a large circular blade for dismantling waste tires, applicable to the field of waste recycling. Background Technology

[0002] With the rapid development of the automobile industry, the number of waste tires generated each year is also increasing. In the past, waste tires were simply thrown away as garbage, which not only wasted resources but also polluted the environment. As a result, people have begun to pay attention to the recycling and reuse of waste tires.

[0003] When recycling and reusing tires, some unusable waste tires usually need to be cut and disassembled using a slitting machine. The large circular blade is the tool used on the slitting machine to cut the tires.

[0004] In the manufacturing process of large circular cutters, multiple circular holes for connection and installation need to be machined on the blank. Since the blank has annular cutting edges on its outer circumference, and the blank needs to be fixed during punching, traditional manufacturing processes typically use clamping. This direct stress on the cutting edges can easily damage them, affecting the quality of the finished large circular cutter. Therefore, we propose a manufacturing process for large circular cutters used in waste tire dismantling. Summary of the Invention

[0005] The technical problem to be solved by the present invention in view of the above-mentioned prior art is that in the traditional manufacturing process, when machining mounting holes on the blank, the cutting edge on the blank is easily damaged due to excessive force, which affects the quality of the finished large circular cutter.

[0006] To address the above problems, this invention provides a manufacturing process for a large circular blade used in the dismantling of waste tires, comprising the following steps:

[0007] S1. Select cemented carbide as the material and manufacture the blank of the large round knife through casting process;

[0008] S2. Perform finishing on the blank to process the blank into a finished blank. The finished blank consists of a hole-set cutter body and a cutting edge cutter body. The hole-set cutter body is annular, and the cutting edge cutter body is sleeved on the outside of the hole-set cutter body and has a cutting edge on the outer circle of the cutting edge cutter body.

[0009] S3. Heat treatment of the blank;

[0010] S4. Use a protective punching device to machine multiple mounting holes on the hole-setting cutter body in the blank;

[0011] S5. Clean the burrs generated by punching on the blank to obtain the finished large round knife.

[0012] The blade guard punching device includes a punching mechanism and a blade guard blank fixing assembly. The punching mechanism includes a base, on which a support frame is fixedly installed. A punching machine is mounted on the support frame, and a punching die head is fixedly connected to the output end of the punching machine. The blade guard blank fixing assembly includes a cylindrical fixed punching table fixedly installed on the base. The cylindrical fixed punching table is a hollow cylinder. A cylinder is fixedly installed inside the cylindrical fixed punching table. A piston plate matching the cylindrical fixed punching table is fixedly connected to the output end of the cylinder. The piston plate is slidably sealed to the inner wall of the cylindrical fixed punching table. Multiple blank suction holes evenly distributed in a ring are opened on the top outer wall of the cylindrical fixed punching table.

[0013] In the above-mentioned manufacturing process of large circular cutters for waste tire dismantling, when machining mounting holes on the blank, the cutting edge on the blank will not be directly subjected to force, thus preventing damage to the cutting edge and indirectly improving the quality of the finished large circular cutter.

[0014] As a further improvement of this application, a guide tube is embedded through the top outer wall of the cylindrical solid punching platform. The top of the guide tube is flush with the top of the cylindrical solid punching platform and is located directly below the punching die. A waste discharge pipe is embedded through the side wall of the cylindrical solid punching platform.

[0015] As a further improvement of this application, the waste discharge pipe is set in an inclined shape with the left side higher than the right side. The bottom end of the conduit is connected to the waste discharge pipe, and the left end of the waste discharge pipe is set in a sealed shape, so that the waste generated by punching can be discharged easily and is not easy to block.

[0016] As a further improvement of this application, a blank holder is fixedly installed at the top of the cylindrical punching station. The diameter of the blank holder matches the inner diameter of the punching cutter body, so that the blank holder can play a positioning role for the blank, which is beneficial to improving the accuracy of punching.

[0017] As another improvement of this application, the blade-protecting punching device also includes a linkage reinforcement component. The linkage reinforcement component includes a sealing insert that penetrates and is embedded in the outer wall of the top of the cylindrical fixed punching platform. Pressure regulating cylinders are embedded in the outer walls of both the left and right sides of the sealing insert. A pressure regulating plate is provided inside the pressure regulating cylinder and is slidably and sealingly connected to it. An elastic sealing membrane is embedded in the outer wall of the top of the pressure regulating cylinder, and a fixed blank reinforcement rod is embedded in the middle of the elastic sealing membrane.

[0018] As a further improvement to this application, the top of the sealing insert is set to be open, the end of the pressure regulating cylinder located outside the sealing insert is set to be open, and a pressure regulating rod is fixedly connected between the pressure regulating plate and the blank fixing rod. One end of the blank fixing rod is set to be an arc surface that matches the inner ring of the hole-setting cutter body, which can further improve the fixing effect on the blank.

[0019] As another improvement of this application, a rotating motor is fixedly installed on the support frame, the punching machine is fixedly installed on the output end of the rotating motor, and a punching intelligent controller and a punching start button are fixedly installed on the base. The punching intelligent controller is equipped with a hole number setting module, a degree calculation module, and a punching control module.

[0020] As a further improvement to this application, the punch start button is electrically connected to the punching control module, the hole number setting module is electrically connected to the degree calculation module, the degree calculation module is electrically connected to the punching control module, and the punching control module is electrically connected to the punching machine, the rotating motor, and the cylinder, which can improve the automation and intelligence of the blade-protecting punching device.

[0021] In summary, the manufacturing process in this application uses a blade-guarding punching device to punch holes in the blank. The blade-guarding blank-fixing component within the punching device allows for effective fixation of the blank during mounting hole machining via suction generated by negative pressure. Compared to traditional clamping methods, the blade-guarding blank-fixing component prevents direct force on the cutting edge, thus avoiding damage and indirectly improving the quality of the finished large circular blade. Furthermore, the linkage reinforcement component ensures... Under negative pressure, the linkage reinforcement component also plays a role in fixing the blank, which not only further improves the fixing effect of the blank, but also prevents the blank from rotating unexpectedly during the punching process. Through the setting of the punching and rotation intelligent controller and the punching start button, the punching and rotation intelligent controller can automatically control the punching process. During the punching process, it will automatically and precisely adjust the rotation of the blank to continuously process the required number of mounting holes on the blank. This not only improves the automation and intelligence of the blade protection punching device, but also saves manpower and improves processing efficiency. Attached Figure Description

Detailed Implementation

[0034] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0035] First implementation method:

[0036] Figure 1-4 This paper illustrates a manufacturing process for a large circular blade used in the dismantling of waste tires, comprising the following steps:

[0037] S1. Select cemented carbide as the material and manufacture the blank of the large round knife through casting process;

[0038] S2. Perform finishing on the blank to process it into a finished blank. The finished blank consists of a hole-set cutter body 601 and a cutting edge cutter body 602 (the hole-set cutter body 601 and the cutting edge cutter body 602 are integrated, but the finished blank is divided into two parts for ease of expression). The hole-set cutter body 601 is annular, and the cutting edge cutter body 602 is fitted on the outside of the hole-set cutter body 601 and has a cutting edge on its outer circle.

[0039] S3. Heat treatment of the blank;

[0040] S4. Using a protective punching device, multiple mounting holes are machined on the hole-setting cutter body 601 in the blank.

[0041] S5. Clean the burrs generated by punching on the blank to obtain the finished large round knife.

[0042] Please see Figure 2-4 The blade guard punching device includes a punching mechanism and a blade guard blank fixing assembly. The punching mechanism includes a base 101, on which a support frame 102 is fixedly installed. A punching machine 103 is provided on the support frame 102. In this embodiment, the punching machine 103 is directly fixedly installed on the support frame 102. A punching die head 104 is fixedly connected to the output end of the punching machine 103. The blade guard blank fixing assembly includes a cylindrical fixed punching table 201 fixedly installed on the base 101. The cylindrical fixed punching table 201 is set as a hollow cylinder. A cylinder 202 is fixedly installed inside the cylindrical fixed punching table 201. A piston plate 203 matching the cylindrical fixed punching table 201 is fixedly connected to the output end of the cylinder 202. The piston plate 203 is slidably sealed to the inner wall of the cylindrical fixed punching table 201. Multiple suction holes 204 evenly distributed in a ring are opened on the top outer wall of the cylindrical fixed punching table 201.

[0043] Please see Figure 2-4 A guide tube 205 is embedded through the top outer wall of the cylindrical fixed punch 201. The top of the guide tube 205 is flush with the top of the cylindrical fixed punch 201 and is located directly below the punching die 104. A waste discharge pipe 206 is embedded through the side wall of the cylindrical fixed punch 201. The waste discharge pipe 206 is inclined with the left side higher than the right side. The bottom end of the guide tube 205 is connected to the waste discharge pipe 206. The left end of the waste discharge pipe 206 is sealed. During punching, the waste generated by punching will fall into the waste discharge pipe 206 through the guide tube 205. The blank is then slid outward along the waste discharge pipe 206, making it easy to discharge the waste generated by punching and preventing blockage. A fixed blank column 207 is fixedly installed at the top of the cylindrical fixed punching table 201. The diameter of the fixed blank column 207 matches the inner diameter of the hole setting cutter body 601. When placing the blank, the hole setting cutter body 601 can be sleeved on the fixed blank column 207 so that the punching position on the hole setting cutter body 601 can be accurately aligned with the punching die head 104. This allows the fixed blank column 207 to play a positioning role for the blank, which helps to improve the accuracy of punching.

[0044] Please see Figure 1-4When punching a blank using a protective punching device, mark the punching position on the punching cutter body 601, place the blank on the cylindrical fixed punching table 201, ensuring the punching cutter body 602 covers all the suction holes 204, and mount the punching cutter body 601 onto the fixed blank column 207. Align the punching die head 104 with a specific punching position, then start the cylinder 202, causing the piston plate 203 to move downwards a certain distance. This creates a negative pressure above the piston plate 203, generating a strong suction force at the suction holes 204 under the air pressure. This suction force effectively fixes the blank. Then, start the punching machine 103 to punch the blank. After one mounting hole is machined, the control cylinder 202 moves the piston plate 203 upward to reset, which restores the air pressure above the piston plate 203 to normal. Then, the precision blank is rotated and adjusted so that the punching die 104 is aligned with the next punching control. Punching continues until all mounting holes are machined. Therefore, by setting up the blade guard and blank fixing assembly, when machining mounting holes on the precision blank, the blade guard and blank fixing assembly can effectively fix the precision blank through the suction force generated by the negative pressure. Compared with the traditional clamping and fixing method, when the blade guard and blank fixing assembly fixes the precision blank, the cutting edge on the precision blank will not be directly subjected to force, thus preventing damage to the cutting edge and indirectly improving the quality of the finished large circular cutter.

[0045] Second implementation method:

[0046] Figure 5-10This invention illustrates a manufacturing process for a large circular blade used in waste tire dismantling. Unlike the first embodiment, the blade-protecting punching device further includes a linkage reinforcement component. This component includes a sealing insert 301 embedded through the outer wall of the top of a cylindrical fixed punching platform 201. Pressure regulating cylinders 302 are embedded through the outer walls of both sides of the sealing insert 301. A pressure regulating plate 303 is slidably and sealingly connected to the pressure regulating cylinder 302. An elastic sealing membrane 304 is embedded through the outer wall of the top of the pressure regulating cylinder 302. A blank-fixing reinforcement rod 305 is embedded through the middle of the elastic sealing membrane 304. The top of the sealing insert 301... The pressure regulating cylinder 302 is configured as an open end outside the sealing insert 301. A pressure transmitting rod 306 is fixedly connected between the pressure regulating plate 303 and the billet reinforcing rod 305. In this embodiment, the top of the cylindrical fixed punching table 201 does not have a billet pillar 207, but the billet reinforcing rod 305 in the linkage reinforcing assembly can play the same positioning role as the billet pillar 207. When the blank is placed on the cylindrical fixed punching table 201, the hole-setting cutter body 601 in the blank can be sleeved on the outside of the two billet reinforcing rods 305, so that the inner wall of the hole-setting cutter body 601 is aligned with the arc end on the billet reinforcing rod 305. When the cylinder 202 moves the piston plate 203 downwards, creating a negative pressure above the piston plate 203, the pressure regulating plate 303 will tend to slide outwards from the pressure regulating cylinder 302 under the action of air pressure. Since the billet reinforcing rod 305 abuts against the inner wall of the hole-setting cutter body 601, the pressure regulating plate 303 will not actually slide. However, under the force transmission, this tendency will cause the billet reinforcing rod 305 to apply a large pressure to the inner wall of the hole-setting cutter body 601, resulting in a large maximum static friction force between the billet reinforcing rod 305 and the hole-setting cutter body 601. The friction between the hole-setting cutter bodies 601 can prevent the blank from rotating. Therefore, by setting up the linkage reinforcement component, the linkage reinforcement component can also fix the blank under negative pressure. This not only further improves the fixing effect of the blank, but also prevents the blank from rotating accidentally during the punching process. In addition, after the cylinder 202 drives the piston plate 203 to move upward and reset, the pressure applied by the blank fixing rod 305 to the hole-setting cutter body 601 will also decrease after the air pressure above the piston plate 203 returns to normal. This makes it easier for the operator to rotate and adjust the blank and to remove the blank.

[0047] Please see Figure 5-7 and Figure 10A rotary motor 105 is fixedly installed on the support frame 102, and a punching machine 103 is fixedly installed on the output end of the rotary motor 105 (in the first embodiment, the punching machine 103 is directly fixedly installed on the support frame 102). A punching control device 004 and a punching start button 005 are fixedly installed on the base 101. The punching control device 004 is equipped with a hole number setting module, a degree calculation module, and a punching control module. The punching start button 005 is electrically connected to the punching control module, the hole number setting module is electrically connected to the degree calculation module, the degree calculation module is electrically connected to the punching control module, and the punching control module is electrically connected to the punching machine 103, the rotary motor 105, and the cylinder 202. After the blank is placed, the operator can set the hole number using the hole number setting module. The number of holes is set (by default, the mounting holes are evenly distributed along the ring on the hole-setting die body 601). The angle calculation module will automatically calculate the interval angle between the mounting holes based on the number of holes and feed the calculation result and the number of mounting holes to be processed back to the punching control module. Then, the operator can issue a command to the punching control module by pressing the trigger punch start button 005. After receiving the command, the punching control module will first start the cylinder 202, causing the cylinder 202 to drive the piston plate 203 downward to fix the blank. Then, the punching control module will start the punch press 103, causing the punch press 103 to drive the punching die head 104 to punch the blank to process the first mounting hole. Then, the punching control module will control the punch press 103 to drive the punching. The die head 104 moves downward, inserting the punching die head 104 into the first mounting hole (the distance the punching die head 104 moves downward driven by the press 103 will be less than the distance the punching die head 104 moves downward driven by the press 103 during punching; the punching die head 104 will be inserted into the first mounting hole, but will not penetrate through it). Then, the punching control module will start the rotating motor 105, causing the rotating motor 105 to rotate the press 103 and the punching die head 104 by a corresponding angle (the angle of rotation here is consistent with the calculation result of the degree calculation module). Then, the punching control module will control the press 103 to move the punching die head 104 upward to reset. Next, the punching control module will control the rotating motor 105 to move the press 103 upward to reset the die head 104. 103. The punching die head 104 reverses and resets. Then, the punching control module controls the punching machine 103 to punch, machining the second mounting hole on the blank. This process continues until the last mounting hole is completed. Then, the punching control module controls the cylinder 202 to move the piston plate 203 upwards to reset. Finally, the worker removes the punched blank. Therefore, through the settings of the punching controller 004 and the punch start button 005, the punching controller 004 can automatically control the punching process. During the punching process, it automatically and precisely adjusts the rotation of the blank to continuously machine the required number of mounting holes, thereby improving the automation and intelligence of the blade punching device.It can also save manpower and improve processing efficiency.

[0048] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this invention.
