Detailed Description of the Invention

[0038] In order to further explain the technical solution of the present invention, it will be elaborated in detail through specific embodiments below.

[0039] The present invention provides a processing method for a foldable and reinforced metal cage, including the following steps:

[0047] S8. Surface treatment: Spray paint the surface of the cage body after the inspection is completed.

[0048] Please refer to Figure 1-2 , the present invention provides a processing method for a foldable reinforced metal cage. The cutting and grinding integrated device 1 in step S1 includes a cutting table 11, a support arm 12, a motor part 13, a machine handle 14, a saw blade guard 15, a machine shaft 16, a cutting and grinding combination mechanism 17, an auxiliary support mechanism 18, and a protection mechanism 19. The rear part of the top surface of the cutting table 11 is elastically rotatably connected to the support arm 12 by a torsion spring hinge. The top end of the support arm 12 is screwed to the motor part 13. The top of the housing of the motor part 13 is provided with a machine handle 14. In the middle of the bottom surface of the machine handle 14, there is a first switch 14a, and at the tail of the bottom surface of the machine handle 14, there is a second switch 14b. Both the first switch 14a and the second switch 14b are in control connection with the motor part 13. The right part of the motor part 13 is screwed with a saw blade guard 15. The right end of the motor part 13 is provided with a machine shaft 16. The machine shaft 16 is installed inside the saw blade guard 15. The cutting and grinding combination mechanism 17 is installed on the surface of the machine shaft 16. The auxiliary support mechanism 18 is installed on the right side surface of the saw blade guard 15. The upper part of the surface of the saw blade guard 15 is installed with the protection mechanism 19.

[0049] Further explanation: The first switch 14a is a touch switch, and the second switch 14b is a toggle switch. The touch switch has the characteristic of turning on when pressed and stopping when released. When performing cutting operations, the first switch 14a is used for operation, which is more in line with the operation habits of traditional cutting equipment. The toggle switch can control the circuit to be normally open. When only performing grinding operations, the motor part 13 can be controlled to be normally open through the second switch 14b, which is more convenient for grinding operations. Users can choose to use different switches according to the working conditions.

[0050] Please refer to Figure 3-5, the present invention provides a processing method for a foldable reinforced metal cage. The cutting and grinding combined mechanism 17 includes a cutting blade 171, a grinding wheel 172, and a first end cover 173. The cutting blade 171 is sleeved and installed on the left part of the surface of the machine shaft 16, and the grinding wheel 172 is sleeved and installed on the right part of the surface of the machine shaft 16. The grinding wheel 172 is kept in close contact with the side surface of the cutting blade 171. The end of the machine shaft 16 is sleeved and installed with the first end cover 173. The first end cover 173 is locked and fixed to the end of the machine shaft 16 by bolts. The first end cover 173 is kept in close contact with the side surface of the grinding wheel 172.

[0051] When using the cutting and grinding integrated device 1 to perform cutting and grinding operations on the stainless steel pipe, first connect the motor part 13 to an external power source, then place the stainless steel pipe on the top of the cutting table 11 and adjust the cutting position. Subsequently, hold the machine handle 14 and press the first switch 14a to start the motor part 13. The motor part 13 drives the cutting blade 171 and the grinding wheel 172 to rotate synchronously through the machine shaft 16. Then, press down and turn over the cutting blade 171 with the machine handle 14 to make the cutting blade 171 cooperate with the cutting table 11 to cut the stainless steel pipe, thereby realizing the cutting action. Finally, pick up the cut stainless steel pipe and bring the cut surface of the stainless steel pipe close to the grinding wheel 172 to grind and remove the burrs, thereby realizing the grinding action. The cutting and grinding integrated device 1 integrates cutting and grinding functions, can provide burr grinding treatment after the pipe is cut, improves the process continuity, and ensures the production and processing efficiency.

[0052] Furthermore, a rubber washer 172a is adhesively provided on the back surface of the grinding wheel 172. The grinding wheel 172 is in close contact with the surface of the cutting blade 171 through the rubber washer 172a. The rubber washer 172a can fill the gap between the grinding wheel 172 and the cutting blade 171, keep the grinding wheel 172 and the cutting blade 171 firmly connected, prevent loosening caused by vibration, and ensure the stable operation of the equipment.

[0053] Furthermore, the end of the machine shaft 16 can be sleeved and installed with a second end cover 174. The second end cover 174 is locked and fixed to the end of the machine shaft 16 by bolts. The second end cover 174 is a thickened version of the first end cover 173. The second end cover 174 can be kept in close contact with the side surface of the cutting blade 171. If the user chooses not to install the grinding wheel 172, the second end cover 174 can be used to cooperate with the cutting blade 171 for installation, and the grinding wheel 172 can be selected and installed according to the actual working conditions, providing more assembly options.

[0054] Please refer to Figure 6-7, the present invention provides a processing method for a foldable reinforced metal cage. The auxiliary support mechanism 18 includes a spline shaft 181, a threaded hole 182, a connecting arm 183, a tooth groove 184, a mounting bolt 185 and a bracket 186. The spline shaft 181 is screwed and installed at the rear edge of the right side surface of the saw blade guard 15. A threaded hole 182 is opened at the center of the right end of the spline shaft 181. A tooth groove 184 is opened at the left part of the rear end of the connecting arm 183. The connecting arm 183 is sleeved outside the spline shaft 181 through meshing of the tooth groove 184. A mounting bolt 185 is rotatably installed at the right part of the rear end of the connecting arm 183. The screw part of the mounting bolt 185 extends into the inner side of the tooth groove 184. The mounting bolt 185 can be threadedly connected with the inside of the threaded hole 182. The front end of the connecting arm 183 is connected with a bracket 186.

[0055] When the user holds the stainless steel pipe and performs grinding operation on the surface of the grinding wheel 172, the auxiliary support mechanism 18 can provide the bracket 186 as the bottom support for the stainless steel pipe, thereby improving the grinding operation efficiency of the stainless steel pipe. When disassembling, replacing or installing the cutting and grinding combination mechanism 17, by turning the mounting bolt 185 to screw it out from the inside of the threaded hole 182 and releasing the connection and fixation between the spline shaft 181 and the tooth groove 184, the connecting arm 183 can be removed from the outside of the spline shaft 181, and the disassembly of the bracket 186 can be completed, which can provide a larger installation space for the cutting and grinding combination mechanism 17 and will not interfere with the normal disassembly and replacement of the cutting and grinding combination mechanism 17.

[0056] Further explanation, the number of key teeth on the surface of the spline shaft 181 is not less than 24, and the shape and specifications of the tooth groove 184 match those of the spline shaft 181 to ensure the angle adjustment accuracy of the bracket 186, so that the user can adjust the installation angle of the bracket 186 according to his own operation habits.

[0057] Please refer to Figure 8-9 , the present invention provides a processing method for a foldable reinforced metal cage. The protection mechanism 19 includes an arc-shaped guide groove 191, a movable housing 192, a connecting rail 193 and a positioning bolt 194. The arc-shaped guide grooves 191 are symmetrically arranged on the upper parts of the left and right side surfaces of the saw blade guard 15. A movable housing 192 is sleeved on the surface of the saw blade guard 15. The connecting rails 193 are symmetrically arranged on the left and right side walls inside the movable housing 192. The connecting rails 193 are slidably matched with the inner sides of the arc-shaped guide grooves 191 to establish a sliding connection between the movable housing 192 and the saw blade guard 15. A positioning bolt 194 is threadedly screwed into the screw hole at the tail end of the right wall surface of the movable housing 192. The screw part of the positioning bolt 194 is threadedly screwed into the inside of the movable housing 192 and abuts against the saw blade guard 15, thereby frictionally locking the movable housing 192 in the current position.

[0058] When only the grinding operation is to be performed, first loosen the positioning bolt 194 to restore the movable cover 192 to its movable state, then slide the movable cover 192 downward along the arc-shaped guide groove 191 until the movable cover 192 flips to the lower part of the saw blade guard 15, and then tighten the positioning bolt 194 to lock the movable cover 192 in the current position. The movable cover 192 can cooperate with the saw blade guard 15 to block the cutting blade 171, preventing the user from contacting the rotating cutting blade 171 during the grinding operation, thus ensuring safety. Subsequently, press the second switch 14b to control the motor unit 13 to be normally open, facilitating the user to free both hands for the grinding operation.

[0059] Furthermore, the movable cover 192 and the saw blade guard 15 are made of the same material to ensure the protective ability of the movable cover 192.

[0060] The above are only the preferred examples of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
