Description

Technical Field

[0001] The present invention relates to the technical field of mechanical manufacturing, and in particular to a metal cutting device and method for mechanical manufacturing. Background Art

[0002] The metal cutting device used in mechanical manufacturing refers to various tools and equipment used to process metal materials. Among them, the cutting machine is one of the commonly used equipment in the process of cutting metal plates. The metal plate is moved to the bottom of the cutting knife through the transmission mechanism, and the metal plate is divided into the required shape and size through the downward pressure of the cutting knife. Since a lot of heat will be generated on the surface of the metal plate when it is cut, in order to avoid damage to the metal plate caused by excessive heat, the surface of the metal plate will be cooled by cold water.

[0003] However, when the above-mentioned device uses cold water to cool the surface of the metal plate, the volume of the cold water spray is constant, and the water output during the cold water spray cannot be adjusted according to the different thicknesses of the metal plates. For thinner metal plates, too much cooling water may lead to waste of resources and increase the cost of processing cooling water. For thicker metal plates, the constant water output may not be enough to provide sufficient cooling effect, resulting in overheating of the cutting area, affecting the cutting quality and tool life.

[0048] The remaining structure is the same as that of Example 2.

[0049] Reference Figures 1 to 7 , which is the fourth embodiment of the present invention. This embodiment is different from the third embodiment in that: this embodiment provides a metal cutting device and method for mechanical manufacturing.

[0050] When it is necessary to cut the metal plate A, the staff places the metal plate A to be processed on the top of the support table 102. When the metal plate A moves to the bottom of the cutting mechanism 200 following the transmission mechanism 300, the first motor 204 can be started. The first motor 204 drives the threaded rod 203 to rotate on the top of the U-shaped plate 201. When the threaded rod 203 rotates, the threaded block 202 is driven to move forward and backward along the surface of the threaded rod 203 through the cooperation of the limit rod 206. At the same time, the electric push rod 207 can be started. The electric push rod 207 drives the mounting seat 208 to perform vertical height lifting, thereby driving the cutting disc 210 to rise to a suitable height and starting the second motor 209.

When the metal plate A is placed on top of the active roller 305 and the driven roller 306, the third motor 307 can be started. The third motor 307 drives the first rotating shaft 303 and the active roller 305 on its surface to rotate. The rotation of the active roller 305 drives the active wheel 308 to rotate synchronously. The active wheel 308 drives the driven wheel 309 and the second rotating shaft 304 to rotate synchronously through the belt 310. The rotation of the second rotating shaft 304 drives the driven roller 306 to follow the active roller 305 to move synchronously. The active roller 305 and the driven roller 306 move synchronously. The step motion drives the metal plate A to move backward, and the pressure roller 311 is adjusted by the pressure of the spring 316 to ensure that the metal plate A is in close contact with the active roller 305 and the driven roller 306 to provide stable transmission. When the thickness of the metal plate A increases, the metal plate A pushes the pressure roller 311 to move upward, and pulls the V-block 405a-1 upward through the connecting rod 407. When the V-block 405a-1 moves upward, it drives the first piston plate 406 to disengage from the water spray hole 401a, and pulls the first connecting rod 410a to lift upward, so that the first piston plate, the first piston plate 406 and other piston plates move upward, and the water spray hole 401a at the center is opened. At this time, the water pump 412 is started, and the water pump 412 pumps the cold water stored in the water tank 411 along the water suction pipe 414 and the water outlet pipe. 413 is transported to the interior of the fixed pipe 408, and the cold water in the fixed pipe 408 is injected into the water spray box 401 along the first connecting pipe 409a. The cold water entering the water spray box 401 can be sprayed onto the surface of the metal plate A along the opened water spray hole 401a to cool it down. When the V-shaped block 405a-1 continues to push the mounting plate 405 to rise along the interior of the water spray box 401, it will drive the first connecting block 405a to rise upward. When the first connecting block 405a is lifted upward, it will drive the second piston plate 405a-2 to disengage from the corresponding water spray hole 401a. At this time, more water spray holes 401a will be opened. When the first connecting block 405a is lifted upward, the first connecting rod 410a is pulled upward by the L-shaped connecting rod 410e.The first connecting rod 410a is lifted upward to drive the first sealing plug 409b-1 to disengage from the second connecting pipe 409b. At this time, the first connecting pipe 409a and the second connecting pipe 409b are both in an open state. The cold water in the fixed pipe 408 can be injected into the spray box 401 along the first connecting pipe 409a and the second connecting pipe 409b at the same time. The cold water injected into the spray box 401 can be sprayed onto the surface of the metal plate A from the opened spray hole 401a. When the V-shaped block 405a-1 continues to be lifted upward, the third connecting block 405c is pulled upward through the mounting plate 405. When the third connecting block 405c is lifted upward, the second connecting rod 410b is pulled upward through the L-shaped connecting rod 410e. When the second connecting rod 410b is lifted upward, the second sealing plug 409 c-1 is separated from the inside of the third connecting pipe 409c. At this time, the first connecting pipe 409a, the second connecting pipe 409b and the third connecting pipe 409c are all in an open state. The cold water in the fixed pipe 408 can be injected into the spray box 401 along the first connecting pipe 409a, the second connecting pipe 409b and the third connecting pipe 409c at the same time. The cold water injected into the spray box 401 can be sprayed onto the surface of the metal plate A from the opened spray hole 401a. Similarly, as the thickness of the metal plate A gradually increases, the first connecting rod 410a will open accordingly to spray cold water on the surface of the metal plates A of different thicknesses. In this way, the equipment can realize the stable transmission of A and the function of automatically adjusting the cooling water spraying amount according to the thickness of the plate, thereby improving the automation level and cooling efficiency of the equipment.
