DETAILED DESCRIPTION

[0023] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] like Figure 1-Figure 7 A metal cutting device for mechanical processing shown in FIG. 1 includes a workbench 1, both sides of which are fixedly connected to a mounting base 101, a receiving groove 102 being provided on the surface of the workbench 1, a cutting mechanism 2 being provided inside the receiving groove 102, and an auxiliary mechanism 3 being provided on the top of the workbench 1; wherein, the cutting mechanism 2 includes a mounting shell 209 provided inside the receiving groove 102, a cutting disc 208 being provided inside the mounting shell 209, the cutting disc 208 passing through the mounting shell 209, a second motor 207 being provided on one side of the mounting shell 209, the output shaft of the second motor 207 being fixedly connected to a transmission mechanism 211, a connecting shaft 210 being fixedly connected on one side of the cutting disc 208, the other end of the connecting shaft 210 passing through the mounting shell 209 and fixedly connected to the other end of the transmission mechanism 211, and two hydraulic push rods 215 for adjusting the position of the auxiliary mechanism 3 being provided on the top of the mounting base 101.

[0026] Specifically, the transmission mechanism 211 is a relatively mature component in existing technical applications, and is composed of two transmission wheels and a transmission belt. By driving one of the transmission wheels to rotate, the other transmission wheel can be driven to rotate under the action of the transmission belt.

[0027] Starting the second motor 207 can drive the connecting shaft 210 to rotate through the transmission mechanism 211, thereby driving the cutting disc 208 to rotate.

[0028] like Figure 1-Figure 7 As shown, a first motor 201 is provided inside the workbench 1, and the output shaft of the first motor 201 is fixedly connected to a screw rod 202, the other end of the screw rod 202 is rotatably connected to the inner wall of the storage groove 102, and the surface of the screw rod 202 is threadedly connected to a connecting seat 203, both sides of the connecting seat 203 are slidingly connected to the inner wall of the storage groove 102, and a mounting block 204 is provided on the top of the connecting seat 203, and the top of the mounting block 204 is fixedly connected to the bottom of the mounting shell 209.

[0029] The bottom of the mounting block 204 is fixedly connected to a counterweight rod 205, the lower end of the counterweight rod 205 passes through the connecting seat 203 and is slidably connected to the inner wall of the connecting seat 203, and the inner wall of the storage groove 102 is provided with a mounting rod 206, both ends of the mounting rod 206 pass through the workbench 1 and are fixedly connected to a fixed block 214, and the mounting block 204 is slidably connected to the surface of the mounting rod 206.

[0030] Two liquid storage cylinders 216 are fixedly connected on both sides of the workbench 1, and the inner wall of one of the liquid storage cylinders 216 is slidably connected to a first adjusting rod 218, and the bottom of the first adjusting rod 218 and the inner wall of the liquid storage cylinder 216 are filled with hydraulic oil. The inner bottom wall of the other liquid storage cylinder 216 is slidably connected to a second adjusting rod 219, and the upper end of the second adjusting rod 219 passes through the liquid storage cylinder 216 and is fixedly connected to the surface of the fixed block 214. The upper end of the first adjusting rod 218 passes through the liquid storage cylinder 216 and is fixedly connected to the surface of the auxiliary mechanism 3. A conduit 217 is connected between the two adjacent liquid storage cylinders 216.

[0031] Two symmetrically distributed cavities 212 are defined inside the installation shell 209 , and evenly distributed exhaust holes 213 communicating with the cavities 212 are defined on the top of the installation shell 209 .

[0032] By starting the first motor 201, the screw rod 202 can be driven to rotate, and in the process, the connecting seat 203 is driven to slide along the inner wall of the storage groove 102, so that the mounting block 204 is driven by the counterweight rod 205 to move the mounting shell 209 synchronously, thereby achieving the effect of driving the cutting disc 208 to move. Under normal circumstances, the counterweight rod 205 can keep the cutting disc 208 inside the storage groove 102 under the action of gravity, and the auxiliary mechanism 3 is driven downward by the hydraulic push rod 215 to drive the first adjusting rod 218 to move downward, so that it can squeeze the liquid stored in the storage cylinder 2 16, is injected into another liquid storage cylinder 216 through the conduit 217 and lifts the second adjusting rod 219, so that the second adjusting rod 219 drives the fixing block 214 to move upward, thereby driving the mounting rod 206 through the fixing block 214 to move the mounting block 204 upward, thereby achieving the effect of extending the cutting disc 208 from the inside of the storage groove 102. When it is not fixed, the gravity of the counterweight rod 205 ensures that the cutting disc 208 will not extend from the inside of the storage groove 102 when the metal plate to be cut is not fixed, thereby improving the safety factor.

[0033] like Figure 1-Figure 7 As shown, the auxiliary mechanism 3 includes a connecting shell 301 arranged on the top of the workbench 1, and both sides of the connecting shell 301 are fixedly connected with mounting parts fixedly connected to the output shaft of the hydraulic push rod 215, and the inner side of the connecting shell 301 is fixedly connected with two symmetrically distributed mounting boxes, and ventilation slots 302 are provided on opposite sides of the two mounting boxes. A filter 303 is fixedly connected to the inner wall of the mounting box, and a fan 304 is provided inside the mounting box on the side of the filter 303 away from the ventilation slot 302.

[0034] An air duct 305 is connected to the surface of the installation box, and the other end of the air duct 305 is connected to the cavity 212 .

[0035] Both sides of the connecting shell 301 are fixedly connected with a fixing plate 306, the bottom of the fixing plate 306 is provided with a pressure plate 309, the top of the pressure plate 309 is fixedly connected with evenly distributed positioning rods 307, the upper end of the positioning rod 307 passes through the fixing plate 306, and the surface of the positioning rod 307 is provided with a spring 308.

[0036] The output shaft of the hydraulic push rod 215 contracts to drive the connecting shell 301 to move downward. During this process, the metal sheet placed on the workbench 1 can be squeezed and fixed by the joint action of the fixing plate 306, the pressure plate 309, the positioning rod 307 and the spring 308, thereby reducing shaking during the cutting process and improving the cutting effect. Moreover, the positioning rod 307 and the spring 308 cooperate with each other to enable the positioning rod 307 to pass through the fixing plate 306 and compress the spring 308 after the pressure plate 309 contacts the metal sheet and is blocked by the metal sheet. After being compressed, the spring 308 exerts a reaction force on the pressure plate 309 to improve the limiting effect on the metal sheet, while avoiding the situation where the metal sheet is damaged due to excessive squeezing.

[0037] Starting the fan 304 during the cutting process can guide the airflow through the ventilation slot 302 into the interior of the installation box, so that it can guide the debris generated during the cutting process into the interior of the installation box. During this process, the filter 303 can filter the debris, and the filtered airflow is introduced into the interior of the cavity 212 through the air guide tube 305 and discharged through the exhaust hole 213. This can speed up the air flow around the cutting disk 208 during the cutting process, reduce the impact of high temperature generated during the cutting process, effectively improve the service life of the equipment, and reduce the thermal damage to the metal plate caused by high temperature.

[0038] Working principle: The metal sheet to be cut is placed on the workbench 1 and is located below the connecting shell 301. The output shaft of the hydraulic push rod 215 is contracted to drive the connecting shell 301 to move downward. In this process, the metal sheet placed on the workbench 1 can be squeezed and fixed by the joint action of the fixing plate 306, the pressing plate 309, the positioning rod 307 and the spring 308, thereby reducing the shaking during the cutting process and improving the cutting effect. As the connecting shell 301 moves downward, the first adjusting rod 218 can be driven downward to squeeze the liquid stored in the liquid storage. The hydraulic oil inside the cylinder 216 is injected into another liquid storage cylinder 216 through the conduit 217 and lifts the second adjusting rod 219, so that the second adjusting rod 219 drives the fixed block 214 to move upward, thereby driving the mounting rod 206 through the fixed block 214 to move the mounting block 204 upward, thereby achieving the effect of extending the cutting disc 208 from the inside of the storage groove 102. When it is not fixed, the gravity of the counterweight rod 205 ensures that the cutting disc 208 will not extend from the inside of the storage groove 102 when the metal plate to be cut is not fixed, thereby improving the safety factor.
