For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0027] A punching device for metal processing, as shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , comprising a bottom plate 1, the top of the bottom plate 1 is fixedly connected with a moving mechanism 2, the top of the moving mechanism 2 is fixedly connected with a clamping mechanism 3, the top of the bottom plate 1 is fixedly connected with a punching plate 4, and the punching plate 4 is provided with a punching hole on one side, the top of the punching hole is fixedly connected with a concave die 5, one side of the punching plate 4 is fixedly connected with an eccentric mechanism 6, and the moving end of the eccentric mechanism 6 is fixedly connected with a punch 7.

[0028] Firstly, the metal plate to be punched is placed on the clamping mechanism 3, the clamping mechanism 3 is self-centered according to the support of the round bar and is fixed, then the moving mechanism 2 drives the clamping mechanism 3 and the metal bar to move to the concave die 5, then the eccentric mechanism 6 drives the punch 7 to punch the round bar according to the preset frequency, thereby preventing safety problems caused by employees pushing the metal bar by hand, and through the cooperation of the moving mechanism 2 and the eccentric mechanism 6, the consistency of the size and shape of each punched product is ensured, and the quality of the product is improved.

[0029] In order to push the clamping mechanism 3 and the metal bar, as Figure 3As shown, the moving mechanism 2 comprises a base 201, a slide rail 202, a sliding block 203, a lead screw 204, a bearing seat 205 and a motor 206, the base 201 is fixedly connected to the top of the bottom plate 1, the slide rail 202 is threadedly connected to the top of the base 201, the sliding block 203 is slidingly connected to the top of the base 201, the bearing seat 205 is fixedly connected to the top of the bottom plate 1, the lead screw 204 is fixedly connected to one end of the bearing seat 205, the motor 206 is fixedly connected to one side of the base 201, and the output end of the motor 206 is fixedly connected to one end of the lead screw 204, and the sliding block 203 is threadedly connected with the lead screw 204.

[0030] After the motor 206 is started, the motor 206 drives the lead screw 204 to rotate synchronously, and then the rotating movement of the lead screw 204 is converted into the linear movement of the sliding block 203 under the limitation of the slide rail 202 through the connection between the sliding block 203 and the lead screw 204, thereby driving the clamping mechanism 3 and the metal rod to make reciprocating linear movement along the slide rail 202, so that the consistency of the shape of each punched product is ensured each time, and the operator does not need to contact the metal rod with hands to push, thereby greatly reducing the accidents caused by the punch 7 and improving the safety of the equipment.

[0031] In order to clamp and fix the metal rod, as shown, Figure 4 As shown, the clamping mechanism 3 comprises a lower clamp jaw 301, a guide column 302, a spring 303, a baffle 304, a rotating rod 305, a symmetrical eccentric wheel 306, an upper clamp jaw 307 and a sliding groove frame 308, the sliding groove frame 308 is fixedly connected to the top of the sliding block 203, the lower clamp jaw 301 is slidingly connected to one side of the sliding groove frame 308, the upper clamp jaw 307 is slidingly connected to one side of the sliding groove frame 308, the guide column 302 is fixedly connected to the inside of the lower clamp jaw 301 and penetrates through the bottom of the upper clamp jaw 307, the baffle 304 is fixedly connected to the top of the guide column 302, the spring 303 is sleeved on the outer wall of the guide column 302, the symmetrical eccentric wheel 306 is rotationally connected to one side of the sliding groove frame 308 and is located between the baffle 304 and the upper clamp jaw 307, the rotating rod 305 is sleeved on the outer wall of the symmetrical eccentric wheel 306, and a hole is formed in one side of the sliding groove frame 308.

[0032] When it is necessary to fix the metal rod, the metal rod is placed between the upper jaw 307 and the lower jaw 301 through the hole. Rotating the rotating rod 305 causes the symmetrical eccentric wheel 306 to rotate. At this time, the baffle 304 is forced to move the guide post 302 upward. At the same time, the lower jaw 301 compresses the spring 303 as it moves with the guide post 302. Meanwhile, the symmetrical eccentric wheel 306 simultaneously compresses the upper jaw 307 downward. At this time, the upper jaw 307 and the lower jaw 301 gradually move towards the center as the symmetrical eccentric wheel 306 rotates. When the symmetrical eccentric wheel 306 is vertical compared to the initial state, it is locked. Thus, it can effectively prevent punching deviation caused by insecure clamping and can achieve automatic centering when fixing the metal rod, thereby improving the punching quality.

[0033] In order to stamp metal bars, such as Figure 5 As shown, the eccentric mechanism 6 includes a second motor 601, a disc 602, a connecting rod 603, a stamping rod 604, and a limiting sleeve 605. The second motor 601 is fixedly connected to one side of the stamping plate 4, and the output end of the second motor 601 passes through one side of the stamping plate 4. The disc 602 is fixedly connected to the output end of the second motor 601. The connecting rod 603 is fixedly connected to one side of the disc 602. The stamping rod 604 is rotatably connected to one side of the connecting rod 603. The limiting sleeve 605 is fixedly connected to one side of the stamping plate 4 and is sleeved on the outer wall of the stamping rod 604. The punch 7 is fixedly connected to the bottom of the stamping rod 604.

[0034] When the metal rod moves to the cutting position, motor 601 is started. Motor 601 drives the disc 602 to rotate synchronously. As the disc 602 rotates, the connecting rod 603 makes a circular motion. At the same time, the circular motion of the connecting rod 603 is converted into the up-and-down linear reciprocating motion of the stamping rod 604 under the restriction of the limiting sleeve 605. When the stamping rod 604 moves downward, the punch 7 also moves downward. At this time, the punch 7 is squeezed between the punch 7 and the die 5, and shear deformation occurs. Therefore, for metal rods with high hardness, the speed of motor 601 can be appropriately increased or the diameter of the disc 602 can be increased to increase the stamping force. Conversely, the stamping force can be reduced to avoid excessive stamping, which may cause material waste or quality problems, thereby improving the versatility and adaptability of the equipment.

[0035] Working principle: first, the metal plate to be punched is placed on the clamping mechanism 3, the clamping mechanism 3 is self-centered according to the support of the round bar and is fixed, then the moving mechanism 2 drives the clamping mechanism 3 and the metal bar to move to the die 5, then the eccentric mechanism 6 drives the punch 7 to punch the round bar according to the preset frequency, after starting the motor 206, the motor 206 drives the screw rod 204 to rotate synchronously, then the rotary motion of the screw rod 204 is converted into the linear motion of the sliding block 203 through the connection between the sliding block 203 and the screw rod 204 and under the limitation of the sliding rail 202, thereby driving the clamping mechanism 3 and the metal bar to do reciprocating linear motion along the sliding rail 202, when it is needed to fix the metal bar, the metal bar is placed between the upper clamping jaw 307 and the lower clamping jaw 301 through the hole, the rotating rod 305 is rotated to make the symmetrical eccentric wheel 306 rotate, at this time, the baffle 304 is forced to drive the guide column 302 to move upward, and the lower clamping jaw 301 is extruded by the guide column 302 when moving, at this time, the symmetrical eccentric wheel 306 extrudes the upper clamping jaw 307 downward, at this time, the upper clamping jaw 307 and the lower clamping jaw 301 gradually move to the center with the rotation of the symmetrical eccentric wheel 306, and when the symmetrical eccentric wheel 306 is in the vertical state compared with the initial state, it is locked, when the metal bar moves to the punching position, the motor 601 is started, the motor 601 drives the disc 602 to rotate synchronously, with the rotation of the disc 602, the connecting rod 603 does circular motion, and the circular motion of the connecting rod 603 is converted into the up-down linear reciprocating motion of the stamping rod 604 under the limitation of the limiting sleeve 605, when the stamping rod 604 moves downward, the punch 7 also moves downward, at this time, the punch 7 is extruded between the punch 7 and the die 5, and shear deformation occurs.
