In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0027] Example 1 Reference Figure 1~Figure 2 , which is the first embodiment of the present invention, provides a circular steel plate stamping device for steel processing, including a lower die 100, a top plate 200 is fixedly arranged on the top of the lower die 100, a pneumatic push rod 300 is fixedly arranged on the bottom side of the top plate 200, a punching head 400 is fixedly arranged on the output end of the pneumatic push rod 300, and, The rotary cutting assembly 500 is used to cut a certain depth on the surface of the steel plate, and includes a mounting member 501 disposed on the side of the punching head 400, a lifting member 502 disposed on the top of the mounting member 501, and a driving member 503 disposed on one side of the mounting member 501; The fixing assembly 600 is used to fix the steel plate, and includes a moving part 601 arranged on the surface of the processed steel plate and a power part 602 arranged on the side of the pneumatic push rod 300.

[0028] When in use, the steel plate is first placed on the surface of the lower die 100, and then the fixing assembly 600 is used to preliminarily fix the steel plate, and then the rotary cutting assembly 500 is used to cut the surface of the steel plate, and finally the pneumatic push rod 300 pushes the punching head 400 to punch the steel plate.

[0029] Example 2 Reference Figure 3~Figure 5, which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the mounting member 501 includes an inner ring 501a, a rotating frame 501b and a cutting knife 501c, the inner ring 501a is arranged on the outside of the punching head 400, the rotating frame 501b is rotatably arranged on the side of the inner ring 501a, and the cutting knife 501c is fixedly arranged at the bottom of the rotating frame 501b.

[0030] The side of the rotating frame 501b is provided with teeth, and a pair of cutting knives 501c are set symmetrically on both sides of the punching head 400. The inner diameter of the rotating frame 501b is equal to the diameter of the punching head 400. The purpose is to cut a cutting groove with the same diameter as the processed circular steel plate.

[0031] The lifting member 502 includes a rack 1 502a, a lifting plate 502b, a rack 2 502c, a transmission gear 502d, a slide 1 502e, a fixing frame 1 502f, a slide 2 502g and a fixing frame 2 502h. The rack 1 502a is fixedly arranged on the top of the inner ring 501a, the lifting plate 502b is sleeved and fixedly arranged on the output end of the pneumatic push rod 300, the rack 2 502c is fixedly arranged on the side of the lifting plate 502b, and the transmission gear 502d is rotatably arranged on the side of the fixed end of the pneumatic push rod 300. The transmission gear 502d is located between the rack 1 502a and the rack 2 502c and is respectively meshed with the rack 1 502a and the rack 2 502c.

[0032] Slide groove 1 502e is opened on the side of rack 1 502a, fixed frame 1 502f is fixedly set on the side of the fixed end of the pneumatic push rod 300, rack 1 502a is slidably set on the side of fixed frame 1 502f through slide groove 1 502e, slide groove 2 502g is opened on the side of rack 2 502c, fixed frame 2 502h is fixedly set on the side of the fixed end of the pneumatic push rod 300, and rack 2 502c is slidably set on the side of fixed frame 2 502h through fixed frame 2 502h.

[0033] Among them, the slide groove 1 502e, the fixed frame 1 502f, the slide groove 2 502g and the fixed frame 2 502h cooperate with each other to slide, the purpose of which is to form a supporting effect for the rack 1 502a and the rack 2 502c to prevent the two from bending during use.

[0034] The driving member 503 includes a connecting plate 503a, a mounting frame 503b, a motor 503c and a driving gear 503d. The connecting plate 503a is fixedly arranged on the top of the rack 502a, the mounting frame 503b is fixedly arranged on the bottom of the connecting plate 503a, the motor 503c is fixedly arranged on the inner side of the mounting frame 503b, and the driving gear 503d is fixedly arranged on the output end of the motor 503c, and the driving gear 503d is meshed with the teeth on the side of the rotating frame 501b.

[0035] The function of the rotary cutting assembly 500 is to cut a cutting groove with the same diameter as the circular steel plate to be processed on the steel plate before punching, and to retract the cutting knife 501c during punching.

[0036] In specific use, after placing the unprocessed steel plate, the motor 503c is started and drives the driving gear 503d to rotate. After the driving gear 503d rotates, it drives the rotating frame 501b to rotate. During the rotation process, the blade of the cutting knife 501c forms a circular cut mark on the surface of the steel plate. When punching the steel plate, the punched and unpunched parts of the steel plate surface will separate and deform under the action of shear force. This process will inevitably produce burrs on the edge of the blanking part. The existence of the cut mark reduces the deformation of the punched and unpunched parts of the steel plate, making separation easier, reducing burrs, and increasing the bright surface, thereby improving the quality of the circular steel plate.

[0037] After the cutting is completed, the steel plate needs to be punched. At this time, the pneumatic push rod 300 controls the punching head 400 to impact downward. During the impact process, the lifting member 502 drives the cutting knife 501c to move upward. First, the output end of the pneumatic push rod 300 moves downward, and the lifting plate 502b of the output end portion moves downward synchronously and drives the rack 1 502a to move downward. At the same time, the rack 1 502a drives the transmission gear 502d to rotate. After the transmission gear 502d rotates, it drives the rack 2 502c to move upward. After the rack 2 502c moves upward, it drives the inner ring 501a and the connecting plate 503a to move upward respectively, and then drives the driving gear 503d and the rotating frame 501b to move upward synchronously, so that it can ensure that the driving gear 503d and the side of the rotating frame 501b are always in meshing. It is worth noting that three groups of racks 1 502a and 2 502c are provided, and their purpose is to allow the inner ring 501a to drive the rotating frame 501b to rise and fall smoothly, so as to prevent the punching head 400 from touching the blade of the cutting knife 501c when moving downward; and the pneumatic push rod 300 applies pressure to the cutting knife 501c by means of the transmission between the racks 1 502a and 2 502c, so as to ensure that the cutting knife 501c has enough pressure to cut the steel plate to a certain depth.

[0038] The reason why the cutting knife 501c needs to be lifted is to protect the cutting knife 501c. If the cutting knife 501c does not move, the punching head 400 will move down and squeeze the steel plate, which will squeeze the cutting knife 501c inside the cut mark, thereby causing the blade to deform. Lifting the cutting knife 501c can avoid this problem.

[0039] The remaining structures are the same as those of Example 1.

[0040] Example 3 Reference Figure 3~Figure 6, which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: the moving member 601 includes a guide block 601a, a semicircular clamping block 601b and a semicircular clamping hole 601c. The guide block 601a is placed on the surface of the steel plate in an arc shape. The guide blocks 601a are provided with three blocks. The three guide blocks 601a are evenly surrounded by the outer side of the cutting knife 501c. The semicircular clamping block 601b is fixedly arranged on the side of the guide block 601a. ​​The semicircular clamping hole 601c is provided on the side of the guide block 601a away from the semicircular clamping block 601b. The semicircular clamping blocks 601b and the semicircular clamping holes 601c of different guide blocks 601a can be clamped. After the three guide blocks 601a are spliced, they form a circular ring with the same diameter as the circular steel plate.

[0041] The power part 602 includes a telescopic rod 602a, a strip plate 602b, a spring 602c, a transmission frame 602d and a connecting rod 602e. There are multiple telescopic rods 602a, and the multiple telescopic rods 602a are rotatably arranged on the sides of different guide blocks 601a in pairs. The strip plate 602b is fixedly arranged on the side of the telescopic rod 602a away from the guide block 601a. ​​The telescopic rod 602a is rotatably arranged on the surface of the lower mold 100 through the strip plate 602b.

[0042] The spring 602c surrounds the output end of the pneumatic push rod 300 and is fixedly set on the top of the lifting plate 502b, the transmission frame 602d surrounds the outside of the pneumatic push rod 300 and is fixedly set on the end of the spring 602c away from the lifting plate 502b, the connecting rod 602e is rotatably set on the middle part of the side of the guide block 601a, and the end of the connecting rod 602e away from the guide block 601a is rotatably set on the end of the transmission frame 602d away from the pneumatic push rod 300.

[0043] The fixing assembly 600 is mainly used for fixing the steel plate, and the fixing is divided into two stages. One is when the cutting knife 501c cuts the steel plate, and the steel plate only needs to remain stationary. The other is when the punching head 400 punches the steel plate, and it is necessary not only to ensure that the steel plate remains stationary, but also to ensure that the inner wall of the guide block 601a and the punching head 400 are in contact.

[0044] In the first stage, the three guide blocks 601a are in a separated state, but since the spring 602c exerts a pulling force on the transmission frame 602d, and the transmission frame 602d transmits the pulling force to the guide block 601a through the connecting rod 602e, the guide block 601a has a fixing effect on the steel plate under the action of the spring 602c. After being fixed, the steel plate will not move when being cut by the cutting knife 501c, so that the cutting knife 501c can cut out a full circle.

[0045] In the second stage, the pneumatic push rod 300 is started, and its output end moves downward, and the lifting plate 502b pulls the transmission frame 602d through the spring 602c, and the transmission frame 602d squeezes the connecting rod 602e, so that the connecting rod 602e drives the guide block 601a to slide on the surface of the steel plate, wherein the telescopic rod 602a guides the movement of the guide block 601a to prevent the guide block 601a from deflecting when moving. The three guide blocks 601a are simultaneously approached to the punching head 400 under the push of the connecting rod 602e, and finally merged, at which time the semicircular clamping block 601b on the side of the guide block 601a is clamped with the semicircular clamping hole 601c, making the connection of each guide block 601a more stable.

[0046] The merged guide block 601a forms a circular ring that can just allow the punching head 400 to pass through. With the circular ring formed by the guide block 601a on the upper surface of the steel plate and the lower die 100 on the lower surface fixed together, when the punching head 400 impacts the steel plate, shaking and deviation are reduced, thereby improving the punching accuracy and the stability of the punching process.

[0047] The remaining structure is the same as that of Example 2.
