[0002] In the current mechanical processing process, the processing of metal plates is widely used. When processing metal plates, multiple operations such as cutting and punching are often performed on the metal plates. Among them, punching and perforating is to use stamping equipment to cut and shape the metal plates to produce metal products of various shapes and sizes.

[0003] Existing metal machines often require manual placement of metal plates before processing, followed by punching and punching, and finally manual removal before the next metal plate can be processed. Once this method involves batch processing, it will seriously slow down the overall processing speed, resulting in reduced production efficiency. Utility Model Content

[0004] The purpose of the present utility model is to solve the following shortcomings in the prior art: the existing metal machines often require manual placement of the metal plate before processing, and then the machine performs punching and punching, and finally manually removes it before continuing to process the next metal plate. Once this method involves batch processing, it will seriously slow down the overall processing speed, thereby reducing production efficiency. A quick-release structure for a battery box is proposed.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A metal machining punching device comprises a body, wherein the left and right side walls of the body are fixedly mounted with support blocks, a plurality of the support blocks are fixedly mounted with a top cover through a plurality of support rods, the top cover is connected to a lifting block through a hydraulic component, a rack rod is provided on the side wall of the lifting block, a punching head is fixedly mounted on the lower surface of the lifting block, a transmission shaft is rotatably mounted on the lower surface of the top cover through a fixed block, one end of the transmission shaft is connected to a ratchet component, and the other end is fixedly sleeved with a driving sprocket, the ratchet component comprises a ratchet fixedly sleeved on the transmission shaft The wheel disc has a ratchet gear rotatably sleeved on the ratchet disc, the outer ring of the ratchet gear is provided with external teeth, the inner ring is provided with a tooth opening, and its outer teeth are meshed with the rack rod, a plurality of slots are provided on the ratchet disc, and a torsion spring shaft is rotatably installed on the side wall of the slot, and a pawl is fixedly sleeved on the torsion spring shaft, two rollers are horizontally rotatably installed on the inner wall of the machine body, one end of one of the rollers passes through the side wall of the machine body and is fixedly sleeved with a driven sprocket, a chain is meshed and wrapped around the driving sprocket and the driven sprocket, and a transmission belt is wrapped around the surface of the two rollers.

[0007] Preferably, a template belt is fixedly sleeved on the surface of the conveying crawler belt, and a plurality of template grooves matching the size of the metal plate are opened on the surface of the template belt.

[0008] Preferably, the hydraulic component includes a hydraulic cylinder fixedly mounted on the upper surface of the top cover, a drive shaft of the hydraulic cylinder passes through the top cover and is fixedly connected to the lifting block.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] The terms "upper", "lower", "left", "right", "middle" and "one" used in the present invention are only for the convenience of description and are not intended to limit the scope of application of the present invention. Changes or adjustments to their relative relationships shall be deemed to be within the scope of application of the present invention without substantially changing the technical content.

[0021] Reference Figures 1-4 A metal machining punching device includes a body 1, support blocks 2 are fixedly installed on the left and right side walls of the body 1, multiple support blocks 2 are fixedly installed with a top cover 3 through multiple support rods, and the top cover 3 is connected to the lifting block 4 through a hydraulic component. The hydraulic component includes a hydraulic cylinder 18 fixedly installed on the upper surface of the top cover 3, the lower surface of the drive shaft of the hydraulic cylinder 18 passes through the top cover 3 and is fixedly connected to the upper surface of the lifting block 4, a rack rod 5 is opened on the side wall of the lifting block 4, a punching head is fixedly installed on the lower surface of the lifting block 4, and a transmission shaft 10 is rotatably installed on the lower surface of the top cover 3 through a fixed block 19. One end of the transmission shaft 10 is connected to a ratchet component, and the other end is fixedly sleeved with The driving sprocket 11 and the ratchet component include a ratchet plate 7 fixedly sleeved on the transmission shaft 10, and the ratchet plate 7 is rotatably sleeved with a ratchet gear 6. The outer ring of the ratchet gear 6 is provided with external teeth, and the inner ring is provided with a tooth opening, and its outer teeth are meshed with the rack rod 5. A plurality of slots are provided on the ratchet plate 7, and a torsion spring shaft 9 is rotatably installed on the side wall of the slot, and a pawl 8 is fixedly sleeved on the torsion spring shaft 9. Two rollers 14 are horizontally rotatably installed on the inner wall of the body 1, one end of which passes through the side wall of the body 1 and is fixedly sleeved with a driven sprocket 13. A chain 12 is meshed and wound around the driving sprocket 11 and the driven sprocket 13, and a conveyor belt 15 is wrapped around the surface of the two rollers 14.

[0022] During processing, the hydraulic cylinder 18 will push the lifting block 4 to move vertically downward through the driving shaft, and then punch the metal plate on the conveyor belt 15 through the punching head. At the same time, the rack rod 5 will drive the ratchet gear 6 to start rotating counterclockwise, but because the teeth of its inner ring will press the pawl 8 into the slot, the ratchet disk 7 will not rotate. When the punching of the metal plate is completed, the lifting block 4 will start to move up and reset. At this time, the rack rod 5 will drive the ratchet gear 6 to start rotating clockwise. At this time, the teeth of its inner ring will press against the pawl 8, thereby driving the entire ratchet disk 7 to start rotating, and then drive the roller 14 to start rotating through the active sprocket 11, chain 12 and driven sprocket 13, so that the conveyor belt 15 starts to move, transporting the processed metal plate away, and transporting the next metal plate to be processed to the bottom of the punching head.

[0023] A template belt 16 is fixedly sleeved on the surface of the conveying crawler 15 , and a plurality of template grooves 17 matching the size of the metal plate are opened on the surface of the template belt 16 .

[0024] The template belt 16 rotates along with the conveyor belt 15 , and the template grooves 17 provided on the surface of the template belt 16 can be used to place and fix the metal plates.

[0026] The metal plates to be processed are placed in batches into the placement box 21, and the bottom metal plate will fall from the placement entrance into one of the template slots 17. The remaining metal plates will continue to accumulate in the placement box 21 due to the height limit below the placement entrance. When the conveyor belt 15 moves, the bottom metal plate will be sent under the punching head, and the next metal plate will just fall into the next corresponding template slot 17. This alternating cycle will continue, and the metal plate after punching will continue to move with the conveyor belt 15, and then pass through the cleaning plate. At this time, the magnetic head 20 will absorb the metal waste remaining on the surface of the metal plate, and finally the clean metal plate will fall into the collection box 22.

[0027] The longitudinal section of the magnet head 20 is circular, and the radius covers the entire template groove 17 .

[0028] The magnet head 20 fully covers and absorbs the metal scraps on the template groove 17 .

[0029] After the punching is completed, the lifting block 4 will start to move up and reset, and the rack rod 5 will drive the ratchet gear 6 to start rotating clockwise. At this time, the teeth of its inner ring will press the ratchet 8 into the slot, thereby driving the entire ratchet disc 7 to start rotating, and then the driving sprocket 11, chain 12 and driven sprocket 13 will drive the roller 14 to start rotating, so that the conveyor belt 15 starts to move, and the processed metal plate is transported away, and the next metal plate to be processed is transported to the bottom of the punching head, thereby realizing fully automatic punching and transportation of metal plates, reducing labor costs and punching errors, and improving overall production efficiency.

[0030] In the present invention, unless otherwise clearly specified or limited, the terms “installed”, “connected”, “connected”, “fixed” and the like should be understood in a broad sense.
