The working principle is as follows:

(1) the red high-temperature copper rod 44 is inserted into the feed hole 103 from the back front edge of the bottom surface of the bracket 20 until the end part of the red high-temperature copper rod abuts against the positioning block 30; the telescopic ends of the first air cylinders 3 are driven to extend outwards, so that the two ejector rods 7 are driven to be drawn close to each other transversely until the end parts of the two ejector rods 7 respectively press the left side and the right side of the high-temperature copper bar 44, and in the process, the two T-shaped sliding blocks 5 are kept still; then, the flexible end of drive second cylinder 16 stretches out outwards, and then drives with the help of traction block 15 and pull strip 13 and vertically shift up in guide block 12, thereby drive trapezoidal piece 14 and move up, and then order about the equal outwards swing in upper end of two arc pendulum rods 6, thereby drive two T type sliders 5 with the help of two bolts 9 and all inwards move in order to be close to each other, and then drive two equal inwards movement of blade 8, thereby cut off high temperature bar copper 44 with the help of establishing the cutting edge in two blade 8 inboards in order to form towards the material, stopper 17 has guaranteed the straightness that hangs down of the flexible end concertina movement of second cylinder 16.

(2) The punched material formed after cutting slides forwards to fall into one receiving groove 41 on the left side, then the telescopic end of one fourth air cylinder 33 on the right side is driven to extend outwards, and then the carrier block 42 is driven to move leftwards along the two guide columns 32, so that the middle receiving groove 41 is moved to the position below the feeding hole 103, and then the step (1) is repeated, so that the next punched material slides into the middle receiving groove 41.

(3) The telescopic end of a fifth cylinder 40 on the left side is driven to contract inwards, so that the first baffle 39 is driven to slide downwards, and at the moment, the punching materials in the material receiving groove 41 on the left side and the middle part respectively slide downwards into the punching equipment due to lack of blocking; when two punching materials leave two receiving grooves 41, the telescopic end of the fourth cylinder 33 on the right side is driven to contract inwards, and then the receiving groove 41 on the left side is driven to move to the position below the feeding hole 103, so that a cycle is formed.

(4) If the last section material length of high temperature bar copper 44 does not accord with the processing requirement, then the flexible end of a fourth cylinder 33 on drive right side stretches out outwards, support the dog 34 until the left side of carrier block 42, at this moment, one on right side connects silo 41 to move to the below of feed port 103, the last section material of high temperature bar copper 44 will slide down and connect in silo 41 on right side, the flexible end of a fourth cylinder 33 on drive right side is inwards shrunk, and then drive second baffle 38 and move down, one that is located right side connects in the silo 41 loses and blocks the back outwards output in order to retrieve.

(5) The hand wheel 29 is rotated to drive the screw 27 to rotate in the internal thread sleeve 26, and then the slide block 25 is driven to slide back and forth along the guide rod 23 according to the principle of threaded connection, so that the back and forth positions of the third cylinder 28 and the positioning block 30 are adjusted by the aid of the end block 24; in addition, the cutting length of the punching material can be adjusted by driving the telescopic end of the third cylinder 28 to move telescopically and adjusting the front and back positions of the positioning block 30.

(6) The two blades 8 directly contact the high-temperature copper bar 44, so that the temperature is easily heated and also begins to rise, the temperature on the two blades 8 is further transmitted to the back block 1 by virtue of the two T-shaped sliders 5, at the moment, cooling liquid can enter the two through holes 105 through the lower-end openings of the two through holes 105, and finally flows out from the upper-end openings of the two through holes 105 in an outward circulating mode, so that the temperature of the back block 1 is reduced; meanwhile, the cooling liquid enters the two Z-shaped sunk grooves 104 through the two second counter bores 106 and finally circulates outwards through the two first counter bores 107, so that the temperature of the two T-shaped sliders 5 is reduced by the two Z-shaped sunk grooves 104.

(7) Lubricating oil can enter between the lower side inner walls of the T-shaped sliding blocks 5 and the sliding grooves 101 through the two oil inlet holes 108, so that the two T-shaped sliding blocks 5 can slide smoothly, redundant lubricating oil flows towards the middle, and residues falling off during cutting are taken away and are discharged outwards through the return holes 109.

The utility model can clamp and fix the copper bar before cutting, thereby preventing the high temperature copper bar from skewing when cutting off, ensuring the punching cut to be smooth and vertical, further ensuring the punching weight to be uniform and stable, thereby reducing the defective rate of finished products; in addition, the temperature of the back block 1 and the two T-shaped sliders 5 can be effectively reduced after the cooling liquid flows through the two Z-shaped counter bores 104, the two first counter bores 107, the two second counter bores 106 and the two through holes 105 on the back block 1, so that the heat dissipation function is achieved, the heat of high-temperature punching materials is prevented from being transmitted to executing elements such as cylinders, and the service lives of the executing elements such as the cylinders are prolonged.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those skilled in the art that various changes in the embodiments and modifications thereof may be made, and equivalents may be substituted for elements thereof; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
