Description

Technical Field

[0001] The invention relates to a material cutting device for valve hot punching equipment. Background Art

[0027] Working principle:

[0028] (1) The red-hot high-temperature copper rod 44 is inserted into the feed hole 103 from the bottom surface of the rear-to-front bracket 20 until its end abuts against the positioning block 30; the telescopic ends of the first cylinder 3 are driven to extend outward, thereby driving the two push rods 7 to move horizontally closer to each other until the ends of the two push rods 7 respectively press the left and right sides of the high-temperature copper rod 44. During this process, the two T-shaped sliders 5 remain stationary; then, the telescopic end of the second cylinder 16 is driven to extend outward, thereby driving the traction bar 13 to move vertically upward in the guide block 12 with the help of the traction block 15, thereby driving the trapezoidal block 14 to move upward, and then driving the upper ends of the two arc-shaped swing rods 6 to swing outward, thereby driving the two T-shaped sliders 5 to move inward with the help of the two bolts 9 to move closer to each other, and then driving the two blades 8 to move inward, thereby cutting the high-temperature copper rod 44 with the help of the blades arranged on the inner sides of the two blades 8 to form a punch, and the limit block 17 ensures the verticality of the telescopic movement of the telescopic end of the second cylinder 16.

[0029] (2) The punched material formed after cutting slides forward into a receiving trough 41 on the left, and then drives the telescopic end of a fourth cylinder 33 on the right to extend outward, thereby driving the carrier block 42 to move leftward along the two guide pillars 32, thereby moving the middle receiving trough 41 to the bottom of the feed hole 103, and then repeating step (1) to allow the next punched material to slide into the middle receiving trough 41.

[0030] (3) The telescopic end of a fifth cylinder 40 on the left is driven to retract inward, thereby driving the first baffle 39 to slide down. At this time, the punching materials in the receiving troughs 41 on the left and the middle respectively slide down into the stamping equipment due to the lack of obstruction; when the two punching materials leave the two receiving troughs 41, the telescopic end of a fourth cylinder 33 on the right is driven to retract inward, thereby driving a receiving trough 41 on the left to move to the bottom of the feed hole 103, thereby forming a cycle.

[0031] (4) If the length of the last section of the high-temperature copper rod 44 does not meet the processing requirements, the telescopic end of the fourth cylinder 33 on the right is driven to extend outward until the left side of the carrier block 42 abuts against the stopper 34. At this time, a material receiving trough 41 on the right moves to the bottom of the feed hole 103, and the last section of the high-temperature copper rod 44 will slide into the material receiving trough 41 on the right, driving the telescopic end of the fourth cylinder 33 on the right to shrink inward, thereby driving the second baffle 38 to move downward. The material in the material receiving trough 41 on the right loses its obstruction and is output outward for recycling.

[0032] (5) The hand wheel 29 is turned to drive the screw rod 27 to rotate in the internal threaded sleeve 26, and then the slider 25 is driven to slide forward and backward along the guide rod 23 according to the principle of threaded connection, so that the front and rear positions of the third cylinder 28 and the positioning block 30 are adjusted with the help of the end block 24; in addition, the telescopic end of the third cylinder 28 is driven to telescope, which can also adjust the front and rear position of the positioning block 30, thereby adjusting the cutting length of the punching material.

[0033] (6) Since the two blades 8 are in direct contact with the high-temperature copper rod 44, they are easily heated and begin to heat up. The temperature of the two blades 8 is then transferred to the back block 1 with the help of the two T-shaped sliders 5. At this time, the coolant can enter the two through holes 105 through the lower end openings of the two through holes 105, and finally circulate outward from the upper end openings of the two through holes 105, thereby reducing the temperature of the back block 1; at the same time, the coolant enters the two Z-shaped sink grooves 104 through the two second sink holes 106, and finally circulates outward through the two first sink holes 107, thereby reducing the temperature of the two T-shaped sliders 5 with the help of the two Z-shaped sink grooves 104.

[0034] (7) The lubricating oil can enter between the T-shaped slider 5 and the lower inner wall of the slide groove 101 through the two oil inlet holes 108, so that the two T-shaped sliders 5 can slide smoothly, and the excess lubricating oil flows to the middle, thereby taking away the residue dropped during cutting and being discharged outward through the reflux hole 109.

[0035] The present invention can clamp and fix the copper rod before cutting, thereby preventing the high-temperature copper rod from tilting during cutting, ensuring that the cut of the punching material is flat and vertical, and further ensuring that the weight of the punching material is uniform and stable, thereby reducing the defective rate of finished products; in addition, after the coolant flows through the two Z-shaped sink grooves 104, the two first sink holes 107, the two second sink holes 106 and the two through holes 105 on the back block 1, the temperature of the back block 1 and the two T-shaped sliders 5 can be effectively reduced, thereby having a heat dissipation function, thereby preventing the heat of the high-temperature punching material from being transferred to actuators such as cylinders, thereby extending the service life of actuators such as cylinders.
