Description

Technical Field

[0001] This utility model relates to the technical field of copper tube casting milling device, and in particular to a copper tube casting milling device that facilitates the recycling of milling waste. Background Technology

[0002] In the production of high-precision copper tubes, due to varying diameter requirements, pre-formed tube blanks need to be drawn and expanded to obtain copper tubes of different diameters. After the copper tubes are drawn, their surfaces are milled using a copper tube casting milling device to remove oxide scale, ensuring the precision and thermal conductivity of the copper tubes.

[0003] For example, a milling machine for casting large-diameter copper tubes, patent number 202011364138.1, includes a base and two milling mechanisms arranged side-by-side on the base. The milling cutter of the first milling mechanism is located at the upper end, and the milling cutter of the second milling mechanism is located at the lower end. When the copper tube casting passes through the first milling mechanism, the upper surface of the casting is milled; when the copper tube casting passes through the second milling mechanism, the lower surface is milled. During the milling process, the milling waste generated is collected in a waste bin placed below the first and second milling mechanisms. However, with this collection method, the milling waste easily falls outside the waste bin, and when changing the waste bin, the machine needs to be stopped beforehand to avoid being caught in the milling cutter's milling surface, which is inconvenient.

[0019] The guide hopper 15 has a hopper cavity 151 formed in its upper part and a conveying straight pipe 152 located between the two collection boxes 14 in its lower part, which connects the hopper cavity 151 and the lifting conveyor 20. The inner walls on both sides of the hopper cavity 151 are inclined surfaces that slope downward from the opening 144 to the conveying straight pipe 152, so that the milling waste material falls into the conveying straight pipe 152 along the inner walls on both sides of the hopper cavity 151 and is output from the conveying straight pipe 152 to the lifting conveyor 20.

[0020] The lifting conveyor 20 includes a frame 21 and a lifting conveying structure 22 mounted on the frame 21. The lifting conveying structure 22 has a gentle conveying section 221 at one end adjacent to the milling machine 10 and a steep conveying section 222 at the other end away from the milling machine 10. The gentle conveying section 221 is located below the straight conveying pipe 152, and the steep conveying section 222 extends upward at a slope, with its bottom end connected to the gentle conveying section 221, for conveying milling waste upward along the slope.

[0021] Furthermore, in this embodiment, the base 11 is provided with a straightening mechanism 16 on the outside of the two collection boxes 14 and between the two collection boxes 14, for conveying copper tube castings and straightening copper tube castings.

[0022] Furthermore, in this embodiment, the base 11 is provided with a blowing structure 17 located above the straightening mechanism 16 between the two collection boxes 14; each collection box 14 is provided with a sliding groove 102 on its outer edge facing the other collection box 14, and a lifting baffle 103 is detachably installed between the two sliding grooves 102; the guide hopper 15 is provided with a discharge port 153 on its upper part that is vertically opposite to the blowing structure 17 and communicates with the hopper cavity 151, so that the blowing structure 17 blows air onto the copper tube casting billet to blow off the residual milling waste.

The method includes the following steps: First, when the copper tube billet passes through the through-hole 143 relative to the collection box 14, the first milling mechanism 12 mills the upper surface of the billet, and the second milling mechanism 13 mills the lower surface of the billet. Milling waste falls from the two through-holes 144 of the collection box 14 into the guide hopper 15. Then, as the billet passes between the two collection boxes 14, the blowing structure 17 blows air onto the copper tube billet, blowing off the remaining milling waste. The milling waste falls into the guide hopper 15 under the obstruction of the lifting baffle 103. In the second step, the milling waste falls along the inner walls of both sides of the hopper cavity 151 into the conveying straight pipe 152, and is then output from the conveying straight pipe 152 to the lifting conveyor 20. In the third step, the milling waste falls into the gentle conveying section 221, and is then conveyed from the gentle conveying section 221 to the steep extension conveying section 222, being conveyed upwards along the slope of the steep extension conveying section 222 until it is output from the output end of the steep extension conveying section 222. In the fourth step, the waste collection vehicle 30 is positioned below the output end of the steep extension conveying section 222 to receive the milling waste output from the steep extension conveying section 222. In this way, while accurately collecting the milling waste, the waste collection vehicle 30 can be safely and conveniently replaced.

[0026] In summary, the copper tube billet milling device of this utility model, which facilitates the recycling of milling waste, can accurately collect milling waste through the cooperation between the milling host 10, the lifting conveyor 20 and the waste recycling cart 30, and can replace the waste recycling cart 30 more safely and conveniently.
