Description

Technical Field

[0001] The invention relates to the technical field of copper alloy drawing, in particular to a copper alloy production and drawing processing equipment. Background Art

[0002] Copper alloy rod refers to an alloy rod composed of pure copper as the matrix and one or more other elements. It is widely used and can be cast and deformed as needed. Here we mainly focus on the drawing process in the deformation process.

[0003] During the drawing process, a small amount of debris is likely to be generated on the surface of the bar. If the debris is not cleaned up in time, it will be drawn with the bar in the next step, resulting in scratches on the surface of the bar. Lubricating oil is used in the drawing process, and some debris will drip down into the tank containing the lubricating oil, causing the lubricating oil in the tank to be contaminated. When the contaminated lubricating oil is used to lubricate the surface of the bar, the debris will attach to the surface of the bar again, affecting the drawing quality. When drawing copper alloys with different drawing ratios, a fixed number of drawing dies will cause ineffective wear of some drawing dies, resulting in waste and reducing the service life of some drawing dies.

[0016] 1. In the present invention, the oil dripping rack is matched with the chip removing rack, and the lubricating oil is used to bring a small amount of debris remaining on the surface of the copper alloy camphor material after the chip removing treatment into the oil tank 2, so as to prevent the debris from being retained on the surface of the copper alloy bar, and to avoid scratches caused by the scrapes when the copper alloy bar is drawn for the next time.

DETAILED DESCRIPTION

[0034] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0036] The copper alloy rods that have been straightened are conveyed to the right by the conveying rack 12. When the copper alloy rods enter the chip removal rack 28, the surface of the copper alloy rods is coated with lubricating oil by the chip removal rack 28. The copper alloy rods continue to move to the right and enter the drawing die 23 for preliminary drawing. The lubricating oil is introduced into the drawing die 23 through the oil conveying rack 24 to reduce the friction resistance. The copper alloy rods that have been initially drawn extend out of the drawing die 23 to the adjacent chip removal rack 28 for chip removal. The oil drip rack 27 cooperates with the lubricating oil to remove the copper alloy rods. A small amount of debris remaining on the surface of the copper alloy rod after the chip treatment is brought into the oil tank 25 to prevent the debris from being retained on the surface of the copper alloy rod. When the copper alloy rod is drawn for the next time, it is scratched by the debris. Then the copper alloy rod continues to enter the next drawing die 23 for drawing. When the copper alloy rod extends from the rightmost drawing die 23, the protruding part of the copper alloy rod is fixed with an external clamping tool and pulled to the right to speed up the drawing efficiency of the copper alloy rod. When the length of the copper alloy rod after the drawing treatment is After the demand is met, the copper alloy bar is cut by a cutting machine, removed and collected, and the copper alloy bar on the left continues to be drawn. When the copper alloy with increased copper content is drawn, the ductility of the copper alloy bar is improved, and the central drawing die 23 can be moved backward by the control frame 22 to reduce the drawing die 23 used in the entire drawing process, that is, to reduce the number of times the copper alloy bar is drawn, avoid unnecessary losses, and increase the service life of the central drawing die 23. The number of drawing dies 23 used can be adjusted according to the deformation amount required for drawing of the copper alloy bar, further avoiding unnecessary losses. The friction between the copper alloy bar and the drawing die 23 is reduced by lubricating oil, making the drawing surface smoother. At the same time, the lubricating oil is used to remove the debris generated on the surface of the copper alloy bar during the drawing process to prevent it from affecting the next drawing effect and avoiding unnecessary wear of the drawing die 23. The lubricating oil mixed with the debris is filtered and continued to be used to ensure that the lubricating oil for lubricating the copper alloy bar and the drawing die 23 is clean and avoid waste of lubricating oil.

The extrusion plate 253 faces one end of the slot 251 and is located in the extrusion spring 252. A positioning bent rod 258 is fixedly installed on the part and slides through the slot 251. A plurality of guide bent grooves corresponding to the positioning bent rod 258 are evenly arranged at the left end of the slot 251; the squeezing plate 253 supports the grid baffle 254 through the squeezing spring 252, so that the grid baffle 254 is vertical in the slot 251. When the grid baffle 254 needs to be taken out, the control plate 255 is pressed to the left to tilt the grid baffle 254, and then the grid baffle 254 is taken out. As the grid baffle 254 and the stacking plate 257 gradually tilt to the left, the debris moves to the left to the corner between the grid baffle 254 and the stacking plate 257 under the action of gravity, preventing the debris from moving to the right and falling downward, thereby smoothly cleaning all the debris attached to the surface of the grid baffle 254.

[0046] Working principle of the present invention: Step 1: During the drawing process, lubricating oil is coated on the surface of the copper alloy rod through the chip removal rack 28, and lubricating oil is introduced into the interior of the drawing die 23 through the oil delivery rack 24.

[0047] Step 2: The copper alloy camphor material after preliminary drawing extends out of the drawing die 23 and enters the adjacent chip removal rack 28 for chip removal. Through the cooperation of the oil drip rack 27, the small amount of debris remaining on the surface of the copper alloy camphor material after chip removal is brought into the oil tank 25 for filtration to facilitate reuse.

[0048] Step 3: After the copper alloy rod extends from the rightmost drawing die 23, a clamping tool is used to fix the protruding part of the copper alloy rod and pull it to the right to speed up the drawing efficiency of the copper alloy rod. When the length of the copper alloy rod after drawing reaches the required length, it is cut by a cutting machine, removed and collected.
