Abstract

The present invention relates to the technical field of copper pipe production equipment, specifically a production equipment for copper and copper alloy special-shaped pipes, including a grinding mechanism, a first cleaning mechanism, a second cleaning mechanism, a first extrusion mechanism, and a second extrusion mechanism. The rotation of the motor drives the grinding block to grind the welded seam of the copper pipe.

Description

Technical Field

[0001] The present invention relates to the technical field of copper pipe production equipment, and specifically relates to a production equipment for copper and copper alloy special-shaped pipes. Background Art

[0002] Special-shaped pipes are generally distinguished according to the cross-section. In terms of materials, they can be divided into seamless steel pipe special-shaped pipes, aluminum alloy special-shaped pipes, and plastic special-shaped pipes. The development of special-shaped pipes is mainly the development of product varieties, including cross-section shapes, materials, and properties. The extrusion method, inclined die rolling method, and cold drawing method are effective methods for producing special-shaped pipes. It is applicable to the production of special-shaped pipes of various cross-sections and materials. In order to produce a wide variety of special-shaped pipes, various production means must also be available. In the 1990s, on the basis of only cold drawing in China, dozens of production methods such as roll drawing, extrusion, hydraulic pressure, rotary rolling, spinning, continuous rolling, rotary forging, and die-less drawing were developed, and new equipment and processes were continuously improved and created.

[0003] For special-shaped pipe production equipment, when extruding a round pipe with a weld seam into a special-shaped pipe, the weld seam needs to be polished. A part of the debris generated after polishing will adhere to the upper surface of the copper pipe, which will affect the subsequent extrusion forming. When extruding a round pipe into a square pipe, the front-end pipe needs to be extruded and formed, otherwise the round pipe cannot be placed into the roller of the square pipe and thus cannot be extruded and formed. Summary of the Invention

[0004] Aiming at the problems in the prior art, the present invention provides a production equipment for copper and copper alloy special-shaped pipes.

[0005] The technical solution adopted by the present invention to solve its technical problems is: a production equipment for copper and copper alloy special-shaped pipes, including a polishing mechanism, a first cleaning mechanism, a second cleaning mechanism, a first extrusion mechanism, and a second extrusion mechanism.

While the motor rotates, it will drive the rubber ball to move upward, so that the water in the water inlet pipe will flow out to wash the debris on the copper pipe. While the motor rotates, it will drive the screw rod to rotate to clean the debris out of the equipment, and the water used for cleaning will be discharged from the second water outlet pipe through the small holes. When extruding the copper pipe from a round pipe into a square pipe, the front end needs to be extruded to fit into the roller. When the front end of the copper pipe reaches the upper end of the hydraulic telescopic rod, the hydraulic telescopic rod moves upward to drive the telescopic body to extrude the upper and lower ends of the copper pipe, and at the same time, the extrusion block squeezes the copper pipe inward, so that the front end of the copper pipe will be extruded into a square pipe.

The leftward movement of the rack drives the first sliding rod to move leftward. The leftward movement of the first sliding rod will compress the first spring. The leftward movement of the first sliding rod drives the first steel wire rope to move upward. The upward movement of the first steel wire rope will pull the rubber ball upward. In this way, water will flow out from the water inlet pipe to wash away the debris generated by grinding the upper surface of the copper pipe.

[0008] Specifically, the second cleaning mechanism includes a second bearing. The side wall of the second bearing is fixedly connected to the first outer shell. One end of the first outer shell is fixedly connected to the second outer shell. One end of the first rotating shaft is fixedly connected to the screw rod.

One end of the rotating pin is rotatably connected to the extrusion block. One end of the second steel wire rope is fixedly connected to the telescopic body. When the telescopic body moves upward for extrusion, it will drive the extrusion block to move upward. When the two extrusion blocks come into contact, they will squeeze and drive the second sliding rod to move downward. The downward movement of the second sliding rod will perform extrusion. In this way, the downward movement of the second sliding rod drives the second steel wire rope to move upward. The upward movement of the second steel wire rope will pull the extrusion block to move inward to extrude the copper pipe. In this way, the front end of the copper pipe has become square after being extruded twice. In this way, when the copper pipe passes through the second roller, it can fit well. The copper pipe rolled by the second roller is square.

The leftward movement of the first sliding rod 23 drives the first steel wire rope 29 to move upward. The upward movement of the first steel wire rope 29 will pull the rubber ball 213 upward. In this way, water will flow out from the water inlet pipe 212 to wash away the debris generated by grinding the upper surface of the copper pipe 110. While the first rotating shaft 12 is rotating, it will drive the screw rod 34 to rotate. The rotation of the screw rod 34 clears the debris out of the device, and the water is discharged from the second outlet pipe through the small holes 35. When squeezing the copper pipe 110, start the hydraulic telescopic rod 42 to move downward, which will drive the telescopic body 43 to squeeze the copper pipe 110 up and down. While the telescopic body 43 is squeezing upward, it will drive the extrusion block 51 to move upward. When the two extrusion blocks 51 come into contact, they will squeeze and drive the second sliding rod 52 to move downward. The downward movement of the second sliding rod 52 will exert pressure. In this way, the downward movement of the second sliding rod 52 drives the second steel wire rope 56 to move upward. The upward movement of the second steel wire rope 56 will pull the extrusion block 51 to move inward to squeeze the copper pipe 110. In this way, the front end of the copper pipe 110 has become square after being squeezed twice. In this way, when the copper pipe 110 passes through the second roller, it can fit well.
