Special material frame for oxygen-free copper pipe annealing

Abstract

The invention provides a special material frame for oxygen-free copper pipe annealing, and relates to the technical field of copper pipe machining. The special material frame for oxygen-free copper pipe annealing comprises a frame and a clamping device, wherein rolling wheels are uniformly and rotatably connected to the inner wall of the frame, the clamping device is arranged on the surface of the frame, and the clamping device comprises two connecting plates; and the two connecting plates are fixedly connected with the surface of the frame, the connecting plates are of L-shaped structures, limiting rods are slidably connected to the surfaces of the two connecting plates, a rectangular frame is fixedly connected to the ends, close to the rolling wheels, of the two limiting rods, and sliding blocks are uniformly and slidably connected into the rectangular frame. According to the invention, the problems that when the material frame is used for feeding a plurality of copper pipes, the copper pipes are likely to be tightly attached together, the contact positions of the copper pipes are likely to be not prone to annealing when the copper pipes are conveyed into annealing equipment, and therefore micro deformation possibly occurs between the machined copper pipes, and the product quality is affected, are solved.

Description

technical field [0001] The invention relates to the technical field of copper tube processing, in particular to a special material frame for oxygen-free copper tube annealing. Background technique [0002] Copper tubes, also known as copper tubes, are pressed and drawn seamless tubes. Copper tubes are light in weight, good in thermal conductivity, and high in low temperature strength. They are often used in the manufacture of heat exchange equipment such as condensers, and are also used in oxygen production equipment. Assembling low-temperature pipelines, small-diameter copper pipes are often used to transport pressurized liquids such as lubrication systems, oil pressure systems, etc., and pressure measuring tubes used as instruments. First choice for heating and cooling piping installations. [0003] When an annealing process is required for oxygen-free copper tubes, a material frame is usually used to complete the feeding of multiple copper tubes. When using a material fr...

Problems solved by technology

[0003] When an annealing process is required for oxygen-free copper tubes, a material frame is usually used to complete the feeding of multiple copper tubes. When using a material frame to feed multiple copper tubes, due to the copper tube and copper The tubes may be close together, transporting them to the annealing equipment will easily lead to the position where the copper tubes are in contact with each other is not easy to anneal, which may cause micro deformation between the processed copper tubes and the copper tubes, which will affect the quality of the product
