Technical Field

[0001] The invention relates to the technical field of pipe head protection devices, in particular to a pipe head protection device for annealing a copper pipe. Background Art

[0002] Copper pipe is a kind of pipe material. It has the characteristics of good electrical conductivity and thermal conductivity. It is the main material for conductive accessories and heat dissipation accessories of electronic products, and has become the first choice of modern contractors for the installation of tap water pipes, heating and cooling pipes in all residential commercial houses. In the processing of copper pipes, it is necessary to anneal the copper pipes, heat the copper pipes to a temperature where phase change or partial phase change occurs, and then slowly cool them after insulation. In order to eliminate the organizational defects of the copper pipes, improve the organization to make the composition uniform and refine the grains, improve the mechanical properties of copper, reduce residual stress, and at the same time improve plasticity and toughness, and improve cutting performance.

[0003] The inventors have found that when using an annealing device to anneal a copper tube, the copper tube is usually heated to a relatively high temperature. During the heating process, the copper tube moves because of its high temperature and fragile surface structure. If it is accidentally hit, it may break and deform. In addition, since the heat source for heating the copper tube is close to the top of the copper tube, the different cooling times at the top and bottom of the copper tube away from the heat source will affect the annealing effect. Summary of the invention

[0004] The present invention is to solve the problem that in daily work, when an annealing device is used to anneal a copper tube, the copper tube is usually heated to a relatively high temperature. During the movement of the copper tube after the heating is completed, the temperature of the copper tube is relatively high and the surface structure is relatively fragile. If the copper tube is accidentally hit, it may cause the copper tube to break and deform. In addition, since the heat source for heating the copper tube is close to the top of the copper tube, the cooling time of the top and bottom of the copper tube is different after being away from the heat source, which may affect the annealing effect. Therefore, a tube head protection device for annealing a copper tube is proposed.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a tube head protection device for copper tube annealing, comprising a machine rod and a heating device, a motor is arranged at one end of the outer surface of the machine rod, a rotating shaft is fixedly connected to the output end of the motor, a carrying plate is fixedly connected to the outer surface of the rotating shaft, a plurality of placement grooves are provided on the outer surface of the carrying plate, a copper tube body is arranged inside the placement groove, a heat pipe is arranged at one end of the outer surface of the heating device, a protective device is arranged on one side of the outer surface of the carrying plate, the protective device comprises a box body, a gas pipe is fixedly connected to the top end of the outer surface of the box body, the gas pipe is a high temperature resistant hard pipe, a groove plate is fixedly connected to the end of the outer surface of the gas pipe away from the box body, and two semicircular plates are fixedly connected to the bottom end of the outer surface of the groove plate.

[0006] The effects achieved by the above components are as follows: by setting the slot plate, when heating the copper tube body, the copper tube body is first placed inside the placement slot on the carrier plate, the operating motor drives the rotating shaft to rotate so that the carrier plate drives the copper tube body to move to the heat pipe, and the heat pipe is heated by the heating device to anneal the copper tube body. After the annealing of the copper tube body is completed, it will pass between the slot plate and the two semicircular plates. The slot plate and the two semicircular plates protect the copper tube body in a high temperature state to avoid collision of the copper tube body as much as possible.
