The processing method of the fender support device provided by the invention comprises the following steps of:
step S1: and machining a support elbow 1 and a base 2. For the processing of the supporting bent pipe 1, firstly, the pipe is cut into a pipe blank with a required size, then, the end part of the pipe blank is chamfered, and finally, the pipe blank is bent into the L-shaped supporting bent pipe 1 by using a pipe bending machine. The base 2 is formed by machining the blank material with a lathe, that is, the blank material is machined with the boss 22, the base plate 21 and the reinforcing ribs 23.
Step S2: the support elbow 1 and the base 2 are welded into a whole by friction welding. Since the support elbow 1 has a large volume and is not easy to rotate, it is preferable to fix the support elbow 1 and rotate the base 2, so that heat is generated by friction between the base 2 and the connection end of the support elbow 1, and the base 2 and the support elbow 1 are welded together.
Specifically, as shown in fig. 5, the step S2 includes:
step S21: the connecting end of the support elbow 1 is brought close to the welding end of the base 2. Specifically, as shown in fig. 3, the connecting end of the support elbow 1 is engaged with the welding end of the boss 22, and the connecting end of the support elbow 1 is sleeved on the welding end of the boss 22.
Step S22: the torque is input, so that the welding end of the connecting end of the support elbow 1 and the base 2 rub against each other. Specifically, the support elbow 1 is fixed, and then the base 2 is driven to rotate, so that the surfaces of the support elbow 1 and the boss 22 rub against each other to remove oxides and various impurities attached to the surfaces, and at the same time, as the heat gradually increases, the uneven portions of the contact surfaces of the support elbow 1 and the boss plastically deform, so that crystal grains are broken, and a clean and smooth contact surface is formed.
Step S23: and judging whether the real-time welding temperature reaches the preset welding temperature. Specifically, along with the continuous rotation of the base 2, more and more heat is generated between the boss 22 and the support elbow 1, so that the real-time welding temperature of the contact portion between the boss 22 and the support elbow 1 is increased, in the process, the plastic deformation of the contact portion between the boss 22 and the support elbow 1 is gradually increased, and a mutual "bonding" phenomenon (i.e., local welding) of metals starts to occur, when the real-time welding temperature reaches the preset welding temperature, the step S24 is performed, otherwise, torque is continuously input to the base 2 until the real-time welding temperature reaches the preset welding temperature position.
It should be noted that the real-time welding temperature can be measured by a temperature sensor in the prior art.
Step S24: stopping inputting the torque, and applying an upsetting force to the support elbow 1 and the base 2 to weld the support elbow 1 and the base 2 into a whole. Specifically, when the welding temperature reaches the preset welding temperature, the welding end of the boss 22 and the connecting end of the support bent pipe 1 have high plasticity, then the relative rotational motion is stopped rapidly (i.e., the input torque is stopped), the welding end of the boss 22 and the connecting end of the support bent pipe 1 have high plastic deformation, atoms on the surfaces where the two contact each other have mutual diffusion and intercrystalline connection phenomena, and form common recrystallization, an intermediate compound and a small amount of recrystallized grains, then an upsetting force is applied in the axial direction of the connecting end of the boss 22 and the support bent pipe 1, as shown in fig. 3, a flash 7 is extruded between the two, and finally the friction welding of the support bent pipe 1 and the base 2 is realized.
It should be noted that the preset welding temperature is determined according to practical factors such as the manufacturing materials of the base 2 and the support elbow 1.
In addition, after the welding of the support elbow 1 and the base 2 is completed in batch, the current batch of fender support devices should be sampled and subjected to destructive detection and nondestructive detection, wherein the destructive detection indexes generally comprise the following items: bending, stretching, compression resistance, metallographic structure, fatigue resistance, hardness, shearing, photomicrography and the like; the non-destructive testing indicators generally include the following items: ultrasonic inspection, penetration, leak test, visual inspection, surface etching, pressure testing, hardness and size, and the like.
And after the sampled sample is qualified, marking, packaging, labeling and warehousing and storing the whole batch of fender supporting devices in sequence.
The fender support device and the processing method thereof provided by the invention are described in detail above. The principles and embodiments of the present invention are explained herein using specific examples, which are presented only to assist in understanding the method and its core concepts. It should be noted that, for those skilled in the art, it is possible to make various improvements and modifications to the present invention without departing from the principle of the present invention, and those improvements and modifications also fall within the scope of the claims of the present invention.
