The production and manufacture of the seamless thin-wall tube blank at present are mainly finished by multiple stretching, after each stretching, auxiliary processes such as cleaning, heat treatment and the like are carried out, then the next stretching process is carried out, and after multiple stretching, the seamless thin-wall tube blank is manufactured. Because the field of high-precision instrument measurement is related to, the corrugated pipe also has quite high precision requirement in the process of machining and forming.
The applicant filed a single application at 2017, 9, 13, with the following numbers: CN201710821499.6, name: the invention discloses a composite stretch forming method of a corrugated pipe blank. During the subsequent research and exploration process of the inventor, the applicant finds that the following technical defects exist in the application:
firstly, the station that has 8 circumference period equidistant divisions in this application is used for realizing 8 stretching processes of pipe respectively, and after the last stretching process was accomplished, just need hold up the work piece on this station and drive its rotatory behind 45 through servo motor and install on the station of next process, wherein, each complete process has included four steps, is respectively: the method comprises the following steps of descending a workpiece (used for transporting the workpiece to a station), stopping the workpiece (used for providing sufficient time to complete stretching operation), ascending the workpiece (firstly supporting the workpiece which completes the stretching operation), rotating the workpiece by 45 degrees (used for switching stations), and then repeatedly and periodically entering the next stretching process, wherein the four steps all relate to the displacement of the workpiece. Therefore, the inventor tries to save the capital cost of the equipment and to make the machining consistency better if only one motor is used to provide the displacement process for each step of the workpiece and the motor is not required to be introduced into the control system and is only required to be continuously started to complete all periodic work.
In addition, in the positioning process, the guide post and the guide sleeve are adopted for offset correction, but the inventor finds that in the process of using the equipment for a long time, because the use frequency of the equipment is very high, the guide post needs to be inserted into the guide sleeve in advance to complete positioning in each station switching process, the edge of the guide post is easy to wear in a frequent insertion process, although the initial wear amount is small, the positioning effect cannot be greatly influenced, the corrugated pipe belongs to a high-precision part, so the precision control is very important, the guide post is easy to generate an off-axis phenomenon in the deviation rectifying and impacting process of impacting, the positioning precision is not high, and if the problem can be avoided, the yield of the corrugated pipe can be greatly improved.
