Embodiment Construction
[0022] The present invention will be further described in detail below through the specific examples, the following examples are only descriptive, not restrictive, and cannot limit the protection scope of the present invention with this.
[0023] A precise steel pipe flat head method, the main steps are: front alignment, that is, through the first alignment roller table 5, the first steel pipe transported by the feeding cooling bed frame 7 and the pipe turning device 9 in the previous process is forwarded to the The first flat head machine positioning device place 1 makes the front end of the first steel pipe flush with the first flat head machine 2. Pipe transfer, that is, through the pipe transfer device 3, the first steel pipe on the first alignment roller table is moved laterally to the first flat head support 8 and the front end of the first steel pipe is placed in the first flat head machine, and the first steel pipe is clamped by the first flat head machine. The clampin...

The invention belongs to the manufacturing field of steel pipes, and relates to a precise steel pipe head leveling method. The precise steel pipe head leveling method comprises the main steps of front alignment, pipe movement, front end head leveling, pipe movement, back alignment, pipe movement, precise positioning, precise sizing and back end head leveling. A precise steel pipe head leveling device comprises a head leveling chamfering device, and further comprises a standard positioning device, wherein the head leveling chamfering device consists of a first head leveling machine, a second head leveling machine, a first alignment roller way, a second alignment roller way, a first head leveling bracket, a second head leveling bracket and pipe moving devices; the first alignment roller way, the first head leveling bracket, the second alignment roller way and the second head leveling bracket are arranged side by side in sequence; the first head leveling machine is arranged in front of the first head leveling bracket, and is coaxial with the same; the second head leveling machine and the first head leveling machine are oppositely arranged behind the second head leveling bracket, and are coaxial with the same; the pipe moving devices are uniformly distributed between the first head leveling machine and the second head leveling machine; and the standard positioning device and the second head leveling machine are oppositely arranged on the axle of the second head leveling bracket. The method and the device are precise in sizing and strong in innovativeness.
Description
technical field [0001] The invention belongs to the technical field of steel pipe manufacturing, and in particular relates to a precision steel pipe flat head method and device. Background technique [0002] In the production of steel pipes, especially welded pipes, the cutting to length is mainly realized by flying saws, and it is usually impossible to cut to length in the flat end chamfering process. Due to the limitation of the flying saw function, its error range is relatively large, usually plus or minus six millimeters, which is far from meeting the needs of some demanding users. For a long time, the low precision of steel pipe sizing has become a stubborn problem in the pipe industry. In order to meet the needs of users, a lot of rework is often required, which is time-consuming and laborious. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide a method and device for precise steel pi...
