Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of steel pipe forming, in particular to a steel pipe forming device with correction positioning function. BACKGROUND

[0002] Steel pipes are divided into seamless steel pipes and seamed steel pipes, and most of the seamed steel pipes are processed by steel pipe forming devices. The specific steps are as follows: flattening first, then coiling, welding, and finally forming a steel pipe of a specific size through edge trimming, cooling and cutting.

[0003] The technical solutions of the steel pipe forming devices on the market are similar to those in the following patents: "CN113695433A Steel pipe forming equipment (publication date: 2021.11.26)" and "CN215355520U Steel pipe forming die (publication date: 2021.12.31)", but in actual work, the following problems are often encountered: first, the steel strip may deviate during movement due to external factors or factors of the machine itself, and the existing steel pipe forming device usually does not have a correction positioning function, which affects subsequent processing; second, according to the national standard, the width of the steel strip has a certain allowable deviation, and as the width of the steel strip increases, the allowable deviation also increases. The current steel pipe forming device usually uses the steel strip directly without processing, which causes unstable product quality and is not conducive to improving product quality; third, the steel strip forms a pipe blank after coiling, and the pipe blank is formed into a steel pipe after passing through the high-frequency welding mechanism. At this time, the steel pipe surface will carry weld beads. The current steel pipe forming device usually uses a scraper to remove the weld beads, and when the scraper is damaged, it often needs to be replaced, which greatly affects the work efficiency.

[0016] The pipe blank is shaped into a steel pipe when passing through the high-frequency welding mechanism, and the steel pipe surface carries weld bumps. When the weld bumps on the steel pipe pass through the surface treatment mechanism, the weld bumps on the steel pipe surface can be removed by the second cutter on the second cutter seat. Since the group of second cutters close to the high-frequency welding mechanism has the maximum working intensity, damage is prone to occur. Therefore, the surface detection assembly is arranged outside the group of second cutter seats close to the high-frequency welding mechanism. The surface detection assembly can be selected from existing technologies, such as visual detection technology or infrared detection technology.

[0018] When the group of second cutters close to the high-frequency welding mechanism is damaged, the first sliding seat and the second sliding seat are driven to move in the two groups of second sliding grooves by the second cylinder. Then, the two groups of second cutters are rotated by the reversing motor and the first bevel gear transmission assembly, so as to change the positions of the damaged cutters and the new cutters.

The first induction block is aligned with the second induction block when the surface treatment mechanism works.

[0020] The application also provides an induction assembly, and a horizontal inductor and a battery are arranged in the second sliding seat; in normal operation, the first induction block, the second induction block, the horizontal inductor and the battery form a loop, the position of the movable plate is detected by the horizontal inductor, and the position of the movable plate is related to the position of the second cutter, that is, when the movable plate is in a horizontal state, the second cutter is in a vertical state; when the second cutter is deflected due to an accident in the operation of the reversing assembly, the movable plate will be deflected synchronously, at this time, the first induction block and the second induction block cannot be aligned, the first induction block, the second induction block, the horizontal inductor and the battery will also be disconnected, and the position of the second cutter can be determined in time by the induction assembly, so that the second cutter cannot only remove the weld bumps on the surface of the steel pipe but also cause damage to the steel pipe.

[0050] As Figures 9-11 The induction assembly 6421 comprises a movable plate 64211, a first induction block 64212, a second induction block 64213 and an induction groove 6422, the induction groove 6422 is arranged in the second sliding seat 642, the movable plate 64211 is arranged in the induction groove 6422, the two ends of the movable plate 64211 are connected with the two sets of second cutters 621 through two sets of second bevel gear transmission assemblies respectively, the first induction block 64212 is arranged at the two ends of the movable plate 64211, the second induction block 64213 is arranged at the two ends of the induction groove 6422, and the first induction block 64212 is aligned with the second induction block 64213 when the surface treatment mechanism 6 works.

The offset steel belt is corrected and positioned through the pretreatment mechanism 3, and the cutting assembly is arranged in the pretreatment mechanism 3. The distance between the standard value and the actual value of the steel belt can be further reduced on the basis of meeting the national standard, thereby improving the stability and overall quality of the product. The steel belt is continuously rolled into a pipe blank through the roll mechanism 4, and the pipe blank is formed into a steel pipe when passing through the high-frequency welding mechanism 5. At this time, the steel pipe surface will carry weld beads. When the weld beads on the steel pipe pass through the second cutter 621 on the second tool holder 62 of the surface treatment mechanism 6, the weld beads on the surface of the steel pipe can be removed. The present application is provided with a surface detection assembly outside a group of second tool holders 62 close to the high-frequency welding mechanism 5. When the surface detection assembly detects that the weld beads on the steel pipe are not completely removed after passing through a group of second cutters 621 close to the high-frequency welding mechanism 5, the two groups of second tool holders 62 are driven to move away from the high-frequency welding mechanism 5 through the reversing assembly 64, and at the same time, the two groups of second tool holders 62 will rotate to make the new cutter in operation contact the weld beads on the steel pipe. The steel pipe is cooled through the cooling mechanism 7, and the diameter and length of the steel pipe are adjusted through the sizing mechanism 8 and the sizing mechanism 9.
