Combination type inner-burr cleaning and weld guiding device

Abstract

The invention discloses a combination-typed internal burr removing and welding seam guiding device, comprising a fixed bracket, a welding seam guiding roller assembly, and a cutter rod assembly; wherein, the fixed bracket is arranged on the side surface of a forming frame; a large trailing plate which can slide upwards and downwards is arranged on the fixed bracket; one side of the large trailingplate is fixed with the welding seam guiding roller assembly and the other side thereof is provided with a small trailing plate in an upper and lower sliding way; the small trailing plate is providedwith an oil cylinder and a cutter rod assembly which are connected with each other. The combination-typed internal burr removing and welding seam guiding device leads the welding seam guiding roller assembly and the cutter rod assembly used for removing the internal burr to be effectively combined together, reduces the parts, simplifies the structure, increases the whole strength, has extremely convenient installation usage and specification replacement, improves the product quality, production efficiency and yield in the production and leads the production cost of the enterprise to be greatlyreduced.

Description

【Technical field】 [0001] The invention relates to the field of high-frequency straight seam welded pipe processing equipment, in particular to a device combined with in-line deburring of steel pipes and weld seam guide rollers. 【technical background】 [0002] On the ERW630 high-frequency straight seam welded pipe production line, due to the requirements of the production process, the steel pipe will produce large internal and external burrs during the welding process. According to the requirements of the relevant steel pipe quality standards, the internal and external burrs of the weld must be removed. After the frame, there is a cleaning device for internal and external burrs. The removal of internal burrs adopts the method of adding a scraping knife rod inside the steel pipe. While welding, the movement of the steel pipe is used to directly scrape and remove the internal burrs without cooling the weld seam and the internal burrs. Since the scraper rod is inside the steel ...

AI Technical Summary

Problems solved by technology

[0003] 1. The overall structure of the internal burr device is difficult to install and debug, and the operation time for replacement and debugging is close to one shift, which is very unfavorable for improving production efficiency

[0004] 2. The maximum length of the original cutter bar is 8.7 meters. In order to adapt to different production specifications, it is assembled from 3 to 4 sections. It is difficult to fix, and the cutter head part has a large swing and twist, which makes it difficult to remove internal burrs to meet the quality standards.

[0005] 3. The original cutter bar is divided into three types according to different steel pipe specifications, which are respectively suitable for φ212.5-φ298.5mm, φ312.5-φ425.4mm, φ437.5-φ625mm. -20mm each has nearly 8 kinds of small specifications, and there are dozens of spare parts suitable for different specifications and different wall thicknesses on the tool holder. The preparation of spare parts and on-site installation and commissioning consume a lot of financial resources, manpower and time.

[0006] 4. The internal burr cutting device is easily damaged. The original internal burr cutting device on the equipment has failed, resulting in frequent blockage of the welding tumor, resulting in frequent shutdowns due to the inability to remove the internal burr

[0007] 5. The cutter head is easily damaged and replaced frequently, which affects the normal production speed

[0008] 6. The original welding seam guide roller device cannot function normally, which affects the quality of the welding seam
