Description

Technical Field

[0001] The invention relates to the technical field of pipe making equipment, and in particular to an edge milling machine device for a pipe making machine. Background Art

[0002] Edge milling is the first step in the pipe making process, and its main function is to finely process the edges of metal plates. Through edge milling, the edge of the pipe can be made flat and smooth, laying a good foundation for subsequent welding, processing and other processes. The edge milling of the pipe making machine plays an important role in the manufacturing process of metal products. It is not only related to the quality, precision and production efficiency of the product, but also directly affects the life of the equipment and the economic benefits of the enterprise. However, in the prior art, the processing of pipe fittings is all done by manual loading, and the pipe fittings are prone to displacement when passing through the milling cutter disc, and the placement of the pipe fittings needs to be manually adjusted. The manual adjustment method is not only labor-intensive and has low processing precision, but also easily affects the processing qualification rate and reduces production efficiency. In addition, the existing milling device used in the pipe making machine has a single milling angle, poor flexibility, and is prone to offline beveling problems.

[0003] In order to solve the deficiencies of the prior art, people have conducted long-term exploration and proposed various solutions. For example, a Chinese patent document discloses a milling device for pipe processing [CN201711234789.7], which includes a base, a working mechanism, a milling mechanism and a control mechanism. The base is fixed with a left milling mechanism, a working mechanism and a right milling mechanism from left to right, and the left milling mechanism, the working mechanism and the right milling mechanism cooperate with each other. The base is also provided with a control mechanism, and the left milling mechanism, the working mechanism and the right milling mechanism are connected to the control mechanism. The working mechanism includes a workbench, a pusher and a positioning track. The milling mechanism includes a milling cutter disc, and the milling cutter disc cooperates with the workbench.

[0004] The above scheme solves to a certain extent the problem in the prior art that pipe fittings are prone to displacement when passing through the milling cutter disc, and the manual adjustment method is not only labor-intensive and has low processing accuracy, but also easily affects the processing qualification rate. However, the scheme still has many shortcomings, such as: the milling angle is single, the flexibility is poor, and the problem of offline beveling is prone to occur. Summary of the invention
