Problems solved by technology

If the milling depth is too shallow, skip milling will occur and affect the final product quality
[0004] In actual production, the outer diameter of the tube blanks cast in the same batch has a maximum difference of 0 to 1mm. The head of the next tube blank with different outer diameters withstands the tail of the previous one, and one by one enters the milling process. In the leather equipment, since the outer diameter of each tube blank has not been measured, and it is difficult to adjust the reduction of the milling cutter online, and the operator stops the adjustment and it is cumbersome, in the actual production process, the same batch can only be cleaned according to milling. The principle of all outer diameter defects of the tube blank is to adjust the reduction of the milling cutter for milling. Usually, the single-side milling amount reaches 0.8-1mm, which is far greater than the thickness of the defect layer, resulting in a very low product yield in the milling process and aggravated the problem. Milling cutter wear and equipment loss

Embodiment 1

[0042] The processing equipment of present embodiment sizing milling skin, its structure is as Figure 1 to Figure 7 Shown; including pinch straightening device 1, sizing device 2, milling device 4 and output pinch device 5; pinch straightening device 1, sizing device 2, milling device 4 and output pinch device 5 connect in turn.

[0043] The pinch straightening device 1 includes a straightening roller group one 11 and a straightening roller group two 12; the straightening roller group one includes a number of straightening rollers one; Roller 1 and straightening roller 2 are respectively connected to the rotary drive module 1 to realize reverse rotation between straightening roller 1 and straightening roller 2 12; each straightening roller 1 and straightening roller 2 are arranged alternately on both sides of the tube blank . The total number of straightening roller 1 and straightening roller 2 is greater than five to ensure sufficient straightening and clamping to prevent ...

Embodiment 2

[0056] In the processing method of sizing and milling in this embodiment, a pinch straightening process and a sizing process are added before the milling process;

[0057] The pinching and straightening process refers to that the tube blank is clamped and forwarded, and the tube blank is flattened by the reverse bending action during the forward movement process to realize the tube blank straightening;

[0058] The sizing process refers to adopting a number of sizing rollers to roll around the outer surface of the tube blank to press the outer diameter of the tube blank to a set value.

[0059]Compared with the traditional processing method that directly enters the milling process without pretreatment, the processing method of the present invention adds a pinch straightening process and a sizing process before the milling process; the straightening process makes the tube blank have good straightness , to ensure that the tube blank can smoothly enter the device for the sizing p...

Abstract

The invention provides a machining device for fixed-diameter surface milling. The machining device is characterized by comprising a clamping, conveying and straightening device, a diameter fixing device, a surface milling device and a discharging clamping and conveying device, the clamping, conveying and straightening device is used for clamping and conveying a pipe blank and conducting reverse bending straightening on the pipe blank so as to remove bending of the pipe blank, the diameter fixing device is used for doing the rolling movement around the surface of the pipe blank and pressing the pipe blank so that the outer diameter of the pipe blank can reach the preset outer diameter value, the surface milling device is used for conducting surface milling on the outer surface of the pipe blank, the discharging clamping and conveying device is used for discharging the pipe blank, and the clamping, conveying and straightening device, the diameter fixing device, the surface milling device and the discharging clamping and conveying device are sequentially connected. By means of the machining device, the outer diameter difference, caused by casting, of different pipe blanks can be removed, the milling depth is greatly reduced, the pipe blank surface machining amount is reduced, and the material utilization rate and the product yield are increased. The invention further provides a machining method for fixed-diameter surface milling; and by means of the machining method, the milling depth can be greatly reduced, the pipe blank surface machining amount can be reduced, and the material utilization rate and the product yield can be are increased.

Description

technical field [0001] The invention relates to the technical field of milling and skinning of tube blanks, and more specifically, relates to a processing equipment and a processing method for sizing and milling skins. Background technique [0002] The surface of the tube blank after continuous casting generally contains a small amount of oxides and residues; and due to the wear of the casting mold, the surface of the tube blank will also become rough and may appear fine cracks. These defects, if not eliminated, will lead to quality problems in the final product. Therefore, in the casting and rolling production line widely used at present, surface machining (commonly used milling or turning) equipment is usually arranged between the continuous casting equipment and the rolling equipment to remove surface defects and oxide layers of the tube billet; usually surface defects And the unilateral thickness of the oxide layer is about 0.3mm. [0003] However, continuous casting t...
