Abstract
Disclosed is a portable electric cutting tool for tapering steel pipes. Both ends of the main shaft of the electric cutting tool are respectively provided with a braced hand wheel, and an expanding tyre, and both sides of the expanding tyre are right and left threads, making the side of the inner diameter of a steel tube be fixed with manufactured steel tubes. The cutting tool of the groove is a high speed steel tool. The electric cutting tool is practical for the groove cutting process of steel tubes with major diameters of 100-400 such as heating furnace tubes which are difficult for the groove to be cut on machine tools.
Description
The utility model belongs to the electric cutting tool that the steel pipe finished edge is used.
For the large diameter steel pipe of the φ 100～400 of furnace tubing and so on, before welding, generally all become the groove of different shape in mouth of pipe machining, be beneficial to reduce weld defect, fully through welding.
But, the groove cutting element of large diameter steel pipe up to now, major part is by anchor clamps grinding to be carried out with the angle emery wheel in the fixing back of steel pipe.Its machining efficient is low, noise is big and with the flying upward of grinding metallic dust, influence work situation.
The purpose of this utility model provides a kind of processed steel pipe by stretching parts stretching, fixing, the electric cutting tool that carries out turning then with high-speed steel tool.
The utility model is finished as follows.
One end of main shaft is equipped with the bloated tire that both sides are left and right screw thread, and the other end of main shaft is fixed with the stretching handwheel.Rotation stretching handwheel because the tire both sides of expanding are left and right sides screw thread, so the tire that expands radially stretching thereupon, at internal side diameter the processed steel pipe stretching of different-diameter, fixing.
On the other hand, cutting part is housed on main shaft, this cutting part is concentric with main shaft.Cutting part is made up of rotary axle box, knife rest, cutter and feed handwheel.Rotary axle box is installed on the main shaft movingly, and the knife rest of fixed cutting tool is installed on the rotary axle box, and the feed handwheel utilizes screw thread to be installed on the main shaft.When rotary axle box was done clockwise by the drive disk assembly drive or counterclockwise rotated, the cutter on the knife rest is rotation thereupon also.Rotate the feed handwheel simultaneously, the turning cylinder interplanting is moved axially by thrust bearing.So just can control the depth of cut in the limit, the cutting of steel pipe groove is carried out on the limit, thereby reaches the purpose of this utility model.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Accompanying drawing 1 is the longitudinal sectional drawing of a kind of concrete structure of the utility model.(1) is the tire that expands among the figure, and (2) are that the knife rest, (3) that are fixed with cutter are that main shaft, (4) are that rotary axle box, (5) are that feed handwheel, (6) are that stretching handwheel, (7) are that drive disk assembly, (8) are processed steel pipes.
Left end at main shaft (3) is equipped with bloated tire (1), and the both sides of the tire (1) that expands are left and right screw thread.The right-hand member of main shaft (3) is fixed with stretching handwheel (6).Rotation stretching handwheel (6), because the tire both sides of expanding are left and right sides screw thread, therefore along with the rotation of main shaft (3), the tire (1) that expands is radially just freely stretching, can be at internal side diameter processed steel pipe (8) stretching of different-diameter, fixing.
Rotary axle box (4) is housed on the main shaft (3) movingly, and this rotary axle box (4) is concentric with main shaft (3).The knife rest (2) of fixed cutting tool is housed on the rotary axle box (4), and feed handwheel (5) utilizes screw thread to be installed on the main shaft (3).When rotary axle box (4) was done clockwise by drive disk assembly (7) drive or counterclockwise rotated, the knife rest of fixed cutting tool (2) is rotation thereupon also.Rotate feed handwheel (5) simultaneously, rotary axle box (4) is moved axially simultaneously by thrust bearing.So just can control the depth of cut in the limit, the machining of steel pipe groove is carried out on the limit.
After adopting electric cutting tool of the present utility model, since processed steel pipe by the stretching parts at internal side diameter stretching, fixing, so for be difficult to clamping on lathe, fixing steel pipe need add man-hour as groove, this electric cutting tool can be moved to the scene, carry out stretching, fixing easily.In addition,,, reduce labor intensity, improve working environment so existing shortcoming when having avoided employing angle wheel grinding groove can improve work efficiency and groove face fineness because the groove of steel pipe is to be cut by the high-speed steel tool that is loaded on the knife rest.Therefore, this electric cutting tool is very practical for the groove processing of 100～400 large diameter steel pipes of the φ such as furnace tubing.
Claims (2)
1, a kind of electric cutting tool of forming by motor, drive disk assembly, stretching parts, cutting part etc. that supplies the steel pipe finished edge to use, the stretching parts that it is characterized in that fixing processed steel pipe are made up of the stretching handwheel that is positioned at the main shaft two ends and the tire that expands, and the both sides screw thread of bloated tire is left and right screw thread.
2,, it is characterized in that the cutter in the cutting part is a high-speed steel tool according to the described electric cutting tool of claim 1.
