One-step molding process of roller bar stock on lathe

Abstract

The invention discloses a one-step molding process of a roller bar stock on a lathe. The process comprises the following steps of: leveling a right end surface by adopting an end surface cutter; after the end surface is leveled to an appointed size, digging a hole on the right side of a roller; cutting off by using a cut-off tool, and meanwhile, synchronously profiling the left chamfer from the outer diameter of the right chamfer; and after finishing slotting by a slotting tool which is a flat cutter and a 5-degree chamfering cutter, assisting a clamping head to clamp and twist off a roller. By adopting the method, the turning processing of all surfaces of the roller can be finished in one-step clamping, the processed roller is molded at one time and can be directly sent to a grinding procedure after being subjected to heat treatment. The one-step molding process of a roller bar stock on a lathe can be used for realizing the one-step turning and molding of the processed roller, saves the material handling time, combines the procedures, saves the labor power, avoids secondary clamping of the processed roller, improves the processing precision, improves the processing efficiency and saves the total processing time. After the process is applied to lathes, an operator can simultaneously operate 3-4 lathes, thus a large quantity of labor power is saved.

Description

technical field

[0001] The invention belongs to the technical field of mechanical processing, and in particular relates to a one-time forming process of a roller bar lathe. Background technique

[0002] In the prior art, the six-meter bar is rounded on the DDF3 lathe on the right end face after being abandoned, the right end face is flattened, the outer diameter spherical surface is profiled, and cut off. After cutting, 2 to 3 Small prongs with a length of about 4 mm, the turned rollers are processed on the DF9 lathe after being transported, the right end face is dug, the left side is rounded, and the left end face of the prong is flat. Currently, the rollers processed by this process The rollers cannot be formed once on a single lathe, the processing efficiency is low, and personnel are wasted. Contents of the invention

[0003] The object of the present invention is to provide a one-time forming process of a roller bar lathe which can realize the one-time turning and fo...

Embodiment Construction

[0014] The present invention is a roller bar lathe one-time molding process. The currently used process is bar feeding. The six-meter bar is loaded to the reference size, clamped by the workpiece shaft, and the servo controls the end face knife feed on the DF3 lathe. Make a flat end face on the right end face of the bar. After the flat end face reaches the specified size, dig a center hole on the right side of the roller through the end face knife to form a hole once. The servo controls the feed of the cutting knife to cut the roller. The copying knife copies the outer diameter of the roller and the chamfers on both sides, from right to left. After the copying is completed, the cutting knife still feeds. When the diameter of the center is 2.5 mm, the knife is retracted. After the lathe The end clamping device feeds and grabs the roller, the workpiece shaft continues to rotate, the roller and the bar form a relative rotation, the roller is twisted, the clamping device is retract...
