Machine head for cutting and processing irregular steel bar

Abstract

The invention discloses a machine head for cutting and processing an irregular steel bar. The machine head comprises a transmission case (7), wherein a transmission mechanism (71) is arranged inside the transmission case (7); cutter mounting bases (8), equal with the cutting faces of the irregular steel bar in number, are arranged on the transmission case (7); a cutting tool (12) capable of rotating around a center axis is mounted in each of the cutter mounting bases (8); the cutting tools (12) are distributed in a ring array manner; the tool noses of the cutting tools (12) are towards the inner side; included angles are formed by the rotating centers of the cutting tools (12) and the center points of the ring array of the cutting tools (12); the cutting tools (12) are driven by the transmission mechanism (7) to be rotated. The machine head disclosed by the invention can effectively improve the producing and processing efficiency of the irregular steel bar, and meanwhile reduce the producing and processing cost of the irregular steel bar.

Description

Technical field: [0001] The invention relates to the technical field of special-shaped rod processing equipment, and more specifically relates to a special-shaped rod chip processing machine head. Background technique: [0002] In the prior art, there are mainly two ways to process special-shaped rods (such as hexagonal rods, pentagonal rods, etc.), one of which is to use cold drawing or cold drawing, and the round rods are drawn by cold drawing or cold drawing. Processing into special-shaped rods requires multiple processes, such as removing cracks on the surface of round rods, pickling, annealing, etc., and then passing through a mold by drawing and extrusion molding to obtain special-shaped rods. The method needs to go through multiple processes, the production efficiency is low, and the production cost is relatively high, and the extrusion molding process will inevitably damage the internal crystal phase structure and affect the quality of the rod. Especially this proces...

[0002] In the prior art, there are mainly two ways to process special-shaped rods (such as hexagonal rods, pentagonal rods, etc.), one of which is to use cold drawing or cold drawing, and the round rods are drawn by cold drawing or cold drawing. Processing into special-shaped rods requires multiple processes, such as removing cracks on the surface of round rods, pickling, annealing, etc., and then passing through a mold by drawing and extrusion molding to obtain special-shaped rods. The method needs to go through multiple processes, the production efficiency is low, and the production cost is relatively high, and the extrusion molding process will inevitably damage the internal crystal phase structure and affect the quality of the rod. Especially this processing method needs to be mentioned There is also the disadvantage of limited use. When the hardness of the processed material is high, this method cannot achieve forming processing; another method is to process through CNC programming, and use CNC machining centers or CNC milling machines to process round bars. Each surface of the rod is processed. This method requires multiple clamping during the processing, which not only affects the processing accuracy of the rod, but also has very low production efficiency, which cannot meet the needs of mass production and processing at all.
