Abstract

The utility model relates to a machining tool in machining, in particular to a forming cutter comprising a cylindrical cutter handle taking an axis as a rotation axis, and a cutting part. The cutting part is arranged at one end of the cutter handle, and comprises a plurality of spiral screw blades which are arranged at the periphery of the end part of the cutter handle in ring-shaped manner; a spiral chip removal groove is formed between every two adjacent screw blades; the screw blade comprises a section of arc blade taking the axis as the starting end, and a concave blade part mutually connected with the terminal part of the arc blade; the terminal of the concave blade part is provided with a cone-shaped body with gradually enlarged diameter; the screw blade extends to the maximum-diameter position of the cone-shaped body, and forms an angle of 60 degrees between the screw blades; and the forming cutter can conduct one-step molding on the parts of the product needing to be machined, and can keep the consistency of the size of the product.

Description

The moulding cutter
Technical field
The utility model relates to the process tool in a kind of machining, is specifically related to a kind of moulding cutter.
Background technology
At processing work, need carry out fillet to the workpiece that processes or carry out chamfering, usually need carry out secondary or repeatedly processing to workpiece, thereby need change different cutters, processing often, complex procedures and clamping cutter trouble, such processing was both lost time, and operating efficiency is low again, and the smear metal that cutter produces when milling stops difficult the eliminating owing to be subjected to the cutter shaft end face, be entangled with easily, even paste on cutter hub because of high temperature, and the smear metal of pasting on cutter hub makes the surface of processing work produce scratch easily, can't make finished surface level and smooth.
The utility model content
At the problems referred to above, the purpose of this utility model provides a kind of workpiece fillet moulding cutter of finishing simultaneously in process.
The moulding cutter, comprise with the axis being cylindric handle of a knife, the cutting portion of rotating shaft, described cutting portion is arranged on an end of handle of a knife, described cutting portion comprises the multiple tracks helical edges of shape annular array around in the handle of a knife end in the shape of a spiral, form spiral helicine chip area between the per two adjacent helical edges, described helical edges comprises with the axis being one section circular arc sword at top, the recessed blade that is connected with circular arc sword terminal part, described recessed blade terminal is provided with diameter and increases bullet gradually, and described helical edges extends to bullet maximum gauge place.
Form angle α between the described helical edges, and the size of angle α is 60 °, guaranteed that cutter can carry out milling to workpiece smoothly, also guaranteed that the bits that mill out can discharge smoothly simultaneously from chip area.
Described recessed blade is the circular shape with radius, and the radius of described recessed blade is set as required.
Described handle of a knife and cutting portion are combined to form the T word shape.
Described handle of a knife adopts the mode of welding to be connected with cutting portion.
Adopt such scheme, the utility model is when the milling workpiece, finished the processing of workpiece fillet simultaneously, make the position one-shot forming that needs processing work, processing only needs use one can guarantee cutter the uniformity of workpiece to be machined size, simultaneously add the damage that man-hour workpiece is caused once more, thereby reduce production costs because thereby the utility model can one-shot forming have reduced.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
In the accompanying drawing, 1 is handle of a knife, and 2 is helical edges, and 3 is chip area, and 4 is the circular arc sword, and 5 is bullet, and 6 is recessed blade.
The specific embodiment
Referring to shown in Figure 1, the moulding cutter comprises with the axis being cylindric handle of a knife 1, the cutting portion of rotating shaft, described cutting portion is arranged on an end of handle of a knife 1, described cutting portion comprises the multiple tracks helical edges 2 of shape annular array around in handle of a knife 1 end in the shape of a spiral, form spiral helicine chip area 3 between the per two adjacent helical edges 2, described helical edges 2 comprises with the axis being one section circular arc sword 4 at top, the recessed blade 6 that is connected with circular arc sword 4 terminal parts, described recessed blade 6 terminals are provided with diameter and increase bullet 5 gradually, and described helical edges 2 extends to bullet 5 maximum gauge places.Form angle α between the described helical edges 2, the size of angle α is 60 °.Described recessed blade 6 is for having the circular shape of radius.Described handle of a knife 1 is combined to form the T word shape with cutting portion.Described handle of a knife 1 adopts the mode of welding to be connected with cutting portion.
When using the utility model, with the clamping part of cutter clamping at the milling machine cutter, starting the milling machine motor rotates cutter, described circular arc sword 4 is processed with the workpiece to be machined surface, 6 pairs of workpiece that process of the recessed blade of cutter carry out fillet, once finish the processing to workpiece to be machined, owing to have 60 ° angle between the helical edges 2, the bits that milling is come out are discharged from chip area 3 easily.
