Abstract

The utility model relates to processing cutters in mechanical processing, in particular to a four-blade forming cutter, which comprises a cylindrical cutter handle, an end blade and four spiral blades. The cylindrical cutter handle uses the axis as a rotating shaft, the end blade is arranged at the end of the cutter handle, the spiral blades are arrayed on the periphery of the end of the cutter handle in a spiral annular shape, a scrap discharge groove is formed between each adjacent spiral blades, the end blade includes a first cutter blade with the axis as a starting end, a second cutter blade is arranged at a finish end of the first cutter blade, a finish end of the second cutter blade is connected with the spiral blades, and included angles alpha are formed among the spiral blade. Since the four-blade forming cutter is capable of forming once, thereby reducing damage on a workpiece in secondary processing and reducing production cost.

Description

Four sword moulding cuttves

Technical field

The utility model relates to the process tool in a kind of machining, is specifically related to a kind of four sword moulding cuttves.

Background technology

In the machining, need carry out fillet to the workpiece that processes or carry out chamfering, usually need carry out secondary or repeatedly processing to processing work, the angle that needs tool changing or adjustment cutter, processing often, the operation more complicated, and the clamping cutter is cumbersome, and such processing was both lost time, and operating efficiency is low again, the smear metal that cutter produces when milling stops that smear metal is difficult for getting rid of in working angles owing to be subjected to the cutter shaft end face, and smear metal is entangled with easily, be not easy smooth eliminating, 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 four sword moulding cuttves of finishing the workpiece fillet simultaneously and be convenient to chip removal in process.

Four sword moulding cuttves, comprise with the axis being the cylindric handle of a knife of rotating shaft rotation, the end sword that is arranged on the handle of a knife end, the four roads helical edges of shape annular array around in the shape of a spiral in the handle of a knife end, form a chip removal groove between the per two adjacent helical edges, described end sword comprises with described axis being first blade at top, the first blade terminal is provided with second blade, the terminal of second blade is connected with described helical edges, forms angle α between the described helical edges.

Further, described first blade is one section straight cutting edge, and milling is carried out on the surface of workpiece, and described second blade is the circular arc sword, and workpiece is carried out chamfering or fillet, and an end of circular arc sword is connected with first cutting edge, the other end is connected with helical edges.

Angle α between the described helical edges is 60 °, can guarantee to discharge from the chip removal groove smoothly by the bits that this cutter milling is got off.

Adopt such scheme, the utility model is when the milling workpiece, described second blade has been finished the processing of workpiece fillet simultaneously, make the position one-shot forming that needs processing work, can guarantee simultaneously the uniformity of workpiece to be machined size, improved production efficiency, because the angle that has 60 ° between the circular arc sword of the present utility model, the bits that cutter produces in milling process can be discharged from the chip removal groove easily, 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 are the chip removal groove, and 4 is first blade, and 5 is second blade.

The specific embodiment

Referring to shown in Figure 1, four sword moulding cuttves, comprise with the axis being the cylindric handle of a knife 1 of rotating shaft rotation, the end sword that is arranged on handle of a knife 1 end, the four roads helical edges 2 of shape annular array around in the shape of a spiral in handle of a knife 1 end, form a chip removal groove 3 between the per two adjacent helical edges 2, described end sword comprises with described axis being first blade 4 at top, the terminal that first blade, 4 terminals are provided with second blade, 5, the second blades 5 is connected with described helical edges 2, forms angle α between the described helical edges 2.Described first blade 4 is one section straight cutting edge, and described straight cutting edge is that cross section is circular cutting edge, and described second blade 5 is the circular arc sword, and an end of circular arc sword is connected with first cutting edge 4, the other end is connected with helical edges 2.Angle α between the described helical edges 2 is 60 °.

When using the utility model, with the retained part of the utility model handle of a knife 1 clamping at milling machine, start the milling machine motor, the knife end sword begins to contact with workpiece to be machined, workpiece is carried out milling work, described circular arc sword is finished fillet in process, owing to have 60 ° of angles between the helical edges 2, the bits that milling is come out are discharged from the chip removal groove easily.

Claims
