Description

Deep groove rough turning process

Technical Field

The invention relates to the technical field of deep groove machining, in particular to a deep groove rough turning machining process.

Background

Because the light-weighted theory of automobile parts is provided, many parts are indispensable for the design of weight-reducing deep groove, and the end face deep groove and the excircle deep groove are because the degree of depth of groove is long, the groove width is little, the grooving blade form is single when the turning, and the cutting of blade is to very big restriction. In addition, the scrap iron after cutting is not broken during machining, and the phenomenon that the pin is not smoothly arranged easily results in blade breakage and cutter body damage, so that the machining efficiency is low, and the use cost of the cutter is high.

Disclosure of Invention

The invention aims to provide a deep groove rough turning process which is easy to machine deep grooves, high in working efficiency and capable of prolonging the service life of a blade.

In order to achieve the purpose, the invention provides a deep groove rough turning process, wherein the travel path of the cutting tool for processing the deep groove is in a pulse-shaped structure and comprises depth direction cutting and transverse direction cutting which are perpendicular to each other.

Preferably, the deep groove to be processed is a deep groove having a groove width of 3 times or more.

Preferably, the width of the groove to be processed is larger than the width of the grooving blade.

Preferably, the path of the cutting blade is circularly performed after cutting feed in the depth direction is 0.4mm, and then the cutting blade is fed and moved in the transverse direction by 0.2mm, and then fed and moved in the depth direction by 0.4mm and moved in the transverse direction by-0.2 mm.

Preferably, the process is suitable for machining end face deep grooves and excircle deep grooves of carbon steel and alloy steel parts.

Therefore, the deep groove rough turning process is easy to machine deep grooves, high in working efficiency and capable of prolonging the service life of the blade.

The technical solution of the present invention is further described in detail by the accompanying drawings and embodiments.

Detailed Description

Embodiments of the present invention will be further described with reference to the accompanying drawings.

Fig. 1 is a schematic diagram of a feed path of a deep groove rough turning process, fig. 2 is a schematic diagram of a processing end surface groove in the deep groove rough turning process, fig. 3 is a schematic diagram of a processing outer circular groove in the deep groove rough turning process, and as shown in the figure, the deep groove rough turning process is suitable for processing end surface deep grooves and outer circular deep grooves of carbon steel and alloy steel parts, and the processed deep grooves are deep grooves with groove widths more than 3 times. The width of the processed groove is larger than that of the grooving blade, so that scrap iron which is cut off is discharged, and the cutter can turn a deep groove with the groove width more than 3 times.

The travel path of the cutting blade for processing the deep groove is in a pulse-shaped structure and comprises depth direction cutting and transverse direction cutting which are perpendicular to each other. The advancing route of the cutting knife is that after the cutting of the depth direction is fed for 0.4mm, the cutting knife is fed to the transverse direction again and moves for 0.2mm, and because the bottom edge of the cutting knife is not processed during the transverse feeding movement, the scrap iron can be cut off, the purpose is realized by the chip breaking processing function, and meanwhile, the processed groove width is larger than the width of the groove cutting blade, and the good discharging effect of the scrap iron is realized. Then, the depth direction feeding is moved by 0.4mm again, and the transverse movement is moved by-0.2 mm, and the circulation is carried out until the processing is carried out to the depth. Multiple times of processing verification proves that the processing technology can realize processing of the deep groove with the groove width of 3-8 times, the blade is not crushed by extrusion, and the technical problems of difficult processing and low efficiency of rough turning of the deep groove are solved.

The processing technology of the invention is explained according to the specific working process as follows:

as shown in figure 1, a cutting knife a cuts a workpiece b by a cutting belt with a serial number 1, scrap iron is cut off when the serial number 2 goes to 3, the groove width is enlarged to discharge the scrap iron, the serial numbers 3 to 4 are parts for cutting the workpiece, the scrap iron is cut off when the serial number 4 goes to 5, and the groove width is enlarged to discharge the scrap iron, namely, the vertical process is a scrap breaking process, and the horizontal process is a cutting process. The method can process to the required depth, and the cutting fluid can also enter the cutting part of the cutter to play a good cooling role. Because the cutter has a round angle, the cutting depth does not exceed the round angle of the cutter every time, so that the side surface of the cut groove does not have a deep groove, and the processing requirement can be met.

Finally, it should be noted that: the above embodiments are only for illustrating the technical solutions of the present invention and not for limiting the same, and although the present invention is described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that: modifications and equivalents may be made to the invention without departing from the spirit and scope of the invention.
