Abstract
The invention relates to an oil-groove extrusion screw tap, in particular to a spiral-oil-groove extrusion screw tap. The spiral-oil-groove extrusion screw tap comprises a screw tap body, and the front end of the screw tap body is a threaded tapping section. The spiral oil-groove extrusion screw tap is characterized in that a spiral oil groove is formed in the threaded tapping section. Since the spiral oil groove is formed in the threaded tapping section, in the tapping process, cooling liquid can be evenly and continuously stored and supplied to a cutting edge via the spiral oil groove along with spiral cutting processing of the screw tap, cooling and lubricating effects during processing are enhanced, and friction during processing is lowered. Meanwhile, when the screw tap with the spiral oil groove is working at a high rotating speed, due to action of centrifugal force, the cooling liquid can reach a processed part fully and quickly and wash and clean cutting immediately, the cuttings are prevented from accumulating and adhering to the cutting edge so as to form a built-up edge, precision of processed pieces is improved, surface roughness is lowered, and service life of the screw tap is prolonged by 1-1.5 times.
Description
Technical field
The present invention is a kind of oil-groove thread forming tap, particularly a kind of spiral oil groove thread forming tap.
Background technology
Existing straight channel type thread forming tap, as shown in Figure 1, it comprises screw tap main body 1, and screw tap main body 1 front end is thread tapping section 2, and thread tapping section 2 is provided with straight channel type oil groove 3.The screw tap of this structure, the effect of Cooling and Lubricator is not good enough, so the heat that produces when work is large, easy sizing, the screw tap blade easily collapses tooth, annealing, fracture.
Summary of the invention
The objective of the invention is easily to collapse for the not good enough easy sizing of effect that overcomes existing straight channel type screw tap Cooling and Lubricator the defective of tooth fracture, invent a kind of helical oil groove formula thread forming tap.
The objective of the invention is to realize as follows: described spiral oil groove thread forming tap, comprise the screw tap main body, the screw tap body front end is the thread tapping section, it is characterized in that: the thread tapping section is provided with spiral oil groove.
Good effect of the present invention is as follows: owing to be provided with spiral oil groove in the thread tapping section of screw tap, so in the screw tap course of work, cooling fluid along helical oil groove with the screw type machining of screw tap, can be evenly, continuously cooling fluid is stored and provides to cutting edge, strengthen the Cooling and Lubricator effect in the processing, reduced the friction in the processing.Simultaneously, with the screw tap of helical oil groove when High Rotation Speed is worked, because the effect of centrifugal force, cooling fluid can arrive working position fully, fast, and smear metal in time washed away cleaning, avoid smear metal to pile up being bonded on the cutting edge and form built-up-edge, thereby improve the precision of workpiece, reduce surface roughness, 1～1.5 times of the Service life of screw tap.
Description of drawings
Fig. 1 is existing straight channel type screw tap structure chart
Fig. 2 is helical oil groove thread forming tap structure chart
Among the figure: 1 screw tap main body, 2 thread tapping sections, 3 straight channel type oil grooves
4 spiral oil grooves.
The specific embodiment
As shown in Figure 2, described spiral oil groove thread forming tap comprises screw tap main body 1, and screw tap main body 1 front end is thread tapping section 2, it is characterized in that: thread tapping section 2 is provided with spiral oil groove 4.
Because the thread tapping section at screw tap is provided with spiral oil groove, so in the screw tap course of work, cooling fluid along helical oil groove with the screw type machining of screw tap, can be evenly, continuously cooling fluid is stored and provides to cutting edge, strengthen the Cooling and Lubricator effect in the processing, reduced the friction in the processing.Simultaneously, with the screw tap of helical oil groove when High Rotation Speed is worked, because the effect of centrifugal force, cooling fluid can arrive working position fully, fast, and smear metal in time washed away cleaning, avoid smear metal to pile up being bonded on the cutting edge and form built-up-edge, thereby improve the precision of workpiece, reduce surface roughness, 1～1.5 times of the Service life of screw tap.
Claims (1)
1. a spiral oil groove thread forming tap comprises the screw tap main body, and the screw tap body front end is the thread tapping section, it is characterized in that: the thread tapping section is provided with spiral oil groove.
