Abstract
The utility model provides a thread rolling plate for rolling non-round section screw arbor with screw edge-post shape, which is characterized in that the working surface of the utility model is provided with tooth lines which are utilized to produce the processed screws, and the surface of the tooth crest of the tooth line is designed to a plane surface; the tooth line on the plane surface is presented wave shape along the tooth line direction, the connecting line of the nadir of the tooth crest is parallelled to the bottom surface of the thread rolling plate and inclined to the arrangement surface of the thread rolling plate; thus, the utility model not only rolls screws of non-round section screw arbor with screw edge-post shape, but also provides a high efficiency manufacture tool for the screws processing.
Description
The utility model belongs to machinery tools, particularly a kind of screw plate of scroll column on-circular cross-section screw flight processing.
In the prior art, the method that productivity ratio is the highest in the Thread Machining Process is to twist screw thread with screw plate.Because the tooth line of this class screw plate is to distribute on a plane that is parallel to the screw plate bottom surface.Therefore its processing object is cylindric screw thread or straightedge column triangular-section screw thread, and the cross section of blank must be leg-of-mutton during the processing latter, then can't realize for the processing of scroll column on-circular cross-section screw thread.
The purpose of this utility model provides a kind of screw plate that is used to twist scroll column on-circular cross-section screw rod.
The technical solution of the utility model is to solve like this, this screw plate is made up of moving plate 1 and quiet plate 2, the tooth line 4 that is intended to form processed screw thread is arranged on working face 3, the face at its tooth line 4 crest peak places is planes, tooth line on the plane is along tooth line direction undulate, crest minimum point line 5 is parallel to the bottom surface 6 of screw plate, and tilts with the device surface 7 of screw plate.Have the structure that can have the cone, tapered thread or the incomplete thread that are intended to form processed screw rod end beyond the working face of tooth line.
Advantage of the present utility model is to utilize this screw plate, not only can process the on-circular cross-section screw flight, and main is provides the high efficiency tool of production for the processing of this screw thread.
Below in conjunction with accompanying drawing the utility model is illustrated.
Fig. 1 is a processing schematic diagram of the present utility model.
Fig. 2 is a moving screw die face structural representation of the present utility model.
Fig. 3 is the A-A partial enlarged drawing of Fig. 2.
Fig. 4 is the B-B partial enlarged drawing of Fig. 2.
According to shown in Figure 1, this screw plate is divided into moving plate 1 and quiet plate 2, and the tooth line structure of moving plate and quiet plate is identical, is combined by moving plate and each one of quiet plate during use.As shown in Figure 2, the tooth line 4 that is intended to form processed screw thread is arranged on working face 3, and the face at tool tooth line 4 crest peak places is planes, and the tooth line is along tooth line direction undulate, crest minimum point or peak line are parallel to the bottom surface of screw plate, and tilt with the device surface of screw plate.Have beyond the working face of tooth line the structure that needs by processing object can exist the cone, tapered thread or the incomplete thread that are intended to form processed screw rod end.When twisting scroll column on-circular cross-section screw with this screw plate, blank is a cylinder.Its using method is identical with existing screw plate.
Claims (2)
1, a kind of screw plate that twists the on-circular cross-section screw rod, form by moving plate 1 and quiet plate 2, it is characterized in that the tooth line 4 that is intended to form processed screw thread is arranged on working face 3, the face at its tooth line 4 crest peak places is planes, plane upper tooth line is along tooth line direction undulate, crest minimum point line 5 is parallel to the bottom surface 6 of screw plate, and tilts with the device surface 7 of screw plate.
2, the screw plate that twists the on-circular cross-section screw rod according to claim 1 is characterized in that: have the structure that can have the cone, tapered thread or the incomplete thread that are intended to form processed screw rod end beyond the working face of tooth line.
