Abstract
The invention relates to a scrap-containing-inclined-grain thread rolling wheel with a guide corner. The wheel comprises a thread rolling wheel body (1). At least two tooth grains (4) are arranged on the outer surface of the thread rolling wheel body (1), each tooth grain (4) is arranged in the axial direction perpendicular to a central hole (2), each tooth grain (4) is divided into a tooth top (5) and a tooth root (6), and a scrap containing groove (7) is formed in the bottom of the tooth root (6). The guide angle alpha is formed between straight lines of the plurality of tooth tops (5) and the plurality of tooth roots (6). The tooth depth of the scrap-containing-inclined-grain thread rolling wheel becomes larger gradually, and the certain guide angle is formed, so that a rolled screw is high in strength, good in quality and not easy to break. Due to the fact that the scrap containing grooves are formed in the bottoms of the tooth roots, surplus scraps produced in a machining process can be collected, and bolt quality is ensured.
Description
(1) technical field
The present invention relates to a kind of cylindrical die roll, relate in particular to a kind of appearance bits twill cylindrical die roll that contains guide angle.
(2) background technology
Cylindrical die roll is on screw-rolling machine, to utilize the method for metal plastic deformation to roll out a kind of instrument of screw thread, is applicable to process high-strength bolt.The depth of threat of cylindrical die roll is consistent at present, and crest is identical to the degree of depth of root of the tooth, and so the intensity of nip drum screw rod out is not high, easily fracture; In the process of bolt, can produce unnecessary scrap on cylindrical die roll, affected to a certain extent the processing effect of bolt, the bolt poor quality who produces.
(3) summary of the invention
The object of the invention is to overcome above-mentioned deficiency, a kind of appearance that contains guide angle bits twill cylindrical die roll that has guide angle, depth of threat to become gradually large and can collect unnecessary scrap is provided.
The object of the present invention is achieved like this:
A kind of appearance bits twill cylindrical die roll that contains guide angle, comprise cylindrical die roll body and centre bore, described centre bore edge is provided with keyway, the cross section of described cylindrical die roll body is annular, the outer surface of described cylindrical die roll body is provided with the tooth line, described tooth line has two at least, described each tooth line is twill, described each tooth line is arranged along the axial direction perpendicular to centre bore, described each tooth line is divided into crest and root of the tooth, the bottom of described root of the tooth is provided with chip pocket, between the straight line at described a plurality of crests and a plurality of roots of the tooth place, has guide angle α.
The appearance bits twill cylindrical die roll that the present invention contains guide angle, the material of described cylindrical die roll body adopts medium carbon steel.
Compared with prior art, the invention has the beneficial effects as follows:
The depth of threat of appearance that the present invention contains guide angle bits twill cylindrical die roll becomes greatly gradually, and certain guide angle is arranged, and makes the intensity of nip drum screw rod out high, quality good, is not easy to rupture; The bottom of root of the tooth is provided with the scrap groove, can be collected in the unnecessary scrap produced in the process of processing, has guaranteed the quality of bolt.
(4) accompanying drawing explanation
The vertical section structure schematic diagram that Fig. 1 is the present invention's appearance bits twill cylindrical die roll of containing guide angle.
The cross section cutaway view that Fig. 2 is the present invention's appearance bits twill cylindrical die roll of containing guide angle.
The structural representation that Fig. 3 is screw thread.
Wherein:
Cylindrical die roll body 1
Centre bore 2
Keyway 3
Tooth line 4
Crest 5
Root of the tooth 6
(5) specific embodiment
Referring to Fig. 1～Fig. 3, the appearance bits twill cylindrical die roll that the present invention contains guide angle, comprise cylindrical die roll body 1 and centre bore 2, described centre bore 2 edges are provided with keyway 3, the material of described cylindrical die roll body 1 adopts medium carbon steel, the cross section of described cylindrical die roll body 1 is annular, the outer surface of described cylindrical die roll body 1 is provided with tooth line 4, described tooth line 4 has two at least, described tooth line 4 is twill, described each tooth line 4 is arranged along the axial direction perpendicular to centre bore 2, described each tooth line 4 is divided into crest 5 and root of the tooth 6, the bottom of described root of the tooth 6 is provided with chip pocket 7, there is guide angle α between the straight line at described a plurality of crest 5 and a plurality of root of the tooth 6 places.
The depth of threat of appearance that the present invention contains guide angle bits twill cylindrical die roll becomes greatly gradually, and certain guide angle is arranged, and makes the intensity of nip drum screw rod out high, quality good, is not easy to rupture; Be provided with chip pocket 7 in the bottom of root of the tooth 6, can be collected in the bolt process the unnecessary scrap produced, guaranteed the quality of bolt.
Claims (2)
1. an appearance that contains guide angle is considered the twill cylindrical die roll to be worth doing, comprise cylindrical die roll body (1) and centre bore (2), described centre bore (2) edge is provided with keyway (3), the cross section of described cylindrical die roll body (1) is annular, the outer surface of described cylindrical die roll body (1) is provided with tooth line (4), described tooth line (4) has two at least, described each tooth line (4) is twill, described each tooth line (4) is arranged along the axial direction perpendicular to centre bore (2), described each tooth line (4) is divided into crest (5) and root of the tooth (6), it is characterized in that: the bottom of described root of the tooth (6) is provided with chip pocket (7), there is guide angle α between the straight line at described a plurality of crest (5) and a plurality of root of the tooth (6) place.
2. a kind of appearance bits twill cylindrical die roll that contains guide angle according to claim 1, is characterized in that: the material employing medium carbon steel of described cylindrical die roll body (1).
