Abstract
The utility model relates to a thread roller, which comprises a roller, a mandrel, a cutter and a spring box. The mandrel penetrating through two ends of the cutter is fixed by a nut, the roller is mounted on the mandrel, a bearing is arranged between the roller and the mandrel, positioning sleeves are respectively arranged among the upper end and the lower end of the bearing and the cutter, the roller is positioned on the cutter via the position sleeves, the tail end of the cutter is connected with the spring box via a bolt, the cross section of the roller is in a toothed structure, one side of the cross section of the roller includes two mutually symmetric toothed heads, and the shape of a portion between the two toothed heads is consistent with the tooth shape of threads. The thread roller press has the advantages of reasonable structural design, convenience in operation, even force born by the tooth shape of the rolled threads, and effective improvement of precision of thread sizes and quality of thread finished products.
Description
Technical field
The utility model relates to a kind of screwing tool, particularly a kind of rolling screw-threads device.
Background technology
At present, in mechanical processing industry, generally adopt rolling screw-threads device machining screw, rolling screw-threads device roller is substantially all according to the thread groove design, and the head of roller adopts the single head design.In the machining screw process, the position of roller roll extrusion is the groove of screw thread, if in the roll extrusion process, in case unbalance stress takes place, will cause the shape generation deviation of form of thread, thereby influence the quality and the precision of screw thread finished product.
Summary of the invention
The utility model has overcome deficiency of the prior art, and a kind of reasonable in design is provided, rolling screw-threads device easy to use.
In order to address the above problem, the utility model by the following technical solutions:
The rolling screw-threads device, comprise roller, mandrel, cutter hub and spring case, mandrel passes the cutter hub two ends and fixes by nut, roller is installed on the mandrel, be provided with bearing between roller and the mandrel, be respectively equipped with positioning sleeve between two ends and the cutter hub about the bearing, roller is positioned on the cutter hub by positioning sleeve, the cutter hub end is connected with spring case by bolt, the roller cross section is the thread form structure, one side of roller cross section comprises two symmetrical tooth heads, and the shape of part is consistent with form of thread between the two tooth heads.
Be provided with disk spring in the described spring case.
Compared with prior art, the beneficial effects of the utility model are:
Roller of the present utility model cross section is designed to profile of tooth according to the tooth form of screw thread, in the roll extrusion process, the phenomenon of the form of thread unbalance stress that twice roll extrusion cause is avoided in each tooth form one-shot forming of screw thread, effectively raises the dimensional accuracy of screw thread and the quality of screw thread finished product.
Description of drawings
Fig. 1 looks cutaway view for the utility model master;
Fig. 2 is the utility model left view.
The specific embodiment
The rolling screw-threads device, as shown in Figure 1 and Figure 2, comprise roller 1, mandrel 3, cutter hub 6 and spring case 7, mandrel 3 passes cutter hub 6 two ends and fixing by nut 4, and roller 1 is installed on the mandrel 3, is provided with bearing 2 between roller 1 and the mandrel 3, bearing is respectively equipped with positioning sleeve 5 between two ends and the cutter hub 6 about in the of 2, roller 1 is positioned on the cutter hub 6 by positioning sleeve 5, and cutter hub 6 ends are connected with spring case 7 by bolt 9, are provided with disk spring 8 in the spring case 7.Roller 1 cross section is the thread form structure, and a side of roller 1 cross section comprises two symmetrical tooth heads, and the shape of part is consistent with form of thread between the two tooth heads, and the angle R of tooth head dual-side is consistent with the tooth form angle of screw thread.
During machining screw, the utility model cutter hub 6 rotates in spring case 7, and cutter hub 6 drives roller 1 action, thereby surface of the work is rolled out screw thread.
