Description
Technical Field
The utility model relates to a device for rolling triangular threads, in particular to a triangular thread rolling device which can improve the surface smoothness of threads and obtain a root arc which cannot be obtained by processing a forming cutter, can meet special rolling requirements on the threads and can improve the product quality.
Background
In the pull rod product, standard 60-degree triangle threads are formed at two ends of the pull rod, a standard thread cutter is adopted for processing and forming, but partial threads are nonstandard 60-degree triangle threads, the standard 60-degree triangle threads are the same, special requirements on the smoothness of the threads and the thread root fillets are met, even clients definitely require rolling the threads, under the premise that the conventional cutter cannot meet the requirements, the surface smoothness of the threads can be improved to meet the arc requirements of the thread root through a rolling device for manufacturing the triangle threads, and the special requirements of the clients on the rolling of the threads can be met.
Disclosure of utility model
The utility model aims to overcome the defects in the prior art and provide the triangular thread rolling device which not only can improve the surface finish of the thread after the thread is processed, but also can obtain the root fillet which cannot be processed by a forming cutter, thereby meeting the special requirements of customers on thread rolling.
The technical scheme of the utility model is realized as follows: a triangular thread rolling device comprises a tool rest with a groove at the head, a rolling tool is arranged in the groove of the tool rest, mandrel mounting holes are formed in the tool rest at two sides of the groove, and a mandrel is arranged in the mandrel mounting holes; the bearing mounting holes are formed in the two inner sides of the rolling cutter, two bearings are mounted in the bearing mounting holes in the two inner sides of the rolling cutter, a sleeve is mounted between the two bearings, a mandrel penetrates through the sleeve, one end of the mandrel is provided with threads, the other end of the mandrel is provided with a step head, the mandrel with threads penetrates through one side of the tool rest and then is connected with a nut on the other side of the tool rest, the mandrel mounting holes are step holes, the step heads of the nut and the other end of the mandrel are located in the step holes, and the rolling cutter, the bearings and the sleeve are mounted on the tool rest through connection of the mandrel and the nut.
And selecting a proper rolling cutter according to the arc size of the processed triangular thread root so as to meet the requirements of customer drawings on the tooth shape.
The technical scheme of the utility model has the following positive effects: the surface finish of the thread can be improved, and the requirement of customer drawings can be met after rolling.
