Abstract

A screw thread rolling plate for producing screw with self-locking and high chip property is composed of main thread rolling plate and auxiliary thread rolling plate. The main dental plate and the auxiliary dental plate are provided with a tooth rubbing part and a chip removing part. The thread rolling part comprises thread rolling grooves and thread rolling edges. The main dental plate and the auxiliary dental plate are provided with a converging part, a shaping part, a first double-tooth groove and a second double-tooth groove. The first double socket includes a first socket, and a first plane. The second double socket includes a second socket, and a second plane. The first double socket is provided in the converging portion and the shaping portion. And setting the depth of the first tooth groove to be smaller than the depth of the thread rolling groove, and forming a self-tapping part surface for assisting cutting so as to increase the cutting performance of the screw. The depth of the second tooth groove is the same as that of the tooth twisting groove, and the self-locking part is formed on the screw tooth to increase friction force with wood, so that self-locking property of the screw is improved.

Description

Thread rolling plate for producing screw with self-locking and high chip property Technical Field The utility model relates to the technical field of die dies, in particular to a die plate for producing a screw with self-locking and high chip property. Background The die plate die is used for forming two rectangular templates on the die rolling machine, one is a main die plate, the die plate die is fixedly arranged on the structure, the other is an auxiliary die plate, the die plate die is arranged on the horizontal driving mechanism, threads are arranged on the main die plate and the auxiliary die plate, a bolt is placed between the main die plate and the auxiliary die plate, the auxiliary die plate is driven to transversely move, and the bolt is forced to be extruded and roll between the main die plate and the auxiliary die plate, namely, the screw teeth on the outer wall of the bolt are completed. However, when the existing screw threads attack wood, the cutting performance of the screw is poor, the screw cannot be quickly screwed into the wood, and the problem of poor self-locking performance of a single screw thread also exists. There are also ways to add additional threads to the threads to increase the cutting performance of the screw. However, the existing equipment can only form one screw thread in sequence, if different types of screw threads are required to be added, the screw threads are required to be processed independently, and the defective rate is high. Disclosure of utility model In view of the above, the present utility model provides a method for producing a screw thread rolling plate with self-locking and high chip property, so as to solve the above technical problems. A tooth-rubbing plate for producing screw with self-locking and high chip property is composed of a main tooth plate, an auxiliary tooth plate, a tooth-rubbing part on the opposite end surfaces of said main tooth plate and auxiliary tooth plate, and a chip removing part obliquely arranged on one side of the length of said main tooth plate and auxiliary tooth plate. The thread rolling part comprises a plurality of thread rolling grooves obliquely arranged on the converging part and the shaping part, and a plurality of thread rolling ridges arranged between every two thread rolling grooves.
