[0002] With the development of manufacturing technology and the progress of the times, the application of screws is very common, and screws are one of the common connectors in our daily life. At the same time, a thread rolling machine is often needed in the processing of screws. A thread rolling machine is a processing equipment for the outer surface of a cylindrical workpiece. It is two identical thread rolling surfaces with the same thread shape and helix angle as the bolt thread. When the thread rolling plates move against each other, the bolt blank between the two thread rolling plates is threaded. One bolt thread is processed once the thread rolling plates go back and forth.

[0003] The existing thread rolling machine for processing screws occasionally needs to perform thread rolling operations on both ends of some special screws during use. After thread rolling on one end, the entire screw is heated and difficult to pick up and adjust, which reduces the working efficiency of the thread rolling machine. Utility Model Content

[0008] Preferably, an inspection door is installed on the other side below the front of the machine body.

[0009] Preferably, a reserved groove is provided on one side of the top end of the second rubbing tooth plate.

[0010] Preferably, the second rubbing plate forms a sliding structure through a slider, a slide groove and a body, and the second rubbing plate forms a transmission structure through a connecting frame, a connecting shaft, a connecting rod and a power disc.

[0011] Preferably, the connecting rod is connected to the power disc via a shaft, and the length of the shaft is greater than half of the width of the second rubbing plate.

[0012] Preferably, the clamping seat and the first rubbing plate are on the same horizontal line, and the clamping seat forms a detachable structure through the threaded tube and the rotating shaft.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0014] 1. In the utility model, the thread rolling machine is started by setting the thread rolling plate, the clamping seat and the machine body, so that the power disk rotates, thereby driving the connecting rod to move, and the second thread rolling plate is driven to perform a transmission operation, so that the second thread rolling plate performs a thread rolling operation on the screws placed on the first thread rolling plate. At this time, the screw generates heat due to thread rolling, so it is necessary to reverse the direction and continue the thread rolling process. The motor can drive the rotating shaft to rotate, so the clamping seat above it rotates the clamped screw, so that the thread rolling machine can perform a thread rolling process on the other end of the screw, thereby improving the work efficiency of screw processing.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Reference Figure 1-3 A thread rolling machine for processing screws, including a machine body 1, a first thread rolling plate 2 is installed on the upper inner side of the machine body 1, and a slide groove 7 is opened on the inner wall of the machine body 1, a slider 9 is slidably connected to the inner side of the slide groove 7, and a second thread rolling plate 3 is fixed to the front of the slider 9, a connecting frame 4 is welded to the top of the second thread rolling plate 3, and a connecting rod 5 is installed on the inner side of the connecting frame 4, the connecting rod 5 is connected to the connecting frame 4 through a connecting shaft 14, and the other end of the connecting rod 5 is connected to a power disk 6, the connecting rod 5 is connected to the power disk 6 through a shaft body, and the length of the shaft body is greater than half of the width of the second thread rolling plate 3. By setting the length of the shaft body greater than half of the width of the second thread rolling plate 3, the second thread rolling plate 3 is pulled by the connecting rod 5 and moves back and forth. There will be no contact or collision with the power disk 6. A fixed box 8 is installed on one side of the lower front of the machine body 1, and a motor 10 is installed inside the fixed box 8. The output end of the motor 10 is connected to a rotating shaft 11, and the top of the rotating shaft 11 is threadedly connected to a threaded tube 12. A clamping seat 13 is installed on the top of the threaded tube 12. The clamping seat 13 and the first rolling plate 2 are on the same horizontal line, and the clamping seat 13 and the rotating shaft 11 form a detachable structure through the threaded tube 12. The middle part of the screw is clamped by the clamping seat 13, but the screw can still rotate under the action of external force, so that the motor 10 drives the rotating shaft 11 to rotate, and the clamping seat 13 above it drives the screw to change direction, which is convenient for assisting the thread rolling work at the other end of the screw.

[0022] An inspection door 15 is installed on the other side of the lower front of the body 1. The arrangement of the inspection door 15 makes it convenient for people to perform maintenance work on the internal components of the body 1. A reserved groove 16 is provided on one side of the top of the second threading plate 3. By setting the reserved groove 16, it can reserve space for the connecting rod 5 to rotate, and it is not easy to have the problem of movement interference between the second threading plate 3 and the connecting rod 5. The second threading plate 3 forms a sliding structure with the body 1 through the slider 9 and the slide groove 7, and the second threading plate 3 forms a transmission structure with the connecting frame 4, the connecting shaft 14, the connecting rod 5 and the power disk 6. The power disk 6 drives the connecting rod 5 to perform circular motion, and the other end of the connecting rod 5 is connected to the connecting frame 4 through the connecting shaft 14, so that the second threading plate 3 can be pushed to move back and forth, which is convenient for completing the thread rolling work of the screw processing.

[0023] Working principle: When in use, the staff first places the middle part of the screw that needs special processing on the clamping seat 13, and clamps it through the clamping seat 13. At the same time, one end of the screw is on the first thread rolling plate 2. Then, the thread rolling machine is started, so that the power disk 6 rotates under the driving action of the motor, thereby driving the connecting rod 5 to move, and the second thread rolling plate 3 is transmitted, so that the second thread rolling plate 3 performs a thread rolling operation on the screw placed on the first thread rolling plate 2. After completing the thread rolling work on one end of the screw, the screw at this time generates heat due to thread rolling, so it needs to be reversed and the thread rolling process is continued. The motor 10 can drive the rotating shaft 11 to rotate, so the clamping seat 13 above it rotates the clamped screw, so that the thread rolling machine can perform thread rolling on the other end of the screw, and the work of the thread rolling machine for processing screws is completed in this way.
