Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the implementations. example. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

Please refer to FIGS. 1-4, an embodiment provided by the present invention: a screw mold, including a workbench 1, the bottom four corners of the workbench 1 are provided with support legs 2, and the middle position of the top of the workbench 1 A second groove 13 is provided at the place, the inner grinding pipe 4 of the workbench 1, and a pneumatic cylinder 7 (DA series stainless steel cylinder) is installed on both sides of the top of the workbench 1, and the output end of the pneumatic cylinder 7 passes through the mounting frame. 9. A positive and negative motor 8 (90YYTJ) is installed, and a fixed plate 3 is installed at the output end of the positive and negative motor 8. The interior of the fixed plate 3 is provided with a first groove 11, and the top of the first groove 11 is installed There is a magnet 10, an inner slide 15 of the workbench 1, and the top of the slide 15 is slidably connected to a collection bin 6 through a slide.

The utility model interacts with the grinding pipe 4 through the fixed plate 5, so that the grinding pipe 4 is disassembled and connected with the worktable 1, so that the grinding pipe 4 is easy to disassemble and replace, thereby improving the work efficiency. Under the action of the pneumatic cylinder 7, the screw is ground once, and then the positive and negative motor 8 drives the screw to rotate to realize the second grinding of the screw, thereby greatly improving the quality of the screw.

Please refer to FIG. 3 , the grinding pipe 4 is a hollow structure, and the inner wall of the grinding pipe 4 is evenly provided with internal threads 12 , and the material of the internal threads 12 is high carbon steel.

The high carbon steel inner thread 12 provided in the screw mold makes the inner thread 12 harder and more wear-resistant, thereby improving the service life of the grinding pipe 4 .

Please refer to FIGS. 1 and 3 , the outer side of the grinding tube 4 is provided with a fixed plate 5, and the number of the fixed plate 5 is four groups, and the four groups of the fixed plate 5 are distributed in a "cross" shape. The second groove 13 is matched, and the grinding tube 4 is slidably connected with the second groove 13 .

The four sets of "cross"-shaped fixing plates 5 provided in this screw mold enable the grinding pipe 4 to be easily disassembled from the workbench, and the grinding pipe 4 can be stably fixed inside the workbench 1, so that the grinding of the screw can be completed.

Please refer to FIG. 2 , the first groove 11 is hexagonal.

The hexagonal first groove 11 provided in the screw mold enables the fixing plate 3 to drive the screw, so as to prevent the screw from sliding inside the fixing plate 3 .

Working principle: First, turn on the power supply of the device, put the unformed screw head into the fixing plate 3, and fix the screw in the fixing plate 3 under the action of the magnet 10. At this time, the air cylinder 7 drives the positive The reverse motor 8 moves up and down, and at the same time, the positive and negative motor 8 drives the screw to rotate through the fixed plate 3, the rotating screw enters the grinding tube 4, and the rotating screw is polished by the internal thread 12, thereby making a grinding of the screw, Then start the positive and negative motor 8, so that the positive and negative motor 8 rotates in the reverse direction, so that the screw is separated from the grinding tube 4, and the second grinding of the screw is realized while the screw is separated from the grinding tube 4, so that the quality of the screw is greatly improved. The waste chips enter the collection bin 6. Under the action of the sliding block 14 and the sliding plate 15, the collection bin is opened to process the waste chips. After a long period of operation, the grinding pipe 4 can be taken out and replaced with a new grinding pipe 4 to avoid internal Excessive wear of the thread 12 affects the machining quality.
