New description: [New technical field] This creation is about a hollow drill bit structure that reduces manufacturing costs, and is especially suitable for manual, electric punching machines or similar structures used for drilling paper documents. By. [Prior Art] • The most common way to bind a paper document into a booklet is to use a puncher to punch the hole on the top edge of the paper or through the hole to pass the clamp or simply, and the puncher uses The middle (four) head A is made by the method of making a paste. First, it is necessary to cut a straight tube A1. The rear end of the straight tube A1 is a lock ring sleeve A2, and the chuck clip of the power punching machine is transmitted through the lock ring sleeve μ. Tight locking 'The shape of the lock ring 车 2 is quite time-consuming and labor-intensive. It is necessary to fit the reamer with the reamer to make a tapered taper hole 8.3, and at the same time grind the nozzle into a tapered drill hole Α4. _ _ above | Xiao's hollow drill bit structure, because turning is difficult to affect the production efficiency, while the cutting material is also a waste, and the tapered cone extends from the nozzle to the other diameter of the outlet because of the long distance 'not only reaming It is difficult to make sure that it is clear from the center, or that the hole is reamed from both ends to form a penetrating taper hole, which also makes the drum cutting time-consuming and increases the difficulty of construction, which is not ideal. In view of the lack of improvement of the traditional hollow drill bit, the creator can provide a hollow _ structure that is greatly reduced in laying down. It is a research and design system, and X provides / Xiao Fei to use it. The creative motive. [New Content] The main purpose of the structure of this creation is to provide the hollow bit structure of the low manufacturing cost: the purpose of the invention is to provide a hollow drill bit with a sharp drill hole. The structure of the hollow drill bit is formed by the dry agent and the gold, which is obtained by injection molding, and is defoamed, sintered and post-treated by decompression, and the production of 2 contains a lock. The other end has a tube _ towel hollow, lock ring The outer edge of the sleeve has a holding. The outer diameter and inner diameter of the p' body are straight tubular, while the inner diameter nozzle is provided with a tapered taper to form a sharp cut. As described above for the hollow drill bit structure, the tapered cone σ is increased upward from the nozzle when taper. The outstanding advantages of the present invention over the prior art are: Forming through the mold body, effectively simplifying the difficult and time-consuming manufacturing process of conventional hollow drill turning. 2, borrowing - body into the dragon ϋ ϋ 巾 towel empty network structure ' can effectively reduce manufacturing costs. 3 The inclined end of the inner control end of the raft is provided with a tapered taper hole to further form a sharp tapered drill hole. [Embodiment] The present invention will be further described in the following specific embodiments: Referring to the second and third figures, the manufacturing process of the hollow drill bit structure 1 of the present invention is as follows: Step a, mixing the adhesive with the metal powder; Step b, The above mixed product is injection molded in the mold; step c, further decompressed, degreased and sintered; and step d, post treatment. The hollow drill bit structure 1 is a mixing and mixing product mixed with a dry powder and a metal powder, and is injection molded in a mold and is subjected to pressure reduction, degreasing, sintering and post-treatment, thereby obtaining a 7-end lock ring sleeve 11 ' The end of the tube with the body 12 hollow drill job! The inner perforations 13 of the hollow drilled structure 1 have the same diameter, and the nozzle of the tubular body 12 is set as a tapered taper 14, as shown in the fourth figure. ... and 'Please refer to the fifth figure 'The hollow drill bit structure of this creation】 and the motor of the electric puncher, and the σ & π hollow drill bit structure 1 is moved up and down by the motor to be placed in the towel The bit structure of the drill bit is set to a perforation at the place where the paper 3 is placed by the inclined cone of the pipe of the pipe. The above is only the preferred embodiment of the present invention, and is not intended to limit the scope of the present creation. Anyone skilled in the art will be able to use the technique disclosed above. Shop _ rewriting, retouching, or any equivalent design changes made by the scope of the patent application for this creation shall be covered by the technology of this case.
