However, the production of the existing special screw with groove and net furniture is firstly forged into the required product size by the A forging machine, and then processed by lathe: : groove and R angle at both ends Partly, that is to say, the production-supporting screw has to go through multiple processes in the original processing method. In the turning process, a large amount of iron is inevitably produced, which not only has a large consumption, but also has a long production cycle, complicated process, low work efficiency and high production cost. Disadvantages.发明, [Description of the Invention] 4 The object of the present invention is to provide a processing method for a plastic universal wheel which is simple in processing, saves raw materials, and reduces cost by shortening the production cycle and improving production efficiency. $ 凹本本5 is realized by the following transfer, the special screw of the flap universal wheel is made up of the right-hand groove and the inverted hook-shaped shaft body structure = the search screw is made up of π special: === shout = line and punched out ί ^ The heart method reduces the outer diameter of the screw to form the bottom of the groove and the ruler in the other. The use of the method to increase the outer diameter of the screw, and the hole, the shape of the mold in the mold is in the end of the embryo. Use _ 峨 the above sleeve shape, because Mei: 2 200911411 t to make the sleeve shape is squeezed by the mold when preparing for the surrounding, the final end with R, : ^ clothing-shaped bumps, for the end of the forming barb The oblique die and (4) the above-mentioned fresh barb, and the invention is characterized in that a standard barb is formed without modifying the bump. On the basis of this, by changing the production and use life, you can complete the whole two:: rod reduction, shorten production: == 21, [implementation] As shown in Figure 2 to Figure 6: plastic processing method Schematic, the special screw structure with the groove ^ hook and its method is: the first step, take the same 箄 先 〗, the shape of the shaft body, its processing and expansion method to reduce or increase the wire diameter , forging 20, 21 reduction method ^ - end with a reduction method to make the screw outside:; two embryos. The other end uses the expansion method to make the outer diameter of the screw and the bottom diameter of the groove 8, and the bottom diameter of the groove 10 is formed by the mold in the mold 23, w ^, and the sleeve shape is extruded by the extrusion method. Because, the other end is ready to use for forming the barbs 15. In the fourth step, the end bump 13' is formed into a standard barb 14, and the other end is formed by a die 26 having a slope angle. Pass = nuclear punch 30 extrusion 曰 = make the special screw of the plastic universal wheel in the ^ ^ force two method, the hair is completed, and the production efficiency can be increased several times. , A / / through a cold forging process 6 200911411 [Simplified description of the drawings] The present invention will be described below with reference to the accompanying drawings.
