Definitions

• the invention relates to the field of shredder tools, in particular to an integrated shredder tool processing technology. Background technique
• the shredder mainly uses a shredder blade that is fixed in groups on two parallel and relatively rotating cutter shafts. When the two cutter shafts rotate simultaneously, the waste paper is squeezed, thereby utilizing the shredder blades on the cutter shaft. The waste paper is cut into fine paper strips or granules, so the quality of the shredder tool (consisting of the knife shaft and the shredder blade) and the improvement of the manufacturing method are particularly important.
• the traditional shredder tool processing method (that is, a method in which a plurality of shredder blades are fixed in series to the cutter shaft to form a shredder cutter) has the following methods: The shredder cutter is processed at intervals of intervals, and the cutting process is used. A shredder tool with integrated root bar processing, using an internal ball expansion method to manufacture an integrated shredder tool.
• the shredder blade is fixed on the cutter shaft by using a spacer to prepare a shredder cutter
• the shredder cutter processed by the method comprises a cutter shaft, a plurality of blades and a spacer, and the blade is fixed by the adjacent spacer
• the shredder tool processing method is simple and easy to operate, but the cost of the shredder tool is correspondingly increased due to the increase of the spacing ;; on the other hand, the force received by the spacer is limited.
• the shredder cutter cuts the waste paper, it may cause cracking of the shredder due to uneven force or excessive force; on the other hand, a number of shredded papers are fixed on the cutter shaft of the shredder. Blades and spacers.
• the present invention discloses an integrated shredder tool processing process for processing an integrated shredder tool, the integrated shredder tool including a cutter shaft and a spacer protrudingly disposed on the cutter shaft
• the blade includes the following steps:
• the present invention extrudes the material at the arbor of the rod-shaped metal profile to the blade by extrusion, which not only saves material, but also has a single processing step, is easy to operate, and has low cost.
• the step (2) specifically includes a roughing process and a finishing process, the roughing process comprising: pressing the material in the first region along a radial direction of the metal profile such that the material of the first region Flowing to the second region, thereby forming a trapezoidal groove in the first region, forming a trapezoidal convex body in the second region, and the groove and the convex body surrounding the circumferential direction of the metal profile; the finishing process includes : continuing to press the material in the first region along the radial direction of the metal profile, so that the material at the groove flows toward the convex body, and finally the cutter shaft is formed at the bottom of the groove groove, and the blade is formed at the convex portion, the first region Form the knife shaft.
• This solution makes the invention easy to process and has a high yield.
• the end of the blade is further formed with a V-shaped groove.
• the step (2) further includes a grinding process after the processing, and grinding the end of the blade to facilitate cutting of the paper by the blade.
• the integrated shredder tool processing process further comprises the step (3) of forming a knife using a nailer and welding at least one of the tips at the end of the blade.

• the present invention discloses an integrated shredder tool processing 10 for processing an integrated shredder 20, the integrated shredder 20 including a cutter shaft 21 and spaced apart projections A blade 22 on the cutter shaft 21.
• the integrated shredder tool processing process 10 includes the following steps:
• the metal profile 51 is divided into a plurality of first regions and a plurality of second regions along the axial direction thereof, the first region and the second region are spaced apart, and the first portion is pressed along a radial direction of the metal profile
• the material in the region causes the material of the first region to flow to the second region, thereby forming the blade 22 in the second region, the first region forming the cutter shaft 21, as shown in Figure 6c.
• the metal profile 51 is a metal round bar.
• the step S12 specifically includes:
• finishing process continuously pressing the material in the first region along the radial direction of the semi-finished metal profile 52, so that the material at the groove 521 flows toward the convex body 522, and finally forming the cutter shaft at the groove bottom of the groove 521 21, the blade 22 is formed at the convex body 522, thereby forming an integrated shredder cutter 20, as shown in Fig. 6c.
• the end portion of the blade 22 is further formed with a V-shaped groove 23.
• the step S12 further includes a grinding process after the step S202, and the end of the blade 22 is ground and cut to facilitate the cutting of the paper by the blade 22.
• the integrated shredder tool processing process 10 further includes:
• the tip is formed using a nailing machine, and at least one of the tips 24 is welded to the end of the blade 22.
• the integrated shredder tooling process 10 further includes:
• At least one cutting edge 24 is scooped at the end of the blade 22.
• the step S12 can form the cutter shaft 21 and the blade 22 by using a twisting process or a rolling process.
