Abstract
The invention discloses a pulping blade of a pulping machine and a machining method of the pulping blade. The machining method includes: forming a cylinder by means of centrifugal casting, and hobbing on the surface of the cylinder by the aid of a numerically-controlled gear hobbing machine. The cylindrical pulping blade is directly formed by forming the cylinder by means of centrifugal casting and then correspondingly lathing and hobbing the cylinder, so that deformation is reduced, forming the cylindrical pulping blade by combination is unneeded, assembly is convenient and rapid, assembly efficiency is greatly improved, and product qualified rate can reach 98%. Besides, teeth formed by direct hobbing are kept consistent and can be well coordinated in pulping, and accordingly pulping quality is improved.
Description
Technical field
The present invention relates to a kind of grinding plate of pulping machine and processing method thereof, belong to paper making equipment technical field.
Background technology
Abrasive disc in the fiberizer that papermaking defibrination is used is divided into and determines abrasive disc and moving abrasive disc according to its motion mode, mainly relies on the relative motion of determining between abrasive disc and moving abrasive disc in the time of defibrination, slurry is ground, therefore, the impact that abrasive disc is important on defibrination mass formation.As Figure 1-Figure 4, the moving abrasive disc using is at present all to involute a circular cylinder by 6 toothed arc-like sheets with determining abrasive disc, the moving abrasive disc of rounded cylindrical rounded cylindrical determine in abrasive disc, rotate, by the tooth on moving abrasive disc outer surface and the tooth of determining on abrasive disc inner surface, slurry is ground.
The toothed arc-like sheet that forms abrasive disc is conventionally directly poured into a mould and is formed by wear-resisting alloy steel, when cast, arc-like sheet easily produces distortion or has error, what 6 arc-like sheets cannot be assembled involute rounded cylindrical determines abrasive disc or moving abrasive disc, cause a large amount of arc-like sheets to scrap, waste production cost, and when assembling need to spend plenty of time coupling arc-like sheet, efficiency of assembling is low.On the other hand, because of only 2mm of the facewidth on arc-like sheet, space width is 3mm only, and tooth depth is 8mm only, and therefore, when moulding by casting, tooth is easily broken, and teeth groove is easily blocked; Meanwhile, because of the distortion that arc-like sheet produces, be assembled into even involutory and determined abrasive disc and moving abrasive disc, because determining the gap difference between abrasive disc and moving abrasive disc, also affected defibrination quality and even cannot cooperatively interact and carry out defibrination.Be subject to the impact of these factors, current abrasive disc manufacture assembling mode, its product percent of pass only has 30%.
Summary of the invention
Technical problem to be solved by this invention is to overcome defect of the prior art, and a kind of grinding plate of pulping machine and processing method thereof are provided, and changes the mode of existing process and assemble abrasive disc, and product percent of pass and efficiency of assembling are improved greatly.
For solving the problems of the technologies described above, the invention provides a kind of grinding plate of pulping machine, it is characterized in that, form and determine abrasive disc or moving abrasive disc in the inner surface of a cylinder or outer surface gear hobbing.
Described cylinder adopts centrifugal casting to form.
Grinding plate of pulping machine processing method based on claim 1, is characterized in that, comprises the following steps:
Adopt centrifugal casting to form a cylinder,
By chain digital control gear hobbing machine in drum surface gear hobbing.
Casting forms after cylinder, is also included in the step machining on cylinder, carries out gear hobbing after Vehicle Processing again.
After gear hobbing, also comprise the step of abrasive disc being carried out to line cutting.
When determining abrasive disc, processing in cylinder inner surface gear hobbing, processes while moving abrasive disc in cylinder outer surface gear hobbing.
The beneficial effect that the present invention reaches:
Abrasive disc of the present invention is to adopt centrifugal casting first to form cylinder, then on cylinder, carry out corresponding Vehicle Processing, gear hobbing, can directly form like this rounded cylindrical abrasive disc, reduce distortion, do not need to be combined to form rounded cylindrical abrasive disc yet, easy to assembly quick, efficiency of assembling improves greatly, and product percent of pass can reach 98%.Meanwhile, the tooth that directly gear hobbing forms is consistent, and can good fitly carry out defibrination, has improved defibrination quality.

Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.Following examples are only for technical scheme of the present invention is more clearly described, and can not limit the scope of the invention with this.
Its structure processing and manufacturing mode of grinding plate of pulping machine of the present invention had both been applicable to determine abrasive disc, was also applicable to moving abrasive disc.As shown in Figure 5, Figure 6, abrasive disc all adopts centrifugal casting directly to form a cylinder 30, then on cylinder 30, carry out corresponding Vehicle Processing, by chain digital control gear hobbing machine gear hobbing (not shown tooth), after gear hobbing, according to actual installation size, abrasive disc is carried out to line cutting again, form the abrasive disc that meets matching requirements.The abrasive disc forming like this can be avoided distortion, and easy to assembly quick, efficiency of assembling improves greatly, and product percent of pass can reach 98%.Meanwhile, the tooth of formation is consistent, and can good fitly carry out defibrination, has improved defibrination quality.
Determine abrasive disc 10 and be with the difference that moving abrasive disc 20 adds man-hour, determining abrasive disc 10 need to machine at cylinder 30 outer surfaces 11, is formed for multiple platforms 13 of assembling, in cylinder inner surface 12 gear hobbings; And moving abrasive disc 20 machines at cylinder 30 inner surfaces 22, be formed for multiple platforms 23 of assembling, in cylinder outer surface 21 gear hobbings, after gear hobbing, according to actual installation size, abrasive disc is carried out to line cutting again, form the abrasive disc that meets matching requirements.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the technology of the present invention principle; can also make some improvement and distortion, these improvement and distortion also should be considered as protection scope of the present invention.
