本創作係有關於一種切削機構的設計，特別是指一種鋼材表面粗化之切削機構。This work is about the design of a cutting mechanism, especially a cutting mechanism for roughening the surface of steel.

按，為使不同外徑之鋼材有效受到夾持以利進行工程作業，一般會在該鋼材的端部上進行粗化處理，透過粗化處理後使該鋼材形成表面粗化之端部得以有效受到夾持，以免該鋼材表面過度光滑平整無法受到穩定夾持而影響工程作業的進行；惟，在目前的粗化處理作業上，皆是以人工以手持工具方式對該鋼材的端部進行粗化處理，以使該鋼材之端部形成粗化效果，因此在進行粗化處理過程中全憑現場人員之工作經驗來進行調整，所以一次僅能對一鋼材的端部進行處理，故對於外徑較小之鋼材的端部，以人工方式進行便可快速成型出所需的粗化態樣，倘若為外徑較大之鋼材者，其在處理上不但繁瑣又費時外，同時也因為是利用人工以手持工具方式進行，其將導致該端部粗化程度形成不一，且會有偏差，致使完成後馬上應用於工程作業使用時，更會因粗化程度不一的狀態而使得在夾持受力上無法有效呈穩定與平均，致使影響後續工程作業的進行，有待改進。According to the press, in order to effectively clamp the steel with different outer diameters to facilitate engineering operations, roughening treatment is generally performed on the end of the steel. It is clamped to prevent the surface of the steel from being too smooth and flat and unable to be clamped stably, which will affect the progress of engineering operations; however, in the current roughening treatment operations, the ends of the steel are manually roughened by hand-held tools. Therefore, during the roughening process, all adjustments are made based on the working experience of the field personnel, so only the end of one steel can be processed at a time, so the external The end of the steel with a smaller diameter can be quickly formed into the desired roughening shape by manual means. If it is a steel with a larger outer diameter, it is not only cumbersome and time-consuming to process, but also because it is Manually using hand-held tools will lead to different roughening degrees of the end, and there will be deviations, so that when they are used in engineering operations immediately after completion, the roughening degree will be different. The clamping force cannot be effectively stabilized and averaged, which affects the subsequent engineering operations and needs to be improved.

參閱圖1及圖2，當進行粗化處理作業時，首先利用該進料固定座42夾持該鋼材5，而分別作動該等頂掣件341與該等車刀333遠離該開孔323處，這時便可緩慢連動該進料固定座42夾持該鋼材5往該切削機構3處移動，以使該鋼材5之端部進入至該開孔323處，而後分別作動該轉盤32上之該每一調整件342，以作動該頂掣件341於該調整槽322移動，以使該等滑輪b一一頂掣於該鋼材5的表面上，而後再透過該固定栓352將該定掣件341予以固定，以避免作動時該鋼材5無法有效受到該等頂掣件341穩定的頂掣夾持，同時再針對該鋼材5的尺寸大小與端部表面欲進行粗化程度來調整該等車刀333間的車削距離，例如欲形成的粗化紋路為較淺者或外徑尺寸較大者，如圖3A~圖3C所示，這時便可藉由該調整栓334於該調整孔332來調整該車刀333之刀刃a凸伸於該開孔323處的距離，便將該等刀刃a間的對應間距調整為較寬設置，倘若所欲形成粗化紋路為較深者或外徑尺寸較小者，如圖4A~圖4C所示，這時便可將該等刀刃a間的對應間距則調整為較窄設置，而後便可驅動該切削機構3產生轉動，同時在該切削機構3轉動過程中，一併連動該進料固定座42帶動該鋼料往該切削機構3處移動，使該鋼材5之端部被往該切削機構3內部推進過程中，因鑒於該頂掣件341對應該開孔323處的一端為該滾輪b的設置，因此當該鋼材被推進時，該滾輪b係會順沿該鋼材5之表面滾動，同時輔助該鋼材5往該等車刀333處移動時得以呈穩定狀態，並使該鋼材5逐漸受到該等車刀333之刀刃a的切削，且於該鋼材5端部之表面上形成紋路，而當完成粗化切削處理後，該進料固定座42便會帶動該鋼材5由該開孔323處退出，如此即能快速完成該鋼材5端部之表面粗化作業；是以，透過該車刀裝置33與該中心滾輪裝置34得以於該轉盤32上進行適當調整，以利因應不同外徑尺寸之該鋼材5的穩定夾持與不同粗化紋路的切削程序作業，係有別傳統僅能以人工方式來的快速且便利，故不但能提高粗化處理作業效率，更能簡化粗化處理程序，有效達到提昇該鋼材表面粗化效果。Referring to FIGS. 1 and 2 , when the roughening operation is performed, the steel material 5 is first clamped by the feed holder 42 , and the top catches 341 and the turning tools 333 are respectively actuated away from the opening 323 . At this time, the feed holder 42 can be slowly linked to clamp the steel material 5 to move to the cutting mechanism 3, so that the end of the steel material 5 enters the opening 323, and then actuate the Each adjusting piece 342 is used to actuate the top catch piece 341 to move in the adjusting groove 322 , so that the pulleys b are pushed against the surface of the steel material 5 one by one, and then the catch piece is passed through the fixing bolt 352 341 is fixed to avoid that the steel 5 cannot be effectively clamped by the jacks 341 stably during operation, and at the same time, the wheels are adjusted according to the size of the steel 5 and the roughening of the end surface. The turning distance between the knives 333 , for example, the roughening pattern to be formed is shallower or the outer diameter is larger, as shown in FIGS. 3A to 3C , at this time, the adjustment pin 334 can be used in the adjustment hole 332 to adjust Adjust the distance that the cutting edge a of the turning tool 333 protrudes from the opening 323, and then adjust the corresponding distance between the cutting edges a to a wider setting, if the roughening pattern to be formed is a deeper one or an outer diameter size The smaller one, as shown in FIG. 4A to FIG. 4C , at this time, the corresponding spacing between the cutting edges a can be adjusted to be narrower, and then the cutting mechanism 3 can be driven to rotate, and the cutting mechanism 3 can be rotated at the same time. During the process, the feed fixing seat 42 is also linked to drive the steel material to move to the cutting mechanism 3, so that the end of the steel material 5 is pushed into the cutting mechanism 3 during the process, because the top stopper 341 is opposite to the cutting mechanism 3. The end of the hole 323 should be the setting of the roller b, so when the steel is pushed, the roller b will roll along the surface of the steel 5, and at the same time assist the steel 5 to move to the turning tools 333. In a stable state, the steel material 5 is gradually cut by the cutting edges a of the turning tools 333, and lines are formed on the surface of the end portion of the steel material 5, and after the roughening and cutting process is completed, the feed holder 42 will drive the steel material 5 to withdraw from the opening 323, so that the surface roughening operation of the end of the steel material 5 can be quickly completed; Make appropriate adjustments on the 32 to facilitate stable clamping of the steel 5 with different outer diameters and cutting procedures for different roughening lines. It is different from the traditional speed and convenience that can only be done manually, so it can not only improve the The roughening treatment operation efficiency can simplify the roughening treatment procedure and effectively improve the surface roughening effect of the steel.

歸納前述，本發明鋼材表面粗化之切削機構，其主要藉由該轉盤二側分別可供該車刀裝置與中心滾輪裝置之設置，以使該切削機構可依所需要進行粗化處理之不同之鋼材外徑大小，及粗化程度效果不同，針對夾持間距與車削紋路深淺進行適當調整，俾便於每一該鋼材的端部表面上得以快速受到該車刀裝置的切削而形成穩定粗化效果，不但能更佳簡化處理程序，縮短處理時效，進而使該鋼材端部表面確實達成粗化處理之效果，故確實能達到本發明之目的。Summarizing the above, the cutting mechanism for roughening the steel surface of the present invention is mainly provided for the setting of the turning tool device and the center roller device by the two sides of the turntable, so that the cutting mechanism can be roughened according to different needs. The outer diameter of the steel and the effect of the roughening degree are different, and the clamping distance and the depth of the turning pattern should be adjusted appropriately, so that the end surface of each steel can be quickly cut by the turning tool device to form stable roughening. The effect can not only simplify the treatment procedure better, shorten the treatment time period, but also make the surface of the steel end part achieve the effect of roughening treatment, so that the purpose of the present invention can be achieved.
