Description
本創作關於一種鋸料機之刀座驅動結構改良,尤指一種可使刀座移動速度更穩定及自動調整裁切推進速度之鋸料機。 This work is about the improvement of the driving structure of the knife seat of a sawing machine, especially a sawing machine that can make the moving speed of the knife seat more stable and automatically adjust the cutting speed.
一般來說,使用者在操作鋸料機時需要依照工件的材料特性調整鋸片進刀的裁切速度,且穩定的裁切速度也可以讓鋸料機具有較佳的裁切品質。舉例來說:一般硬度較低之工件可以用正常的進刀速度進行鋸切作業,若是硬度較高之工件則是要以較慢的進刀速度進行鋸切作業,避免鋸切不完全即強迫推進鋸片而造成鋸片損壞或減少使用壽命。如第1圖所示,係習知之鋸料機10構造,該鋸料機10設有一滑組於一滑軌組件11上之刀座12,該刀座12具有一鋸片電動機13驅動之鋸片14;一伸縮缸15設置於該鋸料機10上,該伸縮缸15具有一拉桿16,該拉桿16連結該刀座12,使該刀座12可於該滑軌組件11上移動,並以一操作裝置17電性連接該鋸料機10控制該鋸片14推進裁切或退回收縮;利用該鋸料機10在進行裁切工件時,針對工件之材質或特性,該操作裝置17調整該伸縮缸15的伸縮速度,以便調整該刀座12、鋸片14之進刀速度,換言之,工件質地較軟(例如:木材)用正常的進刀速度、工件質地較硬(例如:金屬)則以較慢的進刀速度;但是,上述之鋸料機10僅能適用於實心且材質、密度均勻之工件,若遇到空心材
質、不均質或鋁擠型...等工件即無法適用,該操作裝置17無法隨著該鋸片14裁切工件的位置改變進刀速度,該鋸片14以相同的進刀速度進行切鋸作業,反會對該鋸片14不利,此狀況在切鋸大形工件時尤為明顯,致使影響該鋸片14的使用壽命。且該伸縮缸15帶動該拉桿16之靈敏度較不易控制,在控制該拉桿16伸縮時較易產生頓挫感,進而影響工件之裁切品質,亦容易造成該鋸片14的損壞。因此,習知之裁切方式仍有其改良之必要。
Generally speaking, when operating the sawing machine, the user needs to adjust the cutting speed of the saw blade according to the material characteristics of the workpiece, and a stable cutting speed can also make the sawing machine have better cutting quality. For example: Generally, workpieces with low hardness can be sawed at a normal feed speed, and workpieces with high hardness must be sawed at a slower feed speed to avoid incomplete sawing and forced cutting. Pushing the saw blade in will result in damage to the saw blade or reduced service life. As shown in Figure 1, it is a known structure of

When the material of the workpiece to be sawed changes and the load on the saw blade changes, the saw blade current detector The sensor will detect this change, and the screw speed controller will change the screw speed accordingly, so that the knife seat can change the advancing speed of the knife, so that the sawing speed can be changed in real time to match the material of the workpiece, so as to avoid damage to the saw blade and Extended service life.
