Abstract
The utility model provides a cylinder body cutting saw which comprises a main saw blade, wherein the lower edge of the main saw blade is provided with sawteeth, a grinding strip is pasted above the sawteeth, and rough grinding lines are made on the surface of the grinding strip; and the two ends of the grinding strip and the two ends of the main saw blade are provided with fixing holes which are mutually matched with one anther and are assembled on a sawing machine. The saw can be used for grinding edges of blank while the blank of the cylinder body is obtained by sawing, so that the blank of the cylinder body is enabled to have glabrous edges after one-step sawing of the sawing machine.
Description
Affiliated technical field
The utility model relates to hydraulic cylinder production equipment field, especially relates to a kind of saw cutter that is used for cutting out from huge cylinder body raw material body the hydraulic cylinder blank.
Background technology
In the production process of hydraulic cylinder; Need to adopt sawing machine to get the blank that constitutes main body cylinder block from large-scale tube type material saw; Then the burr of cylinder blank is rejected, adopt milling machine that the end face of blank is carried out fine finishining again, adopt boring machine that the inwall of blank is carried out fine finishining; To obtain the higher main body cylinder block of precision, again at one of which side assembling end cap.
In said process, the sawing machine hard iron is got the sawtooth that cylinder blank need rely on saw cutter lower edge, and sawtooth is in the dragsaw process; Will make the edge of cylinder blank produce a large amount of burrs, roughness is bigger, and this kind burr is not only bad for the processing of subsequent handling; And probably scratch staff's hand, therefore need in time handle, generally speaking; This kind situation is to polish with rubber or emery wheel through manual work, however this kind polishing mode waste time and energy, seriously limited production efficiency.
The utility model content
To the problems referred to above, the purpose of the utility model is to provide a kind of cylinder body cast-cutting saw cutter, and this saw cutter can carry out grinding to the blank edge when hard iron is got cylinder blank, has bright and clean edge thereby make through the once huge cylinder blank of getting of sawing machine.
The utility model solves the technical scheme that its technical problem adopted: this cylinder body cast-cutting saw cutter comprises the head saw bar, and this head saw bar lower limb has sawtooth, and a grinding bar is posted in said sawtooth top, and this grinding bar surface is shaped on coarse grinding lines; And that said grinding bar two ends and said head saw bar two ends have is that the position cooperatively interacts, be used to be assemblied in the fixing hole on the sawing machine.
As preferably, the binding face of said grinding bar and said head saw bar is matsurface, to increase in the grinding process skew resistance between said grinding bar and the head saw bar.
As preferably, offer the groove that is used to set said grinding bar on the said head saw bar.
As preferably, the lower limb of said grinding bar is an inclined-plane that is tilted to said head saw bar surface gradually, to reduce the resistance of cylinder blank to said grinding bar lower limb.
The beneficial effect of the utility model is: this cylinder body cast-cutting saw cutter in use, under sawing machine drove, the sawtooth of head saw bar lower limb at first cut cylinder blank; After forming otch, continue cutting inward, simultaneously; The grinding bar carries out grinding to the otch that already forms, thereby eliminates burr, gets in the process of cylinder blank at hard iron once; Cylinder blank is carried out grinding, thereby the cylinder blank that hard iron is got has bright and clean edge, so that the subsequent handling operation.
Description of drawings
Fig. 1 is the front view of an embodiment of this cylinder body cast-cutting saw cutter.
Fig. 2 is the exploded view of Fig. 1 embodiment.
Fig. 3 is that the A-A of Fig. 2 is to cut away view.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified:
In the embodiment of Fig. 1-shown in Figure 3, this cylinder body cast-cutting saw cutter comprises head saw bar 1, and this head saw bar 1 lower limb has sawtooth 11, and a grinding bar 2 is posted in said sawtooth 11 tops, and these grinding bar 2 surfaces are shaped on coarse grinding lines; And that said grinding bar 2 two ends and said head saw bar 1 two ends have is that the position cooperatively interacts, be used to be assemblied in the fixing hole 3 on the sawing machine.
Above-mentioned cylinder body cast-cutting saw cutter; Offer the groove 12 that is used to set said grinding bar 2 on the said head saw bar 1; After in grinding bar 2 is embedded at this groove 12, the intensity of head saw bar 1 and grinding bar 2 is strengthened each other, and can prevent the relative displacement of grinding bar 2 and head saw bar 1.
Above-mentioned cylinder body cast-cutting saw cutter, as shown in Figure 3, the lower limb of said grinding bar 2 is an inclined-plane 21 that is tilted to said head saw bar 1 surface gradually, to reduce the resistance of cylinder blank to said grinding bar 2 lower limbs.
The bar of head saw shown in it is pointed out that 1 can also be one-body molded with said grinding bar 2.
Above-mentioned body cast-cutting saw cutter in use, under sawing machine drove, the sawtooth 11 of head saw bar 1 lower limb at first cut cylinder blank; After forming otch, continue cutting inward, simultaneously; The otch that 2 pairs of grinding bars already form carry out grinding, thereby eliminate burr, get in the process of cylinder blank at hard iron once; Cylinder blank is carried out grinding, thereby the cylinder blank that hard iron is got has bright and clean edge, so that the subsequent handling operation.
The above is merely the preferred embodiment of the utility model, and is in order to restriction the utility model, not all within the spirit and principle of the utility model, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
