Description
Technical Field
The invention relates to the technical field of cutting of long-strip objects, in particular to a handheld pneumatic saw cutting device which is used for quickly cutting off the long-strip objects and has good section flatness.
Background
During the debugging period of the extruded products of the extruding machine, more waste products appear, and operators need to saw the long-strip-shaped waste products into a certain length and collect the long-strip-shaped waste products, so that the long-strip-shaped products need to be quickly sawed in a short time inevitably. In the past, the small hacksaw is used manually by a bench worker. It is inefficient. The time for sawing this waste is limited, since the extruder operator is mainly working not to dispose of the waste. In order to pursue speed, the sawing speed must be increased, which makes the personnel labor intensive. If the angle grinder is used for cutting, smoke is generated and harmful to human bodies. Moreover, the diameter of the electric angle polishing handle is too large, and the minimum weight is about 2 kilograms, so that the electric angle polishing handle is only suitable for operating the polishing machine by two hands. Especially for female workers: when a workpiece is held by one hand and the angle grinder is held by the other hand to cut a long-strip product, the cutting stability is poor, the sawed section is not flat (sometimes a fault occurs in an extrusion molding machine set, so that the length of the product exceeds the tolerance of the product, or a long product is extruded due to the fact that the automatic cutting machine set stops cutting due to the fault, the length of the sawed product does not reach the standard, the length of the sawed product needs to be cut into the preset length, namely the product needs to be sawed, and the sawed section has a high requirement on the flatness at the moment), and the electric angle is very dangerous when the angle grinder is used for operating. However, in order to cut quickly, a single person must hold the plastic part with one hand and the power tool with one hand, and therefore, the power angle grinder is not suitable for this purpose. The mode of sawing by using a manual steel saw is conceivable, so that the sawing machine is not only tiring, but also has rough and uneven fracture and can not meet the requirement of product quality. A tool which simultaneously meets 3 conditions of light weight, small size of a handle and low rotating speed is found according to the conventional thought. But the reality is that: the electric tool has overlarge weight and size of a handle; the rotating speed of the conventional pneumatic tool exceeds the limit rotating speed of the saw blade, and the conventional pneumatic tool can smoke and scorch the cross section when being used. The method comprises the following steps: the skilled person, either empirical or common knowledge, would exclude the use of both tools to cut the above-mentioned products. The existing cutting machine of the woodworking cutting tool can also be used for the woodworking cutting tool, but the woodworking cutting tool has the defects of overlarge volume, high noise, large saw kerf, more sawdust and poor flexibility. Since it does not use rotary cutting, the large diameter pipe is realized by increasing the size of the saw blade, which is limited, and the versatility is poor, the facility is large and heavy, and the equipment is expensive.

Example (b):
the pneumatic polishing machine selects a grip with a weight of 0.9Kg and a diameter of 40 mm, and has an idle speed of 5000 prm. The saw blade protective cover is very suitable for being held by a single hand, and after the self-made saw blade protective cover is additionally arranged, the safety and reliability of the use by the single hand can be ensured; since the idling speed of most pneumatic tools is in the range of 1 to nearly 3 million prm, this is not the case. The idle speed of the pneumatic tool is the hard 'slow' speed of the pneumatic tool, and the idle speed is suitable for the idle speed. When the cutting speed is high, the vibration is large and dangerous, and smoke is generated in the cutting process. Of course, the tool is used, and the saw blade with the small diameter and the cut depth is selected as much as possible for safety and smoke generation during cutting, so that the linear speed of the tooth part of the saw blade is reduced. Conventional pneumatic tools may have a rotational speed that exceeds the safe rotational speed of the alloy saw blade (which can only be used with fine-toothed saw blades, if the workpiece is not fixed, held with one hand, and rotated with that hand, and if the workpiece is damaged or damaged due to jumping of the workpiece and the pneumatic tool with a coarse-toothed saw blade), which can be used with power angle grinders, the minimum weight and size of which are not suitable for this purpose. Assembling an alloy fine-tooth saw blade with a proper diameter; self-made saw blade shield; the fast clamp and the marking device which are simple and easy to pass through and can be adjusted according to different product specifications are manufactured by a user (marks are marked according to the specifications of conventional products by marking, so that the adjusting speed can be greatly increased). In order to reduce the friction between the saw blade and the product, a circular hole into which the saw blade can be just placed is used as a clamp, the saw blade is divided into two times on a tool grinding machine by a butterfly-shaped grinding wheel with proper diameter size, and the two end surfaces except the saw teeth are ground off by a certain amount (for example, 0.15 mm). So that the friction area between the saw blade and the product is reduced during cutting, the load of the saw blade is reduced, and the possibility of smoking is reduced. The inserting plates with different sizes are arranged on the movable hand plate during cutting so as to be suitable for being used as a dependence on cutting advancing during cutting, and the cutting is more stable and safer. It should be noted that: the fine-toothed saw blade has the advantages of moderate linear speed, dependence in cutting, small diameter of a tool holding part and light weight, and is the basic key point of the application. The invention is an important guarantee of using a single hand-held cutting tool mode, and also breaks through the important reason that the conventional powered tool is considered to be unstable, is easy to cause safety accidents and is not involved by people. The cutting devices are combined with the worktable to form a whole set of simple, convenient and flexible cutting facilities.
The using method comprises the following steps: firstly, the adjustable fixture is fixedly installed on one side of a workbench, then a long strip tubular product to be cut is placed in a pair of V-shaped grooves of the adjustable fixture, the position to be cut is aligned with a cutting seam between the V-shaped grooves, a butterfly nut is unscrewed, a sliding block is adjusted according to scale marks arranged on a sliding block fixing seat and the side wall of the sliding block, the long strip tubular product is limited in the V-shaped grooves through mutual matching of a limiting supporting plate and a supporting plate, the butterfly nut is screwed down to fix the sliding block, a user holds a cutting device by one hand, the cutting device is started, cutting is started from the position of the cutting seam, when the cutting saw blade is cut to a certain depth, a protective cover is in contact with the limiting supporting plate, the situation that the cutting saw blade is damaged too deeply is avoided, at the moment, the other hand.
When necessary, a movable material blocking mechanism or a marking mechanism can be additionally arranged on the workbench during cutting. The cutting length is quick and accurate. To the bigger product that can not be held in one hand, can install the quick assembly disassembly who has a plurality of handles temporarily additional and embrace the clamp, under the assistance of bracket, the hand dish is embraced and is pressed from both sides and make the product rotatory. This is also done by a single person and allows pipes of relatively large diameter to be cut easily (which is more difficult to perform quickly and with a rough profile for manual sawing). Large diameter pipes are also difficult to cut with woodworking cutters because of their small throat.
The above description is only a preferred embodiment of the present invention, and not intended to limit the scope of the present invention, and all equivalent structural changes made by using the contents of the present specification and the drawings, which are directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
