Abstract

The utility model relates to a circular sawing machine for cutting nonmetal, comprising a worktable arranged on a bed, a cantilever, a crankshaft box, an electric motor as well as a transmission mechanism, the utility model is characterized in that a plurality of saw blades with different sizes can be changed according to different demand at any time, meanwhile, the processing of a sheet metal, a square stock as well as a plurality of circular arc type even hollowed inner type nonmetal materials can be implemented through the cooperation of manual operation, the reciprocal speed of the saw blade is very high duo to the structures of the crankshaft, the piston and the cylinder in a gasoline engine used, therefore, the utility model is a new generation nonmetal cutting sawing machine which has the advantages of smooth cutting hyperplane, good degree of finish, small volume of the whole machine product, light weight, high efficiency, less energy consumption, long service life, convenient usage as well as wide use range.

Description

Winding saw bed

The utility model relates to a kind of sawing machine of cutting non-metal, and especially a kind of have a Winding saw bed round, camber curvilinear cut function.

The sawing machine of machining of non-metallic in the prior art generally has band sawing machine and circular sawing machine.Band sawing machine is generally bulky, and cost is higher, only uses in larger wooden processing factory, and the carpenter who is not suitable for vast handicraft uses; And circular sawing machine does not account for the place, so be subjected to user's welcome because volume can be done lessly.But no matter be band saw or circular sawing machine, processed timber can only moving linearly, promptly can only be processed into plate, square stock and is used to block etc., as desire timber is processed into the goods of circular curve shape, then is difficult to accomplish.Though the most ancient handsaw of carpenter can be sawed out the circular arc type goods, but labour intensity is big, inefficiency, the carpenter of Chu Xianing uses jigsaw in the market, though can overcome the shortcoming of falling above three kinds of saws substantially, but still exist cutting speed not high, and cut surface is rough, and the life-span, short, little camber line cutting was than shortcomings such as difficulties.

The purpose of this utility model is at deficiency of the prior art, and a kind of cutting speed height is provided, and cut surface is smooth, and machine life is long, can cut the Winding saw bed of various complicated circular arc type on-metallic articles.

Scheme of the present utility model is achieved in that this Winding saw bed, comprise lathe bed, be loaded on working plate, cantilever, crankcase, motor and transmission mechanism etc. on the lathe bed, piston in the cylinder body that is loaded on crankcase top links to each other with bent axle by connecting rod, the fastening connecting axle in piston upper end, connecting axle pass its top of cylinder body and the saw blade lower end affixed, the other end of saw blade snaps in the edge wire casing of pressing plate, pressing plate and fixed block are connected into one and the lifting shaft lower end joins, lifting shaft is fixed in the support arm through hole with screw, and support arm is installed on the lathe bed through column.

The utility model can be according to the different needs saw blade of conversion different size at any time, simultaneously by manual cooperation, realize the on-metallic article of processing plate, square stock and circular arc type even inner knockout shape, and owing to adopted the bent axle in the petrol engine, piston, air cylinder structure, thereby saw blade has very high reciprocating speed, cut surface is smooth, fineness good, the machine product volume is little, in light weight, the efficient height, power consumption is few, and the life-span is long, be a kind of easy to use, the nonmetal cutting sawing machine of broad-spectrum a new generation.

Below in conjunction with accompanying drawing embodiment of the present utility model is described in detail.

Fig. 1 is a general structure schematic diagram of the present utility model;

Fig. 2 is crankcase assembly of the present utility model and cylinder body heart cutaway view;

Fig. 3 is the utility model pressing plate and lifting shaft installation diagram;

Fig. 4 is the utility model working plate installation diagram.

As shown in Figure 1 and Figure 2, the utility model is installed on motor 40, column 38, pole 30 and compositions such as crankcase 19 and transmission mechanism on the lathe bed 41 by lathe bed 41.Bent axle 16 both sides are contained in the crankcase 19 by bearing 18, and its two ends is stretched out outside the crankcase 19, and interface seals with sealing ring 17.Belt pulley 22 is anchored on bent axle 16 external parts by pad 23 and mother Luo 24.Connecting rod 20 1 ends join by needle roller axle 21 and bent axle 16, the other end then joins by needle bearing 15 and the piston pin 14 that crosses piston 11 endoporus and located by ring washer 13, piston 11 tops are by Luo female 9 and pad 10 fastening connecting axles 4, connecting axle 4 passes the cylinder body lid 8 that engages with cylinder body 12, and by sealing ring 6 and pressing plate 5 fit sealings.The copper sheathing 7 of location and lubricating and wear-resisting effect also has been housed between cylinder body lid 8 and the connecting axle 4, and a translot is left at the other end top of connecting axle 4, and an end of briquetting 2 and saw blade 1 inserts in it jointly, and clamps by gripping sleeve 3.As shown in Figure 3, the other end of saw blade 1 is inserted and is leaned in the edge wire casing of pressing plate 35, and pressing plate 35 is connected into one by pad 33 and Luo mother 32 with fixed block 34, and is connected by the bottom of pin 36 with lifting shaft 31.Lifting shaft 31 passes the through hole on the support arm 37, and fixes in the pod of being left by its surface of screw jacking on the support arm 37, and support arm 37 is fixed on the lathe bed 41 by column 38.

As shown in Figure 4, sleeve pipe 27 is gone up in the welding of the bottom of working plate 26, and support pipe 30 is inserted in it and fixes with screw 29, mother Luo 28, and the other end of support pipe 30 is installed on the lathe bed 41.

During work, motor 40 drives bent axles 16 and rotates by belt 25, belt pulley 22, and bent axle 16 drive link 20 do reciprocating linear motion piston 11 and fastening connecting axle 4 and saw blade 1 on it.Need the workpiece of processing to be placed on the working plate 26, regulate lifting shaft 31, pressing plate 35 gently is pressed on the workpiece, prevent workpiece vibrations when cutting, it is degree that the degree that compresses can promote still with hand that workpiece moves.When needing cutting, push workpiece to saw blade 1, about adjust power thrusts, can saw out the shaped form shape of various complexity.Because the upper end card of saw blade 1 leans against in the wire casing at pressing plate 35 edges, has guaranteed the rectilinear motion of saw blade 1, and can be crooked, the wire casing of pressing plate 35 can be provided with several, looks the different in width of saw blade 1 and selects one.Unclamp screw 29, can rotation work platen 26 inclination certain angles, with convenient processing.

Back and forth movement owing to piston 11 increases the air pressure at cylinder body 12 tops, and lubricating oil is long-pending many, so between cylinder body lid 8 and crankcase 19, connect a decompression oil return pipe 39, with attenuating air pressure, and reclaims the bottom of lubricating oil to crankcase 19.
