Double-ended metal circular sawing machine

Abstract

The invention provides a double-ended metal circular sawing machine, and belongs to the mechanical technical field. The double-ended metal circular sawing machine solves the problem that an existing double-ended metal circular sawing machine is low in processing precision. The double-ended metal circular sawing machine comprises a rack, wherein a guide rail is arranged on the rack; a first slide plate and a second slide plate are arranged on the guide rail; a first lead screw is arranged on the bottom of the firs slide plate; a second lead screw is arranged on the bottom of the second slide plate; drive motors are arranged on the first slide plate and the second slide plate; circular saw blades are arranged on output shafts of the drive motors; a drive source and a fixing structure for fixing a workpiece are arranged on the rack; the fixing structure comprises a two positioning notches which are positioned between two circular saw blades; one end of the first lead screw is connected with the drive source; the other end of the first lead screw is fixedly connected with a first gear; one end of the second lead screw is fixedly connected with a second gear; and the first gear is engaged with the second gear. The double-ended metal circular sawing machine has the advantage of high processing precision.

Description

technical field

[0001] The invention belongs to the technical field of machinery and relates to a double-head metal circular saw machine. Background technique

[0002] Metal circular saws are widely used in pipe fitting hardware manufacturers. The products cut by metal circular saws have smooth cuts and no burrs. The quality of the cuts is basically close to wire cutting, and the production cost is only one tenth of wire cutting. However, at present The size locator randomly equipped with the metal circular saw machine is too simple, the positioning adjustment is troublesome, the positioning accuracy is poor, and the repeatability is poor.

[0003] In response to the above problems, people have made various improvements, and some have applied for patents. For example, Chinese patent literature discloses a positioning device for cutting bent pipes [application number: 201220058057.3; authorized announcement No.: CN202462071U], it comprises the main platen that is fixedly arr...

Embodiment 1

[0026] This double-head metal circular saw machine is mainly used for cutting the two ends of the elbow 19, such as figure 1 As shown, the double-head metal circular saw machine includes a frame 1, a driving source 2, a guide rail 3, a fixed structure 4, a first sliding plate 5, a second sliding plate 6, a first screw rod 7, a second screw rod 8, A first gear 9 , a second gear 10 , a drive motor 11 and a circular saw blade 12 .

[0027] The driving source 2 , the guide rail 3 and the fixing structure 4 are all fixedly connected to the frame 1 . The driving source 2 is a motor, and the number of guide rails 3 is a pair. The guide rails 3 are provided with a first sliding plate 5 and a second sliding plate 6, and the bottoms of the first sliding plate 5 and the second sliding plate 6 are fixedly connected with sliders. 18, the slider 18 is connected with the guide rail 3, the first sliding plate 5 and the second sliding plate 6 are provided with a driving motor 11, and the outp...

Embodiment 2

[0032] The structure and principle of this embodiment are basically the same as that of Embodiment 1, the difference is that in this embodiment, the fixed structure 4 includes a fixed frame 42, the top of the fixed frame 42 has a fixed groove 43, and both ends of the fixed groove 43 have The positioning notch 41 and the top of the fixing frame 42 are provided with a compression oil cylinder, the piston rod of the compression oil cylinder is fixedly connected with a compression plate 45 , and the compression plate 45 is located above the positioning notch 41 .

Embodiment 3

[0034] The structure and principle of this embodiment are basically the same as that of Embodiment 1, the difference is that in this embodiment, the first screw mandrel 7, the second screw mandrel 8 and the guide rail 3 are all arranged in the vertical direction, and the first screw mandrel 7 1. The second threaded mandrel 8 is parallel to the guide rail 3, the fixed structure 4 is located on one side of the guide rail 3, and the feeding mode of the circular saw blade 12 is to feed up and down along the vertical direction.
