Metal rod cutting device and cutting method of metal rod

Abstract

The invention relates to equipment, belongs to the technical field of machining of metal rods, in particular to a metal rod cutting device and a cutting method of a metal rod. The metal rod cutting device comprises a cutting platform, wherein a cutter is mounted on the cutting platform; a plurality of roller shafts are mounted on the left side of the cutting platform; a first metal rod is arrangedon the roller shaft and can be moved rightwards; multiple groups of roller wheels are mounted on the left side of the cutting platform; each group of roller wheel at least comprises a front roller wheel and a rear roller wheel; the groups of roller wheels are also connected with an electromotor; a lifting air cylinder is mounted under each group of roller wheel; a corresponding part, which contacts a first metal rod, called as a contact point, is arranged between each of the front roller wheels and each of the rear roller wheels; when the air cylinders descend, the corresponding contact point, arranged between the each of the front roller wheels and each of the rear roller wheels, is separated from the corresponding first metal rod arranged on the corresponding roller shaft; and when theair cylinders ascend, the corresponding contact point, arranged between the each of the front roller wheels and each of the rear roller wheels, supports the corresponding first metal rod; and therefore, the metal rod cutting device and the cutting method of the metal rod disclosed by the invention have the advantages of being easy in cutting, reduced in consumption of saw blades of a cutting machine, and flat in end faces of second metal rods.

Description

Technical field [0001] The present invention relates to equipment in the technical field of metal rod processing, in particular to a metal rod cutting device and method. Background technique [0002] As the initial raw material, the metal rod (called the first metal rod) is relatively long, generally 4 to 5 meters, and its diameter generally reaches about 15 cm; when used, for example, in the manufacture of profiles or processed into automobiles For the wheel hub, the first metal rod should be cut into small pieces of metal rods (small pieces of metal rods are called second metal rods), and the length of the second metal rod is generally 20-30 cm. [0003] The cutting of the metal rod is carried out on a cutting device. The cutting device includes a cutting platform. A cutting machine is installed on the cutting platform. A plurality of rollers are installed on the left side of the cutting platform. The axis of the shaft is horizontally set back and forth. The first metal rod can ...

Problems solved by technology

[0003] Cutting the metal bar is carried out on the cutting device, the cutting device includes a cutting platform, the cutting machine is installed on the cutting platform, and a plurality of roller shafts are installed on the left side of the cutting platform, and the plurality of rollers The axis line of the shaft is set horizontally front and back, the first metal rod can run to the right when placed on the roller shaft, and the cutting of the metal rod can be completed when the first metal rod runs to the middle of the cutting machine; in the prior art, the metal rod There is no setting on the cutting device to turn the first metal bar back and forth, so that the cutting of the cut metal bar is cut from one side of the metal bar to the other side, Figure 4 It is a schematic cross-sectional view of the metal rod cutting process using the metal rod cutting device of the prior art. The shadow in the figure is the part that has not been cut, and the direction of the arrow F is the cutting direction, which has the advantages of laborious cutting and more saw blade consumption of the cutting machine. , The end surface of the second metal rod is uneven, etc.
