Chip suction device for tubular workpiece cutting equipment

Abstract

The invention provides a scrap sucking device of tubular workpiece cutting equipment and belongs to the technical field of cutting equipment, solving the problem that existing mechanisms are applicable to cutting of cylindrical or rod-like non-hollow workpieces, and scraps falling into orifices of tubular workpieces are difficult to be sucked out. The scrap sucking device of the tubular workpiece cutting equipment comprises a suction tube, a collector and a driving mechanism. One end of the suction tube is a scrap sucking end abutted with an orifice of a to-be-cut workpiece while the other end of the suction tube is communicated with the collector; the driving mechanism is used for driving the suction tube to move so that the scrap sucking end can be switched freely between a scrap suction station and a separation station. The suction tube is aligned to the orifice to effectively suck the scraps falling into the workpiece, so that saw cutting precision of the workpiece is guaranteed and service lives of saw blades are prolonged. Besides, since the scrap sucking end can be switched freely between the scrap sucking station and the separation station, normal operations of cutting, conveying and discharging of the equipment cannot be affected.

Description

technical field [0001] The invention belongs to the technical field of cutting equipment, and relates to a cutting equipment for tubular workpieces, in particular to a chip suction device for cutting equipment for tubular workpieces. Background technique [0002] When using cutting equipment to cut tubular metal in sections, part of the sawdust generated falls on the frame, and the other part falls into the tube hole of the workpiece, and then falls into the sawing gap between the saw blade and the workpiece , This situation will cause the following problems: 1. The force on the saw blade will be uneven and the teeth will be damaged; 2. The sawing surface of the workpiece will be scratched by sawdust, and the precision will not meet the requirements. [0003] For this reason, it is very necessary to equip the cutting equipment with a special chip suction device, but the chip suction devices of various cutting equipment in the market generally cover the saw blade and the sawi...

Problems solved by technology

[0002] When using cutting equipment to cut tubular metal in sections, part of the sawdust generated falls on the frame, and the other part falls into the tube hole of the workpiece, and then falls into the sawing gap between the saw blade and the workpiece , this situation will cause the following problems: 1. Cause uneven force on the saw blade and damage the teeth; 2. The sawing surface of the workpiece is scratched by sawdust, and the accuracy cannot meet the requirements

[0004] The above-mentioned mechanism is more suitable for cutting non-hollow workpieces such as columns and rods, but for tubular workpieces, the sawdust falling into the pipe hole is difficult to be sucked out, and the effect is greatly reduced
