Automatic saw used for impeller production technological process

Abstract

The invention discloses an automatic saw used for the impeller production technological process. The automatic saw comprises an auxiliary platform, an inside notch, lifters, a cutting platform, a base, a pusher, a movable gap, a limiting plate, a saw blade, a protecting cover, a motor, a fixed sleeve, a connecting plate, a piece plate, a rotary knob, a contraction strip, a hand holding plate, a piece groove, a bearing block, a lifting rod, a base plate, a gear clamp and a clamping opening. The automatic saw has the beneficial effects that the inside notch is formed in one side of the base, so that a movement space of a leg can be provided when a worker cuts away a gate and riser, accordingly the worker can have better controlling force, and precision cutting of the gate and riser is facilitated; by means of the auxiliary platform and the limiting plate, not only can cutting be guaranteed, but also the situation that iron filings fly in the motor and eyes of the worker to cause a machinery failure or a life threat can be avoided; and the fixed sleeve is connected through the contraction strip, and the rotary knob is arranged in the middle of the contraction strip, so that the fixing work of parts with various properties can be adapted, and displacement of the saw blade at the time of gate and riser cutting away also can be avoided.

Description

technical field [0001] The invention relates to a saw, in particular to an automatic saw used in the impeller production process, and belongs to the field of impeller production machinery. Background technique [0002] to avoid casting Supplementary part added to the top or side of a casting in the presence of a defect. Function In the casting mold, the cavity of the riser is a cavity for storing liquid metal. When the casting is formed, the metal is supplied to prevent shrinkage, shrinkage, exhaust and slag collection. The main function of the riser is Feeding, after the feeding process is completed, in order to ensure that the casting reaches the desired shape, it is necessary to remove the riser. Most of the existing technologies use a saw table to solve this problem, but this method has the situation that the cut is not smooth or the casting is damaged by too much cutting, which will make the whole part unusable, which not only wastes a lot of resources, but also great...

Problems solved by technology

Most of the existing technologies use a saw table to solve this problem, but this method has the situation that the cut is not smooth or the casting is damaged by too much cutting, which will make the whole part unusable, which not only wastes a lot of resources, but also greatly affects In order to improve production efficiency, even if the part is barely used, it will cause a great potential threat to the machinery using the part
