Efficient and stable metal casting riser wire cutting instrument and process

Abstract

The invention provides an efficient and stable metal casting riser wire cutting instrument and technology, and relates to the technical field of metal casting machining.The efficient and stable metal casting riser wire cutting instrument and technology comprise a base and supports installed on the two sides of the top of the base, a top plate is fixed to the tops of the supports, and a motor base is installed at the bottom of the top plate; the efficient and stable metal casting riser wire cutting instrument comprises two supports, a motor base is installed on the two sides of the bottom of the motor base, guide wheels are movably installed on the two sides of the bottom of the motor base, a motor is installed on the motor base, a driving wheel is installed at the end of an output shaft of the motor, and a transverse frame is fixed between the two supports and located below the guide wheels. The outer ring and the fixed wheel are connected through a spring, so that the regulation and control wheels on the two sides flexibly support the saw rope, the situation that the service life of the saw rope is affected due to the fact that the saw rope is stressed excessively is avoided, the bottom end of the flexibly-fixed saw rope easily floats up and down slightly in the transmission process, the force applied by the saw rope to a riser is changed, the probability that the saw rope is clamped at the riser is reduced, and practicability is good.

Description

technical field [0001] The invention relates to the technical field of metal casting processing, in particular to an efficient and stable metal casting riser wire cutting device and technology. Background technique [0002] Steel castings refer to parts made of cast steel, which have similar properties to cast iron, but are stronger than cast iron. Steel castings are prone to defects such as air holes and inaccurate angle positioning during the casting process, and the casing may break during long-term use. A riser is a supplementary part added to the top or side of a casting to avoid defects in the casting. 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. Risers with different design functions have different forms, sizes and opening positions. During the riser production proc...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides an efficient and stable metal casting riser wire cutting device and process, which solves the problem that when the riser is cut, it is easy to tighten the saw wire, causing it to be overstressed and affect the service life. At the same time, the problem of poor fixing effect of metal castings
