Automatic thermal cutting apparatus for riser of abrasion- resistant sleeve casting

Abstract

The present invention relates to the field of casting processing, and more particularly to an automatic thermal cutting apparatus for a riser of an abrasion-resistant sleeve casting. The automatic thermal cutting apparatus comprises a thermal cutting machine, a horizontally arranged substrate, a feeding trough, a material moving mechanism, and a uniform rotation mechanism. The material moving mechanism comprises a casting supporting table. The uniform rotation mechanism comprises a driving motor and a casting fastening component, wherein the casting fastening component comprises an air shaft and a plurality of arc-shaped snap plates disposed outside the air shaft in a sleeving manner; all the arc-shaped snap plates are connected end to end so as to form a hollow cylindrical structure thatis disposed outside the air shaft in a sleeving manner; and the end portions of exterior walls of all the arc-shaped snap plates are sleeved with elastic snap members. An abrasion-resistant sleeve iscoaxial with the drive motor when placed on the casting supporting table, and a cutting head of the thermal cutting machine is located above a riser root of the abrasion-resistant sleeve. According tothe automatic thermal cutting apparatus for a riser of an abrasion-resistant sleeve casting, the riser of the abrasion-resistant sleeve casting can be automatically and thermally cut, time and manpower are significantly saved, and applicability of the automatic thermal cutting apparatus is high.

Description

technical field [0001] The invention relates to the field of casting processing, in particular to an automatic thermal cutting device for wear-resistant sleeve casting risers. Background technique [0002] In the process of metal casting, due to the needs of the process, in addition to the shape and specifications of the workpiece itself, the body of the casting also has some "redundant" structural parts. This part is usually called the pouring riser, and the riser refers to In order to avoid casting defects, the supplementary part added to the top or side of the casting, the function is in the casting mold, the cavity of the riser is the cavity for storing liquid metal, and the metal is supplied when the casting is formed, which can prevent shrinkage cavity and porosity , Exhaust and slag collection, while the main function of the riser is feeding. [0003] The common methods of removing sprues are physical cutting methods, including hot cutting methods such as flame, plas...

Problems solved by technology

Among them, the latter, as a common application method with simple operation and low cost, is widely used in the actual production process. In casting production, the removal of casting risers is a labor-intensive process with a low degree of automation. At present, the common manual or semi-automatic sawing and cutting methods are circular saw blade cutting and band saw cutting. Although the cost of equipment and consumables is relatively low, the requirements for workers' operation are high, and the safety of cutting production is low. Therefore, , with the advancement of technology and the continuous increase of labor costs, the market demand for automatic cutting machines for casting risers is becoming increasingly obvious
