Problems solved by technology

In order to tighten the shreds, there is often a heavy lead pendant hanging from the lower end of the shreds. It is necessary to lift the lead pendant by hand before removing or hanging the shreds, which is a waste of time.

Abstract

The invention provides a material cutting machine. The material cutting machine comprises an operation table assembly, a support assembly, a supporting assembly, a rotating assembly and a cutting assembly, and further comprises a rectangular pedal, wherein a table leg transverse rod is arranged between two front operation table legs, the pedal is installed on the table leg transverse rod and can rotate with the table leg transverse rod as the axis, the front end of the pedal is located below a lead weight, and when the front end of the pedal is located at the highest point, the lead weight is supported by the pedal, and a cutting line is in a loosing state. A rotating shaft is adopted to drive materials to rotate, and regular circles can be cut out; the supporting assembly enables a support not to move easily when the machining is conducted; an upper screw rod and a lower screw rod rotate at the same time through a transmission shaft to regulate the position of the upper end and the lower end of the cutting line at the same time, and working efficiency is improved. The lower end of the cutting line is connected with the lead weight to tension the cutting line, and the appearance of a die which is cut out is much smoother. The pedal is further arranged, so that the cutting line is convenient to take down from or hang on an upper slide block, and the material cutting machine is convenient and rapid to use.

Description

technical field [0001] The invention relates to a material cutting machine, which belongs to the lost foam casting industry. Background technique [0002] Lost foam casting (also known as solid casting) is to bond and combine paraffin or foam plastic models similar in size and shape to the castings to form a model cluster. Press down and pour to vaporize the model, liquid metal occupies the position of the model, solidifies and cools to form a new casting method. Lost Foam Casting is a new technology with nearly no allowance and precise molding. This technology does not need to take molds, has no parting surface, and no sand core, so the casting has no flash, burr, and draft angle, and reduces the risk of damage caused by the core. Dimensional errors caused by combination. The surface roughness of the casting can reach Ra3.2 to 12.5μm; the dimensional accuracy of the casting can reach IT7 to 9; the machining allowance is at most 1.5 to 2mm, which can greatly reduce the cos...
