Aluminium extrusion mould for anti-theft spacer base

Saw Machine

The circular saw band is tensioned on two saw wheels, and the saw wheels drive the saw band to cut. There are two main types of band sawing machines: vertical and horizontal.

The saw frame of the vertical band sawing machine is set vertically, and the workpiece moves during cutting, which is used to cut the curved contour of the sheet and formed parts. The saw band can also be replaced with a file chain or abrasive belt for repairing or grinding.

The saw frame of the horizontal band sawing machine is arranged horizontally or obliquely, and is fed in the vertical direction or in the direction of swinging around a point. The saw band is generally twisted by 40° to keep the saw teeth perpendicular to the workpiece.

Horizontal type is divided into scissors type, double column, single column type band sawing machine; according to the use situation, it can be divided into manual type (economic type, manual feeding and manual cutting of materials), automatic type; according to the automation program using the controller, it can be divided into manual type ( Semi-automatic manual feeding) Fully automatic type (automatic feeding and automatic cutting)

Working Principle of Aluminum Extrusion Die

It is not easy to be widely used in many fields, but aluminum profiles can do it, and it can be seen everywhere in life and work. The prototype of the aluminum profile is not like this, it needs to be processed, and it is extruded through an aluminum profile mold, and this aluminum profile mold also needs to be made first.
Let's first understand the forming steps of aluminum profiles. The aluminum profile processing process includes batching, rolling, extrusion, stretching, forging and other steps. Generally, factories will directly heat aluminum rods, and then extrude them through dies to obtain aluminum profiles of different cross-sections. , To put it simply, it is casting, extrusion and forming.
Extrusion requires an aluminum profile mold. The material of this industrial Aluminum Profile Extrusion Mold is H13 steel, and the mold needs to be nitrided before it can be used. Generally, a set of molds consists of three parts: the positive mold, the mold pad and the mold sleeve. The positive mold is composed of working belt, empty knife, deflector and other parts, and each component has its own function.

When extruding, the ingot is still under the strong extrusion force, and is divided into several strands of metal by the knife (bridge part) of the mold and flows into the welding chamber of the mold.
 The formed gap flows out to form a hollow product of the required shape and size, and the number of welds of the product is the same as the number of strands of the metal flow.
