Description

Automatic punching device for composite extrusion piece

Technical Field

The utility model relates to the technical field of extrusion part processing devices, in particular to an automatic punching device for a composite extrusion part.

Background

Extrusion molding, also known as extrusion molding, is a manufacturing process involving the process of heating and melting a material in an extruder, then quantitatively passing the material through a die orifice at equal pressure, and finally forming a product with a uniform cross section. The technological process includes feeding plastic grains into the material cylinder, and pushing the plastic grains to the extruder head under the rotation of the screw. In this process, the otherwise loose solid feedstock is gradually compacted as it moves forward. Thanks to the heating outside the barrel and the friction shear effect between the screw and the inner wall of the barrel, the temperature of the raw material rises until it melts. The screw rod continuously and stably rotates to push the molten material to reach the machine head position, the material is quantitatively extruded at equal pressure, and then the material is cooled and shaped to obtain the finished product. The shape of the extruded product is generally consistent with the shape of the die orifice, and has a uniform cross section, such as the edges of PVC roof trim strips, roof rails, sunroofs, seat rails, and the like in automotive interiors and exteriors, which are typical application examples of the process. After the components are formed, the components are often subjected to subsequent processing such as stamping, sawing and the like according to different vehicle types or design requirements.

However, conventional stamping and sawing devices are often independent, and when the extruded parts are subjected to these processes, the products are transferred to the corresponding stamping stations or sawing stations in batches. Each workstation needs to be provided with special equipment and tools, so that not only is a large amount of workshop space occupied, but also when the extruded piece needs to be continuously punched and sawed, two clamping is needed, and the process is time-consuming and can possibly introduce more machining errors.
