Punching equipment of aluminum alloy sections for building

Abstract

The invention provides punching equipment of aluminum alloy sections for building. The punching equipment comprises a work table, an upper mold, a lower mold, a lifting supporting seat and an air cylinder, wherein the upper mold is mounted on a bearing seat of a lifting plate through a rotating shaft; the lower mold is mounted on a bearing seat of a work slot position through a rotating shaft; a punching die head is arranged on each of a plurality of surfaces of the upper mold; a punch forming surface adapted to the corresponding punch die head is arranged on each of a plurality of surfaces ofthe lower mold; one end of the rotating shaft on the upper mold is in driving connection with a rotating block, the shape of the rotating block is the same as that of the upper mold, and end surfacesface the same direction; driving rods having different spacing heights are respectively arranged on end surfaces of the rotating block; an inserting slot adapted to the driving rods are formed in thework table; and a part of sawteeth of a gear of the rotating shaft on the lower mold are located in the inserting slot. When the punching equipment is used, a workpiece sleeves the lower mold, the upper mold rotates, the punch die head for processing is selected, the rotating block rotates to the end surface having the corresponding driving rod along with the upper mold, and when the upper mold falls, the driving rod is inserted into the inserting slot to drive the gear, so that the lower mold is driven to rotate to the corresponding punch forming surface.

Description

technical field [0001] The invention relates to the technical field of metal processing equipment, in particular to stamping equipment for aluminum alloy profiles used in construction. Background technique [0002] At present, aluminum alloy is the most widely used alloy. The density of aluminum alloy is low, but its strength is relatively high, which is close to or exceeds that of high-quality steel. It has good plasticity and can be processed into various profiles. It has excellent electrical conductivity, thermal conductivity and corrosion resistance. developed rapidly. In the forming process of aluminum alloys for construction, a stamping process is usually required. Stamping is a forming processing method that applies external force to plates, strips, pipes and profiles by presses and molds to cause plastic deformation or separation to obtain workpieces (stamping parts) of required shape and size. [0003] Usually a stamped part is not just stamped on one side, but of...

Problems solved by technology

However, most of the stamping equipment currently on the market can only perform a single stamping process, so the workpiece needs to be processed on one stamping equipment and then replaced with another stamping equipment for stamping, and the production process is cumbersome
