Punching machine for aluminium plate

Abstract

The invention discloses machining shaping mould equipment, and particularly relates to a punching machine for an aluminium plate. The punching machine for the aluminium plate comprises an upper mould frame, an upper mould, a lower mould frame and a lower mould, wherein the lower mould comprises a frustum, a sliding frame and sliding blocks uniformly distributed on the periphery of the frustum in the circumferential direction; the frustum and the sliding frame are fixed on the lower mould frame; the frustum comprises a small upper end and a large lower end; an inclined sliding groove is formed in the sliding frame; the inclined sliding groove and an adjacent inclined surface or conical surface of the frustum face the same direction; the sliding blocks are arranged between the sliding frame and the frustum; the sliding blocks are propped against the inclined surface or the conical surface of the frustum; the sliding blocks are connected with the interior of the inclined sliding groove; the upper end face of the frustum and the upper parts of the sliding blocks together form a profile matched with the inner surface of a finished good in shape and provided with an inner turned edge. According to the punching machine for the aluminium plate, disclosed by the invention, the defects of low production efficiency and high manufacture cost in the prior art are overcome; therefore, the punching machine capable of manufacturing the aluminium plate with the inner turned edge in one step without an additional cylinder is provided.

Description

Technical field [0001] The invention relates to a machine processing and shaping die equipment, in particular to an aluminum plate punching machine. Background technique [0002] Stamping is a forming method that relies on presses and molds to apply external force to plates, strips, pipes and profiles to cause plastic deformation or separation, so as to obtain the required shape and size of the workpiece (stamping). Many aluminum products are made by stamping. For some products that require flanging, such as the door trim of a car, a certain flanging is required on the outer edge to connect with other components. [0003] However, the existing mechanical processing technology can only perform one-step forming processing on stamping products with outer flanges, such as directly setting the upper and lower molds to the corresponding profile, and there is no difficulty in blocking or processing; For stamping products with inner flanging, the upper mold or lower mold cannot be directl...

Problems solved by technology

This method requires multiple cylinders in different directions (up and down and left and right directions) to cooperate, and it needs to be carried out step by step. The consumables are time-consuming, the production efficiency is low, and the production cost is high.
