A fully automatic seaming device

Abstract

The invention relates to a full-automatic seam buckling device. The full-automatic seam buckling device comprises an upper mold mechanism, a lower mold mechanism, a left push mechanism, a right push mechanism, core molds and a control system. An upper mold of the upper mold mechanism and a lower mold of the lower mold mechanism are oppositely arranged and driven by corresponding hydraulic cylinders to bend edges of a workpiece. The left push mechanism and the right push mechanism are oppositely arranged on the two sides of a mold combining position and driven by the corresponding hydraulic cylinders to bend the edges of the workpiece again. The upper mold and the lower mold are each of a split structure, and the shape of the split position of the upper mold and the lower mold is matched with the shape of the core molds arranged in the upper mold and the lower mold. The shape of the core molds is matched with the shape of the workpiece. The upper mold mechanism, the lower mold mechanism, the left push mechanism and the right push mechanism can be controlled by the control system to achieve sequential actions. According to the full-automatic seam buckling device, seam buckling machining can be achieved on longitudinal closed seams of a special-shaped sheet metal part, and machining of workpieces in different shapes can be finished after the core molds are replaced; and the automation degree of the full-automatic seam buckling device is high, the appearance quality of a finished product is good, the one-time molding rate is high, the machining efficiency can be greatly improved, and the machining cost is reduced.

Description

technical field [0001] The invention relates to the technical field of sheet metal joints, in particular to a fully automatic buckle seam device for jointing the edges of special-shaped metal sheet shells. Background technique [0002] Most of the workpieces are made of thin metal plates, which have the characteristics of light weight, high strength and rigidity, complex shapes, low material consumption, no need for machining, and smooth surfaces. They are widely used in daily life and industrial production. The workpieces can be connected by seam connection, rivet connection, welding, etc., wherein the seam connection is to bend and bite the edges of two sheets (or both sides of a piece of material) and press them against each other, and its production cost is low. [0003] The bite form of the longitudinal closed seam of the workpiece is mainly a single flat bite, which is mainly divided into manual bite and mechanical bite. On the steel, the bending line of the buckle se...

Problems solved by technology

[0003] The bite form of the longitudinal closed seam of the workpiece is mainly a single flat bite, which is mainly divided into manual bite and mechanical bite. On the steel, the bending line of the buckle seam is aligned with the edge of the channel steel for manual operation. Make the sheet material pass through multiple pairs of rotating rollers with different groove shapes, so that the bending of the sheet edge changes from small to large, step by step, and gradually formed. They can complete square, rectangular, round pipes and elbows, tees, and reducing pipes. The bite shape is formed, and the appearance quality of the bite is good, and the production efficiency is high; but for workpieces with irregular changing curves along the axial direction, the existing mechanical bite machine cannot be used for processing

At present, the buckle seam processing of this kind of special-shaped workpiece mainly adopts argon arc welding method, which is prone to deformation after welding, and the appearance quality is poor, and the proportion of defective products in the finished product is relatively high
