Convertible welding mold

Abstract

The invention provides a convertible welding mold. The convertible welding mold comprises a mold body, overturning devices, outer clamping devices and inner clamping devices, wherein the mold body comprises side plates, an upper connecting plate and a lower connecting plate; the side plates are positioned on two sides of the mold body; the side plates are connected with each other by the upper connecting plate and the lower connecting plate; the overturning devices are arranged at two ends of the mold body; the outer clamping devices are arranged on the side plates on two sides of the welding mold; and the inner clamping devices are arranged on the upper connecting plate and the lower connecting plate. A workpiece to be welded is positioned and clamped by the inner clamping devices and the outer clamping devices of the turnover mold body, workpieces with two different crotch sizes can be continuously welded, the welding efficiency and the utilization rate of equipment are improved, the space is saved on overall arrangement of a workshop, the vacancy rate is reduced, and the welding cost is also reduced.

Description

technical field [0001] The invention relates to the technical field of welding molds, in particular to a welding mold used for welding workpieces with different opening sizes. [0002] Background technique [0003] The three-section full-free gantry of the forklift is composed of outer, middle and inner three-width gantry. The processing accuracy requirements are higher than that of the two-section gantry. Because of the small demand, there was no mold before, and its positioning and clamping are more during production. If it is done by hand, the accuracy is difficult to guarantee, and there are often rework phenomena, and the production cycle is longer. However, with the increase in the demand for three-section full-free gantry, it is imperative to make molds. Because the three-section full-free gantry includes outer, middle and inner three-piece gantry, three sets of molds need to be made correspondingly, and the production cost of the mold is high. Low efficiency and l...

[0003]The three-section full-free mast of the forklift is composed of outer, middle and inner masts. Less, there were no molds before, and the positioning and clamping were mostly done by hand during production, the accuracy is difficult to guarantee, rework often occurs, and the production cycle is longer

However, with the increase in the demand for three-section full-free gantry, it is imperative to make molds. Because the three-section full-free gantry includes outer, middle and inner three-piece gantry, three sets of molds need to be made correspondingly, and the production cost of the mold is high. Low efficiency, takes up a lot of space
