Abstract

The utility model discloses a U-shaped plate bending mold; and the U-shaped plate bending mold comprises an upper mold and a lower mold, wherein the upper mold is an approximately rectangular body structure, which is formed by fixing a plurality of mold sheets with same types in parallel; the lower mold is that two mold blocks are fixed at the upper end of the base in parallel; and a groove is formed between the two mold blocks. Two side edges of each mold sheet of the upper mold are inclined inwards, so as to form a wedge-shaped structure, wherein the width of the lower part of the wedge-shaped structure is larger than that of the upper part of the wedge-shaped structure. Welding grooves are respectively formed in the two side edges of each mold sheet and reinforcing ribs are welded in the welding grooves. According to the utility model, the traditional machine type bending mold is improved, each mold sheet on the upper mold is cut through a laser cutter, a shaping mold for making a workpiece is welded and the dimension accuracy of the workpiece is guaranteed. As the two side edges of the upper mold are slightly inclined to form the wedge-shaped structure, a problem of elastic reduction of the bent workpiece can be overcome and the bending production efficiency is increased.

Description

U-shaped plate bend forming die

Technical field

The utility model relates to the sheet metal bending mould in the field of machining, is specifically related to a kind of U-shaped plate bend forming die.

Background technology

Bending for sheet metal, the working condition of legacy equipment is to process at lathe, the operating process more complicated, the degree of depth and the sheet metal thickness that need given bed die total height and bed die flex area inside groove, drift falls to contacting with sheet material, then continues the angle of bend that a predetermined altitude reaches to be needed that descends.In numerical control bender, the falling head of drift is carried out mathematical computations according to the more predefined parameters of operator, then, machine is set in advance, to realize the angle of bend of sequencing.As seen operating process is very complicated, and accumulated error is large, and the bending result is not best, because such technology, the angle that many times can make acquisition often needs again to revise with error, has increased production technology, thereby increases cost.

The utility model content

The utility model provides a kind of U-shaped plate bend forming die for defective and deficiency that existing bending equipment exists.

Technical scheme: a kind of U-shaped plate bend forming die, comprise mold and bed die, the approximate rectangular body structure that described mold fixedly is made of side by side the die blade of a plurality of same model, described bed die are to fix side by side two mould pieces in the base upper end, form groove between the two mould pieces; Movable mold cooperates with the bed die groove of fixing.

Each die blade dual-side of described mold slopes inwardly, and forms lower width greater than the wedge structure on top.

Be respectively arranged with two above weld grooves on each die blade dual-side of described mold, each die blade side weld groove height that alignment is arranged is consistent, forms the combination weld groove, and solid welding has reinforcement in the combination weld groove.

Two mould pieces of described bed die are symmetrical fixing two D type structures, and the cambered surface of two D mould pieces is inside.

Beneficial effect: the utility model has improved traditional machine tool type Bending Mould, by each die blade of laser cutting machine cutting mold, and the shaping mould of welding production workpiece, the dimensional accuracy of assurance workpiece.The dual-side of mold is formed slopely wedge structure slightly, can overcome the problem of the elastic restoration of bending workpieces, reaches one-time formed characteristics, has improved the production efficiency of bending and forming.Highly versatile, the trouble of reduction factory frequent Bending Mould reduces labour intensity.Simultaneously, because purchasing and maintenance cost of equipment also further compressed in the minimizing of the supporting Bending Mould specification of bender.
