Abstract
The invention relates to a combined bending and forming process. A main pressure die is used for bending a U-shaped slot; an upper die returns; an ejector rod of a lower die can push the plate material out of the U-shaped slot; after continuous operation, the lower die body is pushed to exchange position under the action of a position-exchanging oil cylinder; the feeding distance is controlled by a material baffle device of the bending machine; the machining precision of each slot is ensured; the position exchange can be realized conveniently; the process can be simplified effectively; and the cost can be reduced.
Description
Technical field
The present invention relates to metal bending technology, particularly use combination bender moulding process.
Background technology
Metal bending material is widely used in industries such as building, machinery, electronics, its product forming process is common in row's roller rolling formation, the product of simple shape also can be finished on bender, and the product of complicated shape bending and forming on bender is uncommon, because the restriction of equipment shortage or product specifications vary or the like factor, bending and forming is produced difficulty in batches, and the production cycle is long, has improved the technology cost.
Summary of the invention
In order to solve above-mentioned drawback, the invention provides a kind of combination bending forming technology, comprise: finish the order bending and the compacting of each U type groove, realize unidirectional flanging and in the V-type groove, finish the right-angle side moulding, it is characterized in that, main pressing mold is finished the bending compacting of first U-lag of bus duct, the patrix return, the counterdie knock-pin ejects plate, and plate enters second station, the combination patrix is descending, secondary pressing mold at first presses down the flanging of realization to plate, and it is unidirectional mobile to control its plate, then, main pressing mold is finished the shaping of second U-lag once more, and plate enters the bending and forming that next station is finished each U-lag successively.Then, the transposition cylinder action promotes the lower mold body transposition, the lower mold body V-shaped groove is in the operating position, at this moment, the secondary pressure head of combination patrix resets under action of reset spring, the bending and forming of each right-angle side of product order in V-shaped groove is finished, and the distance of sending to of plate is controlled by the bender stock stop in the product forming process.

The specific embodiment
The product forming process can be divided into 10 work steps, as shown in Figure 1 ((1)～(10) are product forming process step).At first, finish the order bending and the compacting of each U-lag, the displacement and the error of U-lag both sides generation plate will have a strong impact on the part accuracy requirement in this forming process, therefore, in the U-lag bending and forming process, realize that its unidirectional flanging is very necessary.Progressively finish the bending and forming of each right-angle side then, and the shaping of each right-angle side need be finished in V-shaped groove.For this reason, we have manufactured and designed the combination bender to finish the bending and forming to each work step of product.
As shown in Figure 2.The combination patrix mainly comprises main pressing mold 1, secondary pressing mold 4, and back-moving spring 9 reaches several parts such as prefabricating oil cylinder 2.Secondary pressing mold 4 is installed in main pressing mold 1 guide groove, is realized sliding up and down by back-moving spring 9 and prefabricating oil cylinder 2 effects, and the installation form of patrix on bender is identical with the installation form of common Bending Mould.Counterdie mainly comprises lower mold body 5, knock-pin 6, back-moving spring 9, transposition plunger case 13, parts such as transposition pedestal 7.In like manner, the installation of counterdie inversion mechanism on the bender workbench is identical with the installation form of common bending counterdie, and lower mold body 5 removable transposition under the effect of transposition plunger case 13, its transposition precision can be regulated accurately location by backstay 12.
Fig. 2 makes up version 1 main pressing mold, 2 prefabricating oil cylinders, 3 plungers, 4 secondary pressing molds, 5 lower mold body, 6 knock-pins, 7 transposition pedestals, 8 screws, 9 back-moving springs, 10 oil-ins, 11 screws, 12 backstays, the 13 transposition plunger cases of bender; for not influencing host performance and host work parameter; realize secondary pressing mold precompressed and counterdie transposition action, the combination bender has disposed independently hydraulic system.At first, lower mold body 5 is in the diagram operating position, main pressing mold 1 is finished the bending compacting of first U-lag of bus duct, the patrix return, and counterdie knock-pin 6 ejects plate, plate enters second station, the combination patrix is descending, and secondary pressing mold 4 at first presses down the flanging of realization to plate, and it is unidirectional mobile to control its plate, then, main pressing mold 1 is finished the shaping of second U-lag once more.In like manner, plate enters the bending and forming that next station is finished each U-lag successively.Then, the transposition cylinder action promotes lower mold body 5 transpositions, and the lower mold body V-shaped groove is in the operating position, and at this moment, the secondary pressure head of combination patrix resets under action of reset spring, and the bending and forming of each right-angle side of product order in V-shaped groove is finished.The distance of sending to of plate can be by the control of bender stock stop, to guarantee part accuracy in the product forming process.Mould design main points (1) combination patrix segment design had both made things convenient for machining and heat treatment, guaranteed die quality, was convenient to the assembling and the replacing of patrix simultaneously.(2) the matched moulds gap between choose reasonable master pressing mold and secondary pressing mold and the lower mold body U-lag, the size in gap is the principal element that influences part accuracy, and the gap is big more, and part accuracy is poor more, but the too little meeting in gap causes the withdrawing pattern difficulty or make the product surface produce scratch.Here, the size in gap is determined with repairing a die by test of many times.(3) guarantee about main pressing mold two place's shoulders consistent with the height of lower mold body U-lag end face be very necessary, and, its left and right sides shoulder fillet size also can directly influence part accuracy and quality, fillet is big more or left and right sides height of shoulder is inconsistent, the flanging effect is just undesirable more, and the too little meeting of fillet makes the product surface produce big impression, we determine that the shoulder fillet is that R is (preferred in the design, R=0.5), lower mold body adopts the design of global design body, has both guaranteed each groove machining accuracy, also be convenient to realize its transposition, and, because counterdie is mounted on the bender lower table face, therefore also make things convenient for simultaneously its installation and replacing.This combination bender has not only guaranteed the specification requirement that product is shaped, and can satisfy the product bending and forming of different size or shape, simultaneously comparatively ideal effect is played in the application and the performance of its limited equipment.
The invention is not restricted to the foregoing description; in design scope of the present invention; the description of book according to the above description, those of ordinary skill in the art also can make some conspicuous changes, but these changes all should fall within the protection domain of claim of the present invention.
