Abstract
The utility model relates to a sectional type arc bending forming tool comprising an upper tool and a lower tool, wherein the upper tool is formed in the way that an upper arc bending element is fixed on an upper supporting plate; the lower tool comprises a lower supporting plate which is provided with a sectional type movable lower arc bending component; an elastic compression resisting element is arranged between the lower arc bending element and the lower supporting plate; and the lower arc bending element is arranged in an umbrella shape from the middle to two ends. With the sectional type arc bending forming tool, the bending of a larger product can be realized in a sectional type on a smaller pressure machine, so that the cost on a large pressure device is saved, the waste on a disposable special machine is reduced, the development cycle is shortened, and the production cost is reduced, and the quality guarantee is enhanced.
Description
Technical field
The utility model relates to a kind of curved arc shaping frock, especially relates to a kind of segmented curved arc shaping frock that can the segmentation bending forming.
Background technology
At present knownly be mainly drawing and forming or utilize the special plane moulding at the hardware products bending forming, when wherein adopting drawing and forming, be easy to generate bad product of quality and the special-purpose expanded material of need and need bigger forcing press, and Production Time is long, difficulty is big, cost is higher, if use the special plane moulding, versatility is not strong, and input cost is bigger, therefore be unfavorable for the factory cost management and control, cause the wasting of resources bigger.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of segmented curved arc shaping frock, and it can be implemented in one than the curved arc moulding process of finishing big product on the subpress, to save construction cycle and production cost.
The technical scheme in the invention for solving the technical problem is: a kind of segmented curved arc shaping frock, comprise frock and following frock, last frock is fixed on top deck by last curved arc element and forms, described frock down comprises bottom deck, curved arc assembly under the segmented activity is set on the bottom deck, be provided with elasticity resistance to compression element between curved arc assembly and the bottom deck down, following curved arc assembly is umbrella shape and arranges from the centre to two ends.
In order to realize the segmentation bending of raw material, in the described curved arc assembly down movable following curved arc element at least one; The described following curved arc element of curved arc assembly edge down is fixedly connected on the bottom deck.
For last bender element is positioned and fixes, be provided with block around the described upward curved arc element, last block is fixed on the top deck.
Spacing in order to carry out to the following curved arc element of activity, be respectively equipped with down positive stop and following backstop before and after the described curved arc assembly down, bed hedgehopping piece under a side of backstop is provided with down, following bed hedgehopping piece is provided with down by piece.
The beneficial effects of the utility model are: can be shaped than the bending of big product with multisection type simultaneously on a less forcing press, large-scale press device input or the disposable waste of special plane have been saved, and saved construction cycle and cost of manufacture, improved the quality guarantee.

The specific embodiment
Further specify below in conjunction with drawings and Examples.
A kind of as shown in Figure 1 segmented curved arc shaping frock, comprise frock and following frock, last frock is fixed on top deck 1 by last curved arc element 2 and forms, described frock down comprises bottom deck 3, curved arc assembly under the segmented activity is set on the bottom deck 3, be provided with elasticity resistance to compression element between curved arc assembly and the bottom deck down, following curved arc assembly is umbrella shape and arranges from the centre to two ends; Movable following curved arc element comprises curved arc element I 4, following curved arc element II 5 and following curved arc element III 6 down in the described curved arc assembly down; The described following curved arc element IV 7 of curved arc assembly edge down is fixedly connected on the bottom deck 3.
Be provided with link stopper I 12 around the described as shown in Figure 2 upward curved arc element 2, go up link stopper II 13 and last link stopper III 14, and be fixed on the top deck 1; Be respectively equipped with down positive stop 18 and following backstop 17 before and after the described curved arc assembly down, bed hedgehopping piece 16 under a side of backstop 17 is provided with down, following bed hedgehopping piece 16 is provided with down by piece 15.
The segmented curved arc shaping frock course of work is at first by last curved arc element 2 curved arc element I 4 under the central point contact of former material 20 (as shown in Figure 3) to be carried out first section cambered surface moulding in the descending process of forcing press; Elasticity resistance to compression element I 9 is and then descending behind pressurized in the descending process of forcing press continuation, goes up curved arc element 2 after curved arc element I 4 goes downwards to a certain degree instantly and touches down second section cambered surface of curved arc element II 5 moulding; Continue to keep under the downstream state elasticity resistance to compression element I 9 and elasticity resistance to compression element II 10 descending equal height and to follow forcing press descending behind pressurized at forcing press; The 3rd section cambered surface of moulding when curved arc element 2 contacts with following curved arc element III 6 on coming downwards to, it is lasting descending that elasticity resistance to compression element I 9, elasticity resistance to compression element II 10 and elasticity resistance to compression element III 11 descending equal height of while behind pressurized also keeps following forcing press under the lasting maintenance of the forcing press downstream state; Shaping final stage cambered surface when curved arc element 2 contacts with following curved arc element IV 4 on coming downwards to, forcing press walks to bottom dead centre, and have suffered forming process and finish this moment.
