Abstract
The utility model relates to a punching die structure, in particular to a bending swinging block structure of a punching die. The bending swinging block structure comprises an upper die and a lower die, wherein the lower die comprises a workpiece placing position, one or a plurality of swinging blocks are arranged corresponding to a to-be-bent position of a workpiece, an inner arc surface for bending and forming is formed on each swinging block, the swinging blocks are movably connected onto the upper die through a rotating shaft and droop naturally, and a limiting structure for driving the swinging blocks to be firmly pressed on the workpeice so as to bend the workpiece is arranged on the lower die. When the upper die of the bending swinging block structure of the punching die is downward pressed, the swinging blocks are driven to move toward the workpiece placing position by the limiting structure, the inner arc surfaces are matched with the workpiece placing position to achieve the round angle bending process, and the swinging blocks bend the workpiece from a loosed state to a tight state along with descending of the swinging blocks, so that bend generated on the workpiece is good in stability, and tolerance is small.
Description
Technical field
The utility model relates to a kind of stamping die structure, especially a kind of stamping die bending centering block structure.
Background technology
In stamping die, having a kind of is the Bending Mould that workpiece is carried out the fillet bending, when utilizing mould that sheet metal is carried out the fillet bending, because the screen resilience of material, when the preset angles of the mould of product is certain angle, the fillet angle of the product that often obtains after machining is greater than this preset angles, influenced the precision of product processing, especially when a plurality of fillet bending is arranged on the product, because tolerance stack, cause the precision difference of product very big easily, when serious even influence the assembling of product.
Summary of the invention
The utility model provides a kind of stamping die bending centering block structure that can effectively keep the stability of workpiece fillet bending part.
To achieve these goals, the utility model adopts following technical scheme:
It comprises upper die and lower die, comprise workpiece placement position on the described counterdie, corresponding workpiece treats that bending part arranges one or more centering blocks, centering block is provided with the intrados for bending and molding, described centering block is movably connected on the patrix by a rotating shaft and hangs naturally, and counterdie is provided with and drives centering block to the position limiting structure of Work-sheet pressing bending.
Preferably, described position limiting structure is a block, and the contact-making surface of this block and centering block is an inclined-plane, and the contact-making surface on described centering block and block inclined-plane is globoidal structure.
Owing to adopted said structure, when stamping die bending centering block structure patrix of the present utility model presses down, centering block is subjected to the driving of position limiting structure moving to workpiece placement displacement, described intrados is placed the position with workpiece and is cooperated realization fillet bending operation, and along with the decline of centering block, centering block carries out by pine to tight bending process workpiece, the good stability that makes the bending that produces on the workpiece, and tolerance is little.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Among the figure: patrix 1, counterdie 2, workpiece are placed position 3, centering block 4, intrados 41, rotating shaft 5, block 6, inclined-plane 61, globoidal structure 41.
The specific embodiment
As shown in Figure 1, the stamping die bending centering block structure of present embodiment comprises patrix 1 and counterdie 2, comprise workpiece placement position 3 on the described counterdie 2, corresponding workpiece treats that bending part arranges one or more centering blocks 4, centering block 4 is provided with the intrados 41 for bending and molding, described centering block 4 is movably connected on the patrix 1 by a rotating shaft 5 and hangs naturally, and counterdie 2 is provided with and drives centering block to the position limiting structure of Work-sheet pressing bending.Among this city embodiment, shown in workpiece be positioned at workpiece and place both sides, position and all need bending, so corresponding each workpiece placement position arranges two centering blocks and simultaneously the bending of two places is processed, a plurality of workpiece arranged side by side also can be set on the counterdie as shown in FIG. place the position, to realize that a plurality of workpiece are carried out Bending Processing simultaneously.
For simple in structure, and realize position limiting structure to the driving of centering block by the downforce of patrix, in the present embodiment, described position limiting structure is a block 6, this block 6 is an inclined-plane 61 with the contact-making surface of centering block 4, and described centering block 4 is globoidal structure 41 with the contact-making surface on block inclined-plane 61.
During work, patrix 1 presses down, and when the inclined-plane 61 of globoidal structure 41 contact blocks 6 of centering block 4, centering block 4 is swung along rotating shaft 5, and then moves and compress gradually to the workpiece direction, thereby finishes bending operation.
The above only is preferred embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
