Abstract
The utility model discloses a dimpling mould for a circular tube, which is characterized in that a punch (4) and a taper wedge (5) are inserted in a fixing plate (3) for the punch, and fastened by screws respectively; the fixing plate (3) is fixed on an upper mould plate (2) on which guide sleeves (6 and 6') are mounted; a slide block base (18) and guide poles (7 and 7') are mounted on a lower mould plate (10); grooves are formed on the two side surfaces of a big slide block (13) and a small slide block (12), and are pressed against the slide block base (18) by two pressure plates (14 and 14'); a pair of pull rods (8 and 8') is fixed on one side without a semi-circular hole of the small slide block (12); and a pair of pull rods (15 and 15') is fixed on the outer side of the one end with a semi-circular hole of the big slide block (13). The punch (4) is always arranged in the big and small slide blocks in dimpling to prevent the unbalanced loading after stressed and guarantee enough strength and rigidity of the punch, thereby prolonging the service life of the punch; the height of the circular tube clamped by the big and the small slide blocks (13 and 12) exceeds the two thirds of the tube diameter, so that the clamping area is large, and the stress is uniform; under the action of the taper wedge, the circular tube is not easy to loose since clamped, so that the purpose of reliable clamping is achieved; and the center of a slotted hole on the slide block faces to that of the circular tube, therefore, the punch dimples after entering a slotted hole, so that the accurate dimpling position is guaranteed and the product quality is improved.
Description
Technical field
The utility model relates to a kind of pipe towards the snap tool, is mainly used in and goes out the spill nest on circular pipe, belongs to technical field of mold.
Background technology
At pipe upper punch nest, requirement must tightly be clamped pipe, otherwise pipe can rotate when being shaped, and the kernel of section that the center of drift must the centering pipe, guarantees the positional precision towards nest.Design routinely, in order to abdicate the descending space of drift, also convenient for loading and unloading, the position height of clamping pipe can not surpass the center of pipe, and the clamping area is little like this, and dynamics is not enough, and the stressed easy unbalance loading of drift, thereby reduced the drift life-span, reduce towards the nest positional precision.
The utility model content
In view of the deficiency of above-mentioned existence, the utility model provides a kind of novel circular tube towards the snap tool, and this mould holding area is big, and reliable clamping is not easy to become flexible, and the long service life of drift is towards nest precision height.
The technical scheme that its technical problem that solves the utility model adopts is: before nest, the big small slide block that is used for held circular pipe is in initial position under spring action separately.This side of held circular pipe all has the semicircle orifice identical with the pipe exradius on the large and small slide block, and two semicircle orifices merge the back with one heart, and the center of circle is on the contact-making surface of large and small slide block.Above circular hole, have the slotted hole identical with the drift cross section, on the large and small slide block each half, slotted hole line of symmetry and round hole axial are on a vertical plane.The small slide block design is in the U type groove of big slide block, and the two sides of large and small slide block fluting is pressed against the two in the slide block base by two pressing plates, and base is fixed on the lower bolster by screw.Small slide block is the fixing a pair of pull bar of a side in open semicircle hole not, and pull bar passes a not end in open semicircle hole of big slide block, and cover one spring is fixed on spring on this end face of big slide block with nut and pad on the pull bar.Under spring action, small slide block is drawn the inboard that leans against big this end of slide block by pull bar.Big slide block has the fixing a pair of pull bar in the end outside of semicircle orifice, and pull bar passes an end of slide block base, and cover one spring on the pull bar is fixed on spring with nut and pad on the lateral surface of this end of slide block base.Under spring action, by pull bar big slide block is drawn together with the small slide block on it to lean against on the inboard face of this end of slide block base, two semicircle orifices of large and small like this slide block separate.On two lateral surfaces parallel of slide block base with the slide block movement direction, fix a location-plate respectively, U type groove is left on location-plate top, the center of arc of U type trench bottom just with big small slide block on the semicircle orifice center with high.Pipe blank frame is in the U of two location-plates type groove, and drift and support are fixed on the cope match-plate pattern by fixed head with wedge.The work beginning, the press ram (not shown) drives cope match-plate pattern and drift, wedge is descending, because wedge is longer than drift, wedge at first inserts this side of small slide block steady brace, so small slide block can be under the wedge effect with big slide block, motion simultaneously, two semicircle orifices of large and small slide block are toward drawing close together, and pipe clamps the most at last, and the effect of wedge, can not become flexible after big small slide block clamps.Half slotted hole on the big small slide block also combines thus, with back punching head insert this slotted hole to pipe towards nest.End-of-job, press ram is up, drives drift and leaves slotted hole earlier, and wedge also leaves slide block then, and large and small slide block unclamps pipe separating under the spring action separately, gets back to initial position, and at this moment the pipe behind the nest can take out.
Compared with prior art the beneficial effects of the utility model are: drift is contained in the big small slide block towards nest the time all the time, and leads therefrom, prevents the stressed unbalance loading of drift, guarantees that drift has enough strength and stiffness, has improved the life-span of drift.The height of big small slide block held circular pipe surpasses 2/3rds of pipe diameter, and the clamping area is big, and is stressed even.And because the effect of wedge, slide block clamps pipe and is difficult for becoming flexible reliable clamping.Slotted hole center on the slide block is in design and add and face the pipe center man-hour, again towards nest, has guaranteed the positional precision towards nest after drift is introduced into slotted hole, has improved the quality of product.
