Abstract
The utility model discloses an upper mould used for a power riveting machine. The upper mould comprises a mould body and a mould shank positioned on the upper surface of the mould body, wherein a cylindrical concave part is arranged at the top end of the mould shank; a fixed plate is fixed on the mould body through four embedded hexagon bolts, and is positioned below the mould body; a riveting piece is connected to one side corresponding to the fixed plate; a pressing bar is vertically arranged in the middles of the mould body and the mould shank in a penetrating manner; threads are formed in the pressing bar, and nuts are arranged at the top end of the pressing bar and are positioned in the concave part; a pressing cap is arranged at the lower end of the pressing bar; a compression spring is arranged between the pressing cap and the fixed plate. According to the utility model, the pressing bar is pre-pressed at the center position of a workpiece, so that the stability of the pressed workpiece can be guaranteed; through the adoption of the compression spring, the pre-pressure can be reduced, and the fact that cracks caused by extrusion on the workpiece are avoided is ensured; through the adoption of the compression spring, the pre-pressing height can easily exceeds the height of the workpiece, the cutting scrap phenomenon of the workpiece is avoided, and the service life of the mould is greatly prolonged.
Description
Technical field
The utility model relates to a kind of mold for power riveting machine.
Background technology
In prior art, adopt rubber to carry out pre-pressure discharge always, because the height of product is higher, the height of precompressed rubber also requires to increase, make rubber produce afterwards very large pressure in compression, after easily making workpiece (nylon 66) be subject to squeeze, cracking is scrapped, if adopt rubber hollow out, can reduce the pressure that rubber produces afterwards in compression, but cannot ensure the service life of rubber.If reduce the height of precompressed rubber, also can reduce the pressure that rubber produces afterwards in compression, scrapped by mould cutting but easily produce workpiece.A kind of improvement project is now provided.
Utility model content
The purpose of this utility model is to provide a kind of mold for power riveting machine.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of mold for power riveting machine, comprise die ontology and be positioned at the die shank of die ontology upper surface, die shank top has cylindrical depression portion, die ontology is by the fixing fixed head of four embedded hex bolts, fixed head is positioned at die ontology below, the corresponding side of described fixed head is connected with riveting parts, described die ontology be equipped with stock pressing rod vertical with die shank medium position, stock pressing rod top is provided with screw thread, top is provided with nut, nut is positioned at depressed part, and stock pressing rod lower end is provided with pressure-pad, between pressure-pad and fixed head, is provided with Compress Spring.
The beneficial effects of the utility model: the utility model adopts stock pressing rod to be pressed in advance workpiece centre position, can ensure after workpiece pressurized steadily, adopt Compress Spring, can reduce precompression, guarantee that workpiece can not crack because of extruding.Adopt Compress Spring, precompressed highly can exceed the oneself height of workpiece easily, and workpiece can not produce to be cut scraps phenomenon, and die life increases substantially.
Brief description of the drawings
For the ease of it will be appreciated by those skilled in the art that below in conjunction with accompanying drawing, the utility model is further described.
Fig. 1 is the utility model schematic side view.
Fig. 2 is the utility model front elevational schematic.
Detailed description of the invention
As depicted in figs. 1 and 2, a kind of mold for power riveting machine, comprise die ontology 1 and be positioned at the die shank 2 of die ontology 1 upper surface, die shank 2 tops have cylindrical depression portion 3, die ontology 1 is by four embedded fixing fixed heads 6 of hex bolts 9, fixed head 6 is positioned at die ontology 1 below, the corresponding side of described fixed head 6 is connected with mold blade 7, described die ontology 1 be equipped with stock pressing rod 4 vertical with die shank 2 medium positions, stock pressing rod 4 tops are provided with screw thread, top is provided with nut 5, nut 5 is positioned at depressed part 3, stock pressing rod 4 lower ends are provided with pressure-pad 10, between pressure-pad 10 and fixed head 6, be provided with Compress Spring 8.
Working method: workpiece and base assembly are placed on bed die locating piece, the utility model mold declines, pressure-pad 10 is first pressed in the centre of workpiece in advance, along with reducing of die shut height, stock pressing rod 4 is pushed, and Compress Spring 8 is compressed, workpiece is positioned on counterdie locating piece tightly, in the time that mold position drops to minimum point, mold blade 7 moves with workpiece, and workpiece both sides root is pushed at 45 ° and pedestal (nylon 66) tightly together with riveting by blade 7.Mould resets, EO.
Above content is only to the utility model structure example and explanation; affiliated those skilled in the art make various amendments to described specific embodiment or supplement or adopt similar mode to substitute; only otherwise depart from the structure of utility model or surmount this scope as defined in the claims, all should belong to protection domain of the present utility model.
