Abstract

The utility model discloses a riveting die, which comprises an upper die holder, a lower die holder and a die body. The die body includes punches and dies, a floating plate is arranged on the lower die holder and elastically connected with the lower die holder, each punch is connected with one wedge slider, a wedge slider driving block matched with the wedge slider is fixedly mounted on the lower die holder and below the corresponding wedge slider, one punch and the corresponding wedge slider are disposed on one fixed plate fixed on the floating plate, each die is fixed to one side of one slider which is mounted in a pressure plate and capable of sliding in the pressure plate, and each elastic ejector pin is mounted on the upper die holder and right above the corresponding slider. No pneumohydraulic pressure cylinder is added to the riveting die to serve as special equipment for providing driving force, and thereby structural riveting can be achieved synchronously on a product forming die, production procedures are decreased, production efficiency is improved, and product cost is reduced.

Description

A kind of riveted joint mould
Technical field
The utility model relates to a kind of sheet metal component riveting mechanism, relates in particular to a kind of riveted joint mould.
Background technology
At present, the sheet metal structural spare connected mode of household electrical appliance such as washing machine protecgulum mostly is the riveted joint mode, because of the restriction of riveting process to the material flowing velocity, method in common all uses pneumohydraulic pressure-cylinder to provide the riveted joint driving force to satisfy riveting process, the result will realize the simple connection of product structure, need make complicated special equipment and realize, the equipment input cost of causing is big, production process increases, production efficiency is slow, turnover scrappage height, drawbacks such as product cost lifting.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of riveted joint mould, make implementation structure riveted joint synchronously on the formed product mould, do not increase in addition and use pneumohydraulic pressure-cylinder that the special plane equipment of driving force is provided, thereby reduced production process, improve production efficiency, reduced production cost.
Riveted joint mould of the present utility model comprises upper bolster, die shoe and die main body, and described die main body comprises punch and die, is provided with float plate on described die shoe, and float plate is connected with die shoe elasticity; Described punch is connected with the wedge slide block, is installed with the wedge drive block that matches with the wedge slide block on the die shoe below the wedge slide block, and described punch and wedge slide block place the fixed head that is fixed on the float plate; Described die is fixed on slide block one side, and described slide block is installed in the holding pad and can slides in holding pad, and the elasticity ejector pin is installed on the upper bolster directly over the described slide block.
Be provided with wearing plate between described fixed head and float plate, the bottom of described wedge slide block is slidingly connected mutually with wearing plate on being fixed on die shoe.
Described wedge drive block connects a stop block that is fixed on the die shoe, is used to prevent behind the wedge lateral force to cause the riveted joint stroke not in place along be offset by force direction, and empty riveting phenomenon appears in product.
Described upper bolster and die shoe are provided with limited post, and the position that is used for matched moulds limits, and make shaping, riveted joint finish the back mold stroke synchronously and stop just, guarantee that the riveted joint base material thickness is uniform and stable not puncture and guarantee to rivet concentricity protruding, die.
Riveted joint mould of the present utility model, other increases the special plane equipment that uses the pneumohydraulic pressure-cylinder conduct that driving force is provided, and can rivet by synchronous implementation structure on the formed product mould, has reduced production process, has improved production efficiency, has reduced production cost.
Description of drawings
Accompanying drawing is a riveted joint mould structure schematic diagram of the present utility model.
Among the figure: 1, upper bolster; 2, limited post; 3, wearing plate; 4, die shoe; 5, stop block; 6, wedge drive block; 7, wedge slide block; 8, fixed head; 9, punch; 10, die; 11, elasticity ejector pin; 12, slide block; 13, holding pad; 14, float plate.
The specific embodiment
As shown in drawings, riveted joint mould of the present utility model, comprise upper bolster 1, die shoe 4, punch 9 and die 10, wherein upper bolster 1 and die shoe 4 are provided with limited post 2, make shaping, riveted joint finish the back mold stroke synchronously and stop just, guarantee that the riveted joint base material thickness is uniform and stable and do not puncture and guarantee to rivet concentricity protruding, die; On described die shoe 4, be provided with float plate 14, and float plate 14 and die shoe 4 are connected by spring; Described punch 9 is connected with wedge slide block 7, on the die shoe below the wedge slide block 74, be installed with the wedge drive block 6 that matches with wedge slide block 7, described wedge drive block 6 connects a stop block 5 that is fixed on the die shoe, stop block embeds in the die holder, the edge is offset by force direction after effectively preventing the wedge lateral force, cause the riveted joint stroke not in place, empty riveting phenomenon appears in product; Described punch 9 and wedge slide block 7 place the fixed head 8 that is fixed on the float plate 14, are provided with wearing plate 3 between fixed head 8 and float plate 14, and the bottom of described wedge slide block 7 is slidingly connected mutually with wearing plate 3 on being fixed on die shoe; Described die 10 is fixed on slide block 12 1 sides, and described slide block 12 is installed in the holding pad 13 and can slides in holding pad along guide rail, on the upper bolster 1 directly over the described slide block 12 elasticity ejector pin 11 is installed, and it touches mutually with slide block 12, is used to play top sliding block 12.
Riveted joint mould of the present utility model in use, manually put into workpiece to mold cavity, with product orientation in mould, start press, patrix comes downwards to holding pad and contacts with workpiece, slide block was stressed upon in the holding pad and slided obliquely along guide rail this moment, thereby can snap in the back-off structure of workpiece product, patrix continues descending, because the elastic reaction float plate is descending, drives the wedge slide block down simultaneously, be subjected to the effect of wedge drive block, the wedge slide block drives punch motion punching press, and when matched moulds was finished, riveted joint was finished, patrix is up, slide block is in the oblique lower slider of the promotion lower edge of elasticity ejector pin guide rail, thereby broken away from the back-off structure of workpiece product, and float plate is recovered stroke under the promotion of compression spring, it is up to drive the wedge slide block simultaneously, punch withdraws from, and the riveted joint slide block assembly retreats to the home position, shaping under the driving of retracting spring, the riveted joint recombination process is finished a complete work period.The utility model is compared with conventional art, save infusion of financial resources and make special equipment, do not increase the molding procedure that product structure is realized, in formed in mould process, realized the riveted structure of product synchronously, fully ensure the desired consistency of effect, significantly reduce cost of goods manufactured and effectively enhance productivity.
