Below introduce the operation principle of retainer rivet insertion device provided by the invention.
Retainer rivet insertion device provided by the invention, comprise drift bolt patrix 1, inclined hole mould assembly 2 and drift bolt counterdie 3, the upper end of drift bolt patrix 1 is connected with the clutch end of the power spare that can pump, and the lower end of drift bolt patrix 1 is provided with the pressure nail pin 11 that quantity is no less than; Inclined hole mould assembly 2 be arranged on drift bolt patrix 1 under, the lower end of inclined hole mould assembly 2 is provided with springform 23, springform 23 is provided with and the corresponding through hole 24 in drift bolt hole that need carry out the retainer of drift bolt, and through hole 24 is corresponding at vertical direction with the pressure nail pin 11 of drift bolt patrix 1 lower end, the side that inclined hole is touched assembly 2 also is provided with quantity and is no less than an inclined hole mould pipe 25, inclined hole mould pipe 25 is skewed setting, and its lower end is corresponding with the upper end of through hole 24; Drift bolt counterdie 3 be arranged on inclined hole mould assembly 2 under.
The retainer that needs are carried out drift bolt is placed on the upper surface of drift bolt counterdie 3, the drift bolt hole of retainer is aimed at one by one with through hole 24, rivet is put in the inclined hole mould pipe 25, the tip of assurance rivet down, rivet is in inclined hole mould pipe 25 enters the through hole 24 of springform 23, and rivet will be in the through hole 24 that vertical shape is stuck in springform 23, and nail hole patrix 1 moves downward, the upper end that the pressure nail pin 11 of nail patrix 1 lower end, hole withstands rivet is pressed into rivet in the drift bolt hole of retainer; Drift bolt patrix 1 moves upward, and retainer separates with springform 23, and the retainer that passes rivet is taken out, and puts into the retainer that the next one needs drift bolt again, repeats above-mentioned steps.Can be provided with a plurality of on the springform 23 of the retainer rivet insertion device of this structure and the corresponding through hole 24 in drift bolt hole retainer, simultaneously, drift bolt patrix 1 is provided with the pressure nail pin 11 identical with through hole 24 quantity, and the side of inclined hole mould assembly 2 is provided with and the identical inclined hole mould pipe 25 of institute's through hole 24 quantity.Like this, all be pressed into rivet in drift bolt hole that once can retainer is all, the efficient height, and save manpower, can reduce production costs.
In the preferred version, after drift bolt patrix 1 is pressed into rivet the drift bolt hole of retainer, when moving upward, in order to prevent that retainer is bonded in the springform 23, move upward with springform 23, in springform 23, be provided with springform material returned pin 27, one end of springform material returned pin 27 is fixing with inclined hole mould assembly 2 by material returned needle spring 28, and the other end is positioned at the groove 26 of springform 23 lower ends.When springform 23 and retainer compress, springform material returned pin 27 retainer under the effect of power, compression material returned needle spring 28, make the lower end of springform material returned pin 27 be retracted in the springform 23, when springform 23 is separated with drift bolt counterdie 3, reducing rapidly between springform 23 and the retainer against power, under the effect of material returned needle spring 28, the lower end of springform material returned pin 27 produces a thrust to retainer, make retainer separate, so just can avoid retainer and springform to stick together with springform.
After drift bolt patrix 1 was pressed into the drift bolt hole of retainer with rivet, the lower end of rivet also was inserted in the nail hole on the drift bolt counterdie 3, if adopt manually retainer was taken out from drift bolt counterdie 3, because the application of force is unbalanced, caused the retainer distortion easily.
In order to solve the problems of the technologies described above, below drift bolt counterdie 3, be provided with counterdie backing plate 4, be provided with counterdie material returned dish 41 in the cavity of counterdie backing plate 4 upper surfaces, the lower surface of counterdie material returned dish 41 is connected with counterdie backing plate 4 by material returned dish spring 43, the upper surface of counterdie material returned dish 41 is provided with the counterdie material returned pin 42 that quantity is no less than, the upper end of counterdie material returned pin 42 can be inserted in the nail hole 31 on the drift bolt counterdie 3, in the preferred version, the quantity of counterdie material returned pin 42 is identical with the quantity in nail hole 31, all is inserted with a counterdie material returned pin 42 in 31 in each nail hole.
When being pressed into rivet in the drift bolt hole of retainer, the lower end of rivet will be against the upper end of counterdie material returned pin 42, and rivet will produce a pressure to counterdie material returned pin 42, and under the effect of this pressure, counterdie material returned dish 41 will compress material returned dish spring 43 and move downward; Inclined hole mould assembly 2 is with after separate the upper surface of drift bolt counterdie 3, rivet reduces rapidly the pressure of counterdie material returned pin 42, material returned dish spring 43 begins to reset, promoting counterdie material returned dish 41 moves upward, counterdie material returned pin 42 on the counterdie material returned dish 41 ejects nail hole 31 with rivet, rivet will drive retainer and move upward together, until the upper surface that breaks away from drift bolt counterdie 3.Counterdie material returned pin 42 on the counterdie material returned dish 41 is simultaneously to the rivet effect on the retainer, and retainer is stressed evenly, and retainer can break away from drift bolt counterdie 3 under indeformable situation.
The above only is the description of preferred implementation of the present invention; should be understood that; because the finiteness of literal expression; and objectively have unlimited concrete structure; for those skilled in the art; under the prerequisite that does not break away from the principle of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
