Specific embodiment
As shown in Fig. 1,2,3 and 4, a kind of riveting tool of self-clinching nut, including cushion block 1, the formed punch 2 that presses, base 3 and punching
Head driver 4, formed punch driver 4 are cylinder, and formed punch driver 4 and cushion block 1 are mounted on base 3, and the formed punch 2 that presses is mounted on punching
On head driver 4, the formed punch 2 that presses is located at the top of cushion block 1, and the driving of formed punch driver 4 presses formed punch 2 to the pushing of cushion block 1, carries out
It presses, there is the guide pin 5 of protrusion on the upper surface of cushion block 1.
Guide pin 5 divides for two sections, and the diameter of the upper section of guide pin 5 is less than the diameter of lower section, in the upper end of guide pin 5
Step surface is formed between lower end, the diameter of the threaded hole of the diameter and self-clinching nut 6 of the upper section of guide pin 5 is adapted, is used for
Self-clinching nut 6 is oriented to, the diameter in the hole that presses on the diameter of the lower section of guide pin 5 and workpiece 7 to be pressed is adapted, and is used
It is positioned in treating the workpiece 7 that presses.
The step surface of guide pin 5 is greater than the pressure of self-clinching nut 6 to the distance between contact surface H1 that presses of workpiece 7 to be pressed
Riveting depth generates when will not be due to pressing between self-clinching nut and the step surface of guide pin and squeezes and influence the quality to press.
The top surface of positioning pin is lower than the highest face after self-clinching nut 6 presses, and formed punch is pressed onto positioning when effectively preventing pressing
It sells and self-clinching nut cannot be made to be fully engaged against with workpiece.
Guide pin 5 is detachably mounted on cushion block 1.Product to be pressed is replaced every time, only needs to change guide pin 5 i.e.
Can, be conducive to 5 standardized production of guide pin.Specific detachable mounting structure are as follows: the top of cushion block 1 has mounting hole, installation
There is screw thread, the lower section of positioning pin extends downwardly out one section of thread segment, and it is fixed to have between the end of thread and the lower section of positioning pin in hole
Position step, positioning pin are detachably arranged on cushion block 1 by way of being screwed into mounting hole.
Cushion block 1 is detachably arranged on base 3.Specific detachable mounting structure are as follows: there is mounting hole on base 3,
There is screw thread, the lower end of cushion block 1 has thread segment, and the top of the end of thread has positioning step, and positioning step is by padding in mounting hole
Flange collar on block 1 is formed, and cushion block 1 is detachably arranged on base 3 by way of being screwed into mounting hole.
Operating process is as follows: first covering in the hole that presses of workpiece 7 to be pressed on the guide pin 5 on cushion block 1, then the spiral shell that will press
The threaded hole of mother 6 is inserted on the guide pin 5 of cushion block 1, following Fig. 3, since the guide pin 5 on cushion block 1 has automatic positioning function,
When formed punch driver 4 drives the formed punch 2 that presses to move downward, the formed punch 2 that presses applies pressure to self-clinching nut 6, self-clinching nut 6
Stitching surface is slid into automatically in the hole that presses of workpiece 7 to be pressed, and completes to press.
