Background

At present, in the production process of many parts of automobiles, riveting equipment is needed to process workpieces. The working process of the existing riveting equipment is as follows: the riveting nut is placed in the equipment, then a workpiece is placed, the starting button is pressed by two hands to start riveting, and the nut cannot be monitored due to leakage. At present in the work piece production process, because operation personnel's fatigue degree and attention concentrate on can slowly weaken in the course of the work, can't guarantee the qualification rate of work piece output quality completely, if riveting error, lead to leaking and rivet, flow into customer assembly workshop and can cause serious quality problems, influence the automobile assembling, influence the overall performance of car even.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing safe and convenient punching press riveting leakage-proof waste discharge riveting devices for overcoming the defects of the prior art.

kinds of punching press riveting leak protection are arranged useless riveting set, including last mould and lower mould, be equipped with the mould drift on going up the mould, be equipped with the lower mould drift on the lower mould and take off the flitch, the lower mould drift on be equipped with the U type groove of placing the rivet, wait that the riveting work piece is arranged in and is taken off the flitch, its characterized in that, the inside inductor that is equipped with of lower mould drift, take off the flitch on still be equipped with the mouth of blowing, whether the inductor response U type inslot places the rivet and targets in place, is, then carry out the punching press riveting, no, then indicate the U type groove position of not placing the rivet, during the punching press return stroke, blow away the useless round pin of U type inslot through the mouth.

inductors are arranged in the lower die punch below each screw to be riveted, and each inductor is connected with an induction indicating lamp.

through holes are formed in the lower die punch and used for inserting the inductor, and the inductor is fixed through the tightening screws.

And the supporting screw is screwed into the locking inductor from the side wall of the through hole in the lower die punch.

And an air blowing channel communicated with the U-shaped groove of the mounting rivet is arranged on the stripper plate, an air blowing port at the end of the air blowing channel is aligned to the U-shaped groove, and the other end of the air blowing channel is connected with an air path system of the die.

Each U-shaped groove on the stripper plate is communicated with blowing channels, and the blowing channels are connected to the existing gas path system of the die in parallel or in series.

Compared with the prior art, the utility model discloses prevent having following advantage:

1. the sensor is added under the rivet, the sensor is arranged in the lower die punch and locked by a supporting screw, the connecting line is connected with a control system of the punching machine tool, and the detection of rivet leakage can be smoothly carried out by utilizing the control system of the punching machine tool. Utilize the inductor to detect the screw, if have to leak to put the screw phenomenon, the inductor can not detect the unable normal work of screw equipment, only detect all screw equipment and just can normally work, need not artifical full detection and reduce cost of labor, greatly increased production efficiency.

2. In order to prevent the waste pin from remaining in the riveting hole during riveting, the blowing hole is additionally formed in the stripper plate and connected with a machine tool gas circuit system, the waste pin is successfully blown away during a stamping return stroke, and the smooth work of rivet leakage induction is guaranteed.

FIG. 2 is a schematic structural view of a lower die punch of the device of the present invention;

fig. 3 is a schematic diagram of the stripping plate structure of the present invention.

Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

Examples

As shown in fig. 1-2, punching riveting leak-proof waste discharge riveting devices comprise an upper die 1 and a lower die 2, wherein the upper die 1 is provided with an upper die punch 11, the lower die 2 is provided with a lower die punch 21 and a stripper plate 22, the lower die punch 21 is provided with a U-shaped groove for placing a rivet 4, the lower die punch 21 is internally provided with an inductor 5, the lower die punch 21 is internally provided with a through hole for inserting the inductor 5, the inductor 5 is fixed through a tightening screw 7, the tightening screw 7 is screwed into a locking inductor 5 from the side wall of the through hole in the lower die punch 21, inductors 5 are arranged in the lower die punch below each to-be-riveted screw, and each inductor 5 is connected with an induction indicator lamp.

The stripper plate 22 is provided with an air blowing channel communicated with the U-shaped grooves for mounting rivets, an air blowing port 6 at the end of the air blowing channel is aligned with the U-shaped groove, the other end of the air blowing channel is connected with an air path system of the die, each U-shaped groove on the stripper plate 22 is communicated with air blowing channels, and the air blowing channels are connected to the existing air path system of the die in parallel or in series.

And (3) placing the workpiece to be riveted on the stripper plate 23, sensing whether the rivet is placed in the U-shaped groove in place by the sensor 5, if so, carrying out punching riveting, otherwise, indicating the position of the U-shaped groove without the rivet, and blowing away the waste pin in the U-shaped groove through the air blowing port 6 during a punching return stroke.
