How is the production and processing accuracy of rivet machine?

In addition to the requirements of the matrix with high enough strength and toughness in the work of the riveting machine, its surface performance is very important to the working performance and service life of the die. These surface properties refer to: wear resistance, corrosion resistance, friction coefficient, fatigue performance, etc. Now let's talk about the machining accuracy of the riveting machine.

1, rivet machine production process is a continuous local deformation process, its deformation is much smaller than stamping, rolling, and each deformation is only in the E region between the lattice relative slip, rarely formed shear and dislocation. Therefore, the pressure required for deformation is only 7%-10% of the stamping and 10-15% of the rolling, which basically eliminates the phenomenon of bulging belly, thick pier and cracks under strong pressure.

2. After riveting, the metal deformation direction is consistent, and the continuous fiber flow perpendicular to the load direction is formed, and the metal structure is not damaged, thus greatly improving the bearing capacity of the riveting surface. It is confirmed by Larter experiment that all the parameters exceed the target by more than 30%. Torque and air tightness results also fully meet the requirements of excellent quality.

3. Due to the extrusion of the riveting head and the uniform deformation of the metal, the appearance of the riveting part is of high quality and abnormal brightness.

4, the riveting adjustment work is replaced by fine-tuning nut, riveting head adopts split structure. In one working cycle, prepressing and riveting can be completed at one time without fixture or clamping. Not only does it save people, it saves time, and it doesn't require experience. It is estimated that the processing cost is more than half of the traditional method.

5. Wide range of application. As long as the replacement value of only dozens of yuan riveting head can meet the requirements of riveting different specifications, different types of ball pins. Especially large size, long size ball pin processing is more convenient.

6. Low noise, safe and reliable. After the field test, the noise is less than 75dB, much lower than stamping, slightly lower than rolling. In a word, using riveting technology processing ball pin sealing has incomparable advantages, it is good quality, good appearance, time saving, high efficiency. It can be predicted that riveting will be widely used to replace the traditional sealing process in the near future.

Do you know the causes of rivet machine damage?

Rivet machine in the process of use will encounter damage phenomenon, then, we will give you analysis of the cause of the damage of the rivet machine:

1, belt return section adhesion slag. Cleaner blade wear, not close to the belt surface, ash and slag viscosity increase, high water content will constitute the belt surface with slag. The belt of the return section of the pipe belt machine has a vertical downward organization, and the ash root of the belt return section adhesion can fall into the dehydration bin here, which is obviously different from the scheme organization of the pipe belt machine of our factory.

2, ash slag moisture content is high. The filter element and drain pipe of buffer slag bin are blocked, the drain pipe of gate plate is blocked, and the filter element is not washed back in time after slag discharge, which will lead to too much water in ash slag belt.

3, belt running deviation roller packing wear, roller group roller operation is not normal influence belt running deviation, the roller at the high point of belt offset has a large force, long hours of operation roller simple wear and thin until cracking. Now the roller wear more out of the belt section before unloading.

4, riveting machine bearing quality. Some idler working surface cleaning, due to bearing quality doubt will also constitute a transition insensitive or card astringency, and then appear wear.

5, buffer slag bin ash straight row. The slag out of the slag dredger without a constant dehydration, directly transported to the dehydration bin by the tube belt machine, will constitute more water content of the slag, the increase of the tube belt machine no-load hours, accelerate the wear of the roller.

6, the sealing function of the rivet machine is poor. Water slag accumulation into the roller bearing, forming a smooth or poor transition sensitivity and wear.

7, thin pulp type of ash wear roller. Sometimes the slurry slag from the dredge machine is simply adhered to the tape and falls onto the bracket and roller shaft at both ends of the roller. On the one hand, it will wear the roller body, on the other hand, it will agglomerate and form a card.

8. Wear and tear of the roller body by ash and slag with larger granularity. Sometimes the slag machine out of the larger particles of ash, adhere to the tape, hard and sharp material on the roller body wear quickly.

The rivet machine is more and more convenient, efficient and easy to operate for the majority of manufacturers accepted by customers. Rivet machine can be divided into many kinds according to the structure type, there are sliding rail type, there are also rotary disc type, but its principle is similar, are set, so that the workpiece displacement to the riveting area, and then the riveting machine to complete the riveting process.

The biggest characteristic of automatic rivet machine: it is an integral machine design, the body with a thick lower arm, such a design can make the desktop more stable, safer operation, there will not be a phenomenon of nail. Pneumatic riveting machine is designed for riveting four - claw nails of furniture. It also has a different place, is the leaky nail device and duck tip structure, so that the four-claw nail leakage is no longer difficult, improve product quality and work efficiency. Rivet machine can be divided into many kinds according to the structure type, there are sliding rail type, there are also rotary disc type, but its principle is similar, are set, so that the workpiece displacement to the riveting area, and then the riveting machine to complete the riveting process.

We can regard the displacement of any workpiece as the result of three directions of movement, X,Y axis is control left and right and front, Z axis is control up and down, thus, a basic NUMERICAL control structure is determined. Nc riveting machine is generally a zero, can also be referred to as the reference point, use this as a benchmark, we need to put all need riveting points are numbered and coordinates calibration, this process is necessary, and then need to enter the coordinates and height data entry page to the device, thus let the machine knows how to riveting those points, these points respectively, where, how much height.

After these points coordinates input, nc riveting machine program can operate, the servo mechanism of the machine will be under the control of the program, drive the workpiece reach we entered the first point, in this position, riveting artifacts should be just under the axis of the rivet head, the equipment and the coordinates of the Z value, which is highly value calculation, determine the feeding of riveting, Everything is ready for riveting.
