Riveting machine (also known as riveting machine, riveting machine, riveting machine, riveting machine, etc.) is based on the principle of cold rolling developed a new type of riveting equipment, refers to the rivet can be riveted together with mechanical equipment. The device is compact, stable performance, easy and safe operation. Riveting machine mainly by rotating and pressure to complete the assembly, mainly used in rivets (hollow rivets, hollow rivets, solid rivets, etc.) riveting occasions, common pneumatic, hydraulic and electric, single and double head and other specifications. The common types are automatic riveting machine (mainly for semi-hollow riveting machine riveting, automatic cutting, riveting efficiency!) And spin riveting machine (riveting machine is divided into pneumatic riveting machine and hydraulic riveting machine, Mainly used for solid rivets, rivets or larger hollow rivets).
Riveting machine is corns and other riveting equipment collectively! Usually people are referring to Riveting Machine, Riveting Machine by power mode can be divided into: pneumatic Riveting Machine and Hydraulic Riveting Machine;
Mainly used in, rivets and other aspects of hollow rivets; riveting riveting machine points: radial riveting and swing riveting;
1, high-speed insertion speed
2, component positioning sensor
3, automatic recovery performance programming
4, AC servo motor positioning system
5, built-in PC system
Riveting machine cold rolling riveting method is the use of riveting the local pressure rivets, and around the center of the continuous swing until the riveting riveting method. According to this riveting method cold grinding trajectory, it can be divided into pendulum riveting method and radial riveting method.
Punch Riveting method is the rivet head of the workpiece first point contact by the cylinder or hydraulic cylinder pressure on the workpiece surface at the same time all-round rolling, the workpiece surface instantaneous deformation riveting effect. Radial riveting rule is to press the center of the metal deformation and then the surrounding deformation rolling.
In terms of the two riveting methods, radial riveting on the workpiece surface deformation pressure than swinging riveting larger, while its positive and negative spherical pressure as a direct, so vulnerable, high failure rate, after many years we Practice, this method has been gradually replaced by rolling type, and its quality of the appearance of the workpiece is not as good as the rolling type, and its failure rate is high, so the customers have chosen swing type rotary riveting machine.
When riveting the workpiece, the stability of the swinging type is good, the workpiece does not appear radial jitter, which affects the processing quality, especially in the arc-shaped riveting, the use of swing-riveting, the workpiece is basically Do not touch the workpiece without hand, we can complete the riveting work.
Screw riveting standard chucks are: 3 ° and 5 °, special specifications can be customized!
Riveting machine works generally divided into two types, namely, radial and swing roller type, they are in the structure and movement on the trajectory have a greater distinction is now simple and brief introduction is as follows:
Radial riveting machine:
The motor transmits the motion to the main shaft through the coupling, and the main shaft transmits the motion to the spherical kinematic pair through the small tooth difference planetary mechanism. At the same time, the hydraulic system drives the piston and the spherical pair to press downwards. When the rivet head touches the rivet, Rivets centerline (ie, the spindle centerline) according to 11 Plum movement rivets non-slip rolling track to complete the riveting work.
Rolling riveting machine:
The motor transmits the motion shaft through the coupling, meanwhile, the hydraulic system drives the piston to press downward along with the main shaft. When the rivet head touches the rivet, the riveting head revolves around the center line of the rivet (ie the center line of the main shaft) Under the action of force rotation, thus forming a non-slip rolling.
The main features
Riveting machine for its convenient, efficient and easy to operate features more and more accepted by the majority of manufacturers customers.
Riveting machine according to the type of structure can be divided into a wide range of types, there are slide rail, but also turntable, but the principle is similar, are set by the workpiece to the riveting area displacement, and then completed by the riveting riveting process.
The displacement of any work piece can be regarded as the result of moving in three directions. The X and Y axes are left and right and front and back and the Z axis is up and down. Thus, a basic numerical control structure is determined. CNC riveting machines generally have a zero point, also known as the reference point, based on this point, we need to point all the need to riveting number and coordinates of the calibration, this process is necessary, and then these coordinates and height needs to be entered Equipment data entry page, so that the machine knows how to rivet those points, these points were in what place, how much height.
After the coordinates of these points are input, the program of CNC riveting machine can work. The servo of the machine will drive the workpiece to reach the first point we input under the control of the program. In this position, the riveting workpiece should be just at the rivet head Under the axis, the device also needs to calculate the Z value of the coordinate, that is, the height value, and determine the feed amount of riveting. After all preparations are ready, the equipment can start riveting.
