Technical Solution For Fully Automatic Iron Frame Welding Production Line
Our company designed and manufactured a fully automatic iron frame welding production line for Guangdong Xinhua Electric Co., Ltd. which is equipped with automatic unloading and automatic stacking. The original single worker at a single station manually spot welding produced about 1,000 pieces a day (12 hours). After installing 8 stations on the production line and 3 workers maintaining it, the production capacity can be about 7,500 a day (12 hours), which greatly improves the production capacity.
Technical solution for fully automatic eight-station iron frame welding production line
I. Design thinking
1. Machine structure: 1. The welding host is an open platform. 2. The rotation adopts a 90° splitter (composed of an electromagnetic clutch, a reduction box, and a motor). 3. The automatic welding gun is composed of a servo, a ball screw, and a spot welding mechanism. 4. The welding mold is composed of a 90° beryllium copper positioning. 5. The strip automatic clamping (feeding in and out) and unloading device are composed. 6. The strip conveying adopts a synchronous belt, a reduction box, a servo drive, and the material lifting is composed of a cylinder (1 strip at a time). 7. The material grabbing mechanism is composed of a finger cylinder, a slide cylinder, a servo drive, (1 strip is delivered each time) and is connected to the lower platform of the punch press by a material divider (two sets of servos). 8. The automatic line consists of four eight-station welding hosts as shown in the figure.
2. Unloading device: It is composed of a four-square frame with X, Y, Z three-axis linkage mechanism, equipped with finger cylinders, clamping cylinders, rotating cylinders, etc. The unloading space is 1400×1400×1950. The stacking quantity is 125 layers×4=500, and the eight-station unloading adopts a four-station single-side form (that is, each welding host has two stations sharing one unloading rack).
3. Synchronous belt conveyor: It is composed of material distribution, material guiding, orientation, conveying, and escort devices, as shown in the figure.
4. Brief description of single-station action: Material lifting platform (1 strip) When the machine recognizes that there is material, the material lifting cylinder moves and lifts the strip for the first time. The finger cylinder moves to grab the material and send it to the welding rotating station by the servo and then returns to its original position. The divider rotates 90°. The second material grabbing cylinder moves to send the strip to the welding rotating station and then returns to its original position. The clamping and positioning cylinders move, and the servo quickly moves forward to the welding position for the first spot welding (4 points). After the welding is completed, the servo returns to its original position, the clamping and positioning cylinders release, and the divider rotates 90°. The third material grabbing cylinder moves to push the strip into the welding rotating station. The positioning and clamping cylinders move, and the servo quickly moves forward to the welding station. After the second spot welding (4 points), the servo returns to its original position, the clamping and positioning cylinders release, and the divider rotates 90°. The fourth material grabbing cylinder moves to push the strip into the welding rotating station and returns to its original position. The servo quickly moves forward to the welding station for the third spot welding (4 points). Point) clamping, positioning cylinder release, after spot welding, servo returns to its original position, divider rotates 90 °, servo quickly moves forward to the welding station for the fourth spot welding (4 points), after the end, the unloading mechanism links to take the material and places it on the pile floor drag plate according to the rules... the action is analogous.
5. Synchronous belt conveying action process: the edge strips are orderly conveyed to the 1#, 2#, 3#, 4#, 5#, 6#, 7#, 8# stations (synchronized with the divider) through the positioning synchronous belt. When each station determines that there is an edge strip, it grabs the material in order, 1# grabs the material first, 2# follows, 3# follows, 4# follows, 5#, 6#, 7#, 8# continues, forming an automatic cycle.
6. Production efficiency: single station 4 pieces/minute.
