Road Sign SPR Machine,Road Sign Self Piercing Riveting Machine
Traditionally, the riveting technology of traffic Road Sign is drilling, riveting and grinding, which requires punching and riveting, which is time-consuming. Here is a quick and firm riveting new technology for traffic signs.
The new technology adopts self piercing riveting technology. Its principles are as follows:
Technical Principle and Procedure: The blank holder first moves downward to pre-press the riveting material to prevent the material from flowing into the die under the rivet force, and then the punch moves downward to push the rivet down to pierce the upper material. Under the joint action of die and punch, the rivet tail opens in the lower metal to form a bell shape for locking and connecting. When riveting two layers of the same metal material, the thicker layer is placed in the lower layer; when riveting two layers of different metal materials, the plastic material is placed in the lower layer; when riveting metal and non-metal materials, the metal material is placed in the lower layer.
The advantages of the process are as follows: 1. High connection strength.
2. No drilling, direct riveting.
3, rivets do not need manual assembly.
4, efficiency is very high.
Design parameters 1, Number of heads: 2 heads 2,Use rivet diameter: 5.3mm/3.3mm 3, Pressure of gas-liquid booster cylinder:150KN (15T) 4, Total stroke:100mm 5, Boost stroke: 10mm 6, Distance between upper and lower dies: 60mm 7, C-type plate opening size: 200mm 8, Throat depth of type C plate: 800mm 9,Center distance between two riveters: 40-120 mm 10, Overall size:1500mmX1200mmX1450mm 11,Net weight: 1200KG
