Description

Technical Field

[0001] The utility model relates to the technical field of production and processing equipment, in particular to a full-automatic multi-position drilling and nailing machine. Background Art

[0002] At present, the processing and production of nail installation holes are mainly based on manual work, assisted by manual installation and simple clamping to complete the work of punching and pressing nails. That is, the operator operates the punch press and pneumatic punch press, the worker places the nail on the installation hole, and then the pneumatic press presses the nail into the installation hole. Since the workers are always operating in front of the machine, the labor intensity of the workers is high. And the nails have to be placed on the installation holes by hand, so there is a certain risk. In addition, the workers are often replaced, and it is difficult to meet the quality requirements, so the quality yield cannot be guaranteed.

[0003] Manual labor mainly has the following three disadvantages:

[0004] 1. The nail installation hole will bulge in the opposite direction. Because the punching process is used, the cut hole is a blind hole. When punching, the excess material in the hole will spread to other directions. The bottom of the hole is thin, and the excess material will squeeze the bottom of the hole and bulge outward.

[0005] 2. The nails are placed in the installation holes by workers manually to the pressing position, which is very dangerous when the workers are tired or negligent.

[0006] 3. Quality is difficult to guarantee. Due to manual operation, quality is manually controlled. Workers are often rotated, and new workers do not fully understand the quality requirements, which will cause certain quality deviations. Utility Model Content
