The basic principle of the tunnel small pipe drilling machine ahead of the small pipe grouting is to drive (drill, press) the small pipe into the ground at a certain extrapolation angle along the periphery of the tunnel excavation face, and pass the pressure of the grouting pump to pass the slurry. Small conduits infiltrate and diffuse into the pores or fractures of the rock to improve the physical and mechanical properties of the rock mass. This article will introduce you to the safety specifications of automatic punching machines. The document punching machine needs to meet the following requirements: when the punching machine has a specified thickness of 30mm, it still maintains a good punching quality; the punching tool is resistant to wear and has a long working life; the service life is long and the warranty period is low. Rework rate; high work efficiency and stable performance. The base of the punching machine is provided as a support arm on the base of the base; the electromagnetic attraction mechanism realizes linear movement up and down, and is disposed on the support arm; the bracket is used for limiting nonlinear movement of the electromagnetic attraction mechanism, and is disposed on the electromagnetic attraction mechanism It is used to limit the nonlinear movement of the electromagnetic attraction mechanism; the cutter mechanism is fixed to the electromagnetic attraction mechanism, and the document is punched up and down with the electromagnetic attraction mechanism. When the user presses the start button to start the document punch, the control circuit board is powered, and the control circuit board energizes the electromagnetic coil to generate a magnetic attraction to move the armature down the optical axis. The powerful software development capability provides a strong guarantee for system stability, and the machine software is free to upgrade for life, so that the machine will remain in the leading position for a long time. Scope of application: mainly used in soft circuit boards, film, membrane switch, electronics, printing, packaging, nameplate and other industries.
