A punching device for advanced small catheter punching equipment

Abstract

The invention provides a stamping device of advanced small pipe punching equipment. The stamping device comprises a base, wherein a die holder is arranged on the base, and guide seats which can sliderelatively are correspondingly installed on the die holder; clamping dies which can slide relatively are correspondingly arranged between the two guide seats; and actuating mechanisms which are used for driving the clamping dies to move are respectively arranged on the left and right sides of the die holder, and guide mechanisms are respectively arranged on the front and back ends of the die holder. When the stamping device provided by the invention is used for operating, the first-stage positioning guide is formed on a guide pipe by the two clamping dies, the second-stage positioning guide isformed again in a horizontal direction by a side limiting piece, the positioning guide is formed in a vertical direction by the guide mechanisms on the both sides, and a stable part and a connectingarm are used for fixing and positioning, so that the processing precision of the stamping device is guaranteed to the maximum, the gap between the two clamping dies can be guaranteed by the connectingarm, the maximum return distance of the guide seats can be guaranteed by the stable part, the overall stability is good, and the reliability is high.

Description

technical field [0001] The invention belongs to the technical field of advanced small catheter processing equipment, and in particular relates to a punching device of advanced small catheter punching equipment. Background technique [0002] The advanced small conduit is used in the excavation construction of tunnel engineering, and is mainly used for the pre-support of the weak broken zone, shallow buried section, tunnel entrance bias section, sand layer section, sand pebble section, fault broken zone and other sections during the self-stabilization period. The condition and stability of the surrounding rock can be changed through the advance small conduit grouting, and the grout can be in close contact with and solidified after being injected into the weak and loose strata or cracks in the water-containing broken surrounding rock. The grout replaces the water and air in the soil particles and rock fissures by filling, splitting, etc., and occupies its position. After a cert...

Problems solved by technology

In the traditional advanced small catheter processing and manufacturing, the cone head making and drilling processes need to be carried out manually. The process flow is many, the labor intensity is high, the processing speed is slow, and the labor cost is high.

Ordinary drilling equipment has poor adaptability and cannot accurately drill holes on the small lead tubes. It is difficult to meet the requirements of use. It is urgent to design a processing equipment that can accurately drill holes.
