An automatic production line for spiral ground piles

Abstract

The invention discloses an automatic production line of a spiral ground pile. The automatic production line comprises sharp conical part automatic forming equipment, wherein the sharp conical part automatic forming equipment comprises multiple taper pile machines which are arranged in parallel; each taper pile machine comprises an engine base, a shell and a spindle; a die and a hammerhead are mounted in the die cavity of the spindle; a rolling shaft group is arranged between the hammerhead and the shell; the hammerhead comprises a plurality of hammerhead blocks; the die is formed by splicing at least three die blocks; the splicing part of each die block is triangular; a partial conical-surface groove is arranged at one side of the top of the splicing part; a gap is reserved between the two side walls of the splicing part of the two adjacent die blocks; the gap is closed at the splicing center of the die blocks; the partial conical-surface groove of the die blocks are spliced to be an entire conical hole; and the die blocks are respectively and correspondingly arranged on the hammerhead blocks one by one. With the adoption of the technical scheme, the difficult problem that a steel pipe with a large pipe diameter in the prior art cannot reach a solid conical point in a cone forming process can be solved.

Description

technical field [0001] The invention belongs to the field of processing equipment for spiral ground piles, in particular to an automatic production line for spiral ground piles. Background technique [0002] In the Chinese patent application with the application number 2012100065083, the inventor proposed: an automatic production line for spiral ground piles, including pipe cutting equipment, automatic punching equipment, automatic nut welding equipment, pointed Cone automatic forming equipment, automatic drilling equipment and automatic piercing welding equipment, the conveying device, pipe cutting equipment, automatic punching equipment, nut automatic welding equipment, pointed cone automatic forming equipment, automatic drilling equipment and automatic piercing The sheet welding equipment is uniformly controlled by the control device. The use of automated equipment to process and manufacture spiral ground piles has a high degree of automation, low labor intensity, less l...

AI Technical Summary

Problems solved by technology

However, the mold is composed of upper and lower mold blocks, because the two mold blocks are in surface contact, and some conical grooves are formed on the joint surface. The existing technology cannot guarantee the full fit of the joint surface, so the two Part of the conical groove on the die block cannot be closed into a complete conical tip, and the force cannot be applied to the tube tip, so that the steel pipe can only be processed into a conical tube, and a solid conical tip cannot be formed at the end of the tube
