Mould dismounting machine of screw rod drilling tool

Abstract

A screw drill mold-stripping machine comprising a main bed body (1), a fixing clamp (3) fixed thereon, a movable clamp (4) movably connected onto the main bed body, a pullout bed body (2) fixedly connected to the main bed body, a puller (5) arranged on the pullout bed body, a support frame (6) supporting the puller and a petroleum pipe workpiece, and supporting trolleys (7) supporting a workpiece holding a pipe. A chain drive mechanism is arranged on the puller and on the movable clamp. An adjusting mechanism is arranged on a running wheel set of the puller. The mold-stripping machine saves manpower, increases operational efficiency, and, during a pullout process, adjusts the puller to a stable state.

Description

technical field [0001] The invention relates to a demoulding machine, in particular to a demoulding machine for screw drilling tools used in the assembly and disassembly of screw stators and mandrels for various oil exploration and geological exploration. Background technique [0002] In the process of oil exploitation, after the make-up and break-out torque of the threaded pipe string workpiece used for petroleum and geological use is greater than a certain value, manual disassembly and assembly work cannot be performed. Therefore, a kind of equipment is urgently needed to complete this work. At present, threaded pipe The most important tool for the disassembly and assembly of column workpieces is the screw drilling tool disassembler. [0003] The function and performance index of the disassembly machine will directly affect the quality and operation efficiency of the assembly and disassembly of drilling tools. At present, there are two types of disassemblers, namely 1. Si...

Problems solved by technology

For example, the single-arm punching machine only uses a single piece of maintenance. Due to the lack of functions, it is difficult to ensure the assembly quality of the drilling tool, and the operation efficiency is very low, and it is facing the situation of being eliminated; The assembly quality of drilling tools is high and the work efficiency is high. However, due to the low output torque of the equipment, the scope of application is narrow, especially the high cost and high maintenance cost, which limits the popularization and application of this type of equipment; the disassembly and assembly of the above two types There is also a common shortcoming of the machine: during disassembly and assembly, due to the large torque for making up and breaking out of the pipe string workpiece, sometimes its thrust and pull cannot meet the requirements of the operation.
