Needle tube automatic needle moving machine

Abstract

The invention discloses an automatic needle bending machine for a tube welded with columnar needles, and aims to bend the columnar needles on the tube. The automatic needle bending machine comprises a rack, wherein a supporting mechanism is mounted on the rack; a needle bending link rod mechanism is mounted on a vertical side surface of the supporting mechanism, and comprises a need positioning plate for fixing the columnar needles in the peripherally radial direction of the rube; link rods are arranged above the need positioning plate; needle bending shafts are arranged at the end parts near the columnar needles of the link rods; the upper ends of the link rods are fixed with a bracket through bearings; claw forceps are mounted below the need positioning plate; the outer ends of the claw forceps are connected with a first power device; the first power device can drive the claw forceps to clamp the columnar needles; a second power device is arranged above the needle bending shafts, is connected with the needle bending shafts, and can drive the needle bending shafts to bend the columnar needles downwards. The automatic needle bending machine is a special device for bending the columnar needles, can completely replace manual operation, has a high degree of automation, and then improve the production efficiency, save labor resources and reduce the cost; besides, the automatic needle bending machine has the advantages of being convenient to operate, precise to control, stable in needle bending and high in finished product ratio.

Description

technical field [0001] The invention relates to a bending tool, in particular to an automatic needle-moving machine for needle-shaped tubes used for bending cylindrical needles of needle-shaped tubes. Background technique [0002] The needle-shaped tube heat exchange tube group made of needle-shaped tubes has high heat transfer efficiency, and is especially suitable for compact waste heat boilers, fuel oil, gas-fired boilers and oil heaters. Welded on the surface of the heat exchange tube, viewed from the same cross-section of the needle tube, multiple cylindrical needles are equally arranged on the outer circumference of the needle tube; Arranged in multiple rows, wherein the length, diameter, spacing and inclination of the columnar needles can be flexibly set as required. It has the advantages of good heat transfer performance, small size, light weight, good self-cleaning and wear resistance, especially for the heat exchange of oil medium, which has irreplaceable advantag...

AI Technical Summary

Problems solved by technology

The defects of this invention include: first, the bending angle of the guide pins cannot be well controlled, that is, bending at any angle cannot be realized; The bending cannot be applied to the bending of multiple rows of guide pins on the same surface; the third is that there is no fixing and protective device for the starting part of the guide pin bending and the bending process, which may easily cause the guide pins to break or fall off. Therefore, The yield rate is poor; Fourth, for the bending of columnar needles arranged in equal parts on the circumference of the needle tube, the positioning and fixing of the needle tube and columnar needles cannot be realized, nor can it be applied to the bending of the columnar needles
