Light pole bending device

Abstract

The invention relates to the field of street lamp production, and in particular relates to a lamp pole pipe bending device. The device comprises a rotating platform and a positioning platform, wherein a rotating plate is rotatably connected to the lower end surface of the positioning platform; a free end of the rotating plate is fixedly connected to the rotating platform; a cylinder is fixedly mounted on the rotating platform; two connecting plates which are symmetrically arranged relative to a piston rod of the cylinder are hinged with the piston rod of the cylinder; circular holes are formed in the connecting plates; supporting columns of which the bottom ends are fixed to the rotating platform are sleeved with the circular holes; arc surface plates are fixedly connected to the free ends of the connecting plates; an arc-shaped groove is formed in the positioning platform; electromagnets are arranged at two sides of the groove; an arc surface pressing plate is arranged above the electromagnets; a spring is fixedly arranged between the arc surface pressing plate and the electromagnets. According to the scheme, the lamp pole pipe bending device has the advantages that the arc surface plates extend into a lamp pole and are outwards propped to the inner wall of the lamp pole, so that the lamp pole can be prevented from being pressed and flattened during being bent, and as a result, cables can be paved during mounting.

Description

technical field [0001] The invention relates to the field of street lamp production, in particular to a lamp pole bending device. Background technique [0002] Street lamp refers to a lamp that provides lighting for the road. It is a whole composed of lamps, electrical appliances, light sources, lamp poles, lamp arms, etc. Street lights are generally divided into high-pole street lights, middle-pole street lights, road lights, garden lights, lawn lights, etc., but no matter what type of street lights, in order to facilitate the laying of cables and long-term use, metal tubes are generally used as lights. pole. At present, the light poles of many street lamps are bent to a certain extent in order to make the lighting effect of the lamps better, or for the sake of appearance. The light pole is generally bent by a pipe bender. The commonly used pipe bender generally fixes one end of the light pole through a clamp, and then applies force to the unfixed part of the light pole t...

Problems solved by technology

However, bending the light pole by such a bending method will easily cause the part connected to the bending section to be crushed, making it difficult to pass through the bending section when passing the cable from the inside, or directly blocking the situation.
