Abstract
A pipe bender comprises a clamping fixture and a heater, wherein the clamping fixture adopts a grooved wheel structure; two circles of slideways are respectively formed on the front side and the rear side of the clamping fixture in positions near edges; a semi-circular heating pad is mounted between the two slideways; and the heater is laid in a groove body on one edge of the clamping fixture, and comprises heating resistance wires. The pipe bender has the advantages that the design is reasonable; and the use is convenient and practical.
Description
Technical fieldThe present invention relates to a kind of tubing processing unit (plant), especially a kind of bending pipes processing unit (plant).
Background technologyKnown, in productive life, often need various tubing, need some bend pipe tubing sometimes especially.At present, the general cost of bend pipe processing unit (plant) is higher, and needs the workman to operate processing, is not suitable for promoting the use of.
Summary of the inventionThe purpose of this invention is to provide a kind of simple in structure, easy and simple to handle, safe and reliable bending machine.
The present invention includes mold and heater, said mold is the sheave structure, presses close to edge at the positive and negative of mold and all offers a circle slideway, and a semicircular arc heating cushion is installed between two slideways; In the edge of mold cell body, lay heater, said heater is made up of resistive heater.
During use, the user will treat that crooked tubing inserts in the cell body of mold, and entangle tubing with the semicircular arc heating cushion, and heating cushion is in the bending point place of tubing, then with heating cushion and heater energized all.Heat up through heating cushion and heater tubing heated, make tubing softening gradually, but this moment the user just the both hands branch hold the tubing that is in the heating cushion both sides, inwardly firmly break tubing then off with the fingers and thumb and carry out bending, flexibility can be operated according to actual needs.After the heating, open a side junction of heating cushion, just can from mold, take out tubing.
Compared with present technology, beneficial effect of the present invention is: reasonable in design, convenient and practical, but quick manual carries out bending operation to tubing.
Description of drawingsFig. 1 is a stereochemical structure sketch of the present invention.
Drawing reference numeral: 1 is that mold, 2 is that heater, 3 is that slideway, 4 is heating cushion.
The specific embodimentIn stereochemical structure sketch of the present invention shown in Figure 1, comprise mold 1 and heater 2, said mold is the sheave structure, presses close to edge at the positive and negative of mold and all offers a circle slideway 3, and a semicircular arc heating cushion 4 is installed between two slideways; In the edge of mold cell body, lay heater, said heater is made up of resistive heater.
