Two shortcomings, first: owing to needing bigger power when bending pipe arm starts, and existing be short of power so that it is at good bar
Rise curved under part, and the space in pipe bender head is extremely limited, it is impossible to strengthen power-equipment, the bending machine of the most this structure
Can only be confined to bend the tubing that diameter is less；Second, sprocket wheel is installed with spindle drive by key, and sprocket wheel leaves a keyway again,
Then chain is installed with chain gear transmission by key.This structure its mainly transmitted by two keyways and key, keyway and
Key easily weares and teares and makes power transmission unreliable.
Therefore, based on these problems, it is provided that one can strengthen driving force, avoid keyway and the easy wear problem of key simultaneously
Main shaft of pipe bender have important practical significance.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that one can strengthen driving force, keeps away simultaneously

This utility model solves it and technical problem is that and take techniques below scheme to realize:
A kind of main shaft of pipe bender, including main shaft and head sprocket, described main shaft is divided into three sections of axles, including first paragraph axle, the
Two-stage nitration axle and the 3rd section of axle, the middle part of described head sprocket is provided with gear, and described gear has three layers, and respectively first
Layer tooth, second layer tooth and third layer tooth, described main shaft of pipe bender also includes: the quantity of described head sprocket is two, is first
Head sprocket and the second head sprocket, described second segment axle is provided with bending pipe arm, with bearing on the end face of described head sprocket one end
Connecting, the end face of the described head sprocket other end is provided with a gear grooved, and described main shaft two ends are provided with and described gear grooved phase
The connection gear coordinated.
In above-mentioned main shaft of pipe bender, further, a described bearing is fixed with bending machine and is connected, another bearing
It is connected with last item portion.
In above-mentioned main shaft of pipe bender, further, described last item portion includes end cap and standing screw, described fixing spiral shell
Bar is fixing with end cap to be connected, and described standing screw is fixing with described bending machine to be connected.
In above-mentioned main shaft of pipe bender, further, described first head sprocket and the second head sprocket are electric with first respectively
Machine and the second motor are connected by tooth bar.
Advantage of the present utility model and good effect be:
1, this utility model is by being provided with two head sprockets, can strengthen driving force.
2, this utility model is connected by gear and gear grooved, thus avoids keyway and the easy wear problem of key.
