Description

Balanced pressure type waterstop vulcanizing machine

Technical Field

The utility model relates to a heating vulcanization equipment technical field, in particular to balanced pressure formula waterstop vulcanizer.

Background

Because the length of the construction working face is long or short, the length of the water stop belt is difficult to be consistent with that of the construction working face. When the length of the construction working face is smaller than that of the water stop, the redundant part of the water stop needs to be sawed. When the length of the construction working face is larger than that of the water stop belts, the end parts of the two water stop belts are required to be lapped together for welding, and then a water stop belt welding machine is used.

Among the prior art, the waterstop welding machine includes hot plate and last hot plate down, and the one end of hot plate and the one end of last hot plate are passed through rigidity hinge joint down, and the other end of hot plate and the other end of last hot plate are through rigidity pressurization locking hand wheel pressurization fixed connection down, and lower hot plate and last hot plate are provided with circulating water cooling channel, and circulating water cooling channel is provided with water inlet and delivery port, and circulating water cooling channel's water inlet and water source intercommunication. The water source refers to a mobile cooling water tank.

The prior art waterstop welding machine has the following disadvantages.

1. Because the one end of lower hot plate and the one end of last hot plate are articulated through the rigidity hinge, so, after the waterstop softened of heating, the waterstop receives the extrusion force effect of waterstop welding machine lower hot plate and last hot plate, extrudes to all around, and the pressure decline of waterstop welding machine lower hot plate and last hot plate to the waterstop this moment, in order to keep sufficient pressure to the waterstop, just must screw up the hand wheel once more in time and carry out the pressure compensation and dash, and the other end is articulated for the rigidity hinge, can't carry out both ends and lock simultaneously, all can cause because of the different welding fastness of both ends pressure descends like this.

2. Because the lower heating plate and the upper heating plate are provided with the circulating water cooling channel which is provided with a water inlet and a water outlet, and the water inlet of the circulating water cooling channel is communicated with a water source, return water needs to be discharged through the water-cooled cooling water stop, so that the environment is polluted, and in addition, new water needs to be continuously injected, and the water resource is greatly consumed. Because the construction welding of building sites such as tunnels often removes, does not have sufficient water source, so can only be with return water reuse, because the lower hot plate of high temperature and last hot plate heat water, so, the temperature of return water is very high, lets the interior circulating water temperature of water tank rise very easily, and the continuous cooling operation effect is extremely poor. If continuous welding is needed, water is continuously changed, which not only has high labor intensity, but also pollutes the environment and consumes water resources.

3. Because the lower heating plate and the upper heating plate in the prior art need to bear large clamping force, the heating aluminum body is thick, the heating aluminum body becomes slow when being heated because of the thick heating aluminum body, and after welding is finished, the residual temperature is high, and the cooling is slow.

Thereby reducing the service performance of the water stop vulcanizing machine.
