| The introduction and working principle of elbow machine
Bend machine is mainly used for carbon steel and alloy steel price of bend forming, if you need the product is stainless steel elbow, please select cold push bend machine equipment mainly include: frame, main oil cylinder plate (including the main oil cylinder), active pushing plate, the plate before, semi-automatic feeding mechanism, intermediate frequency adjust coil frame (including intermediate frequency heating coil), intermediate frequency power supply, electric control system, etc.
The raw material of steel pipe is seamless steel pipe, welded steel pipe and rolled steel pipe.
The equipment can produce elbow product specifications range: outside diameter: Φ21mm ~ Φ1620mm;Wall thickness: 5mm ~ 120mm Angle: we can be adjusted and customized according to customer requirements
Put the cut raw materials on the core rod of the elbow mold, put the intermediate frequency induction wire trap on the end of the elbow mold core, start the cooling water pump and the intermediate frequency power supply, heat the raw materials to about 800°C, and then start the pushing machine to push the elbow.
Select the main push pump according to the elbow, select the speed of feeding, the gate, the mandil rod heated to the working temperature began to push, the work speed is adjustable, push to the middle point of the machine automatically stop, the hydraulic gate gate dead, the core rod feeding, loosen the gate back to the end, the gate gate to the outside diameter of the rod began to push.Note: the main push pump can be used at the same time, generally only one can be used.It can also be used to step back without stopping.Reverse pump can not be used at the same time, only one can start, the other standby.Feeding pump can only be used when feeding.The safety pressure of the main oil pump hydraulic system is set as that of the auxiliary cylinder hydraulic system.There are travel switches at both ends of the push machine travel, the actual travel should be less than the maximum travel, that is, the two ends of the push plate before and after the actual end are left with some margin, so as to avoid the cylinder piston running to.
The structure and working principle of the push machine
Pushing machine equipment for double cylinder or four cylinder average speed forward, pump station valve platform adopts integrated form.The pumping station is composed of multiple stages. There are 2-3 working pumps for the equipment of the first to the sixth specifications, and 1 working pump station for the bending test equipment of the seventh and eighth specifications. One book and one historical background is set.
Pushing machine is divided into one push push bending in two and three push push two forms, hydraulic two push bending machine, the total stroke of standard type can be customized according to the requirements of users directly.
Pushing machine material by the feeding machine, driving steel wire rope, push pipe, steel wire rope wheel, to work, the original pipe to be expanded into the equipment.
The intermediate frequency power supply is installed in the front of the equipment, and the intermediate frequency induction coil is secured on the adjustment frame. The expanding tube core head mold is installed, and the power supply is turned on to push the system.
The advantages of push system are: powerful power, infinitely variable speed, simple operation, safe and reliable, forming products with higher accuracy.
