Intermediate frequency hydraulic pusher

The pushing machine is double cylinder or four cylinder average speed forward, the pump station valve station adopts the integrated form.The pump station is composed of multiple levels. There are 2-3 pumps for the first to the sixth specifications of the equipment, and 1 pump station for the eighth specifications of the bending test equipment. A historical background of quick return of books and periodicals is set.

The pusher is divided into two forms of one - time push - elbow and three - time push - elbow, hydraulic two - time push - pipe bender. The total stroke of standard type can be directly customized according to the requirements of users.

The material on the pusher is driven by the feeding machine to pull the steel wire rope, pipe pusher and steel wire rope wheel to send the original pipe to be expanded into the equipment.

If power supply is installed in the front of the equipment, if induction coil is secured on the adjustment rack, top the mold of the core head of the expanding tube, turn on the power supply, and push the system.

The advantages of pushing are: strong power, stepless speed change, simple operation, safety and reliability, higher precision of forming products.

Elbow mechanism manufacturer

The main purpose of elbow machine is: elbow machine is the installation equipment to produce elbow, can produce diameter 21-1620mm, wall thickness 3-100mm, elbow multiple is more than 1D carbon steel, alloy steel and other materials.

The technology of elbow production by elbow machine is to adopt special elbow machine, mandrel and heating device. The precision seamless steel tube makes the blank on the mold move forward under the push of elbow machine. During the movement, it is heated, expanded and formed by bending.

Hot push bend deformation characteristics is determined according to laws of the metal material volume before and after plastic pipe diameter, pipe diameter bend diameter, through the core module and control the deformation of the process, make the inner arc compressed metal flow, the compensation to other parts of the thinned by expanding, resulting in wall thickness of the elbow.

The hot push elbow forming process has the functions of beautiful appearance, uniform wall thickness and continuous operation, which is suitable for mass production. Therefore, it has become the main forming method for carbon steel and alloy steel elbows, and is also used in the forming of stainless steel elbows of some specifications.
