JB-2014 type automatic upset forging machine

JB-2014 type automatic threading machine 

Machine specification table :

Upset forging parallel thread rebar coupler matches with automatic machinery process, the size is 12mm-40mm. At the same time, according requirements of customers, it can be customized. If you need rebar couplers, please click on the following picture enter into the rebar coupler understand and choose:

The strength of rebar coupler can be designed according the requirements of customers, or the standard value and different parameter provided by customers, rebar coupler can satisfy:

1. Upset forging parallel thread connection is 100% higher than steel bar raw material, reinforcement connection belongs to the world’s highest standard requirements.

2. Satisfy: American ACI-318, British BS4449, France and other world’s highest quality inspection.

After finishing rebar connection, the tensile strength is 700-1050MPA, yield strength is 500-800MPA.  

Test result is 100% higher than steel bar raw material standard, tensile test is bar break, and the joint of rebar coupler is well.

JBCZ upset forging parallel thread connection is 100% higher than steel bar material strength , rebar connection belongs to the world’s highest standard requirements, satisfy: American ACI-318, British BS4449, France and other world’s highest quality inspection.

After finishing rebar connection, the tensile strength is 700-1050MPA, yield strength is 500-800MPA. 

I There are many types of connection , satisfy each connection request on job site: 

Standard type, this connection type is suitable for 80% projects.

II.Reducing rebar coupler connection, suitable for the change between story , for example , the basement adopt 32mm rebar , the story use 25mm rebar , it need reducing coupler in this situation , 

one end connect 32mm , another end connect 25mm , satisfy rebar connection in different sizes.

III.Adding length coupler connection , this type of connection suitable for the situation that two reinforcing bars can’t be rotated , such as the rebar cage connection at job site , 

both of the rebars can’t be rotated, then this type of connection is the most suitable one.

First step , screw the full coupler onto the first bar

Second step , screw back the coupler onto the second bar 

Third step , finish the connection

Ⅳ.Left and right hand coupler connection , this type is suitable for the project that two rebars or one rebar can’t be rotated , the advantage is only need to rotate the coupler can finish the connection of two rebars. 

One end of rebar thread is right hand , the other end of rebar thread is left hand , the rebar thread match with coupler, tighten two rebars while rotate the coupler , the coupler size : 12mm to 40mm rebar connection range.

Ⅴ.Adding length with nut connection , it is the same principle as adding length coupler connection , suitable for connecting two reinforcing bars which can’t be rotated, use the nut to fix the coupler make it can’t move up and down. 

Ⅵ.Terminal coupler connection , this type is suitable for the embed project such as embedded column, wall embedded, all need this type , during the embedded , in order to prevent the concrete poured, each coupler will with one plastic cover to protect the thread of coupler . Product size satisfy : 12mm to 40mm rebar connection range. 

VII.Terminal coupler connection , this type is suitable for the embed project such as embedded column, wall embedded, all need this type , during the embedded , in order to prevent the concrete poured, each coupler will with one plastic cover to protect the thread of coupler . Product size satisfy : 12mm to 40mm rebar connection range. 

VIII.Half thread half press coupler connection , this type connection is suitable for the situation that one end of rebar has already poured into concrete and can’t be rotated. Product size satisfy: 12mm to 40mm rebar connection range.

VVI.Epoxy coated rebar connection . Epoxy couplers have been applied in the world’s first longest bridge—Hangzhou Bay Crossing Sea bridge , The world’s second largest water pump station in Jeddah , Saudi Arabia.
