Upsetting Rebar Coupler Suppliers and Manufacturers

Advantages: Bar-break feature guarantees fully ductile elongation. No reduction of the bar cross-section area. Working principle: 1, first, we use gq50 rebar cutting machine to splice up the end of rebar. 2, secondly, we use upset forging parallel thread machine (bdc-auto1 machine) to forge the end of rebar. 3.Third, we use parallel thread cutting machine (lw-i500 machine) to thread the ends of the rebar which have been forged. 4.Fourth, an upsetting coupler is used to link the two ends of rebar in parallel thread.

The parameters of standard Upsetting couplers : Size 16 18 20 22 25 28 32 36 40 Material of the rebar coupler is No.45 steel.

Upset Forging Rebar Coupler with rebar upset forging machine, tensile could get to 800Mpa standard rebar coupler

Upset Parallel Threaded Rebar Coupler 100% bar break through tensile test. Material of the rebar coupler is No.45 steel. High precision thread, full thread type, no false thread.

Features 1. Hydraulic full-automatic, fast speed. 2. Cutting thread on forged bar with chaser, threading diameter 16-40mm(upsetting M20-M45mm). 3. Strength of the joint is higher than the rebar material. 4. Thread is full enough, max. threading length is 150mm. 6. Thread pitch is from 2.0 to 4.5mm with high accuracy.

Advantages 1. Double cylinder, vertical cylinder is for clamping rebar, horizontal cylinder is for forging. And the two cylinders are almost move together, so forged speed is very high, 25mm rebar forged only 8-10 seconds will be finished. 2. Large cylinder outer diameter, so that large torque, 250mm/300mm (vertical cylinder/horizontal cylinder), easy to forging 40mm steel bar, and even up to 43mm steel bar, one of our clients tested 43mm bar with AGD-40 few month ago. 3. During the upsetting forged process, the male mold will not enter into the female mold, so male mold could be large enough. So that it will not be damaged frequently, (one of our clients upsetting forged 8600pcs 540MPA rebar, but it looks like original), and the forged head is complete and full, there is no deviation, so next step of screw cutting will be very accurate, and could increase your service life of chaser on thread cutting machine. 4. The mold is easy to replace, and only need to replace female mold to matching different size rebar, loosen the each 4 screws on the upper and lower molds, (AGD-40L type, press 'Replace Mold' button, then loosen the 4 screws on the lower mold), and then backward the horizontal cylinder to the end position of the cylinder, the old mold can be taken out at the top of the horizontal cylinder. 5. Automatic Counting Function can be displayed on the screen, to conveniently statistic working efficiency of workers (AGD-40L). 6. If you feel that the forged end is not full/too full, only adjust the horizontal cylinder's distance(initial position), but no need to adjust the pressure. 7. After setting the steel bar size on the machine once, you only need to press the foot switch for each time, no need to set it again, until the whole machine powered off.
