Bends round tubing from 1/2" to 2 1/2" diameter, square tubing up to 1 1/2", and up to 2" Schedule 40 pipe.
Built-in degree indicator makes it simple to make accurate, repeatable bends.
Anti-Spring back locking lever for better bend control.
Heavy-duty construction - pictured here with 1-1/2" diameter tubing. 1" x 8" frame bolts, frame and drive arms are CNC machined from 1" and 3/4" steel plate.
Engineered To Be Reliable! - Painstakingly designed to last for years in a hard working fabrication shop. The hydraulic cylinder swivels in a solid CNC machined steel block that pivots exactly at the cylinder's center, preventing side loads on the cylinder's internals. The pusher block, seen in the lower center of the above photo, employs a unique rotating design and a swiveling bronze wear block so that the cylinder will not experience any up or down loading.
Self Locking, Hydraulic Operation! - The Model 4 employs a 10 ton single acting spring return cylinder with a stroke of 10" to 14". It operates up to 4000 p.s.i. With the recommended 14" stroke cylinder, 90 degree bends can be accomplished in less than two complete strokes and 180 degree bends typically require only three strokes. The 10" stroke cylinder requires three strokes for a 90 degree bend and usually five for a 180 degree bend. During bending, neither the die set nor the workpiece needs to be reset or touched in any way until the bending operation is complete. Using the spring loaded anti-spring back lever, the Model 4 will lock the workpiece in position when the cylinder needs to be advanced to the next stroke position, therefore not allowing the workpiece to relax or shift in the bender. This makes possible much tighter radius bends in thinner wall material then can be accomplished on competing benders. Using a 14" stroke cylinder, the first bend stroke can be up to approximately 60 degrees. The second stroke will go to approximately 126 degrees. Bending speed is dependent upon the strength of the material being bent. Usually 6 to 10 degrees of bend per second will be realised. The 14" stroke cylinder takes 8 to 9 seconds to return from full extension. Add it all up and a typical 90 degree bend will take an effortless 20 to 25 seconds, depending on the operator's skill level. Note: Since the pump and cylinder used in the Model 4 is extremely popular, you may already have them. If so you wouldn't need to purchase these items. If you have any questions in regard to this please call for assistance.
AFFORDABLE! The Model 4 Bender Package does not include die sets or hydraulics
The Model 4 Bender does not include a pump which will need to be purchased separately. We offer both air/hydraulic and electric pumps.
