Jerhen Industries — Thread Rollers

They are designed for ease of operation and operator convenience, which means each thread roller features:

Exclusive patented feed-stop/trigger system to ensure "skid free" starts
Exclusive patented four-axis die adjustment and alignment system to ensure "lap free parts"
Exclusive integral, ram mounted, pneumatic parts blow-off to ensure positive part discharge
Exclusive feed rail height adjustment system
NC variable speed drive to eliminate problems associated with sheaves, belts, and transmissions common on competitive system designs
Heavy-duty ram and ram pocket that incorporates hardened steel wear plates on AMPCO bronze wear liners with an integral recirculating coolant system
Integral high-pressure lubrication system to ensure consistent lubrication during operation
Standard low-pressure shutoff to protect against plugged lubrication system
Positive hydraulic lock-down of sub-plates on WT-10, 20, & 30 — Belleville washers on all other models
WT-10, 20, & 30 includes hydraulic adjustment of feeder bowls
Removable coolant tank that can be easily moved to a remote location for cleaning, which eliminates the problems and mess associated with integrated tanks

Our patented four-axis setup adjustment is the key to unmatched precision and lap free thread quality. This system incorporates three sub-plates and a tilt block, allowing precise positioning and alignment of the stationary die. Dial indicators located at each adjustment allow the operator to precisely align the die quickly and easily for each part change. This virtually eliminates lapping problems, which are common to other types of machine designs. Here’s how the four axis adjustments work:

Die Match: The bottom sub-plate allows adjustment of the first axis for die match. The bottom sub-plate is moved by an adjusting screw, which features an integral graduated dial for precise adjustment.
Die Inclination (Finish Squeeze): The top two sub-plates provide adjustment for the second axis, which affects die inclination. Turning the adjusting screw causes the top two plates to position the leading edge of the stationary die. This adjustment determines the amount of penetration at the end of the rolling process.
Die Squeeze: The third axis, which determines the die squeeze at the start of the rolling process, is accomplished by adjusting the position of the top sub-plate.
Die Tilt (Optional): The fourth axis adjustment, mounted into the die tilt block, allows the die to be tilted for applications using tapered blanks.

Warren thread rollers are equipped with our unique feed-stop/trigger design to prevent multiple blanks entering the die at the same time. The combination feed-stop/trigger system controls blank forces at the rail tip, ensuring that only one part at a time enters the die area. To eliminate the possibility of damage from "rollback" during high-speed operation, the swing-away keeper assures complete control and alignment of the blanks as they enter the die. Should a "rollback" occur, the swing-away keeper is designed to automatically retract, preventing damage to the tooling. By combining these features with the industry's most versatile pusher arrangement, the Warren thread roller offers unchallenged ease of setup and the industry's most user-friendly operation.

Another unique feature of all Warren thread rollers is the utilization of a 45-degree insertion angle. This exclusive design feature allows very high production speeds while maintaining absolute precision and blank control. As a result, Warren thread rollers eliminate "blank skid" during startup, which is common with other thread rollers.

Optional Spiral Thread Detection: "Spiral threads" or "run-ups" are caused by parts not starting straight in the rolling dies. The optional Warren spiral head detection system detects the parts that rise as they advance along the stationary rolling die. It then shuts off the machine.
Feed Rail Features: Warren offers a feed rail design which increases operator efficiency, minimizes setup time, provides consistent feed control and precise part movement throughout the feed cycle.
Blank Head Clearance Adjustment: (Standard) The exclusive "flip-top" rail system is designed using a specially designed adjustment mechanism which allows the operator to quickly and accurately adjust the blank head clearance at both ends of the feed rails.
Clearing Jammed Feed Rail: (Standard) Warren's unique "breakaway" rail system design allows the operator to easily access and clear the feed rail in the event of a jam caused by an out-of-spec blank.
Adjustable Rail Height: (Optional) The height of both rails can be adjusted simultaneously using a single control lever with integral locknut.

Standard thread rolling practice applies when rolling maximum part diameters and lengths.

Model WT-1000/WT-1500 Warren thread rollers coupled with the Warren-Linread Model BW-2400 Assembler provides reliable, high-speed assembly of a wide variety of screw (or bolt) and washer combinations in one efficient, space-saving package.

This system provides total adjustability for reducing setup time. The integral 21" vibratory screw blank feeder has fully adjustable feed rails to provide maximum versatility and speed. Setup is accomplished quickly and requires only the adjustment of the screw blank fingers and the washer feed disc. If the screw blank diameter doesn't change, then you only change the washer feed disc.
