APPLICATIONS FOR BENCHTOP PNEUMATIC PRESSES

Joraco Press Company Designs Dual Press System for Wheel Hub Assembly For Leading Agriculture Solutions Provider

By combining our technical leadership in both pneumatic press engineering and industrial automation, Joraco Press Company built an automated press-fitting system for a leading manufacturer of tractors. This oversized press is engineered to press fit bolts into tractor wheel hubs with high precision.

This assembly system that includes two 8 Ton HYDRO-AIRE® Series hydro-pneumatic presses, incorporates an electric servo motor mounted on top of a pneumatically powered linear slide and an optical sensing system. As the operator loads the hub into the press with pins loosely inserted in the desired locations and activates the system, the linear slide moves the wheel into position. Guided by optical sensors, the servo motor rotates the wheel hub until one bolt is accurately located under each of the two presses. As the bolts are held in perfect alignment, the presses actuate simultaneously with a precise amount of force to insert them into the hub. The motor then rotates the next two bolts into position, and the process is repeated until all the bolts are inserted. The slide then retracts, and the part is manually ejected.

For maximum strength and rigidity, Joraco Press constructed the press from a combination of cold rolled steel and tool steel. With a footprint of only 45.0″ long x 24.0″ wide, the machine occupies just 7.5 square feet of floor space. A safety light curtain was integrated that protects operators from injuries related to machine motion.

Rivets are permanent fasteners that feature smooth cylindrical shafts with a head on one end. Manual installation requires the use of pre-punched or pre-drilled holes into which the rivet is inserted. Once it is in position, its exposed end is hammered to secure it in place. Riveting press machines serve as a modern alternative to manual riveting, allowing for easier, faster, and more consistent installation. They are available in many variations—such as manual feed or automatic feed—to suit different manufacturing applications. For Riveting Applications, we provide tubular/eyelet rivet machines built around our standard line of TOGGLE-AIRE® Series Pneumatic Presses. These machines offer the same reliability and ease of maintenance expected of us and give customers the convenience of interchangeable parts between the rivet machines and pneumatic press line.

Staking Workstation for Supplier of High Quality Laser Engraved Pet ID Tags

A supplier of high-quality laser engraved pet identification products approached Joraco Press Company about the possibility of furnishing a turnkey staking system for the forming of anodized metal into several specific dog tag profiles.

This turnkey workstation incorporates a staking press with custom tooling; a servo-powered rotary indexer and an air driven ejection system. After the operator loads blanks onto a rotary indexer with custom nests for each of the seven different profiles, the indexer moves the parts under the press where they are staked. Staked parts rotate to the ejection station where they are blown out of the nest by a pneumatic cylinder and into an ejection chute.

We built this automation system for continuous duty operation. At the customer site, it runs 24 hours/day for the mass production of pet identification tags with overall dimensions of 2.5″ in diameter x 0.1″ in thickness. The servo motor on the rotary indexer allows for flexible, high accuracy positioning to obtain repeatable accuracy of ±0.001″ on the finished tags. The customer was so impressed with the speed, accuracy, and repeatability of this system that they placed an order for four additional machines.

Joraco Press Company Manufactures a Hydro-Pneumatic Press for Use in the Pyrotechnic Industry

Joraco Press Company, a premier manufacturer of pneumatic presses, was approached by a company well-known in the pyrotechnic industry to provide a press that would enhance the production of their unique product line. This particular application called for the ability to compress volatile material within a form to a specific density. This is not the first time that an Joraco Press was chosen for an application that called for the compression of explosive material and they were excited to gain more exposure in this field.

Joraco Press's HYDRO-AIRE Series offers clean, reliable and accurate results with presses ranging in capacity from 4 to 30-tons of force. This air-over-oil series is a much cleaner alternative to a hydraulic press and offers the same advantages. It is fully contained with no fluid reservoirs or hydraulic lines, and features rapid advance with an automatic power stroke.

The customer was pleased with the arrival of their 8 ton HYDRO-AIRE Series Model HP8 press. Not only was it delivered in the nick of time, but it also worked out of the crate just as it was intended to do. They received our press with a narrow window of time before they were schedule to meet with clients to test the manufacturing process utilizing it, but their confidence was assured quickly upon its arrival at their facility. Much like our customers, Joraco Press Company also strives to produce high quality products that perform as advertised.

Joraco Press Company Provides a Solution for Specialty Filter Manufacturer With Their TOGGLE-AIRE® Series Model 3530 Press

At Joraco Press Company, we provided a top manufacturer of specialty filters with a turnkey solution for a technically sophisticated punching application. Automated Industrial machine, Inc and Joraco Press Company's  automation specialists worked together to engineer and manufacture a product that would comply with strict clean room standards and was based on Joraco’s 16 ton TOGGLE-AIRE® Series Model 3530 design. The solution also incorporates an INDEX-AIRE Series Model 1011RT servo-indexed rotary indexer and an optical sensing system for quality control. The dimensions occupy a compact 33.75″ x 20.0″ footprint and stands 65.0″ high, which is the same used in the production stainless steel mesh filters for an aerospace application.

The Model 3530 is capable of producing over 36,000lbs of force at 100PSI. It operates on 50 to 125lbs of air pressure with a repeatability of +/- .001” and capable of up to 80 stokes per minute. It has low air consumption and a controlled squeeze to over 20,000 lbs. at 80 psi. There are replaceable bronze/PTFE bushings used throughout the entire linkage assembly and the 8” x 10” precision ground bolster plate is removable to accommodate tooling requirements. This equipment punches extremely small, difficult to manipulate woven and pleated stainless-steel mesh sheets. The machine loads the mesh into nests on a rotary indexer, and as the indexer rotates, a vision system verifies that the part is loaded and oriented correctly. If the mesh is seated properly, the press actuates and punches a hole in the sheet. A second automated vision system takes measurements and monitors tolerances, and if a part is defective, it is ejected into a separate bin.

AIM and Joraco's solution significantly enhanced the manufacturing process of the manufacturer. By implementing the first optical sensing systems to provide feedback on part presence and orientation and the second to assess quality, we automated the entire process. The stainless steel, clean room compatible construction eliminates the possibility of contamination leaking into the manufacturing area and compromising the integrity of filters as they are processed.

Joraco Press Company's Punch & Shear Application Using Servo Driven Feeder

Joraco Press designed and built the fully automated multi-press punch and shear system for the manufacturing of transformer core sheets. It featured two high-accuracy 10-ton TOGGLE-AIRE® Series Model 2530 pneumatic presses, one for punching the hole and the other for shearing the sheet. The primary challenge of this project involved obtaining precise tolerances of ±0.002″ around the burr of the punched hole on the steel sheet. To ensure dimensional accuracy in the customer’s stack core transformer design, our engineers had to design, build, and exhaustively test the punch tools to ensure they repeatably produced holes with the correct size and shape.

Constructed from cold rolled steel for strength and rigidity, the automated punch and shear system features a space-saving 29.5″ long x 30.75″ footprint. Along with the two presses, it incorporated a servo feed that delivers precise positioning accuracy and enables the press to produce consistent parts with close tolerances at fast operating speeds. The punch and shear system also included an integrated PLC system that was fully programmed and ready to run as soon as the customer loaded up the material.

Joraco Press Company supplied this automated fabrication system with a precision sharpened carbide tooling package. The tooling successfully obtains precise tolerances, and with carbide’s ability to maintain its cutting edge, even during high speed punching, it produces accurate parts over long production runs.
