Shearing Press for Steel Plate |
 |
| |
|
|
| |
Customer: Mosley Machine
 Problem: Customer had two Problems: Clearance did not permit use of conventional tools and; severe shock and vibration from shearing operation would preclude use of conventional tools even if they did fit the application.
Solution: Biach developed a special compact tool that fit the limited space and provided the high stud loading requirement. |

Plate Assembly - Hydraulic Presses And Rolling Mills |
|
| |
|
|
| |
 Problem: Customers had difficulty assembling plates and running nuts into place. Frequently they faced lengthy times in nut running or disassembly of the equipment.
Solution: Biach designed a special "Split Nut" that could be quickly and easily inserted after the plates had been stacked. By splitting the nut in half and incorporating a hinge concept, the workers did not face excessive time in screwing the nut over long bolts or threaded rods. |

Production Line - Film Fixture |
|
| |
|
|
| |
Customer: Eastman Kodak
 Problem: Customer needed an accurate yet easy-to-use method for use in film production line. Repeatable loads were important.
Solution: Biach personnel worked closely with Kodak engineers to design a special tensioner for their project. The unit was made from Titanium and incorporated an internal spring return system, positive stop, special knurled puller bar for easy gripping, and a torque limiter on the drive gear. It was particularly important to make the system easy to operate. The puller bar was designed to "drop on" and engage the stud (1/2" - 20) with a quarter turn. Additionally, we provided a special electric pumping unit, for glycerine fluid operation, with remote controls. This unit incorporated special valving for accurate low pressure use.

Harrow Disc Assembly |
|
| |
|
|
| |
Customer: John Deere
 Problem: Harrow disc assemblies which had been torqued on customer's automatic assembly line came loose and fell apart while being transported by rail a few hundred yards to another building. Knowing what would happen when these assemblies were used in the field, prompted their engineers to search for a dependable bolt-up method.
Solution: Biach provided tools for their assembly line which applied a hydraulically actuated axial load followed by a pneumatically powered nut seating device. Speed of operation, ease in handling and output capacity were important concerns. |
