CRIMPING MACHINES
Crimping machines designed for permanent assembly of fittings on hydraulic and industrial hoses by crimping the ferrule on a specially constructed hose tail of a fitting. Many types of different crimping machines are present on the market - from simple manual crimpers to king crimpers with crimping force of 1,200 tons. All crimping machines are adapted to work with exchangeable die sets (different sets for different diameter range). The most important crimping machines parameters are: crimping range, crimping force, maximum dies opening and theoretical effectiveness (in crimps per hour). Available in manual, pneumatic or electric drive with different control systems.
CUTTING MACHINES
Cutting machines, with electric drive, designed to cut hydraulic hoses with steel or textile braid as well as some industrial hoses. Equipped with standard (smooth) or toothed cutting blades with 2900 r.p.m. speed of rotation. Hose is manually (lever), pneumatically or hydraulically (foot-lever) pressed against the blade. The most important cutting machines parameters are: hose external diameter, type of hose to be cut, type of motor, drive and available accessories such as e.g. hose boss, cuts counter and length measuring unit. Automatic machines, that cut a certain length of the hose, are used for multi series production.
MACHINES FOR INSERTING FITTINGS
Skiving of external or internal layer of certain types of hydraulic rubber hoses is needed before crimping takes place. For that purpose simple manual or semi-automatic skiving machines were developed. Equipped with skiving knifes adjusted to hoses nominal diameter.
Process of inserting fittings into hoses can also be mechanised. For that purpose inserting fittings machines with pneumatic drive were designed. Such machines reduce assembly time and are very often integrated with multifunctional machines used for multi series production.
TESTING BENCHES
Testing of hydraulic hose assemblies with static pressure is a final hose assembly inspection for leak tightness and strength. For standard testing of hydraulic hoses 2 x working pressure is applied. Testing is conducted with static pressure and lasts for a dozens of seconds. Testing can be conducted on a part or 100% of certain production series. Testing benches are equipped with lockable testing tank in which one or a couple of hose assemblies can be tested simultaneously . Testing fluid is water, oil or oil emulsion.
Hose assembly testing with pulsating pressure according to hydraulic hose standards is conducted to determine the hose life in thousands of cycles. Such testing requires very complicated and expensive testing equipment.
