Product description

The hydraulic counterblow hammer GH is considered for heavy parts demanding blow energies of more than 160 kJ.

LASCO was pioneer and inventor of the hydraulic drive system for die forging hammers.

Counterblow hammers have an upper and a lower ram, which are accelerated towards each other. The ratio of mass of upper and lower ram is between 1:4 to 1:5 depending on the hammer size.
As a result, the lower ram moves between 4 to 5 times more slowly than the upper ram, delivering an impact speed of about 6 m/s.

Construction features:

Accurate repeatability of blow energy

Low energy costs compared with air driven units

Automation facilitated by the small stroke and the slower speed of the lower ram

May be mounted on direct spring damping elements

Hydraulic drive in block design in the hammer head

Programmable control system with operator guidance, product data administration and modem for remote diagnostics

Capacities: Blow energy from 63 kJ to 630 kJ

Fully automated stretching unit AR

Fully automated stretching unit AR: Consists of a stretching manipulator in combination with a hydraulic multipurpose press, used for making difficult pre-forms in small quantities. Compared with rolling machines, stretch forming is accomplished with simple and low cost tools, which are very versatile ...read more

Electro upsetters EH/EV

Electro up-setting combines heating and gathering of bar material in one process. The practical limits of mechanical upsetting are overcome by electro up-setting. For example, with automotive valves, the ratio of material in head to bar diameter may be as high as 20, and can be gathered in one cycle ...read more

Cross wedge roll QKW

QKW Cross-wedge roll: Cross-wedge rolls are utilised for pre-forming of round billets for subsequent forging, as well as for the near-net-shape production of stepped shafts, and similar symmetrical parts. The rolls driven by two electronically synchronised high torque motors and coupled with low ...read more

Hydraulic multipurpose presses VP/VPA/VPE

The VP/VPA/VPE series embody features which make them suitable for a wide range of applications and options, including automation. VP presses may be considered for scale breaking, upsetting, edge-breaking, pre-forming, material distribution, trimming, and piercing operations, which will necessitate ...read more

Screw presses SPR/SPP

Screw presses with direct electric drive SPR/SPP have applications for forming, straightening, calibrating, parts made of steel, high-alloy materials and non-ferrous metals. Screw presses with direct drive have the rotor of the drive motor connected directly to the flywheel and screw. Lasco SPR ...read more

Die forging hammer HO-U

From a technical and economic point of view, the forging hammer remains an ideal forming unit for the forging industry. A hydraulic hammer delivers maximum forming force with minimum energy consumption, ideal characteristics for forging a wide range of parts. LASCO is the inventor and pioneer of ...read more
