Hollow piston cylinder, single-acting • spring clamping • hydraulic unclamping

Applications: un-pressurized long-term clamping of dies or fixtures on press beds and rams when the space available is limited T-bolt

Function:

Spring clamping cylinder

Manual positioning of the cylinder on the die clamping edge. Unclamping is carried out by applying hydraulic pressure to the piston, clamping takes place by spring power. By means of the T-bolt the die is clamped against the clamping surface of the press ram or bed. Special features: hydraulic supply is only required for unclamping, i.e. for a short time

spring clamping

ideal power transmission convenient and compact design with gripping surface no colliding edges, smooth die positioning suitable for retrofit easy fastening

Hollow piston cylinder, single-acting versions

Version with a total stroke of 20 mm   



Anti-twist protection

Optimum adaptation to varying heights of the clamping edges of dies by an increased total stroke of 20 mm (higher total stroke on request). Technical design, clamping forces and dimensions correspond to the standard in catalog sheet 3.2130. Due to the increased total stroke, dimension ‘b‘ is greater than indicated in catalog sheet 3.2130.







Spherical disk as an option

Total stroke 20 mm: Dimension ‘b‘ with a clamping force of 60 kN: 120 mm Dimension ‘b‘ with a clamping force of 104 kN: 132 mm

Die clamping edge







Web height

Stroke 20 mm











Version with variable clamping dimension  Counter nut









Through-hole 



Spherical disk as an option

Technical design, clamping forces and dimensions are as shown on catalog sheet 3.2130 for the standard design.



Die clamping edge



Web height

Stroke 12 mm











Freely adjustable and flexible adaptation to suit varying heights of clamping edges by rapid and easy adjustment of the tie rod using a counter nut. The tie rod is inserted through the hollow piston cylinder and adjusted to the correct dimension by means of the counter nut. In this version, the cylinder has a through-hole instead of a thread.



Safety information Increased risk of injury in the case of an incorrect adjustment of the version with higher total stroke or variable clamping dimension. The clamping stroke must be less than 6 mm.

Holder for hollow piston cylinders, inch

Application Used as parking stations for hollow piston cylinders with t-bolts. The holder allows the cylinder to be clamped and held in place when not in use. It can be used on the bed or slide. The hanger is a formed metal bracket, without the clamp plates, which allows the clamp to be temporarily stored during die change. The hanger is an alternate choice for bed clamps. Description The holder assembly includes a mounting bracket, clamp plates and clamp retainer pins. The hanger includes the mounting bracket and the clamp retainer pins. Advantages easy clamp storage during die change clamps not being used while the press is in operation, can be safely clamped in the holder Holders with integral check valve, special and metric versions on request.
