- Page 2 Hilma-Römhelld swing clamping elements are designed for a large number of clamping applications, in connection with screw or tie rods or T-bolt supports. Swing clamping cylinders type 2170 are particularly suited for the clamping of dies on presses when standardised dies with clamping slots or Hilma- clamping flanges are used.
- Page 3 O p e r a t i n g i n s t r u c t i o n s 2 Design and function Design The swing sink clamping elements consist of the housing, which accommodates the swing mechanism for the piston, inductive proximity switches for monitoring the unclamping, and clamping position and the piston with the tie rod.
- Page 4 O p e r a t i n g i n s t r u c t i o n s 2.2.1 Monitoring of tie rod position In order to ensure safe functioning of the swing clamping elements it is necessary to monitor the unclamping, change-over and clamping position, so that signals for die change and machine operation are available and any malfunction is indicated immediately.

- Page 6 O p e r a t i n g i n s t r u c t i o n s 4 Installation, connection and putting into operation Storage and transport During transportation, clamping elements must be protected against mechanical damage. For medium term storage, they should be kept in a closed dry space.
- Page 7 O p e r a t i n g i n s t r u c t i o n s Controls 4.4.1 Hydraulic and electrical controls The swing clamping elements are controlled by a power unit which, for reasons of safety, is completely separated from the hydraulic system of the machine.
- Page 8 O p e r a t i n g i n s t r u c t i o n s 4.4.3 Safety levels Although malfunctions seldom occur on hydraulic quick clamping systems, failure of a component cannot be completely excluded. In order to avoid the consequences of such a failure having an impact on the clamping safety, three safety levels are provided, and at least two of them should be installed.

O p e r a t i n g i n s t r u c t i o n s In order to protect the dies and the swing clamping elements, the correct die position must be monitored by a proximity switch. - Page 10 Remedial action Check the electrical installation and the swing sink clamping element, have it repaired by HILMA experts, if necessary If the guide pin has disengaged, take a hexagon tool to turn it in the correct position. (see chapter 2.2.2)
- Page 11 For the list of spare parts and installation drawings, please refer to chapter 7 (Technical appendix) and note the general information of the Hilma Catalog and the details of the swing clamping element data sheet. After replacing a clamping element, move the new element several times in order to bleed the system through the pump unit (the same applies if hydraulic connections have been disconnected).
