Automatic prestressing and testing machine SP-1

A prestressing machine with automatic feeder and load measuring for one spring length and three-way sorting for load ranges up to 100 N.

The vibratory feeder brings the springs in a vertical tube. A feed device even lets one spring pass the tube and feeds a round transport table which has six holes to hold the testing parts and gets moved step-by-step in clockwise direction. Having passed the feeder the springs are moved to the certain prestressing units followed by a measuring unit with an adjustable in-feed length. Having passed all the units the springs are sorted in three definable groups.

Technical data:
max. setting load: 200 N
max. load range:100 N
max. spring length: 80 mm
max. spring dia: 28 mm

Automatic prestressing and testing machine SP-2

Prestressing machine with automatic feeder or feeding by hand and load measuring for one spring length and three-way or five-way sorting with loads up to 1000 N. There are three prestressing units mountable.
Measuring of L0 and block is optionally available.

A vibratory feeder or manual feeding brings the springs in a vertical tube. A feed device even lets one spring pass the tube and feeds a round transport table which has eight holes to hold the testing parts and moves step-by-step in clockwise direction. Having passed the feeder the springs are moved to the certain prestressing units followed by a measuring unit with an adjustable in-feed length. Having passed all the units the springs are sorted in three or five definable groups.

Technical data:
max. setting load: 2000N max.
load range: 1000N
max. spring length: 80 mm
max. spring dia: 28 mm
max. speed: 3.000 parts per hour

Included load ranges:

load range 1: 0 - 20 N
Resolution 0,01 N

load range 2: 0 - 200 N
Resolution 0,1 N
load range 3:
0 - 1000 N
Resolution 1 N

Other load ranges are available.
