WH-350 WELD SQUEEZE BOX DESTINED FOR OHIO

 


Yoder Manufacturing of Cleveland, Ohio, a member of the Formtek Group, has recently been contracted to refurbish and upgrade an existing WH-350 tube mill to produce structural shapes (HSS).  Formtek has designed a new style weld squeeze box that consists of a five (5) roll and four (4) roll configuration as deemed necessary by the particular product being produced.  Either configuration utilizes a top head roll assembly consisting of two (2) top edge rolls that control the edge presentation prior to welding.  The head roll assembly has vertical adjust as a group and individual adjustments to compensate for improper strip edge alignment.  The main squeeze pressure is provided by the bottom squeeze unit which will utilize two (2) side rolls only for rounds that range from 1.500” to 3.250” (38.1 to 82.6 mm) OD or two (2) side rolls and one (1) bottom roll for rounds that range from 3.250” to 5.000” (82.6 to 127.0 mm) OD.  With the ability to switch from 4-roll to 5-roll configuration allows the operator the utmost in flexibility to provide the proper material presentation for the welder.  The bottom squeeze roll assemblies are unique in that there is fast sides close adjustment as well as a fine tuned (and geared) close adjustment, thus eliminating the need for operators to utilize cheater bar tools, which can cause injury if they slip.  All roll spindles are “dead-shaft” design so the bearings are housed within the rolls to yield the best possible bearing life for the weld box, which is considered the worse case scenario for environment on the tube mill.


 The weld box assembly has one last feature that is the ability to move up and downstream with respect to the tube mill flow.  This allows the operator to fine tune the weld VEE angle with respect to the last fin-pass.  Therefore, depending on your particular tooling design, the weld VEE angle can be changed to gain the best operating parameters for your particular product.  The weld squeeze box assembly can handle up to wall thicknesses of 0.250” (6.4 mm).
