  1. Another Successful TCR Installation

    Leave a Comment

     

    TCR recently completed the installation of this servo production system for progressive dies. The press is an Aida 700 ton servo mechanical. Even though delivered with a generous stroke over 15” long and the optional double gear reduction to provide full tonnage .5” above BDC, the servo can still run progressive dies over 55 SPM. Installed for a large contract stamper, the servo press is paired with a Coe feed line, capable of running coils up to 30,000 lbs at 42” wide, and HSLA materials over .250” thick. The set up is extremely flexible to handle a very wide range of materials and forming high in the stroke.

    TCR provided integration of the line, with our signature high value touches to increase the lines uptime and productivity. TCR’s skilled trades team interfaced all of the system components and installed all of the needed accessory items to make the line fully functional.
    Guarding was done with great attention to the client’s needs. Each client has their own unique processes for getting parts and scrap out and each guarding solution needs to account for them all while remaining compliant and easy to use.

    A custom conveyor for part removal was designed and built by TCR. It provides extremely low maintenance over its lifetime enhancing the system’s uptime. Its belting dramatically outlasts traditional fabric belting, in most cases lasting several years before replacement.

    This part out conveyor is installed on a custom conveyor mount TCR designed and built, providing powered raise and lower and tool-less adjustment in and out of the die area. This allows rapid adjustment to reach smaller or larger tools, at the optimum height, with minimal set up time. One person can move it out for die change and back into position with no tools in less than a minute.

    A telescoping material support mounted to a vertical lift table provides rapid adjustment for set up reduction. It can be retracted for die change, and quickly moved out to meet the tool and adjusted vertically to match the passline height. The support allows for the extremely fast feed acceleration without buckling of the strip. This is a critically important detail that maximizes the full use of the press’s impressive speed.

    The scrap system utilizes a mechanical cross bar that is rocked back and forth by Mayfran International’s unique shuffle drive. This electric motor driven scrap system is extremely robust, providing many years of production with a remarkable track record for uptime. TCR has multiple clients with these systems installed with zero un-planned downtime for over 6 years and still counting.

  2. No Choice but to Automate

    TCR’s very own President Todd Wenzel was contacted for an interview recently by Metalfrom Magazine to discuss automation in the press room. It is both humbling and gratifying to learn that our work has had enough impact to draw attention like this and we appreciate the implicit compliment it represents.

    Our many vendor partner’s have been a significant part of our success in automation and we feel it would be remiss if we did not highlight them, for without their partnership we could not have made such a positive impact in automation for our clients.

    Thanks go out to AP&T, Aida, Machine Concepts, Link Systems, and Coe Press Room Equipment for their contributions to our work assisting clients become more competitive specifically when it comes to the application of automation in the press rooms we have been honored to work in. Thank you all for helping us help our clients with their growth efforts!

  3. Quality Matters for the Mechanics You Choose Too

    An Ounce of Prevention is Worth a Pound of Cure For Your Press Too

     

    While TCR’s mechanics were performing preventative maintenance inspections on our customer’s presses, they discovered a problem. The total stack-up clearance was excessive on one machine.  

     

    Total stack up clearance is a total of all the running clearances of the crank bearings, main bearing, slide adjustment mechanism and the ball or wrist pin connection to the ram. Think of it as a simple test that will either reveal if the machine’s connection clearances are correct, or quickly identify that something is wrong. 

     

    They then tested the individual clearances, anticipating one or more was worn. Indicators were used at each point in the connection to measure every bearing or clearance point individually. Surprisingly, it was determined that the clearance in the connecting rod itself were well within specifications.  

     

    Instead, they discovered that the fasteners between the adjustment screw mechanism and the ram were loose. Repairs by another company had been done recently, and the bolts were not properly secured upon completion of the work. Vibration from the stamping operation caused the bolts to loosen. 

     

    TCR service technicians cleaned and inspected the area and determined no damage had yet occurred. This was a pleasant surprise; the issue could have caused major damage to the machine and even endangered the operators. Our mechanics applied an appropriate thread locking sealant, torqued the bolts to specifications, and applied the tie wires to prevent the bolts from loosening in the future.

     

    The importance of a solid inspection press program cannot be overstated. Besides being required by OSHA (see \1910.217(e)(1) thru \1910.217(e)(3)), it is clearly a great investment for any manufacturer. 

     

    Because this customer chose to invest in preventative maintenance, we discovered the problem before the excessive clearance caused severe damage or unplanned downtime. If they were not committed to regular inspections by our mechanics, they would have had an expensive repair, who knows how much down time, and could even have injured a team member. 

     

    It is equally important to make sure you have skilled and knowledgeable technicians performing maintenance on your machinery. Are you sure your press vendor’s team are up to the task?

  4. Press Machines Mechanical Repair

    Another Repair by TCR’s Press Mechanics Has Been Completed

    This press had damaged back shaft bearings causing loud grinding; audible despite the other loud press room noises around it. Inspection revealed the bearings walking out of the housings and off the shaft.

    This failure was caused by someone doing a previous repair incorrectly. Our mechanics dropped the back shaft assembly and dismantled it. New bearings were installed, and the clutch/brake was rebuilt.

    At start-up, the customer said it sounded better than it had in years, but our team of mechanics still felt there was a suspicious noise coming from the press. They discovered the left main bearing was not getting enough lubrication. Fortunately, it was still in serviceable condition, so no replacement was required.

    Our mechanics increased the lubrication flow, and soon the noise disappeared completely. Our client was shocked at how quiet the press was and extremely happy with the results of the repair.

    What could have been an even more costly repair was averted, and the machine is now back in service and expected to be reliable once again for many more years.

    Keep up the great work, Team TCR!

  5. Additions to Mechanical Service Department

    Expanding The Service Department

    As promised, here is photographic evidence that the mechanics weren’t left behind!

     

    They received two new tool boxes along with another truck. Ironically, they have been too busy doing repairs for our clients to work on their own projects.

    Like our electricians, they shadowed their boxes; creating a spot for every tool. This increases their efficiency out on the road, but just as important–it looks really cool.

    They worked fast this week to get this done, because next week, they will be back out on the road. The next repair will be a clutch rebuild and bearing replacements.

    Stay tuned for new developments!

  6. TCR Continued Growth

    Expanding The Service Department

    Despite the challenges of 2020 TCR has continued to grow. Just this November we expanded by adding another service truck and upgrading our technician’s gear to improve efficiencies at the job site.

    Shown here are 1 of the electrician’s 2 new, heavy-duty toolboxes added to their arsenal.

     

     

    Our techs cut foam to match each tool. Like shadow boards by the press, these provide organization to save time finding tools. Every tool is in its place, and the crew always know where everything is. This not only organizes the tools, but also protects them from the vibration of riding on the road to and from our customers’ plants.

     

     

    The team is always on the lookout for new tools to make us more efficient. The new boxes provided room for what they added in the last year. We invest a lot in tools, but the return is faster work in the field so we can get our clients up and running quicker.

     

     

    With the growth of our mechanical repair department, we also needed to add a 3rd toolbox that was outfitted specifically for that team. This will increase our mechanical repair team’s efficiency as well. Stay tuned for more expansion news in the mechanical repair department.

     

     

    We at TCR are so excited about these new additions and can’t wait to send them out on the road!
