A two-punch heading machine must reach 300-350 strokes per minute (normal number of strokes) during normal production and use. Any one-stroke jitter and offset can cause broken mold punching, product deformation, etc. This results in an increase in scrap rate and mold scrap rate; this increases production costs, reduces capacity and equipment utilization, and may cause greater equipment failure. Our effective experience is: from the same batch of impact treadmills, choose one piece of finished steel plate that is temporarily matched with the same batch, and use this component as the uniform standard tire for the batch grinding and scraping the table. Carry out the research of the batch (the corresponding number) of the body. After the completion of the research and distribution work, the steel plate on the impact running platform (assembly) used as the tire is removed and assembled to the orbital surface of the platform. This process greatly improves the precision of the research. It will not cause any waste of cost; the same batch of the platform and the impact treadmill can achieve maximum exchange.
Like general Automatic Sliding Door operators, Ningbo GDoor Automatic Curved Sliding Door operators have supporting beams, running carriage sets, idle pulleys, back up battery, electronic mechanical locks, switches, etc.. The only difference is that automatic curved sliding door operators have curved supporting beams. And the interlock system for opening and closing achieves access control and energy saving. Interlock function upgrades the automatic curved sliding door into a security portal by a sophisticated coordination system of switches and sensors. And the double ID authentication and the video analysis system prevent forced accesses.

The key point in eliminating the problem of the above situation is how to effectively improve the matching precision of the track surface of the head machine and the impact running platform in the manufacturing assembly process. 
Generally, the manufacturer of the heading machine equipment often produces a tire with the same impact table (geometry size, shape and position accuracy) when it is equipped with the (grinding, shovel) body and the impact table assembly accuracy. Uniform standard for use; however, it must be considered that even if the above-mentioned components are processed and manufactured on a machining center (CNC), even if the same (CNC) machine is used to input the same set of geometric coordinate parameters, it will be processed. Different batches produce geometrical differences caused by random factors such as clamping accuracy, initial zeroing accuracy, different materials, and tool wear conditions. This error is impossible to use after grinding and scraping. Eliminated in the assembly.
After the above process is realized, from the maintenance and user feedback information data, the precision of the stroke of the heading equipment in the production and use of the screw factory is greatly improved; the equipment utilization rate and the production efficiency are greatly improved; the mold breakage phenomenon is basically eliminated.
