            Pressbrake Tooling Design And Production

                Bending machine die damage refers to die cracking, breaking and expansion. To deal with the problem of bending machine die damage, we must find the reason from the aspects of bending machine die design, manufacturing process and die use.

                <em id="jobjhfj6" style="display:none !important"></em><rp id="bui6lxv5" style="display:none !important"><legend id="jif6jkzl" style="display:none !important"></legend></rp><big id="x8z665df" style="display:none !important"><td id="vt45k6df" style="display:none !important"></td></big>

                  First of all, it is necessary to review whether the manufacturing materials of the bending machine die are appropriate and whether the corresponding hot burying process is reasonable. Generally, the heat treatment process of die material has a great influence on it. If the quenching temperature of the die is too high, the quenching method and time are unreasonable, and the tempering times, temperature and elbow are improperly selected, the die of the bending machine will be damaged after entering the bending production. The size or depth of the blanking hole is not designed enough, which is easy to block the slot hole and damage the blanking plate. If the spring force design is too small or the equal height sleeve is unequal, the spring will break and the blanking plate will tilt, resulting in overlapping punching and damage to parts. Improper fixation of the punch or insufficient strength of the screw will cause the punch to fall or break.

                  <th id="xxqbrv1a" style="display:none !important"></th>

                    When the bending machine die is used, the position and direction of parts are installed incorrectly or the bolts are not fastened well. The working height of the guide post is adjusted too low. Failure of feeding equipment and abnormal press will cause damage to the die. If foreign matters enter the mold, parts overlap, waste blocking and other situations are not handled in time and continue processing and production, it is easy to damage the blanking plate, punch, lower formwork and guide post of the mold.

                          In the bending process, once the die of the bending machine is inflexible or even stuck, the production must be stopped immediately to find out the cause of die clamping and eliminate the fault. Otherwise, it will expand the fault and cause damage to the bending machine die.

                              <noframes id="9clxfbmp" style="display:none !important">

                                          The main causes of die clamping are: poor die guidance and inclination. Or there are foreign matters between the formwork, so that the formwork cannot be pasted flat; The strength design of the die is insufficient or the stress is uneven. Cause mold deformation, for example, the hardness and thickness of mold base and template are too small, which is easy to be impacted and deformed by external force; The mold position is not installed correctly, and the positioning error of the upper and lower molds is out of tolerance. Or the accuracy of the press is too poor, resulting in interference of the die; The strength of the punch is not enough and the position of the size punch is too close, which makes the lateral force of the die unbalanced. At this time, the punch strength should be improved to enhance the guidance and protection of the discharge plate.

                                              Pressbrake tools testing  and adjustment is the last process in mold manufacturing. Its main work is to make up for the defects in mold design and manufacturing and the experimental production of qualified parts. Therefore, the relationship between bending tools adjustment and design, manufacturing, inspection and process departments is very extensive. In professional tools factories and large tooling manufacturers, there are sections or teams specially responsible for adjusting the press brake tools, while in small factories, tooling manufacturers generally adjust and test the mold together with the design and inspection departments. These departments have a close relationship and jointly identify the quality of press brake tooling.
