With the rapid development of society and economy, Longmen punch industry is still in the ascendant, and the demand for stamping technical personnel at all levels continues to grow. Therefore, how to teach and learn the course of stamping technology and die design has become a subject that many people have been painstakingly exploring. A suitable textbook is an important guide to learn cold stamping technology.

The core of learning stamping and die is to understand the process principle and grasp it in engineering practice. Beginners do not need to pay attention to all formulas and forms in this book, but should pay attention to combining theory with practice. First, they can understand the stamping forming qualitatively, and then analyze, summarize and master the basic application with formula and table after entering the perfect situation, Finally, we can grasp and apply it systematically.

The current of gantry punch is not reached on the basis of the value), and the flux increases. The electric frame absorbs the resistance of the spring and draws to the stator and makes the slide of the punch move. With the power failure of the circuit, the moving part of the gantry punch is returned to the original position under the action of spring. The sliding state and the surface of electromagnet frame are connected with each other quickly, which makes the bar of the press.

The electric operation roughness is an advanced operation of saddle. Because tapping the operation point can expand the use of gantry punch and improve its working reliability. It is worth noting that the rationality of the electromagnetic punch in the automatic operation upstairs is due to the reliability of its cross-section cover, punch and its electrical enemy preparation. Because of the high speed movement of sliding state, the possibility of application of electromagnetic punch in extrusion process should be indicated.

The creation of electromagnetic punch is prior to the research work carried out by the author and the working procedure of various electromagnets (motors used as the rod of the moving punch).

Whether the installation of gantry punch is appropriate and effective, not only endangers the quality of stamping die, but also harms the working life and safety production of grinding tools. Generally speaking, the installation process of stamping die is given.

(1) Check and verify grinding tools and gantry punch. Before installing the grinding tool, it is necessary to determine the specific model and specification of the press for the stamping die, and check whether the specification and working standard of the grinding tool are in accordance with the performance parameters of the specific press (the ratio of height to width of the loading die, the arrangement of the slide rail travel, etc.) of the press, and whether the press is in good condition.

(2) Eliminate all dirt or dirt in the bottom of the slide block of the press guide rail, the table surface of the gantry punch (or pad block) and the upper and upper die base plans of the grinding tools.

(3) Manually make the flywheel of press (or control the point key), adjust the upper guide rail slider to the upper dead point, and rotate the extruder screw to adjust the crankshaft length to the shortest (i.e. the closing height and width are relatively large).

(4) Place the closed grinding tool on the press operating platform or cushion block in a proper position. If air cushion CC is applied, the top bar shall be set first and the place of the grinding tool shall be marked.

(5) Manually make the flywheel (or control point) of the press to make the slide of the upper guide rail of the CNC lathe rise and stop at the lower dead point.

In order to meet the requirements of metal material stamping die manufacturing industry, Ningbo Gu'an Li punch manufacturer has produced more and more high speed and high precision punch. With the development trend of the sales market, the development of computer and the development trend of the speed change, the high speed gantry punch is now turning into a higher speed, high efficiency, full automatic, high precision, special type and various production and manufacturing directions.
