Longmen punch manufacturer will show you the types and specifications of gantry punch equipment and selection methods. In the production of small and medium-sized stamping parts, open punch is mainly used. The single column punch of Longmen punch manufacturer has convenient operation conditions, easy to install mechanical accessory device, and the cost is low; The open punch has the advantages of feeding and discharging in the left and right directions. However, the stiffness of this kind of punch is poor, and the deformation of the bed body under the action of the press deformation force can destroy the gap distribution of the punch. Reduce die life or surface quality of blanking parts. In the production of large and medium-sized stamping parts, the closed press is used. Among them, there are general-purpose press, but also have small table and large rigidity of special extrusion press, precision press, etc. In the production of large drawing parts, double acting press can be selected. The mould structure is simple and easy to adjust.

In the mass production of gantry punch or large-scale production of complex parts, high-speed press or multi station automatic pressure pickling shall be selected; In small batch production, especially in the bending and forming of large-scale thick sheet stamping parts, high-speed press or friction press are often used. Hydraulic press has no I.Q fixed stroke, and will not overload due to the change of sheet thickness. When a large force stroke is needed, it has obvious advantages compared with punch. However, the production rate of hydraulic press is low, and the dimension precision of stamping parts is not very stable due to the influence of operation factors. Friction press is simple in structure, low in cost, and is not easy to be damaged by overload. It is often used for farmers to complete bending and other stamping work. Because the stroke of friction press is not fixed, it can keep stable accuracy in the process of sheet thickness fluctuation in the flatness or shape adjustment of stamping parts. However, the friction press has less travel times, low production rate and inconvenient operation.

The development of stamping technology of high-speed press: the main version of process analysis is modernized, and the high-speed punch technology integrates the manufacturing cycle, saving a lot of labor and time. The improvement of the design quality of the high speed press die. In order to meet the needs of a large number of production, the high-speed punch production has been developed to automation and unmanned. Now, the high-speed press is used to realize the automatic single machine, and the stamping speed can reach thousands of times per minute. The production of large-scale parts has been combined with multi machine production line, which is controlled by computer from feeding, stamping and post inspection of sheet metal, reducing labor intensity of workers and improving production rate. At present, stamping production has gradually developed into the flexible stamping process formed by unmanned production.
