ZTRFM Hydraulic Bending machine mold structure classification
ZTRFM hydraulic bending machine molds are auxiliary tools used by ZTRFM hydraulic bending machines to form sheets and process sheet materials. This tool is composed of various parts, and different molds are made up of different parts and shapes. It mainly achieves the shape change processing of material items (mainly metal plates) by altering the physical state of the formed material through the pressure of the ZTRFM hydraulic bending machine , thereby enabling the material items to obtain the shape we need.
ZTRFM hydraulic bending machine molds can be structurally divided into two major categories: upper molds and lower molds. The vast majority have the upper die as the active die (the upper die moves, which we can call the moving die), and the lower die as the passive die (the lower die does not move, which we can call the fixed die). However, there are also some that are opposite due to the different working modes of the ZTRFM hydraulic bending machine , but the overall form remains unchanged.
Metal bending machine molds can generally be classified into standard molds and special molds based on their usage. The general standard upper mold tool tip Angle is 30 degrees (actual Angle 26-28 degrees), 60 degrees, 78 degrees -88 degrees, etc. The lower mold groove Angle is approximately 30 degrees, 45 degrees, 60 degrees, 80 degrees -90 degrees, etc.
If classified by shape, the upper die of a ZTRFM hydraulic bending machine can be divided into sharp die, arc die, curved die and forming die. Usually, the Angle of the sharp knife mold is mostly 30 degrees and 60 degrees. Occasionally, there are also special specified angles such as 45 degrees and 55 degrees. The arc die is mainly designed based on the diameter and length of the arc, and so on. The bending die is mainly used for avoiding some "U" -shaped workpieces or in multi-pass bending. The most complex part is the forming mold, which can be either an integrated type or a combined type. Generally speaking, combined molds are designed and manufactured together with the upper and lower molds, and are used as a set. In terms of production cost, the manufacturing cost of one-piece forming molds is relatively much higher (especially for large-sized molds), and the precision is also difficult to control. Combined molds have significant advantages in large-sized molds and complex graphic molds.
ZTRFM hydraulic bending machine molds can be classified by function into single molds and multi-functional molds. A single mold can only process a single type of workpiece, while a multi-functional mold can process different types of workpieces. Some can be disassembled and assembled, which we also call compound molds, such as differential molds and forming molds.
The lower mold of a ZTRFM hydraulic bending machine can be roughly classified into single V mold, double V mold and multi-V mold based on the number of mold slots. Single V-moldsand double V-molds, as the names suggest, have only one or two die slots on their surface. They are commonly seen in CNC ZTRFM hydraulic bending machine s and have relatively high precision because they have a fixed reference. We also call them concentric molds and they can be freely interchanged. Most multi-V lower molds are square molds. Each of their four surfaces has several die grooves of different sizes. The advantage lies in the large number of die grooves, which can adapt to the bending of sheet materials of various thicknesses.
Nowadays, with the continuous progress of society, the requirements for products are also constantly increasing. Therefore, various requirements for bent finished products and materials are also constantly rising. The lower die of the ZTRFM hydraulic bending machine is also constantly developing. Inlaid lower molds, cremless lower molds, and adjustable opening lower moldshave been widely used in all walks of life.
1. The inlaid lower die is mainly designed to enhance the utilization rate of die materials or be applied to the bending of special materials.
2. The types of crease-free lower molds include ball type crease-free lower molds, flap type crease-free lower molds, and Youli adhesive crease-free lower molds. The non-indentation lower die mainly eliminates the possibility of scratches, abrasions and indentations on the material surface.
3. The open adjustable lower die comes in several types, including insert type, pair insert type, wedge type and rack type. The adjustable lower die with an open opening not only enhances the utilization rate of mold materials but also significantly improves work efficiency, reducing the time and labor intensity for mold changing.
In conclusion, with the passage of time, the progress and development of society, as well as the emergence of new materials and new technologies, the ZTRFM hydraulic bending machine molds are constantly being updated, changed and advanced. Its continuous improvement will enable us to obtain the products we need more easily and quickly, and will serve our society to a greater extent.
