Bending machine molds are mainly divided into upper and lower molds, of which the upper mold is the active mold and the lower mold is the passive mold.
Top Mode Category：
1.Sharp knife mold: the angle of the tip of the knife is mostly 30 degrees or 60 degrees, suitable for straight line bending.
2.Arc die: designed according to the diameter and arc length of the arc, suitable for arc bending.
3.Bending Die: Mainly used for “U” shaped workpieces or avoidance in multiple bending.
4.Forming dies: they can be one-piece or combined, suitable for bending of complex shapes. Combined dies have advantages in large-size and complex graphic dies.
Lower mold classification:
1.Single V-Die: Only one die slot, suitable for simple bending operations.
2.Double V-Die: With two die slots, it is suitable for bending operations that require higher precision.
3.Multi-V die: There are multiple die slots, suitable for bending of various thicknesses of sheet materials, especially suitable for large-size molds and complex graphic molds.
The main details of the bending machine molds are classified:
1.Categorized by material:Bending machine molds can be divided into metal molds, plastic molds, rubber molds and so on. Metal molds are usually used for processing metal parts, with high strength and durability. Plastic molds and rubber molds are mainly used for processing plastic and rubber parts, with good wear resistance and corrosion resistance.
2.Categorized by use:Bending machine molds can be divided into stamping molds, stretching molds, bending molds and so on. Stamping molds are mainly used for stamping and forming of metal plates, such as automobile body, parts and so on. Stretching molds are mainly used for metal stretching, such as cylindrical parts, box-shaped parts. Bending molds are used for bending metal plates, such as angles and channels.
3.Categorized by structure:Bending machine molds can be divided into single-station molds, double-station molds, multi-station molds and so on. Single-station molds complete the entire forming process in one operation. Double station molds and multi-station molds can complete different forming processes in multiple stations to improve productivity.
4.Categorized by accuracy:Bending machine molds can be divided into precision molds, ordinary molds and so on. Precision molds have high processing accuracy and finish, applicable to high-precision requirements of parts processing. Ordinary molds are suitable for general precision requirements of parts processing.
5.Categorized by shape:Bending machine molds can be divided into round molds, square molds, shaped molds and so on. Round molds and square molds are mainly used for bending and forming of metal plates. Shaped molds are used for the formation of complex shaped parts, such as car bodies, aircraft parts and so on. The above is the main classification of bending machine molds.
The importance of bending machine molds:
1.Molding processing sheet:Bending machine mold is a bending machine used to form the tools used to process the plate, through the bending machine pressure to change the physical state of the material, so that the blank becomes a specific shape and size of the parts, to meet the needs of product design and production.
2.Increased productivity:The use of molds makes the bending process of sheet material more standardized and automated, reducing the complexity and error of manual operation and greatly improving production efficiency. At the same time, the precision and durability of the mold ensures the stability of the production process and the consistency of product quality.
3.Realization of diversified processing:There is a wide range of bending machine molds, including molds with different angles, lengths, widths, thicknesses and grooves, as well as single and multifunctional molds. These molds can meet the bending needs of plates of different shapes, sizes and requirements, and achieve diversified processing.
4.Protect the bending machine:Reasonable use of the bending machine mold can protect the bending machine itself, to avoid excessive pressure or impact generated during the bending process on the bending machine damage.
5.Ensure operational safety:In the bending process, the correct use of the mold can protect the operator’s safety and prevent the sheet from buckling or sliding during the bending process, thus avoiding injury to the operator.
Precautions for using and maintaining bending machine molds:
1.Turn on the power and start the oil pump:Turn on the power of the bending machine, twist the key switch, press the oil pump start button, the bending machine oil pump begins to rotate.
2.Stroke adjustment:You need to test when you officially start bending work with the bending machine tooling to make sure that there is a plate thickness clearance when the upper die is lowered to the very bottom to prevent damage to the tooling and the machine.
3.Choose the right groove:Generally choose a notch that is 8 times the width of the plate thickness, for example, to bend a 4mm plate, you need to choose a notch of about 32.
4.Check the overlap and robustness of the mold:Frequently check the overlap of the upper and lower molds and the indication of the pressure gauge for compliance.
5.Operational safety:Sheet bending must be compacted to prevent the sheet from buckling and injuring the operator; adjusting the sheet pressure mold must be cut off after stopping the power supply.
6.Prohibit the use of sheet material that exceeds the performance range:It is prohibited to use sheet material that exceeds the performance of the bending machine to avoid damaging the machine.
7.Summarize:By taking these correct measures, you can effectively utilize and maintain the bending machine tooling to ensure its efficiency and safety in use.
