Its powerful search functions as mechanical system design and technology provides an important auxiliary tool, greatly reducing their calculations. CAXA2000 unique system query functions including point coordinates, distance between two points and angles, element attributes and perimeter, area and center of gravity inquiries, moment of inertia, query system status and so on. These systems query capabilities specific to the mold design hdpe couplers mould and manufacturing, CAXA2000 technicians ready to die, they have become an indispensable assistant with CAXA pressure center in solving Die Die, the pressure force of the punch, said the point of center of pressure for the mold. Die pressure center should coincide with the axis of the press slide, the slider from the eccentric load impact. Otherwise, it will accelerate the wear of the slider and the guide portion of the mold, which affects the quality of stamping parts, reduce die life. The method for solving the current mold pressure center is generally used analytical method or graphical method. When analytical method to calculate the workload, error-prone, and plotted graphically on the level designers demanding, but it is difficult to ensure accuracy. Stamping parts in the calculation of the center of pressure, according to the punching force calculation formula: F = LtS where F blanking force ridgeline length L t workpiece thickness S punching shear strength of the workpiece material effect on the punching force evenly the role of the center line, so that the center of gravity of the workpiece blanking force contours. If solving the analytical method, the first look-up table to get the coordinates of the center of gravity of each segment is calculated by solving the above center coordinates calculated tedious, error-prone, in fact, we can directly apply CAXA focus the inquiry, obtain plastic coupler fittings mould the coordinates of the center of gravity values. The steps are as follows: a pro-rata basis to draw the workpiece shape (marked decimals and decimals inquiry, drawing decimals are set to 4); marked by setting the number of (set display decimal places); according to system configuration settings (to set the query decimal places. ). b. for workpiece contour equidistance line (to improve accuracy, the distance can be set equidistant 0.01) and move the coordinate origin O points. Press Setup, select the user coordinate - the origin, intelligent capture point O points, left the pickup, press Enter. c. original contour line layer to hide, with the focus of the inquiry found CAXA focus of two equidistant lines surround the area into strips. Focus query method:
. a with the mouse in the "Query> drop-down menu, select <center> Options b in the drawing area immediately below the screen menus and operation prompt, select the ring point (Note: Immediately menu <increase ring> is the pickup closed region and other regions to accumulate, "Reducing the ring> refers to the enclosed area is subtracted from other regions). c. Right-click the query results show the coordinates of the center of gravity. After testing, equidistant from the center of gravity coordinates 0.1, the query was obtained as Q (51.715,27.466), equidistant from 0.01 when the query to get the coordinates of the center of gravity for the Q (51.624,27.123), apparently taken equidistant from 0.01 to get The coordinates of the plastic mould center of gravity to fully meet the requirements of precision mold design. Rough calculation of the size of the drawing parts drawing in non-thinning, excluding material thickness changes. Usually by the surface area of the product plus repair parts of the surface area of the side margin. In other words, with the front and rear deformation principle for calculating the surface area equal parts drawing wool size. To determine pre-drawing sheet size, we must first calculate the gross area of the workpiece.
The mold is used to shape the article tool that constitute various parts of different parts of the mold by a different composition. It is mainly formed by changing the physical state of the material to achieve the shape of the article processing. In blanking, forming stamping, forging, cold forging, extrusion, compression molding or injection molding powder metallurgy processing repression
