Main purpose and scope
Stamping production is one of the basic methods of plastic processing, it is widely used in the aerospace, transportation machinery industry, and electronic appliances. As the sheet material to be processed, its stamping performance directly affects the quality and production efficiency of the finished product. Different stamping process, the relationship between the state of stress and deformation characteristics of plate deformation zone and force transmission area of the same, so the performance requirements for sheet metal stamping. In order to facilitate the study of the various stamping process plate performance requirements, based on the stress-strain state of the deformation zone of the stamping process classified as to stretch the main deformation and compression-based deformation.
The testing machine is used on the metal sheet and strip the tensile process test equipment. Test metal sheet and strip plastic deformation during the test performance can also be measured bulging sheet metal performance.
Testing the function of the anisotropy of the non-ferrous metal sheet.
Configure the appropriate mold can be carried out the corresponding metal sheet molded test. Ability to resist rupture detection for sheet metal stamping process. According basic stamping, can be:
Erichsen test, i.e. with certain specifications of the ball or spherical punch, when the specimen surrounding a certain clamping force is applied to pressure, the ball or spherical punch pressure is applied to the sample until the sample generated penetrating cracks until The punch is pressed into the depth (mm), namely the test sheet Erichsen value IE Erichsen value is used to determine the plastic deformation properties of the material.
Non-ferrous metal punch cup test, that certain specifications of cylindrical punch, some outside diameter of the wafer-shaped specimen clamping and clamping with a cup of mold between the the punch applied pressure, along the radial produce the extension and the curved plastic deformation once drawn into a cylindrical cup, the edge of the cup forming the lug-shaped projection, measured and calculated lug characteristic index lug rate e to determine the anisotropy of the material.
Main structure and working principle:
This machine adopts hydraulic clamping, stamping, punching speed can be adjusted pre-set, and can also be manually controlled, convenient the Cupping mold handling specimens fed sample is completed, press the Auto button clamping, stamping, sample cracks automatic parking, and easy to observe the cracks, peak memory function, ie the maximum punch pressure, deformation of highly automated memory. Deformation depth, punch pressure can be digital instrumentation, a touch screen or computer display, key operation, and can be pre-set deformation depth value. The machine can be configured to a simple digital display, touch screen display, computer control of a variety of display.
1, the test machine control principle
The test machine now digital display device to display the value of the clamping force, the momentum value, cupping value. The two sets of pressure sensors, a displacement sensor signal acquisition and display, user-friendly, comes with a set of manual keys can also be operated. The machine can also be configured according to user needs, computer operation and data acquisition. Model for GBS-60W microcomputer control automatic Cupping Testing Machine.
2 Product Features:
A Cupping testing machine with a new structural principle, servo motor load at a constant speed, constant rate control, the stamping process, controlled by a PC computer punching speed can be stepless speed advance the set. (Past the cylinder oil source afterburner can not achieve a constant rate control).
B, the clamping force by the hydraulic oil source independent load, the clamping force is adjustable, synchronous display of data, and can be independently calibrated.
C, the force measuring device has been changed in the past hydraulic pressure sensor for the spokes sensor, Erichsen value as measured encoder measurement, combined with spokes sensor (direct force measurement) greatly improved the accuracy and reliability of the projection values of the measuring cup of the testing machine.
Cupping fixture replacement convenient, easy sample handling, automatic button to complete the sample into the clamping test parameters can be input to change the stamping process automatic a key, no impact, can achieve closed-loop control, punch pressure values decreased judgment sample cracks automatic parking, easy to observe the trial process, more accurate judgments appear the crack instant cupping value. Test data computer display, and peak memory function, ie, the maximum punch pressure, cupping value statements, test results, storage, batch, curve drawing, deformation of a high degree of automatic memory, one end of the trial can be automatically restored to be tested status.
