Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 2, straightener workpiece press-bending amount control device comprises that pressure block 7, lower pressure block 8, feeding piece 9(feeding piece 9 are a skewback), spring 10, baffle plate 11 and pressure measurement unit.Upper pressure block 7 is pressed on lower pressure block 8 and with the upper surface slide of lower pressure block 8 and coordinates, feeding piece 9 is positioned at a side of lower pressure block 8 and is slidably matched with lower pressure block 8, baffle plate 11 is positioned at the opposite side of lower pressure block 8, one end of spring 10 is pressed on baffle plate 11, and the other end of spring 10 is pressed on lower pressure block 8.
The lower surface of the upper surface of upper pressure block 7 and lower pressure block 8 is the inclined plane cooperatively interacting, and the upper surface of upper pressure block 7 is high near the height of a side of baffle plate 11 near the aspect ratio of a side of feeding piece 9.Feeding piece 9, lower pressure block 8 and spring 10 are in same level position, and lower pressure block 8 and upper pressure block 7 are in same vertical position.In the time using this straightener workpiece press-bending amount control device, change lower pressure block 8 horizontal cross positions by the adjusting to feeding piece 9 horizontal lengthwise positions, and then make pressure block 7 produce relative displacement at vertical direction, the horizontal cross displacement of pressure block 8 under this process medi-spring 10 changes.
While using this straightener workpiece press-bending amount control device, straightener workpiece press-bending amount control device need be arranged on workpiece straightener, as shown in Figure 3, workpiece straightener comprises servo-actuated thimble 1, pressure head 2, drives thimble 3, compression struts 4, working slider 5, bearing plate 6 and pressure measurement unit.Servo-actuated thimble 1, compression struts 4 and driving thimble 3 are arranged on working slider 5 and can move with working slider 5 (can move left and right), and pressure head 2 working slider 5 relative to bearing plate 6 is static.Working slider 5 is arranged on bearing plate 6 and with bearing plate 6 and slidably coordinates.On working slider 5 and be positioned at pressure head 2 under a through hole is set, on bearing plate 6 and be positioned at through hole under cavity is set, straightener workpiece press-bending amount control device is arranged in cavity, lower pressure block 8 is positioned at the bottom of cavity, and upper pressure block 7 fixes in the horizontal direction with bearing plate 6 and in the vertical direction is slidably matched.Feeding piece 9 oblique cuttings are between a side of lower pressure block 8 and a sidewall of cavity, baffle plate 11 is near another sidewall of cavity, compression struts 4 under pressure head 2 passes through hole and is slidably matched with working slider 5 in the vertical directions, and the bottom of the compression struts 4 under pressure head 2 is pressed on pressure block 7.
The height that is the compression struts 4 under pressure head 2 with the maximum difference of existing workpiece straightener after this straightener workpiece press-bending amount control device is arranged on workpiece straightener can regulate, by the press-bending amount of the fine adjustment Control Shaft rod workpieces 12 to this compression struts 4.
