Description
Technical field
The present invention relates to a kind of crimping unit, be specifically related to folding brake and fold method that a kind of thickness is the 0.5-1.2mm plastic plate.
Background technology
The relative steel plate of ABS plastic thin plate adopting suitable process, satisfies under the condition of working strength at weight, cost, have than remarkable advantages in appearance, and replacing steel plate is just becoming the powerful measure of falling this section Zhi Tigao market competitiveness.For with the ABS plastic sheet applications on refrigerator as postnotum, the ABS plastic thin plate replaces steel plate also need carry out the flanging moulding.
At the folding brake that uses at present, the principle of flanging is as being: utilize the V font that is turned into of two horizontal turnover panels to finish the flanging action, at first ABS plastic thin plate location is placed on the horizontal turnover panel, at this moment heater by the below treat crease heat (crease is between two turnover panels) simultaneously the push type broach of crease top push down crease, 15-20 is after second in heating, the turnover panel upset forms the V font, with the sheet material flanging.
At above-mentioned folding brake, mainly contain several difficult points: the softening point that 1, is difficult to be heated to the ABS plastic thin plate during flanging at the relative steel plate forming of ABS plastic thin plate flanging moulding; 2, monolateral to ABS plastic thin plate heating, the lack of homogeneity that causes the ABS plastic thin plate to be heated causes the flanging after the moulding to be distorted; 3, the fillet at crease place is excessive behind the flanging, does not reach product requirement; 4, the rigidity of equipment is difficult to guarantee, equipment heat expansion distortion easily under heated condition simultaneously.
Summary of the invention
Main purpose of the present invention provides a kind of folding brake and fold method of plastic plate, and the present invention can make by the sheet material of moulding of flanging and reach corresponding softening point, and is heated evenly, and makes the flanging of moulding have the measured advantage of matter.
For reaching above-mentioned purpose, the present invention proposes a kind of fold method of plastic plate, and it adopts folding brake to carry out flanging by following steps:
Step 1, the upper slitter triangular in shape and the following tool rest of heating folding brake: upper slitter is heated to 120 ℃-160 ℃ by heating plate, and following tool rest is heated to 80 ℃-100 ℃ by heater, compressed air is transported to down after heater heating the groove face to lower knife groove heats in the lower knife groove triangular in shape of tool rest, all is incubated 15-25 minute after upper slitter and time tool rest are heated to design temperature;
For reaching above-mentioned purpose, the present invention proposes a kind of folding brake, the structure of this folding brake is: the bracing frame upper end is provided with down tool rest, the upper surface of this time tool rest is provided with the leg-of-mutton lower knife groove of downward tool rest medial recess, the angle of lower knife groove bottom is 80 °-85 °, the middle part of following tool rest is provided with the heater that is positioned at the lower knife groove below, following tool rest is provided with the pod apertures that a upper end is communicated with the lower knife groove bottom, the lower end of this pod apertures is communicated with heater, following tool rest upper surface is provided with the vertically left slider and the right slide block of displacement movement, left slider is connected a drive unit separately with right slide block, two ends of going up knife support are connected with right slide block with left slider respectively, last knife support is provided with leg-of-mutton upper slitter, and the angle of upper slitter bottom is less than the angle of lower knife groove bottom, and upper slitter is provided with heating plate.
Adopted such scheme, by upper slitter plastic plate is heated, plastic plate is added be subjected to corresponding softening point, by following tool rest to after being heated by the plastic plate of flanging, plastic plate is heated evenly, avoid being distorted after the flanging moulding, making the flanging of moulding by folding brake of the present invention and fold method is linear pattern, and the quality of flanging is improved significantly.The angle of lower knife groove bottom is 80 °-85 °, the limit and the angle between the plastic plate that fold by folding brake also are 80 °-85 °, provide wider space for the flanging cooling forming like this, make behind the flanging cooling and shaping and the angle between the plastic plate body reaches 90--92 °, cause flanging to meet the requirements.
Following tool rest upper surface is provided with the locating piece that the position can adjust, and this locating piece is positioned at the notch next door of lower knife groove.By locating piece plastic plate is carried out spacing because therefore the fixed distance of locating piece and notch, for four flangings of same plastic plate, can guarantee the width unanimity.
Upper slitter is provided with gap, owing to when flanging, fold opposite side earlier on plastic plate, in the process of folding, the crosspoint is arranged for remaining both sides with the both sides of rolling well, and the both sides that can avoid having rolled well by gap, therefore, can improve the quality and the outward appearance of flanging.
Bracing frame is provided with and supports the support light rail of tool rest down, and the cross section of this support light rail is " worker " font.By supporting light rail, can guarantee down the rigidity of tool rest, can prevent down that tool rest produces the heat expansion distortion simultaneously under heated condition.
Support frame as described above is provided with and detects the photoelectric detection switch of going up cutter position.By pass, Photoelectric Detection sky last cutter position is controlled, can be guaranteed the quality of flanging.
