The specific embodiment
Lift a preferred embodiment below, and combine accompanying drawing to come the clearer the present invention that intactly explains.
As shown in Figure 1; BOPET biaxial tension sheet material special fixture of the present invention comprises first lining 1, first bearing pin 2, second lining 3, U type spring 4, chuck 5, clamp 6, second bearing pin 7, the 3rd bearing pin 8, dog screw 9, clamping plate 10, plain washer 11, spring washer 12, hex bolts 13; First lining 1 and second lining 3 are loaded on the U type spring 4, and chuck 5 is loaded on the clamp 6 through the 3rd bearing pin 8; For preventing that the 3rd bearing pin 8 and clamp 6 break away from; Be designed with dog screw 9 and carry out axial location; Promptly the 3rd bearing pin 8 carries out axial location with clamp 6 through dog screw 9; The bottom side of U type spring 4 is fixing by second bearing pin 7, and the left side of U type spring 4 is first to be loaded on the clamp 6 through first bearing pin 2, and clamping plate 10 are fixed on the clamp 6 by hex bolts 13; For preventing the rotation of clamping plate 10 in clamping drawing process, plain washer 11 and spring washer 12 are housed on the hex bolts 13.As shown in Figure 2, be designed with axial tooth profile groove 14 on the clamping area of chuck 5, when making the BOPET sheet material clamp with biaxial tension non-slip with take off folder; Because sheet material is in warm-up mode when biaxial tension, this makes that chuck 5 was prone to throw off sheet material when the sheet material deliquescing made stretched sheet, in order to solve this difficult problem; As shown in Figure 3; Chuck 5 is provided with cam lock locking structure 15, and this makes no matter sheet material can both guarantee that when not being heated and being heated clamping is firmly non-slip and take off the folder phenomenon, thereby guarantees effective stretching of sheet material.
Chuck 5 provides elastic force that chuck 5 is unclamped by U type spring 4 when unclamping sheet material, after chuck 5 is unclamped, positions, and as shown in Figure 4, the top of clamp 6 is provided with setting element 16.
As shown in Figure 5, the contact-making surface of the end face of clamping plate 10 and chuck 5 is provided with prismatic serrated slot 17, is convenient to sheet material and clamps and stressedly when stretching evenly unlikelyly to take off folder with skidding, and guarantees the production of reliable and stable BOPET biaxial tension sheet material.Clamping plate 10 can be as required simultaneously; The thickness of stretched sheet is changed, thereby the sheet material precision is high, and accurate positioning clamps with stretched sheet stressed evenly.
The chuck and the clamping plate wearability height of BOPET biaxial tension sheet material special fixture of the present invention all adopt the wear-resisting ductile iron material, and intensity is high, and it is indeformable to be heated, dimensionally stable; And wearability is high, can reach very long service life, chuck, clamp, clamping plate locating shaft machining accuracy height; Precision can reach 0.01mm, the reliable clamping when guaranteeing clipping sheets, and clamping accuracy is high; U type spring adopts spring steel, after its moulding, has carried out heat treatment; Guarantee good springiness, the anti-antifatigue time is long, makes the folding chuck sensitive.Chuck and cleat design exclusive anti-skid structure, the sheet material when avoiding clamping two-way BOPET and stretching skids and takes off folder.
Though more than described the specific embodiment of the present invention, it will be understood by those of skill in the art that these only illustrate, under the prerequisite that does not deviate from principle of the present invention and essence, can make numerous variations or modification to these embodiments.Therefore, protection scope of the present invention is limited appended claims.
