Abstract
A limiting mechanism of a nylon zipper forming machine includes an upper die and a lower die that are mutually matched, as well as two forming screws side by side arranged on the matching surface of the upper die and the lower die, wherein two bearings tangent to the two forming screws through threads respectively are arranged on the front side wall and the rear side wall of the lower die; and the bearings on the front side wall and the rear side wall are positioned on the two sides of the forming screws respectively. The bearings tangent to the two forming screws and arranged on the front side wall and the rear side wall of the lower die are used for limiting the forming screws, the forming screws avoid the upper die and the lower die, and the bearings and the forming screws perform opposite and relative motion to reduce the friction coefficient of the bearings to the greatest extent, thereby guaranteeing the stable center distance of the two forming screws, prolonging the serving life of the dies and the forming screws, guaranteeing the product burr, specification fluctuation, thread forms and the like, and improving the operation rate of equipment.
Description
Technical field
The utility model relates to art of zipper fabrication, more specifically refers to the position-limit mechanism of nylon zipper forming machine.
Background technology
In the zipper industry field, nylon zipper forming machine is requisite equipment during nylon zipper becomes to produce, the forming machine critical piece comprises the shaping screw of upper and lower mould and pair of parellel, a center line that is guided from lower to upper vertical lifting by center bar is arranged under the screw rod, nylon wire of lateral leadin, nylon wire constantly twines as the axle center take center line, and under the shaping screw rotation, makes nylon wire be subjected to thread to be squeezed into the cast sprocket in the spiral shell ditch.
The upper and lower mould of existing forming machine by the step groove snapping, directly cooperates transmission with shaping screw usually again.In process of production, because under high temperature and the high-speed drive, it is bad etc. that the wearing and tearing that mould and the mutual friction of shaping screw phase produce can cause product burr, specification fluctuation, tooth form to occur.In addition, shaping screw and die wear are serious, service life is low, and probably at 10-15 days, frequency of maintenance is high, Homes Using TV is low, causes inefficiency inferior.For this reason, we provide a kind of position-limit mechanism of nylon zipper forming machine.
Summary of the invention
The utility model provides a kind of position-limit mechanism of nylon zipper forming machine, cooperates shortcomings such as there being above-mentioned deficiency with between the mould that solves existing nylon zipper forming machine and the screw rod.
The utility model adopts following technical scheme:
The position-limit mechanism of nylon zipper forming machine, comprise upper and lower mould and two shaping screws of being located at side by side on the upper and lower mould mating surface of cooperatively interacting, be equipped with on the front and back sidewall of described bed die two respectively with described two bearings that the shaping screw screw thread is tangent, the bearing on the sidewall of front and back divides and occupy the shaping screw both sides.
The central axis of above-mentioned bearing and the central axis of shaping screw are on the same level.
Preferably, also be provided with on the sidewall of above-mentioned bed die one with the equal tangent bearing of described two shaping screw screw threads, also be provided with on the sidewall of described mold one with the equal tangent bearing of described two shaping screw screw threads.
Further, above-mentioned mold is provided with a strip bulge, and the strip bulge lower surface is provided with two the first half slots of arranging side by side along its length direction, and described bed die correspondence is provided with two the second half slots that cooperate with the first half slot.
Further, above-mentioned strip bulge width is provided with the first half-arc groove of crossing over two the first half slots, correspondence is provided with the second half-arc groove on the bed die, the first half-arc groove and the second half-arc groove form an annular groove, place a location steel loop in this annular groove, described two shaping screws are arranged in the steel loop of described location side by side.
By above-mentioned description to the utility model structure as can be known, be compared with existing technology, the utlity model has following advantage:
1, the position-limit mechanism of this structure is arranged at the tangent bearing of shaping screw by sidewall before and after bed die and limits shaping screw, shaping screw and upper and lower mould are avoided, bearing and shaping screw are done in opposite directions, relative motion, its coefficient of friction is down to minimum, thereby guarantee the stable of two moulding screw rod centre-to-centre spacing, improve the service life of mould and shaping screw, the aspects such as product burr, specification fluctuation, tooth form are protected, simultaneously the lifting means running rate.
2, the side in the vertical direction of upper and lower mould also is provided with two all bearings tangent with shaping screw, further limit the play of shaping screw in the vertical direction, make the rotation of two moulding screw rods more stable, further prolong shaping screw and mold use life-span.
3, this position-limit mechanism also is provided with a location steel loop, further limits two shaping screws mobile in the horizontal direction the time, can prevent that also two moulding screw rods from producing deformation etc. under hot environment.
4, this position-limit mechanism is simple in structure, practical, and is with low cost, improved the qualification rate of product, improved and seen per capita probability (about 20%), reduced maintenance of equipment rate (about 30%).
