Description
Technical field
The utility model relates to the auxiliary equipment that plastic pipe manufactures, and especially heavy caliber moulds pipe cooling shaping apparatus for correcting.
Background technology
The forming method of general plastic tube extrusion has external diameter to shape and internal diameter typing method two kinds.In external diameter typing method, one uses external diameter shaping cover, can pass into cooling water in the middle of this cover, hangs and be associated on head, heat insulation with head polytetrafluoroethylene (PTFE) insulating collar.Fill compressed air in plastic pipe pipe to make outer surface of plastic pipe be attached to shaping cover inner surface to cool fixed dimension rapidly, constant in order to safeguard interior pressure, the plastic pipe of pipe with small pipe diameter can encase tube head by direct film, the plastic pipe inside dress rubber stopper of Large Diameter Pipeline, rubber stopper pull bar is fixed on plug.Compressed-air actuated pressure size depends on the viscosity of plastic pipe diameter, wall thickness and material, generally at 2 ~ 5kPa.Internal diameter typing method: be generally used for right-angle type head.Extended by core and 80 ~ 300mm, inner logical cooling water, by core extending shaft external diameter determination plastic pipe internal diameter.Plastic pipe can ensure internal diameter size tolerance, extending shaft
designtapered, its tapering is 0.6% ~ 1.0%.
General system of selection sizing need determine according to factors such as plastic pipe size, appearance requirement.
Heavy caliber moulds that tubular elastic is large, mechanical strength fluctuation is large, as can not be accurately formalized in refrigerating work procedure, easily occur flexural deformation, can make the deformation defects such as surface generation is uneven, bending, distortion, wave, these are out of shape the workmanship directly affecting part and product.Therefore must correct.
Utility model content
The purpose of this utility model is to provide a kind of heavy caliber and moulds pipe cooling shaping apparatus for correcting, prevents pipe deformations, ensures the out of roundness of tubing.
The purpose of this utility model will be realized by following technical measures: comprise driven roller, discharge outlet, water inlet, casing, correct roller and checkout gear; Bottom of shell installs driven roller, casing is installed discharge outlet and water inlet, casing inner wall is installed correct roller and checkout gear.
Especially, in the middle part of driven roller or two ends are hinged on bottom of shell.
Especially, in casing, cross the same sectional uniform of axle and arrange at least two correct rollers.
Advantage of the present utility model and effect: before tubing refrigerating work procedure completes, carry out multiple roll heat straightening with mechanical technology, can not only obtain accurately consistent caliber size and high pipe end out of roundness, also rectifiable pipe end buckling deformation.
Accompanying drawing explanation
Fig. 1 is the utility model embodiment 1 structural representation.
Reference numeral comprises: heavy caliber moulds pipe 1, driven roller 2, discharge outlet 3, water inlet 4, casing 5, correct roller 6, checkout gear 7.
Detailed description of the invention
The utility model principle is, is divided into gagging and heat straightening by the temperature of workpiece when correcting.Gagging is the rectification that workpiece carries out at normal temperatures, and the gagging undertaken by means such as knocking extensions will cause the flow harden of material, and the plasticity storage of consumable material, so be only applicable to the good steel of plasticity.In the utility model, belong to the comparatively large or fragile material of distortion to large molecule synthesis plastic material and generally can not use gagging, common iron also will avoid use under severe cold low temperature.The process of correcting is exactly that steel are by the process of elastic deformation to plastic deformation.Therefore, material will inevitably also exist certain elastic deformation in plastic deformation.The rectification carried out at normal temperatures is corrected cold-working.So in the utility model, before tubing refrigerating work procedure completes, multiple roll heat straightening must be carried out with mechanical technology.
The utility model comprises: driven roller 2, discharge outlet 3, water inlet 4, casing 5, correct roller 6 and checkout gear 7.
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Embodiment 1: as shown in Figure 1, installs driven roller 2 bottom casing 5, casing 5 is installed discharge outlet 3 and water inlet 4, casing 5 inwall is installed correct roller 6 and checkout gear 7.
In aforementioned, heavy caliber moulds pipe 1 diameter more than 200mm.
In aforementioned, in the middle part of driven roller 2 or two ends are hinged on bottom casing 5.Driven roller 2 can rotate, and former rear drive heavy caliber is moulded pipe 1 and moved forward and backward, or, roll while movement.
In aforementioned, discharge outlet 3 is connected with pipeline with water inlet 4, carries out spraying or cold bath circulating cooling in casing 5 inside.
In aforementioned, in casing 5, cross the same sectional uniform of axle arrange at least two correct rollers 6.
In aforementioned, in casing 5, tank length is 2 ~ 3m, divides 2 ~ 4 sections, makes heavy caliber mould pipe 1 leaving water temperature and reach about 30 DEG C.
During utility model works, heavy caliber is moulded after pipe 1 tubing leaves shaping cover and is not cooled completely, need enter bosh continue cooling for preventing distortion.Pile cold water in tank in casing 5, by plastic pipe submergence, tank rear end water inlet in casing 5, front end water outlet, to mould pipe 1 direction of motion contrary with heavy caliber, and plastic pipe is cooled gradually.Casing 5 inner cooling water groove can be designed to fountain tank, prevents heavy caliber from moulding pipe 1 and is out of shape by buoyancy in water.Mould pipe 1 at heavy caliber should be out of shape by first distortion correction, rear rectification flexural deformation, record heavy caliber according to checkout gear 7 and mould pipe 1 deformation parameter, mould self material of pipe 1 and dimensions in conjunction with heavy caliber simultaneously, adjustment cooling water temperature flow velocity, driven roller 2 operating angle and rotating speed, and the clamping parameter of correct roller 6, make heavy caliber mould pipe 1 by during casing 5 while moving forward high-speed rotation except turning round, cavetto, repair straight, till rectification.
