Description
Technical field
The invention belongs to flexible pipe production equipment and method, relate to the hard core depoling method of a kind of rubber hose and mandrel string thereof.
Background technology
Skeleton strengthens the interior punch die used in flexible pipe production process, usually plastic material is had, quality of rubber materials and steel matter, use steel matter as the production technology of interior punch die hard core method flexible pipe production technology, this technique uses the steel wire rope of hoist engine to be pulled out from body by hard core at present, hard core could be realized at production process hoist engine and body apart from the length that at least will equal hard core entirely to deviate from, steel wire rope elasticity is large once fracture can cause major accident, when therefore producing, depoling goes to isolate, produce space hold very large, and skeleton rope folding and unfolding production efficiency is back and forth very low.
Summary of the invention
The present invention, in order to make up the deficiencies in the prior art, provides the hard core depoling method of a kind of rubber hose esy to use, safe and reliable and mandrel string thereof, makes rubber hose can depoling continuously, enhances productivity, stops potential safety hazard simultaneously.
The present invention is achieved through the following technical solutions:
The hard core mandrel string of rubber hose of the present invention, its special character is: comprise hauling machine and depoling instrument, the base of hauling machine is provided with the conduction chain of two levels, depoling instrument comprises baffle plate, depoling die sleeve and drawing bar, baffle plate is arranged on base near conduction chain porch, depoling die sleeve is arranged on baffle plate, and depoling die sleeve is with for inserting hard core and blocking the centre bore of flexible pipe, and the end that can be clamped in the drawing bar between conduction chain connects hard core top.
Preferred version is, described drawing bar connects hard core by connecting rod, the external diameter of drawing bar is identical with hard core external diameter, and drawing bar end is drilled with hard core front end the internal thread hole that specification is identical, direction is contrary, and two of connecting rod machined the external screw thread just connecting drawing bar and the hard core of steel.
With the stair coaxial circular hole in convex on described baffle plate, center, hole is consistent with the clamping center of two conduction chains; Depoling die sleeve profile is in " convex " shape corresponding with baffle plate convex-shaped hole.
Described depoling die sleeve is several, and the center hole size of each depoling die sleeve is different to adapt to the different hard core choice for use of thickness.
The hard core depoling method of rubber hose of the present invention, its special character is: first carry out contour parallel milling to the hose end before depoling, hard core is made to expose flexible pipe one section, the suitable depoling die sleeve of centre bore is selected to be installed on the baffle plate of mandrel string conduction chain porch, the hard core exposed is passed depoling die sleeve centre bore, drawing bar is connected with hard core by connecting rod, then starts mandrel string and carry out depoling; Mandrel string relies on the rubber press on conduction chain and conduction chain to be clamped by the drawing bar of depoling, conduction chain running drives drawing bar to run forward the hard core of drive and goes ahead, the flexible pipe be coated on hard core keeps original position by baffle plate and the restriction of depoling die sleeve, achieves the extraction of hard core.
The invention has the beneficial effects as follows, esy to use, safe and reliable, make rubber hose can depoling continuously, enhance productivity, stop potential safety hazard simultaneously, produce space hold less.

Detailed description of the invention
Accompanying drawing is a kind of specific embodiment of the present invention.
The hard core mandrel string of rubber hose of the present invention, comprise hauling machine and depoling instrument, the base of hauling machine is provided with the conduction chain of two levels, depoling instrument comprises baffle plate, depoling die sleeve and drawing bar, baffle plate is arranged on base near conduction chain porch, depoling die sleeve is arranged on baffle plate, and depoling die sleeve is with for inserting hard core and blocking the centre bore of flexible pipe, and the end that can be clamped in the drawing bar between conduction chain connects hard core top.Described depoling die sleeve is several, and the center hole size of each depoling die sleeve is different to adapt to the different hard core choice for use of thickness.
Mandrel string realizes in the normal traction machine transformation with horizontally tracting chain, the base of hauling machine entrance is fixed the baffle plate of thickness an about 100mm, baffle plate is respectively the stair coaxial circular hole of 150mm, 100mm with diameter in " convex " shape, center, hole is consistent with the clamping center of two conduction chains.
Depoling die sleeve and " convex " shape hole corresponding " convex " shape steel plate on baffle plate, external diameter is respectively 99mm, 149mm, and there is the centre bore of 0.5-0.7mm larger than steel hard core external diameter in mold center.
Described drawing bar connects hard core by connecting rod.The external diameter of drawing bar is identical with steel hard core external diameter, and drawing bar end is drilled with steel hard core front end the internal thread hole that specification is identical, direction is contrary.Two of connecting rod machined the external screw thread just connecting drawing bar and the hard core of steel.
Depoling method is, first contour parallel milling is carried out to the sebific duct hose end before depoling, the hard core of steel is made to expose sebific duct 10-15cm, the suitable depoling die sleeve of centre bore is selected to be installed on the baffle plate (being positioned at mandrel string afterbody) of mandrel string conduction chain porch, the hard core exposed is passed depoling die sleeve centre bore, drawing bar is connected by the hard plug of connecting rod and steel, then starts mandrel string and carry out depoling; Mandrel string relies on the traction of the rubber press on forward part conduction chain and conduction chain to be clamped by the drawing bar of depoling, conduction chain clamping drawing bar runs forward and drives the hard core of steel to go ahead, the sebific duct be coated on the hard core of steel keeps original position by baffle plate and the restriction of depoling die sleeve, achieves the extraction of hard steel core.After the steel core extraction of first sebific duct, repeat the continuous depoling that above operation realizes sebific duct.
