Abstract
An extruding out head for preparing flat cable is composed of main body with side plate and press cover of distributor, neck unit, flat material distributor connected to outlet of neck unit, mould core connected with said distributor, rectangular mould sleeve, and the jacket of said mould sleeve. Its advantages are high productivity and easy installation and detaching.
Description
Technical field
The present invention relates to the structure of a kind of novel extruder head of flat cable, belong to cable manufacturing process equipment technology field.
Background technology
Existing flat cable extrusion die is the flat molds of developing on typical circular or square head, mainly be made of die sleeve, core rod, tripper, machine neck etc., divide two kinds: a kind of is the manual adjustment core shift, and another is to exempt from the tuningout core; Its common ground: the machine neck is a flaring exit, and is relative with the circular import of tripper; Tripper is circular configuration in the head, the profile of this circular its core rod of sub-material principle and die sleeve also is circular configuration, but extrude as adapting to flat cable, its core rod mouth and die sleeve mouth will excessively be flat pattern all, therefore the actual fabrication difficulty is big, and gap, the every place of core rod and die sleeve when plastics enter mould, not exclusively big or small, unbalanced when extruding to both sides sub-material pressure, owing to the big reason of local pressure causes line group spacing skewness easily, attractive in appearance and the stress balance of flat cable is extruded in influence, and stressed disequilibrium can directly influence the service life of cable; And because circular sub-material is extruded the limitation that cable widths is subjected to the head tripper, factor such as φ 90 extruding machines of considering extrusion pressure can only partition glassware internal orifice dimension be the head of φ 60mm, add the upper mold core inner wall thickness and generally can only extrude flat cable about width 40mm; Can only extrude the cable of 70mm left and right sides width on φ 150 extruding machines, along with increasing the extruding machine specification, the flat cable width to increase, thereby further increase equipment investment cost and extrude power consumption, and because circular tripper sub-material length adds upper mold core length, whole head threading distance is longer, the threading difficulty is scalded insulated wire cores easily, again because of long plastics of threading time easy incipient scorch in the head machine barrel, it is rough and scrap that the beginning cable has been extruded 20 meters left and right sides outward appearances, so it is bigger to extrude waste, increased the manufacturing cost of cable.
Summary of the invention
Purpose of the present invention is exactly the deficiency that exists at existing flat cable extrusion die, provides a kind of threading convenient, and extrusion pressure is even, exempt to regulate core shift, extruding cable does not have waste, and line group cross-sectional distribution gap is even, the extruding nose of flat cable that the cable external form is more attractive in appearance.
The object of the present invention is achieved like this, extruding nose of flat cable comprises tripper, core rod, die sleeve that installation is set in body, machine neck and the body, it is characterized in that being provided with the die sleeve overcoat, die sleeve is set in the body relative with tripper outward, and die sleeve is arranged in the die sleeve overcoat; The machine neck is the semicircle stratified feeding structure of five equilibrium, machine neck one end adpting flange, and the other end is connected with body; Tripper is that the flat structure is corresponding with the semicircle stratified feeding structure of machine neck five equilibrium; Core rod, die sleeve also are the flat rectangle structure, core rod one end is enclosed within on the tripper, other end core rod mouth is concentric with the die sleeve mouth, one end of body be provided be connected with tripper and with the fixing tripper Side plate of body, the other end of body be provided with push down die sleeve and die sleeve overcoat and with the fixing gland of body.
The separation structures such as semicircle of described machine neck, be from connect machine barrel and filter between head two flanges begin nappe gradually transition be that two prismatic rectangles export.Tripper is the flat structure, and tripper import and the outlet of machine neck should be corresponding fully stratified feeding structure up and down, and tripper exports to the structure that core rod is divided into rectangular five equilibrium discharging all around again.But the outlet not necessarily equates around the characteristic of frictional resistance during according to plastic flow, tripper.
The present invention is scientific and reasonable for structure, compact, manufacture, easy installation and removal. machine neck one end adpting flange, the other end is connected with body, the machine neck adopts separation structures such as semicircle, be that to begin nappe with filter between head two flanges excessively be that two prismatic rectangles export gradually from connecting machine barrel, be connected to the plastics of tripper with body, be stratified feeding up and down, sub-material is even. and tripper is the flat structure, stratified feeding structure up and down with the relative connection of machine neck outlet, the tripper discharging is divided into rectangular five equilibrium discharging all around again to core rod, guarantee the harmony of the sub-material pressure that flat cable is extruded, extrude even that flat cable group spacing distributes, improve cable service life, increase the cable good looking appearance. core rod, the die sleeve branch is placed in tripper and the die sleeve overcoat, is the flat rectangle structure, core rod, die sleeve and tripper, the concentricity of die sleeve overcoat and body should be able to satisfy the regulation requirement, exempts from the tuningout core when guaranteeing to produce.
Die sleeve can carry out flat cable grouping fluting according to the purposes of flat cable, every group of leg-of-mutton necking tool of equidistant protrusion when corresponding die sleeve is made.For making things convenient for tearing open of core rod, die sleeve, die sleeve overcoat, gland and tripper imperial, make the imperial device of tearing open that adopts screw mandrel, utilize the lever rotation to eject principle.The machining accuracy of its each assembly and provision for disengagement should meet the regulation requirement of design, and material should be to forge breaks the 45# steel, after low temperature carburization, guarantees that head and various parts are hard, wear-resisting, corrosion resistant, heat-resistant deforming.Tripper and core rod post lump together, and tripper adds core rod length and has only 21cm, and tripper is short and the back opening is big, and threading is convenient, and the threading time is short, extrude the flat cable surface and do not have burnt material, do not have waste, and smooth in appearance is smooth.
Extruding nose of flat cable is compared with common head, extruding width at same extruding machine wants big 2-2.5 doubly, cable group pressure is even, extrudes because of exempting to regulate core shift, and threading is short at one's leisure, extrude cable and do not have waste, line group cross-sectional distribution gap is even, and the cable external form is more attractive in appearance, long service life, compare service life with the flat cable that common head is extruded, will long 5-10 by the fatigue test proof that cable is crooked back and forth.
Extruding nose of flat cable is suitable for various extruding machines and rubber extruding machine, and extruded material such as soft polyvinyl chloride, the fine polymer of fourth, polyvinyl chloride elastomer, butadiene-styrene rubber, neoprene and silicon rubber all can be extruded.Mix heater and can be used as the thermoplastic extruder head, extrude soft polyvinyl chloride, the fine polymer of fourth, polyvinyl chloride elastomer etc.; Mix water tank, the logical Steam Heating that goes up can be used as rubber extruder head, extrudes butadiene-styrene rubber, neoprene etc., and the logical cooling water of going up is extruded silicon rubber as the silicon rubber extruder head.Applicability is strong, of many uses, supporting scientific and reasonable with extruding machine or rubber extruding machine, can effectively avoid the wasting of resources, has improved production efficiency widely and has increased economic benefit, and it is very wide to promote the use of prospect.
