Description
Technical field
The present invention relates to a kind of cable capable of shielding digital signals in railways production equipment, specifically for the production of the shield machine of cable capable of shielding digital signals in railways.
Background technology
The inner shield operation is one of operation important in the cable capable of shielding digital signals in railways production process, be divided into the distortion of copper strips embossing, the vertical bag of film, the vertical bag of copper strips distortion, several stages of sizing moulding, because copper strips thickness only has 0.1mm, directly vertical bag can't guarantee even structure, rounding, shielding conductor group bending property is poor, must adopt the mode of pressure rolling diamond shaped pit, increases the used thickness of copper strips, with the mechanical performance behind the vertical bag of raising copper strips, and the copper strips behind the embossing has only improved mechanical performance.How to guarantee that the vertical of the uniform and stable distortion of copper strips wraps on the cable core, become the key point of this process quality, take different embossing and vertical bag mode of texturing, its screening mass is all had considerable influence, be in particular in the following aspects:
1. copper strips embossing
Copper strips embossing is laterally to be processed with the zigzag groove that tooth depth is 0.5mm in the pressure rolling roller surface, adjust its embossing thickness by the gap of adjusting between the diaxon, embossing thickness is less than normal, mechanical performance just can not satisfy instructions for use, and embossing thickness is bigger than normal, can cause the deformation drag of vertical bag large, easy broken belt, when copper strips is in uneven thickness, copper strips is directly broken, can't normally produce.
The vertical bag of shielding copper strips
Because copper strips hardening, thickening behind the embossing, with the vertical bag of common vertical Bao Changmo mouth die deformation, can't guarantee to shield the stable of vertical bag quality, vertical Bao Changmo mouth mould is to form with the thick corrosion resistant plate artificial deformation of 0.8mm, machining accuracy is low, and changeover portion, deformation section, outlet profiled section die size very easily change in the process that copper strips is advanced, after adjusting in process of production, sometimes use soon just because die size changes can't be continued to produce, show as broken belt, deformation drag large etc.
Vertical bag film
Vertical bag film is the vertical vertical bag separator that is wrapped between quad and the shielding copper strips, can play and avoid copper strips to hinder line, raising line insulation against ground performance, guarantee the lower stable effect of machine rounding of shielding.Guarantee stablely behind the vertical bag of film not expand, need the vertical bag of film and the vertical bag of copper strips are finished simultaneously, namely adopt simultaneously two long mould mouths in different size to finish, the vertical bag of film is complete to carry out immediately that copper strips is vertical to be wrapped.Smooth or film defectiveness, mould have when unusual when the cable core traveling, easily cause film vertical bag sideslip or are squeezed in the vertical copper-clad band lap-joint of shielding, have affected the vertical bag of shielding copper strips quality, can not guarantee the steady quality of lower machine product electrical property simultaneously.
Product quality
Adopt common embossing mode and the vertical bag of long mould mouth shielding, because product, die structure size are very unstable, cause the inadequate rounding of outward appearance, and gauffer is often arranged, electricity function index is also stable not, can not guarantee finished product digital signal cable electric property and mechanical and physical performance quality requirement.
For above problem, adopt above-mentioned traditional vertical packet mode and general corrective measure such as the quality that improves the raw material copper strips, promote worker's operative skill etc. and all can not tackle the problem at its root, can not guarantee the inner shield quality.
Summary of the invention
The shortcoming that exists in order to overcome above-mentioned vertical job contract skill, the object of the present invention is to provide a kind of shield machine for the production of cable capable of shielding digital signals in railways, it is simple to operate, lower machine constant product quality, can guarantee the physical dimension uniformity, the outward appearance rounding improves the cable capable of shielding digital signals in railways quality.
The technical solution adopted for the present invention to solve the technical problems is: for the production of the shield machine of cable capable of shielding digital signals in railways, it is characterized in that, comprise copper strips embossing machine, vertical bag proboscis mould and the vertical chartered plane of copper strips, described copper strips embossing machine comprises bearing and two pressure bundle rollers, press the bundle roller vertically to establish in opposite directions for two, be fixed on the bearing by back shaft, press the bundle roller to be provided with the embossing projection for one, another is pressed and pricks embossing groove that roller is provided with and the embossing projection is corresponding; The vertical chartered plane of described copper strips comprises the vertical bag of the copper strips welding bell of from left to right order installation, vertical pattern and the plug die of being bundled into.
A described knobbling rolls surface distributed is 1.5mm apart, dark 1mm, and the rhombus length of side is the embossing projection of 0.7mm approximately, and the embossing projection is arranged evenly at the knobbling rolls surface uniform, and another presses bundle roller surface distributed to have and the protruding corresponding embossing groove of embossing.
The vertical bag of described copper strips welding bell comprises supporting seat, be fixed with welding bell between the supporting seat, be provided with middle wire-passing tube along the welding bell axial direction, an end of middle wire-passing tube is on one of them supporting seat, and another supporting seat is provided with the through hole coaxial with middle wire-passing tube.
Vertical be bundled into pattern and comprise main mould and auxiliary mould, described main mould comprises the longitudinal covering model housing, is provided with a conical eccentric hole along longitudinal covering model housing axial direction, is provided with a pressing mold groove above perpendicular to the conical eccentric hole, and pressing mold groove two side is provided with the bolt fixing hole; Described auxiliary mould is positioned at the pressing mold groove, is respectively equipped with copper strips in the bottom surface of auxiliary mould and overlaps outer indent, internal layer copper strips crimping modification section and internal layer copper strips crimping typing section, and copper strips overlaps outer indent and is higher than internal layer copper strips crimping deformation section.
