Description

The mould structure that a kind of twisted wire presses

Technical field

The utility model relates to the mould structure that a kind of twisted wire presses, particularly a kind of mould structure pressing effective twisted wire and pressing.

Background technology

Low tension wire core is wound around to press by many copper (aluminium) single line to form, and in the process producing electric wire core, except wishing copper (aluminium) single line longer service life, requires in use not easily to disperse simultaneously. But in prior art, copper (aluminium) single line forming cable does not very easily make cable conductor external diameter little not well because pressing effect, also round whole not, cause inconvenience is installed, visual appearance is poor, not good owing to compressing effect, causes the diameter of core bigger, thus cause the sheath material consumption wrapping up core relatively big, cause cost to remain high. That overcome the above problems it is crucial that make wireline can be good at being pressed on together. But the equipment not solved the problem well now.

Practical novel content

The purpose of this utility model is, it is provided that the mould structure that a kind of twisted wire presses. This mould can make many copper (aluminium) single line etc. can be good at being pressed on together, and presses effective. Thus make cable conductor external diameter less, more round whole, and then reduce the outside diameter of cable so that installing better, also improve visual appearance simultaneously, reduce cost of manufacture, good in economic efficiency.

The technical solution of the utility model: the mould structure that a kind of twisted wire presses, comprises placement unit, and placement unit side is with to tighten unit hinged, and another side of placement unit and locking unit are hinged; Described placement unit comprises placed cavity, and placed cavity is placed cover plate, is provided with mould in placed cavity, and mould is provided with wears hand-hole; Described unit of tightening comprises and tightens plate, tightens plate and is provided with and tightens post, tightens plate and be connected with locking slot; Described locking unit comprises locking bolt, and locking bolt coordinates with locking slot, and locking bolt is connected with screwed cap, and the outside surface of placed cavity coordinates with the internal surface of cover plate.

In the mould structure that aforesaid twisted wire presses, on the upside of described placed cavity, also it is provided with block.

In the mould structure that aforesaid twisted wire presses, described placed cavity comprises at least 2 sub-placed cavities.

Compared with prior art, many steel wires feedings are worn in hand-hole by transmission mechanism by the utility model, by tightening post, make to tighten post and cover plate is produced squeezing action, cover plate is fixed, then copper (aluminium) single line making to be placed in placed cavity is neat, compact arrangement, avoids copper (aluminium) single line and is wound around chaotic, makes the life of core. Baffle plate is set, cover plate can be avoided upwards to slide, inconsistent phenomenon occurs, makes the arrangement that core is more neat, compact. At least 2 sub-placed cavities are set, like this can according to the size of copper (aluminium) single line, that selects different size wears hand-hole, regulates mould to coordinate with corresponding sub-placed cavity, makes applied widely. The following is the part test that applicant carries out, to prove the beneficial effects of the utility model:

Applicant is for low tension wire BLVV1*16, and this electric wire core aluminium single line external diameter is 7/1.70mm, and after stranded, (non-press) stranded external diameter is 5.1mm. When core through external diameter be 4.8mm press mould after, the external diameter of electric wire core is 4.8mm, and core external diameter reduces 0.3mm. Contrast the non-product and press rear product processes parameter of pressing, the results are shown in Table 1 and table 2.

Table 1BLVV1*16 production technique table (non-press)

Table 2BLVV1*16 production technique table (pressing)

As can be seen from the above table, core presses rear external diameter and reduces 0.3mm, but due to cross section be still 16mm², so its electrical property can not change, the quality of product can not be reduced, to this, this product is delivered to the type approval test that electric wire inspection center of country has made full performance by applicant, and all indexs comply with the national standard requirements.

Owing to the external diameter of electric wire is reduced to 8.6mm by 8.9mm, the insulation of electric wire and the consumption of sheath just reduce to some extent. Through calculating when electric wire (non-press) external diameter is 8.9mm, the polyvinyl chloride with sheath consumption that insulate is 58.5 grams/meter; When electric wire (pressing) external diameter is 8.6mm, insulation and the polyvinyl chloride of sheath consumption are 56.0 grams/meter. Every meter is reduced the consumption of 2.5 grams of polyvinyl chloride.

Applicant gets the bid 18000 kilometers at south electric network this year, reduces the consumption calculations of 2.5 grams of polyvinyl chloride by every meter, and the accumulative consumption that can reduce by 45 tons of polyvinyl chloride, by current market value 8000 yuan/ton, for company saves 360,000 yuan.
