Description
Technical Field
The utility model belongs to the field of optical cable preparation facilities, and particularly relates to an optical cable manufacturing die.
Background
The central reinforcing core of the layer-twisted optical cable is an important component of the layer-twisted optical cable and is arranged at the central position of the layer-twisted optical cable, and the central reinforcing core is used for supporting the sleeve-arranging unit and improving the tensile strength of the optical cable. Sleeve units are uniformly distributed on the periphery of the central reinforcing core. The central reinforcing core needs to pass through the central hole in the ointment mould of the yarn binding machine, and especially if there is ointment on the central reinforcing core, the end edges of the central hole of the ointment mould can scrape off the superfluous ointment on the central reinforcing core.
In the production process, after the central reinforcing core on one wire coil is used, the central reinforcing core on the production line needs to be connected with the central reinforcing core on the other wire coil, and a joint formed at the connection part needs to pass through a central hole on the ointment mould of the stranding table.
The connection modes of the central reinforcing core are mainly three according to different materials,
1) And (3) continuing side by side: mainly used for non-metal center reinforced core connection
2) Bending and continuing: the bending connection is the most robust way. But the joint area is relatively large in size.
3) Welding and butt joint: the joint part can reach the outline dimension close to the central reinforcing core through polishing, and an operator is required to have certain operation skills. The splicing operation is time-consuming.
The present production process has strict size requirements on the size of the central hole of the ointment mould, for example: 1.0mm of steel wire material, and the size of the central hole of the ointment mould is 1.2mm. The joint sizes of the side-by-side connection and the bending connection of the three connection modes are obviously enlarged relative to the diameter of the central reinforcing core, and the joint cannot pass through the central hole of the ointment mould, and only the electric welding connection mode is adopted. If the central reinforcing core made of non-metal materials is bent or formed in a side-by-side connection mode, the joint cannot pass through the central hole of the ointment mould, and then the central reinforcing core newly connected into the production line passes through the central hole of the ointment mould and then is connected with the central reinforcing core on the production line, so that the joint is sometimes required to be removed after cutting off the long length of the original central reinforcing core passing through the ointment mould on the production line, the waste of materials is caused, and the production cost is increased.

It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model. In addition, the technical features of the embodiments of the present utility model described below may be combined with each other as long as they do not collide with each other.
Referring to fig. 1 and 2, a die for manufacturing an optical cable comprises a die holder 1 and two groups of movable module assemblies, wherein:
the die holder 1 is of a hollow structure and is provided with a relatively large inner cavity, and the die holder 1 is of a frame structure as a whole; the two groups of movable module components are symmetrically arranged on the die holder 1.
For each set of the movable module assembly, it includes a movable module 3, a bolt 4 and a locking pin 5, the movable module 3 is located in the die holder 1 and slidably mounted on the die holder 1 so as to slide left and right. The die holder 1 may have various structures to slide the movable module 3, and the die holder 1 preferably has two horizontal slides disposed up and down oppositely, so that the movable module 3 slides left and right, and the two slides clamp the movable module 3 therebetween and serve as a guide for sliding the movable module 3. The movable module 3 is provided with a bolt receiving hole extending in the left-right direction and a pin hole extending in the front-rear direction. The bolt accommodating hole and the pin hole are preferably blind holes, the bolt accommodating hole and the pin hole are communicated with each other, the bolt 4 comprises a bolt head, a thread part and a bolt tail which are integrally formed, the bolt head can be a hexagon head, and the bolt head is arranged outside the die holder 1; if the bolt adopts an inner hexagon bolt, the bolt head is cylindrical and can be positioned in the die holder 1. The aperture of the bolt accommodating hole is larger than the diameter of the part of the bolt 4 extending into the bolt accommodating hole, the part of the bolt 4 extending into the bolt accommodating hole can freely move axially in the bolt accommodating hole, and the bolt accommodating hole does not influence the screwing of the bolt 4. The screw thread portion is located between the bolt head and the bolt tail, the screw thread portion is connected to the die holder 1, the bolt tail is provided with an annular groove 41 (which is equivalent to machining an annular groove 41 on the basis of the structure of the existing bolt 4) and extends into the bolt accommodating hole, the locking pin 5 is clamped into the pin hole and extends into the annular groove 41 at the tail, after the locking pin 5 is pinned into the pin hole, one end of the locking pin 5 is located in the annular groove 41 and is always located in the annular groove 41 no matter when the bolt 4 is unscrewed or screwed, the end of the locking pin 5 located in the annular groove 41 does not limit the rotation of the bolt 4, therefore, when the bolt 4 is screwed, the groove wall of the annular groove 41 of the bolt 4 can drive the locking pin 5 to move left and right together, the movement of the locking pin 5 can drive the movable module 3 to move left and right together, and the distance between the two movable modules 3 can be adjusted by screwing the bolt 4.
Each movable module 3 is provided with a notch groove at a side close to the other movable module 3, and the notch grooves extend in the front-rear direction.
The two notch grooves together form a through-hole 8 when the two movable modules 3 are brought together, so that the central reinforcing core of the twisted-pair cable passes through the cable production mould from this through-hole 8. If ointment is present on the central reinforcing core, the end edges of the through holes 8 will scrape off the excess ointment. The two said moving modules 3 are in sealing contact when they are close to each other, so as to prevent the leakage of the ointment on the central reinforcing core passing through the through hole 8. When a relatively large joint is formed by adopting a side-by-side joint or bending joint mode, the bolt 4 can be screwed, the space between the two notch grooves is enlarged, the joint can pass through the optical cable manufacturing die, then the bolt 4 is reversely screwed to enable the two movable modules 3 to be attached, and the shape of the through hole 8 and the ointment scraping function are recovered.
If the diameter of the central reinforcing core on the production line changes, the size of the through hole 8 also changes in a matched manner. When the utility model is suitable for the central reinforced core with changed diameter, only the locking pin 5 on the movable module 3 is required to be pulled out, then the movable module 3 is separated from the bolt 4, a new movable module 3 is replaced on the die holder 1, then the locking pin 5 is pinned on the movable module 3, and the locking pin 5 stretches into the annular groove 41.
Further, the present utility model further includes a positioning pin 2, the positioning pin 2 being mounted on the die holder 1 and extending in the front-rear direction.
Each movable module 3 is provided with a positioning groove at one side close to the positioning pin 2, so that the positioning groove contacts with the positioning pin 2 to enable the movable module 3 to stay at a set position. Because the central reinforcing core on the production line linearly advances, the position of the central reinforcing core occupied in space is fixed, therefore, the position of the through hole 8 relative to the die holder 1 is also fixed, the positioning pin 2 can limit the displacement amount of the moving modules 3 when approaching each other, each moving module 3 can stay at the same position when approaching each other, and the position of the through hole 8 relative to the central reinforcing core is also fixed. If the positioning pin 2 is not provided, the position of the through hole 8 is easy to change, so that the central reinforcing core is not aligned with the through hole 8, which may result in that the central reinforcing core is not coaxial with the through hole 8, the thickness of the ointment on the central reinforcing core is uneven, and the central reinforcing core and the movable module 3 may interfere and cannot pass through the optical cable manufacturing mold.
Further, the two positioning pins 2 are arranged up and down, and the central lines of the two positioning pins 2 and the central line of the through hole 8 formed by the two notch grooves are all on a vertical plane, so that the positioning of the movable module 3 and the forming and positioning of the through hole 8 can be facilitated.
Further, each group of movable module components respectively further comprises a guide rod 7, the guide rods 7 are fixedly installed on the die holder 1 and extend along the left-right direction, the movable modules 3 are movably installed on the guide rods 7 in a penetrating mode, and the guide rods 7 can guide movement of the movable modules 3, so that the movable modules 3 can move more smoothly.
Further, each group of movable module components respectively further comprises a compression spring 6 with a central line extending along the left-right direction, and the compression springs 6 are positioned between the die holder 1 and the movable modules 3 to apply elastic force on the movable modules 3, so that the two movable modules 3 are tightly attached together, and gaps for flowing ointment are prevented from being generated between the two movable modules 3 due to looseness. The compression spring 6 always exerts an elastic force on the movable module 3, whether the bolt 4 is screwed or unscrewed.
As another preferable scheme, each group of movable module assemblies further comprises a spring assembly, the spring assemblies comprise a guide rod 7 and a compression spring 6, the guide rod 7 is fixedly installed on the die holder 1 and extends along the left-right direction, the movable module 3 is movably installed on the guide rod 7 in a penetrating manner, the compression spring 6 is located between the die holder 1 and the movable module 3 and is installed on the guide rod 7 in a penetrating manner so as to apply elastic force on the movable module 3, and therefore the two movable modules 3 are tightly attached together, and the guide rod 7 can guide movement of the movable module 3 and is an installation basis of the compression spring 6, so that bending deformation of the compression spring 6 is effectively prevented. The spring assemblies preferably have a plurality of groups, so that the movable module 3 can be stressed more uniformly.
Further, the movable module 3 is made of metal or nylon. The movable module 3 made of metal material has long service life, and the movable module 3 made of nylon material has good sealing performance.
The utility model realizes the opening and closing by the two movable modules 3, designs a mold capable of opening and closing under the condition of ensuring that the existing installation and connection mode and basic size are not changed, realizes the adjustment of the space size between two notch grooves, facilitates the passing of joints in various forms, and meets the technological requirements and production demands.
