in the figure: the special die comprises 1 polypropylene rope hemp-covering equipment, 2 polypropylene rope die sleeves, 3 polypropylene rope die cores, 4 self-locking grooves, 5 self-locking blocks, 6 polypropylene rope die sleeve reserved die core positions (center holes of the polypropylene rope die sleeves), 7 polypropylene rope die sleeve HALF blocks, 8 polypropylene rope die core HALF blocks, 9 limiting screws, 10 limiting grooves, 11 polypropylene rope hemp-covering equipment center through holes and 12 original polypropylene rope dies.

Detailed Description

A novel polypropylene rope wrapping die comprises a polypropylene rope die sleeve 2 and a polypropylene rope die core 3, wherein the polypropylene rope die sleeve is arranged at a central through hole 11 of polypropylene rope hemp wrapping equipment 1, and the polypropylene rope die core is arranged in a central hole 6 of the polypropylene rope die sleeve; the polypropylene rope die sleeve and the polypropylene rope die core are both HALF block structures.

The two HALF blocks 7 of the polypropylene rope die sleeve are locked and self-locked into a whole through the self-locking grooves 4 and the self-locking blocks 5, and the two HALF blocks 8 of the polypropylene rope die core are locked and self-locked into a whole through the self-locking grooves 4 and the self-locking blocks 5. The self-locking block is a dovetail convex block, the self-locking groove is a dovetail groove, and the dovetail convex block and the dovetail groove are of a gradually-changing structure with a large front part and a small rear part.

A plurality of limiting grooves 10 are uniformly distributed on the outer circumference of the polypropylene rope die sleeve, a plurality of limiting screws 9 are uniformly distributed on the end face of the central through hole of the polypropylene rope hemp-covering device, and the limiting screws and the limiting grooves are in one-to-one clamping correspondence to position the polypropylene rope die sleeve.

Specifically, the method comprises the following steps:

1. the utility model discloses spacing groove: 6 limit grooves are uniformly formed in the outer circumference of the die sleeve and are clamped and positioned with a fixing screw (a limit screw) on the end face of a central through hole of the polypropylene rope gunny wrapping equipment, so that the die is prevented from rotating along with the twisting direction when gunny wrapping is carried out.

2. The utility model discloses change original polypropylene rope mould into mold core, die sleeve split type, place in the die sleeve center when the mold core uses, as shown in figure 1.

Because the central through hole of the polypropylene rope gunny wrapping device may need an overlarge buckle when pulling the head, the size of the die is large, more nylon bars are needed, no die is needed for the central through hole at the moment, and the die is loaded after the buckle passes through the through hole, so the die needs to be designed into a half structure of a die sleeve and a die core. The die sleeve is made of PA66 material, and has stronger mechanical property compared with PA6, and various mold cores of adaptation increase life.

3. The utility model discloses the die sleeve half piece uses from the locked groove form, realizes the auto-lock, leaves the gap after avoiding installing, can play fixed effect and accurate installation mold core. The self-locking groove has higher processing and matching difficulty, so that a gradual change type with a big front and a small back is adopted, the installation is simple, the disassembly is convenient, and the self-locking groove is naturally locked when the half block of the mould is closed to the outside and level.

4. The utility model discloses the mold core position is reserved at the die sleeve center, and the mold core uses the material to be PA6, workable, and the price is low, chooses for use different internal diameters according to the optical cable is different, because of the components of a whole that can function independently form that adopts die sleeve, mold core, only need change different mold cores during different cable types and different equipment, and nylon bar volume reduces greatly, practices thrift the cost.

5. The mold core structure is similar to a mold sleeve, the half block is locked by using a self-locking groove with a gradually-changing front size and a small back size, self-locking is realized, a gap is avoided after installation, and the problems of broken polypropylene ropes and wire jumpers of the original mold are solved. The self-locking groove has higher processing and matching difficulty, so that a gradual change type with a big front and a small back is adopted, the installation is simple, the disassembly is convenient, and the self-locking groove is naturally locked when the half block of the mould is closed to the outside and level.

The utility model discloses when using, load general polypropylene rope die sleeve earlier, load one of them HALF piece earlier, drop into the locking of auto-lock groove with second HALF HALF piece, select the polypropylene rope mold core of adaptation according to different optical cable types again, operating method loads with the die sleeve. The outer diameter of the polypropylene rope die sleeve is in clearance fit according to the specific conditions of equipment, and the processing and loading are convenient. The polypropylene rope die sleeve and the die core are matched with each other by clearance fit, and a tolerance zone is H6/g6, so that the loading and dismounting processes are not laborious, and the polypropylene rope die core and the die sleeve cannot rotate freely. When the die is machined, the self-locking groove uses a special customized milling cutter, and other machining references a common wrapping die.
