Detailed Description
For a better understanding of the technical content of the present utility model, specific examples are set forth below, along with the accompanying drawings.
Referring to fig. 1-2, the present utility model proposes a deformation device for semi-steel cords, comprising a hollow shaft 10, three movable disks 20 and deformation needles 30 disposed on the movable disks 20, wherein the number of deformation needles on each movable disk is different according to the type of semi-steel cord produced, and optionally, 2-4 deformation needles 30 distributed in a circumferential array around the movable disk 20 are disposed on the surface of each movable disk 20.
For example 2*1, 2+2, one movable disk 20 has two deformed pins, three deformed pins if 3*1 type semisteel is produced, and four deformed pins if 4*1 type semisteel is produced.
Three movable disks 20 are provided to the surface of the hollow shaft 10, and a deforming needle 30 is connected to the surface of the movable disks 20; wherein, the surface of each movable disk 20 is provided with a plurality of deforming needles 30 distributed in a circumferential array around the axis of the movable disk 20, and three deforming needles 30 at the periphery of the three movable disks 20 form a deforming area 201 along the axis direction of the hollow shaft 10, and the semi-steel cord sequentially bypasses the three deforming needles 30 of the deforming area 201.
In a specific embodiment, taking a structure composed of two monofilaments as an example, referring to fig. 3, the first monofilament bypasses a group of deforming needles 30 above from the left side, and is S-shaped when being wound, and the second monofilament bypasses a group of deforming needles 30 below from the right side, and is S-shaped when being wound.
Further, the three movable disks 20 have a locking state and an active state, in which the three movable disks 20 can rotate within a certain range of included angles, and in which the angles between the three movable disks 20 are relatively fixed.
Thus, when it is necessary to change the deformation amount of the monofilament, the relative angle between the three movable disks 20 may be changed, and when the relative angle between the adjacent two movable disks 20 is larger, the deformation amount when the monofilament bypasses the deforming needle 30 is larger, and when the relative angle between the adjacent two movable disks 20 is smaller, the deformation amount when the monofilament bypasses the deforming needle 30 is smaller.
Optionally, the hollow shaft 10 is provided with a nut 11, and the nut 11 is configured to press the movable disks 20, and when the movable disks 20 are pressed, the three movable disks 20 are locked to each other.
Referring to fig. 3 to 4, when the nut 11 is rotated, there is a gap between the three movable disks 20, and at this time, the three movable disks 20 can be rotated relatively to control the relative angle therebetween, and when the nut 11 is tightened, the three movable disks 20 are pressed and the three movable disks 20 are fixed relatively.
Preferably, the three movable disks 20 are configured as a frustum, wherein the first movable disk 21, the second movable disk 22, and the third movable disk 23 are attached to each other, the major diameter of the first movable disk 21 is equal to the minor diameter of the second movable disk 22, and the major diameter of the second movable disk 22 is equal to the minor diameter of the third movable disk 23.
Thus, when the monofilament slides on the surfaces of the three movable disks 20, the friction with the surfaces of the movable disks 30 is small, and the winding is smooth.
In an alternative embodiment, the deformed needle 30 has a diameter of 4-8mm. In this way, most semisteel cord products can be accommodated.
Preferably, the deforming pin 30 comprises an alloy rod having a Rockwell hardness greater than 80, such that greater wear on the deforming pin 30 is avoided as the steel wire slides over the surface of the deforming pin 30.
In combination with the above embodiment, the deformation device of the utility model comprises three movable disks, the three movable disks are constructed into a frustum shape, the steel wire can slide on the surface of the movable disk, the movable disk is provided with a deformation needle, when the steel wire bypasses the deformation needle, a certain deformation amount is generated, and when the relative angle between the three movable disks is changed, the deformation amount of the steel wire can be controlled, so that different types of steel wires can be mutually twisted under a proper deformation amount, and the cord is more compact.
