Specific embodiments

[0026] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the following further details the present utility model in conjunction with embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0027] Embodiment 1:

[0028] Referring to Figures 1 to 3 , the present utility model provides a quantifiable adjustable needle - type deformer, including an adjustable base 1. An adjusting hole 13 is provided on the adjustable base 1, and a bracket 12 is arranged in the adjusting hole 13, and the position of the bracket 12 in the adjusting hole 13 is adjustable.

[0029] A wire dividing plate 2 is arranged on the bracket 12. A plurality of wire through holes 3 are equiangularly distributed on the wire dividing plate 2, and a cemented carbide die core is arranged in each wire through hole 3. Preferably, 6 or 5 wire through holes 3 are provided.

[0030] A deforming device is arranged on one side of the wire dividing plate 2. The deforming device includes a plurality of frustum - shaped mounting seats with gradually decreasing diameters. The plurality of frustum - shaped mounting seats and the wire dividing plate 2 are fixedly connected by bolts 9 and fixed nuts 11. A threading hole 10 is arranged on the central axis of the bolt 9, and a cemented carbide die core is also arranged in the threading hole 10.

[0031] A plurality of needle-shaped deformation rods 7 are equiangularly arranged on the side surface of each frustum-shaped mounting seat, and the number of needle-shaped deformation rods 7 on each frustum-shaped mounting seat is the same as the number of wire through-holes 3 on the wire dividing disc 2. The needle-shaped deformation rods 7 on the frustum-shaped mounting seat closest to the wire dividing disc 2 coincide with the center lines of the wire through-holes 3 on the wire dividing disc 2. The needle-shaped deformation rods 7 on adjacent frustum-shaped mounting seats are staggered, so that the steel wire 19 passing through each needle-shaped deformation rod 7 undergoes uniform deformation.

[0032] A scale 8 is provided on each frustum-shaped mounting seat, and a damping pad 14 is provided between adjacent frustum-shaped mounting seats. In actual setting, the scale 8 is set in units of 0.5 mm. The setting of the scale 8 facilitates the quantification of the deformation amount and makes the adjustment amount more accurate. According to the required deformation size of the steel wire 19, the position of the needle-shaped deformation rod 7 is adjusted with reference to the scale 8 on the corresponding frustum-shaped mounting seat, so that the positions of the needle-shaped deformation rods 7 on adjacent frustum-shaped mounting seats have a relative displacement, and the needle-shaped deformation rod 7 can be adjusted quantitatively.

[0033] See Figure 5 , one end of the needle-shaped deformation rod 7 is located inside the corresponding frustum-shaped mounting seat and the other end is connected with a limiting device. A plurality of needle-shaped deformation rod mounting holes are provided on each frustum-shaped mounting seat, bearings are provided in the needle-shaped deformation rod mounting holes, and the bearings are rotatably connected with the inserted needle-shaped deformation rods 7.

[0034] The limiting device is detachably inserted on the needle-shaped deformation rod 7. Specifically, the limiting device includes a limiting cap 201, the limiting cap 201 is connected with a limiting rod 203, an insertion hole can be provided at the end of the needle-shaped deformation rod 7, and the limiting rod 203 is inserted into the insertion hole. The limiting cap 201 is of a cross-shaped structure, and a limiting edge 202 that is bent downward is provided on the outer periphery of the limiting cap 201 to prevent the steel wire 19 from sliding and disengaging from the needle-shaped deformation rod 7.

[0035] In actual application, the deformation device includes three frustum-shaped mounting seats with gradually decreasing diameters, namely the third needle-shaped deformation rod mounting seat 6, the second needle-shaped deformation rod mounting seat 5, and the first needle-shaped deformation rod mounting seat 4. The third needle-shaped deformation rod mounting seat 6 is arranged close to the wire dividing disc 2, and damping pads 14 are provided between the third needle-shaped deformation rod mounting seat 6 and the second needle-shaped deformation rod mounting seat 5, and between the second needle-shaped deformation rod mounting seat 5 and the first needle-shaped deformation rod mounting seat 4. When 6 wire through-holes 3 are provided on the wire dividing disc 2, 6 needle-shaped deformation rods 7 are provided on the third needle-shaped deformation rod mounting seat 6, the second needle-shaped deformation rod mounting seat 5, and the first needle-shaped deformation rod mounting seat 4 respectively. The steel wires 19 passing through the 6 wire through-holes 3 pass through the corresponding needle-shaped deformation rods 7 to undergo deformation, and then converge and twist with the steel wires 19 passing through the wire threading holes 10 to form a 6 + 1 cord structure. See Figure 4When 5 wire through-holes 3 are provided on the wire distributing disc 2, 5 pin-type deformation rod mounting seats 6, 5 second pin-type deformation rod mounting seats 5 and 5 first pin-type deformation rod mounting seats 4 are all provided with 5 pin-type deformation rods 7. The steel wires 19 passing through the 5 wire through-holes 3 respectively pass through the corresponding pin-type deformation rods 7 and are deformed, and then converge and twist with the steel wires 19 passing through the wire threading holes 10 to form a 5 + 1 cord structure. The deformed steel wires 19 are outer steel wires, and the steel wires 19 passing through the wire threading holes 10 are central steel wires. When the two are twisted, since the outer steel wires passing through the pin-type deformation rods 7 have been deformed, 1 central steel wire with a specified wave crest and wavelength will not be squeezed and deformed by 6 or 5 outer steel wires, making the rope-forming product not easy to come loose at the head, and further improving the quality of the rope-forming product.

[0036] Before the steel wires 19 enter the deformation device, they can be combed first to make the steel wires 19 entering the wire distributing disc 2 smoother. Therefore, a wire combing disc 18 can be provided on the other side of the support 12 (i.e., the side opposite to the deformation device). A number of wire combing disc holes and a central hole corresponding to the wire threading hole 10 are provided on the wire combing disc 18. The wire distributing disc 2 with different numbers of wire threading holes 10 can be adapted.

[0037] In order to further improve the uniformity of the steel wires 19 during the converging and twisting process and avoid some steel wires 19 being in a loose state before converging and twisting, a plurality of tension adjusting rollers 17 are provided before the steel wires 19 pass through the wire distributing disc 2. The plurality of tension adjusting rollers 17 are arranged between the wire distributing disc 2 and the wire combing disc 18. The plurality of tension adjusting rollers 17 correspond to the wire through-holes 3 on the wire distributing disc 2 one by one. The tension adjusting rollers 17 are connected to the side of the wire distributing disc 2 far from the deformation device through micro-cylinders 16. Micro-cylinders 16 are arranged on the outer edge of each wire through-hole 3 on the wire distributing disc 2, and the height of the tension adjusting rollers 17 is adjusted through the micro-cylinders 16, thereby realizing the adjustment of the steel wires 19. A tension adjusting frame can also be provided on the support 12, and the same number and corresponding positions of the wire through-holes 3 on the wire distributing disc 2 are provided on the tension adjusting frame. The way of adjusting the tension of the steel wires 19 by the cooperation of the tension adjusting rollers 17 and the micro-cylinders 16 can also be replaced by the cooperation of the tension adjusting rollers 17, the servo motor and the adjusting frame.

[0038] Through the quantifiable adjustable pin-type deformer of the present utility model, the structure is simple, the adjustment is convenient, the deformation amount is adjustable, and the deformation amount can be adjusted more stably and accurately during the running process of the steel wires, ensuring that the wave crest of the outer steel wires against the central steel wires is not squeezed and deformed, the steel wires are well and evenly formed into ropes, and are not easy to come loose at the head, greatly improving the quality of the rope-forming product.

[0039] Certainly, the present utility model can also have many other embodiments. Without departing from the spirit and essence of the present utility model, those skilled in the art can make various corresponding changes and deformations according to the present utility model, but these corresponding changes and deformations should all fall within the protection scope of the appended claims of the present utility model.
