Description

Technical Field

[0001] This utility model relates to the field of steel cord manufacturing technology, and in particular to a rope forming frame used in BOF2 vehicle platform. Background Technology

[0002] Steel cord is made of high-quality high-carbon steel with a brass-plated surface, consisting of fine-gauge steel wire strands or ropes for special purposes. It is mainly used as a reinforcing material for passenger car tires, light truck tires, heavy-duty truck tires, construction machinery tires, aircraft tires, and other rubber products.

[0003] The BOF2 machine is a commonly used piece of equipment in steel cord production. Its internal compartment contains two inner feed spools, but it is only suitable for single-wire feed. When each feed spool uses double or multiple wires, multiple (≥2) wires may pass through the same guide wheel simultaneously, easily causing tangling and wire breakage during production. Furthermore, because the original rope-forming frame lacks a forced rope-forming binding structure, the rope quality of the product fluctuates, resulting in defects such as looseness or uneven twisting. Utility Model Content

[0004] The purpose of this invention is to provide a rope-forming frame for the BOF2 machine. Two guide rollers are installed on the third and fourth vertical shafts respectively. When producing seven-wire products, the three wires are separated at the guide rollers after passing through the swing arm, ensuring that only one single wire passes through each guide roller, thus effectively preventing wire tangling. Furthermore, a forced rope-forming binding structure is added behind the splitter, ensuring the tightness of the rope and the quality of the formed rope, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A rope-forming frame for use on a BOF2 trolley includes a base, on which a first vertical shaft and a second vertical shaft are connected. A guide wheel A and a guide wheel B are respectively connected to the top of the first and second vertical shafts.

A forced rope-forming binding mechanism is connected to the end of the base away from the third and fourth vertical shafts. The forced rope-forming binding mechanism includes a die head with die holes.

[0006] A further improvement of this utility model is that the base includes a base plate with mounting holes, a vertical plate connected to the bottom of the base plate, and a triangular reinforcing plate connected between the vertical plate and the base plate; the base plate is in the shape of an isosceles trapezoid, and a rectangular groove is provided in the center of the base plate for fixing the wire divider and the forced rope binding mechanism.

[0007] A further improvement of this utility model is that the first vertical axis and the second vertical axis are symmetrically arranged on both sides of the groove, the wire guide wheel A and the wire guide wheel B are flush, the top ends of the first vertical axis and the second vertical axis are connected to the support, and the front ends of the two supports are respectively connected to two wire guide nozzles.

[0008] A further improvement of this utility model is that a support block is connected in the groove, the bottom end of the splitter disc is slidably fitted to the support block and is provided with an elongated adjustment hole, the adjustment screw passes through the adjustment hole and is threaded to the support block to lock the splitter disc and the support block; the splitter hole is set at the top of the splitter disc, there are six splitter holes in total, arranged in a circular array with the center position of the splitter disc.

[0009] A further improvement of this utility model is that the third vertical axis and the fourth vertical axis are symmetrically arranged on both sides of the groove, and the three guide wheels C are flush with the three guide wheels D respectively.

[0010] A further improvement of this utility model is that the forced rope binding mechanism also includes a mold base, which is connected to the front end of the support plate. The mold head is snapped onto the mold base, and a slide is connected to the top of the mold base. An elastic pressure rod is connected to the slide, and the elastic pressure rod can press against the top of the mold head.

[0012] A further improvement of this utility model is that two limiting pins are connected to the outer wall of the slide rod at the top of the slide block, and two limiting grooves are provided at the top of the slide block, with the limiting pins engaged in the limiting grooves.

[0013] The beneficial effects of this utility model are: The rope forming frame of this utility model, applied to the BOF2 machine, has two wire guide wheels installed on the third and fourth vertical shafts respectively.

The groove 105 is 20mm wide, 126.96mm long, and 2.5mm deep.

[0024] The first vertical shaft 2 and the second vertical shaft 3 are symmetrically arranged on both sides of the groove 105. The wire guide wheel A4 and the wire guide wheel B5 are flush. The top ends of the first vertical shaft 2 and the second vertical shaft 3 are connected to the support 12, and the front ends of the two supports 12 are respectively connected to two wire guide nozzles 13.

[0025] A support block 14 is connected in the groove 105. The bottom end of the splitter plate 6 is slidably fitted to the support block 14 and is provided with an elongated adjustment hole 602. The adjustment screw passes through the adjustment hole 602 and is threaded to the support block 14 to lock the splitter plate 6 and the support block 14. The splitter hole 601 is set at the top of the splitter plate 6. There are six splitter holes 601 in total, which are arranged in a circular array around the center of the splitter plate 6.

[0026] The third vertical axis 7 and the fourth vertical axis 8 are symmetrically arranged on both sides of the groove 105, and the three guide wheels C9 are flush with the three guide wheels D10 respectively.

[0027] The forced rope binding mechanism 11 also includes a mold base 1103, which is connected to the front end of the support plate. The mold head 1101 is snapped onto the mold base 1103. A slide 1104 is connected to the top of the mold base 1103. An elastic pressure rod is connected to the slide 1104. The elastic pressure rod can press against the top of the mold head 1101. The diameter of the mold hole 1102 is 0.85mm. The mold head 1101 is made of alloy material.

[0028] The elastic pressure bar includes a slide bar 1105, with a pressure block 1106 connected to the bottom end of the slide bar 1105. The outer diameter of the pressure block 1106 is larger than the outer diameter of the slide bar 1105. A handle 1109 is connected to the top end of the slide bar 1105. A stepped hole 1107 is provided at the center of the slide block 1104. The slide bar 1105 is slidably fitted into the small diameter section of the stepped hole 1107, and the pressure block 1106 is slidably fitted into the large diameter section of the stepped hole 1107.

The top end of the spring 1108 is engaged with the stepped surface of the stepped hole 1107, and the bottom end of the spring 1108 abuts against the top end of the pressure block 1106.

[0029] Two limiting pins 1110 are connected to the outer wall of the slide rod 1105 at the top of the slide block 1104. Two limiting grooves 1111 are provided at the top of the slide block 1104, and the limiting pins 1110 are engaged in the limiting grooves 1111.

[0030] The specific working principle of this utility model is as follows: In the production of steel cord with 7 monofilaments, the steel wire is led out from the feed shaft, passes through the guide rollers on the first vertical shaft 2 and the second vertical shaft 3, and then reaches the swing rod. Next, at the positions of the third vertical shaft 7 and the fourth vertical shaft 8, the steel wire is divided into three monofilaments, each of which passes through a guide roller independently. After exiting from the guide rollers, the steel wire is guided by the splitter 6 to the forced rope-forming binding structure during rope formation. Then, it passes through structural components such as the small boat, and finally completes the winding operation on the take-up reel. This modification to the rope-forming frame structure effectively avoids the cross-entanglement and resulting wire breakage problems that may occur when multiple monofilaments pass through the same guide roller simultaneously. The newly added forced rope-forming binding structure ensures that the rope quality meets the requirements.

[0031] During operation, the pressure block 1106 presses the die head 1101 under the tension of the spring 1108. When the die head 1101 needs to be replaced, the operator pulls the handle 1109 upward, the slide bar 1105 moves upward, the limit pin 1110 disengages from the limit groove 1111, and the slide bar 1105 is rotated. The two limit pins 1110 are locked in the top of the slide block 1104. At this time, the pressure block 1106 leaves the die head 1101. The operator pulls the die head 1101 out of the die base 1103 and replaces it with a new die head 1101. The operator pulls the handle 1109 again and rotates the slide bar 1105. The limit pins 1110 are locked in the limit groove 1111, and the pressure block 1106 presses the new die head 1101 again under the tension of the spring 1108.
