Description

Technical Field

[0001] This invention relates to the field of cutting materials, and in particular to a seamless self-closing steel rope loop for cutting. Background Technology

[0002] Ring-shaped steel ropes are mainly used for cutting hard and brittle materials such as solar silicon wafers, semiconductors, sapphire, or stone; they can also be used as reinforcement materials for synchronous belts, transmission belts, etc.

[0003] The "ring-shaped beaded diamond rope for stone cutting" disclosed in Chinese Patent Publication No. CN208323832U includes a main line connected in a ring shape. The main line includes a central metal baseline, which is made of 7 to 13 metal wires twisted together. Multiple capillaries are uniformly fitted on the metal baseline. A diamond abrasive layer is provided on the outer surface of the capillaries by brazing. A chip-receiving groove is formed between two adjacent capillaries, and an injection-molded layer is provided on the surface of the chip-receiving groove.

[0004] Chinese Patent Publication No. CN109834606A discloses "A steel wire cutting rope and its preparation method", which includes: Step 1: drawing a relatively thick high-carbon steel wire, stainless steel wire or tungsten alloy steel wire to a diameter of 0.01-0.20 mm using equipment; Step 2: Option 1: electroplating copper on the surface of the drawn steel wire and then twisting them together into a strand (2-19 strands); Option 2: first twisting the drawn steel wire together into a strand (2-19 strands), and then electroplating copper on the surface of the strand after twisting; Step 3: electroplating diamond powder on the surface of the copper-plated strand; Step 4: cutting the strand to complete, with a diameter of 0.02-1.00 mm.

[0005] Existing loop steel ropes have a weakness: low joint strength. They are usually connected by knotting, welding, or using other tubular materials. The diameter of the joint changes greatly, or the material and structure change, making them inconvenient to use or significantly reducing their strength. The strength of the welded joint is only about 40% of the strength of the steel rope, which can easily cause the entire steel rope to fail. Summary of the Invention

[0006] The purpose of this invention is to provide a seamless, self-sealing steel rope loop for cutting, which ensures that the strength of the entire loop of steel rope is consistent without any weak points, and also improves the product's service life and other performance characteristics.

[0007] To achieve the above objectives, the technical solution of the present invention is as follows:

[0008] A seamless, self-sealing steel rope loop for cutting, characterized in that the steel rope loop is a seamless, ring-shaped closed structure, and the cross-sectional structure of the steel rope loop consists of inner and outer layers of steel rope. The inner layer of steel rope has more than one turn, and the outer layer of steel rope is wrapped around the inner layer of steel rope. Furthermore, along the circumference of the steel rope loop, the outer layer of steel rope has more than one turn, covering the starting point of the outer layer of steel rope and the head of the inner layer of steel rope. The tail end of the outer layer of steel rope is inserted into the loop or fixed by soldering. The steel rope is made of multiple strands of steel wire with a diameter of 0.04 to 1 mm twisted together.

[0009] Preferably, the inner steel rope has two or more turns and is arranged in parallel, or is wound with a large twist pitch of more than 200.

[0010] Preferably, the steel rope structure is Nx1, M+N, MxN; where M and N = 1, 2, 3, 4, 5, 6, 7.

[0011] Preferably, the surface of the rope loop is coated with diamond powder or sand.

[0012] Preferably, the steel wire is carbon steel or stainless steel with a carbon content of 0.7 to 1.2 wt%.

[0013] Preferably, the steel wire has a copper or zinc plating.

[0014] The device for manufacturing a seamless self-sealing steel rope loop for cutting, as described in this invention, comprises: a wire feeding reel, a traction reel, a guide reel, and a loop forming mechanism arranged sequentially; wherein, the loop forming mechanism comprises: a driven reel, which is a semi-circular ring structure; at least three driving reels, evenly arranged along the circumferential direction of the outer edge of the driven reel; at least three magnetic guide reels, evenly arranged along the inner and outer edges of the driven reel; and at least three rope loop auxiliary guide reels, wherein at least two rope loop auxiliary guide reels are arranged parallel to each other on both sides of the center of the driven reel, and one rope loop auxiliary guide reel is arranged at the center below the outer side of the driving reel in the circumferential direction, and the rope loop auxiliary guide reels are arranged in a triangular pattern.

[0015] Furthermore, it also includes a fuse, which is located in front of or behind the guide wheel.

[0016] The method for manufacturing a seamless self-sealing steel rope loop for cutting according to the present invention includes the following steps:

[0017] 1) Laying out the lines

[0018] The steel rope is laid out via a wire-laying reel, pulled by a traction wheel, and guided through a guide wheel.

[0019] 2) Around the inner layer

[0020] With the help of the rope loop auxiliary guide wheel, the front end of the steel rope is wound into a rope loop with more than one turn;

[0021] 3) Fix the starting point and the rope end.

[0022] After the inner layer of the rope loop is wound, connect the starting point of the outer loop and the end of the steel rope to the inner layer respectively, and fix them by soldering.

[0023] 4) Around the outer layer

[0024] The driving wheel drives the driven wheel to start rotating, winding around the outer layer; starting from the outer winding starting point, the rear section of the steel rope continues to wind around the inner layer to form an outer winding layer with more than one turn, covering the outer winding starting point and the inner layer steel rope end;

[0025] 5) Circuit breaker

[0026] The magnetic guide wheel on the driven wheel can store the length of wire to be laid. Since the linear speed of the magnetic guide wheel is greater than the linear speed of the outer winding, the stored length of wire to be laid also increases until the length of wire to be laid reaches the required length of the rope loop. At the same time, the fuse at the exit of the traction wheel melts the steel rope, and the traction wheel and the wire laying I-beam stop. The melting always occurs at some point in the process of winding the outer layer.

[0027] 6) Steel rope end treatment

[0028] Secure the end of the outer steel rope by inserting a rope loop or soldering it in place.

[0029] Preferably, in step 5), a fuse is used to melt the steel rope.

[0030] The beneficial effects of this invention are:

[0031] This invention relates to a seamless, self-sealing rope loop made of a single, looped steel rope. The rope is held in place by friction between the inner and outer layers, with the rope end and outer winding starting point firmly encased inside. There are no joints or welds, and the entire production process does not compromise the rope's strength. The tensile strength of the rope loop is approximately equal to the product of the number of circumferential steel rope strands and the tensile strength of a single strand. Among existing connection methods, the rope loop described in this invention offers the highest connection strength.

[0032] As a cutting material, the rope loop of this invention, due to its structure of inner and outer layers winding, has several advantages over a single diamond wire or diamond rope. First, the length required for the cutting process can be reduced by 3,000 to 10,000 times, which undoubtedly greatly reduces the raw material cost for manufacturers. Second, the rope loop has no welding, no joints, and no strength loss, and can withstand tens of times higher tension and cutting intensity than normal processes during use.

[0033] When used as a skeleton material for reinforcement, transmission belts, synchronous belts, etc., the rope loop of the present invention has the characteristics of no joints, no welding, and uniform strength without loss throughout the loop, which can greatly improve the tensile strength, service life and other properties of the product.

[0049] Furthermore, it also includes a fuse 9, which is located in front of or behind the guide wheel 3.

[0050] The method for manufacturing a seamless self-sealing steel rope loop for cutting according to the present invention includes the following steps:

[0051] 1) Laying out the lines
