Description

Technical Field

[0001] The utility model relates to the technical field of round link chain manufacturing, in particular to a hot dip plating device for a high-strength round link chain. Background Art

[0002] In addition to meeting the strength requirements, some special-purpose round link chains must also have excellent anti-corrosion and wear-resistant properties. At present, when coating the surface of high-strength round link chains with an anti-corrosion and wear-resistant layer, an immersion treatment process is generally used. However, this process is time-consuming, inefficient, and only suitable for short-length round link chains. Otherwise, the plating liquid container must be enlarged, which will bring problems in various aspects such as the medium melting time, the frequency of plating liquid replenishment, slag removal, and even the overhaul and maintenance of the device.

[0003] In order to improve the efficiency of hot-dip plating of round-link chains, the existing technology adopts a continuous hot-dip plating process to ensure the quality of hot-dip plating of round-link chains while keeping the same rhythm with pre-plating and post-plating processes. However, the existing technical problem is that since the round-link chain is in a taut state when it passes through the plating solution continuously, the gap between the chain links is small, and the plating solution has a large viscosity and poor fluidity, making it difficult to fully immerse the chain link connection. Although there are many types of plating aids as auxiliary, plating leakage still often occurs. Utility Model Content

[0004] The utility model aims to provide a hot dip plating device for high-strength round link chains, which can realize full dip plating of the round link chains in a hot dip plating tank, and reduce the missed plating area by slowing down the round link chains in the hot dip plating tank and adjusting the degree of relaxation at the same time.

[0005] The above technical objectives of the utility model are achieved through the following technical solutions:

[0006] A hot dip coating device for a high-strength round link chain, characterized in that it comprises a chain feed guide wheel, a chain collection guide wheel, a hot dip coating pool and a guide block, the chain feed guide wheel and the chain collection guide wheel are respectively arranged on both sides of the hot dip coating pool, the guide block comprises a first guide block and a second guide block, the first guide block and the second guide block are respectively arranged below the chain feed guide wheel and the chain collection guide wheel on both sides of the hot dip coating pool, a guide groove is vertically penetrated in the first guide block and the second guide block, the round link chain passes through the chain feed guide wheel, the first guide block, the hot dip coating pool, the second guide block and the chain collection guide wheel in sequence, and the bottoms of the first guide block and the second guide block are installed on both sides of the hot dip coating pool through a reciprocating assembly.

[0007] Preferably, in a working state, the chain-feeding speed of the chain-feeding guide wheel is the same as the chain-collecting speed of the chain-collecting guide wheel.

[0008] Preferably, the guide groove is arranged as a cross through hole, and the size of the guide groove is larger than the round link chain.

[0009] Preferably, the reciprocating component includes a mounting seat, a rotating motor, a fixed seat, a crank arm and a connecting rod. The first guide block and the second guide block are both detachable and fixedly mounted on the mounting seat. A slider is provided at the bottom of the mounting seat. The slider moves back and forth along the inside of the slide rail. The two ends of the connecting rod are respectively movably connected to the mounting seat and one end of the crank arm. One end of the crank arm is connected to the output end of the rotating motor. The rotating motor is mounted on both sides of the hot dip plating tank through the fixed seat.

[0010] Preferably, the fixing seat connected to the first guide block and the second guide block moves in opposite directions relative to each other.

[0011] Preferably, a limiting oil cylinder is also provided above the second guide block.

[0016] A limit oil cylinder is obliquely arranged above the second guide block of the utility model, which can form a card limit for the chain links of different setting directions of the round link chain. At this time, the chain feed guide wheel continues to feed the chain, and the chain collection guide wheel stops working, so that the front section of the round link chain is in a relaxed state, thereby exposing the connection between adjacent chain links, thereby reducing the plating leakage area, and subsequently the chain feed guide wheel stops working, and the chain collection guide wheel continues to collect the chain to continue to complete the hot dip plating.

[0020] The following is a clear and complete description of the technical solutions in the embodiments of the utility model patent in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the utility model patent, not all of them. Based on the embodiments in the utility model patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model patent.

[0021] like Figures 1 to 3 A hot dip plating device for a high-strength round link chain is shown, comprising a chain feed guide wheel 1, a chain collection guide wheel 2, a hot dip plating pool 3 and a guide block. The chain feed guide wheel 1 and the chain collection guide wheel 2 are respectively arranged on both sides of the hot dip plating pool 3. The guide blocks comprise a first guide block 4 and a second guide block 5. The first guide block 4 and the second guide block 5 are respectively arranged below the chain feed guide wheel 1 and the chain collection guide wheel 2 on both sides of the hot dip plating pool 3. A guide groove 6 is vertically penetrated in the first guide block 4 and the second guide block 5. The round link chain 7 passes through the chain feed guide wheel 1, the first guide block 4, the hot dip plating pool 3, the second guide block 5 and the chain collection guide wheel 2 in sequence. The bottoms of the first guide block 4 and the second guide block 5 are installed on both sides of the hot dip plating pool 3 through a reciprocating assembly.

[0022] In the working state, the chain-feeding speed of the chain-feeding guide wheel 1 is the same as the chain-collecting speed of the chain-collecting guide wheel 2.

[0023] The guide groove 6 is a cross through hole, and the size of the guide groove 6 is larger than the round link chain 7, so as to avoid the jamming during the activity of the cyclic reciprocating component, thereby affecting the hot dip plating of the round link chain.

[0024] The reciprocating component includes a mounting seat 8, a rotating motor 9, a fixed seat 10, a crank arm 11 and a connecting rod 12. The first guide block 4 and the second guide block 5 can be detachably fixed on the mounting seat 8. A slider 13 is provided at the bottom of the mounting seat 8. The slider 13 moves back and forth along the inside of the slide rail 14. The two ends of the connecting rod 12 are respectively movably connected to the mounting seat 8 and one end of the crank arm 11. One end of the crank arm 11 is connected to the output end of the rotating motor 9. The rotating motor 9 is installed on both sides of the hot dip plating pool 3 through the fixed seat 10.

[0025] The fixing seat 10 connected to the first guide block 4 and the second guide block 5 moves in opposite directions relative to each other, so that the circular link chain in the hot dip plating pool is always in a shaking state. Later, a larger swing can be achieved by adjusting the cycle time of the reciprocating cycle, so that the places between the circular link chains that are prone to plating leakage can be exposed, and the hot dip plating effect is better.

[0026] A limiting oil cylinder 15 is also arranged above the second guide block 5. The limiting oil cylinder 15 is arranged at one corner of the second guide block 5 and is arranged obliquely as a whole. A positioning block 16 is arranged at another corner of the second guide block 5 relative to the limiting oil cylinder 15. The limiting oil cylinder 15 passes through the hole groove in the round link chain 7 and is fixed with the positioning block 16.

[0027] A baffle 17 is arranged around the circular chain 7 below the second guide block 5, and the bottom height of the baffle 17 is arranged below the pool mouth of the hot dip plating pool 3, which can prevent the circular chain that has completed hot dip plating from throwing out the plating liquid during the swinging process, thereby affecting the working environment.

[0028] Reinforcement plates 18 are provided at the connections between the mounting seat 8 and the first guide block 4 and the second guide block 5, so that the structure is more stable.

[0029] The utility model drives the first guide block and the second guide block to move by two sets of circulating ring reciprocating components that move in opposite directions relative to each other, so that the circular chain in the hot dip plating pool is always in a shaking state, so that the places between the circular chain that are prone to plating leakage can be exposed, and the hot dip plating effect is better.

[0030] A limit oil cylinder is obliquely arranged above the second guide block of the utility model, which can form a card limit for the chain links of different setting directions of the round link chain. At this time, the chain feed guide wheel continues to feed the chain, and the chain collection guide wheel stops working, so that the front section of the round link chain is in a relaxed state, thereby exposing the connection between adjacent chain links, thereby reducing the plating leakage area, and subsequently the chain feed guide wheel stops working, and the chain collection guide wheel continues to collect the chain to continue to complete the hot dip plating.
