Description

Technical Field

[0001] The present invention relates to the technical field of chain production, and specifically relates to a production process for high-temperature resistant chains. Background Art

[0002] The chain manufacturing ability is a decisive factor in the chain manufacturing industry, and the core of the chain manufacturing strength lies in the degree of the chain manufacturing process; the existing chain oiling method generally adopts the dipping method, that is, directly putting the chain into the oil liquid and then taking it out. The chain links are in a fitting state. Even when the chain is placed in the oil liquid, the connection part of the chain links still cannot contact the oil liquid, resulting in an oiling dead angle. The connection part of the chain links is not protected and is prone to oxidation, affecting the service life of the chain; however, after the chain is oiled, there is excess oil liquid on its surface. The traditional oil removal method cannot effectively remove the excess oil liquid on the chain surface, which is likely to affect its use and cause waste of the oil liquid at the same time. Summary of the Invention

[0003] The technical problems solved by this solution are as follows:

[0004] (1) How to set up an oiling mechanism to change the shape of the chain through two adjusting gears, so that the chain can fully contact with the lubricating oil, avoid dead angles when oiling the chain, protect the connection part of the chain, prevent the chain from oxidizing, and ensure the service life of the chain;

[0005] (2) How to set up a sponge block so that when the tooth section of the rack contacts the two sponge blocks, a small amount of lubricating oil will adhere to its surface, ensuring the lubricity between the rack and the two transmission gears and preventing jamming;

[0006] (3) How to set up a recovery mechanism to absorb the excess lubricating oil on the chain surface through a sponge sleeve, so as to perform the removal operation on the lubricating oil on the chain surface again and improve the recovery efficiency of the lubricating oil.

[0007] The object of the present invention can be achieved through the following technical solutions: A production process for high-temperature resistant chains, and the specific operation steps include:

[0008] Step 1: Use manufacturing equipment to make a rod into chain links, and at the same time put the chain links into grinding equipment for grinding to remove the rust on the surface of the chain links;

[0009] Step 2: Put the chain links after removing rust into heating equipment for heat treatment to eliminate stress in the chain links and change the internal structure. Introduce a carbon-containing medium to infiltrate carbon into the surface of the chain links to improve the hardness and high-temperature resistance of the chain. Then perform quenching on it, and then put the quenched chain links into assembly equipment for assembly and forming in sequence to obtain a chain;

[0010] Step 3: Chemically nickel-plate the chain. Chemically nickel-plating the chain will improve its high-temperature resistance, ensuring that the chain can still be used normally in a high-temperature environment. Then, transfer the nickel-plated chain to the oiling equipment for oiling. Apply lubricating oil to the surface of the chain to prevent it from rusting, making the chain more shiny and increasing its service life.

[0011] Step 4: Inspect the processed chain, remove the unqualified chains, and then pack and store the qualified chains.

[0012] A further technical improvement of the present invention is that in Step 3, a tension spring in the oiling equipment pulls the rotating rod, so that the adjusting gear on the rotating rod and the chain are always in a taut state.

[0013] A further technical improvement of the present invention is that in Step 3, two sponge blocks in the oiling equipment absorb the lubricating oil to oil the rack, ensuring smoothness between the transmission gear and the rack.

[0014] A further technical improvement of the present invention is that in Step 3, two rubber sheets in the oiling equipment remove the excess lubricating oil on the chain.

[0015] A further technical improvement of the present invention is that in Step 3, a sponge sleeve in the oiling equipment absorbs the excess lubricating oil on the chain again.

[0016] A further technical improvement of the present invention is that in Step 3, a pressing roller in the oiling equipment provides the pressing force for the pressing plate to squeeze out the lubricating oil in the sponge sleeve.

[0017] A further technical improvement of the present invention is that the oiling equipment includes an oil storage tank. On the outer walls on both sides of the oil storage tank, a first guide frame and a second guide frame for driving the chain are respectively fixedly installed. On the back of the inner wall of the oil storage tank, an oiling mechanism is provided, and on one side of the oiling mechanism, a recovery mechanism for removing the excess lubricating oil on the surface of the chain is provided.

[0018] A further technical improvement of the present invention lies in that: the oiling mechanism includes a mounting plate fixedly connected to the oil storage tank. Two adjusting units are symmetrically arranged on the front surface of the mounting plate. The adjusting unit includes a limiting sleeve rotatably connected to the mounting plate through a bearing. A rotating rod is movably sleeved in the limiting sleeve. An adjusting gear is rotatably arranged at the bottom end of the rotating rod. The adjusting gear is meshed with a chain. A limiting block is fixedly connected to the top end of the rotating rod. A tension spring is arranged between the limiting block and the limiting sleeve. When the rotating rod rotates, the rotating rod is pulled by the tension spring to slide in the limiting sleeve, so that the adjusting gear and the chain are in a tensioned state, preventing the chain from being disengaged from the adjusting gear. A rotating gear is also rotatably arranged on the front surface of the mounting plate. The rotating gear is meshed with the chain. A transmission unit for driving the two adjusting units is arranged on the back surface of the mounting plate.

[0019] A further technical improvement of the present invention lies in that: the transmission unit includes two rotating shafts movably inserted into the mounting plate. One ends of the two rotating shafts are fixedly connected to the corresponding limiting sleeves. The other ends of the rotating shafts are fixedly connected with transmission gears. A rack is commonly meshed between the two transmission gears. A first limiting ring and a second limiting ring are fixedly connected to the mounting plate. Two ends of the rack respectively movably penetrate through the first limiting ring and the second limiting ring. Two sponge blocks are symmetrically arranged at the top of the second limiting ring. The distance between the two sponge blocks is less than the width of the rack. And the bottoms of the two sponge blocks are both immersed in the lubricant. When the tooth section of the rack contacts the two sponge blocks, a small amount of lubricating oil will adhere to its surface. When the rack rises, the tooth section of the rack meshes with the two transmission gears, and the lubricating oil will also adhere to the two transmission gears, ensuring the lubricity between the rack and the two transmission gears and preventing jamming. A power mechanism for driving the rack to reciprocate up and down is also arranged on the top of the mounting plate.

[0020] A further technical improvement of the present invention lies in that: the power mechanism includes a pin shaft fixedly connected to the mounting plate. One end of the pin shaft is rotatably provided with a rotating plate. Chute grooves are respectively opened on both sides of the rotating plate. A driving motor is fixedly installed on the mounting plate. The output end of the driving motor is fixedly connected with a rotating arm. One end of the rotating arm is movably connected to one of the chute grooves through a first dial rod. The top end of the rack is movably connected to the other chute groove through a second dial rod. A pressing roller is rotatably arranged at one end of the rotating plate close to the driving motor. By operating the driving motor to drive the rotating arm to rotate, the rotating plate swings reciprocally, thereby driving the rack to reciprocate up and down. At the same time, cooperating with the two transmission gears to drive the two rotating shafts to rotate. The two limiting sleeves respectively drive the corresponding rotating rods to rotate, so that the two adjusting gears change the shape of the chain, enabling the chain to fully contact with the lubricating oil, avoiding dead corners when the chain is oiled, protecting the joints of the chain, preventing the chain from oxidizing, and ensuring the service life of the chain.

[0021] A further technical improvement of the present invention lies in that: the recovery mechanism includes a recovery tank fixedly connected to the inner wall of the oil storage tank. The recovery tank is inclined. An absorption unit for further absorbing excess lubricating oil is arranged in the recovery tank. A plurality of oil leakage holes are opened in the middle of the bottom of the recovery tank. Two rubber sheets symmetrical about the chain are arranged at the bottom end of the recovery tank. One of the rubber sheets is fixedly connected to the mounting plate, and the other rubber sheet is fixedly connected to the recovery tank. The surfaces of the two rubber sheets facing the chain are arc-shaped, and both rubber sheets are in close contact with the chain. The excess lubricating oil on the surface of the chain is scraped off by the two rubber sheets, avoiding the influence of the excess lubricating oil on the use of the chain. At the same time, it will also reduce the use of lubricating oil, reduce energy consumption, and reduce the cost of oiling the chain.

[0022] A further technical improvement of the present invention lies in that: the absorption unit includes two guide plates fixedly installed on the bottom of the recovery tank. A pressing plate is slidably arranged between the two guide plates. Two guide rails are fixedly installed on the side surfaces of the two guide plates facing the pressing plate. Each guide rail is slidably connected to the pressing plate. A sponge sleeve is arranged on the side surface of the pressing plate facing the recovery tank. A sleeve hole is opened inside the sponge sleeve. The chain movably penetrates through the sleeve hole of the sponge sleeve, and the cross-sectional area of the chain is larger than the area of the sleeve hole of the sponge sleeve. The chain with the lubricating oil scraped by the two rubber sheets penetrates through the sponge sleeve. The excess lubricating oil on the surface of the chain is absorbed by the sponge sleeve, so as to perform the removal operation on the lubricating oil on the surface of the chain again, improving the recovery efficiency of the lubricating oil. When the rotating plate swings reciprocally, the pressing roller presses the pressing plate to roll, so that the pressing plate fully presses the sponge sleeve, and the absorbed lubricating oil inside is squeezed out, avoiding the reduction of the efficiency of absorbing lubricating oil by the sponge sleeve after the sponge sleeve is saturated with absorbing lubricating oil.

[0023] A further technical improvement of the present invention lies in that: a plurality of the oil leakage holes are all inclined relative to the recovery tank, and the bottom ends of the oil leakage holes are located above the oil storage tank; it is convenient to quickly guide the lubricating oil flowing in the recovery tank back into the oil storage tank.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] When the present invention is in use, the driving motor operates to drive the rotating arm to rotate, so that the rotating plate swings reciprocally, thereby driving the rack to lift reciprocally. At the same time, two transmission gears are cooperated to drive two rotating shafts to rotate. Two limit sleeves respectively drive the corresponding rotating rods to rotate, so that two adjusting gears change the shape of the chain, making the chain come into full contact with the lubricating oil, avoiding dead angles when oiling the chain, protecting the joints of the chain, preventing the chain from oxidizing, and ensuring the service life of the chain.

[0026] When the present invention is in use, when the rotating rod rotates, the rotating rod is pulled by the tension spring to slide within the limit sleeve, so that the adjusting gear and the chain are in a taut state, preventing the chain from becoming disengaged from the adjusting gear. When the tooth section of the rack contacts the two sponge blocks, a small amount of lubricating oil will adhere to its surface. When the rack rises, the tooth section of the rack meshes with the two transmission gears, and the lubricating oil will also adhere to the two transmission gears, ensuring the lubricity between the rack and the two transmission gears and preventing jamming.

[0027] When the present invention is in use, the sponge sleeve absorbs the excess lubricating oil on the surface of the chain, so that the lubricating oil on the surface of the chain is removed again, improving the recovery efficiency of the lubricating oil. When the rotating plate swings back and forth, the pressing roller presses the pressing plate by rolling, so that the pressing plate fully presses the sponge sleeve and squeezes out the lubricating oil absorbed inside it, avoiding the reduction of the efficiency of the sponge sleeve to absorb the lubricating oil due to the saturation of the sponge sleeve with the lubricating oil.

[0045] Please refer to Figure 1As shown in the figure, in the above step three, the two rotating rods 405 in the oiling device swing reciprocally, driving the adjusting gear 403 to change the shape of the chain, so that each connection of the chain rotates, and the lubricating oil is in full contact with the chain; in step three, the tension spring 402 in the oiling device pulls the rotating rod 405, so that the adjusting gear 403 on the rotating rod 405 and the chain are always in a taut state; in step three, the two sponge blocks 411 in the oiling device absorb the lubricating oil to oil the rack 409, ensuring smoothness between the transmission gear 413 and the rack 409; in step three, the two rubber sheets 503 in the oiling device remove the excess lubricating oil on the chain; in step three, the sponge sleeve 5043 in the oiling device absorbs the excess lubricating oil on the chain again; in step three, the pressing roller 4083 in the oiling device provides pressing power to the pressing plate 5044 to squeeze out the lubricating oil in the sponge sleeve 5043.

[0046] Please refer to Figure 2 As shown in the figure, the oiling device includes an oil storage tank 2. On the outer walls on both sides of the oil storage tank 2, a first guide frame 1 and a second guide frame 3 for driving the chain are respectively fixedly installed. On the back of the inner wall of the oil storage tank 2, an oiling mechanism 4 is provided. On one side of the oiling mechanism 4, a recovery mechanism 5 for removing the excess lubricating oil on the surface of the chain is provided.

[0047] Please refer to Figure 3 and Figure 4 As shown in the figure, the above-mentioned oiling mechanism 4 includes a mounting plate 401 fixedly connected to the oil storage tank 2. Two adjusting units are symmetrically arranged on the front of the mounting plate 401. The adjusting unit includes a limiting sleeve 406 rotatably connected to the mounting plate 401 through a bearing. A rotating rod 405 is movably sleeved in the limiting sleeve 406. At the bottom end of the rotating rod 405, an adjusting gear 403 is rotatably arranged. The adjusting gear 403 is meshed with the chain. At the top end of the rotating rod 405, a limiting block 407 is fixedly connected. A tension spring 402 is arranged between the limiting block 407 and the limiting sleeve 406; when the rotating rod 405 rotates, the tension spring 402 pulls the rotating rod 405 to slide in the limiting sleeve 406, so that the adjusting gear 403 and the chain are in a taut state, preventing the chain from being disconnected from the adjusting gear 403. A rotating gear 404 is also rotatably arranged on the front of the mounting plate 401. The rotating gear 404 is meshed with the chain. On the back of the mounting plate 401, a transmission unit for driving the two adjusting units is provided.

[0048] Please refer to Figure 4 and Figure 5As shown in the figure, the above-mentioned transmission unit includes two rotating shafts 410 movably inserted on the mounting plate 401. One end of each of the two rotating shafts 410 is fixedly connected to the corresponding limiting sleeve 406, and the other end of the rotating shaft 410 is fixedly connected to a transmission gear 413. A rack 409 is meshed and connected between the two transmission gears 413. A first limiting ring and a second limiting ring 412 are fixedly connected to the mounting plate 401. Both ends of the rack 409 movably penetrate through the first limiting ring and the second limiting ring 412 respectively. Two sponge blocks 411 are symmetrically arranged on the top of the second limiting ring 412. The distance between the two sponge blocks 411 is less than the width of the rack 409, and the bottoms of the two sponge blocks 411 are both immersed in the lubricant. When the tooth section of the rack 409 contacts the two sponge blocks 411, a small amount of lubricating oil will adhere to its surface. When the rack 409 rises, the tooth section of the rack 409 meshes with the two transmission gears 413, and the lubricating oil will also adhere to the two transmission gears 413, ensuring the lubricity between the rack 409 and the two transmission gears 413 and preventing jamming. A power mechanism 408 for driving the rack 409 to reciprocate up and down is also provided on the top of the mounting plate 401.

[0049] Please refer to Figure 6 As shown in the figure, the above-mentioned power mechanism 408 includes a pin shaft 4081 fixedly connected to the mounting plate 401. One end of the pin shaft 4081 is rotatably provided with a rotating plate 4085. Sliding grooves are formed on both sides of the rotating plate 4085. A driving motor 4084 is fixedly installed on the mounting plate 401. The output end of the driving motor 4084 is fixedly connected to a rotating arm 4082. One end of the rotating arm 4082 is movably connected to one of the sliding grooves through a first dial rod. The top end of the rack 409 is movably connected to the other sliding groove through a second dial rod. A pressing roller 4083 is rotatably provided at one end of the rotating plate 4085 close to the driving motor 4084. By operating the driving motor 4084 to drive the rotating arm 4082 to rotate, the rotating plate 4085 makes a reciprocating swing, thereby driving the rack 409 to reciprocate up and down. At the same time, cooperating with the two transmission gears 413 to drive the two rotating shafts 410 to rotate, the two limiting sleeves 406 respectively drive the corresponding rotating rods 405 to rotate, so that the two adjusting gears 403 change the shape of the chain, enabling the chain to come into full contact with the lubricating oil, avoiding dead corners when the chain is oiled, protecting the joints of the chain, preventing the chain from oxidizing, and ensuring the service life of the chain.

[0050] Please refer to Figure 2 and Figure 7As shown in the figure, the above-mentioned recovery mechanism 5 includes a recovery tank 501 fixedly connected to the inner wall of the oil storage tank 2. The recovery tank 501 is inclined. An absorption unit 504 for further absorbing excess lubricating oil is arranged in the recovery tank 501. A plurality of oil leakage holes 502 are opened in the middle of the bottom of the recovery tank 501. Two rubber sheets 503 symmetric about the chain are arranged at the bottom end of the recovery tank 501. One of the rubber sheets 503 is fixedly connected to the mounting plate 401, and the other rubber sheet 503 is fixedly connected to the recovery tank 501. The surfaces of the two rubber sheets 503 facing the chain are arc-shaped, and both rubber sheets 503 are in close contact with the chain. The excess lubricating oil on the surface of the chain is scraped off by the two rubber sheets 503, which can avoid the influence of excess lubricating oil on the use of the chain. At the same time, it can also reduce the use of lubricating oil, reduce energy consumption, and lower the cost of oiling the chain.

[0051] Please refer to Figure 8 and Figure 9 As shown in the figure, the above-mentioned absorption unit 504 includes two guide plates 5041 fixedly installed on the bottom of the recovery tank 501. A pressing plate 5044 is slidably arranged between the two guide plates 5041. Two guide rails 5042 are fixedly installed on the side surfaces of the two guide plates 5041 facing the pressing plate 5044. Each guide rail 5042 is slidably connected to the pressing plate 5044. A sponge sleeve 5043 is arranged on the side surface of the pressing plate 5044 facing the recovery tank 501. A sleeve hole is opened inside the sponge sleeve 5043. The chain passes through the sleeve hole of the sponge sleeve 5043 movably, and the cross-sectional area of the chain is larger than the area of the sleeve hole of the sponge sleeve 5043. The chain with the lubricating oil scraped by the two rubber sheets 503 passes through the sponge sleeve 5043. The excess lubricating oil on the surface of the chain is absorbed by the sponge sleeve 5043, so as to remove the lubricating oil on the surface of the chain again and improve the recovery efficiency of the lubricating oil. When the rotating plate 4085 swings back and forth, the pressing roller 4083 presses the pressing plate 5044 by rolling, so that the pressing plate 5044 fully presses the sponge sleeve 5043 and squeezes out the lubricating oil absorbed inside it, avoiding the reduction of the efficiency of the sponge sleeve 5043 in absorbing lubricating oil after being saturated with lubricating oil.

[0052] Please refer to Figure 7 As shown in the figure, the above-mentioned plurality of oil leakage holes 502 are all inclined relative to the recovery tank 501, and the bottom ends of the oil leakage holes 502 are located above the oil storage tank 2; this facilitates quickly guiding the lubricating oil flowing in the recovery tank 501 back into the oil storage tank 2.

[0053] Working principle: When the present invention is in use, first, the driving motor 4084 operates to drive the rotating arm 4082 to rotate, causing the rotating plate 4085 to swing reciprocally, thereby driving the rack 409 to reciprocally lift. At the same time, two transmission gears 413 cooperate to drive two rotating shafts 410 to rotate. Two limit sleeves 406 respectively drive the corresponding rotating rods 405 to rotate, causing the two adjusting gears 403 to change the form of the chain, enabling the chain to fully contact the lubricating oil, avoiding dead corners when oiling the chain, protecting the joints of the chain, preventing the chain from oxidizing, and ensuring the service life of the chain; when the rotating rod 405 rotates, the tension spring 402 pulls the rotating rod 405 to slide within the limit sleeve 406, causing the adjusting gear 403 and the chain to be in a taut state, preventing the chain from becoming disengaged from the adjusting gear 403. When the toothed section of the rack 409 contacts the two sponge blocks 411, a small amount of lubricating oil will adhere to its surface. When the rack 409 ascends, the toothed section of the rack 409 meshes with the two transmission gears 413, and the lubricating oil will also adhere to the two transmission gears 413, ensuring the lubricity between the rack 409 and the two transmission gears 413 and preventing jamming; the chain that has been scraped by the two rubber sheets 503 passes through the sponge sleeve 5043, and the sponge sleeve 5043 absorbs the excess lubricating oil on the surface of the chain, enabling the removal operation of the lubricating oil on the chain surface again and improving the recovery efficiency of the lubricating oil. When the rotating plate 4085 swings reciprocally, the pressing roller 4083 presses the extrusion plate 5044 by rolling, causing the extrusion plate 5044 to fully press the sponge sleeve 5043 and squeeze out the lubricating oil absorbed inside it, avoiding the reduction in the efficiency of the sponge sleeve 5043 to absorb lubricating oil due to saturation of the sponge sleeve 5043 with lubricating oil.
