Description

Technical Field

[0001] This invention relates to the field of chain heat treatment technology, and in particular to a device for testing the hardness of stainless steel angle bars. Background Technology

[0002] A chain is a mechanical device that transmits motion and force through a series of interconnected links. It is typically made of steel or other durable materials and is widely used in bicycles, motorcycles, industrial equipment, conveyor belts, and other applications. The chain transmits power by meshing with other components through sprockets. Chain heat treatment refers to the process of heating, holding, and cooling the chain material to improve its mechanical properties, increase wear resistance, and extend its service life. Heat treatment can adjust key properties of the chain such as hardness, strength, and toughness, making it more suitable for use in high-load, high-wear, and harsh environments. Before heat treatment, the chain needs to be thoroughly cleaned to prevent affecting the heat treatment effect; existing heat treatment devices are usually not fully automated and continuous, resulting in low automation and poor continuity. Summary of the Invention

[0003] To address the aforementioned technical problems, the present invention adopts the following technical solution: a continuous heat treatment apparatus for chains, comprising a drive device for driving the chain, the drive device comprising a housing, and the drive device being provided with a front cleaning device and a side cleaning device for cleaning the front and sides of the chain respectively, the front cleaning device comprising an entry sprocket and a lower winding sprocket, the side cleaning device comprising a transfer sprocket, the transfer sprocket being rotatably mounted inside the housing;

[0004] The drive device includes a normalizing ring, and a drive sprocket, a quenching sprocket and an upper sprocket are rotatably installed inside the housing. The chain enters from above the entry sprocket, passes around the lower winding sprocket and the bottom of the transmission sprocket, passes through the normalizing ring and above the upper sprocket, then passes below the quenching sprocket, and finally passes above the drive sprocket. The drive sprocket drives the chain to move.

[0005] Furthermore, the drive device also includes a motor fixedly mounted on the housing, a drive shaft fixedly mounted on the drive sprocket, a drive belt wound around the drive shaft and the motor shaft, and a quenching tank provided inside the housing, which is filled with cooling oil.

[0006] Furthermore, a fixed frame is fixedly installed inside the outer shell, a normalizing ring is rotatably installed on the fixed frame, a lower eccentric disk is rotatably installed on the fixed frame, a worm gear is fixedly installed on the lower eccentric disk, a worm wheel is fixedly installed on the outside of the normalizing ring, the worm wheel meshes with the worm gear, a transmission connecting rod is eccentrically rotatably installed on the lower eccentric disk, an upper eccentric disk is fixedly installed on the upper sprocket, and the transmission connecting rod is eccentrically rotatably installed with the upper eccentric disk.

[0007] Furthermore, a gas box is fixedly installed inside the outer shell, and four gas outlets are provided inside the normalizing ring. The normalizing ring has a hollow structure, and the inner space of the normalizing ring is connected to the gas box through a pipe. An igniter for ignition is fixedly installed on the mounting bracket.

[0008] The motor rotates, driving the drive shaft and drive sprocket via a drive belt, which in turn drives the chain. The chain drives the quenching sprocket, upper sprocket, transmission sprocket, lower winding sprocket, and entry sprocket to rotate. The rotation of the upper sprocket drives the upper eccentric disc to rotate, which in turn drives the lower eccentric disc and worm gear to rotate via a transmission connecting rod, thereby driving the worm gear and normalizing ring to rotate. After being cleaned by the front cleaning device and the side cleaning device, the chain enters the normalizing ring. The gas box provides gas, which is released from the gas outlet and ignited by the igniter. The chain is normalized in the normalizing ring. The rotation of the normalizing ring enhances the normalizing effect. After normalizing, the chain enters the quenching tank for quenching. The cooling oil carried on the chain is blown back into the quenching tank by an air gun.

[0009] Furthermore, the forward cleaning device includes a forward cleaning frame fixedly installed inside the housing, an entry sprocket and a lower winding sprocket rotatably mounted on the forward cleaning frame, two cleaning shafts rotatably mounted on the forward cleaning frame, cleaning wheels fixedly mounted on the cleaning shafts, and drive belts wound around the entry sprocket and the lower winding sprocket respectively with the two cleaning shafts.

[0010] The chain passes between the two sweeping wheels. When the inlet sprocket and the lower sprocket are driven by the chain, they drive the two sweeping wheels to rotate through the transmission belt. Since the diameter of the sweeping shaft is smaller than that of the inlet sprocket and the lower sprocket, the sweeping wheels rotate at a faster speed. In conjunction with the water spray gun, the sweeping wheels clean the front and back of the chain.

[0011] Furthermore, the side cleaning device includes an upper and lower sliding frame fixedly installed inside the housing. Two side cleaning brushes are slidably installed on the upper and lower sliding frames. A sliding column is fixedly installed on the side cleaning brush. A grooved rod is rotatably installed on the front cleaning frame. A long groove is provided on the grooved rod. An eccentric wheel is fixedly installed on the transmission sprocket. An eccentric column is eccentrically fixedly installed on the eccentric wheel. The eccentric column and the sliding column slide in the long groove of the grooved rod.

[0012] The chain drives the transmission sprocket to rotate, which in turn drives the eccentric column to rotate. The eccentric column drives the grooved rod to rotate around the front sweeper frame, which in turn drives the sliding column and the side sweeping brush to rise and fall continuously. The side sweeping brush cleans both sides of the chain.

[0013] Furthermore, the outer shell is provided with an inlet shell, and a water spray gun and an air spray gun are provided inside the outer shell. The water spray gun sprays cleaning water onto the cleaning wheel, and the air spray gun is used to blow off the cooling oil carried on the quenched chain.

[0014] The beneficial effects of this invention compared with the prior art are: (1) The front cleaning device set in this invention fully cleans the front and back sides of the chain, then the side cleaning device fully cleans both sides of the chain, and finally the chain is normalized by the normalizing ring. Then the chain enters the quenching pool for quenching, realizing the fully automatic heat treatment of the chain with good continuity; (2) The water spray gun set in this invention washes the chain, and the cleaning wheel and side cleaning brush can fully clean all surfaces of the chain, improving the effect of subsequent chain heat treatment. The air gun blows down the cooling oil carried away by the chain after quenching, preventing the chain from carrying out a large amount of cooling oil; (3) The active sprocket set in this invention rotates to drive the chain to move automatically, and this power drives the front cleaning device, the side cleaning device and the normalizing ring to move, with a high degree of automation.

Detailed Implementation

[0025] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0026] Example: Reference Figures 1-9 A continuous heat treatment apparatus for chains includes a drive device for driving the chain. The drive device includes a housing 101. The drive device is provided with a front cleaning device and a side cleaning device for cleaning the front and side of the chain, respectively. The front cleaning device includes an entry sprocket 202 and a lower winding sprocket 203. The side cleaning device includes a transfer sprocket 301, which is rotatably installed inside the housing 101.

[0027] The drive device includes a normalizing ring 115. A drive sprocket 105, a quenching sprocket 106, and an upper sprocket 108 are rotatably mounted inside the housing 101. The chain enters from above the entry sprocket 202, passes around the lower winding sprocket 203 and below the transmission sprocket 301, passes through the normalizing ring 115 and above the upper sprocket 108, then passes below the quenching sprocket 106, and finally passes above the drive sprocket 105. The drive sprocket 105 drives the chain to move.

[0028] like Figures 3-5 As shown, the drive device also includes a motor 102 fixedly mounted on the housing 101, a drive shaft 104 fixedly mounted on the drive sprocket 105, a drive belt 103 wound around the drive shaft 104 and the motor shaft of the motor 102, and a quenching pool 107 provided inside the housing 101, which is filled with cooling oil.

[0029] like Figures 3-5As shown, a fixed bracket 113 is fixedly installed inside the outer casing 101. A normalizing ring 115 is rotatably installed on the fixed bracket 113. A lower eccentric disk 111 is rotatably installed on the fixed bracket 113. A worm gear 114 is fixedly installed on the lower eccentric disk 111. A worm wheel 118 is fixedly installed on the outside of the normalizing ring 115. The worm wheel 118 meshes with the worm gear 114. A transmission connecting rod 110 is eccentrically rotatably installed on the lower eccentric disk 111. An upper eccentric disk 109 is fixedly installed on the upper sprocket 108. The transmission connecting rod 110 and the upper eccentric disk 109 are eccentrically rotatably installed.

[0030] like Figures 3-5 As shown, a gas box 112 is fixedly installed inside the outer casing 101. Four gas outlets 117 are provided inside the normalizing ring 115. The normalizing ring 115 is a hollow structure. The inner space of the normalizing ring 115 is connected to the gas box 112 through a pipe. An igniter 116 for ignition is fixedly installed on the mounting bracket 113.

[0031] The rotation of motor 102 drives the rotation of drive shaft 104 and drive sprocket 105 via drive belt 103, thereby driving the chain to move. The chain drives the quenching sprocket 106, upper sprocket 108, transmission sprocket 301, lower winding sprocket 203, and entry sprocket 202 to rotate. The rotation of upper sprocket 108 drives the upper eccentric disk 109 to rotate, which in turn drives the lower eccentric disk 111 and worm gear 114 to rotate via transmission connecting rod 110, thereby driving the worm gear 118 and normalizing ring 115 to rotate. After being cleaned by the front cleaning device and the side cleaning device, the chain enters the normalizing ring 115. The gas box 112 provides gas, which is released from the gas outlet 117 and ignited by the igniter 116. The chain is normalized in the normalizing ring 115. The rotation of the normalizing ring 115 improves the normalizing effect. After normalizing, the chain enters the quenching tank 107 for quenching. The cooling oil carried on the chain is blown back into the quenching tank 107 by the jet gun 403.

[0032] like Figure 6 , Figure 7 As shown, the front cleaning device includes a front cleaning frame 201 fixedly installed inside the housing 101. An entry sprocket 202 and a lower winding sprocket 203 are rotatably mounted on the front cleaning frame 201. Two cleaning shafts 205 are rotatably mounted on the front cleaning frame 201. A cleaning wheel 204 is fixedly mounted on the cleaning shaft 205. A drive belt 206 is wound around the two cleaning shafts 205 on the entry sprocket 202 and the lower winding sprocket 203 respectively.

[0033] The chain passes between the two sweeping wheels 204. When the entering sprocket 202 and the lower winding sprocket 203 are driven by the chain, they drive the two sweeping wheels 204 to rotate through the transmission belt 206. Since the diameter of the sweeping shaft 205 is smaller than the diameter of the entering sprocket 202 and the lower winding sprocket 203, the sweeping wheel 204 rotates faster. With the water spray from the water gun 402, the sweeping wheel 204 cleans the front and back of the chain.

[0034] like Figure 8 , Figure 9 As shown, the side cleaning device includes an upper and lower slide frame 305 fixedly installed inside the housing 101. Two side cleaning brushes 307 are slidably installed on the upper and lower slide frame 305. A sliding column 306 is fixedly installed on the side cleaning brushes 307. A grooved rod 304 is rotatably installed on the front cleaning frame 201. The grooved rod 304 is provided with a long groove. An eccentric wheel 302 is fixedly installed on the transmission sprocket 301. An eccentric column 303 is eccentrically fixedly installed on the eccentric wheel 302. The eccentric column 303 and the sliding column 306 slide in the long groove of the grooved rod 304.

[0035] The chain drives the transmission sprocket 301 to rotate, which in turn drives the eccentric column 303 to rotate. The eccentric column 303 drives the groove rod 304 to rotate around the front cleaning frame 201, which in turn drives the sliding column 306 and the side cleaning brush 307 to continuously rise and fall. The side cleaning brush 307 cleans both sides of the chain.

[0036] like Figure 2 As shown, the outer casing 101 is provided with an inlet shell 401, and the outer casing 101 is provided with a water spray gun 402 and an air spray gun 403. The water spray gun 402 sprays cleaning water onto the cleaning wheel 204, and the air spray gun 403 is used to blow off the cooling oil carried on the quenched chain.

[0037] The working principle of the continuous heat treatment device for chains disclosed in this invention is as follows: the motor 102 rotates, driving the drive shaft 104 and drive sprocket 105 to rotate via the drive belt 103, thereby driving the chain to move. The chain drives the quenching sprocket 106, upper sprocket 108, transmission sprocket 301, lower winding sprocket 203 and entry sprocket 202 to rotate. The chain passes between two cleaning wheels 204. When the entry sprocket 202 and lower winding sprocket 203 are driven by the chain, they drive the two cleaning wheels 204 to rotate via the transmission belt 206. Since the diameter of the cleaning shaft 205 is smaller than the diameter of the entry sprocket 202 and lower winding sprocket 203, the cleaning wheel 204 rotates at a faster speed. With the water spray from the water gun 402, the cleaning wheel 204 cleans the front and back of the chain. The chain drives the transmission sprocket 301 to rotate, which in turn drives the eccentric column 303 to rotate. The eccentric column 303 drives the groove rod 304 to rotate around the front cleaning frame 201, which in turn drives the sliding column 306 and the side cleaning brush 307 to continuously rise and fall. The side cleaning brush 307 cleans both sides of the chain. The rotation of the upper sprocket 108 drives the upper eccentric disk 109 to rotate, which in turn drives the lower eccentric disk 111 and the worm gear 114 to rotate via the transmission connecting rod 110. This, in turn, drives the worm wheel 118 and the normalizing ring 115 to rotate. After being cleaned by the front cleaning device and the side cleaning device, the chain enters the normalizing ring 115. The gas box 112 provides gas, which is released from the gas outlet 117 and ignited by the igniter 116. The chain is normalized in the normalizing ring 115. The rotation of the normalizing ring 115 enhances the normalizing effect. After normalizing, the chain enters the quenching tank 107 for quenching. The cooling oil carried on the chain is blown back into the quenching tank 107 by the jet gun 403.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the present invention based on the technical solution and inventive concept of the present invention should be covered within the scope of protection of the present invention.
