Description

Technical Field

[0001] The invention relates to the technical field of chain heat treatment, and in particular to a stainless steel angle steel hardness detection device. Background Art

[0002] A chain is a mechanical device that transmits motion and force through a series of connected links. It is usually made of steel or other durable materials and is widely used in bicycles, motorcycles, industrial equipment, conveyor belts and other occasions. The chain engages with other components through sprockets to transmit power. Chain heat treatment refers to the process of heating, insulating and cooling the chain material to improve the mechanical properties of the chain, improve wear resistance and extend the service life. Heat treatment can adjust the 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. The chain needs to be fully cleaned before heat treatment to prevent affecting the heat treatment effect of the chain; the line heat treatment device obtained in the prior art is usually not able to be fully automatic and continuous, with a low degree of automation and poor continuity. Summary of the invention

[0003] In view of the above technical problems, the technical solution adopted by the present invention is: a continuous heat treatment device for a chain, comprising a driving device for driving the chain, the driving device comprising a housing, the driving device being 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 comprising an entry sprocket and a lower winding sprocket, the side cleaning device comprising a transmission sprocket, and the transmission sprocket being rotatably mounted in the housing; The driving device includes a normalizing ring, a driving sprocket, a quenching sprocket and an upper sprocket rotatably installed in a shell, the chain enters from above the entry sprocket, passes around the lower winding sprocket and below the transfer sprocket, the chain passes through the normalizing ring and passes from above the upper sprocket, then passes from below the quenching sprocket, and finally passes from above the driving sprocket, and the driving sprocket drives the chain to move.

[0004] Furthermore, the driving device also includes a motor fixedly mounted on the housing, a driving shaft fixedly mounted on the driving sprocket, a driving belt wrapped around the driving shaft and the motor shaft of the motor, a quenching pool is arranged in the housing, and cooling oil is filled in the quenching pool.

[0005] Furthermore, a fixing frame is fixedly installed in the outer shell, a normalizing ring is rotatably installed on the fixing frame, a lower eccentric disk is rotatably installed on the fixing frame, a worm is fixedly installed on the lower eccentric disk, a worm wheel is fixedly installed on the outer side of the normalizing ring, the worm wheel is meshed with the worm, 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 and the upper eccentric disk are eccentrically rotatably installed.

The chain enters from above the entrance sprocket 202, and passes around the lower winding sprocket 203 and the bottom of the transfer sprocket 301. The chain passes through the normalizing ring 115 and passes from above the upper sprocket 108, then passes from below the quenching sprocket 106, and finally passes from above the driving sprocket 105. The driving sprocket 105 drives the chain to move.

[0027] like Figure 3-Figure 5As shown, a fixing frame 113 is fixedly installed in the outer shell 101, a normalizing ring 115 is rotatably installed on the fixing frame 113, a lower eccentric disk 111 is rotatably installed on the fixing frame 113, a worm 114 is fixedly installed on the lower eccentric disk 111, a worm wheel 118 is fixedly installed on the outer side of the normalizing ring 115, the worm wheel 118 is meshed with the worm 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, and the transmission connecting rod 110 and the upper eccentric disk 109 are eccentrically rotatably installed.

[0028] like Figure 3-Figure 5 As shown, a gas box 112 is fixedly installed in the outer shell 101, four air outlet holes 117 are provided in 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 pipeline, and an igniter 116 for ignition is fixedly installed on the fixing frame 113.

[0029] The motor 102 rotates to drive the driving shaft 104 and the driving sprocket 105 through the driving belt 103, thereby driving the chain to move, and the chain drives the quenching sprocket 106, the upper sprocket 108, the transfer sprocket 301, the lower winding sprocket 203 and the entry sprocket 202 to rotate, and the upper sprocket 108 rotates to drive the upper eccentric disk 109 to rotate, and drives the lower eccentric disk 111 and the worm 114 to rotate through the transmission connecting rod 110, thereby driving the worm wheel 118 and the normalizing ring 115 to rotate.

The chain is normalized in the normalizing ring 115, and the rotation of the normalizing ring 115 is coordinated to improve the normalizing effect. Subsequently, the normalized chain enters the quenching pool 107 for quenching, and the cooling oil carried by the chain is blown back into the quenching pool 107 through the jet gun 403.

[0030] like Figure 6 , Figure 7 As shown, the positive cleaning device includes a positive cleaning frame 201 fixedly installed in the shell 101, an entry sprocket 202 and a lower winding sprocket 203 are rotatably installed on the positive cleaning frame 201, two cleaning shafts 205 are rotatably installed on the positive cleaning frame 201, a cleaning wheel 204 is fixedly installed on the cleaning shaft 205, and a transmission belt 206 is respectively wrapped around the outside of the entry sprocket 202 and the lower winding sprocket 203 and the two cleaning shafts 205.

[0031] The chain passes through two cleaning wheels 204. When the entrance sprocket 202 and the lower sprocket 203 are driven by the chain, the two cleaning wheels 204 are driven to rotate through the transmission belt 206. Since the diameter of the cleaning shaft 205 is smaller than the diameter of the entrance sprocket 202 and the lower sprocket 203, the rotation speed of the cleaning wheel 204 is faster. In conjunction with the water spray from the water spray gun 402, the front and back sides of the chain are cleaned through the cleaning wheel 204.

[0035] The working principle of a continuous heat treatment device for a chain disclosed in the present invention is: the motor 102 rotates to drive the driving shaft 104 and the driving sprocket 105 to rotate through the driving belt 103, thereby driving the chain to move, and the chain drives the quenching sprocket 106, the upper sprocket 108, the transfer sprocket 301, the lower winding sprocket 203 and the entry sprocket 202 to rotate, and the chain passes between two cleaning wheels 204. When the entry sprocket 202 and the lower winding sprocket 203 are driven by the chain, the two cleaning wheels 204 are driven to rotate through the transmission belt 206. Since the diameter of the cleaning shaft 205 is smaller than the diameter of the entry sprocket 202 and the lower winding sprocket 203, the rotation speed of the cleaning wheel 204 is faster. In conjunction with the water spraying of the water spray gun 402, the front and back sides of the chain are cleaned through the cleaning wheel 204. The chain drives the transfer sprocket 301 to rotate, thereby driving the eccentric column 303 to rotate, and the eccentric column 303 drives the slot rod 304 to rotate around the main cleaning frame 201, thereby driving the sliding column 306 and the side cleaning brush 307 to continuously rise and fall, and the side cleaning brush 307 is used to clean both sides of the chain. The upper sprocket 108 rotates to drive the upper eccentric plate 109 to rotate, and the lower eccentric plate 111 and the worm 114 are driven to rotate through the transmission connecting rod 110, thereby driving the worm wheel 118 and the normalizing ring 115 to rotate. The chain cleaned by the front cleaning device and the side cleaning device enters the normalizing ring 115, and the gas box 112 provides gas, which is discharged from the gas outlet 117 and ignited by the igniter 116. The chain is normalized in the normalizing ring 115, and the rotation of the normalizing ring 115 is coordinated to improve the normalizing effect. Subsequently, the normalized chain enters the quenching pool 107 for quenching, and the cooling oil carried by the chain is blown back into the quenching pool 107 through the jet gun 403.
