Description

Technical Field

[0001] The present application relates to the technical field of carburizing processing, and in particular to a mesh belt type carburizing production equipment. Background Art

[0002] Carburizing is a process of improving the surface performance of a metal workpiece by infiltrating carbon atoms into the surface of the workpiece to change the chemical composition and organizational structure of the workpiece surface. Its core principle is based on the diffusion phenomenon of carbon atoms at high temperatures. During the carburizing process, the workpiece is placed in a medium rich in carbon atoms (such as carburizing gas, carburizing liquid or solid carburizing agent, etc.) and a specific high-temperature environment. Due to the difference in carbon concentration between the surface and the interior of the workpiece, carbon atoms will be adsorbed from the high-concentration medium to the workpiece surface, and driven by the concentration gradient, gradually diffuse into the interior of the workpiece, and finally form a carburized layer within a certain depth range on the workpiece surface, so that the carbon content on the workpiece surface is significantly higher than that in the core.

[0003] With the continuous development of modern industry, various industries have put forward higher requirements for the carburizing treatment of parts.

[0036] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limitations on the present application. On the contrary, the embodiments of the present application include all changes, modifications and equivalents that fall within the spirit and connotation of the appended claims.

[0037] The mesh belt carburizing production equipment according to an embodiment of the present application will be described below with reference to the accompanying drawings.

[0038] like Figure 1-Figure 9 As shown, the mesh belt carburizing production equipment of the embodiment of the present application may include:

[0039] Equipment frame 1, the equipment frame 1 is divided into a loading frame 101, a carburizing zone furnace body 102 and a quenching seat 103. The interior of the carburizing zone furnace body 102 is sealed when in working state. The loading frame 101 is arranged at the inlet of the carburizing zone furnace body 102, and the quenching seat 103 is arranged at the outlet of the carburizing zone furnace body 102. The carburizing zone furnace body 102 and the quenching seat 103 are in an isolated state, and an outlet partition can be arranged at the outlet position;

[0040] A gas supply system, the gas supply system is connected to the inner wall of the carburizing zone furnace body 102, and the gas supply system is used to supply carburizing gas;

[0041] The mesh belt conveyor 2 is arranged inside the furnace body 102 in the carburizing zone. The mesh belt conveyor 2 includes a motor, a reducer, an active roller, a driven roller, etc. The motor provides power, and after being decelerated by the reducer, the active roller is driven to rotate, thereby driving the mesh belt to run, ensuring that the workpiece can move at a uniform speed and in an orderly manner. The mesh belt conveyor can ensure that the workpiece can be fully carburized;

[0042] The permeation device 2 is arranged inside the furnace body 102 in the carburizing zone. The permeation device 2 includes a permeation tube 201. The inner wall of the permeation tube 201 is provided with multiple groups of air outlets 202. The outer wall of the permeation tube 201 is connected to multiple groups of gas compression devices 203. The air outlet directions of the air outlets 202 are all toward the position of the mesh belt conveyor. During the carburizing process, the pressure and flow rate of the gas at the edge are significantly improved when passing through the gas compression device 203, and then the gas is ejected through the air outlet 202 on the inner wall of the permeation tube 201 at a higher speed and pressure, directly rushing towards the workpiece on the mesh belt conveyor. Since the outlet direction of the gas outlet 202 is toward the position of the workpiece, the ejected gas can contact the surface of the workpiece quickly and in large quantities. Driven by the high-speed airflow and the concentration difference, the active carbon atoms are more efficiently adsorbed on the surface of the workpiece and diffused into the inside of the workpiece, thereby accelerating the carburizing process, which helps to obtain the required carburizing layer depth and carbon concentration in a shorter time. The gas compression device 203 can be an air compressor and a turbocharger. The air compressor compresses the gas by changing the volume of the space occupied by the gas. Like a piston compressor, the piston reciprocates in the cylinder, inhaling air when going down and compressing and exhausting the gas when going up; the screw compressor relies on a pair of intermeshing yin and yang rotors to rotate, so that the gas changes in volume between the rotors to achieve suction, compression, and discharge; the vane compressor uses the eccentric rotation of the rotor and the change in space formed by the vane and the cylinder wall to compress the gas;

[0043] The heating device is arranged inside the furnace body 102 of the carburizing zone, and adopts electric heating or gas heating, and is provided with heating wires, such as resistance wires, radiation tubes, etc. The heating element generates heat after being energized or gas is introduced, so that the temperature inside the furnace is raised to the high temperature range required for carburizing, generally around 850℃-950℃, to preheat the incoming workpiece and create suitable temperature conditions for the subsequent carburizing reaction.

[0044] Equipped with precise temperature control system, which consists of thermocouple, PID regulator, thyristor, etc. The thermocouple monitors the temperature in real time and feeds back to the PID regulator. The regulator controls the thyristor according to the set temperature to adjust the power of the heating element to ensure stable and uniform temperature.

[0045] A control system is used to control the gas supply system, the permeation device 2 and the heating device.

[0046] Furthermore, the mesh belt carburizing production equipment further comprises:

[0047] In one embodiment of the present application, Figure 2-Figure 5 As shown, the permeation tube 201 is in a threaded shape, the mesh belt conveyor 2 is arranged on the inner ring of the permeation tube 201, the permeation device 2 also includes two groups of ring frames 204, the inner wall of the carburizing zone furnace body 102 is provided with two groups of ring bearings 205, the ring frame 204 is rotatably connected to the inner wall of the carburizing zone furnace body 102 through the ring bearings 205, the permeation tube 201 is fixed between the two groups of ring frames 204, wherein the outer wall of one group of ring frames 204 is fixed with an external gear 206, the external gear 206 is meshedly connected with a pinion 207, and the pinion 207 rotates on the inner wall of the device frame 1 Two groups of mutually meshing steering gears 208 are connected, and an incomplete gear 209 is connected to the center of the steering gear 208. The two groups of incomplete gears 209 are connected to the pinion 207. When one group of incomplete gears 209 is meshed with the pinion 207, the other group of incomplete gears 209 is not meshed with the pinion 207. A steering motor 210 is fixed inside the carburizing zone furnace body 102, and the output end of the steering motor 210 is connected to a group of steering gears 208. The number of teeth of the incomplete gear 209 is preferably about one third of the total number of teeth of the complete gears.

[0048] When the steering motor 210 is driven, the steering motor 210 drives a set of steering gears 208 to rotate. Since the two sets of steering gears 208 are meshed and connected, the rotation directions of the two sets of steering gears 208 are opposite, and the two sets of incomplete gears 209 connected to the steering gears 208 rotate in opposite directions, thereby driving the ring frame 204 to rotate left and right in a gap, so that the cyclone generated by the threaded permeability enhancement tube 201 can change back and forth, and in the process of left and right rotation, the air inlet position of the gas compression device 203 also changes accordingly, and the air inlet position is adjusted to a gas position with higher concentration, and moves to the next position after the pressurization of one position is completed.

[0049] The flow path of the threaded carburizing tube 201 becomes more complex and tortuous. The threaded carburizing tube 201 allows the carburizing gas to form a cyclone, further increasing the probability of interaction between the active carbon atoms in the gas and the workpiece surface, which helps to achieve a more uniform and sufficient carburizing process.

[0050] In one embodiment of the present application, Figure 1 , Figure 6 As shown, it also includes a feed cylinder 301, the feed port of the loading frame 101 is slidably connected with a feed plate 302, the side wall of the feed port of the carburizing zone furnace body 102 is fixed with the feed cylinder 301, the output end of the feed cylinder 301 is connected to one end of the feed plate 302, and a sealing strip is provided at the contact between the feed plate 302 and the feed port of the carburizing zone furnace body 102, and the feed cylinder 301 can drive the feed plate to open and close.

[0051] In one embodiment of the present application, Figure 7 As shown, there are two groups of mesh belt conveyors 2, one group of mesh belt conveyors is arranged below the other group of mesh belt conveyors 2, the inlet of one group of mesh belt conveyors is arranged at the outlet position of the other group of mesh belt conveyors, and two groups of mesh belt conveyors 2 are arranged. When the processed workpiece is transmitted from one group of mesh belt conveyors 2 to another group of mesh belt conveyors 2, the processed workpiece can be turned over to expose the contact area between the mesh belt conveyor 2 and the workpiece.

[0052] In one embodiment of the present application, Figure 1 As shown, a feeding conveyor belt 4 is arranged on the inner wall of the feeding frame 101, and a feeding end of the feeding conveyor belt 4 is arranged at the feeding port of the furnace body.

[0053] In one embodiment of the present application, Figure 1 , Fig. 9 As shown, the quenching seat 103 is provided with a discharge conveyor belt 5, and a quenching liquid is provided inside the quenching seat 103, and the liquid level of the quenching liquid is higher than the discharge port. The discharge conveyor belt 5 is tiltedly arranged inside the quenching seat 103. The workpiece after carburizing treatment needs to be quenched and cooled in time to obtain the required structure and performance. The workpiece moves to the discharge conveyor belt 5 with the mesh belt, and the quenching liquid such as oil, water or salt water is filled in the quenching seat 103 tank. After the workpiece enters the quenching tank, the quenching medium quickly absorbs the heat on the surface of the workpiece, so that the workpiece is quickly cooled, thereby achieving quenching.

[0054] The quenching seat 103 is sealed and connected to the equipment, the quenching liquid is higher than the quenching seat 103 to complete the sealing of the discharge port, and the discharge conveyor belt 5 moves the workpiece out.

[0055] In one embodiment of the present application, Figure 8As shown, a slope conveyor belt 3 is arranged between the discharge conveyor belt 5 and the mesh belt conveyor device 2, and the slope conveyor belt 3 can be used for buffering during the movement of the workpiece.

[0056] In one embodiment of the present application, the gas supply system includes a gas supply pipeline, a gas valve, a gas probe and a pressure sensor. The gas probe and the pressure sensor are used to monitor the carbon potential of the internal atmosphere, and adjust parameters such as the gas flow rate according to the monitoring results to ensure the stability of the carburizing atmosphere so that the workpiece obtains a uniform and satisfactory carburizing layer. The safety protection device, the pressure sensor and the safety valve are used in conjunction. The pressure sensor monitors the gas pressure in the pipeline in real time. When the pressure exceeds the set value, the safety valve will automatically open to release excess gas to prevent safety accidents such as rupture or explosion of the pipeline or equipment due to excessive pressure.

[0057] The gas supply system also includes a gas leak detection device: installed in key locations of gas delivery pipelines and equipment to detect gas leaks. Once a gas leak is detected, an alarm signal will be issued immediately and the gas supply can be automatically cut off to ensure personnel safety and prevent dangerous situations such as fire and explosion.

[0058] The gas supply system also includes a flashback arrester: when using flammable gases, it can prevent the flame from flowing back into the gas source or gas pipeline to avoid causing an explosion and ensure the safe operation of the gas supply system.

[0059] In one embodiment of the present application, the heating device includes a thermocouple, a PID regulator and a heating wire. The thermocouple monitors the temperature in real time and feeds back to the PID regulator. The regulator controls the thyristor to adjust the power of the heating wire according to the set temperature to ensure stable and uniform temperature.

[0060] It should be noted that in the above-mentioned embodiment, the operator needs to set the corresponding heating parameters in the control system according to the carburizing process requirements, mainly including the target heating temperature (generally the heating temperature of the carburizing zone is set at about 850℃-950℃), the heating rate and the heating time, etc. The setting of these parameters is crucial for the subsequent accurate realization of the carburizing process and the acquisition of the ideal carburizing quality of the workpiece. Different workpiece materials, sizes and expected carburizing layer depths will affect the specific values ​​of these parameters. For example, for workpieces of smaller size and materials that are easier to carburize, the heating rate can be appropriately faster, while for large or special material workpieces, a slower heating process may be required to avoid deformation, cracking and other problems of the workpiece due to excessive thermal stress.

[0061] Specifically, the workpiece comes to the carburizing furnace from the previous processing area, and the gas supply system supplies carburizing gas to the workpiece to enter the furnace, and the heating device heats it. When the gas at the edge passes through the gas compression device 203, the pressure and flow rate are significantly improved, and then it is ejected through the gas outlet 202 on the inner wall of the permeation tube 201 at a higher speed and pressure, and directly rushes to the workpiece located on the mesh belt conveyor. Since the gas outlet direction of the gas outlet 202 is toward the position of the workpiece, the ejected gas can quickly and in large quantities contact the surface of the workpiece, and the active carbon atoms are more efficiently adsorbed on the surface of the workpiece under the drive of the high-speed airflow and the concentration difference, and diffuse into the inside of the workpiece. The gear group drives the permeation device 2 to move, so that the cyclone generated by the threaded permeation tube 201 can change back and forth, and in the process of left and right rotation, the air inlet position of the gas compression device 203 also changes accordingly, and the air inlet position is adjusted to a gas position with a higher concentration, and moves to the next position after the pressurization of one position is completed.

[0062] In summary, the mesh-belt carburizing production equipment and the carburizing equipment of the embodiment of the present application enable the ejected gas to contact the workpiece surface quickly and in large quantities, and the active carbon atoms are more efficiently adsorbed on the workpiece surface and diffused into the interior of the workpiece under the drive of the high-speed airflow and the concentration difference. The flow path of the threaded carburizing tube 201 becomes more complex and tortuous. The threaded carburizing tube 201 allows the carburizing gas to form a cyclone, further increasing the probability of interaction between the active carbon atoms in the gas and the workpiece surface, which helps to achieve a more uniform and sufficient carburizing process.
