Description

Technical Field

[0001] The present invention relates to the technical field of forging processing equipment, and particularly to an electromagnetic intelligent control precision forging heating composite machine. Background Art

[0002] The heating methods adopted in the traditional industrial red punching and forging industry are divided into three types, namely solid medium heating, liquid medium heating, and gaseous medium heating; and according to the trend of industry development and the strengthening of the state's supervision, incentives, and support for enterprises' cleaner production, more and more red punching and forging enterprises have begun to gradually introduce electromagnetic heating production process technology.

[0003] The emerging electromagnetic heating technology greatly makes up for the process defects existing in the traditional heating methods, and at the same time enables production enterprises to meet the implementation standards advocated by the government in terms of waste gas emissions, industrial safety production, energy conservation and environmental protection. For example, when using the traditional heating method to heat products, the heating principle of the workpieces is contact air heat transfer, and only the relative temperature in the workpiece heating container can be controlled, and the temperature of the workpiece itself cannot be directly, quickly, and accurately controlled. Under the condition of relative time, the temperature difference between the core and the surface of the workpiece is very large, and the quality of the workpiece cannot be effectively guaranteed. Especially when heating workpieces made of materials with lower melting points, the defects are more obvious and prominent; on the other hand, the advanced foreign unmanned or less manned automated manufacturing technology is constantly encroaching on domestic traditional manufacturing enterprises, and the profit space of the industry is constantly being compressed. Especially with the loss of the domestic demographic dividend advantage year by year, traditional red punching and forging enterprises are facing great difficulties and urgent transformation and upgrading.

[0004] In view of the above technical defects, a solution is now proposed. Summary of the Invention

[0035] A number of load-bearing wheels are connected to the bottom surface of the integrated steel structure support 1. Fixed-point adjustable feet are provided on the outer surfaces of the load-bearing wheels, forming a movable mechanism through the load-bearing wheels.

[0036] The working principle is as follows: After pouring the base material to be forged and heated into the bucket-shaped bin, the PLC manual / automatic operation interface mode is turned on. The heavy-duty cylinder 35 will communicate with the full-material induction contact piece on the high-temperature resistant servo feeding module 4 in real time according to the beat parameters set by the system. When no trigger signal is detected within two consecutive beat cycles, the heavy-duty cylinder 35 will automatically start. The multi-stage lifting feeding plate 38 will lift the base material in the bin to the high-temperature resistant servo feeding module 4 under the reciprocating action of the heavy-duty cylinder 35 for feeding. On the contrary, when a trigger signal is detected within two consecutive beat cycles, the heavy-duty cylinder 35 will automatically recognize that the high-temperature resistant servo feeding module 4 is full and stop automatic feeding, thus reducing the noise and ineffective energy loss of air generated during automatic feeding.

[0037] The chain-type automatic conveying system is formed by combining the anti-stacking and overflow blocking mechanism, the intermittent combined pressing mechanism 8, the dual-channel lateral pushing mechanism 7, the anti-static bridge guiding mechanism 6 and the high-temperature resistant servo pushing module 4, which can be compatible with smooth and unimpeded conveying of substrates of different sizes and automatically and standardizedly arrange the substrates in the process. The chain conveys the substrates in the feeding direction under the unidirectional rotation of the servo motor 48. The anti-stacking and overflow blocking mechanism intervenes to block the substrates that exceed the set height and width, and sends the induction signal to the overflow cylinder to push the substrates that are not arranged in the set shape to the overflow port and fall back to the silo.

[0038] The remaining substrates arranged as required will continue to be conveyed to the intermittent combined pressing mechanism 8. The intermittent combined pressing mechanism 8 selects a suitable pressing cylinder position according to the length of the substrate, and only allows one substrate to pass through the position at a time. The substrate contacts the terminal sensing contact piece and triggers a signal to the PLC system. The remaining substrates on the chain belt will be automatically blocked and wait for the next beat to be conveyed. After the terminal on-off sensing contact piece receives the substrate touch signal, the PLC system will simultaneously give multiple communication instructions, including stopping the chain to continue feeding, large and small induction heating channel selection and associated delayed lateral pushing; after the dual-channel lateral pushing mechanism 7 receives the material signal, it will push the substrate laterally to the direction of the bridge plate 64 according to the communication option instruction given by the PLC system, and the substrate will roll to the anti-static bridge guide mechanism 6 corresponding to the entrance of the intelligent induction dual-channel heating bin 5 under the action of the lateral driving force;

[0039] The high temperature resistant servo push module 4 can flexibly modify and adjust the substrate feeding and discharging stroke and output torque protection according to the process parameters set in the PLC system, realizing the fully automatic one-key emptying furnace technology without tailing in the magnetic induction coil heating channel, meeting the functional requirements of the equipment being ready to use, energy saving and cost reduction, and no substrate waste. When the dual-channel lateral push mechanism 7 is in place, the cylinder magnetic sensor will give a communication instruction to the PLC system, and the servo motor 48 will push the substrate smoothly into the intelligent dual-channel induction heating bin according to the parameters set in the PLC system interface;

[0040] Different processing parameters are preset according to the types of processable substrates. The processing parameters include heating power, heating frequency, substrate heating temperature, workpiece material, and workpiece specifications, and are stored in the storage module. Before processing, the corresponding heating power, heating frequency, and substrate heating temperature are selected according to the workpiece material and workpiece specifications of the substrate to be processed. The high-temperature servo pushing module sends the substrate to the 316L stainless steel guide rail 58 in the quartz tube of the spiral induction coil 56 according to the parameters set by the PLC system. The substrate is pushed forward by the rear stock in turn according to the beat requirements and the set arrangement method. After the substrate enters the safe R-point heating range set by the PLC system, the built-in intermediate-frequency power supply will start the through-type magnetic induction heating of the substrate according to the output parameters given by the PLC system. The external dual-color infrared sensor is started synchronously and timely collects and feeds back the actual temperature of the substrate after heating. The PLC system timely corrects the power output of the power supply according to the data collected and fed back by the dual-color infrared temperature sensor 53, so that the heated substrate is maintained within a relatively reasonable set temperature difference range. The substrate is pushed to the discharge port after heating according to the beat time set by the system;

[0041] The intelligent induction double-channel heating chamber 5 performs reasonable power matching output on the heated substrate in the chamber according to the selected channel and output parameter formula given by the PLC system, and makes it quickly and evenly penetrate heat under the premise of precise temperature control. It not only eliminates the quality defects of forging products caused by unstable heating temperature control of the substrate in the traditional hot forging process, but also improves the heating production efficiency. The built-in double-channel structure design makes the equipment more compatible. Users can reasonably select a more suitable heating channel according to the product shape size, breaking through the limitations of the traditional single-channel customized heating design, enabling the utilization of effective energy conversion. The magnetic lines of force will penetrate the high-temperature transparent quartz tube 54 and generate countless small eddies in the metal substrate body in the tube, causing the metal ferromagnetic substrate itself to spasm and heat evenly. The basically enclosed high-temperature transparent quartz tube 54 on the periphery can reduce a large amount of heat dissipation, further reducing and lowering the waste of ineffective energy consumption, and greatly reducing the manufacturing cost of the enterprise;

[0042] When the heated substrate is pushed to the outlet of the intelligent induction double-channel heating chamber 5, the system control program will give a signal to control the telescopic cylinder to complete the high and low gear commutation switch according to the interval standard set by the PLC system and referring to the actual substrate heating temperature fed back by the external dual-color infrared temperature sensor 53. The products within the set interval temperature slide down to the blanking tray 98 through the double-channel cross-over plate 64, while the over-temperature or low-temperature products will be switched to the low channel and dropped into the secondary heating recovery hopper. The PLC automatically screens according to the data collected and fed back by the dual-color infrared temperature sensor 53. The automatic screening module 9 can effectively prevent the substrates with large temperature differences after heating from flowing into the forging and forming process, avoiding and reducing the risk of forging die damage and billet scrapping after forging and forming.

[0043] Example 2:

[0044] As shown Figure 8 in the figure, the electromagnetic intelligent control precision forging heating composite machine includes an integrated steel structure bracket 1, a machine shell 2, and an integrated control system. The integrated control system includes a PLC system, a temperature feedback module, a parameter output module, a temperature review module, and a processing analysis module;

[0045] The temperature feedback module is used to obtain the actual substrate heating temperature fed back by the dual-color infrared temperature sensor 53, obtain the heating parameters set by the PLC system, obtain the preset temperature of the substrate according to the heating parameters, calculate the temperature difference between the preset temperature of the substrate and the actual substrate heating temperature, and send the temperature difference to the parameter output module;

[0046] The parameter output module obtains and processes the temperature difference, preset a temperature difference threshold. If the temperature difference is greater than the temperature difference threshold, calculate the parameter adjustment value according to the temperature difference, and send the parameter adjustment value to the PLC system;

[0047] The temperature review module is used to obtain the actual substrate heating temperature fed back by the dual-color infrared temperature sensor 53, and preset a temperature review range (Tmin, Tmax). Judge the actual substrate temperature according to the preset temperature review range. If the actual temperature is greater than or equal to Tmin and less than or equal to Tmax, generate a review qualified signal. If the actual temperature is less than Tmin or greater than Tmax, generate a review unqualified signal, and send the review qualified signal and the review unqualified signal to the PLC system and the processing analysis module;

[0048] The processing analysis module is used to receive the review qualified signal and the review unqualified signal, record the frequencies of the review qualified signal and the review unqualified signal, calculate the product abnormality coefficient according to the frequencies, and judge the product abnormality coefficient according to the preset abnormality threshold to generate a maintenance signal and send it to the PLC system.

[0049] The specific process of generating the maintenance signal is as follows:

[0050] S101. Obtain the preset product processing cycle. At the start time of the processing cycle, obtain the frequency F1 of the review qualified signal and the frequency F2 of the review unqualified signal, and calculate the product abnormality coefficient Wi according to the following formula: where e1 and e2 are respectively preset proportionality coefficients;

[0051] S102. Obtain the preset abnormality threshold Wm. If the product abnormality coefficient Wi is greater than or equal to the abnormality threshold Wm, it means that the defective rate of the heating composite machine is too high at this time. Generate a maintenance signal and send it to the PLC system, and display it through the PLC system to remind the staff to repair the heating composite machine;

[0052] If the product abnormality coefficient Wi is less than the abnormality threshold Wm, no signal is generated.

[0053] The settings of the size of the interval and the threshold are for the convenience of comparison. Regarding the size of the threshold, it depends on the amount of sample data and the number of base values set by those skilled in the art for each set of sample data; as long as the proportional relationship between the parameters and the quantized values is not affected.

[0054] The above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes should be covered within the protection scope of the present invention.
