one,Semi-shaft induction heating furnaceHeating material and temperature:

       Semi-shaft induction heating furnaceThe materials for heating axles are generally 40Cr, 42CrMo, 42CrMoH, and 40MnBH. The heating temperature requirements are: 40Cr heating range 1000~1200℃, 42CrMo, 42CrMoH and 40MnBH heating range 1000~1150℃.

two,Semi-shaft induction heating furnaceHeating principle:

        Semi-shaft induction heating furnaceUsually consists of induction heater, control cabinet and cooling system. The induction heater is mainly composed of a power supply, an intermediate frequency converter and a heating coil. It can convert electrical energy into an intermediate frequency current, generate a magnetic field through the heating coil, and generate eddy currents on the surface of the half shaft to achieve the heating effect. The control cabinet is mainly used to control the heating temperature and time of the heating furnace, and to protect the normal operation of the half-shaft heating furnace. The cooling system is mainly used to controlSemi-shaft induction heating furnacetemperature to prevent overheating and damage.

        Semi-shaft induction heating furnaceUsing induction electric heating, the billet is placed into the induction coil. Under the action of the induced electromotive force of the alternating current, a strong eddy current is formed on the surface of the billet, so that the electrical energy inside the billet is directly converted into heat energy.

three,Semi-shaft induction heating furnaceProduction line composition:

Automobile half-shaft automationSemi-shaft induction heating furnaceThe forging production line is mainly used for the automated production of forging and forming of automobile half shafts. The equipment of this production line mainly includes: a fully automatic metal disc sawing machine, a paving and storage table, three sets of vertical (or inclined) medium frequency heating furnaces, three six-axis joint robots, and two descaling and cleaning machines. , a double-action single-station upsetting machine, a double-action double-station upsetting machine, a horizontal swing rolling press, three sets of graphite emulsion automatic spray machines, palletizing truss robots and palletizing baskets, It consists of a highly integrated system of safety protection fence, mold and mold quick-change mechanism, and a set of bus control equipment.

Four,Semi-shaft induction heating furnaceProduction line working process description:

Manually hoist the bundles of bars into the fully automatic metal disc sawing machine using a crane, and automatically unload and sort the materials to the paving and storage table; the paving and storage table has transportation and positioning devices to facilitate the grabbing of the 1# robot. Grab the bar and rotate it vertically to place it on the splineSemi-shaft induction heating furnacemedium; after reaching the temperature, the 1# robot grabs and puts it into the descaling and cleaning machine 1# to remove the oxide scale, and then places the workpiece into the double-action single-station upsetting machine to start pre-heading splines; after the pre-heading splines are completed, 2 #The robot grabs the workpiece, rotates it, turns around and places it onSemi-shaft induction heating furnaceMedium heating, after reaching the temperature, the 2# robot grabs the workpiece and places it in the double-action dual-station upsetting machine to start pre-heading the half shaft (mushroom head); after the pre-heading half shaft is completed, the 3# robot grabs the workpiece and places it in the removal machine. The scale cleaning machine #2 removes the oxide scale, and then places the workpiece on the horizontal swing rolling press to start rolling the flange; after the flange rolling is completed, the robot #3 grabs the workpiece and places it on the palletizing table. The palletizing truss robot and the palletizing basket automatically complete the palletizing of the workpieces; finally, the palletizing basket is manually removed. The entire automation work is completed (the action sequence of different workpieces can be adjusted by itself).

Semi-automaticSemi-shaft induction heating furnaceThe heating forging process currently mostly adopts the monotonous method of heating-pre-heading-rolling, with manual loading and unloading.。A production line using automated servo CNC forged half shafts.

five,Semi-shaft induction heating furnacetemperature control:

          Semi-shaft induction heating furnaceDuring the forging heating process, if the heating temperature of the half shaft is too high, overburning will occur. If the material is overburned, the raw material will be scrapped, resulting in a huge waste of resources. Forging heating is a key process. To prevent the half shaft from over-burning, the heating temperature must be controlled.

          Semi-shaft induction heating furnaceInduction heating and infrared thermometer temperature measurement methods are commonly used, heating according to the beat, and measuring the temperature after heating for a time (beat). This kind of real-time temperature detection during the half-shaft heating process enables temperature control. When the half-shaft is heated to the temperature range required by the process, the material will be automatically discharged to avoid over-burning of the half-shaft and reduce the waste products caused by human factors. This is An effective method to improve the quality of half shaft products.
