Implementation Example

[0013] See also Figure 1-7 As shown, the technical solution provided by the present invention is based on a high-precision, high-efficiency, automated dual-alloy barrel casting automatic feeding device. This application needs to be combined with a constant temperature furnace automatic lifting barrel pushing device applied by the same applicant to understand the structure and working principle.

[0014] The present application discloses a double-alloy barrel casting process, which places 5 barrels on two material storage tilting platforms 21; through a half-moon-shaped selection feeding mechanism, it cooperates with the tilting material storage platform 21 in the design of the material storage platform 21 to realize the rapid feeding and flipping feeding of the barrel on the material storage tilting platform 21, and finally the barrel falls into the V-shaped groove 51; through the combination of gear 44, rack 45, slider 46 and slide rail 47, the barrel is pushed from the V-shaped groove 51 into the medium frequency furnace in cooperation with the reduction motor; the push rod for feeding the medium frequency furnace is used to enter the medium frequency furnace to push the barrel out and transport it to the external roller conveyor line; a push plate that can be raised and lowered is used. When the medium frequency furnace is discharging, the push plate is at the top. After the discharging is completed, the push plate descends, and cooperates with the gear 44, rack 45, slider 46 and slide rail 47 to move, so as to push the barrel into the constant temperature furnace 400.

[0015] The present application discloses an automatic barrel loading and feeding device, comprising a platform 1, on which a material storage mechanism 2, a flip loading mechanism 3, and an intermediate frequency furnace loading and unloading mechanism 4 are installed; The storage mechanism 2 includes two storage tilting platforms 21, which are combined structures. The two storage tilting platforms 21 have the same size, and the two storage tilting platforms 21 are spaced 500mm apart. The two storage tilting platforms 21 have inclined surfaces on the right side, and their lengths are both 1600mm. The two storage tilting platforms 21 have vertical plates on the left side, which are 500mm long, 1250mm wide, and 550mm high on the right side. The inclination angle is 1.73°, and the storage of 5 double alloy barrels 6 can be achieved by cooperating with the flip feeding mechanism 3. The storage mechanism 2 can store 5 double alloy barrels 6, and the size of the double alloy barrel 6 is: Ø400mm, length 3000mm. The two storage tilting platforms 21 of the present application cooperate with the flip feeding mechanism 3 to achieve the effect of storage and rapid feeding.

[0016] The flipping feeding mechanism 3 includes a half-moon rotating feeding shaft 31, a half-moon rotating feeding blade 32 and two cylinders 33, and the two cylinders 33 are both SC160×200. The two cylinders 33 are respectively installed in the two material storage tilting platforms 21, and the two cylinders 33 have output shafts, which are connected to the half-moon rotating feeding shaft 31 through a crank rocker 34. The half-moon rotating feeding blades 32 are evenly distributed on the half-moon rotating feeding shaft 31; the flipping feeding mechanism 3 separates and flips the double alloy material barrel 6 of the material storage tilting platform 21 onto the feeding guide rail. Figure 1-2 The half-moon type selection feeding mechanism shown cooperates with the inclined material storage inclined platform 21 in the design of the material storage inclined platform 21 to achieve the effect of fast feeding and flip feeding. The structure is simple and the cost is low. The flip feeding mechanism 3 can rotate the feeding, aiming to achieve a safe and accurate transportation process of the double alloy material barrel 6 between the feeding platform and the V-groove 51. Before designing the flip feeding mechanism 3, it is necessary to make a simple design for the material storage inclined platform 21 and the V-groove 51. In order to achieve a smooth downward slide of the double alloy material barrel 6 before entering the flip feeding mechanism 3, the material storage inclined platform 21 can be designed with a small angle of inclination. In this way, the double alloy material barrel 6 can slide slowly and naturally into the flip feeding mechanism 3, and the double alloy material barrel 6 is flipped to the V-groove 51 by the flip mechanism. For the design of the V-groove 51, a comprehensive design is made based on the size of the double alloy material barrel 6, the magnitude of the friction force when pushing, and other related factors.

[0017] The intermediate frequency furnace feeding and discharging mechanism 4 includes a machine base 41, a worm gear reduction motor 42, a push rod device 43, a gear 44, a rack 45, a slider 46 and a slide rail 47. The worm gear reduction motor 42 is installed in the machine base 41. The worm gear reduction motor 42 has an output shaft, and a gear 44 is installed at the end of the output shaft. The gear 44 meshes with the rack 45, and the slider 46 cooperates with the slide rail 47. The push rod device 43 is installed through the machine base 41 and the push rod device 43 cooperates with the gear 44 to mesh with the rack 45 and the slider 46 to move with the slide bar; the intermediate frequency furnace feeding and discharging mechanism 4 pushes the dual alloy material barrel 6 from the V-shaped groove 51 into the intermediate frequency furnace. The push rod device 43 cooperates with the gear 44, the rack 45, the slider 46 and the slide rail 47 to move, and the dual alloy material barrel 6 is pushed into the intermediate frequency furnace. The gear 44 rack 45 and the slider 46 rail 47 are combined with the reduction motor to push the dual alloy barrel 6, which is better than the robot gripping in terms of economy and transportation efficiency. The dual alloy barrel 6 is pushed out of the intermediate frequency furnace by the intermediate frequency furnace discharge. The push rod of the intermediate frequency furnace feed enters the intermediate frequency furnace to push the dual alloy barrel 6 out and transport it to the external roller conveyor line.

[0018] The push rod device 43 pushes the dual alloy barrel 6 into the medium frequency furnace through the V-groove 51, and after heating is completed, pushes the dual alloy barrel 6 out of the medium frequency furnace and accurately delivers it to the subsequent roller conveyor line. To achieve this goal, targeted design and manufacturing are required. Considering that the push rod needs to enter the medium frequency furnace to push the dual alloy barrel 6 out from the inside, and the length of the dual alloy barrel 6 is 3m, in order to ensure that the push rod can completely push out the dual alloy barrel 6, the length of the push rod needs to be considered. At the same time, a certain force needs to be applied to push the dual alloy barrel 6 out from the inside, so the material of the push rod needs to be selected as a material that can withstand high temperatures to ensure that the push rod will not soften and deform under high temperature conditions. In this embodiment, 40Cr, which is consistent with the material of the dual alloy barrel 6, is selected as the push rod material. When designing the length of the push rod, the clamping position of the push rod also needs to be considered. Therefore, the length of the push rod is selected as 4.5m this time to ensure that the push rod can reach the innermost part of the dual alloy barrel 6, such as and the clamping position of the push rod also has sufficient length for fixing and bearing.

[0019] The motor in this embodiment needs to have a power of more than 6.93kw. The transmission efficiency of the NMRV130 worm gear reduction motor is 0.93, so the output efficiency of the motor must be at least 7.45kw. According to the transportation speed of the dual alloy material barrel 6, the reduction ratio is selected as 25, so this design selects the NMRV130 worm gear reduction motor [RV130-E-25-7.5kW-FA1-DZ1] as the power source.

[0020] The advantages are: first, it has good rigidity, can accurately position, and can self-lock after power failure; and the system structure is simple and compact, without various complex pumps, valves, oil tanks or air sources and pipeline systems; and it has low noise, no fluid leakage, and little pollution to the environment. It is an ideal green and environmentally friendly product; due to the reducer mechanism, the system can also achieve a small drive source to transmit a large torque; it can form a closed-loop servo control system to achieve automatic control; and it uses standard original parts, which is simpler to install. Because the heat dissipation is more efficient, the lubrication cycle can be extended and the running time can be longer. Secondly, the 7.5kw motor has a large output power, high speed, simple structure, low maintenance cost and long service life.

[0021] The V-shaped bracket 5 is located at the front end of the push rod device 43 and at one side of the medium frequency furnace feeding and discharging mechanism 4. The V-shaped bracket 5 includes a V-shaped groove 51 and a support leg 52 supported on the bottom surface of the V-shaped groove 51. The V-shaped groove 51 of the V-shaped bracket 5 is 400 mm wide, 150 mm deep, 20 mm thick, and 3000 mm long. A support plate 53 is provided on the bottom surface of the support leg 52. The support is stable.

The present application is applied to the high-precision, high-efficiency, automated dual-alloy barrel casting automatic feeding device 800. The dashed line frame is the barrel automatic loading and feeding device 100 of the present application. When understanding the high-precision, high-efficiency, automated dual-alloy barrel casting automatic feeding device 800, it is necessary to combine a constant temperature furnace automatic lifting barrel pushing device applied by the same applicant.

[0023] During operation, firstly, the dual alloy material barrel 6 is transported from the slightly inclined material storage inclined platform 21 to the V-shaped groove 51 of the V-shaped bracket 5 by flipping the loading mechanism, and then the dual alloy material barrel 6 is pushed into the medium frequency furnace by the push rod device 43. After waiting for the heating to be completed, it is pushed to the roller conveyor line by the push rod for the next processing.
