[0035] In the material selection step, the materials are stored in a designated area outside the device body 1 and manually transported to the vicinity of the device; in the step of cutting into a circular blank, a cutting device is separately provided from the device body 1, and the cut circular blank is transferred to the feeding tray by manual or auxiliary tool.

[0036] In the step of entering the blank into the inlet of the stamping machine, a guide device is provided at the inlet, which is connected with the device body 1 and used for guiding the blank to accurately enter the stamping position; in the step of cooling after stamping and sending into the material receiving box 41 with a buffer assembly, the cooling device is connected with the zero-degree cooling discharge port 26 of the device body 1, and the head falls into the material receiving box 41 through the discharge port after cooling.

[0037] The process is as follows: selecting materials; heating the blank to an appropriate temperature; cutting into a circular blank; feeding the feeding tray; the blank mechanical arm suction cup is placed on the lower die of the stamping machine after the blank enters the inlet of the stamping machine and is coated with lubricant (such as graphite, oil) at the lubricating mechanism 3; the upper die goes down to apply pressure, so that the blank adheres to the mold cavity; the cutting machine cuts off the excess edge and retains the designed size; the inner surface of the head is polished; the blank is cooled and sent into the material receiving box 41 with a buffer assembly after stamping.

[0038] A manufacturing method of an elliptical head, comprising a device body 1, a manufacturing mechanism 2, a lubricating mechanism 3 and a material receiving and buffering mechanism 4 arranged on the device body 1. The manufacturing mechanism 2 comprises a conveying box 21, a suction cup conveying device 22, a stamping assembly 23, a cutting assembly 24, a polishing assembly 25 and a zero-degree cooling discharge port 26; the lubricating mechanism 3 comprises a support plate 31, an oil tank 32, an oil dropping port 33, a lubricant storage 34 and an absorbent applicator 35; and the material receiving and buffering mechanism 4 comprises a material receiving box 41, a drawer 42, a sliding block 43 and an air bag 44.

[0039] Material selection and heating operation The operator uses the crane to hoist the Q345R steel plate from the raw material storage area outside the device body 1 to the vicinity of the heating furnace.

[0040] Put the steel plate into the heating furnace, set the heating temperature to 1000℃ (within the range of 900-1200℃), and start the heating furnace for heating. During the heating process, the temperature is monitored in real time by the temperature sensor inside the heating furnace to ensure that the temperature is stable around the set value. The heating time is controlled within an appropriate range according to factors such as the thickness of the steel plate, generally about 30-60 minutes, to improve the plasticity of the material.

[0041] Cutting and feeding operation After heating is completed, use a forklift to transfer the heated steel plate to the external cutting equipment. The cutting equipment uses a plasma cutting machine. The operator measures and marks the steel plate according to the design size of the elliptical head, then starts the plasma cutting machine, and cuts the steel plate into a circular blank according to the marked lines.

[0042] After cutting is completed, the operator uses a special clamp to pick up the circular blank and place it on the feeding tray. The feeding tray is driven by a motor and slowly transports the blank along the preset track to the conveying box 21 of the device main body 1.

[0043] Blank conveying and lubrication operation When the feeding tray sends the blank to the vicinity of the conveying box 21, the suction cup conveyor 22 on the conveying box 21 starts. The suction cup is extended under the action of the air cylinder and approaches the surface of the blank, grabbing the blank by vacuum adsorption.

[0044] The suction cup conveyor 22 stably sends the blank into the device main body 1 through the input port of the punching machine. Before the blank enters the punching area, the lubrication mechanism 3 starts to work. The oil tank 32 stores graphite machine oil mixed lubricant. By controlling the valve of the oil dripping port 33, the lubricant flows into the lubricant warehouse 34 at an appropriate flow rate. The lubricant smearing part 35 is made of sponge material. After absorbing the lubricant from the lubricant warehouse 34, it moves to the surface of the blank under the action of the electric push rod, uniformly smears the lubricant, to reduce the friction between the blank and the mold in the subsequent punching process, and prevent the blank from cracking.

[0045] Punching forming operation After the blank is smeared with lubricant, the blank mechanical arm suction cup (not explicitly labeled in the figure, but belongs to the regular part of the device) moves to accurately place the blank on the lower die of the punching machine.

[0046] The upper die of the punching assembly 23 slowly descends under the drive of the hydraulic cylinder, applying pressure to the blank. During the punching process, the pressure sensor, speed sensor, and temperature sensor installed on the punching assembly 23 monitor the punching speed, pressure, and temperature in real time, and feed the data back to the control system. The control system automatically adjusts the pressure and speed of the hydraulic cylinder according to the preset parameter range, ensuring that the blank fits the mold cavity under appropriate conditions, avoiding excessive deformation or cracking.

[0047] Cutting and polishing operations After the stamping is completed, the cutting assembly 24 is started. The cutting assembly 24 adopts a laser cutting machine, which cuts the stamped head according to the preset program, accurately cuts off the excess edge, and retains the designed size.

[0048] Then, the polishing assembly 25 starts to work. The polishing assembly 25 is equipped with a rotating grinding wheel, which rotates at high speed under the drive of the motor to polish the inner surface of the head, eliminate stress concentration points, and make the inner surface of the head smooth and flat.

[0049] Cooling and material collection operations The polished head is cooled through the subzero cooling discharge port 26. The subzero cooling discharge port 26 is connected with a cooling device, which adopts a liquid nitrogen cooling method to quickly cool the head to room temperature.

[0050] The cooled head falls into the material collection box 41 of the material collection buffer mechanism 4. The air bag 44 in the material collection box 41 is made of rubber material and is filled with air. When the head falls down, the air bag 44 is deformed by extrusion, which plays a buffering role to prevent the head from being damaged. When the number of heads accumulated in the material collection box 41 reaches a certain number, the operator pulls the handle on the drawer 42 to make the sliding block 43 slide along the sliding rail, and then the drawer 42 is pulled out, and then the head is taken out for subsequent inspection and packaging operations.

[0051] Working principle: Material selection and heating: first, select Q345R material from the designated area outside the device main body 1, heat it to an appropriate temperature of about 900-1200℃, to improve the plasticity of the material.

[0052] Cutting and feeding: use external cutting equipment to cut the heated material into a circular blank, and then transfer the circular blank to the feeding tray by manual or auxiliary tools. The feeding tray delivers the blank to the delivery box 21.

[0053] Blank conveying and lubrication: the suction cup conveyor 22 on the delivery box 21 acts, the suction cup extends to grab the blank, and the blank is sent into the device main body 1 through the delivery inlet of the punching machine. Before the blank enters the punching area, the lubrication mechanism 3 starts to work. The lubricant in the oil tank 32 flows into the lubricant bin 34 through the oil dropping port 33, and the lubricant is absorbed by the lubricant applicator 35 from the lubricant bin 34 and applied to the surface of the blank to reduce friction and prevent the blank from cracking during subsequent stamping.

[0054] Punching forming: the blank is placed on the lower die of the punching machine by the blank mechanical arm suction cup, and the upper die of the punching assembly 23 applies pressure to make the blank fit the mold cavity. The stamping speed, pressure and temperature are monitored and controlled in real time to avoid excessive deformation or cracking of the blank.

[0055] Cutting and polishing: after the stamping, cutting assembly 24 is actuated to cut off the excess edge and keep the designed size. Then, polishing assembly 25 is actuated to polish the inner surface of the head to eliminate the stress concentration points.

[0056] Cooling and collecting: the polished head is cooled by cooling and discharging port 26 at zero below, and then falls into the collecting box 41 of the collecting buffer mechanism 4. The air bag 44 in the collecting box 41 buffers the falling head to prevent damage. When the number of heads accumulated in the collecting box 41 reaches a certain amount, the drawer 42 can be pulled out through the sliding block 43 to take out the heads.

[0057] Through the above working process, the device and method can efficiently and stably complete the manufacture of the elliptical head, ensuring the quality and production efficiency of the head.

[0058] The above are only exemplary embodiments of the present disclosure, and cannot limit the scope of the present disclosure. That is, any equivalent changes and modifications made in accordance with the teachings of the present disclosure are still within the scope of the present disclosure. Other embodiments of the present disclosure will be readily apparent to those skilled in the art upon considering the specification and practicing the true principles of the present disclosure.

The specification and examples are only considered as exemplary, and the scope and spirit of the present disclosure are defined by the claims.
