A swing frame is rotatably connected to the main frame, and a cylinder is mounted on the top of the swing frame. The piston rod of the cylinder is connected to a connector, and a spinning roller is rotatably connected to the connector. A mounting frame is connected to the front of the connector, and a liquid storage box is connected to the front of the mounting frame. A removable cover is provided on the top of the liquid storage box, and an oil supply pipe is connected to the bottom of the liquid storage box. One end of the oil supply pipe is connected to a nozzle, and the other end of the oil supply pipe passes through the liquid storage box and is equipped with an oil pump.

This achieves liquid isolation at the friction interface, thereby completely eliminating direct metal-to-metal contact between the roller and the steel plate, achieving bidirectional protection.

Description

Technical Field

[0001] This utility model relates to the field of metal product processing equipment, and in particular to a forming machine for producing woks. Background Technology

[0002] As a basic cooking utensil, the core performance of a wok lies in the quality of its forming and the integrity of the materials. Traditional woks are made from round metal sheets, which need to be plastically deformed into a curved body. This process requires the curved surface of the wok to be uniform and smooth to ensure heating efficiency and food flowability; at the same time, it is necessary to maintain the stability of the metal grain structure to avoid localized weaknesses or deformation defects caused by excessive stress, which directly affect the product's thermal conductivity, structural strength, and service life.

[0003] Current mainstream production employs a rotary extrusion molding process: a circular steel plate is placed at the center of a mold and its center position is fixed. A hydraulically driven extrusion roller rotates at high speed from the center outwards along a spiral trajectory, extruding the steel plate. Under radial pressure, the steel plate continuously conforms to the curved surface of the mold, gradually bending into a pot-shaped configuration. During this process, the contact surface between the steel plate and the extruded cake generates instantaneous high temperatures due to intense plastic deformation. Existing technologies primarily achieve thermal management through external spray cooling water.

[0004] However, high-speed rotation and extrusion cause continuous and intense friction between the steel plate and the spinning roller. Spray cooling can only control the surface temperature and cannot eliminate the accumulation of microscopic wear at the contact interface. Under long-term high-load friction, the spinning roller will undergo progressive wear, and its working surface accuracy will decrease accordingly, causing two problems: uneven contact between the worn spinning roller and the steel plate will cause scratches, ripples or thickness deviations on the surface of the formed pot, significantly reducing the appearance quality and smoothness; and frequent replacement of the spinning roller will increase production costs and downtime.

[0022] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0023] This embodiment mainly describes the structure of the wok production equipment, as follows:

[0024] A forming machine for producing woks, such as Figures 1-4As shown, the assembly includes a main frame 1, a swing frame 2, a mold 3, a spinning wheel 4, a mounting frame 5, a liquid storage box 6, a cover plate 7, an oil supply pipe 8, a nozzle 9, an oil pump 10, a cylinder 11, a connector 12, and a collection assembly. The main frame 1 is equipped with a drive assembly. The mold 3 is rotatably connected to the middle of the main frame 1. The drive assembly and the mold 3 together clamp and rotate the steel plate. The swing frame 2 is rotatably connected to the main frame 1. A cylinder 11 is mounted on the top of the swing frame 2. The piston rod of the cylinder 11 is connected to the connector 12. The connector 12 is rotatably connected to the spinning wheel 4. The front of the connector 12 is connected to the mounting bracket 5, and the front of the mounting bracket 5 is connected to the liquid storage box 6. The top of the liquid storage box 6 is equipped with a removable cover plate 7, and the bottom of the liquid storage box 6 is connected to the oil supply pipe 8. One end of the oil supply pipe 8 is connected to the nozzle 9, which faces the lower end of the spinning wheel 4. The other end of the oil supply pipe 8 passes through the liquid storage box 6 and is equipped with an oil pump 10. The oil film generated by the spray completely eliminates the wear of the spinning wheel 4, and the squeezing and lubrication actions are synchronized in milliseconds, avoiding surface scratches caused by dry friction. A collection component for collecting liquid is provided in the middle of the main frame 1.

[0025] like Figure 1 , Figure 3 and Figure 4 As shown, the collection assembly includes a fixed plate 13, a guide rod 14, a return spring 15, a liquid guide plate 16, and a collection box 17. The fixed plate 13 is connected to the main frame 1. The guide rod 14 is slidably connected inside the fixed plate 13. The top of all the guide rods 14 is connected to the liquid guide plate 16. The diameter of the liquid guide plate 16 is larger than the diameter of the steel plate being processed. The liquid guide plate 16 is located at the lower end of the mold 3. The inner ring of the liquid guide plate 16 is rotatably connected to the mold 3. The guide rod 14 is fitted with a return spring 15. The top of the return spring 15 is connected to the liquid guide plate 16, and the bottom of the return spring 15 is connected to the fixed plate 13. The liquid guide plate 16 has an opening. The collection box 17 is slidably connected to the bottom of the liquid guide plate 16 and passes through the fixed plate 13.

[0026] like Figure 4 As shown, it also includes a scraper 18, which is slidably connected inside the liquid guide plate 16. The scraper 18 rotates around the central axis of the liquid guide plate 16 to remove residual oil.

[0027] like Figure 4 As shown, it also includes a filter screen 19, which is connected to the opening of the liquid guide plate 16.

[0028] like Figure 4 As shown, it also includes a handle 20, which is connected to the front of the collection box 17.

[0029] like Figure 2 and Figure 3 As shown, it also includes an observation window 21. The front side panel of the liquid storage box 6 is provided with an observation window 21 made of transparent material, and the front side panel of the collection box 17 is provided with an observation window 21 made of transparent material.

[0030] like Figure 2 As shown, it also includes a pull rope 22. The top of the cover plate 7 is connected to the pull rope 22, and the other end of the pull rope 22 is connected to the swing frame 2.

[0031] like Figure 1 As shown, it also includes a telescopic pad 23. A telescopic pad 23 is provided between the fixing plate 13 and the liquid guiding plate 16. The upper end of the telescopic pad 23 is connected to the outer ring of the liquid guiding plate 16, and the lower end of the telescopic pad 23 is connected to the outer ring of the fixing plate 13.

[0032] The operator automatically transports the circular steel plate to the center of mold 3 for positioning, and the drive assembly starts and clamps the edge of the steel plate to make it rotate at high speed. The hydraulic cylinder on the side wall of the main frame 1 then pushes the swing frame 2 to swing down around the axis, driving the cylinder 11 installed on the upper end of the swing frame 2 to move synchronously; the cylinder 11 pushes out the connecting piece 12 through the piston rod, so that the spinning roller 4 is pressed against the surface of the rotating steel plate with constant pressure. The spinning roller 4 generates radial extrusion as the steel plate rotates, and the steel plate undergoes plastic deformation under continuous pressure, gradually bending and tightly fitting the curved surface of mold 3.

[0033] The moment the spinning roller 4 contacts the steel plate, the oil pump 10 starts simultaneously and draws lubricant from the storage box 6. The lubricant is then delivered to the nozzle 9 through the oil pipe 8. The lubricant is sprayed onto the contact area between the spinning roller 4 and the steel plate, forming a continuous oil film at the friction interface. This significantly reduces the coefficient of friction between the spinning roller 4 and the high-temperature steel plate, eliminating wear on the spinning roller 4 caused by relative sliding. At the same time, it cools the plastic deformation zone. As the steel plate is bent and formed, excess lubricant flows downward along the curved surface of the steel plate and is guided to the surface of the guide plate 16 through the edge of the mold 3.

[0034] After spinning is completed, the cylinder 11 of the swing frame 2 retracts, causing the spinning wheel 4 to detach from the pot body. At the same time, the drive component releases the forming pot body for easy removal. The lubricating fluid collected by the liquid guide plate 16 flows into the collection box 17 through the opening for temporary storage. The operator monitors the liquid level in real time through the observation window 21 of the storage box 6 and the collection box 17. When the liquid level in the storage box 6 is insufficient, the cover plate 7 is opened to add lubricant. The pull rope 22 suspends the cover plate 7 on the swing frame 2 to prevent loss. When the collection box 17 is full, it is pulled out. After impurities are filtered through the filter screen 19, the clean lubricating fluid can be returned to the storage box 6.

[0035] During the extrusion operation, the oil pipe 8, which swings down with the swing frame 2, presses the liquid guide plate 16 downward. The liquid guide plate 16 drives the guide rod 14 to slide along the inner hole of the fixed plate 13 and compress the return spring 15. When the swing frame 2 returns to its original position, the return spring 15 pushes the liquid guide plate 16 back to its initial height. The telescopic pad 23 extends and retracts synchronously during the lifting and lowering of the liquid guide plate 16, effectively sealing the moving cavity of the guide rod 14 and preventing metal debris from entering. After each batch of processing is completed, the operator rotates the scraper 18 inside the liquid guide plate 16 to thoroughly scrape the residual oil into the collection box 17. The handle 20 provides a gripping point, making it easier to apply force when pushing and pulling the collection box 17.
