Description

Technical Field

[0001] The utility model belongs to the technical field of kitchenware processing platforms, and particularly relates to a hydraulic curling device for kitchenware production. Background Art

[0002] Kitchenware is a general term for kitchen utensils, which mainly includes the following five categories. The first category is storage utensils; the second category is washing utensils; the third category is conditioning utensils; the fourth category is cooking utensils; the fifth category is dining utensils. When processing stainless steel kitchenware products, there will be burrs on the edges, which are likely to cause harm to users. Therefore, after the kitchenware is formed, a curling machine will be used again for curling treatment to make the edges smooth.

[0003] For the existing kitchenware forming and curling, separate machines are required for processing, which requires multiple steps of turnover, affecting the production efficiency of kitchenware. Moreover, separate forming and curling machines need to be purchased, resulting in a large cost investment. Content of the Utility Model

[0004] In order to solve the above technical problems, the utility model provides a hydraulic curling device for kitchenware production, and the adopted technical solution is as follows:

[0005] A hydraulic curling device for kitchenware production includes a base. Above the base, there is a rotating cylinder. Inside the base, there is an installation groove for placing a rotating motor, and the rotating motor is fixedly connected to the rotating cylinder above. Inside the rotating cylinder, there is a lifting hydraulic cylinder, and above the lifting hydraulic cylinder, there is a movable lifting bottom plate;

[0006] At one end of the upper surface of the base, there is a support frame. At the upper end of the support frame, there is a main hydraulic cylinder, and the telescopic rod of the main hydraulic cylinder is connected to the upper mold below; above the support frame and on both sides of the main hydraulic cylinder, there are respectively a pair of auxiliary hydraulic cylinders, and the telescopic rods below the pair of auxiliary hydraulic cylinders pass through the support frame and are connected to the bending sleeves below;

[0007] On one side of the support frame, there is a connecting frame. Above one end of the connecting frame, there is an adjusting hydraulic cylinder, and the telescopic rod of the adjusting hydraulic cylinder passes through the connecting frame and is connected to the forward hydraulic cylinder below. The end of the forward hydraulic cylinder facing the rotating cylinder is connected to a curling mold.

[0008] Further, outside the upper part of the upper mold, there are multiple connecting rods. The upper ends of the connecting rods pass through the pressing sleeve located above the upper mold. A spring is sleeved on the outer side of the section of the connecting rod passing through the pressing sleeve. Through the spring, the pressing sleeve can tightly press the plate placed above the rotating cylinder.

[0009] Furthermore, a plurality of clamping plates are provided on the outer side of the rotating motor, and sliding grooves for the clamping plates to be embedded and slide are provided on the inner side surface of the installation groove. This structure can enable the rotating motor to drive the upper rotating cylinder to rotate while also preventing the lower die from descending and exerting pressure on the rotating motor.

[0010] Furthermore, bumps are provided on the outer side of the lifting bottom plate, and moving grooves for the bumps to be embedded and slide are provided on the inner wall of the rotating cylinder. This structure facilitates pushing the kitchenware upward after the kitchenware is formed, so as to facilitate the progress of the kitchenware rolling process.

[0011] Furthermore, the height of the pressing sleeve is greater than the height of the upper die, and during the descending process, the pressing sleeve can contact the lower plate first before the upper die.

[0012] Furthermore, through holes for the connecting rods to pass through are respectively provided at the positions corresponding to the connecting rods in the support frame, which can prevent the connecting rods from being blocked when the upper die rises.

[0013] Furthermore, a magnet is provided on the upper end surface of the telescopic rod of the hydraulic cylinder itself, which adsorbs to the iron block placed in the kitchenware, and can realize that after the upper die rises, the kitchenware is still fixed in the rotating cylinder and rotates with the rotating cylinder.

[0014] Compared with the prior art, the present utility model has the following beneficial effects:

[0015] The present utility model can realize the forming of the plate through the upper die and the pressing sleeve, and can realize the curling work of the kitchenware after production through the bending sleeve and the curling die. Therefore, multiple steps of the kitchenware production can be completed at one time in this device, increasing the production efficiency of the kitchenware. There is no need to separately purchase additional machines for forming and curling, thus reducing the cost investment.

[0016] The height of the pressing sleeve in the present utility model is greater than the height of the upper die. During the descending process, the pressing sleeve can contact the lower plate first before the upper die. As the upper die and the connecting rod fixed above the upper die continue to descend, the spring is stressed and will further push the pressing sleeve to tightly press the plate, preventing the outer edge of the plate from shrinking and deforming when the upper die presses on the plate.

[0017] The present utility model is provided with a magnet on the upper end surface of the telescopic rod of the hydraulic cylinder. After contacting the lifting bottom plate, it can adsorb the iron block located in the kitchenware. Through the adsorption between the magnet and the iron block, the kitchenware can still be fixed after the lower die and the pressing sleeve rise, and rotate with the rotating cylinder for the curling work.

Detailed implementation manners

[0030] In order to enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0031] As shown in the appendix Figure 1-10 Shown.

[0032] A hydraulic curling device for kitchenware production, including a base 1. Above the base 1, there is a rotating cylinder 2. Inside the base 1, there is an installation groove 12 for placing a rotating motor 14. The rotating motor 14 is fixedly connected to the rotating cylinder 2 above. Outside the rotating motor 14, there are multiple clamping plates. On the inner side of the installation groove 12, there are sliding grooves 13 for the clamping plates to be embedded and slide. Through the above structural settings, the rotating cylinder 2 can rotate driven by the rotating motor 14.

[0033] Inside the rotating cylinder 2, there is a lifting hydraulic cylinder 21. Above the lifting hydraulic cylinder 21, there is a movable lifting bottom plate 22. Outside the lifting bottom plate 22, there are convex blocks. On the inner wall of the rotating cylinder 2, there are moving grooves 23 for the convex blocks to be embedded and slide. When the lifting hydraulic cylinder 21 is in a contracted state, the lifting hydraulic cylinder 21 does not contact the lifting bottom plate 22.

[0034] At one end of the upper surface of the base 1, there is a support frame 11. The support frame 11 is an L-shaped structure that can rotate 180°. At the upper end of the support frame 11 and directly above the rotating cylinder 2, a main hydraulic cylinder 3 is installed. The telescopic rod of the main hydraulic cylinder 3 is connected to the upper mold 4 below. Under the action of the main hydraulic cylinder 3, the lifting of the upper mold 4 can be realized.

[0035] Above the upper mold 4, at the outer edge position, there are multiple connecting rods 41. The number of the connecting rods 41 is specifically 6 - 8. The multiple connecting rods 41 are arranged at uniform intervals. The upper ends of the connecting rods 41 pass through a pressing sleeve 5 located above the upper mold 4. A spring 42 is sleeved on the outer side of a section of the connecting rod 41 passing through the pressing sleeve 5. The height of the pressing sleeve 5 is greater than the height of the upper mold 4. Therefore, when the pressing sleeve 5 descends to contact the upper surface of the upper mold 4, the lower end of the pressing sleeve 5 will extend beyond one end of the upper mold by a certain distance.

[0036] During operation, place the sheet required for cold pressing forming on the upper surface of the rotating cylinder 2, and then start the main hydraulic cylinder 3 to descend, so that the upper mold 4 and the pressing sleeve 5 descend. During the descent, the pressing sleeve 5 contacts the sheet below first. As the upper mold 4 and the connecting rod 41 fixed above the upper mold 4 continue to descend, the spring 42 is stressed and will further push the pressing sleeve 5 to tightly press the sheet, preventing the outer edge of the sheet from shrinking and deforming when the upper mold 4 presses on the sheet. After the upper mold 4 continues to descend to cold press the sheet into shape, the state of the device at this time is as shown in the appendix Figure 1 shown.

[0037] Above the support frame 11 and on both sides of the main hydraulic cylinder 3, a pair of auxiliary hydraulic cylinders 6 are respectively provided. The telescopic rod below the auxiliary hydraulic cylinder 6 passes through the support frame 11 and is connected to the bending sleeve 7 below. Driven by the auxiliary hydraulic cylinder 6, the bending sleeve 7 can be lifted and lowered. After the upper die 4 cold-presses the plate into shape, the auxiliary hydraulic cylinder 6 pushes the bending sleeve 7 downward to bend the corners of the plate protruding from the rotating cylinder 2. The state of the device after bending is as shown in the appendix Figure 2 shown

[0038] After the corners of the plate are bent, the main hydraulic cylinder 3 and the auxiliary hydraulic cylinder 6 drive the upper die 4, the pressing sleeve 5, and the bending sleeve 7 to rise all at the same time. When the upper die 4 rises, in order to prevent the connecting rod 41 from being blocked by the upper support frame 11, through holes 15 for the connecting rod 41 to pass through are provided at the positions corresponding to the connecting rod 41 in the support frame 11

[0039] A connecting frame 8 is installed on one side of the support frame 11. Above one end of the connecting frame 8, an adjusting hydraulic cylinder 81 is installed. The telescopic rod of the adjusting hydraulic cylinder 81 passes through the connecting frame 8 and is connected to the forward hydraulic cylinder 82 below. The adjusting hydraulic cylinder 81 can drive the forward hydraulic cylinder 82 to rise and fall. One end of the forward hydraulic cylinder 82 facing the rotating cylinder 2 is connected to a curling die 83

[0040] After the corners of the plate are bent and the upper die 4, the pressing sleeve 5, and the bending sleeve 7 all rise, then the curled edge of the bent corner can be operated by the curling die 83. The specific working process is as follows

[0041] After the upper die 4, the pressing sleeve 5, and the bending sleeve 7 all rise, an iron block is placed inside the formed kitchenware, as shown in the appendix Figure 10 shown. The lifting hydraulic cylinder 21 located inside the rotating cylinder 2 is started. A magnet 211 is provided on the upper end face of the telescopic rod of the hydraulic cylinder 21. After contacting the lifting bottom plate 22, it can adsorb the iron block located inside the kitchenware. A plurality of openings are provided inside the lifting bottom plate 22, which can reduce the obstruction to the magnetic force of the magnet. Through the adsorption between the magnet 211 and the iron block, the kitchenware can still be fixed after the lower die 4 and the pressing sleeve 5 rise

[0042] After the lifting hydraulic cylinder 21 contacts the lifting bottom plate 22, it continues to push the lifting bottom plate 22 and the formed kitchenware above the lifting bottom plate 22 to rise together. The upward travel distance is such that the bent corners outside the kitchenware can exceed the upper surface of the rotating cylinder 2

[0043] After the kitchenware rises out of the rotating cylinder 2 to a certain height, the forward hydraulic cylinder 82 and the adjustment hydraulic cylinder 81 start to work, moving the curling die 83 to the position of the corner of the kitchenware. At the same time, the rotating motor 14 inside the base 1 drives the rotating cylinder 2 and the kitchenware to rotate. While rotating, the curling die 83 curls the inner side of the kitchenware. At this time, the device structure is as shown in the appendix Figure 4 shown

[0044] After the curling is completed, the lifting hydraulic cylinder 21 contracts, causing the lifting bottom plate 22 to descend. As the lifting hydraulic cylinder 21 contracts until the lifting bottom plate 22 is blocked by the moving groove 23 and the two are separated, the formed kitchenware can be removed together with the iron block inside at this time, and the kitchenware production work can continue

[0045] Using the technical solution of the present invention, or a person skilled in the art being inspired by the technical solution of the present invention to design a similar technical solution and achieving the above technical effects shall fall within the protection scope of the present invention
