Description

Technical Field

[0001] This utility model relates to the field of stainless steel barrel production technology, and in particular to an automatic stretching device for stainless steel barrels. Background Technology

[0002] Stainless steel is increasingly favored for its beautiful and shiny appearance, as well as its resistance to oxidation, corrosion, and high temperatures. Stainless steel buckets are produced through a metal stretching process. Round sheets are placed on a mold, and the powerful force of a stretching machine forces the material into a cylindrical shape. A stretching device is required during this process. A search revealed a Chinese patent publication number CN217393440U, which discloses an automatic stretching device for stainless steel barrels. The device includes a fixed base, on the upper surface of which a lower support rod, a lifting mechanism, an air pump, and a support back plate are respectively provided. A lower clamping ring is fixedly connected to the top of the lower support rod. This patent uses an air jet discharge mechanism to push the ejector plate out during discharge, causing the stainless steel barrel to separate from the upper surface of the stretching die. The flowing air forms a diaphragm between the stainless steel barrel and the stretching die. However, when the stainless steel sheet is placed in the stretching position, it is easy for the placement position to be offset. In order to avoid the stainless steel sheet being scrapped due to improper placement, it needs to be adjusted multiple times, which affects the processing efficiency. Utility Model Content

The telescopic end of the second hydraulic telescopic rod 5 is detachably and fixedly connected to a stretching top mold 6. The stretching top mold 6 is located inside the fixed ring 4 and is coaxial with the fixed ring 4. A driving cavity 9 is opened on the inner wall of the fixed ring 4. A threaded rod 12 is rotatably connected to the inner wall of the driving cavity 9. Multiple guide grooves 14 are opened on the top outer wall of the fixed ring 4. A movable block 15 is slidably connected to the inner wall of the guide groove 14. The movable block 15 is threadedly engaged with the outer wall of the threaded rod 12. A support ring 7 is provided on the inner wall of the fixed ring 4. A slot 8 is provided on the top outer wall of the fixed ring 4 near the support ring 7. Multiple limiting protrusions are fixedly connected to the side wall of the support ring 7 and are slidably engaged with the slot 8. The limiting protrusions and the slot 8 are fixedly connected by hexagonal bolts. The inner ring radius of the support ring 7 is greater than the outer diameter of the stretching die 6 and less than the maximum outer diameter of the outer die cover 3. A drive assembly for driving the threaded rod 12 to rotate is provided inside the fixed ring 4. A limiting block 16 is fixedly connected to the top outer wall of the movable block 15 near the stretching die 6 through a connecting assembly.

[0021] The connecting assembly includes a receiving groove 17 and a cavity 18. The receiving groove 17 is formed on the top outer wall of the movable block 15. The limiting block 16 is slidably engaged with the inner wall of the receiving groove 17. The cavity 18 is formed on the bottom outer wall of the limiting block 16. An elastic element 19 is provided inside the receiving groove 17. One end of the elastic element 19 is connected to the inner wall of the cavity 18. A guide hole 20 is formed on the bottom outer wall of the limiting block 16. A guide post is fixedly connected to the inner wall of the receiving groove 17 and is slidably connected to the guide hole 20.

[0022] The hydraulic telescopic rod 1, hydraulic telescopic rod 2, etc. are all electrically connected to the controller, which can be an existing mature device such as a computer that provides control.

[0023] Before processing, select and install the corresponding outer mold cover 3, stretching top mold 6, and support ring 7 according to the size of the stainless steel barrel to be processed. The drive assembly drives the threaded rod 12 to rotate, and the threaded rod 12 drives the moving block 15 to move. Adjust the position of the upper limit block 16 of the moving block 15 so that multiple limit blocks 16 can limit the stainless steel sheet used for stretching. Place the stainless steel sheet on the support ring 7. Multiple limit blocks 16 are located outside the stainless steel sheet to limit the stainless steel sheet, so that the center of the stainless steel sheet is aligned with the center of the stretching top mold 6. Then, the hydraulic telescopic rod 12 drives the outer mold cover 3 to move down. The outer mold cover 3 and the support ring 7 cooperate to clamp and fix the stainless steel sheet. When the outer mold cover 3 moves down, it will squeeze the limit block 16. The limit block 16 is pressed into the receiving groove 17 under the guidance of the guide hole 20. The elastic element 19 is compressed and deformed. Then, the hydraulic telescopic rod 25 pushes the stretching top mold 6 to move up to stretch the stainless steel sheet.

[0024] By incorporating a threaded rod 12, a guide groove 14, a moving block 15, and a limiting block 16, the stainless steel sheet can be positioned during placement, ensuring accurate placement and avoiding the need for multiple adjustments after placement.

[0025] With the connection component provided, the limiting block 16 can retract into the receiving groove 17 when the outer mold cover 3 moves down, so as to avoid affecting the clamping of the stainless steel sheet.

[0026] Example 2: An automatic stretching device for stainless steel barrels. This example is based on Example 1 and makes the following improvements, such as... Figure 1 , Figure 2 As shown, the drive assembly includes a rotating ring 10 and a gear 13.

A power assembly 21 for driving a threaded rod 12 to rotate is provided on the outside of the fixed ring 4.

[0027] When adjusting the position of the limit block 16, the power component 21 drives a threaded rod 12 to rotate, the threaded rod 12 drives the gear 13 to rotate, and the gear 13 and the gear ring 11 drive the rotating ring 10 to rotate. During the rotation of the rotating ring 10, the gear ring 11 drives the remaining gears 13 to rotate synchronously, so that multiple threaded rods 12 rotate synchronously, and at the same time adjust the position of multiple limit blocks 16.

[0028] With the addition of a driving component, the positions of multiple limit blocks 16 can be adjusted simultaneously, making operation convenient.

[0029] Working principle: Before processing, select and install the corresponding outer mold cover 3, stretching top mold 6, and support ring 7 according to the size of the stainless steel barrel to be processed. The power component 21 drives a threaded rod 12 to rotate, which in turn drives the gear 13 to rotate. Through the transmission meshing of the gear 13 and the gear ring 11, the rotating ring 10 is driven to rotate. During the rotation of the rotating ring 10, the gear ring 11 drives the remaining gears 13 to rotate synchronously, so that multiple threaded rods 12 rotate synchronously. The threaded rods 12 drive the moving block 15 to move. Adjust the position of the upper limit block 16 of the moving block 15 so that multiple limit blocks 16 can pull against each other. The stainless steel sheet used for stretching is placed on the support ring 7, and multiple limiting blocks 16 are located outside the stainless steel sheet to limit its movement, so that the center of the stainless steel sheet is aligned with the center of the stretching die 6. Then, the hydraulic telescopic rod 12 drives the outer die cover 3 to move down. The outer die cover 3 cooperates with the support ring 7 to clamp and fix the stainless steel sheet. When the outer die cover 3 moves down, it will squeeze the limiting blocks 16. The limiting blocks 16 are pressed into the receiving groove 17 under the guidance of the guide hole 20. The elastic element 19 is compressed and deformed. Then, the hydraulic telescopic rod 25 pushes the stretching die 6 to move up, stretching the stainless steel sheet.
