Description

Technical Field

[0001] The utility model relates to the technical field of liquefied gas tank production, in particular to a stamping and forming device for liquefied gas tanks. Background Technique

[0002] A liquefied gas tank is a storage tank for storing liquefied gas. Such tanks are usually made of pressure-resistant materials and can withstand the state of liquefied gas under high pressure. They are widely used in household, industrial and commercial fields and are commonly used for cooking, heating, hot water and other purposes. The liquefied gas tank is formed by applying pressure to raw materials to make them take the shape of a liquefied gas tank in a mold. Its raw materials are usually circular. When producing liquefied gas tanks, a stamping and forming device for liquefied gas tanks will be used. However, most of the existing stamping and forming devices for liquefied gas tanks still have problems to be solved during use.

[0003] Before applying pressure to the raw materials, most of the existing stamping and forming devices for liquefied gas tanks need to position the raw materials. Usually, four conical platforms are arranged around the mold, and the raw materials are positioned through the inclined surfaces of the four conical platforms. However, the friction between the conical platforms and the raw materials may affect the accuracy of positioning the position of the raw materials, resulting in an unsatisfactory positioning effect. The deviation of the position of the raw materials will affect the quality of the product, and manual adjustment by workers is required. However, the raw materials need to be preheated before stamping, and the temperature is relatively high, making manual adjustment difficult. Therefore, it is necessary to design a stamping and forming device for liquefied gas tanks to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art and propose a stamping and forming device for liquefied gas tanks.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] The top of the two said arc plates is provided with a toothed connecting strip which is cooperatively connected with the toothed connecting strip, and the toothed connecting strip is connected with the toothed connecting strip by the toothed connecting strip. The tops are all fixedly connected with a sliding plate, the tops of the sliding plates are fixedly connected with a V-shaped plate, the four support columns are all sleeved with the same second mounting plate, the second mounting plate is fixedly connected to the supporting column, the second mounting plate is opened with four sliding grooves, the sliding plates are arranged in the sliding grooves, and the sliding plates are slidably connected to the second mounting plate. Since a technical means is adopted that can enable the four V-shaped plates to move close to the raw materials while lowering the punching head, when the V-shaped plates continue to move when they contact the raw materials, the V-shaped plates can position the raw materials, which effectively solves the problem that the friction between the conical table and the raw materials proposed in the background technology may affect the accuracy of positioning the raw materials, resulting in an unsatisfactory positioning effect, which may require manual adjustment by the staff, but the raw materials need to be preheated before stamping, the temperature is high, and the manual adjustment is difficult, thereby achieving the technical effect of facilitating the positioning of the raw materials of the liquefied gas tank, with low operating difficulty, ensuring the accuracy of positioning, and ensuring the normal progress of production work.

[0007] As a further solution of the utility model, a stamping die is fixedly connected to the bottom of the second mounting plate.

[0008] As a further solution of the utility model, a top material groove is provided at the bottom of the stamping die, a top plate is arranged in the top material groove, a groove matching the inner wall of the stamping die is provided at the top of the top plate, a second hydraulic push rod is provided at the bottom of the top plate, and the output end of the second hydraulic push rod is fixedly connected to the top plate.

[0009] As a further solution of the utility model, the second hydraulic push rod is embedded in the base, and the second hydraulic push rod is fixedly connected to the base.

[0010] As a further solution of the present utility model, a circular slide rail is fixedly connected to the bottom of the second mounting plate, an annular slider is slidably connected to the inner wall of the circular slide rail, and a circular ring is fixedly connected to the bottom of the annular slider.

[0011] As a further solution of the present utility model, the annular slider is slidably connected to the circular slide rail.

[0012] As a further solution of the present utility model, a punching head is fixedly connected to the bottom of the first mounting plate.

[0013] The beneficial effects of the present utility model are as follows:

[0014] In the present utility model: Since the technical means of moving the four V-shaped plates closer to the raw material while lowering the punching head is adopted, when the V-shaped plates continue to move after contacting the raw material, the V-shaped plates can position the raw material, effectively solving the problem that the friction between the conical table and the raw material in the background technology may affect the accuracy of positioning the position of the raw material, resulting in an unsatisfactory positioning effect, and it may be necessary for the staff to manually adjust. However, the raw material needs to be preheated before stamping, and the temperature is relatively high, making it difficult to manually adjust. Thus, the technical effects of facilitating the positioning of the raw material for the liquefied gas tank, having a low operation difficulty, being able to ensure the positioning accuracy, and ensuring the normal progress of the production work are achieved.

[0025] In this embodiment, a stamping die 18 is fixedly connected to the bottom of the second mounting plate 16 .

[0026] In this embodiment, a top material groove 19 is provided at the bottom of the stamping die 18, a top plate 20 is arranged in the top material groove 19, a groove matching the inner wall of the stamping die 18 is provided at the top of the top plate 20, and a second hydraulic push rod 21 is provided at the bottom of the top plate 20, and the output end of the second hydraulic push rod 21 is fixedly connected to the top plate 20.

[0030] In this embodiment, a stamping head 24 is fixedly connected to the bottom of the first mounting plate 5.

[0031] Working principle: When using this device, place the raw material of the liquefied gas tank on the top of the second mounting plate 16, extend the output end of the first hydraulic push rod 4. The first hydraulic push rod 4 will drive the first mounting plate 5 to descend. The first mounting plate 5 will descend along the support column 2. The first mounting plate 5 will not shift during movement. The descent of the first mounting plate 5 will also drive the stamping head 24 to descend and approach the raw material of the liquefied gas tank, and the raw material will be punched into the stamping die 18 for stamping and forming to make it into a liquefied gas tank. After stamping and forming, retract the output end of the first hydraulic push rod 4 to make the stamping head 24 rise away from the stamping die 18. Then extend the output end of the second hydraulic push rod 21. The output end of the second hydraulic push rod 21 will drive the top plate 20 to rise, push out the liquefied gas tank formed in the stamping die 18, and take away the formed liquefied gas tank.

The arc-shaped plate 8 will drive the circular ring 11 to rotate. The circular ring 11 will squeeze the I-shaped wheel 13. The movement of the I-shaped wheel 13 will drive the sliding plate 14 to move along the sliding groove 17. The sliding plate 14 will move closer to the raw material of the liquefied gas tank. The movement of the sliding plate 14 will also drive the V-shaped plate 15 to move until the V-shaped plate 15 contacts the raw material. At this time, the continuous movement of the V-shaped plate 15 can position the raw material. After the sliding rod 7 moves into the vertical groove 10, the positioning of the raw material of the liquefied gas tank can be completed. When the first mounting plate 5 rises, it will drive the connecting plate 6 to rise. When the sliding rod 7 moves into the arc-shaped inclined groove 9 again, the sliding rod 7 will squeeze the arc-shaped plate 8 again to make the arc-shaped plate 8 perform a reverse circular motion, so that the arc-shaped plate 8 returns to the initial position, and the four V-shaped plates 15 can return to the initial position. Then continue the stamping and forming work according to the same steps. When the circular ring 11 rotates, it will also drive the circular slider 22 to rotate. The circular slider 22 will rotate along the circular slide rail 23, and the circular ring 11 will not shift during rotation.
