Description

Technical Field

[0002] A boiler is a device used to generate steam or hot water, widely used in power generation, industrial production, heating and other fields. It generates heat energy by burning fuels (such as coal, natural gas, oil, etc.) or using other energy sources (such as electricity) to heat water or other liquids, producing steam or hot water for various uses. The boiler inner lining plate, also called the furnace lining plate or protective plate, mainly protects the boiler structure and prevents the direct erosion and damage of high temperature and combustion products to the boiler body. It can also improve combustion efficiency and extend the service life of the boiler.

[0003] Existing traditional inner liner bending equipment uses an upper pressure block and a lower die to squeeze and bend the sheet metal, causing the front and rear parts of the sheet metal to warp during bending. The device cannot limit the sheet metal's position and requires manual assistance, which is not practical. Furthermore, although some traditional sheet metal bending machines allow manual movement of the sheet metal, it is difficult to ensure that the sheet metal's position is accurate and does not deviate, making them impractical. Therefore, a high-precision multi-directional bending device for boiler inner liner plates is proposed to solve the above problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figures 1-3 The present invention provides an embodiment of a high-precision multi-directional bending device for boiler inner lining plates, including a processing table 1, which is used to cooperate with the bending processing of boiler inner lining plates. A bending mechanism is provided on the upper part of the processing table 1 for bending the boiler inner lining plates. The bending mechanism includes an auxiliary component 2 and a bending component 4. The bending component 4 is provided in front of the auxiliary component 2. The auxiliary component 2 is used to position the plate material when cooperating with the bending component 4.

[0032] Furthermore, the bending assembly 4 includes a housing 41, which is used to connect various components. The housing 41 is fixedly connected to the processing table 1. Bending components are provided on both the upper and lower parts of the housing 41. Both bending components include guide rails 42, which are fixedly connected to the housing 41. Guide blocks 43 are slidably connected to the outside of the guide rails 42. These blocks can be electrically driven and are used to adjust the position of the bending head 45 to cooperate with the bending of the sheet metal. Hydraulic cylinders 44 are fixedly connected to the sides of the two guide blocks 43 that are close to each other. These cylinders are used to push the bending head 45 to perform bending operations on the sheet metal. Bending heads 45 are fixedly connected to the ends of the two hydraulic cylinders 44 that are close to each other.

[0033] Furthermore, the front of the top surface of the processing table 1 is provided with an installation groove 11, which is used to cooperate with the installation of the lower auxiliary plate 25. The lower auxiliary plate 25 is movably connected to the installation groove 11 by bolts. The middle of the top surface of the processing table 1 is provided with a fixing groove 12, which is used to cooperate with the installation of the feeding and positioning assembly 3.

[0034] like Figure 4As shown, the auxiliary component 2 includes a mounting frame 21, which is used to connect various components. The mounting frame 21 is fixedly connected to the processing table 1. An electric pressure rod 22 is installed on the top of the mounting frame 21, which is used to adjust the position of the fixing plate 23. The output end of the electric pressure rod 22 passes through and is movably connected to the mounting frame 21. The bottom of the output rod of the electric pressure rod 22 is fixedly connected to the fixing plate 23. The lower part of the fixing plate 23 is movably connected to the upper auxiliary plate 24. The lower part of the mounting frame 21 is provided with a lower auxiliary plate 25. The auxiliary plates can be replaced according to the actual bending requirements.

[0035] Please see Figure 5 The bending mechanism also includes a feeding and positioning assembly 3, which includes an outer frame 31 for connecting various components. The outer frame 31 is fixedly connected to the fixing groove 12. An electric telescopic rod 32 is installed on the top of the outer frame 31 for adjusting the position of the upper rotating roller 34. The output rod of the electric telescopic rod 32 passes through and is fixedly connected to the outer frame 31. The lower end of the output rod of the electric telescopic rod 32 is fixedly connected to the mounting frame 33. The feeding and positioning assembly 3 also includes two rotating rollers 34 for conveying the plate. The upper rotating roller 34 passes through and is rotatably connected to the mounting frame 33. The lower rotating roller 34 passes through and is rotatably connected to the outer frame 31. A motor 35 is fixedly connected to the lower left side of the outer frame 31 for driving the lower rotating roller 34. The output end of the motor 35 is fixedly connected to the lower rotating roller 34 via a coupling.

[0036] Furthermore, mounting plates 311 are fixedly connected to the left and right rear sides of the outer frame 31 for mounting electric push rods 36. Electric push rods 36 are installed on the sides of the two mounting plates 311 that are far apart from each other for adjusting the position of positioning rollers 37. The output rods of electric push rods 36 pass through and are movably connected to the mounting plates 311. Positioning rollers 37 are installed on the sides of the two electric push rods 36 that are close to each other for positioning the plate material.

[0037] Working principle: During processing, the inner protective plate to be bent is first placed on the processing table 1, allowing the plate to pass through the gap between the two rotating rollers 34 and the two auxiliary plates. The electric push rods 36 are turned on, causing the two electric push rods 36 to drive the two positioning rollers 37 to move towards the center, thereby restricting the two sides of the plate and preventing the plate from shifting during bending. Then, the electric telescopic rod 32 drives the mounting frame 33 to move downward, causing the mounting frame 33 to drive the connected rotating rollers 34 downward, thereby restricting the upper and lower parts of the plate with the two rotating rollers 34. Finally, the motor 35 is turned on, and the motor 35 will drive the plate towards the bending head 45 through the rotating rollers 34.

[0038] Once the sheet material is moved to the appropriate position, the electric pressure rod 22 can drive the fixed plate 23 to move downwards, so that the upper auxiliary plate 24 and the lower auxiliary plate 25 clamp and fix the sheet material. Then, according to the bending direction, the upper or lower bending part is selected, and the hydraulic cylinder 44 of the bending part is moved to the appropriate position through the guide block 43. Then, the hydraulic cylinder 44 is activated, so that the hydraulic cylinder 44 drives the bending head 45 to move towards the sheet material and pushes the sheet material to bend. Once one part of the sheet material is bent, the upper auxiliary plate 24 can be released by controlling the electric pressure rod 22, and then the sheet material is conveyed forward by the feeding and positioning assembly 3 to bend other parts of the sheet material.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
