[0002] In the manufacturing of steam generator housings, sheet metal bending and forming is one of the core processes, and its quality directly affects key performance indicators such as the sealing performance and structural strength of the steam generator housing.

[0003] Traditional bending forming equipment can generally only bend sheet metal of a single specification, resulting in poor adaptability. While some bending forming equipment can adapt to bending sheet metal of different specifications, changing bending dies for different specifications is a very cumbersome process. It requires disassembling the original die, installing the new die, and performing precise adjustments and calibrations, which affects the bending quality and production efficiency of the sheet metal. Utility Model Content

[0004] In view of the above problems, the purpose of this utility model is to provide a sheet metal bending and forming device for steam generator housing, which aims to solve the problems of poor adaptability and low bending quality and production efficiency of existing sheet metal bending and forming devices for steam generator housing.

[0005] The present invention adopts the following technical solution:

The drive shaft of the lifting cylinder is connected to the bottom plate. A conveyor table that can move up and down is provided on the machine base between the two slides.

[0007] Furthermore, both ends of the support base are provided with positioning seats, and a pair of positioning grooves are opened on the positioning seats. The two ends of the base plate are provided with positioning posts corresponding to the positioning grooves.

[0008] Furthermore, the machine base has top openings facing both slides, and an adjusting screw is rotatably installed inside the machine base facing the top opening. Each adjusting screw is equipped with a threaded sleeve connecting seat, which is connected to the slide at the same position. The two adjusting screws are connected by a shaft coupling, and the threaded sections on the two adjusting screws are arranged in opposite directions. The machine base is equipped with a sliding motor, and the drive shaft of the sliding motor is connected to either adjusting screw.

[0009] Furthermore, the conveyor frame is provided with a pair of support guides facing downwards, the bottom of the support guides extending into the machine tool, the machine tool is provided with upper and lower cylinders, the drive shafts of the upper and lower cylinders are connected to the frame of the conveyor, and a limiting plate is provided at the bottom of one of the support guides.

[0010] Furthermore, the machine platform is equipped with a limiting component, which includes three moving modules, two of which are arranged laterally and distributed on the outside of the slide on the same side, and one moving module is arranged longitudinally and located at the tail of the conveyor.

[0019] To make the objectives, technical solutions, and advantages of this utility model patent clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0020] To illustrate the technical solution described in this utility model, specific embodiments are described below.

[0021] For ease of explanation, only the parts relevant to the embodiments of this utility model are shown.

[0022] Combination Figure 1-4 As shown, the sheet metal bending and forming device for the steam generator housing includes a machine base 1. The machine base 1 is provided with a pair of slides 2, which can move relative to each other. Support seats 3 and bending movable seats 4 are respectively provided at the inner and outer positions of the slides 2. A rotary motor 5 for driving the bending movable seats 4 to rotate is provided on the slides 2. A lifting frame 6 is provided with the top of the slides 2 facing downward. A pressure seat 8 is provided on the bottom plate 7 of the lifting frame 6. The outer side wall of the pressure seat 8 is inclined downward and outward to form a guide surface 9. The bottom of the guide surface 9 smoothly transitions with the bottom surface of the pressure seat. A lifting cylinder 10 is provided on the top of the slides 2. The drive shaft of the lifting cylinder is connected to the bottom plate 7. A conveyor table 11 that can move up and down is provided on the machine base 1 between the two slides.

[0023] When using this device to bend sheet metal, first adjust the distance between the two slides according to the dimensions of the sheet metal to be bent, ensuring the support base can stably support the sheet metal. Then, place the sheet metal to be bent on the conveyor table, at its highest position, where the conveyor height is slightly higher than the top of the support base. The conveyor table transports the sheet metal to the bending position between the two slides, and then lowers the entire conveyor table, placing both ends of the sheet metal onto the support bases of the two slides respectively.

[0024] Next, two lifting cylinders operate simultaneously, lowering the lifting frame and pressure seat so that the bottom surface of the pressure seat contacts and presses against the top surface of the sheet metal. Then, the rotary motor starts, driving the bending movable seat to rotate upwards, bending the edge of the sheet metal. During bending, the sheet metal moves along the guide surface of the pressure seat under the action of the bending movable seat, ensuring the smoothness of the bending process. After bending is complete, the rotary motor drives the bending movable seat to reset, the lifting frame also moves upwards, and the pressure seat rises and resets. The conveyor table rises, removing the bent sheet metal from the support and sending it to the next process, completing one bending operation.

[0025] Figure 3 In this structure, both ends of the support base 3 are provided with positioning seats 12, and each positioning seat 12 has a pair of positioning grooves 13. The two ends of the base plate 7 are provided with positioning posts 14 corresponding to the positioning grooves 13. During the bending process of the sheet metal, when the lifting frame moves downward, the positioning posts insert into the corresponding positioning grooves, enabling precise positioning of the lifting frame and its pressure seat, ensuring accurate positioning of the pressure seat during descent, thereby improving the accuracy of sheet metal bending.

[0026] As a preferred structure, such as Figure 2The machine base 1 has a top opening 15 facing two slides 2. An adjusting screw 16 is rotatably installed in the machine base 1 facing the top opening 15. Each adjusting screw is equipped with a threaded sleeve connecting seat 17, which is connected to the slide 2 at the same position. The two adjusting screws 16 are connected by a shaft coupling 18, and the threaded sections on the two adjusting screws 16 are arranged in opposite directions. The machine base 1 is equipped with a sliding motor 19, and the drive shaft of the sliding motor is connected to either adjusting screw.

[0027] In practical use, the distance between the two slides can be adjusted according to the specifications of the sheet metal. Specifically: when the sliding motor starts working, it drives one of the connected adjusting screws to rotate, which in turn drives the other adjusting screw to rotate synchronously through the coupling. Since the threaded sleeve connecting seat is connected to the slide, the rotation of the adjusting screw will cause the threaded sleeve connecting seat to move along the adjusting screw. Furthermore, the threaded sections on the two adjusting screws are set in opposite directions, thus achieving relative or opposite movement of the two slides. This structure can precisely control the movement distance and position of the slides, meeting the bending requirements of sheet metal of different specifications.

[0028] Combination Figure 1 The machine 1 is equipped with a limiting component, which includes three moving modules 20, two of which are arranged horizontally and distributed on the outside of the slide on the same side, and one moving module is arranged vertically and located at the tail of the conveyor. The moving end of each moving module is equipped with a baffle 21.

[0029] The three moving modules can independently control the movement of the baffles at their moving ends. The horizontally positioned baffles can limit the sheet metal from both sides, while the vertically positioned baffles can limit the sheet metal from the rear. These three baffles prevent the sheet metal from shifting during conveying and bending, further improving bending accuracy. Since the moving modules are existing technology and not the focus of this device, they will not be described in detail here.

[0030] In this device, such as Figure 2 The conveyor table 11 has a pair of downward-facing support guides 22, the bottom of which extends into the machine base 1. The machine base 1 contains up-and-down cylinders 23, whose drive shafts are connected to the frame of the conveyor table 11. One of the support guides 22 has a limiting plate 24 at its bottom. When the conveyor table needs to move up and down, the up-and-down cylinders activate, driving the frame to move up and down, thus adjusting the height of the conveyor table. The limiting plate restricts the upward travel of the conveyor table, preventing excessive upward movement and ensuring safe operation of the equipment.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
