[0002] Sheet metal is a comprehensive cold processing technology for thin metal plates, including shearing, punching / cutting / compounding, folding, welding, riveting, splicing, forming, etc. Its most notable feature is that the thickness of the same part is consistent. The products processed by the sheet metal process are called sheet metal parts. Sheet metal parts are widely used in home appliances such as air conditioners and washing machines. Taking the air conditioning application scenario as an example, the production requirement of the right side sheet metal of the air conditioner outdoor unit is relatively thin, which needs to be about 1mm. After the right side sheet metal part is produced by the mold, it will produce 100% stress deformation.

[0003] In order to meet the needs of automated production, the deformed right sheet metal parts are mostly manually reshaped and restored, but the efficiency is low and the restoration effect is poor. There are also sheet metal reshaping equipment on the market, for example, a Chinese patent with patent publication number CN220658798U discloses a sheet metal reshaping mechanism, but its structure is complex and the cost is high.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0039] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0040] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium.

The terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only implementation method.

[0042] like Figures 1 to 8As shown, an embodiment of the present invention provides a sheet metal shaping device, including a frame 30, a shaping table 40, at least one bottom positioning member 1, at least one first lateral positioning member 2, at least one second lateral positioning member 3, at least one pressing member 4, at least one first pushing member 5, at least one second pushing member 6 and at least one third pushing member 7. The shaping table 40 is arranged on the frame 30, the bottom positioning member 1 is fixed on the shaping table 40 and is located below the sheet metal 100, the first lateral positioning member 2 is arranged on the first lateral side 110 of the sheet metal, the second lateral positioning member 3 is arranged on the second lateral side 120 of the sheet metal, the pressing member 4 is arranged above the sheet metal 100, the first pushing member 5 is arranged on the outer side surface of the bending part 130 of the sheet metal, and is arranged opposite to the first lateral positioning member 2, the second pushing member 6 is arranged on the inner surface of the bending part 130 of the sheet metal, and is arranged opposite to the first pushing member 5, and the third pushing member 7 is arranged opposite to the second lateral positioning member 3.

[0043] Through the cooperation of the bottom positioning member 1, the first lateral positioning member 2, the second lateral positioning member 3, the first pushing member 5, the second pushing member 6 and the third pushing member 7, the multi-directional clamping of the sheet metal 100 is achieved. Specifically, the bottom positioning member 1 provides a stable reference surface to ensure the stable position of the sheet metal 100 during the entire shaping process. The first lateral positioning member 2, the second lateral positioning member 3, the first pushing member 5, the second pushing member 6 and the third pushing member 7 clamp the sheet metal 100 from different sides to limit its movement in the horizontal plane. The pressing member 4 is located above the sheet metal 100 and can apply vertical downward pressure to ensure that the sheet metal 100 will not move due to internal stress or external impact during the shaping process. The pressing member 4 cooperates with the bottom positioning member 1 to effectively clamp the sheet metal 100 and provide positioning in the upper and lower directions. The first pushing component 5 and the second pushing component 6 are respectively arranged on the outer side and the inner surface of the bending part of the sheet metal part 100. This design is particularly aimed at controlling the deformation of the bending part. Through the cooperation and clamping of the inner and outer sides, it is ensured that the bending part maintains a predetermined shape during shaping to avoid excessive deformation or position displacement.

[0044] The components used in this device have a simple structure and clear functions, and the various parts operate in a coordinated manner, reducing the risk of misoperation that may be caused by a complex structure. This design not only reduces manufacturing and maintenance costs, but also improves the efficiency of the shaping process.

[0045] In this embodiment, the first lateral direction refers to the front-to-back direction, and the second lateral direction refers to the left-to-right direction.

[0046] like Figure 1As shown, six bottom positioning members 1, two first side positioning members 2 and one second side positioning member 3 are distributed on the shaping table 40, wherein the two bottom positioning members 1 are respectively arranged near the left front edge and the right front edge of the shaping table 40, and the remaining four bottom positioning members 1 are respectively arranged side by side near the rear edge of the shaping table 40; the two first side positioning members 2 are arranged side by side near the middle position of the front edge of the shaping table 40; the second side positioning member 3 is arranged near the middle position of the right edge of the shaping table 40. In addition, the first pushing component 5 and the second pushing component 6 are arranged at the middle position near the rear edge of the shaping table 40, the third pushing component 7 is arranged near the center of the shaping table 40, and the two pressing components 4 are respectively arranged near the left edge and the right edge of the shaping table 40. As shown Figure 5 As shown, during shaping, the first pushing component 5 cooperates with the first lateral positioning component 2 to clamp the sheet metal part 100 in the first lateral direction for positioning, the second pushing component 6 cooperates with the first pushing component 5 to clamp the bending portion 130 of the sheet metal part for positioning, the third pushing component 7 cooperates with the second lateral positioning component 3, the third pushing component 7 corresponds to the central opening portion 140 of the sheet metal part, and clamps the sheet metal part 100 in the second lateral direction for positioning, the pressing component 4 cooperates with the bottom positioning component 1 to clamp the sheet metal part 100, and clamps the sheet metal part 100 in the up and down directions for positioning, and the shaping process is completed after the sheet metal part 100 is positioned as a whole.

[0047] like Figure 5 As shown, the top of the bottom positioning member 1 constitutes a supporting plane for the sheet metal part 100. When the sheet metal part 100 is placed on the supporting plane, at least parts of the first side positioning member 2 and the second side positioning member 3 extend above the supporting plane. This design ensures that when the sheet metal part 100 is placed on the supporting plane, the first side positioning member 2 can effectively limit the front and right sides of the sheet metal part 100, thereby preventing the sheet metal part 100 from moving forward or to the right.

[0048] In one embodiment, the sheet metal shaping device further includes a pressing power member 8 , and the pressing component 4 is transmission-connected to the pressing power member 8 . The pressing component 4 can move toward or away from the bottom positioning member 1 under the action of the pressing power member 8 .

[0049] like Figure 1 As shown, the pressing power member 8 can be a cylinder or an electric push rod. During operation, the pressing power member 8 is started in a controlled manner to move the pressing component 4 toward the sheet metal part 100. When the lower pressing plate 42 contacts the sheet metal part 100, downward pressure continues to be applied to press the sheet metal part 100 tightly against the supporting plane of the bottom positioning member 1. This vertical pressure helps to firmly fix the sheet metal part 100 in a predetermined position to prevent unnecessary displacement during the shaping process.

[0050] In one embodiment, the pressing component 4 includes a rotating bracket 41 and a pressing plate 42 . The rotating bracket 41 is connected to the pressing power member 8 , and the pressing plate 42 is connected to the rotating bracket 41 .

[0051] like Figure 4 As shown, the rotating bracket 41 is a fork-shaped structure, and the two sides of the rotating bracket 41 are hinged with the rotating shaft installed on the base, and the base is fixed on the frame 30. The pressing component 4 is connected to the rotating shaft and drives the rotating shaft to rotate, so that the rotating bracket 41 rotates, and the lower pressing plate 42 is fixedly connected to the tail of the rotating bracket 41. When the rotating bracket 41 rotates, the lower pressing plate 42 moves accordingly, so as to approach or move away from the bottom positioning member 1. When the pressing power member 8 is started, the rotating bracket 41 rotates under its drive, and the lower pressing plate 42 is pressed down on the sheet metal part 100 during the rotation process, applying the necessary pressure to position the sheet metal part 100. After the shaping work is completed, the pressing power member 8 moves in the opposite direction, and the rotating bracket 41 rotates back to the starting position to lift the lower pressing plate 42. By using the rotating bracket 41, the lower pressing plate 42 can achieve a flexible motion trajectory, while ensuring that the movement of the lower pressing plate 42 is stable and controlled, so that the pressing process can be uniformly applied, enhance the fixing effect of the sheet metal part 100, and maintain the shaping accuracy.

[0052] In one embodiment, the lower pressing plate 42 is provided with a lower pressing block 43 . When the lower pressing block 43 moves to contact the upper surface of the sheet metal component 100 , the lower pressing block 43 and the bottom positioning member 1 at the corresponding position below the sheet metal component 100 are in a vertical corresponding relationship.

[0053] like Figure 4 As shown, the lower pressing plate 42 is roughly U-shaped, and lower pressing blocks 43 are fixed to the ends of both sides of the lower pressing plate 42. The lower pressing blocks 43 can be square, circular or polygonal structural members. During operation, as the lower pressing power member 8 is activated, the lower pressing plate 42 drives the lower pressing block 43 to move downward. When the lower pressing block 43 moves to contact the upper surface of the sheet metal part 100, the vertical force applied by the lower pressing block 43 presses the sheet metal part 100 toward the bottom positioning member 1. By arranging the lower pressing block 43 on the lower pressing plate 42 and ensuring the accurate correspondence between it and the bottom positioning member 1, effective fixation and shaping of the sheet metal part 100 is achieved.

[0054] In one embodiment, the sheet metal shaping device further includes a first jacking force member 9 , the first jacking component 5 includes a first jacking plate 51 , and the first jacking force member 9 is transmission-connected to the first jacking plate 51 .

[0055] like Figure 1 , Figure 7As shown, the first push plate 51 can be a rectangular plate or a trapezoidal plate, etc., and the side of the first push plate 51 in contact with the sheet metal part 100 is a horizontal surface. The first push member 9 can be a cylinder or an electric push rod, which is used to provide a linear thrust. The piston rod (or push rod) of the first push member 9 is connected to the first push plate 51 by a transmission connection, and is fixed by bolts, clamps or welding to ensure the reliability of the transmission connection. During operation, after the first push member 9 is connected to the power source, the piston rod or push rod extends or retracts in a predetermined direction, driving the first push plate 51 to perform a linear motion.

[0056] In one embodiment, the sheet metal shaping device further includes a second jacking force member 10 , the second jacking member 6 includes a second jacking plate 61 , and the second jacking force member 10 is transmission-connected to the second jacking plate 61 .

[0057] like Figure 1 , Figure 8 As shown, the second push plate 61 can be a rectangular plate or a trapezoidal plate, etc., and the side of the first push plate 51 in contact with the sheet metal part 100 is a horizontal surface. The first push member 9 can be a cylinder or an electric push rod, which is used to provide a linear push force. The piston rod or push rod of the second push member 10 is connected to the second push plate 61 through a mechanical connection (such as bolt connection, welding or clamp fixation). This connection method ensures that the second push plate 61 can move linearly with the action of the second push member 10. The main function of the second push plate 61 is to assist the first push plate 51 in positioning and fixing the sheet metal part 100. In operation, after the second push member 10 is started, its piston rod or push rod pushes the second push plate 61 to contact the inner side of the sheet metal part 100, applies the required pressing force, and stably fixes the sheet metal part 100 in the shaping device. The movement direction of the second push plate 61 is opposite to the running direction of the first push plate 51, so as to provide a positioning and shaping effect on the sheet metal part 100.

[0058] In one embodiment, the third pushing component 7 includes a support seat 71 and a rotating push plate 72 . The support seat 71 is provided with a shaft rod 711 , and the rotating push plate 72 is movably disposed on the shaft rod 711 .

[0059] like Figure 1 , Figure 6As shown, the support seat 71 is the basic structure of the third push component 7. The support seat 71 is fixed to the shaping table 40 by screws. A shaft 711 is provided on the support seat 71. The shaft 711 can be cylindrical or other suitable structural shapes, which can support the rotational movement of the rotating push plate 72. The design of the shaft 711 allows the rotating push plate 72 to rotate freely thereon or swing within a certain range. The rotating push plate 72 can be connected to the shaft 711 through a bearing or a bushing to reduce friction and ensure smooth rotational movement. During operation, the rotating push plate 72 can rotate around the shaft 711, and through the rotation, it contacts the central opening part 140 of the sheet metal part and pushes the sheet metal part 100 to the right. Through the rotation function of the rotating push plate 72, it is convenient to act on the central opening part 140 of the sheet metal part, and the operation is more convenient.

[0060] In one embodiment, the sheet metal shaping device further includes a third top driving force member 20 , which is connected to the rotating push plate 72 , and the rotating push plate 72 rotates relative to the support seat 71 under the power of the third top driving force member 20 .

[0061] like Figure 6 As shown, the third push member 20 can be a cylinder or an electric push rod, which is used to provide a linear push force, and the connection between the rotating push plate 72 and the third push member 20 can be achieved through a connection mechanism such as a transmission rod, a connecting rod mechanism or a gear transmission. During operation, the power generated by the third push member 20 is transmitted to the rotating push plate 72 through the connection mechanism, so that the rotating push plate 72 rotates around the shaft 711 on the support seat 71, thereby pushing the central opening portion 140 of the sheet metal part.

[0062] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the present invention, and these modifications or replacements should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the protection scope of the claims.
