As an important component of the ventilation system, the ventilation grille is installed at the inlet or outlet of the ventilation duct, serving multiple functions including guiding airflow, regulating ventilation volume, and preventing foreign objects from entering the ventilation duct.

[0003] Currently, such as Figure 4 As shown, the non-through ventilation holes of the grille are mostly processed manually. Operators need to use various tools to bend and separate the grille panels according to design requirements to form the required ventilation hole structure.

[0004] However, this approach presents the following technical problems: manual processing relies heavily on the experience and skill level of the operators, making it difficult to ensure that the size and shape of each ventilation hole are completely consistent, resulting in poor product consistency and increasing the workload of subsequent processing and inspection. Moreover, manual processing is cumbersome, time-consuming, labor-intensive, and inefficient.

[0005] In view of the above, this utility model is hereby proposed. Utility Model Content

[0006] The purpose of this utility model is to provide a stamping device for ventilation system grilles, to solve the technical problems of existing grille non-through ventilation holes, which are mostly processed manually, susceptible to human error, resulting in poor product consistency, time-consuming, labor-intensive, and inefficient production. The preferred technical solutions provided by this utility model and their various technical effects are detailed below.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] This utility model provides a stamping device for a ventilation system grille, including a frame and a stamping mechanism. The stamping mechanism includes a stamping cylinder, a stamping base, a first stamping component, and a second stamping component. The fixed end of the stamping cylinder is connected to the frame, the first stamping component is connected to the movable end of the stamping cylinder, the stamping base is adjustablely connected to the frame, the second stamping component is disposed on the stamping base, and its upper surface is provided with a stamping groove adapted to the ventilation holes of the grille.

The side of the first straight section is a straight surface, and the sides of the first arc-shaped section, the second straight section, and the second arc-shaped section are all arc surfaces that gradually curve inward from top to bottom.

[0010] Preferably, the side of the first straight section of the stamping block is flush with the side of the first stamping part.

[0011] Preferably, the second stamped part has a downward recess on one side of the second straight section near the stamping groove to form a relief portion.

[0012] Preferably, the outer wall of the telescopic rod of the stamping cylinder is provided with an external thread section, and the upper surface of the first stamping part is provided with a threaded sleeve, the threaded sleeve having an internal thread section that is adapted to the external thread section.

[0013] Preferably, the four sides of the stamping base are provided with elongated adjustment grooves, and the base plate of the frame is provided with fixing holes that are adapted to the adjustment grooves.

[0014] Preferably, a connecting plate is movably disposed on the adjusting groove, and a connecting hole is provided on the connecting plate. A bolt passes through the connecting hole and the adjusting groove and is connected to the fixing hole.

[0016] The preferred technical solution of this utility model can also produce at least the following technical effects: This invention effectively avoids the technical problems existing in the prior art where the processing of non-through ventilation holes in grilles mostly relies on manual operation, which is easily affected by human factors, resulting in operational errors, poor product consistency, time and labor costs, high labor intensity, and low production efficiency.

[0017] This utility model provides a stamping device for a ventilation system grille, including a frame and a stamping mechanism. The stamping mechanism includes a stamping cylinder, a stamping base, a first stamping part, and a second stamping part. The fixed end of the stamping cylinder is connected to the frame, the first stamping part is connected to the movable end of the stamping cylinder, the stamping base is adjustablely connected to the frame, the second stamping part is disposed on the stamping base, and its upper surface is provided with a stamping groove adapted to the ventilation holes of the grille.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] like Figures 1-3 As shown, this utility model provides a stamping device for a ventilation system grille, including a frame 1 and a stamping mechanism. The stamping mechanism includes a stamping cylinder 2, a stamping base 3, a first stamping part 4, and a second stamping part 6. The fixed end of the stamping cylinder 2 is connected to the frame 1, the first stamping part 4 is connected to the movable end of the stamping cylinder 2, the stamping base 3 is adjustablely connected to the frame 1, the second stamping part 6 is disposed on the stamping base 3, and its upper surface is provided with a stamping groove 601 that matches the ventilation hole 1001 of the grille. The lower surface of the first stamping part 4 is provided with a stamping block 5 that matches the stamping groove 601.

[0026] The frame 1 serves as the support frame for the stamping device, providing a stable mounting base for the stamping mechanism. The stamping cylinder 2 acts as a power source, driving the first stamping part 4 to move the stamping block 5 vertically, i.e., towards or away from the stamping groove 601.

[0027] The operator simply places the grating plate 10 in the appropriate position and then activates the stamping cylinder 2. The stamping cylinder 2 drives the first stamping member 4 to move downwards. When the stamping block 5 contacts the grating plate 10, as the first stamping member 4 continues to move downwards, the stamping block 5 enters the stamping groove 601. Under the constraint and guidance of the stamping groove 601, the stamping block 5 applies pressure to the grating plate 10, causing the grating plate 10 to deform according to the shape of the stamping groove 601 and the stamping block 5, forming the required non-through ventilation hole 1001.

[0028] Operators no longer need to perform tedious manual operations; they only need to place the grating plate 10 and start the cylinder, greatly reducing labor intensity. At the same time, by reducing human intervention and avoiding potential errors from manual operation, product quality is effectively improved. Furthermore, the automated stamping process is fast and continuous, increasing production efficiency.

[0029] As an optional implementation, such as Figure 2 As shown, the stamping block 5 includes a first straight section 501, a first arc-shaped section 502, a second straight section 503, and a second arc-shaped section 504 connected in sequence. The side of the first straight section 501 is a straight surface, and the sides of the first arc-shaped section 502, the second straight section 503, and the second arc-shaped section 504 are all arc surfaces that gradually curve inward from top to bottom.

[0030] Furthermore, the sides of the first arc-shaped segment 502, the second straight segment 503, and the second arc-shaped segment 504 gradually curve inward from the side closer to the first straight segment 501 to the side farther away from the first straight segment 501 along the thickness direction of the stamping block 5, forming an arc surface.

[0031] like Figure 3 As shown, the shape of the stamping groove 601 is adapted to the stamping block 5, specifically including a first straight groove segment 6011, a first arc-shaped groove segment 6012, a second straight groove segment 6013, and a second arc-shaped groove segment 6014 connected in sequence and corresponding to each segment of the stamping block 5. The first straight groove segment 6011 corresponds to the first straight segment 501 of the stamping block 5, and its side surface is a straight surface, matching the straight side surface of the first straight segment 501, to accommodate the first straight segment 501, so that the first straight segment 501 can be smoothly embedded during the stamping process. The first arc-shaped groove segment 6012 is adapted to the first arc-shaped segment 502 of the stamping block 5. The second straight groove segment 6013 corresponds to the second straight segment 503 of the stamping block 5. The second arc-shaped groove segment 6014 is adapted to the second arc-shaped segment 504 of the stamping block 5. The sides of the first arc-shaped groove segment 6012, the second straight groove segment 6013, and the second arc-shaped groove segment 6014 are all arc surfaces that gradually curve inward from top to bottom.

[0032] As an optional implementation, the side of the first straight section 501 of the stamping block 5 is flush with the side of the first stamping part 4.

[0033] During the stamping operation, when the stamping block 5 presses downwards against the grating plate 10, the first straight section 501 contacts the grating plate 10 with its straight side surface and cooperates with the stamping groove 601. Under the action of the stamping force, the grating plate 10 is cut open at that position, forming a straight cut. At the same time, under the action of the stamping force, the first arc-shaped section 502, the second straight section 503, and the second arc-shaped section 504 will generate a gradually changing squeezing and bending force on the grating plate 10, causing the grating plate 10 to gradually bend and deform at the corresponding position, forming a corresponding arc-shaped structure according to the shape of the side surface of the stamping block 5.

[0034] As an optional implementation, the second stamping member 6 is recessed downward on one side of the second straight section 503 near the stamping groove 601 to form a relief portion 602.

[0035] With this configuration, during the stamping and movement of the grating plate 10, the operator's hands can be naturally placed at the clearance part 602 of the second stamping part 6.

[0036] As an optional implementation, an external thread section 2011 is provided on the outer wall surface of the telescopic rod 201 of the stamping cylinder 2, and a threaded sleeve 8 is provided on the upper surface of the first stamping part 4. The threaded sleeve 8 has an internal thread section that is adapted to the external thread section 2011.

[0037] The threaded sleeve 8 and the telescopic rod 201 are screwed together to achieve a stable connection between the first stamping part 4 and the telescopic rod 201 of the stamping cylinder 2. The structure is simple and easy to assemble and disassemble. Moreover, during the stamping process, the first stamping part 4 moves precisely and synchronously with the telescopic rod 201, which improves the stability and reliability of the stamping operation.

[0038] As an optional implementation, the four sides of the stamping base 3 are respectively provided with elongated adjustment grooves 301, and the base plate of the frame 1 is provided with fixing holes that are adapted to the adjustment grooves 301.

[0039] Furthermore, the adjustment groove 301 is located at the middle position on the side of the stamping base 3 and extends toward the center of the stamping base 3.

[0040] As an optional implementation, a connecting plate 9 is movably provided on the adjusting groove 301. The connecting plate 9 has a connecting hole, and the bolt passes through the connecting hole and the adjusting groove 301 and is connected to the fixing hole.

[0041] Furthermore, the width of the connecting plate 9 is greater than the width of the adjusting groove 301, and the width of the adjusting groove 301 is greater than the outer diameter of the bolt.

[0042] During installation, the bolts are passed sequentially through the connecting holes and adjusting grooves 301 of the connecting plate 9 and connected to the fixing holes of the base plate. Since the width of the adjusting groove 301 is greater than the outer diameter of the bolt, a certain amount of movement is reserved for the bolt within the adjusting groove 301. After the initial connection of the bolts is completed, the position of the stamping base 3 can be finely adjusted. Specifically, by moving the stamping base 3, the relative position of the adjusting groove 301 and the bolt is changed. When the stamping base 3 is adjusted to a suitable position, that is, when the stamping groove 601 and the stamping block 5 can be aligned, the bolts are tightened, thereby fixing the relative positions of the connecting plate 9, the stamping base 3, and the base plate.

[0043] As an optional implementation, such as Figure 1 As shown, it also includes an auxiliary ruler 7. The side plates of the frame 1 are respectively provided with slide rails 101. The auxiliary ruler 7 is U-shaped, and its two wing plates 701 are slidably engaged with the slide rails 101. Multiple adjustment holes 7011 are provided on the wing plates 701, and positioning holes that match the adjustment holes 7011 are provided on the slide rails 101. The web plate 702 of the auxiliary ruler 7 is provided with scale lines 7021.

[0044] Furthermore, the slide rail 101 extends in a direction parallel to the first straight section 501. Through the sliding engagement of the wing plate 701 with the slide rail 101, the auxiliary ruler 7 can move smoothly in the horizontal direction along the slide rail 101, moving closer to or away from the second stamping part 6.

[0045] The auxiliary ruler 7 has a certain thickness. With this setting, the operator does not need to use other tools for positioning when moving the grating plate 10. He only needs to abut the side of the grating plate 10 against the web plate 702 of the auxiliary ruler 7 and move it along it, which simplifies the operation process and improves work efficiency.

[0046] The scale line 7021 on the web plate 702 provides a precise reference for the movement of the grating plate 10. Operators can accurately determine the position of the ventilation holes 1001 based on the scale line 7021, thus improving product quality. Specifically, operators can accurately determine the position of the next ventilation hole 1001 based on the already stamped position of the ventilation hole 1001, and move the grating plate 10 to ensure that the position of each ventilation hole 1001 meets the design requirements.

[0047] Through the screw connection of bolts, adjusting holes 7011 and positioning holes, and the sliding connection of slide rail 101 and wing plate 701, when it is necessary to adjust the position of auxiliary ruler 7 according to the size of different specifications of grating plate 10, the operator only needs to push the auxiliary ruler 7 along slide rail 101 to the appropriate position, so that the corresponding adjusting hole 7011 is aligned with the positioning hole on slide rail 101. Then, by passing bolts through the aligned positioning hole and adjusting hole 7011 in sequence, the auxiliary ruler 7 is firmly fixed on the frame 1, realizing the precise positioning of the auxiliary ruler 7. This allows the position of the auxiliary ruler 7 to be flexibly adjusted, enabling the stamping device to adapt to the stamping processing of grating plates 10 of different specifications and sizes, improving the versatility and flexibility of the device, and reducing production costs.
