The device involves passing the curtain support to be bent through a module seat on a machine base and extending it between a stamping part and a buffer component in a bending assembly. The stamping part presses the curtain support, causing it to abut against a stop plate in the buffer component. As the stamping part moves gradually with the assistance of a second push rod component, the curtain support bends. Since the liquid storage pipe in the cooling assembly is located above the support frame, a nozzle sprays liquid from the storage pipe onto the surface of the curtain support, providing lubrication and facilitating bending. After bending, a cutting component in the slitting assembly, in cooperation with the first push rod component, completes the slitting of the curtain support. This allows for the completion of both slitting and bending operations on a single machine, improving production efficiency while ensuring bending accuracy. Attached Figure Description

[0045] Reference Figures 1-4 A slitting and bending device for producing smoke curtains includes a machine base 1, on which a cutting mechanism is provided. The cutting mechanism includes a module base 2 and a slitting assembly 3. The module base 2 is used for the passage of the curtain support and has a slot. The slitting assembly 3 is used to slitting the curtain support located in the module base 2. The module base 2 is set on the machine base 1. The slitting assembly 3 includes a support base 31 and a first push rod component 32. The support base 31 is set on the machine base 1. The first push rod component 32 is set on the support base 31. The piston end of the first push rod component 32 passes through the support base 31 and is equipped with a cutter component 321. The cutter component 321 is located above the module base 2.

[0046] A support frame 4 is provided on one side of the machine base 1. The support frame 4 has a hollow part 41. Several spaced sliding roller components 42 are provided on the hollow part 41. A bending component 5 is provided on the support frame 4. The bending component 5 includes a second push rod component 51 and a buffer component 52 located on both sides of the support frame 4. A stamping part 511 is installed on the piston end of the second push rod component 51. The second push rod component 51 can drive the stamping part 511 to move in position. The stamping part 511 is set with an arc structure, so that it can bend the vertical support. The buffer component 52 includes a support seat 521 and a bearing seat 522. Two sets of bearing seats 522 are provided and spaced on both sides of the support seat 521. The bearing seat 522 has a slot. A shaft 5221 is provided in the slot. A backing plate 523 is rotatably provided on the shaft 5221. A bending area through which the vertical support passes is formed between the backing plate 523 and the stamping part 511.

[0047] The support frame 4 is also equipped with a cooling component 6, which includes a support 61. The support 61 is mounted on the support frame 4. One end of the support 61 is equipped with a liquid storage pipe 62 located above the bending component 5. The liquid storage pipe 62 can store lubricant or coolant. The liquid storage pipe 62 is equipped with a nozzle 63 facing the bending area. The nozzle 63 can be a water mist nozzle in the prior art. By setting the nozzle 63, the liquid in the liquid storage pipe 62 can be sprayed onto the vertical wall support, which can realize the cold working of the vertical wall support, facilitate the bending of the vertical wall support, or spray cleaning of the vertical wall support, thereby realizing the cold working of the vertical wall support.

[0048] Based on the above structure, by passing the vertical wall bracket through the module seat 2 on the machine base 1 and extending it to the sliding roller component 42 of the support frame 4, the vertical wall bracket is positioned between the stamping part 511 and the abutment plate 523 by the movement of the sliding roller component 42. Subsequently, the stamping part 511 moves in cooperation with the first push rod component 32, causing one end of the stamping part 511 to abut against the vertical wall bracket and drive the vertical wall bracket to move towards the position of the abutment plate 523 and abut against the abutment plate 523. Then, the pressure applied by the stamping part 511 causes the vertical wall bracket to gradually bend, and the abutment plate 523 changes its angle in cooperation with the shaft 5221, thereby causing the vertical wall bracket to gradually bend and form. Since the liquid storage pipe 62 of the cooling component 6 is located above the support frame 4, therefore... When the stamping part 511 bends the vertical wall bracket, the coolant in the liquid storage pipe 62 is sprayed onto the surface of the vertical wall bracket through the nozzle 63, thereby forming an oil film on the surface of the vertical wall bracket, effectively reducing friction and facilitating the bending of the vertical wall bracket. After bending is completed, the first push rod component 32 in the slitting assembly 3 drives the cutting component 321 to move, so that the cutting component 321 is embedded in the module seat 2 to complete the slitting operation of the vertical wall bracket. Through the cooperation of the slitting assembly 3 and the bending assembly 5, the bending and slitting operations of the vertical wall bracket can be realized. Furthermore, the setting of the cooling assembly 6 can improve the processing efficiency during the bending process, solving the problem that the bending of the existing vertical wall bracket requires manual operation, resulting in accuracy deviation and low efficiency.

[0049] The first push rod component 32 and the second push rod component 51 can be any one of the pneumatic push rod, hydraulic push rod and electric push rod in the prior art.

[0050] In one embodiment, reference is made to Figure 1 , Figure 3 and Figure 6 The support frame 4 is also provided with a limiting component 7. There are two sets of limiting components 7 symmetrically distributed on both sides of the support frame 4. The limiting component 7 is used to restrict the movement path of the vertical wall support when it does not need to be bent, so as to avoid the vertical wall support from shifting its position during movement.

[0051] The limiting component 7 includes a mounting frame 71 and a limiting plate 72. The portion of the mounting frame 71 above the hollowed-out portion 41 is provided with a groove 711 communicating with the hollowed-out portion 41. The limiting plate 72 is provided with a mounting portion 721, which is movably mounted on the groove 711. A portion of the limiting plate 72 passes through the groove 711 and is located above the sliding roller component 42. A limiting area through which the vertical wall support passes is formed between the two sets of limiting plates 72. When the vertical wall support moves, it is located between the two sets of limiting plates 72, so that the vertical wall support can only move along the length direction of the limiting plate 72.

[0052] With the cooperation of the mounting part 721, the limiting plate 72 can move relative to the slide groove 711 along its length, expanding or shrinking the limiting area. By moving the limiting plate 72 on the slide groove 711, it is possible to adjust the width according to the size of the vertical wall bracket, thus making it suitable for vertical wall brackets of different sizes and improving the flexibility of the limiting component 7.

[0053] In one embodiment, reference is made to Figure 1 , Figure 2 and Figure 4 The buffer component 52 also includes an elastic element 524. The elastic element 524 adopts a pressure spring or a telescopic spring in the prior art. One end of the elastic element 524 is connected to the support base 521, and the other end is connected to a reset plate 525. The two ends of the reset plate 525 abut against two sets of abutment plates 523 respectively. When the elastic element 524 drives the reset plate 525 to reset, it can drive the abutment plates 523 to change their position.

[0054] When the abutment plate 523 rotates with the cooperation of the shaft 5221, the abutment plate 523 and the reset plate 525 are in line-to-surface contact. When the abutment plate 523 and the reset plate 525 are parallel to each other, the abutment plate 523 and the reset plate 525 are in surface-to-surface contact. Since the vertical wall support is located between the abutment plate 523 and the stamping part 511, the bending operation of the stamping part 511 on the vertical wall support will drive the abutment plate 523 to rotate. After the processing is completed, the rotation angle of the abutment plate 523 remains unchanged. Therefore, with the cooperation of the elastic element 524, the reset plate 525 can drive the abutment plate 523 to reset, so that the abutment plate 523 and the reset plate 525 remain parallel, which facilitates the subsequent bending operation.

[0055] In one embodiment, reference is made to Figure 1 and Figure 4 The bottom of the support frame 4 is also provided with a liquid collection tank 8. Since the liquid collection tank 8 is located below the cooling component 6, it can collect the liquid sprayed by the nozzle 63. The liquid collection tank 8 is located below the bending component 5. The liquid collection tank 8 has an opening that communicates with the hollow part 41. A filter plate 81 is installed in the opening. Since some impurities of the vertical support may enter the liquid collection tank 8 along with the sprayed liquid during the bending process of the vertical support, the filter plate 81 can be used to screen the impurities and prevent them from mixing with the liquid. This also facilitates the recycling of the liquid in the liquid collection tank 8. A discharge valve is provided at the bottom of the liquid collection tank 8.

[0056] In one embodiment, reference is made to Figure 1 and Figure 5The liquid storage pipe 62 is provided with an inlet port 621 that communicates with the interior. The inlet port 621 can be used to connect the liquid storage pipe 62 with the external cooling liquid, so that the cooling liquid is delivered into the liquid storage pipe 62. Several nozzles 63 are provided and distributed at intervals along the length of the liquid storage pipe 62. Several nozzles 63 can uniformly spray the vertical wall support, thereby completing the cold bending process of the vertical wall support.

[0057] In one embodiment, reference is made to Figure 1 , Figure 3 and Figure 6 The limiting component 7 also includes a pin 73, which serves as a limiting support. The slide groove 711 has through holes 7111 on both sides, which are spaced apart along the length of the slide groove 711. The mounting part 721 has mounting holes with the same diameter as the through holes 7111. When the mounting hole is aligned with one of the through holes 7111, the pin 73 passes through the through holes 7111 and the mounting hole. The same hole diameter facilitates the insertion of the pin 73. By passing the pin 73 through the mounting hole and the through hole 7111, the mounting part 721 can be limited, thereby fixing the limiting plate 72 and preventing the limiting plate 72 from shaking.

[0058] In one embodiment, reference is made to Figure 1 , Figure 2 and Figure 4 Guide rods 526 are provided on both sides of the reset plate 525. The presence of guide rods 526 on both sides can prevent positional deviation caused by unilateral guidance. One end of the guide rod 526 extends to the outside of the support base 521. The guide rod 526 is located inside the elastic member 524. When the reset plate 525 moves relative to the support base 521 with the cooperation of the elastic member 524, the portion of the guide rod 526 outside the support base 521 increases or decreases. The guide rod 526 is connected to the reset plate 525 and can guide the reset plate 525 when it moves with the cooperation of the elastic member 524, thereby preventing the elastic member 524 from deforming during movement and causing the position of the reset plate 525 to change.

[0059] In one embodiment, reference is made to Figure 1 , Figure 2 and Figure 4The sliding roller component 42 includes a support rod 421 and a roller component 422. The two ends of the support rod 421 are respectively connected to the inner wall of the hollow part 41. The roller component 422 is rotatably mounted on the support rod 421. When the vertical wall support is on the sliding roller component 42, it is in contact with the outer periphery of the roller component 422. Since the roller component 422 is rotatably mounted on the support rod 421, the roller component 422 can move when the vertical wall support moves, thereby reducing the friction generated when the vertical wall support moves and further improving the smoothness of the vertical wall support movement.

[0060] In one embodiment, reference is made to Figure 1 , Figure 2 and Figure 4 Both the backing plate 523 and the reset plate 525 have slots for placing the smoke curtain bracket on the side facing the stamping part 511. Since the smoke curtain bracket is a rectangular structure, the slots facilitate the insertion of the bracket, thereby enabling the smoke curtain bracket to be engaged and facilitating the bending operation of the bracket.

[0061] In one embodiment, reference is made to Figure 1 and Figure 2 Support legs 43 are provided around the bottom of the support frame 4. The support legs 43 can support the support frame 4 and distribute the pressure exerted by the vertical wall support and components on the support frame 4.
