Due to the different needs of different buildings and customers, metal door and window processing can provide personalized customization services.

[0003] A Chinese patent discloses a cutting device for metal door and window processing (publication number CN220006172U), which includes an operating table, a support rod is fixedly arranged on the top wall of the operating table, and a cutting mechanism for cutting metal parts for door and window processing is arranged on the support rod; a cutting groove is opened on the operating table, and both sides of the cutting groove are slidably arranged with placement blocks in the direction of approaching or moving away from each other, and a fixing part for fixing the placement blocks is arranged on the operating table; each of the placement blocks is provided with an abutment plate for abutting against the metal parts for door and window processing. The application has the effect of reducing the labor intensity of the staff.

[0004] Therefore, based on the above search and in combination with the existing ones, when the above device is processing metal doors and windows, the abutment plate cannot fit on the outer surface of the metal door and window metal parts when limiting the metal doors and windows due to its shape, resulting in a smaller contact point between the abutment plate and the metal door and window metal parts, thereby reducing stability, causing the metal door and window metal parts to shake during the cutting process, resulting in the cutting point being offset, and affecting the quality of the finished product. Utility Model Content

[0005] The purpose of the utility model is to provide a cutting device for metal door and window processing to solve the problems raised in the above background technology.

[0008] The limiting structure comprises a bag, which is slidably mounted on the top of the bottom plate. The inner cavity of the bag is loaded with sand, and an air bag is arranged on the top of the sand.

[0009] As a further solution of the utility model, the adjustment assembly includes a push plate, the push plate is slidably connected to the inner cavity of the bottom plate, and the inner cavity of the push plate is fixedly connected with a spring for pushing the push plate to move.

[0013] As a further solution of the utility model, a leg for supporting the device is fixedly connected to the bottom of the base plate.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. When the utility model is used, a bag is provided and sand is loaded inside the bag.

[0023] The limiting structure 3 includes a bag 301, which is slidably installed on the top of the base plate 1. The inner cavity of the bag 301 is loaded with a sand body 302, and an air bag 303 is arranged on the top of the sand body 302. Specifically, after the bag 301 moves down to fit the top of the metal door and window metal parts, the air bag 303 is inflated and then squeezes the inner cavity of the bag 301, so that the sand body 302 is wrapped around the outer wall of the metal door and window metal parts. During the squeezing process, the gap inside the sand body 302 is reduced, the density of the sand body 302 is increased, and the overall hardness of the sand body 302 is increased, and the metal door and window metal parts are fixed. Because the sand body 302 is relatively loose and has strong plasticity, when in use, the contact area with the metal door and window metal parts is increased, thereby increasing stability, and at the same time, deformation of the metal door and window metal parts due to squeezing can also be avoided.

[0024] See also Figure 2 The adjustment component 2 includes a push plate 201, which is slidably connected to the inner cavity of the bottom plate 1. The inner cavity of the push plate 201 is fixedly connected with a spring 204 for pushing the push plate 201 to move. The inner cavity of the bottom plate 1 begins with a limiting groove 202 for limiting the push plate 201 to keep it in linear motion. The limiting groove 202 is slidably connected with a slider 203. The slider 203 is fixedly connected to the bottom of the push plate 201.

[0026] Example 2: Please refer to Figure 4 The cutting assembly 4 includes a cutting blade 401, which is rotatably connected to the top of the base plate 1. Both ends of the cutting blade 401 are rotatably connected to connecting strips 402 for driving the cutting blade 401 to move up and down. The outer wall of the connecting strip 402 is fixedly connected to a motor 403 for driving the cutting blade 401 to rotate. The output shaft of the motor 403 passes through the connecting strip 402 and is tightly inserted into the inner cavity of the cutting blade 401, so that when the motor 403 is working, its output shaft drives the cutting blade 401 to rotate, and a limiting belt 404 is provided on the outer wall of the motor 403.

[0029] The working principle of the utility model is:

[0030] First, place the metal door and window metal parts on the top of the bottom plate 1, so that the two sets of springs 204 push the metal door and window metal parts to the middle of the top of the bottom plate 1 from both ends through the push plate 201, and calibrate the metal door and window metal parts for cutting. Then drive the cylinder 305 to move the connecting shell 304 down to the bottom bag 301 to fit the outer surface of the metal parts. Then drive the air pump 306 to allow the gas to enter the inner cavity of the air bag 303 through the air pipe 308, so that the air bag 303 swells and squeezes the inner cavity of the bag 301, so that the sand body 302 is wrapped around the outer wall of the metal door and window metal parts. During the squeezing process, the gap inside the sand body 302 is reduced, so that its density becomes larger, thereby increasing the overall hardness of the sand body 302, and fixing the metal door and window metal parts. , when driving the motor 403, it drives the cutting blade 401 to rotate and cut the metal door and window metal parts, and at the same time drives the air pump 306 to transport gas to the inside of the strip bag 407 through the connecting pipe 408, so that when the strip bag 407 swells, the connecting strip 402 is squeezed to push the cutting blade 401 downward, thereby deeply cutting the metal door and window metal parts. After the cutting is completed, the air pump 306 can be driven again to discharge the gas in the inner cavity of the strip bag 407, so that the spring 2 406 pushes the cutting blade 401 to move up and reset through the connecting strip 402, and drives the air pump 306 again to evacuate the inside of the air bag 303, and drives the cylinder 305 to expand, and relax the metal door and window metal parts, so as to facilitate the removal of the cut metal door and window metal parts.
