[0015] Compared with the known prior art, the technical solution provided by the present invention has the following beneficial effects:

[0016] 1. Through the positioning component, adjustment component and stabilizing component in the clamping mechanism, the door and window frame bars can be clamped and buffered and supported when the door and window frame bars are bent. Among them, the positioning component cooperates with the clamping block to clamp the door and window frame bars between the positioning component and the clamping block, and the spacing between the positioning component and the clamping block is adjusted by rotating the adjustment component forward and backward, so as to clamp door and window frame bars of different specifications.

[0017] 2.

[0018] 3. Through the adjustable pressure relief valve and air release component in the injection mechanism, the gas and liquid that are gradually released as the bending angle of the door and window frame changes can be depressurized and separated. Among them, the adjustable pressure relief valve is used to reduce the pressure of the gas and liquid released from the door and window frame, so that the gas and liquid return to normal pressure value, and the air release component is used to release the gas in the gas and liquid, so that only the liquid is retained, and the retained liquid is re-transferred to the liquid storage device to ensure the purity and stability of the liquid. At the same time, the remaining liquid is re-transferred to the liquid storage device to avoid liquid waste. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] The present invention will be further described below in conjunction with the embodiments.

[0037] Example: Refer to Figures 1 to 14 , a pressing and bending device for door and window processing, comprising: A base 1, both sides of the upper end surface of the base 1 are fixedly connected with electric threaded rods 13, and the inner bottom of the base 1 is fixedly connected with a control box 11; The clamping mechanism 2 includes two sliders 21 horizontally slidably connected to both sides of the base 1, and the sliders 21 are threadedly connected to the rod body of the electric threaded rod 13 through a threaded block. The upper end surfaces of the two sliders 21 are each provided with a positioning assembly 22. The side of the positioning assembly 22 away from the electric threaded rod 13 is sequentially provided with a clamping block 23, an adjustment assembly 24 and a stabilizing assembly 25 from the inside to the outside. The opposite surfaces of the two positioning assemblies 22 and the clamping block 23 are each provided with a deformation assembly 26, and a door and window frame strip 100 is clamped between the two deformation assemblies 26; The liquid injection mechanism 3 includes two connecting components 31 arranged on both sides of the base 1. A liquid storage device 35 is fixedly connected to the center position of the control box 11 facing the slider 21. The control box 11 divides the side of the control box 11 into an output area and a reflux area by the liquid storage device 35, and the output area and the reflux area correspond to the positions of the two connecting components 31 respectively. The output area is provided with a two-position three-way valve 36, an air conveyor 37 and a gas-liquid stirring component 38 which are interconnected with one of the connecting components 31, and the reflux area is provided with an adjustable pressure relief valve 32, a one-way valve 33 and a degassing component 34 which are sequentially connected with the other connecting component 31.

[0038] The forward and reverse rotation of the electric threaded rod 13 is used to drive the slider 21 to slide in the base 1, and the slider 21 slides while also synchronously driving the movement of the positioning component 22. The positioning component 22 cooperates with the clamping block 23 to clamp the door and window frame strip 100, and the clamping strength of the clamping block 23 on the door and window frame strip 100 is adjusted by the adjustment component 24. The deformation component 26 located in the adjustment component 24 and the clamping block 23 contacts the two sides of the door and window frame strip 100 that are deformed (bent) when the adjustment component 24 and the clamping block 23 clamp the door and window frame strip 100, thereby providing a deformed door and window frame strip 100. It plays a supporting role and deforms accordingly with the deformation of the door and window frame strip 100 when it is bent. When the stabilizing component 25 adjusts the clamping block 23 through the adjusting component 24, it will cause corresponding pressure on the door and window frame strip 100 to prevent the door and window frame strip 100 from bending and detaching and absorbing the vibration force in the door and window frame strip 100. The liquid storage device 35 is connected through the corresponding connecting component 31 and the two-position three-way valve 36, the air conveyor 37, and the gas-liquid stirring component 38 in the output area to mix the liquid in the liquid storage device 35 with the compressed air to form gas-liquid, and continuously transport it to the door and window frame strip 100 before bending.

The fixed block 221 in the positioning component 22 changes the distance between the clamping block 23 and the fixed block 221 by means of the clamping blocks 23 mounted at its four corners, thereby achieving the clamping of door and window frame strips 100 of different specifications by the clamping block 23 in cooperation with the fixed block 221.

The gas and liquid discharged from the holes of the porous drainage block 343 will be in a jet state, thereby realizing the separation of gas and liquid in the gas and liquid.

[0052] Reference Figure 8 , Figure 13 to Figure 14 , the two-position three-way valve 36 and the air conveyor 37 are fixedly connected in the output area, and the two-position three-way valve 36 is electrically connected to the controller, the other end of the transmission pipe 316 located in the output area is connected to the output end of the two-position three-way valve 36, and the output end of the air conveyor 37 is fixedly connected to the gas transmission pipe 371; The gas-liquid stirring assembly 38 includes a stirring box 381 fixedly connected to the output area, and the other end of the gas transmission pipe 371 is connected to one side of the stirring box 381, and the two sides of the stirring box 381 are respectively fixedly connected with a conduit 3811 and a delivery pipe 3812, the other side of the delivery pipe 3812 is fixedly connected to the output end of the liquid storage device 35, and the other side of the conduit 3811 is fixedly connected to one of the input ends of the two-position three-way valve 36; A motor 382 is installed on the other side of the mixing box 381. A rotating shaft 385 is rotatably connected inside the mixing box 381. Eccentric stirring wheels 383 are fixedly connected on both sides of the rotating shaft 385. A plurality of connecting rods 384 are fixedly connected to the edge ring array between the two eccentric stirring wheels 383. The output end of the motor 382 passes through the mixing box 381 and is fixedly connected to the rotating shaft 385.

[0053] It also includes an air flow regulator 4, which is fixedly connected to the side of the control box 11 away from the injection mechanism 3. The output end of the air flow regulator 4 is fixedly connected to an air supply pipe 41, and the other side of the air supply pipe 41 is fixedly connected to the other input end of the two-position three-way valve 36.

[0054] When the two-position three-way valve 36 is used to transport gas and liquid into the door and window frame strip 100 through the connecting component 31 of the output area, the two-position three-way valve 36 connects the conduit 3811 with the transmission pipe 316, and the gas-liquid stirring component 38 drives the rotating shaft 385 inside the stirring box 381 to rotate through the motor 382, ​​thereby driving the eccentric stirring wheel 383 and the connecting rod 384 to rotate, so as to complete the mixing of the gas and the gas transmitted by the air conveyor 37.

[0055] The working principle of the present invention is as follows: Step 1: First, the operator selects a suitable mold from a variety of bending molds 12 according to the specific size and bending requirements of the door and window frame strip 100, and modularly installs it on the upper end surface of the base 1, and then places the door and window frame strip 100 to be bent between the fixing block 221 and the clamping block 23. At this time, the door and window frame strip 100 is located within the working range of the clamping mechanism 2, preparing for subsequent processing; Then the operator turns the handle 243 forward. When the handle 243 rotates, the handle 243 rotates and moves along the shaft of the spiral rod 242. The moving handle 243 drives the linkage block 241 to move in the direction close to the clamping block 23. The movement of the linkage block 241 compresses the telescopic rod 222, causing the clamping block 23 to slide on the shaft of the telescopic rod 222 toward the fixed block 221, thereby shortening the distance between the fixed block 221 and the clamping block 23 and squeezing the elastic block 223, thereby storing elastic potential energy. As the distance is shortened, the door and window frame strip 100 located between the fixed block 221 and the clamping block 23 is clamped until the handle 243 cannot rotate in the forward direction, indicating that the moving clamping block 23 cooperates with the fixed block 221 to complete the clamping and fixing of the door and window frame strip 100. When the handle 243 is reversed, the elastic block 223 loses the squeezing force, and the elastic block 223 returns to a normal state. Then, the fixed block 221 and the clamping block 23 are gradually separated under the action of the elastic block 223, and the distance between the fixed block 221 and the clamping block 23 is also enlarged, so as to be used to remove the bent door and window frame strip 100.

[0056] Among them, in the process of the clamping block 23 moving and engaging, the airbag 251 between the linkage block 241 and the clamping block 23 is squeezed, and the viscous fluid (such as silicone oil, hydraulic oil, etc.) stored in the airbag 251 is collected into the elastic telescopic box 253 through the three-way pipe 252 under the action of pressure. The elastic telescopic box 253 extends due to the injection of the fluid, and the extended elastic telescopic box 253 contacts the door and window frame strip 100 and applies additional pressure to the door and window frame strip 100, which not only increases the clamping force of the fixed block 221 and the clamping block 23 on the door and window frame strip 100, but also uses the viscous fluid transported in the elastic telescopic box 253 to absorb and buffer the vibration of the door and window frame strip 100 during the clamping process, so that the fixed block 221 and the clamping block 23 clamp the door and window frame strip 100 more stably.

[0057] Special note: When the handle 243 is reversed and the distance between the fixed block 221 and the clamping block 23 becomes larger, the linkage block 241 and the clamping block 23 will no longer squeeze the airbag 251. Since the airbag 251 is made of elastic material, it has elastic memory characteristics. When squeezed by the linkage block 241 and the clamping block 23, the airbag 251 undergoes elastic deformation and stores elastic potential energy. When the squeezing force disappears, according to Hooke's law, the elastic material will try to restore to its original shape and volume under the drive of the elastic potential energy, just like a compressed spring that will automatically bounce back to its original shape after the external force is removed. The airbag 251 shrinks by its own elastic restoring force, and then returns the viscous fluid transported to the elastic telescopic box 253 to the airbag 251. While the fixing block 221 and the clamping block 23 complete the clamping of the door and window frame strip 100, the rubber strip 262 in the deformation assembly 26 respectively located in the fixing block 221 and the clamping block 23 closely fits the surface of the door and window frame strip 100, which, on the one hand, increases the friction with the door and window frame strip 100 to prevent it from sliding during the clamping process; on the other hand, the rubber strip 262 has a certain elasticity and can absorb part of the vibration energy generated when the door and window frame strip 100 is bent, and the deformation strip 263 is deformed accordingly according to the bending degree of the door and window frame strip 100, thereby providing support for the door and window frame strip 100, dispersing the bending stress, and reducing the risk of cracks or deformation of the door and window frame strip 100 due to stress concentration.

[0058] Step 2: As the clamping mechanism 2 completes clamping the door and window frame strip 100, the operator picks up the sleeve frames 312 located in the output area and the return area respectively, and sleeves them on the door and window frame strip 100 openings located in the output area and the return area, and the door and window frame strip 100 openings in the output area and the return area will be in airtight contact with the multi-grid sealing ring 314 inside the sleeve frame 312 (the multi-grid sealing ring 314 is composed of a plurality of sealing rings of different specifications corresponding to the door and window frame strip 100 standard), effectively preventing gas and liquid from leaking during the transportation and output process; The fixing structure 315 around the sleeve frame 312 plays a fixing role to prevent the sleeve frame 312 from being separated from the opening position of the door and window frame strip 100. At this time, the operator rotates the knob 3156 in the forward direction. Since the spiral telescopic rod 3155 is composed of a threaded rod and a threaded sleeve, when the knob 3156 is rotated in the forward direction, the threaded rod rotates and extends outside the threaded sleeve, thereby driving the first slide plate 3152 to slide in the connecting frame 3151 toward the door and window frame strip 100. The first slide plate 3152 faces the inner side of the sleeve frame 312. A rubber plate 3153 is fixedly connected to one side of the door and window frame strip 100. When the first slide plate 3152 approaches the door and window frame strip 100, the rubber plate 3153 squeezes the door and window frame strip 100, so that the sleeve frame 312 clamps and fixes the two ends of the door and window frame strip 100. At the same time, the first spring 3154 on the opposite side of the first slide plate 3152 inside the connecting frame 3151 plays a buffering and regulating role to avoid excessive clamping force that damages the door and window frame strip 100, so as to complete the sleeve fixation of the sleeve frame 312 on the opening of the door and window frame strip 100.

[0059] Similarly, when the operator reverses the knob 3156 to rotate the threaded rod of the spiral telescopic rod 3155 into the threaded sleeve, the threaded sleeve drives the first slide plate 3152 to retract into the connecting frame 3151 to release the sleeve frame 312 from being fixed to the opening of the door and window frame strip 100.

[0060] Among them, when the operator completes the sleeve fixing of the openings on both sides of the door and window frame strip 100 of the sleeve frame 312, the operator usually controls the liquid storage device 35 to start, and the liquid storage device 35 is composed of a pump body and a liquid storage box. Therefore, when the liquid storage device 35 is started, the pump body will transport the liquid (such as water-based cutting fluid) stored in the liquid storage box to the mixing box 381 through the delivery pipe 3812. When the liquid storage device 35 is started, the air conveyor 37 is also started synchronously. The air conveyor 37 uses a fan to inhale and filter the outside air, and then transports it to the mixing box 381 of the gas-liquid mixing component 38 through the gas transmission pipe 371; While the air conveyor 37 and the liquid storage device 35 are started to convey air and liquid into the mixing box 381, the motor 382 installed on the side of the mixing box 381 is also started synchronously, and the output shaft of the motor 382 drives the rotating shaft 385 to rotate, and the eccentric stirring wheels 383 fixedly connected on both sides of the shaft body of the rotating shaft 385 and the connecting rods 384 of the annular array between the two eccentric stirring wheels 383 rotate accordingly. The eccentric structure of the eccentric stirring wheel 383 causes it to produce a strong stirring effect on the compressed gas and liquid in the box when it rotates. The connecting rod 384 further enhances the stirring effect, so that the gas and liquid are fully contacted and mixed to form a stable gas-liquid mixture (hereinafter referred to as gas-liquid). When the gas-liquid stirring assembly 38 stirs the gas and liquid, the two-position three-way valve 36 is in state A (the two-position three-way valve 36 has three connection states A, B, and C, and the specific connection state description is described in the fourth step).

[0061] Step 3: After the gas-liquid stirring assembly 38 fully mixes the compressed gas and the liquid, the resulting gas-liquid is transported to the two-position three-way valve 36 through the conduit 3811 (the two-position three-way valve 36 is in state B at this time), and then transported to the transmission pipe 316 of the output area through the two-position three-way valve 36 (the two-position three-way valve 36 is in state B at this time), and the transmission pipe 316 further transports the gas-liquid to the corresponding sleeve frame 312 (the sleeve frame 312 here refers to the sleeve frame 312 corresponding to the output area), and finally transported to the door and window frame strip 100 , and the gas-liquid mixture enters the sleeve frame 312 through the transmission pipe 316, and is then injected into the door and window frame strip 100. During the injection process, the intelligent pressure gauge 313 on the side of the connecting component 31 monitors the pressure in the door and window frame strip 100 in real time, and feeds back the pressure data to the controller. When the gas and liquid fill the door and window frame strip 100, the pressure in the door and window frame strip 100 also reaches the maximum value. At this time, the controller controls the two-position three-way valve 36 to close, stop the gas-liquid injection, and avoid damage to the door and window frame strip 100 caused by excessive pressure.

[0062] Among them, when the controller completes the gas and liquid delivery to the door and window frame strip 100, the operator starts the electric threaded rod 13 through the controller. After the electric threaded rod 13 is energized, its motor drives the screw to rotate. Since the slider 21 is threadedly connected to the electric threaded rod 13 through the threaded block, the rotation of the screw is converted into a horizontal linear motion of the slider 21 on the base 1, so that the movement of the slider 21 drives the positioning assembly 22 to move synchronously on the base 1, so that the clamping mechanism 2 as a whole is close to the bending mold 12, and then as the electric threaded rod 13 continuously drives the clamping mechanism 2 to approach the bending mold 12, the bending mold 12 bends the door and window frame strip 100 clamped therein.

[0063] When the door and window frame strip 100 is bent by the bending die 12, as the door and window frame strip 100 is gradually bent under the action of the bending die 12, the gas-liquid pressure inside the door and window frame strip 100 increases. When the pressure exceeds a certain threshold, the gas and liquid in the door and window frame strip 100 are discharged through the middle sleeve frame 312 and the transmission pipe 316 of the reflux zone connecting component 31, and first enter the one-way valve 33 (the one-way valve 33 has two connecting states A and B. The specific connecting state is described in the fourth step, and the one-way valve 33 is in state B at this time), and then flows into the adjustable pressure relief valve 32 through the inlet pipe 321. The adjustable pressure relief valve 32 will reduce the pressure of the gas and liquid according to the bending angle and internal pressure of the door and window frame strip 100. The compressed gas and liquid enter the elastic part of the air relief component 34 through the pressure relief pipe 322. The liquid is then ejected from the holes of the porous drainage block 343 through the elastic tube 342. During the ejection process, due to the difference in physical properties between the gas and the liquid, gas-liquid separation is achieved. The liquid falls to the bottom of the air release box 341 due to gravity, and the gas is captured by the gas collecting cover 3465 at the bottom of the second slide 3461, so that the second slide 3461 slides up and down under the action of the second spring 3462. The first elastic rod 344 and the counterweight ball 3464 consume the energy of the gas during the up and down movement of the second slide 3461. After the energy is consumed, the gas is discharged into the space above the second slide 3461 of the air release box 341 through the air hole 3466 and is completely discharged from the exhaust valve 345. The separated liquid returns to the liquid storage device 35 through the air release tube 3412 to achieve the recycling of the liquid.

[0064] It should be noted that the one-way valve 33 is in state A when the gas and liquid are transported into the door and window frame strip 100 .

[0065] When the bending mold 12 bends the door and window frame strip 100 and the gas and liquid are discharged, the air flow regulator 4 is started, and the air flow regulator 4 uses the gas delivery pipe 41 to deliver gas to the sleeve frame 312 through the two-position three-way valve 36 (the two-position three-way valve 36 is in state C at this time) to the transmission pipe 316 of the output area, so as to achieve smooth gas and liquid discharge; At the same time, it also detects whether the bent door and window frame strips 100 have cracks that affect use. The gas delivered by the air flow regulator 4 can detect whether the bent door and window frame strips 100 have cracks that affect use. This is because when the door and window frame strips 100 are bent normally, the internal air pressure will gradually increase with the degree of bending. The gas delivered by the air flow regulator 4 will cause the air pressure to fluctuate within a certain range and be in a normal change trend; but if the door and window frame strips 100 have cracks, the gas will leak through the cracks, causing the internal air pressure to drop and no longer follow the normal rising law. The intelligent pressure gauge 313 monitors the abnormality of the air pressure change direction in real time, and feeds back the data to the controller, thereby determining whether the door and window frame strips 100 have cracks that affect use.

[0066] Step 4: 1) Three states of the two-position three-way valve 36 are described (the two-position three-way valve 36 has two input ends and one output end): A: All ports of the two-position three-way valve 36 are closed; B: The input end of the two-position three-way valve 36 connected to the conduit 3811 is opened, so that the input end connected to the conduit 3811 is connected to the output end, and the input end connected to the gas delivery pipe 41 is closed; C: The input end of the two-position three-way valve 36 connected to the gas pipe 41 is opened, thereby connecting the input end of the gas pipe 41 to the output end, and the input end connected to the conduit 3811 is closed.

[0067] 2) Three states of the one-way valve 33 are described (the one-way valve 33 has an input end and an output end): A: All ports of the one-way valve 33 are closed; B: Both the input and output ends of the one-way valve 33 are open.
