[0015] The present invention is further described below in conjunction with the accompanying drawings and embodiments:

[0016] like Figure 1 , Figure 2 , Figure 3As shown in the embodiment, the sheet metal bending flow processing device is a device that can soften the workpiece by heating, and then bend the sheet metal by conveying and extruding to realize automated sheet metal processing, which includes a conveying module 1, a bending module 2 and a heating module 3; the conveying module 1 includes a chain plate mounted on a support frame, the chain plate is connected to a transmission structure through a sprocket, the chain plate is wound on the sprocket to form an upper and lower side, and a support plate 13 is mounted on the lower part of the upper chain plate; a push plate 11 is fixed on the outer surface of the chain plate; the workpiece 4 to be processed is placed in front of the push plate 11, and the left end of the support plate 13 is designed with a The limiting plate 12; the right end of the conveying module 1 is provided with a heating module 3, and the heating parts of the heating module 3 are arranged on the upper and lower sides of the workpiece 4; the front of the heating module 3 is designed with a bending module 2, and the bending module 2 includes a horizontal fixing rod 21 fixedly installed on the right side of the conveying module 1; the fixing rod 21 is axially arranged and connected with guide rollers 22, and an angle is designed between adjacent guide rollers 22, and the degree of the angle is less than 5°; the angle between the guide rollers 22 and the horizontal plane is arranged in sequence from small to large on the fixing rod 21 in a back-to-front order, that is, from back to front along the upper chain plate (i.e. Figure 1 The angle between each guide roller (from left to right) and the horizontal plane changes evenly from a horizontal state of 0° to the angle at which the workpiece needs to be bent. In this embodiment, the end guide roller 22 is in a vertical state of 90° with the horizontal plane, so that the plate-like workpiece 4 can be bent into 90 degrees. The guide roller 22 is connected to the fixed rod 21 through a linear connecting shaft, and the guide roller 22 can be self-rotatingly assembled relative to the linear connecting shaft. In this way, when the plate-like workpiece 4 moves to the guide roller 22, rolling friction occurs between the workpiece 4 and the guide roller 22, so that the surface of the workpiece is not easily worn. The bending module 2 includes a pressure rod 23 arranged in parallel with the fixed rod 21, and the pressure rod 23 is installed above the workpiece 4. The pressure roller contacts the upper end surface of the workpiece 4. A spacing is designed between the pressure rod 23 and the guide roller 22, and the minimum spacing between the pressure rod 23 and the guide roller 22 is consistent with the thickness of the workpiece 4.

[0017] When the sheet metal bending assembly line processing device is in use, the user places the workpiece in front of the push plate 11, and makes the left side of the workpiece contact with the right side of the limit plate 12, and the workpiece moves forward under the action of the push plate 11; when the right side of the workpiece enters the heating module 3, the right side of the workpiece is heated and softened under the action of the heating module 3, and the heated side is conveyed to the top of the bending module 2 under the push of the push plate 11; when the right side of the workpiece contacts the guide roller 22, the right side of the workpiece slides on the guide roller 22 and bends and deforms to the left under the pressing action of the limit plate 12; at the same time, the upper end of the workpiece is pressed by the pressure rod 23, so that the workpiece forms an angle under the pressure rod 23; in this process, the right side of the workpiece is continuously bent and deformed by the bending module 2 until the workpiece passes through the bending module 2 and is completely bent and deformed, thereby achieving the effect of automatic softening and bending.

[0018] For workpieces with different required bending angles, the user can manually adjust the angle between the guide rollers 22 to adjust the bending angle of the bending module 2, so that the bent workpiece can adapt to the needs of different bending angles.

[0019] like Figure 3 As shown, the heating module 3 includes a solenoid 31 and a bracket 32; the solenoid 31 is symmetrically fixed above and below the workpiece 4 through the bracket 32, and the axial direction of the solenoid 31 is perpendicular to the surface of the workpiece 4 to be heated; the solenoid 31 is connected to the same high-frequency AC power supply, and its function is: when the right side of the workpiece passes through the heating module 3, since the solenoid 31 is connected to the high-frequency AC power supply, the high-frequency AC power supply provides an alternating current to the solenoid 31, and the alternating current flowing through the solenoid 31 generates an alternating magnetic field passing through the workpiece 4, and the magnetic field generates eddy currents inside the workpiece 4, and induction heating occurs, thereby achieving the heating effect on the workpiece 4.

[0020] like Figure 1 , Figure 2 , Figure 3 As shown, the upper end of the pressure rod 23 is connected to an electric push rod that moves in its radial direction. Its function is: when the user needs to adjust the bending point of the workpiece 4, the user uses the electric push rod to make the pressure rod 23 move along its radial direction on the horizontal plane until it moves to the required bending point, and then locks the pressure rod 23; in this way, the bending point of the workpiece 4 during the bending period will be close to the bottom of the pressure rod 23, thereby achieving the function of adjusting the bending point.

[0021] like Figure 1 , Figure 3As shown, the output end of the conveying module 1 includes a cooling pool, and an ultrasonic cleaning device is installed in the cooling pool. Its function is: when the workpiece 4 is heated and bent, it falls into the cooling pool through the output end of the conveying module, and the coolant in the cooling pool cools the heated part of the workpiece 4 to accelerate the cooling and shaping of the workpiece 4; at the same time, the ultrasonic cleaning device in the cooling pool is started to clean the impurities generated on the surface of the workpiece 4 during the heating and bending process.

[0022] like Figure 1 , Figure 2 , Figure 3 As shown, the guide roller 22 and the pressure rod 23 are wrapped with a wrapping layer made of a heat-insulating material, and its function is as follows: when the workpiece 4 is heated by the heating module 3, the temperature of the heated part is relatively high, and when passing through the guide roller 22 and the pressure rod 23, they will be damaged by the high temperature, thereby affecting the bending accuracy of the workpiece 4, and the heat-insulating wrapping layer can effectively isolate the heat on the workpiece 4, so that the guide roller 22 and the pressure rod 23 can bend the workpiece 4 normally, and can extend their service life and reduce the cost of use.

[0023] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
