Detailed Implementation

[0026] like Figures 1 to 5 As shown:

[0027] A processing machine tool includes a crossbeam 101, two arc-shaped frames 102 symmetrically fixed on the crossbeam 101, and a rotatable fixing component connecting the crossbeam 101 and the two arc-shaped racks 103. A slide 104 is connected to the crossbeam 101, a rod 105 is fixed on the slide 104, and an intermediate rod 106 is fixed on the rod 105.

[0028] The two ends of the part to be bent are clamped and fixed to two fasteners. The inner ends of the two fasteners are rotatably connected to the crossbeam 101. The two fasteners can rotate on the two arc-shaped frames 102 around the axis of the rotatable connection with the crossbeam 101. The front side of the part to be bent is in contact with the middle rod 106. When the two fasteners rotate towards each other at the same time, the two ends of the part are driven to move closer to each other and bend around the middle rod 106, which serves as a support. By controlling the rotation angle of the two fasteners, the part can be bent around the middle rod 106 to different angles, thereby changing the shape of the bent part.

[0029] like Figure 4 As shown:

[0030] The slide block 104 is slidably connected to the crossbeam 101, and an electric push rod I 107 is fixedly connected to the slide block 104. The telescopic end of the electric push rod I 107 is fixedly connected to the crossbeam 101.

[0031] The electric push rod I 107 extends or retracts, causing the slide 104 to move back and forth. The slide 104 causes the rod frame 105 and the intermediate rod 106 to move back and forth, thereby enabling the intermediate rod 106 to fit onto pipes of different diameters or parts of different thicknesses, so that when the part is bent, it can be stably bent around the intermediate rod 106.

[0032] like Figure 6 and 7 As shown:

[0033] Two side rods 203 are symmetrically arranged on the front side of the middle rod 106 on the rod frame 105;

[0034] The intermediate rod 106 is located at the rear end of the two side rods 203 and contacts the end face of the part. When the part bends around the intermediate rod 106 until both ends of the part contact the two side rods 203, the bending is completed. At this time, the angle formed by the line connecting the center of the cross-section of the two side rods 203 and the intermediate rod 106 is the angle formed after the part is bent. Therefore, the angle formed after the part is bent can be determined by measuring the angle between the intermediate rod 106 and the two side rods 203 in advance.

[0035] like Figures 5 to 7 As shown:

[0036] A guide rod 108 is fixedly connected to the frame 105, and two side rods 203 are slidably connected to the two ends of the guide rod 108 respectively;

[0037] A slide block 201 is slidably connected to the rod frame 105, and two hinged arms 202 are hinged to the slide block 201. The two hinged arms 202 are rotatably connected to two side rods 203 respectively.

[0038] A drive motor is fixedly connected to the slide 104, and a lead screw 109 is connected to the output shaft of the drive motor through a coupling. The slide 201 and the lead screw 109 are threadedly connected.

[0039] The drive motor starts and drives the lead screw 109 to rotate. The lead screw 109 drives the slide 201 to move back and forth. The slide 201 drives the two hinge arms 202 to move. The hinge arms 202 drive the two side rods 203 to move closer to each other or further away on the guide rod 108. When the two side rods 203 move further away from each other, the distance between the two side rods 203 increases. After the part rotates around the middle rod 106 and comes into contact with the two side rods 203 with a larger distance, the shape of the part at the bend tends to be an arc surface. When the two side rods 203 move closer to each other, the bend surface of the part after bending around the middle rod 106 tends to be an acute angle. Therefore, by adjusting the distance between the two side rods 203, the shape formed at the bend of the part can be changed. The larger the distance between the two side rods 203, the greater the curvature of the arc surface at the bend. The smaller the distance between the two side rods 203, the clearer the angle of the acute angle formed at the bend.

[0040] like Figures 8 to 10 As shown:

[0041] The fixing component includes a rotating frame 301 rotatably connected to the crossbeam 101. A T-shaped seat 302 is fixedly connected to the outer end of the rotating frame 301. The T-shaped seat 302 is slidably connected inside the arc frame 102. Two clamping plates 304 are symmetrically slidably connected to the T-shaped seat 302. A bidirectional screw 303 is rotatably connected to the T-shaped seat 302. The two clamping plates 304 are respectively threaded to the two ends of the bidirectional screw 303.

[0042] When both ends of the part are flat, the ends of the part can be placed between the two clamping plates 304. Rotating the bidirectional screw 303 will cause the two clamping plates 304 to move closer to each other and clamp the parts on the vertical ends of both sides, thus clamping and fixing the parts. The two clamping plates 304 are convenient for clamping and fixing sheet-like or square tube-shaped parts.

[0043] like Figures 11 to 13 As shown:

[0044] The fastener also includes a side frame 305 fixed to the clamping plate 304, and a V-shaped plate frame 307 is inserted into the side frame 305.

[0045] An electric push rod II 306 is fixedly connected to the side frame 305, and the telescopic end of the electric push rod II 306 is fixedly connected to the V-shaped plate frame 307.

[0046] When it is necessary to clamp tubular parts, the electric push rod II 306 is activated to drive the V-shaped plate frame 307 to extend out of the clamping plate 304, so that the tubular parts can be placed between the two V-shaped plate frames 307 that are arranged opposite each other. Then, the bidirectional screw 303 is rotated to drive the two V-shaped plate frames 307 to move closer to each other to clamp and fix the tubular parts. This makes the device suitable for clamping, fixing and bending parts of different shapes.

[0047] like Figure 3 and 9 As shown:

[0048] Arc-shaped racks 103 are fixedly connected to both arc-shaped frames 102, and geared motors 308 are fixedly connected to both rotating frames 301. Gears 309 are fixedly connected to the output ends of both geared motors 308, and the two gears 309 are respectively meshed with the two arc-shaped racks 103 for transmission.

[0049] The two geared motors 308 are started simultaneously to drive the two gears 309 to rotate. The two gears 309 are connected to the two arc racks 103 through meshing transmission, which drives the two rotating frames 301 to rotate around the axis of the rotating connection between the rotating frame 301 and the crossbeam 101. The two rotating frames 301 drive the two T-shaped seats 302 to slide closer to each other within the two arc frames 102. The two T-shaped seats 302 drive the two ends of the clamped parts to bend closer to each other through the two clamping plates 304 or the two V-shaped plate frames 307 on them.
