The workpiece can be limited by limiting groove one and limiting groove two. During the bending process of the workpiece by the pressure die, the workpiece will be held in limiting groove one and limiting groove two to achieve the purpose of limiting the workpiece.

[0003] However, during use, this device is not convenient for fixing bolts, which can easily cause bolt misalignment, resulting in reduced bolt production efficiency and processing speed, thus affecting the bolt yield. Utility Model Content

[0004] The purpose of this utility model is to provide a bending machine for producing U-bolts. By setting a fixing part, the problem of the device being inconvenient to fix the bolts during use, which easily causes the bolts to shift, resulting in reduced bolt production efficiency, reduced bolt processing speed, and affected bolt yield is solved.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a bending machine for producing U-bolts, comprising a base and a support frame fixedly connected to the bottom of the base, and further comprising: a fixing part disposed on the base; a bending part installed on the top of the base; the fixing part including a power component disposed at the bottom of the base; and a fixing assembly installed on the base; the power component including an electric telescopic rod fixedly connected to the inner rear wall of the support frame; a trapezoidal groove is provided at the bottom of the base; a bidirectional hinge block is provided at the bottom of the base; the top of the bidirectional hinge block extends into the trapezoidal groove; the bidirectional hinge block is slidably connected to the trapezoidal groove; the output shaft of the electric telescopic rod is fixedly connected to the bidirectional hinge block; and two hinge rods are hingedly disposed on the bidirectional hinge block; wherein, the electric telescopic rod is located at the bottom of the base, and the two hinge rods are located on the left and right sides of the bidirectional hinge block, respectively.

[0006] Furthermore, the bending portion includes a bending assembly mounted on top of the base; and a driving assembly disposed on the base; wherein the driving assembly is located between the bending assemblies.

[0007] Furthermore, the fixing assembly includes two limiting slide grooves formed on the base, each containing a slider slidably connected to it. A fixing rod is fixedly connected to the bottom of each slider. Two hinged rods are respectively hinged to the two fixing rods. A fixing plate is fixedly connected to the top of each slider. Anti-slip buffer pads are fixedly connected to the sides of the two fixing plates that are close to each other. The two limiting slide grooves are located on the left and right sides of the base, respectively, while the two sliders are located on the sides of the two limiting slide grooves that are far apart from each other. The fixing plates move the anti-slip buffer pads closer to or further apart, thus centering and loosening the bolts and preventing bolt misalignment.

[0008] Furthermore, the bending assembly includes a bending die fixedly connected to the top of the base. Several rectangular plates are fixedly connected to the top of the base, and two sliding rods are fixedly connected between the rectangular plates. A portal frame is slidably connected to the two sliding rods, and a bending component is mounted on the portal frame. Four rectangular plates are arranged in a mirror image. The two sliding rods are located above the bending die. The bending component includes two supports fixedly connected to the front side of the portal frame, and extrusion rollers are rotatably connected to each of the two supports. The two supports are located on the left and right sides of the portal frame, respectively, and the two extrusion rollers are located between the two supports. The sliding rods ensure smooth sliding of the portal frame, and the portal frame drives the extrusion rollers to move via the supports.

[0009] Furthermore, the drive assembly includes a fixed block fixedly connected to the top of the base, a hydraulic cylinder fixedly connected to the top of the fixed block, a drive block located on the front side of the fixed block, the output shaft of the hydraulic cylinder fixedly connected to the drive block, two drive rods hinged to the drive block, and a drive component mounted on the drive block; wherein the two drive rods are located on the left and right sides of the drive block respectively, and the drive component includes a hinge block one fixedly connected to two rectangular plates located on the rear side, two hinge blocks two fixedly connected to the rear side of the portal frame, two slotted plates hinged to each of the two drive rods, the two hinge blocks one respectively hinged to the two slotted plates located on the rear side, and the two hinge blocks two respectively hinged to the two slotted plates located on the rear side, providing power for the movement of the portal frame and ensuring that the extrusion wheel applies force to the bolt smoothly.

[0010] This utility model has the following beneficial effects: 1. By setting a fixing part, the bolt is placed between two anti-slip buffer pads. After the electric telescopic rod is started, it pushes the two-way hinge block to slide forward in the trapezoidal slide groove, which drives the two hinge rods to move forward. Then, through the fixing rod, the two sliders are brought closer to each other in the limiting slide groove. Finally, the fixing plate drives the anti-slip buffer pads to fix the bolt in the center. Reverse operation can make the anti-slip buffer pads move away from each other, ensuring that the fixing position is consistent each time, improving the efficiency of operation, preventing the bolt from shifting or sliding during subsequent bending processing, ensuring a stable fixation, and providing a guarantee for the smooth progress of processing.

[0011] 2. By setting up a bending section and activating the hydraulic cylinder, the drive block is moved forward, causing two drive rods to move and rotate on the drive block while moving away from each other. This, in turn, pushes two channel plates to move and rotate on corresponding hinge blocks one and two, reducing the angle between several channel plates. This allows the portal frame to slide smoothly on two parallel slide rods. The portal frame drives two extrusion rollers to move through the support. The extrusion rollers cooperate with the bending die during rotation to complete the bending of the bolts. This ensures that the portal frame remains stable during movement and does not tilt or wobble, thus guaranteeing the uniform force applied to the bolts by the extrusion rollers. This makes the bending process more stable and reliable, improves production efficiency, and reduces labor intensity.

[0012] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0020] A specific application of this embodiment is as follows: In use, the bolt is placed between the two anti-slip buffer pads 225, and then the electric telescopic rod 211 is activated. At this time, the electric telescopic rod 211 pushes the bidirectional hinge block 213 to slide forward in the trapezoidal slide groove 212.

At this time, the two hinge rods 214 respectively drive the two sliders 222 to slide in the corresponding limiting slide grooves 221 and move closer to each other through the two fixed rods 223. At this time, the two sliders 222 respectively drive the two anti-slip buffer pads 225 to move closer to each other through the two fixed plates 224 and fix the bolt in the center. Through the reverse operation process, the two fixed plates 224 respectively drive the two anti-slip buffer pads 225 to move away from each other. After the fixing is completed, the hydraulic cylinder 322 is activated. At this time, the hydraulic cylinder 322 pushes... The drive block 323 moves forward, causing the two drive rods 324 to move. This causes the two drive rods 324 to rotate on the drive block 323 and move away from each other. At this time, the two drive rods 324 push the corresponding two slotted plates 327 to move and rotate on the corresponding hinge block 1 325 and hinge block 2 326 respectively, causing the angle between several slotted plates 327 to decrease. This pushes the portal bracket 314 to slide on the two slide rods 313. Under the action of the parallel design of the two slide rods 313, the portal bracket 314 moves smoothly.

At this time, the two extrusion rollers 316 cooperate with the bending die 311 to bend the bolt.
