[0002] During the production and forging process of forklift front forks, the front forks may be bent due to various factors, which seriously affects the quality and performance of the front forks. Therefore, after forging, the front forks must be straightened to ensure that they meet the production standards. During the straightening process, the operator will place the calcined front forks on a chain plate that can have a conveying function, and then use the straightening frame and the opposite contact frame to squeeze both sides of the bent part of the front fork at the same time, so as to straighten the bent part of the front fork.

The two levers 74 on the same group of support arms 71 form a group, and the two levers 74 in each group are symmetrically arranged. The two groups of levers 74 are symmetrically arranged, and the lower sliding grooves of the four levers 74 are respectively slidably connected to the four connecting columns 72, and a sliding frame 75 is slidably connected between the two guide frames 73 in each group.

[0038] It also includes a contact frame 76, and the two contact frames 76 are rotatably connected to the ends of the two sliding frames 75 that are close to each other. The two contact frames 76 are symmetrically arranged, and the contact frames 76 are U-shaped structures. The U-shaped contact frames 76 are used to adapt to the curvature of the front fork 5.

[0039] The flipping mechanism includes a guide rod 81, and the two guide rods 81 are connected to the middle part of the frame 1 by bolts. The two guide rods 81 are symmetrically arranged, and a moving frame 82 is slidably connected between the two guide rods 81. Both ends of the moving frame 82 are rotatably connected with a rotating frame 83, and the two rotating frames 83 are symmetrically arranged. The two rotating frames 83 are used to drive the front fork 5 to flip, and the two guide rods 81 are connected to a rack 84 by bolts. The two racks 84 are symmetrically arranged, and the rotating shafts of the two rotating frames 83 are connected to gears 85 through key slots. The middle part of the frame 1 is connected to a third hydraulic rod 86 by bolts, and the telescopic rod of the third hydraulic rod 86 is connected to the middle part of the moving frame 82 by bolts.

[0040] It also includes support bars 87 , and two of the support bars 87 are respectively connected to the two ends of the mobile frame 82 by bolts, and the two support bars 87 are symmetrically arranged. The two support bars 87 are respectively in contact with the rotating frame 83 , and the support bars 87 are used to limit the rotating frame 83 .

[0041] It also includes a high-frequency heating coil 11 . The two high-frequency heating coils 11 are respectively connected to the two rotating frames 83 . The high-frequency heating coils 11 are used to heat the front fork 5 .

[0042] Initially, the support bar 87 is against the bottom of the rotating frame 83 so that the rotating frame 83 is in an upright state. First, the operator heats the front fork 5 to be straightened and places it on the chain plate 4. Then the operator controls the output shaft of the reduction motor 2 to rotate. The rotation of the output shaft of the reduction motor 2 drives the chain plate 4 to rotate through the roller 3. The chain plate 4 moves the part of the front fork 5 that needs to be straightened to the middle of the frame 1 and then turns off the reduction motor 2. At the same time, the front fork 5 passes through the two rotating frames 83. When the bent part of the front fork 5 is in the same direction as the first hydraulic rod 63, the operator controls the extension of the second hydraulic rod 64. The extension of the retracting rod and the retraction of the telescopic rod of the first hydraulic rod 63 cause one end of the straightening frame 62 to move toward the curved part of the front fork 5, and then one end of the straightening frame 62 will squeeze one side of the curved part of the front fork 5. At the same time, the movement of the straightening frame 62 will drive the two groups of connecting columns 72 to move together. The movement of the two groups of connecting columns 72 will respectively drive the two sliding frames 75 to move in opposite directions through the two groups of levers 74. The movement of the two sliding frames 75 will respectively drive the two contact frames 76 to move, and then one of the contact frames 76 will squeeze the other side of the curved part of the front fork 5. At the same time, the contact frames 76 of the U-shaped structure 76 will rotate according to the curvature of the front fork 5 so that both ends of the contact frame 76 are in contact with the surface of the front fork 5, so that the two ends of the contact frame 76 can better squeeze the front fork 5. In this way, the straightening frame 62 squeezes the front fork 5 and squeezes the other side of the front fork 5 from the opposite direction through the opposite contact frame 76, so as to straighten the bent part of the front fork 5. After the bent part of the front fork 5 is straightened, the operator controls the first hydraulic rod 63 and the second hydraulic rod 64 to reset, so that the straightening frame 62 is reset, and the reset of the straightening frame 62 drives the lever 74 to reset through the connecting column 72 , the reset of the lever 74 will drive the contact frame 76 to reset through the sliding frame 75. When the remaining parts of the front fork 5 need to be straightened, the operator controls the chain plate 4 through the reduction motor 2 to move the remaining bent parts of the front fork 5 to the middle of the frame 1, and then continues to control the first hydraulic rod 63 and the second hydraulic rod 64 to drive the straightening frame 62 to move and straighten the bent parts of the front fork 5, thereby straightening multiple bent parts of the front fork 5, so that the straightening frame 62 and the contact frame 76 can quickly straighten multiple bent parts of the front fork 5, thereby improving the straightening efficiency of the bent parts of the front fork 5;When it is necessary to straighten the upper and lower sides of the front fork 5, the telescopic rod of the third hydraulic rod 86 is extended to drive the moving frame 82 to move away from the third hydraulic rod 86. The movement of the moving frame 82 will drive the two rotating frames 83 to move together. The movement of the two rotating frames 83 will drive the front fork 5 to move. The movement of the two rotating frames 83 will drive the two gears 85 to move together. During the movement of the two gears 85, they will respectively mesh with the two racks 84, so that the two racks 84 respectively drive the two rotating frames 83 to rotate in the direction of the third hydraulic rod 86 through the two gears 85. At the same time, the support bar 87 no longer resists the bottom of the rotating frame 83. After the two rotating frames 83 rotate ninety degrees, they will be respectively resisted by the two support bars 87. When the rotating frame 83 rotates 90 degrees, the front fork 5 will be driven to rotate 90 degrees. In this way, the rotating frame 83 moves and drives the front fork 5 to rotate 90 degrees through the gear 85 and the rack 84 to flip the front fork 5, so that the straightening frame 62 and the contact frame 76 can straighten the upper and lower sides of the front fork 5, so that the straightening position of the front fork 5 is more comprehensive, thereby further improving the straightening efficiency of the bent part of the front fork 5. When the temperature of the front fork 5 drops and the ductility becomes poor, the operator heats the part that needs to be straightened through the two high-frequency heating coils 11, which is conducive to straightening the bent part of the front fork 5. After the straightening of the front fork 5 is completed, the operator controls the reduction motor 2 to rotate the chain plate 4 to transport the front fork 5 to the next process. ;

[0043] Embodiment 2: Based on embodiment 1, Figure 1-Figure 12As shown, it also includes a pressing mechanism, which is arranged on the guide frame 73, and is used to limit the front fork 5 from the top. The pressing mechanism includes a limiting frame 91, and the two limiting frames 91 are rotatably connected to the two guide frames 73 on the same axis respectively. The two limiting frames 91 are used to limit the front fork 5, and both ends of the two limiting frames 91 are connected with space cams 92 through key grooves, and the space cams 92 are provided with guide grooves. The two space cams 92 at the same end of the two limiting frames 91 are a group, and the two space cams 92 in each group are symmetrically arranged. The two groups of space cams 92 are symmetrically arranged, and the middle parts of the four guide frames 73 are slidably connected with sliding rods 93, and the two sliding rods 93 on each group of guide frames 73 are a group, and the two sliding rods 93 in each group are symmetrically arranged. The slide bars 93 are symmetrically arranged, and the tops of the four guide frames 73 are slidably connected with guide arms 94. The two guide arms 94 on each group of the guide frames 73 form a group, and the two guide arms 94 in each group are symmetrically arranged. The two groups of guide arms 94 are symmetrically arranged, and the guide arms 94 are used to drive the limit frame 91 to rotate through the space cam 92. The middle parts of the four guide arms 94 are respectively slidably connected to the four slide bars 93, and tension springs 95 are respectively connected between the four guide arms 94 and the slide bars 93. The four guide arms 94 are respectively connected to the guide frames 73 with first pressure springs 96. The two groups of guide arms 94 are respectively slidably connected to the guide grooves of the two groups of space cams 92, and the ends of the two groups of slide bars 93 that are close to each other are respectively in contact with the tops of both sides of the two slide frames 75.

[0044] At first, the first pressure spring 96 presses against the guide arm 94, so that the guide arm 94 presses against the limit frame 91 through the space cam 92. When one of the sliding frames 75 moves in the direction away from the front fork 5, the top of the two sides of the sliding frame 75 will respectively squeeze the two sliding rods 93 on the same side to move in the direction away from the front fork 5. The movement of the two sliding rods 93 will respectively pull the two guide arms 94 on the same side to move through the tension spring 95. The two first pressure springs 96 on the same side are compressed, and the movement of the two guide arms 94 will respectively drive the limit frames 91 to rotate through the space cam 92. The rotation of the two limit frames 91 will press against the front fork 5 at the same time. In this way, the front fork 5 is not easily turned over due to squeezing during straightening, thereby making the front fork 5 The limit frame 91 stops rotating after it abuts against the front fork 5, so that the two guide arms 94 no longer move, and the slide bar 93 continues to move. The two tension springs 95 on the same side are stretched, and the two tension springs 95 continue to apply tension to the guide arms 94, so that the guide arms 94 continue to apply a torsional force to the limit frame 91 through the space cam 92. When the sliding frame 75 is reset, the two slide bars 93 will no longer be squeezed, so that the two slide bars 93 will no longer hold the two guide arms 94 through the two tension springs 95. The two first pressure springs 96 are reset to drive the two guide arms 94 to reset, and the tension spring 95 is reset to drive the slide bar 93 to reset. At the same time, the reset of the guide arms 94 will return the limit frame 91 to its initial state through the space cam 92.

[0045] Embodiment 3: Based on embodiment 2, Figure 1-Figure 14 As shown, it also includes a straightening mechanism, which is arranged on the frame 1 and is used to straighten the front fork 5. The straightening mechanism includes a support beam 101, which is connected to the top of the frame 1 by bolts, and the bottom of the support beam 101 is rotatably connected to two rotating frames 102, and the two rotating frames 102 are centrally symmetrically arranged. The two rotating frames 102 are used to squeeze the front fork 5, and the tops of both ends of the straightening frame 62 are connected to guide sleeves 103 by bolts, and the two guide sleeves 103 are symmetrically arranged. An extrusion frame 104 is slidably connected, and the two extrusion frames 104 are centrally symmetrically arranged. The ends of the two extrusion frames 104 that are close to each other are V-shaped structures. The V-shaped structures of the extrusion frames 104 are used to respectively resist the two rotating frames 102. The V-shaped structures of the two extrusion frames 104 are respectively in contact with the two sides of the two rotating frames 102. The second pressure spring 105 is connected between the V-shaped structures of the two extrusion frames 104 and the two guide sleeves 103 respectively. The guide sleeve 103 is used to push the extrusion frame 104 to move through the second pressure spring 105.

[0046] When one end of the straightening frame 62 moves toward the front fork 5, it will drive the guide sleeve 103 on the same side to move. The movement of the guide sleeve 103 will push the extrusion frame 104 through the second pressure spring 105, so that the extrusion frame 104 on the same side moves toward the direction close to the front fork 5. At the same time, the V-shaped structure of the extrusion frame 104 will squeeze the two rotating frames 102 at the same time, so that the two rotating frames 102 will rotate at the same angle and clamp the two ends of the front fork 5. The straightening frame 62 drives the guide sleeve 103 to continue to move, and the second pressure spring 105 on the same side is compressed, so that the second pressure spring 105 The squeezing frame 104 continuously applies pressure to the two rotating frames 102, so that the rotating frame 102 continuously squeezes the front fork 5, and then moves the front fork 5 to the middle position of the frame 1, so that the front fork 5 is subjected to more uniform force during the straightening process, thereby further enhancing the straightening effect on the bent part of the front fork 5. When the straightening frame 62 is reset, the guide sleeve 103 is driven to reset. When the guide sleeve 103 is reset, the squeezing frame 104 is no longer squeezed by the second pressure spring 105. The second pressure spring 105 is reset, and at the same time, the reset of the guide sleeve 103 pulls the squeezing frame 104 to reset.

[0047] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
