Technical Field

[0001] This invention relates to the field of bending and processing technology for steel accessories of power crossarms, specifically to a bending device for steel accessories of power crossarms. Background Technology

[0002] Crossarms are important steel accessories for transmission towers, mainly used to install insulators and electrical fittings, support conductors and lightning protection wires, and ensure the required electrical safety distance between lines. They are widely used in distribution networks and high-voltage overhead transmission projects. Crossarms are mostly made of angle steel, steel plates, and other profiles. Bending is a key process in the manufacturing of crossarm steel accessories. Through bending, the profiles are shaped into the required bending profiles to meet the structural requirements for crossarm assembly and installation.

[0015] Compared with the prior art, the present invention provides a bending device for electrical crossarm iron accessories, which has the following beneficial effects: This bending device for power crossarm iron accessories, through its positioning and adjustment mechanism, uses two first hydraulic rods to drive the sliding dies on a fixed rail for alignment and adjustment during use. This changes the distance between the two sliding dies, allowing them to be adjusted to a suitable distance according to the width of the steel plate. Therefore, no replacement is needed during use; only the distance between the sliding dies needs to be adjusted. After bending, the two sliding dies slide inwards, pushing the bent power crossarm iron accessory upwards, thus achieving automatic unloading. Simultaneously, a positioning component causes the two sliding seats to slide synchronously in opposite directions, pushing the sides of the steel plate towards the center with a positioning push plate, thereby positioning the steel plate and improving bending accuracy.

[0016] This bending device for the steel plate of the crossarm uses a punching and bending mechanism. During use, the bending die is driven by a second hydraulic rod to press down, so that the bending die and the sliding die can bend the steel plate into a right-angle structure.

[0017] This bending device for the crossarm steel accessory uses an oil spraying lubrication mechanism. During use, an oil pump draws bending oil from the oil tank and sprays it evenly onto both sides of the bending die through a nozzle, thereby lubricating the bending die and the steel plate and reducing wear on the bending die.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0022] Example 1: Please see Figures 1-6 The present invention provides a technical solution: a bending device for an electric crossarm iron accessory, including a frame 1, a housing 2 fixedly installed on the top of the frame 1, a control terminal 3 fixedly installed on the front of the housing 2, a positioning adjustment mechanism 4 provided inside the housing 2, a stamping bending mechanism 5 provided on the top of the frame 1, and an oil spraying lubrication mechanism 6 provided inside the stamping bending mechanism 5 and extending to the outside. The positioning adjustment mechanism 4 includes an adjustment component 41 and a positioning component 42. The adjustment component 41 is disposed inside the housing 2, and the positioning component 42 is disposed on the top of the housing 2. The adjustment assembly 41 includes a fixed base 411, which is fixedly installed on the top of the frame 1. A fixed rail 412 is fixedly installed on the top of the fixed base 411. A sliding mold 413 is slidably installed on the outside of the fixed rail 412. A baffle 414 is fixedly installed on the outer side of the top of the sliding mold 413. A first hydraulic rod 415 is fixedly installed on the fixed base 411. A placement groove 416 is provided at the connection between the baffle 414 and the sliding mold 413, so that the device can adjust the sliding mold 413 according to the width of the steel plate, thereby realizing the processing of power crossarm iron accessories of different sizes.

[0023] Furthermore, there are two of each of the first hydraulic rod 415, the sliding mold 413, and the baffle 414. The telescopic end of the first hydraulic rod 415 passes through the fixed base 411 and is fixedly installed on the outside of the sliding mold 413, so that the first hydraulic rod 415 can drive the sliding mold 413 to slide on the fixed rail 412.

[0024] Furthermore, a sliding groove is provided at the corresponding position of the housing 2 and the baffle 414, and the baffle 414 is slidably installed inside the sliding groove, so that the baffle 414 can be limited and slid inside the housing 2.

[0025] Furthermore, the sliding mold 413 is provided with a matching slot, and the two sliding molds 413 pass through the matching slot in an alternating manner, which facilitates the two sliding molds 413 to slide in an alternating manner.

[0026] Furthermore, the positioning component 42 includes a mounting frame 421, which is fixedly mounted on the top of the housing 2. A motor 422 is fixedly mounted on one side of the mounting frame 421, and a bidirectional screw 423 is fixedly mounted on the output end of the motor 422. A sliding seat 424 is slidably mounted inside the mounting frame 421, and a positioning push plate 425 is fixedly mounted on the front of the sliding seat 424 to facilitate the positioning and centering of the placed steel plate, thereby improving the bending processing accuracy.

[0027] Furthermore, there are two sliding seats 424 and two positioning push plates 425. The two sliding seats 424 are symmetrically threaded onto the outside of the two ends of the bidirectional screw 423 with opposite thread directions along the center line of the front of the mounting frame 421, so that the two sliding seats 424 can drive the positioning push plates 425 to slide synchronously in opposite directions.

[0028] In this embodiment, two first hydraulic rods 415 drive the sliding mold 413 to slide in opposite directions on the fixed rail 412, so that the distance between the two sliding molds 413 can be flexibly adjusted according to the width of the steel plate. It can adapt to different size processing requirements without changing the mold. The positioning component 42 drives the bidirectional screw 423 to rotate through the motor 422, so that the two sliding seats 424 drive the positioning push plate 425 to slide synchronously in opposite directions, pushing the steel plate from both sides to the center to achieve automatic centering positioning. After bending is completed, the two first hydraulic rods 415 drive the sliding mold 413 to slide inward again, pushing the bent workpiece upward along the mold slope to complete automatic unloading. This embodiment realizes three major functions: mold adjustment without replacement, automatic centering positioning of the workpiece, and automatic ejection and unloading after forming. It improves the versatility and ease of operation of the equipment, and at the same time improves the bending accuracy.

[0029] Example 2: Please see Figure 7 Furthermore, in conjunction with Embodiment 1, the stamping and bending mechanism 5 includes a support frame 51, which is fixedly installed on the top of the frame 1. A second hydraulic rod 52 is fixedly installed on the inner side of the top of the support frame 51. A bending die 53 is fixedly installed on the telescopic end of the second hydraulic rod 52. A guide column 54 is fixedly installed on the top of the bending die 53. A fixed cylinder 55 is fixedly installed on the inner side of the top of the support frame 51. A sliding cover 56 is fixedly installed on the top of the bending die 53. A fixed cover 57 is fixedly installed on the inner side of the top of the support frame 51, and the sliding cover 56 is slidably installed inside the fixed cover 57 to facilitate bending and forming of the steel plate.

[0030] Furthermore, there are two guide posts 54 and two fixed cylinders 55, and the two guide posts 54 and fixed cylinders 55 are symmetrically arranged with respect to the center line of the front of the support frame 51. The guide posts 54 are slidably installed inside the fixed cylinders 55, which facilitates the limiting sliding of the bending die 53.

[0031] In this embodiment, a second hydraulic rod 52 is fixed to the top of the support frame 51. A bending die 53 is fixedly installed at the telescopic end of the rod. A guide post 54 is provided on the top of the bending die 53, which slides in cooperation with the fixed cylinder 55 on the support frame 51 to ensure that the bending die 53 slides precisely in the vertical direction. At the same time, a sliding cover 56 is also provided on the top of the bending die 53, which is slidably installed inside the fixed cover 57 on the support frame 51, further enhancing the smoothness of movement and the guiding accuracy during the pressing process. During operation, the second hydraulic rod 52 drives the bending die 53 to move downward. The pressing surface of the bending die 53 cooperates with the V-groove of the sliding die 413 to bend the steel plate placed on the placement groove 416 into the required right-angle structure.

[0032] Example 3: Please see Figure 8Furthermore, in conjunction with Embodiments 1 and 2, the oil spraying lubrication mechanism 6 includes an oil spray pipe 61, which is fixedly installed inside the bending die 53. A nozzle 62 is fixedly installed at the outer end of the oil spray pipe 61. An oil pump 63 is fixedly installed inside the frame 1. A connecting hose 64 is fixedly installed between the oil pump 63 and the oil spray pipe 61. An oil storage tank 66 is fixedly installed inside the frame 1. An oil extraction pipe 65 is fixedly installed between the oil storage tank 66 and the oil pump 63. An oil filling port 67 is fixedly installed on the outside of the oil storage tank 66, which facilitates the even spraying of bending oil onto the bending die 53, thereby lubricating the bending die 53 and extending its service life.

[0033] Furthermore, the oil spray pipe 61 is provided with multiple branch pipes, which are symmetrically arranged around the center line of the right side of the bending die 53, and the nozzle 62 is fixedly installed on the branch pipes, so as to facilitate the synchronous spraying of bending oil on both sides of the bending die 53.

[0034] In this embodiment, an oil spray pipe 61 is fixedly installed inside the bending die 53. Multiple branches of the oil spray pipe 61 are equipped with nozzles 62, which are symmetrically distributed on both sides of the bending die 53. An oil storage tank 66 and an oil pump 63 are provided inside the frame 1. The oil pump 63 draws bending oil from the oil storage tank 66 through the oil extraction pipe 65, and then delivers the bending oil to the oil spray pipe 61 through the connecting hose 64. Finally, the oil is evenly sprayed onto the working surface of the bending die 53 by the nozzles 62, thereby achieving automatic and quantitative lubrication of the contact surface between the bending die 53 and the steel plate, reducing the frictional resistance during bending, reducing die wear, and extending the service life of the die.

[0035] In actual operation, when this device is used, the two first hydraulic rods 415 drive the two sliding molds 413 to slide symmetrically on the fixed rail 412, so that the sliding molds 413 are adjusted to the appropriate position according to the width of the steel plate. At the same time, the baffle 414 slides in the inner part of the housing 2. After the adjustment is completed, the steel plate is placed on the placement slots 416 of the two sliding molds 413. Then, the motor 422 drives the bidirectional screw 423 to rotate, so that the bidirectional screw 423 drives the two sliding seats 424 to slide inward synchronously. The sliding seats 424 drive the positioning push plate 425 to move inward. The positioning push plate 425 pushes the steel plate to the center from both sides. Then the motor 422 reverses, so that the sliding seats 424 drive the positioning push plate 425 to reset. The bending die 53 is driven to move downward by the second hydraulic rod 52, so that the bending die 53 cooperates with the sliding die 413 to bend the steel plate into a right-angle structure. After forming, the second hydraulic rod 52 drives the bending die 53 to move upward and reset. During the movement of the bending die 53, the guide column 54 slides in a limited position inside the fixed cylinder 55, and the sliding cover 56 slides in a limited position inside the fixed cover 57. After bending is completed, the two first hydraulic rods 415 drive the sliding die 413 to slide inward synchronously, so that the two sliding dies 413 push the bent iron accessory upward. After a period of use, bending oil is added to the inside of the oil storage tank 66 through the oil filling port 67. The bending oil is extracted through the oil extraction pipe 65 on the oil pump 63 and sent into the oil spray pipe 61 through the connecting hose 64. The bending oil is evenly sprayed onto the bending die 53 through the nozzle 62 on the oil spray pipe 61, so that the bending oil lubricates the bending die 53.
