Description

Technical Field

[0001] The invention relates to the technical field of material processing, and in particular to a special robot for bending a transformer front cabin shell. Background Art

[0002] The transformer front cabin shell is mainly used to protect the internal structure of the transformer. It is mainly made by bending the steel plate into a rectangular or right-angle C-shaped structure and then welding it to complete the structure.

[0003] In the existing operation process, since the bending process of the steel plate is relatively fast and mostly at right angles, stress concentration is obvious at the bending point. The paint wrapped on the surface is also easily detached due to the shrinkage of the material. Long-term exposure is very likely to cause cracks. At the same time, the release of stress also affects the shape retention. The existing method usually uses vibration to remove stress, which leads to prolonged manufacturing time and low efficiency.

The specific implementation method thereof is as follows:

[0019] The operator first passes the steel plate between two sets of transport rollers, and then the transport rollers drive the steel plate to be transferred between two sets of fixed rollers. After a certain distance of transfer, the flip motor is started to rotate the flip rotating rod, and the flip rotating rod drives the flip plate to flip, and the steel plate portion exceeding the fixed roller is vertically bent, and the bending angle is a positive arc angle. At this time, the stress of the steel plate is slightly lower than the right angle. Then the thrust cylinder is started. While the thrust cylinder drives the clamping plate to move upward, the meshing rack continues to mesh upward with the meshing gear on the extended rotating rod. Then, when the clamping plate moves upward along the guide of the sliding long rod sliding in the sliding through hole, the meshing rack meshes with the meshing gear. The gear flips the fixed cross plate to clamp the steel plate between the clamping plate and the fixed cross plate. At this time, the thrust cylinder is continued to be lifted to drive the lifting cross bar on the fixed cross plate to resist the support spring and slide upward on the lifting rod. At the same time, the variable diameter cam is rotated by the cylinder or other equipment. The attached figure is not drawn to achieve the effect. The variable diameter cam is used to push the fixed plate to squeeze the thrust spring toward the support column, and the fixed point of the steel plate and the fixed roller is changed. In the process of the steel plate being pulled by the clamping plate and the fixed cross plate, the bending angle is changed from a positive circular arc angle to an arc angle with a changing slope, which further reduces the stress and completes the bending of the steel plate, effectively solving the stress problem after bending.

[0020] Due to the different thicknesses of some steel plates, when the steel plates pass between the transport rollers, the transport rollers squeeze the extrusion springs, change their positions in the movable slots, and after being recorded by the distance sensor, change the dwell time of the flipping plate, so that the fixed time of the steel plate bending increases with the increase in thickness, thereby better maintaining the structure of the steel plate after bending.

[0021] At the same time, due to the change in steel plate thickness, the fixed gap of the fixed roller needs to be changed. The rotating connecting block adjusts the spacing between the rotating axes on the two sets of fixed rollers. At the same time, the adjusting screw is rotated to change the spacing between the fixed cross plate and the lifting cross bar clamp to match the thickness of different steel plates.

[0022] The equipment has a simple structure and utilizes the movement of fixed points to effectively achieve the variable curvature bending problem at the bending point of the steel plate, effectively solving the cracking at the bending point caused by stress concentration, maintaining good bending, and has good practicality, which is beneficial to the promotion and use of the equipment.

[0039] Reference Figure 1 , 2 As shown, it is beneficial that a plurality of transport racks 1 are provided at one end of the two sets of sliding adjustment rods 222 away from the thrust spring 223.

[0042] In practice, when the variable diameter cam 5 rotates, the outer edge of the variable diameter cam 5 that fits the fixed plate 22 gradually moves away from the fixed point of rotation, directly squeezing the fixed plate 22 close to the supporting column 21, effectively changing the distance between them. At the same time, the rotation of the variable diameter cam 5 is assisted by an external force, which is not drawn in the accompanying drawings.

[0043] Advantageously, the lifting assembly includes a supporting bottom rod 411, which is arranged on a side of the fixing mechanism 2 away from the lifting cross bar 41, and lifting rods 412 are provided at both ends of the supporting bottom rod 411.

[0045] Working principle of the present invention:

[0046] The operator first passes the steel plate 101 between the two groups of transport rollers 13, and then the transport rollers 13 drive the steel plate 101 to be transported between the two groups of fixed rollers 23. After continuing to transport the steel plate 101 for a certain distance, the operator starts the flip motor 34 to rotate the flip rotating rod 33. The flip rotating rod 33 drives the flip plate 31 to flip, and the portion of the steel plate 101 that exceeds the fixed rollers 23 is vertically bent, and the bending angle is a positive arc angle. At this time, the stress of the steel plate 101 is slightly lower than that of the right angle. Then, the thrust cylinder 37 is started. While the thrust cylinder 37 drives the clamping plate 36 to move upward, the meshing rack 362 continues to mesh upward with the meshing gear 422 on the extended rotating rod 421. Then, when the clamping plate 36 moves upward along the guide of the sliding long rod 361 sliding in the sliding through hole 311, the meshing rack 362 meshes with the meshing gear 422. The meshing gear 422 flips the fixed cross plate 42 to clamp the steel plate 101 between the clamping plate 36 and the fixed cross plate 42. At this time, the thrust cylinder 37 is continuously lifted to drive the lifting cross bar 41 on the fixed cross plate 42 to resist the support spring 413 and slide upward on the lifting rod 412. At the same time, the variable diameter cam 5 is rotated by the cylinder or other equipment. The attached drawings are not drawn. The effect can be achieved. The variable diameter cam 5 is used to push the fixed plate 22 to squeeze the thrust spring 223 toward the support column 21, and the fixing point of the steel plate 101 and the fixed roller 23 is changed. In the process of the steel plate 101 being subjected to the tension of the clamping plate 36 and the fixed cross plate 42, the bending angle is changed from a positive circular arc angle to an arc angle with a changing slope, thereby further reducing the stress, completing the bending of the steel plate 101, and effectively solving the stress problem after bending.

[0047] Due to the different thicknesses of some steel plates 101, when the steel plates 101 pass between the transport rollers 13, the transport rollers 13 squeeze the extrusion springs 14, changing the position in the movable groove 112. After being recorded by the distance sensor 15, the dwell time of the flipping plate 31 is changed, so that the fixed time of the bending of the steel plate 101 increases with the increase of thickness, thereby better maintaining the structure of the steel plate 101 after bending.

[0048] At the same time, due to the change in the thickness of the steel plate 101, it is necessary to change the fixed gap of the fixed roller 23. The rotating connecting block 24 adjusts the spacing between the rotating axes on the two sets of fixed rollers 23. At the same time, the adjusting screw 431 is rotated to change the spacing between the fixed cross plate 42 and the lifting cross bar 41 to match the thickness of different steel plates 101.

[0049] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", etc. should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
