Referring to fig. 1, an automatic coil stock welding machine comprises a frame 1, a coil stock mechanism and a welding mechanism 2, wherein the coil stock mechanism comprises paired lifting support brackets 3 arranged on the frame, mutually independent paired primary bending clamp arms 4 arranged at two ends of a horizontal symmetrical center line of the lifting support brackets 3, paired leveling top plates 5 and flattening mechanisms 6 arranged above the lifting support brackets 3, paired secondary bending clamp blocks 7 arranged between the leveling top plates 5 and the lifting support brackets 3 and in the same direction as the layout direction of the lifting support brackets 3, the whole primary bending clamp arms 4 are in the same direction as the movement direction of the lifting support brackets 3, the secondary bending clamp blocks 7 are connected with the output end of a rotary servo motor 70 horizontally arranged above the frame, and clamping cushion blocks 8 which are relatively static with the frame 1 are arranged between the secondary bending clamp blocks 7, the welding mechanism 2 is connected with a movable welding platform 9 which moves along the length direction of the clamping cushion block 8, and the output end of the welding mechanism 2 is right above the clamping cushion block 8.
The processing flow of the invention is as follows: when the conventional coil stock welding is carried out, the driving devices of the primary bending clamping arms 4 positioned at the two sides of the lifting support bracket 3 have consistent motion parameters due to the standard cylindrical structure; referring to fig. 8, firstly, a sheet is placed at the upper end of the lifting support bracket 3, then the primary bending clamp arms are lifted to the horizontal plane of the sheet synchronously, then the sheet is clamped at two sides, and the sheet is stretched downwards until the two ends of the sheet are raised upwards and the part clamped by the primary bending clamp arms 4 is in a circular arc shape, wherein, in order to ensure that the circular arc is bent uniformly, the primary bending clamp arms 4 at two sides are seen from the horizontal plane at the side of the sheet, one is inclined to the left and the other is inclined to the right, so that the problem of arc deformation of the pulled sheet can be avoided; then the lifting support bracket 3 and the primary bending clamp arm 4 keep the current relative positions to rise simultaneously, at the moment, the leveling top plate 5 draws close inwards from two sides, so that two ends of the sheet can be supported by the lower surface of the leveling top plate 5 after penetrating through the secondary bending clamp block 7, and the edges of the two ends of the sheet are determined to be positioned on the same horizontal plane, thus ensuring that the rolled pipe is uniform up and down when subsequent bending operation is carried out; referring to fig. 9, after the two ends of the sheet are leveled, the secondary bending clamp 7 fixes (does not necessarily clamp) the two ends of the leveled sheet, and under the action of the rotary servo motor 70, the sheet is bent inward until the positions for welding at the two ends are mutually folded or even overlapped at the upper end of the clamping cushion block 8; then the flattening mechanism 6 presses down to enable both ends of the sheet to be in a state of being capable of being welded at any time; the flattening mechanism 6 is kept in a flattened state, and then the welding mechanism 2 performs laser welding along the position of a welding line under the action of the movable welding platform 9 until the two end parts of the sheet are welded to be dead, so that the welding forming of the coiled material is completed.
Compared with the traditional die-sinking coil welding equipment, the equipment is different in that as long as the sheet is not too long or too short, in the process that the two sides of the sheet are clamped by the primary bending clamping arm 4 to be pulled down, only the two ends of the sheet are required to enter the clamping range of the secondary bending clamping block 7, when the sheet is short, the pulling-down distance of the primary bending clamping arm 4 is relatively shortened, and when the sheet is long, the pulling-down distance of the primary bending clamping arm 4 is long, so that the requirements of coil processing technologies with different diameters can be met.
When the tapered sheet material is rolled, the difference between the conventional rolling operation and the conventional rolling operation is that the tapered sheet material is in a fan shape instead of a rectangular shape, so that the finished product from rolling is in a shape with a narrow top and a wide bottom or in a shape with a wide top and a narrow bottom, and in order to ensure that the edges of the two end parts of the sheet material can be aligned in the process of bending the secondary bending clamping block 7, the primary bending clamping arm 4 has different action flows; first, as shown in fig. 8, the initial clamping operation is the same as the normal material rolling operation, and the sheet material is lifted to the same horizontal level of the lifting support bracket 3 to clamp both sides of the fan-shaped sheet material; referring to fig. 9, the primary bending clamp arm 4 is pulled downward until both ends of the sheet are tilted upward, and then the lifting support bracket 3 and the primary bending clamp arm 4 are lifted synchronously; the leveling top plate 5 and the secondary bending clamp block 7 are arranged in the same manner, and after the two ends of the sheet pass through the clamping range of the secondary bending clamp block 7, the difference is that compared with the conventional stretch bending operation shown in fig. 8, because the heights of the two sides of the sheet are different, the primary bending clamp arm 4 on the higher side needs to be lifted by a smaller amount or the shorter side needs to be lifted by a larger amount, so that the edges of the two ends of the sheet are at the same horizontal height and are completely supported by the lower end face of the leveling top plate 5, and meanwhile, when the secondary bending clamp block 7 can fix the two ends of the sheet, the same uniform part can be extended out for subsequent rolling, flattening and welding operations; finally, after the welding mechanism 2 completes the welding operation, the tapered rolling process is completed.
According to the invention, by changing the ascending amount of the primary bent clamping arms 4 at two sides, the processing of a standard cylindrical barrel can be converted into the processing of a tapered winding drum only by changing parameter setting on the premise of not changing the installation and connection mode and not opening the die, and the processing requirements can be met by the adaptive taper range and processing precision, so that the efficiency is high, the cost is low, and the processing effect is good.
