Description

Technical Field

[0001] The invention relates to the technical field of keel processing, and in particular to a keel production line capable of continuous processing. Background Art

[0002] Lightweight steel keels are currently the main decorative materials with huge demand. In the current production process, keels are generally produced by a single operator. The specific steps are as follows: the operator inserts the steel strip from the opener into the keel machine. When the keel machine completes the processing of the roll of steel strip, the operator inserts the next roll of steel strip into the keel machine again, and repeats the above steps.

[0003] The existing keel processing equipment has the following defects:

[0004] 1) Since the steel belt has a large bending stress, the operator needs to exert a large force to overcome the bending stress of the steel belt when inserting the steel belt into the keel machine, resulting in high labor intensity. The operator is also easily scratched by the steel belt, which poses a safety hazard.

[0005] 2) Since the production specifications of the keel are difficult to match with the actual length of the steel strip, during the actual processing, the length of the last section of the steel strip may be less than the processing specifications of the keel, and the last section of the steel strip will be wasted, increasing the production cost.

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] like Figure 1 As shown, the present invention provides a specific implementation of a continuously processable keel production line, comprising an uncoiler 1, a keel machine 2 and a welding device 3.

[0039] The uncoiler 1 is an existing conventional device, which supports the steel coil by tightening the inner hole of the steel coil and can rotate itself.

[0040] The keel machine 2 is an existing conventional equipment, which is used to process the steel strip into a keel; it can generate traction force by itself, and cooperate with the unwinding machine 1 to realize the transportation of the steel strip.

[0041] The welding device 3 is arranged between the uncoiler 1 and the keel machine 2, and is used to weld the head of the steel strip at the uncoiler 1 and the tail of the steel strip at the keel machine 2, so that the steel strip at the uncoiler 1 and the steel strip at the keel machine 2 can form an integral steel strip.

[0042] Before welding, the head of the steel strip at the uncoiler 1 and the tail of the steel strip at the keel machine 2 need to be cut so that the ends of the two steel strips can be aligned, the two steel strips are parallel to each other in the width direction, and the two steel strips are located on the same straight line in the length direction.

[0043] As the steel strip is conveyed, the radius of the steel strip at the uncoiler 1 will change, causing the inclination angle of the steel strip between the uncoiler 1 and the keel machine 2 relative to the horizontal plane to change; therefore, in this embodiment, the welding device 3 can be moved to avoid the welding device 3 from obstructing the conveyance of the entire steel strip formed after welding.

[0044] This embodiment provides an example of a welding device 3, such as Figure 7 As shown:

[0045] The welding device 3 includes a clamping assembly 31 and a welding assembly 32 which are arranged on a welding platform 35 .

[0046] Among them, two groups of clamping components 31 are symmetrically arranged along the conveying direction of the steel strip, which are used to position and clamp the head of the steel strip at the uncoiler 1 and the tail of the steel strip at the keel machine 2, respectively, and align the ends of the two steel strips with a reserved gap.

[0047] The welding assembly 32 is disposed between the two sets of clamping assemblies 31 and can move along the gap to perform welding at the gap; the welding assembly 32 includes a welding head 321 and a driving mechanism 322 for driving the welding head 321 to move.

[0048] The welding head 321 is a conventional welding head 321 in the prior art. The driving mechanism 322 adopts a screw pair structure. The welding head 321 is vertically downwardly arranged at the nut of the screw pair. The movement of the welding head 321 driven by the screw pair can improve the movement accuracy and thus enhance the welding quality.

[0049] A third bracket 323 is vertically disposed on the welding platform 35, and a driving mechanism 322 is horizontally disposed on the third bracket 323.

[0050] The structure of the third bracket 323 is set as follows: when the welding device 3 is moved, there is no contact between the third bracket 323 and the integral steel strip formed after welding; in this embodiment, the third bracket 323 is preferably a ┌-shaped bracket, and the welding device 3 moves in the direction of one side of the vertically arranged support column.

[0051] The welding device 3 also includes a grinding component 33, which is used to grind the weld formed between the two steel strips to improve the surface quality of the keel after forming.

[0052] This embodiment also provides an embodiment of the clamping assembly 31, such as Figure 3-Figure 5 As shown:

[0053] The clamping assembly 31 includes an upper clamping plate 311 , a lower clamping plate 312 and a first telescopic mechanism 313 .

[0054] Among them, the lower clamping plate 312 is arranged on the welding platform 35, and the upper surface of the lower clamping plate 312 is vertically upwardly provided with a first bracket 314, the movable end of the first telescopic mechanism 313 is vertically downwardly arranged on the first bracket 314, and the upper clamping plate 311 is arranged at the movable end of the first telescopic mechanism 313, and the upper clamping plate 311 is arranged parallel to the lower clamping plate 312, so that the upper clamping plate 311 and the lower clamping plate 312 can clamp the steel belt.

[0055] The structure of the first bracket 314 is set as follows: when the welding device 3 is moved, there is no contact between the first bracket 314 and the integral steel strip formed after welding; in this embodiment, the first bracket 314 is preferably a ┌-shaped bracket, and the welding device 3 moves toward one side of the vertically arranged support column.

[0056] A first groove 3121 is provided on the upper surface of the lower clamping plate 312, and the width of the first groove 3121 is consistent with the width of the steel strip. A protrusion 3111 that can match with the first groove 3121 is provided on the lower surface of the upper clamping plate 311; the edges of the grooves on the lower clamping plates 312 of the two clamping assemblies 31 are arranged on the same straight line along the transmission direction of the steel strip, so that the edges of the steel strips clamped by the two sets of clamping assemblies 31 are on the same straight line along the transmission direction of the steel strip.

[0057] The function of the first groove 3121 is to facilitate the operator to perform preliminary positioning when placing the end of the steel belt on the lower clamping plate 312 .

[0058] Furthermore, at least one set of lead screw pairs 315 is respectively provided on the welding platform 35 corresponding to the two sets of clamping assemblies 31. Preferably, the two sets of clamping assemblies 31 are respectively provided with two sets of lead screw pairs 315, and the lead screw pairs 315 are arranged along the conveying direction of the steel strip.

[0059] The lower surface of the lower clamping plate 312 is connected to the nut of the screw pair 315, so that the two sets of clamping assemblies 31 can open and close along the conveying direction of the steel strip to adjust the gap between the ends of the steel strip clamped by the two sets of clamping assemblies 31 so that the gap meets the welding requirements.

[0060] During the welding process, in order to improve the welding quality, it is necessary to provide limited support to the welding point from below. Therefore, this embodiment provides the following embodiments:

[0061] The lower clamping plates 312 of the two sets of clamping assemblies 31 are provided with buffer blocks 316 on the facing edges. The buffer blocks 316 and the lower clamping plates 312 are connected by spring telescopic rods 317. The spring telescopic rods 317 are arranged along the conveying direction of the steel strip. The bottom of the buffer blocks 316 is provided with rollers 3162 that are in rolling contact with the welding platform 35 to facilitate the movement of the buffer blocks 316.

[0062] The upper surface of the buffer block 316 is provided with a second groove 3161 penetrating the buffer block 316 in the horizontal direction. The second groove 3161 can form an integrated groove with the first groove 3121 for initial positioning of the steel strip.

[0063] The edge of the buffer block 316 away from the lower clamping plate 312 along the transmission direction of the steel strip is used to position the end of the steel strip to ensure that the end of the cut steel strip is flush with the edge of the buffer block 316 when placed on the lower clamping plate 312.

[0064] The welding platform 35 is provided with a limit block 318 between the two lower clamping plates 312. The telescopic length of the spring telescopic rod 317 and the length of the limit block 318 in the direction of steel strip transmission can ensure that after the blanking plate is blocked by the limit block 318, the interval between the ends of the steel strip clamped by the two clamping assemblies 31 meets the welding requirements.

[0065] Moreover, the upper surfaces of the grooves at the limit block 318, the buffer block 316 and the groove at the lower clamping plate 312 are on the same horizontal plane, so that the limit block 318 will not restrict the movement of the end of the steel strip along the transmission direction of the steel strip, and can also support the ends of the two steel strips; thereby achieving effective support of the steel strip at the bottom of the steel strip during the welding process.

[0066] In order to effectively cut the end of the steel strip, the present embodiment provides the following embodiments: Figure 6 As shown:

[0067] The welding device 3 also includes a cutting assembly 34, which includes a second telescopic mechanism 341 and a cutting blade 342. The cutting blade 342 is arranged at the movable end of the second telescopic mechanism 341. A second bracket 343 is provided on the welding platform 35, and the movable end of the second telescopic mechanism 341 is vertically downwardly arranged on the second bracket 343.

[0068] The structure of the second bracket 343 is set as follows: when the welding device 3 is moved, there is no contact between the second bracket 343 and the integral steel strip formed after welding; in this embodiment, the second bracket 343 is preferably a ┌-shaped bracket, and the welding device 3 moves in the direction of one side of the vertically arranged support column.

[0069] The cutting blade 342 and the edge of the buffer block 316 are on the same vertical plane, so that the cutting blade 342 can cut the end of the steel strip along the edge of the buffer block 316 so that the welding point of the steel strip is flush with the edge of the buffer block 316.

[0070] The cutting blade 342 applies a squeezing force to the buffer block 316 during the cutting process. In order to prevent the buffer block 316 from moving during the cutting process of the steel strip end, the present embodiment provides the following embodiments:

[0071] An electric telescopic rod 319 is provided on the edge of the lower clamping plate 312 to act on the edge of the buffer block 316; the electric telescopic rod 319 can extend when the cutting blade 342 cuts the steel strip, and impose restrictions on the buffer block 316 along the conveying direction of the steel strip to avoid the buffer block 316 from being displaced along the telescopic direction of the spring telescopic rod 317; the electric telescopic rod 319 can retract after the cutting blade 342 cuts the steel strip to release the restrictions imposed on the buffer block 316.

[0072] This embodiment also provides an embodiment of the grinding assembly 33, such as Figure 7 As shown:

[0073] The grinding assembly 33 includes a third telescopic mechanism 331 , a rotating motor 332 and a grinding disc 333 ; the rotating motor 332 is arranged at the movable end of the third telescopic mechanism 331 , and the rotating shaft of the rotating motor 332 is vertically downward; the grinding disc 333 is arranged at the end of the rotating shaft.

[0074] The movable end of the third telescopic mechanism 331 is vertically downwardly arranged on the driving part of the driving mechanism 322 that drives the welding assembly 32 to move; in this embodiment, the driving mechanism 322 is a screw pair 315 mechanism, and the nut of the screw pair 315 mechanism is vertically provided with a mounting plate, and the third telescopic mechanism 331 and the welding head 321 are both arranged on the mounting plate; the movable end of the third telescopic mechanism 331 is vertically downwardly arranged, so that the third telescopic mechanism 331 can move synchronously with the welding head 321.

[0075] After the welding head 321 welds the steel strip, the third telescopic mechanism 331 drives the grinding disc 333 to move downward to grind the weld so that the surface of the weld tends to be smooth.

[0076] In order to realize the movement of the welding device 3, the present embodiment also provides the following embodiments. Figure 1 and Figure 2 As shown:

[0077] A track 4 is laid between the uncoiler 1 and the keel machine 2 in a direction perpendicular to the steel strip transmission direction. The welding device 3 also includes a moving mechanism 5 that carries the welding platform 35 , and the moving mechanism 5 can move along the track 4 .

[0078] The moving mechanism 5 is a common electric trolley in the prior art. After the welding device 3 completes welding, the first telescopic mechanism 313 drives the upper clamping plate 311 to move upward, and the electric trolley moves toward the side of the vertically arranged support column of the ┌-shaped bracket, so that the steel belt is separated from the welding device 3; during the moving process, the operator can manually control the position of the steel belt between the upper clamping plate 311 and the lower clamping plate 312 to avoid scratching each other.
