Description

Technical Field

[0001] The present invention relates to the technical field of plate processing equipment, in particular to a taper straight welding machine. Background Art

[0002] For products that require sheet metal to be rolled into a cylindrical shape and then welded, such as kettle bodies, the existing processing method generally involves first using a mold to bend the sheet metal into a predetermined shape, and then welding the joints where welding is required. This method, due to the high shaping accuracy of the mold, creates a more standardized and accurate seam, resulting in a stable welding effect. However, the product needs to be demolded after welding, which reduces the efficiency of automated production.

[0003] The existing method forms a cylindrical structure by clamping the two sides of the plate and flipping them toward each other. However, the alignment effect of the welded joints formed in this way is relatively poor. More importantly, the existing method of clamping the plate generally clamps the plate by two movable clamping arms, which causes the height position of the plate after being clamped to have a certain degree of floating. As a result, when the two sides of the plate are clamped and then flipped for docking, it is easy to cause a height difference between the two welding edges to be welded, thereby affecting the welding quality. Summary of the Invention

[0004] The technical problem to be solved by the embodiments of the present invention is to provide a tapered straight welding machine with precise welding edge butt joint, good welding effect and high production efficiency.

[0005] In order to solve the above technical problems, an embodiment of the present invention provides a tapered straight welding machine, comprising a plate forming device for curling a plate into a cylindrical shape and a welding device, wherein the welding device is arranged above the plate forming device to weld the curled plate;

[0006] The sheet forming device includes a sheet material moving mechanism for moving the sheet material from the raw material station to the processing station and a curling mechanism provided above the sheet material moving mechanism. The processing station is provided with a positioning and lifting mechanism to lift the sheet material at the processing station to the clamping station of the curling mechanism.

[0007] The curling mechanism includes two rotating clamping mechanisms and a translation driving mechanism for controlling the opening and closing movement between the two rotating clamping mechanisms;

[0008] The rotary clamping mechanism includes a clamping mechanism and a flip driving mechanism for driving the clamping mechanism to flip, and the translation driving mechanism drives the clamping mechanism to move through the flip driving mechanism;

[0009] The clamping mechanism includes a clamping arm main body with a clamping opening, a clamping movable arm located in the clamping opening, and a top pressure driving component for driving the clamping movable arm to move up and down. The clamping movable arm is pressed toward the top surface of the clamping opening by the top pressure driving component to clamp and fix the plate.

[0010] As an improvement to the above solution, the top pressure drive assembly includes a lifting slider that drives the clamping movable arm and a synchronous driving slide bar that contacts the bottom of the lifting slider. The clamping arm body is provided with a lifting channel for guiding the lifting movement of the lifting slider and a translation channel for guiding the translation of the synchronous driving slide bar.

[0011] A guide slope is provided at the bottom of the lifting slider, and a notch is provided on the surface of the synchronous driving slide rod that is adapted to the guide slope, so that when the synchronous driving slide rod translates along the translation channel, the lifting slider disengages from the notch through the guide slope to lift the clamping movable arm.

[0012] As an improvement to the above solution, the clamping arm body includes an upper clamping arm and a lower clamping arm, and a preset distance is left between the upper clamping arm and the lower clamping arm to form the clamping opening;

[0013] The two side surfaces of the upper clamping arm and the lower clamping arm are respectively a clamping end surface and a welding end surface;

[0014] The welding end surface of the lower clamping arm is retracted inward by a preset distance relative to the welding end surface of the upper clamping arm, so that when the two clamping mechanisms are flipped toward each other and merged, the welding end surfaces of the lower clamping arms of the two clamping arm bodies are in contact with each other, and a welding gap facing the welding device is formed between the lower clamping arms of the two clamping arm bodies.

[0015] As an improvement of the above solution, the flip driving mechanism includes an opening and closing translation seat driven by the translation driving mechanism, a flip motor and a flip rocker arm connected to the clamping mechanism;

[0016] The flip motor is installed on the opening and closing translation seat to follow the translation movement of the opening and closing translation seat; the flip motor drives the clamping mechanism to flip by driving the flip rocker arm.

[0017] As an improvement to the above solution, the opening and closing translation seat is equipped with a rotation shaft angle adjustment base for mounting the flip motor, and the opening and closing translation seat is provided with a first rotation shaft for rotationally connecting the rotation shaft angle adjustment base and an arc-shaped travel hole for fixedly connecting the rotation shaft angle adjustment base and the opening and closing translation seat;

[0018] The flip rocker arm is hinged to the clamping mechanism via a rocker arm rotating shaft, and the flip rocker arm is provided with a clamping hole for clamping and fixing the rocker arm rotating shaft.

[0019] As an improvement of the above solution, the plate material moving mechanism includes a material moving base plate, a suction device for sucking the plate, a pusher for pushing the welded finished product out of the clamping station, and a material moving translation mechanism for driving the material moving base plate to move horizontally, and the pusher and the suction device are both provided on the material moving base plate;

[0020] The adsorption device moves back and forth between the raw material station and the processing station by following the material transfer substrate, so that when the adsorption device moves the plate to be processed from the raw material station to the processing station, the pusher pushes the finished product at the clamping station to the material receiving station, waiting for the plate at the processing station to move to the clamping station.

[0021] As an improvement to the above solution, the positioning and lifting mechanism includes a positioning and lifting base plate for supporting the plate and a positioning and lifting drive mechanism for driving the positioning and lifting base plate to and from the processing station and the clamping station;

[0022] The lifting base is provided with a plurality of adsorption holes communicated with the negative pressure pipe, so as to be used for adsorbing and fixing the plate on the surface of the positioning lifting base plate.

[0023] As an improvement to the above solution, the contour of the processing station is adapted to the plate;

[0024] The positioning and lifting mechanism further comprises a plurality of guide members for guiding the plate to fall into the processing station, and the guide members are distributed around the contour of the processing station;

[0025] One end side wall of the guide member is divided into a side positioning arc surface and a side guide arc surface located above the side positioning arc surface. When the plate falls to the processing station, the edge of the plate sequentially contacts the side guide arc surface and the side positioning arc surface.

[0026] The contact point between the side guide arc surface and the plate is located outside the contour of the processing station, and the contact point between the side positioning arc surface and the plate is located on the contour of the processing station.

[0027] As an improvement to the above solution, the invention further comprises a material receiving device, the material receiving device comprising a material receiving guide rod and a material receiving seat for mounting the material receiving guide rod, one end of the material receiving guide rod is connected to the material receiving seat, and the other end is located at the material receiving station;

[0028] After the welded cylindrical finished product is pushed to the material receiving station by the pushing rack, the material receiving guide rod can penetrate the cylindrical finished product so that the finished product can be stacked on the material receiving seat along the material receiving guide rod.

[0029] As an improvement to the above solution, the raw material station is provided with a loading device for stacking and storing the plate raw materials.

[0030] The loading device includes a loading lifting base plate for supporting the plate, a loading positioning rod for limiting the stacking position of the plate, and a loading lifting drive mechanism for driving the loading lifting base plate to move up and down, and the loading positioning rod is arranged around the outline of the raw material station;

[0031] Both sides of the raw material station are provided with blocking springs for separating the plates, so that when the plates are received by the plate moving mechanism, both sides of the plates overcome the obstruction of the blocking springs and arch up and deform.

[0032] The implementation of the present invention has the following beneficial effects:

[0033] The embodiment of the present invention discloses a tapered straight welding machine, comprising a plate forming device and a welding device, wherein the welding device is arranged above the plate forming device to weld the curled plate;

[0034] The sheet forming device includes a sheet material moving mechanism for moving the sheet material from the raw material station to the processing station and a curling mechanism provided above the sheet material moving mechanism. The processing station is provided with a positioning and lifting mechanism for lifting the sheet material at the processing station to the clamping station of the curling mechanism. Therefore, the setting of the positioning and lifting mechanism can provide a longitudinal operating space for the curling mechanism to perform the curling operation on the sheet material, thereby automatically completing the automatic loading of the sheet material to improve production efficiency.

[0035] Furthermore, the curling mechanism includes two rotating clamping mechanisms and a translation drive mechanism for controlling the opening and closing movement between the two rotating clamping mechanisms. Therefore, based on the compatibility of the above-mentioned operating space, for plates of different widths, the clamping distance between the two rotating clamping mechanisms can be controlled by the translation drive mechanism to adapt to the curling processing of plates of different widths;

[0036] The rotary clamping mechanism includes a clamping mechanism and a flip driving mechanism for driving the clamping mechanism to flip, and the translation driving mechanism drives the clamping mechanism to move through the flip driving mechanism;

[0037] The clamping mechanism includes a clamping arm main body with a clamping opening, a clamping movable arm located in the clamping opening, and a top pressure driving component for driving the clamping movable arm to move up and down. The clamping movable arm is pressed toward the top surface of the clamping opening by the top pressure driving component to clamp and fix the plate. Such an arrangement allows the plate to be clamped and fixed with the top surface of the clamping opening as a reference, and the height of the top surface is controllable and stable, so that after the plate is curled, the two welds of the plate can be accurately butted together to ensure the stability of the welding quality.

[0044] In order to make the objectives, technical solutions and advantages of the present invention more clear, the present invention will be described in further detail below with reference to the accompanying drawings.

[0045] See also Figure 1-4 An embodiment of the present invention provides a tapered straight welding machine, comprising a plate forming device for curling a plate into a cylindrical shape and a welding device 1, wherein the welding device 1 is arranged above the plate forming device to weld the curled plate; the welding device 1 is preferably a laser welder of the prior art, which generally includes a laser welding head and a laser translation mechanism for controlling the movement of the laser welding head.

[0046] The sheet forming device includes a sheet material transfer mechanism 2 for transferring the sheet material from the raw material station A to the processing station B and a curling mechanism 3 provided above the sheet material transfer mechanism 2. The processing station B is provided with a positioning and lifting mechanism 4 to lift the sheet material at the processing station B to the clamping station C of the curling mechanism 3, thereby allowing the curling mechanism 3 at a high position to have ample operating space.

[0047] The curling mechanism 3 includes two rotating clamping mechanisms 31 and a translation driving mechanism 32 for controlling the opening and closing movement between the two rotating clamping mechanisms 31. The translation driving mechanism 32 is preferably a screw transmission mechanism in the prior art, which generally includes a driving screw and a screw movable seat driven by the driving screw, and the rotating clamping mechanism 31 is installed on the screw movable seat.

[0048] The rotating clamping mechanism 31 includes a clamping mechanism and a flip driving mechanism 33 for driving the clamping mechanism to flip, and the translation driving mechanism 32 drives the clamping mechanism to move through the flip driving mechanism 33;

[0049] The clamping mechanism includes a clamping arm body 311 with a clamping opening 311a, a clamping movable arm 312 located in the clamping opening 311a, and a top-pressing driving component for driving the clamping movable arm 312 to move up and down. The clamping movable arm 312 is pressed toward the top surface of the clamping opening 311a by the top-pressing driving component to clamp and fix the plate.

[0050] Specifically, based on the relatively long side of the plate to be clamped, in order to ensure that the clamping movable arm 312 can rise stably and parallely, the top-pressing drive assembly includes a lifting slider 313 that drives the clamping movable arm 312 and a synchronous driving slide bar 314 that contacts the bottom of the lifting slider 313. The clamping arm body 311 is provided with a lifting channel 311b for guiding the lifting movement of the lifting slider 313 and a translation channel 311c for guiding the translation of the synchronous driving slide bar 314.

[0051] A guide slope 313a is provided at the bottom of the lifting slider 313, and a notch adapted to the guide slope 313a is provided on the surface of the synchronous driving slider 314, so that when the synchronous driving slider 314 translates along the translation channel 311c, the lifting slider 313 disengages from the notch through the guide slope 313a to lift the clamping movable arm 312.

[0052] Preferably, in order to improve the smoothness of the lifting slider 313 being separated from the notch, the bottom surface of the notch is a driving inclined surface 313b that fits with the guiding inclined surface 313a.

[0053] Accordingly, when the side length of the required clamping plate is too long, resulting in the length of the clamping movable arm 312 being too long, the lifting channel 311b and corresponding lifting slider 313 can be added to the clamping arm body 311 to evenly support the clamping movable arm 312, so that the clamping movable arm 312 can maintain a horizontal state and move up and down. Preferably, the clamping arm body 311 can also be provided with a lifting guide hole 311d, and the clamping movable arm 312 is equipped with a lifting guide column 3121 that is compatible with the lifting guide hole.

[0054] The clamping arm body 311 includes an upper clamping arm 3111, a lower clamping arm 3112 and a clamping arm seat 3113 for connecting the flipping drive mechanism 33, and a preset distance is left between the upper clamping arm 3111 and the lower clamping arm 3112 to form the clamping opening 311a; the clamping body is preferably an integrated structure, that is, the upper clamping arm 3111, the lower clamping arm 3112 and the clamping arm seat 3113 are an integrated U-shaped structural block.

[0055] The two side surfaces of the upper clamping arm 3111 and the lower clamping arm 3112 are respectively a clamping end surface 311e and a welding end surface 311f;

[0056] The welding end surface 311f of the lower clamping arm 3112 is retracted by a predetermined distance relative to the welding end surface 311f of the upper clamping arm 3111. This allows the welding end surfaces 311f of the lower clamping arms 3112 of the two clamping arm bodies 311 to abut against each other when the two clamping mechanisms are flipped toward each other and joined, thereby forming a welding gap between the lower clamping arms 3112 of the two clamping arm bodies 311, which faces the welding device 1. With this arrangement, as the sheet is pressed upward against the bottom surface of the upper clamping arm 3111, when the flipping drive mechanism 33 performs a curling operation, the upper clamping arm 3111 is flipped below the lower clamping arm 3112. This welding gap allows the two upper clamping arms 3111 to be positioned after the flipping operation is completed, relying on the abutment of the welding end surfaces 311f of the two upper clamping arms 3111. This ensures that the two welded edges of the sheet are precisely aligned after curling without affecting the welding operation.

[0057] The flipping drive mechanism 33 includes an opening and closing translation seat 331 driven by the translation drive mechanism 32, a flipping motor 332 and a flipping rocker arm 333 connected to the clamping mechanism; the flipping motor 332 is installed on the opening and closing translation seat 331 to follow the translation movement of the opening and closing translation seat 331; the flipping motor 332 drives the clamping mechanism to flip by driving the flipping rocker arm 333.

[0058] Furthermore, it can adapt to the curling requirements of different plates. For example, if the plate needs to be curled into a pot body shape with different tapers, the plate is fan-shaped, and accordingly, the angles between its two side edges are also different, so the corresponding flipping axial direction is also different.

[0059] Therefore, the opening and closing translation seat 331 is equipped with a rotating shaft angle adjustment base 334 for installing the flip motor 332. The opening and closing translation seat 331 is provided with a first rotating shaft 3341 for rotatingly connecting the rotating shaft angle adjustment base 334 and an arc-shaped stroke hole 335 for fixedly connecting the rotating shaft angle adjustment base 334 and the opening and closing translation seat 331, so as to make adjustments according to the angles of the two welding edges of the plate.

[0060] Accordingly, the tilting rocker arm 333 is hingedly connected to the clamping mechanism via a rocker arm shaft 336. The tilting rocker arm 333 is provided with a clamping hole 3331 for clamping and securing the rocker arm shaft 336. When adjustment is required, the clamping hole 3331 can be loosened to restore the rotatability of the rocker arm shaft 336. Once the setting angle of the tilting rocker arm 333 is determined, the clamping hole 3331 can be tightened to secure the rocker arm shaft 336. The clamping hole 3331 is composed of two clamping blocks, each having corresponding concave clamping surfaces that are connected by mating bolts to achieve the tightening and loosening of the clamping hole 3331.

[0061] See also Figure 6 In order to improve production efficiency, the plate material moving mechanism 2 includes a material moving base plate 21, an adsorption device for adsorbing the plate, a pushing rack 22 for pushing the welded finished product out of the clamping station C, and a material moving translation mechanism 23 for driving the material moving base plate 21 to move horizontally. The pushing rack 22 and the adsorption device are both arranged on the material moving base plate 21; the material moving translation mechanism is preferably a screw transmission mechanism in the existing technology.

[0062] The adsorption device moves back and forth between the raw material station A and the processing station B by following the material transfer base plate 21. As the adsorption device moves the sheet material to be processed from the raw material station A to the processing station B, the pusher 22 pushes the finished product at the clamping station C to the material receiving station, waiting for the sheet material at the processing station B to be moved to the clamping station C. The adsorption device includes an adsorption base plate 24, a suction cup 25 provided on the adsorption base plate 24, and an adsorption lifting drive mechanism 26 for driving the adsorption base plate 24 to rise and fall. The adsorption lifting drive mechanism 26 is preferably a pneumatic telescopic rod mechanism of the prior art.

[0063] This arrangement allows the loading and unloading processes of the plate to be combined and completed together, thereby greatly improving production efficiency. Accordingly, the taper direct welding machine further includes a material receiving device 5, which includes a material receiving guide rod 51 and a material receiving seat 52 for mounting the material receiving guide rod 51. One end of the material receiving guide rod 51 is connected to the material receiving seat 52, and the other end is located at the material receiving station D.

[0064] After the welded cylindrical finished product is pushed to the material receiving station by the pushing rack 22 , the material receiving guide rod 51 can penetrate the cylindrical finished product so that the finished product can be stacked on the material receiving seat 52 along the material receiving guide rod 51 .

[0065] See also Figure 5 The positioning and lifting mechanism 4 includes a positioning and lifting base plate 41 for supporting the plate and a positioning and lifting drive mechanism 42 for driving the positioning and lifting base plate 41 to move back and forth between the processing station B and the clamping station C; the positioning and lifting drive mechanism 42 can be a pneumatic telescopic rod mechanism, a screw transmission mechanism, etc. in the existing technology.

[0066] The lifting base is provided with a plurality of adsorption holes connected to the negative pressure pipe, so as to adsorb and fix the plate on the surface of the positioning lifting base plate 41 to prevent the plate from deflecting during the lifting movement.

[0067] In detail, the contour of the processing station B is adapted to the plate, and the positioning and lifting mechanism 4 further includes a plurality of guide members 6 for guiding the plate to fall into the processing station B, and the guide members 6 are distributed around the contour of the processing station B;

[0068] One sidewall of the guide member 6 is divided into a side positioning curved surface 61 and a side guide curved surface 62 located above the side positioning curved surface 61. As the plate falls toward processing station B, its edge sequentially contacts the side guide curved surface 62 and the side positioning curved surface 61. The contact points between the side guide curved surface 62 and the plate lie outside the contour of processing station B, while the contact points between the side positioning curved surface 61 and the plate lie within the contour of processing station B. This means that the positioning and guidance of the side positioning curved surfaces 61 and 62, combined with the suction and fixation provided by the suction holes, significantly reduces plate deviation after delivery to the clamping station C, thereby ensuring optimal welding results.

[0069] The raw material station A is provided with a loading device 7 for stacking and storing plate raw materials. The loading device 7 includes a loading lifting base plate 71 for supporting the plates, a loading positioning rod 72 for limiting the stacking position of the plates, and a loading lifting drive mechanism 73 for driving the loading lifting base plate 71 to move up and down. The loading positioning rod 72 is arranged around the outline of the raw material station A; the loading lifting drive mechanism 73 is preferably a screw transmission mechanism in the prior art.

[0070] To address the problem of stacked sheets adhering to each other, preventing the suction device from ensuring that only a single sheet is removed, sheet-separating springs 74 are provided on both sides of the raw material station A. When the sheet is received by the sheet transfer mechanism 2, the two sides of the sheet overcome the obstruction of the springs 74 and arch upward. Thus, the arching of the sheet allows for separation.

[0071] The above is 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 principles of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
