Description

Technical Field

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

[0002] For products that need to be rolled into a cylindrical shape and welded, such as the body of a kettle, the existing processing method generally includes: firstly, the sheet is rolled into a preset shape through a shaping mold, and then the joints that need to be welded are welded. In this way, based on the high shaping accuracy of the mold, the joint seams formed by the curling are more standard and accurate, so that the welding effect is stable. However, correspondingly, the product needs to be demoulded after welding, and the automated production efficiency is low.

[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 by this method 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.

[0010] As an improvement of the above solution, the top pressure driving 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, and a lifting channel for guiding the lifting and lowering activity of the lifting slider and a translation channel for guiding the translation of the synchronous driving slide bar are provided in the clamping arm body;

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

[0012] As an improvement of the above solution, the clamp arm body includes an upper clamp arm and a lower clamp arm, and a preset distance is left between the upper clamp arm and the lower clamp 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 clamp arm is retracted inward by a preset distance relative to the welding end surface of the upper clamp arm, so that when the two clamping mechanisms are flipped toward each other and combined, the welding end surfaces of the lower clamp arms of the two clamp arm bodies fit together, and a welding gap facing the welding device is formed between the lower clamp arms of the two clamp 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;

[0020] The adsorption device moves back and forth between the raw material station and the processing station by following the movement of 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 rack 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 of the above solution, the positioning and lifting mechanism includes a positioning and lifting base plate for supporting the plate and a positioning and lifting driving 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 which are connected with the negative pressure pipeline, so as to adsorb and fix the plate on the surface of the positioning lifting base plate.

[0023] As an improvement of 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] The side wall at one end 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.

[0028] After the welded cylindrical finished product is pushed to the material receiving station by the material 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 of 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 comprises 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 driving mechanism for driving the loading lifting base plate to move up and down, and the loading positioning rod is arranged around the contour of the raw material station;

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

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

[0035] Moreover, 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. 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 driving mechanism to adapt to the curling processing of plates of different widths;

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

[0044] In order to make the objectives, technical solutions and advantages of the present invention more clear, the present invention will be further described in 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 sheet forming device for curling a sheet into a cylindrical shape and a welding device 1, wherein the welding device 1 is arranged above the sheet forming device to weld the curled sheet; 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 moving mechanism 2 for moving the sheet material from the raw material station A to the processing station B and a curling mechanism 3 arranged above the sheet material moving 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, so that the curling mechanism 3 at a high position can 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 flipping driving mechanism 33 for driving the clamping mechanism to flip, and the translation driving mechanism 32 drives the clamping mechanism to move through the flipping 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 pressure 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 pressure 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 improve the ability of the clamping movable arm 312 to rise stably and parallelly, the top pressure driving assembly includes a lifting slider 313 driving the clamping movable arm 312 and a synchronous driving slide bar 314 in contact with the bottom of the lifting slider 313, and a lifting channel 311b for guiding the lifting and lowering activity of the lifting slider 313 and a translation channel 311c for guiding the translation of the synchronous driving slide bar 314 are provided in the clamping arm body 311;

[0051] A guiding slope 313a is provided at the bottom of the lifting slider 313, and a notch matched with the guiding 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 can disengage from the notch through the guiding 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 the guiding inclined surface 313a.

[0053] Accordingly, when the side length of the required clamping plate is too long and the length of the clamping movable arm 312 is correspondingly too long, the lifting channel 311b and the 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 adapted to 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 clamp arm 3112 is retracted by a preset distance relative to the welding end surface 311f of the upper clamp arm 3111, so that when the two clamping mechanisms are flipped toward each other and combined, the welding end surfaces 311f of the lower clamp arms 3112 of the two clamp arm bodies 311 are in contact with each other, and a welding gap is formed between the lower clamp arms 3112 of the two clamp arm bodies 311 toward the welding device 1. In this configuration, based on the sheet being pressed upward against the bottom surface of the upper clamp arm 3111, when the flip driving mechanism 33 performs a curling operation, the upper clamp arm 3111 will be flipped to the bottom of the lower clamp arm 3112, so that the welding gap can be used to position the flipping action by relying on the mutual contact of the welding end surfaces 311f of the two upper clamp arms 3111 after the flipping action is completed, so that the welding operation is not affected, and the two welding edges of the sheet can be accurately aligned after curling.

[0057] The flipping driving mechanism 33 includes an opening and closing translation seat 331 driven by the translation driving 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 rotationally connecting the rotating shaft angle adjustment base 334 and an arc-shaped travel 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] Correspondingly, the flip rocker arm 333 is hinged with the clamping mechanism through the rocker arm shaft 336. The flip rocker arm 333 is provided with a clamping hole 3331 for clamping and fixing 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. After the setting angle of the flip rocker arm 333 is determined, the clamping hole 3331 can be tightened to fix the rocker arm shaft 336. The clamping hole 3331 is composed of two clamping blocks, and the clamping blocks are provided with clamping concave surfaces corresponding to each other, which are connected by matching bolts to achieve the looseness and tightness 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 pusher 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 translate. The pusher 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 prior art.

[0062] The adsorption device moves back and forth between the raw material station A and the processing station B by following the material transfer substrate 21, so that when the adsorption device moves the plate 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, so that the plate at the processing station B is moved to the clamping station C. The adsorption device includes an adsorption substrate 24, a suction cup 25 provided on the adsorption substrate 24, and an adsorption lifting drive mechanism 26 for driving the adsorption substrate 24 to lift and lower. The adsorption lifting drive mechanism 26 is preferably a pneumatic telescopic rod mechanism in the prior art.

[0063] With such an arrangement, the loading and unloading processes of the plate can be combined and completed together, thereby greatly improving production efficiency. Accordingly, the taper straight welding machine also includes a material receiving device 5, the material receiving device 5 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 driving 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 driving mechanism 42 can be a pneumatic telescopic rod mechanism, a screw transmission mechanism, etc. in the prior art.

[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] The side wall at one end of the guide member 6 is divided into a side positioning arc surface 61 and a side guide arc surface 62 located above the side positioning arc surface 61. When the plate falls to the processing station B, the edge of the plate contacts the side guide arc surface 62 and the side positioning arc surface 61 in turn; the contact point between the side guide arc surface 62 and the plate is located outside the contour of the processing station B, and the contact point between the side positioning arc surface 61 and the plate is located on the contour of the processing station B. That is, under the positioning and guidance of the side positioning arc surface 61 and the side guide arc surface 62, and in combination with the adsorption and fixation of the adsorption holes, the deviation of the plate after being sent to the clamping station C can be greatly reduced, thereby ensuring the welding effect.

[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 lift and move, the loading positioning rod 72 is arranged around the contour of the raw material station A; the loading lifting drive mechanism 73 is preferably a screw transmission mechanism in the prior art.

[0070] In order to solve the problem that when the plates are stacked and stored, the plates are adsorbed and attached to each other, so that the adsorption device cannot ensure that only a single plate is taken out. The two sides of the raw material station A are provided with blocking springs 74 for separating the plates, so that when the plates are received by the plate material transfer mechanism 2, the two sides of the plates overcome the obstruction of the blocking springs 74 and arch up. Therefore, the plates are separated by the arching deformation.

[0071] The above is a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
