Referring to fig. 1 to 3, an embodiment of the present application provides a thin steel plate welding and forming apparatus, including a base 10, and a feeding mechanism 20, a rolling mechanism 30, a material poking mechanism 40, a left material stop mechanism 50, a right material stop mechanism 60, an upper material stop mechanism 70, a parallel sewing mechanism 80, a seam holding mechanism 90, a welding mechanism 100, and a liftable material stop mechanism 110, which are disposed on the base 10. In the specific processing process of manufacturing the hoop product by using the thin steel plate welding forming equipment, firstly, a blank fed into the thin steel plate welding forming equipment is conveyed to the rolling mechanism 30 through the feeding mechanism 20 for rolling, then, a stub bar of the blank rolled by the rolling mechanism 30 is continuously conveyed to one side of the splicing seam retaining mechanism 90 through the feeding mechanism 20, a tail of the blank is pushed towards one side close to the stub bar through the material shifting mechanism 40, and then, the tail of the blank is continuously pushed towards one side close to the stub bar to the other side of the splicing seam retaining mechanism 90 through the left material blocking mechanism 50, at the moment, the blank is surrounded by the left material blocking mechanism 50, the right material blocking mechanism 60, the upper material blocking mechanism 70 and the machine base 10 in the circumferential direction of the blank, the blank is surrounded by the parallel seam mechanism 80 and the material blocking mechanism 110 in the axial direction of the blank, and the stub bar and the tail of the blank are respectively located at two opposite sides of the splicing seam retaining mechanism 90.

As shown in fig. 17 and 18, the seam holding mechanism 90 includes a seam base 91 and a seam plate 92 slidably disposed on the seam base 91, two opposite sides of the seam plate 92 are respectively a plane 921 and an inclined plane 922, the material head and the material tail of the blank rounded by the rounding mechanism 30 are respectively located at two opposite sides of the seam plate 92, and pressing the blank can drive the material head and the material tail of the blank to approach each other, so that the material head and the plane 921 of the blank abut against each other, and the material tail of the blank abuts against the inclined plane 922, so that the seam plate 92 is forced to slide relative to the seam base 91 until the material head and the material tail of the blank come into contact with each other. The thin steel plate welding forming equipment can solve the problem of product quality caused by the fact that the abutted seam track of the existing equipment is difficult to fix, and therefore the product quality of hoop products is improved.

It should be noted that, as shown in fig. 17, the seam holding mechanism 90 includes a seam base 91 and a seam plate 92, wherein a slide is provided on the seam base 91 in the vertical direction, and the seam plate 92 is slidably disposed in the slide of the seam base 91, as shown in fig. 18, two opposite sides of the seam plate 92 are respectively a plane 921 and an inclined plane 922, and in a natural state, one end of the seam plate 92 close to the base 10 extends out of the seam base 91, so that a head and a tail of the blank after being rounded by the rounding mechanism 30 are blocked at two opposite sides of the seam plate 92, when the blank is pressed, the head and the tail of the blank have a movement tendency close to each other, so that the head and the plane 921 of the blank can abut against each other, the tail of the blank abuts against the inclined plane 922, and the seam plate 92 is forced to slide toward the side away from the base 10 relative to the seam base 91 until one end of the seam plate 92 close to the base 10 retracts into the seam base 91, and at this time, the head and the tail of the blank and the tail of the blank can no longer be separated by the seam plate 92 to be in close contact with each other.

In the above process, since the stub bar of the blank abuts against the plane 921, the stub bar of the blank has only a force F in the direction perpendicular to the plane 921 (i.e. in the horizontal direction) on the seaming panel 92 _{Head with a rotatable shaft} Since the tail of the blank abuts against the inclined plane 922, the force F of the tail of the blank acting on the seaming panel 92 _Tail Can be divided into a first component F in the horizontal direction ₁ And a second component F in the vertical direction ₂ The force that the end of the joint plate 92 close to the machine base 10 in the natural state extends out of the joint base 91 is denoted as F ₀ When the second component of force F ₂ Greater than so that the force F ₀ During the time, piece board 92 alright be slided by one side that the material tail jack-up orientation of blank deviates from frame 10, until piece board 92 is close to in the one end withdrawal piece base 91 of frame 10, at this moment, the stub bar and the material tail of blank can merge in plane 921 orthographic projection department on frame 10, thereby make and adopt this sheet steel welding former to carry out staple bolt product processing, the actual position of the piece that forms between the stub bar of blank and the material tail is fixed all the time, and then make the piece orbit can avoid the partial welding with the coincidence of predetermined welder 103 orbit, effectively improve the product quality of staple bolt product.

It is worth noting how to make the end of the patchwork board 92 close to the machine base 10 extend out of the patchwork base 91 (or the force F is applied) under the natural condition ₀ Specifically, who provides it), those skilled in the art should be able to make appropriate selections and designs according to the actual situation, and no particular limitation is made herein. For example, in this embodiment, the fourth cylinder 93 is disposed on the seam splicing plate 92, and an air pressure with a suitable size is disposed on an air intake circuit of the fourth cylinder 93 in advance, so that the fourth cylinder 93 becomes a spring with an approximately constant elastic force to press the seam splicing plate 92, but in other embodiments, a spring with an adjustable size may also be directly disposed on the seam splicing plate 92, or alternatively, the size may also be directly adjusted depending on the self weight of the seam splicing plate 92.

In addition, the inclination angle α of the inclined plane 922 should not be too small to avoid the space between the inclined plane 922 and the machine base 10 being too small, which makes the tail of the blank difficult to enter therein, and of course, the inclination angle α of the inclined plane 922 should not be too large to avoid the second component force F ₂ Too small results in difficulty in lifting the patchwork panel 92 by pressing the blank. Regarding the actual size of the inclined angle α of the inclined plane 922, those skilled in the art should be able to make reasonable selection and design according to the actual situation, and no particular limitation is made here. Illustratively, as shown in fig. 18, in the present embodiment, the inclination angle α of the slope 922 is 20 °.

As shown in fig. 14 to 16, the welding mechanism 100 includes a displacement table 102 and a welding torch 103 fixedly disposed on the displacement table 102, and the displacement table 102 is configured to drive the welding torch 103 to move relative to the base 10, so that an orthographic projection of the welding torch 103 on the base 10 coincides with an orthographic projection of the plane 921 on the base 10.

It should be noted that, as shown in fig. 14 to 16, the welding mechanism 100 includes a displacement table 102 and a welding gun 103, wherein the welding gun 103 is disposed along a vertical direction, and the displacement table 102 can drive the welding gun 103 to move relative to the base 10, so that an orthographic projection of the welding gun 103 on the base 10 coincides with an orthographic projection of the plane 921 on the base 10, so that a welding track of the welding gun 103 coincides with a seam splicing track formed between a stub bar and a tail bar of a blank, thereby ensuring a welding effect during welding. The displacement table 102 may be a displacement table 102 capable of adjusting the position in an x-uniaxial direction (i.e., the horizontal direction), may also be a displacement table 102 capable of adjusting the position in an x-y biaxial direction (i.e., the horizontal direction and the vertical direction), so as to correspondingly increase the function of adjusting the distance between the welding gun 103 and the seam, and may also be a displacement table 102 capable of adjusting the position in an x-y-z triaxial direction (i.e., the horizontal direction, the vertical direction, and the axial direction of the blank), so as to correspondingly increase the function of adjusting the distance between the welding gun 103 and the seam and realizing the welding of the welding gun 103 along the axial direction of the blank.

As shown in fig. 2, the feeding mechanism 20 is configured to convey the blank fed into the thin steel plate welding and forming apparatus to the rounding mechanism 30 for rounding, and convey the stub bar of the blank rounded by the rounding mechanism 30 to the side of the plane 921. Specifically, as shown in fig. 2 and fig. 4, the feeding mechanism 20 includes a first pinch roller set 21 and a second pinch roller set 22 to form a conveying passage through the first pinch roller set 21 and the second pinch roller set 22, wherein, as shown in fig. 4, the first pinch roller set 21 is taken as an example for explanation, two first mounting seats 214 are provided on the machine base 10, a pinch roller 212 is rotatably mounted between the two first mounting seats 214, and the pinch roller 212 is driven by a motor reducer 211, and the second pinch roller set 22 is different from the first pinch roller set 21 in that the second pinch roller set 22 transmits power by a sprocket 213 mounted on the motor reducer 211 and a chain mounted on the sprocket 213, so that the first pinch roller set 21 and the second pinch roller set 22 share one motor reducer, thereby reducing the volume of the equipment and saving the cost of the equipment.

It should be noted that, as shown in fig. 2, in order to facilitate feeding the blank into the sheet steel welding forming apparatus, a first guide plate 24 is provided before the first pinch roll set 21, the first guide plate 24 includes two first guide plates 24, and the distance between the two first guide plates 24 is gradually reduced along the direction from the first pinch roll set 21 to the second pinch roll set 22, so as to facilitate feeding of the sheet steel welding forming apparatus, and a second guide plate 25 is provided between the first pinch roll set 21 and the second pinch roll set 22, so that the blank passing through the first pinch roll set 21 is conveyed to the second pinch roll set 22 through the second guide plate 25.

On the basis, as shown in fig. 2 and 5, the feeding mechanism 20 further comprises a pinch roller assembly 23, so that the blank is pinched by the pinch roller assembly 23 in cooperation with the first pinch roller set 21. Specifically, as shown in fig. 2 and 5, two second installation seats 235 are slidably arranged on the machine base 10, a pressing roller 232 is rotatably installed between the two second installation seats 235, a fixed seat 234 is arranged on the second installation seat 235, an output shaft of the first air cylinder 231 extends into the fixed seat 234 and can be fixedly connected with the second installation seat 235 through a lock nut 233, so that the first air cylinder 231 is driven to drive the second installation seat 235 to move along the vertical direction, the distance between the pressing roller 232 and the pinch roller 212 is correspondingly adjusted, blanks with different thicknesses t can be smoothly passed through the space between the pressing roller 232 and the pinch roller 212, and the pressing roller 232 can press blanks with different thicknesses t.

As shown in fig. 6 and 7, the rounding mechanism 30 includes a rounding base 31, and a lifting plate 32 and a supporting wedge 33 slidably disposed on the rounding base 31, the lifting plate 32 is provided with a rolling member 321 and two first bearing seats 322, a rounding roller 323 is installed between the two first bearing seats 322, the supporting wedge 33 abuts against the rolling member 321, and the supporting wedge 33 is driven to slide relative to the rounding base 31, so that the rolling member 321 rolls along a wedge surface of the supporting wedge 33, and the lifting plate 32 is forced to slide relative to the rounding base 31 to correspondingly adjust a vertical height of the rounding roller 323.

It should be noted that, as shown in fig. 6 and 7, the rounding mechanism 30 includes a rounding base 31 and a lifting plate 32, wherein the lifting plate 32 is provided with two first bearing seats 322, and a rounding roller 323 is installed between the two first bearing seats 322, as shown in fig. 2, since the vertical height of the rounding roller 323 is higher than the vertical height of the feeding mechanism 20, the blank conveyed to the rounding mechanism 30 by the feeding mechanism 20 can change its original moving direction (i.e. tilt upward by a certain angle) when passing through the rounding roller 323, thereby achieving the rounding processing of the blank, so that the specific diameter of the blank rounding can be adjusted by changing the vertical height of the rounding roller 323 (essentially changing the height difference between the rounding roller 323 and the feeding mechanism 20).

For this purpose, as shown in fig. 6 and 7, the rounding mechanism 30 further includes a supporting wedge 33, wherein the rounding base 31 is provided with a first guide rail 31a along the vertical direction and a second guide rail 31b along the axial direction of the blank, the lifting plate 32 is slidably disposed on the first guide rail 31a of the rounding base 31, the supporting wedge 33 is slidably disposed on the second guide rail 31b of the rounding base 31, the lifting plate 32 is further provided with a rolling member 321, the supporting wedge 33 abuts against the rolling member 321, when the supporting wedge 33 is driven to slide relative to the rounding base 31, the rolling member 321 can roll along a wedge surface of the supporting wedge 33, so that the lifting plate 32 is forced to slide relative to the rounding base 31 to correspondingly adjust the vertical height of the rounding roller 323, thereby correspondingly adjusting the specific diameter of the blank.

In order to avoid the situation that the lifting plate 32, the first bearing seat 322 and the rolling roller 323 are too heavy, which causes the rolling member 321 to be dull when rolling on the supporting wedge 33, as shown in fig. 6 and 7, the rolling mechanism 30 further includes two mounting rods 34 fixedly disposed on the rolling base 31, each mounting rod 34 is sleeved with an elastic member 341, two ends of the elastic member 341 are respectively connected with the rolling base 31 and the lifting plate 32, so as to support the lifting plate 32 through the elastic member 341, and the elastic potential energy accumulated by the elastic member 341 can be changed along with the position change of the lifting plate 32 relative to the supporting wedge 33. Specifically, when the distance between the lifting plate 32 and the supporting wedge 33 is small (or the vertical height of the rounding roller 323 is low), the elastic member 341 receives a large pressing action and accumulates a large elastic potential energy, which provides a large elastic force, thereby facilitating the movement of the rolling member 321 toward the high point of the supporting wedge 33; when the distance between the lifting plate 32 and the supporting wedge 33 is large (or the vertical height of the rounding roller 323 is high), the elastic member 341 receives a small pressing action and accumulates a small amount of elastic potential energy, and the elastic force provided by the elastic member is easily overcome, so that the rolling member 321 can move toward the low point of the supporting wedge 33.

It should be noted that, as shown in fig. 7, in order to facilitate the acting force of the elastic element 341 to act on the lifting plate 32, the first bearing seat 322 and the rolling roller 323, a connecting support 342 is disposed between the lifting plate 32 and the first bearing seat 322, the connecting support 342 is an L-shaped structure, two opposite sides of one of the folding arms of the L-shaped structure are respectively fixedly connected with the lifting plate 32 and the first bearing seat 322, and the other folding arm of the L-shaped structure is fixedly connected with the elastic element 341. In addition, as shown in fig. 6 and 7, in order to facilitate driving of the supporting wedge 33, a ball nut 331 is fixedly connected to one side of the supporting wedge 33, a screw hole is formed in the rolling base 31, a screw rod 332 is fitted into the screw hole and connected to the first hand wheel 333, and the ball nut 331 is fitted over the screw rod 332 so that an operator can control the supporting wedge 33 to slide along the second guide rail 31b by rotating the first hand wheel 333.

As shown in fig. 2, the material shifting mechanism 40 is used for shifting the tail of the blank material to the side close to the stub bar to the side where the inclined plane 922 is located. Specifically, as shown in fig. 2, fig. 8 and fig. 9, the material shifting mechanism 40 includes two second bearing seats 42 slidably disposed on the machine base 10, a bearing 43 is installed between the two second bearing seats 42, a material shifting fork 431 is fixedly disposed on the bearing 43, and the bearing 43 is driven to rotate relative to the second bearing seats 42, so as to drive the material shifting fork 431 to rotate toward a side close to the seam holding mechanism 90.

It should be noted that, as shown in fig. 2, the aforesaid pinch roll assembly 23 can cooperate with the first pinch roll set 21 to pinch the blank, and the material ejecting mechanism 40 can also cooperate with the second pinch roll set 22 to pinch the blank, so that the original moving direction of the blank (i.e. the blank is inclined upward by a certain angle) can be changed rapidly and obviously when the blank passes through the rounding roll 323. As shown in fig. 8 and 9, when the microswitch 48 on the material shifting mechanism 40 captures that the tail of the blank has passed through between the material shifting mechanism 40 and the second pinch roller set 22, the material shifting mechanism 40 does not need to continuously cooperate with the second pinch roller set 22 to press the blank, and at this time, the second bearing seat 42 can slide (for example, move down by a thickness t of the blank) in the vertical direction under the action of the second air cylinder 44 (and the air cylinder connecting seat 41), so that the tail of the blank is shifted toward the side close to the head to the side where the inclined plane 922 is located by the material shifting mechanism 40.

As to how the material shifting mechanism 40 shifts the tail of the blank toward the side close to the material head, as shown in fig. 8 and 9, a bearing 43 is installed between two second bearing seats 42, as is well known, the bearing 43 is divided into an inner ring and an outer ring, when the third cylinder 45 drives the bearing 43 to rotate through a rack 47 and a gear 46, the inner ring of the bearing 43 rotates, and the outer ring of the bearing 43 is fixed, for this purpose, a material shifting fork 431 is fixedly arranged on the bearing 43, and actually, the material shifting fork 431 is fixedly connected with the inner ring of the bearing 43, so that the third cylinder 45 is driven to drive the inner ring of the bearing 43 and the material shifting fork 431 to rotate, thereby the tail of the blank is shifted toward the side close to the material head through the material shifting fork 431.

As shown in fig. 1 to 3 and 10 to 12, the left material stop mechanism 50 and the right material stop mechanism 60 are respectively configured to abut against the left and right sides of the blank, and the upper material stop mechanism 70 is configured to abut against the top of the blank and press the blank. Specifically, as shown in fig. 10, the left striker 50 includes a first base 51, a third guide rail 52 is disposed on the first base 51, and a left baffle 53 is slidably disposed on the third guide rail 52, for example, in the present embodiment, the left baffle 53 is driven by a first motor 54 and transmits power through a first synchronous belt transmission assembly 55 and a first lead screw slider assembly 56; as shown in fig. 11, the right blocking mechanism 60 includes a second base 61, a fourth guide rail 62 is disposed on the second base 61, and a right blocking plate 63 is slidably disposed on the fourth guide rail 62, for example, in the present embodiment, the right blocking plate 63 is driven by a second hand wheel 64 and transmits power through a second lead screw slider assembly 65 and a connecting seat 66; as shown in fig. 12, the upper baffle mechanism 70 includes an upper baffle 73, the upper baffle 73 is driven by the second motor 71, and transmits power through the third screw rod slider assembly 72, in addition, an adjustable baffle 74 may be disposed on one side of the upper baffle 73 close to the liftable baffle, and the adjustable baffle 74 may slide relative to the upper baffle 73, so as to flexibly change the actual length of the upper baffle mechanism 70 along the axial direction of the blank, thereby being suitable for performing edge welding on blanks with different widths.

The existing equipment in the industry also has the following product quality problems: after blank rolling and before welding, a tiny gap exists between the stub bar and the stub bar, and the intermittent weld penetration occurs at the abutted seam with the gap. Therefore, in the application, after the stub bar and the butt of the blank are spliced, the first motor 54 drives the left material blocking mechanism 50, the second hand wheel 64 drives the right material blocking mechanism 60 (which is not moved after being adjusted in place) and the second motor 71 drives the upper material blocking mechanism 70, so that a certain elastic positive pressure can be ensured to exist between the stub bar and the butt of the blank on the splicing section all the time, and the elastic positive pressure can promote the stub bar and the butt of the blank to be always kept in effective contact on the splicing section, thereby eliminating a tiny gap between the stub bar and the butt.

The existing equipment in the industry also has the following product quality problems: in the blank rolling and welding process, the edge part of the blank cannot be aligned, and after the welding profiling is carried out, when concrete is poured in the pipe die and passes through a centrifugal process section, a gap is formed between the unaligned part and the pipe die, so that slurry leakage is caused. Therefore, in the present application, as shown in fig. 13 to 17, the parallel sewing mechanism 80 includes a slide rail base 81 and a push plate 82 slidably disposed on the slide rail base 81, the push plate 82 is driven to slide relative to the slide rail base 81, and can drive the blank to move toward a side close to the liftable material blocking mechanism 110, so that the parallel sewing mechanism 80 and the liftable material blocking mechanism 110 respectively abut against the front and rear sides of the blank, thereby achieving alignment of the edge of the blank in the axial direction of the blank.

Illustratively, as shown in fig. 13 and 16, in the present embodiment, the push plate 82 is driven by a third motor 821 and transmits power through a second synchronous belt transmission assembly 822 and a fourth lead screw slider assembly 823. It should be noted that, when the aforementioned displacement table 102 is a displacement table 102 in an x-single axis direction and a displacement table 102 in an x-y two-axis direction, as shown in fig. 14, the displacement table 102 may be fixed on a slide block (or a push plate 82) of a fourth lead screw slide block assembly 823 of the stitching mechanism 80 through a welding base 101, so that the welding mechanism 100 and the stitching mechanism 80 share a set of driving mechanisms (i.e., the third motor 821, the second synchronous belt transmission assembly 822 and the fourth lead screw slide block assembly 823), thereby reducing the volume of the apparatus and saving the cost of the apparatus.

Because the seam holding mechanism 90 interferes with the welding mechanism 100, when the welding mechanism 100 performs welding, (when the seam holding mechanism 90 is not fixed to the welding mechanism 100) the seam holding mechanism 90 can be retracted towards the side away from the liftable material blocking mechanism 110 in advance, or (as shown in fig. 14, when the seam holding mechanism 90 is fixed to the welding mechanism 100 and the welding mechanism 100 is located at the side close to the liftable material blocking mechanism 110) the seam holding mechanism 90 can be retracted towards the side away from the liftable material blocking mechanism 110 synchronously, and at the moment, the limiting effect along the vertical direction provided by the seam holding mechanism 90 on the head and tail of the blank disappears. For this purpose, as shown in fig. 13 to 17, the joint compound mechanism 80 further includes a vertical sliding table 83 fixedly disposed on the sliding rail base 81, and two laminated boards 84 slidably disposed on the vertical sliding table 83, the two laminated boards 84 are respectively located at two opposite sides of the joint maintaining mechanism 90, and the laminated boards 84 are driven to press the stub bar and the tail of the blank against the machine base 10.

It should be noted that, as shown in fig. 13 and 16, the seaming mechanism 80 further includes a vertical sliding table 83 and two laminated plates 84, and the two laminated plates 84 extend in the axial direction of the blank, so that after the stub bar and the stub bar of the blank are spliced, the stub bar and the stub bar of the blank are pressed by the two laminated plates 84, so that the butt contact of the stub bar and the stub bar of the blank is always maintained. Illustratively, as shown in fig. 16, in the present embodiment, a connecting bracket 841 is disposed between the vertical sliding table 83 and the laminated board 84 to correspondingly adjust the distance between the laminated board 84 and the machine base 10 through the sliding of the connecting bracket 841 on the vertical sliding table 83, wherein the connecting bracket 841 is in a triangular structure, one of the right-angled sides of the triangular structure is slidably connected with the vertical sliding table 83, and the other right-angled side of the triangular structure is fixedly connected with the laminated board 84 to improve the connection strength between the connecting bracket 841 and the laminated board 84.

The existing equipment in the industry also has the following product quality problems: in the blank edge rolling process, the phenomenon of overlapping of the stub bar and the stub bar is easy to occur, so that insufficient solder exists during welding, and cracking occurs during subsequent over-pressing process to cause waste. For this reason, in the present application, as shown in fig. 17, the thickness of the blank is t, and the distance between the laminated board 84 and the top surface of the base 10 (i.e., the top surface of the middle cover plate 11) and the distance between the patchwork base 91 and the top surface of the base 10 are d, and satisfy the relationship: t < d < 2t, for example, d may be 1.3t to 1.6t when actually set, so that when the stub bar of the blank passes through the gap between the laminated board 84 located on the side where the plane 921 is located and the top surface of the base 10 and the gap between the seam pedestal 91 and the top surface of the base 10 in sequence and moves towards the side close to the stub bar, and when the stub bar of the blank passes through the gap between the laminated board 84 located on the side where the inclined plane 922 is located and the top surface of the base 10 and the gap between the seam pedestal 91 and the top surface of the base 10 in sequence and moves towards the side close to the stub bar, through the mutual cooperation between the laminated board 84, the seam pedestal 91 and the base 10, the inter-layer movement between the stub bar and the stub bar of the blank can be limited, and the overlapping phenomenon of the stub bar and the stub bar of the blank is avoided.

For example, as shown in fig. 19, in the present embodiment, the liftable material blocking mechanism 110 includes a third base 111 and a front baffle 112 slidably disposed on the third base 111, when it is required to cooperate with the push plate 82 of the seaming mechanism 80, the front baffle 112 can be lifted in advance, and when it is not required to cooperate with the push plate 82 of the seaming mechanism 80, the front baffle 112 can be kept in a standby state in which the top surface thereof does not exceed the top surface of the stand 10. Specifically, the front barrier 112 is driven by a fifth cylinder 113 and transmits power through a connection plate 114, and a third guide plate 115 is further provided on the third base 111 to guide and limit the movement direction of the front barrier 112 through a guide groove on the third guide plate 115.

In summary, the specific processing process of manufacturing the hoop product by using the thin steel plate welding forming equipment mainly comprises the following steps: when the blank with the fixed length is conveyed to the thin steel plate welding forming equipment, the blank firstly passes through a first guide plate 24 at an inlet, the first pinch roller group 21 is matched with a pressing roller assembly 23 above the first pinch roller group 21 to press the blank, and a motor reducer 211 of the first pinch roller group 21 is startedMoving and driving the blank to be conveyed forwards; the blank continuously passes through the second guide plate 25 to reach the second pinch roller set 22, the second pinch roller set 22 is matched with the material poking mechanism 40 above the second pinch roller set to tightly press the blank, and the blank is conveyed in a relay mode (the second pinch roller set 22 obtains power from a motor speed reducer 211 of the first pinch roller set 21 through a chain wheel 213 and a chain); the stub bar of the blank continuously touches the rounding roller 323 of the rounding mechanism 30 forwards, the stub bar of the blank deflects upwards under the action of the rounding roller 323, and the second pinch roller group 22 continuously conveys the blank so as to realize the rounding processing on the blank; the stub bar of the blank rounded by the rounding mechanism 30 enters the gap at the right side of the laminated board 84, and the stub bar of the blank is blocked by the plane 921 of the splicing board 92 when going forward; the second pinch roll group 22 continues to convey the blank to the tail to pass through the second pinch roll group 22, when the microswitch 48 catches that the tail of the blank passes through the second pinch roll group 22, the bearing 43 of the material shifting mechanism 40 moves downwards by a certain height (for example, the thickness t of one blank) under the action of the second air cylinder 44, then the material shifting fork 431 rotates clockwise by a certain angle (for example, 270 degrees) under the action of the third air cylinder 45, the gear 46 and the rack 47, the tail clamped between the second pinch roll group 22 and the material shifting mechanism 40 is shifted to the left side of the laminated board 84, and the left material stopping mechanism 50 is started to further push the tail to a gap on the left side of the laminated board 84; the upper material stopping mechanism 70 is pressed down to just touch the blank, then the push plate 82 of the seaming mechanism 80 pushes the blank towards one side close to the liftable material stopping mechanism 110 under the pushing of the third motor 821, the second synchronous belt transmission component 822 and the fourth screw rod sliding block component 823, the front baffle 112 of the liftable material stopping mechanism 110 is lifted, the push plate 82 positioned at the inner side pushes the blank to a distance of exactly one plate width from the front baffle 112 positioned at the outer side, and then the blank is stopped (the actual distance can be left with a certain margin, for example, one plate width is + 1-2 mm), so that the blank completes the blank edge alignment process under the action of the push plate 82 positioned at the inner side and the front baffle 112 positioned at the outer side; the distance between the preset laminated board 84 and the middle cover plate 11 and the distance d between the abutted seam base 91 and the middle cover plate 11 satisfy the relation: t < d < 2t to prevent the stub bar and the tail of the blank from being stacked in the splicing process, the upper material retaining mechanism 70 is pressed down continuously, the stub bar of the blank is pressed tightly against the plane 921 on the right side of the splicing plate 92, and the tail of the blank is pressed tightlyIs pressed against the inclined plane 922 on the left side of the joint plate 92, and the acting force F of the tail of the blank on the joint plate 92 along with the continuous pressing of the upper material stopping mechanism 70 _Tail Gradually increasing, the butt joint plate 92 is jacked up by the tail of the blank to be attached to the stub bar, and the left material stopping mechanism 50 is driven by the first motor 54, the right material stopping mechanism 60 is driven by the second hand wheel 64 (the material stopping mechanism is not moved after being adjusted in place) and the elastic positive pressure applied by the upper material stopping mechanism 70 is driven by the second motor 71 to realize tight contact, so that a tiny gap between the tail of the stub bar is eliminated; after the splicing plate 92 is jacked up, elastic pressing is still kept on the material tail of the blank, then the laminated plate 84 is pressed down, and the material head and the material tail of the blank which are aligned at the edges, have no staggered layers and are spliced in a seamless state are simultaneously pressed; setting the welding gun 103 right above the plane 921 of the seam splicing plate 92 in advance, starting the seam doubling mechanism 80 to retreat to drive the welding gun 103 to retreat, and performing welding while retreating until welding is finished;
