[0002] In the production process of fan blades, bending and welding are key processing links, and their quality directly affects the performance and service life of the blades. The existing processing of fan blades usually adopts a step-by-step operation method, that is, first bending and then welding. This method not only has low efficiency, but also easily causes sheet deformation or positioning deviation due to multiple positioning and clamping, thus affecting the processing accuracy. Moreover, the existing bending and welding equipment often has a single function, is difficult to adapt to the processing requirements of sheets with different sizes and shapes, has poor versatility, cannot ensure the flatness of the sheet before welding, affects the subsequent welding quality, and the welding assembly has insufficient flexibility and cannot perform multi-angle welding, restricting the application range of the equipment. Therefore, the present invention provides a bending and welding device for fan blades. Summary of the Invention

[0030] Start the yielding motor 118 to drive the yielding double-head threaded screw 117 to rotate, so that the two supporting slides 110 move in the direction of approaching each other or moving away from each other, that is, the two supporting slides 110 move in the direction of approaching each other or moving away from each other. In the initial position, the two supporting slides 110 are located at the closest position. At this time, the surfaces of the two supporting slides 110 that are closest to each other are engaged, that is, at this time, the two supporting slides 110 form a supporting plane, and the supporting plane formed by the two supporting slides 110 is used to place the plate.

[0031] A positioning slide 113 is symmetrically slidably installed on the bottom plate 101, and a positioning slide 128 is also symmetrically slidably installed on the bottom plate 101. The positioning long strip 111 is fixedly installed on the corresponding positioning slide 113, and the positioning short strip 112 is fixedly installed on the corresponding positioning slide 128. The lower surfaces of the positioning long strip 111 and the positioning short strip 112 are on the same plane as the upper surface of the square frame plate 103. The positioning long strip 111 and the positioning short strip 112 are arranged at intervals. The two limiting strips 114 are located between the two positioning slides 113, and the two limiting strips 129 are located between the two positioning slides 128.

[0032] A protection component is provided on the bottom plate 101, and the protection component is used to limit the position of the long positioning strip 111 and the short positioning strip 112. The protection component includes two limit strips 114 and two limit strips 129.

The two limit strips 129 are also symmetrically slidably installed on the bottom plate 101, and the limit strips 129 are used to limit the position of the corresponding adjustment slide 128.

[0033] On the bottom plate 101, a limit double-threaded screw rod one 115 and an adjustment double-threaded screw rod one 119 are rotatably installed. The threads at both ends of the limit double-threaded screw rod one 115 respectively form a screw pair with the corresponding limit strip plates one 114, and the threads at both ends of the adjustment double-threaded screw rod one 119 respectively form a screw pair with the corresponding adjustment slide frames one 113. A limit motor one 116 and an adjustment motor one 120 are fixedly installed on the bottom plate 101. The output shaft of the limit motor one 116 is fixedly connected to the limit double-threaded screw rod one 115, and the output shaft of the adjustment motor one 120 is fixedly connected to the adjustment double-threaded screw rod one 119.

[0034] Start the limit motor one 116 to drive the limit double-threaded screw rod one 115 to rotate, so that the two limit strip plates one 114 move towards each other or move away from each other, and then the two positioning long strip plates 111 move towards each other or move away from each other. Start the adjustment motor one 120 to drive the adjustment double-threaded screw rod one 119 to rotate, so that the two adjustment slide frames one 113 move towards each other or move away from each other.

[0035] On the bottom plate 101, a limit double-threaded screw rod two 130 and an adjustment double-threaded screw rod two 132 are rotatably installed. The threads at both ends of the limit double-threaded screw rod two 130 respectively form a screw pair with the corresponding limit strip plates two 129, and the threads at both ends of the auxiliary double-threaded screw rod 142 respectively form a screw pair with the corresponding adjustment slide frames two 128. A limit motor two 131 and an adjustment motor two 133 are fixedly installed on the bottom plate 101. The output shaft of the limit motor two 131 is fixedly connected to the limit double-threaded screw rod two 130, and the output shaft of the adjustment motor two 133 is fixedly connected to the adjustment double-threaded screw rod two 132.

[0036] Start the adjustment motor two 133 to drive the adjustment double-threaded screw rod two 132 to rotate, so that the two adjustment slide frames two 128 move towards each other or move away from each other, and then the two positioning short strip plates 112 move towards each other or move away from each other. Start the limit motor two 131 to drive the limit double-threaded screw rod two 130 to rotate, so that the two limit strip plates two 129 move towards each other or move away from each other.

[0037] The protection component further includes a cross slide 123. An unlocking electric cylinder 122 is fixedly installed on the bottom plate 101. The cross slide 123 is fixedly installed at the end of the piston rod of the unlocking electric cylinder 122. Two limiting long ratchet bars one 125 and two limiting long ratchet bars two 134 are fixedly arranged on the cross slide 123. Positioning ratchet bars one 124 are fixedly installed on the limiting strip plates one 114. When the positioning ratchet bars one 124 and the corresponding limiting long ratchet bars one 125 are engaged, a ratchet mechanism one is formed. Positioning ratchet bars two 135 are fixedly arranged on the limiting strip plates two 129. When the positioning ratchet bars two 135 and the corresponding limiting long ratchet bars two 134 are engaged, a ratchet mechanism two is formed.

[0038] In the initial position, the cross slide 123 is located at the position farthest from the lower surface of the bottom plate 101. At this time, the positioning ratchet bars one 124 and the corresponding limiting long ratchet bars one 125 are engaged, and the positioning ratchet bars two 135 and the corresponding limiting long ratchet bars two 134 are engaged. Under the action of the positioning ratchet bars one 124 and the limiting long ratchet bars one 125, the two positioning ratchet bars one 124 can only move away from each other and cannot move closer to each other, that is, the two limiting strip plates one 114 can only move away from each other and cannot move closer to each other. Under the action of the limiting long ratchet bars two 134 and the positioning ratchet bars two 135, the two positioning ratchet bars two 135 can only move away from each other and cannot move closer to each other, that is, the two limiting strip plates two 129 can only move away from each other and cannot move closer to each other.

[0039] In the initial position, the two limiting strip plates two 129 are located at the closest position to each other, and the two limiting strip plates one 114 are located at the closest position to each other. The two adjusting slide frames one 113 are located at the farthest position from each other, that is, the two positioning long strip plates 111 are located at the farthest position from each other. The two adjusting slide frames two 128 are located at the farthest position from each other, that is, the two positioning short strip plates 112 are located at the farthest position from each other.

[0040] According to the size of the plate to be processed, start the limiting motor two 131 to adjust the positions of the two limiting strip plates two 129, that is, make the two limiting strip plates two 129 move away from each other, and the positioning ratchet bars two 135 move relative to the limiting long ratchet bars two 134. Start the adjusting motor one 120 to adjust the positions of the two limiting strip plates one 114, that is, make the two limiting strip plates one 114 move away from each other, and the limiting long ratchet bars one 125 move relative to the positioning ratchet bars one 124.

[0041] After completing the position adjustment of the first limit strip 114 and the second limit strip 129, place the plate to be processed on the support plane formed by the two support slides 110. When placing, make the long side of the plate basically parallel to the positioning long strip 111. Then start the first position adjustment motor 120 to make the two first position adjustment slides 113 move towards each other, that is, make the two positioning long strips 111 move towards each other. Finally, make the two sides of the plate respectively contact the corresponding positioning long strips 111. Under the action of the two positioning long strips 111, at this time, the two sides of the plate are parallel to the positioning long strips 111, and at this time, the first position adjustment slide 113 contacts the corresponding first limit strip 114. Under the action of the first limit strip 114, it is prevented that the excessive displacement of the first position adjustment slide 113 causes the deformation of the plate. Under the action of the first positioning ratchet 124 and the first long limit ratchet 125, the position of the first limit strip 114 is locked to prevent the unexpected position deviation of the first limit strip 114.

[0042] Repeat the above steps to adjust the positions of the two ends of the plate through the positioning short strip 112. Under the action of the positioning long strip 111 and the positioning short strip 112, make the plate located at the center position of the support plane formed by the two support slides 110. Under the action of the first limit strip 114 and the second limit strip 129, it is prevented that the positioning long strip 111 and the positioning short strip 112 cause the deformation of the plate. Under the action of the first positioning ratchet 124, the first long limit ratchet 125, the second long limit ratchet 134, and the second positioning ratchet 135, the positions of the first limit strip 114 and the second limit strip 129 are locked.

[0043] If it is necessary to re-adjust the positions of the first limit strip 114 and the second limit strip 129, start the unlocking cylinder 122 to drive the cross slide 123 to move downward. The first long limit ratchet 125 and the second long limit ratchet 134 on the cross slide 123 move downward synchronously. The first positioning ratchet 124 disengages from the first long limit ratchet 125, and the second positioning ratchet 135 disengages from the second long limit ratchet 134. At this time, the two first limit strips 114 can move towards each other and the two second limit strips 129 can also move towards each other, that is, at this time, starting the first limit motor 116 and the second limit motor 131 can make the first limit strip 114 and the second limit strip 129 return to the initial position. Then start the unlocking cylinder 122 to make the cross slide 123 return to the initial position. The first positioning ratchet 124 re-engages with the first long limit ratchet 125, and the second long limit ratchet 134 re-engages with the second positioning ratchet 135. Repeat the above steps to re-adjust the positions of the first limit strip 114 and the second limit strip 129 again. The axis of the flat double-headed threaded screw 139 is parallel to the axis of the second limit double-headed threaded screw 130, and the axis of the second limit double-headed threaded screw 130 is perpendicular to the axis of the first limit double-headed threaded screw 115.

Symmetrically slidably mounted leveling carriages 138 are provided on the downward moving carriage 104. The leveling rollers 141 are rotatably mounted on the corresponding leveling carriages 138. A leveling double-headed lead screw 139 is rotatably mounted on the downward moving carriage 104. The threads at both ends of the leveling double-headed lead screw 139 respectively form a screw pair with the corresponding leveling carriages 138. A leveling motor 140 is also fixedly mounted on the downward moving carriage 104. The output shaft of the leveling motor 140 is fixedly connected to the leveling double-headed lead screw 139.

[0045] Start the downward moving lead screw 137 to drive the downward moving motor 136 to rotate, which makes the downward moving carriage 104 move up and down relative to the bottom plate 101. Start the leveling motor 140 to drive the leveling double-headed lead screw 139 to rotate, which makes the two leveling carriages 138 move towards each other or move away from each other, that is, makes the two leveling rollers 141 move towards each other or move away from each other.

[0046] Place the plate to be processed on the support plane formed by the two support sliding plates 110. Then, after adjusting the position of the plate through the positioning long strip 111 and the positioning short strip 112, make the positioning long strip 111 and the positioning short strip 112 return to the initial position. Then start the leveling motor 140 to make the two leveling carriages 138 at the closest position to each other, that is, at this time the two leveling rollers 141 are at the closest position to each other and the two leveling rollers 141 are in contact. Then start the downward moving lead screw 137 to drive the downward moving carriage 104 to move downward, and the two leveling rollers 141 move downward synchronously. Finally, make the two leveling rollers 141 both contact the upper surface of the plate. Then start the leveling motor 140 to make the two leveling rollers 141 move away from each other. Under the action of the leveling rollers 141, the leveling of the plate is realized.

[0047] After stacking plates on the processed plate, repeat the above steps to make the leveling rollers 141 level the plates, so as to ensure the flatness of each stacked plate.

[0048] An auxiliary component is provided on the bottom plate 101. The auxiliary component includes two auxiliary sliding plates 143.

The output shaft of the shifting motor 148 is fixedly connected to the corresponding shifting screw rod 147. A transmission group is provided between the two shifting screw rods 147. The transmission group includes a telescopic rod 145 and two gear boxes 144. The two gear boxes 144 are respectively fixedly mounted on the corresponding auxiliary sliding frames 105. One end of the gear box 144 is fixedly connected to the corresponding shifting screw rod 147. The other end of the gear box 144 is fixedly connected to the telescopic rod 145. When the two auxiliary sliding frames 105 move towards each other or move away from each other, the telescopic rod 145 expands and contracts synchronously.

[0050] Start the auxiliary motor 146 to drive the auxiliary double-headed threaded screw rod 142 to rotate, which makes the two auxiliary sliding frames 105 move towards each other or move away from each other, and the components on the auxiliary sliding frames 105 move synchronously. Start the shifting motor 148 to drive the corresponding shifting screw rod 147 to rotate. Under the action of the transmission group, the two shifting screw rods 147 rotate synchronously, thereby making the two auxiliary sliding plates 143 move synchronously, and the auxiliary sliding plates 143 move up and down relative to the bottom plate 101.

[0051] Welding torches 156 and pressing long strip plates 157 are provided on the auxiliary sliding plates 143. The pressing long strip plates 157 are used to assist in pressing the plates. The pressing long strip plates 157 are fixedly mounted on the lower end surfaces of the auxiliary sliding plates 143. After the plates are stacked on the supporting plane formed by the two supporting sliding plates 110, start the auxiliary motor 146 to adjust the positions between the two auxiliary sliding frames 105, that is, adjust the positions between the two pressing long strip plates 157, so that the distance between the farthest surfaces of the two pressing long strip plates 157 is equal to the width of the plates. Then start the shifting motor 148 to make the two auxiliary sliding plates 143 move down synchronously, that is, make the two pressing long strip plates 157 move down synchronously to contact the upper surfaces of the plates. Under the action of the pressing long strip plates 157, the pressing and fixing of the stacked plates is realized.

[0053] After pressing the long strip 157 to complete the pressing and fixing of the stacked plates, the positioning long strip 111 and the positioning short strip 112 return to their initial positions. Then, the feeding electric cylinder I 152 is started to move the feeding slider 149 downward. The feeding electric cylinder II 154 and the position-changing motor 155 are started to adjust the position of the welding torch 156. Under the action of the feeding electric cylinder I 152, the feeding electric cylinder II 154, and the position-changing motor 155, the welding torch 156 contacts the welding position of the stacked plates. Then, the welding torch 156 is started to weld the joint position of the stacked plates. The feeding motor 150 is started to drive the feeding lead screw 151 to rotate, so that the feeding slider 153 moves relative to the feeding slider 149, and then the welding torch 156 moves synchronously. That is, the two sides of the stacked plates are welded under the action of the welding torch 156. When the welding torch 156 moves to both ends of the plates, the feeding electric cylinder II 154 is started to move the welding torch 156 along the axis of the limit double-threaded lead screw I 115, that is, to weld both ends of the plates.

[0054] The bottom plate 101 is provided with a bending assembly, which includes a bending upper mold 109 and a bending lower mold 127. The bending upper mold 109 and the bending lower mold 127 are used to bend the plate. An L-shaped lower pressing plate 102 is slidably installed on the bottom plate 101, a lower pressing motor 106 is fixedly installed on the bottom plate 101, and a lower pressing screw rod 107 is rotatably installed on the bottom plate 101. The output shaft of the lower pressing motor 106 is fixedly connected to the lower pressing screw rod 107, and the lower pressing screw rod 107 and the L-shaped lower pressing plate 102 form a spiral pair. A mounting bottom plate 108 is fixedly arranged on the lower end surface of the L-shaped lower pressing plate 102, and the mounting bottom plate 108 and the bending upper mold 127 are fixedly arranged. Bolt one is symmetrically arranged between the molds 109, the mounting base plate 108 and the bending upper mold 109 are fixedly connected by bolt one, and a mounting base plate 2 126 is also slidably installed on the base plate 101, and a supporting electric cylinder 121 is symmetrically fixedly installed on the base plate 101, and the piston rod end of the supporting electric cylinder 121 is fixedly connected to the mounting base plate 2 126, and bolt two is symmetrically arranged between the mounting base plate 2 126 and the bending lower mold 127, and the mounting base plate 2 126 and the bending lower mold 127 are fixedly connected by bolt two, and the bending upper mold 109 and the bending lower mold 127 can be easily replaced by bolt one and bolt two.

[0055] After the auxiliary component completes the welding of the superimposed plates, the auxiliary plate returns to the initial position, and the positioning long strip plate 111 and the positioning short strip plate 112 re-fix the plates, and then start the yielding motor 118 to make the two supporting slides 110 move in the direction away from each other, and finally make the distance between the two supporting slides 110 equal to the width of the lower bending mold 127, and then start the supporting electric cylinder 121 to make the mounting base plate 2 126 move upward, and the lower bending mold 127 moves upward synchronously, and finally make the upper surface of the lower bending mold 127 and the upper surface of the supporting slide 110 on the same plane, and then start the pressing motor 106 to drive the pressing screw 107 to rotate, that is, make the L-shaped lower pressing plate 102 move downward, and the mounting base plate 108 and the upper bending mold 109 move downward synchronously, and under the action of the upper bending mold 109 and the lower bending mold 127, the plate between the positioning long strip plate 111 and the positioning short strip plate 112 is pressed and bent, that is, the plate is bent.

[0056] Working principle: Place the plate on the supporting plane, and then adjust the position of the plate through the positioning component so that the plate is located at the center of the supporting plane. Under the action of the protection component, the plate is prevented from being deformed under the action of the positioning long strip 111 and the positioning short strip 112, and then the plate is leveled by the leveling component. After the leveling of the plate is completed, the positioning component is used to adjust the position of the plate again.

[0057] Then, the positioning long strip 111 and the positioning short strip 112 are returned to their initial positions, and the plate to be stacked is placed on this plate. Repeating the above steps can achieve sequential processing of the plates to be stacked. After all the plates to be stacked are processed, the positioning of the plates is achieved through the positioning component. Then, through the auxiliary component, first, the pressing long strip 157 presses and fixes both sides of the plate. Then, the positioning long strip 111 and the positioning short strip 112 are returned to their initial positions. Then, the welding gun 156 welds the joint position of the stacked plates. After the welding of the plates is completed, the positioning long strip 111 and the positioning short strip 112 are made to fix the plates again. Then, the two support sliding plates 110 are moved in the direction away from each other, that is, the bending lower die 127 is moved to directly below the stacked plates. Then, under the action of the bending component, the bending treatment of the plates is achieved.
