Description

Technical Field

[0001] The invention relates to the technical field of metal plate processing, in particular to a processing system for metal plates of an electric oven. Background Art

[0002] An electric oven is a household appliance used for cooking food. It generates heat through electricity to heat food and can be used to bake meat, vegetables, bread and other ingredients. Figure 10 As shown, the main body of the electric oven is welded by trapezoidal metal plates and flat metal plates on the front and rear sides and bent metal plates symmetrically distributed on the left and right sides. The welded main body has high strength and excellent high temperature resistance.

[0003] The actual method of welding the main part of the electric oven is mainly to use a positioning device to position the trapezoidal metal plate, the straight metal plate and the two bent metal plates respectively, and then combine the positioned trapezoidal metal plate, the straight metal plate and the two bent metal plates by pushing the two bent metal plates, and the welders manually weld the joints of the combined metal plates, so that the four metal plates are welded into the main part of the electric oven.

[0004] Although the above welding method can quickly weld the assembled metal plates, since the bent metal plates are thin plates, and the above combination method is achieved by pushing two bent metal plates, this combination method is likely to cause the bent metal plates to deform as a whole during the process of pushing the bent metal plates, resulting in uneven joints between the bent metal plates and the trapezoidal metal plates and the straight metal plates, thereby reducing the welding accuracy. In addition, since the above welding method adopts manual welding, it is impossible to ensure that the distance between the welding gun and the joints of the trapezoidal metal plates, the straight metal plates and the two bent metal plates is consistent during the welding process, thereby affecting the quality of the weld and easily causing uneven welds.

DETAILED DESCRIPTION

[0031] The following embodiments of the present invention are described in detail. The embodiments described below are exemplary and are only used to explain the present invention, and are not to be construed as limiting the present invention. Where specific techniques or conditions are not specified in the embodiments, the techniques or conditions described in the literature in the art or in the product specifications shall be followed.

[0032] See Figure 1-Figure 2A processing system for metal sheets of an electric oven includes a bottom support plate 1, two groups of horizontal slide rails 11 are symmetrically arranged on the top of the bottom support plate 1, a center plate 12 is fixed on the top of the bottom support plate 1, each group of the horizontal slide rails 11 is connected to a clamping mechanism 2 through a horizontal slider, two groups of pushing mechanisms 3 are symmetrically arranged on the top of the bottom support plate 1, and a limiting mechanism 4 is arranged on the top of the bottom support plate 1 and on the front and rear sides of the center plate 12 through a square column. The top of the bottom support plate 1 is connected to a welding mechanism 5, which is connected to the two limiting mechanisms 4.

[0033] The present invention positions the metal plates of the electric oven body in sequence through the clamping mechanism 2 and the limiting mechanism 4, and pushes the positioned bent metal plates through the pushing mechanism 3, so that the metal plates of the electric oven body are combined. At the same time, the welding mechanism 5 welds the joints of the two adjacent metal plates in sequence, so that the main body of the electric oven is quickly welded and formed.

[0034] Specifically, the operator first places the bent metal plate on the clamping mechanism 2 and pushes the bent metal plate from back to front. After the pushing is completed, the clamping mechanism 2 is controlled to clamp and position the bent metal plate, and ensure that the bent metal plate is in a vertical state. Then the operator places the straight metal plate and the trapezoidal metal plate on the rear limiting mechanism 4 and the front limiting mechanism 4 in turn. After all metal plates are placed, the pushing mechanism 3 is controlled to push the bent metal plate from the left and right sides respectively, so that the straight metal plate and the trapezoidal metal plate are further pushed by the bent metal plate to complete the combination of all metal plates. After all metal plates are combined, the welding mechanism 5 is controlled to weld the joints of all metal plates. After welding is completed, the formed metal plates are taken out from the top.

[0035] See Figure 3-Figure 5 The default clamping mechanism 2 includes an L-shaped movable plate 21 fixed to the top of the horizontal slider on the same side, and clamping members 22 are symmetrically arranged on the front and back of the top of the horizontal section of the L-shaped movable plate 21. A clamping member 22 is also provided on the rear side of the vertical section of the L-shaped movable plate 21. All clamping members 22 are connected to a synchronization structure together; the clamping member 22 includes a horizontal frame 221 fixed to the L-shaped movable plate 21 through an upper extension rod, and vertical through grooves are symmetrically opened on the horizontal frame 221, and a vertical clamping plate 222 connected to the synchronization structure is slidably connected in each vertical through groove.

[0036] The synchronous structure includes an extension plate 211 that is symmetrically fixed on the horizontal section of the L-shaped movable plate 21. A motor 212 is installed on the top of the extension plate 211 close to the vertical plate 31 through a motor seat. A rotating matching plate 213 is fixed on the top of the extension plate 211 away from the vertical plate 31. A bidirectional threaded rod 214 is connected between the output end of the motor 212 and the rotating matching plate 213. An L-shaped connecting plate 215 is symmetrically threaded on the bidirectional threaded rod 214. The L-shaped connecting plate 215 is fixedly connected to the vertical clamping plate 222.

[0037] The clamping mechanism 2 is used to position the bent metal plate, thereby ensuring that the bent metal plate is in a vertical state, and by means of synchronous clamping by the two clamping members 22 at the bottom cooperating with a clamping member 22 on the front side, it can further ensure that the bent metal plate is in a vertical state, and a synchronous structure is used to synchronously control all the clamping members 22 for clamping, thereby making positioning, clamping and releasing faster, and facilitating the subsequent release of the positioning state of all metal plates that have been welded.

[0038] Specifically, the operator first places the two bent metal plates on the top of the two horizontal frames 221 on the lower left and right sides and limits them by the vertical clamping plates 222. At this time, first ensure that the L-shaped movable plate 21 together with the horizontal slider is located on the side of the horizontal slide rail 11 close to the pushing mechanism 3. At this time, the upper parts of the two bent metal plates are in a position close to each other. Then control the motor 212 to drive the bidirectional threaded rod 214 to rotate. As the bidirectional threaded rod 214 rotates, the two L-shaped connecting plates 215 will drive all the vertical clamping plates 222 to move synchronously toward the bent metal plates at the corresponding positions, so that the bent metal plates are clamped by the vertical clamping plates 222, and ensure that the clamped bent metal plates are in a vertical state.

[0039] See Figure 2 、 Figure 4 and Figure 6 The limiting mechanism 4 includes a fixed plate 41 fixed on the top of the square column, and two groups of limiting plates 411 are fixed symmetrically on the top of the fixed plate 41. Each group of limiting plates 411 consists of two limiting plates 411 symmetrically distributed front and back, and a pressing component 42 is provided on the sides of the two limiting plates 411 away from the center plate 12.

[0040] The pressing member 42 includes a restraining rod 421 fixed to the front side of the limiting plate 411, and a longitudinal sliding sleeve 422 is sleeved on the restraining rod 421. A square plate 423 is fixed to the end of the restraining rod 421 away from the limiting plate 411, and a longitudinal spring is connected between the square plate 423 and the longitudinal sliding sleeve 422. A bent pressure plate 424 is fixed to the top of the longitudinal sliding sleeve 422, and a pushing structure is provided at the bottom of the longitudinal sliding sleeve 422; the pushing structure includes a lower extension rod 425 fixed to the bottom of the longitudinal sliding sleeve 422, and a pushing block 426 is fixed to the side of the bottom of the lower extension rod 425 away from the center plate 12; a connecting rod 216 is fixed to the position corresponding to each pushing block 426 on the L-shaped movable plate 21, and a pushing block 217 that cooperates with the pushing block 426 is fixed to the end of the connecting rod 216 close to the center plate 12.

[0041] The limiting mechanism 4 is used to limit and further position the straight metal plate and the trapezoidal metal plate, so that the straight metal plate and the trapezoidal metal plate are in a vertical state through the pressing member 42 and the limiting plate 411, thereby ensuring the welding accuracy of the combined straight metal plate and the trapezoidal metal plate and the bent metal plate during welding. At the same time, the pushing block 217 is used to drive the pressing member 42 to press and position the straight metal plate and the trapezoidal metal plate, which can ensure that the straight metal plate and the trapezoidal metal plate are in a vertical state after the pressing and positioning are completed, thereby further ensuring the welding accuracy of the welding mechanism 5.

[0042] Specifically, after the bent metal plate is positioned, the operator places the straight metal plate and the trapezoidal metal plate on the rear fixing plate 41 and the front fixing plate 41 respectively, and the limiting plate 411 limits the straight metal plate and the trapezoidal metal plate. When the control pushing mechanism 3 is used to push the bent metal plate, the L-shaped movable plate 21 will move together with the bent metal plate, and the connecting rod 216 will move toward the straight metal plate and the trapezoidal metal plate together with the pushing block 217. Then the pushing block 217 will push the pushed block 426, and the pushed block 426 will drive the longitudinal sliding sleeve 422 to move toward the square close to the straight metal plate or the trapezoidal metal plate, thereby causing the bending pressure plate 424 to press the straight metal plate or the trapezoidal metal plate, and cooperate with the limit plate 411 to press the straight metal plate or the trapezoidal metal plate to a vertical state. At this time, since the straight metal plate, the trapezoidal metal plate and the two bent metal plates are in a vertical state, the joint positions of the four are precisely fitted.

[0043] See Figure 3-Figure 4The pushing mechanism 3 includes a vertical plate 31 fixed to the top of the bottom support plate 1, and a cylinder 311 is installed on the side of the vertical plate 31 near the L-shaped movable plate 21. The pushing end of the cylinder 311 is fixed to a collecting plate 312, and two groups of pushing members are symmetrically arranged on the collecting plate 312. Each group of pushing members consists of an upper pushing member 32 and a lower pushing block 313; the pushing mechanism 3 also includes an elastic telescopic rod fixed to the side of the center plate 12 near the corresponding collecting plate 312, and a blocking frame 314 is fixed on the telescopic end of the elastic telescopic rod, and a blocking structure is symmetrically arranged on the blocking frame 314.

[0044] The pushing member 32 includes a horizontal sliding column 321 that slides through the collecting plate 312, and a circular plate 322 is fixed to the end of the horizontal sliding column 321 close to the cylinder 311, and a tension spring is connected between the circular plate 322 and the collecting plate 312, and the end of the horizontal sliding column 321 away from the cylinder 311 is hinged to a support plate 323; the blocking structure includes a support rod 315 hinged to the top of the blocking frame 314, and a torsion spring is provided at the hinge between the support rod 315 and the blocking frame 314 for keeping the support rod 315 vertical, and a support block 316 is fixed to the top of the support rod 315 and on the side close to the collecting plate 312, and an L-shaped lower extension rod 317 is fixed to the bottom of the blocking frame 314.

[0045] The pushing mechanism 3 is used to push the bent metal plate that has been positioned, so that the two bent metal plates can simultaneously push the straight metal plate and the trapezoidal metal plate to complete the positioning of the straight metal plate and the trapezoidal metal plate. At the same time, when the pushing member 32 pushes the bent metal plate, the blocking structure can continue to elastically block and protect the bent metal plate, thereby avoiding the deformation of the bent metal plate during the process of the pushing member 32 pushing the bent metal plate.

[0046] Specifically, after the straight metal plate and the trapezoidal metal plate are placed, the control cylinder 311 drives the collection plate 312 to move toward the center plate 12. When the collection plate 312 moves a certain distance, the support plate 323 will first contact the upper plate part of the bent metal plate and push the bent metal plate. At this time, the bent metal plate will move toward the center plate 12 together with the clamping mechanism 2. After the bent metal plate contacts the support block 316 at the top of the support rod 315, the support rod 315 will rotate first until the bent metal plate contacts the L-shaped lower extension rod 317. At this time, the L-shaped The lower extension rod 317 will be pushed by the bent metal plate to compress the elastic telescopic rod, and at the same time the tension spring will be pulled until the bent metal plate and the push block 313 are pressed against each other, and then the cylinder 311 will continue to be controlled to push the bent metal plate until the bent metal plate and the straight metal plate and the trapezoidal metal plate are pressed against each other. In the process of pushing the bent metal plate, the bent metal plate is protected by the combination of multi-point pushing and elastic blocking force in the opposite direction of pushing, so as to avoid the deformation of the bent metal plate in the process of pushing the bent metal plate and affecting the welding accuracy.

[0047] See Figure 7-Figure 8 The welding mechanism 5 includes support blocks 51 symmetrically fixed to the top of the bottom support plate 1 and located behind the limiting mechanism 4 on the rear side. The tops of the two support blocks 51 are connected to track components 52, and each track component 52 is connected to a track rod 511. The tops of the two track components 52 are connected to square frames 514 through U-shaped frames 513 extending forward. The two square frames 514 are distributed in an eight-shaped shape, and the track rods 511 are also slidably connected in the square frames 514. A welding gun 512 is installed at one end of each track rod 511 close to the center plate 12. The two track rods 511 on the front side and the two track rods 511 on the rear side are respectively connected to a power structure.

[0048] In this embodiment, if Figure 7 and Figure 8 As shown, the power structure includes a horizontal sliding sleeve 515 fixed to the end of the track rod 511 away from the center plate 12, and the left and right horizontal sliding sleeves 515 on each side of the front and rear are both slidably connected to the horizontal rod 516. A vertical slide rail 517 is fixed to the top of the bottom support plate 1 through a connecting block, and the vertical slide rail 517 is connected to the horizontal rod 516 through an electric slider.

[0049] The welding mechanism 5 is used to weld the joint positions of the assembled straight metal plates, trapezoidal metal plates and two bent metal plates. At the same time, the track component 52 is used to limit the moving track of the welding gun 512, so that the welding gun 512 can quickly and accurately weld the joint positions of the straight metal plates, trapezoidal metal plates and two bent metal plates. In addition, this welding method can also ensure that the distance between the welding gun 512 and the joint position is always consistent, thereby ensuring the quality of the weld and making the weld more uniform.

[0050] See Figure 8-Figure 9 The track component 52 includes a U-shaped frame 521 fixed to the top of the support block 51, and the tops of the two vertical sections of the U-shaped frame 521 are hinged with a telescopic plate 522 and an L-shaped connecting plate 523 respectively. The L-shaped connecting plate 523 is inclined, and the bottom of the horizontal section of the L-shaped connecting plate 523 is connected to the telescopic end of the telescopic plate 522. A positioning rod 524 with a positioning hole is fixed to the bottom end of the telescopic plate 522, and a positioning plate 525 is fixed to the top of the vertical section where the U-shaped frame 521 and the telescopic plate 522 are hinged. A plurality of coordination holes 526 are evenly arranged circumferentially on the positioning plate 525, and positioning pins are connected between the positioning holes and the coordination holes 526 at corresponding positions.

[0051] The track component 52 is used to adapt to the degree of inclination of the upper half of the bent metal plate, so as to quickly adjust the welding path of the welding gun 512, and enable the square frame 514 connected to it through the U-shaped frame 513 to also quickly adjust its welding path, thereby ensuring the accuracy of welding. At the same time, it cooperates with the support rod 315 and the support plate 323 to further target bent metal plates with different degrees of inclination, thereby increasing the applicability of the present invention.

[0052] Specifically, after the straight metal plate, the trapezoidal metal plate and the two bent metal plates are assembled, the L-shaped connecting plate 523 and the telescopic plate 522 are rotated first, so that the welding gun 512 at the telescopic plate 522 and the L-shaped connecting plate 523 can be aligned with the joint position of the straight metal plate, the trapezoidal metal plate and the two bent metal plates for precise welding, and then the positioning pins are inserted between the positioning holes and the corresponding matching holes 526, and then the electric slider is controlled to drive the horizontal rod 516 to move from top to bottom, so that The two welding guns 512 are driven by the horizontal sliding sleeve 515 to move along the frame composed of the square frame 514 or the L-shaped connecting plate 523, the U-shaped frame 521 and the telescopic plate 522, so as to weld the joints of the straight metal plate, the trapezoidal metal plate and the two bent metal plates. After the welding is completed, the positioning pins are removed and the L-shaped connecting plate 523 is rotated to a vertical position. Then, the positioning and clamping effect of the clamping mechanism 2 on the bent metal plate is released, and finally the welded barbecue grill body is taken out from above.

[0053] The working steps of the present invention are as follows: In the first step, the operator places the two bent metal plates on the top of the two horizontal frames 221 on the lower left and right sides in turn and is limited by the vertical clamping plate 222. At this time, first ensure that the L-shaped movable plate 21 together with the horizontal slider is located on the side of the horizontal slide rail 11 close to the pushing mechanism 3. At this time, the upper half of the two bent metal plates are in a position close to each other, and then the vertical clamping plate 222 is driven by the synchronous structure to clamp the bent metal plates.

[0054] In the second step, after the bent metal plate is positioned, the operator places the straight metal plate and the trapezoidal metal plate on the rear fixing plate 41 and the front fixing plate 41 respectively, and the limiting plate 411 limits the straight metal plate and the trapezoidal metal plate.

[0055] The third step is that after the straight metal plate and the trapezoidal metal plate are placed, the control cylinder 311 drives the collecting plate 312 to move toward the center plate 12. When the collecting plate 312 moves a certain distance, the supporting plate 323 will first contact the upper plate part of the bent metal plate and push the bent metal plate. At this time, the bent metal plate will move to the left together with the clamping mechanism 2. After the bent metal plate contacts the supporting block 316 at the top of the supporting rod 315, the supporting rod 315 will rotate first until the bent metal plate contacts the L-shaped lower extension rod 317. At this time, the L-shaped lower extension rod 317 will be pushed by the bent metal plate to compress the elastic telescopic rod, and at the same time, the tension spring will be pulled until the bent metal plate is against the push block 313, and then continue to control the cylinder 311 to push the bent metal plate to the left until the bent metal plate and the straight metal plate and the trapezoidal metal plate are pressed against each other.

[0056] In the fourth step, when the control pushing mechanism 3 is used to push the bent metal plate, the pushing block 217 will move toward the straight metal plate and the trapezoidal metal plate and push the pushed block 426. The pushed block 426 will drive the longitudinal sliding sleeve 422 to move toward the square close to the straight metal plate or the trapezoidal metal plate, thereby causing the bending pressure plate 424 to press the straight metal plate or the trapezoidal metal plate, and cooperate with the limit plate 411 to press the straight metal plate or the trapezoidal metal plate to a vertical state. At this time, since the straight metal plate, the trapezoidal metal plate and the two bent metal plates are in a vertical state, the joint positions of the four are precisely fitted.

[0057] The fifth step is to adjust the track component 52 according to the shape of the bent metal plate after the straight metal plate, the trapezoidal metal plate and the two bent metal plates are assembled. Then, the electric slider is controlled to drive the horizontal rod 516 to move from top to bottom, thereby driving the two welding guns 512 along the joint position of the straight metal plate, the trapezoidal metal plate and the two bent metal plates through the horizontal sleeve 515 to move and weld. After the welding is completed, the position of the track component 52 is adjusted, and then the positioning and clamping effect of the clamping mechanism 2 on the bent metal plate is released. Finally, the welded barbecue grill body is taken out from the top.

[0058] Although the embodiments of the present invention have been shown and described above, it will be understood that the above embodiments are illustrative and are not to be construed as limitations on the present invention. A person skilled in the art may make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention, which are still covered by the scope of protection of the present invention.
