[0002] The existing oven inner tank is welded by an inner tank upper ring, an inner tank lower ring and a bottom cover; during welding, the inner tank upper ring and the inner tank lower ring are positioned and fixed by a clamp, and then initially reinforced by a spot welding device, and then fine-processed by a roll welding device.

[0003] The existing roll welding equipment only performs welding processing on the outer side of the inner tank of the oven, which results in gaps on the inner side of the inner tank, making the inner side of the inner tank not smooth and affecting the aesthetics. In order to solve this problem, double roll welding technology is now used to weld the inner side of the inner tank. However, after welding, burrs and unevenness will appear at the inner wall weld. The existing inner tank needs to undergo an enameling process after welding. This process has certain requirements for the smoothness and flatness of the inner tank surface. The above-mentioned problems caused by welding on the inner side will affect the progress of the enameling process. Therefore, it is urgent to solve the problem of burrs and unevenness on the inner weld, which affects the enameling process. Summary of the invention

[0048] Compared with the prior art, the present invention has the following outstanding and beneficial technical effects:

[0049] 1. The present invention uses a fixture to fix and limit the upper and lower circles of the inner tank to ensure the accuracy of the installation position; then the side stop device is pressed against the welds on the outer walls of the upper and lower circles of the inner tank, and the lifting device is used to drive the shaping device to move up and down.

[0052] 3. The side stop portion on the side stop device of the present invention presses against the outer weld, and the shaping wheel presses against the inner weld. During the rolling shaping process, it presses against the side walls of the upper and lower circles of the inner liner, ensuring that the shaping can be performed while ensuring that the upper and lower circles of the inner liner will not be deformed due to the shaping, affecting the overall shape of the upper and lower circles of the inner liner, thereby ensuring the quality of the product.

[0053] 4. The arc-shaped fixing position of the front corner fixing mechanism of the present invention and the arc-shaped design of the outer wall of the rear corner fixing frame cooperate with each other to achieve the fixation of the upper and lower circles of the inner liner at the corners, which can ensure the accuracy of the fixed position and prevent the upper and lower circles of the inner liner from moving during the fixing process, thereby ensuring the smooth progress of subsequent rolling and shaping.

[0054] 5. The driving device provided in the present invention can realize the spacing between two sets of fixtures, so as to meet the fixation of the upper and lower circles of the inner liner of different specifications, so that one device can perform the shaping of the upper and lower circles of the inner liner of various specifications, thereby improving the applicability of the equipment and saving costs.

[0071] The specific implementation modes of the present invention are further described in detail below with reference to the accompanying drawings.

[0072] [Example 1]

[0073] like Figure 1-Figure 3 As shown, a weld shaping machine is used to shape the inner wall welds of the upper and lower rings 6 of the inner tank, thereby ensuring the flatness and smoothness of the inner wall to ensure the smooth progress of the subsequent enameling process.

[0074] It mainly includes a work surface 1, a hole is opened in the middle of the work surface 1, and a fixture 100, a side stop device 200, a shaping device 300 and a lifting device 400 are arranged on the work surface 1;

[0075] The fixture 100 is mainly used to install and position the upper and lower circles 6 of the inner liner; when the upper and lower circles 6 of the inner liner are installed on the device, the side stop device 200 located on the side of the fixture 100 abuts against the outer wall of the weld;

[0076] The lifting device 400 passes through the hole of the work surface 1, and the end is fixed to the lower end surface of the bottom plate 2. The shaping device 300 is installed on the lifting device 400, driving the shaping device 300 to move up and down, so that the shaping device 300 can shape the weld.

[0077] like Figure 4-Figure 5 As shown, the shaping device 300 includes: a lower moving plate 303, a shaping driving member 304, a shaping column 301 and a shaping wheel 302;

[0078] The lower moving plate 303 is installed on the lifting device 400, and the lifting device 400 mainly drives the lower moving plate 303 to move; the middle part of the shaping column 301 is connected to the lower moving plate 303, so that the shaping column 301 can rotate around the connection point, and the shaping wheel 302 is installed on the upper end of the shaping column 301, and the edge of the shaping wheel 302 protrudes from the outer side wall of the shaping column 301, so that the edge of the shaping wheel 302 can abut the weld without being affected by the shaping column 301;

[0079] The shaping drive member 304 is installed on the lower moving plate 303, and its output end is connected to the lower end of the shaping column 301, mainly driving the shaping column 301 to rotate, and providing the shaping wheel 302 with pre-pressure on the upper and lower circles 6 of the inner liner.

[0080] After the upper and lower circles 6 of the inner liner are installed and fixed to the tooling fixture 100, the shaping drive 304 drives the shaping column 301 to rotate, so that the shaping wheel 302 is close to the weld on the inner wall of the upper and lower circles 6 of the inner liner, and first presses against the side stop device 200, and then the lifting device 400 works to drive the shaping device 300 to move upward. Because the shaping wheel 302 is in a pressing state at this time, when it moves to the weld, it rolls and shapes the weld, making it flat and smooth, thereby ensuring the smoothness and flatness of the inner wall of the upper and lower circles 6 of the inner liner.

[0081] The present invention uses a fixture 100 to fix and limit the upper and lower circles 6 of the inner liner to ensure the accuracy of the installation position; then the side stop device 200 presses against the weld on the outer wall of the upper and lower circles 6 of the inner liner, and then drives the shaping device 300 to move up and down through the lifting device 400. During the movement, the shaping wheel 302 rolls on the inner wall weld to shape the weld after inner welding, thereby ensuring the flatness and smoothness of the inner weld, thereby ensuring the normal progress of the subsequent enameling process.

[0082] At the same time, the lower end drives the upper end to abut against each other, so that the shaping pressure can be adjusted, and the shaping driving member 304 is used to provide pressure to achieve the shaping of the weld. When not shaping, the shaping wheel 302 can be moved away from the weld by the shaping driving member 304, which can reduce consumption, avoid unnecessary work, and ensure the service life of the equipment. The shaping driving member 304 can be a cylinder or an oil cylinder.

[0083] In this embodiment, the shaping column 301 is a square tube, and a bearing is installed at the rotation point. The bearing is used to reduce the friction between the shaping column 301 and the rotating shaft during rotation, reduce wear, and ensure the service life.

[0084] The connection between the shaping wheel 302 and the shaping column 301 is similar to the above, so it will not be repeated.

[0085] like Figure 6 As shown, the structure of the side stop device 200 is as follows:

[0086] The side stop device 200 includes a side stop frame 201, at least one side stop driving member 202 and a side stop block 203;

[0087] The side block frame 201 is installed on the side of the fixture 100. A triangular vertical plate is provided on the side block frame 201, so that a triangular support structure is formed on the side block frame 201 to ensure bearing capacity. The side block driving member 202 is installed on the side block frame 201. In this embodiment, two side block driving members 202 are used, which are respectively arranged on the side block frame 201 from top to bottom. The output ends of the side block driving members 202 are respectively connected to the ends of the side block 203 to realize the installation of the side block 203.

[0088] A side stopper 204 is formed on the side stopper 203. The side stopper 204 of the present embodiment is an elongated plane formed by the side protrusion of the side stopper 203. The side stopper 204 can also be designed as an arc-shaped plane according to actual conditions to closely fit the outer wall of the corresponding upper and lower circles 6 of the inner liner.

[0089] The design of the side stop 204 is mainly to reduce the contact area with the upper and lower circles 6 of the inner liner while being able to abut the weld, reduce the impact on the shape of the upper and lower circles 6 of the inner liner, and ensure the overall quality of the upper and lower circles 6 of the inner liner after shaping.

[0090] The side stop driving member 202 drives the side stop block 203 to move, so that the side stop portion 204 abuts against the outer wall of the weld.

[0091] The side stop driving member 202 may be an oil cylinder or a pneumatic cylinder.

[0092] like Figure 7 As shown, the structure of the fixture 100 is as follows:

[0093] The fixture 100 includes a front angle fixing mechanism 101 and a rear angle fixing mechanism 105;

[0094] The front corner fixing mechanism 101 is mainly used to fix the corner 61 of the upper and lower circles 6 of the inner container, and mainly includes a front corner fixing seat 102, a limit driving member 103 and a supporting movable plate 104;

[0095] The front corner fixing mechanism 101 is arranged obliquely relative to the long sides S of the upper and lower circles of the inner container;

[0096] That is, the front corner fixing seat 102 is tilted, and an active cavity is formed in the front corner fixing seat 102, and the supporting active plate 104 is placed in the active cavity. The limiting driving member 103 is installed at the end of the front corner fixing seat 102, and the output end is connected to the supporting active plate 104, and drives the supporting active plate 104 to move in the active cavity. The side wall of one end of the active cavity is arc-shaped, and the end of the supporting active plate 104 is also arc-shaped. The two cooperate to form an arc-shaped fixing position 110, and the curvature of the arc-shaped fixing position 110 is adapted to the curvature of the corner 61 of the upper and lower circles 6 of the inner tank, thereby realizing the clamping and fixation of the corner 61.

[0097] The inclined setting allows the supporting force of the arc end of the movable cavity acting on the corner to offset the supporting force of the supporting movable plate on the corner, while ensuring stable fixation without deforming the upper and lower circles of the inner liner, thereby ensuring the pass rate.

[0098] The rear corner fixing mechanism 105 includes a rear corner fixing frame 106, a pushing member 107 and a pushing block 108;

[0099] The outer side wall of the rear corner fixing frame 106 is configured to be arc-shaped, and the arc of the corner 61 of the upper and lower circles 6 of the inner liner is adapted;

[0100] The push block 108 is installed at the output end of the push member 107. The push member 107 is placed on the side of the rear corner fixing frame 106. The side of the push block 108 is provided with an arc portion 109 for matching the outer wall of the corner 61 of the upper and lower circles 6 of the inner tank.

[0101] During installation, the corners 61 of the upper and lower circles 6 of the inner container are placed in the movable cavity and outside the rear corner fixing frame 106 , that is, the rear corner fixing frame 106 is placed inside the upper and lower circles 6 of the inner container.

[0102] Then, the end of the supporting plate 104 and the side wall of the movable cavity clamp the corner 61 of the upper and lower circles 6 of the inner container; the push block 108 and the rear corner fixing frame 106 clamp the other corner 61, thereby realizing the installation, positioning and fixing of the upper and lower circles 6 of the inner container.

[0103] The arc-shaped fixing position 110 of the front corner fixing mechanism 101 of the present invention and the arc-shaped design of the outer wall of the rear corner fixing frame 106 cooperate with each other to achieve the fixation of the corner 61 of the upper and lower circles 6 of the inner liner, thereby ensuring the accuracy of the fixed position and preventing the upper and lower circles 6 of the inner liner from moving during the fixing process, thereby ensuring the smooth progress of the subsequent rolling and shaping.

[0104] The limiting driving member 103 may be a pneumatic cylinder or an oil cylinder.

[0105] like Figure 8 As shown, the structure of the lifting device 400 is as follows:

[0106] The lifting device 400 includes a fixing frame 401, a lifting driving member 402 and a transmission assembly 403;

[0107] The fixed frame 401 is installed on the lower end surface of the work surface 1, and a guide rail 3 is installed on the fixed frame 401. The lower movable plate 303 is installed on the guide rail 3 through a slider. The guide rail 3 is vertically arranged, and the lower movable plate 303 moves up and down along the guide rail 3;

[0108] The lifting drive member 402 is installed on the fixing frame 401. In this embodiment, it is installed at the lower end of the fixing frame 401. The installation position can be selected by the user.

[0109] The transmission assembly 403 is also installed on the fixing frame 401 , and the lifting drive member 402 is connected to the lower moving plate 303 through the transmission assembly 403 .

[0110] The lifting drive member 402 works to move the lower moving plate 303 up and down on the guide rail 3 through the transmission assembly 403, thereby realizing the up and down movement of the shaping wheel 302 on the weld.

[0111] In this embodiment, the transmission assembly 403 realizes the transmission of power by the cooperation of the screw rod 408 and the screw rod sleeve 407. That is, the screw rod sleeve 407 is installed on the back of the lower moving plate 303, the screw rod 408 is vertically arranged on the fixed frame 401, and the lifting drive member 402 is installed on the back of the fixed frame 401. The connection between the lifting drive member 402 and the screw rod 408 can be realized by the cooperation of the synchronous wheel and the synchronous belt, or the cooperation of the bevel gear to realize the transmission of power.

[0112] The lifting drive member 402 here adopts a servo motor, which can conveniently control the moving distance; other solutions are also possible and are not listed one by one.

[0113] like Figure 8 As shown, in order to control the moving position of the lower movable plate 303, a fixed rod 21 is installed on the side of the fixed frame 401, and at least one sensor 22 is installed on the fixed rod 21. In this embodiment, three sensors are taken as an example. One is set at the upper and lower ends of the fixed rod 21, respectively, and is used for the two extreme moving positions of the lower movable plate 303. The third sensor 22 is installed in the middle of the fixed rod 21 and is used as the origin. In this way, the position of the upper and lower sensors 22 can be adjusted more accurately in the later stage, which is convenient for adjustment during later maintenance or after replacing the upper and lower rings 6 of the inner liner of different specifications, the lifting device 400 can be adjusted.

[0114] Alternatively, the moving position of the lower moving plate 303 can be adjusted more accurately, which can further ensure the accuracy of the adjusted position.

[0115] Alternatively, a sensor 22 may be used, installed at the upper end, to limit the upper limit position.

[0116] like Fig. 9 As shown, in order to further improve the adaptability of the present application, a guide rail 1 is provided on the work surface 1, and two bottom plates 2 are installed on the guide rail 1 through a slider 1, and the bottom plates 2 can move on the guide rail; and each bottom plate 2 is installed with a set of the fixture 100, the side stop device 200, the shaping device 300 and the lifting device 400;

[0117] At least one set of driving device 4 is arranged on the work surface 1, and the driving device 4 drives the two bottom plates 2 to move relative to or toward each other, so that the vertical plates are close to or away from each other, thereby adjusting the distance between the two sets of fixtures 100 and fixing the upper and lower circles 6 of the inner liner of different specifications.

[0118] A guide rail 2 can also be set on the base plate 2, and the guide rail 2 is perpendicular to the guide rail 1. An upper movable plate 3 is installed on the guide rail 2 through a slider, and the rear angle fixing mechanism 105 is installed on the upper movable plate 3; a driving device 2 5 is also installed on each base plate 2, and the driving device 2 5 is used to drive the upper movable plate 3 to move on the guide rail 2, thereby realizing the distance adjustment between the rear angle fixing mechanism 105 and the limit driving member 103.

[0119] like Fig. 9 As shown, in order to constrain the moving position of the bottom plate 2 , a second fixing rod 404 is installed on the work surface 1 , and at least two second sensors 405 are installed on the second fixing rod 404 . The second sensors 405 are respectively installed at the ends of the second fixing rod 404 .

[0120] A second induction sheet 406 is installed on the bottom plate 2. The second induction sheet 406 moves between two second induction sheets 405. The second induction sheets 405 are used to constrain the extreme movement position of the bottom plate 2 to prevent the bottom plate 2 from leaving the guide rail 1.

[0121] Meanwhile, a third sensor 405 is disposed between the two sensors 405. The sensor 405 is used as an origin. The origin can be mainly used as a reference point to facilitate calculation and movement in adjusting the position of the adjusting base plate 2, thereby ensuring the accuracy of the adjustment position.

[0122] The movement of the upper movable plate on the bottom plate is also achieved by the cooperation between the sensor and the sensor sheet. For details, please refer to the above content.

[0123] The structures of the driving device 1 4 and the driving device 2 5 are the same, and the driving device 2 5 is taken as an example for explanation.

[0124] like Fig.10 As shown, the driving device 2 5 includes a screw sleeve 2 51 , a screw 2 52 and a driver 2 53 ;

[0125] The second screw sleeve 51 is installed on the lower end surface of the upper movable plate 3 , and the end of the second screw sleeve 51 is connected to the output end of the second driver 53 , and the second driver 53 is installed on the bottom plate 2 .

[0126] The upper movable plate 3 is driven to move by the second driver 53, so as to adjust the position of the rear corner fixing mechanism 105, and cooperate with the front corner fixing mechanism 101 to achieve the installation and fixation of the upper and lower circles 6 of the inner liner of various specifications.

[0127] The driver 2 53 adopts a servo motor.

[0128] Working principle:

[0129] During operation, the two bottom plates 2 are first moved close to each other, the upper movable plate 3 is moved close to the front corner fixing mechanism 101, and then the upper and lower circles 6 of the inner liner are placed therein, and then the driving device 1 4 drives the two bottom plates 2 to be appropriately separated, and the driving device 2 5 drives the upper movable plate 3 to be appropriately away from the front corner fixing mechanism 101, so that the inner wall of the folded corner 61 of the upper and lower circles 6 of the inner liner is closely attached to the side wall of the rear corner fixing frame 106, and the arc-shaped design makes the fit tighter; the end of the supporting movable plate 104 and the side wall of the movable cavity clamp the folded corner 61 of the upper and lower circles 6 of the inner liner; the push block 108 and the rear corner fixing frame 106 clamp the other folded corner 61, thereby realizing the installation, positioning and fixation of the upper and lower circles 6 of the inner liner, and the design of the two sets of fixtures 100 realizes the fixation and positioning of the four corners of the upper and lower circles 6 of the inner liner;

[0130] Then, the side stop driving member 202 drives the side stop block 203 to move, so that the side stop portion 204 abuts against the outer wall of the weld, thereby completing the fixation of the upper and lower circles 6 of the inner liner.

[0131] Afterwards, the shaping drive 304 drives the shaping column 301 to rotate, so that the shaping wheel 302 is close to the weld on the inner wall of the upper and lower circles 6 of the inner liner, and first presses against the side stop device 200, and then the lifting device 400 works to drive the shaping device 300 to move upward. Because the shaping wheel 302 is in a pressing state at this time, when it moves to the weld, it rolls and shapes the weld. When it is rolled to the uppermost end, it can return for a second rolling, which can make the weld smoother and smoother, and complete the welding shaping of the upper and lower circles 6 of the inner liner.

[0135] [Example 3]

[0136] This embodiment is basically the same as other embodiments, except that the transmission assembly 403 of the lifting device 400 can adopt a gear rack solution, the rack is installed on the lower moving plate 303, the gear is installed at the output end of the lifting drive member 402, and the gear rack is meshed with each other to achieve transmission.

[0137] [Example 4]

[0138] The structure of this embodiment is basically the same as that of the other embodiments, except that the thread formed on the screw in Embodiment 1 is a complete whole with the same rotation direction; whereas the screw of this embodiment can be formed with threads at both ends with opposite rotation directions, and a screw sleeve is sleeved on each thread section, and the screw sleeves are respectively installed on different base plates 2, and the distance between the two base plates 2 can be adjusted by the forward or reverse rotation of the screw.
