Description

Technical Field

[0001] This utility model belongs to the field of welding slag bag manufacturing technology, and in particular relates to a welding slag bag body forming device. Background Technology

[0002] The welding slag bale consists of a spherical head, a bale body, trunnions, lugs, and stiffening plates. The bale body weighs approximately 13 tons, is typically 80mm thick, and has a maximum size of 3300mm, classifying it as an ultra-large component. In existing technology, the welding slag bale body is generally formed using a press, resulting in a conical structure. Typically, two fan-shaped bale plates are first pressed into semi-conical plates, which are then welded together to form the conical bale body. However, during the bending process, the fan-shaped bale plates are prone to shifting, affecting the quality of the bale body formation. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a welding slag bale forming device to solve the technical problem in the prior art that the fan-shaped bale is prone to displacement, which affects the bale forming quality.

[0004] To achieve the above objectives, the technical solution adopted by the welding slag bale forming device of this utility model is as follows:

[0005] A welding slag bale forming device, comprising:

[0006] The support platform includes a left support platform and a right support platform that are spaced apart on the left and right sides;

[0007] The first lower roller is rotated between the left and right support platforms;

[0008] The second lower roller is rotatably supported between the left and right support platforms. The first and second lower rollers are arranged parallel to each other and spaced apart. The first and second lower rollers are at the same height.

[0009] The mounting platform is spaced out on the right side of the right support platform;

[0010] The drive structure is mounted on the mounting platform.

[0011] The transmission structure is located between the right support platform and the mounting platform. The transmission structure is connected to the drive structure and is connected to the first lower roller and the second lower roller respectively, so that the first lower roller and the second lower roller are driven to rotate through the transmission structure under the action of the drive structure.

[0012] The upper roller is supported between the left and right support platforms. The upper roller is located above the first and second lower rollers, and the projection of the upper roller axis on the horizontal plane is located at the exact midpoint between the projections of the first and second lower roller axes on the horizontal plane.

[0013] In the vertical direction, a gap is formed between the upper roller and the first and second lower rollers to allow the fan-shaped package plate to pass through;

[0014] The transmission structure includes a transmission rod, which is fixedly connected to the output shaft of the drive structure;

[0015] The braking mechanism is located between the right support platform and the mounting platform. The braking mechanism has a first working state that restricts the rotation of the transmission rod and a second working state that allows the transmission rod to rotate.

[0016] Beneficial effects: This utility model connects the transmission structure and drive structure of the welding slag bale forming device. The transmission structure is connected to the first lower roller and the second lower roller respectively. Under the action of the drive structure, the first lower roller and the second lower roller are driven to rotate through the transmission structure, thereby enabling the movement of the fan-shaped bale plate through the rotation of the first lower roller and the second lower roller. By setting a braking mechanism, the braking mechanism can limit the rotation of the transmission rod, preventing the downward pressure of the upper roller from driving the first lower roller and the second lower roller to rotate when the upper roller presses down on the fan-shaped bale plate. In other words, it prevents the fan-shaped bale plate from shifting, thus ensuring the forming quality of the fan-shaped bale plate.

[0017] Furthermore, the transmission structure includes a transmission gear fixed to the transmission rod, a first gear fixed to the first lower roller, and a second gear fixed to the second lower roller. The transmission gear is located between the first gear and the second gear, and the transmission gear meshes with the first gear and the second gear respectively. A brake gear is also fixed on the transmission rod, and the brake gear is located to the right of the transmission gear.

[0018] Beneficial effects: The transmission structure enables the drive structure to drive the first and second lower rollers to rotate synchronously, and ensures that the first and second lower rollers rotate in the same direction. When braking the first and second lower rollers through the transmission rod, the braking of the first and second lower rollers can be achieved synchronously.

[0019] Furthermore, the braking mechanism includes an upper fixed frame and a lower fixed frame disposed on the upper and lower sides of the brake gear. Both the upper fixed frame and the lower fixed frame are U-shaped. A front brake block and a rear brake block are slidably disposed between the upper fixed frame and the lower fixed frame. The braking mechanism also includes a driving component that drives the front brake block and the rear brake block to move relative to each other in the front-rear direction. The front brake block and the rear brake block are respectively provided with arc-shaped toothed plates that mesh with the brake gear.

[0020] Beneficial effects: The upper and lower fixing frames facilitate the installation of the front and rear brake blocks and guide their sliding.

[0021] Furthermore, the drive assembly includes a hydraulic cylinder fixed to the left side of the mounting platform, a sliding sleeve is slidably provided on the transmission rod, a connecting rod extending in the front-rear direction is fixed to the sliding sleeve, the telescopic end of the hydraulic cylinder is fixedly connected to the connecting rod, and a push rod is hinged between the end of the connecting rod away from the sliding sleeve and the brake block.

[0022] Beneficial effects: The structural design of the drive assembly allows the front and rear brake blocks to move relative to each other in the left and right directions, thereby braking the transmission rod.

[0023] The left support platform includes an upper platform section and a lower platform section that are hinged together. One end of the upper roller is supported on the upper platform section, and one end of the first and second lower rollers is rotatably supported on the lower platform section. A guide rail extending in the vertical direction is fixed on the upper platform section. A pusher is hinged to the lower platform section, and a slider adapted to guide and slide along the guide rail is fixed on the pusher. A side pit is provided on the left side of the left support platform, and a baffle is hinged to the side pit. The side of the baffle facing the left support platform is the free side. A telescopic structure is hinged to the side pit, and the telescopic structure is hinged to the middle of the pusher. A chain connects the upper platform section and the baffle.

[0024] Beneficial effects: When the upper platform section flips downward relative to the lower platform section, it can cause the baffle to flip into the side pit, avoiding interference with the flipping of the upper platform section; when the upper platform section flips upward relative to the lower platform section, it can pull the baffle upward through the chain, so that the baffle covers the top of the side pit, preventing people from falling into the side pit.

[0025] Furthermore, a support column is fixed in the side pit, inclined from left to right and from bottom to top. The left end of the support column is fixed to the bottom of the side pit, and the right end of the support column is fixed to the left side of the lower platform section. The telescopic structure is hinged to the left end of the support column.

[0026] Beneficial effects: The support columns can provide support for the lower platform section in the side pit, ensuring the structural stability of the lower platform section; on the other hand, they can also provide a foundation for the expansion joint.

[0027] Several left limiting blocks are fixed on the right side of the left support platform, and the left limiting blocks are distributed in an arc-shaped interval along the large end side of the fan-shaped package plate.

[0028] Beneficial effect: The setting of the left limit block can facilitate the positioning of the fan-shaped package plate, ensuring that the position of the fan-shaped package plate is more accurate during pressing.

[0029] Furthermore, the side of the left limiting block facing the fan-shaped package plate is an arc-shaped surface adapted to the fan-shaped package plate.

[0030] Beneficial effect: The curved surface allows the fan-shaped package plate to fit more closely with the left limiting block.

[0031] A left laser emitter is fixed to the left side of the left support platform, and a right laser emitter is fixed to the right side of the right support platform. The large end face of the fan-shaped package plate is provided with a left bisector for cooperating with the left laser emitter, and the small end face of the fan-shaped package plate is provided with a right bisector for cooperating with the right laser emitter. The number of left bisectors and right bisectors is equal.

[0032] Beneficial effects: The laser emitter and the bisectors can further determine the pressing position of the sector-shaped package plate each time, ensuring the pressing accuracy of the sector-shaped package plate. Attached Figure Description

Detailed Implementation

[0040] The following is a detailed description of a welding slag bale forming device according to the present invention, with reference to the accompanying drawings and specific embodiments:

[0041] The welding slag bale has a conical structure. When welding the slag bale, two fan-shaped bale plates are pressed into a semi-conical plate, and then the two semi-conical plates are welded together to form a conical bale; the bale thickness is 80mm.

[0042] like Figure 1-6 As shown, the welding slag bale forming device of this utility model includes a support platform, which includes a left support platform 22 and a right support platform 3 spaced apart from each other. An mounting platform 4 is spaced apart on the right side of the right support platform 3. A first lower roller 1 and a second lower roller 2 are rotatably arranged between the left support platform 22 and the right support platform 3. The first lower roller 1 and the second lower roller 2 are arranged parallel to each other and spaced apart from each other. The first lower roller 1 and the second lower roller 2 have the same height, and the diameter of the first lower roller 1 is equal to the diameter of the second lower roller 2. An upper roller 21 is also supported between the left support platform 22 and the right support platform 3. The upper roller 21 is located above the first lower roller 1 and the second lower roller 2, and the projection of the axis of the upper roller 21 onto the horizontal plane is located at the exact midpoint between the projections of the axes of the first lower roller 1 and the second lower roller 2 onto the horizontal plane. In the vertical direction, a gap is formed between the upper roller 21 and the first lower roller 1 and the second lower roller 2 for the fan-shaped package plate 33 to pass through. That is, the fan-shaped package plate 33 passes through the gap between the upper roller 21 and the first lower roller 1 and the second lower roller 2, and the upper roller applies a downward force to the fan-shaped package plate 33, pressing the fan-shaped package plate 33 downward between the first lower roller 1 and the second lower roller 2. In this embodiment, the principle and structure of the upper roller 21 applying a downward force to the fan-shaped package plate are prior art and will not be described in detail here. For example, the application of a downward force by the upper roller 21 can be found in the patent with authorization announcement number CN217289930U, where a first hydraulic rod and a second hydraulic rod are set at both ends of the upper roller. During operation, the first hydraulic rod and the second hydraulic rod can be controlled to move the upper roller up or down, adjusting the downward pressing force of the upper roller.

[0043] The mounting platform 4 is provided with a drive structure. In this embodiment, the drive structure is a drive motor 17 fixed on the mounting platform 4. A transmission structure is provided between the right support platform 3 and the mounting platform 4. The transmission structure is connected to the drive motor 17 and is connected to the first lower roller 1 and the second lower roller 2 respectively, so that the first lower roller 1 and the second lower roller 2 are driven to rotate through the transmission structure under the action of the drive structure.

[0044] In this embodiment, the transmission structure includes a transmission rod 5, which is fixedly connected to the output shaft of the drive motor 17. The end of the transmission rod 5 away from the drive motor 17 is rotatably mounted on the right support platform 3. The transmission structure includes a transmission gear 6 fixed to the transmission rod, a first gear 7 fixed to the first lower roller 1, and a second gear 8 fixed to the second lower roller 2. The transmission gear 6 is located between the first gear 7 and the second gear 8, and the transmission gear 6 meshes with the first gear 7 and the second gear 8 respectively. When the drive motor 17 operates, it drives the transmission rod 5 to rotate, and the transmission rod 5 drives the transmission gear 6 to rotate. The transmission gear 6 meshes with the first gear 7 and the second gear 8 respectively, so that the transmission rod 5 drives the first lower roller 1 and the second lower roller 2 to rotate synchronously.

[0045] A braking mechanism is provided between the right support platform 3 and the mounting platform 4. The braking mechanism includes a first working state that restricts the rotation of the transmission rod 5 and a second working state that allows the transmission rod 5 to rotate. A brake gear 9 is also fixed on the transmission rod, and the brake gear 9 is located to the right of the transmission gear 6.

[0046] The braking mechanism includes an upper fixed frame 18 and a lower fixed frame 10 disposed on the upper and lower sides of the brake gear 9. Both the upper fixed frame 18 and the lower fixed frame 10 are U-shaped. A front brake block 11 and a rear brake block 12 are slidably disposed between the upper fixed frame 18 and the lower fixed frame 10. The front brake block 11 and the rear brake block 12 are respectively provided with arc-shaped toothed plates that mesh with the brake gear 9. In this embodiment, a front guide rod 20 and a rear guide rod 19 are slidably disposed between the upper fixed frame 18 and the lower fixed frame 10. The front brake block 11 is fixed on the front guide rod 20, and the rear brake block 12 is fixed on the rear guide rod 19. In this embodiment, the front brake block 11 and the rear brake block 12 move relative to each other in the left and right directions to engage and brake the brake gear 9 on the left and right sides of the brake gear 9.

[0047] The braking mechanism also includes a drive assembly for driving the front brake block 11 and the rear brake block 12 to move relative to each other in the front-rear direction; the drive assembly includes a hydraulic cylinder 13 fixed on the left side of the mounting platform 4, the hydraulic cylinder 13 is telescopic in the left-right direction, a sliding sleeve 14 is slidably provided on the transmission rod 5, and connecting rods 15 extending in the front-rear direction are fixed on the front and rear sides of the sliding sleeve 14 respectively, the telescopic end of the hydraulic cylinder 13 is fixedly connected to the connecting rod 15, and a push rod 16 is hinged to the middle of the brake block at the end of the connecting rod 15 away from the sliding sleeve 14. In this embodiment, there are two push rods 16, one of which is hinged to the middle of the front guide rod and the other push rod is hinged to the middle of the rear guide rod. The hydraulic cylinder 13 extends, pushing the connecting rod 15 on the sliding sleeve 14 to move along the extension direction of the transmission rod 5, thereby driving the push rod 16 to push the front brake block 11 and the rear brake block 12 toward the brake gear 9. The arc-shaped toothed plate meshes with the brake gear 9, thereby restricting the rotation of the brake gear 9. At the same time, it also restricts the rotation of the transmission rod 5, thus braking the first lower roller 1 and the second lower roller 2. When the upper roller 21 presses down on the fan-shaped package plate 33, it prevents the downward pressure of the upper roller 21 from driving the first lower roller 1 and the second lower roller 2 to rotate, that is, it prevents the fan-shaped package plate 33 from shifting, thus ensuring the forming quality of the fan-shaped package plate 33.

[0048] The left support platform 22 includes an upper platform section 23 and a lower platform section 24 that are hinged together. One end of the upper roller 21 is supported on the upper platform section 23, and one end of the first lower roller 1 and the second lower roller 2 are rotatably supported on the lower platform section 24. A guide rail 25 extending in the vertical direction is fixed on the upper platform section 23. A pusher 26 is hinged to the lower platform section 24, and a slider 27 that is fixedly installed on the pusher 26 and adapted to guide the sliding of the guide rail 25 is sliding. A side pit 31 is provided on the left side of the left support platform 22, and a baffle 29 is hinged to the side pit 31. The side of the baffle 29 facing the left support platform 22 is the free side. A telescopic structure is hinged to the side pit 31, and the telescopic structure is hinged to the middle of the pusher 26. The hinge point between the pusher 26 and the lower platform section 24, the slider 27 on the pusher 26, and the hinge point between the pusher 26 and the telescopic structure form a triangle. A chain 28 connects the upper platform section 23 and the baffle 29. In this embodiment, the telescopic structure is a hydraulic rod 30; when the hydraulic rod 30 extends, it pushes the pusher 26 to rotate around the hinge point between the pusher 26 and the lower platform section 24. The slider 27 on the pusher 26 pushes the upper platform section 23, so that the upper platform section 23 is directly above the lower platform section 24. At this time, the slider 27 of the pusher 26 is located at the lower end of the guide rail 25. The upper platform section 23 pulls the baffle 29 upward via the chain 28 to cover the top of the side pit 31; the hydraulic rod 30 The hydraulic rod 30 retracts, causing the pusher 26 to rotate around the hinge point between the pusher 26 and the lower platform section 24. The slider 27 on the pusher 26 pulls the upper platform section 23 downwards, causing it to gradually tilt into the side pit 31. At this time, the slider 27 of the pusher 26 moves along the guide rail 25 to the upper end of the guide rail 25. Simultaneously, as the upper platform section 23 rotates downwards, the baffle 29 also flips into the side pit 31, preventing interference with the flipping of the upper platform section 23. The opening and closing mechanism of the baffle 29 in this invention also avoids the low work efficiency caused by manually opening and closing the baffle 29, and the risks of squeezing hands and feet and falling into the pit during the opening or closing process, resulting in a low safety factor.

[0049] A support column 32, inclined from left to right and from bottom to top, is fixed in the side pit 31. The left end of the support column 32 is fixed to the bottom of the side pit 31, and the right end of the support column 32 is fixed to the left side of the lower platform section 24, so that the support column 32 provides support for the lower platform section 24 in the side pit 31, ensuring the structural stability of the lower platform section 24. The telescopic structure is hinged to the left end of the support column 32, that is, the support column 32 forms the installation foundation for the telescopic structure.

[0050] Several left limiting blocks 34 are fixed on the right side of the left support platform 22. The left limiting blocks 34 are distributed in an arc-shaped interval along the large end side of the fan-shaped package plate 33. Thus, when the fan-shaped package plate 33 is moved, the left limiting blocks 34 limit the large end side of the fan-shaped package plate 33. Before pressing the fan-shaped package plate 33, it is convenient to position the fan-shaped package plate 33. Moreover, it can make the fan-shaped package plate 33 advance in an arc along the left limiting blocks 34 when feeding, instead of feeding vertically with the rotation of the first lower roller 1 and the second lower roller 2. This saves the manpower and time of the operator to adjust the feeding direction of the fan-shaped package plate 33 with a pry bar. The side of the left limiting block 34 facing the fan-shaped package plate 33 is an arc-shaped surface that fits the fan-shaped package plate 33, so that the left limiting block 34 can fit the fan-shaped package plate 33 more closely.

[0051] A left laser emitter 35 is fixed to the left side of the left support platform 22, and a right laser emitter 36 is fixed to the right side of the right support platform 3. The large end face of the fan-shaped package plate 33 is provided with a left bisector for cooperating with the left laser emitter 35, and the small end face of the fan-shaped package plate 33 is provided with a right bisector for cooperating with the right laser emitter 36. The number of left and right bisectors is equal. The laser emitter emits a laser, and when the fan-shaped package plate 33 is moved, the left bisector of the fan-shaped package plate 33 is aligned with the laser emitted by the left laser emitter 35, and the right bisector 37 of the fan-shaped package plate 33 is aligned with the laser emitted by the right laser emitter 36. At this time, the bisector 37 is located directly below the axis of the upper roller 21, that is, the fan-shaped package plate 33 is pressed at the bisector 37. In this embodiment, the fan-shaped package plate 33 is pressed by 32 bisectors 37.

The front brake block and the rear brake block are respectively provided with arc-shaped toothed plates that mesh with the brake gear. In other embodiments, the braking mechanism may also include a front fixed frame and a rear fixed frame disposed on the front and rear sides of the brake gear.
