Description

Technical Field

[0001] The present invention relates to the technical field of steel pipe bending, and specifically to a stamping and forming device for steel pipes of ton barrels. Background Art

[0002] In the production and manufacturing process of ton barrels, as an important structural component, the forming quality of steel pipes directly affects the overall performance and service life of ton barrels. To meet the structural design requirements of ton barrels, it is often necessary to bend straight steel pipes into quadrilaterals, and stamping and bending treatment is the key process to achieve this goal.

[0003] Currently, the traditional stamping and bending forming method for steel pipes mainly adopts a single-piece and single-pipe processing mode, that is, only one steel pipe can be processed by stamping and bending each time. In the specific operation process, to form the four bent parts of the quadrilateral steel pipe, the operator needs to hold the steel pipe and continuously adjust the state of the steel pipe according to the progress of stamping and bending. This process inevitably involves multiple adjustments, increasing the processing time and reducing the production efficiency. The single operation takes about 8 - 10 minutes, and the daily production capacity is less than 200 pieces. Taking a medium-sized enterprise with an annual output of 100,000 ton barrels as an example, only for the steel pipe forming link, 8 - 10 sets of equipment and 15 - 20 workers need to be configured, resulting in a discrete and inefficient production process. According to industry research data, the production efficiency of this mode is 60% - 70% lower than that of an automated production line, and it cannot meet the production volume requirements of modern large-scale production, seriously restricting the production efficiency of ton barrels. During the peak order period, the product delivery cycle is usually extended by 20 - 30 days, directly affecting customer satisfaction and the competitiveness of the enterprise in the market.

[0004] At the same time, due to the low production efficiency, workers need to continuously repeat 200 - 300 monotonous operations such as clamping, stamping, and taking parts every day in a workshop environment with a noise level as high as 85 decibels, with extremely high labor intensity. Long-term repetitive labor not only easily leads to occupational diseases such as lumbar muscle strain and tenosynovitis of workers, but also increases the potential risk of work-related accidents due to distraction of attention. According to statistics, the incidence rate of mechanical injury accidents in traditional processing workshops is 3 - 5 times higher than that in automated workshops, seriously threatening the occupational health and safety of front-line employees.

[0005] Therefore, it is urgent to develop a new stamping and bending forming technology or device for steel pipes of ton barrels to solve the many problems existing in the above traditional methods and meet the requirements of high-efficiency and high-quality production of ton barrel steel pipes.

[0035] In the present invention, unless otherwise clearly defined and limited, terms such as "installation", "connection", "connection", "fixation" and other terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0036] The following will be further described in conjunction with the drawings and specific embodiments:

[0037] In order to reduce the degree of manual participation during the stamping and bending process of steel pipes and change the current situation where only one steel pipe can be bent at a time, this embodiment provides a new stamping and forming device that can bend multiple steel pipes simultaneously.

[0038] As Figures 1-3As shown in the figure, the device includes a first stamping component 1 and a second stamping component 2 which are distributed front and back and offset left and right. A first transfer component 3 and a second transfer component 4 are arranged vertically between them, and the first transfer component 3 and the second transfer component 4 are perpendicular to each other. In addition, a supporting and transferring mechanism 5 is arranged on the side of the first stamping component 1 away from the transfer component. When using this device to bend multiple steel pipes, first, the multiple steel pipes are distributed in parallel on the supporting and transferring mechanism 5, and the steel pipes are conveyed to the first stamping component 1. Then, the first stamping component 1 bends the steel pipes by stamping, deforming the multiple steel pipes into a right-angle structure. After the first transfer component 3 clamps the multiple steel pipes in a right-angle shape, it transfers the multiple steel pipes to the second transfer component 4 and places the multiple steel pipes on the second transfer component 4. When the second transfer component 4 works, it conveys the multiple steel pipes to the second stamping component 2. First, the second stamping component 2 performs stamping and bending on two sides of the right-angle steel pipe, making the ends of the two sides move closer to each other and then performing stamping and bending on them. As can be seen from the above, this device performs stamping and bending on multiple steel pipes simultaneously, thereby forming the frame outer frame components of the ton barrel, improving the efficiency of steel pipe bending processing. In addition, during this processing process, the degree of manual participation is reduced, avoiding the fatigue of the staff.

[0039] As Figure 7 shown, in order to realize the preliminary bending treatment of the steel pipe, the first stamping component 1 includes a bracket 12, a lower stamping die 15, an upper stamping die 13, a first telescopic cylinder 11, etc. The first telescopic cylinder 11 is installed upside down on the top of the bracket 12, and the telescopic end of the first telescopic cylinder 11 penetrates through the top of the bracket 12 and is connected to the upper stamping die 13, so as to control the lifting of the upper stamping die 13 relative to the bracket 12. In addition, the lower stamping die 15 is fixedly installed at the bottom of the bracket 12, and a plurality of matching concave arc grooves are respectively arranged on the side walls of the upper stamping die 13 and the lower stamping die 15 close to each other. That is, when the upper stamping die 13 and the lower stamping die 15 are attached, a plurality of stamping and bending spaces are formed, forcing the multiple steel pipes placed on the lower stamping die 15 to be deformed.

[0040] As Figure 7 shown, in order to place the steel pipe more stably on the lower stamping die 15 before stamping and bending the steel pipe, a row of supporting wheels 14 is arranged on both sides of the bracket 12. The number of each row of supporting wheels 14 is equal to the number of stamping and bending spaces, and the multiple supporting wheels 14 are directly opposite to the multiple stamping and bending spaces one by one. At the same time, the tangent of the supporting wheel 14 is parallel to the tangent of the outer surface of the stamping and bending space. In addition, an annular curved surface groove adapted to the steel pipe is arranged on the curved surface of the supporting wheel 14, so that the steel pipe can be placed on the supporting wheel 14, and the position of the steel pipe is restricted by the structural characteristics of the supporting wheel 14.

[0041] In order to be able to achieve the folding and bending of steel pipes, the position of the steel pipe relative to the first stamping assembly 1 can be adjusted by on-site measurement. Or a plate body can be supported by a frame on the side of the first stamping assembly 1 away from the transfer mechanism 5. This plate body plays a role of resistance, and when the end of the steel pipe contacts the plate body, the middle part of the steel pipe can be made to face the first stamping assembly 1 directly.

[0042] As Figures 1-3 shown, in order to be able to support multiple steel pipes and convey the steel pipes to the first stamping assembly 1, the transfer mechanism 5 includes a chassis and a row of supporting wheels 14 installed on the chassis. Each row of supporting wheels 14 is sleeved on the same shaft body, and the shaft body is connected to the chassis through a bearing seat at the end. In addition, the end of a certain shaft body can be connected to the power output shaft of the motor, which can facilitate the control of the movement of the steel pipe while stably supporting the steel pipe. In addition, the supporting wheels 14 of the transfer mechanism 5 and the first stamping assembly 1 are distributed in one-to-one correspondence on the same straight line.

[0043] As Figures 4-6 shown, in order to be able to bend the steel pipe again, the second stamping assembly 2 includes a central member 21, a first stamping mechanism 22, a second stamping mechanism 23, and a third stamping mechanism 24 distributed outside the central member 21. The first stamping mechanism 22, the second stamping mechanism 23, and the third stamping mechanism 24 are respectively located at three corners of a quadrilateral. During work, the second stamping mechanism 23 and the third stamping mechanism 24 work first to achieve the bending of two sides of the right-angled steel pipe, and then the first stamping mechanism 22 stamps and processes the ends adjacent to the two sides again, thereby bending the steel pipe to form a quadrilateral structure.

[0044] As Figure 5 、 Figure 6 shown, specifically, the central member 21 includes a connecting frame 211 and three first stamping dies 212 respectively installed on the connecting frame 211. At one end where the first stamping mechanism 22, the second stamping mechanism 23, and the third stamping mechanism 24 are close to each other, a second stamping die 231 is provided. The second stamping die 231 can be controlled by a telescopic cylinder to fit the first stamping die 212, and the first arc-shaped grooves 213 and the second arc-shaped grooves on the side walls of the first stamping die 212 and the second stamping die 231 form a plurality of stamping and bending spaces. When the second transfer component 4 controls multiple steel pipes with a right-angled structure to move to the second stamping assembly 2, two sides of multiple steel pipes respectively contact the two first stamping dies 212 on the lower side, and then the corresponding second stamping die 231 is controlled by the telescopic cylinder to move and fit the first stamping die 212, so as to achieve the bending of the two sides. After the two sides are bent, their free ends are arranged to fit the first stamping die 212 on the upper side, and finally the corresponding second stamping die 231 is controlled by the telescopic cylinder to move and fit the first stamping die 212, realizing the bending and closing process of the steel pipe. The steel pipe bent into a quadrilateral structure can be taken off by the staff.

[0045] As Figure 6 shown, in order to facilitate the bending of the two sides of the right-angled steel pipe, a row of pressing wheels 232 are respectively provided on the second stamping mechanism 23 and the third stamping mechanism 24. The pressing wheels 232 are directly opposite to the stamping and bending spaces one by one, and the two rows of pressing wheels 232 are both arranged on the sides of the second stamping mechanism 23 and the third stamping mechanism 24 close to the first stamping mechanism 22. The pressing wheels 232 and the supporting wheels 14 have the same model.

[0046] The above-mentioned second stamping die 231 is installed in the same way as the lower stamping die 15 and the upper stamping die 13, that is, each second stamping die 231 is installed on a frame body similar to the bracket 12, and then, a plurality of brackets 12 are installed on the frame of the device, and by using the structural characteristics of the brackets 12, the stamping die can be stably supported and placed. In addition, the connecting frame 211 is installed on the frame of the device to stably support the installation of the first stamping die 212.

[0047] As Figure 11 shown, in order to separate the right-angled steel pipe from the first stamping assembly 1, the first transfer assembly 3 includes a support frame 31, a clamping mechanism 32, etc. The clamping mechanism 32 is movably installed on the support frame 31, and the support frame 31 is fixedly installed on the bracket 12 of the first stamping assembly 1. In addition, under the action of the support frame 31, the movement of the clamping mechanism 32 can be controlled, and thus the transfer process can be realized after the clamping mechanism 32 clamps the right-angled steel pipe.

[0048] As Figure 12 shown, specifically, the support frame 31 includes a U-shaped frame 313 and two parallel support rails 311. A sleeve plate 314 is fixedly arranged at the bottom of the U-shaped frame 313, and the two support rails 311 penetrate through the two sleeve plates 314. The end faces of the sleeve plate 314 and the support rails 311 are both set as convex structures, so that the U-shaped frame 313 can be stably and movably installed on the support rails 311. In addition, the end of the support rail 311 is connected to the bracket 12 of the first stamping assembly 1. A first chain 312 is connected to the side of each support rail 311 through a sprocket and a bearing seat. The central shaft of a certain sprocket is connected to the power output shaft of a motor such as a servo motor or a stepping motor. A clamping post 316 is fixedly arranged on the first chain 312. The T-shaped end of the clamping post 316 is inserted into the T-shaped card slot 315 of the sleeve plate 314 to realize the connection between the first chain 312 and the U-shaped frame 313, so that the U-shaped frame 313 can be controlled to move back and forth along the length direction of the support rail 311 when the motor controls the rotation of the first chain 312.

[0049] As Figure 13As shown, the clamping mechanism 32 includes a second telescopic cylinder 321, a lifting frame 323, a clamping plate 327, a flipping plate 326, etc. The second telescopic cylinder 321 is installed upside down on the C-shaped frame 313. The lifting frame 323 is located inside the C-shaped frame 313 and is connected to the telescopic end of the second telescopic cylinder 321. The guide plate 322 fixed above the lifting frame 323 penetrates through the C-shaped frame 313. When the lifting frame 323 is stably installed, the height of the lifting frame 323 can be adjusted under the action of the second telescopic cylinder 321. The clamping plate 327 is hinged below the lifting frame 323, and a fourth telescopic cylinder 328 is hinged between the clamping plate 327 and the lifting frame 323. That is, the rotation of the clamping plate 327 around the axis can be controlled by the operation of the fourth telescopic cylinder 328 to adapt to the inclined side of the right-angled steel pipe. The flipping plate 326 is arranged parallel to the clamping plate 327 and is hinged to the end of the clamping plate 327. At the same time, a driving plate 324 installed at the end of the flipping plate 326 is hinged to the clamping plate 327 with a third telescopic cylinder 325. When the third telescopic cylinder 325 expands and contracts, the flipping plate 326 can be forced to rotate around the axis. After the steel pipe is bent into a right-angled shape and one of its sides contacts the clamping plate 327, the flipping plate 326 rotates to cooperate with the clamping plate 327 to firmly clamp the sides of multiple right-angled steel pipes. Furthermore, when the C-shaped frame 313 moves, the steel pipes can be transferred to the second transfer component 4.

[0050] As Figure 8 shown, in order to enable multiple steel pipes placed at the second transfer component 4 to move stably to the second stamping component 2, the second transfer component 4 includes a guiding device 41 and a moving device 42. The moving device 42 is arranged above the guiding device 41.

[0051] As Figure 9 shown, specifically, the guiding device 41 includes a supporting rail 411 and a second chain 412. The supporting rail 411 is set as a frame structure. The sprockets at both ends inside the second chain 412 are connected and installed on the inside of the supporting rail 411 through bearing seats. A connecting plate 414 is fixedly arranged on the second chain 412. At the same time, one of the sprockets is connected to the motor.

[0052] As Figure 10As shown in the figure, the mobile device 42 includes a bottom frame 421, a supporting frame 423 and two rows of wheel bodies 425. The supporting frame 423 is fixedly installed in the middle of the bottom frame 421, and a plurality of limiting arc grooves 424 are provided on the supporting frame 423. The two rows of wheel bodies 425 are distributed on both sides of the bottom frame 421, and the wheel bodies 425 are aligned with the limiting arc grooves 424 one by one. The depth of the limiting arc groove 424 is greater than the diameter of the steel pipe, and the bottom of the limiting arc groove 424 is adapted to the bent part of the steel pipe. Therefore, when the right-angled steel pipe moves to the bottom frame 421, the bent part of the right-angled steel pipe can be inserted into the limiting arc groove 424, and the right-angled steel pipe can be stably placed by using the structural characteristics of the supporting frame 423 and the cooperation of the wheel bodies 435. Even a rubber layer can be provided on the side wall of the limiting arc groove 424 to increase the difficulty of the steel pipe movement.

[0053] As Figure 9 , Figure 10 shown in the figure, a buckle post 422 is fixedly arranged at the bottom of the bottom frame 421, and a buckle groove 413 is arranged on the upper side surface of the supporting rail 411. The buckle post 422 is installed in the buckle groove 413 to realize the movable and stable connection between the bottom frame 421 and the supporting rail 411. And the connecting plate 414 is connected to the bottom frame 421, so that the bottom frame 421 can be controlled to reciprocate under the condition of the chain rotation, and the transfer of a batch of steel pipes can be realized.

[0054] The above is only the preferred embodiment of the present invention and is not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
