[0002] Box beam is one of the most widely used types of house bottom beams. When producing box beams, casting or pressure forming processes are usually adopted. However, with the rise of prefabricated buildings, the pressure forming process is relatively simple and has a small weight and is widely used. Pressure forming is to use mutually cooperating dies and presses to apply pressure to extrude the plate into shape.

[0003] After searching, the Chinese patent publication number CN1009623B discloses a process and equipment for pressure forming of small elongation plates, including placing the peripheral part of the plate on the lower blank clamping piece, which forms a cylindrical body to accommodate the elastic yieldable pad and cooperates with the upper blank clamping piece to clamp the plate, the outer slider descends to flip up the edge of the plate and causes the material in the pad to flow to deform the central part of the plate, so that the deformed area is roughly equal to the area of ​​the finished product, and the moving center slider forms an angular volume and the central part of the plate through the final flow of the supporting material.

[0004] The above patent has the following shortcomings: it uses pressure to extrude the plate into shape, but in this process, sliding friction occurs between the plate and the mold, which causes scratches on the plate or the mold surface, and for the introverted box beam structure (such as Figure 1 ), it cannot be formed in one go, increasing the process cost.

DETAILED DESCRIPTION

[0024] The technical solution of the present invention is further described in detail below in conjunction with specific implementation methods.

[0025] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0026] Embodiment 1: A die production device for producing a bottom beam of a house, such as Figure 1-Figure 8 As shown, it includes a base 1 and a top frame 2 fixed to the top outer wall of the base 1 by bolts, the same set of die assemblies 5 are arranged above the base 1 and below the top frame 2, the top frame 2 is connected to the die assembly 5 through a lifting and pressing mechanism 3, and a unloading mechanism 4 for unloading is arranged at the bottom of the top frame 2.

[0027] The die assembly 5 includes an upper die plate 12 which is transmission-connected to the lifting and pressing mechanism 3 and a lower die plate 10 which is slidingly connected to the base 1 via a slide rod 9. Both sides of the lower die plate 10 are rotationally connected to a bending plate 7, and the other end of the bending plate 7 is rotationally connected to a bending plate 2 13.

[0028] The bottom outer wall of the lower template 10 is buckled with a spring 8, the other end of the spring 8 is buckled with the top outer wall of the base 1, the outer wall of the bending plate 7 is rotatably connected with a connecting rod 6, the other end of the connecting rod 6 is rotatably connected to the base 1, and the side walls of the lower template 10, bending plate 17, and bending plate 2 13 are provided with the same group of linkage components 11.

[0029] The linkage assembly 11 includes shaft one 14, shaft two 16 and shaft three 18, shaft three 18 is fixed to the inner wall of the lower template 10 and is rotatably connected to the inner wall of the bending plate 7, shaft two 16 is rotatably connected to the side wall of the bending plate 7, shaft one 14 is rotatably connected to the inner wall of the bending plate 7 and shaft one 14 is fixed to one end of the bending plate two 13, shaft one 14 and shaft two 16 are matched through a gear set 15, and shaft two 16 and shaft three 18 are matched through a chain transmission assembly 17.

[0030] When the device is in use, in the initial state, the lower template 10, the bending plate 1 7, and the bending plate 2 13 are parallel and coplanar. At this time, the plate is placed on the plane formed by them, and then the upper template 12 is controlled to descend by the lifting and pressing mechanism 3 until the upper template 12 contacts the lower template 10. The upper template 12 continues to descend, thereby causing the lower template 10 to descend, so that the bending plate 1 7 is rotated relative to the lower template 10 through the action of the connecting rod 6, and the plate is bent once. At the same time, when the bending plate 1 7 rotates relative to the lower template 10, the shaft 2 16 also rotates relative to the shaft 3 18, so that the shaft 2 16 rotates under the transmission action of the chain drive assembly 17, and the shaft 2 16 then drives the shaft 14 to rotate through the gear set 15, so that the bending plate 2 13 rotates inward for a second bending until it reaches Figure 4 After the state shown, the bending forming is completed and the sheet is formed into Figure 1 Shape shown.

[0031] The device, by setting the entire die assembly 5 as a combination of a lower template 10, an upper template 12, a bending plate 17, and a bending plate 2 13, utilizes the plane limiting of the lower template 10 and the upper template 12, the rotation of the bending plate 17 relative to the lower template 10, and the rotation of the bending plate 2 13 relative to the bending plate 17 to perform bending type forming. On the one hand, it can realize two inward bending forming in a single movement, saving process steps and improving efficiency. On the other hand, the bending type forming can also prevent scratches caused by friction between the plate and the die assembly 5.

[0032] In addition, on the basis of the bending forming arrangement, the present device arranges a connecting rod 6 and a linkage assembly 11, so that the rotation of the bending plate 1 7 and the rotation of the bending plate 2 13 are coordinated, and the power comes from the descent of the lower template 10, so that the lifting and lowering of the upper template 12, the lifting and lowering of the lower template 10, the rotation of the bending plate 1 7 and the rotation of the bending plate 2 13 are synchronized, which increases the synchronous linkage and reduces the power source layout, which is convenient for volume optimization and cost control.

[0033] In order to solve the lifting and force problems; Figure 5 As shown, the upper template 12 is slidably connected to the bottom of the top frame 2 via a guide rod 19.

[0034] The lifting and pressing mechanism 3 includes a hydraulic cylinder 20 and a connecting block 25, and the connecting block 25 is slidably connected to the bottom of the top frame 2 through a guide rod 21. Both sides of the connecting block 25 are rotatably connected to a connecting rod 23, and the other end of the connecting rod 23 is rotatably connected to a connecting rod 1 22 and a connecting rod 3 24. The other end of the connecting rod 1 22 is rotatably connected to the bottom outer wall of the top frame 2, and the other end of the connecting rod 3 24 is rotatably connected to the top outer wall of the upper template 12.

[0035] When the sheet is in the forming state, the connecting block 25 and the second connecting rod 23 are horizontally parallel, and the first connecting rod 22 and the third connecting rod 24 are vertically parallel.

[0036] When the hydraulic cylinder 20 is extended or retracted, it can drive the connection block 25 to rise or fall, thereby moving the hinge point between the connecting rod 1 22 and the connecting rod 3 24 through the connecting rod 2 23, thereby driving the upper template 12 to rise or fall.

[0037] The device, by setting the lifting and pressing mechanism 3 as a "multi-link" structure composed of connecting rod 1 22, connecting rod 23, and connecting rod 3 24, and when in the sheet forming state, the connecting block 25 and connecting rod 2 23 are horizontally parallel, and the connecting rod 1 22 and connecting rod 3 24 are vertically parallel. Therefore, on the one hand, during the pressure holding stage of the forming state, the entire lifting and pressing mechanism 3 can achieve self-locking, thereby eliminating the need for the hydraulic cylinder 20 to continuously provide pressure. On the other hand, the synchronous rotation of connecting rod 1 22 and connecting rod 3 24 can also double the stroke of the hydraulic cylinder 20 and apply it to the upper template 12, saving stroke. At the same time, during the forming process, when the angle between connecting rod 1 22 and connecting rod 3 24 and the vertical plane approaches 0 degrees, it is also possible to amplify the lateral force provided by connecting rod 23 and apply it to the upper template 12, thereby achieving load amplification.

[0038] In order to solve the problem of cutting materials; Figure 6 As shown, the unloading mechanism 4 is arranged in two groups symmetrically, and each group of the unloading mechanism 4 is composed of a plurality of rubber wheels 28 in a linear array, and the rubber wheels 28 are rotatably connected to a bracket 27 fixed to the outer wall of the bottom of the top frame 2 through a wheel axle 29, and the adjacent wheel axles 29 are driven and matched through a synchronous belt assembly 30, and the outer wall of the bracket 27 is fixed with a hydraulic motor 26 by bolts, and the output shaft of the hydraulic motor 26 is connected to the end of one of the wheel axles 29 through a coupling.

[0039] The formed sheet will be wrapped around the outer wall of the upper template 12 and rise with the upper template 12 until the top bent portion of the sheet contacts the rubber wheel 28 and generates a certain contact pressure. The hydraulic motor 26 will drive the rubber wheel 28 to rotate. Since the friction coefficient between the sheet and the upper template 12 is smaller than the friction coefficient between the sheet and the rubber wheel 28, the rubber wheel 28 drives the sheet to move along the length direction. At this time, the sheet can be transported on the other side by manual labor, a robotic arm or other machinery with a conveying function.

[0040] The device, by providing a feeding mechanism 4, utilizes the rotational energy of a plurality of rubber wheels 28 to ensure reliable feeding of the formed sheet material along the length direction.

[0041] When the present embodiment is in use, in the initial state, the lower template 10, the bending plate 1 7, and the bending plate 2 13 are parallel and coplanar. At this time, the plate is placed on the plane formed by them, and then the upper template 12 is controlled to descend by the lifting and pressing mechanism 3 until the upper template 12 contacts the lower template 10. The upper template 12 continues to descend, thereby causing the lower template 10 to descend, so that the bending plate 1 7 is rotated relative to the lower template 10 through the action of the linkage rod 6, and the plate is bent once. At the same time, when the bending plate 1 7 rotates relative to the lower template 10, the shaft 2 16 also rotates relative to the shaft 3 18, so that the shaft 2 16 rotates under the transmission action of the chain drive assembly 17, and the shaft 2 16 then drives the shaft 14 to rotate through the gear set 15, so that the bending plate 2 13 rotates inward for a second bending until it reaches Figure 4 After the state shown, the bending forming is completed and the sheet is formed into Figure 1 As shown in the shape, when the hydraulic cylinder 20 is extended and retracted during lifting, it can drive the connecting block 25 to lift and lower, thereby moving the hinge point of the connecting rod 1 22 and the connecting rod 3 24 through the connecting rod 2 23, driving the upper template 12 to lift and lower. In addition, the formed sheet will be wrapped around the outer wall of the upper template 12 and rise with the upper template 12 until the top bent part of the sheet contacts the rubber wheel 28 and generates a certain contact pressure. The hydraulic motor 26 will drive the rubber wheel 28 to rotate. Since the friction coefficient between the sheet and the upper template 12 is smaller than the friction coefficient between the sheet and the rubber wheel 28, the rubber wheel 28 drives the sheet to move along the length direction. At this time, the sheet can be transported on the other side by manual labor, a robotic arm or other machinery with a conveying function.

[0042] Embodiment 2: A die production device for producing a bottom beam of a house, such as Figure 7 , 8 As shown, in order to solve the driving problem; this embodiment makes the following improvements on the basis of embodiment 1: the hydraulic cylinder 20 and the hydraulic motor 26 are connected to the same hydraulic system, and the hydraulic system includes an oil tank 32 and a two-way oil pump 33, one end of the two-way oil pump 33 is connected to the oil tank 32, and the other end of the two-way oil pump 33 is connected to the rodless chamber of the hydraulic cylinder 20, and the two-way oil pump 33 and the hydraulic cylinder 20 connecting pipeline are also connected to the hydraulic motor 26 through a one-way pressure valve 31, and the other end of the hydraulic motor 26 is connected to the oil tank 32.

[0043] The one-way pressure valve 31 includes a valve housing 34 and a conical valve body 35. A hollow frame 38 is fixed to the inner wall of the valve housing 34. The conical valve body 35 is slidably connected to the hollow frame 38 through a second sliding rod 37, and a second spring 36 is buckled on the opposite side of the conical valve body 35 and the hollow frame 38.

[0044] When the embodiment is in use, when it is in the descending state, the two-way oil pump 33 is started to deliver the oil in the oil tank 32 to the rodless chamber of the hydraulic cylinder 20, so that the hydraulic cylinder 20 extends. At this time, due to the obstruction of the cone valve body 35 in the one-way pressure valve 31, the pressure of the rodless chamber of the hydraulic cylinder 20 is transmitted to the Figure 8 At the bottom side of the middle conical valve body 35, the conical valve body 35 is tightly fitted with the inner wall of the valve housing 34 to achieve sealing. After molding, the two-way oil pump 33 is started in the reverse direction to gradually extract the oil in the rodless chamber of the hydraulic cylinder 20. At this time, due to the elastic force of the conical valve body 35, the conical valve body 35 will not move due to negative pressure until the plate contacts the rubber wheel 28, and the height of the upper template 12 is also limited. At this time, the two-way oil pump 33 continues to start in the reverse direction, which will gradually increase the negative pressure in the rodless chamber of the hydraulic cylinder 20 and the inner chamber at the bottom of the valve housing 34, so that the conical valve body 35 is attracted by the negative pressure to overcome the elastic force of the spring 2 36 and move. A gap appears between the conical valve body 35 and the valve housing 34, and the oil in the oil tank 32 flows through the hydraulic motor 26 to drive the hydraulic motor 26 to rotate, thereby driving the rubber wheel 28 to rotate for unloading.

[0045] This device, based on the hydraulic drive of the hydraulic cylinder 20 and the hydraulic motor 26, is specifically designed for the pipeline of the hydraulic system and the one-way pressure valve 31. On the one hand, the drive of the hydraulic cylinder 20 and the hydraulic motor 26 is integrated, and the drive source comes from the two-way oil pump 33, which can reduce the power layout. On the other hand, it can also automatically switch the passage of the hydraulic system according to the resistance, without the need for manual control and algorithm intervention, to achieve automation function.

[0046] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
