Description

Technical Field

[0001] The invention relates to the technical field of cold bending processing, and in particular to a cold bending forming machine for producing toilet frame parts. Background Art

[0002] The toilet frame is a functional frame installed on the toilet to assist in the use of the toilet. It mainly plays a stable supporting role. It can not only provide additional support for users and optimize the sitting experience, but also provide a stable grip and support point for people with limited mobility during the process of sitting up, thereby improving the safety and convenience of toilet use. In order to ensure firmness, the toilet frame is generally made of metals such as stainless steel and aluminum alloy. At the same time, in order to ensure the material performance and meet the shape design requirements of the components, the components of the toilet frame need to be shaped by cold bending forming equipment.

[0003] A cold roll forming machine is a metal processing equipment that applies external force to metal materials at room temperature to deform the metal to form profiles or components with specific shapes. A traditional cold roll forming machine is mainly composed of a drive mechanism, two lower pressure rollers and an upper pressure roller with adjustable height. The three pressure rollers form a finished product in the shape of a Chinese character. The steel bar is inserted between the three pressure rollers. The three pressure rollers convey the flat steel by rotating and squeeze the flat steel during the conveying process to achieve the bending of the steel bar. Among them, adjusting the height of the upper pressure roller can change the bending degree of the steel bar.

[0004] The horseshoe-shaped support ring on the toilet frame is made of bent flat steel. The curvature at different positions on the support ring is different. When using a cold bending machine to bend the flat steel, the height of the upper pressure roller needs to be continuously adjusted. When the upper pressure roller rises to reduce the curvature of the flat steel, the pressure on the flat steel from the pressure roller is reduced. At this time, the friction between the pressure roller and the flat steel is reduced, resulting in slippage between the three pressure rollers during flat steel processing, which in turn affects the bending accuracy and processing efficiency of the flat steel. Summary of the invention

[0005] The purpose of the present invention is to propose a cold bending forming machine for the production of toilet frame parts in order to solve the problem that when the upper pressure roller is raised to reduce the curvature of the flat steel, the pressure on the flat steel from the pressure roller is reduced, and the friction between the pressure roller and the flat steel is reduced, causing the flat steel to slip between the three pressure rollers during processing.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technology: a cold roll forming machine for producing toilet frame parts: comprising a driving body, a hydraulic rod is fixedly installed on the top of the driving body, the telescopic end of the hydraulic rod is fixedly connected to a lifting platform sliding inside the driving body, a motor is fixedly installed inside the driving body and on the lifting platform, a lower pressure roller and an upper pressure roller are arranged on the outside of the driving body, and also includes: A support mechanism, the support mechanism comprising a clamping block rotatably connected to the interior of the upper pressure roller, a push plate slidably connected to the interior of the upper pressure roller, a pushing assembly disposed inside the upper pressure roller, and a transmission unit disposed on one side of the pushing assembly; When the hydraulic rod drives the upper pressure roller to rise and reduce the bending angle of the flat steel, the push plate pushes the clamp block to deflect, so that the clamp block supports and clamps the inner side of the flat steel; when the hydraulic rod drives the upper pressure roller to descend and increase the bending angle of the flat steel, the push plate pushes the clamp block to deflect in the opposite direction, so that the clamp block applies pressure to the outer wall of the flat steel.

[0007] As a further description of the above technical solution: the pushing assembly includes a threaded column rotatably connected to the inside of the upper pressure roller, the external thread of the threaded column is connected to a connecting frame rotatably connected to the push plate, the internal sliding connection of the connecting frame is connected to a positioning rod, the positioning rod limits the rotation of the connecting frame, and the rotation of the threaded column drives the connecting frame to move horizontally.

[0008] As a further description of the above technical solution: the transmission unit includes a gear fixed to the outer end of the threaded column, and one side of the gear is meshingly connected with a toothed plate.

[0009] As a further description of the above technical solution: it also includes a straightening component, which includes a sleeve slidably connected to the outside of the lower pressure roller and the upper pressure roller and fixed to the motor drive shaft, and a groove for constraining the flat steel is formed between the lower pressure roller or the upper pressure roller and the sleeve.

[0010] As a further description of the above technical solution: one side of the driving body is fixedly connected to a front frame plate fixed to the tooth plate, one side of the lower pressure roller is rotatably connected to a connecting plate, an electric telescopic rod with a telescopic end fixed to the connecting plate is fixedly installed on the front frame plate, and also includes an adjustment component for adjusting the position of the upper pressure roller.

[0011] As a further description of the above technical solution: it also includes a protection mechanism, which includes a mounting frame slidably connected to the inside of the upper pressure roller, a baffle is fixedly connected to the mounting frame, and one end of the threaded column is fixedly connected to a spiral groove rod passing through the mounting frame.

[0012] As a further description of the above technical solution: a connecting unit is arranged on the outside of the spiral groove rod, and the connecting unit includes a ring which is slidably connected to the inside of the upper pressure roller and sleeved on the outside of the spiral groove rod, and the inner wall of the ring is provided with a protrusion which is embedded in the spiral groove of the spiral groove rod. The spiral groove rod rotates to drive the ring to slide inside the upper pressure roller through the protrusion, and a spring is fixedly connected between the ring and the mounting frame.

[0013] As a further description of the above technical solution: the adjustment component includes a slider slidably connected to the inside of the front frame plate and fixed to the positioning rod, the inside of the slider is slidably connected to a square rod, the outer end of the square rod is fixedly connected to a fixed frame rotatably connected to the upper pressure roller, and the internal thread of the slider is connected to a screw rod rotatably connected to the square rod.

[0014] In summary, due to the use of the above-mentioned technology, a cold roll forming machine for producing toilet frame parts has the following beneficial effects: In the present application, when the upper pressure roller is raised to reduce the curvature of the flat steel and the pressure between the flat steel and the upper pressure roller is reduced, the push plate pushes the clamp block to deflect the clamp block to squeeze and support the inner wall of the flat steel, thereby increasing the friction force of the flat steel during transportation, thereby avoiding slipping of the flat steel during the cold bending process and ensuring the bending accuracy and processing efficiency of the flat steel. Moreover, when the upper pressure roller is lowered to increase the curvature of the flat steel and the pressure between the flat steel and the upper pressure roller is increased, the push plate pushes the clamp block to deflect in the opposite direction. The deflection of the clamp block not only cancels the squeezing support on the inner wall of the flat steel and avoids deformation of the inner wall of the flat steel due to excessive pressure, but also the clamp block can exert pressure on the side wall of the flat steel to prevent the flat steel from accumulating inner material due to excessive bending and then twisting, thereby improving the cold bending processing effect of the flat steel and ensuring the production quality of the toilet rack support ring.

[0015] In addition, the present application utilizes the transmission of the pushing assembly and the transmission unit to enable the state of the clamp to automatically switch as the bending angle of the flat steel changes. Therefore, during the bending process of the toilet frame support ring, it is possible to improve production efficiency while ensuring the processing quality of the parts, thereby achieving the effect of saving the production cost of toilet frame parts.

[0016] The width of the restraining groove formed between the lower pressure roller, the upper pressure roller and the sleeve can be adjusted, which makes it easy to process flat steels of different thicknesses through the device, thereby making the device have a wider range of applications. Moreover, when the flat steel to be processed is twisted and bent, by controlling the extension and retraction of the electric telescopic rod, the lower pressure roller and the sleeve can clamp the deformed flat steel, so that the flat steel can be restored to a straight state under the clamping force, thereby helping to improve the accuracy and quality of flat steel processing and reduce the scrap rate of materials.

[0017] The protective mechanism can close the slot where the clamp block on the upper pressing roller is located before the pressure between the flat steel and the upper pressing roller increases, thereby avoiding an uneven transition of the inner wall after the flat steel is pressed and bent, and further improving the cold bending effect of the flat steel.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technology in the embodiments of the present invention, a cold roll forming machine for producing toilet frame parts. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] like Figure 1-Figure 10As shown, the present invention provides a cold roll forming machine for producing toilet frame parts: it includes a driving body 10, a hydraulic rod 11 is fixedly installed on the top of the driving body 10, the telescopic end of the hydraulic rod 11 is fixedly connected to a lifting platform 12 sliding inside the driving body 10, a motor 15 is fixedly installed inside the driving body 10 and on the lifting platform 12, two lower pressing rollers 13 and an upper pressing roller 14 are arranged on the outer side of the driving body 10, and the upper pressing roller 14 is located directly above the two lower pressing rollers 13. When the flat steel is bent, the hydraulic rod 11 is controlled to telescope and adjust the lifting platform 12 according to the required bending degree. 2 and the height of the upper pressing roller 14, and then insert the flat steel between the upper pressing roller 14 and the two lower pressing rollers 13, and use the motor 15 to drive the two lower pressing rollers 13 to reverse and drive the upper pressing roller 14 to rotate forward, so as to drive the flat steel to pass through the gap between the upper pressing roller 14 and the two lower pressing rollers 13. During the conveying process, the flat steel is squeezed by the lower pressing roller 13 and the upper pressing roller 14 to realize bending processing. A reducer is generally installed between the motor 15 and the lower pressing roller 13 and the upper pressing roller 14 to increase the torque of the lower pressing roller 13 and the upper pressing roller 14 so that the lower pressing roller 13 and the upper pressing roller 14 have enough power to process the flat steel.

[0022] After the upper pressure roller 14 is raised, the distance between the lower pressure roller 13 and the upper pressure roller 14 increases, the curvature of the flat steel decreases, and the extrusion pressure received decreases. Conversely, after the upper pressure roller 14 is lowered, the distance between the lower pressure roller 13 and the upper pressure roller 14 decreases, the curvature of the flat steel increases, and the extrusion pressure received increases. When the flat steel is bent into a horseshoe-shaped toilet frame support ring, it is necessary to continuously adjust the curvature of the flat steel. In order to avoid the flat steel from slipping during the moving bending process due to the reduction of the extrusion pressure between the upper pressure roller 14 and the flat steel, the support mechanism 30 is also included. The support mechanism 30 includes a clamping block 31 rotatably connected to the interior of the upper pressure roller 14, and a plurality of clamping blocks 31 are equidistantly arranged around the axis of the upper pressure roller 14 in a circle, and a push plate 32 is slidably connected to the interior of the upper pressure roller 14; Reference Fig.10 When the hydraulic rod 11 drives the upper pressing roller 14 to rise and reduce the bending angle of the flat steel, the push plate 32 pushes the clamping block 31 to deflect, so that the clamping block 31 supports and clamps the inner side of the flat steel. At this time, the upper pressing roller 14 increases the friction between the inner wall of the flat steel through the clamping block 31, so that the rotation of the upper pressing roller 14 can smoothly drive the flat steel to move, realize the flat steel bending process, and avoid slipping and reduced bending accuracy when the flat steel moves; When the hydraulic rod 11 drives the upper pressure roller 14 to descend to increase the bending angle of the flat steel, the push plate 32 pushes the clamp block 31 in the opposite direction to deflect, so that the clamp block 31 applies pressure to the outer wall of the flat steel. At this time, the deflection of the clamp block 31 no longer squeezes the inner wall of the flat steel, avoiding excessive squeezing between the clamp block 31 and the flat steel, which causes dents on the inner wall of the flat steel, thereby improving the bending processing effect of the flat steel. At the same time, since the curvature of the flat steel increases at this time, during the bending process, the flat steel is prone to tilt and twist due to the accumulation of inner material. Applying pressure to the outer wall of the flat steel by the clamp block 31 can prevent the flat steel from tilting and twisting in addition to bending, thereby further improving the cold bending effect of the flat steel.

[0023] Reference Figure 5 and Figure 7 The upper pressing roller 14 is provided with a pushing assembly 33 inside, and a transmission unit 34 is provided on one side of the pushing assembly 33. The pushing assembly 33 includes a threaded column 332 rotatably connected to the upper pressing roller 14. The external thread of the threaded column 332 is connected to a connecting frame 331 rotatably connected to the push plate 32. The connecting frame 331 is internally slidably connected with a positioning rod 333. The positioning rod 333 is rotatably connected to the upper pressing roller 14. The positioning rod 333 limits the rotation of the connecting frame 331. The threaded column 332 rotates to drive the connecting frame 331 to move horizontally, and the push plate 32 is pushed by the connecting frame 331 to realize the horizontal movement of the push plate 32. The upper pressing roller 14 drives the clamping block 31 and the push plate 32 to rotate during the rotation, and the connecting frame 331 does not rotate with the push plate 32.

[0024] Reference Figure 3 The transmission unit 34 includes a gear 341 fixed to the outer end of the threaded column 332, and one side of the gear 341 is meshed with a toothed plate 342. When the upper pressure roller 14 is not adjusted in height, the gear 341 meshed with the toothed plate 342 will not rotate, so the pushing component 33 will not push the push plate 32, so that the clamping block 31 can maintain a stable state. When the upper pressure roller 14 is adjusted in height, the upper pressure roller 14 moves to drive the threaded column 332 and the gear 341 to move, so that the gear 341 rolls on the toothed plate 342. The movement causes the threaded column 332 to rotate, and the pushing assembly 33 pushes the push plate 32 to realize the deflection of the clamp block 31. When the upper pressure roller 14 moves upward, the gear 341 rotates forward to deflect the clamp block 31 to support and clamp the inner side of the flat steel. When the upper pressure roller 14 moves downward, the gear 341 rotates reversely to deflect the clamp block 31 to apply pressure to the outer wall of the flat steel, thereby realizing the adaptive change of the state of the clamp block 31 according to the bending angle of the flat steel, so that the clamp block 31 can play an anti-slip and anti-twist effect.

[0025] Reference Figure 2 and Figure 3Some flat steels may bend and twist laterally under the action of external forces during the early processing or transportation, making it impossible to perform press bending. In order to make full use of these materials and reduce the scrap rate, a straightening assembly 20 is also included. The straightening assembly 20 includes a sleeve 21 that is slidably connected to the outside of the lower pressing roller 13 and the upper pressing roller 14 and fixed to the drive shaft of the motor 15. A groove for constraining the flat steel is formed between the lower pressing roller 13 or the upper pressing roller 14 and the sleeve 21. When the flat steel is pressed and bent, the flat steel can be positioned through the groove to prevent it from tipping over during the bending. In order to facilitate the insertion of the flat steel into the groove, the width of the groove is generally greater than the thickness of the flat steel, and there are usually raised rust spots on the outer wall of the flat steel. Therefore, it is difficult for the inner wall of the groove to fully fit with the flat steel, which makes the anti-tilting and torsion effect of the groove limited. The design of the clamp 31 The arrangement can further enhance the anti-tilting and anti-twisting effect during flat steel bending. One side of the driving body 10 is fixedly connected to a front frame plate 22 fixed to the tooth plate 342, and one side of the lower pressure roller 13 is rotatably connected to a connecting plate 23. An electric telescopic rod 24 with a telescopic end fixed to the connecting plate 23 is fixedly installed on the front frame plate 22. By controlling the extension and retraction of the electric telescopic rod 24, the connecting plate 23 and the lower pressure roller 13 can be driven to move, and the width of the groove between the lower pressure roller 13 and the sleeve 21 can be adjusted to facilitate bending of flat steels of different thicknesses. After increasing the width of the groove, transversely bent and slightly twisted flat steels can also be placed in the groove, and then the electric telescopic rod 24 is controlled to extend so that the lower pressure roller 13 and the sleeve 21 clamp the flat steel in the groove, and the flat steel is straightened to facilitate subsequent flat steel bending.

[0026] Reference Figure 7 , Figure 8 and Fig. 9When squeezing the inner wall of the flat steel, the clamping block 31 needs to penetrate the outer wall of the upper pressing roller 14, so that there is a slot hole on the outside of the upper pressing roller 14. When the squeezing force between the upper pressing roller 14 and the flat steel increases, the inner side of the flat steel is prone to an uneven transition. In order to avoid this problem, a protective mechanism 40 is also included. The protective mechanism 40 includes a mounting frame 41 slidably connected to the inside of the upper pressing roller 14, and a baffle 42 is fixedly connected to the mounting frame 41. A plurality of baffles 42 are respectively slidably connected to each slot hole of the upper pressing roller 14. One end of the threaded column 332 is fixedly connected to a spiral groove rod 43 penetrating the mounting frame 41. A connecting unit 44 is arranged on the outside of the spiral groove rod 43. The connecting unit 44 includes a sleeve ring 441 slidably connected to the inside of the upper pressing roller 14 and sleeved on the outside of the spiral groove rod 43. The inner wall of the sleeve ring 441 is provided with a convex block embedded in the spiral groove of the spiral groove rod 43. When the height of 14 is adjusted, the threaded column 332 rotates to drive the spiral groove rod 43 to rotate. The rotation of the spiral groove rod 43 drives the ring 441 to slide inside the upper pressure roller 14 through the protrusion. A spring 442 is fixedly connected between the ring 441 and the mounting frame 41. The movement of the ring 441 drives the spring 442 to push the mounting frame 41, thereby driving the baffle 42 to open or close the slot hole of the upper pressure roller 14. Through the transmission of the connecting unit 44 and the spiral groove rod 43, the baffle 42 can automatically close the slot hole of the upper pressure roller 14 when the upper pressure roller 14 is lowered to increase the pressure on the flat steel, thereby improving the automation degree of the device and accelerating the processing efficiency. The purpose of setting the spring 442 is to enable the baffle 42 to continue to move after the slot hole is closed, so that the spiral groove rod 43, the ring 441 and the threaded column 332 can continue to move, so that the upper pressure roller 14 can continue to be lowered downward to increase the pressure.

[0027] Reference Figure 5 and Figure 6 In order to make the slot width between the upper pressure roller 14 and the sleeve 21 match the slot between the lower pressure roller 13 and the sleeve 21, it also includes an adjusting component 50 for adjusting the position of the upper pressure roller 14, the adjusting component 50 includes a slider 51 slidably connected to the inside of the front frame plate 22 and fixed to the positioning rod 333, the slider 51 is slidably connected to the inside of the square rod 53, the outer end of the square rod 53 is fixedly connected to a fixing frame 54 rotatably connected to the upper pressure roller 14, the slider 51 is internally threadedly connected to a screw rod 52 rotatably connected to the square rod 53, the screw rod 52 is manually rotated to drive the square rod 53 to slide inside the slider 51, and the upper pressure roller 14 is driven to move in the horizontal direction through the fixing frame 54 to adjust the slot width between the upper pressure roller 14 and the sleeve 21, and the fixing frame 54 and the slider 51 can move up and down with the upper pressure roller 14, drive the positioning rod 333 to move, so that the positioning rod 333 can always position the connecting frame 331.

[0028] Working principle: Control the electric telescopic rod 24 to contract to drive the connecting plate 23 and the lower pressure roller 13 to move, increase the width of the groove between the lower pressure roller 13 and the sleeve 21, put the flat steel with transverse bending and slight twist into the groove, and then control the electric telescopic rod 24 to extend so that the lower pressure roller 13 and the sleeve 21 clamp the flat steel in the groove, straighten the flat steel, and then pull the flat steel out, manually rotate the screw rod 52 to drive the square rod 53, the fixing frame 54 and the upper pressure roller 14 to move, so that the width of the groove between the upper pressure roller 14 and the sleeve 21 is the same as the thickness of the flat steel, and then control the hydraulic rod 11 to extend or contract, drive the lifting platform 12 and the motor 15 inside it as well as the sleeve 21 and the upper pressure roller 14 to move, and adjust the height of the upper pressure roller 14 to control the initial bending degree of the flat steel; The upper pressing roller 14 and the two lower pressing rollers 13 are driven to rotate by the motor 15 respectively. The upper pressing roller 14 rotates in the opposite direction to the lower pressing roller 13. One end of the flat steel is put into the groove and extends between the upper pressing roller 14 and the two lower pressing rollers 13. Under the action of the friction between the lower pressing roller 13, the upper pressing roller 14 and the flat steel, the flat steel is moved and transported between the upper pressing roller 14 and the two lower pressing rollers 13. At the same time, the flat steel is bent under the squeezing of the upper pressing roller 14 through the two lower pressing rollers 13. When the upper pressing roller 14 is raised to reduce the bending degree of the flat steel, the upper pressing roller 14 is raised to drive the threaded column 332, the gear 341, the fixing frame 54, the square rod 53, the slider 51 and the positioning rod 333 to move upward, and the gear 341 rolls and rotates on the toothed plate 342, and the gear 341 drives the threaded column 332 and the spiral groove rod 43 to rotate, and the spiral groove rod 43 rotates through the protrusion to drive the collar 441 to slide inside the upper pressing roller 14, and the movement of the collar 441 drives the spring 442 to push the mounting frame 41, and drives the baffle 42 to move and open the slot hole of the upper pressing roller 14, and then the threaded column 332 rotates to make the connecting frame 331 positioned under the positioning rod 333 move in the direction close to the spiral groove rod 43, and drives the push plate 32 to push the clamping block 31 to deflect, so that the clamping block 31 extends out of the slot hole to squeeze the inner wall of the flat steel, thereby increasing the friction force during the flat steel transportation and avoiding slipping; When the upper pressure roller 14 is lowered to increase the curvature of the flat steel, according to the above principle, the baffle 42 closes the slot of the upper pressure roller 14, and the clamping block 31 deflects in the opposite direction to squeeze the outer wall of the flat steel to prevent the flat steel from experiencing uneven transition, tilting and distortion of the inner wall due to excessive pressure.

[0029] The above is only a preferred specific implementation of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes to a cold-bending forming machine for producing toilet frame parts and its inventive concept according to the technology of the present invention, which should be covered by the protection scope of the present invention.
