Description

Technical Field

[0001] This utility model relates to the field of bending equipment technology, and more specifically, to a bending machine. Background Technology

[0002] In the metal processing field, bending machines are specialized equipment used to bend metal sheets, pipes, or profiles into arcs or circles. They are widely used in industries such as petrochemicals, building decoration, and hardware manufacturing, primarily in the manufacture of stainless steel water tower bases, chemical equipment, and domestic water facilities. Traditional bending machines mainly employ a three-roller symmetrical structure, using the downward pressure of the upper roller and the rotational motion of the side rollers to bend and shape the material. However, while existing technology can meet basic processing requirements, it still has the following drawbacks: for forming arcs of different diameters, manual reassembly and disassembly of the rollers are required to adjust the roller spacing, resulting in low efficiency. Furthermore, it typically only allows for fixed position adjustments and cannot make fine adjustments to the required curvature. Utility Model Content

[0003] Therefore, in order to solve the problem of low efficiency in forming arcs of different diameters using traditional bending equipment, this utility model provides a bending machine, the specific technical solution of which is as follows:

[0004] A bending machine includes a processing table, a lower pressure roller, and multiple bending roller groups. A guide groove is formed on the processing table, and a drive device is installed on the processing table. A drive gear is sleeved on the output end of the drive device, and a buffer sleeve is provided inside the drive gear. The lower pressure roller is slidably mounted on the guide groove. Each bending roller group includes two driven rollers symmetrically arranged on both sides of the guide groove. A driven gear, which is connected to the drive gear, is sleeved on each driven roller. A forming gap is formed between the two driven rollers, and the forming gap of each bending roller group increases sequentially along the direction of the guide groove.

[0005] The aforementioned bending machine, by incorporating a buffer sleeve, reduces the contact vibration between the teeth during the meshing of the drive gears, effectively extending the service life of the drive gears and providing shock absorption. It also reduces noise during the drive gear transmission process. Furthermore, the inclusion of a lower pressure roller, which slides along a guide groove, allows for reciprocating adjustment of the spacing and angle between the rollers and different bending roller sets, thus adapting to the forming of arcs of varying diameters and improving processing efficiency. Finally, the availability of different forming spacings accommodates profiles of varying lengths, increasing the machine's versatility.

[0006] Furthermore, the processing table includes a base plate and an operating plate mounted on the base plate, the driving device is mounted on the base plate, the guide groove is formed through the operating plate, and the driven roller is rotatably inserted into the operating plate.

[0007] Furthermore, the processing table also includes a protective shell, which is disposed between the drive device and the operating plate. One end of the protective shell has an opening corresponding to the drive device, and the other end of the protective shell is detachably connected to the operating plate, forming a protective space between the two. The drive gear passes through the opening and extends into the protective space, and one end of the driven roller extends into the protective space and is fitted with the driven gear.

[0008] Furthermore, multiple heat dissipation vents are provided on both sides of the top of the protective shell.

[0009] Furthermore, the driven gears adjacent to each other on the same side mesh with each other, and the driven gears near the top of the guide groove on both sides mesh with the drive gear respectively.

[0010] Furthermore, the structure of the drive gear is the same as that of the driven gear. The drive gear includes a main tooth and a secondary tooth arranged coaxially. The buffer sleeve is disposed between the main tooth and the secondary tooth. The main tooth and the secondary tooth press and fix the buffer sleeve. Both the main tooth and the secondary tooth are provided with screw holes. The main tooth and the secondary tooth are fixed by bolts.

[0011] Furthermore, a control screw is threaded onto the top of the operating panel, and the lower pressure roller includes a lifting seat and a lower pressure roller body rotatably mounted on the lifting seat. A handle is sleeved on one end of the control screw, and the other end of the control screw is rotatably inserted into the top of the lifting seat. The lower pressure roller body includes a first roller sleeve and a second roller sleeve arranged coaxially, and an adjustment gap is formed between the first roller sleeve and the second roller sleeve. Several washers are detachably installed on the adjustment gap.

[0012] Furthermore, the driven roller includes a connecting shaft and a driven roller body. The connecting shaft is rotatably mounted on the operating plate. One end of the connecting shaft extends into the protective space and is fitted with a driven gear. The other end of the connecting shaft protrudes from the surface of the operating plate and is fixedly connected to the driven roller body. The structure of the driven roller body is the same as that of the pressing roller body.

[0013] Furthermore, positioning rods are inclinedly arranged on both sides of the operation panel, and the inclination angle of the positioning rods is parallel to the axis connecting line between the connecting shaft at the top and the connecting shaft at the bottom on the same side.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0025] In this utility model, "first" and "second" do not represent a specific quantity or order, but are merely used to distinguish names.

[0026] like Figures 1-3 As shown, a bending machine according to one embodiment of the present invention includes a processing table 1, a lower pressure roller 2, and multiple bending roller groups; a guide groove 11 is formed on the processing table 1, a drive device 4 is installed on the processing table 1, a drive gear 5 is sleeved on the output end of the drive device 4, and a buffer sleeve is provided inside the drive gear 5; the lower pressure roller 2 is slidably assembled on the guide groove 11; the bending roller group includes two driven rollers 3 symmetrically arranged on both sides of the guide groove 11, a driven gear 6 that is connected to the drive gear 5 is sleeved on the driven roller 3, a forming gap is formed between the two driven rollers 3, and the forming gap of each bending roller group increases sequentially along the setting direction of the guide groove 11.

[0027] The aforementioned bending machine, by incorporating a buffer sleeve, reduces the contact vibration between the teeth during the meshing of the drive gear 5, effectively improving the service life of the drive gear 5 and providing shock absorption. It also reduces noise during the transmission process of the drive gear 5. Furthermore, the inclusion of a lower pressure roller 2, which slides along the guide groove 11, allows for reciprocating adjustment of the spacing and angle between the rollers and different bending roller sets, thus adapting to the forming of arcs of different diameters and improving processing efficiency. Finally, the machine is equipped with different forming spacings to accommodate profiles of varying lengths, increasing its applicability.

[0028] Specifically, the guide groove 11 is arranged in a vertical direction.

[0029] In one embodiment, the processing table 1 includes a base plate and an operating plate mounted on the base plate. The drive device 4 is mounted on the base plate, the guide groove 11 is opened through the operating plate, and the driven roller 3 is rotatably inserted into the operating plate.

[0030] like Figure 1 and Figure 2 As shown, in one embodiment, the processing table 1 further includes a protective shell 12, which is disposed between the drive device 4 and the operating plate. One end of the protective shell 12 has an opening corresponding to the drive device 4, and the other end of the protective shell 12 is detachably connected to the operating plate, forming a protective space between them. The drive gear 5 passes through the opening and extends into the protective space, and one end of the driven roller 3 extends into the protective space and is fitted with a driven gear 6. Physical isolation prevents personnel or objects from directly contacting dangerous parts, avoids mechanical injury, improves the overall safety of the bending machine, and also helps to reduce operating noise.

[0031] like Figure 2 As shown, in one embodiment, multiple heat dissipation vents 121 are provided on both sides of the top of the protective shell 12. By increasing the airflow path, the heat generated during operation can be dissipated quickly.

[0032] In one embodiment, adjacent driven gears 6 on the same side mesh with each other, and the driven gears 6 near the top of the guide groove 11 mesh with the drive gears 5 respectively. In this way, a single drive gear 5 can complete the transmission control between multiple driven gears 6.

[0033] like Figure 3 and Figure 5 As shown, in one embodiment, the structure of the drive gear 5 is the same as that of the driven gear 6. The drive gear 5 includes a main tooth 51 and a secondary tooth 52 arranged coaxially. A buffer sleeve is disposed between the main tooth 51 and the secondary tooth 52. The main tooth 51 and the secondary tooth 52 press and fix the buffer sleeve. Both the main tooth 51 and the secondary tooth 52 are provided with screw holes and are fixed by bolts 53. The setting of the secondary tooth 52 increases the thickness of the drive gear 5 and the driven gear 6, thereby increasing the meshing surface (wearable surface) between the drive gear 5 and the driven gear 6, as well as between the driven gears 6 themselves. Therefore, it can effectively increase the service life of the drive gear 5 and the driven gear 6. Furthermore, due to the increased thickness of the drive gear 5, the driven gear 6 meshing on the drive gear 5 is less likely to disengage from the drive gear 5 after misalignment, which can effectively avoid the problem of teeth jamming due to poor contact.

[0034] like Figures 1-4 As shown, in one embodiment, a control screw 7 is threaded onto the top of the operating panel. The lower roller 2 includes a lifting seat 21 and a lower roller 2 body rotatably mounted on the lifting seat 21. A handle 71 is sleeved on one end of the control screw 7, and the other end of the control screw 7 is rotatably inserted into the top of the lifting seat 21. The lower roller 2 body includes a first roller sleeve 22 and a second roller sleeve 23 coaxially arranged, with an adjustment gap formed between the first roller sleeve 22 and the second roller sleeve 23. Several washers 8 are detachably installed on the adjustment gap. Thus, by providing the control screw 7, when the control screw 7 is rotated, the position of the lifting seat 21 on the guide groove 11 is adjusted by utilizing the threaded arrangement of the control screw 7 on the operating panel, thereby adjusting the processing position of the lower roller 2 body. By providing the adjustment gap, different numbers of washers 8 can be reciprocally installed and removed within the adjustment gap, thereby adjusting the combined width of the washers 8 on the adjustment gap, which is beneficial for adapting to profiles of different thicknesses and increasing the applicability of the bending machine.

[0035] In one embodiment, the driven roller 3 includes a connecting shaft and a driven roller 3 body. The connecting shaft is rotatably mounted on the operating plate. One end of the connecting shaft extends into the protective space and is fitted with a driven gear 6. The other end of the connecting shaft protrudes from the surface of the operating plate and is fixedly connected to the driven roller 3 body. The structure of the driven roller 3 body is the same as the structure of the lower pressure roller 2 body.

[0036] In one embodiment, positioning rods 13 are inclinedly arranged on both sides of the operating panel. The inclination angle of the positioning rods 13 is parallel to the axis connecting the top and bottom connecting shafts on the same side. The positioning rods 13 can provide a certain lateral support force for the profile to be processed, preventing the profile from tilting during processing, thereby improving the stability of profile bending.

[0037] like Figure 1 As shown, in one embodiment, the bending machine also includes a storage box 9 for storing the washers 8. The storage box 9 is located at the bottom of the processing table 1, and an opening and closing cover is hinged to the side wall of the storage box 9. This makes full use of space, avoids the waste of space caused by the messy stacking of the washers 8, and also reduces the time spent by personnel searching for them.

[0038] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0039] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
