Description

Technical Field

[0001] The utility model relates to the field of metal processing machinery, in particular to a roller bending and cutting integrated device. Background Art

[0002] There are many ways to process metal profiles, including cold forming, which involves extruding the metal sheet through a series of rollers. Furthermore, some profiles with larger edge angles usually require stamping and bending after rolling to achieve the desired shape. The rolled section is then cut into the required length using a cutting device.

[0003] However, after the existing device processes the plate into a profile, there will be many burrs on the cutting position, which requires manual deburring and grinding; Figure 4 The profile 5 has inclined portions 51 on both sides and a protruding portion 52 in the middle. After the plate is rolled and bent, the inclined portions 51 are inclined upward and have multiple bends. There are overlapping parts in the vertical direction, which can easily cause uneven distribution of shear force and form more burrs on the edges. In addition, the upward inclination of the inclined portion 51 increases the vertical thickness of the cross-section, which can also easily form more burrs on the edges. Utility Model Content

[0004] The utility model provides a roller bending and cutting integrated device, which can effectively solve the above problems.

[0010] The first cutting assembly further includes a first lower template and a first lower mold base, and both the first lower template and the first lower mold base are provided with a waste trough.

[0011] As a further improvement, the lower end surface of the first upper pressing block covers the entire inclined portion, and when the first cutting assembly is pressed downward, the first upper pressing block and the first lower template clamp the inclined portion.

[0016] This device integrates rolling, bending, and cutting functions, enabling continuous production. Sheets are fed from left to right, passing through the rolling assembly, first cutting assembly, bending assembly, and second cutting assembly, eliminating the need for transfer between different equipment. This significantly saves production time and improves efficiency.

[0017] The configuration of the first and second cutting assemblies makes the cutting process more efficient. After the sheet is rolled, the first cutting assembly first cuts off the inclined portion, leaving the remaining protruding portion to facilitate the feeding and conveying of the sheet. After the sheet is stamped and bent, the second cutting assembly cuts off the remaining protruding portion in the middle, thus cutting out the complete profile. This step-by-step cutting method avoids the problem of excessive burrs caused by one-time cutting, effectively reducing burrs at the profile cut, eliminating the need for manual deburring and grinding, improving production efficiency, reducing the need for manual deburring, and lowering labor costs.

[0029] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the utility model for which protection is claimed, but merely represents selected embodiments of the present invention.

[0030] In the description of this utility model, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "plurality" means two or more, unless otherwise specifically specified.

[0031] Reference Figure 1-4 As shown, a rolling bending and cutting integrated device includes a continuous rolling rolling component 1 and a bending component 3, wherein the continuous sheet material is fed from left to right, and the rolling component 1 gradually rolls the bending shapes on the inclined parts 51 on both sides and the protruding part 52 in the middle through rollers of different shapes and sizes arranged therein, and the bending component 3 bends the larger bending part at one time and bends the inclined parts 51 on both sides toward the protruding part 52 in the middle to complete the bending.

[0032] The first cutting assembly 2 is arranged on the side of the rolling assembly 1 away from the incoming material, and the bending assembly 3 is arranged on the side of the first cutting assembly 2 away from the incoming material. Since the overall cross-sectional shape of the plate is still relatively flat after rolling, there is no overlapping part in the vertical direction, and most of the inclined portion 51 is still in a horizontal state. The first cutting assembly 2 cuts off the inclined portions 51 formed by rolling on both sides of the plate from top to bottom, and the remaining protrusions 52 are convenient for feeding and conveying the plate;

[0033] The second cutting assembly 4 is arranged on the right side of the bending assembly 3. After the plate is stamped and bent, the second cutting assembly 4 cuts off the remaining protrusion 52 in the middle of the plate from top to bottom to cut out a complete profile 5.

[0034] It should be noted that the first cutting component 2 only cuts the inclined portion 51, and cannot cut the inclined surfaces on both sides of the protrusion 52 at the same time. If the inclined surfaces on both sides are also cut off, only a flat surface will be left to connect the plates, and the plates still need to be transported from left to right. During the transportation process, the end of the plate will be suspended in the air, and the strength of the connection part will be insufficient and prone to bending. Leaving the inclined surfaces on both sides of the protrusion 52 during the first cutting can increase its force strength.

[0035] Specifically, to ensure the accuracy of cutting, the first cutting assembly 2 includes a first upper die base 21 and two first punches 26. The two first punches 26 are positioned above the inclined portions 51 on both sides. A first upper clamping plate 22 is provided on the lower end surface of the first upper die base 21. A first stop plate 23 elastically connected to the first upper die base 21 is provided on the lower end surface of the first upper clamping plate 22. A spring is provided between the first stop plate 23 and the first upper die base 21, and the spring passes through the first upper clamping plate 22. One end of the first punch 26 is fixed to the lower end surface of the first upper die base 21 through the first upper clamping plate 22, and the other end passes through the first stop plate 23. A first upper pressing block 27 is further provided on both sides of the lower end surface of the first stop plate 23 near the first punch 26. When the first cutting assembly 2 is in the mold opening state, the lower end surface of the first upper pressing block 27 is lower than the first punch 26.

[0036] The first cutting assembly 2 further includes a first lower template 24 and a first lower template base 25 . Both the first lower template 24 and the first lower template base 25 are provided with waste grooves.

[0037] It should be noted that when the first upper die base 21 moves downward, the first upper pressure block 27 first contacts the sheet material and clamps the sheet material through the first lower template 24 to prevent the sheet material from shifting during cutting and avoid large dimensional errors. The first upper die base 21 continues to move downward, and the first punch 26 cuts the sheet material.

[0038] Specifically, since the inclined portion 51 has a bent structure, in order to prevent the inclined portion 51 from deforming near the incision position during cutting, the lower end surface of the first upper pressing block 27 covers the entire inclined portion 51. When the first cutting component 2 is pressed down, the first upper pressing block 27 and the first lower template 24 clamp the inclined portion 51.

[0039] Specifically, in order to better fit the shape of the inclined portion 51, two first inserts 243, two second inserts 242 and two third inserts 241 are embedded in the first lower template 24. The upper end faces of the first insert 243, the second insert 242 and the third insert 241 are all higher than the upper end face of the first lower template 24, and the upper end faces of the first insert 243, the second insert 242 and the third insert 241 are all fitted with the lower end face of the plate. This can also reduce the manufacturing difficulty of the first lower template 24 and facilitate processing and size adjustment. A first groove is provided on the side of the first insert 243, and a second groove is provided on the side of the third insert 241 to avoid the first punch 26.

[0040] Specifically, in order to enable the upper and lower dies of the first cutting component 2 to be accurately aligned during the cutting process and to ensure the dimensional accuracy and shape requirements of the stamping parts, the first cutting component 2 also includes a guide column, the top of which is fixed to the first upper die base 21, and the guide column passes through the first upper clamping plate 22, the first stop plate 23, the first lower template 24 and the first lower die base 25 from top to bottom.

[0041] Specifically, in order to fix and drive the first cutting assembly 2, a frame 28 is further provided on the outside of the first cutting assembly 2, and a hydraulic cylinder 29 is provided on the top of the frame 28. The hydraulic cylinder 29 drives the first upper die base 21 to move up and down.

[0042] Specifically, the second cutting assembly 4 includes a second upper die base, a second upper clamping plate provided on the lower end surface of the second upper die base, a first stop plate 23 elastically connected to the second upper die base, a second punch, a second lower template and a second lower die base.

[0043] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
