Description

Technical Field

[0001] This utility model relates to the field of roller press frames, and in particular to an adjustable roller press frame for forming straight seam welded pipes. Background Technology

[0002] Straight seam welded pipe is a pipe made by welding strip steel into straight seams on high-frequency welding equipment. It is named for the straight line formed by the weld.

[0003] In the production and processing of straight seam welded pipes, roll forming is a crucial step, and the performance of the roll forming machine, as the core equipment in this step, directly affects the forming quality and production efficiency of the welded pipes.

[0004] In traditional straight seam welded pipe forming roller press frames, the crossbeam height of most frames is fixed, which cannot be flexibly adjusted according to the forming requirements of welded pipes of different specifications. This means that a set of frames can often only be adapted to the processing of one or a few specific specifications of welded pipes. When it is necessary to produce welded pipes of different diameters and wall thicknesses, the entire frame must be replaced or complex modifications must be made, which not only increases production costs but also seriously affects the continuity and efficiency of production. To address these issues, an adjustable roller press frame for straight seam welded pipe forming is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an adjustable roller press frame for straight seam welded pipe forming, which aims to improve the problems of poor adjustment flexibility and inconvenient operation in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an adjustable roller press frame for forming straight seam welded pipes, comprising a base, a connecting beam fixedly connected to the rear side of the base, an upright fixedly connected to the upper side of the base, a limiting groove provided on the inner wall of the upright, a crossbeam sliding on the inner wall of the limiting groove, a slot provided on the inner wall of the crossbeam, a connecting rod sliding on the inner wall of the upright, an installation cap connected to the front side of the upright by bolts, and a pre-fixing component provided on the front side of the upright for pre-fixing the crossbeam.

[0007] As a further description of the above technical solution:

[0008] The pre-fixing assembly includes a support plate, the outer wall of which is snapped onto the inner wall of the upright, and a limit rod is elastically connected to the inner wall of the support plate by a spring.

[0009] As a further description of the above technical solution:

[0010] One end of the spring is fixedly connected to the inner wall of the bearing plate, and the other end of the spring is fixedly connected to the left side of the limiting rod.

[0011] As a further description of the above technical solution:

[0012] The outer wall of the limiting rod is slidably connected to the inner wall of the bearing plate, and the right outer wall of the limiting rod is engaged with the inner wall of the upright.

[0013] As a further description of the above technical solution:

[0014] The outer wall of the connecting rod is engaged with the inner wall of the slot, and the front side of the connecting rod contacts the rear side of the mounting cap.

[0015] As a further description of the above technical solution:

[0016] A through hole is provided on the inner front wall of the upright, and the diameter of the through hole in the upright is the same as that of the connecting rod.

[0017] As a further description of the above technical solution:

[0018] The bearing plate is Z-shaped, and a receiving groove is provided on the inner wall of the bearing plate. The upper side of the bearing plate is in contact with the lower side of the crossbeam.

[0019] As a further description of the above technical solution:

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figures 1-3 This utility model provides an embodiment of an adjustable roller press frame for straight seam welded pipe forming, comprising a base 1. The base 1 serves as the basic support component of the entire frame, used to stably support all structures above it. Two symmetrically arranged bases 1 ensure the overall balance and stability of the frame, preventing tilting or swaying during the roller pressing process. The bases 1 are arranged as two symmetrical bases, and a connecting beam 2 is fixedly connected to the rear side of each base 1, connecting the two symmetrical bases 1 into a whole. A vertical rod 4 is fixedly connected to the upper side of each base 1, extending upwards perpendicularly to the base 1, used to support and install crossbeams 8, etc. The upright 4 is a crucial supporting component connecting the base 1 and the upper structure. A through hole is provided on the inner front wall of the upright 4, providing a channel for the installation of the connecting rod 3. This allows the connecting rod 3 to pass through the upright 4 and mate with the crossbeam 8. The diameter of the through hole in the upright 4 is the same as that of the connecting rod 3, ensuring a tight fit between the connecting rod 3 and the through hole, preventing loosening of the connecting rod 3 within the hole, and ensuring the stability of the connection. A limiting groove 5 is provided on the inner wall of the upright 4. The limiting groove 5 restricts and guides the sliding direction of the crossbeam 8, ensuring that the crossbeam 8 can only move up and down along the direction of the limiting groove 5, guaranteeing the accuracy of its movement trajectory.

[0032] Reference Figures 1-3A crossbeam 8 slides on the inner wall of the limiting groove 5. The crossbeam 8 can slide within the limiting groove 5 to adjust its height position according to the forming requirements of the straight seam welded pipe, thereby adapting to the roll forming of welded pipes of different specifications. A slot 10 is provided on the inner wall of the crossbeam 8. The slot 10 is used to cooperate with the connecting rod 3. By inserting the connecting rod 3 into the slot 10 at different positions, the height of the crossbeam 8 is fixed. A connecting rod 3 slides on the inner wall of the upright 4. The connecting rod 3 can slide on the inner wall of the upright 4, making it easy to insert into the slot 10 of the crossbeam 8, thus connecting the upright 4 and the crossbeam 8 and fixing the position of the crossbeam 8. The outer wall of the connecting rod 3 is engaged with the inner wall of the slot 10, and the front side of the connecting rod 3 contacts the rear side of the mounting cap 6. The front side of the upright 4 is connected to a mounting cap 6 by bolts 9. The mounting cap 6, through contact with the connecting rod 3, can limit the connecting rod 3 and prevent it from falling forward from the through hole of the upright 4. The bolt 9 connection method facilitates the disassembly and installation of the mounting cap 6, and makes it convenient to adjust or maintain the connecting rod 3. The front side of the upright 4 is provided with a pre-fixing component. Before the crossbeam 8 is officially fixed by the connecting rod 3, the pre-fixing component plays a temporary fixing role for the crossbeam 8, which facilitates the operator to perform subsequent precise adjustment and fixing operations. The pre-fixing component is used for the pre-fixing of the crossbeam 8. After the crossbeam 8 is adjusted to the approximate position, it is initially fixed to prevent the crossbeam 8 from shifting position during the installation of the connecting rod 3.

[0033] Reference Figures 2-4 The pre-fixing assembly includes a support plate 7, which is the main load-bearing component of the pre-fixing assembly and is used to directly support the lower side of the crossbeam 8. The support plate 7 is Z-shaped, and the Z-shaped structure allows the support plate 7 to cooperate with both the upright 4 and the crossbeam 8. It can be snapped into the inner wall of the upright 4 and stably support the crossbeam 8. The inner wall of the support plate 7 has a receiving groove, which provides installation space for the spring 12 and the limiting rod 11, ensuring that they can work normally inside the support plate 7. The upper side of the support plate 7 contacts the lower side of the crossbeam 8. Through this contact, the support plate 7 can provide upward support force for the crossbeam 8, realizing the initial lifting and pre-fixation of the crossbeam 8. The outer wall of the support plate 7 is snapped into the inner wall of the upright 4. The snapping method makes the support plate 7... The plate 7 can be fixed at a specific position on the upright 4, and the height of the bearing plate 7 can be adjusted as needed. The inner wall of the bearing plate 7 is elastically connected to the limiting rod 11 by the spring 12. The elasticity of the spring 12 allows the limiting rod 11 to extend and retract within a certain range, thereby realizing the engagement or disengagement of the limiting rod 11 with the inner wall of the upright 4. The outer wall of the limiting rod 11 is slidably connected to the inner wall of the bearing plate 7, and the right outer wall of the limiting rod 11 is engaged with the inner wall of the upright 4. Through the engagement of the limiting rod 11 with the inner wall of the upright 4, the bearing plate 7 can be fixed on the upright 4, preventing the bearing plate 7 from sliding when supporting the crossbeam 8. One end of the spring 12 is fixedly connected to the inner wall of the bearing plate 7, and the other end of the spring 12 is fixedly connected to the left side of the limiting rod 11.

[0034] Working Principle: During operation, the adjustable roller press frame first establishes a stable foundation support structure through two symmetrically arranged bases 1 and connecting beams 2, ensuring overall balance and stability during the roller pressing process. When adjusting the height of the crossbeam 8 according to the straight seam welded pipe specifications, the pre-fixing assembly is operated first: the Z-shaped bearing plate 7 is slid to a suitable position on the inner wall of the upright 4. At this time, the spring 12 inside the bearing plate 7 pushes the limiting rod 11 into the inner wall of the upright 4, temporarily fixing the bearing plate 7. Then, the crossbeam 8 is placed on top of the bearing plate 7, using the support of the bearing plate 7 to achieve pre-fixation of the crossbeam 8, preventing it from shifting during subsequent adjustments. The connecting rod 3 is moved into the upright 4, passing through the through hole of the upright 4 and engaging in the corresponding slot 10 on the inner wall of the crossbeam 8, thus fixing the height position of the crossbeam 8. Afterwards, the mounting cap 6 is fixed to the front side of the upright 4 using bolts 9. The contact between the mounting cap 6 and the connecting rod 3 restricts its forward detachment, further ensuring connection stability. If further adjustments are needed, the mounting cap 6 can be removed, the connecting rod 3 can be pulled out, and the pre-fixed components can be released from their restriction on the crossbeam 8.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
