Description

Technical Field

[0001] The present application relates to the technical field of barrel processing, and in particular to a barrel processing device. Background Art

[0002] In the fabrication of non-standard steel structures, rolling cylinders is a common workshop task. Traditionally, this process is performed using a plate rolling machine. When processing conical cylinders, a crane is required to assist in lifting the cylinder ends to facilitate the rolling process. Using a crane during this process can easily cause the crane to tilt, which not only damages the crane and increases maintenance costs, but also poses a significant safety hazard. Utility Model Content

[0003] In order to solve the above technical problems, the present application provides a cylinder processing device, including a plate rolling machine, a roller support frame, a cylinder roller and an angle adjustment mechanism. The plate rolling machine has a plurality of mutually parallel extrusion rollers for rolling steel plates to form a cylinder. The roller support frame and the plate rolling machine are arranged side by side in the transverse direction. The cylinder roller is arranged directly above the plate rolling machine and is used to support the inner wall of the cylinder. One end of the cylinder roller is rotatably connected to the roller support frame, and the other end can swing up and down. The angle adjustment mechanism is used to drive the cylinder roller to swing up and down, change the angle between the cylinder roller and the extrusion roller, and can adjust the taper of the cylinder when processing the cylinder, so that cylinders with different tapers can be processed. It not only has high processing efficiency, but also is convenient and safe to use.

[0004] In some embodiments, the angle adjustment mechanism includes a first hydraulic cylinder, one end of which is rotatably connected to the cylinder roller, and the other end of which is movably connected to the roller support frame.

[0005] In some embodiments, the roller support frame includes a column and a plurality of triangular support frames arranged along the circumference of the column. Each triangular support frame includes a bottom crossbeam and side diagonal braces. The bottom crossbeam is arranged perpendicular to the column, one end of the bottom crossbeam is connected to the column, and the other end is connected to the side diagonal braces. The side diagonal braces are arranged obliquely to the column, one end of the side diagonal brace is connected to the column, and the other end is connected to the bottom crossbeam. Preferably, one triangular support frame can be arranged on each of the three sides to enhance the strength and rigidity of the roller support frame, effectively improving processing accuracy and service life.

[0006] In some embodiments, the angle adjustment mechanism also includes an angle indicating component for marking the up and down swing angle of the cylinder roller, which facilitates the staff to set the angle between the cylinder roller and the extrusion roller according to the drawing to process the cylinder with different tapers.

[0007] In some embodiments, the angle indicator assembly may include a scale with angle values ​​engraved on its surface and an angle pointer for reading the angle. The scale is a semicircular ring plate with a pointer slot in the middle. One end of the scale is flush with and fixed to the cylindrical roller, while the other end passes through the roller support frame. The center of the scale is located at the pivotal connection between the cylindrical roller and the roller support frame. The angle pointer is inserted into the pointer slot and fixedly connected to the roller support frame. As the cylindrical roller swings up and down, the scale moves relative to the angle pointer, allowing the angle pointer to point to different angle values.

[0008] In some embodiments, the roller support frame further includes a height adjustment mechanism for adjusting the height of the cylinder roller and the angle adjustment mechanism, so that the staff can easily set the height of the cylinder roller between the extrusion rollers according to the drawings to process cylinders of different sizes.

[0009] In some embodiments, the height adjustment mechanism includes a second hydraulic cylinder and a lifting block. One end of the second hydraulic cylinder is connected to the lifting block, and the other end is connected to the column. The lifting block is slidably connected to the column. The cylindrical roller is rotatably connected to the lifting block, and the angle adjustment mechanism is movably connected to the lifting block. The second hydraulic cylinder can drive the lifting block to slide up and down along the column, thereby driving the cylindrical roller and the angle adjustment mechanism to move up and down.

[0010] In some embodiments, the sliding connection between the lifting slider and the column is achieved through a protrusion and a slide groove. The lifting slider is provided with a limit protrusion, and the column is provided with a slide groove at a position corresponding to the limit protrusion. The limit protrusion is inserted into the slide groove and can slide along the slide groove.

[0011] In some embodiments, the cylinder roller is provided with at least one rolling wheel in its axial direction, which can change the sliding contact between the cylinder and the cylinder roller into rolling contact, thereby reducing friction resistance and improving processing efficiency and precision.

[0012] The beneficial effects of this application are as follows: by providing a cylinder roller with adjustable pitch angle above the plate rolling machine, the cylinder is supported, improving the safety and efficiency of the cylinder processing process. An angle indicator component and a height adjustment mechanism can also be provided to change the angle and distance between the cylinder roller and the extrusion roller, enabling the processing of cylinders of different tapers and sizes, further improving production efficiency.

[0019] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other alternative implementations obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0020] Figure 1 The first embodiment of the present application is shown, which provides a cylinder processing device, including a plate rolling machine 1, a roller support frame 2, a cylinder roller 3, and an angle adjustment mechanism. The plate rolling machine 1 has a plurality of mutually parallel squeezing rollers 11, and the roller support frame 2 and the plate rolling machine 1 are arranged side by side in the transverse direction. The cylinder roller 3 is arranged directly above the plate rolling machine 1, and one end of the cylinder roller 3 is rotatably connected to the roller support frame 2, and the other end can swing up and down. After the plate rolling machine 1 bends the steel plate into a cylinder 10, the cylinder roller 3 can contact the inner wall of the cylinder 10 and support the cylinder 10. The angle adjustment mechanism includes a first hydraulic cylinder 4, one end of which is rotatably connected to the cylinder roller 2, and the other end is rotatably connected to the roller support frame 2. The first hydraulic cylinder 4 can realize the up and down swing of the cylinder roller 3 by changing the extension and contraction amount, change the angle between the cylinder roller 3 and the squeezing roller 11, and realize the function of processing cylinders with different tapers or cylindrical cylinders.

[0021] In some embodiments, the angle adjustment mechanism may also be driven by a rack and pinion, or a worm gear.

[0022] Figure 2 and Figure 3 The second embodiment of the present application is shown. The roller support frame 2 includes a column 25 and a plurality of triangular support frames 26 arranged along the circumference of the column 25, preferably three. Each triangular support frame 26 includes a bottom crossbeam 261 and a side diagonal brace 262. The bottom crossbeam 261 is arranged perpendicular to the column 25, one end of the bottom crossbeam 261 is connected to the column 25, and the other end is connected to the side diagonal brace 262. The side diagonal brace 262 is arranged obliquely to the column 25, one end of the side diagonal brace 262 is connected to the column 25, and the other end is connected to the bottom crossbeam 261. The triangular support frame 26 can strengthen the strength and rigidity of the column 25, and can effectively improve the processing accuracy and service life.

[0023] In the second embodiment, as Figure 2 and Figure 3 As shown, the angle adjustment mechanism also includes an angle indicating assembly 41 for marking the angle between the cylinder roller 3 and the roller support frame 2. The angle indicating assembly 41 includes a scale 411 with an angle value engraved on the surface and an angle pointer 412 for reading the angle. The scale 411 is a semicircular ring plate with a pointer chute 413 in the middle. One end of the scale 411 is flush with the cylinder roller 3 and fixed on the cylinder roller 3, and the other end passes through the roller support frame 2. The center of the scale 411 is located at the rotational connection between the cylinder roller 3 and the roller support frame 2. The angle values ​​on both sides of the pointer chute 413 can be expressed in different units, such as degrees on one side and radians on the other side, which makes it easier for production personnel to calculate the processing dimensions of the cylinder. Angle pointer 412 includes a pointer 414 that accurately points to the angle scale on scale 411. Angle pointer 412 is inserted into pointer chute 411 and fixedly connected to roller support frame 2. As cylinder roller 3 swings up and down, scale 411 moves relative to angle pointer 412, allowing angle pointer 412 to point to different angles. Based on the indicated angle, production personnel can determine whether the angle between cylinder roller 3 and extrusion roller 11 meets the processing requirements of cylinder 10.

[0024] The angle indicating component 41 may also be in other forms, such as an electronic angle ruler, etc., as long as it can indicate the angle value, and the specific implementation method is not limited.

[0025] like Figure 4 and Figure 5As shown, as a further improvement, in the second embodiment of the present application, the roller support frame 2 also includes a height adjustment mechanism. The height adjustment mechanism includes a second hydraulic cylinder 21 and a lifting slider 22 slidably connected to the column 25. One end of the second hydraulic cylinder 21 is connected to the lifting slider 22, and the other end is connected to the column 25. The cylinder roller 3 is rotatably connected to the lifting slider 22, and the angle adjustment mechanism 5 is movably connected to the lifting slider 22. The second hydraulic cylinder 21 drives the lifting slider 22 to slide up and down along the column 25, thereby driving the cylinder roller 3 and the angle adjustment mechanism 5 to move up and down, thereby realizing the function of adjusting the distance between the cylinder roller 3 and the extrusion roller 11 on the plate rolling machine 1, thereby adapting to the processing needs of the rolls 10 of different sizes.

[0026] In this embodiment, if Figure 5 As shown, the sliding connection between the lifting slider 22 and the column 25 is achieved through a protrusion 221 and a slide groove 251. The lifting slider 22 is provided with a limit protrusion 221, and the column 25 is provided with a slide groove 251 at a position corresponding to the limit protrusion 221. The limit protrusion 221 is inserted into the slide groove 251 and can slide along the slide groove 251.

[0027] The sliding connection between the lifting slider 22 and the column 25 can also be achieved through the cooperation of a guide rail and a boss, or an optical axis and a through hole.

[0028] In addition to being driven by a hydraulic cylinder, the height adjustment mechanism can also be driven by mechanisms such as rack and pinion, worm gear, etc.

[0029] like Figure 2 As shown, in some embodiments, a plurality of rolling wheels 31 can be further provided on the cylinder roller 3 in its axial direction, which can change the sliding contact between the cylinder 10 and the cylinder roller 3 into rolling contact, thereby reducing friction resistance and improving processing efficiency and precision.

[0030] Finally, it should be noted that if the embodiments of the present application involve directional indications (such as up, down, left, right, front, back...), such directional indications are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0031] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present application, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0032] The above is only an implementation method of the present application and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the description and drawings of this application, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
