Description

Technical Field

[0001] This utility model relates to the field of galvanized pipe production and processing technology, and in particular to an automatic grooving machine for galvanized pipe processing. Background Technology

[0002] Galvanized pipe, also known as galvanized welded steel pipe, is a type of pipe with a zinc layer coated on its surface by hot-dip galvanizing or electro-galvanizing. The zinc layer on the surface of the galvanized pipe effectively isolates the air and moisture from the steel pipe substrate, slows down the oxidation and corrosion rate of the steel pipe, and extends its service life. This allows the galvanized pipe to maintain good performance in humid or corrosive environments. Compared with ordinary steel pipe, it has higher durability. A grooving machine is required for its processing and production.

[0003] Grooving machines primarily transmit power to pressure rollers or molds via mechanical or hydraulic transmission. When the pipe is placed on the machine's worktable and fixed in position, the pressure rollers or molds apply uniform pressure to the pipe surface under power, causing localized plastic deformation and forming grooves of specific shapes and sizes. Existing grooving machines suffer from issues such as pressure roller wear, insufficient transmission precision, or unstable control systems, leading to groove dimensions that do not match the design, affecting the fit and sealing of pipe fittings. Current solutions involve selecting pressure roller materials with good wear resistance, such as carbide rollers, to improve wear resistance and precision retention. High-precision gears and lead screws are also used to reduce transmission errors. However, dust and dirt still adhere to the grooving area of ​​the workpiece, affecting the grooving effect and reducing accuracy. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides an automatic grooving machine for galvanized pipe processing, which aims to improve the problem in the prior art where dust and dirt adhere to the grooving position of the processed parts, thus affecting the grooving effect of the grooving equipment and reducing the grooving accuracy.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an automatic grooving machine for galvanized pipe processing, comprising a work frame, a grooving device fixedly connected to the top wall of the work frame, a fixed plate fixedly connected to the front right side of the grooving device, electric push rods fixedly connected to the front and rear sides of the inner wall of the fixed plate, a cleaning shell fixedly connected to the left end of the electric push rod, an mounting plate fixedly connected to the inner wall of the cleaning shell, bolts threadedly connected to the front and rear ends of the right side of the mounting plate, a cleaning brush threadedly connected to the left end of the bolts, and a collection mechanism provided on the left side of the bottom wall of the work frame, the collection mechanism being used to uniformly collect debris and cleaning dirt generated during operation.

[0006] As a further description of the above technical solution:

[0007] The collection mechanism includes an extraction fan, the top wall of which is fixedly connected to the left side of the bottom wall of the work frame.

A sponge board is fixedly connected to the rear inner wall of the collection box, and a filter plate is slidably installed on the front inner wall of the collection box. A connecting pipe is connected to the front of the collection box, and the front end of the connecting pipe is connected to an extraction shell. The rear side of the extraction shell is fixedly connected to the front of the work frame.

[0008] As a further description of the above technical solution:

[0009] The collection mechanism also includes a rubber ring, the inner wall of which is fixedly installed on the rear side of the outer wall of the connecting pipe, and the outer wall of which is fixedly connected to the front side of the collection box.

[0010] As a further description of the above technical solution:

[0011] A control switch is fixedly connected to the right side of the top wall of the work frame. The control switch is electrically connected to the grooving equipment, the electric push rod, and the extraction fan.

[0012] As a further description of the above technical solution:

[0013] A handle is fixedly connected to the right side of the filter plate, and a rubber sleeve is fixedly connected to the middle of the handle.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the cleaning shell is moved to the left by the electric push rod, and the cleaning brush fixed to the left side of the mounting plate is moved synchronously. So when the grooving equipment drives the galvanized pipe to rotate, the cleaning brush in the fixed position can clean the rotating galvanized pipe, thus avoiding the situation where dust and dirt adhere to the grooving position of the galvanized pipe and affect the grooving effect.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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 Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of an automatic grooving machine for galvanized pipe processing, including a work frame 1. A grooving device 3 is fixedly connected to the top wall of the work frame 1. A fixing plate 4 is fixedly connected to the front right side of the grooving device 3. The fixing plate 4 supports and fixes the electric push rod 5. The electric push rod 5 is fixedly connected to the front and rear sides of the inner wall of the fixing plate 4. A cleaning shell 6 is fixedly connected to the left end of the electric push rod 5. An installation plate 7 is fixedly connected to the inner wall of the cleaning shell 6, so that the cleaning shell 6 and the installation plate 7 move synchronously under the drive of the electric push rod 5. Bolts 8 are threaded to the front and rear ends of the right side of the installation plate 7. A cleaning brush 10 is threaded to the left end of the bolt 8, so that the cleaning brush 10 connected by the bolt 8 moves synchronously to achieve the purpose of cleaning galvanized pipes of different specifications. Under the fixed installation of the grooving device 3, the galvanized pipe rotates, so that the cleaning brush 10 completes the cleaning work of the grooving area. A collection mechanism 2 is provided on the left side of the bottom wall of the work frame 1. The collection mechanism 2 is used to collect the debris and dirt generated during the operation.

[0032] Specifically, by connecting the grooving device 3 to the galvanized pipe, but temporarily not activating the grooving function, only allowing the device to rotate, the galvanized pipe can be rotated. By activating the electric push rod 5, the left end of the electric push rod 5 drives the cleaning shell 6 to move to the left, causing the mounting plate 7 and the cleaning brush 10 fixed by the bolt 8 to move synchronously. The rotating galvanized pipe can then come into contact with the cleaning brush 10. Once the cleaning brush 10 contacts the galvanized pipe, it can begin cleaning the galvanized pipe, preventing dust and dirt from adhering to the grooving position of the galvanized pipe, thus affecting the grooving effect of the grooving device 3. In addition, when it is necessary to replace the cleaning brush 10, the operator only needs to rotate the bolt 8 to remove the cleaning brush 10 from the left side of the mounting plate 7 for replacement, which improves the flexibility of the device and effectively extends its service life.

[0033] Reference Figure 1 , Figure 2 and Figure 5The collection mechanism 2 includes an extraction fan 201. The top wall of the extraction fan 201 is fixedly connected to the left side of the bottom wall of the work frame 1. The right rear end of the extraction fan 201 is connected to an extraction pipe 202. The right end of the extraction pipe 202 is connected to a collection box 203. When the extraction fan 201 is started, the collection box 203 collects the extracted dirt through the extraction pipe 202. A sponge board 204 is fixedly connected to the rear inner wall of the collection box 203. A filter plate 205 is slidably installed on the front inner wall of the collection box 203. The filter plate 205 blocks dirt and debris. A connecting pipe 206 is connected to the front of the collection box 203. The front end of the connecting pipe 206 is connected to an extraction shell 207. The extraction shell 207 collects debris and dirt. The rear side of the extraction shell 207 is fixedly connected to the front side of the work frame 1.

[0034] Specifically, by activating the extraction fan 201, the extraction housing 207 begins to extract airflow, effectively collecting debris generated during the work process as well as dust and dirt from the cleaned galvanized pipe surface. This debris and dirt are then guided into the collection box 203 through the connecting pipe 206. The filter plate 205 intercepts and collects this debris and dirt uniformly, while the sponge plate 204 performs more detailed filtration of the airflow. Finally, the clean airflow processed by the extraction fan 201 is discharged, thereby significantly improving the cleanliness of the working environment and preventing the possibility of debris flying around in the workplace.

[0035] Reference Figure 1 , Figure 4 and Figure 5 The collection mechanism 2 also includes a rubber ring 208, the inner wall of which is fixedly installed on the rear side of the outer wall of the connecting pipe 206, and the outer wall of which is fixedly connected to the front side of the collection box 203; a control switch 12 is fixedly connected to the right side of the top wall of the work frame 1, and the control switch 12 is electrically connected to the pressing device 3, the electric push rod 5 and the extraction fan 201 respectively; a handle 16 is fixedly connected to the right side of the filter plate 205, and a rubber sleeve 17 is fixedly connected to the middle of the handle 16;

[0036] Specifically, the rubber ring 208 is used to protect the connection point of the outer wall of the connecting pipe 206 and reduce wear at the connection point. The control switch 12, which is electrically connected to the grooving device 3, the electric push rod 5 and the extraction fan 201 respectively, enables the control switch 12 to open and close the device. The rubber sleeve 17 is used to improve the protection of the handle 16.

[0037] Reference Figure 1 , Figure 2 and Figure 3A protective cover 11 is fixedly connected to the middle of the top wall of the grooving equipment 3, and support plates 13 are fixedly connected to the left and right sides of the inner top wall of the grooving equipment 3; rubber rings 9 are fixedly connected to the middle of the two bolts 8, and the two bolts 8 are symmetrically designed; two connecting seats 14 are fixedly connected to the left and right sides of the work frame 1, and support columns 15 are fixedly connected inside the connecting seats 14.

[0038] Specifically, the protective cover 11 protects the middle part of the device, the rubber ring 9 reduces the rotational damage of the bolt 8 to the mounting plate 7, and the connecting seat 14 and the support column 15 improve the lateral stability of the device during operation.

[0039] Working principle: When starting to use, the grooving device 3 is connected to the galvanized pipe but the grooving function is not activated; it is simply rotated to allow the galvanized pipe to rotate. Then, by activating the electric push rod 5, its left end drives the cleaning shell 6 to move to the left, causing the mounting plate 7 and the cleaning brush 10 fixed by the bolt 8 to move synchronously. This allows the rotating galvanized pipe to come into contact with the cleaning brush 10, and the fixed cleaning brush 10 can then clean the galvanized pipe. This prevents dust and dirt from adhering to the grooving position of the galvanized pipe and affecting the grooving effect of the grooving device 3. When replacing the cleaning brush 10, the cleaning brush 10 can be removed and replaced from the left side of the mounting plate 7 by rotating the bolt 8, which improves the flexibility of the device and extends its service life.

[0040] Furthermore, by starting the extraction fan 201, the extraction shell 207 extracts airflow, thereby collecting the debris generated during the grooving process and the dust and dirt from the cleaned galvanized pipe. The collected debris and dirt then enter the collection box 203 through the connecting pipe 206, where they are collected uniformly by the filter plate 205. After further filtration by the sponge plate 204, the extracted airflow is discharged through the extraction fan 201, thus improving the cleanliness of the working environment and preventing the possibility of debris flying around.

[0041] 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.
