Description

Technical Field

[0001] This utility model relates to the field of welding pretreatment tooling technology, and in particular to a beveling and fixing device for pipe end plates. Background Technology

[0002] A bevel is a sloping notch pre-machined at the welding end of pipe fittings, plates, etc. This structure provides sufficient operating space for welding, ensuring the depth of weld penetration and avoiding defects such as incomplete penetration or slag inclusions. The bevel of the end plate of a pipe fitting is a special structure designed to facilitate welding, and its core function is to optimize the welding process and improve the connection quality.

[0003] Currently, beveling is generally performed manually, but existing technology has the following problems:

[0004] 1. Low processing efficiency. Although manual cutting equipment is simple and adaptable, the surface quality of the bevel is poor, requiring a lot of grinding and cleaning work afterward. The actual overall efficiency is not ideal. For large-diameter, thick-walled pipes, traditional mechanical beveling may take several hours to complete one bevel, which seriously restricts the overall production efficiency and leads to low processing efficiency.

[0005] 2. Difficulty in controlling processing precision. Traditional beveling machines suffer from insufficient overall rigidity due to the separate design of the pipe conveying, support logistics, and machine base. This results in low concentricity with the beveling disc, making it difficult to guarantee the perpendicularity of the pipe end face to the machine. Furthermore, manual operation heavily relies on worker experience, easily leading to problems such as uneven beveling angles and jagged cuts, making it difficult to achieve uniform and precise processing. This directly affects the quality of subsequent welding.

[0006] 3. Insufficient mechanization. Current manual processing methods have a low level of mechanization, resulting in high labor intensity for workers and difficulty in guaranteeing processing quality.

[0007] Therefore, in view of the shortcomings of the above-mentioned solutions in actual production and implementation, modifications and improvements have been made. At the same time, in the spirit and concept of seeking excellence, and with the assistance of professional knowledge and experience, and after much ingenuity and experimentation, a beveling and fixing device for pipe end plates is specially provided to solve the technical problems of low efficiency, poor accuracy and mechanization in current beveling processes. Utility Model Content

[0008] The purpose of this utility model is to provide a beveling and fixing device for pipe end plates, which solves the technical problems of low efficiency, poor precision and low level of mechanization in current beveling processes.

[0009] The technical solution of this utility model is implemented as follows:

[0010] A beveling and fixing device for pipe end plates includes a base plate, a wedge block, and a compensation block. The base plate has two parallel side plates, and a front blocking plate and a tail blocking block are respectively provided at the left and right ends between the two side plates. The front blocking plate, the tail blocking block, the base plate, and the two side plates cooperate to form a placement space for placing the end plate. A longitudinal rod is provided in the placement space. The longitudinal rod passes through the wedge block and the wedge block is slidably connected to the longitudinal rod. A positioning nut that cooperates with the longitudinal rod is provided on the top of the wedge block.

[0011] The front end of the wedge is in contact with the inner side of the front blocking plate, and the rear end of the wedge is in contact with the front end of the compensation block. The rear end of the compensation block is provided with a first inclined surface, and the front end of the tail blocking block is provided with a second inclined surface that matches the first inclined surface. When the front end of the compensation block is in close contact with the wedge, the inclination of the second inclined surface is the same as that of the first inclined surface.

[0012] In a preferred embodiment, the bottom of the front blocking plate is fixed to the base plate, and the left and right sides of the front blocking plate are fixedly connected to two side plates.

[0013] The tail plug has bolt holes at the top, and the tail plug is detachably fixed to the base plate by bolts.

[0014] In a preferred embodiment, the top of the wedge is flat, and when the front end of the compensation block is in close contact with the wedge, the top of the compensation block is flush with the wedge.

[0015] The beneficial effects of this utility model are:

[0016] This solution is a device for auxiliary fixing of pipe fitting end plates. By using this solution with a grinding machine to batch grind the pipe fitting end plates located in the placement space, batch beveling can be achieved, replacing manual beveling. Since multiple pipe fitting end plates are processed at one time using a mechanized method, the processing efficiency is higher and the processing accuracy is more guaranteed. It reduces labor intensity, improves the quality of beveling, and effectively solves the technical problems of low efficiency, poor accuracy and mechanization in current beveling processing.

[0028] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0029] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0030] In the description of the embodiments, unless otherwise expressly specified and limited, the terms "set," "connect," etc., should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or a connection through an intermediate medium, or it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] like Figures 1-3 As shown, a bevel 15 processing and fixing device for pipe end plates includes a base plate 5, a wedge block 2 and a compensation block 3. Two parallel side plates 6 are provided on the base plate 5. A front blocking plate 1 and a tail blocking block 4 are respectively provided at the left and right ends between the two side plates 6. The front blocking plate 1, the tail blocking block 4, the base plate 5 and the two side plates 6 cooperate to form a placement space 7 for placing the end plate. A longitudinal rod 11 is provided in the placement space 7. The longitudinal rod 11 passes through the wedge block 2 and the wedge block 2 is slidably connected to the longitudinal rod 11. A positioning nut 9 that cooperates with the longitudinal rod 11 is provided on the top of the wedge block 2.

[0032] The front end of the wedge block 2 is in contact with the inner side of the front blocking plate 1, and the rear end of the wedge block 2 is in contact with the front end of the compensation block 3. The rear end of the compensation block 3 is provided with a first inclined surface 10, and the front end of the tail blocking block 4 is provided with a second inclined surface 8 that matches the first inclined surface 10. When the front end of the compensation block 3 is in close contact with the wedge block 2, the inclination of the second inclined surface 8 is the same as that of the first inclined surface 10.

[0033] The bottom of the front blocking plate 1 is fixed to the base plate 5, and the left and right sides of the front blocking plate 1 are fixedly connected to the two side plates 6.

[0034] The tail block 4 has bolt holes at the top and is detachably fixed to the base plate 5 by bolts.

[0035] The top of wedge 2 is flat, and when the front end of compensation block 3 is close to wedge 2, the top of compensation block 3 is flush with wedge 2.

[0036] See Figure 4 , Figure 5 , Figure 8 This is a schematic diagram of the usage state of this solution, so as to help understand the processing process and the relative positional relationship during processing in conjunction with the end plate 12 of the pipe fitting to be processed;
