Description

Technical Field

[0001] The utility model belongs to the technical field of steel member processing, and particularly relates to a processing tooling for special-shaped steel members. Background Technique

[0002] Steel members refer to steel structure composite members that can bear and transfer loads, which are formed by connecting steel plates, angle steels, channel steels, I-beams, welded or hot-rolled H-beams through cold bending or welding with connectors. They are usually used in road engineering, building engineering, etc. Before some steel members are put into use, other components need to be welded to the steel members for processing. In order to ensure the stability of the steel members during the processing, fixed tooling is generally required to fix the steel members for convenient processing.

[0003] For example, Chinese Patent Publication No.: CN220902406U, discloses a tooling for steel member welding, including a base. One side of the base is fixedly connected with a rotating frame. A support shaft is rotatably connected through the inside of the rotating frame. Two symmetrically arranged support frames are slidably sleeved on the side wall of the support shaft. A driving mechanism for driving the rotation of the support shaft is arranged on one side of the rotating frame. One side of the support frame is fixedly connected with a connecting frame, and a rotating ring is rotatably connected inside the connecting frame. The utility model is provided with structures such as support frames, connecting frames, rotating rings, cylinders, and pressing plates. Through the rotation drive of the support shaft on the support frame and the traction of the relative position movement, the positioning and fixing of the channel steel during the clamping process and the corresponding welding position in the horizontal state can be realized, so that the channel steel is always in the horizontal state during the welding process. With the rotation of the rotating ring, the convenient rotation adjustment of the welding position during the welding process of the channel steel can be realized, which is convenient for the welding process of the channel steel.

[0004] There are still deficiencies in the above application. In the above application, only one steel member can be clamped at a time. When processing multiple steel members, clamping and releasing the clamping need to be carried out one by one, and the operation is rather cumbersome and inconvenient, which affects the overall processing efficiency. At the same time, it is difficult to firmly clamp special-shaped steel members, and the applicable range is small.

[0005] Therefore, a processing tooling for special-shaped steel members is needed to solve the problems raised in the above background technique. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a processing tooling for special-shaped steel members to solve the problems raised in the above background technique.

[0007] To achieve the above object, the present utility model provides the following technical solutions: A processing tool for special-shaped steel members, including a bottom plate, on the top side surface of the bottom plate, two symmetrically distributed leg rods are fixed, and a tooling seat is jointly fixed at the tops of the two leg rods. A notch is opened on the end side surface of the tooling seat, and a plurality of notches are provided and the plurality of notches are annularly distributed. Rubber cylinders are fixed in each of the plurality of notches. A cavity is opened inside the rubber cylinder. A clamping assembly connected to the rubber cylinder is arranged at the center of the tooling seat, and a cleaning assembly is arranged on the end side surface of the tooling seat.

[0008] It should be noted in the solution that the clamping assembly includes an inner cylinder fixed at the center of the tooling seat. An external liquid cylinder communicated with the inside of the inner cylinder is fixed on the outer side wall of the inner cylinder, and a connecting pipe communicated with the inside of the inner cylinder and the rubber cylinder is fixed on the outer side wall of the inner cylinder.

[0009] It is further worth noting that a nut sleeve is fixed at one end of the external liquid cylinder away from the inner cylinder. A threaded rod is threadedly connected inside the nut sleeve. A piston member closely fitted with the inner side wall of the external liquid cylinder is fixed at one end of the threaded rod located inside the external liquid cylinder.

[0010] It is even further necessary to note that a handle rod is fixed at one end of the threaded rod located outside the external liquid cylinder, and a rubber sleeve is fitted on the side surface of the handle rod.

[0011] As a preferred implementation manner, the cleaning assembly includes an annular plate fixed on the end side surface of the tooling seat and located outside the plurality of notches. A ventilation cavity is opened inside the annular plate. Blowing holes communicated with the ventilation cavity are opened on the inner side surface of the inner ring of the annular plate. A plurality of blowing holes are provided and the plurality of blowing holes are annularly distributed. An air inlet pipe communicated with the ventilation cavity is fixed on the outer side wall of the annular plate.

[0012] As a preferred implementation manner, rubber bumps are arranged on the inner side wall of the rubber cylinder. A plurality of rubber bumps are provided and the plurality of rubber bumps are equidistantly distributed.

[0013] Compared with the prior art, the processing tool for special-shaped steel members provided by the present utility model has at least the following beneficial effects:

[0022] The following further describes the present utility model in conjunction with the embodiments.

[0023] Please refer to Figures 1-5, the utility model provides a processing tool for special-shaped steel members, including a bottom plate 7. On the top side of the bottom plate 7, two symmetrically distributed leg rods 6 are fixed. At the top of the two leg rods 6, a tooling seat 3 is jointly fixed. On the end side of the tooling seat 3, a notch 4 is opened. There are multiple notches 4, and the multiple notches 4 are annularly distributed. Rubber cylinders 5 are fixed in the multiple notches 4. A cavity is opened inside the rubber cylinder 5. At the center of the tooling seat 3, a clamping component 1 connected to the rubber cylinder 5 is arranged. On the end side of the tooling seat 3, a cleaning component 2 is arranged. When in use, multiple special-shaped steel members are respectively inserted into the rubber cylinders 5. The clamping component 1 is used to synchronously push liquid into the multiple rubber cylinders 5, so that a certain hydraulic pressure is synchronously generated inside the multiple rubber cylinders 5, causing the multiple rubber cylinders 5 to expand synchronously. Thus, the inner side walls of the rubber cylinders 5 wrap and clamp the special-shaped steel members, clamping the special-shaped steel members firmly, which is convenient for welding or installing other components on the special-shaped steel members. Multiple special-shaped steel members can be synchronously clamped and fixed at one time, effectively improving the clamping operation efficiency, thereby improving the overall processing efficiency. The contact area between the inner side wall of the rubber cylinder 5 and the surface of the special-shaped steel member is large, and the clamping stability is high. Moreover, it can adapt to steel members of different shapes for stable clamping, effectively expanding the applicable range of the overall device and increasing the overall practicality. The dust and impurities adhering to the side of the tooling seat 3 are blown and removed by the arranged cleaning component 2, cleaning the side of the tooling seat 3 and reducing the entry of dust and impurities into the rubber cylinder 5.

[0024] Further, as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown in the figure, it is worth specifically explaining that the clamping assembly 1 includes an inner cylinder 103 fixed at the center of the tooling base 3. An external liquid cylinder 101 communicating with the inside of the inner cylinder 103 is fixed on the outer side wall of the inner cylinder 103. A connecting pipe 8 communicating with the inside of the inner cylinder 103 and the rubber cylinder 5 is fixed on the outer side wall of the inner cylinder 103. A nut sleeve 105 is fixed at one end of the external liquid cylinder 101 away from the inner cylinder 103. A threaded rod 104 is threadedly connected inside the nut sleeve 105. A piston member 102 tightly fitted with the inner side wall of the external liquid cylinder 101 is fixed at one end of the threaded rod 104 located inside the external liquid cylinder 101. A certain amount of liquid is filled inside both the external liquid cylinder 101 and the inner cylinder 103. The liquid can be water or hydraulic oil, etc. During specific operation, by inserting multiple special-shaped steel members into the rubber cylinder 5 and rotating the threaded rod 104 inwardly, the threaded rod 104 drives the piston member 102 to move inside the external liquid cylinder 101. Thus, the liquid inside the external liquid cylinder 101 is squeezed into the inner cylinder 103 through the piston member 102. Then, the liquid inside the inner cylinder 103 is synchronously squeezed into multiple rubber cylinders 5 through multiple connecting pipes 8, so that a certain hydraulic pressure is synchronously generated inside multiple rubber cylinders 5, causing multiple rubber cylinders 5 to expand synchronously. Thus, the special-shaped steel members are wrapped and clamped by the inner side walls of the rubber cylinders 5, clamping the special-shaped steel members firmly, facilitating welding or installing other components on the special-shaped steel members. Multiple special-shaped steel members can be synchronously clamped and fixed at one time, effectively improving the clamping operation efficiency, thereby improving the overall processing efficiency. The contact area between the inner side wall of the rubber cylinder 5 and the surface of the special-shaped steel member is large, the clamping stability is high, and it can be used to stably clamp steel members of different shapes, effectively expanding the applicable range of the overall device and increasing the overall practicability.

[0025] Further, as shown in Figure 2 , Figure 4 and Figure 5 As shown, it is worth specifically explaining that the cleaning assembly 2 includes an annular plate 201 fixed on the side surface of the tooling base 3 and surrounding multiple notches 4. A ventilation cavity 202 is formed inside the annular plate 201. Blowing holes 203 communicating with the ventilation cavity 202 are formed on the inner side surface of the inner circle of the annular plate 201. There are multiple blowing holes 203 and the multiple blowing holes 203 are annularly distributed. An air inlet pipe 204 communicating with the ventilation cavity 202 is fixed on the outer side wall of the annular plate 201. During specific operation, the air inlet pipe 204 is externally connected to an air pump. Airflow with a certain air pressure is conveyed into the annular plate 201 through the air inlet pipe 204 and then evenly blown out through the multiple annularly distributed blowing holes 203. The dust and impurities adhering to the side surface of the tooling base 3 are blown and removed by the evenly dispersed airflow, cleaning the side surface of the tooling base 3 and reducing the entry of dust and impurities into the rubber cylinder 5.

[0026] This solution has the following working process: Insert multiple special-shaped steel members into the rubber cylinder 5 respectively. By rotating the internal threaded rod 104 inward, the threaded rod 104 drives the piston member 102 to move within the external liquid cylinder 101, thereby squeezing the liquid in the external liquid cylinder 101 into the internal cylinder 103 through the piston member 102. Then, the liquid in the internal cylinder 103 is synchronously squeezed into the multiple rubber cylinders 5 through the multiple connecting pipes 8, so that there is a certain hydraulic pressure in the multiple rubber cylinders 5 synchronously, causing the multiple rubber cylinders 5 to expand synchronously. Thus, the special-shaped steel members are wrapped and clamped by the inner side walls of the rubber cylinders 5, clamping the special-shaped steel members firmly, which is convenient for welding or installing other components on the special-shaped steel members. Airflow with a certain air pressure is conveyed into the inner part of the ring plate 201 through the air inlet pipe 204, and then evenly blown out through the multiple annularly distributed blowing holes 203. The dust and impurities adhering to the side surface of the tooling seat 3 are purged and removed by the evenly dispersed airflow, cleaning the side surface of the tooling seat 3 and reducing the entry of dust and impurities into the rubber cylinder 5.

[0027] Further, as Figure 4 shown, it is specifically noted that a handle rod 106 is fixed to the end of the threaded rod 104 located outside the external liquid cylinder 101, and a rubber sleeve is fitted and sleeved on the side surface of the handle rod 106. During specific operation, the handle rod 106 is convenient for rotating the threaded rod 104. The handle rod 106 has a longer lever arm, and the operation is labor-saving and convenient.

[0028] Further, as Figure 4 shown, it is specifically noted that rubber bumps 9 are provided on the inner side wall of the rubber cylinder 5. There are multiple rubber bumps 9, and the multiple rubber bumps 9 are equidistantly distributed. During specific operation, the multiple rubber bumps 9 effectively increase the clamping friction force of the inner side wall of the rubber cylinder 5 on the special-shaped workpiece, further improving the clamping stability.

[0029] In summary: By the pressing and clamping assembly 1, liquid is synchronously pushed into the multiple rubber cylinders 5, so that there is a certain hydraulic pressure in the multiple rubber cylinders 5 synchronously, causing the multiple rubber cylinders 5 to expand synchronously. Thus, the special-shaped steel members are wrapped and clamped by the inner side walls of the rubber cylinders 5, clamping the special-shaped steel members firmly, which is convenient for welding or installing other components on the special-shaped steel members. Multiple special-shaped steel members can be synchronously clamped and fixed at one time, effectively improving the clamping operation efficiency, thereby improving the overall processing efficiency. The contact area between the inner side wall of the rubber cylinder 5 and the surface of the special-shaped steel member is large, and the clamping stability is high. Moreover, it can be adapted to steel members of different shapes for stable clamping, effectively expanding the application range of the overall device and increasing the overall practicality. The dust and impurities adhering to the side surface of the tooling seat 3 are purged and removed by the provided cleaning assembly 2, cleaning the side surface of the tooling seat 3 and reducing the entry of dust and impurities into the rubber cylinder 5.
