Description

Technical Field

[0001] The present invention relates to the technical field of large presses, and particularly to a support tool for passing a tie rod through a column of a large press. Background Art

[0002] During the operation of a large press, the tie rod and the column play crucial roles. The tie rod is responsible for transmitting pressure and ensuring the stability of the press structure, while the column undertakes the functions of supporting the press structure, guiding and positioning, and dispersing pressure. However, during the installation, commissioning, and maintenance of a large press, there are many challenges in the precise installation and stress protection of the tie rod.

[0003] Currently, for the positioning and support of a large press during installation, traditional methods have many deficiencies. On the one hand, there is a lack of an effective auxiliary support device. When installing the tie rod, it is difficult to accurately pass through the column hole, and it is difficult to fix the exposed upper end of the tie rod. The installation efficiency is low and position deviation is likely to occur, affecting the overall performance of the press. On the other hand, during the operation of the press, the existing support methods cannot fully guarantee the stability of the tie rod. The tie rod is prone to displacement or damage due to uneven stress, shaking and other factors, thereby affecting the normal operation of the press and the product quality.

[0004] In view of this, the present invention is specifically proposed to solve the above technical problems. Summary of the Invention

[0005] The purpose of the present invention is to provide a support tool for passing a tie rod through a column of a large press to solve the technical problem of low installation efficiency of the column and tie rod during the installation of the existing large press.

[0006] The purpose of the present invention is to provide a support tool for passing a tie rod through a column of a large press, which includes a support structure arranged at the upper end of the column. The support structure includes a bottom plate arranged at the upper end of the column. Two round holes corresponding to the tie rod are opened on the bottom plate, and support pipes are communicated with the round holes. The lower end of the tie rod sequentially passes through the support pipe, the round hole and the column, and the upper end of the tie rod passes through the upper end of the support pipe.

[0007] Furthermore, a rib plate is connected between the upper and lower ends of the two support pipes, and a lifting hole is opened on the rib plate.

[0008] Furthermore, two reinforcing rib plates are symmetrically arranged on the peripheral wall of the support pipe. The lower end of the reinforcing rib plate is fixedly connected with the bottom plate, and the reinforcing rib plate is perpendicular to the vertical plane of the rib plate.

[0009] Furthermore, positioning grooves are opened on both sides of the upper end surface of the column, and positioning parts matched with the positioning grooves are arranged on both sides of the bottom of the bottom plate. When the bottom plate is buckled on the top plate of the column, the positioning parts are located in the positioning grooves.

[0010] Furthermore, the positioning part includes two parallel convex strips, and the two convex strips are respectively abutted against the two side walls of the corresponding positioning groove.

[0011] Further, a plurality of connection holes are formed in the bottom plate, and fastening screws are arranged in the connection holes. The lower end of the fastening screw is threadedly connected to the upper end surface of the column.

[0012] Furthermore, a rubber pad is arranged on the inner wall of the upper end of the support pipe, and the rubber pad is sleeved on the pull rod.

[0013] By adopting the above technical solutions, the present invention has the following beneficial effects: 1. During the installation process of the pull rod of the large press, the support pipe provides reliable support guidance and support height for it. This guiding function not only ensures the stability of the pull rod during the installation process, but also greatly simplifies the assembly operation process. With the help of the support pipe, the pull rod can pass through the hole position of the column more smoothly, significantly reducing the installation difficulty and effectively shortening the installation cycle.

[0014] 2. The support pipe can accurately ensure the alignment accuracy between the pull rod and the column, effectively preventing the pull rod from shifting during the installation process. This precise positioning provides a stable and accurate benchmark for the subsequent assembly work, which is of great significance for ensuring the accuracy of the overall structure of the large press.

[0015] 3. Through the provided support structure, during the installation process of the pull rod, the support structure can effectively bear the pressure and bending force generated by the pull rod, evenly disperse the stress generated during the installation process, make the pull rod more evenly stressed during installation, and avoid the problem of column deformation that may be caused by uneven stress. This not only helps to improve the overall performance of the large press, but also plays a crucial role in improving the quality of the pressed products. Description of the Drawings

Detailed Description of the Specific Embodiment

[0019] The specific embodiment of the present invention will be further described in detail in conjunction with the accompanying drawings.

[0020] See Figures 1 to 4 As shown, the embodiment of the present application provides a support tool for a large press column to pass through a tie rod, including a support structure 3 arranged at the upper end of the column 1. The support structure 3 includes a bottom plate 31 arranged at the upper end of the column 1. Two round holes 38 corresponding to the tie rod 2 are formed in the bottom plate 31. Support pipes 32 are communicated with the round holes 38. The height dimension of the support pipes 32 is determined according to the installation process dimension. The lower end of the tie rod 2 sequentially passes through the support pipes 32, the round holes 38 and the column 1. The upper end of the tie rod 2 passes through the upper end of the support pipe 32. A flange 33 is connected to the upper end of the support pipe 32. A fixed bushing 4 is connected to the flange 33. The fixed bushing 4 is of an annular structure. By connecting the flange 33 with the bushing 4, the whole support structure 3 is convenient to be installed on the upper crossbeam of the large press. A plurality of positioning holes are formed in the peripheral wall of the bushing 4. Positioning bolts are screwed in the positioning holes. The positioning bolts are used to position the tie rod 2. The upper end of the fixed bushing 4 is fixedly connected to the upper crossbeam of the press.

[0021] It should be noted that the size of the bottom plate 31 is designed according to the size of the column 1. When the large press is working, the huge load transmitted by the tie rod 2 will act concentratedly on a local area of the column 1 of the large press. The support structure 3 can evenly disperse the pressure of the tie rod 2 onto a larger area of the column 1 of the large press, avoiding excessive local stress on the column 1 that may cause extrusion damage, maintaining the overall stability of the large press, thus ensuring the machining accuracy and die life of the press, and extending the service life of the column 1. During the maintenance process of the large press, the support structure 3 can provide a stable lifting platform for the inspection and repair of the tie rod 2, facilitating the operation of technicians, shortening the maintenance time, and improving the availability of the equipment. During the process of the tie rod 2 passing through the column 1, the support structure 3 provides stable support for the penetration of the tie rod 2, keeping the tie rod 2 in the correct position and angle, facilitating the penetration operation, and improving the installation efficiency of the tie rod 2. During the disassembly process of the tie rod 2, the support structure 3 can also bear part of the weight of the tie rod 2, facilitating the disassembly operation. During the installation stage, the support structure 3 can flexibly adjust the position and height of the tie rod 2, helping the staff quickly find the optimal working parameters and installation positions. The main function of the tie rod 2 is to transmit the huge pressure generated by the large press to the die or workpiece, causing plastic deformation of the workpiece or die. By using tie rods 2 of different lengths, the closing height between the upper and lower dies of the large press can be changed, enabling the large press to adapt to the processing requirements of workpieces with different thicknesses and the installation requirements of different dies. The column 1 is an important support component of the large press, vertically installed on the installation foundation of the large press, bearing the weight of the upper and lower crossbeams of the large press. During the working process of the large press, the column 1 bears the huge pressure transmitted by the tie rod 2 and the gravity of the structure of the large press itself, ensuring the stable installation of the entire press on the working site. When the tie rod 2 transmits pressure for pressing work, the column 1 disperses the concentrated pressure onto the installation foundation of the large press, making the pressure evenly distributed over a larger area, avoiding damage to the installation foundation of the large press due to excessive local pressure, and also helping to reduce the vibration and noise generated during the operation of the large press, ensuring the stability of the working environment of the large press.

[0022] When installing the fixed bushing 4, the fixed bushing 4 is fixed to the flange 33 by bolts. After adjusting the position of the upper end of the tie rod 2 inside the support tube 32, by tightening the positioning bolts, the positioning bolts fix the position of the tie rod 2 inside the support tube 32. If the horizontal accuracy of the tie rod 2 inside the support tube 32 needs to be adjusted, the horizontal accuracy of the tie rod 2 can be adjusted by adjusting multiple positioning bolts.

[0023] In the above solution, by providing the support tube 32, when installing the tie rod 2, it provides support and guidance for the installation of the tie rod 2, and can also ensure the stability of the tie rod 2, simplify the assembly operation, reduce the installation difficulty of the tie rod 2, shorten the installation cycle, enable the tie rod 2 to quickly pass through the hole position of the column 1, ensure the alignment accuracy between the tie rod 2 and the column 1, prevent deviation, provide a reference for subsequent assembly, guarantee the accuracy of the overall structure of the large press, and by providing the support structure 3 and installing the support tube 32 on the bottom plate 31, the support structure 3 bears the pressure and bending force during the installation of the tie rod 2, disperses the stress during the installation process, so that the tie rod 2 is evenly stressed, avoids deformation of the column 1 due to uneven stress, and thus improves the quality of the products pressed by the large press.

[0024] In some possible implementation solutions, as shown in Figure 2 As shown, a rib plate 35 is connected between the upper and lower ends of the two support tubes 32. A lifting hole is provided on the rib plate 35. Since the overall structure and mass of the support structure 3 are relatively large, when installing the support structure 3, a lifting tool is required for hoisting. By providing the rib plate 35 with a lifting hole, it is convenient to lift the entire support structure 3.

[0025] In some possible implementation solutions, as shown in Figure 2 and Figure 3 As shown, two reinforcing rib plates 34 are symmetrically arranged on the peripheral wall of the support tube 32. The lower ends of the reinforcing rib plates 34 are fixedly connected to the bottom plate 31. The reinforcing rib plates 34 are perpendicular to the vertical plane of the rib plate 35. The reinforcing rib plates 34 are used to improve the structural stability of the support tube 32, prevent the support tube 32 from bending under stress, and the two support tubes 32 are connected by the rib plate 35, which can further improve the structural stability of the support tube 32.

[0026] In some possible implementation solutions, as shown in Figures 2 to 4 As shown, positioning grooves are provided on both sides of the upper end face of the column 1, and positioning members 36 that cooperate with the positioning grooves are provided on both sides of the bottom of the bottom plate 31. When the bottom plate 31 is buckled on the column 1, the positioning members 36 are located in the positioning grooves. The positioning member 36 includes two parallel convex strips, and the two convex strips are respectively abutted against the two side walls of the corresponding positioning groove. A plurality of connection holes 37 are provided on the bottom plate 31, and fastening screws are arranged in the connection holes 37. The lower ends of the fastening screws are threadedly connected to the upper end face of the column 1.

[0027] In the above solution, when the bottom plate 31 is installed in cooperation with the column 1, the ridges at the bottom of the bottom plate 31 are located in the corresponding positioning grooves, and the two ridges on the same side are respectively abutted against the two side walls of the positioning groove, and the ridges are fixed to the inner wall of the positioning groove by welding to limit the bottom plate 31 in the horizontal direction, and then the bottom plate 31 and the column 1 are fixedly connected by fastening screws, so that the support structure 3, the column 1 and the tie rod 2 form an integral body, improving the stability of the column 1 structure and facilitating hoisting and installation.

[0028] In some possible implementation schemes, a rubber pad is provided on the inner wall of the upper end of the support pipe 32, the rubber pad is sleeved on the tie rod 2, and the rubber pad is used to protect the tie rod 2 and limit its shaking to prevent friction between the tie rod 2 and the support pipe 32.

[0029] This specific embodiment is only an explanation of the invention, and it is not a limitation of the invention. After reading this specification, those skilled in the art can make modifications to this embodiment that do not contribute creatively according to needs, but as long as they are within the protection scope of the invention, they are protected by the patent law.
