Description

Technical Field

[0001] This utility model relates to the field of engineering construction technology, and in particular to a modified machine for bending steel plates. Background Technology

[0002] In the construction of railways, highways, and municipal projects, further connections are needed between different components to ensure the overall quality of the structure. These connections typically utilize thicker steel plates. For example, in the construction of a highway tunnel by our company, the initial support steel arch frames were connected using drilled bolts with shims or by welding steel plates of different shapes. Drilling of the tunnel steel plates was done using a punching machine; straight steel plates were cut using a laser cutting machine, while bent steel plates were bent manually or with small tools.

[0003] Most existing technologies involve manual bending of steel plates. Manual bending is time-consuming, and the angles and curvatures of the steel plates are difficult to control, making it hard to meet design requirements. Often, individual components are not bent to the correct angles or curvatures, leading to accumulated errors during the assembly of multiple components, necessitating rework and repair. This is especially true for the initial support steel arch frame of tunnel inverts, which is often composed of standard components of varying sizes. Incorrect angles or curvatures in a single component can affect the quality and precision of the subsequent assembled product. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a modified tool for bending steel plates.

[0005] This utility model is achieved using the following technical solution: a modified tool for bending steel plates, including a base, a mold fixing block fixedly connected to the top left side of the base, a T-shaped groove opened on the inner wall of the mold fixing block, a positioning bolt slidably connected to the inner wall of the T-shaped groove, a washer contacting the outer wall of the positioning bolt, a nut threadedly connected to the outer wall of the positioning bolt, a mold contacting the top of the mold fixing block, and a punching groove opened inside the mold.

[0006] As a further improvement to the above solution, two T-shaped slides are provided, and the two T-shaped slides are symmetrically arranged around the center of the mold fixing block. Two positioning bolts are provided, and the two positioning bolts are symmetrically arranged around the center of the mold fixing block.

[0007] The above technical solution allows the nut to be unscrewed outward along the outer wall of the positioning bolt, and the nut to detach upward along the outer wall of the positioning bolt, allowing the washer to be removed upward, thereby unlocking the mold and enabling mold replacement. This facilitates the use of different molds to control the angle and curvature of the steel plate, ensuring the bending quality of steel plates at different angles.

[0008] As a further improvement to the above solution, a large arm is fixedly connected to the top right side of the base, a power distribution box is fixedly connected to the front of the large arm, a hydraulic rod fixing block is fixedly connected to the left side of the large arm, and a hydraulic rod housing is fixedly connected to the inner wall of the hydraulic rod fixing block.

[0009] As a further improvement to the above solution, a hydraulic rod piston is slidably connected to the inner wall of the hydraulic rod housing, and a fixing block is fixedly connected to the outer wall of the hydraulic rod housing, with a threaded hole on the inner wall of the fixing block.

[0010] As a further improvement to the above solution, two fixing blocks are provided, and the two fixing blocks are symmetrically arranged around the center of the hydraulic rod housing. Two threaded holes are provided, and the two threaded holes are symmetrically arranged around the center of the hydraulic rod housing.

[0011] As a further improvement to the above solution, a second threaded hole is provided at the bottom of the inner wall of the hydraulic rod piston, and the top of the punch is threadedly connected to the inner wall of the second threaded hole.

[0012] As a further improvement to the above solution, a punch sleeve is threadedly connected to the bottom of the outer wall of the punch top, and a stamping module is disposed in contact with the inner wall of the punch sleeve.

[0013] With the above technical solution, when different stamping modules need to be replaced after changing different molds, the punch sleeve is rotated outward to disengage from the bottom thread of the punch tip. Then, the punch sleeve and stamping module are replaced together, thereby enabling the processing of steel at different angles, reducing angle deviation and ensuring the bending quality of the steel plate. Furthermore, the mold can be replaced with a punching mold, and the stamping module can be replaced with a punching part. The steel disengagement device is fixed to the threaded hole opened in the inner wall of the fixing block by bolts to realize the punching of steel, making the equipment versatile.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention allows the mold to be unlocked by unscrewing the nut outward along the outer wall of the positioning bolt, and the nut disengaging upward along the outer wall of the positioning bolt, allowing the washer to be removed upward. This enables mold replacement, facilitating the use of different molds and ensuring the bending quality of steel plates at different angles.

[0016] This invention allows for the processing of steel at different angles when different stamping modules need to be replaced after changing different molds. By rotating the punch sleeve outwards, the punch sleeve disengages from the threaded bottom of the punch tip. Then, the punch sleeve and stamping module are replaced together. This reduces angular deviation and ensures the bending quality of the steel plate. Furthermore, the mold can be replaced with a punching mold, and the stamping module can be replaced with a punching part. The steel disengagement device is fixed to the threaded hole in the inner wall of the fixing block with bolts, enabling punching of steel and making the equipment versatile.

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0027] Example:

[0028] Please combine Figure 1-7 This embodiment of a modified tool for bending steel plates includes a base 1, a mold fixing block 2 fixedly connected to the top left side of the base 1, a T-shaped groove 3 opened on the inner wall of the mold fixing block 2, a positioning bolt 4 slidably connected to the inner wall of the T-shaped groove 3, a washer 5 contacting the outer wall of the positioning bolt 4, a nut 6 threadedly connected to the outer wall of the positioning bolt 4, a mold 7 contacting the top of the mold fixing block 2, and a punching groove 8 opened in the mold 7.

[0029] Two T-shaped slides 3 are provided, and the two T-shaped slides 3 are symmetrically arranged around the center of the mold fixing block 2. Two positioning bolts 4 are provided, and the two positioning bolts 4 are symmetrically arranged around the center of the mold fixing block 2.

[0030] The top right side of the base 1 is fixedly connected to the boom 9, the front of the boom 9 is fixedly connected to the distribution box 10, the left side of the boom 9 is fixedly connected to the hydraulic rod fixing block 11, and the inner wall of the hydraulic rod fixing block 11 is fixedly connected to the hydraulic rod housing 12.

[0031] A hydraulic rod piston 13 is slidably connected to the inner wall of the hydraulic rod housing 12, and a fixing block 14 is fixedly connected to the outer wall of the hydraulic rod housing 12. A threaded hole 15 is opened on the inner wall of the fixing block 14.

[0032] There are two fixing blocks 14, which are symmetrically arranged around the center of the hydraulic rod housing 12. There are two threaded holes 15, which are symmetrically arranged around the center of the hydraulic rod housing 12.

[0033] The bottom of the inner wall of the hydraulic rod piston 13 is provided with a threaded hole 16, and the inner wall of the threaded hole 16 is threaded with the top of the punch 17.

[0034] The bottom of the outer wall of the punch tip 17 is threaded with a punch sleeve 18, and the inner wall of the punch sleeve 18 is in contact with a stamping module 19.

[0035] The implementation principle of a modified tool for bending steel plates in this embodiment is as follows: Nut 6 can be unscrewed outwards along the outer wall of positioning bolt 4, causing nut 6 to disengage upwards along the outer wall of positioning bolt 4. Washer 5 can then be removed upwards along the outer wall of positioning bolt 4, thereby unlocking mold 7 and enabling its replacement. This facilitates the use of different molds to control the angle and curvature of the steel plate, ensuring the bending quality. When different molds 7 require different stamping modules 19, the punch sleeve 18 is rotated outwards to disengage from the bottom thread of the punch tip 17. Then, the punch sleeve 18 and stamping module 19 are replaced together, thus enabling the processing of steel at different angles, reducing angle deviations, and ensuring the bending quality of the steel plate. The replacement of mold 7 and stamping module 19... After completion, the steel is placed directly above the mold 7, and then the hydraulic rod piston 13 is operated. The hydraulic rod piston 13 pushes the punch tip 17 downward, the punch tip 17 pushes the punch sleeve 18, the punch sleeve 18 pushes the stamping module 19, and the stamping module 19 moves downward to bend the unprocessed steel along the curvature of the mold 7 surface. After stamping is completed, the hydraulic rod piston 13 moves upward to make the stamping module 19 detach from the steel surface. The pressed steel plate has a beautiful shape and the angle and curvature meet the design requirements. Moreover, it is simple to manufacture and has high construction efficiency. Furthermore, the mold 7 can be replaced with a punching mold, and the stamping module 19 can be replaced with a punching part. The steel detachment device is fixed inside the threaded hole 15 opened in the inner wall of the fixing block 14 by bolts to realize the punching of steel, making the equipment versatile.
