Description

Technical Field

[0001] The utility model relates to the technical field of plastic forming tools, in particular to a quick plastic forming tool for the flanging of an excavator fuel tank cover. Background Technique

[0002] An excavator, also known as an earthmoving machine, is an earthmoving machine that uses a bucket to excavate materials above or below the machine's surface and load them into transport vehicles or unload them onto a stockpile. The materials excavated by the excavator are mainly soil, coal, sediment, as well as pre-loosened soil and rock. From the development of construction machinery in recent years, the development of excavators has been relatively rapid. Excavators have become one of the most important construction machinery in engineering construction. Among them, the fuel tank of the excavator is an important part of the power mechanism of the excavator;

[0003] After investigation, the publication number: CN216041444U discloses a side-turning fuel tank tool for an excavator. In this technology, it is disclosed that "a side-turning fuel tank tool for an excavator includes an L-shaped plate. A first chute is opened above the L-shaped plate, and opposite limiting grooves are opened inside the first chute. A limiting block is movably inserted inside the limiting groove. A limiting rod is fixedly connected inside the first chute. A slider and a spring sleeve are movably sleeved on the limiting rod, and the slider is fixedly connected to the limiting block. A fixing column is fixedly installed at the bottom of the slider, and the bottom end of the fixing column is fixedly connected to a clamping main board. An auxiliary clamping board is movably inserted inside the clamping main board. A cavity is opened on the front wall of the clamping main board" and other technical solutions, and has technical effects such as "it is convenient to pull the slider back to the initial position through the spring sleeve. At this time, the clamping main board and the auxiliary clamping board return to the initial position, saving manpower and increasing work efficiency. At the same time, the length of the auxiliary clamping board can be moved in position to facilitate clamping and positioning of fuel tanks of different widths";

[0004] Since the flanging and plastic forming of the fuel tank cover of the excavator mainly rely on manual operation, and this part belongs to an appearance part, two workers are required to perform plastic forming operations at the same time, resulting in a long time-consuming for a single-piece plastic forming process, seriously affecting the production progress; in addition, after the fuel tank cover part is flanged and plastically formed, its two ends are closely attached to the two ends of the reference module due to external pressure. Coupled with the relatively thin overall thickness of the fuel tank cover part, it is difficult to directly remove the part from the reference module. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides a quick plastic forming tool for the flanging of an excavator fuel tank cover, which has the characteristics that after the flanging and plastic forming of the fuel tank cover part are completed, the output end of the servo motor drives the belt pulley to drive the belt to move. The belt drives the guide frame to slide along the chute through the connecting piece and the slider. At the same time, the guide frame pushes the fuel tank cover part forward through the stripping frame to take it off from the reference module.

[0006] To achieve the above object, the utility model is realized by the following technical solutions: A quick flanging and shaping tooling for the fuel tank cover of an excavator, including a tooling platform and a fuel tank cover part.

A connecting piece is fixed on the outer wall of the belt, and a slider is rotatably mounted at the lower end of the connecting piece, and the slider is slidably mounted inside the lower end of the guide frame. A servo motor is mounted on the top of the tooling platform and is used to drive the belt wheel to rotate.

[0009] Preferably, the flanging assembly further includes support blocks fixed on both sides of the top of the tooling platform, and the inclined surfaces at the upper ends of the support blocks cooperate with the inclined surfaces at the lower ends of the shaping blocks.

[0010] Preferably, the flanging assembly further includes a second cylinder mounted at the bottom of the upper end of the reference module, and a positioning pin mounted on the output end of the second cylinder.

[0024] Please refer to Figures 1-5 , the present utility model provides a technical solution for a quick flanging and shaping tooling for an excavator fuel tank cap: A quick flanging and shaping tooling for an excavator fuel tank cap, including a tooling platform 1 and a fuel tank cap part 3, characterized in that: a tooling mechanism 2 is arranged on the tooling platform 1 and is used for flanging and shaping the fuel tank cap part 3, and the tooling mechanism 2 includes:

[0025] The flanging assembly 21 includes a reference module 211 fixed in the middle of the top of the tooling platform 1, a mounting frame 212 fixed on both sides of the top of the tooling platform 1, a first cylinder 213 installed on the upper end of the mounting frame 212, and a shaping block 214 installed on the output end of the first cylinder 213;

[0026] The stripping assembly 22 includes slide grooves 221 provided on both sides of the upper end of the tooling platform 1, a guide frame 222 slidably installed between the slide grooves 221 on both sides, a stripping frame 223 installed on the upper end of the guide frame 222, pulleys 224 rotatably installed on both sides of the front and rear sides of the lower end of the tooling platform 1, and a belt 225 is installed between the pulleys 224 on both sides, a connecting piece 226 fixed on the outer wall of the belt 225, a slider 227 rotatably installed at the lower end of the connecting piece 226, and the slider 227 is located inside the lower end of the guide frame 222 and slidably installed, and a servo motor 228 installed on the top of the tooling platform 1 is used to drive the pulley 224 to rotate.

[0027] In this embodiment, after the flanging shaping of the tank cover part 3 is completed, the pulley 224 is driven by the output end of the servo motor 228 to drive the belt 225 to move, and the belt 225 drives the guide frame 222 to slide along the slide groove 221 through the connecting piece 226 and the slider 227.
