Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings.

[0021] according to Figures 1-4 As shown: This utility model provides a forming machine for processing bicycle mudguards: including a base 1, with a support frame 2 fixedly connected upward to the base 1; a worktable 10 is fixedly installed on the base 1, and a forming groove 11 is opened in the worktable 10; a working hydraulic cylinder 6 is installed in the support frame 2, and a forming punch 14 driven by the working hydraulic cylinder 6 is installed in the support frame 2, the forming punch 14 being positioned corresponding to the forming groove 11; a sliding plate 5 is fixedly connected to the working end of the working hydraulic cylinder 6, and a pressure plate 3 is connected below the sliding plate 5 through a sliding elastic structure; the forming punch 14 is fixedly installed below the pressure plate 3, and a pressure monitoring component corresponding to the sliding elastic structure is installed on the pressure plate 3; a controller 13 is installed on the outer wall of the support frame 2, and the controller 13 is electrically connected to the pressure monitoring component and the working hydraulic cylinder 6; a cutting groove 19 is opened in the worktable 10 on both sides of the forming groove 11, and a sliding groove 17 is opened in the pressure plate 3, with a cutting component corresponding to the cutting groove 19 slidably installed in the sliding groove 17.

[0022] By setting a cutting component inside the molding equipment, the bicycle mudguard can be directly cut after molding by using the working hydraulic cylinder 6 to clamp and fix it. This is quick and convenient, greatly improving work efficiency, and there is no need to worry about the mudguard deforming during the clamping and cutting process.

[0023] like Figure 1 , 2 As shown, the sliding elastic structure includes a fixed rod 4 and a spring 8. The fixed rod 4 is fixedly mounted on the pressure plate 3, and the sliding plate 5 is slidably sleeved on the fixed rod 4. The spring 8 is located between the sliding plate 5 and the pressure plate 3, and is sleeved on the fixed rod 4. A limit block 7 is provided above the sliding plate 5, and the limit block 7 is fixedly connected to the upper end of the fixed rod 4. The limit block 7 prevents the sliding plate 5 from detaching from the fixed rod 4.

[0024] The pressure monitoring component includes a pressure sensor 9, which is located on the pressure plate 3. The pressure sensor 9 corresponds to the position of the spring 8 and is electrically connected to the controller 13. When the sliding plate 5 slides relative to the fixed rod 4, it can compress the spring 8 and cause deformation. The pressure sensed by the pressure sensor 9 will also change, thus achieving the effect of pressure monitoring.

[0025] like Figure 3 As shown, the cutting assembly includes a support plate 16 and a cutting blade 18. The support plate 16 is slidably disposed within a groove 17. The cutting blade 18 is fixedly disposed below the support plate 16. There are two cutting blades 18, and their positions correspond to those of the cutting groove 19. A cutting hydraulic cylinder 15 is disposed on the pressure plate 3, and the working end of the cutting hydraulic cylinder 15 is fixedly connected to the support plate 16. A groove 12 corresponding to the cutting hydraulic cylinder 15 is provided at the bottom of the sliding plate 5. The cutting hydraulic cylinder 15 can drive the support plate 16 and the cutting blade 18 downward to move them out of the groove 17, thereby cutting the mudguard. At the same time, the groove 12 can prevent interference and collision between the sliding plate 5 and the cutting hydraulic cylinder 15 when the sliding plate 5 moves downward.

[0026] The workbench 10 has drainage channels 20 on both sides that are connected to the cutting groove 19 to facilitate the discharge of waste materials.

[0027] The principle of this utility model

[0028] like Figures 1-2 As shown, when forming a bicycle mudguard, the raw material to be formed is placed on the worktable 10. First, the working hydraulic cylinder 6 is activated, driving the sliding plate 5 and the pressure plate 3 to move downwards, so that the forming punch 14 and the forming groove 11 press and form the raw material. As the pressure plate 3 moves downwards, it is resisted by the raw material, and the displacement of the pressure plate 3 gradually decreases or even stops, while the sliding plate 5 continues to move downwards. The sliding plate 5 slides and compresses the spring 8 relative to the fixed rod 4. The pressure sensor 9 transmits the sensed pressure to the controller 13. When the set value is reached, the controller 13 controls the working hydraulic cylinder 6 to stop, thereby ensuring the controllability of the pressing force and improving the product pressing quality.

[0029] After pressing and forming, keep the working hydraulic cylinder 6 stationary and start the cutting hydraulic cylinder 15. Driven by the cutting hydraulic cylinder 15, the support plate 16 and the cutting blade 18 move downward to cut off the edge above the cutting groove 19, thus quickly completing the edge trimming work. The waste material that falls off during cutting falls into the cutting groove 19 and can be easily removed from the drainage channel 20. After forming and edge trimming are completed, start the working hydraulic cylinder 6 to disengage the forming punch 14 from the forming groove 11.

[0030] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
