[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] Reference Figure 1-2 This utility model provides a side punching die for a fuel tank bracket, comprising:

[0033] The mold frame includes an upper mold base 1 and a lower mold base 2, which are arranged facing each other, and a lifting component is provided between the upper mold base 1 and the lower mold base 2.

[0034] The support platform 3 is fixed at the center of the top surface of the lower mold base 2, and the cross-sectional shape of the support platform 3 matches the cross-sectional shape of the oil tank bracket.

[0035] The punching mechanism consists of two sets, which are symmetrically arranged on both sides of the support platform 3. Punches are installed on the punching mechanism, and the punches on the two punching mechanisms are coaxially arranged.

[0036] The extrusion mechanism is provided in two sets. The two sets of extrusion mechanisms are respectively installed on the bottom surface of the upper die base 1, and the two sets of extrusion mechanisms are respectively corresponding to the two sets of punching mechanisms. The two sets of extrusion mechanisms are used to push the two sets of punching mechanisms to move in opposite directions.

[0037] The positioning components are provided in two sets, and the two sets of positioning components are respectively set to correspond to the two sets of punching mechanisms.

[0038] In this invention, the mold frame consists of an upper mold base 1 and a lower mold base 2 facing each other, with relative movement between them achieved via a lifting assembly. A support platform 3 is fixed at the center of the top surface of the lower mold base 2, its cross-sectional shape matching that of the fuel tank bracket, providing stable support for the fuel tank bracket during the punching process. Two sets of punching mechanisms are symmetrically arranged on both sides of the support platform 3, each equipped with a punch, and the two punches are coaxially aligned to ensure punching accuracy and consistency. Two sets of extrusion mechanisms are respectively installed on the bottom surface of the upper mold base 1, corresponding to the punching mechanisms, and positioning components also correspond one-to-one with the punching mechanisms. The fuel tank bracket is placed on the support platform 3; since the shape of the support platform 3 matches the fuel tank bracket, it provides initial positioning, preventing movement during the punching process. The lifting assembly is activated, causing the upper mold base 1 to move downwards, bringing the extrusion mechanism closer to the punching mechanism. As the upper die holder 1 continues to descend, the extrusion mechanism drives the two sets of punching mechanisms to move in opposite directions, and the punches on the punching mechanisms punch holes on both sides of the oil tank bracket. After punching is completed, the lifting assembly drives the upper die holder 1 to rise, and the extrusion mechanism separates from the punching mechanism. At this time, the punched oil tank bracket can be removed from the support platform 3, completing one work cycle.

[0039] The scheme is further optimized. The lifting component includes hydraulic rods 4. There are two sets of hydraulic rods 4. The two sets of hydraulic rods 4 are symmetrically arranged between the upper mold base 1 and the lower mold base 2. The hydraulic rods 4 are vertically fixed to the ends of the upper mold base 1 and the lower mold base 2.

[0040] Further optimization of the scheme: the punching mechanism includes a track 5 and a slider 6. The track 5 is horizontally fixed on the lower die base 2. The slider 6 is slidably connected to the track 5. A mounting block 7 is fixedly connected to one side of the slider 6. The punch is fixedly connected to the mounting block 7. A support base 8 is fixedly connected to the lower die base 2. A guide hole is opened on the support base 8. The punch passes through the guide hole. A reset component is set between the slider 6 and the support platform 3. A sloping groove 10 is opened on the top surface of the slider 6.

[0041] The scheme is further optimized. The extrusion mechanism includes a wedge 9. The shape of the wedge 9 matches the shape of the inclined groove 10. The wedge 9 is fixedly connected to the bottom surface of the upper mold base 1 and slidably connected in the inclined groove 10. A positioning block 11 is fixedly connected to the upper mold base 1 and is correspondingly set with the slider 6.

[0042] The scheme is further optimized. The positioning component includes a positioning plate 12, which is fixedly connected to the lower mold base 2. The positioning plate 12 is located between the track 5 and the hydraulic rod 4, and the positioning plate 12 and the slider 6 are in a limiting fit.

[0043] The scheme is further optimized. The reset component includes a fixed rod 13 and a sleeve 14. The fixed rod 13 is fixed to the side of the support platform 3. The sleeve 14 is sleeved on the fixed rod 13. The sleeve 14 passes through the support base 8 and is fixed between it and the slider 6. A spring is installed inside the sleeve 14. The two ends of the spring are fixed to the fixed rod 13 and the slider 6, respectively.

[0044] The design was further optimized so that the support platform 3 was fixedly connected to the lower mold base 2 by bolts.

[0045] When this utility model is in operation, the hydraulic rod 4 is in the extended state, and a certain distance is maintained between the upper mold base 1 and the lower mold base 2. At this time, the wedge block 9 is located at a higher position in the inclined groove 10, and the slider 6 is located away from the bearing platform 3 under the action of the reset component (the spring is in the natural state). The punch is also in an unpunched state, and the positioning plate 12 and the slider 6 are in a limiting engagement state, which plays an initial positioning role for the slider 6.

[0046] The fuel tank bracket is placed on the support platform 3, which is fixed to the lower mold base 2 by bolts. Its shape matches the fuel tank bracket, and the fuel tank bracket is initially positioned.

[0047] When the hydraulic system is activated, the two symmetrically arranged hydraulic rods 4 begin to retract, causing the upper mold base 1 to move downwards. Since the hydraulic rods 4 are vertically fixed to the ends of the upper mold base 1 and the lower mold base 2, the stability and verticality of the upper mold base 1 during downward movement are ensured.

[0048] During the downward movement of the upper mold base 1, the wedge 9 fixed to the bottom surface of the upper mold base 1 slides along the inclined groove 10 on the slider 6. As the wedge 9 moves downward, due to the matching shape of the wedge 9 and the inclined groove 10, the wedge 9 will push the slider 6 to move horizontally along the track 5 towards the support platform 3.

[0049] The positioning block 11 on the upper mold base 1 moves downward with the upper mold base 1. When the positioning block 11 contacts the slider 6, it can further ensure the stability and accuracy of the slider 6's movement and prevent the slider 6 from deviating during the movement.

[0050] Slider 6 movement and punching: Slider 6 slides along track 5 under the push of wedge 9, and the punch fixed on mounting block 7 on one side of slider 6 also moves accordingly. Since support base 8 is fixedly connected to lower die base 2, and guide hole is opened on support base 8, the punch passes through the guide hole, ensuring the straightness of the punch movement. When slider 6 moves to a certain position, the punch performs a punching operation on the oil tank bracket placed on the support table 3.

[0051] During the movement of slider 6, sleeve 14 slides along fixed rod 13, and spring is compressed. The compression force of spring provides a certain buffer for the movement of slider 6. At the same time, when upper mold base 1 moves upward, the restoring force of spring will push slider 6 to reset.

[0052] After the punching operation is completed, the hydraulic system controls the hydraulic rod 4 to extend, driving the upper die holder 1 to move upward. As the upper die holder 1 moves upward, the wedge block 9 gradually slides out of the inclined groove 10, and the pushing force on the slider 6 disappears.

[0053] Under the restoring force of the spring in the reset assembly, slider 6 slides in the opposite direction along track 5, returning to its initial position. At the same time, the punch also resets with slider 6, disengaging from the oil tank bracket.

[0054] When slider 6 returns to a certain position, positioning plate 12 and slider 6 engage again to ensure that slider 6 returns to the accurate initial position, preparing for the next punching operation.

[0055] After punching is completed, the punched fuel tank bracket is removed from the support platform 3, completing one full work cycle. At this point, all parts of the mold return to their initial state, and the next punching process for the fuel tank bracket can begin.

[0056] It should be noted that the support platform 3 of this utility model is provided with through holes corresponding to the punch, so as to ensure that the punching is completed. At the same time, a material dropping hole and a coolant channel need to be provided in the middle of the support platform 3 to ensure the smooth progress of processing.

Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
