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.
[0030] Reference Figure 1-4This utility model provides an embodiment of a continuous forming device for a stainless steel heat insulation cover for an automotive exhaust pipe, comprising a frame 1, a fixing plate 2 fixedly mounted on the top of the frame 1, a stamping machine body 3 fixedly mounted on the top of the fixing plate 2, a hollow groove 4 formed on the top of the fixing plate 2, a placement plate 5 disposed inside the hollow groove 4, and limiting components 6 for limiting the heat insulation cover on both sides of the top of the placement plate 5, and a resetting component 7 for resetting the placement plate 5 disposed inside the hollow groove 4. By setting the fixing plate 2, the limiting components 6 and the resetting components 7 on the frame 1 in cooperation, the limiting components 6 can effectively limit the heat insulation cover, ensuring the positional accuracy during stamping, and the resetting components 7 can realize the automatic resetting of the placement plate 5, facilitating continuous forming operations, reducing manual intervention, and improving production efficiency.
[0031] Reference Figure 1-4The limiting assembly 6 includes two sets of limiting plates 61. The limiting plates 61 and the placement plate 5 are slidably installed. Electric push rods 62 are fixedly installed on both sides of the top of the placement plate 5. The telescopic ends of the electric push rods 62 are fixedly installed on the outer side of the limiting plates 61. Square grooves 63 are opened on the front and rear sides of the top of the limiting plates 61. The limiting assembly 6 uses the slidably installed limiting plates 61 and the electric push rods 62 for driving. The position of the limiting plates 61 can be adjusted by the telescopic movement of the electric push rods 62 to adapt to the limiting requirements of heat insulation covers of different sizes and specifications, thus improving the versatility of the device. The square groove 63 on the top of the limiting plate 61 can assist in positioning with other positioning structures to further enhance the limiting effect. A square sleeve 64 is fixedly installed on the surface of the limiting plate 61. A rotating rod 65 is rotatably installed on the bottom of the inner wall of the square sleeve 64. Clamping blocks 66 are fixedly installed on the top and bottom of the surface of the rotating rod 65. The top of the rotating rod 65 extends through to the top of the square sleeve 64 and is movably installed with the square sleeve 64. The limiting plate 61 is provided with a square sleeve 64, a rotating rod 65 and clamping blocks 66. The rotating rod 65 can drive the clamping blocks 66 to rotate, so that the clamping blocks 66 can move from... The heat insulation cover is clamped and fixed at different angles, and with the limiting effect of the limiting plate 61, the stability of the heat insulation cover during the stamping process is further enhanced, preventing displacement or shaking. A motor 67 is fixedly installed on the top of the square sleeve 64, and a worm gear 68 is fixedly installed on the output end of the motor 67. A worm wheel 69 is fixedly installed on the top of the rotating rod 65. The worm gear 68 and the worm wheel 69 mesh. The motor 67 drives the worm gear 68, and the meshing of the worm gear 68 and the worm wheel 69 drives the rotating rod 65 to rotate. The rotation of the rotating rod 65 drives the clamping block 66 to rotate. The rotating clamping block 66 can limit the movement of the heat insulation cover, preventing it from loosening due to vibration during the stamping process and ensuring clamping stability. A rectangular block 8 is rotatably installed on the inner end of the worm 68. The bottom of the rectangular block 8 and the top of the square sleeve 64 are fixedly installed. The inner end of the worm 68 is rotatably connected to the top of the square sleeve 64 through the rectangular block 8. The rectangular block 8 provides a stable support point for the worm 68, effectively preventing the worm 68 from shaking or deviating during transmission, ensuring precise meshing between the worm 68 and the worm wheel 69, and improving transmission efficiency and stability.
[0032] Reference Figure 1-4The reset assembly 7 includes two sets of limiting blocks 71, which are fixedly installed on both sides of the placement plate 5. Limiting grooves 72 are formed on both sides of the inner wall of the hollow groove 4. The limiting blocks 71 and the limiting grooves 72 are slidably installed. The sliding cooperation between the limiting blocks 71 and the limiting grooves 72 in the reset assembly 7 guides the up-and-down movement of the placement plate 5, preventing lateral displacement of the placement plate 5 during reset or stamping, and ensuring the accuracy of the movement trajectory of the placement plate 5. A spring 73 is fixedly installed at the bottom of the inner wall of the limiting groove 72. The top and bottom of the limiting block 71 are fixedly installed. The spring 73 at the bottom of the limiting groove 72 is connected to the limiting block 71. After the stamping is completed, the elastic restoring force of the spring 73 can automatically drive the placement plate 5 to reset. At the same time, the spring 73 can play a buffering role during the stamping process, absorbing part of the impact force and reducing the damage to the placement plate 5 and other components caused by the stamping action. At this time, the impurities on the limiting block 71 will enter the hollow groove 4 through the slot opened at its top. Since the inside of the hollow groove 4 is inclined, the impurities can be discharged from the hollow groove 4.
[0033] Working principle: First, the heat insulation cover to be stamped can be placed on the placement plate 5. Then, according to the size and specifications of the stainless steel heat insulation cover for the automotive exhaust pipe to be processed, the electric push rod 62 is started. The extension end of the electric push rod 62 drives the limiting plate 61 to slide on the placement plate 5 until the distance between the two sets of limiting plates 61 is adapted to the width of the heat insulation cover. Then, the electric push rod 62 is turned off. Next, the motor 67 is started. The output end of the motor 67 drives the worm gear 68 to rotate. Since the worm gear 68 meshes with the worm wheel 69, the worm wheel 69 drives the rotating rod 65 to rotate in the square sleeve 64. The clamping block 66 on the surface of the rotating rod 65 rotates together until the clamping block 66 is in close contact with the surface of the heat insulation cover blank, realizing the multi-angle clamping and fixing of the blank.
[0034] Then the press body 3 is started, the press head of the press body 3 moves downward and passes through the hollow groove 4 of the fixed plate 2 to press the heat insulation cover blank on the placement plate 5. During this process, the placement plate 5 moves downward under pressure, which drives the limit blocks 71 on both sides to slide downward along the limit groove 72. The spring 73 is compressed and absorbs part of the impact force.
[0035] After stamping is completed, the stamping head of the stamping machine body 3 returns to its original position. At this time, the compressed spring 73 releases its elastic restoring force, pushing the limiting block 71 to slide upward along the limiting groove 72, which in turn drives the placement plate 5 to return to its initial position. Then, the motor 67 is started to reverse, causing the clamping block 66 to detach from the surface of the heat insulation cover. Then, the electric push rod 62 is started to drive the limiting plate 61 to move outward, releasing the limiting of the finished product and removing the formed heat insulation cover.
[0036] During this process, the impurities collected at the top slot of the limiting block 71 fall into the hollow groove 4 as the placement plate 5 moves, and are automatically discharged along the slope of the hollow groove 4, ensuring the cleanliness of the inside of the device.
[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
