Technical Field

[0001] The utility model relates to the technical field of muffler shell processing, in particular to a muffler shell stamping and forming device. Background Art

[0002] The car muffler is a part used to reduce the noise generated by the engine of a motor vehicle.

[0003] In order to increase the distance between the muffler shell and the ground, the shells of most automobile mufflers currently adopt a flat oval structure. During production and processing, the oval structure is punched out of cut cylindrical pipes through stamping equipment. However, the existing stamping equipment requires manual loading and unloading, which is time-consuming and labor-intensive, and has a high risk factor, which can easily cause production accidents.

The motor A3 is connected to the frame 1 and drives the transmission roller on one side of the edge, wherein a plurality of groups of limit plates 201 are evenly spaced on the conveyor belt 2 to prevent the raw material pipe from rolling freely relative to the conveyor belt 2 during the transmission process following the conveyor belt 2. A movable plate 5 is arranged on the bracket 4 and is slidably connected to it, and the movable plate 5 is rotatably connected to the lower die seat 7, and a drive assembly B for driving the lower die seat 7 to rotate is arranged on the movable plate 5. The width of the lower die base 7 is greater than the width of the feeding trough, so as to improve the anti-punching ability of the lower die base 7 after both ends of the lower die base 7 fall on the frame 1. The driving assembly B includes a motor B8. A rotating shaft is set on both sides of the lower die base 7, and the rotating shaft passes through the movable plate 5 on the corresponding side and is rotatably connected thereto. The motor B8 is connected to one of the movable plates 5, and the output end of the motor B is connected to the end of one of the rotating shafts. The lifting drive includes but is not limited to a linear module 6, which is connected to the bracket 4 and drives the lower die base 7 to rise and fall. The slider 9 is slidably connected to the lower die base 7 and inserted into the mold cavity of the lower die base 7 in the horizontal direction. The bidirectional driving assembly is connected to the lower die base 7 and synchronously drives the sliders 9 on both sides. The width of the conveying trough of the bracket 1 is the same as the width of the raw material pipe and the width of the mold cavity of the lower die base 7, and the distance between the conveyor belt 2 and the upper surface of the frame 1 is less than the inner ring diameter of the raw material pipe. At the same time, when the lower die base 7 covers the raw material pipe, the sliders 9 on both sides can be inserted into the raw material pipe. The bidirectional drive assembly includes a bidirectional screw 10 and a motor C11, and the motor C11 drives and connects the bidirectional screw 10. The bidirectional screw 10 is located in the housing of the lower die base 7 and is rotatably connected thereto. The two ends of the bidirectional screw 10 are respectively spirally connected to a slide seat, and both slide seats on both sides are slidably connected to the lower die base 7, and the sliders 9 on both sides are respectively connected to the corresponding side slide seats. A motor assembly groove is set in the housing of the lower die base 7, and the motor C11 is located in the motor assembly groove.

[0025] In this embodiment, the purpose of limiting the width of the conveying trough is to prevent the raw material from being miscentered, thereby avoiding crushing the edge of the raw material pipe when the lower die seat 7 slides downward with the mold cavity opening toward the conveying trough. Under this structure, the lower die seat 7 just makes the raw material pipe inside the mold cavity during the descent process, thereby improving the accuracy of loading and unloading the raw material. During operation, first start the linear module 6 to raise the height of the lower die seat 7, then start the motor B8, the motor B8 drives the lower die seat 7 to flip until the mold cavity opening faces downward, then place the raw material pipe on the limit plate 201 on the conveyor belt 2, start the motor A3, the motor A3 drives the conveyor belt 2 to run and convey the raw material pipe to the bottom of the lower die seat 7. The positioning of the raw material pipe can be judged by the naked eye of the staff, then the linear module 6 presses down the lower die seat 7 to make the raw material pipe slide into the mold cavity, then the motor C11 drives the bidirectional screw 10 to rotate, thereby making the sliders 9 on both sides slide toward each other until they are horizontally inserted into the internal channel of the raw material pipe, then the upper The die base 7 is driven upward by the linear module 6, and the raw material pipe will also rise because it is hooked by the slider 9. Then the motor B8 drives the lower die base 7 to rotate 180 degrees so that the die cavity opening is upward, and the raw material pipe automatically falls into the die cavity. Then the linear module 6 presses down the lower die base 7 until it falls on the frame 1, and the hydraulic cylinder 13 presses down the upper die base 12 to cooperate with the lower die base 7 to punch the raw material pipe into the required shape. After the stamping is completed, the upper die base 12 slides up and resets, and the lower die base 7 first rises and then flips 180 degrees until the opening faces downward. Then the sliders 9 on both sides are synchronously moved away and reset to make the processed profile fall back on the conveyor belt 2, and the cycle is repeated.

[0026] Embodiment 2

[0027] The utility model proposes a muffler shell stamping and forming device. Compared with the first embodiment, a light transmitter and a light receiver are respectively arranged on the inner walls on both sides of the conveying trough, and a control component is arranged on the frame 1.

[0028] In this embodiment, a light signal is emitted by the light transmitter and received by the light receiver. When the raw material pipe is transported between the light transmitter and the light receiver, the light is blocked. At this time, the light receiver cannot receive the light signal, and the control component automatically controls the motor A3 to stop running. Subsequently, other electric drive structures complete the corresponding operations in sequence under the control of the control component. This process does not require manual visual judgment, thereby improving the intelligence of the device and improving work efficiency.
