Technical Field

[0001] The invention relates to the technical field of automobile lamp molding, in particular to a stamping molding device for an automobile lamp assembly. Background Art

[0002] Small metal brackets are one of the commonly used metal components in car lights. Small metal brackets are usually used to support, fix or connect car light parts to ensure the stability of the car lights when in use. Therefore, small metal brackets play an important role in the assembly and fixing process of car lights. Small metal brackets are manufactured through a stamping process, which uses stamping to ensure that the shape of the small metal bracket meets the designed size.

[0003] However, the current stamping process for small metal brackets for automobile lamps still has the following disadvantages: 1. When stamping small metal brackets, it is usually necessary to manually load and stamp them one by one, and the small metal brackets need to be taken out after stamping. The manual operation speed is limited, resulting in low production efficiency, and it is difficult to ensure that the loading position is completely consistent each time, which leads to fluctuations in product quality; 2. When stamping small metal brackets, the small metal brackets are not effectively fixed, causing the small metal brackets to shift during the stamping process, resulting in the size and shape of the finished product being different from the predetermined design, thereby affecting the stamping accuracy, and since the position of the small metal bracket may change during the stamping process, there are differences between products in batch production, affecting the consistency and reliability of the product.

[0033] See also Figure 1 The actuator 6 includes a transmission part 61 arranged on the pressing part 51 , and an actuator 62 is arranged on the transmission part 61 .

[0034] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The limiting part 41 includes a first slide rail 411, a trapezoidal slide plate 412, a stamped square hole 413, a first push plate 414, a connecting rod 415 and a first positioning roller 416. A plurality of first slide rails 411 are provided on the operating panel 3 in a linear array. The operating panel 3 is also provided with a stamped square hole 413 located between adjacent first slide rails 411. A trapezoidal slide plate 412 with a cavity inside is slidably mounted on the first slide rail 411. A connecting rod 415 slides through the rear end surface of the trapezoidal slide plate 412.

[0035] See also Figure 1 , Figure 2 and Figure 4 The driving part 42 includes a sliding hole 421, an electric push rod 422 and a connecting slider 423, wherein a sliding hole 421 penetrating the lower end surface of the operating panel 3 is opened in one of the first slide rails 411, a connecting slider 423 fixedly connected to the first push plate 414 is slidably installed in the sliding hole 421, and an electric push rod 422 fixedly connected to the connecting slider 423 at the telescopic end is fixedly installed on the lower end surface of the operating panel 3.

[0036] During specific work, before the small metal bracket needs to be stamped and formed, the telescopic end of the electric push rod 422 is in the longest telescopic state, so that the trapezoidal slide 412 is at the rear end of the first slide rail 411 at this time. During stamping, the electric push rod 422 is started to make its telescopic end move forward with the connecting slider 423. During the movement of the connecting slider 423, the first push plate 414 will be pushed forward, and the first push plate 414 will push the trapezoidal slide 412 forward through the connecting rod 415 and the rigid spring, and when the trapezoidal slide 412 is pushed to the front end of the first slide rail 411, the first slide rail 411 limits the trapezoidal slide 412, and then the electric push rod 422 stops running.

[0037] At this time, the adjacent trapezoidal slides 412 will form a space on the operating panel 3 to limit the small metal brackets, and then the small metal brackets can be placed one by one in the space through an external manipulator, and the left and right side walls of the small metal brackets can be fit with the trapezoidal slides 412, thereby completing the loading and limiting of multiple small metal brackets to ensure that each small metal bracket is stamped at the same position.

[0038] See also Figure 1 , Figure 3 and Figure 7 The lower pressing part 51 includes a hydraulic cylinder 511, a force plate 512 and a pressure plate 513. The hydraulic cylinder 511 is fixedly installed at the front end of the L-shaped support frame 2. The telescopic end of the hydraulic cylinder 511 passes through the lower wall of the front end of the L-shaped support frame 2 and is fixedly installed with the force plate 512.

[0039] See also Figure 1 and Figure 6 The adapting part 52 includes a connecting spring 521, an extrusion plate 522, a guide rod 523 and a second positioning roller 524.

[0040] See also Figure 1 , Figure 3 and Figure 5The locking portion 53 includes a locking hole 531, a second slide rail 532, an I-shaped slider 533 and a locking plug 534. Two groups of locking holes 531 are symmetrically opened on the trapezoidal slide 412. A second slide rail 532 is opened on the inner wall of the lower end of the trapezoidal slide 412. An I-shaped slider 533 located below the connecting rod 415 is slidably installed on the second slide rail 532. A sliding sleeve slidably connected to the connecting rod 415 is fixedly installed on the upper end surface of the I-shaped slider 533. A fixing plate for pushing the sliding sleeve is fixedly installed on the connecting rod 415. Locking plugs 534 corresponding to the locking holes 531 are fixedly installed on the I-shaped slider 533.

[0041] See also Figure 1 , Figure 3 and Figure 6 The matching portion 54 includes a locking rod 541 and a slot 542. The lower end surface of the extrusion plate 522 is fixedly mounted with a locking rod 541 corresponding to two adjacent groups of locking holes 531 on two adjacent trapezoidal slides 412. The locking rod 541 is provided with a slot 542 that matches the locking block 534.

[0042] During specific operation, after the limiting part 41 cooperates with the driving part 42 to complete the loading and limiting of multiple small metal brackets, the hydraulic cylinder 511 is started to press the pressing plate 513 downward through the force plate 512, and the pressing plate 513 will push the extrusion plate 522 downward through the connecting spring 521, so that the locking rod 541 at the lower end of the extrusion plate 522 is inserted into the corresponding locking hole 531, thereby squeezing and fixing the upper end surfaces of multiple small metal brackets at the same time.

[0043] Then, the electric push rod 422 is started in reverse so that it continues to push the connecting rod 415 forward through the first push plate 414 and compress the rigid spring. When the fixed disk on the connecting rod 415 contacts the sliding sleeve, the I-shaped slider 533 is pushed forward in the trapezoidal slide 412 through the cooperation of the two. Finally, the I-shaped slider 533 is inserted into the slot 542 of the locking rod 541 with the locking block 534, and the extrusion plate 522 is locked on the trapezoidal slide 412, thereby further fixing the small metal bracket and increasing the structural strength of the extrusion plate 522 during the stamping process.

[0044] See also Figure 1 , Figure 3 and Figure 7The transmission part 61 includes a bearing seat 611, a support shaft 612, a support rotating rod 613, a first punching rod 614, a second punching rod 615 and a connecting rod 616. Two left-right symmetrical bearing seats 611 are fixedly installed on the lower end surface of the operating panel 3. A support shaft 612 is installed in the bearing seat 611 through a bearing. A support rotating rod 613 is fixedly installed on the support shaft 612. A first punching rod 614 is fixedly installed between the front ends of the support rotating rods 613. Two left-right symmetrical connecting rods 616 are hinged on the first punching rod 614. A second punching rod 615 is fixedly installed between the rear ends of the support rotating rods 613. The other end of the connecting rod 616 is hinged to the force plate 512.

[0045] See also Figure 1 and Figure 7 The execution part 62 includes a first stamping roller 621 and a second stamping roller 622. The first stamping rod 614 is fixedly installed with the second stamping roller 622 corresponding to the first positioning roller 416. The second stamping rod 615 is fixedly installed with the first stamping roller 621 corresponding to the second stamping roller 622 through a support frame.

[0046] During specific operation, when the fixing mechanism 5 completes the pressing and fixing of multiple small metal brackets, the connecting spring 521 and the guide rod 523 provide sufficient downward pressing distance for the force plate 512, and the downward movement of the force plate 512 will press the first punching rod 614 downward through the connecting rod 616, so that the first punching rod 614 rotates the supporting rotating rods 613 on both sides with the supporting shaft 612 as the center point, and until the first punching rod 614 brings the second punching roller 622 to fit the front end upper surface of the small metal bracket at the same time, and the second punching rod 615 brings the first punching roller 621 to fit the rear end lower surface of the small metal bracket.

[0047] Then, the hydraulic cylinder 511 is started to make the force plate 512 continue to press the first punching rod 614 downward through the connecting rod 616, so that the second punching roller 622 punches the front end upper surface of the small metal bracket downward through the supporting rotating rod 613, and the first positioning roller 416 limits the punching arc of the small metal bracket. At the same time, the first punching roller 621 punches the rear end lower surface of the small metal bracket upward, and the second punching roller 622 limits the punching arc of the small metal bracket, thereby punching multiple small metal brackets at the same time, and the small metal brackets are punched from the original straight state to a tortuous state (such as Figure 8 A single hydraulic cylinder 511 is used to drive the fixing and stamping operations of multiple small metal brackets at the same time, thereby reducing the need for multiple independent driving devices and reducing the equipment investment cost.

[0048] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 The unloading part 43 includes a U-shaped hydraulic tube 431, a piston rod 432 and a push plate 433. A U-shaped frame is fixedly installed on the operating panel 3, and the U-shaped frame is fixedly installed on the U-shaped hydraulic tube 431. A piston rod 432 fixedly connected to the connecting slider 423 is slidably installed in the output end of the lower side of the U-shaped hydraulic tube 431.

The output end of the upper side of the U-shaped hydraulic tube 431 is fixedly connected to the push plate 433 through a piston linkage rod.

[0049] During specific operation, after the fixing and pressing mechanism 5 cooperates with the actuator 6 to complete the stamping of multiple small metal brackets, the electric push rod 422 is started in reverse to release the lock of the extrusion plate 522 through the locking part 53, and then the electric push rod 422 is stopped first, and then the hydraulic cylinder 511 is started in reverse to reset the force plate 512, and then the electric push rod 422 is started in reverse again, so that it moves the trapezoidal slide 412 backward through the driving part 42 and the limiting part 41 to release the limit on the small metal bracket, and at the same time, the connecting slider 423 moves backward to push the lower piston rod 432 into the U-shaped hydraulic tube 431, and the upper piston rod 432 pushes the push plate 433 forward through the U-shaped hydraulic tube 431. At this time, the multiple small metal brackets will be pushed out under the push of the push plate 433, and the stamping of the multiple small metal brackets is completed.

[0050] Working principle: When it is necessary to stamp and form the small metal bracket, the electric push rod 422 is started in reverse so that the telescopic end cooperates with the driving part 42 through the limiting part 41 to push the trapezoidal slide 412 to the front end of the first slide rail 411, and then the electric push rod 422 is stopped. At this time, the adjacent trapezoidal slide 412 will limit the small metal bracket on the operating panel 3, and then the small metal brackets can be placed one by one in the space through an external manipulator.

[0051] After the small metal bracket is placed, start the hydraulic cylinder 511 to push the extrusion plate 522 downward through the pressing portion 51, so that the locking rod 541 is inserted into the locking hole 531, and then continue to reversely start the electric push rod 422 to cooperate with the locking portion 53 through the limiting portion 41 to insert the locking block 534 into the slot 542 corresponding to the locking rod 541, and lock the extrusion plate 522 on the trapezoidal slide 412, thereby further fixing the small metal bracket.

[0052] Then, the hydraulic cylinder 511 is started up again, so that the extrusion plate 522 is pressed down to punch the small metal bracket through the cooperation of the transmission part 61 and the execution part 62, thereby punching a plurality of small metal brackets at the same time.

[0053] After the stamping is completed, the electric push rod 422 is started in reverse to release the lock of the extrusion plate 522 through the locking part 53, and then the electric push rod 422 is stopped first, and then the hydraulic cylinder 511 is started in reverse to reset other parts, and the electric push rod 422 is started in reverse again, so that it can move the trapezoidal slide 412 backward through the driving part 42 and the limiting part 41 to release the limit on the small metal bracket, and push out multiple small metal brackets through the unloading part 43. At this time, the stamping of multiple small metal brackets is completed.
