DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] Embodiment 1:

[0026] See also Figure 1 A block-type automobile flanging shaping mold includes: a base 1, a frame 3, a lower mold 2, an upper mold 4 and a hydraulic push rod. The frame 3 is installed on the top wall of the base 1, the hydraulic push rod is installed on the top wall of the frame 3, the moving end of the hydraulic push rod extends into the inner cavity of the frame 3 and is connected to the upper mold 4, the lower mold 2 is installed on the top wall of the base 1, the lower mold 2 is inside the frame 3, the lower mold 2 and the upper mold 4 are both block-type molds, and the block-type mold belongs to the existing equipment, which will not be described in detail here;

[0027] See also Figure 1 and Figure 3 In order to prevent the ends of the processed material from warping during processing, a limit mechanism 5 is installed on the inner walls of the left and right sides of the frame 3 ( Figure 1The limiting mechanism 5 includes a mounting block 51 and a limiting block 52. The mounting block 51 is mounted on the inner side wall of the frame 3. A placement groove 56 is provided on one side wall where the mounting blocks 51 on the left and right sides are close to each other. The placement groove 56 is arranged horizontally. The limiting block 52 is inserted into the inner cavity of the placement groove 56 for sliding. The limiting block 52 can move left and right in the inner cavity of the placement groove 56. When the processed material is placed on the lower die 2, the two limiting blocks 52 are respectively in contact with the upper surfaces at both ends of the processed material to press the two ends of the processed material to prevent the ends of the processed material from being greatly tilted during processing. When the upper die 4 squeezes the processed material into the groove of the lower die 2, the two ends of the processed material will move toward the middle and get closer. At this time, the limiting blocks 52 will also move to ensure that the limiting blocks 52 press the two ends of the processed material.

[0028] See also Figure 1 , Figure 2 and Figure 3 A mounting plate 53 is mounted on the inner end of the mounting block 51 (the mounting plate 53 is mounted on a side wall of the left and right mounting blocks 51 that are away from each other), a slider 531 is mounted on a side wall of the mounting plate 53 that is away from the mounting block 51, a longitudinal slide groove 6 is provided at the connection portion between the frame 3 and the mounting block 51, the slider 531 is slidably inserted into the inner cavity of the slide groove 6, the slider 531 can move up and down in the inner cavity of the slide groove 6, an elastic member 7 (the elastic member 7 refers to a spring) is mounted between the outer wall of the slider 531 and the inner wall of the slide groove 6, and the two ends of the processed material will be tilted upward when being processed, which will raise the limit block 52 Provide an upward extrusion force, and as the extrusion amplitude of the processed material increases, the amplitude of the upward warping of the two ends of the processed material will also increase, so that the upward force on the limit block 52 will also increase, and thus the force on the two ends of the processed material will also increase (which may easily cause the processed material to bulge in the area close to the limit block 52, affecting the processing quality of automobile parts), and the slider 531 will slide upward in the inner cavity of the slide groove 6, so that the mounting block 51 and the limit block 52 move upward, reducing the contact pressure between the limit block 52 and the end of the processed material, and avoiding the bulging of the processed material;

[0029] See also Figure 3 and Figure 4In order to prevent the limiting mechanism 5 from affecting the two ends of the upper mold 4 pressing the processing material, a mounting seat 54 is installed on the upper surface of the outer end of the limiting block 52, and a mounting groove 542 is provided on the top wall of the mounting seat 54. A pressing block 55 is slidably inserted into the inner cavity of the mounting groove 542. The pressing block 55 can slide up and down, and the top of the pressing block 55 is located on the top outer side of the mounting seat 54. An elastic element 544 (spring) is installed between the bottom outer wall of the pressing block 55 and the bottom of the inner cavity of the mounting groove 542 to provide a downward pulling force to the pressing block 55. A touch switch 543 is installed at the bottom of the inner cavity of the mounting groove 542. A groove is provided on the top wall of the pressing block 55, and a slot is provided at the bottom of the inner cavity of the groove. A support block 541 is installed on the top wall of the mounting seat 54. The support block 541 is L-shaped. An insert block is installed on the inner wall of the top, and the insert block is inserted into the inner cavity of the slot. The friction between the outer wall of the insert block and the inner wall of the slot fixes the pressure block 55, so that the pressure block 55 does not automatically move down. In order to control the limit block 52 to automatically retract into the inner cavity of the placement slot 56, a first magnetic block 57 is installed on the inner end face of the limit block 52, and an electromagnet 58 is installed in the inner cavity of the placement slot 56. The electromagnet 58 is opposite to the first magnetic block 57, and the magnetic poles of the electromagnet 58 and the first magnetic block 57 on the side close to each other are opposite. When the electromagnet 58 is energized, suction is generated between it and the first magnetic block 57, so that the limit block 52 moves into the inner cavity of the placement slot 56, thereby removing the limit block 52 from both ends of the processing material. The electromagnet 58 is electrically connected to the touch switch 543;

[0030] See also Figure 3 and Figure 4 An opening is provided on one side wall of the mounting seat 54 close to the mounting block 51, and a push block 59 is installed on the outer end surface of the mounting block 51. The push block 59 is on the same horizontal line as the opening, and the upper surface of one end of the push block 59 close to the mounting seat 54 is an inclined surface. When the limit block 52 moves into the inner cavity of the placement groove 56, the push block 59 passes through the opening and is inserted into the inner cavity of the mounting groove 542, so that the inclined surface of the push block 59 contacts the bottom wall of the pressing block 55, and pushes the pressing block 55 upward, so that the pressing block 55 does not contact the touch switch 543, so that the electromagnet 58 does not work all the time when it is powered off (after the limit block 52 is retracted and does not contact the end of the processed material, the electromagnet 58 will be controlled to be powered off), which has an energy saving effect;

[0031] See also Figure 6A connecting rod 513 is slidably mounted on both the front and rear side walls of the mounting block 51. The connecting rod 513 can move left and right. A mounting frame is mounted on the outer end of the connecting rod 513. The mounting frame is located between the two sets of limit blocks 52. In the process of moving the processed material into the groove of the lower die 2, the pressure roller 515 contacts the upper surface of the processed material, which has a pressing effect, so that the processed material will not bend or wrinkle, thereby ensuring the processing quality of the processed material. In order to prevent the pressure roller 515 from affecting the two ends of the upper die 4 pressing the processed material, a second magnetic block 514 is installed on the outer end face of the limit block 52. The mounting frame is made of magnetic metal (metal material that can be adsorbed by the second magnetic block 514, such as iron, etc.). When the limit block 52 moves with the processing material, the limit block 52 will move closer to the mounting frame, and the second magnetic block 514 will adsorb and fix the mounting frame, so that when the limit block 52 moves into the inner cavity of the placement groove 56, it will also move with the mounting frame and the pressure roller 515.

[0032] Embodiment 2:

[0033] See also Figure 4 and Figure 5 On the basis of Example 1, in order to make the limit block 52 automatically retract, the component controlling the movement of the limit block 52 may also be a storage box 510, a drive motor 511 (drive motor 511 When not working, the output shaft of the drive motor 511 can rotate, so that the pull rope 512 wrapped around the outer wall of the winding rod can be released), the winding rod and the pull rope 512 and other components (these components replace the electromagnet 58 and the first magnetic block 57), the mounting seat 54 and the pressing block 55 and other components installed on the limit block 52 remain unchanged, the storage box 510 is installed on the outer wall of the mounting block 51, and the drive motor 511 is installed on the outer wall of the storage box 510, the output shaft of the drive motor 511 extends into the inner cavity of the storage box 510 and is connected to the winding rod, the outer wall of the winding rod is wrapped with a pull rope 512, the end of the pull rope 512 extends into the inner cavity of the placement groove 56 and is connected to the inner end face of the limit block 52, when the pressing block 55 presses the touch switch 543, the drive motor 511 is energized, the winding rod is rotated, the pull rope 512 is wrapped around the outer wall of the winding rod, and the limit block 52 moves into the inner cavity of the placement groove 56.

[0034] Working method: put the processing material on the top of the lower mold 2, make the limit blocks 52 of the two limit mechanisms 5 contact the two ends of the processing material, press the two ends of the processing material, and then turn on the power to make the hydraulic push rod move the upper mold 4 downward to contact the processing material, and press the processing material into the groove of the lower mold 2. In this process, the middle part of the processing material extends into the groove of the lower mold 2, and the two ends of the processing material will move together, and will move with the limit blocks 52, and pull the limit blocks 52 to the outside of the inner cavity of the placement groove 56 to ensure that the limit blocks 52 press the two ends of the processing material, and the upper mold 4 is close to the lower mold 2, and most of the processing material enters the groove of the lower mold 2. When the upper die 4 is in contact with the pressing block 55, the pressing block 55 is pushed downward to remove the insert block from the slot. Under the action of the elastic element 544, the pressing block 55 moves downward to press the touch switch 543, so that the electromagnet 58 is energized to generate magnetic force to attract the first magnetic block 57, so that the limit block 52 moves into the inner cavity of the placement groove 56, and the limit block 52 is removed from the two ends of the processing material. Then the upper die 4 continues to move downward to make the processing material completely fit with the groove wall of the lower die 2, and press the two ends of the processing material flat on the upper surface of the lower die 2 to make the required automobile flanging parts. After the processing is completed, the hydraulic push rod moves the upper die 4 upward and resets, and then the automobile flanging material is taken out.
