[0002] A car luggage rack refers to two plates installed on the roof of a car and used to install and fix the luggage rack crossbeam. A car luggage rack is a device installed on the roof of a car to place items. It is generally used in hatchback station wagons, SUVs, MPVs and other models. Car luggage racks are most commonly used for self-driving travel. They are used in conjunction with roof boxes and roof frames to carry travel luggage to increase the space inside the car. Other sports equipment such as skis, bicycles, and sailboats can also be carried. When using a car luggage rack, first place the luggage on the surface of the luggage rack, and then use straps to limit it to prevent the luggage from falling while the car is driving. When producing a car luggage rack, the bottom plate of the car luggage rack needs to be stamped, so stamping equipment is needed for stamping work.

[0019] The present invention provides a stamping forming device for a bottom plate of a car luggage rack, which has the following beneficial effects:

[0020] 1. The stamping forming device of the bottom plate of the automobile luggage rack utilizes the extension of the lifting column to drive the movable mold base to move downward, thereby causing the punch and the pressing teeth to move downward together. As the pressing teeth continue to descend, the pressing teeth can be used to apply pressing force to the swing push rod on the auxiliary component, thereby facilitating the limiting of the bottom plate of the automobile luggage rack. At the same time, the punch moves downward to stamp the bottom plate of the automobile luggage rack, and utilizes the arc surface to contact the top of the bottom plate of the automobile luggage rack. Under the action of the stamping force, it is convenient to stamp and bend the end of the bottom plate of the automobile luggage rack, and the end of the bottom plate of the automobile luggage rack is brought into surface contact with the arc surface, thereby increasing the contact area, making it difficult to cause damage to the end of the bottom plate of the automobile luggage rack, thereby achieving a good stamping effect.

[0021] Second, the stamping forming device of the automobile luggage rack bottom plate can use the inner surface of the groove body to contact the side surface of the automobile luggage rack bottom plate material, thereby initially limiting the automobile luggage rack bottom plate material, and it is not easy to be skewed. As the stamping force increases, the end of the automobile luggage rack bottom plate material is bent, and the rotating roller can rotate at this time. At this time, rolling friction is adopted between the rotating roller and the automobile luggage rack bottom plate material, and it is not easy to cause scratches on the surface of the automobile luggage rack bottom plate material.

[0022] 3. The stamping forming device of the bottom plate of the automobile luggage rack can use the end of the ball head connecting rod to apply a pressing force to the trapezoidal elastic part. At this time, the pressed trapezoidal elastic part is deformed, and the sliding blocks symmetrical on both sides slide toward both sides, and the tension spring is stretched and moves upward with the punch. At this time, the punching force disappears, and under the elastic force of the trapezoidal elastic part and the tension spring, the end of the ball head connecting rod is subjected to the upward urging force of the trapezoidal elastic part. At this time, the ball head connecting rod drives the rotating roller to rotate in the opposite direction for reset, which is convenient for subsequent reciprocating use and can be adapted to large-scale stamping processing.

[0023] Fourth, in the stamping forming device of the bottom plate of the automobile luggage rack, when the ball head connecting rod pushes the rotating roller to rotate in the opposite direction for resetting, the ejecting teeth will rotate in the opposite direction with the rotating roller. At this time, the top end of the rotating roller will lift the bottom plate of the automobile luggage rack in the groove body, so that the bottom plate of the automobile luggage rack is separated from the groove body, thereby realizing the function of unloading.

[0024] 5. The stamping forming device of the bottom plate of the automobile luggage rack can use the bottom end of the pressing tooth to contact the top end of the swing push rod as the pressing tooth moves downward, and then the pressing tooth can be used to continue to move downward. At this time, the swing push rod is pressed by the pressing tooth, so that the bottom end of the swing push rod pushes the plane baffle upward, and under the guidance of the block, the symmetrical plane baffles on both sides move vertically upward together, so as to block the end of the bottom plate material of the automobile luggage rack in the groove body, thereby preventing the bottom plate material of the automobile luggage rack from being easily offset, and making the stamping accurate.

[0025] 6. The stamping forming device of the bottom plate of the automobile luggage rack moves downward with the movable mold base and moves upward using the flat baffle. At this time, the top end of the flat baffle is inserted into the rectangular guide hole, so that the movable mold base moving downward can move smoothly downward under the guidance of the flat baffle, reducing the influence of external force and vibration, and is not prone to shaking.

Through the support of the machine head 2 and the lifting column 51, the output end of the lifting column 51 drives the movable mold base 52 to move downward, thereby causing the punch 53 and the pressing teeth 55 to move downward together. As the pressing teeth 55 continue to descend, the pressing teeth 55 can be used to apply a pressing force to the swing push rod 73 on the auxiliary component 7, thereby facilitating the limiting of the bottom plate of the automobile luggage rack;

[0041] At the same time, the punch 53 moves downward to stamp the bottom plate of the automobile luggage rack, and uses the curved surface 54 to contact the top of the bottom plate of the automobile luggage rack. Under the action of the stamping force, it is convenient to stamp and bend the end of the bottom plate of the automobile luggage rack, and make the end of the bottom plate of the automobile luggage rack come into surface contact with the curved surface 54, thereby increasing the contact area and not easily causing damage to the end of the bottom plate of the automobile luggage rack, thereby achieving a good stamping effect.

[0042] The outer surface of the pressing tooth 55 and one side close to the punch 53 is formed into an inclined surface to facilitate applying a pressing force. Two pressing teeth 55 are provided, and the two pressing teeth 55 are symmetrically arranged along the punch 53 .

When the luggage rack floor material is placed inside the groove body 62 at the top of the fixed mold base 61, the inner surface of the groove body 62 is in contact with the side surface of the luggage rack floor material, thereby preliminarily limiting the luggage rack floor material, which is not easy to be skewed. The punch 53 is used to punch the luggage rack floor material. Under the support of the rotating roller 63 and as the punching force increases, the end of the luggage rack floor material is bent. At this time, the rotating roller 63 can rotate. At this time, rolling friction is adopted between the rotating roller 63 and the luggage rack floor material, which is not easy to cause scratches on the surface of the luggage rack floor material.

[0045] At the same time, the rotating roller 63 will drive the ball head connecting rod 64 and the ejecting tooth 65 to rotate together. At this time, the rotating ball head connecting rod 64 will apply pressing force to the reset module 67, thereby facilitating subsequent reset and making full use of the pressing force to connect the structures together.

[0046] When the ball head connecting rod 64 pushes the rotating roller 63 to rotate in the opposite direction for resetting, the ejecting teeth 65 will rotate in the opposite direction together with the rotating roller 63. At this time, the top end of the rotating roller 63 will lift up the bottom plate of the automobile luggage rack in the groove body 62, so that the bottom plate of the automobile luggage rack is separated from the groove body 62, thereby realizing the function of unloading.

[0047] The left and right ends of the outer surface of the fixed mold base 61 are provided with rotating holes that are compatible with the rotating roller 63 to facilitate the rotation of the rotating roller 63. The left and right ends of the bottom of the inner surface of the groove body 62 are provided with notches that are compatible with the ejector teeth 65.

[0048] The balls 66 are evenly distributed on the left and right ends of the outer surface of the rotating roller 63 , and the outer surface of the rotating roller 63 is provided with rotating holes matched with the balls 66 to facilitate the rolling of the balls 66 .

[0049] The reset module 67 includes a sliding block 671, the bottom of the outer surface of the sliding block 671 is slidably connected to the top of the workbench 3, a right-angle strip plate 672 is fixedly connected to the top of the workbench 3 and close to the sliding block 671, the sliding block 671 and the right-angle strip plate 672 are slidably connected, a trapezoidal spring 673 is fixedly connected to the top of the sliding block 671, the top of the trapezoidal spring 673 is in contact with the end of the ball head connecting rod 64 away from the rotating roller 63, and a tension spring 674 is fixedly connected to the side surface of the sliding block 671 and close to the right-angle strip plate 672. When the rotating roller 63 drives the ball head connecting rod 64 to move When rotating, the end of the ball head connecting rod 64 can be used to apply a pressing force to the trapezoidal elastic member 673. At this time, the pressed trapezoidal elastic member 673 is deformed, and the sliding blocks 671 symmetrical on both sides slide toward both sides, and the tension spring 674 is stretched, and moves upward with the punch 53. At this time, the punching force disappears, and under the elastic force of the trapezoidal elastic member 673 and the tension spring 674, the end of the ball head connecting rod 64 is subjected to the upward urging force of the trapezoidal elastic member 673. At this time, the ball head connecting rod 64 drives the rotating roller 63 to rotate in the opposite direction to reset, so as to facilitate the subsequent reciprocating use, and can be adapted to large-scale stamping processing;

[0050] At the same time, when the rotating roller 63 rotates, the ball 66 can roll, so that the rotating roller 63 rotates smoothly and is not prone to jamming.

[0051] A sliding groove matched with the sliding block 671 is provided on the top of the workbench 3 to facilitate the sliding of the sliding block 671, and the opening of the trapezoidal elastic member 673 faces downward.

[0052] The third embodiment, as Figure 8-Figure 9As shown, auxiliary components 7 are provided at the left and right ends of the top of the workbench 3 and near the slot body 62.

At this time, the swing push rod 73 is pressed by the pressing tooth 55 and supported by the U-shaped support frame 71, so that the bottom end of the swing push rod 73 pushes the plane baffle 75 upward, and under the guidance of the block 76, the symmetrical plane baffles 75 on both sides move vertically upward together, so that the end of the car luggage rack bottom plate material in the groove body 62 can be blocked, so that the car luggage rack bottom plate material is not easy to deviate, so that the stamping is accurate.

[0053] As the movable mold base 52 moves downward and moves upward using the flat baffle 75, the top end of the flat baffle 75 is inserted into the rectangular guide hole 56, so that the movable mold base 52 moving downward can move downward smoothly under the guidance of the flat baffle 75, reducing the influence of external force and vibration, and is not prone to shaking, thus cleverly connecting the structures together.

[0054] The swing push rod 73 is tilted, and the top of the U-shaped support frame 71 is provided with rotation holes matched with the left and right ends of the outer surface of the supporting round rod 72, so as to facilitate the rotation of the supporting round rod 72.

At this time, the bottom plate of the automobile luggage rack that needs to be punched is placed in the position of the slot 62. At this time, the bottom plate of the automobile luggage rack is initially limited. At this time, the lifting column 51 is extended, and the output end of the lifting column 51 is used to drive the movable mold base 52 to move downward, so that the punch 53 and the pressing tooth 55 move downward together. As the pressing tooth 55 continues to descend, the bottom end of the pressing tooth 55 can be used to contact the top end of the swing push rod 73, and then the pressing tooth 55 can be used to continue to move downward. At this time, the swing push rod 73 is pressed by the pressing tooth 55. The U-shaped support frame 71 is used to support the bottom end of the swing push rod 73 to push up the plane baffle 75, and under the guidance of the block 76, the plane baffles 75 on both sides are symmetrically moved vertically upward together, so that the end of the bottom plate material of the automobile luggage rack in the groove body 62 can be blocked to achieve secondary limit, and as the movable mold base 52 moves downward, the plane baffle 75 is used to move upward. At this time, the top end of the plane baffle 75 is inserted into the rectangular guide hole 56, so that the movable mold base 52 moving downward can move smoothly downward under the guidance of the plane baffle 75, and the punch 53 can be used to punch the bottom plate material of the automobile luggage rack;

[0057] When the punch 53 punches the bottom plate material of the automobile luggage rack, the end of the bottom plate material of the automobile luggage rack is bent under the support of the rotating roller 63 and as the punching force increases, the rotating roller 63 can rotate at this time. At this time, rolling friction is adopted between the rotating roller 63 and the bottom plate material of the automobile luggage rack, so that it is not easy to cause scratches on the surface of the bottom plate material of the automobile luggage rack. At the same time, the rotating roller 63 will drive the ball head connecting rod 64 and the ejecting gear 65 to rotate together. At this time, the rotating ball head connecting rod 64 will apply pressing force to the reset module 67, so as to facilitate subsequent reset;

[0058] When the rotating roller 63 drives the ball-end connecting rod 64 to rotate, the end of the ball-end connecting rod 64 can be used to apply a pressing force to the trapezoidal elastic member 673. At this time, the pressed trapezoidal elastic member 673 is deformed, and the sliding blocks 671 symmetrical on both sides slide toward both sides, and the tension spring 674 is stretched and moves upward with the punch 53. At this time, the punching force disappears, and under the elastic force of the trapezoidal elastic member 673 and the tension spring 674, the end of the ball-end connecting rod 64 is pushed upward by the trapezoidal elastic member 673. At this time, the ball-end connecting rod 64 drives the rotating roller 63 to rotate in the opposite direction to reset, so as to facilitate the subsequent reciprocating use.

[0059] When the stamping is completed, the lifting column 51 is retracted again. At this time, the movable mold base 52 drives the punch 53 to move upward. As the stamping force of the punch 53 disappears, the ejector teeth 65 will rotate in the opposite direction with the rotating roller 63. At this time, the top of the rotating roller 63 will lift the bottom plate of the automobile luggage rack in the groove body 62, so that the bottom plate of the automobile luggage rack is separated from the groove body 62, and the bottom plate of the automobile luggage rack that has been stamped can be removed.
