[0001] The utility model relates to the technical field of stamping, in particular to a hot stamping device for an aluminum inner ring of a brake disc. Background Art

[0002] As a type of brake disc, aluminum-iron composite brake discs are lighter in weight, thereby reducing the weight of the entire vehicle, which can improve fuel efficiency, steering performance and acceleration performance. The existing aluminum inner ring of the brake disc usually requires hot stamping equipment during the processing.

[0003] The existing aluminum inner ring of the brake disc is exposed during the hot stamping process, and there is no protective mechanism around the equipment. During the stamping process, the workpiece or tool with a high temperature may slip from the work platform, thereby endangering the safety of the workers around the equipment. Utility Model Content

[0004] The purpose of the utility model is to solve the following shortcomings in the prior art: the existing brake disc aluminum inner ring is in an exposed state during the hot stamping process, and no protective mechanism is set around the equipment. During the stamping process, the workpiece or tool with a high stamping temperature may slip from the work platform, thereby endangering the safety of the staff located around the equipment. A brake disc aluminum inner ring hot stamping equipment is proposed.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A hot stamping device for an aluminum inner ring of a brake disc comprises a platform, a placement plate fixedly mounted on the upper surface of the platform, a hydraulic cylinder fixedly mounted on the lower surface of the placement plate, a pressure plate fixedly mounted on the bottom end of the drive shaft of the hydraulic cylinder, and a mold for placing the aluminum inner ring of the brake disc fixedly mounted on the upper surface of the platform;

[0007] The driving shaft surface of the hydraulic cylinder is fixedly installed with a connecting plate through multiple connecting rods, and both ends of the connecting plate are fixedly installed with a movable plate, and the surface of the platform body is provided with a mounting groove, and the upper surface of the platform body is symmetrically provided with mounting openings, and the two movable plates are respectively vertically slidably arranged in the two mounting openings, and the upper surface of the platform body is symmetrically provided with slides for horizontal sliding, and the surface of the slide plate is fixedly installed with a mounting plate, and the two mounting plates are different in size. The larger mounting plate is horizontally provided with a socket on a side close to the smaller mounting plate, and the side wall of the slide plate is fixedly installed with an inclined plate, and the surface of the inclined plate is provided with an inclined opening, and a sliding rod is slidably arranged in the inclined opening, and the two sliding rods are respectively fixedly connected to the two movable plates.

[0008] Preferably, the lower surfaces of the mounting plate and the slide plate are provided with a plurality of spherical grooves, in which rolling balls are embedded and rolled, and the rolling balls are in rolling contact with the platform body.

[0009] Preferably, the mounting plate is made of transparent material.

[0010] Preferably, the inner bottom wall of the mold is provided with a through opening passing through the mounting groove, and a pair of first spring rods are fixedly mounted on the left and right groove walls of the mounting groove, and a baffle is fixedly mounted on one end of each pair of the first spring rods, and the movement of the baffle is controlled by the pressing assembly.

[0011] Preferably, the pressure component includes a push rod, a first force plate and a second force plate, the two push rods are respectively rotatably installed on the surface of the bottom end of the two movable plates, the two first force plates are respectively tilted and fixedly installed on the lower surface of the two baffles, the two second force plates are respectively rotatably installed on the surface of the two first force plates through the rotating shaft, the surface of the first force plate is fixedly installed with an arc-shaped second spring rod with the rotating shaft as the center, the end of the second spring rod away from the first force plate is fixedly connected to the surface of the second force plate, and the two push rods correspond to the positions of the two second force plates respectively.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. When the hydraulic cylinder moves the pressure plate downward, the two movable plates, two inclined plates and two sliding rods cooperate to move the two slide plates and two mounting plates closer to each other, thereby covering the pressure plate, the die and the aluminum inner ring of the brake disc with a higher temperature. This allows the hot stamping to be carried out in a relatively closed space, preventing the workpiece or tool with a higher temperature from sliding off the table during the stamping process, thereby endangering the safety of the workers around the equipment. When the stamping is completed and the pressure plate moves upward, the two slide plates and two mounting plates will move away from each other, making it easier for the workers to pick up or place the aluminum inner ring of the brake disc.

[0015] 2. With the cooperation between the support rod, the movable plate, the first force plate and the second force plate, when the hot pressing work of the aluminum inner ring of the brake disc is completed and the pressure plate moves up, the two baffles will move away from each other, so that the hot-pressed aluminum inner ring of the brake disc falls from the opening into the installation groove, without the need for manual unloading, and the effect of automatic unloading can be achieved.

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] The terms "upper", "lower", "left", "right", "middle" and "one" used in the present invention are only for the convenience of description and are not intended to limit the scope of application of the present invention. Changes or adjustments to their relative relationships shall be deemed to be within the scope of application of the present invention without substantially changing the technical content.

[0026] Reference Figure 1-Figure 7 A hot stamping device for an aluminum inner ring of a brake disc comprises a platform 1, a placement plate fixedly mounted on the upper surface of the platform 1, a hydraulic cylinder 2 fixedly mounted on the lower surface of the placement plate, a pressing plate 3 fixedly mounted on the bottom end of the drive shaft of the hydraulic cylinder 2, and a mold 4 for placing the aluminum inner ring of the brake disc fixedly mounted on the upper surface of the platform 1;

[0027] The driving shaft surface of the hydraulic cylinder 2 is fixedly installed with a connecting plate 6 through a plurality of connecting rods 5, and a movable plate 7 is fixedly installed at both ends of the connecting plate 6. A mounting groove is provided on the surface of the platform body 1, and a mounting opening is symmetrically provided on the upper surface of the platform body 1. The two movable plates 7 are respectively vertically slidably configured in the two mounting openings, and a slide plate 8 is symmetrically and horizontally slidably provided on the upper surface of the platform body 1. A mounting plate 9 is fixedly installed on the surface of the slide plate 8. The two mounting plates 9 are of different sizes. A socket 10 is horizontally provided on a side of the larger mounting plate 9 close to the smaller mounting plate 9. An inclined plate 11 is fixedly installed on the side wall of the slide plate 8. An inclined opening 12 is provided on the surface of the inclined plate 11, and a sliding rod 13 is slidably provided in the inclined opening 12. The two sliding rods 13 are respectively fixedly connected to the two movable plates 7, and the mounting plate 9 is made of transparent material;

[0028] First, place the aluminum inner ring of the brake disc to be hot-pressed in the mold 4, then start the hydraulic cylinder 2 to control the downward movement of the pressure plate 3. During the downward movement, the two movable plates 7 will respectively carry two slide rods 13 to slide in the two bevels 12. Under the action of the inclined surface, the two slide plates 8 and the two mounting plates 9 will move closer to each other in the horizontal direction, and in this process, the smaller mounting plate 9 will enter the socket 10 opened on the surface of the larger mounting plate 9, thereby covering the pressure plate 3, the mold 4 and the higher temperature aluminum inner ring of the brake disc, so that the hot stamping is carried out in a relatively closed space, avoiding the high temperature workpiece or tool being stamped from sliding off the table 1 during the stamping process, thereby endangering the safety of the staff around the equipment. When the stamping is completed and the pressure plate 3 moves upward, the two slide plates 8 and the two mounting plates 9 will move away from each other, making it easier for the staff to take or place the aluminum inner ring of the brake disc. During the hot pressing process, the staff can observe the hot pressing situation through the transparent mounting plate 9.

[0029] The lower surfaces of the mounting plate 9 and the skateboard 8 are provided with a plurality of spherical grooves, in which rolling balls are embedded and rolled in the spherical grooves. The rolling balls are in rolling contact with the platform 1. The rolling balls can reduce the friction between the contact surfaces of the mounting plate 9 and the skateboard 8 and the platform 1, thereby avoiding jamming during movement.

[0030] The bottom wall of the mold 4 is provided with a through-opening that passes through the mounting groove, and a pair of first spring rods 14 are fixedly installed on the left and right groove walls of the mounting groove, and a baffle 15 is fixedly installed on one end of each pair of first spring rods 14, and the baffle 15 is controlled to move by a pressing assembly. The pressing assembly includes a push rod 16, a first force-bearing plate 17 and a second force-bearing plate 18, and the two push rods 16 are rotatably mounted on the surface of the bottom end of the two movable plates 7, and the two first force-bearing plates 17 are respectively tilted and fixedly mounted on the lower surface of the two baffles 15, and the two second force-bearing plates 18 are respectively rotatably mounted on the surface of the two first force-bearing plates 17 through a rotating shaft 19. An arc-shaped second spring rod 20 with the rotating shaft 19 as the center is fixedly installed on the surface of the first force-bearing plate 17, and one end of the second spring rod 20 away from the first force-bearing plate 17 is fixedly connected to the surface of the second force-bearing plate 18, and the two push rods 16 correspond to the positions of the two second force-bearing plates 18 respectively. The elastic force of the second spring rod 20 is less than the elastic force of the first spring rod 14;

[0031] When the second plate 18 is in the state of being pressed, the two support rods 16 will respectively contact the upper surface of the two second force-bearing plates 18. When the second plate 18 is pressed, the second force-bearing plates 18 will rotate. The second spring rod 20 will shrink at this time until the support rod 16 moves down and no longer contacts the second plate 18. At this time, the pressure exerted by the support rod 16 on the second plate 18 disappears, and the second plate 18 will quickly rotate and reset under the elastic potential energy of the second spring rod 20. At this time, the two support rods 16 will correspond to the lower surface positions of the two second force-bearing plates 18 respectively. When the hot pressing is completed and the pressure plate 3 and the two movable plates 7 move up, the two support rods 16 will respectively contact the lower surface positions of the two second force-bearing plates 18. The two baffles 15 will quickly move and reset under the elastic potential energy of the multiple first spring rods 14, and resist each other again, thereby closing the through-hole, making it convenient to place the subsequent brake disc aluminum inner ring to be processed, that is, no manual unloading is required, and the effect of automatic unloading can be achieved. In addition, since the hot-pressed brake disc aluminum inner ring may still have a high temperature, there is a risk of manual handling.

[0032] A plurality of telescopic springs 21 are fixedly mounted on the bottom wall of the mounting groove, and a sponge plate 22 is fixedly mounted on the top of the plurality of telescopic springs 21;

[0033] Therefore, the aluminum inner ring of the brake disc falling from the opening will fall on the sponge plate 22, and the multiple telescopic springs 21 can play a buffering and shock-absorbing effect to prevent the aluminum inner ring of the brake disc from directly colliding with the wall of the installation groove and being damaged.

[0034] When the pressing plate 3 is moved upward, the two slide plates 8 and the two mounting plates 9 will move closer to each other in the horizontal direction, and in this process, the smaller mounting plate 9 will enter the socket 10 opened on the surface of the larger mounting plate 9, thereby covering the pressing plate 3, the mold 4 and the higher temperature aluminum inner ring of the brake disc, so that the hot stamping is carried out in a relatively closed space, avoiding the workpiece or tool with higher temperature from sliding off the table 1 during the stamping process, thereby endangering the safety of the staff located around the equipment. When the stamping is completed and the pressing plate 3 moves upward, the two slide plates 8 and the two mounting plates 9 will move away from each other, making it convenient for the staff to take or place the aluminum inner ring of the brake disc.

[0035] In the present invention, unless otherwise clearly specified or limited, the terms “installed”, “connected”, “connected”, “fixed” and the like should be understood in a broad sense.

[0036] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
