Detailed Description
The following detailed description of the present invention will be made with reference to the accompanying drawings and examples.
As shown in fig. 1 and 2, the utility model provides a protection device for a buffering and limiting structure of a stamping die, which comprises an upper die 1 and a lower die 3, wherein a set of sleeves 2 is fixed at the bottom of the upper die 1, a set of mounting seats 4 is detachably connected at the top of the lower die 3, a vertical rod 41 is connected at the top of the mounting seats 4 by screw threads, and a limiting and buffering component is arranged on the vertical rod 41; a micro motor 5 is connected in the vertical rod 41 in a sliding manner, a connecting rod 51 moving along with the limiting and buffering component is fixed on a rotating shaft of the micro motor 5, fixed blocks 52 positioned in the vertical rod 41 are fixed on two sides of the connecting rod 51, and limiting blocks 6 positioned below the fixed blocks 52 are fixed on two sides of the inner wall of the vertical rod 41; and a control assembly for controlling the running of the micro motor 5 is arranged in the mounting seat 4.
As shown in fig. 1, the limiting buffer assembly comprises a fixing ring 42 sleeved on a vertical rod 41, a spring 43 sleeved with the vertical rod 41 is fixed at the top of the fixing ring 42, a fixing cylinder 44 is fixed at one end of the spring 43 departing from the fixing ring 42, the top of the vertical rod 41 is located in the fixing cylinder 44, the fixing cylinder 44 and the sleeve 2 are symmetrically distributed up and down, and one end of the connecting rod 51 departing from the micro motor 5 is rotatably connected with the top of the fixing cylinder 44. When the upper die 1 moves downwards under the action of the press machine, the sleeve 2 pushes the fixed cylinder 44 downwards along with the downward movement, the fixed cylinder 44 extrudes the spring 43, the connecting rod 51 drives the micro motor 5 to move downwards along with the fixed cylinder 44, the effect of limiting and buffering the downward movement of the upper die 1 is achieved, and the vibration generated by the die during stamping is reduced.
As shown in fig. 2, the bottom of the fixing block 52 is fixed with a fixing rod 53, the top of the limiting block 6 is provided with a concave hole 61, and the inner diameter of the concave hole 61 is arranged in a manner of being thick at the top and thin at the bottom. When the machine breaks down and leads to going up mould 1 and moving downwards suddenly, when fixed cylinder 44 promoted connecting rod 51 downwards, dead lever 53 then inserted in shrinkage pool 61, and shrinkage pool 61 internal diameter is thick setting thin from top to bottom, has certain cushioning effect when making connecting rod 51 move downwards, avoids dead lever 53 directly to strike stopper 6.
As shown in fig. 1 and 2, the control assembly includes a rechargeable battery 7 fixed in the mounting seat 4, a connection line 71 is connected to the rechargeable battery 7, and one end of the connection line 71 away from the rechargeable battery 7 penetrates through the mounting seat 4 to be connected with the micro motor 5; a lead 72 penetrating through the mounting seat 4 is connected between two adjacent rechargeable batteries 7, the lead 72 is positioned in a groove formed in the top of the lower die 3, and a control panel 73 is fixed on one side of the lower die 3. The rechargeable battery 7 supplies power to the micro motor 5 through a connecting wire 71 to control the operation of the micro motor 5, and the group of rechargeable batteries 7 are connected through a conducting wire 72 to enable the control panel 73 to control the on and off of the micro motor 5.
As shown in fig. 1, the mounting seat 4 is located in a groove formed in the top of the lower mold 3, mounting blocks 8 are fixed on both sides of the mounting seat 4, and the mounting blocks 8 are fixedly connected with the lower mold 3 through screws. After the mounting seat 4 is placed in the groove formed in the top of the lower die 3, the mounting block 8 and the lower die 3 can be fixed together by using bolts, so that an operator can take out the mounting seat 4 for overhauling.
As shown in FIG. 2, a sponge pad 74 is fixed on the top of the mounting seat 4 and positioned in the vertical rod 41. The sponge pad 74 can protect the micro-motor 5 by contacting the bottom of the micro-motor 5 with the sponge pad 74 when the micro-motor 5 slides downwards.
When the material stamping die is used, the group of mounting seats 4 and the group of sleeves 2 are distributed in a rectangular array, when an operator places a material on the lower die 3, the operator takes out an arm to press a switch on the control panel 73, a rotating shaft of the micro motor 5 drives the connecting rod 51 to rotate 90 degrees, so that the fixed block 52 and the limiting block 6 are staggered, then the upper die 1 moves downwards, the sleeve pushes the fixed cylinder 44 to extrude the spring 43, and the connecting rod 51 drives the micro motor 5 to slide downwards, so that the upper die 1 finishes stamping the material; after the upper die 1 recovers, the fixed cylinder 44 drives the connecting rod 51 to slide upwards for recovery, an operator presses a switch on the control panel 73 to enable the micro motor 5 to rotate 90 degrees, the fixed block 52 is opposite to the limiting block 6, when the machine fails to enable the upper die 1 to move downwards suddenly, the fixed cylinder 44 is squeezed to push the connecting rod 51 to move downwards, and the limiting block 6 supports the fixed block 52 to prevent the upper die 1 from moving downwards, so that enough reaction time is provided for the operator; meanwhile, a part of the limiting block 6 penetrates through the inner wall of the vertical rod 41 and is flush with the outer wall of the vertical rod 41, so that the firmness of connection between the limiting block 6 and the vertical rod 41 can be effectively improved.
Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
