DETAILED DESCRIPTION

[0016] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0017] like Figure 1 and Figure 2 As shown, a transfer die waste removal mechanism of the utility model comprises an upper die seat 40 and a lower die seat 10, the top surface of the lower die seat 10 is arranged on the floating block 16 seat, the bottom surface of the upper die seat 40 is provided with a fixing plate 44 corresponding to the concave die plate 14, the concave die plate 14 is provided with a floating block 16, the floating block 16 is provided with a first groove 18, the fixing plate 44 is provided with a punch 46 corresponding to the floating block 16, the end of the punch 46 is provided with a guide block 48 corresponding to the first groove 18, the periphery of the floating block 16 is provided with a lower die blade 20 for cutting off the waste 54, and the lower die seat 10 is provided with a separation component for separating the waste 54 from the punch 46 and a blowing component for blowing away the separated waste 54;

[0018] The product 52 is placed in the first groove 18, and the guide block 48 extends into the first groove 18, first contacting the product 52 to correct the position of the product 52, and then the punch 46 and the lower die blade 20 cut off the waste 54 on the product 52, and then the punch 46 will lift the waste 54 during the rising process, and then the separation component will separate the waste 54 from the punch 46. After the waste 54 separates from the punch 46 and falls, the blowing component will blow the waste 54 away to prevent the waste 54 from falling on the floating block 16 below and affecting the subsequent stamping.

[0019] A lower pad 12 is provided between the lower die base 10 and the concave die plate 14, and an upper pad 42 is provided between the upper die base 40 and the fixed plate 44;

[0020] The hardness of the upper pad 42 and the lower pad 12 is greater than that of the upper die base 40 and the lower die base 10 , and can protect the upper die base 40 and the lower die base 10 and bear the force generated during stamping and blanking.

[0021] The concave mold plate 14 and the lower pad 12 are jointly provided with a second groove 22. The cross section of the first groove 18 is inverted T-shaped. The floating block 16 is slidably arranged in the second groove 22. The bottom diameter of the floating block 16 is larger than the top diameter of the second groove 22. An elastic member is arranged between the bottom of the floating block 16 and the lower mold base 10. The elastic member can be a spring 26.

[0022] The top of the float block 16 protrudes from the concave template 14. During the downward movement of the upper die seat 40, the float block 16 receives the downward force applied to it by the guide block 48. The float block 16 moves downward until the top surface of the float block 16 is located below the top surface of the lower die blade 20, so that the punch 46 contacts the product 52. The punch 46 and the lower die blade 20 apply force to the product 52 to cut off the waste material 54 on the product 52. After completion, after the punch 46 moves upward, the float block 16 moves upward under the action of the spring 26. The diameter of the bottom of the float block 16 is greater than the diameter of the second groove 22, which can effectively prevent the float block 16 from detaching from the second float block 16 under the action of the spring 26.

[0023] The lower die base 10 is provided with a third groove 24 connected to the second groove 22. The diameter of the third groove 24 is smaller than the diameter of the bottom of the floating material block 16. The elastic member is disposed in the third groove 24.

[0024] The diameter of the third groove 24 is smaller than the diameter of the bottom of the floating block 16 , which can prevent the floating block 16 from being excessively displaced and exceeding the maximum deformation of the spring 26 , thereby damaging the spring 26 .

[0025] The separation assembly includes a baffle 30, which is connected to the lower die base 10 through a fixing base 28. A through slot 32 is provided on the baffle 30 for the punch 46 to pass through, and the diameter of the through slot 32 is adapted to the diameter of the punch 46.

[0026] When the punch 46 passes through the through slot 32 and the punch 46 drives the waste material 54 to move upward, the baffle 30 blocks the waste material 54 so that the waste material 54 cannot move upward with the punch 46 , thereby separating the waste material 54 from the punch 46 .

[0027] The air blowing assembly is disposed at the bottom of the baffle 30, and the air outlet of the air blowing assembly faces the bottom of the through slot 32;

[0028] The air blowing component may be an air gun 34 or a blower. When the waste material 54 is falling away from the punch 46 , the air gun 34 blows air toward the waste material 54 , causing the waste material 54 to deviate from the original motion trajectory and fall to an area far away from the floating material block 16 .

[0029] An inner guide sleeve 38 is installed in the concave template 14, a fourth groove 36 corresponding to the inner guide sleeve 38 is provided on the lower pad 12, and an inner guide column 50 corresponding to the inner guide sleeve 38 is provided at the bottom of the fixed plate 44;

[0030] The inner guide sleeve 38 plays a positioning role. When the upper mold base 40 moves downward, the inner guide column 50 passes through the inner guide sleeve 38 to the fourth groove 36, which limits the upper mold base 40 and prevents the upper mold base 40 from moving downward excessively and causing damage to the guide block 48 or the mold.

[0031] Working principle: When in use, the product 52 is placed on the floating block 16, and the upper die seat 40 moves downward to make the guide block 48 extend into the second groove 22. During this process, the guide block 48 first contacts the product 52 and exerts a force on the product 52 to make the position of the product 52 more closely fit the floating block 16. During the downward movement of the upper die seat 40, when the force exerted by the guide block 48 on the floating block 16 is greater than the elastic force of the spring 26, the floating block 16 will move downward so that the top of the floating block 16 is located at the lower die cutting edge. 20, the punch 46 and the lower die blade 20 exert force on the product 52 to cut off the excess waste 54 on the product 52, and then the upper die base 40 moves up with the waste 54. When the bottom of the punch 46 moves to the baffle 30, the baffle 30 blocks the waste 54. After the waste 54 separates from the punch 46, it falls under the action of gravity. During the falling process, the air flow ejected by the air gun 34 will keep the waste 54 away from the floating block 16 and will not affect the subsequent processing.

[0032] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.

[0033] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
