Description

Technical Field

[0001] The utility model relates to the technical field of punching dies, in particular to a punching mechanism of a punching die. Background Art

[0002] A punching die is a tool used to perform punching processing on materials. Its structural design is critical to achieving accurate and efficient punching. A typical punching mechanism is mainly composed of a punch, a die, and a clamping device. The punch usually adopts a quick-change structure and is designed in a stepped shape to facilitate quick installation and replacement. The die is another important part that cooperates with the punch to complete the punching operation. The two together form the basic structure of the blanking die. However, when the existing stamping die drives the reset of the punch through elastic parts such as springs, the elastic parts such as springs are prone to failure after long-term use, resulting in the punch being unable to reset normally, which is not conducive to oblique punching processing of components.

[0003] In order to address the above problems, the Chinese patent with the existing announcement number CN218460601U proposes an oblique punching mechanism and an oblique punching die. The device drives the oblique punch to move downward by an oblique pressure plate, and compresses the elastic part so that the elastic part stores elastic potential energy. During stamping, the rebound force of the elastic part drives the oblique pressure plate and the oblique punch to reset, so as to facilitate the stamping of the next part to be stamped.

[0004] However, although the above-mentioned oblique punching mechanism and oblique punching die can drive the oblique punch to move obliquely downward through the oblique pressure plate and compress the elastic part, so that the elastic part can drive the oblique pressure plate and the oblique punch to reset, when the oblique punching mechanism and the oblique punching die are used to punch objects, it is difficult for the operator to accurately align the specific punching position of the object to be punched with the oblique punch, resulting in unqualified punching of the object. Therefore, the utility model provides a punching mechanism of a punching die to meet the demand. Utility Model Content

[0035] like Figures 1 to 6 As shown, an embodiment of the utility model provides a punching mechanism of a punching die, including a base 1, a support frame 2 is provided on the top, an electric push rod 3 is provided on the support frame 2, a fixed block 4 is provided at the bottom of the electric push rod 3, a punch 5 is provided at the bottom of the fixed block 4, a die 6 is provided on the base 1 opposite to the punch 5, at least two hinged rods 13 are symmetrically arranged along the fixed block 4, the hinged rod 13 is hinged to the fixed block 4 through a hinge 17, an infrared transmitter 14 is provided at the bottom of the hinged rod 13, and an adjustment component 9 is provided in the fixed block 4 for driving the hinged rods 13 arranged in opposition to each other to rotate relative to each other along the hinge 17.

[0036] Specifically, the object to be punched is placed on the die 6, and then the hinge rod 13 is driven to rotate relatively along the hinge 17 through the adjustment component 9, so that the hinge rod 13 drives the light source emitted by the infrared transmitter 14 to converge on the object to be punched in the die 6. When the light sources of multiple infrared transmitters 14 overlap, the overlapping position of the light source is opposite to the punch 5, so that the punching position of the object to be punched can be judged according to the position of the light source, thereby ensuring the qualified rate of the punching of the object, and solving the problem that when the existing punching mechanism is used to punch the object, it is difficult for the operator to accurately align the specific punching position of the object to be punched with the inclined punch, thereby causing the object to be unqualified.

[0037] It should be noted that, in the present embodiment, the fixed block 4 is a cylindrical structure, the hinged rods 13 are in two groups, and the supports are arranged in two groups of the fixed block 4. In other embodiments, the number of hinged rods 13 is not limited. In addition, the punch 5 is arranged coaxially with the fixed block 4 to ensure that the light source when multiple infrared emitters 14 converge is arranged coaxially with the fixed block 4 and the punch 5.

[0038] like Figure 1 , Figure 5 and Figure 6As shown, in this embodiment, the adjustment component 9 includes a turntable 93, which is rotatably arranged in the fixed block 4 through a rotating shaft 94, and a second connecting rod 92 of the same amount as the hinge rod 13 is relatively hinged on the turntable 93, a connecting rod 1 91, a first end of which is hinged to the top of the hinge rod 13, and a second end of the connecting rod 1 91 is hinged to the second connecting rod 92, and the connecting rod 1 91 is movably arranged on the fixed block 4, and a worm gear mechanism 95 is arranged in the fixed block 4 and is used to drive the rotating shaft 94 to rotate, the worm gear is sleeved on the rotating shaft 94, and the worm gear is movably arranged on the fixed block 4 and meshes with the worm gear, and the second connecting rod 92 relatively arranged on the turntable 93 The directions between them are opposite, and a through hole 15 is penetrated on the fixed block 4 for the movement of the connecting rod 1 91. Specifically, in the present embodiment, the number of the connecting rod 1 91 and the connecting rod 2 92 are both roots, and the two connecting rods 2 92 are respectively hinged on both sides of the turntable 93, and the directions of the two connecting rods 2 92 are opposite. The worm drives the worm wheel to rotate, the worm wheel drives the rotating shaft 94 to rotate, and the rotating shaft 94 drives the turntable 93 to rotate, thereby driving the relatively arranged connecting rods 2 92 and connecting rod 1 91 to move relative to each other, thereby driving the hinged rod 13 to rotate relative to each other. The overall operation is simple, and it is convenient to control the rotation of multiple groups of infrared transmitters 14 at the same time.

[0039] like Figure 1 As shown, in this embodiment, a through hole 10 is penetrated through the top of the die 6 , and a discharge groove 7 communicating with the through hole 10 is penetrated through the inside of the die 6 .

[0040] like Figure 3 and Figure 4As shown, in the present embodiment, a push plate 16 is movably arranged in the discharge chute 7, and a push assembly 8 for pushing the push plate 16 to slide is arranged on the base 1, and the push assembly 8 includes a push rod 81, which is fixedly connected to the push plate 16, and the push rod 81 is movably arranged on the die 6, and a triangular plate 84, whose three corners are respectively hinged with a movable rod 82, a fixed rod 83 and an L-shaped rod 85, and one end of the fixed rod 83 away from the triangular plate 84 is fixedly connected to the die 6, and one end of the movable rod 82 away from the triangular plate 84 is hinged to the push rod 81, and one end of the L-shaped rod 85 away from the triangular plate 84 is fixedly connected to the fixed block 4. Specifically, when the electric push rod 3 drives the fixed block 4 to descend, the fixed block 4 drives the L-shaped rod 85 to descend, and the L-shaped rod 85 drives the triangular plate 84 The triangular plate 84 rotates, and the push rod 81 is driven to move through the movable rod 82, so that the push rod 81 drives the push plate to slide along the discharge groove 7, thereby discharging the waste material that has fallen into the through hole 10 into the discharge groove 7; it should be noted that when the electric push rod 3 drives the punch 5 to contact the object, the position of the push plate has not reached the connection point between the through hole 10 and the discharge groove 7. When the punch 5 has completed punching, the waste material falls into the discharge groove 7 along the through hole 10. At this time, the electric push rod 3 continues to drive the punch 5 to descend, and the push plate continues to move forward and pushes out the waste material at the connection between the through hole 10 and the discharge groove 7. At the same time, the length of the through hole 10 is greater than the length of the pressure plate moved after pushing the waste material along the discharge groove 7, so as to ensure that the punch 5 does not contact the push plate. The specific adjustment can be made according to the actual situation.

[0041] like Figure 1 and Figure 2 As shown, in this embodiment, a slide bar 11 is fixedly connected between the support frame 2 and the base 1 , a connecting rod 12 is sleeved on the slide bar 11 , and one end of the connecting rod 12 away from the slide bar 11 is fixedly connected to the fixing block 4 .

[0042] Working principle:

[0043] First, the electric push rod 3 and the infrared transmitter 14 are connected to the power supply, and the object to be punched is placed on the die 6. The worm drives the worm wheel to rotate, the worm wheel drives the rotating shaft 94 to rotate, and the rotating shaft 94 drives the turntable 93 to rotate, thereby driving the relatively arranged connecting rod 2 92 and connecting rod 1 91 to move relative to each other, thereby driving the hinged rod 13 to rotate relative to each other, so that the hinged rod 13 drives the light source emitted by the infrared transmitter 14 to converge on the object to be punched in the die 6. When the light sources of multiple infrared transmitters 14 overlap, the overlapping position of the light source is opposite to the punch 5, so that the punching position of the object to be punched can be judged according to the position of the light source, thereby ensuring the qualified rate of the object punching, and solving the problem that when the existing punching mechanism is used to punch the object, it is difficult for the operator to accurately align the specific punching position of the object to be punched with the oblique punch, thereby causing the object to be unqualified.
