[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] Example 1

[0028] like Figures 1 to 8 As shown, it is the first embodiment of the present invention, which provides a triangular gold wire riveting pressing die, including an upper die and a lower die, the lower die includes a sliding reset rod 1 and an extrusion assembly 7, a clamping assembly 2 is arranged on the outer side of the sliding reset rod 1, a cylinder top block 6 is arranged between the extrusion assembly 7 and the clamping assembly 2, a tangent assembly 4 is arranged on the top of the extrusion assembly 7, and a jacking structure 5 is arranged on the bottom of the extrusion assembly 7, the upper die includes a slider punch 3, the slider punch 3 is located between the clamping assembly 2 and the cylinder top block 6, and a lever punch 8 located on the top of the jacking structure 5 is installed on the outer side of the slider punch 3;

[0029] The triangular gold wire is fed into the clamping assembly 2, and gas is introduced into the clamping assembly 2, and the clamping assembly 2 clamps the triangular gold wire transported inside, and then the internal elastic force of the sliding reset rod 1 is restored to drive the clamping assembly 2 to move inward, and the triangular gold wire also moves to the top limit of the cylinder top block 6 and the extrusion assembly 7. After that, when the upper mold is pressed downward, the air supply to the clamping assembly 2 is stopped to release the fixation of the triangular gold wire. At the same time, the cylinder top block 6 is supplied with air during the pressing process of the upper mold, so that the triangular gold wire is clamped and fixed on the extrusion assembly 7, and the slider punch 3 squeezes the clamping assembly 2, driving the clamping assembly 2 to reset, and at the same time, the lever punch 8 squeezes one end of the lifting structure 5, and the lifting structure 5 on the other end squeezes the extrusion assembly 7, driving the triangular gold wire to lift upward, and then the tangent assembly 4 cuts and feeds the triangular gold wire, and the cut triangular gold wire is pushed into the mold material belt hole by the tangent assembly 4 for forming and riveting, so that the action cycle is continuous, and the high-speed in-mold riveting effect is achieved;

[0030] The sliding reset rod 1 includes a mounting rod 101, the inner cavity of the mounting rod 101 is movably connected with a push rod 102, the outer side of the push rod 102 extends to the outside of the mounting rod 101 and is connected to the outside of the clamping assembly 2, and the push rod 102 is elastically connected to the mounting rod 101 through a spring 103;

[0031] When the slider punch 3 squeezes the clamping assembly 2, the clamping assembly 2 drives the push rod 102 to move inside the mounting rod 101, and then the push rod 102 squeezes the spring 103, so that the spring 103 is in a squeezed state at this time, and an outward pressure will be applied to the push rod 102. After the slider punch 3 releases the squeeze on the clamping assembly 2, the spring 103 drives the push rod 102 to reset the clamping assembly 2, so as to facilitate the subsequent continuous feeding process;

[0032] The clamping assembly 2 includes a cylinder fixing block 201, a clamping block 203 is movably connected inside the cylinder fixing block 201, and an air inlet hole 202 is opened at the bottom of the cylinder fixing block 201;

[0033] The air inlet 202 is connected to the air valve, and air is introduced into the inner cavity of the cylinder fixing block 201. The clamping block 203 is driven to move upward by the extrusion of the air, so that the clamping block 203 squeezes and clamps the triangular gold wire inside the cylinder fixing block 201, which is used for feeding the riveting and pressing mold;

[0034] The outer side of the clamp block 203 is connected to a spring 204, and the other end of the spring 204 is connected to the cylinder fixing block 201;

[0035] When gas is introduced into the cylinder fixing block 201 through the air inlet 202, the clamping block 203 moves upward to clamp and fix the triangular gold wire, thereby driving the triangular gold wire and the clamping assembly 2 to move inward through the sliding reset rod 1, making it easier to feed the triangular gold wire. At this time, since the spring 204 is in an extruded state, a downward pressure will be applied to the clamping block 203, making it easier to drive the clamping block 203 to release the clamping of the triangular gold wire.

[0036] The left side of the bottom of the slider punch 3 is inclined, and an air inlet is provided at the bottom of the cylinder top block 6;

[0037] Through the design of the slider punch 3, when the upper mold and the lower mold are merged, the slider punch 3 is used to squeeze between the clamping component 2 and the cylinder top block 6. The bottom of the slider punch 3 can be better inserted between the cylinder top block 6 and the clamping component 2 through the inclined surface at the bottom of the cylinder top block 6, so that the push rod 102 is squeezed into the inside of the mounting rod 101 through the clamping component 2. At the same time, an air inlet is opened at the bottom of the cylinder top block 6. By connecting the cylinder, an extrusion force is provided to the inside of the mold, so that the triangular gold wire on the top of the extrusion component 7 is clamped to prevent position movement when cutting the triangular gold wire;

[0038] The cutting assembly 4 includes a part stripping plate 401, and a cutting edge 402 is provided at the bottom of the part stripping plate 401;

[0039] When the gold wire is lifted by the extrusion assembly 7, the gold wire is cut by the cutting blade 402, and then the cut gold wire is introduced into the riveting processing area along the inner cavity of the part stripping plate 401, and is used for riveting the stamped dynamic and static pieces;

[0040] The clamping assembly 2 and the extrusion assembly 7 are both provided with triangular notches, and the size of the notches is the same as the size of the triangular gold wire;

[0041] This makes it easy for operators to limit the triangular gold wire that is delivered in, so as to prevent it from running off the track, thereby facilitating the riveting of the dynamic and static sheets.

[0042] Example 2

[0043] like Figures 2 to 3 and Figure 5 As shown, this embodiment includes the features of the embodiment 1, and the distinguishing technical feature is that the lifting structure 5 includes a lever 501, and a return spring 502 is provided at the bottom of the right side of the lever 501;

[0044] Through the elastic force of the return spring 502, one side of the driving lever 501 is tilted upward, so that when the upper mold is pressed, the lever punch 8 is driven to squeeze one side of the lever 501, so that the other side of the driving lever 501 is tilted, thereby squeezing and triggering the squeezing component 7, cutting the triangular gold wire, and performing a riveting operation with the material strip;

[0045] The extrusion assembly 7 includes a tangent positioning block 701, the interior of the tangent positioning block 701 is movably sleeved with a tangent punch 702, and the bottom of the tangent punch 702 extends to the outside of the tangent positioning block 701;

[0046] When the lever 501 is squeezed by the lever punch 8, the left side of the lever 501 is tilted up, and then the tangent punch 702 is moved upward by the squeezing of the lever 501. The tangent punch 702 squeezes the triangular gold wire in the tangent positioning block 701 upward, and the triangular gold wire is cut by the tangent blade 402. With the push of the tangent punch 702, the cut triangular gold wire moves upward along the part stripping plate 401, so as to facilitate the riveting operation of the dynamic and static pieces.

[0047] Wherein, the tangent punch 702 is elastically connected to the tangent positioning block 701 through a spring 3 703;

[0048] The elastic force of the spring 3 703 facilitates the downward movement of the tangent punch 702, facilitating the operator to reset the tangent punch 702, making it convenient for subsequent connection cycle riveting operations, thereby improving the processing efficiency of the dynamic and static sheets;

[0049] The bottom of the lever punch 8 is movably connected to the top of the right side of the lever 501, and the lever punch 8 is located above the return spring 502;

[0050] As the upper mold presses the lower mold downward, the upper mold drives the lever punch 8 to squeeze the right side of the lever 501, tilting the left side of the lever 501, thereby driving the cutting punch 702 to squeeze the triangular gold wire;

[0051] The working principle and use process of the present invention:

[0052] First, the operator guides the triangular gold wire into the clamping assembly 2 and the extrusion assembly 7, and then supplies gas into the inner cavity of the cylinder fixing block 201 through the air inlet 202. The gas drives the clamping block 203 to move upward, and the introduced triangular gold wire is clamped by the clamping block 203. Then, the elastic force of the spring 103 drives the push rod 102 to move right, so that the clamped triangular gold wire and the clamping assembly 2 move right as a whole, so that the triangular gold wire is moved to the top cutting area of ​​the tangent positioning block 701. Then, when the upper mold and the lower mold are closed, the air supply to the inside of the cylinder fixing block 201 is stopped, and the air supply is changed to the inside of the cylinder top block 6, so as to fix and clamp the triangular gold wire extending to the inside of the extrusion assembly 7. Then, the upper mold drives the lever punch 8 to move downward, so that the right side of the extrusion lever 501 is squeezed, causing the left side of the lever 501 to tilt up, and the left side of the lever 501 The tangent punch 702 is squeezed, so that the tangent punch 702 is driven to squeeze the gold wire in the cutting area, and the fixed gold wire is cut through the tangent blade 402, and then the tangent punch 702 continues to move upward, and the cut gold wire is moved along the part stripping plate 401 to the inside of the mold material belt hole for molding and riveting, so that it is processed into a dynamic and static piece. After that, when the upper mold and the lower mold are separated, the slider punch 3 is moved out from between the clamping component 2 and the cylinder top block 6, so that it releases the squeezing of the clamping component 2, and re-supplies air to the clamping component 2, and drives the clamping component 2 to feed the triangular gold wire through the elastic force of the sliding reset rod 1, and then closes for cutting and riveting, so that the gold wire enters the pressing station by utilizing the opening and closing operation of the mold, and then in the process of closing the mold, riveting and wire breaking are carried out continuously, thus forming a continuous operation closed loop, which is more efficient and more continuous, and brings convenience to the operator.
