DETAILED DESCRIPTION

[0024] like Figure 1~Figure 4 As shown, the utility model includes a combined die clamping mechanism for producing bare copper flat wires, including a lower die mechanism 1 and a clamping device 2, and the distance between the lower die mechanism 1 and the clamping device 2 can be adjusted.

[0025] The lower mold mechanism 1 includes a lower mold box 101, which is a rectangular cavity structure with an opening on the top. Copper wire inlets and outlets 102 are provided on the opposite side walls of the lower mold box 101. The interior of the lower mold box 101 is fixedly connected with limited width strips 103 at equal intervals; the two ends of the limited width strip are respectively facing the copper wire inlet and outlet 102 on one side wall, and the limited width strip is perpendicular to the bottom end surface of the lower mold box 101.

[0026] The lower part of the width limiting strip 103 is provided with positioning slots 104 at equal intervals. The positions of the positioning slots 104 on each width limiting strip 103 are the same. A rotatable lower roller body 105 is installed on the inner bottom of the lower mold box 101. The lower roller body 105 is perpendicular to the width limiting strip 103. The lower roller body passes through the bottom of the positioning slot in a direction perpendicular to the width limiting strip, and the lower roller body 105 is located in the middle of the positioning slot 104. In this embodiment, three width limiting strips 103 are provided, and each lower roller body 105 passes through the positioning slots 104 of the three width limiting strips 103 at the same time. The lower roller bodies 105 are distributed at equal intervals, and the number of the lower roller bodies 105 is equal to the number of the positioning slots 104. The lower roller body 105 is provided to reduce the friction during the copper wire extrusion process so that the copper wire can be better transmitted out.

[0027] The clamping device 2 includes a lower clamping block 201, the bottom of which is fixedly connected to a clamping strip 202, the clamping strip 202 is located between the width limiting strips 103, a connecting bearing 203 is installed at the bottom of the clamping strip 202, and the connecting bearing 203 is coaxially connected to an upper clamping roller 204. After installation, the upper clamping roller 204 can rotate and approach the lower roller body 105.

[0028] A hinged ear 205 is installed on the top of the lower pressing block 201, and the hinged ear 205 is connected to the transmission device to drive the lower pressing block 201 to rise and fall. By setting equidistantly distributed width limiting strips 103 inside the lower mold box 101, multiple channels connecting the two copper wire inlets and outlets 102 on two opposite side walls are formed, and at the same time, a clamping strip 202 is fixedly connected to the bottom of the lower pressing block 201, so that the clamping strip 202 is inserted between the width limiting strips 103, and the hinged ear 205 is connected to the electric push rod or hydraulic rod, driving the lower pressing block 201 to adjust the height of the clamping strip 202 inside the lower mold box 101 to adjust the height of all wire pressing channels, thereby achieving the effect of improving the copper wire production efficiency.

[0029] The device itself can be used as a mold, and if the mold is placed between the lower roller body 105 and the upper pressure roller 204, the mold can be fixed between the lower roller body 105 and the upper pressure roller 204 by pressing down the clamping strip 202, and used as a clamping device for the mold.

[0030] The height of the width limiting strip 103 is greater than the height of the copper wire inlet and outlet 102, and the top of the positioning groove 104 does not exceed the top of the lower mold box 101. By raising the top of the width limiting strip 103 higher than the top of the copper wire inlet and outlet 102, the width limiting strip 103 can be fixed to the inner wall of the lower mold box 101, and the top of the width limiting strip 103 does not exceed the top of the lower mold box 101, so that the top of the width limiting strip 103 can support the bottom of the lower pressing block 201.

[0031] The spacing between the width limiting strips 103 and the spacing between the width limiting strips 103 and the inner wall of the lower mold box 101 are equal, forming a pressing channel. In this embodiment, there are 3 width limiting strips, which together with the inner wall of the lower mold box 101 form 4 pressing channels. By setting the spacing between the width limiting strips 103, the spacing between the channels formed by the width limiting strips 103 is equal. When producing copper wires, all the copper wires produced have the same specifications, and the adjustment of uniform specifications can be achieved by adjusting the pressing strips 202.

[0032] The outer surface of the lower pressing block 201 is completely in contact with the inner wall of the lower mold box 101, and the number and position of the upper pressing rollers 204 are equal to the number and position of the lower roller body 105. By making the outer surface of the lower pressing block 201 completely in contact with the inner wall of the lower mold box 101, the lower pressing block 201 is limited by the inner wall of the lower mold box 101 to avoid the lower pressing block 201 from shaking due to the gap. Once the lower pressing block 201 can shake, the spacing between the pressing strip 202 at the bottom of the lower pressing block 201 and the bottom of the lower mold box 101 will be different, resulting in inconsistent specifications of the produced copper wires.

[0033] The connecting bearing 203 is installed between the pressing strips 202, and the pressing strips 202 are located between the positioning grooves 104 and are blocked by the width limiting strips 103. The connecting bearing 203 is used to connect the upper pressing roller 204, and the connecting bearing 203 is arranged between the pressing strips 202, so that the connecting bearing 203 will not have an extrusion-shaped contact with the copper wire.

[0034] The bottom of the upper pressing roller 204 protrudes from the bottom of the pressing strip 202, and a groove is provided between the upper pressing rollers 204, and the groove is adapted to the position of the connecting bearing 203. When the upper pressing roller 204 protrudes from the bottom of the pressing strip 202, the upper pressing roller 204 can cooperate with the lower roller body 105 to press the copper wire, and the connecting bearing 203 is adapted to the groove on the surface of the upper pressing roller 204 for connection, which can prevent the connecting bearing 203 from protruding from the upper pressing roller 204.

[0035] When in use, multiple channels are formed by setting equally spaced width limiting strips 103 inside the lower mold box 101, and at the same time, a pressing strip 202 is fixedly connected to the bottom of the lower pressing block 201, so that the pressing strip 202 is inserted between the width limiting strips 103, and an electric push rod or a hydraulic rod is connected to the hinge ear 205 to drive the lower pressing block 201 to adjust the height of the pressing strip 202 inside the lower mold box 101 to adjust the height of all the wire pressing channels, thereby achieving the effect of improving the production efficiency of copper wires;

[0036] By making the outer surface of the lower pressing block 201 completely fit with the inner wall of the lower mold box 101, a positioning groove 104 is opened on the width limiting strip 103, and the upper pressing roller 204 can be raised and lowered through the positioning groove 104, and the position of the upper pressing roller 204 is limited. Therefore, when adjusting the bottom height of the clamping strip 202, a variety of limiting means can prevent the bottom of the clamping strip 202 from tilting and causing the copper wire size to be unqualified.
