[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0032] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0033] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the meaning of "and / or" throughout the text includes three parallel solutions; for example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied. Furthermore, "multiple" refers to two or more. Moreover, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent.

[0034] See Figures 1 to 5 This utility model discloses a copper material processing extrusion device, including symmetrically arranged side frames 1, a crankshaft 2 between the side frames 1, a cam 3 on the crankshaft 2, a pressure plate 4 that can be lifted and pressed down on the cam 3, and a base plate 6 below the pressure plate 4; four spring pins 8 are installed on both the pressure plate 4 and the base plate 6.

[0035] A convex diaphragm 16 is mounted below the pressure plate 4 via a spring pin 8;

[0036] A concave membrane 17 is mounted on the top of the base plate 6 via a spring pin 8.

[0037] Working principle

[0038] When extruding copper, the appropriate die should be changed according to the shape of the copper.

[0039] When replacing, pull out all the spring pins and use the clips on the spring pins to lock the spring pins and remove the mold.

[0040] After installing the new die, release the spring pin to tighten the newly installed die pin.

[0041] Positioning pins are provided at the center of each die, which facilitates the positioning of the die and installation, and prevents the die from rotating during extrusion and causing errors.

[0042] In some embodiments, see Figure 2 As shown, the bottom of the pressure plate 4 is provided with four limiting optical axes 5, which are movably embedded in the base plate 6. The optical axes are used to limit the downward pressing trajectory of the pressure plate and prevent the punch from being pressed out of place.

[0043] In some embodiments, see Figure 2 As shown, limiting blocks 10 are provided on both sides of the pressure plate 4;

[0044] The side frame 1 is equipped with a limiting rail 11 that is compatible with the limiting block 10;

[0045] The limiting block 10 is slidably embedded in the limiting rail 11. Both the limiting block and the limiting rail are used to limit the displacement of the pressing block and prevent the pressing block from being pressed out of place.

[0046] In some embodiments, see Figure 3 and 4 As shown, both the pressure plate 4 and the base plate 6 are provided with positioning posts 15 with rectangular cross sections;

[0047] The convex membrane 16 and concave membrane 17 are provided with positioning holes that are adapted to the positioning post 15;

[0048] The convex membrane 16 and the concave membrane 17 are also fitted into the positioning hole.

[0049] In some embodiments, see Figure 4 As shown, the side frame 1 is fixed to the base frame 9 at its bottom. A pad 7 is placed under the base plate 6 on the base frame 9. The pad 7 has a shaft hole located below the limiting optical axis 5, and the diameter of the shaft hole is larger than the diameter of the limiting optical axis 5. The pad is used to support the mold when the pressing height is insufficient, and then it is used in conjunction with the extrusion device. The specific height can be determined according to the pressing mold height during use and is not particularly limited.

[0050] In some embodiments, see Figure 1and 2 As shown, a driven pulley 12 is mounted on one side of the crankshaft 2. The driven pulley 12 is connected to a drive pulley 13 via a transmission belt. The drive pulley 13 is mounted on a motor via a coupling. The motor is mounted on the side frame 1. The motor is a speed-regulating motor. When in use, the motor is started, which drives the drive pulley to rotate. The drive pulley drives the driven pulley to rotate, which in turn drives the crankshaft to rotate. The crankshaft periodically presses down on the cam, which periodically presses down on the pressure plate. The pressure plate then extrudes the copper material through the convex diaphragm.

[0051] The intermittent downward pressure of the crankshaft cam on the pressure plate facilitates material feeding.

[0052] In some embodiments, see Figure 1 As shown, the top of the symmetrically arranged side frame 1 is equipped with a top plate 14.

[0053] In some embodiments, see Figure 1 As shown, the driven pulley 12 and the driving pulley 13 are also mounted on the side plate 1 via pulley brackets.

[0054] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
