Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-5 , including an extruder body 1, a support frame 9, which is arranged on one side of the discharge port of the extruder body 1, and a bracket is fixed on the side of the support frame 9 away from the extruder body 1, and a motor is installed on the bracket; a transmission screw rod 10 is arranged above the support frame 9, and one end is connected to the transmission end of the motor installed on the support frame 9; a second transmission block 11 is sleeved on the outer ring of the transmission screw rod 10, and a support rod is fixed at the bottom; a clamping device is fixed at the bottom of the support rod of the second transmission block 11; an opening and closing device is installed on the side of the clamping device.

[0027] The clamping device includes a connecting frame 12, a transmission rod 13, a connecting block 14, a control rod 15 and a clamping rod 16. The connecting frame 12 is fixed below the bottom strut of the second transmission block 11. The connecting frame 12 is generally in an inverted U shape. Extension plates extending inward are fixed at the bottoms of both sides, and mounting grooves are formed in the middle of the extension plates. An activity hole is formed in one side of the connecting frame 12. One end of the transmission rod 13 is installed in the mounting groove formed in the connecting frame 12 through an activity shaft. The connecting block 14 is located inside the connecting frame 12. The connecting block 14 is in a convex shape, and mounting grooves are formed at both the top and the bottom. The end of the transmission rod 13 away from the connecting frame 12 is connected to the bottom of the connecting block 14 through an activity shaft. One end of the control rod 15 is connected to the top of the connecting block 14 and passes through the activity hole formed in the side wall of the connecting frame 12 in the middle. A limiting shaft is arranged in the activity hole. An activity hole is formed in the control rod 15 corresponding to the position of the limiting shaft. The limiting shaft is inserted into the activity hole formed in the control rod 15 to limit the activity range of the middle section of the control rod 15. The clamping rods 16 are installed on both sides of the bottom of the connecting frame 12, and one end of the top of the clamping rod 16 is connected to the transmission rod 13 through an activity shaft. The position of the clamping rod 16 at the bottom of the extension plate of the connecting frame 12 is connected to the connecting frame 12 through a rotating shaft. The up and down movement of the connecting block 14 is controlled by the movement of the control rod 15. When the end of the control rod 15 away from the connecting block 14 moves downward, the end of the control rod 15 close to the connecting block 14 is lifted by the limiting shaft, and at the same time, the connecting block 14 is driven to move upward. When the connecting block 14 moves, it pulls the transmission rod 13, and the transmission rod 13 drives the clamping rods 16 to tighten inward through the activity shaft, so as to realize the clamping of the copper rod. Then, the second transmission block 11 is driven through the guiding groove 20, so that the whole clamping device moves together to realize the pulling work of the copper rod. When the end of the control rod 15 away from the connecting block 14 moves upward, the end of the control rod 15 close to the connecting block 14 descends, and the connecting block 14 drives the transmission rods 13 to move away from each other, so that the transmission rods 13 drive the clamping rods 16 to move away from each other, and the clamping rods 16 release the clamped copper rod.

[0028] The opening and closing device includes a fixed plate 17, a compression spring 18, a movable rod 19 and a guide groove 20, wherein the fixed plate 17 is fixed to the outer wall of one side of the connecting frame 12 close to the control rod 15, and the fixed plate 17 is located on both sides of the movable hole opened by the connecting frame 12, a mounting hole is opened on the side of the fixed plate 17 close to the control rod 15, and a compression spring 18 is installed in the mounting hole, a movable rod 19 is arranged between the compression spring 18 and the control rod 15, and a spherical block is fixed on one end of the movable rod 19 close to the control rod 15, and the top or bottom of the control rod 15 is restricted by the movable rod 19, a guide groove 20 is arranged on the side of the support frame 9 close to the control rod 15, a downward inclined surface is arranged on the side of the guide groove 20 close to the extruder body 1, and an upward inclined surface is arranged on the side of the guide groove 20 away from the extruder body 1, when the control rod 15 is driven by the second transmission block 11 to move to the downward inclined surface of the guide groove 20, the top part of the control rod 15 starts to move downward along the downward inclined surface, and the control rod 15 presses the copper rod when moving. The movable rod 19 is clamped and compressed from the top side of the control rod 15 into the mounting hole of the fixed plate 17 during the downward movement of the control rod 15. When the control rod 15 is moved to the bottom by the descending inclined surface of the guide groove 20, the positions of the control rod 15 and the movable rod 19 are staggered, and the movable rod 19 pops out from the mounting hole and is located on the top side of the control rod 15 to restrict the movement of the control rod 15 to prevent the copper rod from falling off when the clamping device is pulling the copper rod. When the control rod 15 is driven by the second transmission block 11 to move to the ascending inclined surface of the guide groove 20, the bottom of the control rod 15 is lifted upward along the ascending inclined surface. During the lifting process of the control rod 15, the clamping rods 16 move away from each other to release the copper rod. When the ascending inclined surface of the control rod 15 is at the top, the movable rod 19 changes from the top of the control rod 15 to the bottom of the control rod 15 to continue to restrict the control rod 15 so that the clamping device directly clamps the copper rod when it moves to the side of the extruder body 1.

[0029] A heat preservation box 2 is arranged on the side of the extruder body 1 away from the support frame 9, and a movable space is reserved in the middle of the top of the heat preservation box 2. A transmission roller 3 is installed inside the heat preservation box 2. When the copper rod raw material is being extruded, the remaining copper rod raw material can maintain the temperature inside the heat preservation box 2 to prevent the raw material temperature from decreasing and maintain the plasticity of the raw material. A transmission screw 4 is arranged on the top of the transmission roller 3. The transmission screw 4 is located above the movable space reserved in the heat preservation box 2. The end of the transmission screw 4 away from the support frame 9 is connected to a motor. The outer surface of the transmission screw 4 is installed with a first transmission block 5. The transmission screw 4 is driven by the motor to rotate, so that the first transmission block 5 moves on the transmission screw 4.

[0030] A movable shaft is provided at the bottom of the first transmission block 5, and a push rod 6 is installed on the outside of the movable shaft. When the copper rod is extruded, the motor drives the push rod 6 to move through the first transmission block 5, so that the push rod 6 pushes the copper rod raw material above the transmission roller 3 to move toward the extruder body 1. With the continuous reservation of the push rod 6, the copper rod raw material is gradually extruded by the extruder body 1. A tension spring 7 is connected between the first transmission block 5 and one side of the push rod 6. One end of the tension spring 7 is connected to the bottom of the first transmission block 5, and the other end is connected to the side wall of the push rod 6. A guide rod 8 is fixed on the top of the side of the insulation box 2 away from the extruder body 1. When the motor drives the first transmission block 5, the push rod 6 is pushed to the extruder body 1. When the movable block 5 moves to the side of the guide rod 8, the push rod 6 moves with the first transmission block 5, and the side of the push rod 6 is blocked by the guide rod 8. When the first transmission block 5 continues to move toward the motor, the push rod 6 starts to rotate around the movable axis, so that the bottom end of the push rod 6 is gradually lifted. When the push rod 6 is lifted, it is convenient for the copper rod raw material to enter the insulation box 2. By arranging the push rod 6 above the transmission roller 3, the space occupied by the machine is further reduced. When the push rod 6 is moved toward the extruder body 1 by the motor through the first transmission block 5, the push rod 6 is reset by the tension of the tension spring 7, and the reset push rod 6 continues to push the copper rod raw material.

[0031] Working principle: the copper rod raw material is sent from the side of the insulation box 2 away from the extruder body 1 to the top of the transmission roller 3, and the transmission screw 4 is driven by the motor to rotate, so that the transmission screw 4 drives the push rod 6 to push the copper rod raw material to move toward the extruder body 1. After the copper rod raw material is extruded by the extruder body 1, it falls on the surface of the support frame 9, and the motor is started to move the second transmission block 11 to the side of the extruder body 1. When the second transmission block 11 drives the clamping device to move to one side of the extruder body 1, the control rod 15 moves downward along the downward inclined surface of the guide groove 20, so that the clamping device clamps the copper rod, and then the second transmission block 11 is moved away from the extruder body 1 by the motor to pull the copper rod to complete the pulling work of the copper rod. When the clamping device that has completed the pulling work moves to the upward inclined surface of the guide groove 20, the clamping rods 16 move away from each other to release the clamped copper rod, so that the second transmission block 11 drives the clamping device to return to the side of the extruder body 1 again to clamp and pull the new copper rod.
