Description

Technical Field

[0001] This utility model relates to the technical field of copper wire drawing devices, specifically a copper rod wire drawing device. Background Technology

[0002] Copper rod drawing is a technical processing method that forces a copper rod through a die under external force, compressing its cross-sectional area and obtaining the required cross-sectional shape and size. Copper rod drawing mainly consists of a die, a fixture, and a traction mechanism.

[0003] However, during copper rod drawing, the copper rod needs to be manually inserted into the drawing die first, and then clamped at one end of the copper rod using a fixture. The entire process requires manual insertion of the copper rod through the drawing die, resulting in uneven drawing at one end of the die and is time-consuming and labor-intensive. Furthermore, since only the fixture provides the force for the copper rod to pass through the die during drawing, the clamping force must be large to prevent the copper rod from detaching, which can damage the clamped surface of the copper rod. Therefore, we propose a copper rod drawing device. Utility Model Content

[0004] The purpose of this utility model is to provide a copper rod drawing device, which solves the problems of copper rods needing to be manually passed through the drawing die, uneven drawing at one end of the copper rod, and excessive clamping force caused by only the clamp providing the pulling force, resulting in defects on the surface of the copper rod.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A copper rod drawing device includes a frame, on which a feeding mechanism is provided. The feeding mechanism includes a feeding rack, on which a placement rack is fixedly installed. Two sprockets are rotatably mounted on the outer surface of the feeding rack, and a chain is installed between the two sprockets. An extrusion plate is fixedly installed on the chain.

[0007] Preferably, the feeding rack has an inclined surface and a notch.

[0008] Preferably, the chain is provided with a clamping mechanism, the clamping mechanism includes a fixed rod, the fixed rod is fixedly connected to the chain, and a pressing block is slidably installed on the fixed rod.

[0009] Preferably, a protrusion is fixedly installed on the surface of the feeding rack, and the two ends of the protrusion are arc-shaped structures.

[0010] Preferably, the extrusion block has a movable groove that is adapted to the fixed rod.

[0011] Preferably, the fixing rod has an installation groove, and the top end of the installation groove is connected to the extrusion block by a spring.

[0012] Preferably, a movable frame is slidably mounted on the frame, a clamp is provided on the movable frame, a wire drawing die is provided on the frame, and a material leakage groove is provided on the frame.

[0013] By means of the above technical solution, this utility model provides a copper rod drawing device that has at least the following features:

[0014] Beneficial effects:

[0015] (1) By setting up a feeding rack, the copper rod enters the placement rack through the notch by gravity. The chain drives the extrusion plate to extrude the copper rod through the wire drawing die, which reduces manpower and improves the efficiency of wire drawing. At the same time, since the extrusion plate always provides pushing force to the copper rod, the clamping force of the clamp can be reduced, thereby reducing the wear on the surface of the copper rod and effectively improving the efficiency of copper rod wire drawing and the surface smoothness of the copper rod after wire drawing.

[0016] (2) By setting up a pressing mechanism, the copper rod is always pressed in the placement frame when drawing wire, which can effectively prevent the copper rod from leaving the placement frame box when passing through the drawing die and effectively ensure the stability of the copper rod displacement during the drawing process.

[0026] 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 some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1 - Figure 5 A copper rod drawing device includes a frame 1 with a material discharge groove 2 on one side. A movable frame 3 is slidably mounted on the frame 1, and a clamp 4 is mounted on the movable frame 3. A drawing die 5 is also fixedly mounted on the frame 1. The clamp 4 can clamp one end of the copper rod to fix it. The movable frame 3 drives the clamp 4 to move, allowing the copper rod to pass through the drawing die 5 and be drawn. After drawing, the clamp 4 is released, and the copper rod falls into the frame 1 under gravity and is discharged through the material discharge groove 2. The frame 1 is equipped with a feeding mechanism 6, which automatically passes the copper rod through the drawing die 5, saving manpower and making the passage of one end of the copper rod through the drawing die 5 more stable. In addition, it can provide a pushing force for drawing the copper rod, working together with the pulling force provided by the clamp 4, thereby reducing the clamping force required by the clamp 4 and avoiding defects on the surface of the copper rod caused by excessive clamping force.

[0028] Please see Figure 2 - Figure 4 The feeding mechanism 6 includes a feeding rack 61 for holding copper rods. The feeding rack 61 has an inclined surface 62 and a notch 63, the size of which is adapted to the size of the copper rod. The notch 63 connects to the bottom end of the inclined surface 62, allowing the copper rod inside the feeding rack 61 to slide down the inclined surface 62 to the notch 63 under gravity, and then pass through the notch 63 alone. A placement rack 64 is fixedly installed at the notch 63 on the feeding rack 61. The placement rack 64 has a "J"-shaped structure, so that the copper rod is caught in the inner arc of the "J"-shaped structure of the placement rack 64. The center of the inner arc of the "J"-shaped structure of the placement rack 64 is collinear with the center of the wire drawing die 5, allowing the copper rod to move linearly and pass through the wire drawing die 5.

[0029] Two sprockets 65 are rotatably mounted on the outer surface of the feeding rack 61. A chain 66 is installed between the two sprockets 65. The sprockets 65 are driven by a motor, which can drive the chain 66 for transmission. An extrusion plate 67 is fixedly installed on the chain 66. The bottom end of the extrusion plate 67 has a semi-circular structure. The extrusion plate 67 is adapted to the placement rack 64, so that when the extrusion plate 67 moves, it can push the copper rod to move along the placement rack 64, thereby allowing the copper rod to pass through the wire drawing die 5.

[0030] After a single copper rod has completely passed through the drawing die 5, the chain 66 continues to drive the extrusion plate 67 to move. At the same time, a new copper rod to be drawn is stuck in the placement frame 64 through the notch 63. The chain 66 continues to rotate until the extrusion plate 67 contacts the new copper rod to be drawn, thus achieving the function of continuous feeding.

[0031] Please see Figure 3 - Figure 5 A clamping mechanism 7 is provided on the chain 66 to clamp the copper rod inside the placement frame 64 during the wire drawing process, preventing the copper rod from detaching and deforming. The clamping mechanism 7 includes a fixing rod 71, which is fixedly connected to the chain 66. The fixing rod 71 is slidably connected to the pressing block 72 through a movable groove 73. The fixing rod 71 has a "T"-shaped structure and is adapted to the movable groove 73, so that the pressing block 72 can move along the fixing rod 71 without detaching from it. A mounting groove 74 is provided at the bottom end of the fixing rod 71. A spring is fixedly installed inside the mounting groove 74. The other end of the spring is connected to the pressing block 72. Under the elastic force of the spring, the bottom end of the movable groove 73 of the pressing block 72 contacts the bottom end of the fixing rod 71.

[0032] The surface of the feeding rack 61 is fixedly equipped with a protrusion 8. Both ends of the protrusion 8 are arc-shaped structures. The top two sides of the extrusion block 72 are arc-shaped structures, which makes the contact between the protrusion 8 and the extrusion block 72 and the extrusion block 72 more stable. At the same time, the bottom of the extrusion block 72 is semi-circular, which makes the contact between the extrusion block 72 and the copper rod more stable.

[0033] Please see Figure 3 There are multiple clamping mechanisms 7, which are arranged in an array, so that the copper rod is always in a clamped state when it is being drawn, making the drawing process more stable and uniform.

[0034] It should be noted that this invention is a copper rod drawing device. In use, an undrawn copper rod is placed inside the feeding rack 61. Under the influence of gravity, the copper rod slides down the inclined plane 62. A single copper rod enters the placement rack 64 through the notch 63. The motor is started, driving the sprocket 65 to work, which in turn drives the chain 66 to rotate. The chain 66 causes the fixed rod 71 and the pressing block 72 to shift until the pressing block 72 contacts the protrusion 8. The protrusion 8 presses against the pressing block 72, causing the pressing block 72 to move away from the fixed rod 71, thus allowing the pressing block 72 to... The chain 66 continues to move until the extrusion plate 67 contacts one end of the copper rod, thus pushing the copper rod and causing it to move along the placement frame 64. The copper rod passes through the drawing die 5 and is drawn into wire. After passing through the drawing die 5, the copper rod is clamped by the clamp 4. The movable frame 3 drives the clamp 4 to move, so that the copper rod is simultaneously subjected to the pulling force of the clamp 4 and the pushing force of the extrusion plate 67. This makes the copper rod more stable when passing through the drawing die 5 and drawing into wire, and the clamping force of the clamp 4 is relatively small, so as not to damage the surface of the copper rod.

[0035] After the copper rod is drawn, the clamp 4 is released, and the drawn copper rod falls into the frame 1 and is discharged along the material discharge groove 2. The movable frame 3 drives the clamp 4 to reset, and the chain 66 continues to rotate, pressing and positioning the copper rod that has fallen back into the placement frame 64 until the pressing plate 67 contacts the copper rod, thus realizing the continuous drawing operation of the copper rod.
