Abstract
Description
Technical Field
[0001] The invention relates to the technical field of straightening equipment, and in particular to a metal wire straightening and cutting equipment. Background Art
[0002] Traditional wire straightening equipment usually uses rollers. Roller straightening mainly provides a straightening deflection for the wire. The motor drives the active pressure roller, which usually has two or three large active pressure wheels, and several small wheels as driven pressure wheels on the other side. The driven pressure wheel rotates through the friction of the wire. The disadvantages are: 1. It can only provide a straightening deflection in a certain direction for the wire, and cannot straighten the 360° circumference. It may not be able to offset the original curvature of the wire, causing the wire to still have warping problems after being straightened by the roller; 2. The position of the roller needs to be precisely adjusted for different materials and materials of different diameters, and the preparation work is complicated; 3. It often takes multiple tests to achieve the ideal effect; 4. The roller also needs a certain hardness (otherwise it is easy to wear and the roller needs to be replaced frequently), which will cause the surface of the wire to be easily scratched and the coating to wear, making the surface quality worse.

[0017] 1. Traditional wire straightening equipment usually uses a roller method. Roller straightening can only provide a straightening deflection in a certain direction for the wire, and cannot straighten a 360° circle. It may not be able to offset the original curvature of the wire, and it often requires multiple tests to achieve the desired effect. The present invention designs a wire straightening and cutting device, which rotates the wire and uses a sliding clamping device to compress and straighten the wire in all directions, that is, only one operation is required to straighten any curved wire, overcoming the shortcomings of traditional roller straightening. In addition, the preparation process is simple, and only the wire clamping force needs to be adjusted appropriately.
[0018] 2. Polyetheretherketone (PEEK) non-metallic material with lower hardness can be selected as the contact material of the metal wire.

[0019] 3. Use a photoelectric straightness detector or inspection plate to check whether the straightness of the wire meets the standard, and finally use a cutting knife combination device to cut the wire into the specified size.
[0020] 4. There is a clamping device for conveniently adjusting the wire clamping force, and the appropriate wire clamping force can be obtained through simple operation.
[0021] 5. The upper blade can be fine-tuned in the horizontal direction through the fine-tuning nut so that the clamping spring is compressed to push the clamping block to move toward the upper blade until the upper blade and the lower blade are clamped. The above principle is to rotate the fine-tuning nut to compress the clamping spring to generate elastic force, and the elastic force is a value that is linearly proportional to the compression length, so that the clamping force of the upper blade and the lower blade in the horizontal direction can be fine-tuned to adjust the gap between the upper blade and the lower blade, so as to achieve better cutting effect on the metal wire.

The angles between the upper and lower inclined surfaces of the cross sections of the small conical hole 721 and the large conical hole 722 are both 90°.
[0051] The contact surfaces of the upper clamping block 28 , the lower clamping block 34 , the hole entry lining ring 33 and the elastic plate 44 that are in contact with the metal wire are all made of polyetheretherketone (PEEK) material.
[0052] The working principle of the present invention is as follows: the method for straightening the metal wire is as follows: the servo motor 3 provides a constant speed, the metal wire is connected to the servo motor 3 through the elastic jacket 4, and continuously rotates, the clamping device 2 can slide through the metal wire on the slide rail 39, so that the metal wire is subjected to compression and deformation in various aspects, and finally the purpose of straightening is achieved. After straightening, the clamping device 2 of the metal wire is released, and the metal wire is passed through a photoelectric straightness detector or an inspection plate to check whether the straightness meets the standard, and finally the metal wire is cut into a specified size by a cutter assembly device 6.
[0053] In order to meet the requirements of all specified metal wires, an elastic jacket 4 is provided at the connection between the servo motor 3 and the metal wire to ensure that it is concentric with the main shaft of the servo motor 3 and can adjust the gap size of the clamping wire. The clamping device 2 has a replaceable wire inlet bushing 33, which has different specifications according to the different inner holes. By replacing the inlet bushing 33 of the corresponding size, metal wires of different specification series can be straightened. In order to prevent damage to the metal wire, all parts in contact with the metal wire are made of polyetheretherketone PEEK material.
[0054] The metal wire is driven by the servo motor 3 to rotate at high speed. The 360° circumferential straightening of the metal wire is achieved by two clamping devices 2 with sliding seats 36. The second clamping device 2 is mainly used to ensure that the metal wire coming out of the first clamping device 2 is on a horizontal straight line. At the same time, a second straightening is performed, which further improves the straightening accuracy. The clamping device 2 is as shown in FIG. Figure 6As shown. After the lifting pin 30 is lifted and rotated in a circle, it is clamped on the inverted L-shaped groove 31. At this time, the metal wire can be put in. Then the lifting pin 30 is rotated and lowered. The clamping spring 27 is in a naturally extended state. By manually rotating the rotating screw 22, the clamping spring 27 is compressed. The elastic force changes linearly with the compression length. The elastic force pushes the lower abutting gasket 26, thereby driving the clamping shaft 25 and the upper clamping block 28 fixed on the clamping shaft 25 to clamp the metal wire downward. By giving different compression lengths to the clamping spring 27, the appropriate clamping force can be adjusted for the metal wire. Since the upper clamping block 28 and the lower clamping block 34 are wearing parts, they are designed as simple flat surfaces and are easy to disassemble and assemble. The upper clamping block 28 can be replaced on the connecting disk of the clamping shaft 25 connected to it by only unscrewing the screws, and the lower clamping block 34 can be replaced by opening the end cover 35.
[0055] After the metal wire is straightened, it is necessary to test the straightness of the wire. It can be tested with a photoelectric straightness tester, or a simple test plate can be made according to the required accuracy for testing.
[0056] After the metal wire is tested and qualified, it needs to be cut according to the design requirements. Figure 8 The cutter assembly device 6 shown is used for cutting. By adjusting the position of the waist-shaped groove plate 703 on the stroke groove slide 70, the metal wire can be cut to a certain size. The upper and lower blades 67 are two V-shaped blades, the lower blade 67 is fixed, and the upper blade 65 can be fine-tuned in the horizontal direction by the fine-tuning nut 692 so that the clamping spring 693 is compressed and the clamping block 694 moves toward the upper blade 65 until the upper blade 65 and the lower blade 67 are clamped. The above principle is to rotate the fine-tuning nut 692 so that the clamping spring 693 is compressed to generate an elastic force, which is a value that is linearly proportional to the compression length, so that the horizontal clamping force of the upper blade 65 and the lower blade 67 can be fine-tuned to achieve a better cutting effect on the metal wire. When the metal wire is cut, the handle 62 moves downward in the vertical direction. Since the lower end of the handle 62 is provided with an eccentric portion 63, the connecting rod 64 will be driven to move downward. Since the upper blade 65 is fixed to the connecting rod 64, the upper blade 65 also moves downward. The upper blade 65 and the lower blade 67 are squeezed to cut the metal wire. The upper blade 65 is hung on the cutting seat by the tension spring 66. When the handle 62 is in the initial position and does not move downward, the tension spring 66 is also in the initial state, and is only affected by the gravity of the upper blade 65 and the connecting rod 64. When the handle 62 is forced to press the connecting rod 64 downward, the upper blade 65 drives the tension spring 66 to stretch and elastically deform. After the metal wire is cut, the handle 62 returns to the initial position, the tension spring 66 returns to the initial position, and the upper blade 65 also returns to the initial position. The cut metal wire, due to the action of gravity, will fall downward along the inclined surface of the 90° conical countersunk hole 72 into the receiving box 71. Since the object receiving box 71 is hung on the cutting seat, it is convenient to install and disassemble.
[0057] The control method of the electrical components involved above is controlled by the PLC electrical control box matched therewith, and the above control circuit can be realized by simple programming by technicians in this field, which belongs to the common knowledge in this field.
