[0003] The oxygen-free copper rod needs to be guided by a guide mechanism when it is being wound up. The existing guide mechanism has a guide hole on the guide mold. The size of the guide hole cannot be changed and cannot be applied to copper rods of different sizes.

In this way, the elastic effect of the elastic roller can adapt to oxygen-free copper rods of different sizes, and the roller can rotate to reduce friction on the surface of the copper rod. However, this structure also has disadvantages. The elastic force requirements of the elastic roller on each side of the oxygen-free copper rod are different. In particular, the bottom elastic roller needs to bear the gravity of the oxygen-free copper rod, and the required elastic force is the largest; and the elastic force requirements for oxygen-free copper rods of different sizes are also different.

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0030] refer to Figure 1 , an elastic force adjustment mechanism 6, comprising: a base 1; a telescopic rod 2, mounted on the base 1; a roller mechanism 3, having a fixed seat 31 mounted on the end of the telescopic rod 2 away from the base 1, and a movable roller 32 rotatably mounted on the fixed seat 31; a spring 4, sleeved on the telescopic rod 2, and one end of which abuts on the fixed seat 31; a movable abutting portion 5, which is guided and mounted on the telescopic rod 2, and the other end of the spring 4 abuts on the movable abutting portion 5; an adjustment mechanism 6, mounted on the base 1, to adjust the movable abutting portion 5 to rise and fall and thus control the elastic force of the spring 4. It can be understood that a U-shaped groove can be provided on the fixed seat 31, and the rotating shafts at both ends of the movable roller 32 are rotatably mounted in the groove; the guide matching of the movable abutting portion 5 and the telescopic rod 2 can adopt an axial hole guide matching structure, or a slide rail guide matching structure, etc. The movable abutting portion 5 and the fixed seat 31 abut against both ends of the spring 4, so that the movable roller 32 has elastic resistance when moving downward. The adjustment mechanism 6 can adopt a device with telescopic function, such as a cylinder, an electric push rod, etc. In this way, the compression amount of the spring 4 is adjusted by adjusting the position of the movable abutment member through the adjusting mechanism 6, thereby adjusting the elastic force of the movable roller 32.

[0031] In some embodiments, the axial direction of the movable roller 32 is perpendicular to the axial direction of the telescopic rod 2. It can be understood that the movable roller 32 is supported on the copper rod through the outer wall, so the elastic movement direction of the movable roller 32 needs to be perpendicular to the axial direction of the movable roller 32. Further, since the outer wall of the copper rod is in an arc shape, in order to make the movable roller 32 fit the copper rod and achieve a stable guiding effect, the outer wall of the movable roller 32 is set to be a concave arc shape.

[0032] In some embodiments, the movable abutment portion 5 is an annular structure, and then movably sleeved on the telescopic rod 2. An axial hole guide matching structure is adopted here, that is, the telescopic rod 2 is used as the axis and the movable abutment portion 5 is used as the axis. The structure is simple and the guidance is stable. The compression amount of the spring 4 can be adjusted by moving the movable abutment portion 5 up and down. Further, the adjustment mechanism 6 is a plurality of screws arranged around the movable abutment portion 5 as the center. The screw is vertically threaded and installed on the base 1, and the tail is against the movable abutment portion 5. It can be understood that in order to ensure the stability of the position of the movable abutment portion 5, at least three screws are used here. Due to the elastic force of the spring 4, the movable abutment portion 5 will be pressed down against the tail of the screw. Here, it is only necessary to rotate the screw forward and backward to adjust the movable abutment portion 5 up and down. The rotation of the screw can be manually rotated, or a motor can be installed to drive the rotation. Furthermore, the outer ring of the movable abutment portion 5 is provided with abutment blocks 51 corresponding to a plurality of screw rods, so that the screw rods abut against the abutment blocks 51 without damaging the movable abutment portion 5. Of course, in order to ensure that the screw rods do not deviate, a limiting hole can be provided on the abutment block 51, and the tail of the screw rod can be inserted into the limiting hole for limiting. Rotating parts such as bearings can also be installed on the abutment block 51, and the tail of the screw rod can be installed on the rotating part for rotational connection.

[0033] In some embodiments, a pressure sensor 7 is installed at the bottom of the fixed seat 31 and / or at the top of the movable abutment 5 to detect the elastic force of the spring 4. And / or the pressure sensor 7 can be installed at the bottom of the fixed seat 31 alone, at the top of the movable abutment 5 alone, or at the bottom of the fixed seat 31 and at the top of the movable abutment 5. In this way, the pressure sensor 7 can display the elastic force data through the display, and then observe the elastic force data according to the elastic force requirement of the movable roller 32 to adjust the elastic force, so as to achieve precise control of the elastic force of the movable roller 32, and further ensure the guiding stability of the copper rod.

[0034] refer to Figure 2 , an oxygen-free copper rod guide mechanism, comprising: a frame 8 and a plurality of elastic force adjustment mechanisms 6 mounted on the frame 8; a plurality of movable rollers 32 on the elastic force adjustment mechanisms point to a point and are arranged around the point as the center to form a through hole 9 for guiding the copper rod. It can be understood that, Figure 2Four elastic force adjustment mechanisms 6 are provided, and of course, two, three, five, etc. can also be provided. In this way, the elastic force adjustment mechanisms 6 in each direction can adjust the elastic force of the movable roller 32 according to the size of the copper rod and the direction position of the copper rod, so that the guidance of the copper rod is more stable. Further, the frame 8 is a frame-type structure in which a plurality of connecting plates 81 are connected end to end in sequence, and a reinforcing rod 82 is connected between each two adjacent connecting plates 81. The base 1 is installed on the connecting plate 81. Here, four elastic adjustment mechanisms 6 are provided, so four corresponding connecting plates 81 are also provided to form a square. The number of connecting plates 81 can be set according to the number of elastic adjustment structures. The reinforcing rod 82 and the two adjacent connecting plates 81 form a triangle to increase the firmness of the frame 8. The base 1 can be installed on the connecting plate 81 as a whole, or it can be fixed to the connecting plate 81 by connecting members such as bolts.

[0035] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
