Description

Technical Field

[0001] The utility model relates to the technical field of wire material processing, in particular to a wire material heating and straightening device. Background Art

[0002] After the wire is produced, in order to facilitate handling and storage, and to protect the wire, it will be bent and wound into a reel to improve transportation efficiency.

[0003] When the wire is subsequently reprocessed, the bending angle and curve radius of the wire are uncertain, the shape is complex, and the length is difficult to control. Therefore, the bent wire needs to be straightened to ensure the processing quality and effect. Due to the stress and memory of the wire material, the wire tends to maintain a bent shape. Even if the bent wire is squeezed and stretched multiple times, the wire will still try to restore its original shape, making it difficult to completely straighten it. The straightening efficiency is low and the straightening effect is poor, which affects the subsequent processing effect of the wire. Utility Model Content

[0027] Figure 1 The three-dimensional structure diagram of the wire heating and straightening device provided by the embodiment of the utility model is shown. Figure 2 FIG. 1 shows a cross-sectional structural diagram of the heating mechanism 3 in the wire heating and straightening device provided in the embodiment of the utility model. Please refer to FIG. Figure 1 and Figure 2The wire heating and straightening device comprises a heating mechanism 3, wherein the heating mechanism 3 is provided with a wire hole 38 and a hot air cavity 35 connected to the wire hole 38, wherein the wire hole 38 is provided with an annular hot air groove 39 circumferentially, wherein the hot air cavity 35 is circumferentially connected to the wire hole 38 through the hot air groove 39, and the hot air groove 39 is arranged so that its air outlet direction is offset toward the outlet direction of the wire hole 38. A hot air pipe 4, wherein the hot air pipe 4 is connected to the hot air cavity 35. A first straightening mechanism 6, wherein the first straightening mechanism 6 is arranged along the outlet direction of the wire hole 38. Specifically, the hot air is circumferentially passed into the wire hole 38 to ensure that the wire in the wire hole 38 is completely and evenly heated to ensure the heating effect. The hot air groove 39 is arranged near the entrance of the wire hole 38 to facilitate filling the entire section of the wire hole 38 with hot air to ensure the heating effect of the wire. Before the wire is straightened by the straightening mechanism, the wire is first heated by hot air. Heating improves the plasticity and deformation ability of the material, and eliminates the shape memory effect and internal stress of the material. The heated wire is easier to straighten, greatly improving the efficiency and effect of wire straightening. The direction of the hot air is consistent with the moving direction of the wire, allowing the hot air to adhere to the surface of the wire to fully heat the wire, ensuring that the wire is heated to a temperature suitable for straightening.

[0028] The specific structure of the exhaust hole 12 and the bottom plate 1 is described below:

[0029] Please refer to Figure 1 and Figure 2 , the heating mechanism 3 is also provided with an exhaust hole 12, which is connected to the wire hole 38 and the outside of the heating mechanism 3. The exhaust hole 12 is arranged near the outlet of the wire hole 38, and the hot air first fills the wire hole 38 and then is discharged along the exhaust hole 12. The apertures at the outlet and inlet of the wire hole 38 are small, which reduces the amount of hot air overflow and ensures that most of the hot air is discharged from the exhaust hole 12. It also includes a bottom plate 1, the heating mechanism 3 and the first straightening mechanism 6 are arranged above the bottom plate 1, and the shell 2 is arranged below the bottom plate 1, and the shell 2 covers the hot air pipe 4. The shell 2 protects the hot air pipe 4 and the cold air pipe 5, and at the same time makes the appearance of the whole device more beautiful. The exhaust hole 12 passes through the bottom plate 1, connecting the wire hole 38 and the inside of the shell 2. The hot air discharged from the exhaust port flows into the cavity 21, which assists in heating the gas in the hot air pipe 4, makes full use of the heat, is green and environmentally friendly, and ensures heating efficiency. A fixing plate 11 is arranged below the bottom plate 1, and the hot air pipe 4 passes through the fixing plate 11. The fixing plate 11 enhances the stability of the hot air duct 4 and the cold air duct 5 and reduces their shaking.

[0030] The specific structure of the heating mechanism 3 is described below:

[0031] Please refer to Figure 1 and Figure 2, a cold air cavity 32 is also provided on the heating mechanism 3, and the cold air cavity 32 is connected to the wire hole 38, and the cold air cavity 32 is connected to the cold air pipe 5. When the machine is shut down, part of the wire stays in the heating mechanism 3. At this time, the hot air in the heating mechanism 3 will continue to heat the part of the wire, causing the wire to overheat, age or even damage the wire. The cold air cavity 32 can pass the cold air into the wire hole 38 at this time to reduce the temperature in the wire hole 38 and prevent the wire from being continuously heated. The heating mechanism 3 includes a first sleeve 31, a second sleeve 34, and a shell 37 sleeved on the first sleeve 31 and the second sleeve 34. The barrel holes on the first sleeve 31 and the second sleeve 34 are connected to form the wire hole 38, a hot air cavity 35 and a hot air groove 39 are formed between the first sleeve 31 and the second sleeve 34, and a cold air cavity 32 is formed between the shell 37 and the first sleeve 31. Specifically, a first extension portion 33 is provided on the first sleeve 31, and a conical second extension portion 36 is provided on the second sleeve 34. The first extension portion 33 and the second extension portion 36 cooperate to form a hot air chamber 35 and a hot air groove 39 between the first sleeve 31 and the second sleeve 34. The first extension portion 33 fits the shell 37, and because there is a height difference between the first extension portion 33 and the main body of the first sleeve 31, a cold air chamber 32 is formed between the first sleeve 31 and the shell 37. The cold air chamber 32 surrounds the first sleeve 31 and is circumferentially connected to the wire hole 38 to ensure the cooling effect on the wire hole 38, so as to quickly reduce the temperature in the wire hole 38 and prevent the wire material staying in the wire hole 38 from being heated and damaged.

[0032] The specific structures of the first straightening mechanism 6 and the second straightening mechanism 7 are described below:

[0033] Figure 3 The wire heating and straightening device provided by the embodiment of the utility model is shown in a partial enlarged view at A, please refer to Figure 3 The first straightening mechanism 6 comprises two parallel and staggered straightening wheels 61. The straightening wheels 61 have U-shaped grooves 62 on their surfaces, and the wire is squeezed and straightened between the two rows of straightening wheels 61.

[0034] The first straightening mechanism 6 includes a mounting plate 63 and an adjusting plate 66 slidably arranged on the mounting plate 63, a row of straightening wheels 61 are arranged on the mounting plate 63, and a row of straightening wheels 61 are arranged on the adjusting plate 66. A slide groove 64 is arranged on the mounting plate 63, and a limiting bolt 67 is inserted into the slide groove 64. The limiting bolt 67 is threadedly connected with a limiting nut 68, and the bolt portion of the limiting bolt 67 and the limiting nut 68 clamp the mounting plate 63 and the adjusting plate 66. An adjusting bolt 65 is also arranged on the mounting plate 63, and the screw rod of the adjusting bolt 65 is against the screw rod of the limiting bolt 67. By screwing the adjusting bolt 65, the distance between the two rows of straightening wheels 61 can be adjusted, thereby adjusting the straightening effect. A second straightening mechanism 7 is also included, and the second straightening mechanism 7 is arranged along the outlet direction of the outlet hole, connected to the first straightening mechanism 6, and the straightening wheel 61 in the first straightening mechanism 6 is perpendicular to the straightening wheel 61 in the second straightening mechanism 7. The heated wire is extruded and straightened from different directions to improve the straightening effect.

[0035] The specific working process of the utility model is as follows:

[0036] When straightening begins, the blower sends air into the hot air pipe 4. The air in the hot air pipe 4 is heated by the heating chamber 41 and flows into the hot air chamber 35, and then flows into the wire hole 38 along the hot air groove 39. After hot air is passed into the wire hole 38, the wire is continuously inserted along the wire feeding hole, and the wire in the wire feeding hole is continuously heated and softened, and then extends into the first straightening mechanism 6 and the second straightening mechanism 7 in turn, and is squeezed and straightened from different directions by the straightening wheel 61.

[0037] When work is suspended, the blower sends air into the cold air duct 5, and the unheated cold air passes through the cold air duct 5 into the wire hole 38, and after mixing with the hot air, flows into the cavity 21 along the exhaust hole 12, taking away the heat of the heating mechanism 3 to stop heating and cool the wire in the wire hole 38.

[0038] It can be seen that the above-mentioned heating and straightening device first heats the wire with hot air before the wire is straightened by the straightening mechanism. Heating improves the plasticity and deformation ability of the material, and eliminates the shape memory effect and internal stress of the material. The heated wire is easier to straighten, which greatly improves the efficiency and effect of wire straightening. The direction of the hot air is consistent with the moving direction of the wire, so that the hot air adheres to the surface of the wire to fully heat the wire, ensuring that the wire is heated to a temperature suitable for straightening.

[0039] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0040] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
