Description

Technical Field

[0001] The utility model belongs to the technical field of metal bar production equipment, and particularly relates to a device for precise heating of a bar by pulse current assistance. Background Art

[0002] The material forming and processing industry is an important part of the manufacturing industry, and material forming and processing technology is also an important part of advanced manufacturing technology. It is also widely used in the production process of wire and bar preparation. In the production process of wire and bar, in order to reduce its internal stress, pulse current assisted precision heating devices are generally used to uniformly heat the wires and bars to improve the quality of the wires and bars.

[0003] After searching, the publication number CN220926877U, application date 2023.03.30 discloses a wire and rod pulse current assisted heating and post-processing equipment, including clamping rollers, conductive wheels, conductive wheel brackets, hydraulic clamping mechanisms, pulse current generating and power-on devices, the conductive roller brackets have several groups of conductive wheels built in, and each group of conductive wheels is separated by an insulating block. The conductive wheel brackets correspond to each pair of conductive wheels and are provided with power-on interfaces to facilitate the introduction of pulse current. The outer side of the conductive wheel bracket is connected to the hydraulic cylinder through a hinge to achieve the purpose of clamping the wire and rod with the conductive wheel to achieve uniform power supply, thereby reducing the residual stress of the wire and rod, improving the matrix structure, and improving the comprehensive performance.

[0004] However, it still has the following disadvantages in actual use:

[0006] 2. The above-mentioned wire rod pulse current assisted heating and post-processing equipment heats the rod through the conductive wheels fixed on both sides when in use.

To this end, we provide a device for precise heating of rods assisted by pulse current to solve the above problems. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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. Specific embodiment 1

[0035] See also Figures 1 to 5 The utility model is a device for precise heating of a rod material with pulse current assistance, comprising a base 1 and a circular frame 103 mounted on the upper surface thereof, a rotating groove 101 is arranged at the center position of the upper surface of the base 1, a rod material body 106 is placed at the inner center position of the circular frame 103, U-shaped frames 105 are arranged on both sides of the outer wall of the rod material body 106, an adjusting component 2 is arranged inside the U-shaped frame 105; the adjusting component 2 comprises a servo motor 201 and an active disk 201a mounted on its output shaft, and a driven disk 202a is arranged on one side of the active disk 201a.

[0036] Specifically, auxiliary rollers 102 are evenly spaced and rotated inside the rotating groove 101 along the circumferential direction, fixed plates 104 are installed on the inner walls of both sides of the circular frame 103, and electric push rods 104a are installed on the front and rear ends of the outer wall of the fixed plate 104. The telescopic ends of the electric push rods 104a are installed on the front and rear ends of the outer wall of the U-shaped frame 105. The gears on the outer wall of the active disk 201a are meshed and connected with the gears on the outer wall of the driven disk 202a. The center position of the rear end surface of the driven disk 202a is installed with an adjusting shaft 202. The adjusting shaft 202 The rear end of 02 passes through the bearing on one side of the front end face of the U-shaped frame 105 and is connected to the bearing on one side of the rear end face inside the U-shaped frame 105. A rotating cylinder 203 is sleeved on the outer side of the outer wall of the adjusting shaft 202. A connecting plate 204 is fixedly connected to the outer side of the outer wall of the rotating cylinder 203 at uniform intervals along the circumferential direction. Insulating blocks 204a are installed on the outer wall of the connecting plate 204 at uniform intervals from front to back. Conductive wheels 205 are installed on the outer wall of the connecting plate 204 at uniform intervals from front to back, and the insulating blocks 204a and the conductive wheels 205 are alternately arranged.

[0037] Furthermore, the auxiliary roller 102 assists the rotation of the circular frame 103, and the electric push rod 104a can be used to push the U-shaped frame 105 to move and adjust the position. The cross-section of the rotating groove 101 is an arc shape. Since the gears on the outer wall of the active disk 201a are meshed and connected with the gears on the outer wall of the driven disk 202a, the active disk 201a will drive the driven disk 202a to rotate when it rotates. The rotation of the driven disk 202a can rotate the adjustment shaft 202 on its inner wall and the rotating drum 203 on its outer wall. Four connecting plates 204 are provided, and each connecting plate 204 is provided with a conductive wheel 205 of different sizes.

[0040] See also Figure 3 and Figure 6On the basis of the specific embodiment 1, what is different from the first embodiment is that: a circulating drive component 3 is provided, the circulating drive component 3 includes an asynchronous motor 301 and a driving wheel 301a installed on its output shaft, and driven wheels 303a are arranged on both sides above the driving wheel 301a, which solves the problem that the existing wire rod pulse current auxiliary heating and post-processing equipment heats the rod through the conductive wheels fixed on both sides when in use, and the heat in the middle of the conductive wheel in this way is higher than the heat on the upper and lower sides, so it will cause uneven heating of the outer walls around the rod, affecting the precise heating effect.

[0041] Specifically, the driving wheel 301a is connected to the outer walls of the driven wheels 303a on both sides above through the belt 302. A driving shaft 303 is installed at the center position of the rear end face of the driven wheel 303a. The other end of the driving shaft 303 passes through the bearing on the front end face of the rotating groove 101 and is connected to the bearing on the rear end face inside the rotating groove 101. A driving roller 303b is sleeved on the outer side of the outer wall of the driving shaft 303.

[0042] Furthermore, the operation of the asynchronous motor 301 can drive the driving wheel 301a to rotate, and under the action of the belt 302, the driven wheels 303a on the upper sides can rotate synchronously, and the driving shaft 303 and the driving roller 303b on the outer wall thereof can be rotated through the driven wheel 303a, and then the circular frame 103 can be driven to rotate under the action of the auxiliary roller 102.

[0043] The operation process of this embodiment is as follows: the rod body 106 to be heated is conveyed by the external pinch rollers, and the rod body 106 is placed in the conductive wheels 205 adjacent to each other on both sides, and then the rod body 106 is heated by using an external power supply, a wire, etc., and in the process of conveying and heating the rod body 106 by using the external pinch rollers and the conductive wheels 205, the asynchronous motor 301 is started, and the output shaft of the asynchronous motor 301 rotates to drive the driving wheel 301a to rotate. Since the outer wall of the driving wheel 301a is connected to the outer wall of the driven wheel 303a on both sides above through the belt 302, When the driving wheel 301a rotates, the driven wheels 303a on both sides above will be driven to rotate under the action of the belt 302. The rotation of the driven wheel 303a will rotate the driving shaft 303 on its inner wall, thereby rotating the driving roller 303b on the outer wall of the driving shaft 303, and driving the circular frame 103 above to rotate under the action of the auxiliary roller 102, thereby driving the conductive wheel 205 on the outer side of the outer wall of the rod body 106 to rotate, so as to achieve the purpose of uniformly rotating the middle part of the conductive wheel 205 to uniformly heat the outer wall of the rod body 106, thereby improving the precise heating effect of the rod body 106.
