Description

Technical Field

[0001] The utility model relates to the technical field of electric heating wire processing, in particular to an iron-chromium-aluminum electric heating alloy wire drawing device. Background Art

[0002] Iron-chromium-aluminum (FeCrA1) alloy wire is a material widely used in electric heating elements, offering excellent thermal stability, oxidation resistance, and electrical conductivity. The drawing unit is crucial in the production of FeCrA1 wire, transforming the extruded thick wire through multiple drawing steps into finer wires with a finer diameter and improved performance.

[0003] The Chinese patent with announcement number CN211161230U discloses a thick wire drawing mechanism for electric heating wire with stable connection. It is equipped with an installation frame and a first hydraulic cylinder fixedly arranged on both sides of the installation frame. When the two groups of first hydraulic cylinders are driven toward the middle at the same time, they can be fixed by the first clamp and the second clamp installed by threads at the output end. The first clamp and the second clamp are arranged in a "Y" shape, which can make the surface contacting the workpiece larger and ensure the firmness of the clamping. At the same time, the raised blocks arranged on the working surfaces of the first clamp and the second clamp can increase the friction between the clamp and the workpiece, making the clamping tighter. The first clamp and the second clamp connected by threads are convenient for disassembly and replacement. At the same time, a support rod and a support plate are provided to facilitate the support of one end of the workpiece after the cutting knife cuts.

[0004] However, the above technical solution has the following shortcomings: although the device solves the problem that the traditional drawing mechanism is relatively cumbersome in use by setting up the first clamp and the second clamp, since the first clamp and the second clamp are driven separately by two driving members, it is easy to cause uneven force on both sides of the workpiece, and then cause the side of the contact part between the frame and the workpiece to be subjected to greater force, resulting in obvious wear on the side of the workpiece that is under greater pressure and the frame during the drawing process, affecting the practicality and service life of the equipment. Utility Model Content

[0005] The purpose of the utility model is to address the problems existing in the background technology and propose an iron-chromium-aluminum electric heating alloy wire drawing device, which can not only quickly and tightly fix the end of the workpiece, but also avoid the disadvantage that the pressure deviation generated by the dual drive parts affects the processing quality of the workpiece.

[0006] The technical solution of the utility model is an iron-chromium-aluminum electric heating alloy wire drawing device, which includes a base and a clamping mechanism; a movable base and a frame are provided on the base; the clamping mechanism includes a mounting cylinder provided on the movable base, a fixed frame provided on the mounting cylinder, two rotating frames rotatably connected to the fixed frames, a fixed plate provided on the rotating frame, a first clamping plate and a second clamping plate respectively provided on the two fixed plates, a rotating shaft rotatably connected to the mounting cylinder and having a threaded portion, a movable block threadedly connected to the rotating shaft, a connecting plate whose two ends are respectively rotatably connected to the movable block and the rotating frame, and a driving assembly provided on the movable base.

[0007] Preferably, the driving assembly includes a motor arranged inside the moving base and a second gear drivingly connected to the motor. A first gear is coaxially arranged on the rotating shaft, and the first gear is meshed with the second gear.

[0008] Preferably, a mounting plate is provided on the mounting cylinder, and a plurality of fixing bolts threadedly connected to the movable seat are provided through the mounting plate.

[0009] Preferably, elastic anti-slip pads are provided on both the first and second clamping plates, the size of the second clamping plate is smaller than that of the first clamping plate, and the bending angle of the second clamping plate is greater than that of the first clamping plate.

[0010] Preferably, the movable seat is provided with a plurality of linearly distributed rollers, and the base is provided with grooves for the rollers to roll and connect.

[0011] Preferably, a cutting mechanism is provided on the frame, and the cutting mechanism includes a first cylinder and a second cylinder provided on the frame, and a first cutting knife and a second cutting knife drivenly connected to the first cylinder and the second cylinder respectively.

[0012] Preferably, the blade of the first cutting knife is a concave structure, and the blade of the second cutting knife is a convex structure.

[0013] Preferably, a telescopic rod is provided on the base, and a support frame is provided on the telescopic rod.

[0014] Compared with the prior art, the present invention has the following beneficial technical effects:

[0015] 1. The utility model has a detachable clamping mechanism that can not only firmly clamp the ends of workpieces of different cross-sectional sizes, but also the single-drive member design avoids the disadvantage of force deviation caused by driving with two drive members, which causes the workpiece to be squeezed and rubbed away from the clamping mechanism, and has good practicality.

[0016] 2. The utility model can make the cross section of the workpiece relatively flat during the cutting process by designing the cutting blades to be concave and convex in the cutting mechanism, thereby avoiding the situation where the cross section of the workpiece is obviously skewed or uneven due to the pressure generated during unilateral cutting.

DETAILED DESCRIPTION

[0022] Example 1

[0023] like Figure 1-Figure 4 As shown, the present embodiment provides an iron-chromium-aluminum electric heating alloy wire drawing device, which includes a base 1 and a clamping mechanism; a movable seat 2 and a frame 18 are provided on the base 1.

[0024] like Figure 1-Figure 3 As shown, the clamping mechanism includes a mounting tube 3 arranged on the movable seat 2, a fixed frame 4 arranged on the mounting tube 3, two rotating frames 5 rotatably connected to the fixed frame 4, a fixed plate 6 arranged on the rotating frame 5, a first clamping plate 7 and a second clamping plate 8 respectively arranged on the two fixed plates 6, a rotating shaft 10 rotatably connected to the mounting tube 3 and having a threaded portion, a moving block 11 threadedly connected to the rotating shaft 10, a connecting plate 12 rotatably connected to the moving block 11 and the rotating frame 5 at both ends, and a driving assembly arranged on the movable seat 2. A mounting disk 16 is provided on the mounting tube 3, and a plurality of fixing bolts 17 threadedly connected to the moving seat 2 are provided through the mounting disk 16. The fixing bolts 17 and the mounting disk 16 are provided to realize convenient installation and disassembly of the clamping mechanism, thereby avoiding the integrated structure being unfavorable for subsequent equipment repair and maintenance.

[0025] The driving assembly includes a motor 14 arranged inside the moving base 2 and a second gear 15 driven by the motor 14. A first gear 13 is coaxially arranged on the rotating shaft 10. The first gear 13 is meshed with the second gear 15. Elastic anti-slip pads 9 are provided on the first splint 7 and the second splint 8. The size of the second splint 8 is smaller than that of the first splint 7 and the bending angle of the second splint 8 is greater than that of the first splint 7.

[0026] When the workpiece is to be processed, the workpiece is first passed through the frame 18 and the end thereof is located in the clamping position of the clamping mechanism. Then the motor 14 is started to drive the first gear 13 to mesh with the second gear 15 for transmission. The first gear 13 drives the rotating shaft 10 to rotate, and then the moving block 11 is screwed with the threaded portion of the rotating shaft 10 and moves along the axial direction of the rotating shaft 10. During the movement of the moving block 11, the connecting plate 12 will rotate, and then the two rotating frames 5 drive the first clamping plate 7 and the second clamping plate 8 to rotate relative to each other until the first clamping plate 7 and the second clamping plate 8 clamp the end of the workpiece. The size and bending angle of the first clamping plate 7 and the second clamping plate 8 are set, and the elastic anti-slip pad 9 enables the two clamping plates to firmly clamp workpieces of different sizes. There is only one motor 14 as a driving component, which avoids the disadvantage of the force deviation during the driving of the dual driving components causing the workpiece to be squeezed and rubbed away from the clamping mechanism, and has good practicality.

[0027] Example 2

[0028] like Figure 1 and Figure 4 As shown, the present embodiment proposes an iron-chromium-aluminum electric heating alloy wire drawing device. Compared with the first embodiment, in the present embodiment, a cutting mechanism is provided on the frame 18, and the cutting mechanism includes a first cylinder 19 and a second cylinder 21 provided on the frame 18, and a first cutting knife 20 and a second cutting knife 22 driven and connected to the first cylinder 19 and the second cylinder 21 respectively. The blade of the first cutting knife 20 is a concave structure, and the blade of the second cutting knife 22 is a convex structure.

[0029] In this embodiment, after the workpiece is pulled to the required length, the first cylinder 19 and the second cylinder 21 are started simultaneously to drive the first cutting knife 20 and the second cutting knife 22 to move respectively. The concave and convex design can enable the two cutting knives to make the cross-section of the workpiece relatively flat during the cutting process, avoiding the pressure generated during unilateral cutting that causes the cross-section of the workpiece to be obviously skewed or uneven.

[0030] Example 3

[0031] like Figure 1 and Figure 2As shown, this embodiment proposes an iron-chromium-aluminum electric heating alloy wire drawing device. Compared with the first embodiment, in this embodiment, a plurality of linearly distributed rollers 25 are provided on the movable seat 2, a groove 26 for the rollers 25 to be rolled and connected is provided on the base 1, a telescopic rod 23 is provided on the base 1, and a support frame 24 is provided on the telescopic rod 23.

[0032] In this embodiment, after the workpiece is clamped, the movable seat 2 is dragged by an external dragging device (not shown). During pulling, the provided roller 25 can reduce the friction between the movable seat 2 and the base 1, thereby reducing the load of the dragging device. At the same time, the telescopic rod 23 and the support frame 24 provided in conjunction with each other can support the pulled workpiece, thereby preventing the workpiece from falling directly onto the base 1 during cutting.

[0033] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the purpose of the present invention.
