Description

Technical Field

[0001] The utility model belongs to the technical field of spiral blade shaping, in particular to a spiral blade shaping device. Background Art

[0002] Spiral blades are widely used in various mechanical products. Due to their unique spiral structure, these blades can effectively remove chips during the machining process, reduce cutting resistance, and improve machining efficiency and surface quality.

[0003] In order to ensure that the spiral blade has sufficient hardness, toughness and wear resistance to adapt to the high-intensity processing environment, it is usually necessary to heat treat it to change the microstructure of the material and optimize the physical and mechanical properties.

[0004] During the heat treatment process, spiral blades are prone to deformation due to residual stresses from the spiraling process and fluctuations in heat treatment parameters. This deformation not only affects the blade's dimensional accuracy but can even lead to large-scale scrapping. This is especially true for spiral blades made from high-carbon alloy steel. While the steel has a high surface hardness after cold forming, the subsequent quenching process can lead to significant deformation due to drastic changes in internal structure and uneven thermal stress distribution, making manual correction difficult. This poses significant challenges to subsequent processing, assembly, and quality control. Utility Model Content

[0005] In view of the deficiencies in the prior art, the present invention provides a spiral blade shaping device, the purpose of which is to prevent the spiral blade from deforming during the heat treatment process.

[0006] In order to achieve the above-mentioned purpose, the utility model provides a spiral blade shaping device, including a shaping shaft, a first spiral plate, a second spiral plate, a pull rod, and a flange; the second spiral plate is wrapped around the outside of the shaping shaft and fixed to the outer surface of the shaping shaft; the first spiral plate is wrapped around the outside of the shaping shaft; the flange is fixed to one end of the shaping shaft; the pull rod is fixed to the first spiral plate, and the pull rod drives the first spiral plate to slide relative to the second spiral plate along the shaping shaft; a locking component is provided at one end of the pull rod passing through the flange, and the locking component applies tension to one end of the pull rod.

[0007] The second spiral plate is fixedly mounted outside the shaping shaft. Furthermore, a first spiral plate is slidably mounted outside the shaping shaft at a distance from the second spiral plate. The spiral blade is positioned between the first and second spiral plates and is clamped by the spiral plates on both sides to achieve shaping. A flange is fixedly mounted at one end of the shaping shaft. A pull rod is fixed to the first spiral plate, passing through the flange and secured to the flange via a locking component. The locking component acts on the pull rod, which applies a pulling force to the first spiral plate toward the flange, causing the first and second spiral plates to squeeze the spiral blade from both sides, thereby achieving the shaping effect and correcting deformation of the spiral blade during heat treatment.

[0008] Furthermore, one end of the pull rod is provided with a thread, the locking component is a nut, and the threaded end of the pull rod is matched with the nut.

[0009] The threaded end of the pull rod passes through the flange, and the nut applies tension to the pull rod by cooperating with the threaded end. Since the pull rod is fixedly connected to the first spiral plate, it also gives the first spiral plate tension to clamp the spiral blade, correcting the deformation of the spiral blade during heat treatment.

[0010] Furthermore, the number of spiral turns of the first spiral plate and the second spiral plate is 3-5 turns.

[0011] Furthermore, flange holes are arranged circumferentially on the flange, and each flange hole corresponds to a pull rod; there are multiple pull rods.

[0012] Multiple tie rods are tightened around each other, and the tension of each tie rod can be adjusted independently, so that the clamping force is evenly distributed on the first spiral plate, thereby effectively preventing the spiral blade from deforming during the heat treatment process.

[0013] Furthermore, there are five flange holes, and correspondingly there are five pull rods passing through the flange holes.

[0014] Furthermore, the second spiral plate is welded outside the shaping shaft; and the pull rod is welded to the first spiral plate.

[0015] Furthermore, welding nodes are arranged at equal intervals on the pull rod, welding nodes are arranged at equal intervals on the outer periphery of the second spiral plate, and the welding nodes of the pull rod are welded to the welding nodes of the second spiral plate.

[0016] Equally spaced welding nodes are provided on the pull rod, so that the second spiral plate is evenly stressed and provides the same extrusion force when clamping the spiral blade, thereby preventing the spiral blade from being deformed due to uneven stress at different parts.

[0017] Furthermore, the shaping shaft is a hollow tube or a solid cylinder.

[0018] Furthermore, a base is installed at the bottom of the shaping shaft; the base includes a connecting portion and a supporting portion, and the connecting portion is vertically arranged on the supporting portion.

[0019] The spiral blade shaping device is provided with bases at both ends of the bottom of the shaping shaft, respectively, for supporting the shaping shaft without affecting the sliding of the spiral blade.

[0020] Beneficial effects

[0021] 1. Deformation correction: The first and second spiral plates are designed to evenly clamp the spiral blade from both sides, which can correct the deformation of the spiral blade during heat treatment. This ensures the dimensional accuracy and shape stability of the blade.

[0022] 2. Improve efficiency: Since the deformation of the spiral blade during heat treatment can be corrected, rework or scrap caused by deformation can be reduced, thereby improving overall production efficiency and reducing production costs.

[0023] 3. Easy calibration: Through the use of multiple pull rods and nuts, the position of the first spiral plate and the force applied to different parts can be easily adjusted, so that the device can perform local calibration of the spiral blade. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The second spiral plate 22 is fixedly mounted on the outside of the shaping shaft 1. In addition, a first spiral plate 21 is slidably mounted on the outside of the shaping shaft 1 at a distance from the second spiral plate 22. The spiral blade is placed between the first spiral plate 21 and the second spiral plate 22 and is clamped by the spiral plates on both sides to achieve shaping. A flange 4 is fixedly mounted on one end of the shaping shaft 1. A pull rod 3 is fixed on the first spiral plate 21. The pull rod 3 passes through the flange and is fixed to the flange 4 by a locking component 42. Through the action of the locking component on the pull rod 3, the pull rod 3 applies a pulling force to the first spiral plate 21 to move toward the flange 4, so that the first spiral plate 21 and the second spiral plate 22 squeeze the spiral blade from both sides, thereby achieving the shaping effect and preventing the spiral blade from deforming during heat treatment.

[0032] One end of the tie rod 3 is threaded, and the locking member 42 is a nut, which is engaged with the threaded end of the tie rod 3. The threaded end of the tie rod 3 passes through the flange 4, and the nut cooperates with the threaded end to apply tension to the tie rod 3. Since the tie rod 3 is fixedly connected to the first spiral plate 21, it also applies tension to the first spiral plate 21 to clamp the spiral blade, preventing the spiral blade from deforming during heat treatment.

[0033] The number of spiral turns of the first spiral plate 21 and the second spiral plate 22 is 3-5.

[0034] Flange holes 41 are arranged circumferentially on the flange 4, each corresponding to a tie rod 3. Multiple tie rods 3 are provided. The tie rods 3 are tightened around the flange 4, and the tension of each tie rod 3 can be independently adjusted, which evenly distributes the clamping force on the first spiral plate 21, effectively preventing deformation of the spiral blade during heat treatment.

[0035] There are five flange holes 41 , and correspondingly there are five pull rods 3 passing through the flange holes 41 .

[0036] The second spiral plate 22 is welded to the outside of the shaping shaft 1; the tie rod 3 is welded to the first spiral plate 21. Equally spaced weld nodes are provided on the tie rod 3 to ensure uniform force on the second spiral plate 22 and provide uniform squeezing force when clamping the spiral blade, thereby preventing deformation of the spiral blade due to uneven force at different parts.

[0037] The shaped shaft 1 is a hollow tube or a solid cylinder.

[0038] The bottom of the shaping shaft 1 is equipped with a base 5; the base 5 includes a connecting portion 51 and a supporting portion 52, and the connecting portion 51 is vertically arranged on the supporting portion 52.
