Description

Technical Field

[0001] The present invention relates to the field of spoiler processing, and in particular to a spoiler processing method and device. Background Art

[0002] Turbulators, typically consisting of a series of twisted metal sheets or wires, are installed inside the heat exchanger's pipes. They work by altering the flow of fluids (usually two fluids at different temperatures) through the pipes, shifting the fluid's flow from a relatively smooth, laminar flow to a complex, turbulent flow. This turbulent flow enhances fluid mixing, increases the heat transfer area, and significantly improves heat exchange efficiency.

[0003] CN103639708B is a spiral bond processing equipment, specifically a complete set of spiral bond processing equipment, including a first roller machine, a trimming machine, a fixed roller, a baking device, a rotary stretching device, an automatic cutting machine and an automatic induction meter connected in sequence; wherein the rotary stretching device includes a turning machine for twisting the sheet, and the turning machine is composed of a rotating end and a sheet twisting part, and the sheet twisting part is composed of four pressing plates. The sheet is located between the four pressing plates, and driven by the rotating end, the sheet is twisted into a spiral shape. This technical solution can produce spiral bonds, but the early process is relatively complicated, and the length change caused by the rotation process is ignored during the rotary stretching process, so the formed rotary bond is unevenly formed. Summary of the Invention

[0004] In view of the deficiencies of the prior art, the present invention provides a spoiler processing method and device, which solves the problem of uneven forming of the rotating link mentioned in the above background technology.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a spoiler processing method and device, a spoiler processing method, comprising the following steps: S1, calculate the deformation, determine the tailstock movement, and determine the blanking length based on the cutting allowance, fixed clamping amount, and deformation; S2, clamping the material, fixing one end of the material and applying torque on the other end; S3, applying rotation to the material, and during the rotation, the tailstock moves in the direction of the rotation; S4, after the rotation is completed, the rotating parts drive the material to rotate; S5, cut at the finished length from one end of the rotating component.

[0006] Preferably, the deformation calculation formula in S1 is: , where R is the number of rotations, h is the thickness of the material, s is the lead of the spiral, and L is the length of the finished product. The blanking length = cutting allowance + fixed clamping amount + deformation amount + determined length.

[0007] Preferably, S21 is included: Without moving the tailstock, the rotating part first rotates 3 times.

[0008] Preferably, S31 is included: This includes the 3 turns of the rotating part when the tailstock does not move, the number of turns that the rotating part needs to complete, or the remaining 10 turns, and the length of the deformation of the tailstock during this process; Preferably, in S32, the tailstock remains fixed and the rotating component completes the remaining number of rotations.

[0009] Preferably, in S4, the number of revolutions of the rotating component is proportional to the length of the finished product, and the proportional coefficient is 750.

[0010] Preferably, the tailstock moving speed in S3 is proportional to the square of time.

[0011] A spoiler processing device includes a bed, one end of which is provided with a rotating component for driving material rotation, the other end of which is provided with a tailstock sliding along the bed, and a power mechanism above the bed that drives the tailstock to slide toward the rotating component.

[0012] Preferably, the rotating component includes a servo motor, which is fixedly mounted above the bed. A reducer is provided at the output end of the servo motor. A spindle box is fixedly mounted above the bed. The spindle box and the reducer are connected via a coupling. A chuck is provided at the output end of the spindle box.

[0013] Preferably, the power mechanism includes a linear guide rail, which is symmetrically installed at the tail end of the bed, and the tailstock is slidably connected above the linear guide rail. A servo motor is fixedly installed above the bed, and a lead shaft is fixedly installed at the output end of the servo motor, and the lead shaft is engaged with the tailstock.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The spoiler processing method performs segmented twisting during the twisting process of the spoiler. First, the spoiler is twisted for a number of turns in the tens digit, and the tailstock is moved during the twisting process. At this time, the twisting angle is large, and there is inertia in the long-term twisting. After stopping for a number of turns in the tens digit, it is easy to leave a margin for compensation, so that the spoiler after forming can be more uniform.

[0015] 2. The spoiler processing method is used to eliminate the elastic deformation caused by the twisting of the spoiler by actively rotating the spoiler a specified number of times during the twisting process, thereby ensuring that the material will not be elastically deformed and cause injury during the removal process.

[0016] 3. The spoiler processing device can slide the tailstock by setting a guide shaft controlled by a servo motor. By changing the sliding distance, it can achieve clamping of any length. During the torsional process, the sliding can be used to compensate for the torsional deformation length, thereby better realizing the processing of the spoiler. BRIEF DESCRIPTION OF THE DRAWINGS

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of such features.

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0021] like Figure 1-2 As shown, a spoiler processing method: The spoiler after plastic deformation is regarded as a spiral, and a single spiral part is equivalent to the length of the unfolded long side of the triangle.

[0022] The spoiler to be produced has a finished product length of L=4500mm, a thickness of d=1.2mm, a width of h=14.2mm, and a lead of s=110mm.

[0023] Based on the lead and the finished product length, it can be determined that 40.9 revolutions are required, and 41 revolutions are carried upwards.

[0024] Length of a single helix = ; Total spiral length = ; The length of the spiral part changes to 4600-4500=100mm; The total length of the blank is equal to the total length of the spiral + the clamping fixed length + the cutting allowance; The clamping fixed length is the length of the part to be welded later. This part is a fixed value. During the clamping process, the specified length is clamped in the chuck. In this embodiment, this part is 40mm. The length of the finished product of the cutting allowance is multiplied by the fixed coefficient 0.01, 4500*0.01=45mm; Therefore, the cutting length is 4600+40+45=4685mm, and the cutting and calculation are completed.

[0025] The position of the tailstock 3 is adjusted so that the tailstock 3 can just clamp the material with the rotating component 2 , and then a 40 mm portion of the material is clamped inside the chuck 204 , and the other end is clamped on the tailstock 3 .

[0026] The servo motor 201 is decelerated by the reducer 202 and drives the spindle in the spindle box 203 to rotate 3 circles. By rotating 3 circles first, the chuck 204 and the material can be clamped stably. The rotating component then continues to rotate the remaining number of turns. In this embodiment, the spindle needs to rotate 40.9 turns, which is rounded to the nearest ten, making it 40 turns. When the calculated number of turns is a positive ten, such as 50 turns, it rotates 40 turns first. During the 40 turns, the tailstock moves 100 mm. Since the initial radial contraction during the torsion process is small, the contraction rate increases as the torsion increases, which is approximately proportional to the time of flatness. During the movement, the movement speed gradually increases. The servo motor 402 drives the lead shaft 403 to rotate, thereby enabling the tailstock 3 to move along the linear guide rail 401.

[0027] Then, complete the remaining rotations; Then, the spoiler is rotated according to the finished product length and the proportional coefficient. The elastic rebound can be eliminated by the rotation. When the material is removed from the bed 1, the material rebounds and injures people, thereby completing the twisting of the spoiler.

[0028] Finally, the specified length is measured from the end of the chuck 204 according to the length of the finished product and the excess portion is cut off.

[0029] The device used includes a bed 1, one end of which is provided with a rotating part 2 for driving the material to rotate, the other end of the bed 1 is provided with a tailstock 3 sliding along the bed 1, and a power mechanism 4 is provided above the bed 1 to drive the tailstock 3 to slide toward the side of the rotating part 2.

[0030] The rotating component 2 includes a servo motor 201, which is fixedly installed above the bed 1. A reducer 202 is provided at the output end of the servo motor 201. A spindle box 203 is fixedly installed above the bed 1. The spindle box 203 and the reducer 202 are connected by a coupling. A chuck 204 is provided at the output end of the spindle box 203.

[0031] The power mechanism 4 includes a linear guide rail 401, which is symmetrically installed at the tail end of the bed 1. The tailstock 3 is slidably connected above the linear guide rail 401. A servo motor 402 is fixedly installed above the bed 1. A lead shaft 403 is fixedly installed at the output end of the servo motor 402, and the lead shaft 403 is engaged with the tailstock 3.
