Description

Technical Field

[0001] The utility model belongs to the field of induction heating, and in particular relates to a length measuring structure for an alloy rod. Background Art

[0002] Titanium alloy rods are rod-shaped parts made of titanium alloy. They offer advantages such as light weight, high strength, and superior appearance, making them widely used in aviation and modern construction. However, before being processed into other workpieces, titanium alloy rods must undergo high-temperature treatment. Currently, this heating process typically involves a large, integrated inductor, slowly passing the workpiece through the inductor to heat it. This slow process, to ensure the heating temperature reaches the allowable value, results in a lengthy process and unsatisfactory heating results. Therefore, improvements to the heat treatment process for titanium alloy rods are urgently needed.

[0003] This application proposes a multi-stage heating zone solution. If the workpiece is heated at multiple levels, the length of the workpiece needs to be detected to arrange subsequent transportation and heating solutions. If the detection is performed by a sensor, on the one hand, the workpiece is too long and difficult to detect. On the other hand, there is a large amount of steam in the heating condition, which affects the detection. Therefore, mechanical measurement is preferably used. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] As attached Figure 1-2 As shown, a multi-level titanium alloy rod heating wire includes n heating zones, where n ≥ 2 and n is a natural number, and the n heating zones are arranged in series, and the tail end of the nth heating zone is connected to the unloading zone 4. Preferably, n is 3 or more. Taking the figure as an example, it includes a first-level heating zone 1, a second-level heating zone 2, and a third-level heating zone 3. Each heating zone is used to heat workpieces in different temperature ranges;

[0026] All heating zones and unloading zones 4 can be uniformly installed on a mounting foundation 5. Each heating zone includes a mounting frame 11. The bottom of the mounting frame 11 is fixed to the mounting foundation 5. Multiple transmission mechanisms and multiple sensors 10 are set on the mounting frame 11. The multiple transmission mechanisms and multiple sensors 10 are staggered in sequence. Preferably, as shown in the figure, each heating zone includes six groups of sensors 10 and seven groups of transmission mechanisms.

[0027] Further, as attached Figure 2 As shown, a position sensor 14 is provided on the side of the first transmission mechanism on the mounting frame 11; a position sensor 2 15 is provided on the side of the second transmission mechanism on the mounting frame 11. In detail, a plurality of brackets 3 13 are provided on one side of the mounting frame 11, and the position sensor 14 and the position sensor 2 15 are fixed on the brackets 3 13. The brackets 3 13 can be fixed to the mounting frame 11 or preferably fixed to the heat insulation baffle 42 mentioned later, as shown in the attached figure. Figure 5 As shown, a temperature probe 29 is set on the tail end of the mounting frame 11, especially on the side of the last three transmission mechanisms. The temperature probe 29 is fixed on the bracket 7 28. The bracket 7 28 is fixed to the mounting frame 11 or preferably fixed to the insulation baffle 42 mentioned later.

[0028] Furthermore, the sensor 10 itself is a prior art, which is heated by coil induction. The present invention does not involve any change to the principle. The sensor 10 includes a box body that encapsulates various components, and a through hole is provided in the middle of the box body for the workpiece to pass through. The box body itself is preferably also made of bakelite board material, and the bottom of the box body is fixedly connected to bakelite board 27, and both ends of bakelite board 27 extend out and are fixedly connected to the mounting frame 11.

[0029] Further, as attached Figure 6-8 As shown, an alloy rod heating wire transmission mechanism includes a roller 33, one end of which is connected to a driving mechanism, and the other end of which is provided with a water-cooling joint 30 that does not rotate with the rotation of the roller 33. The roller 33 is a hollow structure, and the water-cooling joint 30 is connected to the hollow structure of the roller 33 to form a water channel;

[0030] An annular groove 331 is formed inward at the end of the roller 33, and a rotating ring 332 is provided on the annular groove 331 to match the annular groove 331. The outer diameter of the rotating ring 332 is larger than the outer diameter of the roller 33. A connector 31 is provided on the outer end of the roller 33. The inner diameter of the connector 31 is larger than the outer diameter of the rotating ring 332. One end of the connector 31 extends inwardly to a limiting step 311. The inner diameter of the limiting step 311 is smaller than the outer diameter of the rotating ring 332. The other end of the connector 31 is fixedly connected to the water-cooling joint 30.

[0031] In detail, the connector 31 itself forms a flange surface, and the water-cooling joint 30 extends the flange surface toward the periphery. The two are fixedly connected via the flange surface, so that the water-cooling joint 30 and the rotating ring 332 form an axial limit for the connector 31 .

[0032] At least one of the connection head 31 and the rotating ring 332 or the rotating ring 332 and the annular groove 331 is clearance-fitted.

[0033] Furthermore, the water-cooling joint 30 includes a shell, which is provided with a water inlet 37 and a water outlet 38. A water pipe 301 is provided in the shell, and the water pipe 301 is connected to the water inlet 37. An annular cavity is formed between the outer wall of the water pipe 301 and the inner wall of the shell, and the annular cavity is connected to the water outlet 38.

[0034] The hollow structure of the roller 33 is a hollow tubular structure, which is connected to the annular cavity to form an outlet waterway 40, and the water pipe 301 extends into the hollow tubular structure to form an inlet waterway 39, so that a complete waterway is formed through a single joint. If the roller 33 is a hollow tubular structure with openings at both ends, a plug is set at the other end to seal the opening and reduce water leakage, that is, the second connector 34 in the figure.

[0035] Further, such as Figure 8 As shown in the figure, the roller 33 and the water-cooling joint 30 are rotatably matched through a stepped hole structure. Since it is difficult to achieve a perfect fit and continuous relative movement between the structure, if the roller 33 and the water-cooling joint 30 are in plane contact, more water leakage problems will occur. Although the stepped circular hole structure cannot eliminate the leakage problem, it can greatly reduce the leakage and does not affect the relative rotation between the two.

[0036] Further, such as Figure 9 As shown in the figure, both ends of the roller 33 are rotatably connected to a bearing seat 32, and a bakelite board 12 is set between the bearing seat 32 and the mounting frame 11 to reduce the leakage problem. One end of the roller 33 passes through the bearing seat 32 to connect to the output end of the reducer 35, and the input end of the reducer 35 is connected to the motor 36. The opposite inner sides of the two bearing seats 32 are fixedly connected to a heat insulation baffle 42, and the inner surface of the heat insulation baffle 42 is fixedly connected to a water-passing copper pipe 43. Both ends of the water-passing copper pipe 43 extend to both sides of the heat insulation baffle 42 and bend backward to form a water channel interface. The water-passing copper pipe 43 is preferably bypassed from above the roller 33 as shown in the figure, and the heat insulation baffle 42 is used to provide a certain degree of heat insulation protection for the original parts at the rear.

[0037] Furthermore, a support structure is provided on the roller 33 , and the outer diameter of the support structure decreases from both sides to the middle, so as to support the rod-shaped workpiece.

[0038] Further, as attached Figure 2-4As shown, a length measurement structure for an alloy rod includes a heating system, a roller mechanism is provided at the feed port of the heating system, the roller mechanism includes a roller 25, the roller 25 is connected to the encoder 9, and the roller mechanism is connected to a clamping mechanism, which is used to extend and retract the roller mechanism toward the working area of ​​the heating system.

[0039] The encoder 9 itself is a prior art, and is used to count the number of revolutions of the roller 25 , and determine the measured length by the number of revolutions and the circumference of the roller 25 .

[0040] The length of the workpiece is determined by mechanically measuring the number of revolutions of the roller 25 and the circumference of the roller 25 , and the pressing mechanism ensures effective contact between the roller 25 and the workpiece to prevent invalid measurement caused by uneven workpiece surface.

[0041] Furthermore, the heating system includes a mounting frame 11, the top of one end of the mounting frame 11 is fixedly connected to the door frame 47, the top of the door frame 47 is fixedly connected to the bracket 2 6 in the up and down directions, and a reinforcing rib plate is preferably provided between the bracket 2 6 and the door frame 47, and the bracket 2 6 is fixedly connected to the guide rail 18 along the length direction of the bracket 2 6, and the guide rail 18 slides with the slider 17, and the slider 17 is fixedly connected to the mounting plate 22, and the mounting plate 22 extends a cantilever frame 23 to one side, and the cantilever frame 23 is preferably an L-shaped plate, and the left side of the L-shaped plate is fixedly connected to the mounting plate 22, and the bottom of the L-shaped cantilever frame 23 is fixedly connected to the U-shaped frame 24 with an opening facing the workpiece, and a reinforcing rib plate is provided between the two plates of the L-shaped plate, and the lower opening of the U-shaped frame 24 is rotatably connected to the roller 25, and one end of the roller shaft of the roller 25 is connected to the encoder 9;

[0042] The clamping mechanism is a cylinder 19, the cylinder body of the cylinder 19 is fixedly connected to the bracket 26, and the output end of the cylinder 19 is connected to the mounting plate 22. The cylinder 19 itself has a certain force deformation capacity, and produces a small expansion and contraction according to the surface of the workpiece to prevent the pressure from being too large.

[0043] Furthermore, one end of the roller shaft of the roller 25 passes through the seat bearing 26 on the U-shaped frame 24 to connect to the encoder 9. The encoder 9 body is fixedly connected to the mounting plate 7, and the mounting plate 7 is fixedly connected to the U-shaped frame 24. A cover 8 is provided outside the encoder 9, and the cover 8 is fixedly connected to the U-shaped frame 24. The cover 8 has a baffle on at least one side close to the sensor 10 to block a certain amount of heat from the encoder 9.

[0044] Furthermore, the output end of the cylinder 19 is hinged to a U-shaped block 21, and the U-shaped block 21 is fixedly connected to the mounting plate 22. The purpose of this setting is that the roller 25 is close to the workpiece during measurement, generating friction in the transportation direction. This force acting on the output end of the cylinder 19 is already very small, but long-term use will still cause damage to the cylinder rod of the cylinder 19, so a hinged setting is made.

[0045] Furthermore, the second bracket 6 is fixedly connected to one end of the drag chain 16, and the other end of the drag chain 16 is fixedly connected to the second mounting plate 22 for protecting the power transmission and control lines.

[0046] Further, as attached Figure 9-10 As shown, the unloading area 4 includes a plurality of mounting frames 41 arranged in sequence, each mounting frame 41 is provided with a transmission mechanism, a mounting frame 3 44 is provided at the tail end of the unloading area 4, a distance sensor 45 is provided on the mounting frame 3 44, and the detection direction of the distance sensor 45 is arranged relative to the transportation direction of the transmission mechanism. A position sensor 3 46 is also provided on the mounting frame 3 44, one side of the mounting frame 3 44 is fixedly connected to an L-shaped rod, one side of the L-shaped rod is fixedly connected to the side of the mounting frame 3 44, and the other side of the L-shaped rod is parallel to the front end face of the mounting frame 3 44 and exceeds the front end face of the mounting frame 3 44 by 20-100 mm, and the position sensor 3 46 detects the front of the front end face of the mounting frame 3 44.

[0047] The working process of this utility model is as follows:

[0048] Before starting work, the heating wire is connected to cooling water.

[0049] The upper feeding device transports the workpiece 58 to the first-level heating zone 1. When the position sensor on the bracket 8 49 detects the arrival of the workpiece 48, the motor of the first-level heating zone 1 starts working. When the position sensor 14 detects the arrival of the workpiece, the cylinder 19 drives the roller 25 to press onto the workpiece so that the encoder 9 collects the length of the workpiece 48. At the same time, the sensor 10 of the first-level heating zone 1 starts working. The position sensor 2 15 is responsible for monitoring the position of the workpiece 48, and the temperature probe 29 is responsible for monitoring the temperature of the workpiece.

[0050] Driven by the transmission device, workpiece 48 reciprocates in primary heating zone 1. When workpiece 48 reaches the primary temperature, it is transported to secondary heating zone 2, where it undergoes the same heating process as in primary heating zone 1. When workpiece 48 reaches the secondary temperature, it is transported to tertiary heating zone 3, where it undergoes the same heating process as in primary heating zone 1. When workpiece 48 reaches the tertiary temperature, it is transported to unloading zone 4. Distance sensor 45 detects whether workpiece 48 has fully arrived in unloading zone 4. Position sensor 3 46 ensures that no workpiece 48 contacts mounting bracket 3 44. If so, an alarm will be triggered to alert staff.

[0051] After the workpiece 48 cools down, it is transferred to the next level equipment.

[0052] advantage:

[0053] The sensors are arranged in a dispersed array, which avoids the heat dissipation problem of large single sensors working for a long time, prolongs the service life of the heating wire, and also improves the processing efficiency of the workpiece;

[0054] The three-stage heating method of the workpiece improves the processing cycle of the workpiece;

[0055] Reciprocating heating avoids insufficient heating temperature of the part of the workpiece between adjacent sensors, and also makes the whole workpiece heated evenly, thus improving the heat treatment quality of the workpiece.

[0056] The above is only a preferred embodiment of the present invention. It should be pointed out that for those skilled in the art, several changes and improvements can be made without departing from the overall concept of the present invention, and these should also be regarded as the scope of protection of the present invention.
