Description

Technical Field

[0001] The utility model relates to the technical field of pipe fitting processing, and more specifically to an automatic device for solid solution of pipe fittings. Background Art

[0002] Solution treatment refers to a heat treatment process in which the alloy is heated to a high temperature single-phase region and maintained at a constant temperature so that the excess phase is fully dissolved into the solid solution and then rapidly cooled to obtain a supersaturated solid solution.

[0003] Stainless steel pipe processing companies are generally equipped with two types of equipment, namely, a solution furnace and a high-frequency induction solution device, when performing solution treatment on their products. The treatment of the solution furnace is mainly aimed at large quantities of pipe fittings, while the daily production of small and medium batches of pipe fittings still relies on traditional high-frequency induction solution equipment.

[0004] Many companies purchased high-frequency induction solution treatment equipment in the early days, which mainly relied on manual operation to complete solution treatment. The specific working process includes manually holding the pipe fittings, extending the pipe fittings into the induction area of ​​the induction coil, staying for a period of time, and then throwing the pipe fittings into the cooling pool. There are several situations that require special attention during the entire working process. First, the workers must have steady hands. When stainless steel pipe fittings come into contact with the induction coil, sparks will be emitted, posing a safety hazard. Second, to complete the solution treatment, the pipe fittings need to be heated to a certain temperature and maintained for a certain period of time. This is mainly judged by the workers' experience, so there may be problems of insufficient or too long time; insufficient time will not achieve the solution treatment effect, and too long time will cause overheating.

[0005] With the development of science and technology, the equipment for solid solution treatment of stainless steel pipe fittings has also been updated and upgraded, which can cope with the problems caused by the above-mentioned manual operation. However, the purchase of new equipment will greatly increase the cost of the enterprise. In order to save costs, some enterprises are still using old high-frequency induction solid solution equipment. Therefore, there is an urgent need for an auxiliary equipment that can continue to use the old equipment and solve the problems of manual operation safety and solid solution effect.

DETAILED DESCRIPTION

[0029] The technical solution of the utility model is further described in detail below through embodiments and in combination with the accompanying drawings, but the utility model is not limited to the following embodiments.

[0030] As a commonly used solid solution quenching device, the high-frequency induction solid solution device has been widely used in the quenching process of alloy materials and is an essential equipment in pipe production and processing enterprises. With the updating and iteration of technology, solid solution equipment with more comprehensive functions and superior performance has been successively used in production. Although the high-frequency induction solid solution equipment described in the utility model is a relatively old equipment, it can still meet the production needs of the factory in terms of basic functions. In addition, eliminating old equipment and purchasing new equipment will increase production costs. Therefore, the applicant has optimized and improved the equipment according to the situations encountered during use.

[0031] like Figure 1-5 As shown, an automatic equipment for dissolving pipe 70 includes a high-frequency induction dissolving device, the high-frequency induction dissolving device includes a main machine 11 and an induction coil 12 connected to the main machine 11, and also includes a frame 21 and a feeding tray 22 and a pushing mechanism 30 arranged on the frame 21, the frame 21 is provided with a connecting column 23, the feeding tray 22 is rotatably connected to the connecting column 23, the feeding tray 22 is provided with a through slot, and a lifting bracket 60 for placing the pipe 70 is provided in the through slot;

[0032] The pushing mechanism 30 is disposed below the induction coil 12 . When the pipe 70 follows the lifting bracket 60 and rotates to below the induction coil 12 , the lifting bracket 60 is pushed by the pushing mechanism 30 , thereby pushing the pipe 70 into the induction area of ​​the induction coil 12 .

[0033] The operator can place the pipe 70 on the lifting bracket 60 on the opposite side, rotate the feeding tray 22 to make the lifting bracket 60 located under the induction coil 12, and the pushing mechanism 30 pushes the lifting bracket 60 to send the pipe 70 to the induction area. After the solution treatment is completed, the pushing mechanism 30 is retracted, and the lifting bracket 60 returns to the initial position under the action of gravity, and then the feeding tray 22 is rotated, and the above operation is repeated to perform continuous solution treatment, thereby eliminating the operation of manually sending the pipe 70 to the induction area.

[0034] As a preferred solution, the lifting bracket 60 includes a sleeve rod 61 and a sliding rod 62 connected to each other at the ends, and the sleeve rod 61 is used to place the pipe fitting 70;

[0035] The sliding rod 62 is square, and the through slot is also square. The sliding rod 62 is slidably sleeved in the through slot. A limiting support rod 63 is provided on the side wall of the sliding rod 62. When the sliding rod 62 is inserted into the through slot, the limiting support rod 63 is located above the feeding tray 22.

[0036] The square sliding rod 62 matches the square through slot, limiting the rotation of the lifting bracket 60 in the horizontal plane, which is beneficial to the stability of the pipe 70. The fiber support rod limits the downward travel of the lifting bracket 60, thereby ensuring that the sliding rod 62 is always in the through slot.

[0037] As a preferred solution, the feed tray 22 is provided with a plurality of through slots, and the plurality of through slots are arranged on a circumference with the same radius and the rotation center of the feed tray 22, and the spacing between adjacent through slots is the same;

[0038] A plurality of lifting brackets 60 are arranged on the feeding tray 22, and a plurality of pipe fittings 70 can be placed at the same time. During the specific operation, the workers can also continue to feed the materials while the solid solution is being carried out.

[0039] The feed tray 22 is provided with a toothed disc 25 with the rotation center of the feed tray 22 as the center of the circle, the frame 21 is provided with a stepper motor 50, and the driving shaft of the stepper motor 50 is provided with a gear 51 meshing with the toothed disc 25, and the feed tray 22 is driven by the stepper motor 50.

[0040] A lifting bracket 60 is arranged in a plurality of equally spaced through slots, and the feeding tray 22 is driven by a stepping motor 50, so that the lifting bracket 60 carries the pipes 70 to pass under the induction coil 12 one by one and continuously, and then is pushed into the induction area by the pushing mechanism 30 for heating.

[0041] As a preferred solution, the pushing assembly includes a push rod 32 and a first driving unit 31, and the push rod 32 is drivingly connected to the first driving unit 31; when the push rod 32 moves upward, it pushes the lifting bracket 60 to move upward, and when the push rod 32 moves downward, the lifting bracket 60 is reset under the action of gravity; the first driving unit 31 is a speed-regulating cylinder or an electric push rod. Regardless of whether a speed-regulating cylinder or an electric push rod is used, its function is to drive the push rod 32 to smoothly push the lifting bracket 60.

[0042] As a preferred solution, the pipe 70 solid solution automatic equipment further includes a controller and a proximity switch, wherein the proximity switch is arranged on the frame 21 and is used to detect that the lifting bracket 60 reaches below the induction coil 12;

[0043] The proximity switch, the first driving unit 31 and the stepping motor 50 are all connected to the controller. The detection signal of the proximity switch is transmitted to the controller, and the controller controls the stepping motor 50 and the first driving unit 31 .

[0044] The controller may adopt PLC to control the stepper motor 50 and the pushing mechanism 30. It should be noted here that the PLC is used to control the duration of the pushing mechanism 30 pushing the pipe 70 to the induction zone for heating treatment and the rhythm and stroke of the stepper motor 50, thereby realizing automated solid solution.

[0045] A proximity switch is provided. When the proximity switch detects that the lifting bracket 60 reaches below the induction coil 12, the detection signal is sent to the controller, and the controller controls the first drive unit 31 to start lifting the lifting bracket 60, pushing the pipe 70 into the induction zone and maintaining it for a period of time. The holding time can be preset by the controller, and the preset duration is determined by the pipe 70 currently being solution-heated. Generally speaking, the temperature range of the solution of the pipe 70 is 950°C-1150°C, and the commonly used solution temperature of the pipe 70 processed by the applicant is 1050°C. Combined with the power of the high-frequency induction solution device, the duration of time the pipe 70 remains in the induction zone can be obtained.

[0046] As a preferred solution, the feeding tray 22 is annular, and a connecting rod extending toward the center of the ring is provided on the feeding tray 22, and the connecting rod is rotatably connected to the connecting column 23 through a bearing;

[0047] A work surface is provided on the frame 21, and an opening matching the shape and size of the feed tray 22 is provided on the work surface. A first flange is provided on the edge of the feed tray 22 close to the opening, and a second flange located below the first flange is provided on the inner wall of the opening, and the first flange overlaps the second flange.

[0048] As a preferred solution, a ball or roller for supporting the first flange is provided on the second flange.

[0049] The feed tray 22 rotates around the connecting column 23 to achieve reciprocating feeding; the edge of the feed tray 22 is supported by the cooperation of the first flange and the second flange to ensure the stability of the feed tray 22, and the provision of balls or rollers can avoid frictional contact between the two flanges, thereby avoiding wear and reducing the resistance of the feed tray 22 when it rotates.

[0050] As a preferred solution, the pipe fitting 70 solid solution automatic equipment further includes a material unloading assembly 40, the material unloading assembly 40 includes a second driving unit 41 and a pusher head 42, the material unloading assembly 40 is arranged below the feeding tray 22, the feeding tray 22 is provided with a notch 26 through which the pusher head 42 can pass, and the notch 26 is communicated with the through groove;

[0051] The push head 42 is driven by the second driving unit 41 to move upward, and then the pipe 70 on the lifting bracket 60 is pushed down by the push head 42 .

[0052] The second driving unit 41 is a cylinder or an electric push rod.

[0053] The pushing mechanism 30 and the unloading assembly 40 are arranged one after the other along the rotation direction of the feed tray 22. The pipe 70 is heated at the pushing mechanism 30, and then the pipe 70 is pushed down into the cooling pool by the unloading assembly 40, further improving the automation degree of the equipment.

[0054] As a preferred solution, an arc-shaped spring piece 24 is further provided on the frame 21 . When the lifting bracket 60 is located above the blanking assembly 40 , the arc-shaped spring piece 24 abuts against the pipe fitting 70 on the lifting bracket 60 .

[0055] The arc-shaped spring piece 24 is arranged to press against the pipe 70, so that the lower part of the pipe 70 is tilted toward the side of the push head 42, which is conducive to the push head 42 pushing the pipe 70 upward, and in this way, the upper part of the pipe 70 is tilted against the pipe 70, which is conducive to the pipe 70 falling into the cooling pool. Of course, the second drive unit 41 is also controlled by the controller. Combined with the signal input by the proximity switch, it can be clearly seen that when the proximity switch detects that the lifting bracket 60 is located below the induction coil 12, the last pipe 70 that has completed heating is also moved to the unloading assembly 40 with the lifting bracket 60, and the second drive unit 41 is also started to unload while the pushing mechanism 30 is started.

[0056] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
