As shown in fig. 2, the processing method mainly includes the following steps:
101, detecting a rake material to be processed by adopting a flaw detection method, wherein the rake material to be processed is GH3039;
102, processing the shape of the measuring rake by the material to be processed according to the drawing requirements;
103, finishing the processing of a first area in the measurement rake cavity through a wire cutting process, and finishing the processing of a rake seat pipe discharge hole on the measurement rake through a gang drilling and milling process; two side walls of the first area, which are adjacent to the rake seat pipe discharge hole, and the first area form through holes for arranging pressure measuring pipes; the rake seat pipe discharge hole is communicated with the first area;
and 105, arranging a pressure measuring pipe in the first area according to the shape of the first area from inside to outside through a pipe penetrating tool, and straightening the pressure measuring pipe extending out of the rake seat exhaust pipe hole through the pipeline straightening tool outside the rake seat exhaust pipe hole.
Before step 101, the material for processing the measuring rake needs to be detected by a flaw detection method, which aims to detect whether there is a defect or structural abnormality in the interior or surface of the raw material through flaw detection, and control the flaw detection method accordingly, so as to prevent the raw material which does not meet the quality requirement from flowing into the processing production, and avoid waste of manpower, material resources and financial resources. In practical applications, the flaw detection method may include any one of X-ray flaw detection, ultrasonic flaw detection, magnetic particle flaw detection, penetrant flaw detection (dye flaw detection), eddy current flaw detection, gamma ray flaw detection, and fluorescence flaw detection.
In the present example, the rake preparation material GH3039, t 74X 120X 425 slabs were measured.
In step 101, after the material for processing the measurement rake is selected by the flaw detection method, the material can be prepared according to the drawing requirements. In practical applications, the actual dimensions of the materials required by different measuring rakes are different, so that the specific dimensions of the materials need to be determined according to specific drawing requirements when the measuring rakes are processed.
In step 102, the shape of the measuring rake is processed according to the drawing requirements by the material of the measuring rake to be processed. Fig. 3 is a schematic view of a measuring rake structure according to an embodiment of the present invention, wherein the outer side of the measuring rake after being processed is similar to the measuring rake structure shown in fig. 3, but the cavity of the measuring rake is not processed yet.
In step 103, as can be seen from the measurement rake structure diagram provided in fig. 3, the measurement rake body 101 includes a rake body and a pressure measuring tube 102 disposed in the cavity. Since the outer side of the measurement rake has been machined in step 102, the measurement rake cavity machining is required in step 103. As shown in fig. 4 and 5, the measurement rake cavity mainly includes a first region 103 and a rake socket pipe outlet 104, that is, when the measurement rake cavity is processed, the first region 103 and the rake socket pipe outlet 104 need to be processed sequentially.
Specifically, the machining of the first region 103 in the measurement rake cavity is completed by a wire cutting process, and after the machining of the first region 103 is completed, the machining of the rake seat exhaust hole 104 needs to be completed later. In the embodiment of the present invention, the processing of the first region 103 is wire-cut processing, the shape of the first region 103 formed after wire-cut is an irregular through hole, and the first region 103 is used for disposing the pressure measuring pipe 102; further, a rake drain hole 104, which is in communication with the first region 103, is also used to provide the pressure measuring tube 102. Specifically, the rake seat pipe discharge hole 104 is formed in the measuring rake, and is shaped like a waist-shaped long hole, and the waist-shaped long hole can ensure that the pressure measuring pipe 102 extending from the first region 103 can completely pass through the waist-shaped long hole. Because the measuring rake is made of GH3039, the strength of the measuring rake is high, and the rake seat row pipe hole 104 is a slender hole, the rake seat row pipe hole 104 is made in a mode of combining gang drilling and milling processing in the embodiment of the invention.
It should be noted that two side walls of the first region 103 adjacent to the rabble arm exhaust hole 104 and the first region 103 form a through hole. According to fig. 3 and as shown in fig. 4, the through-hole can divide the cavity of the measurement rake into an upper structure and a lower structure.
In the embodiment of the invention, the depth of the waist-shaped long hole is 40mm, and the width of the waist-shaped long hole is 4mm.
After the first region 103 included in the measurement rake cavity and the rake seat exhaust hole 104 included in the measurement rake are machined, a plurality of pressure measuring pipe 102 arrangement holes and sensor arrangement holes need to be machined in the measurement rake body. In practical applications, the holes for installing the pressure measuring tube 102 have the same diameter, and the holes for installing the sensors are concentric stepped holes, as shown in fig. 4, the concentric stepped holes include a first through hole and a second through hole, the second through hole is close to the first region 103, and the diameter of the second through hole is larger than that of the first through hole.
In step 104, since the holes for installing the pressure measuring tubes 102 are formed, and the diameters of the holes are uniform, the holes for installing the pressure measuring tubes 102 may be sequentially formed from top to bottom on the measuring rake body by a machine tool machining method. The first region 103 is located in the measurement rake cavity from top to bottom, i.e. from above the measurement rake body.
Since the concentric stepped hole of the sensor is provided, the diameter of the second through hole close to the first region 103 is larger than that of the first through hole, and therefore, if the conventional machining method is used, the second through hole cannot be machined. In order to solve the above problems, an embodiment of the present invention provides a tool for machining a concentric stepped hole, as shown in fig. 6, which is a wiring pipe hole stepped drill, and a hand-held portion of the wiring pipe hole stepped drill is identical to an existing electric drill, but includes a drill portion 105 different from an existing drill. Specifically, as shown in fig. 7, the drill part 105 of the wiring pipe hole stepped drill comprises a homemade drill 201-1, a fixing sleeve 201-2 and an extension rod 201-3 in sequence from far to near. In practical application, the homemade drill bit 201-1 and the extension bar 201-3 are made of hard alloy steel, and the extension bar 201-3 made of hard alloy steel can be bent.
Further, since the diameter of the second through hole included in the concentric stepped hole is larger than that of the first through hole, when the second through hole is processed, the second through hole needs to be processed from bottom to top on the measuring rake body. According to the wiring pipe hole step drill provided by the embodiment of the invention, the extension rod 201-3 can be bent, so that the wiring pipe hole step drill can be arranged in the first area 103, and the self-made drill 201-1 is used for processing a second through hole from bottom to top along the measuring rake body.
It should be noted that the first through hole included in the concentric stepped hole may be machined by using an existing machine tool, or the machining of the first through hole may be completed from top to bottom on the measuring rake body by using the stepped drill bit for routing the pipe hole provided in the embodiment of the present invention. The processing manner of the first through hole is not particularly limited.
It should be noted that, the concentric stepped hole for installing the sensor may include a first through hole having a hole diameter of
The second via hole may have an aperture of
After the installation holes of the pressure measuring pipe 102 and the installation holes of the sensors on the measuring rake body are processed, the pressure measuring pipe 102 can be arranged in the measuring rake body.
In step 105, in practical applications, the arrangement mode of the pressure measuring tube 102 needs to be determined according to the structure of the first region 103 in the measurement rake cavity and the space of the arrangement hole of the pressure measuring tube 102. In the embodiment of the invention, in order to bend and fix the pressure measuring pipe 102 arranged in the first cavity, a pipe penetrating tool is selected to complete the arrangement of the pressure measuring pipe 102.
As shown in fig. 8, the pipe penetrating tool provided by the embodiment of the present invention includes a handle, a wire cutter 302 connected to the handle through a movable shaft, and a self-made chuck 301 disposed at a front end of the wire cutter 302. In the embodiment of the present invention, since the pressure measuring tubes 102 have different specific apertures, in order to match the pressure measuring tubes 102 having different apertures, the self-made collet 301 provided in this embodiment includes three clamping holes having different apertures, as shown in fig. 9, the self-made collet 301 includes three clamping holes having apertures respectively corresponding to the apertures
And
in practical application, according to the diameter of the pressure measuring pipe 102, a clamping hole matched with the diameter of the pressure measuring pipe 102 is selected from a self-made clamping head 301 included in the pipe penetrating tool, and the clamping hole successfully matched at present is called a first clamping hole. Further, the pressure measuring pipe 102 is arranged in a first clamping hole, the pressure measuring pipe 102 is fixed through the first clamping hole, and the fixed pressure measuring pipe 102 is arranged in a first area 103 through a pipe penetrating tool.
It should be noted that, the homemade chuck provided by the embodiment of the present invention is made of copper metal and is arranged at the front end of the wire pliers by welding.
Further, the pressure measuring tube 102 penetrating into the first cavity may extend out of the rake seat drain hole 104 along the first cavity, and in order to arrange the pressure measuring tube 102 extending out of the rake seat drain hole 104, in this embodiment of the present invention, preferably, the pressure measuring tube 102 extending out of the rake seat drain hole 104 is aligned by a tube alignment fixture 401 disposed outside the rake seat drain hole 104. Specifically, as shown in fig. 10 and 11, the pipe straightening tool 401 includes a central bore 402, and the pressure measuring pipe 102 extending out of the rake header exhaust hole 104 penetrates through one end of the central bore 402, penetrates through the central bore 402, and extends out of the other end, so that the pipe straightening tool 401 can straighten the pipe.
