Detailed Description
The following detailed description of the preferred embodiments of the present invention, taken in conjunction with the accompanying drawings, will make the advantages and features of the invention easier to understand for those skilled in the art and will therefore make the scope of the invention more clearly defined.
Example 1:
as shown in fig. 1, the embodiment provides a method for preparing a conveying track, which includes the following steps:
101. and screening qualified steel as a raw material.
When steel products are screened, at least one detection sample needs to be cut from the steel products to be detected in a clean environment. In this embodiment, the number of the detection samples is ten, the ten detection samples are taken from different positions of the steel material, the shapes and the sizes of the ten detection samples are completely the same, and the cross section of each detection sample is a square of 15 × 25 mm. And then observing the microstructure morphology of each detection sample by using an optical metallographic microscope. The microstructure morphology comprises a microstructure, a decarburized layer, non-metallic inclusions, a macrostructure, an annealed structure and the like, wherein fine grained pearlite is required to be uniformly distributed in the annealed structure of the steel, and the macrostructure of the steel is required to be free of shrinkage cavities, subcutaneous bubbles, white spots and microscopic pores, otherwise, the microstructure is regarded as unqualified. Meanwhile, the internal microstructure of the steel is observed, and the loosening grade of each detection sample is analyzed. And if the porosity grade of each detection sample is smaller than the threshold value, the steel is qualified, and the steel can be used as a raw material. The threshold is typically set to a level of 1.5. Otherwise, the steel product is regarded as defective and cannot be used as a raw material. And storing the qualified raw materials in batches according to the screening structure of the raw materials so as to facilitate subsequent inquiry.
102. And (3) carrying out quenching and tempering treatment on the raw materials so as to change the density and hardness of the raw materials.
The raw materials used for manufacturing the conveying track have to have uniform density and hardness kept at about HRC25 to meet the durability requirement, but the general raw materials are difficult to directly meet the requirement, so that the qualified raw materials screened in the step 101 need to be subjected to quenching and tempering. Specifically, in the process of quenching and tempering the steel, the raw material steel is slowly heated to 900-1000 ℃ by using a quenching and tempering furnace, the temperature is preferably 950 ℃, the temperature is kept for 3-5 hours, and the temperature is preferably 4 hours. Then slowly cooling the raw material to 650 ℃ of 500-. And then, continuously cooling the raw materials until the temperature of the raw materials is reduced to the room temperature, and storing for later use. The hardness of the raw material is reduced in the gradual cooling process, the residual stress is reduced, the size of the raw material tends to be stable, the generation of writing and cracks is favorably reduced, and the density of the material tends to be uniformly distributed.
In order to ensure that the quenched and tempered steel still has a flat surface and the flatness of the surface meets the processing requirements, mechanical correction of the quenched and tempered raw material is generally required. In the mechanical calibration process, the surface of the raw material is mainly pressurized and calibrated by using a hydraulic press, the hydraulic press is a special hydraulic press with the pressure maintaining time of more than 25t, and the pressure maintaining time of the hydraulic press is more than or equal to 0.5h, and is preferably 0.5 h. The mechanical correction is mainly to ensure that the subsequently manufactured conveying track has flat upper and lower surfaces. It is noted that prior to mechanical calibration, the dedicated hydraulic press planes need to be cleaned in depth to ensure that the calibration process is free of impurities damaging and affecting the surface of the raw material.
103. And (3) processing the raw material by using a numerical control lathe, and turning a reference surface, wherein the flatness of the reference surface is less than 0.01 mm.
The processing of the reference surface needs to be carried out in a precision processing workshop, redundant parts on the surface of the raw material are removed by the numerical control machine, namely uneven parts on the surface of the raw material are removed, so that a reference ground required by subsequent processing is reserved, then the numerical control machine is used for carrying out finish turning on the reference ground, the flatness of the reference ground is smaller than 0.01mm, and the reference surface is obtained.
Once the reference surface is turned, the mounting hole can be machined at the preset position of the raw material by taking the reference surface as the reference surface, namely, the mounting hole machining step is carried out. It should be noted that, in the process of machining the mounting hole, it is necessary to remove the burrs, iron chips and oil stains on the surface of the raw material by the worker using water flow. Then, the worker carries out heating hardening treatment on the raw material by using high-frequency induction heating equipment to form a hardened layer on the surface of the raw material, the hardness of the hardened layer is HRC52-55, and the hardened layer has good surface wear resistance. Meanwhile, in order to avoid the micro deformation of the raw material during the heat curing treatment, the surface of the raw material subjected to the heat curing treatment needs to be pressurized and corrected by the oil press again after the heat curing treatment, a special oil press with a pressure maintaining time of more than 25t is adopted as the oil press, and the pressure maintaining time of the oil press is more than or equal to 0.5h, preferably 0.5 h. Deep cleaning of the plane of the oil press is still required before the press calibration. And finally, fixing the raw material with a good surface on a processing table of a numerical control machine tool, in order to keep the stability and accuracy of the processing process of the mounting hole, generally clamping a reference surface of the raw material on the processing table of the numerical control machine tool, directly processing the mounting hole at a preset position of the raw material by using the numerical control machine tool, wherein the processing process of the mounting hole is carried out according to the sequence of processing a bottom hole and then processing a counter bore, and the angle of the hole position of the mounting hole is ensured to be between-0.1 degrees and +0.1 degrees in the processing process, and is preferably 0 degree. It is noted that before the datum plane is clamped on the machining table, the clamping fixture must be modified to ensure a smooth, twist-free clamping. And finally, chamfering the hole positions of the mounting holes by 0.2mm to obtain the mounting hole structure meeting the requirements.
104. Turning the height and the width of the raw material by using a numerical control lathe to obtain a blank, wherein the height and the width of the blank are respectively reserved with machining allowance of 0.05-0.08 mm.
The size of the blank directly affects the precision of the conveying track, so that when the blank is prepared by turning the raw material, the raw material needs to be turned for many times and gradually processed to the required size. The height and width of the turned blank need to be respectively reserved with machining allowance of 0.05-0.08mm, so that an operating room is provided for subsequent machining, and the machining quality is convenient to improve.
Generally, in order to ensure that the size of the blank meets the requirements of subsequent processing, after the blank is formed, the blank needs to be subjected to shape detection. In the shape detection process, a digital display height gauge and a micrometer are combined to detect different parts of the blank, and then whether the blank is qualified or not is evaluated according to detection results of the different parts. Specifically, the digital display height gauge is clamped on a lathe tool rest, the size of each side face of the blank is detected through the movement of the lathe tool rest and the rotation of a lathe chuck, and in the detection process, a turning tool can locally correct the blank according to the measured value of the digital display height gauge. Then selecting at least eight detection points on the corrected blank, measuring the size of each detection point by using a micrometer, and if the size of each detection point is within a tolerance range of 0.05-0.08mm, determining that the appearance is qualified; otherwise, the height and the width of the blank are continuously turned by using the numerical control lathe until the requirements are met.
105. And carrying out rough turning on the blank by using a numerical control lathe to obtain a rail surface structure, wherein a machining allowance of 0.05-0.08mm is reserved in the rail surface structure.
The machining precision requirement of the track surface structure is high, and the blank is generally turned for multiple times by using a numerical control lathe and is gradually machined to the required size so as to improve the turning precision. In order to ensure that the dimensional accuracy of the track surface structure meets the requirements and avoid wasting subsequent process cost, the track surface structure obtained usually needs to be subjected to further detection and calibration before entering the next process. In the detection and calibration process, the micrometer needs to be clamped on a tool rest of the numerical control lathe, a chuck of the numerical control lathe is rotated, and the appearance precision of each part of the track surface structure is detected, so that the size precision of the track surface structure is ensured to be within the range of 0.05-0.08 mm. And then, a hand-held hardness tester is used for detecting the hardness of the surface of the track surface structure, and different parts are selected from hardness test points so as to ensure that the hardness of the track surface structure is HRC 52-55. And then clamping the dial indicator on a tool rest of the numerically controlled lathe, and manually carrying out fine adjustment on the track surface structure according to the measurement result of the dial indicator to ensure that the planeness of the track surface structure is less than 0.05 mm. And finally, deburring and chamfering the track surface structure by using a chamfering machine. When all the detection and calibration are completed, the track surface structure basically meets the processing requirements, and the next procedure can be carried out.
106. And (4) carrying out fine grinding and shaping on other surfaces except the track surface structure on the blank to keep the appearance of the blank smooth. The dimensional accuracy of the blank after the fine grinding and shaping of other surfaces except the track surface structure is ensured to be within 0.02 mm.
In order to improve the polishing precision of the surfaces of the blank except the rail surface structure and improve the product quality, the dimension of the blank after the fine grinding and shaping is generally detected. Specifically, the dial indicator is clamped on a grinding head of a grinding machine, and other surfaces except the track surface structure on the blank are detected to ensure that the flatness of other surfaces except the track surface structure on the blank is less than 0.02 mm.
107. And grinding the track surface structure by using a grinding machine to ensure that the dimensional accuracy of the track surface structure is less than 0.02 mm.
In order to further improve the grinding accuracy when the raceway surface structure is reprocessed, it is necessary to control the feed amount per grinding machine to be less than 0.005mm, preferably 0.002 mm. The track surface structure is gradually ground to a preset size by a method of grinding for multiple times and a small amount of grinding each time. And after the grinding treatment of the track surface structure is finished, clamping the dial indicator on a grinding head of a grinding machine, and detecting the precision of the track surface structure by using the dial indicator to ensure that the dimensional precision of the track surface structure is less than 0.02 mm.
108. And carrying out rust prevention treatment on the track surface structure by using rust preventive oil.
In order to improve the rust prevention function of the product in the using process, the track surface structure is generally subjected to rust prevention treatment by using special rust prevention oil. Of course, rust prevention may cause errors in the track surface structure, and therefore, deviation detection is also performed on the rust-prevented track surface structure, and if the deviation is larger than 0.02mm, polishing correction needs to be continued until the deviation is smaller than 0.02 mm. In this embodiment, the deviation detection is mainly realized by combining a micrometer and a handheld hardness meter, and the detection method is similar to the foregoing method and is not described herein again.
109. Grinding the rust-proof rail surface structure by using a grinding machine to ensure that the dimensional accuracy of the rail surface structure after grinding is less than 0.01mm to obtain a finished product, as shown in figure 2.
In order to ensure that the finished product is a qualified product meeting the requirements, the finished product needs to be subjected to full inspection, namely comprehensive inspection. And in the full inspection, the finished product is detected by sequentially utilizing the micrometer, the hardometer, the dial indicator and the go-no go gauge, and when the detection of the micrometer, the hardometer, the dial indicator and the go-no go gauge is up to standard, all parameters of the finished product are considered to meet the requirements, so that the finished product is a qualified product.
