Detailed Description
In order to make the technical scheme of the invention easier to understand, the technical scheme of the invention is clearly and completely described by adopting a mode of a specific embodiment in combination with the attached drawings.
The wind shield turning process of the air-cooled explosion-proof motor comprises the following steps:
step one, referring to fig. 3, programming a machining lathe according to the process size of the wind shield shown in fig. 3, and then performing primary gas cutting forming;
turning an inner circle and an outer circle respectively according to a part drawing of the wind shield;
and step three, clamping and positioning the movable part and the tooling die according to the process requirements, and respectively drilling holes according to the drawing.
And in the second step, turning the excircle to a groove with a process requirement size according to the size of the wind shield, wherein the groove is an open groove.
The open slots are evenly distributed in the circumferential direction.
And (3) completely changing the open grooves in the movable part into closed grooves 2 for blanking, reserving the processing amount, and turning the excircle to each closed groove to form the open groove when turning the excircle.
Referring to fig. 1 and fig. 2, the original wind deflector turning process includes the following steps: step 1: programming the relevant sizes of the gas cutting device HDJ according to the inner circle size of phi 1040mm and the outer circle size of phi 1299mm in the graph 1, and then performing gas cutting blanking; and a step 2: according to the wind shield part drawing, respectively turning an inner circle and an outer circle by using a vertical lathe C5116A; step 3: the marking lines are respectively marked into grooves of 10mm multiplied by 22mm on the platform according to the size of the drawing and are evenly distributed; and step 4: aligning according to the processing line of each groove 1, respectively boring into grooves 1 of 10mm multiplied by 22mm by a boring machine T637 as shown in figure 2; step 5: and (3) clamping and positioning the movable part and the tooling die according to the process requirements, and respectively drilling holes of 248 x phi 32.5mm by adopting a drilling machine Z35 according to a drawing.
In the original wind shield turning process, the requirements of drawing size and precision are only considered singly, but the efficiency problems of groove-by-groove alignment and groove-by-groove processing of a workpiece in the process of boring into a groove of 10mm multiplied by 22mm are ignored, the production difficulty and the production efficiency of the process of boring into grooves of 10mm multiplied by 22mm are found to be high and extremely low from the conventional production practice, the production cycle of the workpiece is influenced, the production cycle of the whole motor is influenced, the use efficiency of a boring machine device is further influenced, the production cycles of other related motors are also influenced, and great troubles are brought to the actual production. Therefore, the requirements of all relevant sizes of wind shield parts are comprehensively considered, the most important size in the movable part is guaranteed, the production capacity of the existing equipment is combined, the production process of the original movable part is reasonably improved, the production efficiency of the workpiece is greatly improved while the drawing size is guaranteed, and the production cycle of the motor is prolonged.
Because the '10 mm 22mm slot' in the part mainly plays the role of axial positioning in the motor, the '10 mm 22mm slot' can be uniformly distributed in the circumferential direction and the size of the slot can be ensured, and the slot is in clearance fit with other parts during assembly. The requirement of the factor is comprehensively considered, and the existing equipment capacity is combined, so that the method mainly aims at improving the blanking process method in the new process method. When the original boring technology is changed into a groove of 10mm multiplied by 22mm, the inner circle and the outer circle of blanking gas cutting are carried out, the groove of 10mm multiplied by 22mm is programmed according to the part drawing and is formed by one-time gas cutting. But the excircle size of considering the part again simultaneously and the importance of its relevant spare part cooperation of motor, the requirement of excircle size and precision is extremely high, for size precision and efficiency when guaranteeing the turning excircle, this application is direct to change the open slot in the loose piece into closed slot unloading entirely to keep the processingquantity. When turning the outer circle, turning the outer circle to the closed grooves as the open grooves!
The invention not only ensures that all relevant sizes of workpieces completely meet the requirements of part drawings in the blanking link, but also provides powerful bedding for later-stage inner and outer circle turning and drilling. The marking and processing procedures of the boring groove which are most complicated, longest in construction period and most time-consuming and labor-consuming in the original process are thoroughly cancelled, the production cycle of the movable part and the production cycle of the motor are greatly saved, the production pressure of a boring machine T637 is relieved, and the equipment utilization rate is greatly improved. The original blanking preparation time and the gas cutting inner and outer circle time t are less than or equal to 15 min; the current blanking preparation time, the gas cutting time t for the inner circle, the outer circle and the open slot are less than or equal to 25 min; the preparation time and the slot boring time t of the original scribing and boring open slot process are more than or equal to 520 min. One machine base needs 2 wind shields, and according to the calculation of a motor amount, the improvement of the process method saves time t about 1020min for one motor to work. The process design of the invention not only saves various consumptions of manpower, equipment, cutters and the like, but also brings great economic benefits for saving processing time, reducing the production cost of the motor.
