Abstract
The invention relates to a novel machining method for a medium plate step with a chamfering surface of a scraper conveyor. The novel machining method is characterized by comprising the following steps: firstly rotating a medium plate to be machined to a chamfering surface of a step by utilizing an adjustable tool and enabling the medium plate to be at a horizontal position, then milling a chamfering surface at a distal end by taking the axis of a disc milling cutter of a milling machine as a vertical direction, and then rotating a vertical shaft of the disc milling cutter to a vertical position for milling into a stepped surface. According to the technical scheme of the invention, the novel machining method has the following beneficial effects that the energy saving effect is significant, and by adopting the technology provided by the invention, four times of feeding during machining are directly converted into two times of feeding, so that the total efficiency is increased by 60%; and the stress of a cutter bar is converted from main transverse stress to main axial stress, so that the machining stability of a machine tool is improved.
Description
Technical field
The present invention relates to the novel processing method of pallet rank band fillet surface in a kind of drag conveyor.
Background technology
Middle plate is as the intermediate channel major part of drag conveyor, and consumption is very large.Because China's geological conditions change is various, have demand in enormous quantities for intermediate channel, middle plate wearability and working (machining) efficiency have much room for improvement.
As shown in Figure 2, traditional processing mode is as follows: 1, first milling machine cutterhead or slotting cutter axis are placed in upright position and divide three vertical feeds, be whittled into the straight platform of the wide 33-42mm of dark 20mm at middle plate facing cut.2, by slotting cutter or end milling cutter head axis with vertical direction transverse rotation 18 ° 26 ', then milling becomes 5 × 15 chamferings at step place.Find through Long-Time Service, it has the following disadvantages: 1, raw material hardness and wearability improve, and utilize the side cut sword of milling cutter to be main cutting edge, knife bar is subject to powerful lateral cutting forces, cutterhead bad stability, vibrates larger.2, cutting data is unbalanced, and during milling step, cutting output is large, and need two, three feedings just can complete step dimension processing, during milling chamfering, Tool in Cutting amount is by less than normal.3, stock-removing efficiency is low.
Summary of the invention
The object of this invention is to provide the novel processing method of pallet rank band fillet surface in a kind of dependable performance, energy-conservation, efficient drag conveyor.
The novel processing method of pallet rank band fillet surface in a kind of drag conveyor, its special feature is, comprise the steps: first to utilize adjustable tool middle plate rotation to be processed to be horizontal to step fillet surface, again by the wire rod quality axis of milling machine with vertical direction, tip mills out fillet surface, and then wire rod quality vertical shaft is gone to upright position, be milled into step surface.
Technical scheme of the present invention has following beneficial effect: 1, energy-saving effect is remarkable, adopts technology of the present invention, makes to add four feedings in man-hour, be directly converted to twice feeding, always puies forward efficiency and improves 60%; 2, knife bar stressed by lateral stressed be main, it is main for becoming axially loaded, improves the stability of machine tooling.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of middle plate;
Accompanying drawing 2 is the schematic diagram of processing mode in background technology;
Accompanying drawing 3 is the schematic diagram of the inventive method.
Detailed description of the invention
As shown in Figure 1,3, the invention provides the novel processing method of pallet rank band fillet surface in a kind of drag conveyor, comprise the steps: first to utilize adjustable tool middle plate rotation to be processed to be horizontal to step fillet surface, again by the wire rod quality axis of milling machine with vertical direction, tip mills out fillet surface, and then wire rod quality vertical shaft is gone to upright position, be milled into step surface.
The special feature of the inventive method is: as shown in Figure 3, by the wire rod quality axis of milling machine with vertical direction, utilize adjustable tool to rotate step fillet surface to be horizontal, tip mills out fillet surface, the cutting data of balanced feeding each time, it is main for being cut by radial cutting sword by cutterhead, is converted to end face sword for main cutting edge, changes the Impact direction of handle of a knife.Adopt the processing method of pallet rank band chamfering end face in the present invention, tip Milling Machining fillet surface, then machine table terrace, change the stressing conditions of cutter in machine tooling, improve processing conditions, improves working (machining) efficiency.Adopt present invention process, by an oblique surface machining, a table top processing, twice feeding completes manufacturing procedure.
