Described upper radiation fins 3 and lower radiation fins 5 are rectangular rubber radiation fins.
The length of described upper radiation fins 3 is less than the length of lower radiation fins 5.
Operation principle: first carry out material loading, in the time of work, in the time driving the piston rod of cylinder 521 to stretch out, that two connecting rods 526 one end of being hinged on slippage parts 525 is close to both sides, thereby two clamp portions 523 are moved laterally, tool clamp mechanism 52 is realized to be opened, and in the time driving the piston rod of cylinder 521 to retract, one end that two connecting rods 526 are hinged on slippage parts 525 is drawn close mutually, thereby realize left clamp 5231 and right clamp 5232 and clamp cutter to be processed, need the cutter of grinding to be clamped in notch 5233 with regard to making like this, work in because two bent plate portions 531 are 90 ° of angles, therefore be arranged on two tool clamp mechanisms 52 in bent plate portion 531 in the time that one of them tool clamp mechanism 52 is positioned at horizontal level another tool clamp mechanism 52 be positioned at vertical direction, the tool-holder consolidation of not grinding is showed feeding from loading plate by the left clamp 5231 and the right clamp 5232 that are positioned at the tool clamp mechanism 52 of vertical direction, cutter is taken off from working head and the tool-holder consolidation that the tool clamp mechanism 52 that is positioned at horizontal level completes grinding is existing, then the position that the rotary part of rotary cylinder 51 action realizes two tool clamp mechanisms 52 is exchanged, now unclamp left clamp 5231 and right clamp 5232, now being positioned at the cutter that the tool clamp mechanism 52 on vertical direction completes grinding is placed on loading plate, the effect that the tool clamp mechanism 52 that is positioned at horizontal level shrinks by the push rod of mobile cylinder 11, make slipping block 512 move to the clamping device place of main shaft along slide block 513, make the cutter that is positioned at horizontal level by main shaft clamping device clamping, and then retract, the mode of discharging is also identical, its make charging and discharging quick, convenient, greatly promote operating efficiency.
Wherein, because being fixed with cylindrical block 5132 by the both sides of horizontal block 5131, slide block 513 forms, and slide block 513 sleeves are in the transverse concave groove 5121 of slipping block 512, cylindrical block 5132 is pressed against on the bottom surface of transverse concave groove 5121, be equivalent to like this slipping block 512 and slide block 513 just two directly contact, its contact area is little, frictional force is little, improve the speed of slippage, simultaneously, reduce friction, and cylindrical block 5132 is bolted on connecting portion 5133, like this when after cylindrical block 5132 serious wear need to be replaceable by backing out bolt, very convenient.
Simultaneously, on slipping block 512, form multiple screws 530, be bolted to connection on slipping block 513 and be connected and fixed plate 514, can be bolted in different screw 530 and realize the diverse location of cutter rotating and clamping device 520 on slipping block 512 being connected and fixed plate 514 like this, the cutter to be processed that meets different length be realized clamping material loading and blanking.
Complete after material loading; rotate by drive motors 7; drive main transmission screw mandrel 6 to rotate that (wherein all there is screw thread at the middle part of main transmission screw mandrel 6; two ends are without screw thread); thereby emery wheel main shaft contiguous block 4 is moved up and down along main transmission screw mandrel 6; make to be fixed with the cutter head being fixed with on the grinding spindle of spindle drive motor in spindle drive motor housing 43 cutter is carried out to grinding; when mobile; upper radiation fins 3 and lower radiation fins 5 have protection main transmission screw mandrel 6 and are not stained with iron and cut the effect that waits the fragment that processing produces, thus the normal operation of guarantee equipment.Its emery wheel main shaft contiguous block 4 by the top and bottom of main connect box 41 and main connect box 41 be bolted to connection by the piece 42 that is spirally connected form, like this, in the time that damaging, the piece 42 that is spirally connected only need to change the piece 42 that is spirally connected by backing out bolt, and without changing whole emery wheel main shaft contiguous block 4, it is easy to maintenance.
And in the upper plane of its lower supporting plate 1, be fixed with projection circle 11; in projection circle 11, be inserted with stop sleeve 12; stop sleeve 12 is fixed on the upper surface of lower supporting plate 1; in stop sleeve 12, be fixed with spring bearing 13; the lower end of main transmission screw mandrel 6 is fixed in spring bearing 13; this stop sleeve 12 not only has the effect of supporting main transmission screw mandrel 6; and there is the position that is connected with the output shaft of drive motors 7 by shaft coupling, protection main transmission screw mandrel 6 bottoms and be not subject to the impacts such as extraneous collision, raising service life.
And the upper portion side wall of described upper connecting through hole 21 forms annular groove 23, elastic packing piece 8 sleeves are in upper connecting through hole 21, the lateral wall of elastic packing piece 8 is embedded in annular groove 23, elastic packing piece 8 is in the upper end of main transmission screw mandrel 6, by the sealing effectiveness of elastic packing piece 8, thereby extraneous dust, the iron that can prevent upper backup pad 2 are cut etc. to enter and in connecting through hole 21, are affected the normal operation between main transmission screw mandrel 6 and the upper spring bearing 22 in it.
Described elastic packing piece 8 structures are, the annular sidewall of circular block 81 is taper, the upper surface of circular block 81 forms annular low groove 82 near side-walls, between annular low groove 82 and the sidewall of circular block 81, form at least two jacks 83, the middle part of circular block 81 forms lug boss 84, the end face of lug boss 84 forms connecting screw hole 85, so when mounted, can be screwed onto in connecting screw hole 85 circular block 81 is filled in upper connecting through hole 21 by screw rod, due to the effect of annular low groove 82, on filling in connecting through hole 21 time, the outer wall of elastic packing piece 8 is to internal strain, guarantee elastic packing piece 8 can normally be filled in, then when mobile annular groove 23 place, elastic packing piece 8 outer walls are replied, thereby elastic packing piece 8 is embedded in annular groove 23, then screw rod is unloaded, and in the time that needs unload elastic packing piece 8, as long as screw rod is screwed onto in connecting screw hole 85, pitman sleeve holding are in jack 83, then will between pitman, connect by connecting line, connecting line middle part is twisted or is pulled outwardly, thereby make pitman close to centre, so just make the outer wall of elastic packing piece 8 close to centre, from annular groove 23, be shifted out, finally pull screw rod, it is extracted out and unloaded from upper connecting through hole 21, it is compared with the mode of existing employing end cap seal, it is not only lightweight, and make simple, it is convenient to change.
