Abstract
The utility model relates to a synchronous grinding machine for pencil cores. A carborundum grinding wheel which is provided with a tilting edge and has high intensity and a plane guide wheel are correspondingly arranged, and the distance between the outer circles of the carborundum grinding wheel and the plane guide wheel is equal to the radius of the pencil core; accordingly, a plurality of sections of the incoming rod pencil core can be subjected to the high-speed grinding. The cutting operation is simultaneously completed during the grinding and shaping.
Description
The utility model relates to the synchronous grinder of a kind of lead in a pencil.
The lead in a pencil grinder of prior art generally can not contain into the grinding and the intercept of pencil lead synchronously simultaneously, so production efficiency is low, is not suitable for modern production and uses.
The purpose of this utility model just provides the synchronous grinder of a kind of lead in a pencil.
The synchronous grinder of lead in a pencil that provides according to the utility model, mainly formed by an emery wheel and a guide wheel and a pneumatics nozzle, wherein this emery wheel and guide wheel two cylindrical tangent line relative distances are the radius of pencil lead pole stock, the two last angles of taking turns are provided with the pneumatics nozzle of a roof pressure pole stock again, in addition this emery wheel most grinding tool of serving as reasons is listed as according to the length relation of moulding pencil lead and establishes, and the tapering of the corresponding shaping pencil lead in cutting face and be provided with corresponding gradient.
The synchronous grinder of lead in a pencil that provides according to the utility model, wherein emery wheel and guide wheel up angle one side can lead to a charging gear with timing function through a slideway.
According to the synchronous grinder of lead in a pencil that the utility model provides, in it and emery wheel periphery and slideway outlet, jet expansion, blowdown road intake section form a housing and cover, and can establish a filter towards a dust exhaust apparatus at blowdown road descending.
The synchronous grinder of lead in a pencil of the present utility model compared with prior art; can finish the grinding and the intercept effect of pencil lead synchronously simultaneously; can be significantly many times enhance productivity; the pencil lead that this grinder ground; be cover joint formula pencil (as shown in Figure 1); this pencil lead is a little section lead in a pencil towards the oblique shape of paracone; and the predecessor of its formation is shaft-like; this shaft-like pencil lead generally can directly be made as box-like the sharpening a pencil of wood; first through being processed into cover joint formula pencil lead; and pencil lead grinding operation in the early time; only can develop two little section pencil leads with single board per minute; trace it to its cause is that the physical property of processing mode and cutter is poor; general processing mode have grind again behind the first intercept two ends be point tiltedly after the shape again severing be two; or have and grind out the tiltedly portion's severing again of end point in regular turn; on procedure, can't finish many simultaneously; in addition grinding rate slowly principal element for generally all with the silicon emery wheel as milling cutter; softer on the quality; precision is wayward; it is easily deformable to grind the edge of a knife at a high speed; and often need shutdown to flatten the edge of a knife; so the utility model spy is grinding synchronously with the processing mode improvement; moulding simultaneously; and adopt high-intensity corundum emery wheel; wear-resisting and the high accuracy profile by it and can reaching at a high speed is in order to avoid shut down leveling.

The synchronous grinder of lead in a pencil of the present utility model mainly is by a corundum emery wheel 1(as shown in Figure 2) stand facing each other with a plane guide wheel 2 levels, the top is provided with a timing charging gear 3, two take turns angle just is being provided with a pneumatics nozzle 4 and a beneath dust exhaust apparatus 5, at first with 31 li of pencil lead pole stock M horizontal material bins, hopper 31 positive incisions are provided with a feed with hopper 321 and take turns 32, feed is taken turns 32 cylindricals by a baffle plate 311 encirclements again, then pole stock M1 freely falls into hopper 321 and turned right by feeding to return back to below slideway 33 to fall, fall to placing on the angle of emery wheel 1 and guide wheel 2 by slideway 33 guidings, and cut distance because of the circle relatively of two wheel bodys and be the radius of pole stock, therefore may be stuck in angle position on it, and ground by emery wheel 1, in the time of abrasive action, angle to last set pneumatics nozzle 4 provide a suitable air pressure with pole stock M1 compress into, and formation feed phenomenon, and keep unlikely the floating of pole stock M1 and maintenance feed action, emery wheel 1 and guide wheel 2 export slideways 33 with nozzle 4 again, between outlet and a blowdown road 6 inlets, form chlamydate housing H, to prevent that abrasive dust from flying out, and near blowdown road 6 inlet descending, be provided with a filter 51 and a dust exhaust apparatus 5 formation one dust sucting pipeline, can be with the break flour control of dust.
The situation (as shown in Figures 3 and 4) of other its synchronous processing, Fig. 3 is abrasive wheel configuration vertical view, this abrasive wheel 1 is by majority, row are located at axle center 12 according to moulding pencil lead M2 Len req relation with circular grinding tool 11 that corundum forms, and the edge of a knife of each grinding tool 11 has and the corresponding gradient θ of moulding pencil lead M2 tapering, Fig. 3 is ground the state when cutting for pole stock M1 falls into, be the angle of whole Zhi Yuan across abrasive wheel 1 and guide wheel 2, being subjected to synchronously of beginning, multi-section grinds simultaneously, and form desired moulding pencil lead M2(gradually as shown in Figure 4), in its forming process, utilize grinding tool 11 feed faces for having and the corresponding gradient θ of pencil lead M2 tapering, make pencil lead form taper, utilize plane 110, grinding tool left side again, the edge of a knife that forms with gradient θ 111 is radially cut it, the center point P (shown in Fig. 4-1) that arrives pole stock is treated as the cut-out action, make shaping pencil lead M2 form monolithic entity, pencil lead M2 after the moulding takes off because of fallen down by pneumatics nozzle (as shown in Figure 2) roof pressure effect, and through blowdown road 6 and colony in magazine 61.
