Abstract
The utility model discloses a kind of rotary wire drawing machine sand box fixed structure, comprise seat board and sand box, bottom, described sand box both sides is all connected with the limiting plate of rectangle, limiting plate has a cam through hole, described seat board has the manhole aligned with cam through hole great Duan center, also comprise the rotating shaft that top is connected with cam, this cam and cam shape of through holes size match and are placed in limiting plate top, and rotating shaft lower end is successively through cam through hole and manhole.The utility model has that structure is simple, low cost of manufacture, that abrasive sand is changed is convenient, without the need at substantial manpower and time, wire rod glacing flatness advantages of higher.
Description
Technical field
The utility model relates to wire drawing machine design and manufaction technical field, is specifically related to a kind of rotary wire drawing machine sand box fixed structure.
Background technology
Metal drawing belongs to the metallic articles such as standard component and produces pre-processing system, object be in order to by the production and transport of steel manufacturer to the wire rod of the metallic article manufacturing enterprises such as standard component or bar through the drawing process of wire drawing machine, make the diameter of wire rod or bar, circularity, inner structure, surface smoothness and aligning degree all reach the Feedstock treating requirement of the metallic article need of productions such as standard component.Wire rod needs to carry out two steps before entering wire drawing machine, and the first removes wire surface oxide-film or scale crust; It two is that wire rod is stretching in advance, and deoxidation film is completed by the sand box that abrasive sand is housed, and to stretch in advance be come by a cylinder.
For the surface treatment of wire rod, existing wire drawing machine has generally been come by one or more sand box that abrasive sand is housed, sand box two ends have wire guide, but in order to ensure can not to offset in drawing process, sand box is generally all welded in metal frame, and the abrasive sand in sand box is need to change in use for some time, but because sand box is welded on cannot dismantle in metal frame, bit by bit in the sand box of all round closure, abrasive sand slowly can only be taken out when changing abrasive sand, obviously in this there is abrasive sand and change not thorough in structure, length consuming time, the problems such as hand labor intensity is large, although namely existing sand box can ensure the glacing flatness of wire rod in drawing process, but the problem that difficulty is changed in abrasive sand cannot be solved.
Utility model content
The utility model aims to provide a kind of rotary wire drawing machine sand box fixed structure, changes the problems such as not thorough, consuming time length, hand labor intensity are large to solve abrasive sand existing for existing wire drawing machine sand box.
The utility model is achieved by following technical solution:
A kind of rotary wire drawing machine sand box fixed structure, comprise seat board and sand box, bottom, described sand box both sides is all connected with the limiting plate of rectangle, limiting plate has a cam through hole, described seat board has the manhole aligned with cam through hole great Duan center, also comprise the rotating shaft that top is connected with cam, this cam and cam shape of through holes size match and are placed in limiting plate top, and rotating shaft lower end is successively through cam through hole and manhole.
Be matched in clearance between described cam and cam through hole, gap size is 0.5-1mm.
Described rotating shaft bottom is connected with rotating handles.
Described sand box rear and front end is all connected with handle.
The beneficial effects of the utility model are:
Compared with prior art, the rotary wire drawing machine sand box fixed structure that the utility model provides, realizes the locking to sand box by limiting plate and the cam of its both sides, makes sand box stably be arranged on seat board, effectively can ensure the glacing flatness of wire rod; And realize the locking to the sand box in chute by rotating shaft, cam and cam through hole, avoid the problem occurring that sand box slides or comes off; In addition, cam can be overlapped with cam through hole by rotating shaft, namely by shaking hands sand box quick-detachment, the replacement operation of abrasive sand becomes simple and convenient; Compared to traditional wire drawing machine sand box, the utility model has that structure is simple, low cost of manufacture, that abrasive sand is changed is convenient, without the need at substantial manpower and time, wire rod glacing flatness advantages of higher.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model;
Fig. 2 is top view of the present utility model;
In figure: 1-seat board, 2-sand box, 3-limiting plate, 4-rotating shaft, 5-rotating handles, 6-cam, 7-cam through hole, 8-shakes hands, 9-manhole.
Detailed description of the invention
Below in conjunction with accompanying drawing, the technical solution of the utility model is described further, but described in required protection domain is not limited to;
As shown in Figure 1-2, the rotary wire drawing machine sand box fixed structure that the utility model provides, comprise seat board 1 and sand box 2, bottom, described sand box 2 both sides is all connected with the limiting plate 3 of rectangle, limiting plate 3 has a cam through hole 7, described seat board 1 has the manhole 9 aligned with cam through hole 7 great Duan center, also comprise the rotating shaft 4 that top is connected with cam 6, this cam 6 matches with cam through hole 7 geomery and is placed in limiting plate 3 top, and rotating shaft 4 lower end is successively through cam through hole 7 and manhole 9.
Can pass rapidly through cam through hole 7 for the ease of cam 6, avoid frictional influence to depart from, be matched in clearance between described cam 6 and cam through hole 7, gap size is 0.5-1mm.
Rotate for the ease of drive shaft 4 and realize locking or unlock, described rotating shaft 4 bottom is connected with rotating handles 5.
For the ease of being extracted out from seat board 1 by sand box 2 and installing, described sand box 2 rear and front end is all connected with handle 8.
During use: sand box 2 when mounted, first rotated by rotating handles 5 drive shaft 4, after the cam on rotating shaft 4 top all aligns with the cam through hole 7 on limiting plate 3, can sand box 2 be placed on seat board 1 from top to bottom, after cam 6 passes from limiting plate 3 upper surface, rotating shaft 4 makes cam 6 and cam through hole 7 stagger and namely achieves the locking of sand box 2 again; Sand box 2 needs to change abrasive sand when namely needing dismounting, is reversely rotated by rotating handles 5 drive shaft 4, when cam 6 aligns with cam through hole 7, namely 8 upwards to be extracted out by sand box 2 by shaking hands, the abrasive sand namely in replaceable sand box 2.
