Abstract
The utility model relates to a first structure of wire drawing, including the wire drawing wheel, its characterized in that the wire drawing wheel is connected on the wire drawing pole the wire drawing pole passes through the connecting axle rotation to be connected on the fixing base, and, the fixing base with still be equipped with both relative position's of instant regulation elastic component between the wire drawing pole. It is better, the elastic component is the torsional spring. Compared with the prior art, the utility model provides a first structure of wire drawing can be in the drawing process, according to workpiece surface's particular case, adjust the position of wire drawing head immediately through the elastic component, makes wire drawing head even application of force all the time in whole drawing process, has guaranteed drawing quality, and the product yields is high.
Description
Technical field
The present invention relates to a kind of drawing head structure.
Background technology
In order to make the outward appearance of product more beautiful, have more characteristic, bronze appearance member after processing is completed, needs to carry out wire drawing thereon usually, forms wire drawing texture, meets the ornamental requirement of people better.
Carry out wire drawing to bronze appearance member in prior art, normally will treat that wire drawing part is placed on revolving body, revolving body rotates drive and treats that wire drawing part rotates, and treats that the wire drawing position of wire drawing part rubs on drawing head, is treating wire drawing part forms wire drawing after rotating a circle.
In drawing process, treat the structural defect of wire drawing part, such as treat the uneven of wire drawing part surface, and the deviation of concentricity during the rotation of revolving body, wire drawing all can be caused uneven, depression position draw less than, then wire drawing is excessive at the position of evagination, and expose the copper background color of bottom, production yields is low, the workpiece that wire drawing is scrapped needs to return copper facing operation and does over again, and causes production cost to increase.
Summary of the invention
Technical problem to be solved by this invention provides a kind of drawing head structure carrying out even wire drawing to surface of the work for the present situation of prior art, thus reach ensure wire drawing quality, avoid workpiece to do over again, the object of production cost of enhancing productivity, reduce.
The present invention solves the problems of the technologies described above adopted technical scheme: this drawing head structure, comprise pulling wheel, it is characterized in that described pulling wheel is connected on wire drawing bar, described wire drawing bar is rotatably connected on holder by connecting axle, further, the elastic component of both instant adjustments relative position is also provided with between described holder and described wire drawing bar.
Described elastic component is torsion spring, and described torsion spring set is located on described connecting axle, conflicts respectively on described wire drawing bar and described holder in the two ends of torsion spring.
Described wire drawing bar is provided with Connection Block, and described holder is provided with slot, and described Connection Block is plugged in slot, and both are rotatably connected through two sidewalls of described Connection Block and described slot by described connecting axle.
Described holder is also provided with for limiting the spacer pin of described Connection Block relative to holder rotational angle.
Described holder is connected on the piston rod of piston cylinder.
Compared with prior art, drawing head structure provided by the present invention can in drawing process, according to the concrete condition of surface of the work, immediately the position of drawing head is adjusted by elastic component, drawing head evenly can be exerted a force all the time in whole drawing process, ensure that wire drawing quality, product yields is high.
Accompanying drawing explanation
Fig. 1 is the utility model embodiment using state schematic perspective view;
Fig. 2 is the decomposing schematic representation of the utility model embodiment.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the present invention is described in further detail.
As depicted in figs. 1 and 2, this drawing head structure comprises:
Pulling wheel 1 is prior art, can select any one pulling wheel structure of the prior art as required.
Wire drawing bar 2, comprises connecting rod 22 and Connection Block 21, and one end of connecting rod 22 is used for fixing pulling wheel 1, and the other end of connecting rod connects Connection Block 21.Connection Block 21 in the present embodiment is " recessed " character form structure, and its bottom surface connects connecting rod 22, and its two sides are provided with the first axis hole 23.
Holder 4, its one end connects the piston rod 7 of cylinder, and the other end is provided with the slot 41 suitable with Connection Block, the two sides of slot 41 is interval with the second axis hole 42 and pin-and-hole 43.Connection Block 21 is plugged in slot 41.
Connecting axle 3, through the second axis hole and the first axis hole, is rotatably connected on wire drawing bar on holder 4.
Spacer pin 6, is plugged in two pin-and-holes 43, for limiting the rotational angle of Connection Block relative to holder, thus limits the rotational angle of wire drawing bar.
Elastic component 5, is arranged between Connection Block 21 and holder 4, and for immediately adjusting the position of pulling wheel, compensate the wire drawing power inequality that surface of the work out-of-flatness causes, the elastic component 5 in the present embodiment is torsion spring.Torsion spring set is located on connecting axle 3, conflicts respectively on the bottom surface of Connection Block and the bottom surface of slot in the two ends of torsion spring.
The operation principle of this drawing head structure is described below:
To treat that wire drawing workpiece 8 is fixed on revolving body 9, cylinder (not shown) works, holder, wire drawing bar and drawing head are pushed to operating position by piston rod 7, revolving body 9 rotates, driving treats that wire drawing workpiece 8 rotates, pulling wheel 1 and treat to produce between wire drawing workpiece to rub, thus treating that wire drawing surface of the work forms wire drawing lines.
In drawing process, run into revolving body generation to beat, or treat the situation of wire drawing workpiece surface irregularity, under the cushioning effect of elastic component, the spring energy of elastic component compensates the change of the wire drawing power that above-mentioned defect causes immediately, makes pulling wheel and treats that between wire drawing workpiece, frictional force remains in claimed range, eliminate because workpiece turns round the drawback that wire drawing lines fluctuates, lines is deep mixed of beating and producing, ensure that the yields of drawn wire product, reduce production cost, improve production efficiency.
