The utility model compared with prior art, advantage is: structure is ingenious, compact, rationally, can guarantee the balancing tension of steel wire in drawing, wrapup procedure, reaches main frame and admission machine run-in synchronism; Guarantee that simultaneously steel wire is not broken and sleave in wrapup procedure.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the structure side cutaway view of the utility model.
The specific embodiment
Below in conjunction with concrete accompanying drawing and embodiment the utility model is described further.
Said traction attitude reference device is used for guaranteeing the balancing tension of steel wire A at drawing, wrapup procedure, reaches main frame and admission machine run-in synchronism; Guarantee that simultaneously steel wire A is not broken and sleave in wrapup procedure.
As shown in the figure, said traction attitude reference device mainly is made up of tumbler shaft 1, connecting rod 2, buffer bar 4, cushion pad 5, driving wheel 6, support 7, fixed wheel 8, roller shaft 10, nut 11, induction support 12, sensor 13, parts such as induction cam 14, bearing block 15 and fixed axis 16.
Like Fig. 1, shown in Figure 2, bearing block 15 utilizes screw to be fixed on the casing of wire drawing machine, and tumbler shaft 1 is installed in rotation in the bearing block 15 through bearing and hole back-up ring; Connecting rod 2 one ends are connected the front end of tumbler shaft 1 and fix through screw; Connecting rod 2 other ends are equipped with roller shaft 10; Roller shaft 10 is through nut 11 and tight, and two driving wheels 6 are installed in rotation on the roller shaft 10 through bearing and hole back-up ring, utilize back-up ring to be separated by between two driving wheels 6; The top of said casing is installed with support 7 through screw, through screw 16, three fixed wheels 8 of fixed axis is installed on the support 7 and is installed in rotation on the fixed axis 16 through bearing and hole back-up ring, utilizes back-up ring to be separated by between the adjacent fixed wheel 8.
As shown in Figure 2, an induction cam 14 is equipped with in the rear end of said tumbler shaft 1, and induction cam 14 utilizes holding screw to be fixed on the tumbler shaft 1, follows tumbler shaft 1 and rotates synchronously; Said casing rear side is equipped with induction support 12; Induction is equipped with sensor 13 on the support 12, and when steel wire A occurring and broken situation, driving wheel 6 drops to extreme lower position at once; Induction cam 14 contacts with sensor 13, and sensor 13 provides signal to electric-control system and stops.
Like Fig. 1, shown in Figure 2, the last buffer unit 9 and following buffer unit 3 that are used for limiting rod 2 rotational angles and play cushioning effect are installed on the leading flank of said casing.Said upward buffer unit 9 is identical with following buffer unit 3 structures, and they all are made up of buffer bar 4 and cushion pad 5, and buffer bar 4 is fixed on the casing leading flank through screw, and cushion pad 5 is fixed on buffer bar 4 front ends through screw.Said position of going up buffer unit 9 and following buffer unit 3 can be provided with according to concrete technological requirement flexibly, and the angle between the last buffer unit 9 in the utility model and following buffer unit 3 and the tumbler shaft 1 is 60 °.
In the utility model, driving wheel 6 quantity on the roller shaft 10 and fixed wheel 8 quantity on the fixed axis 16 are not limited to the number shown in the figure, and it can be according to concrete technological requirement increase and decrease, as long as keep fixed wheel 8 quantity to Duo one than driving wheel 6 quantity.
During concrete the application, steel wire A twines one to three circle between fixed wheel 8 and driving wheel 6, make driving wheel 6 do less swinging up and down at horizontal level, guarantees front and back steel wire A balancing tension, reaches the purpose of normal rolling.Broken like steel wire A, driving wheel 6 drops to extreme lower position at once, provides signal to electric-control system through sensor 13 and stops, and can not start once more, after troubleshooting finishes to reset, could start.
