The joggling device is compsoed of three rollers, an upper guide plate, a lower guide plate and guide strips. An upper roller is respectively engaged with two lower rollers. The guide strips which are provided with two slant surfaces of dummy club are inlaid in the upper guide plate, the lower guide plate, and the groove of the front-lower roller. Compared with an existing joggling device for thin-strip material, the edge of the strip material of the utility model can hardly be torn or be crumpled. The utility model can be conveniently used for processing strip material with different widths. The raw material can be saved.

Description

Joggling equipment for thin-strip material

The utility model relates to a kind of crimping equipment of processing the strip material, in particular for making the crimping equipment of automobile radiators fin.

In existing technology, the strip material is to finish the crimping operation by equipment shown in Figure 1.This equipment by front guide pay 2, front roller wheel pays 3, back guide 5, back guide groove 7, rear roll pay 6 and bridge wheel 4 form.Its operation process as shown in Figure 2, band material 1 is paid guiding in 2 at front guide, pay 3 by running roller after, band material both sides are converted into 90, in back guide 5 and back guide groove 7, flanging forms 20 ° of angles with the band material, is pressed into rugosity at last in rear roll is paid.

Because the 1st distortion of band material 1 is to rely on front roller wheel to pay 3 the wide b ' of roller to guarantee that the band material different to width must be changed the running roller of different in width and could work, versatility is relatively poor.In addition, because band material 1 reaches about 1/2nd of band material surface area with the contact-making surface of back guide 5, and from front roller wheel pay 3 to very long scope between the rear roll 6 (see figure 1), each position of band material 1 all has been subjected to the clamping action power of back guide 5 and back guide groove 7, make the motion of band material be subjected to very big frictional resistance, and the situation of edge break, fold even interruption of work so take place in band material marginal portion stressed maximum easily.Usually have only by increasing flanging height h, reduce nip stress, could guarantee that everything goes well with your work carries out.

Task of the present utility model provides a kind of band that can reduce and expects edge break and fold, reduces height of flange h, can be applicable to the strip material crimping equipment of the band material processing of different in width easily.

Task of the present utility model is finished in the following manner: promptly this crimping equipment is by 3 rolls and upper guide plate, and bottom guide and sliver are formed.Topping roll meshes with two bottom rolls respectively, and the sliver that is processed with two boss inclined-planes is embedded in the groove of bottom guide and preceding bottom roll.

The surface of the last bottom guide of this crimping equipment and the circumferential surface of preceding bottom roll radially are processed with some grooves.The 1st boss inclined-plane on the sliver and 30～60 ° of angles of vertical bus clip of sliver, and with 30～60 ° of angles of working face folder of sliver, all towards the direction of motion inclination of band material.The 2nd the boss inclined-plane on the sliver and the angle of zone face gradually become 20～0 ° along the direction of motion of band material from 90 °.

Embodiment:

With reference to Fig. 4,5,6,7,8,9,10, strip material crimping equipment comprises 3

rolls

4,6,8, roll 4 meshes with roll 8 and roll 6 respectively, upper guide plate 3, on the surface of bottom guide 10 and the circumferential surface of roll 8 radially be processed with 5 sliver grooves, sliver 2 is embedded in upper guide plate 3, in the groove of bottom guide 10 and roll 8.Be processed with boss inclined-plane 9 and boss inclined-plane 7 on the sliver 2, vertical bus clip 45 of boss inclined-plane 9 and sliver 2, and with the working face folder 45 of sliver 2, all towards the direction of motion inclination of band material 1; Boss inclined-plane 7 and zone face angle gradually become 20 ° along the direction of motion of band material 1 from 90 °, at this moment, and long 6 millimeters of the adjacent side of angle.

Strip material 1 is subjected to the traction of

roll

4,6,8, and its edge is at first depressed by the boss inclined-plane 9 on the raised line 2, and finishes 90 ° upset (as Fig. 5-II shape) in the slit 11 that is formed by sliver 2 and bottom guide 10; Then, finish 20 ° upset (as Fig. 5-III shape) in the slit that band material 1 is made up of the inclined-plane 7 of sliver 2 terminations and running roller 4; At last, in the roll compacting of 5 places, crimping is folded into the shape of Fig. 5-IV by roll 4 and roll 6.

In the utility model, be with the most surfaces of expecting to be close to the roll constant speed and move in the same way, only the side and the sliver 2 of band material 1 have the very little rubbing surface of an area, and frictional resistance is reduced greatly.In addition, band material 1 is stretched on the curved surface of roll 4, because curved surface twines the effect of power, zone face does not need pressing plate, just can be adjacent to And naturally and increase the tractive force of roll effectively the band material, crimping 12 breaker rolls 4 have tension force, naturally it is identical with the direction of tractive force at 7 places, boss inclined-plane of sliver 2 to be folded to zone face ， And, thereby has reduced the frictional force of boss inclined-plane 7 pairs of band material side, make marginal laceration, the danger of fold reduces, and then the height of flange h of band material can correspondingly reduce (the flanging height of automobile radiators band material can be reduced to 1 millimeter by original 2.5 millimeters), has saved certain raw material.

In addition, because sliver 2 of the present utility model is to be embedded in the groove of upper guide plate 3, bottom guide 10 and roll 8, so, when needs change band material width b, as long as sliver 2 is moved in the corresponding sliver groove, can adapt to the band material processing of different size easily.
