Referring to fig. 1-39, the embodiment provides a brush strip forming apparatus, which includes a frame 33, and a plurality of guide wheels 34, a steel strip pre-forming mechanism, a wire feeding mechanism, a wire pressing mechanism, and a steel strip shaping mechanism are disposed on the frame 33 along a steel strip conveying direction.

Wherein, a plurality of guide wheels 34 and the machine 33 are arranged in sequence along the steel belt conveying direction. As shown in fig. 13, in this embodiment, the number of guide wheels 34 is two, and the steel belt 38 can be sequentially wound around the upper and lower end faces of the two guide wheels 34. The steel belt 38 is guided by the two guide wheels 34, and the steel belt 38 sequentially bypasses the upper end wheel face and the lower end wheel face of the two guide wheels 34, so that the steel belt 38 has certain tension, and the steel belt 38 is prevented from being bent. Of course, the number of guide wheels 34 can also be three, four or more, while ensuring that the steel strip 38 is guided and tensioned. And in order to prevent the steel belt 38 from being separated from the guide wheel 34, a steel belt groove 341 is formed in the guide wheel 34 in the circumferential direction. Steel strip 38 snaps into steel strip groove 341 and around guide wheel 34. The steel belt 38 is limited by the two side groove walls of the steel belt groove 341.

After the steel strip 38 is guided and transported by the guide wheel 34, the steel strip 38 is transported to a steel strip preforming mechanism. The steel strip preforming mechanism comprises a mounting seat 35, and a preforming assembly 36 is arranged on the mounting seat 35.

In this embodiment, the preforming tool 36 includes three pairs of setting wheel sets 361 arranged in sequence along the conveying direction of the steel strip. Each pair of the sizing wheel sets 361 comprises a sizing cam 3601 and a sizing concave wheel 3602 which are matched with each other, and the sizing cam 3601 and the sizing concave wheel 3602 are both rotatably connected with the mounting seat 35. To facilitate subsequent assembly of the strip 38 with the abrasive filaments, the sizing cam 3601 is vertically above the sizing concave wheel 3602. As a specific driving method, please refer to fig. 4, 10 and 12, a driving motor 3603 is disposed on the mounting base 35. Each shaping cam 3601 is connected with a cam rotating shaft 3604, and each shaping concave wheel 3602 is connected with a concave wheel rotating shaft 3605. An output shaft of the driving motor 3603 is connected with a concave wheel rotating shaft 3605 in the third pair of shaping wheel sets 361. A second rotating shaft transmission gear 3608 is arranged on the concave wheel rotating shaft 3605, a first rotating shaft transmission gear 3607 is arranged on the cam rotating shaft 3604, and the first rotating shaft transmission gear 3607 and the second rotating shaft transmission gear 3608 in the same set of shaping wheel sets 361 are meshed with each other. When the driving motor 3603 drives the sheave rotating shaft 3605 in the third pair of sizing wheel sets 361 to rotate, the second rotating shaft transmission gear 3608 rotates to drive the first rotating shaft transmission gear 3607 to rotate, and then the cam rotating shaft 3604 is driven to rotate, so that the cam rotating shaft 3604 and the sheave rotating shaft 3605 synchronously rotate in the opposite direction.

Meanwhile, the cam rotating shaft 3604 or the concave wheel rotating shaft 3605 in the two adjacent pairs of shaping wheel sets 361 are in transmission connection through gears. Specifically, in the present solution, as shown in fig. 10, a transmission rotating shaft 3609 is disposed on the mounting seat 35, a third rotating shaft transmission gear 3610 is disposed on the transmission rotating shaft 3609, and a second rotating shaft transmission gear 3608 on a concave wheel rotating shaft 3605 in two adjacent pairs of sizing wheel sets 361 is in gear transmission connection through the third rotating shaft transmission gear 3610, so as to implement synchronous rotation of the three pairs of sizing wheel sets 361.

In this embodiment, a cavity 3501 is formed inside the mounting seat 35, the cam rotating shaft 3604 and the concave wheel rotating shaft 3605 both penetrate through a side wall of the mounting seat 35 and extend into the cavity 3501, the first rotating shaft transmission gear 3607 and the second rotating shaft transmission gear 3608 are both located in the cavity 3501, and the transmission rotating shaft 3609 and the third rotating shaft transmission gear 3610 are also located in the cavity 3501. The cavity 3501 in the mounting seat 35 accommodates the first rotating shaft transmission gear 3607, the second rotating shaft transmission gear 3608 and the third rotating shaft transmission gear 3610, so that dust is prevented from falling into teeth of two adjacent gears to influence meshing of the gears.

It should be noted that although in the present embodiment, the output shaft of the driving motor 3603 is connected to the caster rotating shaft 3605 of the third pair of sizing wheel sets 361, the output shaft of the driving motor 3603 is connected to the cam rotating shaft 3604 or the caster rotating shaft 3605 of any one of the preforming assemblies 36 under the condition that the three pairs of sizing wheel sets 361 are synchronously rotated. And it is also possible that the cam shafts 3604 in two adjacent preform assemblies 36 are connected by a gear drive.

It should be noted that the fixing cam 3601 described in this embodiment is not a cam with an irregular wheel wall. The shaping cam 3601 in this embodiment is a disk-shaped wheel body, and a convex ridge 3611 is arranged on a wheel wall of the shaping cam 3601 along the circumferential direction. And the wall of the shaping concave wheel 3602 is circumferentially provided with a shaping groove 3612 matched with the convex ridge 3611. Because the protruding ridges 3611 are matched with the shaping grooves 3612, the width of the protruding ridges 3611 is reduced along the conveying direction of the steel belt, and the width of the opposite shaping grooves 3612 is also reduced along the conveying direction of the steel belt. Specifically, as shown in fig. 4 to 6, the cross section of the convex ridge 3611 on the sizing cam 3601 located at the head end position in the steel strip conveying direction is an inverted trapezoid, and the convex ridge 3611 is connected with the wheel wall of the sizing cam 3601 at the top edge of the inverted trapezoid. The width of the top edge of the inverted trapezoid is sequentially reduced along the conveying direction of the steel strip, and the included angle between the top edge and the side edge of the inverted trapezoid is sequentially increased.

When the steel belt 38 is guided by the guide wheel 34 and inserted into the shaping groove 3612 of the first pair of shaping wheel sets 361, the driving motor 3603 drives the shaping cam 3601 and the shaping concave wheel 3602 to synchronously and reversely rotate, the convex ridge 3611 and the shaping groove 3612 are mutually matched to carry out extrusion forming on the steel belt 38, in the forming process, the convex ridge 3611 and the shaping groove 3612 are respectively contacted with the upper belt surface and the lower belt surface of the steel belt 38, the steel belt 38 is driven by friction force to move forward to the next pair of shaping wheel sets 361 to carry out extrusion forming again until the steel belt 38 passes through the preforming mechanism to complete multi-section extrusion forming action, and the preformed steel belt 38 is obtained.

In this embodiment, as shown in fig. 5 and 6, a shaping protrusion 3613 is disposed on a bottom of the shaping groove 3612 of the shaping concave wheel 3602 in the second pair and the third pair of pre-forming assemblies 36, and an avoiding groove 3614 adapted to the shaping protrusion 3613 is disposed on the convex edge 3611 along a circumferential direction. The height of the shaping protrusions 3613 is sequentially increased along the conveying direction of the steel strip, and correspondingly, the groove width and the groove depth of the avoiding grooves 3614 are increased correspondingly.

When the steel strip 38 passes through the first pair of pre-forming assemblies 36, the steel strip 38 is pressed by the matching of the shaping protrusions 3613 and the shaping grooves 3612 in the first pair of pre-forming assemblies 36, and two sides of the steel strip 38 are pressed to form flanges 3802, so that flange grooves 3803 are formed on the steel strip 38, and the steel strip shown in fig. 7 is obtained. When the steel strip 38 continues to advance until passing through the second pair of pre-forming assemblies 36, the shaping protrusion 3613 on the bottom of the shaping groove 3612 forces the bottom of the steel strip 38 to be concave in the process of continuously extruding and overturning the flanges at two sides of the steel strip 38, and the bottom protrusion 3801 is formed by matching with the avoiding groove 3614, so that the steel strip 38 shown in fig. 8 is obtained. The strip 38 continues to advance until it passes through the third pair of pre-forming assemblies 36, resulting in the strip 38 shown in FIG. 9 (i.e., the pre-formed strip 38). The steel belt 38 is extruded and formed for multiple times through the multiple groups of convex ridges 3611 and the shaping grooves 3612, so that the problem that the steel belt 38 is damaged in the forming process of the steel belt 38 is solved. And the bottom of the steel belt 38 protrudes inwards to form a special-shaped part by matching the shaping protrusion 3613 with the avoiding groove 3614, so that the structural strength is improved, and the steel belt 38 is high in structural strength after being formed and is not easy to deform. Meanwhile, the contact area between the bottom of the steel belt 38 and the outer wall of the phosphorus breaking roller is increased due to the fact that the bottom of the steel belt 38 is sunken inwards, stability of the steel belt 38 arranged on the outer wall of the phosphorus breaking roller is improved, and the steel belt 38 is prevented from being inclined when arranged on the outer wall of the phosphorus breaking roller.

However, in this embodiment, the groove bottom of the shaping groove 3612 in the first pair of shaping wheel sets 361 at the head end of the steel strip conveying direction is not provided with the shaping protrusion 3613, and the convex ridge 3611 in the same shaping wheel set 361 is not provided with the avoiding groove 3614. The sizing protrusions 3613 are not arranged at the bottoms of the sizing grooves 3612 in the first pair of sizing wheel sets 361, so that the steel belt 38 is prevented from deviating due to the fact that the sizing protrusions 3613 deviate from preset forming positions when the steel belt 38 is formed for the first time. After the steel belt 38 is preformed for the first time through the first pair of shaping wheel sets 361, bottom shaping is carried out through the shaping protrusions 3613 in the subsequent shaping wheel sets, and the function of preventing the steel belt 38 from deforming and deviating is achieved.

Although the number of the sizing wheel sets 361 is only three in the present embodiment, four, five, and five or more pairs may be used in the case of ensuring the molding of the steel strip 38. When the number of the shaping wheel sets 361 is four or five or more, the number of the shaping cams 3601 provided with the shaping protrusions 3613 is not limited in the case of ensuring the shaping of the bottom protrusions 3801 of the steel strip 38.

And in an embodiment, the shaping cam 3601 is detachably connected with the cam rotating shaft 3604. Specifically, as shown in fig. 4-6, the shaping cam 3601 is sleeved on the cam rotating shaft 3604, and a first limiting plate 3615 is disposed on one side of the shaping cam 3601. The first limiting plate 3615 is provided with a bolt, and is detachably connected with the cam rotating shaft 3604 through the bolt. The other side of the sizing cam 3601 is provided with a cam limiting part, in this scheme, the cam limiting part is a cam limiting sleeve 3616, the cam limiting sleeve 3616 is sleeved on the cam rotating shaft 3604, and two ends of the cam limiting sleeve 3616 respectively abut against the mounting seat 35 and the sizing cam 3601 to realize fixation. The shaping cam 3601 is clamped between the first limit plate 3615 and the cam limit sleeve 3616 to realize axial fixed connection with the cam rotating shaft 3604. It is easy to understand, because the steel band 38 is driven to move forward through frictional force between protruding stupefied 3611 and the steel band 38, the outer wall of protruding stupefied 3611 has certain wearing and tearing, and after protruding stupefied 3611 weares and teares, can turn round the bolt, dismantle first limiting plate 3615, accomplish the dismouting of design cam 3601.

Similarly, the shaping concave wheel 3602 is sleeved on the concave wheel rotating shaft 3605, and a second limiting plate 3617 is arranged on one side of the shaping concave wheel 3602. The second limiting plate 3617 is detachably connected with the concave wheel rotating shaft 3605 through bolts. The other side of the shaping concave wheel 3602 is provided with a concave wheel limiting part. The concave wheel limiting part is a concave wheel limiting sleeve 3618 in the scheme. The concave wheel limiting sleeve 3618 is sleeved on the concave wheel rotating shaft 3605, and two ends of the concave wheel limiting sleeve 3618 are respectively abutted against the mounting seat 35 and the shaping concave wheel 3602 to achieve fixing. The shaping concave wheel 3602 is clamped between the second limit plate 3617 and the concave wheel limit sleeve 3618 to realize axial fixed connection with the concave wheel rotating shaft 3605.

In addition, as shown in fig. 14, a protective cover 37 is further provided on the mounting seat 35, and the preforming module 36 is provided in the protective cover 37 to prevent dust from falling between the sizing cam 3601 and the sizing dented wheel 3602 to affect the forming of the steel strip 38. And both sides of the shield cover 37 are provided with openings to facilitate the passage of the steel belt 38.

In the present embodiment, please refer to fig. 15-20, the wire feeding mechanism includes a fixing base 39, and the fixing base 39 is disposed on the frame 33. In this embodiment, the fixing seat 39 is divided into two plates, and the two plates are respectively located at two sides of the mounting seat 35. It will be appreciated that the mounting base 39 may be formed as a single integral piece without interfering with the mounting base 35 and the components of the mounting base 35.

And a plurality of supporting belt wheels 5 are arranged on the fixed seat 39, and a belt 13 is wound on the supporting belt wheels 5. And the belt 13 carries abrasive wires 4, the length direction of the abrasive wires 4 being in line with the width direction of the belt 13. The belt 13 carries the abrasive material in the direction of the pre-formed steel strip 38. In this scheme, the number of belt 13 is two, and two belt 13 are parallel to each other. The head end and the tail end of the belt 13 are connected, and are supported by a plurality of supporting belt wheels 5 to form a closed belt path. The belt 13 is divided into a horizontal conveying section 1301 and a vertical conveying section 1302 in the conveying direction, and the belt 13 conveys the abrasive filament 4 on the vertical conveying section 1302 from top to bottom in the vertical direction. And in this embodiment, preformed steel strip 38, extruded by the steel strip 38 preforming mechanism, passes between the two belts 13 on vertical transport section 1302. When the belt 13 transports the abrasive filament 4 from top to bottom on the vertical transport section 1302, the abrasive filament 4 can just fall onto the preformed steel belt 38, and is supported and transported by the preformed steel belt 38.
