Detailed Description
The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings. It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict. For convenience of description, the words "upper", "lower", "left" and "right" in the following description are used only to indicate the correspondence between the upper, lower, left and right directions of the drawings themselves, and do not limit the structure.
As shown in fig. 1 to 4, the band saw blade tooth chamfering correction device provided in this embodiment includes a bracket 1, a first fixed roller 21, a second fixed roller 22, a movable roller 3, a first connecting shaft 4, a second connecting shaft 5, a movable block 6, a pressing plate 7, a fixed frame 8, a driving source 9, a limiting assembly 10, and a spacer 11.
One end of the bracket 1 is provided with a sliding cavity 111 (as shown in fig. 1 and 4), and the other end is inserted with the first connecting shaft 4. The fixing frame 8 is arranged at the side of the bracket 1 close to the sliding cavity 111. The axial lead of the first fixed roller 21 and the axial lead of the second fixed roller 22 are arranged in the same direction, and the second fixed roller 22 is positioned below the first fixed roller 21. The height positions of the first fixed roller 21 and the second fixed roller 22 on the first connecting shaft 4 and the distance between the first fixed roller and the second fixed roller are realized by a plurality of spacer bushes 11 sleeved on the first connecting shaft 4. By providing different numbers of spacers 11, the height of the second fixed roller 22 is adjusted to be located at the bottom of the saw blade 20, and the height of the first fixed roller 21 is adjusted to be located away from the tooth tips, so as to prevent the tooth tips from being hit (as shown in fig. 3). The second fixed roller 22 contacts the bottom of the saw blade to ensure that the bottom of the saw blade is not inclined to one side due to stress during rolling.
The movable block 6 is placed in the sliding cavity 111. The movable roller 3 is arranged in the movable block 6 through a second connecting shaft 5. The movable roll 3 is held at a set height by a plurality of spacers 11 provided on the second connecting shaft 5. The movable roll 3, the first fixed roll 21 and the second fixed roll 22 can also be kept in a horizontal position (i.e. the respective axes are arranged vertically) by the spacer 11, and the upper end surface of the movable roll 3 and the lower end surface of the first fixed roll 21 are parallel (as shown in fig. 3), preferably flush. So as to ensure that a shearing force is generated between the movable roller 3 and the first fixed roller 21 during the rolling process to correct the inverted teeth. The corners of the movable roller 3, the first fixed roller 21 and the second fixed roller 22 are provided with 0.1-0.5 mm round corners, so that the contact part of the rollers and the saw blade is in smooth transition, and obvious cutting marks at the rolling positions of the saw blade cannot be generated due to the cutting of the two rollers.
The driving source 9 is fixed on the fixed frame 8, and a driving rod of the driving source penetrates through the fixed frame 8 and extends into the sliding cavity 111 to be connected with the movable block 6. In the present embodiment, the driving source 9 is a hydraulic cylinder.
As shown in fig. 1 and 4, the number of the pressing plates 7 is two, the two ends of the movable block 6 are both provided, and the direction in which the movable block 6 is provided is parallel to the sliding direction of the movable block 6. Each pressing plate 7 is fixed on the support 1 through a bolt, and the pressing plates 7 are abutted to the movable blocks 6. The movable block 6 is limited by the pressing plate 7, so that a sliding groove with a guiding effect is formed between the movable block 6 and the support 1, and the movable block 6 can slide stably.
As shown in fig. 1 and 2, a limiting assembly 10 for limiting the sliding of the movable block 6 toward the first fixed roller 21 is further disposed on the movable block 6.
The limiting assembly 10 comprises a bolt 101 and a nut 102 arranged on the bolt 101. The bolt 101 penetrates through the fixed frame 8 to be connected with the movable block 6. The nut 102 is located on the outer side of the fixed frame 8 far away from the movable block 6.
When in use, the saw blade 20 is placed between the first fixed roller 21, the second fixed roller 22 and the movable roller 3 and attached to the round end surfaces of the first fixed roller 21 and the second fixed roller 22. At this time, the height positions of the first fixed roll 21 and the second fixed roll 22 are set positions (as shown in fig. 2).
The driving source 9 provides power through the hydraulic station, when the device is running, the oil cylinder piston (driving rod) extends to push the movable block 6 and the movable roller 3 to move towards the direction of the first fixed roller 21, when the movable roller 3 contacts with the saw blade 20 and generates a rightward thrust F (as shown in fig. 3), the right side of the saw blade at the moment is limited by the first fixed roller 21 and the second fixed roller 22, and under the action of the thrust F, the tooth chamfering amount is forcibly pressed, so that the purpose of correcting the tooth chamfering is realized.
The displacement of the movable roller 3 to the right (towards the first fixed roller 21) is ensured by the limiting component 10. And the limiting component 10 can adjust the limiting amount by adjusting the position of the nut 102 on the bolt 101, so as to control the final position of the rightward pushing of the movable roller 3, and thus, the tooth tips cannot be excessively rolled during rolling.
In addition, the oil pressure of the hydraulic cylinder is adjustable, and the inverted tooth quantity with different sizes can be rolled by adjusting different pressures, so that the purpose of correction is achieved.
The band saw blade tooth chamfering correcting device can roll the chamfering teeth of about 0.1mm to within 0.02mm through the structure and the adjustable function, and does not cause any damage to the tooth tips and quality problems such as cutter bending and the like.
