Description

Technical Field

[0001] This utility model relates to the field of band saw blade tooth splitting technology, and in particular to a tooth feeding mechanism for band saw blade tooth splitting. Background Technology

[0002] Split teeth are designed to deflect the saw teeth to opposite sides, making them not on the same plane. The main purpose is to reduce the friction between the kerf and the saw blade, preventing the saw blade from getting stuck or breaking. This design not only helps improve the sawing effect, but also protects the saw blade and extends its service life.

[0003] The band saw blade feeding mechanism is paired with the tooth splitting mechanism. Most existing tooth feeding mechanisms use a clamp to hold the band saw blade and then a cylinder to move the clamp to feed the teeth. This has the following problems: First, during the processing of the band saw blade teeth, the entire band saw blade is exposed on the substrate. Since the band saw blade is normally coiled in a disc shape, it has a small curvature when unfolded. During the tooth splitting process, at least two sets of clamps are needed to ensure that the band saw blade is straight during the tooth splitting process. Second, existing tooth feeding mechanisms mostly push the band saw blade by having a pusher contact the root of the saw teeth. Since there are differences in the tooth pitch of different saw blades, the pusher mechanism needs to be readjusted and calibrated when changing to different specifications of saw blades. Otherwise, the pusher will contact the tooth tip, which may cause the tooth tip to bend or even break.

[0004] In view of this, there is an urgent need for a tooth feeding mechanism for band saw blade tooth splitting to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0025] Clearly, the described embodiments are merely a part of the embodiments of the present utility model, rather than all the embodiments.

[0026] Embodiment one

[0027] Please refer to the accompanying Figures 1-4 A tooth feeding mechanism for band saw blade tooth separation, comprising:

[0028] The base plate 1 is provided with a sliding rail 10 and a sliding groove 11, the bottom wall of the movable plate 2 is provided with a second sliding groove 20 matched with the sliding rail 10, the tooth separation assembly 3 comprises a tooth separation die 30 and a first air cylinder 31, the tooth separation die 30 is detachably connected to the adjacent side walls of the two groups of movable plates 2 in a symmetrical position respectively, the first air cylinder 31 is fixedly connected to a fixed part, and the piston rod of the first air cylinder 31 is fixedly connected to the side wall of the movable plate 2 away from the tooth separation die 30, and the tooth feeding mechanism 4 is slidingly connected with the sliding groove 11.

[0029] The first air cylinder 31 drives the two groups of movable plates 2 and the tooth separation dies 30 thereon to move, thereby realizing contact with the sawtooth part of the band saw blade and completing the tooth separation operation, at the same time, in order to avoid the inclination of the movable plate 2 due to its large size during displacement, the sliding rail 10 and the second sliding groove 20 on the movable plate 2 are used to correct the position of the movable plate 2, and after the tooth separation assembly 3 completes single tooth separation, the tooth feeding mechanism 4 moves the band saw blade, so that the tooth separation assembly 3 can contact and separate the other sawtooth.

[0030] Considering that if the band saw blade itself is not effectively fixed during the tooth separation process, the tooth separation die 30 will only tilt after contacting the band saw blade, and in this case, the sawtooth cannot be effectively separated, therefore, an assembly needs to be set to fix the band saw blade, specifically, the base plate 1 is provided with an auxiliary clamping groove 12 consistent with the advancing direction of the band saw blade, the auxiliary clamping groove 12 is provided with a clamp replacement groove 13 matched with the position of the tooth separation die 30, and the clamp replacement groove 13 is provided with an adaptive clamp 14 detachably connected thereto; at the same time, considering that there are many specifications of band saw blades in actual application, a single width of auxiliary clamping groove 12 cannot meet most specifications of band saw blades, therefore, the clamp replacement groove 13 and the adaptive clamp 14 matched with the clamp replacement groove 13 are arranged at the position of the tooth separation die 30, wherein the adaptive clamp is provided with a clamping groove consistent with the function of the auxiliary clamping groove 12 but smaller in width than the auxiliary clamping groove 12.

[0031] Specifically, the tooth feeding mechanism 4 comprises a column 40, a transverse plate 41, a tooth feeding assembly 42, a second air cylinder 43 and an auxiliary assembly 44, the column 40 is slidingly connected in the sliding groove 11, the second air cylinder 43 is fixedly connected on the base plate 1, the piston rod thereof is fixedly connected on the side wall of the column 40, the second air cylinder 43 is in the same direction as the column 40, the transverse plate 41 is fixedly connected on the upper end of the side wall of the column 40 close to the auxiliary clamping groove 12, the mounting through hole 410 is arranged on the transverse plate 41, the tooth feeding assembly 42 is movably connected with the mounting through hole 410, the auxiliary assembly 44 is arranged between the column 40 and the tooth feeding assembly 42, and is fixedly connected on the base plate 1 and movably connected with the tooth feeding assembly 42.

[0032] The column 40 is driven by the second air cylinder 43 to slide in the sliding groove 11, and then the transverse plate 41 and the tooth feeding assembly 42 are driven by the column 40 to move, and it should be noted that the second air cylinder 43 can only achieve the purpose of driving the tooth feeding assembly 42 to move, and the position thereof is not limited on the base plate 1.

[0033] Considering that different specifications of band saw blades have different heights in actual application, the tooth feeding assembly needs to be adjusted accordingly in this case, and specifically, the tooth feeding assembly 42 comprises a screw rod 420, at least two groups of nuts 421, a connecting block 422, an L-shaped plate 423, a rocker plate 424, a sleeve 425, a sleeve rod 426 and a tooth feeding die 427, the upper end of the screw rod 420 is connected with another nut 421 after penetrating through one of the nuts 421 and the mounting through hole 410, the lower end of the screw rod 420 is fixedly connected with the connecting block 422, one end of the L-shaped plate 423 is fixedly connected to the bottom wall of the connecting block 422, and the end, away from the connecting block 422, of the L-shaped plate 423 is provided with a mounting groove 4230, one end of the rocker plate 424 is rotatably connected in the mounting groove 4230, and the other end is fixedly connected to the side wall of the sleeve 425, the upper end of the sleeve rod 426 is threadedly connected with the sleeve 425, and the lower end is fixedly connected with the tooth feeding die 427.

[0034] The two groups of nuts 421 are respectively arranged on the two sides of the transverse plate 41, when the nuts 421 are adjusted to be respectively arranged at different positions of the screw rod 420, the actual use position of the screw rod 420 can be adjusted, and the position of the connecting block 422 is adjusted, thereby indirectly increasing the application range of the tooth feeding assembly 42, the rocker plate 424 is arranged in the mounting groove 4230 arranged on the end, away from the connecting block 422, of the L-shaped plate 423, and it should be noted that the rocker plate 424 is connected with the mounting groove 4230 through a torsional spring, that is, the rocker plate can swing slightly in the bearing, and the swinging amplitude can be determined according to the specification of the band saw blade, and the swinging amplitude can be adjusted, such as the specification of the band saw blade is 20mm, the swinging amplitude of the rocker plate is 5mm, and the specification of the band saw blade is 30mm, the swinging amplitude of the rocker plate is 10mm. Figure 2The preset adjusting handle and the torsional spring connection enable the rocker plate 424 to return to its initial position without external force, which ensures that the rocker plate 424 can contact the band saw blade to complete the tooth feeding process when the sleeve rod 426 and the tooth feeding die 427 at the lower end of the sleeve rod 426 are driven by the sleeve 425 to feed the teeth under the action of the second cylinder 43, and the rocker plate 424 can also be slightly swung to be separated from the band saw blade when the second cylinder 43 is retracted, thereby avoiding wear on the saw teeth.

[0035] In view of the problem that the tooth feeding assembly 42 may contact the saw teeth and cause wear on the saw teeth during the retraction of the second cylinder 43 without any assistance, an auxiliary assembly 44 is provided to further solve the above problem. Specifically, the auxiliary assembly 44 includes a U-shaped fixing frame 440, a Y-shaped fork 441, a rotating disc 442, and a rotating rod 443. The U-shaped fixing frame 440 is fixedly connected to the base plate 1. The lower end of the Y-shaped fork 441 is connected to the U-shaped fixing frame 440 through a torsional spring. The upper end of the Y-shaped fork 441 is provided with a rotating groove 4410 matched with the rotating disc 442. The rotating disc 442 is movably connected in the rotating groove 4410. One end of the rotating rod 443 is connected to the rotating disc 442 through a bearing, and the other end is fixedly connected to the side wall of the sleeve 425. When the second cylinder 43 drives the tooth feeding assembly 42 to move towards the tooth separating die 30, the rotating rod 443 drives the rotating handle 442 to exert an external force on the U-shaped fixing frame 440, thereby rotating the Y-shaped fork 441 with the U-shaped fixing frame 440 as the center of rotation. At the same time, the Y-shaped fork 441 assists the rocker plate 424 in swinging and feeding teeth by using the reaction force of the Y-shaped fork 441. It should be noted that the rotating direction and the direction of the reaction force of the Y-shaped fork 441 are different when the relative positions of the Y-shaped fork 441 and the rocker plate 424 are different. Therefore, in actual application, the Y-shaped fork 441 and the U-shaped fixing frame 440 can be connected through a torsional spring, and the direction of the force acting on the rocker plate 424 can be adjusted by adjusting the initial position of the Y-shaped fork 441, so as to achieve the purpose of exerting a downward pressure on the rocker plate 424 to make it contact the saw teeth when the rocker plate 424 feeds teeth, and exerting an upward force on the rocker plate 424 to make it separate from the saw teeth when the rocker plate 424 returns to its initial position after feeding teeth.

[0036] The whole tooth feeding and splitting process is as follows: after the second cylinder 43 is started, the piston rod drives the column 40 to move towards the splitting die 30. During the movement, the sleeve 425 will apply an external force to the rotating disc 442 through the rotating rod 443 fixedly connected thereto. After the force on the rotating disc 442 is transmitted to the Y-shaped fork 441, the Y-shaped fork 441 will rotate around the U-shaped fixed frame 440 as the center of rotation, and will exert a torsional force on the torsional spring during the rotation. At the same time, when the Y-shaped fork 441 rotates, the rotating disc 442 will also slide along the rotating groove 4410, and the elastic force generated by the torsional spring will be directly transmitted to the sleeve 425 through the Y-shaped fork 441 and the rotating rod 442. The reverse force transmitted to the sleeve 425 by the rotating rod 443 will drive the rocker plate 424 to rotate towards the band saw blade, so that the tooth feeding die 427 at the lower end of the sleeve rod 426 is in contact with the band saw blade. At this time, a part of the tooth feeding die 427 will be embedded in the saw groove of the band saw blade, and will push the band saw blade to move towards the splitting die 30 under the action of the force of the second cylinder 43. Then, the splitting die 30 is driven by the first cylinder 31 to complete the splitting of the band saw blade. After the splitting is completed, the first cylinder 31 drives the splitting die 30 to return to the initial position, and the second cylinder 43 drives the column 40 to return to the initial position. During the process of returning to the initial position, the tooth feeding assembly 42 moves away from the splitting die 30, and at the same time, the Y-shaped fork 441 is driven by the rotating rod 443 and the rotating disc 442 to return to the initial position. During this process, the reverse force received by the sleeve 425 will drive the rocker plate 424 to rotate away from the band saw blade, thereby achieving the purpose of separating the tooth feeding die 427 from the band saw blade, so as to avoid damaging the saw teeth of the band saw blade during the resetting process of the tooth feeding mechanism 4.

[0037] Specifically, the bottom wall of the tooth feeding die 427 is provided with an arc-shaped tooth feeding column 4270 matched with the band saw blade. Considering that the tooth grooves between the saw teeth of most band saw blades are arc-shaped, an arc-shaped tooth feeding column matched with the tooth groove of the band saw blade is arranged on the bottom wall of the regular-shaped tooth feeding die 427.

[0038] Example Two

[0039] Please refer to the attached Figures 5-6

[0040] Considering the tooth feeding structure of the first embodiment, different molds need to be replaced according to different specifications of the band saw blade, and there is also the case of wear between the saw tooth and the mold in long-term work, for example, the staff's lack of experience causes the tooth feeding mechanism 4 to directly contact the tooth tip, and then causes the saw tooth to wear, so the tooth feeding mechanism 4 is further improved, specifically, the tooth feeding mechanism 4 includes a vertical column 40, a transverse plate 41, a second air cylinder 43 and a tooth feeding assembly two 6, the vertical column 40 is slidingly connected in the sliding groove 11, the second air cylinder 43 is fixedly connected to the base plate 1, the piston rod thereof is fixedly connected to the side wall of the vertical column 40, and the piston rod of the second air cylinder 43 is in the same direction as the sliding direction of the vertical column 40, the tooth feeding assembly two 6 includes a third air cylinder 60, a U-shaped clamp 61, two groups of clamping pieces 62 and two groups of springs 63, the third air cylinder 60 is fixedly connected to the top wall of the transverse plate 41, the piston rod of the third air cylinder 60 is fixedly connected to the U-shaped clamp 61 through the transverse plate 41, and the piston rod of the third air cylinder 60 is slidingly connected to the transverse plate 41, the two groups of clamping pieces 62 are hingedly connected to the opposite side walls of the U-shaped clamp 61 at the middle positions, and the two groups of springs 63 are fixedly connected to the inner walls of the U-shaped clamp 61 at one end and to the upper ends of the clamping pieces 62 at the other end;

[0041] When tooth feeding is needed, the U-shaped clamp is driven by the third air cylinder 60 to move towards the direction of the band saw blade, in this process, after the band saw blade passes between the two groups of clamping pieces 62, the body of the band saw blade will contact the upper ends of the clamping pieces 62 and press the springs 63 through the clamping pieces 62, at this time, the clamping pieces 62 will rotate due to the hinge, the lower ends of the clamping pieces 62 rotate towards the direction of the band saw blade and clamp the band saw blade, then the tooth feeding assembly two 6 clamping the band saw blade moves towards the direction of the tooth separating mold 30 under the drive of the second air cylinder 43, and the tooth feeding is completed, the above structure is suitable for processing band saw blades of multiple specifications and small batches, and the advantage is that tooth feeding is performed in a clamping manner, as long as the thickness difference of the band saw blades of multiple specifications and small batches is not large, the tooth feeding mechanism two 6 does not need to be adjusted multiple times when different band saw blades with different tooth pitches are replaced for processing.

[0042] In order to strengthen the clamping effect, the clamping piece is optimized, specifically, a plurality of spherical protrusions 620 are arranged on the lower end side wall of the clamping piece 62; in order to enhance the clamping effect of the clamping piece 62 on the band saw blade, a plurality of spherical protrusions 620 are arranged on the lower end of the clamping piece 62, so that the original surface contact of the clamping piece 62 with the band saw blade is replaced by multiple point contact, the contact area is reduced, and the clamping effect is enhanced.

[0043] The above merely describes a preferred embodiment of the present application, and the protection scope of the present application is not limited thereto, and any skilled person in the art, according to the technical scheme and the inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
