DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0024] Please refer to the drawings of the embodiments of the utility model Figures 1-4 A band saw blade tooth separating structure, comprising:

[0025] The substrate 1, two groups of movable plates 2, two groups of power assemblies 3 and two groups of tooth separating assemblies 4, at least one group of sliding grooves 20 is arranged on the movable plate 2, the slide rail 10 matched with the sliding groove 20 is arranged on the substrate 1, the power assembly 3 is movably connected with the substrate 1 and the movable plate 2 respectively, and two groups of tooth separating assemblies 4 are detachably connected to the adjacent side walls of two groups of movable plates 2.

[0026] The sliding groove 20 arranged on the movable plate 2 is matched with the slide rail 10 on the substrate 1, so that the movable plate 2 has a certain displacement space, two groups of movable plates 2 are driven to cross and displace by two groups of power assemblies 3, and the tooth separating assembly 4 on the movable plate 2 is driven to contact with the band saw blade by the movable plate 2, so as to realize the purpose of separating the teeth on the band saw blade.

[0027] Specifically, the substrate 1 is provided with two groups of positionally symmetrical longitudinal grooves 12 and two groups of positionally symmetrical transverse grooves 13, and one end of the longitudinal groove 12 is communicated with the transverse groove 13.

[0028] In view of the fact that if a single saw tooth is subjected to a large instantaneous impact force during the process of dividing the band saw blade, the saw tooth may be damaged, specifically, the power assembly 3 comprises a first cylinder 30, a bevel sliding block 31 and a connecting sliding block 32, the bevel sliding block 31 is slidingly connected in the longitudinal groove 12, the connecting sliding block 32 is slidingly connected in the transverse groove 13, and the connecting sliding block 32 is in contact with the bevel of the bevel sliding block 31, the first cylinder 30 is fixedly connected to the side wall of the base plate 1, and the piston rod of the first cylinder 30 is fixedly connected to the bevel sliding block 31 through the side wall of the base plate 1, and the movement direction of the piston rod of the first cylinder 30 is consistent with the direction of the longitudinal groove 12; by the way that the connecting sliding block 32 slidingly connected in the transverse groove 13 is in contact with the bevel of the bevel sliding block 31 slidingly connected in the longitudinal groove 12, when the first cylinder 30 drives the bevel sliding block 31 to move along the longitudinal groove 12 through the piston rod, the bevel sliding block 31 will push the connecting sliding block 32 to move along the transverse groove 13 away from the longitudinal groove 12, that is, towards the direction of the band saw blade, thereby driving the movable plate 2 and the dividing tooth assembly 4 thereon to complete the division of the band saw blade, and the advantage of this way is that the saw tooth is stably stressed and is not easy to be damaged by a large instantaneous force.

[0029] In view of the fact that the way that the connecting sliding block 32 is pushed to move in the longitudinal groove 12 by the contact between the bevel of the bevel sliding block 31 and the connecting sliding block 32 has the following disadvantages: after the movable plate 2 is displaced along with the connecting sliding block 32 and divides the band saw blade, in the process of contraction of the piston rod of the first cylinder 30, the bevel of the bevel sliding block 31 is out of contact with the connecting sliding block 32, and thus cannot automatically return to the initial position, which means that the band saw blade cannot be continuously divided, and thus other auxiliary measures are needed to ensure the continuity of the division of the band saw blade, specifically, the movable plate 2 is provided with a matching elastic assembly 5, the elastic assembly 5 comprises a mounting plate 50, an extension tube 51 and a spring 52, the mounting plate 50 is fixedly connected to the side wall of the movable plate 2 away from the dividing tooth assembly 4, one end of the extension tube 51 is fixedly connected to a fixed part, the other end passes through the spring 52 and is fixedly connected to the mounting plate 50, and the two ends of the spring 52 are fixedly connected to the mounting plate 50 and the fixed part respectively; the elastic assembly 5 is used to assist the return of the movable plate 2, when the movable plate 2 is displaced, it will generate a pulling force on the spring 52, when the bevel sliding block 31 moves towards the first cylinder 30, the connecting sliding block 32 will return to the initial position under the action of the spring 52, and the use of the extension tube 51 can further ensure that the movable plate 2 will not shake.

[0030] Considering that the teeth need to be separated and the saw teeth need to be deviated to both sides, two groups of tooth separating assemblies 4 need to act on different teeth. Specifically, the two groups of first air cylinders 30 are provided with air cylinder PLC controllers. The air cylinder PLC controllers are connected with the reversing valves of the first air cylinders to control the extension and retraction states of the piston rods of the two groups of first air cylinders 30, and then control the two groups of tooth separating assemblies 4 to respectively contact the adjacent two saw teeth of the band saw blade and make the saw teeth deviate.

[0031] Considering that the tooth pitch of different specifications of band saw blades is different, different molds need to be replaced for pimple. In order to simplify the replacement process of the mold and reduce the workload of the operator, the mold plate is optimized. Specifically, the tooth separating assembly 4 includes a longitudinal plate 40, a first transverse plate 41, a second transverse plate 42 and a tooth separating plate 43. The longitudinal plate 40 is fixedly connected to the side wall of the movable plate 2 by a first fixing bolt 400. The first transverse plate 41 is fixedly connected with the longitudinal plate 40. The second transverse plate 42 is fixedly connected with the first transverse plate 41 by a second fixing bolt 420. The first transverse plate 41 and the second transverse plate 42 are provided with a tooth separating plate mounting groove 44 at the contact position. The tooth separating plate 43 is placed in the tooth separating plate mounting groove 44.

[0032] The longitudinal plate 40 can be fixed to the side wall of the movable plate 2 by the first fixing bolt 400. When different specifications of longitudinal plates 40 need to be replaced, it is also convenient to replace. The tooth separating plate mounting groove 44 is arranged at the contact position of the first transverse plate 41 and the second transverse plate 42, so that different specifications of tooth separating plates 43 can be installed. The first transverse plate 41 and the second transverse plate 42 are fastened by the second fixing bolt 420, and the tooth separating plate 43 is clamped and fixed by the mounting groove 44 at the contact position of the first transverse plate 41 and the second transverse plate 42.

[0033] Specifically, the base plate 1 is provided with an auxiliary clamping groove 11 in the same direction as the band saw blade. Considering that only the teeth of the band saw blade are extruded by the tooth separating plate 43 during actual tooth separation, in order to avoid the bending of the band saw blade itself, the auxiliary clamping groove 11 is arranged to clamp and hold the band saw blade.

[0034] Considering that the band saw blade is in a disc shape during transportation after forming, slight bending will occur without external interference, and if the band saw blade is bent during tooth separation, the tooth separation of the band saw blade will be affected. Specifically, the base plate 1 is provided with at least one set of auxiliary clamping assemblies 6 fixedly connected thereto, the auxiliary clamping assemblies 6 include two sets of L-shaped plates 60, two sets of rotating clamping rollers 61, two sets of connecting rods 62 and a second air cylinder 63, one end of the connecting rod 62 is fixedly connected with the L-shaped plate 60, the other end is bearing-connected with the rotating clamping roller 61, the second air cylinder 63 is fixedly connected to the side wall of the base plate 1, the two sets of L-shaped plates 60 are respectively located on the two sides of the auxiliary clamping groove 11, the L-shaped plate 60 away from the second air cylinder 63 is fixedly connected to the side wall of the base plate 1, and the L-shaped plate 60 close to the second air cylinder 63 is fixedly connected with the piston rod of the second air cylinder 63; the tooth separation of the band saw blade is assisted by the two sets of auxiliary clamping assemblies 6, the auxiliary clamping assemblies 6 are arranged at the two ends of the movable plate 2, the band saw blade is clamped by the two sets of rotating clamping rollers 61, and the clamping does not affect the normal tooth feeding of the band saw blade; and the second air cylinder 63 can adjust the distance between the two sets of rotating clamping rollers 61, so that the distance between the two sets of rotating clamping rollers 61 is adjusted according to different specifications of the band saw blade.

[0035] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
