[0002] The raw material for saw blade manufacturing is a steel strip that meets the required width. To make a saw blade, teeth need to be cut on the steel strip. Currently, the equipment used for tooth cutting is mainly stamping equipment and laser cutting equipment. Stamping equipment requires a mold, and different tooth shapes correspond to different stamping molds, which has a high cost problem. Laser cutting equipment can realize cutting processing of various tooth shapes by programming the displacement trajectory of the cutting head. Therefore, laser cutting processing equipment has gradually been widely used in the field of saw blade tooth cutting processing.

[0003] At present, due to the long length of the steel strip and the continuous saw teeth on the steel strip, a large number of saw blade production lines have appeared on the market to continuously cut the teeth of the steel strip; however, the existing production lines still have the following shortcomings when in use: 1. Due to the thin thickness of the steel strip, the temperature of the steel strip increases during laser cutting, and the steel strip is prone to warping and deformation in the cutting area, resulting in bending stress after the steel strip is cut, requiring subsequent correction treatment, and reducing production efficiency; 2. Smoke and dust are easily generated during laser cutting, which can easily cause environmental pollution and be detrimental to the health of the operator.

[0004] To this end, the utility model provides a saw blade production line. Utility Model Content

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] See also Figures 1 to 5The utility model provides a technical solution: a saw blade production line, including a bed 1, the top of the bed 1 is provided with a loading roller group 2, a clamping device 3, a gantry beam 4 and a discharge roller group 5 in sequence from left to right. When in use, the steel strip is placed on the top of the bed 1 and one side passes through the loading roller group 2, the clamping device 3, the gantry beam 4 and the discharge roller group 5. The clamping device 3 and the bed 1 are connected to slide back and forth. The function of the clamping device 3 is to clamp the steel strip and convey it in the downstream direction. The loading roller group 2 and the discharge roller group 5 play the role of supporting and guiding the steel strip, wherein the loading roller group 2 also has the function of flattening the steel strip, that is, the curled steel strip will be flattened when passing through the loading roller group 2. Therefore, when using this production line to process the steel strip, there is no need to flatten the steel strip separately, thereby improving the continuity of production.

[0026] The top of the gantry beam 4 is laterally slidably connected to a Z-axis cutting frame 6, and one side of the Z-axis cutting frame 6 is slidably connected to a serrated cutting head 7 located on the upstream side of the gantry beam 4. The lateral movement of the Z-axis cutting frame 6 and the up and down movement of the serrated cutting head 7 are coordinated with the translation of the steel belt to realize the tooth opening action, wherein the serrated cutting head 7 is provided with a laser cutter.

[0027] In this technical solution, the bed 1 is provided with an anti-warping roller group 8 located on the upstream and downstream sides of the serrated cutting head 7. The area where the serrated cutting head 7 is located is the laser tooth opening area. The function of the anti-warping roller group 8 is to roll and flatten the passing steel strip to avoid the problem of the steel strip teeth warping due to heat.

[0028] Specifically, a base 11 for supporting the anti-warping roller group 8 is fixedly provided on the top of the bed 1. The base 11 includes vertical plates located on both sides of the steel belt. The anti-warping roller group 8 includes an upper pressure roller 81, a lower roller 82, a positioning plate 83 and an anti-warping cylinder 84. Both sides of the base 11 are fixedly connected with the anti-warping cylinder 84. Specifically, the anti-warping cylinder 84 is fixedly installed on the outer side of the vertical plate, and the positioning plate 83 is fixedly provided above the base 11 and its bottom is fixedly connected to the output shaft of the anti-warping cylinder 84. The lower roller 82 is rotatably connected to the base 11. Specifically, the two ends of the lower roller 82 are rotatably connected to the opposite sides of the two vertical plates, and the upper pressure roller 81 is rotatably connected to the bottom of the positioning plate 83. After the anti-warping cylinder 84 is started, it can drive the positioning plate 83 to move up and down, and then drive the upper pressure roller 81 to squeeze the lower roller 82, thereby realizing the function of rolling the passing steel belt.

[0029] Furthermore, the clamping device 3 includes a slide 31 and a clamping cylinder group 32 arranged on the top of the slide 31. The slide 31 is slidably connected to the slide rail arranged on the top of the bed 1. A front pad 311 is fixedly arranged in the slide 31. The clamping cylinder group 32 is located above the front pad 311. A control cylinder and a pressure plate located at the output shaft end of the control cylinder are arranged on the clamping cylinder group 32. When the control cylinder is actuated, the pressure plate is used to press the steel belt against the front pad 311. At this time, the clamping device 3 can drive the steel belt to move when it moves.

[0030] Among them, a rear pad 111 is provided in the base 11 near the upstream end, and a clamping cylinder group 32 is provided on the top of the base 11 above the rear pad 111. When the rear pad 111 and the clamping cylinder group 32 clamp the steel belt, the clamping device 3 can be controlled to reset, which facilitates the reciprocating movement of the clamping device 3 and realizes the function of continuously clamping the steel belt downstream.

[0031] In this embodiment, the clamping device 3 includes a servo motor 33 and a rack 34. The servo motor 33 is fixedly arranged on one side of the slide 31 and its output shaft is fixedly connected to the transmission gear. The rack 34 is fixedly arranged on the top of the bed 1 and meshes with the transmission gear. The servo motor 33 provides driving force for the rotation of the transmission gear. After the servo motor 33 is started, it can accurately drive the slide 31 to move under the limit of the rack 34, and the slide 31 drives the clamped steel belt to move. The feeding drive mode of this clamping device 3 has high positioning accuracy and does not slip, which is better than the equipment that uses roller rolling to feed, and roller rolling feeding is prone to slip.

[0032] Furthermore, a centering adjuster 9 is provided on both the slide 31 and the base 11. There are two centering adjusters 9 on the base 11, one located on the upstream and downstream sides of the sawtooth cutting head 7. The function of the centering adjuster 9 is to prevent the steel strip from deflecting left and right during movement, thereby ensuring the accuracy of the steel strip's teeth. The centering adjuster 9 adopts a common structure in which a lead screw controls the lateral movement of the slider. In specific implementation, the slider can be slidably connected within the base 11 and the slide 31, and then two limit baffles are provided on one side of the slider. The steel strip passes through the two limit baffles, and then a lead screw is rotatably connected to each of the base 11 and the slide 31. The lead screw and the slider are screwed through and connected, thereby adjusting the steel strip to the center position by controlling the rotation of the lead screw.

[0033] In this embodiment, a collection box 101 is fixedly installed within the bed 1, below the sawtooth cutting head 7. A dust removal fan 102 is connected to one side of the collection box 101. The top of the collection box 101 is open, and waste generated by the sawtooth cutting of the steel strip falls into the collection box 101, which serves as a waste collection device. The dust removal fan 102 is used to remove the smoke and dust generated by cutting. When in use, the dust removal fan 102 is connected to an external bag dust removal system.

[0034] Furthermore, a material discharge inclined pipe 1011 is fixedly connected to the bottom of the collection box 101, and one end of the material discharge inclined pipe 1011 extends to one side of the bed 1. The bottom of the material discharge inclined pipe 1011 is tilted downward, and the function of the material discharge inclined pipe 1011 is to guide the waste in the collection box 101 outward to facilitate the transfer of waste.

[0035] In this embodiment, the specifications of the upper and lower material roller groups 2 and 5 are the same. The upper and lower material roller groups 2 include a bracket 21, a lower roller 22 and an upper roller 23. A row of lower rollers 22 are rotatably connected in the bracket 21. Two parallel supporting beams are provided on the bracket 21. The top of the bracket 21 and the position near the two ends are connected to the longitudinal beam 1 211 and the longitudinal beam 2 212 located on the side of the longitudinal beam 1 211 by sliding up and down. There is a longitudinal beam 1 211 and a longitudinal beam 2 212 corresponding to the top of each supporting beam. The longitudinal beam 212 is provided close to the bed 1. A row of upper rollers 23 are rotatably connected between the two longitudinal beams 212. There is at least one upper roller 23 rotatably connected between the two longitudinal beams 1 211. When in use, the steel strip passes through the space between the lower roller 22 and the upper roller 23. This arrangement facilitates the flattening of the curled steel strip, making the flattened steel strip smoother.

[0036] The bracket 21 is provided with a screw rod 213 for controlling the vertical sliding of the second longitudinal beam 212 and the first longitudinal beam 211. In practice, a limit beam can be fixedly installed above the bracket. The screw rod 213 and the limit beam penetrate and are rotatably connected. The first longitudinal beam 211 and the second longitudinal beam 212 are both screwed together with the adjacent screw rod 213. Rotating the screw rod 213 can control the vertical movement of the first longitudinal beam 211 and the second longitudinal beam 212, thereby controlling the gap between the lower roller 22 and the upper roller 23. This arrangement makes the steel strip more stable in and out and effectively prevents rebound and curling of the flattened steel strip.

[0037] Working principle: When in use, the steel strip is introduced from the upper feeding roller group 2 and passes through the clamping device 3, and then passes through the upper pressure roller 81 and the lower roller 82 on the anti-warping roller group 8. The anti-warping cylinder 84 is controlled to operate so that the upper pressure roller 81 and the lower roller 82 press the steel strip, and the Z-axis cutting frame 6 is controlled to move horizontally, driving the sawtooth cutting head 7 to be located above the tooth-cutting part of the steel strip. The sawtooth cutting head 7 is then controlled to descend so that the laser emitter at its bottom is close to the steel strip. The production line is then started, and the clamping device 3 conveys the steel strip downstream, and cooperates with the left and right translation of the Z-axis cutting frame 6 to continuously cut the steel strip. During this process, the dust removal fan 102 is started, and the dust removal fan 102 sucks away the smoke and dust generated in the tooth-cutting area, eliminating smoke and dust pollution. It should be noted that when the clamping device 3 in this production line reciprocates, it cooperates with the reciprocating movement of the clamping cylinder group 32 at each part to facilitate the continuous transmission of the steel strip downstream, thereby achieving continuous cutting of the steel strip and continuous and efficient production of saw blades.

[0038] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
