Description

Technical Field

[0001] This invention relates to the field of band saw blade processing technology, and in particular to a rolling mechanism, rolling equipment and a band saw blade rolling method. Background Technology

[0002] Bimetal band saw blades are made by laser welding the tooth material (M42, B2000, M51) and the backing material (high-quality spring steel X32, B318, etc.) together, followed by heat treatment and other processing steps. Bimetal band saw blades are widely used in metal and non-metal cutting applications. Due to changes in market and customer demands, customers are increasingly requiring higher sawing efficiency and longer cutting life. Bimetal band saw blade manufacturers are continuously upgrading the tooth material, from ordinary M42, powder M42 (B2000), to M51, improving tooth performance and significantly enhancing tooth wear resistance and cutting life.

[0003] However, breakthroughs in backing material selection have been lacking, leading to processing quality issues such as skewed cuts and band breakage during overcutting of band saw blades due to the mismatch between backing material performance and tooth material performance. Analysis reveals the following main reasons for skewed cuts or band breakage during band sawing: Excessive sawing efficiency causes continuous wear on the tooth tips, reducing their sharpness and increasing cutting resistance. This resistance is also transmitted to the backing plate. Insufficient rigidity of the backing material results in uneven stress distribution on both sides during cutting, causing vibration and further exacerbating tooth tip chipping, thus increasing cutting resistance. If the tooth tips succumb to the resistance before the backing material, abnormal wear or skewed cuts will occur, potentially leading to tooth breakage. Conversely, if the backing material succumbs to the resistance before the teeth, band breakage will result.

[0004] In addition, due to frequent handling and loading / unloading during the production process, bimetal band saw blades are prone to damage at the bottom. Even small defects at the bottom of the blade can cause cracks during sawing. As the usage time increases, the cracks continue to expand until the entire band breaks.

[0005] To address the aforementioned technical challenges, the material properties of the backing material can be improved, or the band saw blade processing technology can be altered. However, developing a backing material with superior performance presents significant difficulties, high costs, and long development cycles. Given the lack of effective breakthroughs in backing material materials, improving backing material performance is crucial. Furthermore, the performance of bimetallic band saw blade backing materials is closely related to heat treatment and subsequent sandblasting processes. However, heat treatment typically employs oil quenching, and sandblasting utilizes shot blasting or dry blasting—both relatively mature processes, making significant breakthroughs difficult. Therefore, improving these two aspects of the process to alter the backing material's performance is also highly improbable.

[0006] To address processing quality issues such as skewed cuts and band breakage during band saw blade cutting, it is crucial to select appropriate processing methods that are easy to implement. Summary of the Invention

The second spindle is fixed to the second mounting base via a second end cover.

[0012] Preferably, the first roller pressing device is provided with a T-shaped nut, and the first driving mechanism is provided with a T-shaped screw connected to the T-shaped nut.

[0013] The present invention also provides a roller pressing device, including a base, a support seat disposed on the base, and a pressing mechanism as described above. The base is disposed on the base, and the support seat and the pressing mechanism are disposed at both ends of the roller pressing mechanism in a third direction. The support seat is provided with a support plate, the upper surface of the support plate is flush with the upper surface of the second roller, and the pressing mechanism and the support plate are subjected to a damping force.

[0014] Preferably, each of the support seats is provided with a first adjustment mechanism for adjusting the position of the support plate and the roller pressing mechanism in the second direction; a second adjustment mechanism is provided on the support seat near the front side of the rotation direction of the first roller and the second roller, the second adjustment mechanism being used to adjust the position of the support plate in the first direction.

The rolling force applied to the band saw blade by the rolling mechanism includes the compressive stress of the relative rotation of the first roller and the second roller and the pressing force of the first roller moving downward. 3) The band saw blade after roll pressing is output to the roll pressing mechanism through the damping force applied by the clamping mechanism and the support plate; thus completing the band saw blade roll.

[0022] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other. For ease of description, the terms "upper," "lower," "left," and "right" used below only indicate that they correspond to the upper, lower, left, and right directions in the accompanying drawings and do not limit the structure.

[0023] like Figure 1 As shown, the roller pressing equipment provided in this embodiment includes a roller pressing mechanism 1, a base 2, a support 3, a first adjusting mechanism 4, a second adjusting mechanism 5, a limiting mechanism 6, a pressing mechanism 7, and a polishing mechanism 8.

[0024] like Figure 2 As shown, the rolling mechanism 1 includes a first rolling device 11, a second rolling device 12, a base 13, a first driving mechanism 14, and a second driving mechanism 15. The first rolling device 11 and the second rolling device 12 are arranged vertically opposite each other in the base 13, and are positioned opposite each other in a first direction Z. The first rolling device 11 has at least three first rollers 113, and each of the second rolling devices 12 has at least three second rollers 123. The at least three first rollers 113 and the at least three second rollers 123 are arranged in a second direction Y, and rotate relative to each other to form at least three compressive stresses, which extend in a third direction X. The first driving mechanism 14 drives the first rolling device 11 to move closer to or away from the first rolling device 11 in the first direction Z. The second driving mechanism 15 drives the second rolling device 12 to rotate to form the compressive stresses.

[0025] Specifically, such as Figure 3As shown, the first roller pressing device 11 further includes a first mandrel 111, a first mounting base 112, a first end cap 114, a locking nut 115, a T-nut 116, and a bearing 117. The second roller pressing device 12 further includes a second mandrel 121, a second mounting base 122, a second end cap 124, a coupling 125, and the same locking nut 115 and bearing 117 as in the first roller pressing device 11.

[0026] The second mounting base 122 is connected to the bottom of the base 13. The second spindle 121 is rotatably mounted in the second mounting base 122 via a bearing 117, with one end of the second spindle 121 extending to the outside of one end of the second mounting base 122 for mounting the second roller 123, and the other end of the second spindle 121 extending to the outside of the other end of the second mounting base 122 and connected to the second drive mechanism 15 via a coupling 125. The second spindle 121 is fixed to the second mounting base 122 via a second end cap 124 and screws. The second drive mechanism 15 is a drive motor. Bearings 117 are fitted at both ends of the second spindle 121, and the bearing 117 near the second roller 123 is fixed by a locking nut 115 at the end of the second spindle 121. The second end cap 124 is used to define the outer ring of the bearing 117. A pressure cap 118 is fitted on the second spindle 121 for abutting against the inner ring of the bearing 117. The second spindle 121 is also fitted with a locking nut 115 for defining the position of the pressure cap 118.

[0027] The first drive mechanism 14 includes a third mounting base 141, a hydraulic cylinder 142, and a T-shaped screw 143. The third mounting base 141 is inserted into the top of the base 13 in a first direction Z. The hydraulic cylinder 142 is mounted in the third mounting base 141, and the T-shaped screw 143 is provided at the end of the telescopic rod of the hydraulic cylinder 142.

[0028] The first mounting base 112 is slidably fitted into the base 13, and is located above the second mounting base 122. The first spindle 111 is rotatably mounted in the first mounting base 112 via bearings 117, with one end of the first spindle 111 extending to the outside of one end of the first mounting base 112 for mounting the first roller 113, and the other end of the first spindle 111 extending to the outside of the other end of the first mounting base 112 and fixed to the first mounting base 112 via a first end cap 114. Bearings 117 are fitted at both ends of the first spindle 111, and the bearing 117 near the first roller 113 is fixed by a locking nut 115 at the end of the first spindle 111. The first end cap 114 defines the outer ring of the bearing 117, and a pressure cap 118 is fitted on the first spindle 111 for abutting against the inner ring of the bearing 117. A locking nut 115 is also fitted on the first spindle 111 to define the position of the pressure cap 118. The first mounting base 112 is provided with a T-nut 116, and the T-screw 143 is connected to the T-nut 116 to better achieve the locking function of the connection and better transmission.

[0029] like Figure 1 , Figure 4 As shown, the roller pressing mechanism 1 is located at the upper end of the base 2, and the band saw blade 9 passes between the first roller pressing device 11 and the second roller pressing device 12 to form an inlet 16 and an outlet 17. A support seat 3 is also provided on the base 2, located on the inlet 16 side and the outlet 17 side of the roller pressing mechanism 1, to provide motion resistance for the band saw blade 9 when entering and exiting the roller pressing mechanism 1, and to ensure that the band saw blade 9 enters and exits along the tangential direction of the second roller 123.

[0030] like Figure 4 , Figure 5 As shown, the support base 3 includes a support plate 31 and a second adjusting rod 32. The upper surface of the support plate is flush with the upper surface of the second roller 123. The clamping mechanism 7 is disposed on the support base 3, and the clamping mechanism 7 and the support plate 31 form a damping force extending in the third direction X. The band saw blade 9 is fed from the feeding tray and enters through the inlet 16. After completing the roller pressing, it is output from the outlet 17 and returns to the receiving tray for winding. During this process, the band saw blade 9 has a traveling speed, which cannot be too fast during roller pressing. Therefore, in order to limit the speed, the clamping mechanism 7 is set to generate resistance. In addition, the clamping structure between the clamping mechanism 7 and the support plate 31 ensures that the band saw blade 9 enters the roller pressing mechanism 1 straight and stably. The clamping mechanism 7 includes a cylinder 71 and a pressure roller 72 disposed at the end of the telescopic rod of the cylinder 71. By extending and retracting the cylinder 71, the position of the pressure roller 72 is adjusted so that the pressure roller 72 contacts the band saw blade 9. Figure 5 As shown, the bottom of the support plate 31 is provided with a second adjusting rod 32 extending in the first direction Z.

[0031] like Figure 1 As shown, each of the support seats 3 is provided with a first adjustment mechanism 4 for adjusting the position of the support plate 31 and the roller pressing mechanism 1 in the second direction Y. A second adjustment mechanism 5 is provided on the support seat 3 near the front side (and the inlet 16 side) of the rotation direction of the first roller 113 and the second roller 123. The second adjustment mechanism 5 is used to adjust the position of the support plate 31 in the first direction Z.

[0032] The first adjustment mechanism 4 includes a first mounting plate 41, a first adjusting rod 42, and a linear bearing 43. One end of the first mounting plate 41 is connected to the support base 3, and the other end is provided with a linear bearing 43 for the first adjusting rod 42 to pass through. The bottom of the second adjusting rod 32 is inserted into the first adjusting rod 42. One end of the first adjusting rod 42 on both ends of the first adjustment mechanism 4 is connected by an adjusting handle 44, and the other end of the first adjusting rod 42 is connected to the base 13.

[0033] Pushing or pulling the adjustment handle 44 causes the first adjustment rod 42 to extend or retract, thereby adjusting the position of the support 3 and the base 13 in the second direction Y through the second adjustment rod 32.

[0034] like Figure 5 As shown, the limiting mechanism 6 includes a third mounting plate 61 and a limiting screw 62. One end of the third mounting plate 61 is connected to the bottom of the support base 3, and the other end is through which the first adjusting rod 42 passes. The limiting screw 62 is threaded onto the side wall of the third mounting plate 61, and the end of the limiting screw 62 contacts the first adjusting rod 42. The limiting mechanism 6 limits the position of the first adjusting rod 42.

[0035] The second adjustment mechanism 5 includes a second mounting plate 51 and an adjusting screw 52. The second mounting plate 51 is connected to the support base 3 below the support plate 31. The adjusting screw 52 is threadedly connected to the second mounting plate 51 in the first direction Z, and the end of the adjusting screw 52 is connected to the bottom of the support plate 31. The height of the support plate 31 is adjusted by the second adjustment mechanism 5. In addition, to facilitate the adjustment of the height of the support plate 31, a linear guide rail is provided at the bottom of the support plate 31, and the linear guide rail is connected to the support base 3. During the use of the roller, the roller will wear down. With the increase of the number of grinding cycles, the outer diameter of the roller becomes smaller, causing the band saw blade 9 to be unable to effectively fit with the support plate 31. To address this, the support plate 31 is adjusted upward by the second adjustment mechanism 5 so that it is fully fitted with the band saw blade 9, and together with the clamping mechanism 7, it applies force to the band saw blade 9.

[0036] In addition, depending on the shape of the tortoise shell of the band saw blade 9 ("M", "W", or "arc"), the second adjusting mechanism 5 can adjust the center position of the support plate 3 relative to the first roller 113 and the second roller 123 (towards or downwards) to achieve different tortoise shell rolling effects.

[0037] like Figure 1 , Figure 6 The polishing mechanism 8 is located beside the roller pressing mechanism 1. The polishing mechanism 8 is located behind the first roller 113 and the second roller 123 in the rotation direction (and on the outlet 17 side). The polishing mechanism 8 is provided with a grinding wheel 81 that rotates in the first direction Z.

[0038] like Figure 1 As shown, the support base 3 is also provided with a limiting bearing 33, which is located on the outlet 17 side and is always in contact with the bottom of the band saw blade 9.

[0039] like Figure 1 As shown, the present invention also provides a band saw blade rolling method, which uses the above-mentioned rolling equipment and includes: Step S1, divide the width of the band saw blade 9 into three rolling zones 91 (e.g., Figure 7 As shown, three first rollers 113 and second rollers 123 are installed corresponding to the positions of the three rolling areas. The three rolling areas correspond to the position of the band saw blade 9 near the tooth groove, the middle position of the band saw blade 9, and the position of the band saw blade 9 near the bottom. By increasing the compressive stress of the band saw blade 9 at these three positions by means of rolling, the rigidity of the backing material of the band saw blade 9 is enhanced.

[0040] Step S2: Adjust the positions of the support base 3 and the first roller 113 and the second roller 123. Since the bottom of the band saw blade 9 is always in contact with the limiting bearing 33, a positioning reference is formed. Then, the first adjusting mechanism 4 adjusts the positions of the first roller 113, the second roller 123, and the support plate 31 relative to the reference in the second direction Y, so that they are located in the corresponding rolling area 91. After the position is adjusted, it is locked by the limiting mechanism 6.

[0041] Step S3: Start the clamping mechanism 7 to clamp the band saw blade 9, ensuring that the band saw blade 9 does not deviate during the rolling process.

[0042] In step S4, the band saw blade 9 enters the rollers of the rolling mechanism 1 through the damping force applied by the clamping mechanism 7 and the support plate 31. Under the action of the hydraulic cylinder 142, the first rolling device 11 is driven to move downward; at the same time, the second driving mechanism 15 drives the second rolling device 12 to rotate. At this time, under the action of the first roller 113 and the second roller 123, the hydraulic pressure of the hydraulic cylinder 142 is transmitted to the band saw blade 9, thereby producing a slight deformation on the back of the band saw blade 9, thereby further enhancing the compressive stress. That is, the rolling pressure applied to the band saw blade 9 by the rolling mechanism 1 includes the compressive stress of the relative rotation of the first roller 113 and the second roller 123 and the displacement pressure of the first roller 113 moving downward.

[0043] In step S5, the band saw blade 9, after being rolled, is output to the rolling mechanism 1 through the damping force applied by the clamping mechanism 7 and the support plate 31. The band saw blade 9 is rolled.

[0044] Three or more grooves (such as) are formed on the band saw blade 9 of the final roll. Figure 7 (as shown), and the rolling process parameters can be flexibly customized according to the application scenario of the band saw blade.

[0045] Step S6: The band saw blade 9 enters the polishing mechanism 8, where the bottom of the band saw blade 9 is polished by the grinding wheel 81 to remove damage caused to the band saw blade 9 during the production process (such as...). Figure 8 As shown), it is polished using a grinding wheel 81 to form a shape like... Figure 9 The surface shown reduces damage to the bottom of the saw blade and extends its service life.

[0046] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
