Description

Technical Field

[0001] The utility model relates to the technical field of band saw machine tool processing, in particular to a positioning mechanism for a band saw cutting station. Background Art

[0002] A metal band saw is a type of sawing equipment that uses a continuously rotating metal saw blade as a cutting tool. It is primarily used for cutting square and round materials, as well as various profiles, such as low-alloy steel, high-alloy steel, special alloy steel, and stainless steel. It can also be used to cut non-metallic materials. Because the saw blade creates a narrow kerf and high cutting efficiency, it consumes less energy and reduces material waste, making it a highly efficient cutting machine tool with significant energy and material savings.

[0003] When cutting a certain length of metal pipes, bars, or other steel sections in large quantities, workers first draw a marking line on the metal material to be cut, then align the cutting edge with the saw blade and cut. After cutting the previous section of metal material, they manually feed the material in the direction of the saw blade. Then, the workers use a measuring tool such as a tape measure or a steel ruler to draw another marking line on the metal material, align the saw blade with the saw blade, and start the saw machine so that the saw blade begins cutting along the marking line. The existing operation method has the following defects: when cutting a certain length of metal material in large quantities, workers need to repeatedly measure and draw marking lines on the metal material, which not only affects the cutting efficiency, but also the dimensional accuracy of manual measurement is subject to errors and poor repeatability, resulting in the cut metal material not meeting the requirements and causing waste of resources.

[0004] Therefore, it is necessary to develop a positioning mechanism for a band saw cutting station in view of the above defects. Utility Model Content

[0005] The purpose of the utility model is to provide a positioning mechanism for a band saw cutting station, which can flexibly position a metal material on a rear end support frame, avoids repeated line marking, and improves working efficiency.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0007] The utility model discloses a positioning mechanism for a band saw cutting station, which is arranged on a support frame at the rear end of a band saw machine, wherein the support frame comprises a roller bracket and a conveyor roller, and a plurality of the conveyor rollers are rotatably arranged at equal intervals on the top of the roller bracket, and the conveyor roller supports the metal material to be cut by the band saw, and comprises a light bar bracket, a guide light bar, a positioning flap and a locking assembly; the guide light bar is horizontally arranged along the length direction of the support frame and is supported by the light bar bracket at both ends; the root of the positioning flap is guided and slidably connected to the guide light bar by a guide sleeve, and the main body of the positioning flap is vertically arranged along the width direction of the support frame and is located directly above the conveyor roller; the locking assembly can position the other end of the positioning flap, and the positioning flap limits the distal end face of the metal material.

[0008] Furthermore, the locking assembly includes a long lead screw, a positioning nut and a lead screw bracket. The long lead screw is parallel to the guide light rod and is arranged on the other side of the support frame. The positioning nut is threadedly connected to the long lead screw through the middle threaded hole. The positioning nut can limit the bottom edge of the other end of the positioning flap.

[0009] Furthermore, a full-circle snap ring groove is centrally provided on the outer wall of the positioning screw sleeve, and the width of the snap ring groove is adapted to the thickness of the main plate of the positioning flap.

[0010] Furthermore, the top edge of the side wall of the snap ring groove is set to be chamfered.

[0011] Furthermore, a grease nipple is installed on the guide sleeve, and the inner end of the grease nipple mounting hole is connected to the spiral oil groove on the inner wall of the guide sleeve.

[0012] Furthermore, the light bar bracket is provided with a waist-shaped hole at the installation position of the guide light bar end, and the waist-shaped hole is vertically arranged in the length direction; the screw bracket is provided with a waist-shaped hole at the installation position of the long screw end, and the waist-shaped hole is vertically arranged in the length direction.

[0013] Furthermore, the bottoms of the four supporting legs of the roller bracket are respectively provided with adjustable supporting legs.

[0014] Compared with the prior art, the beneficial technical effects of the present invention are:

[0015] This practical band saw positioning mechanism for a cutting station utilizes a horizontally positioned guide bar along the length of the support frame, allowing the positioning flap to slide left and right along the guide bar, enabling adjustment of the guide bar's positioning position. The addition of a locking assembly locks the positioning flap in place on the guide bar, improving repeat positioning accuracy during mass cutting and preventing scrap. The positioning flap can be rotated circumferentially along the guide bar, allowing the entire support frame to be freed for single-piece cutting without using the positioning flap, without affecting the cutting of the individual pieces.

[0016] In addition, by threading the positioning screw sleeve onto the lead screw, the position of the positioning flap can be locked at any position along the length of the lead screw, with high positioning accuracy; by providing a snap ring groove on the outer wall of the positioning screw sleeve, the bottom edge of the other end of the positioning flap can be snapped and limited to achieve locking. By adding an oblique chamfer, the bottom edge of the positioning flap can be smoothly snapped into the snap ring groove to avoid hard collisions. By adding a grease nipple and a spiral oil groove for introducing lubricating grease, the wear between the guide sleeve and the guide light bar can be reduced, thereby increasing the service life. By setting the end mounting holes of the guide light bar and the lead screw as waist-shaped holes, the height positions of the guide light bar and the lead screw can be slightly adjusted to avoid interference between the bottom edge of the positioning flap and the top surface of the conveyor roller. By setting the adjustable legs, the support height of the roller bracket can also be adjusted to avoid bending of metal materials that need to be sawed. BRIEF DESCRIPTION OF THE DRAWINGS

Therefore, they cannot be understood as limitations on the present invention.

[0026] With reference to the accompanying drawings, Figure 1 This is a schematic diagram of the main structure of the positioning mechanism for the cutting station of the band saw of the utility model; Figure 2 This is a schematic diagram of the right side cross-sectional structure of the positioning mechanism for the cutting station of the band saw of the utility model; Figure 3 for Figure 2 Schematic diagram of the structure of the middle positioning flap in the open state; Figure 4 This is a schematic diagram of the cross-sectional structure of the positioning screw sleeve of the present utility model.

[0027] In one embodiment, Figures 1 to 4 As shown, the positioning mechanism for the band saw cutting station of the present invention is mounted on the support frame at the rear end of the band saw machine to limit the end faces of metal pipes, bars, and steel sections to be cut by the band saw. The support frame includes a roller bracket 1 and conveyor rollers 2. Multiple conveyor rollers 2 are rotatably mounted on top of the roller bracket 1 at equal intervals. The ends of the central shafts of the conveyor rollers 2 are connected to the mounting holes of the support side panels 101. The conveyor rollers 2 support the metal material to be cut by the band saw. The positioning mechanism for the band saw cutting station of the present invention includes a guide bar bracket 4, a guide bar 5, a positioning flap 6, and a locking assembly. The guide bar 5 is horizontally arranged along the length of the support frame, and its ends are supported by the guide bar bracket 4. The base of the positioning flap 6 is slidably connected to the guide bar 5 via a guide sleeve 601, that is, the guide sleeve 601 is sleeved onto the guide bar 5. The main body of the positioning flap 6 is vertically arranged along the width of the support frame, and the positioning flap 6 is located directly above the conveyor rollers 2. The locking assembly can position the other end of the positioning flap 6, and the positioning flap 6 limits the distal end surface of the metal material, and the distal end surface of the metal material abuts against the side wall of the positioning flap 6 facing the band saw.

[0028] By horizontally positioning the guide light bar 5 along the length of the support frame, and sliding the positioning flap 6 left and right along the guide light bar 5, the positioning position of the guide light bar 5 can be adjusted. By adding the locking assembly, the positioning flap 6 can be locked in position on the guide light bar 5, improving the accuracy of repeated positioning during large-scale cutting and avoiding waste. By providing the positioning flap 6 to be able to rotate circumferentially along the guide light bar 5, the entire support frame can be released when cutting a single product without using the positioning flap 6, without affecting the cutting of the single product.

[0029] In a specific embodiment of the present invention, Figures 1 to 4 As shown, the locking assembly includes a long screw 7, a positioning screw sleeve 8 and a screw support 9. The long screw 7 is parallel to the guide light bar 5 and is arranged on the other side of the support frame. The positioning screw sleeve 8 is threadedly connected to the long screw 7 through the threaded hole 802 in the middle. The positioning screw sleeve 8 can limit the bottom edge of the other end of the positioning flap 6.

[0030] Specifically, if Figure 4 As shown, a full-circle snap ring groove 801 is centrally defined on the outer wall of the positioning screw sleeve 8. The width of the snap ring groove 801 is adapted to the thickness of the main plate of the positioning flap 6. Correspondingly, a snap interface 602 is defined on the bottom surface of the other end of the positioning flap 6. The snap interface 602 is a circular arc groove that mates with the bottom surface of the snap ring groove 801.

[0031] By threading the positioning screw sleeve 8 onto the lead screw 7, the position of the positioning flap 6 can be locked at any position along the length direction of the lead screw 7 with high positioning accuracy; by opening a snap ring groove 801 on the outer wall of the positioning screw sleeve 8, the bottom edge of the other end of the positioning flap 6 can be snapped and limited to achieve locking.

[0032] Obviously, a snap-fitting convex ring can also be provided on the positioning nut 8, and a corresponding locating groove can be provided on the bottom surface of the other end of the positioning flap 6. The convex ring is inserted into the locating groove to lock the positioning flap 6. Such simple replacement forms fall within the scope of protection of the present invention.

[0033] Specifically, if Figure 4 As shown, the top edge of the side wall of the snap ring groove 801 is set as an oblique chamfer 803.

[0034] By adding the oblique chamfer 803 , the bottom edge of the positioning flap 6 can be smoothly inserted into the snap ring groove 801 to avoid hard collision.

[0035] In order to improve the loosening of the positioning screw sleeve 8, a large lock nut can be added to the long lead screw 7. The large lock nut is locked on the end face of the positioning screw sleeve 8 to prevent the positioning screw sleeve 8 from loosening.

[0036] Specifically, a grease nipple is installed on the guide sleeve 601 , and the inner end of the grease nipple installation hole is connected to the spiral oil groove on the inner wall of the guide sleeve 601 .

[0037] By adding a grease nipple and a spiral oil groove for introducing lubricating grease, the wear between the guide sleeve 601 and the guide light bar 5 can be reduced, thereby increasing the service life.

[0038] In a specific embodiment of the present invention, Figures 1 to 3 As shown, the optical bar bracket 4 is provided with a waist-shaped hole at the end mounting position of the guide optical bar 5, and the waist-shaped hole is vertically arranged in the length direction. The lead screw bracket 9 is provided with a waist-shaped hole at the end mounting position of the long lead screw 7, and the waist-shaped hole is vertically arranged in the length direction.

[0039] Specifically, the bottoms of the four supporting legs of the roller bracket 1 are respectively provided with adjustable supporting legs 3. Here, the adjustable supporting legs 3 use screw rods as adjustable supporting rods.

[0040] By configuring the end mounting holes of the guide light bar 5 and the long lead screw 7 as waist-shaped holes, the height positions of the guide light bar 5 and the long lead screw 7 can be slightly adjusted, thus preventing interference between the bottom edge of the positioning flap 6 and the top surface of the conveyor roller 2. The provision of the adjustable legs 3 also allows the support height of the roller bracket 1 to be adjusted, thus preventing bending of the metal material to be sawed.

[0041] The positioning mechanism for the band saw cutting station in this embodiment operates as follows: First, based on the desired length of metal material to be cut, the distance between the outer end face of the band saw and the positioning flap 6 is measured using a ruler. After initially determining the positioning position, the positioning screw 8 is rotated to the corresponding position on the lead screw 7. The positioning flap 6 is then pushed and pulled, and the guide sleeve 601 slides along the guide light bar 5 to the corresponding position of the positioning screw 8. The operator then turns the distal end of the positioning flap 6, causing it to flip upward around the guide light bar 5 and allowing the locking interface 602 to fall into the locking ring groove 801. The operator pushes the metal material through the saw cut and rolls it backward on the conveyor roller 2 until the distal end of the metal material abuts the positioning flap 6 facing the side wall of the band saw. Using a ruler, the operator re-measures the metal material to ensure the cut length meets the required accuracy. If not, the locking interface 602 of the positioning flap 6 is lifted, the positioning screw 8 is precisely adjusted, the positioning flap 6 is replaced, locked, and the measurement is repeated until the required accuracy is met. Use a wrench to lock the large lock nut onto the end face of the positioning screw sleeve 8 to prevent it from loosening. Re-align the distal end face of the metal material with the side wall of the positioning flap 6, and start the band saw to cut the metal material to the desired length. After cutting, remove the cut material and re-measure the length. If there are no problems, proceed with batch sawing.

[0042] In summary, by horizontally arranging the guide light bar 5 along the length direction of the support frame, the positioning flap 6 slides left and right along the guide light bar 5, and the positioning position of the guide light bar 5 can be adjusted; by adding the locking assembly, the position of the positioning flap 6 on the guide light bar 5 can be locked, thereby improving the accuracy of repeated positioning during large-scale cutting and avoiding the occurrence of waste products. By setting the positioning flap 6 to be able to flip circumferentially along the guide light bar 5, the entire support frame can be freed in the case of single-item cutting without using the positioning flap 6 for positioning, without affecting the cutting of the single item. In addition, by threading the positioning screw sleeve 8 on the lead screw 7, the position of the positioning flap 6 can be locked at any position along the length direction of the lead screw 7, with high positioning accuracy; by providing the snap ring groove 801 on the outer wall of the positioning screw sleeve 8, the bottom edge of the other end of the positioning flap 6 can be snapped and limited to achieve locking. By adding the chamfer 803, the bottom edge of the positioning flap 6 can be smoothly snapped into the snap ring groove 801, avoiding hard collisions. The addition of a grease nipple and spiral oil groove for lubricating grease reduces wear between the guide sleeve 601 and the guide light bar 5, extending its service life. By designating the end mounting holes of the guide light bar 5 and the lead screw 7 as waist-shaped holes, their heights can be fine-tuned, preventing interference between the bottom edge of the positioning flap 6 and the top surface of the conveyor roller 2. The provision of adjustable legs 3 also allows for adjustment of the support height of the roller bracket 1, preventing bending of the metal material being sawed.
