Description

Technical Field

[0001] This utility model relates to the field of metal circular saw technology, and in particular to a double-headed metal circular saw. Background Technology

[0002] The production of RVs involves a large amount of metal cutting, in which a double-headed metal circular saw plays a crucial role. It can cut metal materials from both ends simultaneously, significantly improving cutting efficiency and reducing production time. Its precise cutting function ensures the dimensional accuracy of metal components, making the connections between various RV structures tighter and more stable. However, existing double-headed metal circular saws have some shortcomings in long-term use. When the saw blade rotates at high speed to cut metal materials, it generates a large amount of heat, which not only accelerates saw blade wear and shortens its lifespan but may also affect cutting accuracy and quality. Furthermore, existing equipment is not adept at handling metal debris during the cutting process; metal debris easily accumulates on the worktable, affecting operational convenience and potentially posing a safety hazard to operators. Therefore, a new double-headed metal circular saw is needed. Chinese patent provides a double-headed metal circular saw, publication number CN221087442U, which includes a workbench and a cutting assembly disposed on the top of the workbench. The cutting assembly includes a cutting part and a clamping part. The cutting part is located on the top of the workbench, and a connecting part is provided on the outer wall of the cutting part. The clamping part is located on the top of the workbench, and a fixing part is provided inside the clamping part.

[0003] The aforementioned double-headed metal circular saw can change the No. 1 clamping plate and the No. 2 clamping plate according to whether the workpiece is metal pipe or metal sheet, thereby increasing the processing range of the double-headed circular saw. However, when using the double-headed metal circular saw, the distance between the two circular saws is not flexible and convenient to adjust, and it requires the use of additional tools and complicated operating procedures. This not only increases the difficulty of the operator's work, but also consumes a lot of time and energy. Utility Model Content

[0004] The main purpose of this utility model is to provide a double-headed metal circular saw that can effectively solve the problem in the background art where the adjustment of the distance between the two circular saws is not flexible and convenient enough, and requires additional tools and complicated operating procedures to complete. This not only increases the difficulty of the operator's work, but also consumes a lot of time and energy.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A double-headed metal circular saw includes a sliding frame. Support plates are fixedly installed on the left and right outer walls of the sliding frame. Two sliding plates are slidably connected to the outer wall of the sliding frame. A circular saw is fixedly installed on the top of each of the two sliding plates. A fixing plate is fixedly installed on the outer wall of the sliding frame. A first screw is rotatably connected to the outer wall of the fixing plate. A handwheel is fixedly installed at one end of the first screw. A gear is fixedly installed near the top of the outer wall of the first screw.

[0006] As a further embodiment of this utility model, the gear has racks on both the front and rear outer walls, and the outer walls of the racks are meshed with the gear. Connecting blocks are fixedly installed at the distal ends of the two racks, and one side of the outer wall of the sliding plate of the connecting block is fixedly connected.

[0007] As a further embodiment of this utility model, the outer walls of both racks are provided with limiting frames, the outer walls of the two racks are slidably connected to the limiting frames, and the two limiting frames are fixedly connected to the fixing plate.

[0008] As a further embodiment of this utility model, a connecting strip is fixedly installed at the bottom of each of the two sliding plates, a movable plate is slidably connected to the outer wall of each of the two connecting strips, and a collection box is fixedly installed on one side of the outer wall of each of the two movable plates.

[0009] As a further embodiment of this utility model, a first bevel gear is fixedly installed on the bottom of the outer wall of the first screw, and a second bevel gear is provided on the outer walls of both the left and right sides of the first bevel gear, and the second bevel gear is meshed with the first bevel gear.

[0010] As a further embodiment of this utility model, a second screw is fixedly installed on the outer wall of each of the two second bevel gears, and the distal ends of the two second screws are rotatably connected to the support plate.

[0011] As a further embodiment of this utility model, the outer walls of the two second screws are provided with connecting plates, the outer walls of the two connecting plates are threadedly connected to the second screws, and the connecting plates are fixedly connected to the bottom of the sliding plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1) This double-head metal circular saw can drive the first screw to rotate by turning the handwheel. The rotation of the first screw can drive the gear to rotate. Through the meshing connection between the outer wall of the rack and the gear, the rotation of the gear can drive the rack to move. The two racks slide in opposite directions along the limit frame and push the sliding plate to slide on the sliding frame. This can change the distance between the circular saws on the sliding plate. When it is necessary to increase the distance between the two saw heads, the handwheel is rotated in the forward direction, which drives the sliding plate to separate. When it is necessary to decrease the distance between the two saw heads, the handwheel is rotated in the reverse direction, and the sliding plate is brought together, which is convenient for cutting metal materials of different specifications.

[0013] 2) In this double-headed metal circular saw, when the first screw rotates, the first bevel gear fixed to its outer wall near the bottom also rotates. Since the second bevel gears on both sides mesh with the first bevel gear, the rotation of the first bevel gear will drive the second bevel gear to rotate synchronously. As the second bevel gear rotates, the second screw fixedly connected to it also begins to rotate. Because the connecting plate and the second screw are threadedly connected, the rotation of the second screw will cause the connecting plate to move along the direction of the second screw, thus restricting the sliding plate and preventing the sliding plate from shifting or wobbling. This makes the circular saw more stable and reliable during the adjustment of the spacing. Attached Figure Description

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] Example 1 Combination Figures 1-4A double-headed metal circular saw includes a sliding frame 1, with support plates 2 fixedly installed on the left and right outer walls of the sliding frame 1. Two sliding plates 3 are slidably connected to the outer wall of the sliding frame 1, and a circular saw 4 is fixedly installed on the top of the two sliding plates 3.

[0018] See Figure 1 and Figure 2 Furthermore, a fixing plate 5 is fixedly installed on the outer wall of the sliding frame 1. A first screw 6 is rotatably connected to the outer wall of the fixing plate 5. A handwheel 7 is fixedly installed at one end of the first screw 6. A gear 8 is fixedly installed near the top of the outer wall of the first screw 6. A rack 9 is provided on both the front and rear outer walls of the gear 8, and the outer walls of the rack 9 are meshed with the gear 8. A connecting block 10 is fixedly installed at the distal ends of the two racks 9, and the outer walls of the connecting blocks 10 are fixedly connected to one side of the outer wall of the sliding plate 3. A limiting frame 11 is provided on the outer walls of the two racks 9, and the outer walls of the two racks 9 are slidably connected to the limiting frame 11. The two limiting frames 11 are fixedly connected to the fixing plate 5. A connecting strip 12 is fixedly installed at the bottom of the two sliding plates 3. A movable plate 13 is slidably connected to the outer walls of the two connecting strips 12. A collection box 14 is fixedly installed on one side of the outer wall of the two movable plates 13.

[0019] Specifically, the sliding frame 1 can fix the support plate 2, and the support plate 2 can support the sliding frame 1. The sliding plate 3 can slide along the outer wall of the sliding frame 1, and the circular saw 4 can be fixed by the sliding plate 3. The sliding frame 1 can fix the fixed plate 5. The first screw 6 can rotate along the outer wall of the fixed plate 5, and the first screw 6 can fix the handwheel 7. The first screw 6 can fix the gear 8. The outer wall of the rack 9 is meshed with the gear 8. When the gear 8 rotates, it can drive the rack 9 to move. The rack 9 can fix the connecting block 10, and the outer wall of the connecting block 10 is fixedly connected to one side of the outer wall of the sliding plate 3. The rack 9 can slide along the limiting frame 11, and the fixed plate 5 can fix the limiting frame 11. The sliding plate 3 can fix the connecting strip 12, and the movable plate 13 can slide along the outer wall of the connecting strip 12. The movable plate 13 can fix the collecting box 14, and the collecting box 14 can collect debris.

[0020] Example 2 See Figure 3 and Figure 4Furthermore, based on Embodiment 1, a first bevel gear 15 is fixedly installed on the bottom of the outer wall of the first screw 6. Second bevel gears 16 are provided on the left and right outer walls of the first bevel gear 15, and the second bevel gears 16 mesh with the first bevel gear 15. Second screws 17 are fixedly installed on the outer walls of both second bevel gears 16. The distal ends of the two second screws 17 are rotatably connected to the support plate 2. Connecting plates 18 are provided on the outer walls of both second screws 17. The outer walls of both connecting plates 18 are threadedly connected to the second screws 17, and the connecting plates 18 are fixedly connected to the bottom of the sliding plate 3.

[0021] Specifically, the first screw 6 can fix the first bevel gear 15. The second bevel gear 16 meshes with the first bevel gear 15. When the first bevel gear 15 rotates, it can drive the second bevel gear 16 to rotate, which in turn can drive the second screw 17 to rotate. One end of the second screw 17 can rotate along the support plate 2. The outer wall of the connecting plate 18 is threadedly connected to the second screw 17. When the second screw 17 rotates, it can drive the connecting plate 18 to move.

[0022] In actual operation, the operator first drives the first screw 6 to rotate by turning the handwheel 7. After the first screw 6 rotates, it drives the gear 9 to rotate. Through the meshing connection between the outer wall of the rack 9 and the gear 8, the rotation of the gear 8 drives the rack 9 to move. The two racks 9 slide in opposite directions along the limit frame 11 and push the sliding plate 3 to slide on the sliding frame 1. This changes the spacing of the circular saw 4 on the sliding plate 3. When it is necessary to increase the distance between the two saw heads, the handwheel 7 rotates in the forward direction, which drives the sliding plate 3 to separate. When it is necessary to decrease the distance between the two saw heads, the handwheel 7 rotates in the reverse direction, and the sliding plate 3 moves closer together, which is convenient for cutting metal materials of different specifications. When the first screw 6 rotates, the first bevel gear 15 fixed to the bottom of its outer wall also rotates. Since the second bevel gears 16 on both sides mesh with the first bevel gear 15, the rotation of the first bevel gear 15 will drive the second bevel gear 16 to rotate synchronously. As the second bevel gear 16 rotates, the second screw 17 fixedly connected to it also begins to rotate. Because the connecting plate 18 and the second screw 17 are threadedly connected, the rotation of the second screw 17 will cause the connecting plate 18 to move along the direction of the second screw 17, so that the sliding plate 3 can be restricted, avoiding the sliding plate 3 from deviating or shaking. This makes the circular saw 4 more stable and reliable in the process of adjusting the spacing. By effectively restricting the sliding plate 3, the operator can more accurately control the spacing between the two circular saws 4, thereby improving the accuracy of cutting metal materials of different specifications, enhancing the durability of the entire equipment, reducing the wear and damage of parts that may be caused by abnormal movement of the sliding plate 3, and greatly extending the service life of the double-headed metal circular saw.
