Description

Technical Field

[0001] This utility model relates to the technical field of band saw feeding, and specifically to a band saw feeding device. Background Technology

[0002] A band saw is a machine tool used for sawing various metal materials. It is classified by structure into horizontal and vertical types; and by function into semi-automatic, fully automatic, and CNC types. Horizontal band saws can be further divided into double-column and scissor types. The main components include: base, bed, column, saw beam and transmission mechanism, saw blade guide device, workpiece clamping device, saw blade tensioning device, feeding device, hydraulic transmission system, electrical control system, and lubrication and cooling system.

[0003] Currently, most feeding devices used in band saws employ roller drive mechanisms to achieve the feeding function. In order to ensure the stability of the material during sawing, existing feeding devices are also equipped with clamping devices to ensure the stability of the material during sawing and feeding.

[0004] In the bar sawing process, to improve sawing efficiency, multiple bars are often sawed simultaneously. However, due to the limitation of saw blade length, the number of bars that can be placed on the same layer is limited. Under the premise of limited placement length, in order to increase the number of cuts, the bars need to be stacked. Currently, the clamping devices on the feeding device use two vertical clamps to clamp the material. These clamps can play a good clamping role for square materials or bundled steel bars, but for stacked bars, they cannot achieve the purpose of clamping the upper bar, resulting in the lack of clamping for the stacked material, which easily leads to processing errors during sawing. Utility Model Content

[0005] To address the aforementioned problem—the difficulty of using vertical clamping plates to clamp stacked upper bars—this invention proposes a band saw feeding device. The device includes a transmission mechanism with a fixed frame and a movable frame mounted on its two long sides. The movable frame is driven by a lead screw. Both the fixed frame and the movable frame are equipped with clamping components, each including a clamping plate. The bottom edge of the clamping plate mounted on the fixed frame is rotatably connected to the fixed frame, and the bottom edge of the clamping plate mounted on the movable frame is also rotatably connected to the movable frame. Fixed plates are fixedly connected to both the fixed frame and the movable frame, corresponding to the clamping plates. A limit groove is provided on the surface of the clamping plate near the fixed plate. An adjusting lead screw is threaded onto the fixed plate, and the adjusting lead screw engages with the limit groove via a crossbar to drive the clamping plate to rotate.

[0006] A further feature of this invention is that the two ends of the adjusting screw are respectively located on both sides of the fixed plate, and an adjusting handle is provided at the end of the adjusting screw that is away from the clamping plate.

[0007] A further feature of this invention is that the two ends of the limiting groove are closed.

[0008] A further feature of this invention is that both the fixed frame and the movable frame are equipped with two sets of clamping components.

[0009] A further feature of this invention is that the movable frame includes a horizontal plate, the clamping assembly is mounted on the upper surface of the horizontal plate, and three prisms are provided on the lower surface of the horizontal plate. The prisms are positioned between any two adjacent rollers of the transmission mechanism, wherein the middle prism is connected to the drive screw via a slider. The transmission mechanism is also provided with two guide posts, which are arranged parallel to the drive screw. The other two prisms are slidably connected to the two guide posts respectively.

[0010] The beneficial effects of this utility model are as follows:

[0011] By using an adjusting screw to drive the clamping plate to rotate, the tilt angle of the clamping plate can be adjusted so that the clamping plate and the stacked bars have the same tilt angle, thereby achieving a better clamping effect on the stacked bars. Attached Figure Description

[0017] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0018] This utility model proposes a band saw feeding device, including a transmission mechanism 1. The transmission mechanism 1 uses rollers 12 for transmission. Specifically, the transmission mechanism 1 includes a rectangular frame 11, which is welded from profiles. Several rollers 12 are rotatably connected to the frame 11 to drive the bar stock.

[0019] A fixed frame 2 and a movable frame 3 are respectively installed on the two long sides of the frame 11. The fixed frame 2 and the movable frame 3 are correspondingly arranged. The fixed frame 2 is welded to the frame 11, and the movable frame 3 is installed through a drive screw 5. That is, the drive screw 5 is rotatably connected to the two long sides of the frame 11. A slider is threaded onto the drive screw 5, and the movable frame 3 is fixedly connected to the slider. A drive motor is also installed at one end of the drive screw 5. The drive motor drives the screw 5 to rotate, thereby driving the slider to slide along the drive screw 5, and further driving the movable frame 3 to slide along the direction of the drive screw 5.

[0020] Two sets of clamping components 4 are installed on both the fixed frame 2 and the movable frame 3, and the two sets of clamping components 4 on the fixed frame 2 are correspondingly set to the two sets of clamping components 4 on the movable frame 3. The clamping assembly 4 includes a clamping plate 41. The clamping plate 41 installed on the fixed frame 2 is rotatably connected to the fixed frame 2. The clamping plate 41 installed on the movable frame 3 is rotatably connected to the movable frame 3. Fixed plates 42 are welded on both the fixed frame 2 and the movable frame 3. The fixed plates 42 are set corresponding to the clamping plates 41. A limit groove 411 is welded on the side surface of the clamping plate 41 near the fixed plate 42. The two ends of the limit groove 411 are closed. An adjusting screw 43 is threadedly connected to the fixed plate 42. A crossbar 431 is rotatably connected to the end of the adjusting screw 43 near the limit groove 411. The crossbar 431 is engaged in the limit groove 411. That is, rotating the adjusting screw 43 can drive the crossbar 431 to move accordingly, thereby achieving the purpose of driving the clamping plate 41 to rotate and further adjusting the tilt angle of the clamping plate 41.

[0021] The two ends of the adjusting screw 43 are respectively set on both sides of the fixed plate 42, and the end of the adjusting screw 43 away from the clamping plate 41 is welded with an adjusting handle 432 to facilitate the adjustment of the adjusting screw 43.

[0022] The movable frame 3 includes a horizontal plate 31, which is positioned above the rollers 12. A clamping assembly 4 is mounted on the upper surface of the horizontal plate 31, and a clamping plate 41 mounted on the movable frame 3 is rotatably connected to the horizontal plate 31. Three prisms 32 are welded to the lower surface of the horizontal plate 31, positioned between any two adjacent rollers 12 so as not to affect the rotation of the rollers 12. The middle prism 32 is fixedly connected to the slider on the drive screw 5. Two guide posts 6 are also provided between the two long sides of the frame 11. The two ends of the guide posts 6 are welded to the frame 11. The guide posts 6 are parallel to the adjusting screw 43 and symmetrically arranged about the adjusting screw 43. The other two prisms 32 are slidably connected to the two guide posts 6 respectively.

[0023] It should be noted that the two guide columns 6 and the adjusting screw 43 are all located below the roller 12 to avoid affecting the rotation of the roller 12.

[0024] refer to Figure 4 The process of its use is as follows: the drive motor drives the drive screw 5 to rotate, which causes the slider to move the movable frame 3, and then the movable frame 3 moves towards the fixed frame 2, so that the clamping plate 41 on the fixed frame 2 and the clamping plate 41 on the movable frame 3 clamp the bottom bar material. Then, the adjustment handle 432 is rotated, which causes the adjustment screw 43 to drive the crossbar 431 to push the clamping plate 41 to rotate until it presses down on the upper bar material.

[0025] In summary, this utility model utilizes the adjusting screw 43 to drive the clamping plate 41 to rotate, thereby adjusting the tilt angle of the clamping plate 41 so that the clamping plate 41 and the stacked bars can have the same tilt angle, thus achieving a better clamping effect on the stacked bars.
