Abstract
Description
Technical Field
[0001] This utility model relates to the field of band saw technology, and more specifically, to a metal band saw. Background Technology
[0002] Band saws primarily use saw bands or saw blades as cutting tools to cut metal materials such as alloy structural steel, medium carbon steel, and stainless steel. The machining precision of band saws is generally not very high, and they are mostly used in material preparation workshops to cut various plates and profiles.
[0003] When cutting sheet metal, existing band saws first place the sheet metal on the clamps of the band saw and clamp it in place. Then, the saw band or saw blade moves and rotates along the band saw to cut the profile on the clamps. However, in actual use, most of the clamps on existing band saws clamp the sheet metal by bringing the clamping plates close together. If the sides of the sheet metal are irregular, clamping the sheet metal by bringing the clamping plates close together can cause the sheet metal to wobble during the sawing process, thus affecting the sawing effect. Utility Model Content
[0004] The purpose of this invention is to provide a metal band saw to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A metal band saw includes a frame and a saw base movably mounted on the frame. The saw base is provided with a sawing component. A saw table is provided on the upper side of the frame. The sawing component is located on one side of the saw table. A clamping component for fixing the plate is provided on the saw table. A drive component for driving the saw base to move is provided on the frame.
[0007] The clamping assembly includes several mounting seats that are movably mounted on the saw table. Opposite sliding seats are slidably mounted on the mounting seats. The sliding seats are provided with liftable pressure plates, which are used to press and fix the sheet metal. The pressure plates are rotatably mounted on the sliding seats.
[0008] Furthermore, the upper side of the mounting base is provided with a T-shaped groove along its length, the sliding base is slidably disposed in the groove, and a hand-tightening bolt for fixing the sliding base is threaded onto the sliding base.
[0009] Furthermore, the bottom sidewall of the mounting base extends outward to form a mounting section, which is fixedly mounted to the saw table by screws.
[0010] Furthermore, the sliding seat is provided with a column, and the column is provided with a threaded hole along its height direction;
[0011] The pressure plate component includes a column tube fitted over the column and a pressure block rotatably installed at the top of the column tube.

[0012] Furthermore, the top end of the column is provided with a connecting cylinder, the pressure block is provided with an installation hole, and the connecting cylinder is externally threaded with a nut for pressing the pressure block onto the top end of the column.
[0013] Furthermore, the drive assembly includes a lead screw rotatably mounted on the bed frame, the lead screw being threaded through the saw seat, and a motor for driving the lead screw to rotate is provided on one side wall of the bed frame.
[0014] Furthermore, the bed frame is equipped with a collection box for collecting cutting fluid.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] This invention, through the movable arrangement of the mounting base on the saw table, allows for adjustment of the spacing between adjacent mounting bases, enabling the fixing of plates of different lengths onto the mounting bases. The sliding base moves along the mounting base to adjust the spacing between the pressure plates, allowing the clamping assembly to press and fix plates of different widths. Simultaneously, when one side of the plate is irregular, the pressure plates are rotated to change their pressing position. Through this structure, the clamping assembly can press and fix different plates, improving the applicability of the band saw and ensuring better plate fixation for optimal sawing results.

[0027] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are merely illustrative of this utility model and are not intended to limit it.
[0028] The following is in conjunction with the appendix Figures 1-5 This embodiment will be described in further detail.
[0029] like Figure 1 and Figure 2 As shown, a metal band saw in this embodiment includes a frame 100 and a saw base 110 movably mounted on the frame 100. The saw base 110 is equipped with a sawing assembly. Specifically, in conjunction with... Figure 5 As shown, the saw holder 110 is roughly U-shaped and vertically arranged, with its lower end slidably arranged inside the bed frame 100. In order to realize the sliding installation of the saw holder 110 on the bed frame 100, a slide rail for installing the saw holder 110 is provided on one side of the bed frame 100 along its length.
[0030] The saw base 110 has mounting grooves 501 at both ends on the same side. The sawing assembly includes saw wheels 511 that are rotatably disposed in the corresponding mounting grooves 501. A saw blade 520 is sleeved between the saw wheels 511. Since the lower end of the saw base 110 is located inside the bed frame 100, the saw blade 520 is vertically installed through the bed frame 100.
[0031] Specifically, in order to achieve the rotation of the saw blade 520, a drive motor is provided on the saw base 110 located in the bed frame 100. The output shaft of the drive motor is connected to the corresponding saw wheel 511 through a reduction gearbox, thereby better driving the saw blade 520 to rotate for sawing the subsequent board.
[0032] In this embodiment, a saw table 101 is provided on the upper side of the bed frame 100. Specifically, the width of the saw table 101 is smaller than the width of the bed frame 100. Thus, when the saw table 101 is installed on the upper side of the bed frame 100, a space is formed between one side of the saw table 101 and the rear side of the bed frame 100 for sliding installation of the saw base 110. This allows the saw base 110 to be set on the bed frame 100 on one side of the saw table 101. The saw table 101 is provided with a clamping assembly for fixing the board, and the bed frame 100 is provided with a driving assembly for driving the saw base 110 to move.
[0033] In this embodiment, the metal sheet to be cut is fixedly installed on the saw table 101 by the clamp assembly. At this time, the drive motor is started to make the saw blade 520 rotate. The drive assembly drives the saw base 110 to move toward one end of the bed frame 100 so that the saw blade 520 completes the sawing of the sheet during the movement. After the sawing of the sheet is completed, the drive assembly drives the saw base 110 to reset so that it can saw the next sheet.
[0034] It should be noted that, in order to ensure the sawing effect of the saw blade 520 on the board, in this embodiment, the saw holder 110 is also provided with a cutting fluid spraying assembly. The cutting fluid spraying assembly is used to spray cutting fluid onto the sawing position of the saw blade 520 on the board so as to cool down the sawing position and thus ensure the sawing of the saw blade 520.
[0035] Specifically, in order to prevent the cutting fluid from flowing outside the bed frame 100, in this embodiment, the bed frame 100 is provided with a collection box 140 for collecting the cutting fluid.
[0036] In this embodiment, to achieve the reciprocating movement of the saw holder 110, the drive assembly includes a lead screw 130 rotatably mounted on the bed frame 100. The two ends of the bed frame 100 are fixedly mounted on fixed seats, and the lead screw 130 is rotatably mounted between the fixed seats via bearings. The lead screw 130 is threaded through the saw holder 110. Since the saw holder 110 is slidably mounted on the slide rail, the forward and reverse rotation of the lead screw 130 can drive the saw holder 110 to reciprocate along the lead screw 130. In order to achieve the forward and reverse rotation of the lead screw 130, a servo motor 131 for driving the lead screw 130 to rotate is provided on one side wall of the bed frame 100.
[0037] Combination Figure 3 As shown, in this embodiment, the clamping assembly includes several mounting seats 120 that are movably mounted on the saw table 101. Opposite sliding seats 310 are slidably mounted on the mounting seats 120. The sliding seats 310 are provided with liftable pressure plate members 320. The pressure plate members 320 are used to press and fix the plate. The pressure plate members 320 are rotatably mounted on the sliding seats 310.
[0038] In this embodiment, when fixing the plate, the plate is placed overlapping on the mounting base 120. By moving the sliding seats 310 on both sides, the pressure plate 320 is moved to the upper part of both sides of the plate. At this time, the plate is pressed by the pressure plate 320 to fix the plate on the mounting base 120.
[0039] Specifically, in order to accommodate the saw holder 110 driving the saw blade 520 to move, the mounting base 120 is set in two sections. The sliding seats 310 on both sides of the mounting base 120 are slidably set so that the sliding seats 310 can move along the mounting base 120, thereby adjusting the spacing between the pressure plate parts 320, so that the clamping assembly can press and fix plates of different widths.
[0040] In this embodiment, the movable arrangement of the mounting base 120 allows the spacing between adjacent mounting bases 120 to be adjusted, thereby enabling plates of different lengths to be fixedly installed on the mounting base 120.
[0041] When one side of the plate is irregular, the pressure plate 320 is rotatably mounted on the sliding seat 310. In this case, the pressure plate 320 is rotated to change the position of pressing the plate, thereby improving the applicability of the clamping assembly.
[0042] In actual use, the upper side of the saw table 101 is provided with multiple mounting holes (not shown in the figure) along the moving direction of the saw base 110. The bottom side wall of the mounting base 120 extends outward to form a mounting part 302. The mounting part 302 is fixedly installed in the corresponding mounting hole by screws, so that the mounting base 120 can be moved and installed on the saw table 101.
[0043] Combination Figure 3 and Figure 4 As shown, in this embodiment, in order to better realize the sliding adjustment of the sliding seat 310 on the mounting seat 120, the upper side of the mounting seat 120 is provided with a T-shaped groove 301 along its length direction. The sliding seat 310 is slidably disposed in the groove 301, and a hand-tightening bolt 410 for fixing the sliding seat 310 is threadedly connected to the sliding seat 310.
[0044] The sliding seat 310 has a connecting hole, and the hand-tightening bolt 410 passes through the slide groove 301 and is threaded into the connecting hole. Tightening the hand-tightening bolt 410 causes its lower end to press against the bottom wall of the slide groove 301 to fix the sliding seat 310. Loosening the hand-tightening bolt 410 releases the pressure on the bottom wall of the slide groove 301, allowing the sliding seat 310 to slide along the slide groove 301.
[0045] Specifically, in order to improve the effect of the hand-tightening bolt 410 in fixing the sliding seat 310, in this embodiment, a rubber pad is provided at the end of the hand-tightening bolt 410 that presses against the bottom wall of the slide groove 301. The rubber pad increases the friction between the two, which can improve the effect of fixing the sliding seat 310.
[0046] In this embodiment, a column 401 extending through the sliding groove 301 is fixedly provided on the sliding seat 310, and a threaded hole 402 is provided in the column 401 along its height direction.
[0047] The pressure plate component 320 includes a column tube 321 sleeved outside the column 401 and a pressure block 322 rotatably installed at the top of the column tube 321. The column tube 321 is provided with a rotatable long rod bolt 420, which is threaded into the threaded hole 402 to realize the lifting and lowering of the column tube 321.
[0048] In this embodiment, the column 401 is square column-shaped, and the column tube 321 is also square column-shaped. It is slidably sleeved on the outside of the column 401, so that it can only move up and down along the column 401 and cannot rotate circumferentially. The long rod bolt 420 is rotatably installed at the top of the column tube 321 through the bearing, and the upper end of the long rod bolt 420 is extended and a screw cap is installed on the upper end to facilitate the operator to screw the long rod bolt 420 to rotate.
[0049] The column 321 is raised and lowered by a long bolt 420 threaded into a threaded hole 402, and the distance the long bolt 420 extends into the threaded hole 402 is used to drive the pressure block 322 to press the plate.
[0050] In this embodiment, to better achieve the rotational adjustment of the pressure block 322 on the column cylinder 321, a connecting cylinder 431 is fixedly provided at the top end of the column cylinder 321. The connecting cylinder 431 is hollow and communicates with the inside of the column cylinder 321. It has threads on its exterior, and a long bolt 420 passes through the connecting cylinder 431. The pressure block 322 has a through hole 441, and a nut 450 for pressing the pressure block 322 onto the top end of the column cylinder 321 is threaded onto the connecting cylinder 431. With this structure, when the pressure block 322 needs to be rotated, loosening the nut 450 releases the pressure on the pressure block 322, allowing for rotational adjustment and adjustment of the position where the pressure block 322 presses against the plate, which is beneficial for practical use. When the pressure block 322 needs to be fixed, tightening the nut 450 presses the pressure block 322 and fixes it at the top end of the column cylinder 321, allowing for better pressing and fixing of the plate.
[0051] In summary, the above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall fall within the scope of the patent of the present utility model.
