Description

Technical Field

[0001] The utility model relates to the technical field of band saw blade processing, in particular to a band saw blade sandblasting device. Background Art

[0002] like Figure 1 As shown, the saw blade 10 needs to be ground at the weld position 9 to remove welding slag. After grinding, the surface of the weld position 9 will have color difference. In order to eliminate the color difference, sandblasting is generally performed, and the fatigue performance at the weld position 9 can be improved by sandblasting.

[0003] like Figure 1 As shown, the existing sandblasting equipment includes a lower pressing frame 1, an upper pressing frame 7, and a spray gun 8 installed at the upper and lower parts. The saw blade 10 is displaced along the X direction on the lower pressing frame 1, and the upper pressing frame 7 is pressed down in the Z direction to clamp the saw blade 10 together with the lower pressing frame 1. The spray guns 8 arranged at the upper and lower sides of the welding position 9 of the saw blade 10 are respectively arranged. The spray guns 8 are repeatedly swung back and forth to spray sand particles, thereby realizing the operation of the sandblasting process.

[0004] There are two types of sandblasting paths for the spray gun 8: one is to move back and forth repeatedly, and the other is to swing in an eight-shaped shape. Both of these methods will cause differences in the uniformity of sandblasting on the upper and lower surfaces of the saw blade 10, resulting in slight deformation of the sandblasting position (slight convexity or concaveness in the sandblasting area). This deformation will cause the saw blade 10 to fluctuate during the cutting process, thereby affecting the product molding quality. Utility Model Content

[0005] The utility model aims to provide a band saw blade sandblasting device which can avoid deformation during the sandblasting process.

[0006] The technical solution of the utility model is: a band saw blade sandblasting equipment, including a lower pressing frame and a first positioning mechanism and a second positioning mechanism for applying a clamping force in the Z direction, the first positioning mechanism and the second positioning mechanism are respectively arranged on both sides of the lower pressing frame in the X direction, and a band saw blade clamping gap is formed between the first positioning mechanism and the lower pressing frame and between the second positioning mechanism and the lower pressing frame, and a tensioning mechanism is arranged on the side of the second positioning mechanism for driving the second positioning mechanism to move in the X direction in a push-pull manner, and the tensioning mechanism is arranged away from the first positioning mechanism.

[0007] In the above scheme, a tensioning mechanism is added to drive the clamped second positioning mechanism to move in the X direction, thereby tensioning the saw blade. Sandblasting is performed after the saw blade is tensioned, which reduces the deformation of the saw blade during the sandblasting process.

[0008] Preferably, the first positioning mechanism includes a first fixed plate installed beside the lower pressure frame, a second fixed plate vertically connected to the first fixed plate, and a first driving source installed on the second fixed plate; the first driving source is telescopic in the Z direction and is connected to the first pressure plate at its telescopic end, and the first pressure plate can apply the clamping force to the first fixed plate.

DETAILED DESCRIPTION

[0019] The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict. For the convenience of description, if the words "upper", "lower", "left" and "right" appear in the following text, they only indicate that the upper, lower, left and right directions are consistent with the drawings themselves, and do not limit the structure.

[0020] like Figure 2 As shown, a band saw blade sandblasting device provided in this embodiment includes a lower pressing frame 1, a first positioning mechanism 2, a second positioning mechanism 3, a tensioning mechanism 4, a sliding block 5, a sliding rail 6 and a spray gun 8.

[0021] The pressing frame 1 is provided with a first positioning mechanism 2 and a second positioning mechanism 3 on both sides of the X direction. A tensioning mechanism 4 is provided on the side of the second positioning mechanism 3 away from the first positioning mechanism 2 .

[0022] The first positioning mechanism 2 includes a first fixing plate 21 installed beside the lower pressing frame 1, a second fixing plate 23 vertically connected to the first fixing plate 21, and a first driving source 22 installed on the second fixing plate 23. The upper surface of the first fixing plate 21 is flush with the upper surface of the lower pressing frame 1, or the upper surface of the first fixing plate 21 extends beyond the upper end of the upper surface of the lower pressing frame 1. The saw blade 10 passes through. The first driving source 22 is a cylinder, which is telescopic in the Z direction and connected to the first pressing plate 24 at its telescopic end. The first driving source 22 is telescopic to drive the first pressing plate 24 to apply the clamping force to the first fixing plate 21 to clamp the saw blade 10 on the first fixing plate 21.

[0023] The second positioning mechanism 3 includes a third fixed plate 31 installed beside the lower pressing frame 1, and a mounting seat 32 connected to the third fixed plate 31. The upper surface of the third fixed plate 31 is flush with the upper surface of the lower pressing frame 1, or the upper surface of the third fixed plate 31 extends beyond the upper end of the upper surface of the lower pressing frame 1. The lower surface of the bottom of the mounting seat 32 is connected to the slider 5, and one end of the bottom of the mounting seat 32 is connected to the third fixed plate 31. A second driving source 33 is provided on the mounting seat 32, and the second driving source 33 is a cylinder, which is telescopic in the Z direction and connected to the second pressing plate 34 at its telescopic end. The second driving source 33 is telescopic to drive the second pressing plate 34 to apply the clamping force to the third fixed plate 31 to clamp the saw blade 10 on the third fixed plate 31.

[0024] The tensioning mechanism 4 includes a fixed seat 41 connected to the side of the lower pressing frame 1 and a third driving source 42 installed on the fixed seat 41. The fixed seat 41 is L-shaped, and its bottom plate is fixed to the side of the lower pressing frame 1, and the slide rail 6 is installed on the upper surface of the bottom plate. The slider 5 is slidably connected to the slide rail 6. The third driving source 42 is installed on the vertical plate of the L-shaped fixed seat 41. The third driving source 42 is a cylinder, which is telescopic in the X direction and its telescopic end is connected to the mounting seat 32 of the second positioning mechanism 3. The mounting seat 32 is driven by the telescopic third driving source 42 in a push-pull manner, thereby driving the entire second positioning mechanism 3 to move in the X direction, and the slider 5 and the slide rail 6 play a guiding role when the second positioning mechanism 3 moves.

[0025] When in use, the saw blade 10 is placed on the lower pressing frame 1 and the upper surfaces of the first fixing plate 21 and the third fixing plate 31, and the saw blade 10 is displaced in the X direction. When the weld position 9 of the saw blade 10 is placed at the spray gun 8, the saw blade 10 stops. The first driving source 22 and the second driving source 33 are started to drive the first pressing plate 24 and the second pressing plate 34 to move downward and press the saw blade 10. The third driving source 42 is started again to drag the second positioning mechanism 3 and the end of the clamped saw blade 10 to move rightward in the X direction to tension the saw blade 10. The spray gun 8 is started again to perform sandblasting at the weld position 9. Since the saw blade 10 is sprayed under tension, the deformation amount will be greatly reduced.

[0026] Sandblasting after tensioning can effectively avoid deformation of the blasting position after sandblasting. The deformation of sandblasting is about 0.2-0.4mm when not tensioned, and the deformation of sandblasting can be controlled within 0.02mm after tensioning.
