Technical Field

[0001] This utility model belongs to the field of power tool technology, specifically, it relates to a profile cutting machine with adjustable blade angle. Background Technology

[0002] Profiles are objects with specific geometric shapes made from iron, steel, alloys, and other materials with certain strength and toughness through processes such as rolling, extrusion, and casting. A profile cutting machine is an essential device for cutting profiles; it can divide profiles into sections according to specific size and shape requirements.

[0003] The blades of profile cutting machines are generally made of resin sintering and alloy. Due to the elasticity of the material, these blades tend to deviate to the left during cutting. Currently, most of these blades are controlled by the worker's feel, but this does not fundamentally solve the problem. Utility Model Content

[0025] Specific embodiments of this application have been described in conjunction with the accompanying drawings and the following description to teach those skilled in the art how to make and use this application. For the purpose of teaching the principles of the application, the following conventional aspects have been simplified or omitted. Those skilled in the art should understand that variations derived from these embodiments fall within the scope of this application. Those skilled in the art should understand that the following features can be combined in various ways to form multiple variations of this application. Terms such as “upper,” “lower,” “left,” “right,” “middle,” and “one” used in this application are merely for clarity of description and are not intended to limit the scope of implementation of this utility model.

Therefore, this application is not limited to the specific embodiments described below, but only to the claims and their equivalents.

[0026] like Figures 1 to 3 As shown, this embodiment relates to a profile cutting machine with an adjustable blade angle, which includes a base 1 and a cutting machine body 2. The base 1 serves as the support platform for the cutting machine body 2, is made of steel, and is rectangular in shape. The length direction of the base 1 is denoted as the X-axis direction, and the width direction is denoted as the Y-axis direction. The cutting machine body 2 is installed along the X-axis direction. The cutting machine body 2 is connected to the top of the base 1 through a rotation adjustment mechanism. The rotation adjustment mechanism includes a fixed bracket 3 and an adjusting bracket 4. The fixed bracket 3 is fixedly installed on the base 1. The adjusting bracket 4 is rotatably connected to the fixed bracket 3 along the Y-axis direction of the base 1 and is limited by a limiting member 5 and positioned by a positioning member 6. The cutting machine body 2 and the adjusting bracket 4 are rotatably connected along the X-axis direction of the base 1. That is to say, the rotation plane formed by the adjusting bracket 4 and the fixed bracket 3 is a perpendicular plane to the rotation plane formed by the cutting machine body 2 and the adjusting bracket 4.

[0027] like Figures 2 to 5As shown in the embodiment of this application, the fixed bracket 3 includes a corner plate 31 and a cylindrical boss 32. The cylindrical boss 32 protrudes from the rear side of the corner plate 31, and the lower part of the corner plate 31 is fixed to the base 1 by bolts. The cylindrical boss 32 and the corner plate 31 are an integral structure. The adjusting bracket 4 includes a horizontal plate 41 and connecting arms 42 located on both sides of the horizontal plate 41. The horizontal plate 41 is provided with a rotating groove 43, and the cylindrical boss 32 is located in the rotating groove 43. During the adjustment process, the corner plate 31 and the cylindrical boss 32 are fixed. The cylindrical boss 32 plays a supporting role and serves as the rotation center of the adjusting bracket 4. The rotating groove 43 and the cylindrical boss 32 are both provided with screw holes 33 at their centers. The fixing bolts 34 are installed in the screw holes 33 to connect and fix the adjusting bracket 3 and the fixed bracket 4.

[0028] In addition, a limiting platform 44 is horizontally set on the outer side of the two connecting arms 42. In this embodiment, the limiting member 5 is a limiting bolt. The limiting bolt is vertically installed on the limiting platform 44. The limiting bolt passes through the limiting platform 44 and its lower end abuts against the base 1. During the adjustment process, the rotation angle of the adjusting bracket 4 can be limited by simply turning the limiting bolt. Specifically, when the limiting bolt on one of the limiting platforms 44 moves down, the height of the limiting platform 44 at that point increases, and conversely, the height of the other limiting platform 44 decreases, thereby causing the cutting machine body 2 and the blade to deflect.

[0029] Arc-shaped grooves 45 are respectively provided on both sides of the rotating groove 43 on the horizontal plate 41, and positioning grooves 35 are respectively provided on the corner plate 31 corresponding to the arc-shaped grooves 45. The positioning component 6 is a positioning bolt. The positioning bolt passes through the arc-shaped groove 45 and is inserted into the positioning groove 35. After the blade angle is adjusted, it is positioned by the positioning bolt. The fixing bolt 34 is installed after the positioning bolt. In this embodiment, the adjustment angle of the cutting machine body 2 is -10° to 10°.

[0030] The cutting machine body 2 is rotatably connected to the connecting arm 42 via the frame 21. A rotating shaft 22 is installed at the bottom of the frame 21, and a shaft hole 48 is provided on the connecting arm 42. The rotating shaft 22 is inserted into the shaft hole 48. A crossbar 46 is connected between the two connecting arms 42, and a limiting baffle 47 is provided on the crossbar 46. A limiting post 23 is provided on the frame 21. When the cutting machine body 2 moves downward, the lower end of the limiting post 23 abuts against the limiting baffle 47.

[0031] like Figure 1 As shown, a rotating guide rail 7 is installed on the base 1. The rotating guide rail 7 can adjust the cutting angle of the groove. An adjustable clamp 8 is provided on one side of the rotating guide rail 7 along the X-axis of the base 1. The adjustable clamp 8 cooperates with the rotating guide rail 7 to fix the profile.

[0032] As those skilled in the art will readily conceive, any modifications, equivalent substitutions, improvements, etc., made using the concept and principles of this application should be included within the scope of the claims of this application.
