Description

Technical Field

[0001] The utility model relates to the technical field of angle cutting machine protection, in particular to a cutting blade guard for a pneumatic angle cutting machine. Background Art

[0002] Angle cutting machines are machines that perform 45° bevel or polygonal cutting on the corners of materials. They are suitable for processing picture frames, wood strips, boards and other items. Currently, most angle cutting machines use pneumatic drives to fix the cutting parts and use downward-pressed blades or high-speed rotating blades to complete the angle cutting operation.

[0003] When the existing angle cutting machine is not in use, its blade is often exposed to the outside, so it is easy for the worker to accidentally touch the blade when cleaning or maintaining the angle cutting machine, causing injuries to the worker, or the maintenance tool and the blade collide, causing the blade to be damaged. Therefore, we propose a pneumatic angle cutting machine cutting blade guard to solve the above problems. Utility Model Content

[0004] In view of the deficiency that the existing angle cutting machines lack protection for the blades when not in use, the utility model provides a pneumatic angle cutting machine cutting blade guard, which has the advantages of wrapping and protecting the blade and being adjustable according to different blade sizes, thereby solving the problems raised in the above-mentioned background technology.

[0005] To achieve the above objectives, the utility model is implemented through the following technical solutions: a pneumatic angle cutting machine cutting blade guard, comprising two symmetrically arranged first U-shaped parts, and a second U-shaped part slidably arranged inside the first U-shaped parts, the two first U-shaped parts are hinged and fixed, and a sealing plate is installed on one end of the two second U-shaped parts that are relatively far away;

[0007] The second U-shaped member includes a third shielding plate and a fourth shielding plate which are arranged parallel to each other, the third shielding plate is parallel to the first shielding plate, the bottom of the third shielding plate and the bottom of the fourth shielding plate are connected by a second arc plate, and the second arc plate is coaxially arranged with the first arc plate, and the height of the third shielding plate is greater than that of the fourth shielding plate;

[0008] A clamping mechanism is arranged between the third shielding plate and the fourth shielding plate to clamp and fix the second U-shaped member on the blade.

[0009] Preferably, at least two slide grooves are provided on the first shielding plate, and the slide grooves are arranged along the axial direction of the first arc-shaped plate. Slide blocks are slidably installed in the slide grooves, and the slide blocks are fixedly connected to the third shielding plate.

[0010] Preferably, limiting grooves are provided on both upper and lower sides of the slider, and the limiting grooves on both sides of the slider are clearance-matched with the upper and lower sides of the slide groove.

[0011] Preferably, the clamping mechanism includes two parallel clamps, the two clamps are close to each other, and the clamps are arranged along the axial direction of the second arc plate, the tops of the two clamps are connected with arc springs, the arc springs are arranged tangent to the clamps, the top of one of the arc springs is fixed on the third shielding plate, and the top of the other arc spring is fixed on the fourth shielding plate.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figures 1 to 4 The utility model provides a technical solution: a pneumatic angle cutting machine cutting blade guard, comprising two symmetrically arranged first U-shaped parts, and a second U-shaped part slidably arranged inside the first U-shaped parts, the two first U-shaped parts are hinged and fixed, and a sealing plate 7 is installed on the relatively far ends of the two second U-shaped parts. When the blade is placed inside the second U-shaped part, the blade can wrap its blade edge through the second U-shaped part and the sealing plate 7 to achieve the protection of the blade; if the size of the guard does not match the blade, the second U-shaped part can be pulled to slide the second U-shaped part inside the first U-shaped part, thereby adjusting the distance between the two sealing plates 7, so that the guard can be used for blades of different sizes, and if the blade to be used is an arc blade or an "L"-shaped blade, the guard can be rotated and bent through the hinge of the two first U-shaped parts for normal use.

[0022] The first U-shaped member includes a first shielding plate 1 and a second shielding plate 3 arranged in parallel with each other, the bottom of the first shielding plate 1 and the bottom of the second shielding plate 3 are connected by a first arc plate 2, and the height of the first shielding plate 1 is greater than that of the second shielding plate 3; the second U-shaped member includes a third shielding plate 4 and a fourth shielding plate 6 arranged in parallel with each other, the third shielding plate 4 is parallel to the first shielding plate 1, the bottom of the third shielding plate 4 and the bottom of the fourth shielding plate 6 are connected by a second arc plate 5, and the second arc plate 5 is coaxially arranged with the first arc plate 2, and the height of the third shielding plate 4 is greater than that of the fourth shielding plate 6. If the placement table of the angle cutting machine is close to the blade, when installing the shield, the shorter fourth shielding plate 6 can be first placed toward the blade, and then the shield can be installed on the blade, which can not only protect the blade but also facilitate the installation of the shield on the blade.

[0023] A clamping mechanism is provided between the third shielding plate 4 and the fourth shielding plate 6 to clamp and fix the second U-shaped member on the blade.

[0024] When the pneumatic angle cutter cutting blade guard is used, a worker holds the bottom of the first U-shaped member and moves the cutting blade guard according to the blade of the angle cutter (such as Figure 4 The position of the second U-shaped part is adjusted, and then the fourth baffle plate 6 is sent to the bottom of the blade to face the blade, and then the first U-shaped part is lifted upward to clamp the guard on the blade to complete the installation of the guard.

[0025] Furthermore, at least two slide grooves 8 are provided on the first shielding plate 1, and the slide grooves 8 are arranged along the axial direction of the first curved plate 2. Slide blocks 9 are slidably installed in the slide grooves 8, and the slide blocks 9 are fixedly connected to the third shielding plate 4. The second U-shaped member can be moved along the axial direction of the first curved plate 2 to adjust the length of the shield.

[0026] Furthermore, in order to ensure the stability of the sliding of the second U-shaped part in the first U-shaped part and avoid the second U-shaped part from shaking in the first U-shaped part, limit grooves 10 are opened on the upper and lower sides of the slider 9, and the limit grooves 10 on both sides of the slider 9 are matched with the upper and lower clearances of the slide groove 8.

[0027] Furthermore, if Figure 3 As shown, the clamping mechanism includes two parallel clamping plates 12, the two clamping plates 12 are closely attached to each other, and the clamping plates 12 are arranged along the axis direction of the second arc-shaped plate 5, and the tops of the two clamping plates 12 are connected with arc-shaped spring pieces 11, and the arc-shaped spring pieces 11 are arranged tangent to the clamping plates 12, and the top of one arc-shaped spring piece 11 is fixed on the third shielding plate 4, and the top of the other arc-shaped spring piece 11 is fixed on the fourth shielding plate 6. Through the close contact of the two clamping plates 12, when the blade is placed between the two clamping plates 12, the volume thickness of the blade will push the clamping plates 12 to open, and at this time, the clamping plates 12 will clamp the blade under the elastic action of the arc-shaped spring pieces 11, thereby fixing the shield on the blade.

[0028] Furthermore, a compression spring 13 is installed on the side where the third shielding plate 4 and the fourth shielding plate 6 are relatively close, and the other end of the compression spring 13 is fixedly connected to the corresponding clamping plate 12. When the blade is inserted between the two clamping plates 12, the deformation of the compression spring 13 can further increase the pressure of the clamping plate 12 on the blade, thereby improving the clamping effect of the clamping plate 12 on the blade.

[0029] In order to prevent the surface smoothness of the blade from affecting the clamping of the clamping plate 12 on the blade, anti-skid rubber pads are installed on the surface of the arc-shaped spring piece 11 and the surface of the clamping plate 12 to reduce the probability of the guard sliding off the blade.
