Description

Technical Field

[0001] The utility model relates to the field of metal profile processing, in particular to a special grinding machine for metal profile processing. Background Art

[0002] During the processing of metal profiles, it is necessary to grind the metal profiles. For example, the Chinese patent with publication number: CN117718834A discloses an end burr grinder for aluminum profile production, which can grind the end of the aluminum profile by setting a grinding mechanism, drive the aluminum profile to move and convey by a conveyor belt mechanism, adjust the position of the mounting plate by a position adjustment mechanism to adapt to the grinding of aluminum profiles of different lengths, drive the pressing plate mechanism to rise and fall by an electric telescopic rod to clamp and fix aluminum profiles of different widths, adjust the state of the pressing mechanism by a push plate mechanism, and clamp the aluminum profile by a clamping mechanism, thereby improving the efficiency of aluminum profile grinding.

[0003] However, when the push plate mechanism pushes the profile in the clamping mechanism to move to one side of the grinder, the profile and the clamping mechanism will move relative to each other, causing wear between the profile and the clamping mechanism, and the debris generated during grinding will remain on the conveyor belt, affecting subsequent processing. Utility Model Content

[0004] In order to overcome the disadvantage that when the push plate mechanism of the existing profile grinder pushes the profile in the clamping mechanism to move to one side of the grinder, the profile and the clamping mechanism will move relative to each other, causing wear between the profile and the clamping mechanism, the utility model provides a special grinder for metal profile processing.

[0005] Technical solution: A special grinder for metal profile processing, including an end face grinder; also including an electric push rod, a connecting plate, a pressure plate, an airbag, a motor and a round tube; the end face grinder is connected to the electric push rod; the telescopic end of the electric push rod is fixedly connected to a connecting plate; the connecting plate is rotatably connected to two pressure plates; each pressure plate is connected to an airbag; the connecting plate is fixedly connected to two motors, and the output shaft of the motor is fixedly connected to the corresponding pressure plate; each pressure plate passes through and is fixedly connected to a round tube, and the round tube is connected to the airbag.

[0006] More preferably, the surface of the airbag is coated with a wear-resistant layer.

[0007] More preferably, the airbag is detachably connected to the pressure plate.

[0008] More preferably, it also includes a dust cover, a spring rod and a baffle; the connecting plate is fixedly connected to the inverted U-shaped dust cover; the end grinder is connected to the spring rod; the telescopic end of the spring rod is fixedly connected to the baffle, and the baffle and the dust cover are in contact with each other.

[0009] More preferably, the dust cover is provided with an arc-shaped edge portion.

[0010] More preferably, a suction pipe is further included; the end surface grinder is connected to the suction pipe.

[0011] Compared with the prior art, the utility model has the following advantages: the utility model controls the motor to start, and drives the pressure plate to flip downward through the output shaft of the motor until the airbag pre-clamps the profile body, and then controls the cylinder to drive the push plate to move to the right, so that the push plate pushes the profile body to move to the right until the profile body contacts the grinding wheel of the grinder, and sliding occurs between the profile body and the airbag, and the friction between the profile body and the pressure plate is reduced by the airbag, thereby avoiding wear of the profile body.

[0012] After the airbag expands to clamp the profile body, the utility model controls the motor to start again, and drives the pressure plate to continue to flip downward through the output shaft of the motor, so that the pressure plate continues to squeeze the airbag, causing the airbag to adaptively deform and contact the left and right sides of the profile body, so that the airbag covers the narrow space between the round hole and the outside of the profile body and the conveyor belt of the conveyor, thereby improving the collection efficiency of debris.

[0020] Example 1

[0021] A special grinding machine for metal profile processing, such as Figure 1-Figure 5 As shown, an end face grinding machine is included;

[0022] It also includes an electric push rod 101, a connecting plate 102, a pressure plate 103, an airbag 104, a motor 105 and a round tube 106; the end surface grinder is connected to the electric push rod 101; the telescopic end of the electric push rod 101 is fixedly connected to the connecting plate 102; the connecting plate 102 is rotatably connected to two symmetrically distributed pressure plates 103; an airbag 104 is connected to the inner side of each pressure plate 103; the connecting plate 102 is bolted to two motors 105, and the output shaft of the motor 105 is fixedly connected to the corresponding pressure plate 103; each pressure plate 103 is penetrated by and fixedly connected to a round tube 106, and the round tube 106 is connected to the airbag 104.

[0023] The end face grinder includes a conveyor 1, a mounting plate 2, a cylinder 3, a push plate 4, a grinder 5 and a limit plate 6; the conveyor 1 is fixedly connected to the mounting plate 2, and the mounting plate 2 is bolted to the electric push rod 101; the cylinder 3 is bolted to the left side of the mounting plate 2; the push plate 4 is fixed to the telescopic end of the cylinder 3; the grinder 5 is bolted to the right side of the mounting plate 2, and the grinder 5 is composed of a driving machine and a grinding wheel, and the output shaft of the driving machine is fixedly connected to the grinding wheel; the conveyor 1 is fixedly connected to the limit plate 6.

[0024] The surface of the airbag 104 is coated with a wear-resistant layer to increase the wear resistance between the airbag 104 and the profile body 7 and improve the service life of the airbag 104.

[0025] The airbag 104 is connected to the pressure plate 103 by a buckle, which facilitates maintenance and replacement of the airbag 104 .

[0026] It also includes a dust cover 107, a spring rod 108 and a baffle 109; the connecting plate 102 is fixedly connected with an inverted U-shaped dust cover 107; the mounting plate 2 is fixedly connected with the spring rod 108; the telescopic end of the spring rod 108 is fixedly connected with the baffle 109, and the baffle 109 and the dust cover 107 are in contact with each other.

[0027] The dust cover 107 is provided with an arc-shaped edge portion 1071 to reduce the resistance between the dust cover 107 and the side of the baffle 109 , so as to facilitate the dust cover 107 to move down and snap into the side of the baffle 109 .

[0028] It also includes a suction pipe 1010 ; the push plate 4 is fixedly connected to the suction pipe 1010 .

[0029] When in use, the external pump is connected to the circular tube 106, and initially the circular tube 106 is used to inflate the airbag 104, so that the airbag 104 expands. Subsequently, the profile body 7 to be polished is manually placed on the conveyor 1, and then the conveyor 1 is controlled to drive the profile body 7 to move forward, and the limit plate 6 limits the end of the profile body 7 to be polished, so that the end of the profile body 7 to be polished is aligned with the left side of the limit plate 6 to prevent the end of the profile body 7 to be polished from extending excessively to the right. When the profile body 7 moves to the bottom of the connecting plate 102, the electric push rod 101 is controlled to drive the connecting plate 102 and the pressing plate 103 to move down to a predetermined distance. Then, the motor 105 is controlled to start, and the pressing plate 103 is driven to flip downward by the output shaft of the motor 105 until the airbag 104 pre-clamps the profile body 7. Figure 4 As shown, the air cylinder 3 is then controlled to drive the push plate 4 to move rightward, so that the push plate 4 pushes the profile body 7 to move rightward until the profile body 7 contacts the grinding wheel of the grinder 5, and sliding occurs between the profile body 7 and the airbag 104. The airbag 104 reduces the friction between the profile body 7 and the pressure plate 103 to avoid wear of the profile body 7. Moreover, since the airbag 104 is made of a deformable material, the airbag 104 can adapt to profile bodies 7 of different sizes, thereby improving adaptability.

[0030] The grinding process of the profile body 7 will produce a lot of debris and impurities, which may easily cause debris splashing. Therefore, when the connecting plate 102 moves downward, the dust cover 107 is driven downward to move, and the dust cover 107 is stuck to the right side of the baffle 109, and then the baffle 109 and the dust cover 107 are used to protect the debris and impurities splashed during the grinding process. The spring rod 108 keeps the baffle 109 and the dust cover 107 in close contact at all times under the action of its own elastic force to prevent vibration during the grinding process from causing a gap between the baffle 109 and the dust cover 107, so that the splashing flies out from the gap between the baffle 109 and the dust cover 107. The debris generated during the grinding process will fly into the triangular space formed by the profile body 7 and the conveyor belt of the conveyor 1. Therefore, the external air pump is controlled to start, and the triangular space formed by the profile body 7 and the conveyor belt of the conveyor 1 is sucked through the suction pipe 1010 to draw away and collect the debris.

[0031] And because there is a circular hole 71 in the profile body 7, the debris that enters the triangular space formed by the profile body 7 and the conveyor belt of the conveyor 1 is easy to fly out from the circular hole 71, and at the same time the suction force of the suction pipe 1010 will be reduced, and the debris generated by grinding will fly into the narrow space between the outer side of the profile body 7 and the conveyor belt of the conveyor 1, and it is not easy to be collected by the suction pipe 1010. Therefore, after the airbag 104 expands and clamps the profile body 7, the control motor 105 is started again, and the output shaft of the motor 105 drives the pressure plate 103 to continue to flip downward, so that the pressure plate 103 continues to squeeze the airbag 104, so that the airbag 104 undergoes adaptive deformation and contacts the left and right sides of the profile body 7. Figure 5 As shown, the airbag 104 covers the narrow space between the circular hole 71 and the outside of the profile body 7 and the conveyor belt of the conveyor 1, thereby improving the collection efficiency of debris.

Personnel familiar with the art can make various modifications or changes to the above embodiments without departing from the utility model concept of the present invention. Therefore, the protection scope of the present invention is not limited to the above embodiments, but should be the maximum scope of the innovative features mentioned in the claims.
