Description
Technical Field
[0001] The invention relates to the technical field of sandblasting equipment, in particular to sandblasting equipment for alloy steel forgings. Background Art
[0002] Alloy steel forging sandblasting equipment is a kind of equipment that uses compressed air as a power source to spray high abrasives onto the surface of the workpiece to achieve the purpose of cleaning, rust removal, and improving surface quality. These equipment are widely used in various industries, such as automobile manufacturing, ship repair, construction, etc., to clean rust and paint residues on the metal surface to improve the cleanliness and adhesion of the workpiece surface and prepare for subsequent painting or welding processes.
[0003] The nozzle inside the alloy steel forging sandblasting equipment is constantly swinging to sandblast the workpiece. However, when working on some alloy steel forgings with special shapes, due to the problem of the spray angle of the spray gun, the side of the alloy steel forging that is inclined or perpendicular to the conveyor belt cannot be hit by the abrasive at a good angle, resulting in uneven sandblasting on the surface of the alloy steel forging. This situation usually occurs by adding spray guns at different angles and coordinating the swing of the spray gun to achieve sandblasting on multiple planes of the alloy steel forging. Adding too many spray guns inside the alloy steel forging sandblasting equipment will first increase the difficulty of cleaning and maintenance costs. Secondly, too many spray guns will cause too many overlapping sandblasting areas, thereby increasing abrasive consumption. In addition, setting too many spray guns will also increase the power consumption of the alloy steel forging sandblasting equipment.
[0004] In view of the above problems, the prior art provides some solutions. For example, patent application number: CN202223234209.3 provides a uniform sandblasting equipment for high-precision metal surfaces, including a body, the bottom end of the body is fixedly connected to a support leg, the output end of the servo motor extends to the inside of the body and is fixedly connected to a working turntable through a coupling, and a sandblasting gun is fixedly connected to the middle position of the top of the body. This solution is to set multiple rows of spray guns on the top of the body, and each row of spray guns performs sandblasting on the surface of the alloy steel forging at different angles. In this solution, the side of the alloy steel forging that is inclined or perpendicular to the conveyor belt cannot be hit by the abrasive at a good angle, resulting in uneven sandblasting on the surface of the alloy steel forging. However, setting too many spray guns will first increase the difficulty of cleaning and maintenance costs. Secondly, too many spray guns will cause too many overlapping sandblasting areas, thereby increasing abrasive consumption, and setting too many spray guns will also increase the power consumption of the alloy steel forging sandblasting equipment. Summary of the invention
[0005] The object of the present invention is to provide a sandblasting treatment equipment for alloy steel forgings, so as to solve the problem that adding too many spray guns inside the sandblasting treatment equipment for alloy steel forgings firstly increases the cleaning difficulty and maintenance cost, and secondly too many spray guns will cause too many overlapping sandblasting areas, thereby increasing abrasive consumption, and setting too many spray guns will also increase the power consumption of the sandblasting treatment equipment for alloy steel forgings.
[0006] To achieve the above object, the present invention provides the following technical solutions:
[0007] A sandblasting treatment device for alloy steel forgings comprises a shell, a motor and a conveyor belt, wherein the motor is fixedly connected to the shell, a sandblasting chamber is arranged inside the shell, an output end of the motor extends to the inside of the sandblasting chamber, a moving component with a slider is also arranged on the shell, the slider is slidably connected to the shell, a rotating component is arranged on the slider, a rotating shaft is fixedly connected to the rotating component, a spray gun is adjustably and rotatably connected to the rotating shaft, the moving component is fixedly connected to the output end of the motor, when the motor is started, the moving component controls the slider to translate along the slide groove, when the slider moves to the ends of both ends of the slide groove, the rotating component controls the spray gun to rotate toward the conveyor belt direction.
[0008] It is easy to understand that the design connects the spray gun to the rotating shaft in an adjustable rotation manner, so that the alloy steel forging sandblasting equipment can adjust the angle of the spray gun according to the size and number of the alloy forgings before starting sandblasting, so that the abrasive sprayed by the spray gun can hit the surface of the alloy forging at a better angle. Therefore, this design not only improves the sandblasting effect of the alloy forgings, but also saves the consumption of abrasives. The design sets a moving component and a rotating component inside the alloy steel forging sandblasting equipment. The moving component controls the slider to move back and forth through the drive of the motor, so that the spray gun moves with the slider, and the rotating component controls the rotation. The rotation of the shaft is used to control the rotation of the spray gun. The cooperation between the two components enables the spray gun in the sandblasting chamber to move back and forth above the conveyor belt while changing its angle. This design can achieve that a single spray gun can completely cover the metal forgings at any position on the conveyor belt. At the same time, by adjusting the angle of the spray gun, the side of each metal forging can be effectively sandblasted. This design can reduce the number of spray guns inside the alloy steel forging sandblasting equipment, thereby facilitating the cleaning and maintenance of the interior of the sandblasting chamber, and further saving the consumption of abrasives and reducing the power consumption of the alloy steel forging sandblasting equipment.
[0009] The moving assembly includes a rocker arm, a moving groove is provided on the rocker arm, one end of the rocker arm is fixedly connected to the output end of the motor, the rotating shaft is slidably connected in the moving groove, the outer shell is provided with a slide groove, the slider is slidably connected in the slide groove, when the rotating shaft rotates, the angle between the spray gun and the slide groove after being adjusted to the maximum angle is θ, the width of the conveyor belt is X, the length of the slide groove is Y, the distance from the slide groove to the conveyor belt is Z, and Y=Z / tanθ.
[0010] It is easy to understand that the alloy steel forging sandblasting equipment is internally provided with a moving component, and the swing arm will swing back and forth under the drive of the motor output end, and the slider in the sliding groove will move back and forth in the sliding groove following the movement of the swing arm, and the rotating shaft will also move back and forth following the slider, and the spray gun fixedly connected to the rotating shaft will also move along with the rotating shaft. During the movement of the spray gun, the metal forgings on the conveyor belt will be sandblasted back and forth. This design increases the sandblasting area of the spray gun by designing the movement of the spray gun as a back and forth translation, and the limitation on the length of the slide groove enables the slider to drive the spray gun to move to the specified position to effectively sandblast the metal forgings on the edge of the conveyor belt, and also avoids the slide groove being too long and occupying too much space.
[0011] The rotating assembly includes a rotating head, an arc groove is provided on the slider, the rotating head is rotatably connected to the arc groove, the rotating shaft is fixedly connected to the rotating head, the slider is also provided with a rectangular groove 1, a protrusion is provided on the rotating head, a rotating opening is provided on the arc groove, the protrusion extends into the rectangular groove 1 through the rotating opening, a rectangular rod 1 is provided in the slide groove, the number of the rectangular rods 1 is 2, the two rectangular rods 1 are respectively fixedly connected to both sides of the slide groove, and the rectangular rod 1 contacts the protrusion through the rectangular groove 1.
[0012] It is easy to understand that the alloy steel forging sandblasting equipment is internally provided with a rotating assembly. Whenever the slider moves to the end of the slide groove, the rectangular rod 1 will contact and squeeze the protrusion in the rectangular groove 1, thereby causing the protrusion to drive the rotating head and the rotating shaft to rotate. At this time, the spray gun fixed on the rotating shaft will rotate along with the rotating shaft. At this time, the spray gun can sandblast the top and side surfaces of the metal forging at an inclined angle. This design enables the spray gun to rotate every time the slider moves to the end of the slide groove, thereby causing the top and side surfaces of the metal forging to be fully impacted by the abrasive to achieve a good surface treatment effect.
[0013] The slider is provided with a locking groove 1 on both sides, and a locking block is slidably connected inside the two locking grooves 1. The locking block is "L"-shaped, and the rotating head is provided with two locking grooves 2. A locking opening is also provided on the inner wall of the locking groove 1, and the locking opening connects the locking groove 1 with the locking groove 2. One end of the locking block extends into the locking groove 2 through the locking opening. A spring 1 is provided between the locking block and the inner wall of the locking groove 1. The slider is also provided with a rectangular groove 2, and an articulated groove is provided at one end of the locking block pointing upward. A control rod is hinged on the articulated groove, and the control rod extends into the rectangular groove 2. The control rod is close to One side of spring one is in contact with the inner wall of the hinge groove, a torsion spring is arranged between the control rod and the inner wall of the hinge groove, and rectangular rod two is also arranged on the slide groove, and the number of rectangular rod two is 2, and the two rectangular rods two are respectively fixedly connected on both sides of the slide groove, and the rectangular rod two is in contact with the control rod through the rectangular groove two, and the rectangular rod two includes a contact rod and an extrusion plate, and an extrusion groove is opened on the outer shell, and the contact rod is slidably connected in the extrusion groove, and spring two is arranged between the inner wall of the extrusion groove and the contact rod, and the rectangular rod two is in contact with the control rod through the rectangular groove two, and the extrusion plate is fixedly connected to the contact rod, and the extrusion plate is in contact with the slider.
[0014] It is easy to understand that the design sets two locking blocks inside the slider, and also sets rectangular rods 2 at both ends of the slide slot. Whenever the slider moves to the ends of both sides of the slide slot, the rectangular rod 2 on the slide slot will squeeze the control rod on one side of the slider to make the control rod rotate around the hinge, and the control rod on the other side of the slider will be pushed by the rectangular rod 2 because one side is pressed by the inner wall of the hinge slot, thereby driving the locking block to leave the locking slot 2 on the rotating head. When the rectangular rod 1 squeezes the protrusion to rotate the rotating head, the locking block on the other side of the slider will be moved into the locking slot 2 on the rotating head by the action of the spring 1, so that the rotating head cannot rotate, thereby avoiding the change of the nozzle angle due to the ejection of abrasive at the nozzle outlet after each angle adjustment, thereby improving the reliability of the sandblasting equipment for alloy steel forgings.
[0015] A plurality of rollers are respectively arranged on both sides of the bottom of the slider, and the rollers are rotatably connected to the slider. A chamfer is arranged on one edge of the roller which is in contact with the inner wall of the slide groove, and an inclined surface consistent with the inclination angle of the chamfer is arranged at the bottom of the slide groove. A connecting groove is also arranged at the bottom of the slide groove, and the connecting groove connects the inside of the slide groove with the outside of the shell.
[0016] It is easy to understand that the design converts the sliding friction between the original slider and the inner wall of the slide groove into rolling friction by designing a roller on the slider, thereby avoiding the abrasive ejected from the spray gun from bouncing into the slide groove and causing jamming during the operation of the alloy steel forging sandblasting equipment. Therefore, the design improves the reliability of the alloy steel forging sandblasting equipment. In addition, the design also sets the edge of one side where the roller fits the inner wall of the slide groove as a chamfer, and the bottom of the slide groove is provided with an inclined surface consistent with the inclination angle of the chamfer, and a connecting groove is also provided to connect the inside of the slide groove with the outside of the shell, so that the abrasive bounced into the slide groove will slide downward along the inclined surface and return to the sandblasting chamber through the connecting groove, thereby avoiding the abrasive accumulation inside the slide groove and affecting the operation of the alloy steel forging sandblasting equipment, and further improving the reliability of the alloy steel forging sandblasting equipment.
[0017] The slider is also provided with an extrusion block, which is slidably connected in the second rectangular groove. The bottom and two side surfaces of the extrusion block are both in contact with the inner wall of the second rectangular groove. Two grooves are symmetrically provided on the extrusion block. The control rod extends into the groove, and the control rod contacts the inner wall of the groove. The contact rod contacts the extrusion block.
[0018] It is easy to understand that the design has a sliding extrusion block on the rectangular groove 2. Whenever the slider moves to the ends of both sides of the slide groove, the rectangular rod 2 on the slide groove will push the extrusion block to make the extrusion block slide. When the extrusion block moves, the inner wall of the groove will contact the control rod and push the locking block through the control rod. The design pushes the locking block by setting the extrusion block and pushing the extrusion block through the rectangular rod 2. The extrusion block can completely cover the internal structure of the slider, thereby avoiding the abrasive from bouncing into the inside of the slider during the operation of the alloy steel forging sandblasting equipment and affecting the normal operation of the slider, thereby further improving the reliability of the alloy steel forging sandblasting equipment.
[0019] The distance between the two sides and the top surface of the slider and the inner wall of the slide groove is greater than 2 mm, and the distance between the swing rod and the inner wall of the sandblasting chamber is also greater than 2 mm.
[0020] It is easy to understand that when the alloy steel forging sandblasting equipment is sandblasting metal forgings, the abrasives used are mainly divided into three levels of coarse sand (0.6-2.0mm), medium sand (0.425-1.4mm), and fine sand (0.08-0.6mm) according to the size of the abrasive particles. It is known that the size of the abrasive particles used in the conventional alloy steel forging sandblasting equipment ranges from 0.08mm to 2.0mm. Therefore, by setting the distance between the two sides of the slider and the top surface and the inner wall of the slide groove, and between the rocker arm and the inner wall of the sandblasting chamber to be greater than 2mm, this setting can effectively prevent abrasive particles from being embedded and stuck in the gap between the slider and the inner wall of the slide groove and between the rocker arm and the inner wall of the sandblasting chamber, affecting the normal operation of the alloy steel forging sandblasting equipment, thereby improving the reliability of the alloy steel forging sandblasting equipment.
[0021] Compared with the prior art, the present invention has the following beneficial effects:
[0022] 1. The present invention provides a moving component inside the alloy steel forging sandblasting equipment. Under the drive of the motor output end, the swing arm will swing back and forth, the slider in the sliding groove will move back and forth in the sliding groove following the movement of the swing arm, the rotating shaft will also move back and forth following the slider, and the spray gun fixedly connected to the rotating shaft will also move along with the rotating shaft. During the movement of the spray gun, the metal forgings on the conveyor belt will be sandblasted back and forth. The design designs the movement of the spray gun to be a back and forth translation, thereby achieving that the sandblasting area of a single spray gun completely covers the metal forgings on the conveyor belt, reducing the power consumption of the equipment and saving the consumption of abrasives.
[0023] 2. The present invention provides a rotating assembly inside the alloy steel forging sandblasting equipment. This design enables the rectangular rod to contact and squeeze the protrusion in the rectangular groove whenever the slider moves to the end of the slide slot, thereby causing the protrusion to drive the rotating head and the spray gun on the rotating shaft to rotate, so that the top surface and the side surface of the metal forging can be fully impacted by the abrasive to achieve a good surface treatment effect. Therefore, the sandblasting angle of a single spray gun can effectively sandblast both sides of the metal forging on the conveyor belt, thereby improving the sandblasting effect and further reducing the power consumption of the equipment.
[0024] 3. The present invention arranges two locking blocks inside the slider and also arranges two rectangular rods at both ends of the slide slot. Whenever the slider moves to the ends of both sides of the slide slot, the control rod on the other side of the slider is pushed by the two rectangular rods, thereby driving the locking block to leave the two locking slots on the rotary head. When the rectangular rod one squeezes the protrusion to rotate the rotary head, the locking block on the other side of the slider is moved into the two locking slots by the action of the spring one, so that the rotary head cannot rotate, thereby avoiding the change of the nozzle angle due to the ejection of abrasive at the nozzle outlet after the nozzle rotates, and improving the reliability of the sandblasting equipment for alloy steel forgings.

Before the motor starts, the angle of the spray gun 32 is adjusted first, and the motor output end 4 drives the swing rod 33 to swing. The inner wall of the moving groove 34 on the swing rod 33 applies pressure to the rotating shaft 31, so that the rotating shaft 31 drives the slider 6 to move toward the end of the slide groove 11.
