Description

Technical Field

[0001] The invention belongs to the technical field of plate processing, and in particular relates to a metal plate processing device. Background Art

[0002] Metal materials are one of the most commonly used materials in today's society. When we use metal materials, we need to process them, including drilling operations. Traditional drilling equipment often uses the method of pouring coolant to dissipate heat when drilling. This method of heat dissipation will cause a large amount of coolant to accumulate on the surface of the plate, forming a solution coating, which changes the heat dissipation action into multiple stages. The heat generated must first be transferred between liquid molecules to reach the liquid surface, and then be taken away by evaporation on the liquid surface, which greatly reduces the efficiency of heat dissipation and wastes coolant very seriously. At the same time, a large amount of coolant accumulation will adhere the waste generated by drilling together, which will cause trouble in cleaning the waste, and the accumulation of waste may scratch the surface of the plate or even damage the tool drill bit.

[0006] When punching, the fan is directly located on one side of the punching position. The airflow generated by the fan takes away part of the heat on the plate, and cooperates with the cooling water to improve the cooling effect of the plate. The waste chips generated by punching move into the collection chamber under the action of the airflow, and the waste chips are collected in the collection chamber to prevent the waste chips from staying on the surface of the plate and scratching the plate or the drilling tool.

[0007] Furthermore, the support assembly includes: a slider disposed in the guide rail; a support rod disposed on the slider; a suction cup disposed on the support rod; two guide rails are disposed on the base, and sliders are respectively disposed in the two guide rails, and the sliders in the two guide rails are connected by a first connecting rod.

[0008] The support assembly is used to support the plate to be processed, and the plate to be processed is moved to a processing position so as to process the plate.

[0009] Furthermore, a through cavity and a movable cavity are provided on the support rod. The through cavity passes through the movable cavity. The suction cup is communicated with the through cavity. A piston plate is provided in the movable cavity.

[0020] The collecting box is located opposite to the fan during sheet processing, and is used to collect the scattered waste chips to avoid the accumulation of waste chips on the sheets and processing equipment, thereby reducing the difficulty of cleaning the processing equipment and sheets in the later stage.

[0021] Furthermore, a second connecting shaft is provided on the side wall, and a second connecting groove corresponding to the second connecting shaft is provided on the inner wall of the collecting chamber; a protrusion is also provided in the collecting chamber, and a connecting rope is provided on the protrusion, one end of the connecting rope is fixedly connected to the bottom plate, and the connecting rope and the second connecting shaft are respectively provided on both sides of the bottom plate.

[0022] By using the connection rope, the bottom plate forms an inclined surface when flipping so as not to flip down completely, so as to discharge the waste chips in the material receiving box and process the waste chips uniformly.

[0024] The extension plate rests on the support plate so that the material receiving box is in the installation groove. The material receiving box only has its extended edge resting on the support plate and the top surface of the installation groove, so that the material receiving box can move up and down in the installation groove. When disassembling the material receiving box, the second push rod is pushed to move, and the second push rod drives the limit block to move. After the limit block moves out of the limit groove, the support plate is moved. After the support plate is away from the material receiving box, the extension plate loses its supporting force, so that the material receiving box can be directly taken out of the installation groove for cleaning.

[0056] The first connecting rod 110 is provided with a through groove, in which a movable block 117 is passed, a second connecting plate 116 is provided at the bottom of the movable block 117, the second connecting plate 116 is provided with an opening, and the opening is snapped into the first connecting groove; a second connecting rod 118 is provided on the inner wall of the through groove, a first movable groove is provided on the movable block 117, the second connecting rod 118 is passed through the first movable groove, a first return spring 119 is provided on the second connecting rod 118, and one end of the first return spring 119 rests against the inner wall of the first movable groove.

[0057] A first push rod 120 is provided on the base 101, and the first push rod 120 is located at the top of the second connecting plate 116. A second connecting block 1201 is provided on the first push rod 120. A second movable groove for the second connecting block 1201 to move is provided on the base 101. A second return spring 1202 is provided on the second connecting block 1201, and one end of the second return spring 1202 is fixedly connected to the bottom of the second movable groove. An electromagnet is provided at the bottom of the second movable groove, and a magnetic block is provided at the bottom of the second connecting block 1201.

[0058] After the plate is placed on the supporting assembly, the electromagnet is energized to attract the magnetic block to move downward, the first push rod 120 pushes the second connecting plate 116 to move downward, the second connecting plate 116 drives the extension rod 114 to move, and the first connecting plate 112 pulls the piston plate 111 to move, and the suction cup 109 is evacuated into a vacuum state, so that the plate is fixed on the suction cup 109; the first connecting plate 112 and the connecting spring 113 are arranged to ensure that the piston plate 111 can move to the limit state, thereby enhancing the adsorption force of the suction cup 109 on the plate; after the plate processing is completed, the electromagnet is powered off to reset the piston plate 111, and the plate can be directly removed, so that the plate can be quickly unloaded.

[0059] The first fixed block 105 is provided with a plurality of mounting rings 121, the mounting ring 121 is provided with a ring groove 1211 communicating with the cavity, a movable ring 122 is provided in the ring groove 1211, a plurality of paddles 1221 are provided on the movable ring 122, the paddles 1221 are located in the ring groove 1211, a third connecting rod is also provided on the movable ring 122, a first connecting shaft 124 is provided on the third connecting rod, and a fan 123 is provided on the first connecting shaft 124; all the first connecting shafts 124 on the first fixed block 105 are connected together by a transmission belt 125, and a motor for driving the transmission belt 125 to rotate is provided on the first fixed block 105 to provide power for the fan 123.

[0060] After the first fixed block 105 and the second fixed block 106 are against the plate, the motor drives the fan 123 to rotate. When the fan 123 rotates, it drives the movable ring 122 to rotate. The paddle 1221 rotates in the annular groove 1211 to stir the cooling water in the annular groove 1211. The cooling water in the annular groove 1211 enters the cavity, and the cooling water in the cavity enters the annular groove 1211, so that the cooling water in the cavity is in a flowing state, and the heat transferred to the first fixed block 105 is quickly taken away; at the same time, because the airflow passes through the movable ring 122, the ventilation volume in the movable ring 122 is increased, and the amount of cooling water in the annular groove 1211 is small. Under the action of the airflow, the cooling water in the annular groove 1211 quickly dissipates heat, so that the cooling water in the cavity is always at room temperature, effectively ensuring the cooling effect of the cooling water on the plate.

[0061] A plurality of through holes are provided on the side wall of the collecting chamber so that air flow can pass through the collecting chamber. A bottom plate 128 is provided at the bottom of the collecting chamber. A mounting groove is provided on the bottom plate 128. A material receiving box 126 is passed through the mounting groove.

The connecting rope 130 0 one end is fixedly connected to the bottom plate 128, the connecting rope 130 and the second connecting shaft 1281 are respectively arranged on both sides of the bottom plate 128; the connecting rope 130 is connected to the end of the bottom plate that is not connected to the collecting chamber. Since the length of the connecting rope is limited, when the bottom plate is tilted after the second fixing block is raised, the flip angle of the drooping end thereof is fixed, and the bottom plate will not be flipped to a vertical state, so that the bottom plate forms an inclined surface with a fixed angle after the second fixing block is raised, and the angle is preferably an acute angle less than 40°.

[0063] A support plate 127 is provided in the mounting groove, an extension plate 1271 is provided on the support plate 127, a third movable groove is provided on the support plate 127, a limit block 131 is provided in the third movable groove, a limit groove corresponding to the limit block 131 is provided on the inner wall of the mounting groove, a fourth movable groove is provided on the extension plate 1271, a second push rod 132 is provided in the fourth movable groove, the second push rod 132 is connected to the limit block 131 by a fourth connecting rod 133, a third return spring 134 is provided on the second push rod 132, and one end of the third return spring 134 rests on the inner wall of the fourth movable groove.

[0064] The extended edge of the top of the material receiving box 126 abuts against the top surface of the mounting groove of the support plate 127, and the side wall of the other side of the material receiving box abuts against the inner wall of the mounting groove, and the cooperation setting of the extended edge 1261 and the support plate 127 ensures that the material receiving box 126 is in the mounting groove and does not fall out of the mounting groove; because the material receiving box 126 only has the extended edge 1261 abutting against the support plate 127 and the top surface of the mounting groove to provide support for the material receiving box, the bottom surface of the material receiving box 126 can move upward in the mounting groove after contacting the plate, and after the material receiving box 126 is separated from the plate, the material receiving box 126 moves downward in the mounting groove under the action of gravity until the extended plate abuts against the support plate 127 and the top surface of the mounting groove again; when the second fixed block 106 abuts against the plate, the material receiving box 126 abuts against the plate and moves toward the top of the mounting groove, and the material receiving box 126 enters the collection chamber, and the waste chips blown into the collection chamber by the fan 123 are blocked On the side wall of the material receiving box 126; after the second cylinder drives the second fixed block 106 to rise, the material receiving box 126 enters the installation groove under the action of gravity, and the end of the bottom plate 128 connected to the connecting rope 130 turns downward under the action of gravity, and the bottom plate 128 rotates around the second connecting shaft 1281 so that the bottom plate 128 forms an inclined surface, and the waste chips on the bottom plate 128 all slide into the material receiving box 126 and collect the waste chips. The baffle 1262 blocks the sliding waste chips to prevent the waste chips from falling directly out of the installation groove; when disassembling the material receiving box 126, the second push rod 132 is pushed to move, and the second push rod 132 drives the limit block 131 to move. After the limit block 131 moves out of the limit groove, the support plate 127 is moved. After the support plate 127 is away from the material receiving box 126, the extension plate 1271 loses its supporting force, so that the material receiving box 126 can be directly taken out of the installation groove for cleaning.
