Description

Technical Field

[0001] The utility model relates to the technical field of sheet metal processing, in particular to a positioning and cutting device for sheet metal processing. Background Art

[0002] Sheet metal processing is a process of machining metal materials into the desired shape and size through mechanical processing, which usually involves operations such as metal cutting, bending, stamping, and welding. Sheet metal cutting is an important part of the sheet metal processing process. When cutting metal plates, they are usually fixed to ensure cutting stability.

[0003] After searching, the Chinese patent "A positioning and cutting device for sheet metal processing" authorization announcement number "CN 217799349U" is set up by a servo motor to drive the rotation of the positive and negative threaded rods, so that the threaded sleeve drives the limit mechanism to move left and right, and adjusts the fixed spacing to facilitate the fixation of metal sheets of different sizes, thereby improving the scope of use of the device. By setting an L-shaped plate, a screw rod, a rotating handle and a limit plate, the metal sheet can be limited.

[0004] Although the above application can push the limit plate to fix the metal plate by rotating the screw rod, it is necessary to rotate the two screw rods separately to push the corresponding limit plate to move downward, which is relatively cumbersome. In addition, when rotating the screw rod to push the limit plate to fix the metal plate, the force of the limit plate pressing the metal plate can only be judged by experience, which can easily lead to a certain deviation in the force during fixation, thereby affecting the stability of the fixation.

[0005] Therefore, a positioning and cutting device for sheet metal processing is proposed to solve the above problems. Utility Model Content

[0006] The purpose of the present utility model is to provide a positioning and cutting device for sheet metal processing in order to solve the above-mentioned problems, which improves the problem that it is necessary to rotate two screw rods separately to push the corresponding limit plates to move downward, which is rather cumbersome. In addition, when the screw rods are rotated to push the limit plates to fix the metal plates, the force of the limit plates pressing the metal plates can only be judged by experience, which can easily lead to a certain deviation in the force during fixation, thereby affecting the stability of the fixation.

[0007] The top end face of said sliding arm is fixedly provided with a toothed connecting strip which is cooperatively connected with said toothed connecting gear.

[0008] Preferably, the fixing mechanism further comprises a plurality of circular tubes fixedly connected to the inner wall of the fixed plate, the bottom end of the circular tube being fixedly connected to a suction cup, a fixed cylinder being fixedly connected to one side of the movable frame, a second piston rod being slidably connected to the inner wall of the fixed cylinder, the top end of the second piston rod passing through the fixed cylinder, the bottom end of the fixed cylinder being connected to an air inlet pipe, a connecting pipe being connected between the circular tube and the air inlet pipe, and a circular plate being fixedly connected to the top end of the fixed cylinder. The plurality of suction cups adsorbing the surface of the metal plate is conducive to enhancing the stability of the metal plate fixation. At the same time, when the suction cups squeeze the metal plate, the squeezed gas enters the fixed cylinder through the connecting pipe and the air inlet pipe. Under the action of the second piston rod and the circular plate, it is conducive to enabling staff to more intuitively observe the fixing effect of the suction cup and the fixed plate on the metal plate.

[0009] Preferably, the bottom end of the first piston rod is fixedly connected to a first spring, and the other end of the first spring is fixedly connected to the inner bottom wall of the cylinder. When the device is in the initial state, the first spring exerts a certain pulling force on the first piston rod, thereby ensuring the stability of the device during operation.

[0010] Preferably, the top end of the second piston rod is fixedly connected to a second spring, and the other end of the second spring is fixedly connected to the top end of the fixing cylinder. When the device releases the fixation of the metal plate, the second spring is conducive to driving the second piston rod to return to its initial state.

[0011] Preferably, a one-way valve is provided on the surface of the air inlet pipe to prevent the gas from flowing back into the suction cup, thereby ensuring the stability of the suction cup adsorption.

[0012] Preferably, a sealing plug is provided at the top of the circular tube to prevent external air from entering the suction cup when the metal plate is fixed, and to facilitate the suction cup to release the adsorption of the metal plate by opening the sealing plug when the metal plate is released.

[0013] Preferably, a contact pad is fixedly connected to the bottom end of the suction cup, and the contact pad is a rubber component, which is conducive to sealing the suction cup and the surface of the metal plate, thereby ensuring the suction effect of the suction cup on the metal plate.

[0014] The beneficial effects of the utility model are:

[0015] 1. The setting of the fixing mechanism: rotating the bidirectional screw rod allows the two movable plates to limit the metal plate from both sides of the metal plate. At the same time, the extrusion plate squeezes the gas in the gas storage box so that the gas enters the two cylinders at the same time, which is conducive to the two first piston rods pushing the corresponding fixed plates to move downward at the same time to fix the metal plate from the top, and the fixed plate will drive multiple suction cups to adsorb the surface of the metal plate, which is conducive to strengthening the stability of the metal plate fixation. At the same time, when the suction cup squeezes the metal plate, the squeezed gas enters the fixed cylinder through the connecting pipe and the air inlet pipe. Under the action of the second piston rod and the circular plate, it is conducive to allowing the staff to more intuitively observe the fixing effect of the suction cup and the fixed plate on the metal plate, which is conducive to maintaining a constant clamping force on the metal plate, thereby ensuring the stability of the metal plate fixation;

[0016] 2. The setting of the contact pad is conducive to keeping the suction cup and the surface of the metal plate in a sealed state, ensuring the adsorption effect of the suction cup on the metal plate. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] When implementing: Figure 1-5 As shown, a positioning and cutting device for sheet metal processing includes: a base 1, a mobile frame 2 is slidably connected to the surface of the base 1, a cutting machine 3 is installed at the bottom end of the mobile frame 2, and a fixing mechanism 4 is provided at the top of the base 1; wherein the fixing mechanism 4 includes a bidirectional screw rod 41 rotatably connected to the base 1, and two mobile plates 42 are slidably connected to the top of the base 1, the lower end of the inner wall of the mobile plate 42 is bolted to the surface of the bidirectional screw rod 41, the top of the mobile plate 42 is fixedly connected to a cylinder 43, and one side of the base 1 is fixedly connected An air tank 44 is connected, and an extrusion plate 45 is slidably connected to the inner wall of the air tank 44. An electric push rod 46 is fixedly connected to one side of the air tank 44. One end of the electric push rod 46 passes through the air tank 44 and is fixedly connected to one side of the extrusion plate 45. A three-way pipe 47 is fixedly connected to the other side of the air tank 44. The other two ends of the three-way pipe 47 are respectively connected to the corresponding cylinder 43. A first piston rod 48 is slidably connected to the inner wall of the cylinder 43. One end of the first piston rod 48 passes through the cylinder 43 and is fixedly connected to the fixed plate 410. The other two ends of the three-way pipe 47 are configured as bellows. The air tank 44 is filled with gas.

[0025] The cutting machine 3 includes a motor and a cutting blade. The motor is connected to the movable frame 2. When the motor is started, the cutting blade is driven to rotate to cut the metal plate.

[0026] The inner walls of the two movable plates 42 are connected to the threads of the bidirectional screw rod 41 in opposite directions. Therefore, when the bidirectional screw rod 41 rotates, the two movable plates 42 are driven to move toward each other.

[0027] When fixing the metal plate, place the metal plate on the top of the base 1, and rotate the bidirectional screw rod 41 to drive the two movable plates 42 to move and approach each other. At this time, when the two movable plates 42 cannot move further, the two movable plates 42 will limit the metal plate from both sides.

[0028] like Figure 3 、 Figure 4 and Figure 5 As shown, the fixing mechanism 4 also includes a plurality of circular tubes 411 fixedly connected to the inner wall of the fixed plate 410, the bottom end of the circular tube 411 is fixedly connected to a suction cup 412, one side of the mobile frame 2 is fixedly connected to a fixed cylinder 413, the inner wall of the fixed cylinder 413 is slidably connected to a second piston rod 414, the top end of the second piston rod 414 passes through the fixed cylinder 413, the bottom end of the fixed cylinder 413 is connected to an air intake pipe 415, a connecting pipe 416 is connected between the circular tube 411 and the air intake pipe 415, and the top end of the fixed cylinder 413 is fixedly connected to a circular plate 417.

[0029] The air inlet pipe 415 is composed of an L-shaped pipe and a horizontal pipe, and the vertical portion of the L-shaped pipe is configured as a corrugated pipe.

[0030] When the two movable plates 42 limit the metal plate from both sides, the controller activates the electric push rod 46 to push the extrusion plate 45 to move and squeeze the gas in the gas storage box 44. The gas will enter the two cylinders 43 at the same time through the three-way pipe 47 and push the first piston rod 48 to move downward. At this time, the two first piston rods 48 will simultaneously push the corresponding fixed plate 410 to move downward and make the suction cup 412 at the bottom of the fixed plate 410 contact with the surface of the metal plate. At this time, the gas in the gas storage box 44 continues to be squeezed, so that the first piston rod 48 pushes the fixed plate 410 to move upward. When the second piston rod 414 moves downward, the interaction between the fixing plate 410 and the metal plate will squeeze the suction cup 412 to discharge the gas in the suction cup 412. The gas discharged from the multiple suction cups 412 will enter the air inlet pipe 415 at the same time through the circular tube 411 and the connecting tube 416, and enter the fixed cylinder 413 to push the second piston rod 414 to move upward. When the top end of the second piston rod 414 contacts the bottom end of the circular plate 417, a vacuum state is formed in the suction cup 412 and the top end of the metal steel plate is adsorbed. At this time, the electric push rod 46 is closed by the controller to complete the tight fixation of the metal steel plate.

[0031] like Figure 3 As shown, a first spring 49 is fixedly connected to the bottom end of the first piston rod 48, and the other end of the first spring 49 is fixedly connected to the inner bottom wall of the cylinder 43. When gas enters the cylinder 43 and pushes the first piston rod 48 downward, the first spring 49 is compressed. When the first piston rod 48 is no longer compressed by gas, the first spring 49 drives the first piston rod 48 and the fixed plate 410 to return to its original position.

[0032] like Figure 4 and Figure 5 As shown, a second spring 418 is fixedly connected to the top of the second piston rod 414, and the other end of the second spring 418 is fixedly connected to the top of the fixed cylinder 413. When gas enters the fixed cylinder 413 and presses the second piston rod 414, the second spring 418 is compressed. After the second piston rod 414 is no longer compressed by gas, the second spring 418 drives the second piston rod 414 to return to its original position.

[0033] like Figure 5 As shown, a one-way valve 419 is provided on the surface of the air intake pipe 415. The one-way valve 419 interacts with the air intake pipe 415 so that the air intake pipe 415 can only take in air in one direction.

[0034] like Figure 4 As shown, a sealing plug 420 is provided at the top of the circular tube 411. When the metal steel plate is fixed, the sealing plug 420 seals the circular tube 411. When the sealing plug 420 is opened, the external gas enters the suction cup 412 and the suction cup 412 can release the adsorption of the metal steel plate.

[0035] like Figure 4 As shown, the bottom end of the suction cup 412 is fixedly connected to a contact pad 421, which is a rubber component. When the suction cup 412 absorbs the metal steel plate, the surface of the contact pad 421 contacts the surface of the metal steel plate.

[0036] When the present invention is in use, when fixing the metal plate, the metal plate is placed on the top of the base 1, and the two-way screw rod 41 is rotated to drive the two movable plates 42 to approach each other and limit the position of the metal plate from both sides. After completing this operation, the electric push rod 46 is activated by the controller to push the extrusion plate 45 to move and squeeze the gas in the gas storage box 44. The gas will enter the two cylinders 43 at the same time through the three-way pipe 47 and push the first piston rod 48 to move downward. At this time, the two first piston rods 48 will simultaneously push the corresponding fixed plate 410 to move downward and make the suction cup 412 at the bottom end of the fixed plate 410 contact with the surface of the metal plate. At this time, the gas in the gas storage box 44 continues to be squeezed, so that the first piston rod 48 pushes the fixed plate 410 to move downward. The fixed plate 410 moves downward, and the interaction between the fixed plate 410 and the metal plate will squeeze the suction cup 412 to discharge the gas in the suction cup 412. The gas discharged from multiple suction cups 412 will enter the air inlet pipe 415 at the same time through the circular tube 411 and the connecting tube 416, and enter the fixed cylinder 413 to push the second piston rod 414 to move upward. When the top of the second piston rod 414 contacts the bottom of the circular plate 417, a vacuum state is formed in the suction cup 412 and the top of the metal steel plate is adsorbed. At this time, the electric push rod 46 is turned off by the controller, and the metal steel plate is tightly fixed. After the fixation is completed, the cutting machine 3 is driven to run, and the cutting machine 3 is driven by the movable frame 2 to move to cut the metal plate.

[0037] It should be noted that the electric push rod 46 and the motor in the above description are relatively mature devices in existing technology applications. The specific model can be selected according to actual needs. At the same time, the electric push rod 46 and the motor can be powered by a built-in power supply or by AC power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0038] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
