Description

Technical Field

[0001] This invention relates to an automated cutting device, belonging to the technical field of arc cutting equipment. Background Technology

[0002] Automated arc cutting equipment is a processing device that uses the heat of an electric arc between a metal electrode and the workpiece to locally melt the workpiece, and then uses airflow or other methods to remove the molten slag for cutting or grooving. Automated arc cutting equipment mainly consists of a power supply, a control box, a cutting torch, and oxygen pipelines. The power supply provides the electrical energy required for the arc, the control box controls the cutting process, the cutting torch is the key component for generating the arc and supplying oxygen, and the oxygen pipeline provides oxygen for the cutting process.

[0003] Existing automated arc cutting equipment typically involves placing the sheet metal on a cutting platform, with the control box manipulating the torch to move and cut according to the input program. If the cut workpiece is smaller than the distance between two adjacent support plates of the cutting platform, it will fall directly through the platform to the ground, requiring the operator to sweep it out with a long-handled tool. If the cut workpiece is larger than the distance between the two adjacent support plates, it will fall onto the cutting platform, requiring the operator to climb up and retrieve it. Therefore, regardless of the method, retrieving the workpiece is extremely inconvenient for the operator, severely impacting the efficiency of sheet metal cutting. Furthermore, the freshly cut workpiece is at a high temperature, posing a significant safety hazard when handling it at close range. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by the present invention is to provide an automated cutting device that can place the cut workpiece in the workpiece storage area without the need for operators to retrieve the workpiece from above or below the cutting platform, thereby improving the efficiency of plate cutting and eliminating safety hazards during workpiece retrieval.

The bottom of the guide covers is provided with an inclined guide groove. The end of the guide groove is located above the lower receiving tray of the receiving cart. The guide covers are used to guide the smaller cut workpieces into the lower receiving tray. An inverted V-shaped dividing plate is provided between two adjacent guide covers on the cutting platform. The V-shaped dividing plate can divert the workpieces falling directly above it to the guide covers on both sides to prevent the workpieces from falling between the two guide covers.

[0007] Preferably, the crossbeam assembly includes a crossbeam, with a longitudinal slide fixedly connected below the crossbeam. The longitudinal slide is slidably connected to the cutting platform via a guide rail slider mechanism. A longitudinal motor is installed on the longitudinal slide, and a gear is sleeved on the output shaft of the longitudinal motor. The gear meshes with a rack fixed on the cutting platform. The side of the crossbeam closest to the feeding station protrudes from the cutting platform, thereby enabling the material handling assembly to move to the feeding station.

A longitudinal motor 32 is installed on the longitudinal slide block 33, and a gear is sleeved on the output shaft of the longitudinal motor 32. The gear meshes with a rack fixed on the cutting platform 1. The side of the crossbeam 31 near the material feeding station protrudes from the cutting platform 1, thereby enabling the material picking assembly 6 to move to the material feeding station.

[0040] The cutting torch assembly 2 is slidably connected to the crossbeam 31 via a guide rail slider mechanism. The cutting torch assembly 2 includes a cutting torch horizontal support 22, on which a cutting torch horizontal motor 23 is fixed.

The material handling fixture mounting plate 64 is connected to the material handling horizontal support 63 via a screw transmission mechanism. A material handling lifting motor 61 is fixed to the top of the material handling horizontal support 63. The material handling lifting motor 61 can drive the screw transmission mechanism to move, thereby driving the material handling fixture mounting plate 64 to move up and down. A material handling fixture 7 is fixed on the material handling fixture mounting plate 64.

[0042] The material handling fixture 7 includes a fixture connecting seat 71, with four sliding frames 77 fixedly connected below the fixture connecting seat 71. The sliding frames 77 are evenly distributed around the circumference. The sliding frames 77 are L-shaped and hollow. Vertical sliding blocks 73 are slidably arranged in the vertical frame of the sliding frame 77, and horizontal sliding blocks 76 are slidably arranged in the horizontal frame of the sliding frame 77. Both sides of the vertical sliding block 73 and the horizontal sliding block 76 are provided with detachable side wings. The side wings of the vertical sliding block 73 and the side wings of the horizontal sliding block 76 are hinged by a connecting rod 74. An electromagnet 761 is installed below the horizontal sliding block 76, which can attract the workpiece. The top of the vertical sliding block 73 is elastically connected to the bottom of the fixture connecting seat 71 by a spring A731.

[0043] An electric cylinder 72 is fixed on the fixture connecting seat 71. A docking cylinder mounting part 78 is fixed to the first end of the electric cylinder rod. A docking cylinder 79 is fixed around the docking cylinder mounting part 78. The docking cylinder 79 corresponds one-to-one with the sliding frame 77. The vertical sliding block 73 is provided with a docking hole 732. The docking hole 732 is adapted to the cylinder rod of the docking cylinder 79. When the cylinder rod of the docking cylinder 79 is extended, it can be inserted into the docking hole 732 to complete docking with the vertical sliding block 73.

[0044] The sliding frame 77 has vertical limiting grooves 773 on both sides that are adapted to the vertical sliding block 73, and the two side wings of the vertical sliding block 73 are movably disposed in the vertical limiting grooves 773; the sliding frame 77 also has horizontal limiting grooves 774 on both sides that are adapted to the horizontal sliding block 76, and the two side wings of the horizontal sliding block 76 are movably disposed in the horizontal limiting grooves 774; the bottom surface of the sliding frame 77 has an electromagnet clearance groove 775, and the back surface of the sliding frame 77 has a cylinder rod clearance groove 772; the horizontal frame end of the sliding frame 77 is detachably connected to a sealing plate 771 to facilitate the installation and removal of the sliding block.

[0045] A striking assembly 75 is installed directly below the docking cylinder mounting component 78. The striking assembly 75 can strike small workpieces that are adhered to the plate or stuck between the support plate 12, causing them to fall below the cutting platform 1. The striking assembly 75 includes a striking fixing component 751, which is fixedly connected to each sliding frame 77. The striking fixing component 751 can fix the striking assembly 75 as a whole and also support the bottom of each sliding frame 77, increasing its connection strength. A striking rod 752 is inserted through the striking fixing component 751, and a spring B753 is sleeved on the striking rod 752. The spring B753 is located between the top plate of the striking rod 752 and the striking fixing component 751. Guide limiting rods 754 are installed on both sides of the striking rod 752. The bottom of the guide limiting rod 754 is provided with a limiting baffle. The guide limiting rods 754 are used to guide and limit the striking rod 752.

[0046] A control box 8 and an operation panel 4 are installed on the side of the cutting platform 1 away from the material feeding station. The control box 8 and the operation panel 4 are electrically connected. The control box 8 controls the operation of each motor, electric cylinder, air cylinder, and cutting torch.

[0047] The working process of this invention is as follows:

[0048] 1. The cutting torch assembly 2 moves to directly above the part of the plate to be cut, and the cutting torch lifting motor 21 drives the cutting torch 24 to descend and cut the plate; the moving direction of the crossbeam 31 is defined as the length direction of the workpiece, and the moving direction of the cutting torch assembly 2 is defined as the width direction of the workpiece; after the cutting is completed, the cutting torch assembly 2 moves to the standby position of the end plate of the crossbeam 31.

[0049] 2. If the length of the cut workpiece is less than the distance between two adjacent support plates, the workpiece will pass through the support plate 12, fall to the guide cover 11, and then slide down along the inclined guide groove 111 into the lower receiving tray of the receiving cart 5.

[0050] If the workpiece is stuck or jammed with the sheet metal at this time, the material handling component 6 can be moved above the workpiece, keeping the cylinder rods of each docking cylinder 79 in the retracted state. The electric cylinder 72 is activated, causing the bottom of the docking cylinder mounting part 78 to press the striking rod 752. The striking rod 752 moves down and strikes the workpiece, completely separating the workpiece from the sheet metal. After the striking is completed, the electric cylinder 72 drives the docking cylinder mounting part 78 back to the initial position. At this time, the center of the cylinder rod of the docking cylinder 79 is directly opposite the docking hole 732 of the vertical sliding block 73.

[0051] 3. If the length of the cut workpiece is greater than the distance between two adjacent support plates, the workpiece will remain on support plate 12; at this time, control the material handling component 6 to move above the center of the workpiece, and adjust the opening and closing degree of each electromagnet 761 according to the actual size of the workpiece:

[0052] 3.1 If the length and width of the workpiece are both greater than the maximum length and width spacing after the electromagnet 761 is opened and closed, the cylinder rods of each docking cylinder 79 around the perimeter will extend and dock with the corresponding vertical sliding block 73. Then, the electric cylinder 72 will move, causing the docking cylinder mounting part 78 to move down, which will drive the vertical sliding block 73 to move down against the tension of the spring A731. The vertical sliding block 73 will push the horizontal sliding block 76 to move outward through the connecting rod 74, and the electromagnet 761 will open and close to the maximum length and width spacing. After that, the material picking and lifting motor 61 will move, the material picking fixture 7 will descend, and after the electromagnet 761 contacts the workpiece, it will be energized to attract the workpiece. Then, the workpiece will be transferred to the upper receiving tray of the receiving cart 5.

[0053] 3.2 If the length of the workpiece is greater than the maximum length gap after the electromagnet 761 is opened and closed, and the width of the workpiece is less than the maximum width gap after the electromagnet 761 is opened and closed, the cylinder rods of the two docking cylinders 79 along the length of the workpiece extend and dock with the corresponding vertical sliding block 73. Then, the electric cylinder 72 opens and closes the two electromagnets 761 along the length to the maximum length gap, while the gap between the two electromagnets 761 along the width of the workpiece remains unchanged, so as to adsorb and transfer the workpiece.

[0054] 3.3 If the width of the workpiece is greater than the maximum width spacing after the electromagnet 761 is opened and closed, and the length of the workpiece is less than the maximum length spacing after the electromagnet 761 is opened and closed, the cylinder rods of the two docking cylinders 79 along the width direction of the workpiece extend and dock with the corresponding vertical sliding block 73. Then, the electric cylinder 72 opens and closes the two electromagnets 761 in the width direction to the maximum width spacing, while the spacing of the two electromagnets 761 along the length direction of the workpiece remains unchanged, so as to adsorb and transfer the workpiece.

[0055] The above-mentioned workpiece handling method ensures that the workpiece handling fixture 7 can stably adsorb the workpiece and prevent it from falling off or shaking when moving the workpiece. After the workpiece is transferred, the electric cylinder 72 drives the docking cylinder mounting part 78 to reset, and at the same time, the cylinder rod of the docking cylinder 79 retracts. Under the action of the spring A731, the vertical sliding block 73 also springs back to reset. At this time, the cylinder rod of the docking cylinder 79 is aligned with the docking hole 732 for the next docking.
