Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing, and in particular to an automatic cutting device for small sheet metal parts. Background Technology

[0002] Sheet metalworking is a comprehensive cold working process for thin metal sheets, especially for ferrous metal products. It includes shearing, punching / cutting / combined cutting, bending, welding, riveting, etc. Its most significant characteristic is that the thickness of the same part is consistent. Products processed through sheet metal work are called sheet metal parts. The term "sheet metal part" generally varies across different industries and is often used in assembly contexts.

[0003] When processing sheet metal parts, they need to be cut to achieve the required shape. However, after cutting, the scraps and debris generated by the current cutting equipment fall to the ground or accumulate on the workbench. These scraps and debris need to be cleaned up again. If a small amount of the scrap is left connected to the sheet metal part during cutting, the scrap needs to be manually processed again, which is very inconvenient and reduces production efficiency. Therefore, an automatic cutting device for small sheet metal parts is proposed to address the above problems. Utility Model Content

[0004] In view of the above-mentioned problems in the prior art, the main purpose of this utility model is to provide an automatic cutting device for small sheet metal parts. When the cutting head cuts the sheet metal parts, the sheet metal scraps are attracted by an electromagnetic chuck. During the movement of the cutting head, the electromagnetic chuck is stationary relative to the sheet metal scraps and will not affect the cutting of the sheet metal parts.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an automatic sheet metal cutting device for small parts, including sheet metal cutting equipment, a cutting head, a transfer mechanism and a debris collection mechanism; The sheet metal cutting equipment is equipped with a cutting head for cutting sheet metal parts. A transfer mechanism is installed on the side of the cutting head, and a debris collection mechanism is provided at the bottom of the transfer mechanism for collecting the debris generated during cutting. The right side of the sheet metal cutting equipment is also equipped with a waste collection box for collecting scrap materials. The transfer mechanism includes a mounting base fixedly connected to the cutting head, and a motor and a rotatable lead screw are installed inside the mounting base. The lead screw is driven by the motor. A slider nut is fitted onto the lead screw, and the slider nut is threadedly connected to the lead screw. An electromagnetic chuck is fixedly connected to the bottom of the slider nut.

[0006] Furthermore, the outer side of the electromagnetic chuck is connected to external wiring.

[0007] The external wiring connects to the power cord of the external control equipment, and the electromagnetic chuck is used to pick up the cut scraps.

[0008] Furthermore, a groove is provided at the bottom of the mounting base, and the slider nut is slidably connected to the mounting base through the groove.

[0009] When processing sheet metal parts, they need to be cut to achieve the required shape. However, after the current cutting equipment completes the cutting, the sheet metal scraps separate from the sheet metal parts and fall directly, which is difficult to collect. At the same time, when a small amount of scraps are connected to the sheet metal parts after cutting, manual processing is required, which is very inconvenient. The technical solution of this application, when in use, is powered by an external power source. After the cutting head cuts the sheet metal parts, scraps will fall onto the worktable. At this time, the motor is started, which drives the lead screw to rotate. The lead screw drives the slider nut to move towards the scrap. Correspondingly, the electromagnetic chuck below the slider nut also moves towards the scrap until it reaches the position directly above the scrap, at which point it stops moving, making the electromagnetic chuck stationary relative to the scrap. The electromagnetic chuck is then activated to pick up the scrap. Then the motor is started again, driving the lead screw to rotate. The corresponding slider nut moves the electromagnetic chuck towards the waste bin until it moves above the waste bin and stops moving. Then the electromagnetic chuck is demagnetized and the scrap falls into the waste bin. This achieves centralized transfer of scraps to the waste bin for centralized collection and processing. The whole process is simple and efficient, and does not require operators to touch the sheet metal parts and scraps, effectively protecting the safety of operators.

[0010] Furthermore, the debris collection mechanism includes a fixed frame that is fixedly connected to the mounting base, an air suction device installed inside the fixed frame, and a filter plate that is fixedly connected to the fixed frame on one side of the air suction device. A collection box is also slidably connected inside the fixed frame.

[0011] The debris collection mechanism can collect small debris generated during the cutting process at any time, preventing these debris from remaining on the workbench and affecting the cutting of sheet metal parts, while also keeping the working environment clean.

[0012] Furthermore, the filter plate is inclined at a 45° angle to the horizontal direction.

[0013] The inclined filter plate can increase the contact area with debris, improve filtration efficiency, and prevent a large amount of debris from adsorbing onto the filter plate.

[0014] Furthermore, the fixing frame is located on one side of the cutting head below the cutting head, and the fixing frame is open on the side of the cutting head below the cutting head.

[0015] The suction device ensures that when the cutting head cuts the sheet metal parts, the debris generated can be drawn into the fixed frame and filtered by the filter plate. The collection frame can collect the debris that falls off the filter plate, ensuring a clean and tidy working environment.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. By setting up a transfer mechanism, when the cutting head cuts the sheet metal parts, the sheet metal scraps are attracted by the electromagnetic chuck. During the movement of the cutting head, its motor drives the lead screw to rotate, the lead screw drives the threaded sleeve to move, and the threaded sleeve drives the slider nut and the electromagnetic chuck to move, so that the electromagnetic chuck is stationary relative to the sheet metal scraps, ensuring the cutting quality. After the cutting is completed, the threaded sleeve drives the slider nut and the electromagnetic chuck to move, so that the scraps can be transferred to the top of the waste box and placed into the waste box for centralized collection and processing. 2. The suction device ensures that when the cutting head cuts the sheet metal parts, the debris generated can be drawn into the fixed frame and filtered by the filter plate. The collection frame can collect the debris that is blocked by the filter plate, ensuring a clean and tidy working environment. Attached Figure Description

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0020] An automatic sheet metal cutting device for small parts, such as Figs. 1-3As shown, it includes sheet metal cutting equipment 1, cutting head 2, sheet metal part 4, transfer mechanism 3 and debris collection mechanism 5; A cutting head 2 for cutting sheet metal parts 4 is installed above the sheet metal cutting equipment 1; The side of the cutting head 2 is equipped with a transfer mechanism 3 for centralized transfer of the cut scraps, and the bottom of the transfer mechanism 3 is also equipped with a debris collection mechanism 5 for centralized collection of the debris generated during cutting. A waste collection box 6 for collecting scrap materials is also installed on one side of the sheet metal cutting equipment 1; The transfer mechanism 3 includes a mounting base 301 that is fixedly connected to the cutting head 2. A motor 302 is installed inside the mounting base 301. A lead screw 303 is fixedly connected to the end of the drive shaft of the motor 302. The other end of the lead screw 303 is rotatably connected to the mounting base 301. The bottom of the mounting base 301 is fixedly connected to the debris collection mechanism 5; The lead screw 303 is helically connected to a threaded sleeve 304, the threaded sleeve 304 is fixedly connected to a slider nut 305, and the bottom of the slider nut 305 is fixedly connected to an electromagnetic chuck 306.

[0021] The electromagnetic chuck 306 is connected to an external wiring 307 on its outer side.

[0022] The bottom of the mounting base 301 is provided with a sliding groove 304, and the slider nut 305 is slidably connected to the mounting base 301 through the sliding groove 304.

[0023] In this technical solution, an external power supply is used. After the cutting head 2 cuts the sheet metal part 4, scrap pieces fall onto the worktable. At this time, the motor 302 is started, which drives the lead screw 303 to rotate. The lead screw 303 drives the slider nut 305 to move towards the scrap piece. Correspondingly, the electromagnetic chuck 306 below the slider nut 305 also moves towards the scrap piece until it reaches the position directly above the scrap piece and stops moving, so that the electromagnetic chuck 306 is stationary relative to the sheet metal scrap piece. At this time, the electromagnetic chuck 306 is activated to pick up the scrap piece. After the electromagnetic chuck 306 has completely picked up the scrap material, the motor 302 is restarted. The motor 302 drives the lead screw 303 to rotate in the opposite direction. The corresponding slider nut 305 drives the electromagnetic chuck 306 to move towards the scrap box 6 until the electromagnetic chuck 306 moves above the scrap box 6 and stops moving. Then, the electromagnetic chuck 306 is demagnetized and the scrap material is released to fall into the scrap box 6. This achieves centralized transfer of the scrap material into the scrap box 6 for centralized collection and processing. The whole process is simple and efficient, and does not require operators to touch the sheet metal parts 4 and the scrap material, which can effectively protect the safety of operators.

[0024] The other end of the external wiring 307 is connected to the electromagnetic chuck 306 device to control the normal adsorption and release action of the electromagnetic chuck 306. The cutting head 2, motor 302, and electromagnetic chuck 306 in this device are all controlled by an external controller. The operating principle and connection circuit of the device are existing technologies in this field, so they will not be described in detail.

[0025] The debris collection mechanism 5 includes a fixed frame 501 fixedly connected to the mounting base 301, an air suction device 502 installed inside the fixed frame 501, and a filter plate 503 fixedly connected to the fixed frame 501 on one side of the air suction device 502. A collection box 504 is also slidably connected inside the fixed frame 501.

[0026] The filter plate is tilted at a 45° angle to the horizontal.

[0027] The fixing frame 501 is located on one side of the cutting head below the cutting head 2, and the fixing frame 501 is open on the side facing the cutting head below the cutting head 2.

[0028] The suction device 502 ensures that when the cutting head 2 cuts the sheet metal part 4, the generated debris can be adsorbed into the fixed frame 501 and filtered by the filter plate 503. The collection frame 504 can collect the debris blocked by the filter plate 503, ensuring a clean and tidy working environment. The filter plate 503 is inclined, which increases the contact area between the filter plate 503 and the debris, and effectively blocks large debris, allowing these debris to fall into the collection frame 504 along its inclined direction. The debris can be processed normally by sliding the collection frame 504. One side of the fixed frame 501 is open to facilitate the entry of debris.

[0029] Finally, it should be noted that the above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
