Description

Technical Field

[0001] This utility model relates to the field of debris handling technology, specifically a debris handling device for pressing steel plate forming process. Background Technology

[0002] During the forming process of pressed steel sheets, operations such as cutting and drilling generate a large amount of debris. These scraps and debris generated during the processing are a type of scrap metal. This type of material has a loose structure, large volume, light weight, and is inconvenient to collect and transport. Directly recycling it to the furnace results in high losses and low yield. Therefore, it is necessary to compress these debris.

[0003] According to a search report from a novelty search agency, announcement number CN222036292U discloses a steel plate processing debris pressing and processing device, which includes a base plate. A base is connected to one side of the upper end of the base plate, and a box body is connected to the upper end of the base. Both sides of the box body have discharge ports, and one end of the discharge port has a box door. The box door is rotatably connected to the box body, and one end of the box door is connected to a handle. A pressing mechanism is provided inside the box body. Through the setting of the pressing mechanism, the gears on the upper and lower pull sides are driven by a dual-shaft motor to rotate, so that the gears on the other side mesh with it, thereby making the gears on the left and right sides rotate synchronously. Under the drive of the crankshaft, the first connecting rod and the second connecting rod respectively drive the first fixed plate and the second fixed plate to move away from each other or move closer to each other, so that the compression space between the T-shaped plate and the C-shaped plate compresses the debris, or releases space to facilitate the placement of debris. Through this structure, the debris is compressed, effectively reducing the volume and facilitating transportation.

[0004] The above-disclosed steel plate processing chip pressing and processing device involves pouring the chips generated during processing into a box, using a hydraulic cylinder to drive the top plate to seal the upper part, then using a dual-axis motor to drive the pressing mechanism to compress the chips, and finally having personnel open the box door to remove the compressed chip blocks, thus achieving compression processing. However, the following shortcomings exist in its use.

[0005] The process requires multiple steps of manual operation, including loading, horizontal compression, and unloading. It cannot automatically perform sealing and post-compression material discharge during compression, making the operation cumbersome, inconvenient, and lacking in automation. Furthermore, manually removing material from the inside is inconvenient. In view of this, this application proposes a chip handling device for pressing steel plate forming to solve the above-mentioned problems. Utility Model Content

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] like Figures 1 to 3 As shown in this embodiment, a chip handling device for forming and processing pressed steel plates includes:

[0030] The base 1 has an inclined surface on its top left side. The top of the base 1 is rectangular and fixedly connected with four support legs 101. The front side of the base 1 has a weight reduction through hole.

[0031] The rectangular box 2 is inclined and has an opening on the right side. The rectangular box 2 is fixedly connected to the top of the four support legs 101.

[0032] The feed hopper 202 is connected and fixed to the top of the rectangular box 2;

[0033] The PLC controller 201 is fixedly installed on the bottom right side of the rectangular box 2;

[0034] The self-closing feed type chip pressure control and compression assembly is installed inside the rectangular box 2 and electrically connected to the PLC controller 201. The self-closing feed type chip pressure control and compression assembly is used to compress the chips after the pressing of the steel plate, and detects the compression force and transmits the pressure value to the PLC controller 201. The PLC controller 201 controls it to reset when the compression force is reached according to the preset pressure value, so as to accurately control the pressure and compress the chips and automatically reset.

[0035] The unsealing and discharge assembly is installed between the bottom left side of the rectangular box 2 and the base 1, and is electrically connected to the PLC controller 201; the unsealing and discharge assembly is used to automatically unseale and discharge materials under the control of the PLC controller 201 after the pressure compression process.

[0036] Specifically, the self-sealing feed debris control and compression assembly includes a pressure plate 302 slidably connected between the front inner wall, rear inner wall, and bottom inner wall of a rectangular box 2. A baffle 306 is fixedly connected to the top of the pressure plate 302 and slides in contact with the top inner wall of the rectangular box 2. The top of the baffle 306 has a discharge hole 307 vertically aligned and communicating with the feed hopper 202. The left side of the baffle 306 slides out of the rectangular box 2. A rectangular through-hole is provided on the left inner wall of the rectangular box 2, and the inner wall of the rectangular through-hole slides against the outer side of the baffle 306, allowing the baffle 306 to pass through and providing lateral sliding guidance. A support is fixedly installed between the front and rear inner walls of the rectangular box 2. An electric hydraulic cylinder 301 is fixedly installed on the left side of the support 3. A pressure sensor 303 is fixedly connected between the extended end of the electric hydraulic cylinder 301 and the right side of the pressure plate 302. A tactile switch 308 with its actuating end in contact with the bottom right side of the pressure plate 302 is fixedly installed on the bottom inner wall of the rectangular box 2. The tactile switch 308, the electric hydraulic cylinder 301 and the pressure sensor 303 are all electrically connected to the PLC controller 201. Two horizontal guide tubes 304 are fixedly connected on the left side of the support 3. Horizontal guide rods 305 are slidably sleeved inside the horizontal guide tubes 304. The left ends of the two horizontal guide rods 305 are fixedly connected to the right side of the pressure plate 302, which serves to guide the pressure plate 302 laterally.

[0037] The pressure plate 302, baffle 306, discharge hole 307, support 3, electric hydraulic cylinder 301, and pressure sensor 303 are configured to work together. The PLC controller 201 pre-sets the pressure value for the reverse start and reset of the electric hydraulic cylinder 301. When the electric hydraulic cylinder 301 is started in the forward direction, causing it to drive the pressure plate 302 to move to the left via the pressure sensor 303, the pressure plate 302 drives the baffle 306 to move to the left. The baffle 306 then drives the discharge hole 307 to the left, offsetting it from the feed hopper 202 and blocking the feed hopper 202 to stop further feeding. As the pressure plate 302 moves to the left, it compresses the debris. The pressure sensor 303 monitors this in real time. The electric hydraulic cylinder 301 detects the compressive force applied and transmits it to the PLC controller 201. When the pressure value is reached, the PLC controller 201 controls the electric hydraulic cylinder 301 to start and reset in reverse, causing it to drive the pressure plate 302 and the baffle 306 to move back to the right to reset. The pressure plate 302, which moves back to the right, presses and actuates the tactile switch 308. When the tactile switch 308 is actuated, it transmits a corresponding signal to the PLC controller 201. At this time, the PLC controller 201 controls the electric hydraulic cylinder 301 to automatically shut down, thereby achieving controlled pressure compression of the debris and temporarily blocking the feed hopper 202 during compression and automatically resetting after compression.

[0038] Furthermore, the unsealing and discharging assembly includes a rectangular discharge hole 4 located on the bottom left side of the rectangular housing 2. A stop gate 401 is rotatably installed between the front and rear inner walls of the rectangular discharge hole 4. Both sides of the stop gate 401 are designed with arc-shaped structures. Circular grooves are provided on the front right and rear right sides of the stop gate 401, and bearings are fixedly fitted within these grooves. Pins are welded and fixed to the front and rear inner walls of the rectangular discharge hole 4. The inner ring of the bearing is fixedly fitted to the outer side of the corresponding pin. The pins and bearings enable the rotational installation of the stop gate 401. An inclined electric telescopic rod 402 is hinged between the bottom of the stop gate 401 and the top of the base 1. The electric telescopic rod 402 is electrically connected to the PLC controller 201. The electric telescopic rod 402, the rectangular discharge hole 4, and the stop gate 401 work together to pre- First, the PLC controller 201 is pre-set to control the electric telescopic rod 402 to start in reverse. This pressure value is the same as the pressure value of the controlled compression mentioned above. It is also pre-set to control the electric telescopic rod 402 to start in the forward direction and reset when it receives the corresponding signal transmitted by the tactile switch 308. When the pressure value received by the PLC controller 201 during compression reaches the preset value, it controls the electric telescopic rod 402 to start in reverse, causing it to drive the stop gate 401 to rotate downward and open, thus unsealing the rectangular discharge hole 4. At this time, the compressed debris falls downward and is discharged through the rectangular discharge hole 4. When resetting after compression, when the PLC controller 201 receives the corresponding signal transmitted by the tactile switch 308, it controls the electric telescopic rod 402 to start in the forward direction and reset, causing it to drive the stop gate 401 to rotate upward and reset, thus sealing the rectangular discharge hole 4.

[0039] The usage method of this embodiment is as follows: When using the chip processing device for pressing steel plates, the steel plate processing chips that need to be compressed are poured into the feed hopper 202. The chips enter the rectangular box 2 through the discharge hole 307. With its inclined setting, it is convenient for the chips to slide to the left after entering to allow subsequent materials to continue to enter. The PLC controller 201 is pre-set with the pressure values ​​for controlling the reverse start and reset of the electric hydraulic cylinder 301 and the reverse start of the electric telescopic rod 402. The pressure values ​​of the two are the same. It is also pre-set to control the electric telescopic rod 402 to start and reset in the forward direction when the corresponding signal transmitted by the tactile switch 308 is received. After the chips are added, they need to be compressed. During compression processing, when the forward-starting electric hydraulic cylinder 301 drives the pressure plate 302 to move to the left via the pressure sensor 303, the pressure plate 302 drives the two horizontal guide rods 305 to slide to the left within their respective horizontal guide tubes 304. The pressure plate 302 drives the baffle 306 to move to the left, causing the discharge hole 307 to shift to the left and offset from the feed hopper 202, thus blocking the feed hopper 202 and stopping further feeding. As the pressure plate 302 moves to the left, it compresses the debris. The pressure sensor 303 detects the compressive force applied by the electric hydraulic cylinder 301 in real time and transmits the pressure value to the PLC controller 201. When the preset value is reached, the PLC controller 201 controls the electric hydraulic cylinder 302 to move to the left. The hydraulic cylinder 301 reverses and resets, controlling the electric telescopic rod 402 to reverse as well. During this reverse reset, the pressure sensor 303 drives the pressure plate 302 and baffle 306 to move back to the right. The electric telescopic rod 402 drives the gate 401 to rotate downwards and open, unblocking the rectangular discharge hole 4. The compressed debris then falls through the rectangular discharge hole 4 and is discharged. After the pressure plate 302 moves back to the right, it presses and actuates the tactile switch 308. When the tactile switch 308 is actuated, it transmits a corresponding signal to the PLC controller 201. At this time, the PLC controller 201 controls the hydraulic cylinder 301 to automatically... The system automatically closes and controls the electric telescopic rod 402 to start and reset in the forward direction. The electric telescopic rod 402 drives the gate 401 to rotate upward and reset, sealing the rectangular discharge hole 4. This achieves the effect of automatically sealing the upper feeding position during compression and automatically unsealing the lower part for material discharge after compression. It also achieves the effect of automatically sealing the discharge position when the upper pressure plate 302 resets after discharge. This eliminates the need for personnel to perform separate operations at three locations and remove the compressed debris. The operation is simple, time-saving, and labor-saving, improving work efficiency and automation. The method of directly discharging the compressed debris makes it more convenient for personnel to use and reduces the difficulty of personnel retrieving materials from the inside.

[0040] The PLC controller 201, electric hydraulic cylinder 301, electric telescopic rod 402, pressure sensor 303, and tactile switch 308 in this utility model are well-known to those skilled in the art and belong to conventional methods or common knowledge. Those skilled in the art can arbitrarily select and match them according to their needs or convenience. In addition, the PLC controller 201 receives the pressure value transmitted by the pressure sensor 303 and controls the electric hydraulic cylinder 301 to reset and the electric telescopic rod 402 to start in reverse when the preset value is reached. It also controls the electric hydraulic cylinder 301 to close and the electric telescopic rod 402 to reset when the corresponding signal transmitted by the tactile switch 308 is received. These are basic programming controller parameter setting control methods well-known to those skilled in the art and belong to conventional methods or common knowledge of CNC programmers. They will not be described in detail here.
