Abstract
Description
Technical Field
[0001] This utility model relates to the field of hydraulic press technology, and in particular to an automatic cleaning device for the lower crossbeam and moving worktable of a hydraulic press. Background Technology
[0002] In industrial production, the moving worktable and lower crossbeam are core components of various automated equipment (such as CNC machine tools and hydraulic presses). Their operational stability and cleanliness directly affect the overall processing accuracy, operating efficiency, and service life of the equipment. However, in traditional equipment designs, cleaning the contact surfaces between the moving worktable and the lower crossbeam often relies on "manual cleaning after machine shutdown" or "timed mechanical cleaning," which cannot be synchronized with the equipment's operating process and results in significant efficiency shortcomings.
[0003] If manual cleaning is used, the machine must be stopped during production breaks, and operators must use brushes, air guns, and other tools to clean the upper surface of the lower crossbeam and the lower surface of the moving worktable. Each cleaning session typically takes several minutes. In high-paced production scenarios (such as assembly lines and batch processing workshops), frequent downtime for cleaning significantly reduces effective production time, leading to a decrease in overall equipment utilization and increased production costs. There is also a risk of delays in scheduled cleaning: although some equipment is equipped with timed mechanical cleaning devices (such as the lower crossbeam brush), the cleaning frequency is fixed and cannot be dynamically adjusted according to the actual accumulation of debris. If the cleaning interval is too long, excessive accumulation of debris can easily occur, leading to equipment malfunctions.
[0004] Traditional cleaning processes lack targeted collection design for debris, resulting in debris (such as metal shavings and small parts) being scattered around the equipment after cleaning. This debris not only increases the burden of cleaning the workshop floor but may also cause operators to slip and fall, or be caught in moving parts of the equipment, leading to mechanical safety accidents and posing safety hazards to the production site.
[0005] To address this, this utility model proposes an automatic cleaning device for the lower crossbeam and the moving worktable of a hydraulic press. This device automatically cleans and removes all foreign objects from the moving worktable before it performs a closing action, ensuring that there are no foreign objects between the contact surfaces of the lower plane of the moving worktable and the upper plane of the lower crossbeam, and also ensuring their flatness. Summary of the Invention
[0006] The purpose of this utility model is to solve the problems existing in the prior art by proposing an automatic cleaning device for the lower crossbeam and moving worktable of a hydraulic press.
[0007] To achieve the above objectives, the present invention adopts the following technical solution: An automatic cleaning device for the lower crossbeam and movable worktable of a hydraulic press includes a lower crossbeam and a movable worktable that reciprocates on the upper plane of the lower crossbeam, comprising: The first cleaning device is fixedly installed on the side of the lower crossbeam. The first cleaning device includes a scraper, the cleaning surface of which faces the bottom surface of the movable worktable. A height adjustment device is provided at the lower end of the scraper, which is used to adjust the height of the scraper. The second cleaning device is fixedly installed on the side of the mobile workbench. The second cleaning device includes a nylon brush assembly and an air blowing assembly. The bristle end of the nylon brush assembly forms an adaptive contact with the lower plane of the mobile workbench. The air blowing assembly includes a pipe with multiple air blowing holes arranged on the pipe. The air blowing holes are directed towards the cleaning area of the nylon brush assembly. When the mobile workbench moves into the lower crossbeam along a preset trajectory, the scraper of the first cleaning device slides in contact with the lower plane of the mobile workbench, while the nylon brush assembly of the second cleaning device contacts the upper plane of the lower crossbeam, and the air blowing hole simultaneously blows airflow into the cleaning area on the upper plane of the lower crossbeam.
[0008] Furthermore, the air blowing assembly also includes a high-pressure air source device and an airflow control valve. The high-pressure air source device is connected to the air blowing hole through a pipe, the length of which is adapted to the length of the lower crossbeam. The airflow control valve is used to adjust the gas pressure of the air blowing hole.
[0009] Furthermore, the nylon brush assembly includes at least two nylon brushes, with a nylon brush shaft passing through the middle of each nylon brush. The two ends of the nylon brush shaft that are close to each other are connected by a coupling, which is rotatably connected to a coupling seat. The two ends of the nylon brush shaft that are far from each other are respectively fixed through the side plates of the movable worktable. A motor is provided on the outside of the movable worktable, and the output shaft of the motor is connected to the nylon brush shaft.
[0010] Furthermore, the height adjustment device includes a mounting plate, which is fixedly connected to the side of the lower crossbeam; vertical guide rails are symmetrically arranged at both ends of the mounting plate, and sliders are slidably fitted on the guide rails; the sliders are fixedly connected to a clamping plate, an elastic element is connected to the bottom of the clamping plate, a scraper is connected to the upper end of the elastic element, and a cylinder is connected below the clamping plate, with the cylinder barrel fixedly connected to the side of the lower crossbeam through a fixing block.
[0011] Furthermore, the first cleaning device and the second cleaning device are respectively provided with debris collection troughs below them.
[0012] Furthermore, the scraper is made of an elastic, wear-resistant material.
[0013] Compared with existing technologies, the automatic cleaning device for the lower crossbeam and moving worktable of a hydraulic press provided by this utility model has the following advantages: 1. This system integrates efficient air blowing and nylon brush cleaning, automatically removing foreign objects to a safe area. It minimizes equipment downtime, ensuring production line continuity and high-efficiency cycle time. Air blowing effectively removes light dust, debris, and non-adhesive particles, while the nylon brush handles sticky, heavy, and stubborn foreign objects. Compared to single-method cleaning, this combined cleaning mode significantly improves adaptability and cleaning efficiency, ensuring maximum cleaning results. 2. The combination design of "nylon brush + air hole" can not only thoroughly clean the debris on the upper surface of the lower crossbeam, but also guide the debris to the preset debris collection trough through the directional airflow of the air hole, so as to prevent the debris from being blown up and spread; at the same time, the scraper of the first cleaning device can scrape the debris on the lower surface of the moving workbench directly to the collection area, realizing "cleaning and collection simultaneously". 3. Synchronous cleaning does not take up working time and improves equipment operating efficiency. When the moving worktable moves into the lower crossbeam, there is no need to start the cleaning program separately. The scraper of the second cleaning device will automatically scrape away the debris on the lower plate of the moving worktable as the moving worktable moves. At the same time, the nylon brush and nozzle of the second cleaning device will also start synchronously to clean the upper surface of the lower crossbeam. The entire cleaning process is completely integrated into the normal operation of the equipment without additional time consumption. This ensures the continuity of production and avoids the interference of debris accumulation on equipment operation, significantly improving the overall operating efficiency of the equipment.

[0017] Example 1:
[0018] Reference Figures 1-5 An automatic cleaning device for the lower crossbeam and moving worktable of a hydraulic press includes a lower crossbeam 1, a moving worktable 3 that reciprocates on the upper plane of the lower crossbeam 1, and further includes: The first cleaning device 2 is fixedly installed on the side of the lower crossbeam 1. The first cleaning device 2 includes a scraper, and the cleaning surface of the scraper 25 faces the bottom surface of the movable worktable 3. The first cleaning device 2 is installed on the side of the lower crossbeam 1 near the external stop point of the movable worktable 3. The second cleaning device 4 is fixedly installed on the side of the movable workbench 3. The second cleaning device 4 includes a nylon brush assembly and an air blowing assembly. The bristle end of the nylon brush assembly forms an adaptive contact with the lower plane of the movable workbench 3. The air blowing assembly includes a pipe 421 with multiple air blowing holes arranged on the pipe 421. The air blowing holes are directed towards the cleaning area of the nylon brush assembly. The second cleaning device 4 is installed on the side of the movable workbench 3 near the lower crossbeam 1. When the mobile workbench 3 moves into the lower crossbeam 1 along a preset trajectory, the scraper 25 of the first cleaning device 2 slides in contact with the lower plane of the mobile workbench 3, and at the same time, the nylon brush assembly of the second cleaning device 4 contacts the upper plane of the lower crossbeam 1, and the air blowing hole blows airflow out of the cleaning area on the upper plane of the lower crossbeam 1 simultaneously. This structural design is used to clean the upper surface of the lower crossbeam 1 of the hydraulic press and the lower surface of the movable worktable 3 reciprocating inside the hydraulic press. The lower crossbeam 1 is fixed to the bottom of the hydraulic press. The reciprocating movement of the movable worktable 3 can be controlled by the external control system of the hydraulic press. Limit sensors are installed on the lower crossbeam 1 to restrict the position of the movable worktable 3. Displacement sensors are installed at the external stop points of the movable worktable 3. The displacement sensors can sense the position and movement status of the movable worktable 3. When the movable worktable 3 moves into the hydraulic press, the first cleaning device 2 and the second cleaning device 4 can clean the lower surface of the movable worktable 3 and the upper surface of the lower crossbeam 1, respectively. The first cleaning device 2 and the second cleaning device 4 are electrically connected to the control system.
[0019] In another embodiment, the first cleaning device 2 and the second cleaning device 4 can be installed as needed. The lower crossbeam 1 or the movable worktable 3 may only have the first cleaning device 2 installed, or only have the second cleaning device 4 installed. Alternatively, the second cleaning device 4 may be installed on the side of the lower crossbeam 1, and the first cleaning device 2 may be installed on the side of the movable worktable 3.
[0020] Example 2:
[0021] like Figure 3 As shown, the air blowing assembly also includes a high-pressure air source device and an airflow control valve. The high-pressure air source is connected to the air blowing hole through a pipe 421. The length of the pipe 421 is adapted to the length direction of the lower crossbeam 1. The airflow control valve is used to adjust the gas pressure of the air blowing hole.
[0022] A high-pressure air source device is arranged outside the hydraulic press to provide the high-pressure gas required for blowing, typically 0.3-0.8 MPa. This serves as the air source for the entire blowing assembly. The high-pressure gas passes through pipe 421 and is then ejected through the blowing holes, forming a directional airflow that directly acts on the cleaning area of the lower crossbeam 1. The number of blowing holes is determined according to the width of the lower crossbeam, and the blowing holes are evenly distributed along the circumference of pipe 421. Circular air holes are preferred because they are easy to manufacture and provide uniform airflow. The diameter of the blowing holes is 1-3 mm, and the air outlet direction forms a 30°-45° angle with the cleaning area of the nylon brush 411, effectively blowing away debris without pushing it into the equipment.
[0023] The airflow control valve can precisely adjust the gas pressure of the air outlet to adapt to different types of debris, such as low pressure for light dust and high pressure for metal shavings.
[0024] The air blowing assembly also includes an electromagnetic reversing valve to control the start and stop timing of the air blowing assembly, ensuring that air blowing only occurs when the moving worktable 3 moves in. It can be linked with a limit sensor mounted on the lower crossbeam 1 and a displacement sensor located at the external stop point of the moving worktable 3. When the displacement sensor detects that the moving worktable 3 has just entered the initial area of the lower crossbeam 1, it immediately sends a signal to the control system, triggering the air blowing assembly to start, opening the electromagnetic reversing valve, and allowing high-pressure gas to blow away dust and metal debris from the air source, preventing debris from getting stuck. When the moving worktable 3 moves into position, the limit sensor detects it and sends a position signal to the control system. The control system then stops the nylon brush assembly and the air blowing assembly of the second cleaning device 4, preventing unnecessary energy waste.
[0025] Example 3:
[0026] like Figure 1 and Figure 3 As shown, the nylon brush assembly includes nylon brushes 411, and there are at least two nylon brushes 411. A nylon brush shaft passes through the middle of the nylon brush 411. The two ends of the nylon brush shaft that are close to each other are connected by a coupling 412. The coupling 412 is rotatably connected to a coupling seat. The two ends of the nylon brush shaft that are far from each other are respectively fixed through the two side plates of the movable worktable 3. A motor 413 is provided on the outside of the movable worktable 3. The output shaft of the motor 413 is connected to the nylon brush shaft.
[0027] In this embodiment, the coupling seat is fixed to the movable worktable 3 near the lower crossbeam 1 by bolts. The ends of the two nylon shafts that are close to each other are connected by a coupling 412. The coupling 412 is existing technology. The coupling 412 can stably transmit the rotational torque of the right nylon brush shaft to the left side to achieve power transmission. Due to installation errors or deformation during operation, the two nylon brush shafts may have radial or axial displacement. The elastic element of the coupling 412 can absorb these deviations through its own slight movement or deformation, avoiding damage to the nylon brush shafts and bearings due to forced alignment. Compared with rigid connections, the coupling 412 allows for a certain degree of alignment error during installation of the two nylon brush shafts, simplifying the assembly process.
[0028] Similarly, under the control of the control system, the motor 413 rotates, which drives the nylon brush shaft to rotate. The nylon brush shaft then drives the nylon brush 411 to rotate. Through the joint cleaning of the nylon brush 411 and the air hole, foreign objects, impurities and residual liquids on the upper surface of the lower crossbeam 1 can be cleaned.
[0029] Example 4:
[0030] like Figure 2 , Figure 4 and Figure 5As shown, the height adjustment device also includes a mounting plate 21, which is fixedly connected to the side of the lower crossbeam 1 by bolts; vertical guide rails 22 are symmetrically arranged at both ends of the mounting plate 21, and sliders 23 are slidably fitted on the guide rails 22; the sliders 23 are fixedly connected to a clamping plate 24, an elastic element is connected to the bottom of the clamping plate 24, a scraper 25 is connected to the upper end of the elastic element, and a cylinder 26 is connected to the lower part of the clamping plate 24. The cylinder barrel of the cylinder 26 is fixedly connected to the side of the lower crossbeam 1 by a fixing block 27; for example, the cylinder 26 is a small linear cylinder, and the scraper 25 is made of elastic wear-resistant material. For example, the edge of the scraper 25 may be provided with a rounded corner transition structure.
[0031] For example, the mounting plate 21 is adapted to the length of the scraper 25, and the upper and lower edges of the mounting plate 21 are rounded to prevent sharp edges from scratching operators or snagging debris. The guide rail 22 ensures that the slider 23 can only slide in the vertical direction without lateral movement, providing precise guidance for the scraper 25. The guide rail 22 and the slider 23 can be added as needed during implementation.
[0032] When the height of the first device 2 needs to be adjusted, the height of the scraper 25 is adjusted by extending the output end of the cylinder 26. The cylinder 26 is linked with the displacement sensor of the moving worktable 3. When the moving worktable 3 begins to move into the hydraulic press, the displacement sensor sends a signal, and the control system controls the extension end of the cylinder 26 to lift the clamping plate 24. The slider 23 guides the clamping plate 24 synchronously, and the clamping plate 24 lifts the scraper 25 synchronously, so that the bottom surface of the moving worktable 3 can be scraped. The scraper 25 is lifted by the output end of the cylinder 26. In this embodiment, the elastic element is a spring. When the spring is compressed, the upper end of the scraper 25 always maintains the contact pressure with the lower surface of the moving worktable 3 without gap, so as to scrape away foreign objects on the lower surface of the moving worktable 3.
[0033] As the moving worktable 3 continues to move in, the scraper 25 slides relative to the lower surface of the moving worktable 3, scraping away the hydraulic sludge, metal shavings and dust attached to the lower surface of the moving worktable 3.
[0034] When the movable worktable 3 is moved into place, the lower surface of the movable worktable 3 disengages from the scraper 25, the spring returns to its natural state, the extension end of the cylinder 26 retracts, and the scraper 25 moves down accordingly, ensuring that a gap is formed between the scraper 25 and the lower surface of the movable worktable 3 when the movable worktable 3 is withdrawn, thus avoiding additional wear caused by friction between the movable worktable 3 and the scraper 25.
[0035] like Figure 1As shown, in order to collect foreign objects and impurities on the lower crossbeam 1 and the movable worktable 3, the first cleaning device 2 and the second cleaning device 4 are respectively provided with debris collection troughs 5 below them. Debris scraped off by the scraper 25 from the movable worktable 3 falls into the debris collection trough 5 below the scraper 25 under gravity. Foreign objects cleaned by the nylon brush assembly and the air blowing assembly fall into the debris collection trough 5 on the other side of the lower crossbeam 1. The debris collection trough 5 serves the purpose of centrally collecting the debris after cleaning, avoiding secondary pollution.
[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
