Description

Technical Field

[0001] The present application belongs to the technical field of hydraulic press equipment, and in particular, relates to a hydraulic press safety protection mechanism. Background Art

[0002] A hydraulic press is a machine that uses liquid as the working medium and is made according to Pascal's principle to transfer energy to achieve various processes. A hydraulic press is generally composed of three parts: the machine (host), the power system, and the hydraulic control system. Hydraulic presses are classified into valve hydraulic presses, liquid hydraulic presses, and engineering hydraulic presses.

[0003] The existing Chinese patent with publication number CN212171382U discloses a hydraulic press with a safety protection mechanism, including a driving mechanism, a hydraulic platform and a hydraulic pump. The hydraulic platform is installed at the bottom end of the driving mechanism, and the output end of the hydraulic pump is connected to the driving mechanism through an infusion pipe. The limit groove and the limit block cooperate with each other. The hydraulic press is provided with an observation porthole on the surface of the safety baffle, and sliders are provided on both sides of the safety baffle, and the sliders and the slide rails cooperate with each other.

[0004] Although the above-mentioned hydraulic press with a safety protection mechanism can reduce the defective rate of pre-processed parts, and the safety baffle blocks the flying chips during the working process and improves the safety protection effect, after the hydraulic press finishes working, debris will remain on the surface of the workbench, which needs to be manually cleaned by the staff. At the same time, the workbench requires more manual assistance. When the hydraulic press malfunctions or the staff misoperates, the hydraulic block may suddenly slide down and press the staff's hands, posing certain safety hazards. Utility Model Content

[0005] The purpose of this application is to provide a hydraulic press safety protection mechanism to address the above-mentioned technical problems, which can automatically clean up debris on the surface of the workbench, prevent the hydraulic block from suddenly sliding down, prevent the hands of workers from being crushed, and has high safety.

[0006] The present application provides a hydraulic press safety protection mechanism, including a hydraulic press body, wherein the hydraulic press body includes:

[0007] A cleaning device, including an electromagnetic scraper and a vibrating assembly;

[0008] A buffer device, a first screw rod, a first protection block and a second protection block;

[0009] Protective devices;

[0010] A base connected to the second protection block;

[0011] Workbench;

[0012] A hydraulic block, which cooperates with the first screw rod;

[0013] Among them, the cleaning device is installed on the workbench, the electromagnetic scraper is connected to the vibration component, the first protective block is connected to the first screw rod, the first protective block is matched with the second protective block, and the first screw rod and the base are rotatably connected through the matching of the first protective block and the second protective block.

[0014] In the technical solution, a cleaning device with an electromagnetic scraper and a vibration component is arranged on the hydraulic press body. After the hydraulic press is finished working, debris remains on the surface of the workbench. The cleaning device controls the electromagnetic scraper to move along the surface of the workbench. The electromagnetic scraper is energized when cleaning the workbench, making it magnetic, which is convenient for cleaning metal debris. After the cleaning is completed, the electromagnetic scraper is powered off and loses its magnetism, and vibrates through the vibration component connected to it, thereby removing the metal debris on the electromagnetic scraper. A buffer device with a first screw rod, a first protective block and a second protective block is also arranged on the hydraulic press body. The first screw rod cooperates with the hydraulic block, and the hydraulic block is on the hydraulic press body. When lifting, it can drive the first screw rod rotatably connected to the base to rotate. When the hydraulic press is abnormal or the operator operates it incorrectly, the hydraulic block suddenly drops at a faster speed, which can drive the first screw rod to rotate quickly. The first screw rod and the base are connected to rotate through the cooperation of the first protective block and the second protective block. When the first screw rod rotates too fast, the second protective block can limit the first protective block to prevent the first screw rod from continuing to rotate, and at the same time prevent the hydraulic block connected to the first screw rod from continuing to descend. Combined with the above-mentioned technical features, the mechanism can automatically clean up debris on the surface of the workbench and avoid the sudden decline of the hydraulic block, reducing many safety hazards and having a higher level of safety.

[0015] Furthermore, the cleaning device comprises:

[0016] A first bracket including a contact;

[0017] A second bracket is rotatably connected to the first bracket and is rotatably connected to the electromagnetic scraper strip;

[0018] First motor;

[0019] A second screw rod connected to the first motor;

[0020] Wherein, the workbench is provided with a guide rail, the first bracket cooperates with the guide rail, the guide rail cooperates with the contact, the first bracket cooperates with the second screw rod, and the contact is connected with the electromagnetic scraper strip.

[0021] In the present technical scheme, a first motor with a second screw is arranged on the cleaning device, an electromagnetic scraper is rotatably connected to the second bracket, the second bracket is rotatably connected to the first bracket with contacts, the first bracket cooperates with the second screw, and the contacts cooperate with the guide rails on the workbench. When cleaning, the first motor is started, the first motor drives the second screw to rotate, and the second screw drives the first bracket to move on the guide rail. At the same time, the contacts on the first bracket are in contact with the guide rails, and the electromagnetic scraper is energized with magnetism to facilitate cleaning of metal debris. After cleaning, the first bracket has been placed at the other end of the workbench. At this time, the contacts on the first bracket are disconnected from the guide rails, the electromagnetic scraper is powered off and loses its magnetism, and shakes off the attached debris through the vibration component. After that, the first motor reverses to reset the cleaning device, so that the equipment has the function of automatic cleaning, and the cleaning device can clean the debris in time to keep the workbench flat. Processing pre-processed parts on a flat workbench can reduce the defective rate and improve the processing quality.

[0022] Furthermore, the vibration component comprises:

[0023] A second motor, which is mounted on the first bracket;

[0024] Rotating shafts, including oblique shafts;

[0025] Wherein, the oblique shaft is rotationally connected to the electromagnetic scraper strip, and the rotating shaft is connected to the second motor.

[0026] In the present technical solution, a second motor with a rotating shaft is provided on the vibration component, and the rotating shaft is connected to the oblique shaft, and the oblique shaft is rotationally connected to the electromagnetic scraper strip. When the vibration component is working, the second motor installed on the first bracket is started, and the second motor drives the rotating shaft and the oblique shaft to rotate. Since the electromagnetic scraper strip is rotationally connected to the second bracket, and the second bracket is rotationally connected to the first bracket, the rotating oblique shaft drives the electromagnetic scraper strip to reciprocate in the second bracket, and at the same time drives the second bracket to reciprocate in the first bracket, so that the electromagnetic scraper strip can fully shake off debris after reciprocating rotation in two directions, thereby extending the working life of the electromagnetic scraper strip.

[0027] Furthermore, the buffer device comprises:

[0028] Spring, including push block;

[0029] A claw, which is rotatably connected to the first protection block;

[0030] a limiting groove mounted on the second protection block;

[0031] A rotation speed sensor connected to the first screw rod;

[0032] A buzzer is connected to the speed sensor;

[0033] Wherein, the clamping claw cooperates with the limiting groove, and the spring and the clamping claw are installed on the first protection block.

[0034] In the present technical scheme, a spring and a claw with a push block are installed on the first protective block, and a limiting groove is installed on the second protective block. The claw cooperates with the limiting groove. When the hydraulic press body works normally, the first screw rotates at a low speed, and the claw is subjected to a small inertial centrifugal force. The claw is tightened by the spring so that the first protective block can rotate in the second protective block. When the hydraulic press body is abnormal or the hydraulic block suddenly drops due to misoperation by the staff, the first screw rotates at a high speed, and the claw is subjected to a large inertial centrifugal force. The claw opens through the spring and cooperates with the limiting groove to fix the first protective block and the second protective block, thereby stopping the first screw, that is, stopping the hydraulic block from descending. A speed sensor is also connected to the first screw, and the speed sensor is connected to a buzzer. When the speed sensor detects that the speed of the first screw is too fast, it sends a signal to the buzzer to make the buzzer alarm to remind the staff.

[0035] Furthermore, the protective device comprises:

[0036] protective panels, including viewing windows;

[0037] A chain connected to the guard plate;

[0038] A transmission block cooperates with the chain;

[0039] A counterweight block connected to the chain;

[0040] Wherein, the first screw rod is provided with a helical gear, and the helical gear cooperates with the transmission block.

[0041] In the present technical scheme, a protective plate connected to a chain is provided on the protective device, the other end of the chain is connected to the counterweight block, and the chain cooperates with the transmission block, and the transmission block cooperates with the bevel gear on the first screw rod. When the hydraulic block is pressed down, it drives the first screw rod to rotate, and the bevel gear on the first screw rod drives the transmission block to rotate. The chain drives the protective plate to rise through the transmission between it and the transmission block, and the counterweight block drops accordingly, so that the protective plate can block the flying chips generated when the hydraulic press is working, so as to improve the safety protection effect, and the staff can observe the working condition of the hydraulic press through the observation window on the protective plate. After the work is completed, the hydraulic block rises and drives the first screw rod to reverse, and the bevel gear on the first screw rod drives the transmission block to reverse, and the chain drives the protective plate to descend through the transmission between it and the transmission block, and the counterweight block rises accordingly, so that the staff can perform manual assisted operations on the workbench.

[0042] Further, the electromagnetic scraper strip is provided with bristles;

[0043] Wherein, the hydraulic press body is provided with a chip collection box.

[0044] In the present technical solution, bristles are provided on the electromagnetic scraper bar so that the electromagnetic scraper bar can clean non-metallic debris through the bristles, thereby expanding the application scope of the equipment. The hydraulic press body is also provided with a chip collection box. When the vibration component is working, the debris shaken off the electromagnetic scraper bar can be placed in the chip collection box to avoid affecting the working environment around the hydraulic press body.

[0045] The beneficial effects of this application are:

[0046] 1. The cleaning device controls the electromagnetic scraper to move along the workbench. The electromagnetic scraper is energized and magnetic during cleaning, which facilitates cleaning. The electromagnetic scraper loses its magnetism after cleaning and starts the vibration component to shake off metal debris. When the hydraulic block is abnormal, it descends faster, driving the first screw rod matched with it to rotate at high speed, and triggering the first protection block to fix it with the second protection block to prevent the first screw rod from continuing to rotate, that is, to prevent the hydraulic block from descending, thereby reducing safety hazards and improving safety of this mechanism.

[0047] 2. When cleaning, start the first motor to drive the first bracket to move on the guide rail, the contact on the first bracket contacts the guide rail, the electromagnetic scraper is energized and magnetic, after cleaning, the contact is disconnected, the electromagnetic scraper is powered off and loses its magnetism, and the vibration component is started to shake off the debris. The cleaning device keeps the workbench flat to improve the processing quality. When vibrating, the second motor drives the inclined axis to rotate, and the inclined axis drives the electromagnetic scraper to reciprocate in the second bracket, and at the same time drives the second bracket to reciprocate in the first bracket, so that the electromagnetic scraper can fully shake off the debris through reciprocating rotation in two directions.

[0048] 3. When the hydraulic block is working normally, the first screw rotates at a low speed, the inertial centrifugal force on the claw is small, and the claw is tightened by the spring. When the hydraulic block drops suddenly due to abnormality, the first screw rotates at a high speed, the inertial centrifugal force on the claw is large, the claw is opened by the spring and cooperates with the limiting groove to fix the first protection block and the second protection block, so that the first screw stops rotating to prevent the hydraulic block from falling. When the speed sensor detects that the speed of the first screw is too fast, the buzzer is controlled to alarm to remind the staff.

[0049] 4. When the hydraulic block is pressed down, it drives the first screw to rotate. The first screw drives the protective plate to rise and the counterweight block to fall, so that the protective plate can block flying chips to improve the safety protection effect, and the staff can observe the working conditions through the observation window. After the work is completed, the hydraulic block rises and drives the first screw to reverse. The first screw drives the protective plate to fall and the counterweight block to rise, which is convenient for the staff to perform manual auxiliary operations. BRIEF DESCRIPTION OF THE DRAWINGS

It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0057] The following provides a detailed description of the embodiments of the present application through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0058] Embodiment 1:

[0059] like Figure 1-4 As shown, the embodiment of the present application provides a hydraulic press safety protection mechanism, including a hydraulic press body 100, wherein the hydraulic press body 100 includes:

[0060] The cleaning device 200 includes an electromagnetic scraper 210 and a vibration assembly 220;

[0061] A buffer device 300, a first screw rod 310, a first protection block 320 and a second protection block 330;

[0062] Protective device 400;

[0063] The base 110 is connected to the second protection block 330;

[0064] Workbench 120;

[0065] The hydraulic block 130 cooperates with the first screw rod 310;

[0066] Among them, the cleaning device 200 is installed on the workbench 120, the electromagnetic scraper 210 is connected to the vibration assembly 220, the first protective block 320 is connected to the first screw rod 310, the first protective block 320 is matched with the second protective block 330, and the first screw rod 310 is connected to the base 110 through the matching rotation of the first protective block 320 and the second protective block 330.

[0067] By arranging a cleaning device 200 with an electromagnetic scraper 210 and a vibration component 220 on the hydraulic press body 100, after the hydraulic press is finished working, debris remains on the surface of the workbench 120, and the cleaning device 200 controls the electromagnetic scraper 210 to move along the surface of the workbench 120. When the electromagnetic scraper 210 is powered on when cleaning the workbench 120, it is magnetic, which is convenient for cleaning metal debris. After the cleaning is completed, the electromagnetic scraper 210 is powered off and loses its magnetism, and vibrates through the vibration component 220 connected thereto, thereby removing the metal debris on the electromagnetic scraper 210. A buffer device 300 with a first screw rod 310, a first protective block 320 and a second protective block 330 is also arranged on the hydraulic press body 100. The first screw rod 310 cooperates with the hydraulic block 130, and the hydraulic block 130 is in the hydraulic press. When the main body 100 is raised or lowered, it can drive the first screw rod 310 rotatably connected to the base 110 to rotate. When the hydraulic press is abnormal or the operator misoperates, the hydraulic block 130 suddenly drops at a faster speed, which can drive the first screw rod 310 to rotate quickly. The first screw rod 310 and the base 110 are connected to each other through the cooperation of the first protective block 320 and the second protective block 330. When the first screw rod 310 rotates too fast, the second protective block 330 can limit the first protective block 320 to prevent the first screw rod 310 from continuing to rotate, and at the same time prevent the hydraulic block 130 connected to the first screw rod 310 from continuing to descend. Combined with the above-mentioned technical features, the mechanism can automatically clean up the debris on the surface of the workbench 120 and avoid the hydraulic block 130 from suddenly sliding down, reducing many safety hazards and having higher safety.

[0068] Furthermore, the cleaning device 200 includes:

[0069] A first bracket 230 including a contact 231;

[0070] The second bracket 240 is rotatably connected to the first bracket 230 and is rotatably connected to the electromagnetic scraper strip 210;

[0071] A first motor 250;

[0072] A second screw rod 260 connected to the first motor 250;

[0073] The workbench 120 is provided with a guide rail 121 , the first bracket 230 cooperates with the guide rail 121 , the guide rail 121 cooperates with the contact 231 , the first bracket 230 cooperates with the second screw rod 260 , and the contact 231 is connected to the electromagnetic scraper 210 .

[0074] By arranging a first motor 250 with a second screw rod 260 on the cleaning device 200, the electromagnetic scraper strip 210 is rotatably connected to the second bracket 240, the second bracket 240 is rotatably connected to the first bracket 230 with the contact 231, the first bracket 230 cooperates with the second screw rod 260, and the contact 231 cooperates with the guide rail 121 on the workbench 120. When cleaning, the first motor 250 is started, the first motor 250 drives the second screw rod 260 to rotate, and the second screw rod 260 drives the first bracket 230 to move on the guide rail 121. At the same time, the contact 231 on the first bracket 230 is connected to the guide rail 121. The electromagnetic scraper 210 is energized and has magnetism to facilitate the cleaning of metal debris. After the cleaning is completed, the first bracket 230 has been placed at the other end of the workbench 120. At this time, the contact 231 on the first bracket 230 is disconnected from the guide rail 121, and the electromagnetic scraper 210 is powered off and loses its magnetism, and shakes off the attached debris through the vibration component 220. Then the first motor 250 reverses to reset the cleaning device 200, so that the equipment has the function of automatic cleaning, and the cleaning device 200 can clean the debris in time to keep the workbench 120 flat. The pre-processed parts are processed on the flat workbench 120 to reduce the defective rate and improve the processing quality.

[0075] Furthermore, the vibration assembly 220 includes:

[0076] A second motor 221 mounted on the first bracket 230;

[0077] A rotating shaft 222 including an oblique shaft 223;

[0078] The oblique shaft 223 is rotationally connected to the electromagnetic scraper 210 , and the rotating shaft 222 is connected to the second motor 221 .

[0079] By arranging a second motor 221 with a rotating shaft 222 on the vibration component 220, and connecting the rotating shaft 222 to the inclined shaft 223, and rotatingly connecting the inclined shaft 223 to the electromagnetic scraper 210, when the vibration component 220 is working, the second motor 221 installed on the first bracket 230 is started, and the second motor 221 drives the rotating shaft 222 and the inclined shaft 223 to rotate. Since the electromagnetic scraper 210 is rotationally connected to the second bracket 240, and the second bracket 240 is rotationally connected to the first bracket 230, the rotating inclined shaft 223 drives the electromagnetic scraper 210 to reciprocate in the second bracket 240, and at the same time drives the second bracket 240 to reciprocate in the first bracket 230, so that the electromagnetic scraper 210 can fully shake off debris after reciprocating rotation in two directions, thereby extending the working life of the electromagnetic scraper 210.

When the hydraulic press body 100 is abnormal or the hydraulic block 130 suddenly drops due to misoperation by the staff, the first screw rod 310 rotates at a high speed. During the rotation, the claw 350 is subjected to a large inertial centrifugal force, and the claw 350 is opened by the spring 340 and cooperates with the limiting groove 360 ​​to fix the first protection block 320 and the second protection block 330, thereby stopping the first screw rod 310, that is, stopping the hydraulic block 130 from descending. A speed sensor 370 is also connected to the first screw rod 310, and the speed sensor 370 is connected to a buzzer 380. When the speed sensor 370 detects that the speed of the first screw rod 310 is too fast, a signal is sent to the buzzer 380, causing the buzzer 380 to alarm to remind the staff.

The protective plate 410 can block the flying chips generated when the hydraulic press is working to improve the safety protection effect, and the staff can observe the working condition of the hydraulic press through the observation window 411 on the protective plate 410. After the work is completed, the hydraulic block 130 rises and drives the first screw rod 310 to reverse, and the bevel gear 311 on the first screw rod 310 drives the transmission block 430 to reverse, and the chain 420 drives the protective plate 410 to descend through the transmission between it and the transmission block 430, and the counterweight block 440 rises accordingly, so that the staff can perform manual auxiliary operations on the workbench 120.

[0098] By arranging bristles 211 on the electromagnetic scraper strip 210, the electromagnetic scraper strip 210 can clean non-metallic debris through the bristles 211, thereby expanding the application range of the present device. The hydraulic press body 100 is also provided with a chip collection box 140. When the vibration component 220 is working, the debris shaken off the electromagnetic scraper strip 210 can be placed in the chip collection box 140 to avoid affecting the working environment around the hydraulic press body 100.
