Description

Technical Field

[0001] This invention relates to the field of hydraulic press technology, and in particular to a modular prestressed steel wire winding ultra-high pressure hydraulic press host. Background Technology

[0002] The modular prestressed steel wire winding ultra-high pressure hydraulic press is a core piece of equipment in the fields of large-tonnage precision forging and special material forming. Its core features are: the upper beam, lower beam, and left and right columns adopt a modular split and splicing structure to form a closed frame. The outer wall of the frame is wound with high-strength prestressed steel wire, and the working tensile stress is offset by pre-compression stress to achieve ultra-high pressure load, high rigidity and long service life; at the same time, the modular design can solve the industry pain points of processing and transporting ultra-large tonnage equipment.

[0003] However, during long-term use, the prestressed steel wires wrapped around the outer walls of the upper and lower beams are affected by the relaxation of steel wire stress, compaction of module joint surfaces, equipment vibration, and temperature changes, which can lead to a gradual reduction in prestress and stress attenuation. Existing technologies lack quantifiable stress adjustment methods and rely solely on experience to judge whether the prestress is insufficient. This can easily result in over-adjustment leading to steel wire breakage or under-adjustment leading to a decrease in frame stiffness, making it impossible to accurately restore the prestress to the design prestress, thus affecting the pressing accuracy and operational safety of the equipment.

[0004] Therefore, a modular prestressed wire winding ultra-high pressure hydraulic press host is provided to solve the problems mentioned above. Summary of the Invention

[0005] The purpose of this invention is to solve the problems mentioned in the background art and to propose a modular prestressed steel wire winding ultra-high pressure hydraulic press host.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A modular prestressed wire-wound ultra-high pressure hydraulic press main unit includes a main unit base, on which a lower beam wound with wire rope is mounted, and further includes: The detection chamber is located inside the main unit base; A pressure bar, slidably connected within the lower beam, is used to compress the wire rope, thereby adjusting the stress of the wire rope; An adjustment assembly is installed inside the detection chamber; the adjustment assembly is used to adjust the position of the pressure rod. A pressure sensor is installed inside the pressure rod, and the pressure sensor is used to detect the stress in the wire rope.

[0008] Preferably, the adjustment assembly includes a worm, a turbine, and a cam. The cam is fixedly connected to a cam, and the worm and turbine are rotatably connected inside the detection chamber. The worm and turbine are meshed together. The rotation of the worm causes the turbine to drive the cam to rotate, which in turn causes the pressure rod to be pressed against the surface of the cam, thereby causing the pressure rod to press the wire rope outward, thus increasing the stress on the wire rope.

[0009] Preferably, the pressure rod has a mounting cavity, the pressure sensor is installed in the mounting cavity, the pressure sensor has multiple sets of detection heads, and the pressure detection ends of the detection heads all face the wire rope. The pressure sensor is connected to a display screen, which is located in the detection cavity and is used to display the real-time pressure of the pressure sensor.

[0010] Preferably, the pressure rod is detachably fitted with a mounting cover plate at the mounting cavity.

[0011] Preferably, a limiting bushing is installed inside the detection cavity, and the worm gear is rotatably connected inside the limiting bushing.

[0012] Preferably, a rotating handle is fixedly connected to the worm gear.

[0013] Preferably, the pressure sensor is equipped with an algorithm module, which has a built-in prestress attenuation prediction model that can collect real-time stress data and identify abnormal states such as local loosening and overall relaxation of the prestressed steel wire.

[0014] Preferably, the algorithm module has an automatic stress steady-state determination function, which can monitor the stress fluctuation amplitude in real time. When the fluctuation value is lower than the set threshold and remains stable, it is determined that the stress in each part of the prestressed steel wire is uniform and interconnected.

[0015] Preferably, the algorithm module has built-in overtravel protection logic, which issues a warning through the display screen when the pre-compensation force approaches the allowable upper limit.

[0016] Preferably, the algorithm module has the function of storing historical adjustment data, including adjustment time, stress value before adjustment, pre-compensation force, and steady-state target stress value, forming a stress attenuation trend ledger.

[0017] Compared with the prior art, the present invention provides a modular prestressed wire winding ultra-high pressure hydraulic press host, which has the following beneficial effects: This invention features slidingly connected pressure rods on both the upper and lower beams. The pressure rods are driven by an adjustment component to push the prestressed steel wires. Combined with a built-in pressure sensor and display screen, it enables real-time stress monitoring, visual feedback, and precise adjustment. Operators can accurately restore the prestress of the steel wires to the design range based on the data displayed on the screen, solving the problem of prestress attenuation and ensuring the rigidity of the frame.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] Example: Refer to Figure 1-5A modular prestressed steel wire winding ultra-high pressure hydraulic press main unit includes a main unit base 1, which is integrally cast from high-strength cast steel and has anti-slip and shock-absorbing pads at its bottom. A lower beam 2, on which steel wire rope 3 is wound, is fixedly installed on the main unit base 1 by high-strength bolts. The lower beam 2 is an alloy steel forging, and its outer wall is machined with spiral winding grooves adapted to the steel wire rope 3. The steel wire rope 3 is a high-strength prestressed galvanized steel wire rope, which is wound circumferentially in a multi-layered, closely arranged manner in the winding grooves. The steel wire ropes of each layer are tightly bonded to form an integral prestressed bearing layer. The hydraulic press main unit also includes a detection chamber 101, which is set inside the main unit base 1. The detection chamber 101 is a closed cavity structure, and its opening is equipped with a removable maintenance cover. The inner wall of the cavity is coated with an anti-rust and wear-resistant coating, providing a dustproof and rust-proof installation environment for the internal components. The pressure rod 4 is slidably connected in the lower beam 2, and the pressure rod 4 and the lower beam 2 are fitted with a clearance fit with a fit accuracy of H8 / h7. The lower beam 2 has a guide hole that matches the pressure rod 4, and the inner wall of the guide hole is inlaid with a wear-resistant copper sleeve to reduce the wear of the pressure rod 4 during reciprocating sliding. The pressure rod 4 is used to compress the wire rope 3, thereby adjusting the stress of the wire rope 3. The adjustment component is installed in the detection cavity 101 and is used to adjust the position of the pressure rod 4. The pressure sensor 601 is installed in the pressure rod 4 and is a high-precision piezoelectric pressure sensor. The pressure sensor 601 is used to detect the stress of the wire rope 3.

[0022] The adjustment assembly includes a worm gear 501, a turbine 502, and a cam 503. The cam 503 is coaxially and fixedly connected to the turbine 502 via a flat key. A locking screw is provided at the flat key connection to prevent relative rotation between the cam 503 and the turbine 502. Both the worm gear 501 and the turbine 502 are rotatably connected within the detection chamber 101. The turbine 502 is rotatably connected within the detection chamber 101 via a limiting sleeve. The limiting sleeve is a needle roller bearing type limiting structure, which allows for flexible rotation of the turbine 502 while strictly limiting its axial displacement. The worm gear 501 is meshed with the turbine 502. A single-headed worm gear is used to form a 1:20 transmission ratio with the turbine 502. By utilizing the speed reduction and torque increase characteristics of the worm gear, the operation is labor-saving while achieving a slight adjustment of the prestress. The rotation of the worm gear 501 causes the turbine 502 to drive the cam 503 to rotate. The surface of the cam 503 then presses against the pressure rod 4. The cam 503 adopts an involute profile design, and the slope of its convex section changes linearly, so that the pushing action of the pressure rod 4 is smooth and impact-free, avoiding damage to the wire rope 3 due to excessive instantaneous force. This causes the pressure rod 4 to press the wire rope 3 outward, thereby increasing the stress on the wire rope 3.

[0023] The pressure rod 4 has a mounting cavity 401, the size of which is adapted to the shape of the pressure sensor 601. The inner wall of the cavity has a wire hole for cable routing, and the inner wall of the wire hole is equipped with a rubber protective sleeve to prevent the cable from being worn by sharp edges. The pressure sensor 601 is installed in the mounting cavity 401 by fixing bolts. The pressure detection end of the pressure sensor 601 faces the wire rope 3, and the pressure sensor 601 is connected to the display screen 602 through a shielded cable. The shielded cable can effectively resist electromagnetic interference during the operation of the hydraulic press and ensure the stability of stress data transmission. The display screen 602 is located in the detection cavity 101. The display screen 602 adopts an industrial-grade LCD screen, which has the characteristics of being waterproof, dustproof, and vibration resistant. Its display interface is divided into two main areas: a data display area and a status prompt area, which are used to display the real-time pressure of the pressure sensor 601.

[0024] The pressure rod 4 is detachably mounted with a mounting cover 402 at the mounting cavity 401. The mounting cover 402 and the pressure rod 4 are detachably connected by hexagon socket bolts. A rubber sealing gasket is provided at the contact surface between the cover and the pressure rod 4 to prevent external dust and oil from entering the mounting cavity 401 and to protect the detection accuracy of the pressure sensor 601.

[0025] A limiting sleeve 504 is fixedly installed in the detection cavity 101 by welding. The limiting sleeve 504 is made of alloy steel and has a lubricating oil groove machined on its inner wall. It forms an oil film lubrication with the worm 501 to reduce rotational friction resistance. The worm 501 is rotatably connected in the limiting sleeve 504. The worm 501 and the limiting sleeve 504 adopt a clearance fit to ensure the flexible rotation of the worm 501 and avoid radial movement during rotation.

[0026] The end of the worm gear 501 away from the turbine 502 extends to the outside of the detection chamber 101 and is fixedly connected to a rotating handle 505 via a spline. The gripping part of the rotating handle 505 is covered with an anti-slip rubber sleeve, and the surface of the rubber sleeve is machined with anti-slip textures to facilitate stable gripping by the operator when their hands are oily. An elastic retaining ring is provided at the spline connection between the handle and the worm gear 501 to achieve axial positioning.

[0027] The working principle of this device is as follows: During operation, rotating the handle 505 drives the worm gear 501 to rotate. The worm gear 501 rotates smoothly within the limiting sleeve 504, and its tooth profile precisely meshes with the tooth profile of the turbine 502. Through meshing transmission, the turbine 502 and the cam 503 rotate synchronously. The outer edge of the cam 503 contacts the bottom end of the pressure rod 4. The bottom end of the pressure rod 4 is machined with an arc-shaped groove that matches the profile of the cam 503, increasing the contact area between the two and avoiding local stress concentration that could lead to component wear. As the cam 503 rotates, its protruding section gradually squeezes the pressure rod 4, causing the pressure rod 4 to slide upward along the guide structure of the lower beam 2, thereby pushing the wire rope 3. The top end of the pressure rod 4 is an arc-shaped contact surface that matches the outer diameter of the wire rope 3, so that the pushing force can be evenly transmitted to the surface of the wire rope 3, thereby compensating for and increasing the pre-tension stress of the wire rope 3.

[0028] In practical use, the steel wire rope 3 is wound around the outer wall of the lower beam 2 with a designed pre-tension force. The designed pre-tension force is set according to the rated working pressure of the hydraulic press, which is usually 1.2-1.5 times the tensile stress generated by the rated working pressure. The pressure sensor 601 detects the initial stress value and transmits it to the display screen 602 in real time through a shielded cable. The data display area of ​​the display screen 602 will simultaneously display the real-time detection values ​​and average values ​​of multiple detection heads. The operator can read the reference stress data and use this data as a reference for subsequent stress adjustment.

[0029] After the equipment has been running for a long time, it will be affected by factors such as stress relaxation of the wire rope 3, compaction of the splicing surface between the lower beam 2 and the column, and vibration of the equipment. If the stress value displayed on the display screen 602 is lower than the design threshold, the design threshold is 90% of the design pretension force. This threshold is preset in the algorithm module according to the allowable stress of the wire rope 3 and the stiffness requirements of the hydraulic press, and it is determined that the wire rope 3 has insufficient pretension force and stress attenuation.

[0030] The operator rotates the handle 505, which drives the cam 503 to rotate via the worm gear 501 and worm wheel 502. Due to the self-locking characteristic of the worm gear transmission pair, the position of the pressure rod 4 can be stably maintained with each rotation of the handle, and there will be no rebound. The cam 503 squeezes the pressure rod 4 and pushes the wire rope 3 upward, gradually increasing the pre-tension stress of the wire rope 3. During this process, the pressure sensor 601 continuously collects stress data and displays it synchronously on the display screen 602. The status prompt area of ​​the display screen 602 will display the "Adjusting" status indicator in real time.

[0031] When the stress value displayed on the screen 602 returns to the design preset range, stop rotating the rotating handle 505 to complete the pre-tightening compensation. The self-locking characteristic of the worm gear will fix the position of the adjusting component, and the pressure rod 4 will maintain the pushing state on the wire rope 3 to ensure that the prestress of the wire rope 3 is maintained at a suitable level, ensuring the structural rigidity and operational stability of the hydraulic press host, and avoiding micro-deformation of the frame during operation of the hydraulic press due to insufficient prestress, which would affect the pressing accuracy of the workpiece.

[0032] Specifically, the upper beam of the hydraulic press host adopts a structural design that is completely identical to that of the lower beam 2. The upper beam and the lower beam 2 are symmetrical components, and their processing technology and dimensional accuracy are consistent. They also integrate the functions of prestressed steel wire rope 3 winding and stress adjustment. High-strength prestressed steel wire rope 3 is wrapped around the outer wall of the upper beam. The winding method, number of layers, and pre-tension setting of the steel wire rope of the upper beam are the same as those of the lower beam 2. Together with the steel wire rope 3 of the lower beam 2 and the left and right columns, they form a closed prestressed frame. The upper beam is internally connected to the pressure rod 4. The guide hole and wear-resistant copper sleeve of the upper beam are completely consistent with those of the lower beam 2. The top of the pressure rod 4 extends out of the outer wall of the upper beam and abuts against the wire rope 3, which is used to push and adjust the pre-tightening stress of the wire rope 3 of the upper beam. The upper beam is equipped with a cavity with the same function as the detection cavity 101 of the lower beam. The size and maintenance structure of the cavity are the same as those of the detection cavity 101. It is also coated with an anti-rust and wear-resistant coating. The internal adjustment components (worm gear 501, turbine 502, cam 503) are the same as those of the lower beam. The specifications and transmission ratio of the upper beam adjustment components are exactly the same as those of the lower beam adjustment components to ensure the consistency of the upper and lower beam adjustment operations. The adjustment components drive the pressure rod 4 to move along the upper beam guide structure to realize the compensation and adjustment of the stress of the upper beam wire rope 3. The pressure rod 4 has an internal mounting cavity 401, and the pressure sensor 601 is fixedly installed inside the mounting cavity 401. The pressure rod 4 has a detachable mounting cover 402 at the opening of the mounting cavity 401, which can not only seal the mounting cavity 401 and protect the internal sensor, but also facilitate the subsequent disassembly, maintenance and calibration of the sensor. The mounting cover 402 and sealing gasket on the upper beam side are of the same specifications as those on the lower beam side, so as to realize the commonality of spare parts.

[0033] The pressure sensor 601 is equipped with multiple sets of detection heads, with a total of 3 sets of detection heads evenly distributed around the top of the pressure rod 4. The included angle between adjacent detection heads is 120°. The pressure detection end of each set of detection heads is positioned facing the wire rope 3. Through multi-point synchronous detection, stress data at different points on the wire rope 3 are collected. The algorithm module calculates the average value of the detection data from the 3 sets of detection heads, eliminates abnormal data, further improves detection accuracy, avoids errors from single-point detection, and improves the precision of stress detection.

[0034] The pressure sensor 601 is electrically connected to the display screen 602. The display screen 602 is fixedly installed on the inner wall of the detection chamber 101 and is used to display the stress data collected by the pressure sensor 601 in real time, and at the same time display various parameters and prompt information analyzed by the algorithm module. The parameter display area of the display screen 602 will simultaneously present three core data: the current stress value, the standard stress value, and the pre-compensation target force, providing an intuitive adjustment basis for the operator.

[0035] With the above structure, the upper beam can achieve the same precise prestress compensation as the lower beam 2. The operator adjusts the upper beam adjustment component and combines the stress feedback of the display screen 602 to restore the pre-tightening force of the upper beam steel wire rope 3 to the design range. After the prestress compensation of the upper and lower beams is completed, the algorithm module will compare the steady-state stress values of the two. If the difference exceeds 5%, a prompt will be issued through the display screen 602 to facilitate the operator to further fine-tune and ensure the even stress on the whole machine.

[0036] Among them, the upper beam, the lower beam 2, and the left and right columns all adopt a split modular design. Each module is independently processed and formed. The processing of each module is completed on a special fixture. The splicing joints of the modules are positioned by biting with a precision mating surface. A micro-tooth-shaped positioning structure is processed at the precision mating surface to enhance the biting friction between the modules. After splicing, a complete frame is formed. After the module splicing is completed, an auxiliary positioning will be carried out through a positioning pin to further improve the overall connection stiffness of the frame. The connection stiffness between the modules is equivalent to that of an integral forging, which is convenient for processing, transportation and on-site assembly. The weight of a single module does not exceed 1 / 4 of the overall frame and can be adapted to conventional transport vehicles and lifting equipment.

[0037] Furthermore, regarding the algorithm module: The algorithm module supporting the pressure sensor 601 is the core intelligent analysis unit, which is integrated into the host control circuit. The algorithm module uses an embedded microprocessor and has the integrated functions of data acquisition, analysis, storage, and output. Its operation frequency can reach 100 MHz, which can quickly process stress detection data, cooperate with the pressure sensor 601 and the display screen 602 in a linkage manner, and has four core functions: (1) Prestress attenuation prediction and abnormal identification function: The algorithm module has a built-in prestress attenuation prediction model. This model is established based on historical data such as the material properties, service life, and working load of the steel wire rope 3. It can receive stress data transmitted by multiple detection heads of the pressure sensor 601 in real time, integrate and analyze the data, and compare with the preset standard stress threshold. When the deviation between the detection value of a single detection head and the average value exceeds 10%, it is determined as local loosening; when the average value is lower than the design threshold, it is determined as overall relaxation, accurately identifying the stress state of the steel wire rope 3, distinguishing two types of abnormal states: local loosening and overall relaxation, and determining whether stress compensation operations need to be carried out to avoid misjudgment and missed judgment.

[0038] (2) Automatic stress steady state determination function: The algorithm module can monitor the fluctuation range of stress data in real time and set the stress fluctuation stability threshold. The stress fluctuation stability threshold is set to ±1% of the standard stress value, and the continuous stability time is set to 30s. During the stress adjustment process, if the collected stress fluctuation value is lower than the set threshold and the continuous stability time reaches the preset standard, the algorithm module automatically determines that the internal stress of the wire rope 3 has been transmitted and diffused, and the stress in each part is uniformly connected, avoiding the false standard of local tightness and overall relaxation.

[0039] (3) Overtravel protection warning function: The algorithm module has built-in allowable stress upper limit parameter of wire rope 3. The allowable stress upper limit is 80% of the breaking stress of wire rope 3. This parameter is pre-entered according to the product specifications of wire rope 3 to form overtravel protection logic. During the stress adjustment process, the real-time stress value is compared with the allowable stress upper limit in real time. When the pre-compensation force is close to the allowable upper limit, when the real-time stress value reaches 90% of the allowable upper limit, an audible and visual warning prompt is immediately issued through the display screen 602. The display screen 602 will flash a red warning light and pop up the text prompt "Stress is about to exceed the limit, please stop adjusting" to remind the operator to stop adjusting and eliminate the risk of wire rope 3 breaking due to stress overload.

[0040] (4) Historical data storage ledger function: The algorithm module has a data storage function, with a built-in large-capacity storage chip that can store no less than 500 adjustment data. It can automatically record the core data of each stress adjustment, including adjustment time, initial stress value before adjustment, pre-compensation force, and steady-state target stress value. The data is organized and archived to form a stress attenuation trend ledger. The ledger will automatically generate a stress attenuation curve, which will intuitively show the stress change law of the wire rope 3. It can be retrieved and viewed through the display screen 602, which is convenient for tracing the stress change law of the wire rope 3 and providing data support for the maintenance and replacement of the wire rope 3.

[0041] The adjustment process for the preload stress of the wire rope is as follows: The first step is power-on initialization: After the host is powered on, the algorithm module starts automatically and completes self-tests of the pressure sensor 601 and the display screen 602. If there is a fault in the equipment, the display screen 602 will display a fault code. The pressure sensor 601 synchronously collects the initial stress data of the wire rope 3 through multiple sets of detection heads and transmits it to the algorithm module. The algorithm module compares the initial stress with the preset standard stress value, analyzes the degree of stress attenuation, and displays the attenuation percentage on the display screen 602 to determine whether stress compensation is needed.

[0042] The second step is the pre-compensation force calculation and output: If compensation is determined to be required, the algorithm module uses the built-in pre-stress attenuation prediction model, combined with the loss law of uniform stress transmission. The loss law is derived from the stress drop value in historical adjustment data, which is usually 5%-8% of the standard stress value. The pre-compensation target force is calculated, which is greater than the standard design stress, to offset the drop difference after the subsequent uniform stress diffusion. The pre-compensation target force, standard stress and other parameters are simultaneously transmitted to the display screen 602. The display screen 602 will use different colors to mark the three data items, so that the operator can quickly distinguish them and intuitively display them to the operator.

[0043] The third step is manual adjustment in stages: The operator holds the rotating handle 505, which drives the worm gear 501 to rotate. Through the transmission of the turbine 502 and cam 503, the pressure rod 4 pushes the wire rope 3 in a small step-by-step manner. The range of the small adjustment is 1 / 6 turn of the rotating handle 505, which corresponds to a pushing displacement of 0.05mm for the pressure rod 4. After each adjustment, the operation is paused and the pressure holding state is entered. The pressure holding time is set according to the number of winding layers of the wire rope 3. The pressure holding time is 10 seconds for single-layer winding and 20 seconds for multi-layer winding. The internal stress of the wire rope 3 is allowed to slowly spread to various parts to avoid local stress accumulation caused by one-time pressure.

[0044] The fourth step is stress monitoring and compliance determination: the pressure sensor 601 continuously collects real-time stress data, the algorithm module analyzes it in real time, and updates the data every 1 second. The display screen 602 updates the stress data and change curves simultaneously. The operator makes continuous fine adjustments until the real-time stress reaches the pre-compensation target force output by the algorithm module. The status prompt area of ​​the display screen 602 will show "pre-compensation meets the standard", at which point the adjustment is paused.

[0045] Step 5, Steady-state confirmation and adjustment completion: The algorithm module continuously monitors stress fluctuations. Once the stress in each part of the wire rope 3 is naturally uniform, the stress value drops and stabilizes within the standard design stress range, and the fluctuation value meets the standard, the algorithm module will automatically record all the data of this adjustment and archive it. It will automatically determine that the adjustment is complete and issue a compliance prompt through the display screen 602. The display screen 602 will light up a green compliance indicator and pop up the text prompt "Adjustment completed, stress steady-state meets the standard", thus completing this prestress compensation operation.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
