Description

Technical Field

[0001] This utility model belongs to the technical field of six-sided top press equipment, and in particular relates to a standard block for calibrating hammers in a six-sided top press. Background Technology

[0002] In the application of six-sided top press technology, the equipment needs to be standardized and calibrated after installation to meet the requirements of high-temperature and high-pressure operation. This is a crucial preliminary step to ensure its stable operation. This calibration revolves around two core dimensions: the synchronization adjustment of the six working hydraulic cylinders and the alignment adjustment of the six carbide top hammers. These two aspects together form the foundation for the precise operation of the equipment. The synchronization adjustment balances the filling rate of each hydraulic cylinder by adjusting the opening and closing amplitude of the six corresponding throttle valves on the hydraulic station, ensuring consistent filling and forward speeds and avoiding top hammer deviation. The alignment adjustment of the top hammers directly affects the core performance of the equipment, ensuring precise alignment. This ensures good sealing of the high-pressure chamber and uniform force on the top hammers, fundamentally avoiding "explosion" accidents. The top hammers need to be guided to a mutually centered state and a suitable working position. In traditional calibration, the centering adjustment of the top hammers requires first placing the test block, driving the six top hammers to squeeze the test block tightly, pausing the oil pump, tightening the steel ring screws, and then retracting the top hammers. Next, the standard block is placed on the left, rear, and lower fixed top hammers, and the right, front, and upper moving top hammers are driven forward. The hammer surface of the top hammer is aligned with the edge of the standard block by fine-tuning screws or tapping to achieve centering. Finally, the stroke of the moving top hammers is adjusted with the stroke block. The equipment can only be operated normally after all calibrations are completed.

[0003] Chinese patent application CN206325528U discloses a standard block for calibrating the top hammer of a six-sided top press. The standard block includes a main body and an auxiliary body. The main body is a cube-shaped iron block with a grooved guide rail at its lower part. The auxiliary body is a cuboid with a square bottom surface that coincides with the bottom surface of the main body. A slider that precisely engages with the grooved guide rail is located on the opposite side of the bottom surface of the auxiliary body. The auxiliary body is made of wood or plastic. This invention divides the standard block into a main body and an auxiliary body. The auxiliary body uses a material with low hardness, effectively reducing the cumbersome procedure of calibrating the top hammer and the probability of a "hammer collision" accident.

[0004] Although this patent employs a split design, with the main body being a cube-shaped iron block to ensure calibration accuracy and the auxiliary parts made of low-hardness materials such as wood or plastic, and the two can be detachably assembled via trapezoidal or T-shaped grooved guide rails and sliders, it satisfies the conventional calibration requirements of the five top hammers (lower, left, right, front, and rear) and solves the pain point of the top hammer calibration. However, there is a deficiency in the calibration process of the top hammer. In existing technologies, in order for the standard block to contact the top hammer to complete the centering adjustment, the top hammer must first be lowered to a suitable position, while an additional support object is placed on the lower hammer, and then the standard block is placed on top of the support object, depending on the height of the support object. The compensation method for achieving contact between the standard block and the top hammer requires additional support objects and repeated adjustments to their position and height, significantly increasing the workload of the hammer calibration process and extending the calibration cycle. Furthermore, the pressure generated when the top hammer contacts the standard block directly acts on the traditional integral rigid standard block. Long-term exposure to such pressure can easily cause slight deformation of the standard block, resulting in dimensional deviations. With increased usage, the calibration accuracy of the standard block will be greatly reduced, failing to provide accurate guidance for the top hammer alignment and thus affecting the operational stability of the six-sided top press.

[0005] To address these issues, we provide a standard block for calibrating the hammer of a six-sided top press. Utility Model Content

[0006] The purpose of this utility model is to provide a standard block for calibrating the hammer of a six-sided top press. Through the cooperation of magnetic components and countersunk bolts, it solves the problems of large workload and inconvenient disassembly of magnetic plates in the existing technology of calibrating the hammer of a six-sided top press.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0008] This utility model relates to a standard block for calibrating a six-sided top press hammer. It includes a standard block body, which is a hollow iron block in the shape of a cube. A magnetic attraction assembly is provided on the surface of the standard block body. The magnetic attraction assembly includes three square slots, evenly distributed on the top, left, and rear sides of the standard block body. A magnetic shielding plate is slidably connected to the inner cavity of each square slot, and a magnetic attraction plate is slidably connected to the inner cavity of each magnetic shielding plate. The inner side of the magnetic attraction plate is detachably connected to the standard block body. Both the magnetic attraction plate and the magnetic shielding plate are square. The shape allows for precise fitting with the square slot, ensuring no offset or wobbling within the slot. Through holes are provided in the middle of both the magnetic plate and the magnetic shielding plate, allowing countersunk bolts to pass through and connect the magnetic plate and magnetic shielding plate to the standard block body. The sum of the attractive forces of the three magnetic plates must not be less than the weight of the standard block body. Because the top hammer is made of hard alloy containing ferromagnetic cobalt, the standard block body with magnetic attraction can be adsorbed onto the top hammer. When selecting magnetic plates, their magnetic force should not be too strong to ensure easy handling when moving them.

[0009] The present invention is further configured such that the inner cavity of the magnetic shielding plate is provided with a groove, and the inner cavity of the groove is slidably connected to the magnetic suction plate. The groove can prevent the magnetic suction plate from shifting laterally during assembly or use, and ensure that the magnetic suction plate always maintains a preset positional relationship with the magnetic shielding plate.

[0010] The present invention is further configured such that a countersunk bolt is slidably connected to the inner side of the magnetic suction plate, the bottom of the countersunk bolt passes through the top of the magnetic suction plate and is threadedly connected to a nut, the nut is located in the inner cavity of the standard block body, the nut is built into the inner cavity of the standard block body and is not exposed to the external environment, which can prevent external dust and oil stains from affecting the stability of the threaded connection during the calibration hammer, and can also avoid accidental bumps and damage to the nut leading to connection failure.

[0011] The present invention is further configured such that the standard block body has slots on its upper, left and rear sides, and the countersunk bolt is slidably connected to the slots. The slots allow the countersunk bolt to penetrate the surface of the standard block body and enter the inner cavity of the standard block body to connect with the nut.

[0012] The present invention is further configured such that the surface of the standard block body is provided with an inner recessed groove, the number of the inner recessed grooves is three, and they are respectively located on the right, front and bottom sides of the standard block body. The inner recessed grooves penetrate into the inner cavity of the standard block body. When installing magnetic plates on different sides, the nuts and countersunk bolts can be connected through the corresponding inner recessed grooves. The depth of the inner recessed groove is five-sixths of the side length of the standard block body.

[0013] The present invention is further configured such that, after the magnetic suction plate and the magnetic isolation plate are stacked together, their thickness is one millimeter less than the depth of the square groove. The thickness of the stacked magnetic suction plate and the magnetic isolation plate being less than that of the square groove can reserve a reasonable gap for their assembly, and avoid the thickness exceeding the groove depth due to minor dimensional errors in the component processing.

[0014] The present invention is further configured such that the thickness of the magnetic shielding plate is three millimeters, and the maximum size of the magnetic shielding plate is one millimeter smaller than the square groove. The thickness of the magnetic shielding plate can ensure the magnetic shielding effect, effectively block the magnetic field interference between the magnetic plates, avoid the mutual influence of multiple magnetic attraction leading to disorder of the adsorption force, and control the weight and volume of the magnetic shielding plate itself, without adding extra burden to the overall body of the standard block.

[0015] The present invention has the following beneficial effects.

[0016] 1. The standard block body of this utility model adopts a three-sided magnetic attraction design, with magnetic plates embedded in three sides. When calibrating the hammer, there is no need to place a support under the standard block. The standard block can be attracted to the surface of the hammer simply by bringing the hammer close. This avoids the standard block's dimensional accuracy deviation and pressure-induced dimensional changes caused by traditional auxiliary supports, ensuring the stability of the hammer calibration accuracy. It also prevents the standard block from accidentally falling off and causing safety accidents. At the same time, the hollow design inside the standard block reduces weight, improves the stability of magnetic adhesion, and facilitates the operator's handling. The overall design is simple, efficient, and easy to implement, taking into account accuracy, safety, and convenience, and comprehensively improving the efficiency and reliability of hammer calibration.

[0017] 2. In this utility model, the countersunk bolt that slides on the inner side of the magnetic plate, together with the threaded connection of the bottom through the magnetic plate and the magnetic shielding plate and the nut, forms a stable and detachable fixing structure. This connection method can accurately position the relative positions of the magnetic plate, the magnetic shielding plate and the standard block, avoid the offset during the assembly process, ensure that the magnetic plate is always in the preset working position, provide a structural foundation for the stable performance of the three-sided magnetic attraction function, and thus ensure the accuracy and consistency of the top hammer calibration.

[0024] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Example 1

[0026] Please see Figure 1-4This utility model is a standard block for calibrating a six-sided top press, including a standard block body 1, which is a hollow iron block in the shape of a cube. A magnetic attraction component 2 is provided on the surface of the standard block body 1. The magnetic attraction component 2 includes three square grooves 201, which are evenly distributed on the top, left and rear sides of the standard block body 1. A magnetic shielding plate 202 is slidably connected to the inner cavity of the square groove 201. A magnetic attraction plate 203 is slidably connected to the inner cavity of the magnetic shielding plate 202. The inner side of the magnetic attraction plate 203 is detachably connected to the standard block body 1.

[0027] Specifically: Both the magnetic suction plate 203 and the magnetic shielding plate 202 are square, which can be precisely matched with the square groove 201 to ensure that the two are not offset or shaken in the groove. Both the magnetic suction plate 203 and the magnetic shielding plate 202 have through holes in the middle so that the countersunk bolts 4 can pass through the through holes to connect the magnetic suction plate 203 and the magnetic shielding plate 202 to the standard block body 1. The sum of the attraction forces of the three magnetic suction plates 203 shall not be less than the weight of the standard block body 1. Since the top hammer is made of hard alloy and contains ferromagnetic cobalt, the standard block body 1 with magnetic attraction function can be attracted to the top hammer. When selecting the magnetic suction plate 203, its magnetic force should not be too large to ensure that it is easy to pick up when moving it.

[0028] Example 2

[0029] Please see Figure 1-4 Based on Embodiment 1, the inner cavity of the magnetic shielding plate 202 is provided with a groove 3, and the inner cavity of the groove 3 is slidably connected to the magnetic suction plate 203. A countersunk bolt 4 is slidably connected to the inner side of the magnetic suction plate 203. The bottom of the countersunk bolt 4 passes through the top of the magnetic suction plate 203 and the magnetic shielding plate 202 and is threadedly connected to a nut 5. The nut 5 is located in the inner cavity of the standard block body 1. The upper, left and rear sides of the standard block body 1 are provided with slots 6, and the countersunk bolt 4 is slidably connected to the slots 6. The surface of the standard block body 1 is provided with inner recessed grooves 7. There are three inner recessed grooves 7, which are located on the right, front and lower sides of the standard block body 1, respectively. After the magnetic suction plate 203 and the magnetic shielding plate 202 are stacked together, their size and thickness are one millimeter smaller than the depth of the square groove 201. The thickness of the magnetic shielding plate 202 is three millimeters, and the maximum size of the magnetic shielding plate 202 is one millimeter smaller than the square groove 201.

[0030] Specifically: the groove 3 prevents the magnetic plate 203 from shifting laterally during assembly or use, ensuring that the magnetic plate 203 always maintains a preset positional relationship with the magnetic shielding plate 202. The nut 5 is built into the inner cavity of the standard block body 1 and is not exposed to the external environment, which can prevent external dust and oil from affecting the stability of the threaded connection during hammer calibration and also prevent the nut 5 from being accidentally damaged, leading to connection failure. The slot 6 allows the countersunk bolt 4 to penetrate the surface of the standard block body 1 and enter the inner cavity of the standard block body 1 to connect with the nut 5. The inner countersunk groove 7 penetrates into the inner cavity of the standard block body 1. When installing magnetic plates 203 on different sides, they can be connected through the corresponding inner countersunk groove. 7. Connect the nut 5 to the countersunk bolt 4. The depth of the inner groove 7 is five-sixths of the side length of the standard block body 1. This avoids the component protruding and affecting the fitting accuracy between the standard block body 1 and the top hammer. The superimposed thickness of the magnetic suction plate 203 and the magnetic shielding plate 202 is less than that of the square groove 201, which can reserve a reasonable gap for their assembly. This avoids the superimposed thickness exceeding the groove depth due to minor dimensional errors in component processing. The thickness of the magnetic shielding plate 202 can ensure the magnetic shielding effect, effectively block the magnetic field interference between the magnetic suction plates 203, and avoid the mutual influence of multi-faceted magnetic attraction, which can lead to disordered adsorption force. It can also control the weight and volume of the magnetic shielding plate 202 itself, without adding extra burden to the overall standard block body 1.

[0031] The working principle of this utility model is as follows: When in use, the six hammers are distributed inwards, with the top, bottom, left, right, and front / back hammers corresponding to three axes, and the centers of the three axes intersecting at one point. The positions of the left, back, and bottom hammers are fixed, while the right, front, and top hammers can move linearly along their respective axes. When calibrating the top hammer, it is moved downwards to a distance of 10 to 15 millimeters from the edge of the left and back hammer surfaces and then attached to the hammer surfaces of the left, back, and top hammers using the three magnetically attached surfaces of the standard block body 1. If the top hammer is tilted, its hammer surface will not coincide with the corresponding attachment surface of the standard block body 1. By observing this positional deviation, the top hammer can be accurately calibrated to ensure that it is aligned with the other hammers.

[0032] The preferred embodiments of the present utility model disclosed above are only used to help illustrate the present utility model. The preferred embodiments do not describe all the details in detail, nor do they limit the present utility model to the specific implementation methods described. The present specification selects and specifically describes these embodiments in order to better explain the principle and practical application of the present utility model, so that those skilled in the art can better understand and utilize the present utility model.
