Description

Technical Field

[0001] This utility model mainly relates to the field of shearing machine technology, specifically a positioning and shearing fixture for a shearing machine. Background Technology

[0002] In the manufacturing process of electrical equipment such as electrical cabinets and distribution boxes, high-precision shearing of cold-rolled steel plates and galvanized steel plates is required. The shearing quality of the plates directly affects the assembly accuracy and structural strength of the electrical cabinet.

[0003] When using existing shearing machine positioning fixtures to limit and fix sheet metal, the thickness of the sheet metal used in electrical cabinet processing varies greatly (typically 1.5-6mm). Traditional limiting components rely on preset pressure to clamp the sheet metal, and cannot sense the actual downward pressure in real time. When the sheet metal is thin, excessive downward pressure can easily cause local dents and deformation of the sheet metal, affecting the flatness of the electrical cabinet. When the sheet metal is thick, insufficient downward pressure cannot achieve reliable limiting, and the sheet metal is prone to displacement due to the impact force of the cutting tool during the shearing process, resulting in burrs, flash, or dimensional deviations (errors can reach ±1.5mm) at the sheared edges, requiring an additional grinding process and extending the production cycle.

[0004] In addition, electrical cabinet processing has high requirements for the surface quality of sheet metal. Traditional limit components may leave indentations or scratches on the sheet metal surface due to uncontrollable pressure. Especially for precision sheet metal such as galvanized steel sheet, surface damage will reduce its corrosion resistance and affect the service life of the electrical cabinet. At the same time, operators need to rely on experience to judge whether the limit pressure is appropriate. Without quantitative data support, it is difficult to ensure pressure consistency in multiple batches of production, resulting in poor product quality stability. Utility Model Content

[0005] This utility model provides a solution that is significantly different from existing technologies, addressing the problem that existing solutions are too simplistic. It mainly provides a positioning and shearing fixture for a shearing machine to solve the technical problems mentioned in the background.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0007] A positioning and shearing fixture for a shearing machine includes a fixed box. Inside the fixed box is a first hydraulic rod that drives a pressure plate to move. The bottom of the pressure plate is connected to a mounting plate via symmetrically arranged springs. The bottom of the pressure plate is equipped with a distance measuring component for detecting the distance between the pressure plate and the mounting plate. The bottom of the mounting plate is equipped with a stop post for pressing and limiting the material. The material is placed above an extension platform, which is installed inside a base. A movable cutting mechanism for cutting the material is installed inside the fixed box.

[0008] Preferably, the fixing box is fixedly installed on the inner side of the base, and the base is provided with a slanted groove for receiving the cutting strips on the side near the movable cutting mechanism.

[0009] Preferably, the extension platform includes extension rods, and the platform body is disposed between the extension rods.

[0010] Preferably, the movable cutting mechanism includes a cutting blade, and a second hydraulic rod for driving the cutting blade to move is provided inside the fixed box.

[0011] Preferably, the fixed box is provided with a movable through groove for the cutting blade and the abutment to move.

[0012] Preferably, a control panel is provided on one side of the base, and the control panel is electrically connected to the ranging component, the first hydraulic rod, and the second hydraulic rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] (1) By connecting the springs symmetrically arranged at the bottom of the pressure plate to the mounting plate, and combining the distance measuring component to detect the distance between the pressure plate and the mounting plate, the actual pressure of the abutment on the plate is inferred according to Hooke's Law, so as to realize the control of the pressure on plates of different thicknesses, avoid the shearing deviation caused by the denting and deformation of thin plates or the insufficient limit of thick plates, reduce the grinding process, and shorten the production cycle.

[0015] (2) By installing a sloping groove on one side of the base to receive the cutting strip, the accumulation of cutting waste is avoided from affecting the operation of the equipment. At the same time, the movable cutting mechanism drives the cutting blade to move through the second hydraulic rod. Combined with the control panel, automated shearing is achieved, which improves the processing efficiency.

The terminology used herein is for the purpose of describing particular embodiments and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0026] Please refer to the appendix carefully. Figure 1-4A positioning shearing fixture for a shearing machine includes a fixed box 1 with a first hydraulic rod 3 inside to drive a pressure plate 2 to move. The pressure plate 2 is slidably connected to the inside of the fixed box 1, thereby improving the stability of the pressure plate 2 during movement. The bottom of the pressure plate 2 is connected to a mounting plate 41 via symmetrically arranged springs 4. The springs 4 can be cylindrical helical compression springs. A limiting telescopic rod can be provided inside the springs 4 to prevent the springs 4 from bending and enhance structural stability. The limiting telescopic rod is existing technology and will not be described in detail. A ranging component 5 is provided at the bottom of the pressure plate 2 to detect the distance between the pressure plate 2 and the mounting plate 41. A stop post 7 is provided at the bottom of the mounting plate 41 to limit the downward pressure of the plate 6. A rubber sleeve can be provided at the bottom of the stop post 7. A moving slot is provided on the fixed box 1 for the movement of the stop post 7. The ranging component 5 can be a laser displacement sensor, model: KEYENCE. The IL-1000 control panel 10 can receive the detection data of the ranging component 5. The control panel 10 is existing technology. According to Hooke's Law, within the elastic limit, the elastic force F on the spring 4 is proportional to the deformation x of the spring 4, that is: F=k*x, where k is the spring constant of the spring 4 in N / m, which is determined by parameters such as the material, diameter, and number of coils of the spring 4; x is the deformation of the spring 4, that is, the difference between the initial distance and the distance after compression between the two plates. Therefore, by detecting the distance between the pressure plate 2 and the mounting plate 41, it can be inferred that the abutment 7 applies pressure to the plate 6 below it. At the same time, the setting of the spring 4 gives the limiting device a certain buffering performance.

[0027] The plate 6 is placed on the extension platform 8, and the extension platform 8 is installed inside the base 81. The extension platform 8 includes extension rods 83, and the platform body 82 is provided between the extension rods 83. The extension rods 83 can support the large-volume plate 6. The extension rods 83 are usually made of high-strength metal materials such as carbon steel or alloy steel, and have good load-bearing capacity and anti-deformation performance.

[0028] The fixed box 1 is equipped with a movable cutting mechanism 9 for cutting the plate 6. The movable cutting mechanism 9 includes a cutting blade 91. The fixed box 1 is provided with a moving through groove for the cutting blade 91 to move. The cutting blade 91 is fixedly installed below the blade mounting plate. The fixed box 1 can be provided with a vertical slide rod that is slidably connected to the blade mounting plate. The fixed box 1 is also provided with a second hydraulic rod 92 that drives the cutting blade 91 to move. The control panel 10 can control the second hydraulic rod 92.

[0029] The fixed box 1 is fixedly installed inside the base 81, and the base 81 is provided with a slanted groove for receiving the cutting strip on the side near the movable cutting mechanism 9.

[0030] The specific operating procedure of this utility is as follows: Place the plate 6 to be cut on the platform body 82 of the extension platform 8, adjust the position of the plate 6 so that the plate 6 is centered on the extension platform 8, and avoid shaking during the cutting process due to the shift of the center of gravity.

[0031] After placement, input the preset pressure value into the control panel 10 and simultaneously activate the first hydraulic rod 3. The first hydraulic rod 3 drives the pressure plate 2 to move downward. The pressure plate 2, through the spring 4, drives the mounting plate 41 and the abutment 7 to move downward. The abutment 7 gradually contacts the plate 6 and applies pressure to it. During the process, the ranging component 5 detects the distance between the pressure plate 2 and the mounting plate 41 in real time and transmits the data to the control panel 10. When the actual pressure displayed on the control panel 10 reaches the preset value, the first hydraulic rod 3 automatically stops running, completing the limiting and fixing of the plate 6. At this time, the spring 4 is in a compressed state, which has a certain buffering performance and can prevent excessive pressure from damaging the plate 6.

[0032] After the plate 6 is limited, the control panel 10 starts the movable cutting mechanism 9. The second hydraulic rod 92 drives the cutting blade 91 to move downward along the movable through groove on the fixed box 1 to cut the plate 6. After the cutting is completed, the cutting blade 91 returns to the initial position under the drive of the second hydraulic rod 92. The control panel 10 controls the first hydraulic rod 3 to drive the pressure plate 2, spring 4, mounting plate 41 and abutment 7 to move upward, releasing the limitation on the plate 6.

[0033] The present invention has been described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
