Description

Technical Field

[0001] This utility model relates to the field of fuel tank end cap processing technology, specifically a fuel tank end cap correction and shearing device. Background Technology

[0002] With the development of the automotive industry, the manufacturing precision requirements for metal fuel tanks are increasing. Fuel tank end caps are usually formed from rectangular metal plates through processes such as shearing and stamping. The first step is to place the metal fuel tank plate on the placement seat of a hydraulic shearing machine and cut off the four corners by extrusion to make its edges and corners rounded, so as to facilitate subsequent bending, edge rolling and welding.

[0003] In existing technology, the upper surface dimensions of the placement seat are basically consistent with the planar dimensions of the fuel tank plate to be processed. To avoid deviations during manual placement, several limiting posts are usually fixed on one horizontal and one vertical side of the placement seat. During operation, the worker needs to place the fuel tank plate flat on the placement seat and make fine adjustments to the plate horizontally and vertically by sight and touch until its adjacent two sides are simultaneously in contact with the corresponding limiting posts before the shearing action can be started.

[0004] However, the above positioning method has the following shortcomings: 1. Manual fine-tuning is time-consuming, with each placement and adjustment taking up more than half of the entire shearing cycle, severely restricting production efficiency; 2. The fine-tuning process relies on the experience of the workers. There are large differences between different operators, which can easily lead to inconsistent positioning, causing the arc cut position to deviate and resulting in defective products. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a tank end cap correction and shearing device. The device uses a hydraulic push rod to drive the lifting plate to move towards the placement seat. The metal plate is placed on the boss at the top of the placement seat. After the extrusion frame at the bottom of the lifting plate contacts the metal plate placed on the boss, the lifting plate continues to move downward. Since the groove inside the extrusion frame is the same size as the boss, the extrusion and shearing of the metal plate can be achieved.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A fuel tank end cap straightening and shearing device includes a worktable, a guide column on the worktable, a hydraulic drive device on the top of the guide column, a lifting and pressing device at the power output end of the hydraulic drive device, a placement seat on the upper surface of the worktable, guide and limiting devices on two opposite sides of the placement seat, and multiple limiting columns at one end of the placement seat.

[0007] Preferably, multiple limiting posts are provided on one of the horizontal sides of the placement seat, and guide limiting plates are provided on the two opposite vertical sides of the placement seat, and the guide limiting plates are arranged in a trumpet shape.

[0008] Preferably, the guide limiting plate includes a straight plate parallel to the side of the placement seat, the straight plate is located close to the limiting post, the straight plate is half the size of the placement seat, and an inclined plate is provided at the end of the straight plate away from the limiting post, the size of the inclined plate is greater than half the size of the placement seat.

[0009] Preferably, the distance between the two straight plates is the same as the size of the fuel tank end cap plate to be processed, and the guide limiting plate and the limiting post are both made of metal.

[0010] Preferably, the lifting and pressing device includes a lifting plate, and the lifting plate has through holes at its four corners. The lifting plate is connected to the guide column through the through holes.

[0011] Preferably, the hydraulic drive device includes a hydraulic push rod, the power output end of which passes through the top plate and is connected to the top of the lifting plate.

[0012] Preferably, the bottom of the lifting plate is provided with a pressing frame, the middle of the pressing frame has a groove, and the upper surface of the placement platform is provided with a boss that matches the groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model has a simple structure. By placing one end of a metal plate at the end of the placement seat, and then pushing the metal plate to the other end of the placement seat, it can contact the guide limiting device during the pushing process. The guide limiting device can ensure that the two opposite sides of the metal plate are kept in the same position with the placement seat until the operator pushes the metal plate to the end of the placement seat and abuts against the limiting post. At this time, the position of the metal plate is directly below the lifting and pressing device, which can ensure the processing accuracy of the metal plate, avoid the operator from fine-tuning the metal plate, reduce the labor intensity of the operator, and ensure the processing accuracy of the metal plate.

[0014] 2. Because the device has guide and limiting plates on both sides of the placement base, and the guide and limiting plates are flared, it can ensure that the metal plate is adjusted in position by the flared guide and limiting plates as it moves toward the limiting post, until the end of the metal plate abuts against the limiting post, at which point the metal plate is in the optimal processing position. Through the flared structure, the position of the metal plate can be finely adjusted step by step to ensure the processing accuracy of the metal plate.

[0015] 3. During the movement of the metal plate towards the limiting post, the metal plate first contacts one of the inclined plates. Guided by the inclined plates, the metal plate can be gradually fine-tuned in position during the movement until it moves to half of the placement seat. At this point, both sides of the metal plate can simultaneously contact the straight plate, and the end of the metal plate abuts against the limiting post. At this point, the metal plate is at the optimal processing angle, ensuring the processing accuracy of the metal plate.

[0016] 4. This device uses a hydraulic push rod to move the lifting plate towards the placement seat. The metal plate is placed on the boss at the top of the placement seat. After the extrusion frame at the bottom of the lifting plate contacts the metal plate placed on the boss, the lifting plate continues to move downward. Since the groove inside the extrusion frame is the same size as the boss, it can perform the extrusion and shearing work on the metal plate, ensuring that the edges and corners of the metal plate are processed into the required shape later.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1 A fuel tank end cap straightening and shearing device, the structure of which is as follows: Figures 1-3 As shown, the device includes a workbench 1, a guide post 2 on the workbench 1, a hydraulic drive device on the top of the guide post 2, a lifting and pressing device at the power output end of the hydraulic drive device, a placement seat 7 on the upper surface of the workbench 1, guide and limiting devices on two opposite sides of the placement seat 7, and multiple limiting posts 11 at one end of the placement seat 7.

[0021] When processing metal sheets, the operator places one end of the metal sheet on the end of the placement seat 7 and then pushes the metal sheet towards the other end of the placement seat 7. During the pushing process, the metal sheet comes into contact with the guide limiting device. The guide limiting device ensures that the two opposite sides of the metal sheet remain in the same position with the placement seat 7 until the operator pushes the metal sheet to the end of the placement seat 7 and abuts against the limiting post 11. At this time, the position of the metal sheet is directly below the lifting and pressing device, which ensures the processing accuracy of the metal sheet, avoids the operator from making fine adjustments to the metal sheet, reduces the operator's labor intensity, and ensures the processing accuracy of the metal sheet.

[0022] Multiple limiting posts 11 are provided on one of the horizontal sides of the placement seat 7, and guide limiting plates 10 are respectively provided on the two opposite vertical sides of the placement seat 7. The guide limiting plates 10 are arranged in a trumpet shape.

[0023] The operator places the metal plate on the horizontal side of the placement seat 7 away from the limiting post 11 and pushes the metal plate towards the limiting post 11. Since the placement seat 7 is provided with guide limiting plates 10 on both sides, and the guide limiting plates 10 are flared, it can ensure that the position of the metal plate is adjusted by the flared guide limiting plates 10 during the movement towards the limiting post 11, until the end of the metal plate abuts against the limiting post 11, at which point the metal plate is in the optimal processing position. Through the flared structure, the position of the metal plate can be finely adjusted step by step to ensure the processing accuracy of the metal plate.

[0024] The guide limiting plate 10 includes a straight plate 12 parallel to the side of the placement seat 7. The straight plate 12 is located close to the limiting post 11. The straight plate 12 is half the size of the placement seat 7. An inclined plate 13 is provided at the end of the straight plate 12 away from the limiting post 11. The size of the inclined plate 13 is greater than half the size of the placement seat 7.

[0025] As the metal plate moves toward the limiting post 11, it first contacts one of the inclined plates 13. Guided by the inclined plate 13, the metal plate can be gradually fine-tuned in position during the movement until it moves to half of the placement seat 7. At this point, both sides of the metal plate can simultaneously contact the straight plate 12. When the end of the metal plate abuts against the limiting post 11, the metal plate is at the optimal processing angle, ensuring the processing accuracy of the metal plate.

[0026] The distance between the two straight plates 12 is the same as the size of the oil tank end cap plate to be processed, and the guide limiting plate 10 and the limiting post 11 are both made of metal.

[0027] To ensure optimal machining accuracy, the metal plate is moved to contact the straight plate 12 and the limiting post 11. In addition, the metal limiting post 11 and the guide limiting plate 10 can prevent long-term collisions with the metal plate. Damage to the limiting post 11 and the guide limiting plate 10 will cause errors in the machining accuracy of the metal plate, resulting in an increase in scrap rate.

[0028] The lifting and pressing device includes a lifting plate 5, which has through holes at its four corners. The lifting plate 5 is connected to the guide column 2 through the through holes.

[0029] By connecting the lifting plate 5 to the four guide columns 2, it is ensured that the lifting plate 5 moves vertically along the guide columns 2 during lifting, ensuring stability when extruding and shearing the metal plate, and ensuring that the metal plate is extruded and sheared into shape in one go.

[0030] The hydraulic drive device includes a hydraulic push rod 4, the power output end of which passes through the top plate 3 and is connected to the top of the lifting plate 5.

[0031] The hydraulic push rod 4 is connected to an external hydraulic pump and hydraulic oil tank through hydraulic pipelines to ensure that the hydraulic push rod 4 is powered. When the hydraulic push rod 4 is working, it can drive the lifting plate 5 to move in the direction of the placement seat 7, so as to ensure that the metal plate on the placement seat 7 is extruded and sheared into shape.

[0032] Example 2 Based on Embodiment 1, the bottom of the lifting plate 5 is provided with a pressing frame 6, the middle of the pressing frame 6 has a groove 9, and the upper surface of the placement platform is provided with a protrusion 8 that matches the groove 9.

[0033] After the metal plate is positioned by the inclined plate 13, it enters between the two straight plates 12 until it comes into contact with the limiting post 11. At this point, the metal plate is in the optimal shearing position. The hydraulic push rod 4 drives the lifting plate 5 to move towards the placement seat 7. The metal plate is placed on the boss 8 at the top of the placement seat 7. After the extrusion frame 6 at the bottom of the lifting plate 5 contacts the metal plate placed on the top of the boss 8, the lifting plate 5 continues to move downward. Since the groove 9 inside the extrusion frame 6 is the same size as the boss 8, the extrusion and shearing of the metal plate can be achieved, ensuring that the edges and corners of the metal plate are processed into the required shape.

[0034] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations, additions, subtractions, or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
