Hydraulic cutting apparatus for aluminum products

Abstract

This utility model relates to the field of hydraulic cutting equipment technology, specifically to a hydraulic cutting equipment for aluminum products. It includes a hydraulic cutting equipment body with two support frames mounted on its left side. An electric push rod is mounted on the top of each support frame, and a lower pressure plate is fixedly connected to the output end of the electric push rod. Slide rods are inserted into both sides of the support frames, with a fixing plate mounted on the top of each slide rod. A spring is sleeved on the lower outer side of each slide rod. When the electric push rod drives the lower pressure plate downwards to fix the aluminum product, the compression and contraction of the springs on both sides creates a buffering effect, thereby attenuating the dynamic load transmitted to the clamp during the cutting process. Simultaneously, the rubber protrusions at the bottom of the connecting plate enhance the positioning stability of the aluminum product and further absorb impact energy through elastic deformation, thereby improving the operational stability and processing quality of the hydraulic cutting equipment.

Description

Technical Field

[0001] This utility model relates to the field of hydraulic cutting equipment technology, and more specifically, to a hydraulic cutting equipment for aluminum products. Background Technology

[0002] Aluminum materials are widely used in automobile manufacturing, building decoration and electronic appliances due to their lightweight, corrosion resistance and excellent electrical and thermal conductivity. With the continuous development of industrial technology, the requirements for cutting precision, efficiency and surface quality in aluminum product processing are increasing.

[0003] A search revealed a prior art hydraulic cutting device for aluminum profiles, patent publication number CN217343773U. The specification describes a base with multiple sliding support frames. Each support frame has two opposing clamping devices for clamping the aluminum profile. The cutting mechanism is mounted on a truss, with its lower end slidably connected to the base. Once the workpiece is clamped, the truss drives the cutting mechanism to move on the base, automatically cutting the workpiece without requiring manual hand-held operation. This effectively improves processing efficiency and accuracy, ensuring the quality of the processed aluminum profile.

[0004] However, in actual use, although the above-mentioned hydraulic cutting equipment does not require workers to hold the cutting machine and can improve processing efficiency and processing accuracy, the large downward impact force generated when the hydraulic cylinder cuts aluminum products directly affects the service life of the fixture. Due to the lack of an effective buffer mechanism, this impact not only shortens the service life of the fixture and affects its performance, but also reduces the overall working performance of the hydraulic cutting equipment. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a hydraulic cutting device for aluminum products to solve the problem that the lack of an effective buffer mechanism in the prior art not only leads to a shortened service life of the clamp and affects its performance, but also reduces the overall working performance of the hydraulic cutting device.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a hydraulic cutting device for aluminum products, including a hydraulic cutting device body, two support frames are installed on the left side of the hydraulic cutting device body, an electric push rod is installed on the top of the support frame, a lower pressure plate is fixedly connected to the output end of the electric push rod, slide rods are inserted into both the left and right sides of the support frame, a fixing plate is installed at the top of the slide rod, a spring is sleeved on the lower outer side of the slide rod, an insertion groove is opened in the lower part of the lower pressure plate, a connecting plate is inserted into the inner wall of the insertion groove, and multiple rubber protrusions are installed at the bottom of the connecting plate.

[0007] The upper part of the slide rod is provided with a threaded part, and a threaded knob is threadedly connected to the outer side of the threaded part.

[0008] The bottom of the threaded knob is attached to the top of the spring.

[0009] The front and rear pressure plates each have a moving groove in the middle of their opposite sides. A moving block is slidably connected to the inner wall of the moving groove. A fixing rod is inserted into the middle of the moving block. An elastic element is sleeved on the outside of the fixing rod. A limiting plate is installed at the bottom of the moving block. A limiting groove is also provided on the top of the front and rear connecting plates on their opposite sides.

[0010] The upper and lower ends of the fixed rod are installed between the inner wall of the moving groove, and the opposite sides of the moving blocks on the front and rear sides are penetrated by the lower pressure plate.

[0011] One end of the elastic element is installed between the inner top wall of the moving groove and the other end is installed between the top of the moving block.

[0012] The limiting plate penetrates the inner top wall of the insertion slot, and its lower part is inserted into the inner wall of the limiting slot.

[0013] The bottom end of the slide rod is installed on the top of the lower pressure plate, the output end of the electric push rod passes through the support frame, the spring is compressed by the threaded knob, and the bottom end of the spring is attached to the top of the support frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In the above scheme, when the pressure plate moves down to fix the aluminum product under the drive of the electric push rod, the compression and contraction of the springs on both sides form a buffer effect, thereby attenuating the dynamic load transmitted to the fixture during the cutting process. At the same time, the rubber protrusions set at the bottom of the connecting plate not only enhance the positioning stability of the aluminum product, but also absorb the impact energy through elastic deformation, thereby improving the smooth operation and processing quality of the hydraulic cutting equipment.

Detailed Implementation

[0023] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0024] Example 1: Please refer to Figures 1 to 5 This utility model provides a technical solution: a hydraulic cutting device for aluminum products, including a hydraulic cutting device body 1. Two support frames 2 are installed on the left side of the hydraulic cutting device body 1. An electric push rod 3 is installed on the top of the support frame 2. A lower pressure plate 9 is fixedly connected to the output end of the electric push rod 3. Slide rods 8 are inserted into both the left and right sides of the support frame 2. A fixing plate 4 is installed at the top of the slide rod 8. The fixing plate 4 serves as a limit to prevent the threaded knob 6 from disengaging from the threaded part 5. A spring 7 is sleeved on the lower outer side of the slide rod 8. An insertion groove 12 is opened in the lower part of the lower pressure plate 9. A connecting plate 1 is inserted into the inner wall of the insertion groove 12. 0. Multiple rubber protrusions 11 are installed at the bottom of the connecting plate 10. The bottom end of the slide rod 8 is installed at the top of the lower pressure plate 9. The output end of the electric push rod 3 passes through the support frame 2. When the electric push rod 3 drives the lower pressure plate 9 to press down and fix the aluminum product, the rubber protrusions 11 deform to absorb the impact force caused by the hydraulic cutting equipment body 1 during cutting, thereby weakening the impact on the clamp. The spring 7 is compressed by the threaded knob 6 and the bottom end of the spring 7 is attached to the top of the support frame 2. Thus, the spring 7 forms a buffer in the compressed state to reduce the impact force on the clamp.

[0025] In use, the aluminum product is first placed on the processing table. Then, the two electric push rods 3 are activated to push the lower pressure plate 9 downward to press and fix the aluminum product. During this process, the slide rod 8 moves downward synchronously. Due to the setting of the threaded knob 6, the spring 7 is pushed downward and compressed at the top of the support frame 2. At the same time, when the lower pressure plate 9 presses down to fix the aluminum product, the rubber protrusion 11 will contact the aluminum product first and gradually become elastically deformed as the lower pressure plate 9 moves downward. Then, the hydraulic cutting equipment body 1 can perform cutting operations on the aluminum product. During cutting, the rubber protrusion 11 absorbs the impact force caused by the hydraulic cutting equipment body 1 during cutting, and the spring 7 is used for buffering, thereby reducing the impact force on the fixture, thus improving the service life of the fixture, and further improving the use effect of the hydraulic cutting equipment body 1.

[0026] Example 2: Based on Example 1, in order to facilitate the adjustment of the tension of the spring 7, the upper part of the slide bar 8 is provided with a threaded part 5. A threaded knob 6 is threadedly connected to the outer side of the threaded part 5. The bottom of the threaded knob 6 is attached to the top of the spring 7. By rotating the threaded connection between the threaded knob 6 and the threaded part 5, the spring 7 can be moved up or down, thereby adjusting the tension of the spring 7 on the outer side of the slide bar 8, so as to meet the usage needs of different users.

[0027] When the user needs to adjust the tension of the spring 7, they can directly rotate the threaded knob 6 to move it up or down along the outside of the threaded part 5, so that the spring 7 is compressed downward or reset upward. In this way, the tension of the spring 7 can be adjusted according to the user's needs to suit the usage requirements of different users.

[0028] Example 3: Based on Example 2, to facilitate the replacement of the rubber protrusion 11, a moving groove 14 is provided in the middle of the opposite side of the front and rear pressure plates 9. A moving block 17 is slidably connected to the inner wall of the moving groove 14. A fixing rod 15 is inserted into the middle of the moving block 17. An elastic element 16 is sleeved on the outer side of the fixing rod 15. A limiting plate 18 is installed at the bottom of the moving block 17. A limiting groove 13 is provided in the top of the front and rear connecting plates 10 on the opposite side. The upper and lower ends of the fixing rod 15 are installed between the inner wall of the moving groove 14. In order to increase the stability of the moving block 17 during the movement of the moving block 17 in the inner wall of the moving groove 14, the opposite side of the front and rear moving blocks 17 is provided with a limiting groove 13. The lower pressure plate 9 is penetrated, and the moving block 17 is pushed upward to slide along the moving groove 14, causing the lower part of the limiting plate 18 to disengage from the limiting groove 13, thereby facilitating the removal of the connecting plate 10 for replacement of the rubber protrusion 11. One end of the elastic member 16 is installed between the inner top wall of the moving groove 14 and the other end is installed between the top of the moving block 17, thereby using the elastic force of the elastic member 16 to keep the lower part of the limiting plate 18 always inserted with the limiting groove 13 for subsequent disassembly and assembly. The limiting plate 18 penetrates the inner top wall of the insertion groove 12 and the lower part is inserted into the inner wall of the limiting groove 13, thereby facilitating the fitting between the connecting plate 10 and the lower pressure plate 9 and facilitating subsequent disassembly and assembly.

[0029] When maintenance of the rubber protrusion 11 is required, first move the moving block 17 upwards, simultaneously causing the limiting plate 18 at its bottom to disengage from the limiting groove 13. As the moving block 17 slides upwards along the inner wall of the moving groove 14, it will squeeze the elastic element 16 sleeved on the outside of the fixed rod 15, gradually compressing it. At this time, the connecting plate 10 can be pulled out of the insertion groove 12 to remove the rubber protrusion 11 for replacement. After completion, reset the connecting plate 10 and insert it into the inner wall of the insertion groove 12. At the same time, move the moving block 17 upwards. When the connecting plate 10 is fully inserted into the inner wall of the insertion groove 12, release the moving block 17. The elastic force of the elastic element 16 will then push the moving block 17 downwards along the inner wall of the moving groove 14 to reset it, thereby causing the limiting plate 18 to insert into the inner wall of the limiting groove 13, thus locking the connecting plate 10 and the lower pressure plate 9. This facilitates the maintenance and replacement of the rubber protrusion 11 in the future, thereby improving the performance of the hydraulic cutting equipment body 1.

[0030] The working process of this utility model is as follows:

[0031] In use, the aluminum product is first placed on the processing table. Then, the two electric push rods 3 are activated to push the lower pressure plate 9 downward to press and fix the aluminum product. During this process, the slide rod 8 moves downward synchronously. Due to the setting of the threaded knob 6, the spring 7 is pushed downward and compressed at the top of the support frame 2. At the same time, when the lower pressure plate 9 presses down to fix the aluminum product, the rubber protrusion 11 will contact the aluminum product first and gradually become elastically deformed as the lower pressure plate 9 moves downward. Then, the hydraulic cutting equipment body 1 can perform cutting operation on the aluminum product. During cutting, the rubber protrusion 11 absorbs the impact force caused by the hydraulic cutting equipment body 1 during cutting, and the spring 7 is used for buffering, thereby reducing the impact force on the fixture, thus improving the service life of the fixture, and further improving the use effect of the hydraulic cutting equipment body 1.

[0032] When the user needs to adjust the tension of the spring 7, he can directly rotate the threaded knob 6 to move it up or down along the outside of the threaded part 5, so that the spring 7 is compressed downward or reset upward. In this way, the tension of the spring 7 can be adjusted according to the user's needs to suit the usage needs of different users.

[0033] When maintenance of the rubber protrusion 11 is required, first move the moving block 17 upwards, simultaneously causing the limiting plate 18 at its bottom to disengage from the limiting groove 13. As the moving block 17 slides upwards along the inner wall of the moving groove 14, it will squeeze the elastic element 16 sleeved on the outside of the fixed rod 15, gradually compressing it. At this time, the connecting plate 10 can be pulled out of the insertion groove 12 to remove the rubber protrusion 11 for replacement. After completion, reset the connecting plate 10 and insert it into the inner wall of the insertion groove 12. At the same time, move the moving block 17 upwards. When the connecting plate 10 is fully inserted into the inner wall of the insertion groove 12, release the moving block 17. The elastic force of the elastic element 16 will then push the moving block 17 downwards along the inner wall of the moving groove 14 to reset it, thereby causing the limiting plate 18 to insert into the inner wall of the limiting groove 13, thus locking the connecting plate 10 and the lower pressure plate 9. This facilitates the maintenance and replacement of the rubber protrusion 11 in the future, thereby improving the performance of the hydraulic cutting equipment body 1.
