Description

Technical Field

[0001] This utility model relates to the field of profile processing technology, and in particular to a device for removing waste material from the cavity of a profile by stamping. Background Technology

[0002] Profiles refer to strip materials with a certain geometric shape that are processed through rolling, extrusion, casting and other processes. They are usually made of iron, steel or other metals. The cross-sectional shape and size of profiles are strictly regulated, such as I-beams and angle steel. They can be used directly or further processed into other products. They are commonly used in building structures, machinery manufacturing and other fields. According to the material and processing method, they can be divided into metal profiles and non-metal profiles.

[0003] During the processing of profiles, burrs or lint are easily generated on the surface due to friction from cutting or stamping. These profile parts with burrs or lint need to be reworked to smooth out these defects. The grinding method is usually machine grinding by workers. However, in the rework of some profiles with internal cavities, the machining tools are difficult to penetrate into the internal cavity of the profile, and the field of vision inside the cavity is poor, making it difficult to observe the grinding situation inside the profile cavity. This results in extremely low efficiency of machine grinding. Utility Model Content

[0004] To overcome the problem that machining tools are difficult to penetrate into the inner cavity of profiles with internal cavities during rework, and that the field of vision inside the inner cavity is poor, making it difficult to observe the grinding situation inside the profile, thus resulting in extremely low machining and grinding efficiency.

[0005] The technical solution of this utility model is as follows: a waste removal device for profile cavity stamping, including a base plate and telescopic guide rods, as well as an upper die and a punch. The telescopic guide rods are fixedly installed at the four corners of the upper end of the base plate. The upper die is fixedly connected to the upper end of the telescopic guide rods. The punch is fixedly installed at the lower end of the upper die. A pressure plate for fixing the profile is fixedly connected to the end of the punch. A die for cleaning the inner cavity of the profile is provided at the lower end of the punch. A push block for driving the die to move is provided at the upper end of the base plate.

[0006] Preferably, a spring is fitted on the surface of the punch, and a guide shaft is fixedly connected to the lower end of the upper die. The guide shaft is slidably connected to the pressure plate, and the spring is used to press down the pressure plate.

[0007] Preferably, the pressure plate has openings on both sides of its surface, and guide shafts are fixedly installed on both sides of the upper end of the pressure plate. A push plate is slidably connected to the surface of the guide shafts, and the die mold is fixedly installed on one side of the push plate by bolts.

[0008] Preferably, a roller is rotatably connected to the lower end of the push plate, a standard cylinder is fixedly installed at the lower end of the base plate, and a push block is fixedly installed at the upper end of the output end of the standard cylinder.

[0009] Preferably, the upper end of the push block is an inclined surface, the roller shaft contacts the upper inclined surface of the push block, a standard cylinder is fixedly installed at the lower end of the base plate, a movable plate is fixedly installed at the output end of the standard cylinder, and a support block is provided on one side of the movable plate for positioning.

[0010] Preferably, a guide shaft three is fixedly installed at the lower end of the base plate, the guide shaft three is slidably connected to the movable plate, the surface of the movable plate is provided with an opening, and the push block is located in the opening on the surface of the movable plate.

[0011] Preferably, a limiting strip is fixedly connected to the upper end of the base plate. The upper end of the limiting strip has rounded corners. The limiting strip contacts both sides of the bottom end of the profile, and the support block contacts one side of the bottom of the profile.

[0012] The beneficial effects of this utility model are:

[0013] 1. After the profile is positioned, the waste material stamping and removal device in the profile cavity starts the standard cylinder two. The inclined surface at the upper end of the push block passes through the extrusion roller shaft, causing the die mold fixed on one side of the push plate to move to one side and enter the inner cavity of the profile, thereby completing the grinding of the inner cavity of the profile and quickly removing the waste material in the inner cavity, greatly improving efficiency.

[0014] 2. When using, first place the profile on the top of the base plate. As the punch moves downward, the pressure plate presses the top of the profile, thus initially fixing the profile. After the pressure plate initially fixes the profile, start the standard cylinder one. The support block supports and positions the bottom side of the profile, and the limit strip limits and fixes both sides of the profile. The profile positioning is quick and convenient, further improving efficiency. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figure 1 - Figure 5 This utility model provides an embodiment of a profile cavity waste removal device by stamping, which includes a base plate 1 and a telescopic guide rod 2, as well as an upper die 3 and a punch 4. The telescopic guide rod 2 is fixedly installed at the four corners of the upper end of the base plate 1. The upper die 3 is fixedly connected to the upper end of the telescopic guide rod 2. The punch 4 is fixedly installed at the lower end of the upper die 3. The end of the punch 4 is fixedly connected to a pressure plate 5 for fixing the profile. The lower end of the punch 4 is provided with a concave die 11 for cleaning the inner cavity of the profile. The upper end of the base plate 1 is provided with a push block 18 for driving the concave die 11 to move. After the profile is positioned, the inclined surface provided at the upper end of the push block 18 causes the concave die 11 fixedly installed on one side of the push plate 9 to move to one side and enter the inner cavity of the profile by pressing, thereby completing the grinding of the inner cavity of the profile and quickly removing the waste in the inner cavity, greatly improving efficiency.

[0023] Please see Figure 4 and Figure 5In this embodiment, a spring 6 is sleeved on the surface of the punch 4. A guide shaft 7 is fixedly connected to the lower end of the upper die 3. The guide shaft 7 is slidably connected to the pressure plate 5. The spring 6 is used to press down the pressure plate 5. Openings are provided on both sides of the surface of the pressure plate 5. A guide shaft 8 is fixedly installed on both sides of the upper end of the pressure plate 5. A push plate 9 is slidably connected to the surface of the guide shaft 8. The die mold 11 is fixedly installed on one side of the push plate 9 by bolts. A roller shaft 10 is rotatably connected to the lower end of the push plate 9. A standard cylinder 17 is fixedly installed on the lower end of the base plate 1. A push block 18 is fixedly installed on the upper end of the output end of the standard cylinder 17. In use, the profile is first placed on the upper end of the base plate 1, and then the hydraulic system is used to lower the upper die 3. The upper die 3 lowers simultaneously with the lower die 3. The punch 4 moves downwards, and the telescopic guide rod 2 is used to ensure the stability of the punch 4's movement. The pressure plate 5 presses the upper end of the profile, thus initially fixing the profile. The guide shaft 7 is used to ensure the stability of the pressure plate 5's movement. After the profile is processed, the pressure plate 5 is reset by the spring 6. After the profile is positioned, the standard cylinder 17 is started. The standard cylinder 17 drives the push block 18 to move upwards. During the upward movement of the push block 18, the inclined surface at the upper end of the push block 18 presses the roller shaft 10 at the lower end of the push plate 9, causing the push plate 9 to move to one side. At the same time, the die 11 fixedly installed on one side of the push plate 9 moves to one side and enters the inner cavity of the profile, thus completing the grinding of the inner cavity of the profile and removing the waste material from the inner cavity.

[0024] Please see Figure 2 and Figure 4 In this embodiment, the upper end of the push block 18 is an inclined surface, and the roller shaft 10 contacts the inclined surface of the upper end of the push block 18. A standard cylinder 12 is fixedly installed at the lower end of the base plate 1, and a movable plate 13 is fixedly installed at the output end of the standard cylinder 12. A support block 14 is provided on one side of the movable plate 13 for positioning. A guide shaft 16 is fixedly installed at the lower end of the base plate 1, and the guide shaft 16 is slidably connected to the movable plate 13. An opening is provided on the surface of the movable plate 13, and the push block 18 is located in the opening on the surface of the movable plate 13. A limit strip 15 is fixedly connected to the upper end of the base plate 1. The upper end of the profile is rounded. The limiting strip 15 contacts the bottom two sides of the profile, and the support block 14 contacts the bottom one side of the profile. After the pressure plate 5 initially fixes the profile, the standard cylinder 12 is activated, and the moving plate 13 moves upward. The support block 14 on one side of the moving plate 13 supports and positions the bottom one side of the profile. The limiting strip 15 limits and fixes the two sides of the profile, thus completing the positioning of the profile. The upper end of the limiting strip 15 is rounded to prevent the limiting strip 15 from damaging the surface of the profile when the profile is placed on the upper end of the base plate 1. The guide shaft 16 is used to ensure the stability of the movement of the moving plate 13.

[0025] In use, the profile is first placed on the upper end of the base plate 1. Then, the hydraulic system lowers the upper die 3. As the upper die 3 lowers, it drives the punch 4 to move downward. The telescopic guide rod 2 is used to ensure the stability of the punch 4. During the downward movement of the punch 4, the pressure plate 5, which is slidably connected to the surface of the punch 4, presses the upper end of the profile, thereby initially fixing the profile. The guide shaft 7 is used to ensure the stability of the pressure plate 5. After the profile is processed, the pressure plate 5 is reset by the spring 6.

[0026] After the pressure plate 5 initially fixes the profile, the standard cylinder 12 is activated. The standard cylinder 12 drives the moving plate 13 to move upward. The support block 14 on one side of the moving plate 13 supports and positions the bottom side of the profile. The limiting strip 15 limits and fixes the two sides of the profile, thus completing the positioning of the profile. The upper end of the limiting strip 15 is rounded to prevent the limiting strip 15 from damaging the surface of the profile when the profile is placed on the upper end of the base plate 1. The guide shaft 16 is used to ensure the stability of the movement of the moving plate 13.

[0027] After the profile is positioned, standard cylinder 17 is activated. Standard cylinder 17 drives push block 18 to move upward. During the upward movement of push block 18, the inclined surface at the upper end of push block 18 presses the roller 10 at the lower end of push plate 9, causing push plate 9 to move to one side. At the same time, the concave mold 11 fixedly installed on one side of push plate 9 moves to one side and enters the inner cavity of profile, thereby completing the grinding of the inner cavity of profile and removing the waste material in the inner cavity. Guide shaft 28 is used to ensure the stability of push plate 9 movement.

[0028] Through the above steps, after the profile is positioned, the waste material stamping and removal device in the profile cavity starts the standard cylinder 17. The inclined surface at the upper end of the push block 18 passes through the extrusion roller shaft 10, causing the die 11 fixedly installed on one side of the push plate 9 to move to one side and enter the inner cavity of the profile, thereby completing the grinding of the inner cavity of the profile and quickly removing the waste material in the inner cavity, greatly improving efficiency.
