Technical Field

[0001] The invention relates to the technical field of shielding tube crimping, in particular to a shielding tube crimping machine. Background Art

[0002] Shielding cylinder is a mechanical protection device used to protect machinery or workers. It can be divided into many types according to its use and shape, such as dustproof cylinder, soundproof cylinder, safety protection cylinder, etc.

[0003] The function of the shielding tube is to isolate sound: in industrial production, the shielding tube can isolate sound, prevent the spread of noise, and protect the health of workers and the environment; dust and shock absorption: the shielding tube can prevent the spread of dust and particles, and protect the safety of machinery and workers. Safety protection: in the production process, the shielding tube can act as a safety protection device to prevent workers from being splashed and hit by mechanical equipment.

[0004] Shielding cylinders are widely used in various industrial fields, especially in places where workers and the environment need to be protected from noise, dust and mechanical damage. For example, installing shielding cylinders in high-speed workshops can effectively prevent workers from being splashed and hit by mechanical equipment, and can further protect the machinery and equipment.

[0005] The function of the metal shielding mesh is to surround the interference source of the components, circuits, cables or the entire system with the metal shielding mesh to prevent the interference electromagnetic field from spreading outward; or to surround the receiving circuit, equipment or system with the metal shielding mesh to prevent them from being affected by the external electromagnetic field. In the production process, the two ports of the metal shielding mesh need to be crimped. At present, various automatic crimping equipment has appeared on the market, but there are few equipments specially used for crimping metal shielding mesh in the prior art, and the working efficiency is low, the degree of automation is not high, and it cannot be used for crimping metal shielding meshes of different sizes.

[0006] In the prior art, the publication number "CN208743437U" discloses an automatic curling machine for a metal shielding mesh cylinder, comprising a frame, a rotating device symmetrically arranged on the frame, and curling devices are arranged on the circumferences of the left and right sets of rotating devices. The rotating device comprises a rotating shaft rotatably mounted on the frame, a turntable arranged at the upper end of the rotating shaft, and a tensioning mechanism arranged on the turntable for tensioning the metal shielding mesh cylinder along the inner side. A motor is installed under the frame, and the motor drives the left and right rotating shafts to rotate; the curling device comprises a guide seat mounted on the frame, a lifting cylinder mounted on the guide seat, a slider 1 slidably mounted on the guide seat in a vertical direction, a horizontal cylinder mounted on the slider 1, a slider 2 slidably mounted on the slider 1 in a horizontal direction, a connecting rod mounted on the slider 2 along the radial direction of the rotating shaft, and a curling wheel vertically arranged at one end of the connecting rod close to the corresponding rotating device, the piston rod of the lifting cylinder is connected to the slider 1, and the piston rod of the horizontal cylinder is connected to the slider 2.

[0007] However, the existing technology still has major deficiencies, such as:

[0008] In the above-mentioned device and the prior art, the operator places the shielding barrel material tube on the surface of the curling table, and then supports the inner cavity of the barrel material tube and rolls the surface of the barrel material tube to achieve curling of the surface of the barrel material tube. During the rolling and curling process of the barrel material tube, it is impossible to pressurize and lock the inside and outside of the bottom end of the barrel material tube. Since the rolling is performed in a rotation cycle, when the rolling pressure on a single end point of the barrel material tube surface is too large, it is easy to cause a rolling depression on the surface of the barrel material tube, affecting the curling effect of the shielding barrel surface.

[0038] An annular anti-skid rubber ring 14 is arranged at the bottom of the placement cavity 12, and the annular anti-skid rubber ring 14 is arranged in a plurality of groups at intervals.

[0039] The bottom layer pressurizing support unit of the cylinder curling is arranged on the surface area of ​​the center platform 3, and is used to pressurize and support the inner cavity of the shielding cylinder to reduce the rotation displacement of the shielding cylinder during the curling process;

[0040] The bottom layer pressurizing support unit of the cylinder curling includes a bottom support part, which includes a central sleeve 5, which is installed in the central area of ​​the central platform 3.

[0041] The bottom layer pressurized support unit of the cylinder curling also includes a top support part, which includes a lifting hydraulic cylinder 6, which is installed in the inner cavity of the central sleeve 5. A support platform 61 is arranged on the top of the lifting hydraulic cylinder 6, and a heightening column 7 is installed on the top of the support platform 61.

The top hydraulic cylinder 73 is arranged in several groups, and a top support block 74 is installed on the movable end of the top hydraulic cylinder 73, and a top anti-slip pad 75 is embedded in the surface of the top support block 74.

[0042] In this embodiment, the top support block 74 is pressed against the top surface area of ​​the shielding tube material tube after continuous expansion, thereby forming an inner cavity support for the rolling area outside the top of the inner cavity of the shielding tube material tube, thereby avoiding the problem of excessive single-point pressure on the top of the shielding tube material tube surface during the rolling process, and ensuring the rolling treatment effect of the top surface of the shielding tube material tube. The bottom support block 54 is pressed against the bottom surface area of ​​the shielding tube material tube after continuous expansion, thereby forming an inner cavity support for the rolling area outside the bottom of the inner cavity of the shielding tube material tube, thereby avoiding the problem of excessive single-point pressure on the bottom of the shielding tube material tube surface during the rolling process, and ensuring the rolling treatment effect of the bottom surface of the shielding tube material tube.

[0043] The cylinder surface curling and pressurizing molding unit is arranged on the surface area of ​​the curling frame 2 and is used for performing pressurizing and curling processing on the surface position of the shielding cylinder;

[0044] The cylinder surface curling and pressurizing forming unit includes a top pressurizing part, which includes a top frame 211. A top groove 21 is provided on one side of the curling frame 2. The top frame 211 is installed on one side of the top groove 21. A top telescopic cylinder 212 is installed on one side of the top frame 211.

[0046] The cylinder surface curling and pressurizing unit also includes a driving part, which includes an annular guide frame 8, which is installed at the bottom of the curling base 1, and the bottom of the curling frame 2 is installed at the top of the rotating end of the annular guide frame 8.

[0047] In this embodiment, the top area or the bottom area of ​​the shielding tube surface can be roll-formed by selecting the top rolling wheel 214 or the bottom rolling wheel 224 in the top frame 211 or the bottom frame 221 area, and at the same time, the annular guide frame 8 can be driven to drive the curling frame 2 to rotate and roll, thereby ensuring the curling treatment of the shielding tube surface.

[0048] Embodiment 2:

[0049] Based on the first embodiment, in this embodiment, it is considered that when rolling the bottom of the shielding tube material tube surface, a double-layer bottom roller 224 is usually used for double-layer curling. When the double-layer bottom roller 224 is curling, the bottom of the shielding tube material tube surface will be too large, which may easily cause the shielding tube material tube to slide inside the placement cavity 12, resulting in the shielding tube material tube surface rolling curling deviation, affecting the shielding tube material tube surface rolling curling effect, so in this embodiment, the inner and outer side pressure locking units at the bottom of the cylinder are provided to avoid the above problems;

[0050] The surface of the center platform 3 is provided with an installation cavity 31, the inner wall of the circular cavity 11 is provided with a side groove 13, the installation cavity 31 and the side groove 13 are arranged in several groups at intervals, and the installation cavity 31 and the side groove 13 area are provided with inner and outer side pressure locking units at the bottom of the cylinder.

[0051] The inner and outer side pressurized locking unit at the bottom end of the cylinder includes an inner locking part, which includes a built-in cylinder 32. The built-in cylinder 32 is installed inside the installation cavity 31. A built-in pressure block 33 is slidably arranged inside the installation cavity 31. The built-in pressure block 33 is installed on the moving end of the built-in cylinder 32. A non-slip rubber belt 34 is arranged inside the installation cavity 31, and the built-in pressure block 33 is in active contact with the non-slip rubber belt 34.

[0052] The inner and outer pressurized locking unit at the bottom of the cylinder also includes an external locking part, which includes an external cylinder 4 installed inside the side slot 13. An external rubber block 41 is installed on the movable end of the external cylinder 4, and the external rubber block 41 is in active contact with the outer surface of the shielding cylinder.

[0053] In this embodiment, the external cylinder 4 installed inside the side slot 13 will also drive the external rubber block 41 to move and fit into the corresponding position on the outer wall surface of the shielding tube material tube, thereby completing the pressurized locking of the inner and outer sides of the bottom of the shielding tube material tube, ensuring the stability of the bottom of the shielding tube material tube during the double-layer curling process, and further ensuring the rolling treatment effect of the bottom surface of the shielding tube material tube.

[0054] Working principle: During the use of this device, the operator first calibrates the center of the shielding tube material tube and places it in the placement cavity 12 outside the center platform 3. The bottom of the placement cavity 12 is provided with multiple sets of annular anti-skid rubber rings 14. The annular anti-skid rubber rings 14 will fit the bottom of the shielding tube material tube to reduce the movable displacement of the shielding tube material tube during the rolling process. When the shielding tube material tube is placed in place, the operator can roll the top area or bottom area of ​​the shielding tube material tube surface by selecting the top rolling wheel 214 or the bottom rolling wheel 224 in the top frame 211 or the bottom frame 221 area, and at the same time, the annular guide frame 8 can be driven to drive the curling frame 2 to rotate and roll to ensure the curling treatment of the shielding tube material tube surface;

[0055] Before the operator performs roll forming processing on the top area of ​​the shielding tube material tube surface by the top rolling wheel 214, the support platform 61 can be lifted vertically by driving the lifting hydraulic cylinder 6. When the support platform 61 reaches the top rolling area, the top hydraulic cylinder 73 installed inside the top positioning block 71 is driven to move, and the moving end of the top hydraulic cylinder 73 drives the top support block 74 to move outward and expand. After continuous expansion, multiple groups of top support blocks 74 are pressed tightly against the top surface area inside the shielding tube material tube, thereby forming an inner cavity support for the rolling area outside the top of the inner cavity of the shielding tube material tube, thereby avoiding the problem of excessive single-point pressure on the top of the shielding tube material tube surface during the rolling process, and ensuring the rolling processing effect of the top of the shielding tube material tube surface;

[0056] Before the operator performs roll forming processing on the bottom area of ​​the shielding tube material tube surface through the bottom reel 224, the bottom hydraulic cylinder 53 installed inside the bottom positioning block 51 can be driven to move, and the moving end of the bottom hydraulic cylinder 53 drives the bottom support block 54 to move outward and expand. After continuous expansion, multiple groups of bottom support blocks 54 are pressed against the bottom surface area of ​​the shielding tube material tube, thereby forming an inner cavity support for the rolling area outside the bottom of the inner cavity of the shielding tube material tube, thereby avoiding the problem of excessive single-point pressure on the bottom of the shielding tube material tube surface during the rolling process, and ensuring the rolling processing effect of the bottom of the shielding tube material tube surface;

[0057] When rolling the bottom of the shielding tube surface, a double-layer bottom reel 224 is usually used for double-layer curling. When the double-layer bottom reel 224 is curling, the bottom of the shielding tube surface will be too large, which may easily cause the shielding tube to slide inside the placement cavity 12. Therefore, the built-in cylinder 32 installed in the mounting cavity 31 at the top of the center platform 3 can be moved outward and extended. The moving end of the built-in cylinder 32 will move outward with the built-in pressure block 33 to unfold. The built-in pressure block 33 will push the anti-slip rubber belt 34 to move outward during the movement and unfolding process until the anti-slip rubber belt 34 is pushed and fit to the bottom surface of the inner wall of the shielding tube by the built-in pressure block 33. At the same time, the external cylinder 4 installed in the side slot 13 will also drive the external rubber block 41 to move and fit to the corresponding position of the outer wall surface of the shielding tube, thereby completing the pressurized locking of the inside and outside of the bottom of the shielding tube, ensuring the stability of the bottom of the shielding tube during the double-layer curling process, and further ensuring the rolling treatment effect of the bottom of the shielding tube surface.

[0058] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
