Abstract
Description
Technical Field

[0020] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present utility model and should not be construed as limiting the present utility model.
[0021] The crawler-type traction extrusion forming integrated device according to the embodiments of the present utility model will be described below with reference to the drawings.
[0022] AsFigure 1 , 2 As shown in 2 , an embodiment of the utility model provides a crawler-type traction extrusion forming integrated device, which includes: an upper crawler 1, a lower crawler 8, an upper clamping block 4 and a lower clamping block 6. A number of support blocks 2 are detachably and fixedly connected to the outer sides of the upper crawler 1 and the lower crawler 8 respectively. The upper crawler 1 is located above the lower crawler 8. The upper crawler 1 and the lower crawler 8 are respectively driven by a driving device to traction the profile 5 to be extruded. A plurality of extrusion wheels are respectively arranged inside the upper crawler 1 and the lower crawler 8, and the extrusion wheels are in close contact with the inner side surfaces of the upper crawler 1 and the lower crawler 8 respectively; the upper clamping block 4 is detachably and fixedly connected to the outer side of each support block 2 of the upper crawler 1, and the outer side of the upper clamping block 4 has an upper extrusion module 3; the lower clamping block 6 is detachably and fixedly connected to the outer side of each support block 2 of the lower crawler 8, and the outer side of the lower clamping block 6 has a lower extrusion module 7. The position of the lower extrusion module 7 corresponds to that of the upper extrusion module 3, and a channel for passing through the profile 5 to be extruded is left between the lower extrusion module 7 and the upper extrusion module 3.
[0023] In the embodiment of the utility model, by setting the upper clamping block 4 and the lower clamping block 6, the profile is made into the required cross-section by the extrusion of the upper clamping block 4 and the lower clamping block 6. By setting the upper crawler 1 and the lower crawler 8, the contact surfaces of the upper extrusion module 3, the lower extrusion module 7 and the profile 5 to be extruded are extended, which is more conducive to the forming of the profile. Moreover, the profile can be normally traction without a large clamping force, and the profile will not be split or deformed due to the influence of the clamping force. The traction speed is more stable without jerks, ensuring the stability of the product appearance. By designing the upper clamping block 4 and the lower clamping block 6 in a detachable connection manner, rapid disassembly and assembly are realized, so that the upper clamping block 4 and the lower clamping block 6 can be replaced with the required shapes, and profiles with various complex cross-sections can be processed, with strong versatility.
[0024] It should be noted that the upper crawler 1 and the lower crawler 8 are respectively driven by their respective driving devices, and the moving speeds of the upper crawler 1 and the lower crawler 8 are synchronized. Specifically, the driving device is a driving wheel and a reducer. The driving wheel is arranged inside the crawler, and the connection manner between the driving wheel and the crawler can be a gear-rack connection manner. The output end of the reducer is connected to the driving wheel to drive the driving wheel to rotate, and then drive the crawler to rotate. The driving wheel is usually arranged on one side inside the crawler. The extrusion wheels arranged inside the upper crawler 1 and the lower crawler 8 are used to increase the extrusion force on the profile, so that the profile can be quickly formed. Specifically, the extrusion wheel is in close contact with the crawler, and the connection manner between the extrusion wheel and the crawler can be a gear-rack connection manner.
[0025] In some embodiments, one of the upper extrusion module 3 and the lower extrusion module 7 is a convex module, and the other is a concave module. The convex module and the concave module cooperate with each other to extrude and form the profile.
[0026] Furthermore, the upper extrusion module 3 is a concave module, and the lower extrusion module 7 is a convex module.
[0027] In some embodiments, the upper extrusion module 3 is located in the middle of the upper clamping block 4, and the lower extrusion module 7 is located in the middle of the lower clamping block 6. The force is concentrated at the middle position of the clamping block, which is convenient for the rapid forming of the profile.
[0028] In some alternative embodiments, two or more upper extrusion modules 3 are evenly arranged on each upper clamping block 4, and two or more lower extrusion modules 7 are evenly arranged on each lower clamping block 6. It is possible to simultaneously extrude and form two or more profiles.
[0029] In some embodiments, both the upper clamping block 4 and the lower clamping block 6 are made of polyurethane. The polyurethane material has a certain ductility, which allows the profile to pass smoothly through the gap between the upper clamping block 4 and the lower clamping block 6, and extrudes and forms the profile while the profile passes through.
[0030] In some embodiments, the upper clamping block 4 and the support block 2 of the upper track 1 are fixedly connected by bolts, and the lower clamping block 6 and the support block 2 of the lower track 8 are fixedly connected by bolts. This makes the disassembly and assembly of the upper clamping block 4 and the lower clamping block 6 convenient and facilitates replacement.
[0031] In some embodiments, the support block 2 is fixedly connected to the upper track 1 or the lower track 8 through a clamping member 9. The clamping member 9 provides a clamping force to the support block 2, making the fixation of the support block 2 more firm and preventing it from loosening or falling during the operation of the track.
[0032] In some embodiments, as Figure 2 shown, the clamping member 9 has a C-shaped structure. The bottom of the clamping member 9 is fixedly connected to the outside of the upper track 1 or the outside of the lower track 8. Both sides of each support block 2 are clamped and fixed by at least two clamping members 9 respectively, and the upper part of the clamping member 9 and the support block 2 are fixedly connected by bolts. This is convenient for the quick disassembly and assembly of the support block 2 and facilitates the replacement of the damaged support block 2.
[0033] In some embodiments, the support block 2 is rectangular in shape and the material of the support block 2 is metal. Using a support block 2 made of metal can increase the extrusion force of the clamping block on the profile.
[0034] Furthermore, the material of the support block 2 is a hard metal material such as cast iron or stainless steel.
[0035] In some embodiments, as Figure 2 shown, corner slots 10 are respectively formed on both sides of the upper end and both sides of the lower end of the support block 2 to insert the upper and lower parts of the clamping member 9 respectively.
