Description

Technical Field

[0001] The present invention relates to the field of mechanical processing equipment, in particular to a sawing equipment. Background Art

[0002] In the field of batch cutting of metal profiles and pipes, the technology of synchronous cutting of multiple profiles is the key to improving production efficiency. There are many existing devices for achieving synchronous cutting of multiple profiles, but their conveying methods, positioning stability and cutting efficiency still have significant shortcomings.

[0003] A Chinese patent (application number: CN201811489556.6) discloses a dual-saw blade metal cutting machine. This technology uses a dual-saw blade structure to cut two metal pipes at the same time, and the profile is clamped by a main sliding seat and a fixing device.

[0004] The above-mentioned traditional technology has the following problems: it is impossible to realize the continuous progressive feeding of multiple profiles, and can only process a single profile. Multiple profiles need to be repeatedly clamped, resulting in low production efficiency. Summary of the Invention

[0005] Based on this, in order to solve the problem that traditional equipment cannot realize continuous progressive feeding of multiple profiles, can only process single profiles, and multiple profiles need to be repeatedly clamped, resulting in low production efficiency, the present invention provides a sawing device, and its specific technical solution is as follows:

This sawing equipment solves the problem that traditional equipment cannot achieve continuous progressive feeding of multiple profiles, can only process single profiles, and requires repeated clamping of multiple profiles, resulting in low production efficiency.

[0038] In one embodiment, Figures 4-7 As shown, the housing bracket 31 is also provided with auxiliary rollers for supporting the profile. Thus, when the profile is separated from the universal wheel assembly 33, the auxiliary rollers support one end of the profile, while the cutting device 2 supports the other end of the profile, achieving two-point support for the profile, thus preventing the profile from falling.

The first and second connecting bars 324 are hinged to each other, and one of the second swing blocks 325 is connected to each of the universal wheel assemblies 33; the universal wheel assembly 33 includes a rotating wheel 331, a rotating bracket 332, a rotating shaft 333 and a fixed bracket 334; a tray 335 is provided on the housing bracket 31, and the fixed bracket 334 is provided on the tray 335, one end of the rotating shaft 333 is connected to the rotating bracket 332, and the other end of the rotating shaft 333 passes through the fixed bracket 334 and is connected to the first and second connecting bars 324. The two swing blocks 325 are connected, and the rotating wheel 331 is arranged on the rotating bracket 332; the driving mechanism 32 also includes a second driving block 326, a plurality of rollers 327, a plurality of first conveyor belts 328, a plurality of second conveyor belts and a plurality of third conveyor belts 3210; the plurality of rollers 327 are arranged at intervals and are arranged on the outer shell bracket 31, and the plurality of rollers 327 are rotatably connected to the outer shell bracket 31; one of the first conveyor belts 328 is sleeved on one end of two adjacent rollers 327, and one of the second conveyor belts is sleeved on the other end of the second rollers 327. The tray 335 is provided with a plurality of through-holes for the third conveyor belts 3210 to pass through. Multiple third conveyor belts 3210 are sleeved onto the rollers 327. One third conveyor belt 3210 is sleeved onto each rotating wheel 331. One first conveyor belt 328 is sleeved onto the output end of the second drive block 326, which is located on the housing bracket 31 and is used to drive the rollers 327 to rotate. Thus, the rotation of the rotating wheel 331 is controlled by the chain drive of the first drive block 321, the first swing block 322, the first connecting bar 323, and the second connecting bar 324. The rotation of the rotating wheel 331 is driven by the second drive block 326, the rollers 327, and the conveyor belts. The rotation of the rotating wheel 331 prevents scratches on the surface of the profile.

[0040] In one embodiment, Figures 1 to 7As shown, the cutting device 2 includes a cutting mechanism 21, a first cylinder 22 and a cross arm mechanism 23, one end of the cross arm mechanism 23 is connected to the machine 1, the other end of the cross arm mechanism 23 is connected to one end of the first cylinder 22, the other end of the first cylinder 22 is connected to the machine 1, a plurality of air bags 24 are provided on the cross arm mechanism 23, the air bags 24 are hinged to the cross arm mechanism 23, and a plurality of clamping spaces for the profile to pass through are formed between the plurality of air bags 24; the cutting device 2 also includes a plurality of air pumps, and the machine 1 is provided with a channel 5 for the output end of the air pump to pass through; one air pump is connected to one air bag 24; the cross arm mechanism 23 includes a first cross arm 231, a connecting seat 232 and a roller 233; the connecting seat 232 is vertical The vertical direction is arranged on the machine 1, and the connecting seat 232 is provided with a slide rail arranged in a vertical direction. The roller 233 is arranged on the first cross arm 231, and the roller 233 is arranged in the slide rail and is rotatably connected to the slide rail; the first cross arm 231 is connected to the first cylinder 22, and the airbag 24 is hinged to the first cross arm 231; the cross arm mechanism 23 also includes a first rotation drive block, a first threaded rod and a first moving block, the first rotation drive block is arranged on the connecting seat 232, and the first threaded rod is arranged in a vertical direction; one end of the first threaded rod is connected to the output end of the first rotation drive block, and the other end of the first threaded rod passes through the first moving block and is threadedly connected to the first moving block, and the first moving block is arranged on the first cross arm 231. In this way, the first cylinder 22 drives the first cross arm 231 to extend and retract, controlling the clamping space between the airbags 24 and facilitating the adaptation of profiles of varying widths. The hinged connection between the airbags 24 and the first cross arm 231 allows the airbags 24 to dynamically conform to the profile surface during inflation, preventing material damage caused by rigid clamping. The cross arm mechanism 23 and the airbags 24 work together to create multiple flexible clamping spaces. Compared to conventional non-lateral pressure devices, the elastic contact of the airbags 24 evenly distributes the clamping force, avoiding localized stress concentration caused by rigid clamping and thus eliminating the risk of material shifting during sawing. The flexible nature of the airbags 24 allows for adaptive adaptation to varying profile cross-sections, while the controllable air pressure further ensures stable clamping force, preventing deformation caused by excessive compression. Multiple clamping spaces allow for simultaneous clamping of multiple profiles, reducing downtime for reloading. The hinged design of the airbags 24 allows for dynamic adjustment of the clamping space, making it compatible with profiles of varying cross-sectional dimensions (such as special-shaped pipes or variable-section aluminum), eliminating frequent fixture changes.
