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 devices in the prior art that can achieve synchronous cutting of multiple profiles, but their conveying methods, positioning stability and cutting efficiency still have significant defects.

[0003] A Chinese patent (application number: CN201811489556.6) discloses a double-saw blade metal cutting machine, which uses a double-saw blade structure to cut two metal pipes at the same time, and achieves profile clamping through 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 clamped repeatedly, resulting in low production efficiency. Summary of the invention

[0005] Based on this, in order to solve the problem that the traditional equipment cannot realize the continuous progressive feeding of multiple profiles, can only process a single profile, 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: A sawing device comprising Machine; Cutting device; An auxiliary device, the auxiliary device comprises a housing bracket, a driving mechanism and a plurality of universal wheel assemblies, the driving mechanism and the plurality of universal wheel assemblies are both arranged on the housing bracket, the driving mechanism is in transmission connection with the plurality of universal wheel assemblies, the driving mechanism is used to drive the universal wheel assemblies to rotate and roll; the plurality of universal wheel assemblies cooperate to support profiles; the driving mechanism cooperates with the plurality of universal wheel assemblies to drive a plurality of profiles to enter a cutting device in sequence, and then the plurality of profiles are placed side by side in the cutting device; the cutting device is used to simultaneously cut a plurality of profiles placed side by side; The movable mechanism, the housing support is arranged on the moving end of the movable mechanism, the movable mechanism is used to drive the auxiliary device to approach and move away from the cutting device, and the cutting device, the auxiliary device and the movable mechanism are all installed on the machine platform.

[0006] In the above sawing equipment, after the first profile enters the auxiliary device, the universal wheel assembly drives the profile into the cutting device by rolling. At this time, the first profile is separated from and does not contact the universal wheel assembly. After the second profile enters the auxiliary device, the universal wheel assembly drives the swinging direction and then rolls to drive the second profile to move a certain distance to the left or right relative to the advancing direction. Then the universal wheel assembly returns to the normal position and rolls to drive the second profile into the cutting device. At this time, the second profile is separated from and does not contact the universal wheel assembly. Repeat the above steps to realize the parallel introduction of multiple profiles into the cutting device. After multiple profiles enter the cutting device, the cutting device clamps multiple profiles and cuts multiple profiles simultaneously, solving the problem that traditional equipment can only process single profiles. After cutting is completed, the moving mechanism drives the auxiliary device to move forward. Multiple universal wheel assemblies re-support multiple profiles. The cutting device releases the profiles that have been cut. Then the universal wheel assemblies start to roll. The profiles that have been cut are pushed away from the cutting device by multiple profiles and multiple profiles enter the cutting device, facilitating subsequent cutting. By the number of rolling circles of the universal wheel assemblies, the length of the cut profiles is controlled. This sawing equipment solves the problems of traditional equipment, such as the inability to realize continuous progressive feeding of multiple profiles, only being able to process single profiles, and the need for repeated clamping of multiple profiles, resulting in low production efficiency.

[0027] In one embodiment, as Figures 1 - 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 table 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 table 1. A plurality of air bags 24 are provided on the cross-arm mechanism 23, and the air bags 24 are hinged to the cross-arm mechanism 23. A plurality of clamping spaces for the profiles to pass through are formed between the plurality of air bags 24. The cutting device 2 further includes a plurality of air pumps, and a channel 5 for the output end of the air pump to pass through is provided on the machine table 1. One air pump is correspondingly 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 arranged vertically on the machine table 1, a vertically arranged slide rail is provided on the connecting seat 232, 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 air bag 24 is hinged to the first cross-arm 231. The cross-arm mechanism 23 further includes a first rotation driving block, a first threaded rod and a first moving block. The first rotation driving block is arranged on the connecting seat 232, and the first threaded rod is arranged vertically. One end of the first threaded rod is connected to the output end of the first rotation driving block, 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. Thus, the first cylinder 22 drives the first cross-arm 231 to perform telescopic movement, so as to control the size of the clamping space between the air bags 24, which is convenient for adapting to profiles with more different width dimensions. The design of hinging the air bag 24 to the first cross-arm 231 allows the air bag 24 to dynamically fit the surface of the profile when inflated, avoiding material damage caused by rigid clamping. Through the cooperation of the cross-arm mechanism 23 and the air bag 24, a multi-point flexible clamping space is formed. Compared with the traditional non-side pressure equipment, the elastic contact of the air bag 24 can evenly disperse the clamping force, avoiding local stress concentration of the material caused by rigid clamping, thereby eliminating the risk of material offset during sawing. The flexible characteristics of the air bag 24 can adapt to different profile sections, and the controllable air pressure characteristic further ensures the stability of the clamping force, avoiding profile deformation caused by excessive compression. A plurality of clamping spaces allow multiple profiles to be fixed simultaneously, reducing the downtime for material change. The hinged design of the air bag 24 allows the clamping space to be dynamically adjusted, compatible with profiles of different cross-sectional dimensions (such as special-shaped pipes or variable-section aluminum materials), avoiding frequent fixture replacement.

In this way, the second cylinder 211 drives the lifting platform 212 to achieve rapid lifting in the vertical direction, and cooperate with the second rotation driving block 213 to drive the blade 214 to rotate at high speed, forming a coordinated movement of vertical feeding and rotary cutting.
