Technical Field

The utility model belongs to the technical field of section bar cutting, and particularly relates to a full-automatic four-axis numerical control cutting device for cutting a section bar by laser.

Background

The section bar is cut by applying laser in the prior art, and the specific work is as follows: the section bar sets up on rotatory fixture, drive the section bar that sets up on rotatory fixture through the motor and rotate and slide to the cutting head direction and carry out the pay-off (the cutting head is fixed motionless), realize the intercepting to the section bar, operation such as punch, but this technique is that the laser cutting head irrotational but the section bar is rotatory, to the intercepting of section bar, operation such as punch, all rely on material feeding unit to work, because the section bar quality is big, the length is inequality the reason, the section bar is removing or is rotating the in-process because the inertia is great, it is difficult to carry out accurate control to the section bar, the section bar intercepting appears easily, the failure of punching.

For example, the utility model patent application with the name of 'numerical control cutting equipment' and the application number of 201710754018.4 of the Chinese patent application discloses a numerical control cutting equipment, which comprises a table body, a feeding seat and a rotary cutting machine head, wherein the feeding seat provided with a section bar holding and positioning mechanism and a feeding driving gear slides along the X-axis direction on two linear guide rails arranged on the table body, the feeding rack arranged on the platform body on the inner side of the linear guide rail is meshed with a feeding driving gear which provides power for the sliding of the feeding base on the linear guide rail, the profile slides to a rotary cutting machine head on the linear guide rail along with the profile clamping and positioning mechanism to operate through the rotation of a feeding servo motor which is arranged on the feeding base and connected with the feeding driving gear, and a V-shaped material support frame arranged on the platform body automatically adjusts the height to support the profile according to the sliding state of the profile clamping and positioning mechanism; the cutting head moves in the X-axis direction and the Y-axis direction relative to the section bar and rotates around the Z-axis direction, and the cutting head is matched with the movement of the section bar in the Z-axis direction to realize the operations of cutting, punching and the like on the section bar. The problem of single function in the existing laser cutting is solved through the movement of the cutting head with three degrees of freedom, the blank of the movement of the cutting head with multiple degrees of freedom in the existing pipe cutting field is filled, a pipe cutting mode that the cutting head with three degrees of freedom movement and the one-degree of freedom movement feeding device are combined is created, and the problems that the precision is low and waste materials are easy to generate when the sectional material is cut in the rotating process due to the fact that the length of the sectional material is too long and the gravity center is lowered are solved. In order to match the rotatory technical scheme of cutting head, need design the cable length adjusting device who matches with it, the cutting head will rotate, just need to satisfy the cable on the cutting head and follow the removal, nimble realization is receive and release, otherwise piled up problem just appears easily, so present cutting head is fixed mounting, and let the cutting pipe fitting rotate, in order to realize the cutting to the pipe fitting, but in order to match with cutting head pivoted cutting equipment, need design one kind can be along with the cutting head rotates and nimble device of adjusting cable length, in order to satisfy the cutting head and rotate the demand of receiving and releasing to the cable in the cutting process. For example, chinese patent No. 201820047678.9 discloses a 720-degree cable take-up and pay-off adjusting device for a laser pipe cutting machine, but the adjusting device in this patent document utilizes the dead weight of the cable, and the cable is led to generate appropriate displacement according to the movement change of the cutting head by the guiding action of a slide block on a slide way. The problem that this kind of structure exists is exactly because the dead weight of cable, can make the cable be in the state of tensioning all the time, and the cutting head is when forward rotation needs the cable extension, can be more difficult, has great pulling force to the cable, has the hidden danger to the safety of cable.

According to the technical scheme, the automatic operation of the section bar in the X-axis feeding process and the cutting process of the rotary cutting head is realized, the section bar is generally hoisted to the section bar supporting frame manually in the existing feeding process, and then the section bar is clamped by the section bar clamping and positioning mechanism and then is fed along the X axis for cutting. The existing material supporting frame only has a supporting function, cannot automatically receive materials and cannot adjust the supporting height according to the shape and the size of a section, so that the existing cutting equipment cannot automate the whole processing flows of feeding, supporting height adjustment, section supporting, feeding, rotary cutting and the like.

Under the drive of a feeding servo motor 8, a feeding driving gear moves on a feeding rack 7 along an X axis so as to drive the section clamping mechanism 3 to move along the X axis direction, and a section clamped on the section clamping mechanism 3 moves to the rotary cutting machine head 5 along with the section clamping mechanism 3.

As shown in fig. 1 and 2, the material supporting mechanism 4 and the feeding seat 2 are arranged at the same side of the platform body 1, and the material supporting mechanism 4 and the platform body 1 can be separately and independently arranged to improve the flexibility of the material supporting mechanism 4, and can also be fixed at the bottom of the platform body 1 to strengthen the supporting effect on the platform body 1. The material supporting mechanism 4 can be provided with a plurality of groups in parallel according to the length of the section bar so as to realize the balanced support of the section bar.
