Description

Technical Field

[0001] The present invention relates to the technical field of metal processing equipment, and particularly to a double - cutter - head linkage - type light steel keel cutting machine for indoor construction of buildings. Background Art

[0002] In indoor construction of buildings, as the core support structure for decoration projects such as suspended ceilings and partition walls, the processing precision and efficiency of light steel keels directly affect the construction quality and progress. In traditional construction, the cutting of light steel keels mostly relies on handheld electric cutting tools or single - cutter - head cutting equipment.

[0003] The following problems have gradually emerged in the prior art: The single - cutter - head cutting machine needs to perform single - point cutting on the keels one by one. Especially when facing long - sized keels, the operator needs to repeatedly adjust the positioning or perform segmented cutting, resulting in waste of working hours. Although some semi - automatic equipment can fix the keels, the movement trajectory of the cutter head is single, making it difficult to ensure synchronous cutting at both ends, which may cause length errors or uneven cross - sections. Existing equipment relies on manual auxiliary positioning and feeding, and there are safety hazards such as metal chips splashing and the operator's hand accidentally touching the cutter head during high - speed cutting, especially in the complex environment of the construction site, the risk is exacerbated.

[0039] Embodiment 2:

[0040] Please refer to Figures 1 to 7, a double - cutter linkage light steel keel cutting machine for building interior construction according to the present invention. Compared with the first embodiment, this embodiment further includes: The feeding component 4 includes a first lifting cylinder 41 fixedly installed inside the machine tool 1 through bolts; the top plate at the end of the piston rod of the first lifting cylinder 41 is fixedly installed with a second lifting cylinder 42 through bolts; a pushing plate 43 is fixedly installed at the rear end of the piston rod of the second lifting cylinder 42 through bolts; anti - slip protrusions are arranged in a staggered manner on the surface of the pushing plate 43, and a pressure sensor is embedded at the bottom of the pushing plate 43. When it detects that the light steel keel is offset, it triggers the compensatory fine - tuning action of the second lifting cylinder 42.

[0041] Based on the above, the working principle of a double - cutter linkage light steel keel cutting machine for building interior construction is as follows:

[0042] First, when using this equipment, first place this equipment in the working area, and then connect the device to an external power supply to provide the power required for the operation of this equipment, and connect the external control terminal to the electrical components in this equipment through cables;

[0043] Second, during the cutting process, the staff adjusts the horizontal positions of the two cutting components 3 through the control of the first propulsion component 2. Here, the distance between the two cutting components 3 is monitored by the detection component 37. Here, the side plate 372 and the electromagnetic block 373 can quickly fix the stretching shell 371 between the two sliding seats 31 when electrified. At the same time, the grating part 374 performs grating sensing due to the sliding of the sliding seat 31, and the data analysis component 375 processes the data of the grating sensing. And in combination with calculating the width factor of the sliding seat 31, the distance between the sliding seat 31 and the cutting head 34 is detected to ensure the accuracy of the cutting length;

[0044] Third, then the staff places the light steel keel on the top side of the machine tool 1 through an external device, and drives the pushing plate 43 to adjust the position through the first lifting cylinder 41 and the second lifting cylinder 42 to adjust the position of the light steel keel. At this time, the thrust - stop cylinder 35 after adjustment extends synchronously and performs a thrust - stop action on the light steel keel, so that the ends of the piston rods of the pushing plate 43 and the thrust - stop cylinder 35 form a coordinated action on the light steel keel to ensure that the light steel keel is fixed without offset;

[0045] Fourth, after the light steel keel is fixed, the staff controls the pneumatic components inside the sliding seat 31 through an external control terminal to push the two sets of adjusting seats 361 to adjust the spacing, and drives the intermediate section 362 and the side sections 366 on both sides of it to adjust the spatial position through the adjustment actions of the first electromagnetic coil 363 and the permanent magnet rod inside the adjusting seat 361 and the intermediate section 362. Since the intermediate section 362 and the side sections 366 gradually approach the U-shaped groove of the light steel keel, the support top plate 368 and the resilient side plate 369 on the top side of the micro cylinder 367 rotate and fit the inner wall of the light steel keel groove. Here, due to the adjustment actions of the adjusting seat 361, the micro cylinder 367, and the resilient side plate 369, the fitting action on the inner walls of multiple types of light steel keels is improved;

[0046] Fifth, then drive the synchronous motor 32 through the external control terminal to drive the second propulsion assembly 33 and the cutting head 34 to move down gradually. Here, after receiving the electrical signal through the electrical control box 38, the synchronous motor 32 is driven to work synchronously. Here, the wireless module of the signal transmission component 383 receives the electrical signal from the external control terminal, and under the data processing conditions of the data comparison circuit board 384 and the data processor 385, the electrical signal is synchronously output to the synchronous motor 32 through the signal connector of the signal transmission component 383, ensuring the linkage effect of the double cutting heads, and the light steel keel is cut under the rotation action of the cutting head 34. Here, due to the pressure structure of the adjusting seat 361 and the micro cylinder 367, during the cutting and extrusion process of the cutting head 34, the light steel keel will not have a large deformation at the fracture due to the extrusion force; at the same time, the micro cylinder 367 automatically compensates for a buffer stroke of 0.5 - 2 mm, and with the shearing force unloading effect of the rotating cutter head, the flatness error of the fracture plane is controlled within 0.3 mm / m, effectively suppressing the curling deformation problem caused by traditional stamping and cutting.

[0047] The present invention provides a double - cutter head linkage type light steel keel cutting machine for building interior construction through improvement. By setting the cutting assembly 3 and the feeding assembly 4, adopting a closed - loop control mode of grating sensing + data analysis, the displacement of the sliding seat is monitored in real time and the mechanical clearance is compensated. Cooperating with the electromagnetic quick - locking mechanism, the millimeter - level consistency of the cutting length is ensured; through the electromagnetic drive three - section adjustment mechanism and the elastic support structure of the micro cylinder, it can adapt to light steel keels with different cross - section sizes; based on the distributed control system of wireless signal transmission, through the data comparison circuit board, the micro - second - level synchronous response of the double cutting heads is realized, avoiding material off - loading deformation; during the cutting moment, it is monitored in real time through the pressure - sensitive element, and at the same time, with the shearing force unloading effect of the micro cylinder and the rotating cutter head, the curling deformation problem caused by traditional stamping and cutting is effectively suppressed.
