Description

Technical Field

[0001] The invention relates to the technical field of cutting machines, and in particular to a steel plate cutting machine with an adjustment function. Background Art

[0002] With the development of science and technology and society, people's demand for steel is gradually increasing. Steel plates, as a kind of steel, need to be cut before use. Existing cutting devices can generally only cut in the vertical direction, and thus can only cut vertical sections. However, in actual use, beveled sections are often required. Therefore, a steel plate cutting machine with adjustable cutting angle is needed to solve the above problem.

[0003] The Chinese invention patent document (Announcement No.: CN110773785A) discloses a steel plate cutting machine with adjustable cutting angle, which belongs to the field of cutting machines and includes a base, a mounting frame, a working platform, a guide rail, a slider, an adjustment turbine, a first mounting rod, a second mounting rod, an adjustment worm, a cutting motor, a cutting blade, and a cutting seam. The steel plate can be placed on the working platform to facilitate cutting, and the slider connected to the guide rail is used to drive the adjustment turbine and the cutting blade of the cutting motor on the slider to move, and the cutting motor is used to drive the cutting blade to rotate, thereby realizing the cutting of the steel plate, and the adjustment worm is rotated to drive the adjustment turbine to rotate, and then the cutting blade of the cutting motor on it is driven to rotate, thereby realizing the angle adjustment of the cutting blade, realizing the change of the cutting angle, and because the worm is used for transmission, the angle change is more accurate.

[0004] However, in the above patent, after adjusting the cutting angle, the cutting mechanism is supported only by the self-locking between the worms, without a separate supporting and stabilizing mechanism. Since the cutting mechanism has a certain gravity, the life of the worm gear will be reduced after long-term use, and the teeth between the worm gear will be damaged, affecting the normal cutting work. When the protective shell on the cutting disc is damaged, the cutting disc needs to be removed together, which is time-consuming and laborious. Therefore, we propose a steel plate cutting machine with an adjustment function to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to overcome the defects of the prior art and provide a steel plate cutting machine with an adjustment function.

[0024] The implementation principle of the steel plate cutting machine with adjustment function in the embodiment of the present application is as follows: first, the staff puts the steel plate to be cut on the fixed seat 23, and then uses multiple manual cranks 27 to drive multiple fixed screws 25 to rotate, and then multiple fixed screws 25 drive multiple fixed disks 26 to move downward to fix the steel plate. After the fixation is completed, the control console 20 is used to start the moving motor 32, so that the output shaft of the moving motor 32 drives the moving screw 28 to rotate, and the moving screw 28 drives the screw barrel 29 to move by the sliding limit between the two T-plates 31 and the two limit grooves 30, and then the two T-plates 31 drive the moving bottom plate 2 to move, and then multiple lifting push rods 3, the adjustment seat 4, the adjustment plate 8 and the cutting disk 35 are moved in position, which can be adjusted according to the actual situation. The cutting disc 35 can be adjusted to a suitable position as required, and the multiple lifting push rods 3 can drive the adjustment seat 4 to move upward or downward, so as to adjust the height of the cutting disc 35 to contact the steel plate. The control console 20 drives the No. 1 electric push rod 19 to drive the self-locking plate 16 to rotate upward with the side seat 15 as the fulcrum to disengage from the teeth of the ratchet 14, and at the same time start the cutting motor 33. The output shaft of the cutting motor 33 drives the cutting rotating rod 34 to rotate, and drives the cutting disc 35 to rotate through the cutting rotating rod 34 to cut the steel plate. At the same time, the two No. 2 electric push rods 22 can drive the fixed seat 23 to move to adjust the position of the steel plate, and cooperate with the cutting disc 35 to complete the cutting of the steel plate. When it is necessary to bevel the steel plate, the control console 20 is used to start the adjusting motor 6 so that the output of the adjusting motor 6 The shaft drives the adjusting shaft 7 to rotate, and the adjusting shaft 7 drives the adjusting plate 8 to rotate, and then drives the cutting disk 35 to adjust the angle. At the same time, the adjusting shaft 7 drives the indicator needle 13 to rotate and cooperate with the dial 12, which can clearly display the degree value of the adjusted angle. At the same time, when the adjusting shaft 7 rotates, it drives the ratchet 14 to rotate. When the angle adjustment of the cutting disk 35 is completed, the control console 20 can be used to drive the No. 1 electric push rod 19 to drive the self-locking plate 16 with the side seat 15 as the fulcrum, so that one end of the self-locking plate 16 moves downward in an arc and is stuck in the tooth gap of the ratchet 14, thereby achieving support and braking of the ratchet 14.

Since the protective shell 11 on the cutting disk 35 may be damaged after a long time of use, when the protective shell 11 needs to be replaced, the two toggle plates 38 can be toggled to drive the two L-shaped fixing plates 37 to move and compress the two fixing springs 36. At the same time, the two L-shaped fixing plates 37 are separated from the two mounting plates 39, and the two mounting plates 39 and the protective shell 11 can be taken out from the slot upwards, and a new protective shell 11 and mounting plate 39 can be replaced. Repeat the above steps, put the two mounting plates 39 in the two slots, and release the two toggle plates 38.Then, the two fixing springs 36 release their elastic force to drive the two L-shaped fixing plates 37 to move and insert into the two corresponding clamping grooves to fix and limit the two mounting plates 39, thereby completing the installation of the protective shell 11. Compared with the prior art, which requires the removal and replacement of the cutting disc 35, etc., this device is more convenient and quick.
