Description

Technical Field

[0001] The invention relates to the technical field of steel plate cutting, in particular to a high-precision steel plate numerical control cutting device. Background Art

[0002] CNC cutting technology is an automated and efficient cutting technology developed on the basis of precise and rapid cutting technology. An important part of CNC cutting technology is the CNC cutting machine, which is composed of CNC system, programming system, gas system and mechanical operation system. At present, enterprises often use CNC cutting machines to cut steel plates when producing and processing steel plates.

[0003] For example, the invention with application number CN202121938509.2 belongs to the technical field of CNC cutting equipment, and discloses a high-precision CNC cutting machine for steel plate processing. The invention arranges a horizontal plate, teeth, a driving motor and gears. Due to the operation of the driving motor, the horizontal shaft and the gears will rotate. Since the teeth and the outer surface of the gears are in a state of mutual meshing, the horizontal plate and the vertical plate will move downward through the teeth. At this time, the vertical block and the horizontal block will contact the surface of the steel plate and fix the steel plate, thereby avoiding accidental shaking when cutting the steel plate and improving the work efficiency of the staff; however, the existing steel cutting machine is not convenient to express the cutting range intuitively when cutting steel, which makes it easy for the processing personnel to have deviations in the cutting size and leads to low cutting accuracy.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a high-precision steel plate CNC cutting equipment is provided. Summary of the invention

[0005] The object of the present invention is to provide a high-precision steel plate CNC cutting equipment to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a high-precision CNC cutting equipment for steel plates, comprising a cutting frame and a limit assembly, wherein a guide rail is arranged on the front side of the cutting frame, and the limit assembly for increasing the steel plate cutting accuracy is arranged at the lower end of the cutting frame, and the limit assembly comprises a hydraulic rod, a force equalizing frame, a connecting plate, a limit frame and an anti-slip gasket, the output end of the hydraulic rod is connected to the force equalizing frame, and a connecting plate is installed at the lower end of the force equalizing frame, a connecting limit frame is installed on the side of the connecting plate, and an anti-slip gasket is arranged at the lower end of the limit frame, and a laser cutting head is arranged above the inside of the limit frame.

[0007] Furthermore, the shape of the limiting frame is a long square shape, and the limiting frame and the connecting plate are vertically distributed.

[0008] Furthermore, a mounting plate is provided on the outside of the laser cutting head, and a hydraulic rod 2 is installed on the upper end of the surface of the mounting plate. The fixed end of the hydraulic rod 2 is connected to a fixing frame, and the upper end of the fixing frame is connected to a control machine through a line. A display screen is provided on the front side of the control machine.

[0009] Furthermore, columns are provided at both ends of the cutting machine frame, and a second guide rail is provided inside the lower end of the column through a roller, the lower end of the second guide rail is connected to a cutting processing table, and a storage table is provided in the middle of the cutting processing table.

[0010] Furthermore, a protective component for cutting protection is provided on the outer side of the upper end of the limit frame, and the protective component includes a protective cover, a hard frame, a side plate and a hydraulic rod three. The top of the protective cover is connected to the hard frame, and the outer side of the hard frame is connected to the side plate, and the inner side of the side plate is provided with a hydraulic rod three.

[0011] Furthermore, the protective cover and the hard frame are an integrated structure, and the shape of the hard frame is consistent with the shape of the limit frame. The side panels and the hydraulic rods are symmetrically arranged in four groups about the central axis of the hard frame.

[0012] Furthermore, an auxiliary component for assisting the steel plate limiting is provided on the inner side of the guide rail 2, and two groups of auxiliary components are symmetrically arranged about the central axis of the cutting processing table, and the auxiliary component includes positive and negative threaded screws, a slider, a hydraulic rod four and an auxiliary positioning rod, a slider is provided on the outside of the positive and negative threaded screws, and a hydraulic rod four is installed on the side surface of the slider, and an auxiliary positioning rod is installed on the output end of the hydraulic rod four.

[0013] Furthermore, the hydraulic rod four and the auxiliary positioning rod are arranged in four groups, and the auxiliary positioning rod is in an L-shape.

[0014] Furthermore, the operation method is as follows: place the steel to be processed on the storage table, put it upright, turn on the motor at the end of the positive and negative screw rods to make it rotate, thereby controlling the slider to move along the positive and negative screw rods. At this time, the slider is driven to drive the hydraulic rod four and the auxiliary positioning rod to make corresponding position adjustments. The auxiliary positioning rod clamps and limits the four corners of the steel as the slider moves to prevent the steel from moving. While clamping and limiting, control the hydraulic rod four to drive the auxiliary positioning rod to make corresponding left and right adjustments, so that the auxiliary positioning rod limits the steel in place, and then adjust the position of the column on the guide rail two to determine the laser The cutting position of the cutting head allows the laser cutting head to subsequently cut the steel along a pair of guide rails. At the same time, when the hydraulic rod 1 is extended, the limit frame moves down to the surface of the steel. The limit frame is driven by the hydraulic rod 1 to divide the area on the surface of the steel. At the same time, the limit frame exerts a downward limit force on the steel under the drive of the hydraulic rod 1, thereby increasing the stability of the steel during cutting.

[0016] 1. The present invention uses a limit frame to divide the steel surface into areas under the drive of hydraulic rod 1, so that processing personnel can intuitively understand the cutting position of the laser cutting head on the steel, and the steel is cut with high precision. At the same time, the limit frame exerts a downward pressure on the steel under the drive of hydraulic rod 1, thereby increasing the stability of the steel during cutting and avoiding the deviation of the steel. The anti-slip gasket increases the anti-slip degree of the contact between the limit frame and the steel surface, thereby increasing the stability of the contact. The connecting plate is used for the connection of the limit frame and increases the area of ​​the limit frame pressing down on the steel.

[0017] 2. The present invention uses the protective cover to act as an external shield when the laser cutting head is cutting, thereby avoiding the splashing of sparks during cutting and increasing the safety factor. The protective cover can be folded and contracted accordingly with the extension and retraction of the hydraulic rod three, which is convenient for processing personnel to check the cutting position. The hard frame makes the protective cover smoother when contracted and unfolded, avoiding the deformation of the protective cover during expansion and causing incomplete protection.

[0018] 3. The present invention controls the movement of the slider by means of positive and negative screw rods driven by a motor. After the slider is driven, it drives the hydraulic rod four and the auxiliary positioning rod to make corresponding position adjustments. The auxiliary positioning rod clamps and limits the four corners of the steel as the slider moves to prevent the movement of the steel. At the same time, the hydraulic rod four drives the auxiliary positioning rod to make corresponding left and right adjustments, so that the auxiliary positioning rod can limit the steel more effectively to prevent the movement of the steel from affecting the processing accuracy.
