Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cutting equipment, and mainly relates to a bimetal plate production process and a processing device. BACKGROUND

[0002] A bimetal plate is a layered composite material formed by two or more heterogeneous metals through metallurgical bonding, which has the mechanical properties and functional characteristics of the interface metal. Its core advantage lies in performance complementation through material combination, such as high manganese steel and bearing steel composite to improve wear resistance, and stainless steel and carbon steel composite to balance corrosion resistance and cost efficiency. Current mainstream production processes include hot rolling, explosion welding and diffusion bonding, among which hot rolling is the preferred choice for industry due to its high efficiency and good bonding strength.

[0003] However, there are significant technical bottlenecks in the subsequent plate cutting link: during subsequent production of the plate, a laser cutting head is generally used for slitting, and the plate is roughly cut into plates of different widths according to requirements. The traditional cutting equipment generally adopts a fixed knife distance design, which is inconvenient to cut and cannot quickly adjust the distance between the cutting heads to cut metal plates of different widths. Therefore, it is necessary to propose an improvement measure to solve the above technical problems. SUMMARY

[0009] Preferably, the telescopic plate frame comprises a first plate member and a second plate member, the first plate member is vertically slidably inserted into the second plate member, the second plate member is fixedly installed at the top of the frame on both sides of the through slot, the threaded screw rod and the slide rod are both installed on the upper part of the first plate member, and the driving motor is also installed at a corresponding position outside the upper part of the first plate member; a pneumatic cylinder is further installed in the second plate member, the telescopic end of the pneumatic cylinder is connected with the bottom of the first plate member, and the first plate member is driven to move up and down by the pneumatic cylinder.

[0010] Preferably, strip-shaped sliding grooves are formed in the frame on both sides of the upper part of the frame, a plurality of sliding seats are slidably clamped in the strip-shaped sliding grooves, and the U-shaped mounting frame is vertically slidably inserted into the sliding seats on both sides of the frame.

[0013] The present invention discloses a bimetallic sheet production process using the aforementioned processing equipment, which specifically includes the following steps: Before cutting, the positions of each laser cutting component are pre-adjusted according to the set cutting width of the sheet, so that the laser cutting head of the laser cutting component is located above each cutting point of the sheet. Then, the bimetallic sheet is fed in from one side of the frame, so that the sheet passes through the upper and lower rows of pressure rollers while being rolled and flattened. When the sheet passes through the through groove, the laser cutting component is controlled to descend, and the laser cutting head to be cut is turned on to perform laser cutting on the sheet being transported.

[0014] Compared with the prior art, the beneficial effects of the present invention are: This invention utilizes multiple longitudinally spaced laser cutting components arranged on a frame, with optimized structural design. During operation, bimetallic sheets are conveyed by two rows of pressure rollers, which simultaneously roll and flatten them to improve their levelness. The laser cutting heads of the laser cutting components synchronously cut different positions of the bimetallic sheets, producing multiple sheets of varying or identical widths. The invention is highly convenient to use. To adjust the width of the bimetallic sheets being cut, the wing-shaped locking screws on the U-shaped mounting brackets that need to be moved are tightened, while those on the U-shaped mounting brackets that do not need to be moved are loosened. Rotating the threaded screw allows the corresponding U-shaped mounting brackets to move synchronously, thereby adjusting the distance between the laser cutting heads to cut bimetallic sheets of different widths. The overall design is ingenious, allowing for adaptive and rapid adjustment of the distance between the laser cutting components. Adjustment can be made by moving a single laser cutting component longitudinally, or by selectively moving two or more laser cutting components longitudinally. Its use is highly flexible, convenient, and practical. Attached Figure Description
