(1) Receiving order:

(1) After receiving the processing order, the operator must understand its meaning and check whether the data indicated in the drawing are consistent with the relevant data of the order.

(2) In the case of overlap, then the material planning and procurement procedures.

(2) Acquisition:

(1) After the model, specification and color of the materials to be collected are signed by the warehouse keeper, the materials shall be collected after verification according to the single quantity.

(2) outward transportation with multiple cranes; Less is manual, transported to the cutting machine for cutting.

(3) cutting:

(1) When cutting composite board with imported cutting machine, first adjust the locator to the required size, then cut a little bit first, and then check whether the size is consistent with the required size. If they are consistent, start cutting; otherwise, adjust them to be consistent.

(2) When cutting composite board, the cutting direction must be from left to right and from top to bottom, and reverse cutting is not allowed. The board must face up. When two people cut together, they must use simple gestures or passwords to indicate that they can cut, and only one operator can step on the clutch.

(3) After cutting, check whether the data of the cutting plate is consistent with the processing sheet, and the allowable error is1.0mm..

④ Place the printing plate gently on the cleaning platform to avoid damaging the printing plate surface.

(4) Slotting:

(1) First, check whether the material data used to cut the plate meets the requirements of the processing order.

(2) When planning, the processing order must be analyzed, confirmed and finalized again.

(3) The operation must require one person to be in charge of control, and the planing direction should be from left to right and from top to bottom. It is not allowed to backcut | source | test | big |, and the strength should be sufficient and stable, so that the positioning wheel and the composite plate can be attached tightly, otherwise the groove depth will be inconsistent.

(4) When planing, adjust the monitor to the required size. When debugging, use a small piece of composite board to debug and plane. The debugging effect must meet the requirements of composite plate planing. The depth of planing must ensure that the thickness of polyethylene on the decorative back is between 0.3 mm and 0.5 mm, and the width of the planing notch is between 3 mm and 4 mm, which will not affect the appearance of the decorative back. The position and size error of the groove is allowed to be 0.5 mm.

(5) after planing, gently put down, so as not to damage the veneer.

(5) Angle cutting:

Punching must be carried out on the punch press according to the drawing position, and the cutting angle is not allowed to exceed the center line of the planing groove.

(6) Bending:

① Be careful not to bend repeatedly to avoid fatigue damage. Bend twice at most, and the allowable dimensional error is1.0mm..

(2) After bending, lightly stroke the protective film at the bending place of the composite board with the back of wallpaper knife, being careful not to scratch the board surface, about 4 mm away from the bending place, and then tear off the protective film.

(7) Plate assembly and reinforcement:

① Use isopropanol/water mixture (1: 1) or xylene to clean the joints between the composite board, the attached frame, the reinforcing ribs and the 3M adhesive tape.

(2) The 2)3M adhesive tape shall be bonded with the attached frame and reinforcing ribs first. During operation, do not touch the 3m adhesive tape and the cleaned surface with your hands or other objects.

(3) Sit the attached frame with 3M adhesive tape in the composite plate box, and tap the attached frame with your hand or rubber hammer to make the edge of the composite plate enter the hook groove of the attached frame. The 3M adhesive tape is firmly bonded to the composite plate, and the seam gap of the folded edge of the composite plate is less than 0.4 mm 。

(4) According to the design requirements, drill holes with a drilling template, with the spacing of core-pulling rivets of 350mm, and arrange holes from both ends to the middle, and then install self-tapping nails or core-pulling rivets.

⑤ The reinforcing ribs are closely attached to the composite plate. Self-tapping nails or core-pulling rivets are used at the joints between both ends of the reinforcing ribs and the folded edges of the composite plate, and care shall be taken not to damage the veneer of the plate.

(8) Re-inspection:

(1) The allowable deviation of the length and width of the assembly plate is 65438 0.5mm; ; The allowable deviation of diagonal dimension is ≤ 2.5mm; Plate thickness of 0.5mm；; The allowable deviation of the angle of the corner plate is 0.5, and if it exceeds this data, it is a nonconforming product.

(2) Check whether each processing procedure is carried out as required and whether the processing effect is qualified.

(9) Storage:

After passing the inspection, put the decorative surface and decorative surface on the designated finished product rack, making an angle of 80 with the horizontal plane. Be careful not to lift the plate horizontally during handling, but to lift it sideways to avoid deformation of the plate.

◆ Description:

A, using 3M tape for temperature requirements:

(1) t > 10 c with 4950 adhesive tape;

② 0 c ≤ t ≤10 c with 495 1 adhesive tape;

(3) When the ambient temperature is lower than 0 C, 3M adhesive tape is not allowed.

B, when using aluminum veneer, ensure that the thickness of the aluminum plate at the bend is not less than 2mm.

C, processing metal paint decorative plate, should pay attention to the direction, according to the direction indicated in the design drawings.
