Problems solved by technology

In actual production, such parts are processed on the plane by ordinary CNC gantry boring and milling machine according to the conventional process, and neither the surface roughness nor the flatness can meet the requirements.
The earlier lamination-type hot-press machines used the planing and grinding process for the large-size plane processing of the hot-pressed plate. The advantage of this process is that the large-scale planer is used to modify the grinding head equipment. The equipment is simple and the cost is low. The disadvantage is that the surface roughness, especially the plane degree cannot be guaranteed

Embodiment 1

[0018] attached figure 1 , 2 And 3 is an embodiment of the present invention, is that the production width is 1380mm wood-based panel flat pressing type novel hot press machine hot press plate plane processing. The size of the workpiece hot-pressing plate 4 is 100*1380*6850mm, and the material is a special custom-made pretreatment die steel (close to NAK80), with a hardness of about HRC40. 1. The CNC gantry boring and milling machine is imported from Jinan No. 2 Machine Tool Factory (model XMK2136*12). The accuracy indicators of the machine tool must meet the acceptance standards of JB6086-92. Adjust the spindle of the main milling head 1 of the boring and milling machine so that the spindle taper hole axis is Vertical state, fine-tuning key items such as spindle end jump to improve the measurement accuracy, and the runout detected by the rotary angle measuring stick at the extension of 300mm is less than 0.008mm. 2. Face milling cutter head 3 adopts SECO eight-sided adjusta...

Abstract

The invention relates to a method for processing the plane of artificial sheet thermal compressor, which uses national general digit-control crane boring-mill machine to bore and mill the plane to realize the high roughness and flatness, wherein said thermal compressed sheet is the pretreated mould steel, whose rigidity is HRC40, and the plane size of work-piece is large. The invention adjusts the accuracy of machine, adjusts the plane milling blade, and the work-piece is clamped via the electromagnetic absorb disc, via special parameters and digit-control program, using high-pressure air to cool it, to realize the high accuracy demand. The smoothness of inventive product can reach Ra0.4-Ra0.2, and flatness can reach 0.10.

Description

technical field [0001] The invention relates to a process method for processing a hot-pressed plate of a wood-based panel hot press, in particular to plane milling of a hot-pressed plate of a wood-based panel hot press to achieve higher surface roughness and flatness and improve the milling quality of a large plane processing method. technical background [0002] Design and develop a new type of wood-based panel flat-pressing hot press, and the hot pressing plate is the key to the new hot pressing machine. The workpiece of the hot-pressed plate is made of specially customized pre-treated mold steel with a hardness of about HRC40. The plane size of the workpiece is relatively large, and the two planes require extremely high surface roughness, flatness and parallelism. It is very important to master the plane processing method of. In actual production, such parts are processed on the plane by ordinary CNC gantry boring and milling machine according to the conventional proces...
