Embodiment 1

[0036] Such as Figure 3-5 As shown, the present invention is an adjustable double-cutter head cutter device for making phenolic air ducts, including a cutter installation block 1, a cutter adjustment block 2, a cutter adjustment frame 3 and a cutter head 4, a cutter installation block 1, and a cutter adjustment block 2 and tool adjustment frame 3 are made of light aluminum alloy to reduce the type of tool device, easy to use, and easy to process. The tool mounting block 1 is provided with a tool rest mounting groove 5, and the knife rest mounting groove 5 is a concave structure. The cutter adjusting block 2 can be moved in the knife rest mounting groove 5 by adjusting the adjusting block 9 to adjust the cutting distance between the two blades. The bottom of the knife rest mounting groove 5 is provided with a cutter adjusting groove 6; Adjusting frame mounting groove 7, adjusting frame mounting groove 7 two ends are provided with adjusting hole 8, cutter adjusting block 2 bott...

Embodiment 2

[0042] Such as Figure 3-5 As shown, a kind of adjustable double cutter head cutter adjustment method for making phenolic air duct of the present invention, on the basis of embodiment 1, comprises steps:

[0043] Step 1) Calculate the protruding length of the cutter head according to the cut angle α of the phenolic air duct made and the thickness d of the cut phenolic formaldehyde;

[0044] Cot1 / 2α=d / S (1)

[0045] S is the length of the tool head protruding from the tool mounting block

[0046] Deduced by formula (1), S=d / (Cot1 / 2α) (2);

[0047] Step 2) adjust the cutter head extension length S according to the cutter head extension length S obtained from the formula (2);

[0048] Step 3) Calculate the distance between the roots of the two cutter heads according to the cut angle α of the phenolic air duct made and the thickness d of the cut phenolic formaldehyde;

[0049] tan1 / 2α=K / 2S (3)

[0050] K is the distance between the roots of the two cutter heads

[0051] Dedu...

Abstract

The invention discloses an adjustable double cutting head cutter device used for manufacturing a phenolic aldehyde air duct and an adjusting method. The adjustable double cutting head cutter device comprises a cutter mounting block, cutter adjusting blocks, cutter adjusting frames and cutting heads. Cutter adjusting block mounting grooves are formed in the cutter mounting block, and cutter adjusting grooves are formed in the bottom of a cutter frame mounting groove. Adjusting frame mounting grooves are formed in the cutter adjusting blocks. Adjusting holes are formed at the two ends of each adjusting frame mounting groove, and adjusting blocks mounted in the cutter adjusting grooves are arranged at the bottoms of the cutter adjusting blocks. The cutter adjusting blocks are used for, on one hand, adjusting the cutting distance between two blades on one hand, and on the other hand, mounting the cutter adjusting frames. Each cutter adjusting frame is of a shaft structure convenient to rotate and adjust. Fastening threaded end heads are arranged at the two ends of each cutter adjusting frame, and a cutting head mounting groove is arranged in the middle of each cutter adjusting frame. The two cutter adjusting blocks are mounted in the cutter adjusting block mounting grooves, and adjusting blocks of the two cutter adjusting blocks are connected through an adjusting screw rod. The cutter adjusting frames are mounted in the adjusting frame mounting grooves. The two ends of each cutter adjusting frame are adjusted and fixed by locking nuts. The cutting heads are mounted in the cutting head mounting grooves.

Description

technical field [0001] The invention relates to the field of tools for making phenolic air ducts, in particular to an adjustable double-blade cutter device and an adjustment method for making phenolic air ducts. Background technique [0002] At present, the special knives for phenolic air ducts on the market have two structures, single-knife head and double-knife head (such as figure 1 and 2 shown), and the cutter heads of these two structural cutters are fixed, generally 45-degree cutters, these two cutters are suitable for the production of most types of phenolic air ducts, such as square structures and cross-sections The same phenolic air duct is manufactured, but the phenolic air duct produced is not square, or the cross-section is changed, and the phenolic air duct is not cut at a 45-degree angle. The existing two tools cannot meet the production requirements and require workers. According to the experience to cut the phenolic board, the production quality of the phen...
