Problems solved by technology

[0003] 1. It needs to be vacuumed, the furnace body is circular, and it is difficult to arrange the parts in the furnace, resulting in a small amount of furnace loading, and the equipment occupies a large area and the manufacturing cost is high.;
[0004] 2. The heating device adopts a muffle tank, and the aging of the muffle tank will lead to a change in the quality of the brake disc after FNC treatment;
[0005] 3. The process of loading and unloading parts is cumbersome. The existing technology uses forklifts or cranes to lift workpieces. The operation requirements are high and the operating environment is complicated, so it is difficult to realize automation;
[0006] 4. The heating furnace adopts a single opening door, which leads to uneven heating of the brake disc during opening the door, resulting in poor surface color consistency;
[0007] 5. The function of the heating furnace is relatively single

Embodiment 1

[0035] Embodiment 1: adopt bell-type furnace of the present invention to carry out FNC treatment (300 brake discs have been loaded onto brake disc support 131 and are divided into 2 groups)

[0036] see Figure 1-7 , the present invention provides a technical solution: a new brake disc FNC automatic muffle-free square bell furnace, including a suspended furnace body 1, furnace bracket 2, rib plate 3, fan 4, heating rod 5, traction rope . There are furnace brackets 2, and the suspended furnace body 1 is a cuboid heating furnace body without a muffle tank. A set of fans 4 and two sets of heating rods 5 are arranged on the top of the suspended furnace body 1, and both sides of the fan 4 are arranged There are heating rods 5, and the suspended furnace body 1 is suspended on the furnace support 2 through a pulley block;

[0037] A furnace bottom 15 is arranged below the suspension furnace body 1, and an H-shaped steel 19 with holes is placed on the furnace bottom 15;

[0038] Th...

Embodiment 2

[0043] Embodiment 2: FNC treatment is carried out by using a traditional muffle furnace (300 brake discs have been mounted on the brake disc bracket 131 and divided into 2 groups)

[0044] The cylindrical furnace body with muffle furnace is lifted, and after the vacuum cover is lifted, a set of brake disc support 131 equipped with brake discs is placed on the base of the vacuum cover, and the vacuum cover is lifted back on the base of the vacuum cover, and finally there will be The furnace body of the muffle furnace is hoisted on the vacuum cover, and the FNC treatment is performed after the vacuum cover is evacuated. After the treatment, the brake disc bracket 131 assembled with the brake disc is taken out, and the above steps are repeated to perform the FNC treatment on another set of brake discs. .

[0045] The following table is the time-consuming comparison table of embodiment 1 and embodiment 2:

[0046] Example Time taken to process 2 sets of brake discs (3...

Abstract

The invention discloses a novel brake disc FNC automatic muffle-tank-free square bell-type furnace, and relates to the technical field of brake disc FNC (ferrite nitrocarburizing, commonly known as tufftriding) treatment equipment. The novel brake disc FNC automatic muffle-tank-free square bell-type furnace comprises a suspension type furnace body, a furnace support, rib plates, a draught fan, a heating rod, a pulley block, a brake disc set, a base, a furnace bottom, a loading and unloading machine and a loading and unloading machine track. The furnace body of the novel brake disc FNC automatic muffle-tank-free square bell-type furnace adopts a cuboid furnace body structure, so that the charging amount is maximized; a traditional muffle tank design is not adopted, vacuumizing is not needed, the production technological process is simplified, and FNC quality changes caused by tank aging are avoided; the loading and unloading machine is additionally arranged for automatic feeding and discharging, and the operation environment is good; the heating furnace body can automatically ascend and descend through the pulley block to replace a furnace door to be opened and closed, and a whole furnace brake disc is uniform in cooling and good in surface color consistency; and non-oxidation stress relief annealing of the brake disc can also be carried out.

Description

technical field [0001] The invention relates to the technical field of soft nitriding treatment equipment for brake discs, in particular to a novel FNC automatic muffle-free square bell furnace for brake discs. Background technique [0002] The following problems exist in the prior art brake disc FNC treatment (soft nitriding) process [0003] 1. It needs to be vacuumed, the furnace body is circular, and it is difficult to arrange the parts in the furnace, resulting in a small amount of furnace loading, and the equipment occupies a large area and the manufacturing cost is high.; [0004] 2. The heating device adopts a muffle tank, and the aging of the muffle tank will lead to a change in the quality of the brake disc after FNC treatment; [0005] 3. The process of loading and unloading parts is cumbersome. The existing technology uses forklifts or cranes to lift workpieces. The operation requirements are high and the operating environment is complicated, so it is difficult ...
