Frame (9), first U-shaped piece (10), second U-shaped piece (11), the second positioning pin (12), wherein the first support plate (1) and the second support
Plate (4) is used to support curved sheets, is connected between support plate by two connection frames (9), and the first positioning pin (7) is for fixture
Positioning, first U-shaped piece (10) and second U-shaped piece (11) are respectively welded in the first support plate (1) and the second support plate (4), and two
Baffle (6) is fixed on first U-shaped piece (10) and second U-shaped piece (11), the first steel band (2) and second with straight pin and screw respectively
Steel band (5) rivets link block (3) respectively, tightening structure be with the link block riveted with steel band and with support plate welding it is U-shaped
Block tightens steel band, and link block has screw thread, and nut is used cooperatively with link block, rotating nut, pulls link block, steel band tightening.
Clamp material selects the higher 2Cr25Ni20 of heat resistance.
The tightening structure of this fixture is to be upgraded to U-shaped block of tightening steel with the link block riveted with steel band and with support plate welding
Band, link block have screw thread, and nut is used cooperatively with link block, rotating nut, pull link block, steel band tightening.
Devise baffle arrangement.Tooling has the trend laterally popped up, to avoid side bullet, U-shaped piece of leading portion is slotted, in slot
It is put into block, U-type groove is connected with block with straight pin with screw.
Advantages of the present invention:
1) thin plate quenching fixture compacted position is product surplus, and product is unlikely to deform；
2) quenching precision is high: with positioning finger setting, improving quenching precision, reduces rejection rate.
3) it clamps and facilitates control: fixture steel belt clamping, welded with the link block riveted with steel band and with support plate U-shaped
Block tightens steel band, and nut is used cooperatively with link block, rotating nut, pulls link block, steel band tightening.
4) the higher 2Cr25Ni20 of material selection heat resistance is avoided due to the deformation of products that tooling deforms and generates.
5) Detailed description of the invention
Fig. 1 show a kind of structural schematic diagram of curved sheets quenching fixture of the present invention；
Fig. 2 show the structural schematic diagram that a kind of curved sheets quenching fixture of the present invention clamps；
Fig. 3 show a kind of structural schematic diagram of one side stand component of curved sheets quenching fixture of the present invention；
Wherein, the first support plate 1, the first steel band 2, link block 3, the second support plate 4, the second steel band 5, baffle 6, first is fixed
Position pin 7, connection frame 8, connection frame 9, first U-shaped piece 10, second U-shaped piece 11, the second positioning pin 12.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples:
Referring to Fig. 1, it is a kind of structural schematic diagram of curved sheets quenching fixture of the present invention.The curved surface quenches thin plate
Fixture includes the first support plate 1, the first steel band 2, link block 3, the second support plate 4, the second steel band 5, baffle 6, the first positioning pin
7, connection frame 8, connection frame 9, first U-shaped piece 10, second U-shaped piece 11, fastener is used in connection between the second positioning pin 12 and each part
Deng.Wherein, support plate is to be used to support curved sheets, and two support plates are connected with two connection frames, and positioning pin is fixed for fixture
Position, steel band, link block, U-shaped piece, baffle be for clamping, steel band compress position be curved sheets product residue position.It is fixed
After the completion of position compresses, curved sheets quenching fixture can be put into nitrate groove, be taken out after carrying out quenching treatment a period of time, cooling
It can be taken off product afterwards.
Referring to Fig. 2, the structural schematic diagram that a kind of curved sheets quenching fixture of the present invention clamps.The curved sheets quenching
Fixture steel belt clamping, with the link block riveted with steel band and U-shaped piece of tightening steel band, nut is used cooperatively with link block, rotation
Nut pulls link block, steel band tightening.
Referring to Fig. 3, a kind of structural schematic diagram of one side stand component of curved sheets quenching fixture of the present invention.Support frame as described above
Branch panel products surplus, positioning pin and support plate cooperate, positioning product, and support plate two sides are two clamp systems, and steel band, which compresses, to be produced
Product surplus.Support plate side is equipped with hanging ring, hangs tooling, product immerses nitrate groove by big end together with tooling, reduces product
Quenching distortion.
When curved sheets quenching fixture of the present invention works, specific steps are as follows:
1) whether preoperation inspection lifting bolt is tightened, and whether the screw that connector is connect with support plate is tightened, fixture
Whether baffle lifts.
2) product is placed in tooling support plate, looks for correct installation site using the datum hole of product.
3) 12 positioning product of positioning pin 7 and positioning pin is used, and compresses product, nut rotation tightening with steel band 2 and steel band 5
Steel band.
4) baffle of fixture is put down, judges the size of U-shaped piece with steel band gap, if gap is larger to increase by one piece of gear
Plate, if gap can less immerse fixture and product in nitrate groove.
5) timer is checked, i.e. desirable fixture and product, curved sheets complete quenching treatment when reaching certain time.
Points for attention:
1) tooling when not in use, tooling is placed vertically, tooling is avoided to deform.
2) according to practical curved sheets situation, the cool time is determined.
3) tooling guarantees the safety that tooling uses before use, must be checked.
