Abstract

The utility model discloses a universal low-cost combined boat which comprises a main plate, two supporting bars and two protecting bars, wherein a straight groove is arranged at two side edges of a square plate, and two first short grooves vertical to the straight groove are arranged at the two side edges of the square plate; a raised line matched with the straight groove is arranged at the lower part of the supporting bars, and two second short grooves with two ends vertical to the raised line are arranged at the lower part of the supporting bars; the position of the first short grooves corresponds to that of the second short grooves, and the groove width is the same as the thickness of the protecting bars; and the protecting bars are inserted into the second short grooves at the same end of the two supporting bars and extend into the first short grooves of supporting edges of the square plate, the upper edges of the supporting bars are lower than the upper surfaces of the supporting bars, and the lower edges of the supporting bars are higher than the product laying surface of the main plate. The combined boat can not only increase the product loading amount in the boat, but also be convenient to clean and unload, have small storage space, improve the gas flow direction in the boat and improve the product quality.

Description

The combination graphite boat

Technical field

The design relates to a kind of CEMENTED CARBIDE PRODUCTION graphite boat.

Background technology

CEMENTED CARBIDE PRODUCTION adopts cost higher graphite circle boat dress boat, sintering at present mostly, and cost price is between 300-650 unit.Because of being subjected to the influence of boat level altitude, when producing the differing heights product, then must be equipped with the graphite boat of corresponding height, after the production of certain model is intact, this batch boat might have been caused the not only raising of production cost like this by idle, and boat is deposited and also needed very big space.Simultaneously, repeatedly graphite boat has distortion behind the sintering, and its making, material are had relatively high expectations.

The utility model content

The utility model is at the problems referred to above, and a kind of have versatility, combination boat that cost of manufacture is low are provided, and can improve the boat charge of product, also is convenient to cleaning, unloads boat, and the boat parking space is little, improved simultaneously that atmosphere flows in the boat, improved product quality.

Combination graphite boat of the present utility model comprises mainboard, also comprises 2 support bars, 2 ceilings; Side's plate dual-side is designed to parallel support edge upwards, the band straight trough, and is positioned at inboard, two ends, support edge, vertical and terminate in two first parallel short grooves of straight trough; The raised line that the design of the bottom of support bar has and straight trough coincide, and be positioned at the support bar two ends and from it the surface extend downwards, perpendicular to two of the raised line second parallel short grooves; The described first short groove, the second short groove position correspondence and groove width are identical with the thickness of ceiling; In the second short groove of 2 same ends of support bar of ceiling insertion and in the first short groove of plate support edge, the side of stretching into, its top is lower than the support bar upper surface, bottom is higher than product placed side on the mainboard.

Because mainboard is on the basis of square plate, dual-side is designed to parallel support edge upwards, the band straight trough to make: when the dress thin product, support bar can be installed, ceiling can directly be piled up neatly dress, and is promptly firm, can save the shove charge space again, improves one time batch; At dress height during, can on the mainboard dual-side, insert and support bar that product adapts is adorned boat, gone into stove greater than the product of mainboard dual-side height.Support bar can be propped up last layer side's plate again, makes product and top boat bottom maintenance certain distance in the boat; In the second short groove of 2 same ends of support bar of ceiling insertion and in the first short groove of plate support edge, the side of stretching into, not only strengthened boat intensity, but also make product dress boat after form the protection that four limits are surrounded, guarantee that boat can not toppled over or drop out to the product in the boat in transfer process; The ceiling top is lower than the support bar lower surface, bottom is higher than the mainboard upper surface; promptly keep certain space with boat bottom and upper strata boat bottom; both protected the not large-area hydrogen that directly is subjected to of product to wash away; make not only atmosphere in boat but also can form upper and lower convection current; make forming agent can be smooth and easy, taken away by hydrogen completely and get rid of; can not cause the generation of phenomenons such as product carburizing and peeling, improve product quality.

Use combination boat of the present utility model, round boat list boat boat charge improves about 25%, and the cleaning of unloading boat and boat of product and the also round boat convenience of spary.The support bar cost of manufacture is low, and the support bar that is equipped with multiple height can adapt to the product of different model specification, substitutes former all graphite circle boat, and parking space is little, is fit to very much the production and the use of special-shaped product, non-tender.

The specific embodiment

Shown in Fig. 1～9, combination graphite boat of the present utility model comprises 2,2 ceilings 3 of 1,2 support bar of mainboard; Side's plate 1 dual-side is designed to parallel support edge 11 upwards, band straight trough 12, and is positioned at inboard, 11 two ends, support edge, vertical and terminate in two first parallel short grooves 13 of straight trough 12; The design of the bottom of support bar 2 has the raised line 21 that coincide with straight trough 12, and be positioned at support bar 2 two ends and from it surface 23 extend downwards, perpendicular to two of the raised line 21 second parallel short grooves 22; First short groove 13, the second short groove 22 position correspondences and groove width are identical with the thickness c of ceiling 3, and 12 distances of straight trough are suitable with the length b of ceiling 3; In second short groove 22 of 2 support bar 2 same ends of ceiling 3 insertions and the first short groove 13 of plate support edge, the side of stretching into 11, its top is lower than support bar 2 lower surfaces 23, bottom is higher than product placed side 14 on the mainboard 1.

Because mainboard 1 dual-side is designed to parallel support edge 11 upwards, the band straight trough, makes when the dress thin product, support bar 2 can be installed, ceiling 3 can directly be piled up neatly dress, and is promptly firm, can save the shove charge space again, improves one time batch; At dress height during, can on mainboard two support edges 11, insert and support bar 2 that product adapts is adorned boat, gone into stove greater than the product of 1 liang of support edge of mainboard, 11 height.

Support bar 2 can be propped up last layer side's plate 1 again, makes product and top boat bottom maintenance certain distance in the boat; In the second short groove 22 of 2 same ends of support bar of ceiling 2 insertions and in the first short groove 13 of plate support edge, the side of stretching into 11; not only strengthened boat intensity, but also make product dress boat after form the protection that four limits are surrounded, guarantee that boat can not toppled over or drop out to the product in the boat in transfer process.

Ceiling 3 tops are lower than support bar 2 upper surfaces, bottom is higher than product placed side 14 on the mainboard 1, promptly do not maintain a certain distance d with boat bottom and upper strata boat bottom section ₁, d ₂Both protected the not large-area hydrogen that directly is subjected to of product to wash away, and made not only atmosphere in boat but also can form upper and lower convection current, make forming agent can be smooth and easy, taken away by hydrogen completely and get rid of; can not cause the generation of phenomenons such as product carburizing and peeling, improve product quality.
