Abstract

A blank heating device having a heating furnace is provided and includes a plurality of heating members that heat a blank and a support fixture disposed within the heating furnace to support the blank. Further a transporting component is disposed beneath the support fixture and integrally displaces the support fixture and the blank to increase heating density of the blank. Consequently, a divisional heating occurs based on a size of the blank, which is a material for hot stamping, to improve heating density of the blank. Accordingly, marketability of a material is improved and a preheating time and heat loss is minimized. As a result, work convenience is improved and a consumption amount of energy is reduced.

First claim

What is claimed is:

1. A blank heating device, comprising:
a heating furnace that includes a plurality of heating members configured to heat a blank;
a support fixture disposed within the heating furnace to support the blank; and
a transporting component disposed beneath the support fixture and configured to integrally displace the support fixture and the blank to increase heating density of the blank,
wherein the heating member includes:
a lamp configured to generate heat by near infrared ray to omni-directionally radiate the heat; and
a reflecting plate disposed above the lamp to reflect heat radiated in an upward direction from the lamp to a downward direction, and

wherein the reflecting plate is formed in a parabolic shape which is convex in the upward direction to enable heat reflection in the downward direction,
wherein the heating furnace includes:
a plurality of pipes coupled to an upper portion of the heating furnace to discharge compressed air through nozzles and arranged in front-back direction;
a compressor coupled to the plurality of pipes to supply the compressed air to the plurality of pipes; and
a plurality of fans disposed within an interior upper surface of the heating furnace to circulate the compressed air discharged through the nozzles and arranged in the front-back direction and the left-right direction, and
wherein the plurality of fans is disposed between the plurality of pipes based on the front-back direction.

2. The blank heating device according to claim 1 , wherein the support fixture is formed of a ceramic material to prevent damage by heat of the heating members.

3. The blank heating device according to claim 1 , wherein the heating furnace includes a plurality of cooling members configured to cool the heating members.

4. The blank heating device according to claim 1 , wherein the heating furnace includes a first surface that is openable, and a lift configured to inject or extract the blank into or from the support fixture is disposed within the heating furnace.

5. A blank heating device, comprising:
a heating furnace configured to heat a blank by including a plurality of heating members including a lamp configured to omni-directionally radiate heat by near infrared ray, and a reflecting plate disposed above the lamp to reflect heat radiated in an upward direction from the lamp to a downward direction, wherein the reflecting plate is formed in a parabolic shape which is convex in the upward direction;
a support fixture disposed within the heating furnace to support the blank, and formed of a ceramic plate material to prevent heat transfer of the heating members and damage by heat of the heating members;
a transporting component disposed beneath the support fixture and configured to integrally displace the support fixture and the blank to increase heating density of the blank; and
a plurality of cooling members disposed within the heating furnace to cool the heating members,
wherein the heating furnace includes:
a plurality of pipes coupled to an upper portion of the heating furnace to discharge compressed air through nozzles and arranged in front-back direction;
a compressor coupled to the plurality of pipes to supply the compressed air to the plurality of pipes; and
a plurality of fans disposed within an interior upper surface of the heating furnace to circulate the compressed air discharged through the nozzles and arranged in the front-back direction and the left-right direction, and
wherein the plurality of fans is disposed between the plurality of pipes based on the front-back direction.

6. The blank heating device according to claim 5 , wherein the heating furnace include a first surface which is openable, and a lift configured to inject or extract the blank into or from the support fixture within the heating furnace.
