Description
Technical Field
The present invention relates to a hot forming apparatus, in particular a hot forming apparatus for metal materials provided with a hot forming chamber.
Background
In the existing metal material thermoforming equipment provided with the thermoforming chamber, heat is transferred to a part to be processed after heat is generated by heating equipment (for example, electric heating equipment arranged in a lower platform) arranged in the thermoforming chamber, so that the part to be processed is heated to a desired temperature value. The heat transfer media relied upon for the above heat transfer process primarily include metal components such as the lower platen that are in direct contact and the gaseous media within the thermoforming chamber. Due to the limited heat transfer rate of the heat transfer medium, the temperature of the part to be processed away from the heating device often increases at a different rate than the temperature of the part to be processed adjacent to the heating device, which has a series of adverse effects. Therefore, it is necessary to take measures to reduce the difference in the temperature increase rate between different regions of the member to be processed.

Detailed Description
The technical solution of the present invention will be described in detail below with reference to the embodiments shown in the drawings.
Fig. 1 shows a first embodiment of the invention, in which the thermoformed chamber portion is shown in cross-section to present the specific structure of this embodiment. As can be seen in fig. 1, the thermoforming apparatus includes a thermoforming chamber 118. A first outlet port 101 and a first inlet port 108 are provided in one side wall of the thermoforming chamber 118. A first air duct 104 is provided outside the side wall of the thermoforming chamber 118. The first air duct 104 is an air passage communicating the first air outlet 101 and the first air inlet 108. A first blower 106 is also provided on the first air duct 104. Adjacent to the first outlet 101, the first air duct 104 is provided with a first outlet passage of the thermoforming chamber (i.e. the passage in which the valve 102 is located), and a first inlet passage of the thermoforming chamber (i.e. the passage in which the valve 105 is located). A valve 103 is arranged in the first air duct 104 between the first inlet passage of the thermoforming chamber and the first outlet passage of the thermoforming chamber. A first heat-preserving chamber 107 is provided on the outer side wall of the thermoforming chamber 118, the first air duct 104 and the first air blower 106 are both provided in the first heat-preserving chamber 107, and a blower motor (not shown) for driving the first air blower 106 is provided outside the first heat-preserving chamber 107, so as to facilitate heat dissipation of the blower motor.
A second inlet 117 and a second outlet 110 are provided on the opposite side wall of the thermoforming chamber 118 to the side wall where the first outlet 101 is located. A second air duct 114 is provided on the outer wall of the thermoforming chamber 118. The second air duct 114 is an air passage communicating the second air inlet 117 and the second air outlet 110. A second blower 115 is also provided to the second air duct 114. A second exhaust passage of the thermoforming chamber (i.e. the passage where the valve 111 is located) and a second intake passage of the thermoforming chamber (i.e. the passage where the valve 113 is located) are provided at the second air duct 114 adjacent to the second air outlet 110. A valve 112 is provided in a second air passage 114 between the second inlet passage of the thermoforming chamber and the second outlet passage of the thermoforming chamber. A second heat-insulating chamber 116 is disposed on the outer wall of the thermoforming chamber 118, the second air duct 114 and the second blower 115 are disposed in the second heat-insulating chamber 116, and a blower motor (not shown) for driving the second blower 115 is disposed outside the second heat-insulating chamber 116, so as to facilitate heat dissipation of the blower motor. The valves in the embodiments shown in fig. 1 and 2 may be manual valves, pneumatic or electric valves. The manual valve is safe and reliable and has low cost. Pneumatic valves and electric valves are more beneficial to realizing automatic control.
Fig. 2 shows a second embodiment of the present invention, which differs from the first embodiment shown in fig. 1 in that an exhaust pipe 201 is provided in the first exhaust passage and an exhaust pipe 202 is provided in the second exhaust passage. Other differences are also in the on-off state of the valves. In fact, the embodiment shown in fig. 1 and the embodiment shown in fig. 2 show two operating states of the thermoforming apparatus of the invention. The following describes the working states shown in fig. 1 and fig. 2 in detail, respectively, to further illustrate the technical solution of the present invention.
As shown in fig. 1, the valves 102 and 105 are in a closed state and the valve 103 is in an open state. At this time, the thermoforming chamber 118 is in a temperature-rising state, and the first blower 106 is in an operating state, so that the gas in the thermoforming chamber 118 enters the first air duct 104 from the first air outlet 101, passes through the first blower 106, and returns to the thermoforming chamber 118 from the first air inlet 108. It can be seen that the gas circulation process described above creates a gas circulation flow within the thermoforming chamber 118, which allows the temperature to more quickly reach a uniform temperature throughout the various regions within the thermoforming chamber 118. The middle part of the mold 109, which is far away from the heating device (for example, a heating pipe arranged in a platform below the mold 109), can exchange heat with the gas medium with higher temperature, which is beneficial to reducing the temperature rise difference between the part and other parts.
The circulation of the gas in the thermoforming chamber 118 can be achieved by only the operation of the first blower 106, which achieves the object of the present invention. As shown in fig. 1, when the second blower 115 is further activated, the air in the thermoforming chamber 118 is driven to enter the second air duct 114 from the second air outlet 110, passes through the second blower 115, and then returns to the thermoforming chamber 118. When both the first blower 106 and the second blower 115 are in operation as shown in fig. 1, the amount of circulating gas in the thermoforming chamber 118 per unit time is increased, further accelerating the temperature uniformity process. In addition, as can be seen from the perspective of fig. 1, a three-dimensional coordinate system is established for the space in the thermoforming chamber 118, and the coordinate axes of the three-dimensional coordinate system include the coordinate axis in the direction of gravity (vertical direction in fig. 1), so that the arrangement order of the projection of the first air inlet 108 on the coordinate axis and the projection of the first air outlet 101 on the coordinate axis is the same as the arrangement order of the projection of the second air outlet 110 on the coordinate axis and the projection of the second air inlet 117 on the coordinate axis. I.e. vertically in fig. 1, the first intake vent 108 is below the first outlet vent 101, and correspondingly the second outlet vent 110 is below the second intake vent 117. This arrangement, with the first inlet 108 substantially opposite the second outlet 110 and the first outlet 101 substantially opposite the second inlet 117, creates convection between the first inlet 108 and the second outlet 110 and convection between the first outlet 101 and the second inlet 117, thereby creating a substantially full range of gas flow within the thermoforming chamber 118 and increasing the rate at which the ambient temperature of each section is uniform.
Fig. 2 illustrates another operational condition of the structure of fig. 1, namely, a reduced temperature condition within the thermoforming chamber 118. At this time, the valves 102 and 105 are opened, and the valve 103 is closed. The first blower 106 is activated, and air outside the thermoforming chamber 118 enters the thermoforming chamber 118 through the thermoforming chamber first air inlet passage via the first blower 106 and the first air inlet 108, so as to cool the mold 109. The outside air introduced into the thermoforming chamber 118 increases the pressure in the thermoforming chamber 118, and drives the gas (originally high-temperature gas) in the thermoforming chamber 118 into the thermoforming chamber first exhaust passage through the first air outlet 101, and then out through the exhaust pipe 201. This allows external cryogenic air to enter the thermoforming chamber 118 continuously for heat exchange with the mold 109. The heated air after heat exchange is exhausted through the exhaust pipe 201. This process allows the temperature within the thermoforming chamber 118 to be rapidly reduced so that the thermoforming apparatus can be cooled at a greater range of cooling rates.
In the cooling state shown in fig. 2, the valve 112 is closed, the valves 111 and 113 are opened, and the second blower 115 is activated. The air outside the thermoforming chamber 118 enters the thermoforming chamber 118 through the second air inlet passage of the thermoforming chamber via the second blower 115 and the second air inlet 117, and cools the mold 109. The outside air entering the thermoforming chamber 118 increases the pressure inside the thermoforming chamber 118, and drives the gas (originally high temperature gas) inside the thermoforming chamber 118 into the second exhaust passage of the thermoforming chamber through the second air outlet 110, and then out through the exhaust pipe 202. Activation of the second blower 115 accelerates the cooling process within the thermoforming chamber 118.
Fig. 3 shows a left side view of the thermoforming apparatus shown in fig. 1. As can be seen from fig. 3, two first air ducts 104 are provided, and first air blowers 106 are respectively matched to the two first air ducts 104. Other arrangement manners of the two first air ducts 104 are the same as those described in fig. 1, and are not described again here. The following description of fig. 1 will be made for the portions not referred to. The two first air ducts 104 are provided with two pairs of first air outlets 101 and first air inlets 108 on the wall of the corresponding thermoforming chamber 118, so that two sets of circulating air can be formed in the thermoforming chamber 118, and the two sets of circulating air are provided on two sides of the mold 109 respectively, for example, by reasonably setting the positions of the two sets of circulating air (by adjusting the positions of the first air outlets 101 and the first air inlets 108), so as to improve the efficiency. The two first air ducts 104 are respectively provided with two first heat preservation chambers 107 with matching first air blowers 106. The first blower motor 301 shared by the two first blowers 106 is arranged between the two first heat preservation chambers, so that the cost is saved, the working efficiency and the heat dissipation efficiency of the motor are improved, and the space can be saved.
It should be noted that the above-mentioned embodiments are only preferred embodiments of the present invention, and the scope of the present invention is not limited thereby, and the present invention may be modified in materials and structures, or replaced with technical equivalents, in the constructions of the above-mentioned various components. Therefore, structural equivalents made by using the description and drawings of the present invention or by directly or indirectly applying to other related arts are also encompassed within the scope of the present invention.
