[0016] The present invention provides a trolley-type forging heating furnace with a trolley sealing structure. It has the following beneficial effects:
[0017] (1) The present invention uses a U-shaped groove plate, an electric telescopic rod, a horizontal plate, a convex plate, a T-shaped rod, a concave frame, a rubber strip, a semi-arc block and an arc-shaped spring sheet in conjunction with a rectangular plate. The spring on the concave frame is compressed.

[0018] (2) The present invention arranges an air opening device so that the L-shaped short rod, vertical plate, convex strip, L-shaped vertical rod, baffle, round rod and short column cooperate with the L-shaped air pipe. The convex strip opens the smoke inlet of the convex plate during the upward movement, and the baffle opens the smoke outlet of the convex plate during the upward movement. When the heating furnace performs heat treatment on the workpiece, the smoke for heating the workpiece enters the smoke inlet of the convex plate, and the smoke in the convex plate is blocked by the convex strip. The smoke enters the through groove of the car body from the smoke outlet, allowing the smoke carrying heat to heat the car body, preventing the smoke from the furnace body from staying only on the upper part when the trolley sealing structure is closed, causing heat energy waste. When the equipment completes the heat treatment of the workpiece, the short column quickly leaves the L-shaped air pipe, allowing the smoke in the convex plate to be quickly discharged from the L-shaped air pipe, preventing the accumulation of smoke in the trolley sealing structure from causing equipment aging and corrosion.
[0019] (3) The present invention arranges the smoke filter device so that the long ring block, the connecting plate, the convex frame, the filter, the vertical ring and the long rod cooperate with the disc, and the filter moves to the bottom of the smoke inlet of the convex plate, so that the smoke is filtered by the filter while entering the smoke inlet of the convex plate, thereby preventing the impurities carried by the smoke from being attached to the sealing structure of the trolley and causing poor operation of the equipment. In addition, the disc lifts up the filter during the upward movement, causing the filter to bulge, thereby preventing the filter pores in the sealing structure of the trolley from being blocked and causing poor thermal circulation of the equipment.

[0032] An anti-deformation component is provided on the top surface of the concave frame 11, and the anti-deformation component includes a semi-arc block 13, which is fixed on the top surface of the concave frame 11.

The rectangular plate 15 is arranged on the front and back of the concave frame 11, and the semi-arc block 13 is pressed against the front and back of the concave frame 11, so that the concave frame 11 is not easily deformed during the extrusion process, so as to avoid the concave frame 11 being easily squeezed and deformed when the trolley sealing structure is closed, resulting in poor use effect.
[0033] When in use, the staff places the workpiece to be heated on the car body 3, and then pushes the car body 3 into the furnace body 1. The car body 3 moves to the left on the U-shaped guide rail of the furnace body 1. When the car body 3 is completely moved into the furnace body 1, the heating module 2 on the car body 3 is started, and the heating module 2 begins to heat up. The heating module 2 heats the workpiece in the car body 3. Since the trolley-type forging heating furnace is in the process of heat treating the workpiece, the smoke when the workpiece is heated is easy to overflow from the gap above the heating furnace. When the car body 3 is completely moved into the furnace body 1, the furnace body 1 supports the U-shaped groove plate 4, and the electric telescopic rod 7 on the U-shaped groove plate 4 is started. The telescopic end of the electric telescopic rod 7 moves downward, and the telescopic end of the electric telescopic rod 7 drives the horizontal plate 8 to move downward, and the horizontal plate 8 drives the convex plate 9 to move downward. When the convex plate 9 moves to the bottom, the convex plate 9 The plate 9 blocks the right side of the furnace body 1 to reduce the overflow of smoke and dust during the heat treatment of the furnace body 1. At the same time, the cross plate 8 drives the spring to move downward, the spring on the cross plate 8 drives the concave frame 11 to move downward, the concave frame 11 drives the T-shaped rod 10 to move downward, and the concave frame 11 drives the rubber strip 12 to move downward.

Under the elastic force of the spring, the rubber strip 12 is tightly pressed against the edge of the furnace body 1, so that the gap between the furnace body 1 and the convex plate 9 is blocked, preventing the gap from overflowing smoke and dust when the equipment is closed, thereby avoiding the problem of smoke and dust overflowing due to gaps above the equipment when the trolley sealing structure is closed.

The L-shaped short rod 51 is fixed in the middle of the top surfaces of the two T-shaped rods 10, the vertical plate 52 is fixed on the right side of the two L-shaped short rods 51, the vertical plate 52 is slidably mounted on the inner wall of the strip groove of the convex plate 9, the convex strip block 53 is fixed on the bottom surface of the vertical plate 52, the L-shaped vertical rod 54 is fixed on the bottom surface of the convex strip block 53, the baffle 55 is fixed on the left bottom of the two L-shaped vertical rods 54, the convex strip block 53 is slidably arranged on the inner wall of the convex plate 9, and the convex strip block 53 It is arranged on the right side of the smoke inlet of the convex plate 9, the baffle 55 is slidably arranged on the right side of the inner wall of the convex plate 9, the baffle 55 is arranged on the right side of the smoke outlet of the convex plate 9, the convex strip 53 opens the smoke inlet of the convex plate 9 during the upward movement, and the baffle 55 opens the smoke outlet of the convex plate 9 during the upward movement. When the heating furnace performs heat treatment on the workpiece, the smoke heating the workpiece enters the smoke inlet of the convex plate 9, the smoke in the convex plate 9 is blocked by the convex strip 53, and the smoke enters the through groove of the car body 3 from the smoke outlet of the convex plate 9, so that the smoke carrying heat heats the car body 3, so as to avoid the smoke burning in the furnace body 1 staying only above when the trolley sealing structure is closed, causing heat energy waste.

The edges of the top surfaces of the two short columns 57 are set as rounded corners. The L-shaped air pipe 58 is fixedly installed on the inner walls of the two circular holes of the cross plate 8. The inner wall of the L-shaped air pipe 58 is on the movement trajectory of the short column 57. When the equipment completes the heat treatment of the workpiece, the short column 57 quickly leaves the L-shaped air pipe 58, allowing the smoke in the convex plate 9 to be quickly discharged from the L-shaped air pipe 58, thereby avoiding the accumulation of smoke in the sealing structure of the trolley and causing aging and corrosion of the equipment.
[0037] A smoke filtering device 6 is provided at the bottom of the outer wall of the air opening device 5, and the smoke filtering device 6 includes a long ring block 61, a connecting plate 62, a convex frame 63 and a filter 64.

[0038] The smoke filter device 6 also includes a vertical ring 65, a long rod 66 and a disc 67. The vertical ring 65 is fixed to the bottom of the side of the two long ring blocks 61 away from each other. The long rod 66 is slidably installed on the inner walls of the two vertical rings 65. The disc 67 is fixed on the top surface of the two long rods 66. The two discs 67 are located on the bottom surface of the filter screen 64. The disc 67 lifts up the filter screen 64 during the upward movement, so that the filter screen 64 produces a bulge to avoid the pores of the filter screen 64 in the trolley sealing structure from being blocked, resulting in poor thermal circulation effect of the equipment.
[0039] When the T-shaped rod 10 moves upward in the sliding hole of the horizontal plate 8, the T-shaped rod 10 drives the L-shaped short rod 51 to move upward, the L-shaped short rod 51 drives the vertical plate 52 to move upward, the vertical plate 52 drives the convex bar 53 to move upward, the convex bar 53 slides upward in the chamber of the convex plate 9, the convex bar 53 drives the L-shaped vertical rod 54 to move upward, the L-shaped vertical rod 54 drives the baffle 55 to move upward, so that the convex bar 53 opens the smoke inlet of the convex plate 9 during the upward movement, and the baffle 55 moves upward. During the movement, the smoke outlet of the convex plate 9 is opened. When the heating furnace performs heat treatment on the workpiece, the smoke from heating the workpiece enters the smoke inlet of the convex plate 9. The smoke in the convex plate 9 is blocked by the convex strip 53. The smoke enters the through groove of the car body 3 from the smoke outlet of the convex plate 9, allowing the smoke carrying heat to heat the car body 3 and preventing the smoke carrying heat from stagnating above the furnace body 1, thereby avoiding the problem of heat energy waste caused by the smoke from the combustion of the furnace body 1 only staying above when the trolley sealing structure is closed.
[0040] While the vertical plate 52 drives the convex bar 53 to move upward, the convex bar 53 drives the round rod 56 to move upward, and the round rod 56 drives the short column 57 to move upward. In the process of the short column 57 moving upward, the short column 57 slides into the L-shaped air pipe 58, so that the short column 57 is blocked in the L-shaped air pipe 58. When the equipment completes the heat treatment of the workpiece, the telescopic end of the electric telescopic rod 7 is reset, so that the short column 57 quickly leaves the L-shaped air pipe 58, and the smoke in the convex plate 9 is quickly discharged from the L-shaped air pipe 58, preventing the smoke in the equipment from accumulating in the convex plate 9, thereby avoiding the problem of equipment aging and corrosion caused by the accumulation of smoke in the trolley sealing structure.
[0041] While the convex bar 53 drives the L-shaped vertical rod 54 to move upward, the L-shaped vertical rod 54 drives the long ring block 61 to move upward, the long ring block 61 drives the connecting plate 62 to move upward, the connecting plate 62 drives the convex frame 63 to move upward, and the convex frame 63 drives the filter 64 to move upward, so that the filter 64 moves to below the smoke inlet of the convex plate 9, allowing the smoke to be filtered by the filter 64 while entering the smoke inlet of the convex plate 9, preventing impurities carried by the smoke from adhering to the equipment when the equipment is undergoing a thermal cycle, thereby avoiding the problem of impurities carried by the smoke adhering to the trolley sealing structure, causing poor equipment operation.
[0042] When the telescopic end of the electric telescopic rod 7 is reset, the long ring block 61 drives the vertical ring 65 to move downward, the vertical ring 65 drives the long rod 66 to move downward, and the long rod 66 drives the disc 67 to move downward. In the process of the long rod 66 moving downward, the long rod 66 contacts the convex plate 9. Under the action of the extrusion force, the long rod 66 slides upward in the vertical ring 65, and the long rod 66 drives the disc 67 to move upward, so that the disc 67 lifts up the filter screen 64 in the process of moving upward, so that the filter screen 64 is raised to prevent the pores of the filter screen 64 in the equipment from being blocked by impurities carried by the flue gas, thereby avoiding the problem of poor thermal circulation effect of the equipment caused by the pores of the filter screen 64 in the trolley sealing structure being blocked.
