Description

Technical Field

[0001] The utility model relates to the technical field of trolley type furnaces, in particular to a device for improving the heating and sealing effect of an aluminum alloy trolley type furnace. Background Art

[0002] Aluminum alloys are generally heated by table-top furnaces. The trolley furnace is a national standard energy-saving periodic operation furnace with an ultra-energy-saving structure. The bottom of the furnace is a movable trolley. Before heating, the trolley is loaded outside the furnace, and the heating element is placed on a special pad. The traction mechanism then pulls the trolley into the furnace for heating. After heating, the traction mechanism pulls the trolley out of the furnace for unloading.

[0003] The movement of the trolley is provided by the motor through the worm gear reducer and chain drive, and is equipped with an electromagnetic brake for appropriate adjustment. The trolley is installed with a chromium-manganese-nitrogen heat-resistant steel furnace bottom plate or a 1200℃ silicon carbide furnace bottom plate to carry the workpiece. Due to the gap between the trolley and the furnace body, the sealing effect in the furnace body is defective, resulting in heat loss, and the heat is conducted into the bottom of the trolley, heating the components at the bottom, which may cause damage to the components, thus affecting the movement function of the trolley. Utility Model Content

[0004] In order to overcome the disadvantage that the sealing in the furnace is defective, the utility model provides a device for improving the heating and sealing effect of an aluminum alloy trolley type furnace.

DETAILED DESCRIPTION

[0020] Although the present invention may be described with respect to a specific application or industry, those skilled in the art will recognize the broader applicability of the present invention. Those of ordinary skill in the art will recognize that terms such as: above, below, upward, downward, etc. are used to describe the drawings and do not represent limitations on the scope of the present invention as defined by the appended claims. Any numerical designations such as: first or second are merely exemplary and are not intended to limit the scope of the present invention in any way.

[0021] Embodiment: A device for improving the heating and sealing effect of an aluminum alloy trolley furnace, such as Figure 1 and Figure 2 As shown, it includes a trolley 1, a furnace body 101, a furnace door 102, a heat-resistant plate 103 and a sealing assembly. The trolley 1 is slidably connected to the bottom of the furnace body 101, the furnace door 102 is slidably connected to the front end of the furnace body 101, and the heat-resistant plate 103 is slidably connected to the trolley 1 for placing a heated workpiece. A sealing assembly for improving the sealing inside the furnace is arranged on the trolley 1.

[0022] like Figure 1-Figure 3 As shown, the sealing assembly includes a spreading rod 2, a first spring 201, a guide rod 202, a movable plate 3, an extrusion plate 31, a sealing plate 4 and a second spring 5. Two movable plates 3 and two extrusion plates 31 are slidably connected on the trolley 1, and each movable plate 3 is located outside the extrusion plate 31. The movable plate 3 and the extrusion plate 31 on the same side are slidably connected to each other. The sealing plate 4 is slidably connected to the outside of the movable plate 3 through a sliding rod fixed thereto. The second spring 5 is sleeved on the sealing plate 4. On the sliding rod, one end is welded to the outside of the moving plate 3, and the other end is welded to the inside of the sealing plate 4. A spreading rod 2 is slidably connected between the two extrusion plates 31. The outer end of the spreading rod 2 is a curved block, and the spreading rod 2 is provided with a convex block that cooperates with the triangular groove of the extrusion plate 31. The guide rod 202 is welded in the middle of the trolley 1 and is located in the groove in the middle of the spreading rod 2. A first spring 201 is sleeved on the guide rod 202, one end of which is connected to the guide rod 202, and the other end is welded in the groove of the spreading rod 2.

[0023] The staff puts the workpiece to be heated on the heat-resistant plate 103, and then controls the trolley 1 to enter the furnace body 101. After it is fully entered, the furnace door 102 is closed downward. At this time, the curved block at the outer end of the support rod 2 is still located at the edge of the furnace body 101, so that when the furnace door 102 is downward and in contact with the support rod 2, the support rod 2 is pushed to move inward, squeezing the first spring 201, and the extrusion plate 31 is moved to both sides through the protrusion, thereby pushing the movable plate 3 and the sealing plate 4 to move to both sides. After the sealing plate 4 contacts the inner wall of the furnace body 101, it fits tightly and compresses the second spring 5, thereby completing the sealing of the transmission assembly under the trolley 1 and isolating the heat. After the workpiece is heated, the furnace door 102 is opened, and the resilience of the first spring 201 and the second spring 5 is used to reset the support rod 2, the movable plate 3, the extrusion plate 31 and the sealing plate 4.

[0024] like Figure 1 and Figure 2 As shown, it also includes a connecting rod 6, a gear set 7 and a threaded rod 8. The connecting rod 6 is rotatably connected to the extrusion plate 31. A cross groove 9 is opened at the end of the connecting rod 6. The threaded rod 8 is rotatably connected in the extrusion plate 31. The threaded rod 8 is threadedly connected to the moving plate 3. A gear set 7 is provided at the intersection of the connecting rod 6 and the threaded rod 8.

[0025] For a larger furnace body 101, a long plate can be used to rotate the connecting rod 6 through the cross groove 9, thereby driving the threaded rod 8 to rotate through the gear set 7, so that the movable plate 3 moves outward, changing its initial position, and thereby shortening the distance between the sealing plate 4 and the inner wall of the furnace body 101, thereby meeting the needs of a larger furnace body 101 and shortening the distance to optimize the sealing effect when the sealing plate 4 is damaged.

[0026] like Figure 5 As shown, a gasket 13 is also included, and the gasket 13 is fixedly connected to the outer side of each sealing plate 4.

[0027] The gasket 13 can optimize the sealing effect of the sealing plate 4 , reduce the contact and loss between the sealing plate 4 and the furnace body 101 , and extend the service life of the sealing plate 4 .

[0028] like Figure 5 As shown, it also includes a bent rod 10 and a buckle 11. The buckle 11 is welded to the trolley 1, and the bent rod 10 is buckled on the buckle 11.

[0029] like Figure 5 As shown, a protective cover 12 is also included, and the protective cover 12 is slidably connected to the end of the connecting rod 6.

[0030] The connecting rod 6 can be easily rotated by means of the curved rod 10 with a cross protrusion, and the curved rod 10 is directly connected to the buckle 11, which is convenient for taking and placing. The cross groove 9 of the connecting rod 6 can also be protected by the protective cover 12 to prevent foreign objects from entering, so that the connecting rod 6 will not slip when rotating.

[0031] The above embodiments are provided for persons familiar with the art to implement or use the present invention. Personnel familiar with the art can make various modifications or changes to the above embodiments without departing from the utility model concept of the present invention. Therefore, the protection scope of the present invention is not limited to the above embodiments, but should be the maximum scope of the innovative features mentioned in the claims.
