Description

Technical Field

[0001] The utility model relates to the technical field of tempering furnace doors, in particular to a tempering furnace door fixing structure. Background Art

[0002] The tempering furnace is mainly used to temper metal parts, or to anneal and age heat treat aluminum alloy castings, pistons and other parts. It is widely used in metallurgical casting and other industries. When the tempering furnace is in use, a kiln door will be opened to seal the furnace body, so that the kiln passage is isolated from the outside world, to prevent cold air from entering the kiln, aggravating the gas stratification in the kiln, and increasing the temperature difference between the upper and lower parts. The kiln door plays a vital role in the use of the tempering furnace. Due to the large demand for workpiece casting, more tempering furnaces need to be installed in the factory, so multiple sets of kiln doors are needed. At the beginning of the use of the tempering furnace, the staff is required to transport the required kiln doors from the production site to the tempering furnace plant, and then install them on the tempering furnace one by one. However, in the actual transportation of the kiln doors, in order to reduce the floor space occupied by the kiln doors, the staff directly stacked more kiln doors on the truck. Since the kiln doors are stacked directly, when the truck encounters an uneven road section, the kiln doors will be offset by force, resulting in the stacked kiln doors colliding with each other, causing the kiln doors to deform under force, thereby affecting the sealing of the kiln doors in subsequent use.

[0003] In order to solve the above problems, Chinese patent application No.: 202223419862.7 discloses a tempering furnace kiln door fixing structure, including a door frame, wherein two groups of door bodies are symmetrically hinged inside the door frame, and the four face angles inside the door frame are provided with accommodating grooves, and the inside of the accommodating grooves are all engaged with connecting blocks, and the bottom end of the connecting block is vertically connected to a limiting rod, and a docking groove is provided at a position corresponding to the limiting rod on the upper side of the door frame. The utility model is provided with a connecting block and a limiting rod to prevent the door frame from being offset during transportation, thereby ensuring the subsequent normal use of the door frame, so as to improve the reliability of the device during use, and is provided with a movable plate and a limiting block. During use, the limiting block and the movable plate cooperate with each other to embed the connecting block in the accommodating groove, thereby realizing the storage of the connecting block, so as to ensure the subsequent normal use of the device.

[0004] It can be seen that in the prior art, the door frame will not be offset during transportation through the cooperation of the connecting block and the limit rod. However, since the transport vehicle may encounter uneven roads during transportation, or may be affected by external factors and perform emergency braking, the kiln door inside the transport vehicle may be affected by external forces, causing two adjacent kiln doors to collide with each other. The existing structure for fixing the kiln door is not convenient for buffering the force of the impact. If the impact force is too large, the fixing structure of the kiln door may easily break.

The existing structure of fixing the kiln door is not convenient for buffering the force of the impact. When the impact force is too large, the fixing structure of the kiln door is broken.

[0027] In the prior art, the door frame will not be offset during transportation by the cooperation of the connecting block and the limiting rod. However, during transportation, the transport vehicle may encounter uneven roads or be affected by external factors and perform emergency braking, which may cause the kiln door inside the transport vehicle to be affected by external forces and cause two adjacent kiln doors to collide with each other. The existing structure for fixing the kiln door is not convenient for buffering the force of the impact. If the impact force is too large, the fixing structure of the kiln door is easily broken. Therefore, after research, a fixing structure for the kiln door of a tempering furnace is provided. When in use, a slide groove 1 is opened on the outside of the door body, and two sliders are used to slide in the slide groove 1, so that the positioning rod rotates in the threaded hole, and the buffer plate is pulled upward to move the buffer plate out of the slide groove 1. The buffer plate is lifted by the positioning rod so that the plug plate is plugged into the slot of the other door body, the two door bodies are separated, and the two door bodies are kept at a certain distance. When one of the door bodies is hit, the slider squeezes the elastic member 1 to buffer the impact force, thereby solving the above defects.

[0028] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0029] Please refer to Figures 1 to 5 The embodiment of the utility model provides a tempering furnace door fixing structure, including a door body 1, a slot 11 is provided on one side of the door body 1, a slide groove 12 is provided on the other side of the door body 1, and a buffer component 2 is movably installed in the slide groove 12.

[0030] like Figure 4As shown, the buffer assembly 2 includes a pair of sliders 21 slidably arranged at both ends of the slide groove 12, the upper ends of the sliders 21 are U-shaped, the two sliders 21 are respectively hinged to the lower ends of the two connecting blocks 22, and the upper ends of the two connecting blocks 22 are respectively hinged to the two sides of the buffer plate 23. In the natural state, the connecting blocks 22 are tilted downward and are accommodated in the slide groove 12 with the buffer plate 23. In the use state, the chain sliders 21 are away from the inner wall of the slide groove 12, and the connecting blocks 22 are tilted, so that the buffer plate 23 is moved out of the slide groove 12.

[0031] In order to prevent the slider 21 from being separated from the slide groove 12, a slide groove 13 is provided at both ends of the slide groove 12, and a protrusion 24 is provided on the lower side of the slider 21, which is slidably connected to the slide groove 13 through the protrusion 24, thereby enhancing the stability of the connection between the slider 21 and the slide groove 12.

[0032] In addition, in order to achieve the purpose of buffering the impact force, one side of the protrusion 24 is connected to one end of the elastic member 25, and the other end of the elastic member 25 is connected to the inner wall of the slide groove 13. The sliding of the slider 21 in the slide groove 12 causes the protrusion 24 to squeeze the elastic member 25, and the elastic effect of the elastic member 25 buffers the impact force.

[0033] like Figure 2 As shown, a fixing mechanism 3 is connected to the middle portion of the buffer assembly 2 , one end of the fixing mechanism 3 is inserted into the interior of the slide slot 12 , and the other end of the fixing mechanism 3 is plugged into and matched with the slot 11 .

[0034] Specifically, the fixing mechanism 3 includes a pair of buffer rods 34 fixedly arranged on the buffer plate 23, and a baffle 35 is provided on the outside of the buffer rod 34, and the baffle 35 is connected to one side of the buffer plate 23 to increase the contact area between the buffer rod 34 and the buffer plate 23. A positioning rod 31 is provided on the outside of one end of the buffer rod 34 for sliding. The positioning rod 31 is used to fix the buffer plate 23 to prevent the elastic member 25 from pulling the buffer plate 23 into the slide groove 12. Therefore, an external thread 32 is provided on the outside of the positioning rod 31, and a pair of threaded holes 14 are opened in the center of the slide groove 12. The positioning rod 31 is threadedly connected to the threaded hole 14 through the external thread 32 to achieve the purpose of fixing the buffer plate 23.

[0035] In order to enhance the buffering of the impact force, the inside of the positioning rod 31 is connected to the buffer rod 34 by using the second elastic member 33, and the buffering effect is enhanced by the elastic buffering of the second elastic member 33.

[0036] Among them, a sliding hole 36 is opened at the other end of the buffer rod 34, and a fixing rod 39 is slidably installed in the sliding hole 36, and a positioning groove 37 is opened on the inner wall of the sliding hole 36. A fixing block 391 is provided at one end of the fixing rod 39. When in use, the fixing rod 39 is slid out of the sliding hole 36 to extend the use length of the plug plate 392. When the plug plate 392 is inserted into the slot 11, the spacing between the two door bodies 1 can be maintained to prevent collision between the two adjacent door bodies 1, and the sliding connection between the fixing block 391 and the positioning groove 37 effectively prevents the fixing rod 39 from detaching from the sliding hole 36.

[0037] Furthermore, in order to prevent the fixing rod 39 from sliding into the sliding hole 36 when the plug plate 392 is hit, a locking groove 38 is opened at one end of the positioning groove 37 close to the plug plate 392, and the locking groove 38 is connected to the positioning groove 37, and one end of the fixing rod 39 is rotatably connected to one side of the plug plate 392. At this time, the fixing rod 39 can be rotated to make the fixing block 391 enter the positioning groove 37, effectively avoiding the fixing rod 39 from accidentally sliding when in use.

[0038] The elastic member 1 25 and the elastic member 2 33 are preferably made of metal springs, damping springs or other materials that are in line with the art.

[0039] In summary, the working principle of the tempering furnace kiln door fixing structure of the utility model embodiment is as follows: when in use, the positioning rod 31 is rotated outward, so that the positioning rod 31 pulls the buffer plate 23 upward, and the fixing rod 39 is slid out of the sliding hole 36 to extend the use length of the plug plate 392, and the fixing rod 39 is rotated to make the fixing block 391 enter the locking groove 38. At this time, the plug plate 392 is inserted into the slot 11 of another door body 1. When the door body 1 is hit, the plug plate 392 carries the fixing rod 39 and the buffer rod 3 4 moves, so that the buffer rod 34 presses the elastic member 2 33, and the impact force is buffered by the elasticity of the elastic member 2 33. At the same time, the buffer plate 23 is affected by the force, and the buffer plate 23 moves downward to prompt the slider 21 to slide toward the inner wall of the slide groove 12, so that the protrusion 24 presses the elastic member 1 25, and the elastic member 1 25 plays a buffering role against the force through elastic contraction. Secondly, when the door body 1 is installed on the tempering furnace for use, the plug plate 392 can be used as a handle to facilitate the opening of the door body 1.

[0040] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
