[0029] Please refer to Figs. 1-3 A porous twisted tube heating furnace for heating workpieces 100 is provided in the embodiment, wherein the porous twisted tube heating furnace comprises:

[0030] A furnace body 1 is lifted by a support 11 and forms a gap;

[0031] A conveying mechanism 2 comprises a conveying track 21 and a lifting device 22, the conveying track 21 is arranged in the gap at the bottom of the furnace body 1, the conveying track 21 extends in a first direction, the lifting device 22 is installed on the conveying track 21, the conveying track 21 is used to drive the lifting device 22 to reciprocate in the first direction, and the top of the lifting device 22 is used to place the workpieces 100;

[0032] The lifting device 22 can reciprocate vertically along the first direction, and the bottom surface of the furnace body 1 is provided with a mounting hole 12, the hole diameter of the mounting hole 12 matches the maximum peripheral size of the workpiece 100 along the self-axis, so that when the transport track 21 drives the lifting device 22 to move to the preset position, the lifting device 22 can insert the workpiece 100 from the mounting hole 12 on the bottom surface of the furnace body 1 into the interior of the furnace body 1 and heat it.

[0033] Through the above structure, in use, the lifting device 22 is pre-stopped at the side close to the upstream of the furnace body 1, the operator only needs to place the workpiece 100 on the lifting device 22 of the transport mechanism 2, and then start the transport track 21 of the transport mechanism 2 to run, and make the transport track 21 drive the workpiece 100 on the lifting device 22 to move along the first direction until the horizontal position of the workpiece 100 matches the position of the mounting hole 12 on the bottom of the furnace body 1, and then the transport track 21 stops running, the lifting device 22 starts running, and drives the workpiece 100 on the top of the lifting device 22 to be lifted in the direction of the bottom of the furnace body 1, so that the workpiece 100 passes through the mounting hole 12, and finally the workpiece 100 is lifted and inserted into the interior of the furnace body 1, and then the fixing device in the interior of the furnace body 1 clamps the workpiece 100, or at the same time the lifting device 22 holds the workpiece 100, and starts the furnace body 1 to heat the workpiece 100, after the heating is completed, the lifting device 22 is restarted to run and falls, so that the workpiece 100 is removed from the furnace body 1, and is transported to the downstream direction of the furnace body 1 by the transport track 21. It is worth noting that the steps of placing the workpiece 100 on the lifting device 22, or taking the workpiece 100 away from the lifting device 22 can be realized by the mechanical arm arranged on the periphery of the furnace body 1. Fig. 2 The steps of placing the workpiece 100 on the lifting device 22, or taking the workpiece 100 away from the lifting device 22 can be realized by the mechanical arm arranged on the periphery of the furnace body 1.

[0034] In the above use process, since the workpiece 100 is inserted into the interior of the furnace body 1 from the mounting hole 12 on the bottom of the furnace body 1 by means of the transport mechanism 2, one mounting hole 12 corresponds to one workpiece 100, and one mounting hole 12 is equivalent to one separate furnace door, the so-called furnace door is in an open state by default, when the workpiece 100 is completely inserted, the so-called furnace door is equivalent to a completely closed state, at the same time, the size of the mounting hole 12 is smaller than the existing large-area furnace door, and the heat dissipation is less, which helps to save energy and avoid the problem of large and high heat dissipation of the existing furnace door. At the same time, by matching the mounting hole 12 with the self-axis of the workpiece 100, the positioning of the workpiece 100 can be better realized, the workpiece 100 is vertically installed on the top of the lifting device 22, which avoids the problem of setting one corresponding tool 12 for one workpiece 100, and helps to save cost, and the workpiece 100 is easier to be positioned and has a higher fault tolerance rate compared with the larger furnace door.

[0035] Further, the workpiece 100 is connected with the lifting device 22 through the mounting seat 3, the diameter of the mounting seat 3 matches the hole size of the mounting hole 12 on the bottom surface of the furnace body 1, and the mounting hole 12 is sealed by the periphery of the mounting seat 3 after the lifting device 22 inserts the workpiece 100 into the inside of the furnace body 1 from the mounting hole 12 on the bottom surface of the furnace body 1. Specifically, the mounting seat 3 is made of ceramic material, and after the mounting seat 3 is completely inserted into the mounting hole 12 of the furnace body 1, the mounting seat 3 actually functions as a plug body to tightly plug the connection between the furnace body 1 and the outside, thereby achieving the isolation between the inside and the outside. The mounting seat 3 made of ceramic material is heated together with the workpiece 100 in the furnace body 1 and has strong structural stability.

[0036] Further, the bottom of the mounting seat 3 is further provided with a flange portion 31, the bottom of the flange portion 31 has a groove, the top of the lifting device 22 has a key 221 matched with the position of the groove, and the flange portion 31 is used to be connected with the top of the lifting device 22. Specifically, the mechanical arm directly places the workpiece 100 mounted on the mounting seat 3 on the top of the lifting device 22, and since the flange portion 31 at the bottom of the mounting seat 3 has a flange portion, the flange portion can quickly be aligned with the key 221 and limit the mounting seat 3, thereby avoiding the sliding of the mounting seat 3 on the top of the lifting device 22.

[0037] Further, the transport track 21 is arranged in multiple parallel and spaced rows, and each row of the transport track 21 is provided with multiple lifting devices 22. The bottom surface of the furnace body 1 is provided with multiple mounting holes 12, and the multiple mounting holes 12 are arranged in a rectangular array. Through the above structure, the present embodiment constructs a multi-hole type twisted pipe heating furnace which can synchronously and simultaneously heat multiple workpieces 100. The multiple lifting devices 22 work alternately in front and back, thereby improving the use efficiency of the furnace body 1. As shown in the layout, Fig. 3 the layout can be matched with the flow line of the transport mechanism 2.

[0038] Further, the bottom of the furnace body 1 is provided with a spring buckle, and after the lifting device 22 inserts the workpiece 100 into the inside of the furnace body 1 from the mounting hole 12 on the bottom surface of the furnace body 1, the spring buckle locks the workpiece 100, so that the workpiece 100 does not separate from the furnace body 1. That is to say, after the lifting device 22 in the present embodiment is lifted into the inside of the furnace body 1, the furnace body 1 can lock the workpiece 100 or the mounting seat 3 and the flange portion 31 structure at the bottom of the workpiece 100 by means of the spring buckle, thereby achieving the complete sealing of the mounting hole 12 and avoiding the energy waste caused by heat leakage. Alternatively, during the heating process of the workpiece 100 locked in the furnace body 1, the corresponding lifting device 22 can leave and displace to the next group of workpieces 100 for carrying.

[0039] Further, the workpiece 100 in the above embodiment is arranged in an irregular twisted structure pipe, that is to say, the maximum hole size of the mounting hole 12 can meet the peripheral coverage of the twisted structure pipe.

[0040] The above disclosed is only the preferred feasible embodiment of the present application, and does not limit the patent application range of the present application, so that any equivalent technical change made by applying the content of the present application specification and drawings is included in the patent application range of the present application.

[0041] Each embodiment in the specification is described in a progressive manner, and the same or similar parts between each embodiment can be referred to each other, and each embodiment mainly describes the difference from other embodiments.

[0042] Although the present application is described through embodiments, it is known to those skilled in the art that there are many modifications and changes of the present application without departing from the spirit of the present application, and it is hoped that the attached embodiments include these modifications and changes without departing from the present application.
