Technical Field

[0001] The utility model relates to the technical field of heat treatment equipment for workpieces, in particular to heat treatment equipment for workpieces. Background Art

[0002] The existing heat treatment equipment has a common structure of a push rod type, that is, a push rod is used to push the workpiece into the furnace body, such as the prior art with patent number: CN219297588U; another type uses a mesh belt type to push the workpiece into the furnace body, such as the prior art with patent number: CN103160655A; although the above two methods can complete the transportation of the workpiece, due to the push rod type heat treatment equipment, when the workpiece enters the furnace body, the push rod needs to be pulled out, otherwise the doors on both sides of the furnace body will not close tightly; at the same time, the mesh belt of the mesh belt type heat treatment equipment is continuous, and after the door body is closed, a certain gap needs to be reserved between the mesh belt and the door body, otherwise the door body and the mesh belt bracket will produce friction that affects the service life of the mesh belt and the door body, especially, it is difficult for the door body to completely seal the furnace body.

DETAILED DESCRIPTION

[0018] Embodiments of the present utility model are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present utility model, and should not be construed as limitations on the present utility model. In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "upper surface", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the present utility model.

[0019] See also Figure 1-5 The utility model provides an embodiment: a heat treatment equipment for a workpiece, comprising a heating furnace 2, a cooling chamber 3 is provided on one side of the heating furnace 2, and an isothermal furnace 5 is provided on one side of the cooling chamber 3; rollers 7 for conveying the workpiece are provided inside the heating furnace 2, the cooling chamber 3 and the isothermal furnace 5, and the rollers 7 are rotated by a driving member 9 provided outside to cause the workpiece to pass through the heating furnace 2, the cooling chamber 3 and the isothermal furnace 5 in sequence; door bodies 10 are provided on both sides of the heating furnace 2 and the isothermal furnace 5, and lifting mechanisms 11 are provided on the tops of the heating furnace 2 and the isothermal furnace 5, and the lifting mechanisms 11 are used to cause the door bodies 10 to move upward or downward.

[0020] In summary, since the rollers 7 are used to transport the workpieces, and there are gaps between the rollers 7, while ensuring the transport of the workpieces, there is a gap to facilitate the lifting and lowering of the door body 10; specifically, when the door body is opened, it is convenient for the workpiece to enter the furnace body; when the door body is closed, the furnace body can be sealed; so that the door body 10 seals the workpiece inside the furnace body to ensure the heat processing efficiency of the furnace body on the workpiece. In addition, the rollers 7 are evenly distributed on the route of the workpiece movement, and the rollers 7 are used to carry the workpiece. Compared with the push rod type, there is no need to push the workpiece in and out. Compared with the mesh belt type, the structural strength of the rollers 7 is greater and the load capacity is stronger; thus solving the problem that the existing equipment adopts a push rod type or mesh belt structure, which makes it inconvenient to use and has a weak load capacity, and also solves the problem that the door body is not closed tightly, causing the heat source to radiate outward.

[0021] Specifically, the lifting mechanism 11 includes a motor 13, a reducer 14 and a winding wheel 15 linked to the motor 13; the output shaft of the reducer 14 is linked to the winding wheel 15 to drive the door body 10 to move upward or downward. Therefore, the lifting and lowering of the door body 10 can be realized automatically. Since the workpiece can be transported by the roller 7 and the door body 10 can be automatically lifted and lowered, the automation degree of the equipment is further improved.

[0022] In addition, since the cooling chamber 3 is connected to the cooling fan 6 through a pipeline, the workpiece is heated in the heating furnace 2 to complete the austenite homogenization stage of the workpiece, and then enters the cooling chamber to quickly transfer the workpiece to the rapid cooling stage, and then the workpiece is quickly transferred from the austenitizing temperature to the isothermal treatment temperature stage. Its specific structure can be referred to the prior art.

[0023] On the basis of the above scheme, since a fan 12 is also provided inside the isothermal furnace 5, and the airflow is caused to circulate in the isothermal furnace 5 through the blades on the fan 12, the temperature generated by the heating tube inside the isothermal furnace 5 can be evenly dispersed inside the furnace body, so that each surface of the workpiece in the furnace body can have a uniform exchange with the temperature inside the isothermal furnace 5.

[0024] Furthermore, since a feeding mechanism 1 is provided on a side of the heating furnace 2 away from the cooling chamber 3, and a discharging mechanism 4 is provided on a side of the isothermal furnace 5 away from the cooling chamber 3, the workpiece can smoothly enter the heating furnace 2, and can also be guided to smoothly flow out of the isothermal furnace 5. By setting the feeding mechanism 1 and the discharging mechanism 4, the distance between the user and the furnace body can be expanded to reduce the impact of the heat source on the operator.

[0025] Specifically, the feeding mechanism 1 has the same structure as the discharging mechanism 4 , and the feeding mechanism 1 includes a frame 16 , and a guide roller 17 having the same structure as the roller 7 is laid on the frame 16 .

[0026] Furthermore, transmission wheels 8 are provided at both ends of the guide roller 17 and the roller 7, and the driving member 9 is linked to the transmission wheel 8 through a transmission belt; wherein the transmission belt is preferably a chain, and the driving member 9 is preferably a motor.

[0027] To summarize, the user only needs to place the workpiece on the feeding mechanism 1, prompting the driving member 9 to prompt the guide roller 17 to rotate, so as to realize the transportation of the workpiece into the heating furnace 2; when the workpiece is heat treated, the workpiece flows to the discharging mechanism 4, prompting the driving member 9 to prompt the guide roller 17 to lead the workpiece out of the isothermal furnace 5.

[0028] Based on this, the provision of the feeding mechanism 1 and the discharging mechanism 4 not only expands the gap between the worker and the furnace body, but also facilitates the lifting of the workpiece onto the feeding mechanism 1 or the lifting of the workpiece from the discharging mechanism 4 .

[0029] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
