Description

Technical Field

[0001] The invention relates to the technical field of fastener processing heat treatment quenching, in particular to a quenching device for fastener production. Background Art

[0002] Fasteners, as a kind of mechanical parts used for fastening connections, have a wide range of applications and a very high usage rate. The requirements for their various performances during use are also different, and the types of fasteners required for different requirements or application scenarios are also different.

[0003] When producing fasteners, especially high-strength fasteners, it is often necessary to quench the fastener products or raw materials. During quenching, a large amount of high-temperature steam will be generated, which will not only waste quenching water, but also cause the environment of the production workshop to become humid. Because quenching needs to be performed under high temperature, the quenching pool will not be placed too far away from the heating treatment equipment. In this way, a large amount of water vapor will remain in the workshop, which will affect the normal progress of other processes. It will also affect the production workers in the workshop. Because the temperature of the workshop itself is very high and the working environment is already poor, it will further deteriorate the working environment after it becomes humid.

[0004] Therefore, we propose a quenching device, which is mainly used in fastener production to solve the problem of generating high-temperature steam during the quenching process, wasting water resources and worsening the working environment. Summary of the Invention

[0005] The object of the present invention is to provide a quenching device for fastener production to solve the problems raised in the above background technology.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A quenching device for fastener production includes a quenching box, a boss structure, a slide, a sliding plate, a cover plate, a blower fan, an air inlet and a cooling return channel. The boss structure is arranged on the right side of the top of the quenching box, the slide is opened on both sides of the top of the boss structure, the sliding plate is inserted into the inner cavity of the slide, the bottom of the cover plate is fixedly connected to the top of the sliding plate, the blower fan is installed on the left side wall of the quenching box, the air inlet is opened on the left side surface of the boss structure, and the cooling return channel is opened on the inner wall of the air inlet.

[0008] Preferably, the top of the cooling reflux channel is connected to the inner cavity of the air inlet, the cooling reflux channel is an L-shaped channel, and the other end of the cooling reflux channel is connected to the bottom of the inner cavity of the quenching box.

[0009] Preferably, a blocking diaphragm is fixedly connected to one end of the cooling reflux channel communicating with the inner cavity of the quenching box, and the blocking diaphragm is a four-valve plastic sheet.

[0010] Preferably, a rotating drum is installed on the right side of the inner wall of the quenching box through a bearing and a rotating shaft, a plug hole is opened on the outer wall of the rotating drum, a plug is plugged into the inner cavity of the plug hole, and the end of the plug away from the rotating drum is fixedly connected to a rotating plate.

[0011] Preferably, the rotating plate is a hollow plate, and filter holes are provided on both sides of the rotating plate. The two sides of the rotating plate with filter holes are fixed to the rotating plate by bolts.

[0012] Preferably, the filter holes are tapered holes, and the small-diameter ends of the filter holes are all facing the inner cavity of the rotating plate.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The quenching device for fastener production, through the design and use of the quenching box, cover plate, blower fan, air inlet, and cooling return channel, can quickly and timely blow away the high-temperature steam generated during the quenching of the fasteners and cool it back, effectively solving the problems of wasting cooling water for quenching and the adverse effects of high-temperature steam on the production environment.

[0015] 2. The quenching device for fastener production, through the design and use of the rotating drum, rotating plate and filter holes, when processing high-temperature steam, the rotating plate that comes into contact with the high-temperature steam is in a low-temperature state each time, which can achieve the effect of quickly condensing the high-temperature steam. At the same time, when the high-temperature steam is refluxed, the high-temperature steam refluxed at the bottom can also blow up the debris particles settled at the bottom, and then recycle them through the rotation of the rotating plate, thereby purifying the cooling water used for quenching and improving the utilization time of the cooling water.

[0016] 3. The quenching device for fastener production, when the rotating drum and the rotating plate rotate, can also drive the cooling water at the bottom to flow, so as to flush the high-temperature fasteners. On the one hand, it can speed up the quenching work of the fasteners, and on the other hand, it can also flush away the debris to be detached generated by the quenching of the fasteners.

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example 1:

[0024] A quenching device for fastener production includes a quenching box 1, a boss structure 2, a slide 3, a sliding plate 4, a cover plate 5, a blower fan 6, an air inlet 7 and a cooling return channel 8. The boss structure 2 is arranged on the right side of the top of the quenching box 1, the slide 3 is opened on both sides of the top of the boss structure 2, the sliding plate 4 is inserted into the inner cavity of the slide 3, the bottom of the cover plate 5 is fixedly connected to the top of the sliding plate 4, the blower fan 5 is installed on the left side wall of the quenching box 1, the air inlet 7 is opened on the left side surface of the boss structure 2, and the cooling return channel 8 is opened on the inner wall of the air inlet 7.

[0025] Furthermore, the top of the cooling reflux channel 8 is connected to the inner cavity of the air inlet 7 , the cooling reflux channel 8 is an L-shaped channel, and the other end of the cooling reflux channel 8 is connected to the bottom of the inner cavity of the quenching box 1 .

[0026] In this embodiment, Figure 1 、 Figure 2 and Figure 3 As shown, when quenching fasteners, first pull the cover plate 5 to move and cover part of the quenching box 1, then turn on the blower fan 6 to generate strong wind, and then put the frame or other container containing high-temperature fasteners into the quenching box 1. At this time, the high-temperature steam generated instantly is blown toward the air inlet 7 under the action of the strong wind, and due to the obstruction of the cover plate 5, it will not diffuse to the external environment. Then the high-temperature steam enters the cooling return channel 8 and finally flows back to the cooling water in the quenching box 1, realizing the recycling of water resources. At the same time, it can also prevent the high-temperature steam from spreading everywhere, causing a bad working workshop environment.

[0027] Furthermore, a blocking diaphragm 9 is fixedly connected to one end of the cooling reflux channel 8 communicating with the inner cavity of the quenching box 1 , and the blocking diaphragm 9 is a four-valve plastic sheet.

[0028] The main function of the sealing diaphragm 9 of the valve structure is to reduce the amount of cooling water reflux inside the quenching box 1. It will be flushed open only under the action of strong thrust steam. Even if some cooling water refluxes when the blowing stops, it can be pushed out of the cooling reflux channel 8 when the next high-temperature steam enters. The high-temperature steam is preliminarily cooled in the cooling reflux channel 8, and after entering the quenching box 1, it comes into contact with the cooling water for final condensation.

[0029] Example 2:

[0030] A rotating drum 10 is installed on the right side of the inner wall of the quenching box 1 through a bearing and a rotating shaft. A plug hole is opened on the outer wall of the rotating drum. A plug 11 is plugged into the inner cavity of the plug hole. The end of the plug 11 away from the rotating drum 10 is fixedly connected to a rotating plate 12.

[0031] Furthermore, the rotating plate 12 is a hollow plate, and filter holes 13 are provided on both sides of the rotating plate 12 . The two sides of the rotating plate 12 with the filter holes 13 are fixed to the rotating plate 12 by bolts.

[0032] Furthermore, the filter holes 13 are tapered holes, and the small-diameter ends of the filter holes 13 face the inner cavity of the rotating plate 12 .

[0033] In this embodiment, Figure 1-4 As shown, based on Example 1, the strong wind from the blower fan 6 will first hit the rotating plate 12, causing the rotating plate 12 and the drum 10 to rotate. Secondly, the high-speed flowing high-temperature steam will also hit the rotating plate 12, causing it to rotate.

[0034] When rotating, the bottom of the rotating plate 12 rotates upward, that is, the rotating plate 12 in the cooling water contacts the high-temperature steam. The temperature difference between the two is large, which realizes the first cooling of the high-temperature steam and the condensation recovery part. This action occurs continuously, and the rotating plate 12 in contact each time is in a low-temperature state.

[0035] When the rotating plate 12 rotates, it can filter out suspended or sedimentary particles and enter the inner cavity of the rotating plate 12 through the filter holes 13. At the same time, when it leaves the cooling water surface, it can also filter and absorb the oil residue left by the fastener quenching.

[0036] The conical filter holes 13 allow oil and particle debris to enter the rotating plate 12 easily, but are relatively difficult to exit. In this way, the filtered particles and oil can remain in the inner cavity of the rotating plate 12, while the cooling water can flow out of the filter holes 13 smoothly.

[0037] Finally, the rotating plate 12 can be directly pulled out after being used for a period of time, and the parts with filter holes 13 on both sides can be disassembled to collect impurities, oil and grease, and then cleaned and reused.

[0038] In the description of the present invention, it should also be noted that, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to mechanical connections or electrical connections; they may refer to direct connections or indirect connections through an intermediate medium; and they may refer to internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0039] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
