Description

Technical Field

[0001] The utility model relates to the technical field of fastener production, in particular to a quenching device for fastener production. Background Art

[0002] Fasteners are a type of mechanical parts used for fastening and connection and are extremely widely used. Fasteners are widely used in industries including energy, electronics, electrical appliances, machinery, chemicals, metallurgy, molds, hydraulics, etc. Various fasteners can be seen on various machinery, equipment, vehicles, ships, railways, bridges, buildings, structures, tools, instruments, chemicals, instruments and supplies, etc. They are the most widely used mechanical basic parts; among them, metal fasteners, such as bolts, need to be quenched during the production process. The fasteners are heated to above the critical temperature, kept warm for a certain period of time, and then cooled at a cooling rate greater than the critical cooling rate to obtain an unbalanced structure dominated by martensite (there are also bainite or single-phase austenite as needed), thereby completing the quenching operation. Quenching is the most widely used process method in steel heat treatment technology.

[0003] For example, the patent with announcement number CN218521293U announces a quenching fixture for shaft fasteners, including a first base frame, a second placement block, a washer and a second base frame, the first base frame is fixedly installed with a second fixed block on the side close to the second placement block, the second fixed block is fixedly installed with a second stop block on the side close to the second placement block, and the second base frame is fixedly installed with a guide column on the side close to the second placement block. The purpose of conveniently flipping the washer is achieved by setting a steel cable, a first fixed block, a toothed plate and a first gear. As the interval between the second stop block and the first stop block increases, the second stop block and the first stop block gradually contact the inner ring of the washer, squeeze the inner ring of the washer, and squeeze the washer through the inside to achieve the purpose of fixing the washer, avoiding the rotation of the washer when flipping, thereby achieving the purpose of conveniently flipping the washer.

[0004] However, the quenching device in the above technology still has the following problems:

[0005] When the multiple washers on it are pushed deeper into the quenching furnace through the first and second stops, since the multiple washers are not fixed in position, when the first and second stops have a certain inclination angle, the multiple washers will slide to the same end at the same time, and then cause the multiple washers to collide with each other. The washers in quenching will gradually become softer, and the collision may cause the washers to deform. If the washers are squeezed outward for fixing by the first and second stops, the washers after quenching may be squeezed and deformed, which is not conducive to the shape stability of the washers in quenching. Utility Model Content

[0006] In view of the deficiencies of the prior art, the utility model provides a quenching device for fastener production, which can fix multiple washers while avoiding deformation of washers caused by external forces, thereby preventing the washers from falling into the quenching furnace.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a quenching device for fastener production, comprising a base frame and two symmetrically arranged clamping rods installed on the base frame, a plurality of washers are sleeved on the two clamping rods, a through hole is opened on the side of the two clamping rods away from the base frame, a control rod is slidably connected in the two through holes, a plurality of flip holes are opened on the side of the two clamping rods away from each other, the plurality of flip holes are connected with the same group of through holes, a flap is connected in the plurality of flip holes, the plurality of flaps are respectively located between two adjacent washers, the same group of flaps are connected with the same group of control rods, and the two control rods are connected with a control assembly at one end close to the base frame.

[0008] Furthermore, both sides of the flap are rotatably connected to both sides of the flip hole via a rotating shaft.

[0009] Furthermore, a rotation groove is formed at one end of the flap close to the control rod, a flip block is rotatably connected in the rotation groove via a rotating shaft, and the other end of the flip block is fixedly connected to the control rod.

[0010] Furthermore, the control component includes an electric push rod and a push block. The clamping rod is close to one end of the base frame and is provided with a control groove connected to the through hole on the side close to the flip hole. The electric push rod is fixedly connected to the side of the control groove close to the base frame, the telescopic end of the electric push rod is connected to the push block, the push block is slidably connected to the control groove, and one end of the push block is fixedly connected to the control rod.

[0011] Furthermore, a slide groove is provided on one side of the push block close to the electric push rod, a slider is slidably connected in the slide groove, and the telescopic end of the electric push rod is fixedly connected to the side of the slider away from the slide groove.

[0012] Furthermore, the slider is a T-shaped structure.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] See also Figure 1 - Figure 5 A quenching device for fastener production comprises a base frame 1 and two symmetrically arranged clamping rods 2 mounted on the base frame 1, a plurality of washers 3 are sleeved on the two clamping rods 2, a through hole 201 is opened on the side of the two clamping rods 2 away from the base frame 1, a control rod 4 is slidably connected in the two through holes 201, a plurality of flip holes 202 are opened on the side of the two clamping rods 2 away from each other, the plurality of flip holes 202 are connected with the same group of through holes 201, a flap 5 is connected in the plurality of flip holes 202, the plurality of flaps 5 are respectively located between two adjacent washers 3, the same group of flaps 5 are connected with the same group of control rods 4, and the two control rods 4 are connected with a control component at one end close to the base frame 1.

[0023] like Figure 1 - Figure 5 As shown, a quenching device for fastener production in the utility model is similar in structure to an existing quenching device for fastener production, such as a shaft fastener quenching fixture disclosed in the patent with announcement number CN218521293U. The main improvement of the utility model is that the user can separate the multiple washers 3 on the fixture, thereby avoiding collision between the multiple washers 3 during the quenching process, which in turn causes the washers 3 to deform. Figures 1 to 5As shown, when the quenching device for fastener production in the utility model is in use, multiple washers 3 that need to be quenched are placed between the multiple flip holes 202 respectively, and then the control rod 4 is driven by the control component to move in the through hole 201, and then the flaps 5 in the multiple flip holes 202 are driven to tilt up from the flip holes 202. At this time, the multiple tilted flaps 5 can separate the multiple washers 3. During the quenching process, when the washers 3 slide on the two clamping rods 2, the flaps 5 between two adjacent washers 3 are blocked between the two washers 3, thereby preventing the washers 3 from sliding on the clamping rod 2 for too long a distance, reducing the sliding speed of the washers 3, and preventing the washers 3 from colliding with each other and deforming after sliding.

[0024] like Figure 3 and Figure 4 As shown, both sides of the flap 5 are rotatably connected to both sides of the flip hole 202 via the rotating shaft. The flap 5 can be flipped and lifted in the flip hole 202 to separate the gasket 3, or flipped into the flip hole 202, so that the gasket 3 can be put on the two clamping rods 2 or removed from the two clamping rods 2.

[0025] like Figure 2 and Figure 3 As shown, a rotation groove 501 is formed at one end of the flap 5 close to the control rod 4, and a flip block 6 is rotatably connected to the rotation groove 501 through a rotating shaft, and the other end of the flip block 6 is fixedly connected to the control rod 4. When the flap 5 flips in the flip hole 202 through the rotating shaft, the control rod 4 moves forward and backward to drive the flip block 6 to move, and the flip block 6 drives the flap 5 to flip up and down through the rotating shaft.

[0026] like Figure 1 - Figure 5 As shown, the control assembly includes an electric push rod 7 and a push block 8. A control slot 203 communicating with the through hole 201 is provided on one side of the clamping rod 2 close to the base frame 1 and close to the flip hole 202. The electric push rod 7 is fixedly connected to the side of the control slot 203 close to the base frame 1. The telescopic end of the electric push rod 7 is connected to the push block 8. The push block 8 is slidably connected to the control slot 203. One end of the push block 8 is fixedly connected to the control rod 4. The electric push rod 7 drives the push block 8 to slide back and forth in the control slot 203, and then drives the control rod 4 to move back and forth in the through hole 201. The control rod 4 that moves back and forth drives the flap 5 to flip up and down in the flip hole 202 through the flip block 6.

[0027] like Figure 5As shown, a slide groove 801 is provided on the side of the push block 8 close to the electric push rod 7, a slider 9 is slidably connected in the slide groove 801, and the telescopic end of the electric push rod 7 is fixedly connected to the side of the slider 9 away from the slide groove 801. When the electric push rod 7 drives the push block 8 to move forward and backward, the push block 8 is driven by the slider 9. At this time, as the multiple flaps 5 flip up and down, the control rod 4 moves forward and backward in the through hole 201, and also moves up and down to a certain extent. At this time, while the slider 9 drives the push block 8 to move forward and backward, the slider 9 can move up and down through the slide groove 801, thereby avoiding the bending of the control rod 4 during movement, making the control rod 4 move forward and backward more smoothly.

[0028] like Figure 5 As shown, the slide block 9 is a T-shaped structure. The slide block 9 is designed as a T-shaped structure, which can ensure that it is always connected and slidable with the slide groove 801 on the push block 8 and will not fall off.

[0029] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention.
