Description

Technical Field

[0001] This utility model relates to the technical field of bolt heat treatment equipment, and in particular to a bolt production heat treatment device. Background Technology

[0002] Bolts, as key threaded fasteners in mechanical assembly, possess a detachable connection structure formed by their cylindrical thread and matching nut. In the heat treatment process, solid metal materials undergo a complete heating, holding, and cooling thermal processing flow; this technology has been widely used since the early days of metal processing technology. Traditional heat treatment equipment achieves its processing function through a box structure housing heating elements and a support frame. Operators must place the bolt workpiece on the support frame and start the heating program to complete the bolt processing.

[0003] While the above method can process bolts, it's important to note that the bolt surface is at a high temperature after heat treatment. At this point, using clamping tools for workpiece transfer presents a significant efficiency bottleneck. Whether unloading finished bolts or loading new workpieces, operators must rely on tools to clamp and transfer each piece individually. This operating mode not only leads to low production efficiency but also poses a serious risk of burns due to the heat radiation and conduction effects inside the high-temperature chamber. Furthermore, the continuous use of clamping tools further prolongs the production cycle. Utility Model Content

[0004] The purpose of this invention is to solve the problems in the prior art by proposing a bolt production heat treatment device that can load and unload bolts.

[0005] To achieve the above objectives, this utility model proposes a heat treatment apparatus for bolt production, comprising: a heat treatment chamber and a heat treatment component disposed within the heat treatment chamber, the heat treatment component being capable of heat treating the bolts.

[0006] Also includes:

[0007] Storage frames, wherein several storage frames are provided, and each storage frame is connected to the heat treatment chamber by a driven swing;

[0008] A sealing door and a push rod are provided. The sealing door is elastically slidably connected to the top surface of the storage frame, and the push rod is fixedly connected to the sealing door. One end of the push rod extends to the bottom of the storage frame, and the sealing door can be in contact with the top surface of the storage frame.

[0009] Guide frame one is inclined and fixedly connected to the heat treatment box, and one end of guide frame one extends outside the heat treatment box, while the top surface of guide frame one can be in contact with the bottom surface of push rod.

[0010] Preferably, the heat treatment box is inclinedly and fixedly connected to the guide frame two above the guide frame one. The guide frame two is located above the storage frame. The heat treatment box is elastically and slidably connected to the top surface of the guide frame two. The bottom surface of the sealing door three is fixedly connected to the connecting rod one. The connecting rod one is slidably connected to the guide frame two, and the top surface of the connecting rod one can be in contact with the top surface of the guide frame two.

[0011] Preferably, a sealing door four is slidably connected to the guide frame two, and a sliding rod is fixedly connected to the sealing door four. The sliding rod is elastically slidably connected to the guide frame two, and one end of the sliding rod extends outside the guide frame two. The sliding rod is arranged opposite to the top surface of the storage frame.

[0012] Preferably, an extension plate is fixedly connected to the sliding rod, and one end of the extension plate can be attached to the top surface of the storage frame.

[0013] Preferably, a movable frame is elastically slidably connected to the guide frame, and a connecting rod is fixedly connected to the movable frame. One end of the connecting rod is slidably connected to the guide frame, and a sealing door is fixedly connected to the connecting rod, which can be in contact with the top surface of the guide frame.

[0014] Preferably, the bottom surface of the second sealing door is provided with an inclined surface, which is in contact with the top surface of the first guide frame.

[0015] Preferably, an extension plate is fixedly connected to the second connecting rod, and one end of the extension plate can be attached to the bottom surface of the storage frame.

[0016] The beneficial effects of this utility model compared with the prior art are as follows:

[0017] 1. The cooperation between each elastic reset element and sliding component constitutes a fail-safe mechanism. The spring always provides pre-tension to the sealing door, ensuring that all openings are sealed during non-operational periods. This design not only eliminates heat radiation leakage but also reduces the safety hazards of traditional clamping operations. The entire device relies entirely on the spatial coordination and force transmission between mechanical components to complete the operation cycle. All actions from feeding to discharging originate from the kinetic energy conversion of the single-degree-of-freedom swing of the storage frame. There is no need for manual clamping tools to complete the feeding; simply inserting the bolts into the guide frame is sufficient, thus greatly increasing the feeding efficiency. Simultaneously, discharging is performed by swinging, eliminating the need for manual clamping tools to unload the bolts, thereby increasing the bolt discharging efficiency.

[0018] 2. A complete mechanical linkage system is constructed through the pendulum motion of the storage frame. First, the mechanical coupling between the swing mechanism and the sealing door realizes the automatic opening and closing function without power transmission. When the storage frame is driven by the motor to swing, its top and bottom surfaces trigger the movement of the sealing door in the guide frame area through the rigidly connected push rod and extension plate, respectively. This pure mechanical interlock ensures reliable sealing without manual intervention in high-temperature environments.

[0019] 3. The inclined guide frame and the tilt angle of the storage frame form a natural gravity slide. After the bolts are heat-treated, they can be discharged by their own weight. The whole process achieves fully mechanical flow of high-temperature workpieces through the precise coordination of the swing angle of the storage frame and the opening and closing stroke of the sealing door.

[0020] The features and advantages of this utility model will be described in detail through embodiments and accompanying drawings. Attached Figure Description

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0028] like Figures 1 to 2 A heat treatment apparatus for bolt production includes: a heat treatment chamber 1 and a heat treatment component 2 disposed inside the heat treatment chamber 1. The heat treatment component 2 is capable of heat treating bolts. The heat treatment component 2 mainly consists of heating rods, which are fixedly connected to the inner wall of the heat treatment chamber 1. The heating rods are used to heat the inner wall of the heat treatment chamber 1, thereby achieving heat treatment of the bolts.

[0029] The heat treatment device in this utility model also includes: several storage frames 3, a sealing door, a push rod 5, and a guide frame 6;

[0030] The storage frames 3 are all oscillatingly connected to the heat treatment chamber 1 by a motor. The motor is fixedly connected to the side wall of the heat treatment chamber 1, and its output shaft passes through the heat treatment chamber 1 and is fixedly connected to the storage frames 3, thus realizing the oscillation of the oscillating frames. When the bolts in the storage chamber need to be discharged, the motor drives the oscillating frames to oscillate. Since the sealing door 4 is elastically slidably connected to the top surface of the storage frame 3, and the push rod 5 is fixedly connected to the sealing door 4, with one end of the push rod 5 extending to the outside of the bottom of the storage frame 3, the sealing door 4 can be in contact with the top surface of the storage frame 3. The guide frame 6 is obliquely fixedly connected to the heat treatment chamber 1, with one end of the guide frame 6 extending outside the heat treatment chamber 1. The top surface of guide frame 6 can be in contact with the bottom surface of push rod 5. Therefore, storage frame 3 swings, causing the top surface of guide frame 6 to contact the bottom surface of push rod 5. At this time, storage frame 3 continues to swing, causing guide frame 6 to drive push rod 5 to move upward, thereby opening storage frame 3. Since storage frame 3 is in an inclined state, bolts will slide onto guide frame 6. Guide frame 6 guides the bolts, thereby realizing bolt discharge. It is worth mentioning that sealing door 4 is elastically slidably connected to the top surface of storage frame 3 by spring. The spring is fixedly connected inside storage frame 3, and one end is fixedly connected to sealing door 4, thus realizing the reset of sealing door 4.

[0031] Specifically, a second guide frame 7 is fixedly and inclined above the first guide frame 6 in the heat treatment chamber 1. The second guide frame 7 is located above the storage frame 3. A third sealing door 8 is elastically and slidably connected to the top surface of the second guide frame 7 in the heat treatment chamber 1. A first connecting rod 9 is fixedly connected to the bottom surface of the third sealing door 8. The first connecting rod 9 is slidably connected to the second guide frame 7. The bottom surface of the first connecting rod 9 can be in contact with the top surface of the storage frame 3. Therefore, when the bolts need to be loaded, the storage frame 3 swings upward, so that the top surface of the storage frame 3 contacts the bottom surface of the first connecting rod 9. The connecting rod 9 moves and drives the connecting rod 9 to move. Once the connecting rod 9 moves, it will drive the sealing door 8 to move, causing the sealing door 8 to move upward. Once the sealing door 8 moves upward, the guide frame 7 opens. At this time, the bolts in the guide frame 7 will slide onto the storage frame 3, thereby realizing the loading of the storage frame 3. The sealing door 8 is elastically slidably connected by a spring. The spring is fixedly connected inside the guide frame 7, and one end is fixedly connected to the sealing door 8, thereby achieving the reset of the sealing door 8.

[0032] Specifically, a sealing door 10 is slidably connected to the guide frame 2 7, and a sliding rod 11 is fixedly connected to the sealing door 4 10. The sliding rod 11 is elastically slidably connected to the guide frame 2 7, and one end of the sliding rod extends outside the guide frame 2 7. The sliding rod 11 is positioned opposite to the top surface of the storage frame 3. An extension plate 12 is fixedly connected to the sliding rod 11. One end of the extension plate 12 can be in contact with the top surface of the storage frame 3. Therefore, when the storage frame 3 contacts the extension plate 12, the storage frame 3 will push the extension plate 12 to move upward. Once the extension plate 12 moves upward, the extension plate 12 will drive the sliding rod 11 to drive the sealing door 4 10 to move upward, thereby opening the heat treatment box 1. At this time, personnel can put the bolts into the guide frame 2 7, thereby guiding the bolts to enter the storage frame 3. It is worth mentioning that the sliding rod 11 is elastically connected by a spring. The spring is fixedly connected inside the guide frame 2 7, and one end is fixedly connected to the sliding rod 11, which can realize the reset of the sliding rod 11.

[0033] Specifically, a movable frame 13 is elastically slidably connected to the guide frame 6, and a connecting rod 14 is fixedly connected to the movable frame 13. One end of the connecting rod 14 is slidably connected to the guide frame 6, and a sealing door 15 is fixedly connected to the connecting rod 14. The sealing door 15 can be in contact with the top surface of the guide frame 6, and the bottom surface of the sealing door 15 is provided with an inclined surface 16, which is in contact with the top surface of the guide frame 6. An extension plate 17 is fixedly connected to the connecting rod 14, and one end of the extension plate 17 can be in contact with the bottom surface of the storage frame 3. Therefore, by the contact between the bottom surface of the storage frame 3 and one end of the extension plate 17, the storage frame 3 pushes the extension plate 17 to move. Once the extension plate 17 moves, the extension plate 17 drives the connecting rod 14 to move, which in turn drives the movable frame 13 to drive the sealing door 15 to move, thereby opening the heat treatment box 1. At this time, the bolts enter the guide frame 6 for guidance, so that the bolts are discharged to the outside, thereby achieving bolt discharge.

[0034] Working principle of this utility model:

[0035] The core working principle originates from the swing mechanism of storage frame 3. When the motor drives the output shaft to rotate, it directly causes storage frame 3 to perform a pendulum motion within the heat treatment chamber 1. The top surface of storage frame 3 and the sealing door 8 in the area of ​​guide frame 2 7 are mechanically interlocked via connecting rod 1 9. When storage frame 3 swings upward, its top surface pushes connecting rod 1 9 upward, causing sealing door 3 8 to overcome spring resistance and open the feeding port of guide frame 2 7. The bolt to be processed then slides into storage frame 3 along the inclined guide frame 2 7. After feeding is completed, storage frame 3 swings back, causing connecting rod 1 9 to disengage, and sealing door 3 8 automatically resets and closes under the action of the spring.

[0036] Heating rods fixed to the inner wall of the container continuously heat the sealed space, and the storage frame 3, swinging to a horizontal position, heats the bolts. When discharge is required, the storage frame 3 swings downward, and the push rod 5 at its bottom makes mechanical contact with the top surface of the guide frame 6. As the swing angle increases, the inclined surface of the guide frame 6 continuously pushes the push rod 5 upward, driving the sealing door 4 away from the discharge port of the storage frame 3 through a rigid connection. At this time, the storage frame 3 is in an inclined state, and the heat-treated bolts slide into the guide frame 6 under the action of gravity. When the storage frame 3 swings back, the push rod 5 disengages, and the sealing door 4 re-closes under the action of the spring.

[0037] When the storage frame 3 swings down, its bottom surface presses against the extension plate 17, which, through the connecting rod 14, causes the sealing door 15 to open the discharge channel of the guide frame 6. The inclined surface 16 of the sealing door 15 and the guide frame 6 form a wedge fit, which can ensure the sealing and also form a guide ramp when opened.

[0038] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
