Description

Technical Field

[0001] This utility model relates to the field of heat treatment tooling technology, and in particular to a heat treatment tooling for fasteners. Background Technology

[0002] Fasteners are mechanical parts used to fasten two or more parts (or components) together into a whole. They are widely used in various machines, equipment and structures. Their main function is to ensure the reliability, stability and safety of the connection and to prevent the parts from loosening, separating or shifting during use. In the production and processing of fasteners, they need to be heat treated to improve their strength.

[0003] Specialized tooling is required when heat treating fasteners, such as a material frame. Fasteners are placed inside the material frame for storage, and then the material frame and fasteners are placed together in a quenching furnace for heat treatment. However, because the fasteners will accumulate inside the material frame, they will fit together tightly with small gaps. This makes the process of hot air penetrating into the gaps slow, resulting in uneven heating of the fasteners and affecting the heat treatment efficiency. Utility Model Content

[0004] The technical problem to be solved by this utility model is that after the fasteners are put into the material frame, they will accumulate with each other, resulting in a tight fit between the fasteners and a small gap. This makes the process of hot air penetrating into the gaps slow, resulting in uneven heating of the fasteners and affecting the heat treatment efficiency of the fasteners.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a fastener heat treatment fixture, comprising: a material frame for storing fasteners; and a separating device disposed inside the material frame, wherein the separating device is used to separate and store the fasteners piled up inside the material frame to avoid the fasteners from piling up and sticking together.

[0006] Preferably, the separating device includes: a bearing seat, which is fixedly connected to the inner wall of the material frame, wherein the surface of the bearing seat away from the material frame is provided with threads; and a placement disc, which is sleeved on the bearing seat, wherein the inner wall of the placement disc is provided with evenly distributed holes.

[0007] The effect achieved by the above-mentioned components is as follows: By setting up a separating device, the fasteners are first evenly placed on the placement tray. At this time, the placement tray is manually moved, causing the placement tray to move the fasteners. When the placement tray moves to the shaft seat, the placement tray is placed inside the material frame. Then, multiple placement trays are loaded with fasteners and sequentially placed on the shaft seat, so that multiple placement trays are stacked on the shaft seat. Under the action of multiple placement trays, the stored fasteners are stored in layers inside the material frame, avoiding excessive accumulation or tight contact between fasteners. This completes the auxiliary storage of fasteners, reduces the excessive accumulation of fasteners after they are directly put into the material frame, which leads to tight contact between fasteners and small gaps. This results in a slower process of hot air penetrating the gaps, causing uneven heating of the fastener surface, thus improving the heat treatment efficiency of the fasteners.

[0008] Preferably, a rubber ring is fixed to the side of the placement disk near the shaft seat, wherein the rubber ring is annularly sleeved on the shaft seat.

[0009] The effect achieved by the above components is as follows: by setting the rubber ring, the placement plate and the bearing can be separated, reducing the collision and wear between the bearing and the placement plate. At the same time, it can also separate two adjacent placement plates, reducing the contact wear between the two placement plates.

[0010] Preferably, the inner wall of the placement tray is fixed with a plurality of protrusions, and the plurality of protrusions are arranged at equal intervals.

[0011] The effect achieved by the above components is as follows: by setting up protrusions, the protrusions can support the fasteners, and there is a certain gap between the fasteners and the inner wall of the placement tray, thereby improving the flow of hot air between the fasteners and the inner wall of the placement tray.

[0012] Preferably, a plurality of rectangular holes are provided on one side of the placement tray, and partitions are slidably connected to the inner walls of the plurality of rectangular holes.

[0013] The effect achieved by the above components is as follows: by setting up partitions, personnel can insert multiple partitions into the storage tray through rectangular holes, and use the partitions to divide the storage area inside the storage tray into multiple small areas, thereby storing fasteners in different areas and further improving the classification and separation of fasteners.

[0014] Preferably, the inner wall of the placement tray is fixedly connected to a handle, wherein the inner side of the handle is provided with multiple anti-slip protrusions.

[0015] The effect achieved by the above-mentioned components is that by setting a handle, a point of leverage can be provided for personnel to manually move the placement tray, so that personnel can move the placement tray by manually moving the handle, thereby improving the convenience and stability of manually moving the placement tray.

[0016] Preferably, a cover plate is fitted onto the surface of the shaft seat, and a threaded ring is threaded onto the end of the shaft seat away from the material frame, wherein the cover plate is adapted to the size and shape of the placement tray.

[0017] The effect achieved by the above components is as follows: by setting the cover plate, after multiple placement trays are sequentially placed on the bearing seat, the cover plate is manually placed on the bearing seat so that the cover plate is in contact with the surface of the uppermost placement tray. At this time, the screw hole ring is manually rotated so that the screw hole ring moves up and down along the surface of the bearing seat. During the movement, the screw hole ring presses the cover plate to fix the position of the cover plate, so that the cover plate covers the placement tray and covers and seals the opening of the placement tray, reducing the possibility of fasteners falling out of the uppermost placement tray during transportation.

[0018] Preferably, a plurality of auxiliary blocks are fixed to the surface of the screw hole ring, wherein the surface of the auxiliary blocks is rectangular.

[0019] The effect achieved by the above components is that by setting up auxiliary blocks, the hands can be stopped, reducing the chance of slipping when personnel manually rotate the screw hole ring.

[0020] The beneficial effects of this utility model are:

[0021] By setting up a separator, fasteners can be stored in layers and separated inside the material frame, avoiding excessive accumulation or tight contact between fasteners. This reduces the problem of fasteners being too tightly packed together after being directly put into the material frame, resulting in tight contact between fasteners and small gaps. This slows down the process of hot air penetrating the gaps, causing uneven heating of the fastener surface and improving the heat treatment efficiency of the fasteners. Attached Figure Description

[0030] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0031] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] Example 1, Figure 1-6 The fastener heat treatment fixture shown includes: a material frame 1 for storing fasteners; and a separator 2 disposed inside the material frame 1, wherein the separator 2 is used to separate and store the fasteners piled up inside the material frame 1 to prevent the fasteners from piling up and sticking together.

[0033] Figure 2-6 The separating device 2 shown includes: a shaft seat 21, which is fixedly connected to the inner wall of the material frame 1, wherein the end of the shaft seat 21 away from the material frame 1 is threaded; and a placement disc 22, which is sleeved on the shaft seat 21, wherein the inner wall of the placement disc 22 has evenly distributed holes. By setting the separating device 2, fasteners are first evenly placed on the placement disc 22. Then, the placement disc 22 is manually moved, causing the placement disc 22 to move the fasteners. When the placement disc 22 moves to be sleeved on the shaft seat 21, the placement disc 22 is placed inside the material frame 1. Then, multiple placement discs 22 are installed. After the fasteners are inserted, they are sequentially placed on the shaft seat 21, so that multiple placement discs 22 are stacked on the shaft seat 21. This allows the stored fasteners to be stored in layers inside the material frame 1 under the action of multiple placement discs 22, avoiding excessive stacking or tight contact between fasteners. This completes the auxiliary storage of fasteners, reducing the excessive stacking of fasteners after they are directly put into the material frame 1, which would cause the fasteners to be tightly attached with small gaps, resulting in a slower process of hot air penetrating the gaps and uneven heating of the fastener surface. This improves the heat treatment efficiency of the fasteners.

[0034] Figure 2-6A rubber ring 210 is fixed to the side of the placement disk 22 near the shaft seat 21. The rubber ring 210 is circularly sleeved on the shaft seat 21. By setting the rubber ring 210, the placement disk 22 and the shaft seat 21 can be separated, reducing the collision and wear between the shaft seat 21 and the placement disk 22. At the same time, it can also separate two adjacent placement disks 22, reducing the contact wear between the two placement disks 22. Multiple protrusions 24 are fixed to the inner wall of the placement disk 22. The multiple protrusions 24 are arranged at equal intervals. By setting the protrusions 24, the protrusions 24 can support the fasteners, so that there is a certain gap between the fasteners and the inner wall of the placement disk 22, improving the flow of hot air between the fasteners and the inner wall of the placement disk 22.

[0035] Figure 2-6 The placement tray 22 shown has multiple rectangular holes 25 on one side. Each rectangular hole 25 has a partition 26 slidably connected to its inner wall. By setting the partitions 26, personnel can insert the partitions 26 into the placement tray 22 through the rectangular holes 25 respectively. The partitions 26 divide the storage area inside the placement tray 22 into multiple small areas, and then store the fasteners in different areas, further improving the classification and separation of fasteners. The inner wall of the placement tray 22 is fixed with a handle 23. The inner side of the handle 23 has multiple anti-slip protrusions. The handle 23 provides a point of leverage for personnel to manually move the placement tray 22, allowing personnel to move the placement tray 22 by manually moving the handle 23, improving the convenience and stability of manually moving the placement tray 22.

[0036] Figure 2-6 The surface of the shaft seat 21 shown is fitted with a cover plate 27. A threaded ring 28 is threaded onto the end of the shaft seat 21 away from the material frame 1. The cover plate 27 is adapted to the size and shape of the placement tray 22. By setting the cover plate 27, after multiple placement trays 22 are sequentially fitted onto the shaft seat 21, the cover plate 27 is manually fitted onto the shaft seat 21, making the cover plate 27 fit against the surface of the uppermost placement tray 22. At this time, the threaded ring 28 is manually rotated, causing the threaded ring 28 to move up and down along the surface of the shaft seat 21, thus opening the threaded hole... During movement, the ring 28 fixes the position of the cover plate 27 by pressing it, so that the cover plate 27 covers the placement tray 22 and covers and seals the opening of the placement tray 22, reducing the possibility of fasteners falling out of the uppermost placement tray 22 during transportation. Multiple auxiliary blocks 29 are fixed to the surface of the screw hole ring 28. The surface of the auxiliary blocks 29 is rectangular. By setting the auxiliary blocks 29, the hands can be intercepted, reducing the possibility of slippage when the personnel manually rotate the screw hole ring 28.

[0037] Working principle: First, fasteners are evenly placed on the placement tray 22. Then, the placement tray 22 is manually moved, causing the fasteners to move. When the placement tray 22 moves to fit onto the shaft seat 21, it is placed inside the material frame 1. Then, multiple placement trays 22 are loaded with fasteners and sequentially fitted onto the shaft seat 21, stacking the trays 22 on the shaft seat 21. Then, the cover plate 27 is manually fitted onto the shaft seat 21, making the cover plate 27 fit against the surface of the uppermost placement tray 22. Then, the screw hole ring 28 is manually rotated, causing it to move up and down along the surface of the shaft seat 21. During the movement, the screw hole ring 28 presses against the cover plate 27 to fix its position, covering and sealing the opening of the placement tray 22. This allows the stored fasteners to be layered and stored inside the material frame 1 under the action of multiple placement trays 22, avoiding excessive stacking or tight contact between fasteners, thus completing the auxiliary storage of fasteners.
