Description

Technical Field

[0001] This utility model belongs to the field of lead screw processing technology, and in particular relates to a heat treatment device for lead screw processing. Background Technology

[0002] In the heat treatment of lead screws, box-type resistance furnaces are commonly used heat treatment devices. Based on the principle of resistance heating, they convert electrical energy into heat energy through heating elements inside the furnace to perform processes such as annealing, normalizing, quenching, and tempering on the lead screws. The furnace body is welded with double-layer steel plates and filled with refractory materials. Equipped with a PID temperature control system, it can control the temperature between 600-1300℃, meeting the heat treatment requirements of lead screws of most materials. This device is highly versatile, easy to operate, and suitable for single-piece or small-batch lead screw production, playing an important role in the heat treatment of lead screws.

[0003] The existing technology has the following problems: When using existing box-type resistance furnaces, the lead screw is usually placed directly inside the furnace, which leads to contact between adjacent lead screws and large-area contact with the support or inner wall of the furnace. This can easily cause uneven heat conduction during heat treatment, affecting the uniformity and consistency of the lead screw heat treatment. At the same time, the support cannot flexibly adapt to lead screws of different lengths, the adjustment is cumbersome and the versatility is poor. When manually loading and unloading the lead screw, the fixed position of the support makes operation inconvenient and reduces work efficiency. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model provides a heat treatment device for lead screw processing. It has the advantages of flexibly adjusting the placement spacing and avoiding uneven heat conduction caused by the contact and stacking of lead screws. To a certain extent, it improves or solves the problem that when using existing box-type resistance furnaces, the lead screw is usually placed directly inside the furnace, resulting in contact between adjacent lead screws and large-area contact with the support or inner wall of the machine box, which easily causes uneven heat conduction during heat treatment and affects the uniformity of lead screw heat treatment. At the same time, the support cannot flexibly adapt to lead screws of different lengths, the adjustment is cumbersome and the versatility is poor. When manually loading and unloading lead screws, the fixed position of the support makes operation inconvenient and reduces work efficiency.

[0005] This utility model is implemented as follows: a heat treatment device for ball screw processing includes a chassis and a door. The door is located on the front side of the chassis and is rotatably connected to the chassis. A movable placement device is provided inside the chassis. The movable placement device includes a moving frame, an adjustment component, and a placement component.

[0006] The movable frame, as a preferred embodiment of this invention, is disposed inside the chassis and is movably connected to the chassis. Several adjustment components are evenly distributed on the left side inside the movable frame. Several placement components are respectively disposed on the right sides of the front and rear ends of the adjustment components. The movable placement device is used to place the lead screw. The movable frame can be pulled out and pushed in from inside the chassis, facilitating the placement and removal of the lead screw. The adjustment components can adjust the placement components according to the length of the lead screw to achieve a suitable placement spacing. The placement components ensure that the lead screw does not stack or contact each other during heat treatment inside the chassis, while also avoiding large-area contact with the frame, ensuring uniform heat contact during heat treatment and improving the uniformity and consistency of the lead screw's heat treatment quality.

[0007] The preferred embodiment of this utility model includes a sliding limiting groove, a frame, and slide rails. There are two sliding limiting grooves, each located at the upper and lower ends of the left side of the casing. The frame is disposed inside the casing and slidably connected to it. There are two slide rails, each fixedly connected to the upper and lower ends of the left side of the frame. The left ends of the two slide rails extend into the two sliding limiting grooves and are slidably connected to the casing. By configuring the movable frame and utilizing the precise fit between the sliding limiting grooves and slide rails, the frame can be smoothly pulled along the inside of the casing. This not only facilitates quick loading and unloading of the lead screw by the operator but also ensures the stability of the movable frame during movement and heat treatment through the frame structure.

[0008] The preferred adjustment component of this utility model includes a screw, a support limiting rod, a support block, and a knob. The screw is located inside the frame on the left side, with its rear end rotatably connected to the rear end of the frame and its front end extending out of the frame and rotatably connected to the frame. There are two support limiting rods, which are respectively located on the upper and lower sides of the screw. The front and rear ends of the two support limiting rods are respectively fixedly connected to the front and rear end surfaces of the frame. There are two support blocks, which are respectively sleeved on the front and rear end surfaces of the two support limiting rods and the screw. The support blocks are threadedly connected to the screw and slidably connected to the two support limiting rods. The knob is fixedly connected to the front end of the screw. By setting the adjustment component, the operator can drive the screw to rotate by rotating the knob in both directions, causing the two support blocks that are threadedly engaged with it to move back and forth along the support limiting rod, thereby flexibly adjusting the spacing of the placement components to adapt to the placement requirements of screws of different lengths, significantly improving the versatility and ease of adjustment of the device.

[0009] The preferred placement component of this utility model includes a placement rod and partition blocks. The placement rod is fixedly connected to the right side of the support block. The partition blocks are numerous and uniformly fixedly connected to the upper surface of the placement rod. By setting the placement component, the evenly distributed partition blocks on the placement rod can separate and support the lead screw in different sections, avoiding stacking and contact between the lead screws. At the same time, it reduces the large-area contact between the lead screw and the frame, ensuring that heat is evenly conducted to the surface of the lead screw during heat treatment, and effectively improving the consistency and stability of the heat treatment quality of the lead screw.

[0010] As a preferred embodiment of this utility model, a pull handle is provided on the lower front side of the frame. The pull handle is fixedly connected to the frame. By providing a pull handle on the lower front side of the frame, a convenient point of force is provided for the operator, which can easily push and pull the frame to slide along the chassis, significantly reducing the difficulty of moving the frame and improving the efficiency and user experience of screw loading and unloading.

[0011] The movable placement device, as a preferred embodiment of this utility model, is made of high-temperature resistant material. By using high-temperature resistant material, such as stainless steel or high-temperature alloy, the movable placement device can effectively resist the high-temperature environment inside the chassis, avoid deformation, oxidation or thermal damage caused by high temperature, and ensure that the movable placement device maintains structural stability and functional reliability during long-term high-frequency heat treatment operations. At the same time, due to the high strength characteristics of the material, its support strength is high and it is not easy to deform.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model, through the coordinated use of a chassis, door, movable placement device, moving frame, sliding limit groove, frame, slide rail, adjusting component, screw, support limit rod, support block, knob, placement component, placement rod, partition block, and pull handle, improves or solves to a certain extent the problem of uneven heat conduction during heat treatment caused by the direct placement of the lead screw inside the furnace in existing box-type resistance furnaces, resulting in contact between adjacent lead screws and large-area contact with the support or inner wall of the chassis, affecting the uniformity and consistency of the lead screw heat treatment. At the same time, the support cannot flexibly adapt to lead screws of different lengths, the adjustment is cumbersome and the versatility is poor. When manually loading and unloading the lead screw, the fixed position of the support makes operation inconvenient and reduces work efficiency. Attached Figure Description

[0015] To further understand the invention content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0016] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0017] like Figures 1 to 4 As shown in the figure, the heat treatment device for ball screw processing provided in this embodiment of the present invention includes a housing 1 and a door 2. The door 2 is located on the front side of the housing 1 and is rotatably connected to the housing 1. A movable placement device 3 is provided inside the housing 1. The movable placement device 3 includes a moving frame 31, an adjustment component 32 and a placement component 33.

[0018] refer to Figure 1 and Figure 2 The movable frame 31 is located inside the chassis 1 and is movably connected to the chassis 1. There are several adjustment components 32, which are evenly arranged on the left side inside the movable frame 31. There are several placement components 33, which are respectively located on the right side of the front and rear ends of the several adjustment components 32.

[0019] The above solution is adopted: by setting up a movable placement device 3, the lead screw is placed. Its movable frame 31 can be pulled out and pushed in from inside the machine box 1, which facilitates the placement and removal of the lead screw. Its adjustment component 32 can adjust the placement component 33 according to the length of the lead screw to achieve a suitable placement spacing. Its placement component 33 ensures that the lead screw does not stack or contact each other when it is placed inside the machine box 1 for heat treatment, and avoids large-area contact with the frame 312, ensuring uniform heat contact during the heat treatment process and improving the uniformity and consistency of the heat treatment quality of the lead screw.

[0020] refer to Figure 1 , Figure 2 and Figure 3The movable frame 31 includes a sliding limiting groove 311, a frame 312, and a slide rail 313. There are two sliding limiting grooves 311, which are respectively opened at the upper and lower ends of the left side of the chassis 1. The frame 312 is set inside the chassis 1 and is slidably connected to the chassis 1. There are two slide rails 313, which are respectively fixedly connected to the upper and lower ends of the left side of the frame 312. The left ends of the two slide rails 313 extend into the two sliding limiting grooves 311 and are slidably connected to the chassis 1.

[0021] The above solution is adopted: by setting up a movable frame 31, the frame 312 can be smoothly pulled out along the inside of the chassis 1 by using the precise cooperation between the sliding limit groove 311 and the slide rail 313. This not only makes it easy for operators to quickly load and unload the lead screw, but also ensures the stability of the movable frame 31 during movement and heat treatment through the structure of the frame 312.

[0022] refer to Figure 2 , Figure 3 and Figure 4 The adjustment assembly 32 includes a screw 321, a support limiting rod 322, a support block 323, and a knob 324. The screw 321 is located inside the left side of the frame 312, and its rear end is rotatably connected to the rear end of the frame 312. Its front end extends out of the frame 312 and is rotatably connected to the frame 312. There are two support limiting rods 322, which are respectively located on the upper and lower sides of the screw 321. The front and rear ends of the two support limiting rods 322 are respectively fixedly connected to the front and rear end surfaces inside the frame 312. There are two support blocks 323, which are respectively sleeved on the front and rear end surfaces of the two support limiting rods 322 and the screw 321. The support blocks 323 are threadedly connected to the screw 321 and slidably connected to the two support limiting rods 322. The knob 324 is fixedly connected to the front end of the screw 321.

[0023] By adopting the above solution: by setting the adjustment component 32, the operator can drive the screw 321 to rotate by rotating the knob 324 in both directions, so that the two support blocks 323 that are threadedly engaged with it can move back and forth along the support limit rod 322, thereby flexibly adjusting the spacing of the placement component 33 to adapt to the placement requirements of screws of different lengths, significantly improving the versatility and ease of adjustment of the device.

[0024] refer to Figure 2 , Figure 3 and Figure 4 The placement component 33 includes a placement rod 331 and a partition block 332. The placement rod 331 is fixedly connected to the right side of the support block 323. The partition block 332 is a plurality of blocks, which are evenly fixedly connected to the upper surface of the placement rod 331.

[0025] The above solution is adopted: by setting up the placement component 33, the evenly distributed partition blocks 332 on the placement rod 331 can separate and support the lead screw in different sections, avoiding the lead screws from stacking and contacting each other, while reducing the large area contact between the lead screw and the frame 312, ensuring that heat is evenly conducted to the surface of the lead screw during the heat treatment process, and effectively improving the consistency and stability of the heat treatment quality of the lead screw.

[0026] refer to Figure 1 , Figure 2 and Figure 3 A pull handle 4 is provided on the lower front side of the frame 312, and the pull handle 4 is fixedly connected to the frame 312.

[0027] The above solution provides a convenient point of force application for the operator by setting a pull handle 4 on the lower front side of the frame 312, which can easily push and pull the frame 312 to slide along the chassis, significantly reducing the difficulty of moving the frame and improving the efficiency and user experience of screw loading and unloading.

[0028] refer to Figure 2 , Figure 3 and Figure 4 All movable placement devices 3 are made of high-temperature resistant materials.

[0029] The above solution is adopted: by using high-temperature resistant materials, such as stainless steel or high-temperature alloys, the movable placement device 3 can effectively resist the high-temperature environment inside the chassis 1, avoid deformation, oxidation or thermal damage of the device due to high temperature, and ensure that the movable placement device 3 maintains structural stability and functional reliability in long-term high-frequency heat treatment operations. At the same time, due to the high strength characteristics of the material, its support strength is high and it is not easy to deform.

[0030] The working principle of this utility model: In use, the operator first pulls the frame 312, which is slidably connected to the housing 1, out smoothly by sliding the limit groove 311 inside the housing 1 along the pull handle 4 on the lower front side of the frame 312. At this time, according to the specific length of the lead screw to be heat-treated, the knob 324 at the front end of the screw 321 in the adjusting assembly 32 is rotated to drive the screw 321 to rotate. Since the support block 323 is threadedly connected to the screw 321 and slidably connected to the support limit rods 322 on the upper and lower sides, the two support blocks 323 will slide back and forth along the support limit rods 322, thereby adjusting the placement assembly 3 fixed on the right side of the support block 323. The spacing of 3 is adjusted until a position suitable for the current lead screw length is reached. Then, the lead screws are placed one by one on the placement rod 331. The evenly distributed partition blocks 332 on the placement rod 331 are used to separate and support the lead screws in different sections, ensuring that the lead screws do not stack or contact each other, while reducing the large area of ​​contact between the lead screws and the frame 312. After confirming that all lead screws are properly placed, the frame 312 is pushed so that the slide rails 313 at the upper and lower ends of the left side of the frame 312 slide along the sliding limit groove 311, and the moving frame 31 is smoothly sent into the machine box 1. The box door 2 is closed and the heat treatment program of the box-type resistance furnace is started. After the heat treatment process is completed and the temperature is lowered, the movable frame 31 can be pulled out of the casing 1 again by using the pull handle 4, and the heat-treated lead screw can be easily removed, thus completing the entire operation process.

[0031] In summary, this heat treatment device for lead screw processing, through the coordinated use of a chassis 1, a door 2, a movable placement device 3, a moving frame 31, a sliding limit groove 311, a frame 312, a slide rail 313, an adjusting component 32, a screw 321, a support limit rod 322, a support block 323, a knob 324, a placement component 33, a placement rod 331, a partition block 332, and a pull handle 4, improves or solves to some extent the problem that in existing box-type resistance furnaces, the lead screw is usually placed directly inside the furnace, leading to contact between adjacent lead screws and large-area contact with the support or the inner wall of the chassis, which easily causes uneven heat conduction during heat treatment and affects the uniformity of lead screw heat treatment. At the same time, the support cannot flexibly adapt to lead screws of different lengths, the adjustment is cumbersome and the versatility is poor, and the fixed position of the support makes manual loading and unloading of lead screws inconvenient and reduces work efficiency.
