Description

Technical Field

[0001] This utility model relates to the field of shrapnel production and processing technology, specifically a heat treatment device for shrapnel production and processing. Background Technology

[0002] The characteristic of sheet springs is that they are easy to bend in only one direction—the plane of minimum stiffness—while having large tensile and bending stiffness in the other direction. Therefore, sheet springs are very suitable for use as sensitive elements, elastic supports, positioning devices, flexible connections, etc. in detection instruments or automatic devices. The production and processing of sheet springs usually includes key steps such as material preparation, stamping, heat treatment, surface treatment, testing and packaging.

[0003] In the heat treatment of shrapnel, heat treatment equipment is usually used. However, when heat treating a large number of shrapnel, the current heat treatment equipment requires the staff to place the material trays from the inside to the outside in the heat treatment furnace. After the heat treatment is completed, when taking out the innermost material tray, the staff needs to put their entire arm into the heat treatment furnace and then take out the material one by one. This not only increases the workload of the staff, but also reduces the efficiency of subsequent heat treatment. Utility Model Content

[0004] The purpose of this invention is to provide a heat treatment device for the production and processing of shrapnel, so as to solve the problems existing in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a heat treatment apparatus for the production and processing of shrapnel, comprising a heat treatment apparatus body, and further comprising:

[0006] A heat treatment furnace is fixedly connected inside the body of the heat treatment device. A sliding plate is fixedly connected to the bottom of the inner wall of the heat treatment furnace, and a trapezoidal slider is slidably connected to the top of the sliding plate.

[0007] A material tray is provided at one end of the trapezoidal slider, and a movable plate for easy material discharge is movably connected to the bottom of one end of the material tray. The trapezoidal slider has a disassembly structure inside.

[0008] Preferably, the disassembly structure includes a T-shaped block movably connected inside the trapezoidal slider, with one end of the T-shaped block fixedly connected to one end of the material tray. Both ends of the top of the trapezoidal slider are fixedly connected to a fixing rod, and a limiting plate is rotatably connected to the surface of the fixing rod, with the bottom of the limiting plate abutting against the top of the trapezoidal slider.

[0009] Preferably, sliders are fixedly connected to both sides of the movable plate, and grooves are opened on both sides inside one end of the material tray, with the surface of the sliders slidingly connected to the inside of the grooves.

[0010] Preferably, a fixing plate is fixedly connected to the top of one end of the movable plate, a fixing bolt is slidably inserted through the top of the fixing plate, and the bottom of the fixing bolt is used in conjunction with the top of one end of the material tray.

[0011] Preferably, a collection box is provided on one side of the top of the heat treatment device body, and the collection box is located below the moving plate.

[0012] Preferably, the material tray is arc-shaped, and the length of the material tray is less than the length of the slide plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] In this invention, the sliding plate allows the material tray to be pushed into the heat treatment furnace when a large number of spring pieces need to be heat-treated. The sliding connection between the sliding plate and the trapezoidal slider enables the material tray to be pulled out from the outermost side of the furnace after heat treatment. This allows the worker to remove the heat-treated spring pieces without having to put their entire arm into the furnace, greatly improving work efficiency. Furthermore, after prolonged use, the material tray can be replaced by disassembling the structure to facilitate better heat treatment of the spring pieces in the future. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-6 As shown, a heat treatment device for producing and processing shrapnel includes a heat treatment device body 1. A heat treatment furnace 2 is fixedly connected inside the heat treatment device body 1. A sliding plate 3 is fixedly connected to the bottom of the inner wall of the heat treatment furnace 2. A trapezoidal slider 4 is slidably connected to the top of the sliding plate 3. A material tray 6 is provided at one end of the trapezoidal slider 4. A movable plate 7 for facilitating material discharge is movably connected to the bottom of one end of the material tray 6. A collection box 12 is provided on one side of the top of the heat treatment device body 1, and the collection box 12 is located below the movable plate 7. With the setting of the collection box 12, after the shrapnel processing is completed, the workers can use the collection box 12 to collect the shrapnel, thus greatly saving time and improving work efficiency. The material tray 6 is arc-shaped, and its length is less than that of the slide plate 3. The arc shape of the material tray 6 greatly increases its load-bearing capacity for the spring sheet, and also facilitates the subsequent unloading of the spring sheet after heat treatment, thus improving the work efficiency of the staff. The movable plate 7 is fixedly connected to both sides of the sliding plate 7. The material tray 6 has two sliding grooves 10 on both sides of its inner end. The surface of the sliding plate 9 is slidably connected to the inside of the sliding groove 10. Through the setting of the sliding plate 9 and the sliding groove 10, the movable plate 7 can slide at one end of the material tray 6 and can also provide auxiliary support for the movable plate 7, which facilitates the subsequent work of the staff. The trapezoidal sliding plate 4 is equipped with a disassembly structure 5 inside.

[0024] The disassembly structure 5 includes a T-shaped block 51 movably connected inside the trapezoidal slider 4, with one end of the T-shaped block 51 fixedly connected to one end of the material tray 6. Fixed rods 52 are fixedly connected to both ends of the top of the trapezoidal slider 4. Limiting plates 53 are rotatably connected to the surface of the fixing rods 52, and the bottom of the limiting plates 53 is in contact with the top of the trapezoidal slider 4. With the disassembly structure 5, when the material tray 6 needs to be replaced after prolonged use, the operator can rotate the limiting plates 53 in opposite directions simultaneously through the rotatable connection between the limiting plates 53 and the fixing rods 52, thereby removing the limiting plates 53 from the T-shaped block 51. This allows the T-shaped block 51 to slide upwards from inside the trapezoidal slider 4, and the operator can then remove the T-shaped block 51 and the material tray 6 from the heat treatment furnace 2, thus enabling the replacement of the material tray 6 after prolonged use.

[0025] A fixed plate 11 is fixedly connected to the top of one end of the movable plate 7. A fixing bolt 8 slides through the top of the fixed plate 11, and the bottom of the fixing bolt 8 cooperates with the top of one end of the material tray 6. With the setting of the fixing bolt 8, before the spring sheet is heat treated, the operator can slide the movable plate 7 to a specific position and tighten the fixing bolt 8, so that the movable plate 7 is more stably fixed to the bottom of the material tray 6.

[0026] It is worth noting that the technical features such as the heat treatment device body 1 and the heat treatment furnace 2 proposed in this technical solution should be regarded as prior art. The specific structure, working principle, and possible control methods and spatial arrangement of these technical features can be selected using conventional methods in this field. This technical solution will not elaborate further.

[0027] Working principle: When a large number of spring pieces need to be heat-treated, the material tray 6 is first pulled out of the heat treatment furnace 2 through the sliding connection between the slide plate 3 and the trapezoidal slider 4. Then, the spring pieces are evenly placed in the material tray 6, and then the material tray 6 is pushed into the heat treatment furnace 2 for vacuum heat treatment. After the heat treatment is completed, the heat treatment furnace 2 is opened, and the material tray 6 is pulled out until most of its area is outside the heat treatment furnace 2. Then, the fixing bolt 8 is removed from the moving plate 7. Then, through the sliding connection between the slider 9 and the slide groove 10, the moving plate 7 can be moved outward, so that the bottom of the material tray 6 is empty. The gap is created, forming a material discharge port. Then, the workers can push the spring pieces at both ends of the material tray 6 to the material discharge port, so that all the spring pieces fall into the collection box 12 below. This greatly saves the workers' workload and improves work efficiency. However, after a long period of use, the material tray 6 inside may deform, which may affect the heat treatment effect of the spring pieces. The workers first slide the trapezoidal slider 4 to the outermost side, and then rotate the limiting plates 53 at both ends in opposite directions at the same time. This cancels the limiting plates 53 from limiting the T-block 51, so that the workers can take the material tray 6 out of the heat treatment furnace 2 and then replace it with a new material tray 6.
