[0002] A sample heat treatment apparatus refers to a specialized piece of equipment or system used to perform heat treatment processes on specific samples. Its core function is to modify the microstructure and properties of the sample according to preset heat treatment parameters to meet different research, testing, or production needs.

[0003] Existing sample heat treatment equipment lacks a cooling structure. When it is necessary to cool the sample workpiece, it is necessary to move the sample workpiece to an additional cooling device, which causes many inconveniences. Utility Model Content

[0004] The purpose of this invention is to provide a sample heat treatment device that facilitates cooling, thereby solving the problem of inconvenient cooling of sample workpieces in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

One of the vertical plates has a slot on its side wall, and the slot is slidably connected to the heating coil.

[0007] Preferably, a box is fixedly connected to the lower end of the base, and two pipes are provided between the inside of the box and the inside of the cavity. The pipes are fixedly connected to the upper end of the box and the lower end of the base, respectively.

[0008] Preferably, an air pump is fixedly connected to the lower end of the box, the output end of the air pump is connected to the inside of the box, and two coolers are fixedly connected to the lower end of the box, with the cooling end of the cooler located inside the box.

[0009] Preferably, a screw is rotatably connected inside the groove, the screw is threadedly connected to the movable frame, a motor is fixedly connected to the side wall of the base, and the output end of the motor is fixedly connected to the end of the screw through a coupling.

[0010] Preferably, two crossbars are fixedly connected to the side wall of the clamping plate, and the crossbars are slidably connected to the side wall of the rotating seat.

[0012] Compared with the prior art, the advantages of this utility model are:

[0013] 1. By driving the screw to rotate by the motor, the movable frame and heating coil are slowly laterally slid, allowing the heating coil to move around the workpiece and perform comprehensive heat treatment on the workpiece. This method can ensure that all parts of the workpiece are heated evenly, avoiding problems such as uneven microstructure and inconsistent performance caused by local overheating or undercooling, thereby improving the quality and performance stability of the workpiece after heat treatment.

[0014] 2. The air pump delivers external airflow to the chamber and cools it through the cooler. The cold airflow then quickly enters the chamber through the pipe and is ejected from the holes, directly acting on the surface of the workpiece. The rotation of the workpiece ensures that the cold airflow comes into full contact with the workpiece surface, accelerating the heat exchange rate. This allows the workpiece to be cooled to the required temperature in a shorter time, greatly improving cooling efficiency and shortening the heat treatment cycle. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-5A sample heat treatment device for easy cooling includes a base 001, with a chamber 101 inside the base 001. Multiple holes 102 are provided at the upper end of the base 001, and a filter screen 107 is fixedly connected inside each hole 102. A groove 108 is provided on the side wall of the base 001, and a movable frame 111 is slidably connected inside the groove 108. A heating coil 112 is fixedly connected to the side wall of the movable frame 111. Two vertical plates 002 are fixedly mounted on the upper end of the base 001, and a rotating seat 201 is slidably connected through the side wall of the vertical plates 002. There is a clamping plate 202, and an electric actuator 203 is fixedly connected to the side wall of the rotating base 201. The output end of the electric actuator 203 is fixedly connected to the side wall of the clamping plate 202. One of the vertical plates 002 has a slot 208 on its side wall, which is slidably connected to the heating coil 112. The clamping plate 202 is made of high-temperature resistant material, and external impurities are blocked by the filter screen 107 to prevent them from falling into the hole 102. The operator moves the cylindrical sample workpiece between the two clamping plates 202 using external hoisting equipment, and then operates the two electric actuators 203. The output end of 203 pushes the two clamping plates 202 to slide relative to each other, so that the clamping plates 202 clamp and fix the workpiece from both ends. Then, the movable frame 111 drives the heating coil 112 to slide, and the heating coil 112 slides out from inside the slot 208. The heating coil 112 moves to the outside of the workpiece, and then the operator operates the heating coil 112 to heat the workpiece. Then, the movable frame 111 drives the heating coil 112 to slowly slide laterally, thereby performing a comprehensive heat treatment on the workpiece. After the workpiece is heat treated, the heating coil 112 stops operating. The frame 111 drives the heating coil 112 to slide towards the slot 208, and slides the heating coil 112 into the slot 208 for storage and concealment. Then, cold air flows inside the chamber 101 and is sprayed out through multiple holes 102 onto the surface of the heat-treated workpiece to cool it down. At the same time, one of the rotating seats 201 drives one of the clamping plates 202 to rotate slowly, causing the workpiece to rotate slowly. Meanwhile, another clamping plate 202 drives another rotating seat 201 to rotate, so that the cold air can cool the workpiece comprehensively, thus facilitating the cooling of the workpiece.

[0023] The lower end of the base 001 is fixedly connected to the box 103. Two pipes 104 are provided between the inside of the box 103 and the inside of the chamber 101. The pipes 104 are fixedly connected to the upper end of the box 103 and the lower end of the base 001 respectively. Cold air flows inside the box 103 and flows into the chamber 101 through the two pipes 104.

[0024] An air pump 105 is fixedly connected to the lower end of the housing 103. The output end of the air pump 105 is connected to the inside of the housing 103. Two coolers 106 are fixedly connected to the lower end of the housing 103. The cooling end of the cooler 106 is located inside the housing 103. A filter plate is fixedly connected inside the input end of the air pump 105. The air pump 105 delivers external airflow to the inside of the housing 103, and then the airflow is cooled to a lower temperature by the two coolers 106.

[0025] A screw 109 is rotatably connected inside the groove 108. The screw 109 is threadedly connected to the movable frame 111. A motor 110 is fixedly connected to the side wall of the base 001. The output end of the motor 110 is fixedly connected to the end of the screw 109 through a coupling. The output end of the motor 110 drives the screw 109 to rotate. Then, through the threaded engagement between the screw 109 and the movable frame 111, the movable frame 111 moves laterally.

[0026] Two crossbars 204 are fixedly connected to the side wall of the clamping plate 202. The crossbars 204 are slidably connected to the side wall of the rotating seat 201. The rotating seat 201 drives the clamping plate 202 to rotate through the crossbars 204.

[0027] A gear 206 is rotatably connected inside the side wall of one of the vertical plates 002. A plurality of toothed grooves 205 are provided on the side wall of one of the rotating seats 201. The toothed grooves 205 cooperate with the gear 206. A drive motor 207 is fixedly connected to the side wall of one of the vertical plates 002. The output end of the drive motor 207 is fixedly connected to the side wall of the gear 206. The gear 206 is a spur gear. The toothed grooves 205 are grooves that match the tooth blocks on the side wall of the spur gear. The output end of the drive motor 207 drives the gear 206 to rotate. Through the cooperation between the gear 206 and the toothed grooves 205, one of the rotating seats 201 rotates.

[0028] In this utility model, the operator moves the cylindrical sample workpiece between the two clamping plates 202 using an external hoisting device. Then, the operator operates the two electric actuators 203. The output ends of the two electric actuators 203 push the two clamping plates 202 to slide relative to each other. At the same time, the clamping plates 202 drive the crossbar 204 to slide, so that the clamping plates 202 clamp and fix the workpiece from both ends.

[0029] After the workpiece is clamped and fixed, the screw 109 is driven to rotate by the output end of the motor 110. Then, through the threaded engagement between the screw 109 and the movable frame 111, the movable frame 111 moves laterally. The movable frame 111 drives the heating coil 112 to slide, and the heating coil 112 slides out from inside the slot 208. The heating coil 112 moves to the outside of the workpiece, and then the operator operates the heating coil 112 to heat the workpiece. Then, the movable frame 111 drives the heating coil 112 to slide slowly laterally, thereby performing a comprehensive heat treatment on the workpiece. After the workpiece is heat treated, the heating coil 112 stops operating, and the movable frame 111 drives the heating coil 112 to slide towards the slot 208, sliding the heating coil 112 into the slot 208 for storage and concealment.

[0030] A filter plate is fixedly connected inside the input end of the air pump 105. The air pump 105 delivers external airflow to the inside of the housing 103, and then the airflow is cooled to a lower temperature by two coolers 106. The cold airflow flows into the chamber 101 through two pipes 104. The cold airflow is sprayed onto the surface of the heat-treated workpiece through multiple holes 102 to cool the workpiece. At the same time, the output end of the drive motor 207 drives the gear 206 to rotate. Through the cooperation between the gear 206 and the tooth groove 205, one of the rotating seats 201 rotates. One of the rotating seats 201 drives one of the clamping plates 202 to rotate slowly through the crossbar 204, so that the workpiece rotates slowly. At the same time, the other clamping plate 202 drives the other rotating seat 201 to rotate through the crossbar 204, so that the cold airflow cools the workpiece comprehensively, thereby facilitating the cooling of the workpiece.
