Description

Technical Field

[0001] This utility model relates to the field of vacuum quenching equipment technology, and in particular to a high-efficiency heating vacuum quenching equipment. Background Technology

[0002] Existing mold vacuum quenching equipment cannot fix circular molds during use. Subsequent drying and cleaning require transfer to other equipment, which is slow and ineffective, thus affecting the quenching quality of the mold. In addition, existing mold vacuum quenching equipment requires manual handling to move to a suitable location when needed, which is labor-intensive.

[0003] In the prior art, patent number (CN202122318248.0) mentions a high-efficiency heating mold vacuum quenching equipment, including a box body. A support plate is fixedly installed inside the box body. An adjustment structure is set below the support plate. The adjustment structure includes a first drive motor, a bidirectional screw, and a moving plate. Shock-absorbing components are set around the bottom of the moving plate. Universal wheels are set at the bottom of the shock-absorbing components. Two electric heating tubes are set at the top of the box body. A cleaning component is set on the box body. A lifting cylinder is set at the top of the support plate. The box body is set at the top of the lifting cylinder. A worktable is set at the top of the box body. Quenching devices are fixedly installed on both sides of the box body. It can fix molds with circular structures of different sizes. At the same time, the mold can be cleaned without transferring equipment in subsequent processing. The universal wheels can be stored and supported, making it convenient for users.

[0004] The addition of a cleaning component to the existing technology effectively solves the problem that subsequent drying and cleaning require transfer of equipment, resulting in slow cleaning speed and poor effect, which in turn affects the quenching quality of the mold. However, the existing heating method is not reasonable enough, with uneven heat distribution, resulting in long workpiece heating time, high energy consumption, and also affecting the consistency of workpiece quality after quenching.

[0020] This utility model provides a high-efficiency vacuum quenching device, including a heating chamber 101 and a matrix-type high-efficiency vacuum quenching assembly. The matrix-type high-efficiency vacuum quenching assembly includes a heat-collecting rod 110, several heaters 111, a support rod 107, a mounting platform 108, a clamping plate 109, a protective shell 102, an opening slot 103, a heating door 104, a sealing door 105, a suction pipe 106, a groove 112, a top plate 113, and a locking block 114. This solution solves the problems of unreasonable heating methods and uneven heat distribution in existing equipment, resulting in long heating times, high energy consumption, and inconsistent quality of quenched workpieces. It is understood that the aforementioned solution allows for opening the sealing door 105 and the heating chamber during use. Door 104 is used to place the parts to be quenched onto the clamping plate 109 through the opening slot 103. The clamping plate 109 can be replaced according to the shape and size of the parts. Its internal clamping structure firmly fixes the parts to prevent displacement during subsequent processing. After clamping, the heating door 104 and the sealing door 105 are closed to form a closed space in the heating chamber 101. Then, the other end of the exhaust pipe 106 is tightly connected to an external exhaust device (such as a vacuum pump) through a sealed interface to ensure airtightness at the connection. The external exhaust device is started, and the exhaust pipe 106 begins to work. One end of it passes through the protective shell 102 and the heating chamber 101, continuously extracting air from inside the heating chamber 101. As the evacuation process proceeds, the air pressure inside the heating chamber 101 gradually decreases until the required vacuum level is reached. This vacuum level parameter can be preset through the equipment control system. When the built-in vacuum sensor detects that the vacuum level inside the chamber has reached the set value, the control system automatically sends a signal to stop the operation of the external evacuation equipment. Heating is then initiated by the heater 111 in a vacuum environment, effectively preventing oxidation of the parts to be quenched during heating. This also lays the foundation for subsequent efficient and uniform heating. Because the heaters 111 are arranged in a matrix above the clamping plate 109, they can uniformly heat the parts to be quenched from multiple directions. Compared to traditional heating methods, this significantly improves the uniformity of heat distribution and reduces... With reduced localized temperature differences, the heat-collecting rod 110 plays an auxiliary role in temperature control during the heating process. Made of a highly thermally conductive material, the heat-collecting rod 110 can quickly absorb the heat generated by the heater 111 and evenly distribute it to the surrounding space. Simultaneously, the heat-collecting rod 110 incorporates a temperature sensor to monitor its surface temperature in real time and feeds the data back to the equipment control system. When the temperature deviates from the preset quenching temperature range, the control system automatically adjusts the power of the heater 111: if the temperature is too high, the power of the heater 111 is reduced; if the temperature is too low, the power of the heater 111 is increased. This achieves constant temperature control for the quenching of the parts on the clamping plate 109, ensuring the stability of the quenching process and the consistency of the parts' quality.

[0021] In this specific embodiment, the heat-collecting rod 110 is fixedly connected to the heating box 101 and located inside the lower part of the heating box 101. A plurality of heaters 111 are detachably connected to the heating box 101 and located inside the upper part of the heating box 101. The support rod 107 is detachably connected to the heating box 101 and located at the lower center inside the heating box 101. The mounting platform 108 is detachably connected to the support rod 107 and located above the support rod 107. The mounting platform 108 is disposed on one side of the heat-collecting rod 110. The clamping plate 109 is detachably connected to the mounting platform 108 and located above the center of the mounting platform 108. The clamping plate 109 is also disposed below the heaters 111.

[0022] The protective shell 102 is detachably connected to the heating box 101 and is located on the outer surface of the heating box 101.

[0023] Secondly, the opening slot 103 is fixedly connected to the heating box 101 and the protective shell 102, and is located on the inner side of the heating box 101 and the protective shell 102. The opening slot 103 is perpendicular to the heat collecting rod 110. The heating door 104 is rotatably connected to the heating box 101 and is located inside the heating box 101. The heating door 104 is located on the inner side of the opening slot 103. The sealing door 105 is rotatably connected to the protective shell 102 and is located inside the protective shell 102. The sealing door 105 is located on the inner side of the opening slot 103 away from the heating door 104.

[0024] Meanwhile, one end of the exhaust pipe 106 passes through the protective shell 102 and the heating box 101 and is located inside the lower part of the heating box 101, the other end of the exhaust pipe 106 is located below the protective shell 102, and one end of the exhaust pipe 106 is located on one side of the support rod 107.

[0025] In addition, the groove 112 is fixedly connected to the heating box 101 and is located inside the upper part of the heating box 101. The groove 112 is located above the heater 111. The top plate 113 is located above the heating box 101. The locking block 114 is fixedly connected to the top plate 113 and is located below the top plate 113. The locking block 114 is also detachably connected to the heating box 101 and is located inside the upper part of the heating box 101. The locking block 114 is also located inside the groove 112.

[0026] When using this utility model, open the sealing door 105 and the heating door 104, and place the parts to be quenched onto the clamping plate 109 through the opening slot 103. The clamping plate 109 can be replaced according to the shape and size of the parts. Its internal clamping structure securely fixes the parts, preventing displacement during subsequent processing. After clamping, close the heating door 104 and the sealing door 105, creating a closed space in the heating chamber 101. Then, connect the other end of the extraction pipe 106 to an external extraction device (such as a vacuum pump) through a seal. The interfaces are tightly connected to ensure airtightness at the connection point. When the external vacuum equipment is activated, the vacuum pipe 106 begins operation, with one end passing through the protective shell 102 and the heating chamber 101, continuously extracting air from inside the heating chamber 101. As the vacuuming process proceeds, the air pressure inside the heating chamber 101 gradually decreases until the required vacuum level is reached. This vacuum level parameter can be preset through the equipment control system. When the built-in vacuum sensor detects that the vacuum level inside the chamber has reached the set value, the control system automatically sends a signal to stop the operation of the external vacuum equipment. Heating the parts by turning on the heater 111 in an empty environment can effectively avoid oxidation and other problems during the heating process, and lay the foundation for efficient and uniform heating in the future. Since the heaters 111 are arranged in a matrix above the clamping plate 109, they can heat the parts to be quenched uniformly from multiple directions. Compared with traditional heating methods, this significantly improves the uniformity of heat distribution and reduces local temperature differences. During the heating process, the heat collecting rod 110 plays an auxiliary role in temperature control. The heat collecting rod 110 is made of a high thermal conductivity material and can quickly absorb heat. The heater 111 generates heat and distributes it evenly to the surrounding space. At the same time, the heat collection rod 110 has a built-in temperature sensor that monitors its surface temperature in real time and feeds the data back to the equipment control system. When the temperature deviates from the preset quenching temperature range, the control system automatically adjusts the power of the heater 111: if the temperature is too high, the power of the heater 111 is reduced; if the temperature is too low, the power of the heater 111 is increased. This achieves constant temperature control for the quenching of the parts on the clamping plate 109, ensuring the stability of the quenching process and the consistency of the part quality.
