Description

Technical Field

[0001] The present invention relates to the field of casting heat treatment equipment, and more specifically, to a temperature-controlled heat treatment equipment for high-chromium castings. Background Art

[0002] The high-chromium cast iron internal gear ring is a gear component made of high-chromium cast iron material. It combines the excellent properties of high-chromium cast iron, such as high hardness, high strength, and excellent wear resistance, and is widely used in various mechanical equipment that requires high strength and wear resistance. The structure of high-chromium cast iron in the as-cast state often contains a certain amount of martensite, retained austenite, and coarse and continuously distributed carbides, and the grain size distribution is uneven, and the internal stress is also relatively large. These factors all reduce the mechanical properties of high-chromium cast iron and make it difficult to be directly used in the as-cast state. Through heat treatment, the matrix structure can be optimized and the wear resistance of high-chromium cast iron can be improved.

[0003] When processing the high-chromium cast iron internal gear ring in the prior art, an inductor on a quenching machine is usually used to heat-treat the internal gear ring. During use, the operator needs to use a fixture to clamp the internal gear ring and put it on the inductor, and through the alternating magnetic field generated by the inductor, the rapid heating of the internal gear ring is realized. However, the degree of automation of this operation process is relatively low, resulting in difficulty in improving the heat treatment efficiency, which has become a key factor restricting the production efficiency. In view of this, we propose a temperature-controlled heat treatment equipment for high-chromium castings. Summary of the Invention

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1. The internal gear ring is conveyed by multiple first electric rollers. The internal gear ring passes through the mounting frame and the baffle and moves onto the second electric roller. The internal gear ring is conveyed onto the support plate by the second electric roller. The internal gear ring enters the positioning groove through the guiding surface. The center of the internal gear ring and the center of the through hole are on the same vertical line. After heating, the quenching machine inductor moves upward out of the through hole. The chain conveyor drives the support groove at the end of the lifting plate to squeeze the bottom end of the second blanking plate. At this time, the second blanking plate slides along the inner wall of the chute. At the same time, the third sliding rod slides along the second support block. When the second blanking plate moves upward, it pushes the first blanking plate to rotate around the second rotating shaft. When the first blanking plate rotates, it drives the support plate to rotate downward around the first rotating shaft through the connecting shaft. The end of the support plate squeezes the clamping post until the support plate disengages from the clamping post. At this time, the support plate tilts, so that the internal gear ring can slide out of the support plate onto the first blanking plate, and the internal gear ring is conveyed onto the lifting plate by the second blanking plate. This design makes the whole processing process more automated, reduces manual intervention, improves production efficiency and accuracy, ensures the rapid and continuous movement of the internal gear ring on the production line, reduces waiting time, and improves the overall production efficiency.

[0019] 2. By rotating the adjusting screw rod to drive the connecting column to move, the connecting column drives the fixing rod to slide along the inner wall of the limiting plate. When the fixing rod moves, it drives the sliding sleeve to move. The sliding sleeve slides along the outer wall of the fixing rod. At this time, the positioning block drives the sliding block to slide along the outer wall of the fifth sliding rod, so that the distances of the two positioning blocks from the center of the positioning groove can be adjusted equidistantly to adapt to the use of internal gear rings of different sizes; by adjusting the position of the positioning block, this mechanism can easily adapt to internal gear rings of different sizes and specifications, ensuring the stability and accuracy of the internal gear ring during positioning, and improving the flexibility and versatility of the equipment.

[0020] 3. Through the combined use of the guiding surface, the positioning groove and the positioning block, the precise guiding and positioning of the internal gear ring during conveying are ensured, so that the center of the internal gear ring and the center of the through hole are on the same vertical line, achieving a high-precision center positioning effect.

[0021] 4. The internal gear ring that enters the cooling box is immersed in the quenching liquid at this time, so as to carry out quenching treatment. The chain plate conveyor drives the gear ring to be conveyed to one side close to the blanking frame. At this time, the lifting plate tilts, and the gear ring slides out through the blanking frame. The filter screen can drain the coolant attached to the gear ring into the liquid guide frame, and the liquid guide frame discharges the coolant back into the cooling box through the liquid inlet hole; this design enables the gear ring to continuously enter the cooling box for quenching treatment, improving the continuous operation ability of the production line. The lifting plate tilts driven by the chain plate conveyor, enabling the gear ring to smoothly slide out of the blanking frame, realizing automatic blanking after quenching, reducing manual operation, and improving efficiency. Through the combined use of the filter screen and the liquid guide frame, the coolant attached to the gear ring can be effectively drained into the liquid guide frame and discharged back into the cooling box through the liquid inlet hole, realizing the recycling of the coolant, reducing resource waste and environmental pollution.

The center of the inner gear ring and the center of the through hole 106 are on the same vertical line, realizing the central positioning of the inner gear ring;

[0059] By rotating the adjusting screw 314 to drive the connecting column 312 to move, the connecting column 312 drives the fixing rod 311 to slide along the inner wall of the limiting plate 315. When the fixing rod 311 moves, it drives the sliding sleeve 310 to move. The sliding sleeve 310 slides along the outer wall of the fixing rod 311. At this time, the positioning block 308 drives the slider 307 to slide along the outer wall of the fifth slide bar 305, so that the distances of the two positioning blocks 308 from the center of the positioning groove 302 can be adjusted equidistantly to adapt to the use of inner gear rings of different sizes;

[0060] When the chain plate conveyor 408 rotates, it drives multiple lifting plates 409 to move. When the chain plate conveyor 408 rotates, it drives the second connecting arm 209 to rotate. The second connecting arm 209 drives the first connecting arm 207 to swing. The first connecting arm 207 drives the clamping plate 205 to slide along the inner wall of the fourth slide bar 203. When the clamping plate 205 slides downward, it drives the quenching machine 210 to move downward. The temperature of the quenching machine 210 is controlled by the temperature controller 211. At this time, the inductor on the quenching machine 210 passes through the inner gear ring and extends into the through hole 106, thereby heating the inner gear ring;

[0061] After heating, the inductor of the quenching machine 210 moves upward out of the through hole 106. The supporting groove 410 at the end of the lifting plate 409 driven by the chain plate conveyor 408 squeezes the bottom end of the second blanking plate 125. At this time, the second blanking plate 125 slides towards the inner wall of the chute 124. At the same time, the third slide bar 129 slides along the second support block 131. When the second blanking plate 125 moves upward, it pushes the first blanking plate 122 to rotate around the second rotating shaft 123. When the first blanking plate 122 rotates, it drives the support plate 104 to rotate downward around the first rotating shaft 105 through the connecting shaft 115. The end of the support plate 104 squeezes the clamping column 110 until the support plate 104 disengages from the clamping column 110. At this time, the support plate 104 is tilted, so that the inner gear ring can slide out of the support plate 104 onto the first blanking plate 122, and the inner gear ring is conveyed to the lifting plate 409 through the second blanking plate 125;

[0062] The internal gear ring that enters the cooling box 401 is immersed in the quenching liquid at this time, so as to carry out quenching treatment. The chain plate conveyor 408 drives the gear ring to be conveyed to one side close to the blanking frame 405. At this time, the lifting plate 409 tilts, and the gear ring slides out through the blanking frame 405. The filter screen 407 can drain the coolant attached to the gear ring into the liquid guide frame 406. The liquid guide frame 406 re-drains the coolant into the cooling box 401 through the liquid inlet hole 404;

[0063] When the end of the support plate 104 rotates downward, it squeezes the installation frame 116 upward at its end. At this time, the installation frame 116 pushes the connecting rod 118 to slide upward along the first fixing block 117, so that the second spring 119 is compressed. When the installation frame 116 moves, it drives the baffle 121 to move upward, and blocks the next internal gear ring through the baffle 121;

[0064] When the lifting plate 409 disengages from the contact with the second blanking plate 125, under the elastic force of the second spring 119, the installation frame 116 squeezes the support plate 104. At this time, the support plate 104 squeezes and engages with the clamping post 110. At the same time, the baffle 121 slides into the connecting groove 108, and the next internal gear ring can move above the support plate 104.
