Description

Technical Field

[0001] The present invention relates to the technical field of automobile brake disc manufacturing, and in particular to a manufacturing device and a manufacturing process for a multi-point automobile brake disc. Background Art

[0002] To put it simply, the brake disc is a round plate that rotates when the car is moving. The brake caliper clamps the brake disc to generate braking torque. When you step on the brake, it is the brake caliper that clamps the brake disc to slow down or stop the car. The brake disc has a good braking effect and is easier to maintain than drum brakes. The brake disc is an essential component of all vehicle braking systems. It is fixed on the axle and rotates with the wheel. When braking, the brake pad is squeezed onto the brake disc by the push of the caliper piston. The friction between the brake pad and the brake disc reduces the wheel speed, thereby achieving the purpose of decelerating and braking the vehicle.

[0003] In the prior art, there is a multi-point automobile brake disc and brake disc manufacturing process with announcement number CN112815024B. The brake disc produced by this invention effectively solves the problem that the brake disc is susceptible to corrosion during use due to the single material used in its preparation, which leads to brake failure and traffic accidents.

[0004] However, although the above-mentioned automobile brake disc manufacturing device can perform manufacturing and processing operations on multi-point brake discs well when in use, the processing casting mold models corresponding to the existing brake discs are relatively single. During casting, the conversion effect of processing discs of different models is not good, so that when it is necessary to process brake discs of different sizes, the operator needs to frequently disassemble and replace the casting cavity mold, which reduces the overall efficiency of the manufacturing device in manufacturing brake discs of different sizes. Moreover, when converting brake discs of different models, the synchronous circulation cooling and demolding effect of the brake disc in the forging mold is not high, which reduces the convenience of unloading the forged brake disc, affects the efficiency of brake disc processing, and does not meet people's use needs. For this reason, we propose a manufacturing device and manufacturing process for multi-point automobile brake discs. Summary of the Invention

When it is necessary to adjust the casting of brake discs of different sizes, the rotation of the intermittent turntable 1204 drives the intermittent wheel 1207 to perform intermittent rotational motion. The rotation of the intermittent wheel 1207 drives the conversion frame 1211 to rotate synchronously and intermittently through the rotation of the connecting shaft 1210, so that the casting cavity molds 1212 of different sizes move to the bottom of the discharge pipe 7, so that the hard substrate particles, binder and borax mixed inside the mixing drum 5 are transported to the inside of the casting cavity mold 1212 for preliminary cooling and shaping movement.

[0074] like Figure 15As shown, the outer wall of the manufacturing equipment body 1 is fixedly connected to the first electric push rod 8 fixedly connected to the outer wall of the sliding frame 9, the outer wall of the sliding frame 9 is fixedly connected to the second electric push rod 10 fixedly connected to the bottom of the lifting box 11, the outer wall of the sliding frame 9 is provided with a refrigeration mechanism 17, the top of the refrigeration mechanism 17 is fixedly connected to the booster pump 18, the outer wall of the booster pump 18 is fixedly connected to the connecting pipe 19 rotatably connected to the connecting shaft 1210, the inner wall of the connecting shaft 1210 is provided with a first conveying cavity 20, and the inner wall of the conversion frame 1211 is provided with a second conveying cavity 20 connected to the first conveying cavity 20.

When the air compressor 32 is turned on, the gaseous refrigerant in the low-pressure pipeline is compressed to become a high-temperature and high-pressure state, so that the refrigerant in the pipeline generates a pressure difference to facilitate flow, and the high-temperature and high-pressure gaseous refrigerant is transported to the condenser 33 through the high-pressure pipeline. The condenser 33 dissipates heat through the generator fan to reduce the temperature of the gaseous refrigerant. The cooled gaseous refrigerant becomes a medium-temperature and high-pressure state under the action of high pressure, so as to absorb heat and cool down during the evaporation process. The medium-temperature and high-pressure liquid refrigerant after passing through the condenser 33 is filtered and dried by the liquid storage dryer 34 and transported to the expansion valve 35 for throttling process, thereby realizing the cooling and pressure reduction of the liquid refrigerant again, and controlling the refrigeration effect by adjusting the refrigerant flow rate. The low-temperature and low-pressure liquid refrigerant fully absorbs heat and vaporizes when passing through the evaporator box 36, cooling the air around the evaporator box 36 and becoming a low-temperature and low-pressure gaseous refrigerant again. The cooled air is blown into the air duct through the blower 37 and transported to the connected pump, while the low-temperature and low-pressure gaseous refrigerant flows back to the air compressor 32 through the expansion valve 35 to repeat the refrigeration process, thereby achieving the effect of repeated and continuous cooling and demolding of the brake disc.

Through the connection of the connecting gear 1203, the intermittent turntable 1204 is driven to rotate along the inner wall of the lifting box 11, which plays a role in driving the swing rod 1205 to rotate synchronously.

The limiting grooves 1208 are arranged on the movement trajectory of the sliding column 1206. An intermittent notch is provided at the connection between the outer wall of the intermittent turntable 1204 and the connecting groove 1209, which is beneficial for the sliding column 1206 to slide along the inner wall of the limiting groove 1208, thereby driving the intermittent wheel 1207 to rotate along the inner wall of the lifting box 11, thereby driving the conversion frame 1211 to intermittently switch the use direction.

[0089] Example 5:

[0090] Based on Examples 1, 2, 3, and 4, a manufacturing process for a multi-point automobile brake disc is further disclosed, comprising the following steps:

[0091] Step S1: transporting hard substrate particles, binder and borax into a mixing drum 5 for stirring and mixing, and the mixed raw materials are transported to the casting cavity mold 1212 through a delivery pipe 6;

[0092] Step S2: After the mold cavity 1212 is leveled, the raw material in the mold cavity 1212 is cooled and molded by the refrigeration mechanism 17;

[0093] Step S3: transporting the preformed product cooled and formed in the casting cavity mold 1212 to the pouring gate 15 of the melting tank 14, and pouring the preformed product in the casting cavity mold 1212 by the turning movement of the pouring gate 15;

[0094] Step S4: After the molten cast iron is poured into the mold in the casting cavity mold 1212 through the pouring gate 15, the brake disc substrate is obtained after cooling. The brake disc substrate is placed in the coating chamber 4, and the outer coating is sprayed on the surface of the brake disc substrate. After the outer coating cools and adheres, the multi-point automobile brake disc is obtained;

[0095] Step S5: The fully formed brake disc is circulated and cooled by the refrigeration mechanism 17 before demoulding and blanking.

[0096] The working principle of the present invention is as follows: first, the hard substrate particles, binder and borax are transported to the mixing drum 5 for stirring and mixing, and the mixed raw materials are transported to the casting cavity mold 1212 through the delivery pipe 6. When the brake disc is converted and forged through the casting cavity molds 1212 of different specifications, in order to improve the effect of synchronous conversion cooling and demoulding of the brake discs in the casting cavity molds 1212 of different specifications, the cold air generated by the refrigeration mechanism 17 is transported to the air delivery pipe 22 through the first delivery cavity 20 and the second delivery cavity 21, and the cold air in the air delivery pipe 22 is transported to the cooling chamber 31. The brake disc in the casting cavity mold 1212 is cooled and shaped, and the gas in the air pipe 22 is transported to the air cavity 24 to increase the pressure of the air cavity 24. Under the connection of the connecting block 25, the lifting rod 26 and the spring 27 are lifted, and the stripper plate 28 is driven to lift and demold the cooled and shaped brake disc. When the stripper plate 28 exceeds the exhaust pipe 29, the pressure in the air cavity 24 is relieved under the action of the pressure relief pipe 30, so that the stripper plate 28 is reset. This reciprocating process plays a role in cyclic cooling and demolding of the casting cavity molds 1212 with different specifications.

[0097] Secondly, the casting cavity mold 1212 is molded. When it is necessary to adjust the casting of brake discs of different sizes, the rotation of the intermittent turntable 1204 drives the intermittent wheel 1207 to perform intermittent rotation. The rotation of the intermittent wheel 1207 drives the conversion frame 1211 to rotate synchronously and intermittently through the rotation of the connecting shaft 1210, so that the casting cavity molds 1212 of different sizes are moved to the bottom of the discharge pipe 7, so that the hard base material particles, binder and borax mixed in the mixing drum 5 are transported to the inside of the casting cavity mold 1212 for preliminary cooling and shaping.

[0098] Next, when the mixed hard substrate particles, binder and borax are transported to the interior of the casting cavity mold 1212 for cooling, in order to improve the leveling effect of the raw material inside the casting cavity mold 1212 and the synchronous anti-drip effect on the top of the discharge pipe 7, the second servo motor 1301 is turned on to drive the lifting block 1303 to slide along the outer wall of the connecting frame 2 through the rotation of the threaded rod 1302. The sliding of the lifting block 1303 drives the leveling block 1306 fixedly connected to the telescopic rod 1305 to perform synchronous telescopic movement through the rotation of the pull rod 1304, thereby improving the surface flatness of the raw material inside the casting cavity mold 1212;

[0099] Again, when the sliding rack 9 is pushed to the side of the pouring gate 15 for pouring processing, the third servo motor 1601 can drive the melting box 14 fixedly connected to the rotating shaft 1603 to rotate synchronously by rotating the rotating gear 1602. At the same time, under the sliding of the connecting rack 1604, the sliding rod 1606 rotatably connected to the rotating rod 1605 is driven to perform synchronous telescopic movement, so that the two sets of anti-splash blocks 1607 slide relative to each other, and the pouring gate 15 is synchronously shielded and protected from the pouring area of ​​the casting cavity mold 1212.

[0100] Finally, after the molten cast iron is poured into the model in the casting cavity mold 1212 through the pouring port 15, the brake disc substrate is obtained after cooling. The brake disc substrate is placed in the paint chamber 4, and the outer coating is sprayed on the surface of the brake disc substrate. After the outer coating cools and adheres, a multi-point automobile brake disc is obtained.
