Description

Technical Field

[0001] The present invention relates to the technical field of brake pad hot pressing, and in particular to a full-automatic brake pad hot pressing forming machine. Background Art

[0002] A hot press is a device that heats two pre-tinned parts with flux to a temperature high enough to melt and flow the solder. After solidification, a permanent electrical and mechanical connection is formed between the parts and the solder. Existing brake pads are generally composed of steel plates, adhesive thermal insulation layers, and friction blocks. The thermal insulation layer is composed of a material that does not conduct heat and is used for heat insulation. The friction block is composed of friction material and adhesive. When braking, it is squeezed on the brake disc or brake drum to generate friction, thereby achieving the purpose of deceleration and braking of the vehicle. The brake pad manufacturing process is mostly to put the evenly mixed friction material into a mold and press it into a friction pad through a hot press. However, during the brake pad manufacturing process, whether the friction material and adhesive put into the mold are evenly distributed on the steel plate mold will directly affect the density of the pressed product, and whether the inside of the hot pressing hole is clean directly affects the distribution of the friction material on the mold.

[0030] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0031] See also Figure 1 The present invention provides a fully automatic brake pad hot pressing forming machine, which includes a support assembly 1, which includes a base 11, a support rod 12 and a cross plate 13; the support rod 12 is fixed on the base 11, and the cross plate 13 is fixed on the upper end of the support rod 12; it also includes a hot pressing assembly 2, a slag cleaning assembly 3 and a calibration assembly 5.

[0032] The hot pressing assembly 2 includes a lower mold 21, a forming cylinder 211, a cylinder 22 and an upper mold 221; the lower mold 21 is fixed on the base 11, and a forming cylinder 211 is provided in the lower mold 21. The cylinder 22 is fixed on the horizontal plate 13, and the telescopic end of the cylinder 22 is fixed with an upper mold 221 that cooperates with the lower mold 21 and the forming cylinder 211; two air holes 212 are opened on the outer periphery of the forming cylinder 211.

[0033] The slag cleaning assembly 3 includes a first driving part 31, a sealing plate 32, an air supply part 33 and a slag collecting box 334; the sealing plate 32 is rotatably connected to the outer periphery of the forming cylinder 211 and is provided with ventilation holes 322 that cooperate with the two air holes 212; the first driving part 31 is arranged in the lower mold 21 and engages with the sealing plate 32, and the sealing plate 32 can be located in a first position and a second position. When the sealing plate 32 is in the first position, the air holes 212 are connected with the ventilation holes 322, and when the sealing plate 32 is in the second position, the air holes 212 and the ventilation holes 322 are misaligned; the air supply part 33 is installed on the base 11, and its air supply end is connected with one of the ventilation holes 322. The slag collecting box 334 is installed in the base 11 and is connected with the other ventilation hole 322 through a hose.

[0034] When the staff needs to use the equipment to hot-press the brake pads, they need to clean the forming cylinder 211 in the lower mold 21. The cleaning method is that the first driving part 31 drives the sealing plate 32 to rotate. When the through hole on the sealing plate 32 coincides with the air hole 212 on the forming cylinder 211, the forming cylinder 211 is in a state of connection with the outside world. The air supply part 33 provides wind to the inside of the forming cylinder 211. Since the air holes 212 are distributed in a centrally symmetrical manner, when the air supply part provides wind to the inside of the forming cylinder 211, it can effectively clean the impurities inside the forming cylinder 211, and the impurities in the cleaning dead corners are concentrated and flow into the slag collecting box 334 for centralized treatment, which greatly improves the cleaning efficiency and ensures the subsequent hot pressing effect of the brake pads.

[0035] To improve the alignment efficiency between the forming cylinder 211 and the sealing plate 32, refer to Figure 3 、 Figure 4 、 Figure 5 and Figure 6 In a preferred embodiment, a first mounting groove 213 is provided on the forming cylinder 211 and on both sides close to the air hole 212, and a second mounting groove 323 is provided on the sealing plate 32 and on both sides of the ventilation hole 322; a calibration component 5 is provided in the first mounting groove 213 and the second mounting groove 323, and the calibration component 5 includes an infrared transmitting probe 51 and an infrared receiving probe 52; the first mounting groove 213 is provided with an infrared transmitting probe 51, and the second mounting groove 323 is provided with an infrared receiving probe 52.

[0036] Among them, the infrared emitting probe 51 model is 904NM and the infrared receiving probe 52 model is CHQ1838D. The infrared emitting probe 51 is set in the first mounting groove 213 to emit infrared light. When the sealing plate 32 is rotating, and the infrared receiving probe 52 in the second mounting groove 323 receives the infrared light, it indicates that the positions of the air hole 212 and the ventilation hole 322 coincide with each other. At this time, the air supply part provides gas, which can effectively clean the inside of the forming cylinder 211, greatly improving the calibration efficiency between the sealing plate 32 and the forming cylinder 211.

[0037] To improve the coordination efficiency between the first driving part 31 and the air supply part 33, please refer to Figure 1 、 Figure 2 、 Figure 5 and Figure 7In a preferred embodiment, the first driving part 31 includes a motor 311 and a gear disc 312. The motor 311 is installed in the lower mold 21 and a gear disc 312 is fixed at its output end. The sealing plate 32 is provided with a tooth groove 321 that engages with the gear disc 312. The air supply part 33 includes a fan 331, a diverter pipe 332 and an air jet hose 333; the fan 331 is installed on the back of the base 11, and the air outlet end of the fan 331 is connected to the diverter pipe 332. The end of the diverter pipe 332 is connected to the air jet hose 333, and the end of the air jet hose 333 is connected to one of the ventilation holes 322.

[0038] The motor 311 drives the toothed disc 312 to operate, and the toothed disc 312 engages with the tooth groove 321 on the outer periphery of the sealing plate 32, thereby driving the sealing plate 32 to perform circular motion on the outer periphery of the forming tube 211. When the air hole 212 and the ventilation hole 322 are located at the same position, the fan 331 provides wind force to the inside of the diversion pipe 332, and guides the air flow from the ventilation hole 322 into the air hole 212 through the jet hose 333, and blows the impurities inside the forming tube 211, so that the impurities enter the slag collecting box 334 through the other air hole 212 and the ventilation hole 322, thereby completing the collection of impurities.

[0039] To improve the cleaning of the upper end surface of the lower mold 21, please refer to Figure 1 、 Figure 2 and Figure 8 In a preferred embodiment, a brushing assembly 4 for cleaning the lower mold 21 is provided on the base 11; the brushing assembly 4 includes a second driving part 41, a connecting rod 42 and a scraper 43; the second driving part 41 is installed in the base 11, and the second driving part 41 is provided with an axially movable connecting rod 42, and the end of the connecting rod 42 is fixed to a scraper 43 for cleaning the surface of the lower mold 21. The second driving part 41 includes a motor 411, a screw rod 412 and a screw block 413; the motor 411 is fixed in the base 11, and a screw rod 412 is fixed to the output end of the motor 411, and a screw block 413 is threadedly connected to the screw rod 412. Connecting rods 42 are fixed on both sides of the screw block 413, and one end of the two connecting rods 42 passes through the base 11 and is connected to the scraper 43. The connecting rod 42 is an L-shaped rod body, and a slide is provided on the inner wall of the base 11, in which the connecting rod 42 is slidably connected, and a flexible scraper is fixed to the lower end of the scraper 43.

[0040] The motor 411 drives the screw rod 412 to operate, and the screw rod 412 drives the screw rod to move axially on the screw rod 412. Since connecting rods 42 are fixed at both ends of the screw block 413, and a scraper 43 is fixed between the two connecting rods 42, when the screw block 413 drives the connecting rod 42 to move, the scraper 43 is driven to move synchronously. When the scraper 43 moves horizontally, the impurities and dust on the upper end surface of the lower mold 21 can be cleaned. Some impurities enter the forming cylinder 211 and are centrally cleaned by the slag cleaning component 3. The others fall from the upper end of the lower mold 21 under the scraping of the scraper 43, which greatly improves the cleaning efficiency of the lower mold 21 by the staff, thereby ensuring the hot pressing quality of the brake pad.

[0041] In order to better understand the present invention, the following Figures 1-8 The working process of the fully automatic brake pad hot pressing molding machine of the present invention is described in detail: when the staff needs to hot press the brake pad, first clean the surface of the lower mold 21, start the motor 411 to drive the screw 412 to operate, the screw 412 drives the screw block 413 to move axially on the screw, and cleans the upper end of the lower mold 21 with the connecting plate and the scraper 43, and processes the dust and impurities on the upper end of the lower mold 21 to the base 11 or drop into the molding cylinder 211. When the cleaning is completed, start the motor 311, the motor 311 drives the gear plate 312 to rotate, and the gear plate 312 drives the sealing plate 32 to rotate by cooperating with the tooth groove 321. While the sealing plate 32 rotates on the outer periphery of the molding cylinder 211, the infrared The transmitting probe 51 emits light outward. When the infrared receiving probe 52 in the second mounting groove 323 on the sealing plate 32 receives the infrared light, it indicates that the positions of the air hole 212 and the ventilation hole 322 coincide with each other. The fan 331 provides wind power, and the wind power enters the jet hose 333 through the diversion pipe 332, and blows air into the air hole 212 through the ventilation hole 322. Since there are two air holes 212 and two ventilation holes 322, when one air hole 212 is blown by the air flow, impurities and air flow will move toward the second air hole 212, and finally enter the second ventilation hole 322 and the hose, and are introduced into the slag collecting box 334 by the hose for centralized collection, thereby ensuring that the interior of the forming cylinder 211 is clean and free of impurities, greatly improving the work efficiency of the subsequent brake pads in the hot pressing process.

[0042] The specific embodiments of the present invention described above do not limit the scope of protection of the present invention. Any other corresponding changes and modifications made based on the technical concept of the present invention should be included in the scope of protection of the claims of the present invention.
