Description

Technical Field

[0001] The utility model relates to the technical field of steel back processing, in particular to a flattening device used for processing the steel back of a brake pad. Background Art

[0002] Brake pads, also known as brake leathers, are the most critical safety parts in the car's brake system. They are generally composed of a steel backing plate, an adhesive insulation layer and a friction block. The steel plate must be painted to prevent rust. The SMT-4 furnace temperature tracker is used to detect the temperature distribution of the coating process to ensure quality. In the production process of the brake pad steel back, the steel back with a certain curvature needs to be flattened. At present, domestic auto parts manufacturers generally use progressive forming + composite blanking + manual leveling to produce steel backs.

[0003] When the existing brake pad steel back is flattened, some debris will be generated. After the flattening device has been operating for a long time, a lot of waste chips will be generated on the workbench. If they are not cleaned up in time, it will affect the subsequent flattening operation of the brake pad steel back. Therefore, the staff is required to stop the machine to clean up these waste chips, which in turn affects the speed of the overall operation. At the same time, collecting these waste chips is also time-consuming and laborious. For this reason, a flattening device for brake pad steel back processing is proposed. Utility Model Content

The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0027] The following describes an embodiment of the utility model based on its overall structure.

[0028] A flattening device for processing the steel back of a brake pad, such as Figure 1-Figure 5 As shown, it includes a base body 100, a mounting base plate 110 is fixedly installed on the top of the base body 100, a lower pressing tool 120 is installed at the center of the upper surface of the mounting base plate 110, support columns 130 are fixedly installed at the four corners of the mounting base plate 110, an oil press 140 is fixedly installed on the top of the support column 130, an upper pressing plate 150 is fixedly installed at the output end of the oil press 140, a buffer assembly 200 is installed on the upper surface of the mounting base plate 110 on both sides of the lower pressing tool 120, and a collecting assembly 300 is provided at the front end of the lower pressing tool 120; the buffer assembly 200 includes a fixedly installed on the upper surface of the mounting base plate 110 at the lower pressing tool 120 The piston cylinders 230 on both sides have pistons 250 sleeved inside them, a piston rod 240 is fixedly connected to the center of the top of the piston 250, the top of the piston rod 240 extends through the top of the piston cylinder 230 and is fixedly installed with a lower extrusion block 280, a fixing plate 260 is fixedly installed at the bottom of the piston 250, a buffer spring 270 is fixedly installed at the fixing plate 260 and the bottom of the inner cavity of the piston cylinder 230, L-shaped fixing rods 210 are fixedly installed on both sides of the upper pressure plate 150, and the other ends of the two groups of L-shaped fixing rods 210 are fixedly connected to the upper extrusion block 220, and the upper extrusion block 220 is located directly above the lower extrusion block 280.

[0029] When the upper pressure plate 150 moves downward, it drives the L-shaped fixing rods 210 and the upper extrusion block 220 fixed on both sides to move downward. When the upper extrusion block 220 contacts the upper surface of the lower extrusion block 280, it starts to drive the lower extrusion block 280 and the piston rod 240 to move downward together, so that the piston rod 240 drives the piston 250 and the fixing plate 260 to move toward the bottom of the piston cylinder 230. At this time, the buffer spring 270 is squeezed and begins to compress, which plays a buffering role in the flattening operation, making the brake pad steel back plate flattening more stable, thereby increasing the service life of the overall device.

[0030] Please refer to Figure 2 , Figure 3 as well as Figure 5As shown, the collecting assembly 300 includes an air inlet pipe 310 fixedly connected to the outer bottom end of the two groups of piston cylinders 230, and the outer bottom end of the two groups of piston cylinders 230 is fixedly connected to the side of the air outlet pipe 320 away from the air inlet pipe 310. The other ends of the two groups of air outlet pipes 320 are fixedly connected to the same blow box 330, and the air outlet of the blow box 330 is arranged parallel to the upper surface of the lower pressure tool 120. A one-way air inlet valve is installed at one end of the air inlet pipe 310, a one-way air outlet valve is installed at one end of the air outlet pipe 320, and a stopper 340 is installed at the top of the inner cavity of the blow box 330. A support plate 350 is fixedly installed at the front end of the lower pressing tool 120, and two sets of air outlet pipes 320 extend through and extend above the support plate 350. The support plate 350 is fixedly connected to the two sets of air outlet pipes 320. A collection box 360 is fixedly installed on the upper surface of the mounting base plate 110 at the rear end of the lower pressing tool 120. A collection drawer 380 is slidably connected inside the collection box 360. The other end of the collection drawer 380 extends to the outside of the collection box 360 and is fixedly installed with a handle. An arc-shaped baffle plate 370 is fixedly installed on the side of the top of the collection box 360 away from the lower pressing tool 120.

[0031] As the piston rod 240 drives the piston 250 to move toward the bottom of the piston cylinder 230, the internal gas of the piston cylinder 230 is squeezed into the exhaust pipe 320 and finally blown out through the blow box 330. The stop block 340 is used to make the wind force blow toward the surface of the lower pressing tool 120, and the waste chips on the surface of the lower pressing tool 120 are blown into the collection drawer 380. After a period of time, the operator pulls out the collection drawer 380 and cleans the waste chips in a centralized manner to prevent the waste chips from accumulating on the surface of the lower pressing tool 120 and affecting the subsequent flattening operation of the brake pad steel back, thereby affecting the speed of the overall operation. When the upper pressing plate 150 moves upward, the elastic force of the buffer spring 270 itself is used to push the fixed plate 260, the piston 250 and the piston rod 240 to move toward the top of the piston cylinder 230, and a negative pressure is generated inside the piston cylinder 230. The external gas enters the piston cylinder 230 through the intake pipe 310, so that the subsequent blowing work can continue.

[0032] When in use, when the piston rod 240 drives the piston 250 to move toward the bottom of the piston cylinder 230, the internal gas of the piston cylinder 230 is squeezed into the exhaust pipe 320 and finally blown out through the blow box 330. The block 340 is used to direct the wind force to the surface of the lower press 120 for blowing, and the waste chips on the surface of the lower press 120 are blown into the collection drawer 380. After a period of time, the operator pulls out the collection drawer 380 and cleans the waste chips in a centralized manner to prevent the waste chips from accumulating on the surface of the lower press 120 and affecting the subsequent flattening operation of the brake pad steel back, thereby affecting the speed of the overall operation. The parts not involved in the device are the same as the prior art or can be implemented using the prior art.

The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples.
