Description

Technical Field

[0001] This utility model relates to the field of film production technology, and in particular to an automatic cutting machine for rubber films for automotive brake cylinders. Background Technology

[0002] The diaphragm is a component of the vacuum booster in a car. The vacuum booster uses vacuum (negative pressure) to increase the force applied by the driver to the pedal. In the car's braking system, it plays a role in transmitting pressure. When the car brakes, air enters the brake chamber through the air intake. Under the action of air pressure, the diaphragm deforms, pushing the push rod and causing the brake adjusting arm to rotate the brake cam, pressing the brake shoe friction pads against the brake drum to generate braking. When the car releases the brakes, the compressed air in the brake chamber is discharged into the atmosphere through a dual-chamber brake valve or quick-release valve. The diaphragm and push rod return to their original state under the action of the spring. The diaphragm plays a crucial role. The performance of the rubber diaphragm in the air chamber directly affects the vehicle's braking performance. After the diaphragm is formed, its outer edge usually has some burrs, which need to be trimmed before use. Currently, this is mostly done manually, which is inefficient and produces poor quality.

[0021] Example 1:

[0022] See Figure 1 The present invention relates to an automatic cutting machine for rubber film of automotive brake cylinders, comprising a frame 1 and a cutting mechanism for cutting rubber film.

[0023] Among them, see Figure 1 , Figure 2 and Figure 4 The cutting mechanism includes a lower clamping mold 2 and an upper clamping mold 3 disposed on the upper side of the lower clamping mold 2. The lower clamping mold 2 has a lower mold cavity 21, and the upper clamping mold 3 has an upper mold cavity 31. The lower mold cavity 21 and the upper mold cavity 31 together form a clamping mold cavity adapted to the rubber membrane. The outer periphery of the clamping mold cavity is flush with the outer periphery of the rubber membrane, and the outer periphery of the clamping mold cavity has a side opening for exposing excess burrs on the outer periphery of the clamping mold cavity. The lower side of the lower clamping mold 2 is provided with a burr removal mechanism for cutting off the burrs exposed from the side opening of the clamping mold cavity. The frame 1 is provided with a mold driving mechanism for driving the upper clamping mold 3 to move away from and closer to the lower clamping mold 2. The lower side of the lower clamping mold 2 is also provided with an elastic component for driving the lower clamping mold 2 to move closer to the upper clamping mold 3. In this embodiment, the rubber film to be cut is placed in the lower mold cavity 21, and then the automatic cutting machine is started. The mold drive mechanism drives the upper clamping mold 3 to move horizontally towards the lower clamping mold 2. During the horizontal movement, the upper clamping mold 3 and the lower clamping mold 2 close together, thereby clamping and fixing the rubber film in the clamping mold cavity. Excess burrs on the edge of the rubber film are exposed from the side opening. The mold drive mechanism continues to drive the upper clamping mold 3 to move downward, and drives the lower clamping mold 2 to move together. The lower clamping mold 2 compresses the elastic component. During the downward movement, the burrs come into contact with the burr removal mechanism and are removed. Then the mold drive mechanism resets, and the lower clamping mold 2 returns to the origin under the action of the elastic component. The upper clamping mold 3 separates from the lower clamping mold 2, and the rubber film can be taken out. This embodiment can complete the fully automatic cutting of burrs on the rubber film. It has a high degree of automation, reduces the intensity of manual labor, improves the cutting quality, and reduces the scrap rate.

[0024] See Figure 1 The frame 1 includes a base plate 11 and a top plate 12, with a plurality of support rods 13 provided between the base plate 11 and the top plate 12. The frame 1 has a simple structure, strong stability, and low cost.

[0025] See Figure 1 , Figure 2 and Figure 3 The mold driving mechanism includes a vertically arranged drive cylinder 4 and two first directional slide rods 5 arranged in the same direction as the drive cylinder 4. The first directional slide rods 5 are slidably connected to the top plate 12. The drive cylinder 4 drives the upper clamping mold 3 to rise and fall, and the first directional slide rods 5 can play a directional role and improve stability.

[0026] See Figure 1 , Figure 2 , Figure 4The burr removal mechanism includes an annular cutter 9 located on the lower side of the lower clamping mold 2. The annular cutter 9 is sleeved on the outer periphery of the lower clamping mold 2 and fixedly connected to the frame 1, with the cutting edge of the annular cutter 9 facing upwards. When the mold driving mechanism drives the lower clamping mold 2 to descend, the burrs can contact the cutting edge of the annular cutter 9, thereby removing the burrs. All burrs can be removed in one go, resulting in higher efficiency.

[0027] See Figure 4 The elastic component includes several vertically arranged second directional slide rods 6 and a fixing plate 7 located on the lower side of the lower clamping mold 2. The second directional slide rods 6 are fixedly located on the lower side of the lower clamping mold 2 and slidably connected to the fixing plate 7. A return spring 8 is sleeved on the second directional slide rod 6 for driving the lower clamping mold 2 to translate towards the upper clamping mold 3.

[0028] Example 2:

[0029] See Figure 2 Based on Embodiment 1, the cutting edge of the annular cutter 9 is angled for easier cutting.

[0030] The working process of this utility model:

[0031] In operation, the automatic cutting machine for automotive brake cylinder rubber films is used by placing the rubber film to be cut into the lower mold cavity 21, then starting the automatic cutting machine. The mold drive mechanism drives the upper clamping mold 3 to move horizontally towards the lower clamping mold 2. During the horizontal movement, the upper clamping mold 3 and the lower clamping mold 2 close together, thereby clamping and fixing the rubber film in the clamping mold cavity. Excess burrs on the edge of the rubber film are exposed from the side opening. The mold drive mechanism continues to drive the upper clamping mold 3 to move downward, and also drives the lower clamping mold 2 to move together. The lower clamping mold 2 compresses the elastic component. During the downward movement, the burrs come into contact with the burr removal mechanism and are removed. Then the mold drive mechanism resets, and the lower clamping mold 2 returns to the origin under the action of the elastic component. The upper clamping mold 3 separates from the lower clamping mold 2, and the rubber film can be removed.
