Description

Technical Field

[0001] This utility model relates to a brake pad pre-production device, and more particularly to a disc brake pre-forming press and a brake production line that is used in conjunction with it. Background Technology

[0002] Chinese patent "A Brake Pad Press" (Publication No.: 219881278U), published on October 24, 2023, includes: a worktable, guide rods, a top plate, a controller, and a base. Multiple guide rods are installed on the top of the worktable, with their tips connected to the bottom of the top plate. The controller and base are also located on the top of the worktable. The press further includes a lower mold assembly, a hot pressing assembly, and an ejection assembly. The lower mold assembly is located on the top of the base, the ejection assembly is mounted on the top of the base, and the hot pressing assembly is mounted on the top plate. The press lays brake pad powder on the lower mold assembly. The hot pressing assembly works in conjunction with the lower mold assembly to perform hot pressing molding of the powder. The molded brake pad blank is then placed in the lower mold assembly. The lower mold assembly is then separated, and the ejection mechanism ejects the brake pad blank from the lower mold assembly, achieving rapid demolding and removal of the brake pad blank. This type of brake pad press can only process brake pads of a fixed thickness and cannot adjust the thickness as needed. If the brake pad thickness needs to be adjusted, a mold of a different specification must be used. Utility Model Content

[0016] To better understand the technical content of this utility model, the following examples are provided in detail.

[0017] like Figure 1 , Figure 2 , Figure 3 and Figure 4The embodiment of the disc brake preforming press of this utility model includes: a frame 1, a pressure plate 2 on the frame 1, a pressure plate driving device 3 connected to the pressure plate 2, the pressure plate driving device 3 being a hydraulic cylinder, a guide rod 4 on the frame 1, the pressure plate 2 passing through the guide rod 4 and sliding up and down along it, thereby playing the role of pressing the friction material in the mold.

[0018] The pressure plate 2 is equipped with a mold, which includes an upper mold 5 and a lower mold 6. The upper mold 5 is connected to the bottom of the pressure plate 2, and the lower mold 6 is located on the worktable of the frame 1. The lower mold 6 is equipped with a feeding groove 7, and the bottom of the feeding groove 7 is equipped with a positioning base plate. The lower mold 6 is equipped with a mold lifting device to move the positioning base plate relative to the mold. The mold lifting device includes a lifting column 8, which is connected to a lifting seat 9. The lifting seat 9 is movably connected to a lifting screw 10. The lifting screw 10 is driven by a lifting motor. The lifting motor drives the lifting screw 10 to rotate through gears, belts, or chains, so that the lifting column 8 drives the lower mold 6 to move up and down, thereby adjusting the depth of the feeding groove to accommodate brake pads of different thicknesses, or adjusting the thickness of each layer of two or more brake pads according to the settings to achieve the pressing of multi-layer brake pads.

[0019] The lower mold is equipped with a material spreading device, which includes a hopper 12 connected to a material spreading slide 13. The material spreading slide 13 is connected to a material spreading slide drive device, which includes a support frame 14 connected to the material spreading slide. The support frame 14 has a slide rack that meshes with a slide gear, which is connected to a slide drive motor 15. The material spreading slide drive device can also be replaced by a pneumatic cylinder, hydraulic cylinder, or electric cylinder. The bottom of the hopper has a discharge port to allow the friction material in the hopper to be poured into the material discharge groove. Slide grooves are provided on both sides of the lower mold, and material spreading sliders are provided on both sides of the material spreading slide. The material spreading sliders are located in the slide grooves, allowing the material spreading slide to move forward and backward along the lower mold under the push of the material spreading slide drive device.

[0020] The lower mold is also equipped with a steel backing placement device, which includes a steel backing slide 24, a steel backing placement groove 25 on the steel backing slide, and a steel backing slide drive device 23. The steel backing slide drive device is a cylinder. The steel backing slide drive device can also be a hydraulic cylinder, an electric cylinder, a rack and pinion, or a lead screw drive. Steel backing sliders are also provided on both sides of the steel backing slide, and the steel backing sliders are located in the slide groove, so that the steel backing slide can move forward and backward on the lower mold under the push of the steel backing slide drive device.

[0021] The control valve one connected to the pressure plate drive device, the lifting motor, the slide drive motor, and the control valve two connected to the steel back slide drive device are all connected to the controller. The controller controls the lifting and lowering of the pressure plate through control valve one to press the brake pad blank, and raises the pressure plate so that the robot or operator can remove the brake pad blank. The controller can adjust the displacement of the lifting motor according to a preset value, thereby controlling the depth of the feeding trough, thus realizing the pressing of multi-layer brake pads or brake pads of different thicknesses. It can also generate multi-layer brake pads with several layers having different material compositions, depending on its coordination with other feeding equipment. The controller drives the slide drive motor to slide the spreading slide along the lower mold in forward and reverse directions, thereby evenly distributing the friction material in the corresponding feeding trough below. The controller operates the steel back slide along the lower mold through control valve two, causing the steel back placed in the steel back placement slot to fall into the feeding trough. The controller is a PLC controller.

[0022] like Figure 5 The brake production line of this utility model includes: an automatic weighing machine 17 on one side of a disc brake preforming press 16, a curing device 18 on the other side of the disc brake preforming press 16, and a hot press 19 at the tail end of the curing device 18. A first robotic arm 19 is provided between the disc brake preforming press 16 and the curing device 18, a second robotic arm 20 is provided at the tail end of the curing device 18, an intermediate platform 21 is provided on one side of the second robotic arm 20, and a third robotic arm 22 is provided on one side of the intermediate platform 21. The curing device 18 is a chain plate curing oven.

[0023] In this invention, when pressing brake pad blanks, the controller adjusts the extension height of the mold lifting device according to a preset value. Then, the controller activates the steel back slide drive device to move the steel back transfer table above the material discharge trough, causing the steel back in the steel back placement slot to fall into the material discharge trough. Afterward, the controller resets the steel back placement device. Next, the controller instructs the automatic weighing machine to place the weighed friction material into the hopper of the spreading device. The controller then activates the slide drive motor to move the spreading slide into the material discharge trough. When the discharge port reaches above the material discharge trough, the friction material in the hopper begins to fall. As the spreading slide slide slides back and forth, the friction material is evenly distributed. Finally, the controller activates the pressure plate drive device to press the upper and lower molds together to form the brake pad blank. When pressing multi-layer brake pad blanks, the controller adjusts the extension height of the mold lifting device before pressing each layer according to the thickness of each layer. When pressing multi-layer brake pad blanks with different friction materials, the automatic weighing machine provides the required friction material for each layer according to a preset value. The first robotic arm is used to pick up the brake pad blanks that have been pressed by the disc brake preforming press and place them on the curing device. The curing device will preheat and cure the pressed brake pad blanks. Then, the second robotic arm will place the cured brake pad blanks on the intermediate platform. The third robotic arm will pick up the brake pad blanks on the intermediate platform and place them on the hot press for hot pressing to finally form disc brake pads.
