Detailed Description

The invention is further described with reference to the accompanying drawings, the following examples are only for better clarity of the technical solution of the invention, and the protection scope of the invention is not limited thereby.

As shown in figures 1 and 2, the feeding device of the drum brake pad hot-press forming die is used for spraying a release agent into a cavity of a lower die holder 103 of a hot press, putting powder into the cavity and leveling the powder, integrates three functions of spraying the release agent, feeding and leveling the powder into bodies, and is simple in structure because the position of the feeding device is controlled by feed screw and nut mechanisms.

The feeding device of the drum brake hot-press forming die comprises a hopper 310, an arc scraper 312 and a nozzle 320.

The hopper 310 is fixed to the hopper through a plurality of connecting plates 309, the number of the hoppers corresponds to the number of the die cavities, the positions of the hoppers correspond to the upper and lower portions of the die cavities, the bottom of each hopper are fixedly connected with a bottom plate 306 horizontally placed at 1, the bottom of each hopper corresponds to the bottom of the hopper 310, two fan-shaped materials 0314 are symmetrically installed at the bottom of each hopper, a rotating shaft 317 is fixedly connected to each material 2314, each material 3314 is hinged to the bottom plate 306 through the rotating shaft, a material oscillating bar 313 with a waist-shaped groove is fixedly connected to a 8 end of the rotating shaft, a set angle is formed between the oscillating bar 5 and a surface of the material , when the material oscillating bar 313 is at an initial position, the material 0314 is in a closed state, the angle is set to be about 40 degrees in the embodiment, a lug 318 is fixedly connected to the hopper, a cylinder body of the material opening and closing cylinder 315 is fixed to the lug 318, a piston rod of the material connecting rod 316 is fixedly connected to the piston rod of the material .

When the material opens and closes the cylinder 315 to drive the material connecting rod 316 to move downwards, the material connecting rod 316 slides along the waist-shaped groove of the material swing rod 313 to force the material swing rod 313 to drive the rotating shaft to rotate, so that the material 314 where the rotating shaft is located rotates, and the material 314 is opened downwards to realize discharging.

The taper plate 319 is longitudinally arranged at the middle position of the bottom of the hopper, and has the functions that is that the material is attached to the taper plate when closed, the leakage of the material at the joint of the two joints is avoided, and secondly, when the powder falls by the dead weight, the central part falls fast, the powder falls into the cavity of the die, the central part is stacked higher, and the phenomenon that the powder is gentle after the taper plate is arranged.

Guide rails 305 are fixed on two sides of the connecting plate 309 respectively, a sliding block 308 is fixed on the feeding frame body 201, the guide rails 305 do linear motion relative to the sliding blocks, sets of lead screw bearing seats 303 are further fixedly installed on the feeding frame body 201, lead screws 301 are installed on the bearing seats 303, ends of the lead screws 301 are connected with servo motors 304 through couplings, and lead screw nuts 302 are fixedly connected with hopper bottom plates 306 and can drive the hoppers to reciprocate towards the direction of the hot press.

A plurality of nozzles 320 are arranged on the side of each hopper 310 facing the hot press, the nozzles 320 are communicated with through a pipeline 307 and are connected with a release agent pump system, a cylinder body of a strickle rodless cylinder 311 is fixedly arranged at any position between the hoppers which are arranged in parallel and face the hot press, an arc-shaped scraper 312 corresponding to the outer arc surface of the brake pad is fixedly connected to a sliding table of the rodless cylinder 311, and the arc-shaped scraper 312 corresponding to the outer arc surface of the brake pad faces downwards.

The working process of the feeding device is as follows:

when receiving a feeding command, the servo motor 304 drives the hoppers to move towards the direction of the hot press through the screw rod nut mechanism, a stroke switch which can start the operation of the release agent pump is arranged on the side of each mold cavity facing the feeding device 2, another stroke switch which can correspondingly close the release agent pump is arranged on the other opposite side of each hopper, the stroke switch (not shown in the figure) at the position is triggered when each hopper moves to the side position of the mold cavity which can vertically correspond to the of each hopper, the release agent pump is started to operate, the nozzles spray the release agent towards the mold cavities, and when each hopper moves to the position which completely vertically corresponds to the corresponding mold cavity , another stroke switch at the other side of each mold cavity is triggered, the release agent pump stops operating, and the nozzles stop spraying.

At this time, the servo motor 304 stops working, meanwhile, the material opens and closes the piston rod of the air cylinder 315 to move downwards, the material is opened through the link mechanism, the powder falls into the mold cavity, the piston rod is reset after the time delay, and the material 314 is closed.

Then the servo motor 304 works to drive the hopper to move for a set distance towards different directions of the hot press, so that the arc-shaped scraper 312 moves to be close to the middle position of the corresponding die cavity, the sliding table of the rodless cylinder 311 drives the arc-shaped scraper 312 to move for a set depth towards the die cavity, so that the arc-shaped scraper 312 can be in contact with powder in the die cavity, the servo motor 304 drives the hopper to move towards the direction of the hot press again to drive the arc-shaped scraper 312 to move to the boundary in the die cavity to scrape the powder, the servo motor 304 drives the hopper to move towards different directions of the hot press again to drive the arc-shaped scraper 312 to move to another boundary in the die cavity to scrape the powder, then the sliding table of the rodless cylinder 311 resets upwards to drive the arc-shaped scraper 312 to move out of the die cavity to reset, and the servo motor 304 continues to drive the hopper to move towards different directions to return to the initial feeding position to weigh and charge the powder again, thereby automatically completing the spraying, feeding and scraping operations.

The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
