Detailed Description
The invention is further described below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
The automatic pushing and filling device for the partition plate of the drum brake pad hot-pressing mold comprises a pushing device 4 and a partition plate filling device 5.
As shown in fig. 1, the pushing device 4 includes a carriage 403 that can be driven by a first rodless cylinder 402 to move out of or into the space between the lower die holder 103 and the hot press base 104, a plurality of slide bars 404 that run along the moving direction of the carriage 403 are fixedly connected to the carriage 403, and the gaps 405 between the slide bars 404 in the same axial direction are equal, and the length of the gap is matched with the brake pad 410 and the partition 411, so as to clamp the partition 411 and the brake pad 410 pressed above the partition 411. Each slide bar is gradually raised from the hot press to the pushing direction (namely, the right end in the direction of the drawing is slightly lower than the partition 411, and the left end in the direction of the drawing is slightly higher than the partition 411) so as to ensure that the brake pad 410 can be smoothly pushed out from the slide bar 404 without being blocked by the slide bar 404, and the partition 411 is blocked by the slide bar without being pushed out. When the carriage 403 is moved between the lower die holder 103 and the hot press base 104, the slit 405 between the slides corresponds to receive the spacer 411 inserted through the mold cavity by the spacer loading device 5. The two sides of the carriage are fixedly connected with the sliding blocks of the linear guide rail 412, the linear guide rail 412 is fixed on the push-out frame body 401, the first rodless cylinder 402 is installed in the middle of the push-out frame body 401, and the sliding table of the first rodless cylinder 402 is fixedly connected with one end of the carriage 403.
A push plate bracket 408 spanning over the movement space of the carriage 403 is slidably disposed on the push-out frame 401 to avoid interference with the movement of the carriage 403. Two ends of the push plate bracket 408 are respectively and correspondingly installed on the sliding tables of the two second rodless cylinders 406, and the two second rodless cylinders 406 are fixed on the push-out frame body 401. The push plate holder 408 is driven by a second rodless cylinder 406 to reciprocate in the same direction as the carriage slides. Two push plates 409 are hinged on the push plate bracket 408.
As shown in fig. 2, two protrusions 407 are fixedly disposed at one end of the push-out frame 401 close to the hot press base 104, the protrusions 407 are respectively located at two sides of the carriage 403 to avoid interference with the movement of the carriage 403, and the protrusions 407 can contact with a push plate 409 on a push plate support 408 sliding through the position, so as to push the push plate 409 to rotate around the push plate support 408. The push plate bracket 408 is further provided with a pin shaft 40801 for limiting the rotation angle of the push plate 409 after the push plate 409 is separated from the bump, when the push plate 409 is moved to the vertical position under the action of gravity when the push plate bracket 401 moves towards the direction (namely the push direction) different from that of the hot press base 104 to enable the push plate 409 to be separated from the bump 407, the push plate 409 is limited at the vertical position by the pin shaft 40801, and when the push plate 409 is kept at the vertical position, the bottom of the push plate 409 is lower than the brake pad 410 on the carriage 403 and higher than the partition 411, so that the push plate can be contacted with the brake pad to push.
When the push plate bracket 408 is driven by the second rodless cylinder 406 to move towards the direction of the hot press base 104 until the push plate 409 contacts the bump 407, the bump enables the push plate to rotate until the plane of the push plate 409 is in a horizontal state like a cam mechanism, so that the yielding function is realized, and the interference of the push plate 409 on the movement space of the lower planker 403 is avoided; when the push plate bracket 408 moves towards the push-out direction, the push plate 409 swings downwards under the action of gravity after being separated from the protrusion 407, and when the push plate swings to the vertical position, the push plate is stopped by the pin 40801 fixed on the push plate bracket 408 and does not rotate any more, so that the push plate bracket 408 is kept at the vertical position and can be in contact with the brake pad to push the brake pad to move towards the push-out direction.
The push-out device 4 works:
when a pressing cycle is completed, the lower die holder 103 is raised a certain distance (slightly greater than the thickness of the layer of partition plate plus the layer of brake pad) to provide a pushing space for the pushing device 4. The first rodless cylinder 402 drives the carriage 403 to move out of a gap space between the lower die holder 103 and the hot press base 104, and the carriage 403 moves in the push-out direction to a layer of partition 411 at the lowest of the lower die holder 103 and a layer of pressed brake pad 410, and the layers of the partition 411 and the layer of the pressed brake pad 410 are all moved to a second station along with the carriage 403, namely, a blanking position for unloading the pressed and formed brake pad (at this time, other layers of partitions and the layers of brake pads in the hot press 1 correspondingly move downwards by one layer, and are continuously remained in the hot press 1 for circulating heat preservation and pressure maintenance until a set heat preservation and pressure maintenance time is reached, and the carriage is pushed downwards to the. Then the second rodless cylinder 406 drives the push plate bracket 408 to drive the push plate 409 to move towards the pushing-out direction from the initial position, when the push plate 409 is separated from the bump 407, the push plate 409 rotates downwards to the vertical position and contacts with the pin 40801, the push plate 409 cannot rotate continuously, and the vertical push plate 409 pushes the brake pad 410 to move towards the pushing-out direction to the conveying line.
After the partition 411 on the carriage 403 at the blanking position is clamped and taken away by the partition filling device 5, the empty carriage 403 is driven by the first rodless cylinder 402 to move into the first station space between the lower die holder 103 and the hot press base 104 again. At the same time or subsequently, the second rodless cylinder 406 drives the push plate support 408 to drive the push plate 409 to move towards the direction of the hot press base 104 until the push plate 409 contacts the bump 407, the bump 407 blocks the push plate 409, so that the push plate 409 rotates until the push plate 409 is lifted to be in a horizontal state, the push plate support 408 resets to an initial position, and a space is provided for moving the push plate 403 out of the mold again.
After the vacant carriage 403 is moved into the first station space between the lower die holder 103 and the hot press base 104, the lower die holder 103 is lowered to be closed with the hot press base 104. After the brake pad powder is filled into the cavity of the lower die holder 103 and is scraped, the clapboard filling device 5 correspondingly fills the layer of the clapboards 411 which are clamped and taken away to the uppermost layer in the cavity of the lower die holder 103 at the first station.
Referring to fig. 3, the spacer filling device 5 is used to clamp all the spacers 411 on the carriage 403 at the blanking position, and lift and move the spacers to a position right above the lower die base 103 at the first station, so as to accurately fill the spacers into the corresponding mold cavities.

A lifting fixing plate 50806 is fixed between the two guide rods 50801, so that the lifting fixing plate 50806, the two guide rods 50801 and the pressing block 50807 form a fixed body, piston rods of the two lifting cylinders 50805 are correspondingly and fixedly connected with two ends of the lifting fixing plate 50806, a cylinder body of the lifting cylinder 50805 is fixedly connected with the connecting rod 506, and the lifting cylinder 50805 drives the guide rods 50801 to vertically slide along the linear guide 50802 relative to the connecting rod 506, so that the guide rods 50801 can be lifted.
The two guide rods 50801 are connected with a plurality of paired clamping plates in a sliding manner, and the number of pairs of the clamping plates is the same as the number of columns for clamping the partition plates between the same slide bars on the carriage.
