Description

Technical Field

[0001] This utility model relates to the field of friction pad processing technology, specifically a friction pad processing mold for cold rolling mills. Background Technology

[0002] As a crucial component in cold rolling mills, the quality and performance of friction pads largely depend on the precise operation of the processing dies. The performance of these dies directly affects the forming quality and performance of the friction pads, playing an indispensable role in the stable operation and increased production efficiency of cold rolling mills.

[0003] In practical applications, friction pads often require single or multiple grooves at their ends. These grooves are designed to meet the installation, connection, and functional requirements of the friction pads under different working conditions. However, this requirement introduces inconvenience into the manufacturing process, as different mold heads need to be replaced when machining friction pads with different groove shapes. Current machining molds involve overly cumbersome mold head replacement procedures, requiring extensive disassembly of parts of the mold structure. This increases the workload of operators, reduces mold head replacement efficiency, and impacts the overall machining progress of the friction pads.

[0004] Existing methods for changing die heads typically involve securing the die head with bolts. When changing the die head, each bolt must be removed individually, and after replacing it with the new die head, the bolts must be reinstalled. This process requires various tools, and each bolt removal and installation consumes significant time and effort, severely reducing the efficiency of die head changes and hindering the continuity and efficiency of friction pad processing.

[0029] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0030] This utility model discloses a machining mold for friction pads in a cold rolling mill, according to the attached... Figure 1-3As shown, the device includes a mold body 1, with a compaction component on top for compaction. A movable plate 2 is vertically slidably connected inside the mold body 1. A module replacement unit 4 is located inside the mold body 1, comprising a mold head 41, protrusions 42, and a fixing clip 43. The mold head 41 is mounted on the movable plate 2.

A support plate 46 is fixedly mounted on the output shaft of the lifting cylinder 3, and a connecting column 47 is fixedly mounted on the top of the support plate 46. The connecting column 47 is fixedly mounted to the movable plate 2.

[0032] In this embodiment, the first sealing ring 44 and the second sealing ring 45 are made of high-temperature resistant rubber, which can enhance the sealing performance inside the mold body 1. The support plate 46 supports the insert 434, ensuring that the insert 434 can move stably. A connecting column 47 is fixedly installed on the top of the support plate 46. The connecting column 47 is fixedly installed with the movable plate 2. The support plate 46 and the movable plate 2 are connected by the connecting column 47, so that the lifting cylinder 3 can stably drive the movable plate 2 to move. It should be noted that the insert 434 abuts against the end of the support plate 46, which means that the insert 434 can only move left and right in the preset direction, instead of rotating with the bidirectional screw 433, thus ensuring the effectiveness of the device.

[0033] According to the appendix Figure 1 , 4 As shown in Figure 5, further, it includes a mold body 1, a compaction component for compaction is provided on the top of the mold body 1, a movable plate 2 is vertically slidably connected inside the mold body 1, and a module replacement unit 4 is provided inside the mold body 1. The module replacement unit 4 includes a mold head 41, a protrusion 42 and a fixing clip 43.

[0034] The mold head 41 is set on the movable plate 2; the protrusions 42 are fixedly assembled on the bottom of the mold head 41, and the protrusions 42 are distributed in a rectangular array. The protrusions 42 are movably inserted into the interior of the movable plate 2; the fixing clip 43 is set on the bottom of the movable plate 2, and the fixing clip 43 is used to fix the protrusions 42 after they are inserted into the movable plate 2.

[0035] The fixing clip 43 includes a first fixing block 431, a second fixing block 432, and a double-acting screw 433. The first fixing block 431 is fixedly assembled on one side of the bottom of the movable plate 2; the second fixing block 432 is fixedly assembled on the other side of the bottom of the movable plate 2; the double-acting screw 433 is rotatably connected inside the first fixing block 431 and the second fixing block 432. The fixing clip 43 also includes an insert 434 and a hexagonal insert 435. The insert 434 is sleeved on the outer surface of the double-acting screw 433, the inserts 434 are symmetrically arranged, the inserts 434 are threadedly assembled with the double-acting screw 433, and the inserts 434 are movably engaged inside the protrusion 42; the hexagonal insert 435 is movably engaged inside the double-acting screw 433. The fixing clip 43 also includes a socket 436 and a rotating rod 437; the socket 436 is located inside the second fixing block 432, and the hexagonal rod 435 is movably inserted into the socket 436; the rotating rod 437 is fixedly mounted on one end of the hexagonal rod 435. The fixing clip 43 also includes an anti-detachment block 438 and a sliding groove 439; the anti-detachment block 438 is fixedly mounted on one end of the rotating rod 437; the sliding groove 439 is located inside the second fixing block 432, and the anti-detachment block 438 is slidably connected inside the sliding groove 439, with the end of the anti-detachment block 438 abutting against the inner wall of the sliding groove 439.

[0036] In this embodiment, when it is necessary to replace the mold head 41, pull the hexagonal insert 435 outward to disengage it from the inside of the insertion hole 436. The operator rotates the bidirectional lead screw 433. The bidirectional lead screw 433 rotates to move the symmetrically arranged inserts 434 away from each other. The inserts 434 disengage from the protrusion 42, releasing the fixation of the protrusion 42. At this time, the old mold head 41 can be removed.

[0037] Then, insert the protrusion 42 at the bottom of the new mold head 41 into the movable plate 2, rotate the bidirectional lead screw 433 in the opposite direction to move the insert 434 closer to each other, insert the insert 434 into the protrusion 42, and then push the hexagonal insert 435 into the insertion hole 436 to complete the fixing of the new mold head 41 and realize the quick replacement of the mold head 41.

[0038] The compaction components include a hydraulic press and a pressure plate. The raw material liquid is injected into the interior of the mold body 1.
