The working principle is as follows: firstly, a drum brake block 24 to be cut is placed between a top supporting clamping seat 25 and a bottom supporting clamping seat 23 in a fixed adjusting device 4 on one side, far away from a positioning adjusting device 5, of a mounting adjusting frame 6, then a first motor 10 is started to drive a driving gear disc 11 to rotate, the rotating driving gear disc 11 drives a rotating adjusting gear disc 9 to rotate by a specified angle, so that the top supporting clamping seat 25 and the bottom supporting clamping seat 23, in which the drum brake block 24 is placed, are rotated to one side, near the positioning adjusting device 5, and at the moment, the bottom supporting clamping seat 23, the top supporting clamping seat 25 and the drum brake block 24 are in a horizontal state (shown in figure 1), then a hydraulic cylinder 1 is started to drive a sliding adjusting supporting table 3 to slide forwards by a specified distance along a track plate 2, and at the moment, the drum brake block 24 is firstly contacted with the outer wall of a guide buffer plate 19, when the drum brake block 24 moves to the extrusion blocking adjusting plate 13 through the buffering and guiding of 19, the outer end of the drum brake block 24 contacts with the outer end face of the extrusion blocking adjusting plate 13, and the outer end of the drum brake block 24 is extruded through the extrusion blocking adjusting plate 13, so that the drum brake block 24 slides along the bottom support clamping seat 23 to the inside of the bottom support clamping seat 23 and compresses the extrusion push plate 30, at this time, after the drum brake block 24 slides for a certain distance along the horizontal smooth outer end face of the extrusion blocking adjusting plate 13, the second motor 27 is started to drive the first driving rod 35 to rotate, the rotating first driving rod 35 is driven by the second motor 27, the two first driving rods 35 can synchronously

contracted to the inside of the bottom support clamping seat 23, so that the clamping of the top support clamping seat 25 and the bottom support drum brake 24 can not be influenced, make expose at the outside drum brake block 24 of top support cassette 25 and bottom support cassette 23 in-process drum brake block 24 of cutting firm can not the displacement, and can pass through slide adjusting plate 16 through test and regulation before cutting drum brake block 24 and extrude the position that keeps off regulating plate 13 and direction buffer plate 19 along the upper end slide adjusting of support frame 20, make extrusion keep off the fender regulating plate 13 to the fender of drum brake block 24 and extrude drum brake block 24 to the inside gliding distance of bottom support cassette 23 can adjust and extremely, make the drum brake block 24 that can cut out various specifications, and the size specification between the same batch of drum brake block 24 that cuts is the same, through setting up positioning adjustment device 5 in the in-process that this device used, can play the spacing fender regulation through direction buffer plate 19 in positioning adjustment device 5 and extrusion fender regulating plate 13 and press The function, make the drum brake block 24 expose the same distance outside the top support cassette 25 after the baffle extrusion adjustment through the guide buffer plate 19 and the extrusion baffle adjusting plate 13, thus leave the drum brake block 24 between the top support cassette 25 and the bottom support cassette 23 after cutting the drum brake block 24 along the outer wall of the top support cassette 25 by the external cutting device, and can conveniently adjust and control the partial size of the drum brake block 24 exposed outside the top support cassette 25 and the bottom support cassette 23 by adjusting the position of the extrusion baffle adjusting plate 13 according to the size to be cut, through setting up the fixed adjusting device 4, the top support cassette 25 and the bottom support cassette 23 in the fixed adjusting device 4 can play the role of spacing placement to the drum brake block 24, insert the drum brake block 24 between the top support cassette 25 and the bottom support cassette 23, and control the sliding adjustment support platform 3 to slide along the track plate 2 by the hydraulic cylinder 1, at this moment can drive the top support cassette 25 and the bottom support cassette 23 and the middle part of the drum brake block 24 and make the extrusion baffle adjusting plate move along the track plate 2 through the extrusion baffle plate 13, thus make the extrusion baffle plate support the extrusion baffle plate 23 firmly contact with the extrusion baffle plate 23 through the extrusion baffle plate 13, thereby make the extrusion baffle plate support the extrusion adjusting plate 13 and the extrusion baffle plate support plate 13, make the extrusion baffle plate support the drum brake block support plate support the drum brake block 23 firmly through the extrusion baffle plate 13, thereby make things convenient for outside cutting device to expose at the outside drum brake piece 24 of top support cassette 25 along the outer end cutting of top support cassette 25 for the size and dimension homogeneous phase of the drum brake piece 24 that cuts production behind the control through this device is the same, and the size that cuts conveniently adjusts and controls, and this device can carry out convenient quick control regulation, makes 24 size dimensions of drum brake piece that same batch cutting process produced the same.
