As shown in fig. 1 and 2, the tablet press is provided with a vibration disc 1, a feeding manipulator assembly 2 and a tablet pressing assembly 3, the tablet pressing assembly 3 is provided with the above-mentioned depth pressing adjusting assembly 31, and the tablet pressing assembly 3 is further provided with a top pressing assembly 32, a cam 33 and a servo motor assembly 34. When the tablet press works, the vibration disc 1 sorts the bimetal 99 workpieces and then outputs the workpieces in a queue, as shown in fig. 4 and 5, the feeding manipulator assembly 2 picks up the bimetal 99 workpieces output by the vibration disc 1 to the entrance of the jig block 326, the bimetal 99 workpieces fall to the upper side of the upper baffle 41 in the extending state under the action of gravity, the lower baffle 42 in the extending state blocks the bimetal 99 workpieces to be processed, and the bimetal 99 workpieces to be processed are coaxial with the pressing rod 321. As shown in fig. 2 and 7, the pressing assembly 32 is provided with the pushing arms 322 and the pressing rods 321, the number of the pressing assemblies 32 is two, and the two sets of pressing assemblies 32 are symmetrical in front and back, so that the number of the pressing depth adjusting assemblies 31 is correspondingly two, and the pressing rod limiting blocks 313 of the front and back sets of pressing depth adjusting assemblies 31 respectively correspond to the limiting front and back pressing rods 321. The servo motor assembly 34 drives the cam 33 to rotate about the vertical axis, when the protruding end of the cam 33 collides with the left end of the push arm 322, the left end of the push arm 322 is moved outward, so that the right end of the push arm 322 moves inward (i.e., the right end of the push arm 322 moves toward the bimetal 99 workpiece), and then the right end of the push arm 322 contacts the push rod head 3212 to move toward the bimetal 99 workpiece, for example, as shown in fig. 6, the push rod 321 located at the rear position pushes the rear of the bimetal 99 workpiece forward, specifically, the push end 3211 of the inner end of the push rod 321 contacts the bimetal 99 workpiece, whereupon the protruding end of the cam 33 moves away from the push arm 322 located at the rear position, whereupon the push rod 321 is reset outward (i.e., moves away from the bimetal 99 workpiece) by the elastic restoring force of the push rod reset spring 324, and as the cam 33 rotates, the protruding end of the cam 33 pushes the pushing arm 322 located at the forward position, so that the pushing rod 321 located at the forward position moves backward to push the front of the workpiece of the bimetal 99, so that after one bimetal 99 is processed, the cam 33 drives the two groups of pushing assemblies 32, the structure is simple and stable to operate, then the lower baffle 42 retracts away from the corresponding position of the bimetal 99, so that the bimetal 99 falls off due to gravity, then the lower baffle 42 stretches out and resets, the upper baffle 41 retracts so that one bimetal 99 workpiece originally intercepted by the upper baffle 41 falls to the upper side of the lower baffle 42 and is intercepted by the lower baffle 42, then the upper baffle 41 stretches out and resets, and the feeding manipulator assembly 2 puts the next bimetal 99 workpiece at the entrance of the jig block 326, thus the bimetal 99 can be efficiently and automatically produced, as shown in fig. 7 and 8, when the pressing wheel 3221 at the right end of the push arm 322 abuts against the outer end face of the rod head 3212 of the push rod 321 and the pressing wheel 3221 pushes the rod head 3212 inward until the blocked end face 3215 of the rod head 3212 abuts against the limiting end face 3132 of the push rod limiting block 313, the push rod 321 cannot move inward any more, and at this time, the pushing force of the cam 33 on the push arm 322 is buffered by the buffer spring 3222 (see fig. 7) at the left end of the push arm 322, in other words, the limiting end face 3132 limits the amplitude of the push rod 321 pushing against the bimetal 99 workpiece. When the amplitude of the workpiece of the bimetal 99 is required to be pressed by the pressing rod 321, as shown in fig. 7 and 11, the adjusting wedge 312 is moved leftwards, the driving inclined surface 3121 extrudes the pushed inclined surface 3131 of the pressing rod limiting block 313, if the pressing rod limiting block 313 is moved outwards to adjust the position, the amplitude of the workpiece of the bimetal 99 is reduced by the pressing rod 321, if the adjusting wedge 312 is moved rightwards, the driving inclined surface 3121 gives up the space for the pushed inclined surface 3131, the pressing rod limiting block 313 can be pushed inwards to a little, so that the amplitude of the workpiece of the bimetal 99 can be increased by the pressing rod 321, and the limited force of the pressing rod limiting block 313 by the blocked end surface 3215 of the pressing rod 321 is insufficient to overcome the friction force borne by the adjusting wedge 312, thereby playing a self-locking effect and avoiding the limiting effect of the pressing rod limiting block 313 on the pressing rod 321 from being invalid due to the rightward displacement caused by the driving of the pressing wedge 321. By arranging the pressing depth adjusting structure, the amplitude of the pressing rod 321 for pressing the bimetal 99 workpiece is adjustable, so that the position of the pressing rod limiting block 313 is adjusted according to the actual material and thickness dimension of the bimetal 99 workpiece, or in other words, when the material or dimension of the bimetal 99 workpiece is changed, a worker can process and debug the bimetal 99 workpiece by changing the position of the pressing rod limiting block 313, so that the shape and dimension of the bimetal 99 finished product are in line with the requirements, and batch waste of the bimetal 99 is avoided. By arranging the top pressing rod 321 to penetrate through the top pressing rod limiting block 313 and arranging the blocking end face 3215 to be used for contacting the limiting end face 3132, blocking resultant force borne by the top pressing rod 321 is beneficial to the axis of the top pressing rod 321, namely, the top pressing rod 321 is prevented from being subjected to bending moment, and bending deformation of the top pressing rod 321 is avoided.

Further, as shown in fig. 9 to 11, the depth pressing adjusting assembly 31 includes a wedge return spring 315, an adjusting wedge 312 is disposed between the wedge return spring 315 and the micrometer head 314, specifically, a right end of the wedge return spring 315 is abutted against a left end of the adjusting wedge 312, and a driving inclined plane 3121 of the adjusting wedge 312 is set to be low left and high right, and a top pressing bar limiting block 313 is located at an outer side of the adjusting wedge 312, so that the micrometer screw of the micrometer head 314 can drive the top pressing bar limiting block 313 to move outwards, and when the micrometer screw of the micrometer head 314 moves in a direction away from the adjusting wedge 312 by rotating a screw cap of the micrometer head 314 in a reverse direction, an elastic restoring force of the wedge return spring 315 pushes the adjusting wedge 312 to move rightward so that the adjusting wedge 312 keeps abutting against the micrometer screw of the micrometer head 314, so that the adjusting wedge 312 can move left and right along with the micrometer screw of the micrometer head 314. The worker can record the readings of the corresponding micrometer heads 314 of the different kinds of the bimetal 99, and the worker can conveniently and quickly adjust the adjusting wedge 312 in place when the kinds of the workpieces of the bimetal 99 are replaced.
