Detailed Description

The first embodiment is as follows: referring to fig. 1-2, a powder forming device capable of accurately controlling the lower limit position of an upper slide block is arranged on a double-head hydraulic cylinder 01 of powder forming equipment and comprises a servo motor 1, a transmission mechanism, an adjusting stop block 3 and a limit stop block; an output rod at one end of the double-head hydraulic cylinder 01 is coaxially and fixedly connected with an upper sliding block 02; an output rod at the other end of the double-end hydraulic cylinder 01 coaxially penetrates through the adjusting stop block 3 and is coaxially connected with the limit stop block; the head end of the transmission mechanism is connected with the power of the servo motor 1; the tail end of the transmission mechanism is in threaded fit with the adjusting stop block 3; the torque of the servo motor 1 is converted into the axial movement of the adjusting stop block 3 after being transmitted by the transmission mechanism; the end face of the adjusting stop block 3 is matched with the end face of the limit stop block.

The servo motor 1 provides a power source and can output controllable torque; the corresponding servo motor 1 can also be replaced by a stepping motor; the axial movement of the adjusting stop 3 can be accurately controlled because the tail end of the transmission mechanism is matched with the thread of the adjusting stop 3; the controllable torque output by the servo motor 1 is converted into the controllable axial movement of the adjusting stop block 3, so that the servo motor 1 can output a certain torque every time and can drive the adjusting stop block 3 to move for a corresponding distance; this distance corresponds to the desired pressing thickness of the powder to be formed at each pass; the limit stop block is matched with the adjusting stop block 3 after the axial movement; the double-end hydraulic cylinder 01 is stably output, the limit stop is connected with the adjusting stop 3, and the upper slide block 02 moves by a corresponding pressing thickness each time, namely the pressing thickness of each time of powder stamping can be effectively ensured; finished products manufactured in batches by using the powder forming equipment of the powder forming equipment device capable of accurately controlling the lower limit position of the upper sliding block can obtain uniform pressing thickness, and the quality of the finished products is better; the axial movement of the adjusting stop 3 in this embodiment is vertical lifting; the distance of each lowering of the adjustment block 3 corresponds to the pressing thickness.

The end part of the adjusting block 3 is sleeved with a holding ring 5; the inner wall of the clasping ring 5 is in interference fit with the outer wall of the adjusting stop block 3; the clasping ring 5 is fixedly connected with the double-head hydraulic cylinder 01; the clamping ring 5 can clamp the adjusting stop block 3 tightly so that the adjusting stop block cannot axially rotate and only can axially move; the torque transmitted by the transmission is entirely applied to the axial displacement of the setting dog 3.

A limit sensor A61 and a limit sensor B62 are arranged on one side of the double-head hydraulic cylinder 01 along the axial direction of the double-head hydraulic cylinder 01; an induction block 63 matched with the limit sensor A61 and the limit sensor B62 is arranged between the limit sensor A61 and the limit sensor B62; the induction block 63 is fixedly connected with the adjusting stop block 3; the limit sensor A61 and the limit sensor B62 respectively correspond to two limit positions of the axial movement of the adjusting stop 3; the induction block 63 is matched with the limit sensor A61 and the limit sensor B62 respectively to indicate that the adjusting module moves to two limit positions respectively; in the prior art, when the limit sensor A61 and the limit sensor B62 are travel switches, the induction block 63 is a corresponding collision block; when the limit sensor A61 and the limit sensor B62 are photoelectric switches, the sensing block 63 is corresponding to the photosensitive film; because the alternative schemes are mature and various, the embodiments are not listed.

The limit stop comprises a stop nut A41 and a stop nut B42 which are in threaded connection with the output rod of the double-head hydraulic cylinder 01; the stop block nut shell 41 is matched with the adjusting stop block 3; the stop block nut B42 locks the stop block nut A41; the stop block nut A41 is closer to the double-head hydraulic cylinder 01 than the stop block nut B42; the reason for selecting the structures of the stop nut a 41 and the stop nut b 42 in this embodiment is that the structure is simple and a certain calibration adjustment can be performed.

There are many alternative configurations of the transmission, such as a worm gear configuration; the worm is in power connection with the servo motor 1; the worm wheel is coaxially matched with the adjusting stop block 3 in a threaded manner; the structure has the advantages that unidirectional self-locking can be realized; however, the embodiment adopts another structure; the transmission mechanism comprises a gear A21 and a gear B22 which are meshed with each other; the output end of the servo motor 1 is coaxially and fixedly connected with a gear A21; the gear B22 is in coaxial threaded fit with the adjusting stop 3; relatively speaking, the structure is simpler and more compact, and the reliability is high.

The end part of the double-head hydraulic cylinder 01 is fixedly connected with a mounting seat 7; the mounting seat 7 is provided with a transmission mechanism.

The working principle of the embodiment is that the servo motor 1 can output torque in a controllable manner; the torque is transmitted by the transmission mechanism to drive the adjusting stop block 3 to move axially; because the axial movement of the adjusting stop 3 is realized by thread fit, the axial movement distance of the adjusting stop 3 can be accurately controlled; the distance of each descending of the adjusting stop block 3 corresponds to the required pressing thickness of the powder; the adjusting stop block 3 limits the travel of the limit stop block and an output rod of the double-head hydraulic cylinder 01; therefore, the newly increased stamping distance of the upper sliding block 02 can reach the corresponding pressing thickness each time until the single finished product is manufactured; finished products manufactured in batches by using the powder forming equipment of the powder forming equipment device capable of accurately controlling the lower limit position of the upper sliding block can obtain uniform pressing thickness, and the quality of the finished products is better.
