Description

Servo compound processing machine with both stamping and forging functions

This creation is about a punching and forging mechanism, especially a servo compound processing machine that combines stamping and forging functions.

The conventional crank mechanism type punching and forging mechanism includes two types of punching machines and forging machines, and the motion curves of the moving mechanisms are mainly designed according to specific purposes such as stamping or forging. Although the press machine can provide specific machining functions such as stamping or forging, it can only provide a single function such as stamping or forging because of the poor motion curve characteristics of the crank mechanism.

In order to overcome the single function of the traditional curved mechanism forging and forging mechanism, some people have further developed and created a multi-bar mechanism punching machine or forging machine, which mainly uses the combination of the size of the rod to achieve the combination of stamping or forging. Features. However, the multi-bar mechanism hydraulic press or forging machine has the versatility of providing both stamping and forging. However, the multi-rod mechanism must be made into a synthetic change in the mechanism in response to different functions such as different stamping and forging, due to the multi-rod mechanism. The related components involve a wide range of changes, making it difficult to create synthetic changes in the organization.

In addition, some people have used the creation of equipment such as servo presses or electronic cams to make them have different functions such as stamping or forging. However, the servo motor used in the above-mentioned servo press or electronic cam and other punching and forging mechanism must select the corresponding horsepower component according to the size of the output power. Most of them use servo motors with smaller horsepower, while large powers require relatively large horsepower servo motors, and the cost of equipment is high.

The main purpose of this creation is to provide a servo compound processing machine with both stamping and forging functions such as shearing, bending, forging and extension. It is intended to solve the single function of the existing punching machine, and the direct servo drive requires more power and more. The problem that the size of the rod mechanism is difficult to synthesize and the like is achieved. The servo multi-tasking machine which has both stamping and forging functions proposed by the present invention comprises: a base; a servo drive device, which comprises a controlled a servo motor of the external controller, the servo motor is coupled with a speed reducer unit to a power input shaft, and the power input shaft is pivoted in the base; a punching and shearing curve cam mechanism includes a punching power transmission shaft and a punching curve a cam device, the punching power transmission shaft is pivoted in the base and parallel to the power input shaft, the punching curve cam device is connected between the power input shaft and the punching power transmission shaft; and a punching and bending curve cam mechanism comprises a A forging power transmission shaft and a punching and forging curve cam device, the forging power transmission shaft is pivoted in the base and parallel to the power input shaft, and is forged The line cam device is coupled between the power input shaft and the shear power transmission shaft; a clutch transmission mechanism including a wheel train, a punch clutch, a punch clutch and a direct drive clutch, the wheel train The utility model comprises a first driven shaft, a second driven shaft and a transmission output shaft And the transmission wheel set, the first driven shaft, the second driven shaft and the transmission output shaft are pivoted on the base, the transmission output shaft corresponds to the power input shaft, and the transmission wheel set is connected to the first driven shaft and the second slave The transmission shaft and the transmission output shaft are driven between the first driven shaft and the punching power transmission shaft, and the forging clutch is connected between the second driven shaft and the forging power transmission shaft to directly drive the clutch connection. Between the transmission output shaft and the power input shaft, and the shear clutch, the forging clutch and the direct drive clutch are controlled by the external controller, and any one of the clutches is switched to the interlocking state, and the other two clutches are switched to the non-coupling State; and a punching and forging mechanism, with its forging drive shaft combined with the transmission output shaft.

It can be seen from the technical features of the prior servo multi-function processing machine that it mainly uses two sets of cam mechanisms each having a punching curve and a forging curve and a direct drive, and is coupled with a clutch drive mechanism having three sets of clutches to be connected to the servo drive device. Between the driving power input shaft and the punching and forging mechanism, it can select the cam mechanism with a specific numerical curve or direct drive according to the work required, and use the servo motor to change the input speed of the punching point to adjust Stamping and forging die movement curve, to achieve a combination of cutting, bending, forging, drawing and many other functions, and the existing press can be used in this creation Or the forging machine machine as a punching and forging mechanism, the cam mechanism, the clutching transmission mechanism and the servo motor are used to complete the function of the existing forging machine to overcome the direct servo drive power limitation, and the existing crank mechanism punching machine or forging machine, Its motion curve has a single function for poor stamping characteristics and multi-bar mechanism punching or forging machine parts, and overcomes multi-rod mechanism Problems such as the difficulty in synthesizing the dimensions of the members.

Furthermore, the creation of a servo multi-tasking machine with both stamping and forging functions has the following advantages:

1. The servo multi-function processing machine can change the press timing by controlling the speed change of the servo motor in response to the requirements of cutting, bending, forging, extension, etc., and the servo motor can be obtained by the cam mechanism with numerical multi-function curve. By changing the input speed range, the power required by the servo motor is reduced, and the ability to drive the large power forging mechanism can be generated, and the performance of one machine multi-power and large power can be achieved.

2. The creative system makes the asymmetric movement of the input shaft of the punching and forging mechanism through the cam mechanism, and achieves the die movement curve of the stamping property of the stamping speed and the rapid pressing back of the die and the forging property with a long pause. Overcoming the complexity and difficulty of the path planning of the linkage mechanism, the motion characteristics of the quick-pressing and quick-returning of the punching and forging mechanism are matched.

3. This creation department uses two sets of cam mechanisms with different numerical curves to achieve the die movement curve and direct drive modes of stamping and forging, and uses three sets of clutches in the clutch transmission mechanism to change the cams with different requirements for stamping and forging. The organization is linked to the rushing and forging agency.

4. This creation can use the servo motor to change the input speed of the punching point to finely adjust the die motion curve of stamping and forging, which can effectively improve the driving power, make the servo compound processing machine more widely functioning, and achieve the performance of one machine. .

Speed and rotation position, or install the connection in the forging mechanism The linear encoder of the controller is used to measure the linear moving distance of the upper mold base to ensure the process cycle and positioning, so that the servo compound processing machine functions more widely to meet the needs of different processing operations.

In the way, a small amount of speed change is made at the stamping or forging point by the servo motor, so that the movement stroke is changed by a small amount, that is, the punching and shearing process is changed to a bending process by a small amount, and the forging process is changed by a small amount to reach a longer stroke extension.
