The original equipment of the original test equipment is a 10t punch with a special mold. The profile of the lower mold is similar to that of the bottom spring arm B. The upper die presses down the bottom of the spring support arm A (shown). During the operation, the workers use the fingers to feed the springs one by one. Each time one is fed, the pedals are pressed on the pedals, and the punches are pressed down once to complete the test of a bottom spring. In this way, the finger punching punching danger zone is only 9mm (the width of a bottom spring); the workers use both hands and feet, according to the quota, every 5s to complete the feeding, pedaling, stamping test of a bottom spring, so that the spirit is highly concentrated It is very stressful and is prone to stamping injury accidents; at the same time, it has high labor intensity and low labor efficiency. In addition, because the bottom spring has no positioning during the test, the centering effect is poor, easy to bias, missed inspection, product quality is difficult to guarantee. Improving the principle and state of use of the equipment In response to the shortcomings of the above equipment, we used a 7t punch to redesign. The external gear-toothed ratchet rocker mechanism is used to drive the turntable to complete the test process of the workpiece, that is, feeding, punching and unloading. The improved organization diagram is as shown. The turntable 10 is coupled to the support disk 9 by a shaft 11 having dozens of stations thereon. When the punch slider 2 moves up and down, the swash plate 4 reciprocates accordingly, pushing the roller 3 on the connecting rod 8 to roll, thereby driving the connecting rod 8 to reciprocately swing, and the pawl 7 on the connecting rod moves the ratchet 5 to rotate through a certain angle. The turntable 10 is also rotated through the same angle to complete the feeding of the workpiece. A check pawl 6 is fixed in the direction of 90b with the pawl to prevent the ratchet from rotating in the reverse direction. During operation, the worker is away from the stamping danger zone, and the spring is simply placed in the turntable, and the workpiece is accurately fed into the machining position as the turntable rotates to perform the stamping test. If the elastic spring is good, the support arm A is pressed down, and its outer dimensions can meet the requirements of the industry standard, which is regarded as a good product; if the elastic state is poor, the support arm A is pressed down, the outer dimensions are not up to If the requirements are required or a break occurs, it is considered as a non-conforming product. The improved effect improves the product quality. The turntable is driven by the ratchet, and the workpiece is accurately positioned. Neutral 1-punch; 2-punch slider; 3-roller; 4- slant plate; 5- ratchet; ; 7-pawl; 8-link; 9-support disk; 10-turntable; 11-axis. Reduce labor intensity and prevent work-related accidents. The new test-machine operation is simple and reduces the labor intensity, so that the fingers of the operator are far away from the stamping danger zone, and the occurrence of work-related accidents is eliminated.
