Metal sheet bending test machine

This creation is about a physical inspection tool for metal foil, especially a metal sheet bending test machine.

In the physical property testing project of metal foil, the bending test is one of them. At present, when the operator performs the bending test of the metal foil, the test is mainly carried out using a set of manual metal sheet bending testers. As shown in FIG. 9, the manual metal sheet bending test machine is provided with a manual bending device 60 on a working platform 50. The manual bending device 60 includes a lower holder 61 and an upper holder 62. , a rocker arm 63 and a pre-tensioning device 64 are mounted on the base 50. The rocker arm 63 is pivotally mounted on the working platform 50 with the lower end of the arm 631. The rocker arm 63 The upper end of the arm 631 is combined with the pre-tensioning device 64 to connect the holder 62 so that the upper holder 62 and the lower holder 61 are vertically opposed to each other. The hand arm 63 is provided with a handle 632 at the upper portion of the arm 631. A lower portion of the arm 631 is provided with a clamping block 633 above the lower holder 61.

When the bending test of the metal test piece is performed by using the manual metal sheet bending tester, one end of the metal test piece 40 is first fixed in the upper holder 62, and then the pre-tensioning device 64 is manually pressed, and the metal test piece is pressed. The other end of the 40 is fixed by the clamp 633 on the arm 631 of the hand arm 63 and protrudes into the lower holder 61, and then releases the pre-tensioning actuator 64, which is passed through the upper clamp by the restoring force of the pre-tensioning device 64. The holder 62 applies a predetermined force to the metal test piece 40 to tension the metal test piece 40. Next, the operator holds the handle 532 of the hand arm 63 to reversely bend the metal test piece 40 180 degrees backward, and manually counts the number of times of bending until the metal test piece 40 is broken, and records the number of times of bending.

However, the manual metal sheet bending test machine provides a tool for the operator to apply the bending test of the metal sheet. However, when the operator operates the manual sheet metal bending test machine, It is necessary to hold the hand arm in the reverse direction to bend the metal test piece many times until the metal test piece is broken, and it is laborious to operate, and the operator repeatedly bends the metal test piece manually for a long time, which is easy to exert instability and hand pain. Waiting for something.

Furthermore, when manually bending the rocker arm to bend the metal test piece to perform the bending test, the number of bending times must be manually counted, and the number of bending of the wrong metal test piece is likely to occur during manual counting, which affects the bending of the metal piece. The accuracy of the test.

The main purpose of this creation is to provide a metal sheet bending test machine, which is designed to solve the problem that the existing manual metal sheet bending test machine is laborious and the hand of the operation is easy to be painful.

In order to achieve the foregoing, the metal sheet bending test machine proposed by the present invention comprises: a base; a bending device comprising a lower holder, an upper holder, a rocker arm and a pretensioning function. The lower gripper is disposed on the base, and the lower end of the rocker arm is pivotally mounted on the base, and the upper end of the rocker arm is coupled with the pre-tensioning device group to connect the gripper, so that the upper gripper and the lower gripper are upper and lower. And a driving device is mounted on the base, the driving device comprises a servo motor, a servo driver and a connecting rod, the servo driver is electrically connected to the servo motor, and the two ends of the connecting rod are respectively connected with the spindle of the servo motor With the upper section of the rocker arm.

It was created by the front metal strip bending test machine, which mainly uses the servo motor of a driving device to connect the upper part of the rocker arm of the bending device with the connecting rod, and automatically drives the rocker arm to repeatedly bend the metal test piece for bending test. It is more labor-saving for the operator to carry out the bending test of the metal test piece, overcome the laborious operation of the bending test of the existing manual metal test piece, and the problem of easy hand pain of manually bending the metal test piece. Furthermore, the present invention automatically drives the rocker arm to repeatedly bend the metal test piece to perform a bending test, thereby ensuring the stability of the bending force applied to the metal test piece.

The metal sheet bending test machine of the present invention may further include a control panel having a control component and a display, and a rotary encoder. The control panel is electrically connected to the servo driver, and the rotary encoder is disposed inside the servo motor. The rotary encoder is electrically connected to the control panel for automatically counting the number of times the rocker bends the metal test piece, and the display shows the number of bends, thereby avoiding the manual counting of the number of bends of the metal test piece.

The metal sheet bending tester of the present invention can further add a toggle clamp on the base for combining the metal test pieces between the upper and lower clamps of the bending device by means of a toggle clamp. The pre-tensioning device allows the operator to apply a force to the metal test piece mounted between the upper and lower holders in a labor-saving and simple operation mode, so that the metal test piece maintains the proper flatness in the bending test. .
