(2) The utility model discloses can replace artifical centering through tongs automatic centering, improve the quality of punching a hole, reduce part wall thickness difference, can reduce the use of buggy simultaneously, have very big improvement to the environment.
Drawings
FIG. 1 is a schematic view of the structure of the middle gripper of the present invention;
fig. 2 is a side view of the centering base of the present invention.
The components in the drawings are numbered as follows: 1-centering base, 11-mounting seat, 12-hydraulic cylinder telescopic rod, 2-clamping finger, 3-clamping finger mounting unit and 4-grabbing tooth tightening driving device.
Detailed description of the preferred embodiments
The technical solution protected by the present invention will be specifically described below with reference to the accompanying drawings.
Referring to fig. 1 and 2, the utility model provides an automatic centering mechanical tongs for improving punching quality, including centering base 1 and tongs module, be provided with tongs module drive arrangement in the centering base 1. The gripper module comprises a mounting seat 11, a left gripper module and a right gripper module, each gripper module comprises a clamping finger 2 and a clamping finger mounting unit 3, each clamping finger mounting unit 3 comprises an upper mounting support and a lower mounting support, each clamping finger 2 is mounted at the end part between the upper mounting support and the lower mounting support, and the clamping fingers 2 and the clamping finger mounting units 3 are integrally formed or can be in a detachable mounting structure. The profiling surface of the clamping finger 2 is an arc surface, and the radian of the arc surface is consistent with that of the outer wall surface of the punching barrel. The gripper module further comprises a gripper tooth tightening driving device 4, and the gripper tooth tightening driving device 4 drives the gripper module to clamp the punching barrel.
In one embodiment, the gripper module driving device is a hydraulic cylinder, and the mounting base 11 is connected to the gripper module driving device through a hydraulic cylinder telescopic rod 12, so that the gripper module is mounted on the centering base 1.
The working principle is as follows: the automatic punching device is characterized in that a punch clamping block is mounted on a swing arm manipulator, a punch and a material baffle are mounted in the punch clamping block, a punching driving device is arranged in the punch clamping block and is a hydraulic cylinder, a hydraulic rod of the hydraulic cylinder is connected with the material baffle, and whether the punch is flatly placed or not is visually checked by a worker. And then operating the press to move upwards to the highest position, then idling the swing arm to the punching position, operating the press to move downwards, then controlling the press to move upwards to the highest position again, and finally rotating out the swing arm. This series of operating stations is a preparation before punching, mainly to check whether the installation of the device is complete and it is possible to operate it.
The operation is started after the heat preservation time of the device is up, because the placing position of the punching barrel is scribed on the lower table top of the press, an operator can roughly place the punching barrel in the determined placing position range, the mounting position of the centering base 1 and the central position of the lower table top of the press are positioned on the same straight line, a heated bar is placed into the punching barrel by a forklift, the press descends to thicken the bar at the moment, the press ascends to the highest position after the thickening is completed, then the gripper module driving device in the centering base 1 drives the gripper module to advance, after the gripper module grips the punching barrel, the gripper tooth tightening driving device 4 drives the clamping finger mounting unit 3 and the clamping fingers 2 to clamp the punching barrel, the idler wheels at the front end and the rear end of the clamping fingers 2 enable the gripper teeth to be positioned in the profiling surface of the clamping fingers 2 in the tightening process, the gripper module driving device drives the gripper module, and the telescopic length of the hydraulic cylinder 12 is adjusted to ensure that the punching barrel is positioned in the central position of the lower table top of the press. And then, when the swing arm rotates to the punching position, the press descends again to punch the bar.
In one embodiment, the gripping tooth tightening drive 4 is a hydraulic cylinder, which forms a hydromechanical gripper with the clamping finger mounting unit 3.
After punching is finished, the upper table top of the press rises by 5mm, then the demolding hydraulic cylinder in the punch clamping block is started to perform demolding, the press is lifted to the highest position again after demolding is successful, then the swing arm is rotated out to the initial position, the ejection block forklift is placed to cooperate with demolding, finally the part is reversed and trimming is performed according to the existing mode, and then punching is finished. The utility model discloses a tongs automatic centering replaces artifical centering, improves the quality of punching a hole, reduces part wall thickness difference, can reduce the use of buggy during the drawing of patterns simultaneously, has very big improvement to the environment.
The above only is the embodiment of the present invention, not limiting the patent scope of the present invention, all the equivalent structures or equivalent processes that are used in the specification and the attached drawings or directly or indirectly applied to other related technical fields are included in the patent protection scope of the present invention.
