Description

Automatic feeding device for plates in part machining process

Technical Field

The invention relates to the technical field of machinery (structures), in particular to an automatic feeding device for plates in a part machining process.

Background

The machining is a process of pursuing quality and efficiency, and in the modern machining process, the reduction of the auxiliary time in the machining has very important significance for improving the machining efficiency. Moreover, to automate production, the amount of time required for assistance must be reduced. The time consumed by feeding in the processing process belongs to auxiliary time, and the automatic feeding device is a special device designed for reducing the feeding time, realizing the production automation and improving the processing efficiency.

At present, automatic feeding is realized by partial automatic feeding devices, but the structure is complex, the effect is not obvious, and manual auxiliary operation is still needed. The device can convey the plates to the machine tool or a designated working place according to a certain sequence, reduces the labor amount of repeated operation of workers, reduces the labor intensity of operators, and has great significance for safety production.

SUMMERY OF THE UTILITY MODEL

Technical problem to be solved

Aiming at the defects of the prior art, the invention provides an automatic feeding device for plates in the part machining process. The invention simplifies a complex automatic feeding mechanism, and the complex automatic feeding mechanism is arranged on the machine tool, so that the automatic feeding step can be efficiently completed with high quality under the assistance of a small amount of manpower, the production efficiency of the machine tool is further improved, the production capacity of the machine tool is fully exerted, and semi-automatic or automatic production is realized, so as to solve the problems in the background technology.

(II) technical scheme

In order to achieve the purpose of automatic feeding, the invention provides the following technical scheme: the utility model provides an automatic feed device of panel among parts machining process, includes the support, automatic feed device installs on the support, its characterized in that: the support is rigidly connected with the workbench, the vertical lever is hinged on the support, the upper arm of the lever is connected with the punch through a spring, and a push rod is rigidly connected with the punch on the right side of the joint. The lower arm of the lever is hinged to the hook, one end of the hook is connected with the upper arm of the lever through a spring, and the other end of the hook hooks the stamping hole in the plate. The punch press moves up and down to drive the push rod to move up and down, so that the position of the hook is changed through the upper arm and the lower arm of the lever, and the automatic feeding of the plates is realized.

Preferably, the lever is vertical, the upper and lower arms are vertical to each other, and the direction of the force is changed by a spring.

Preferably, the hook converts the up-and-down reciprocating motion of the punch press into horizontal motion of the driving plate through a lever.

Preferably, the hook hooks the punching hole to drive the plate to move.

(III) advantageous effects

Compared with the prior art, the invention provides the automatic feeding device for the plate in the part machining process. The method has the following beneficial effects:

1. this automatic feed device through original punch press up-and-down motion as power, has eliminated external power supply, has reduced the complexity of mechanism.

2. The automatic feeding device adopts the vertical lever, and can effectively and timely change the direction of the acting force under the action of the spring. In addition, the springs with different rigidity are selected, so that the device can adapt to different punch press movement rates. The device has simple mechanism and convenient disassembly and assembly.

Drawings

FIG. 1 is a schematic structural view of the present invention;

in the figure: 1 support, 2 workstations, 3 levers, 4 hooks, 5 springs, 6 punches, 7 push rods, 8 springs, 9 punching holes, 10 plates, 11 punches and 12 dies.

Detailed Description

As shown in fig. 1, the present invention provides a technical solution: the utility model provides an automatic feed device of panel in parts machining process, includes support 1, and support 1 installs on workstation 2. One end of the vertical lever 3 is hinged with the hook 4, and the other end is connected with the punch 6 through the spring 5. A push rod 7 is arranged at the right side of the connection part of the punch 6 and the spring 5. The up-and-down reciprocating motion of the punch 6 drives the push rod 7 to reciprocate up and down, thereby pushing the lever 3 to move. One end of a hook 4 hinged with the lever 3 is connected with the upper arm of the lever through a spring 8, and the other end of the hook 4 hooks a stamping hole 9. The movement of the hook 4 drives the plate 10 to move on the horizontal plane of the workbench 2, so as to achieve the purpose of feeding.

The working principle is as follows: when the device is used, firstly, a worker places a plate material at the right position of a die to punch. After a plurality of working strokes, the hook enters a punching hole formed after the punch drives the punch to punch the plate. At this point automatic feeding is started. When the punch moves upwards, the lever rotates clockwise by a certain angle under the action of the spring to drive the hook hinged with the lever to move leftwards, and the plate is pulled to move leftwards by a feeding stroke to prepare for next punching. When the punch moves downwards for punching, the push rod pushes the lever to rotate anticlockwise for a certain angle, the hook hinged with the lever moves rightwards to enter a punching hole formed in the previous working stroke, and feeding action of the next stroke is prepared. In conclusion, automatic feeding is completed in this way.

Having thus shown and described embodiments of the present invention, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
