Abstract
The invention provides a knockout pin mechanism for preventing a drawing die from being brought with materials, which is fixedly installed through an installation plate, and extrudes or releases a spiral spring through a steel round rod, so that the steel round rod always pushes against a plate to be contacted with the molded surface of a lower die, thereby playing the role of preventing the materials from being brought with materials, and a limit block limits the distance of the spiral spring and the steel round rod in a shell; the invention has the characteristics of simple structure, convenient manufacture and low cost; and effectively prevent the material from being taken in the return stroke of the drawing die and ensure the smooth operation of the automatic production process.
Description
Technical Field
The invention relates to the technical field of stamping dies, in particular to a knockout pin mechanism for preventing a drawing die from being brought with materials.
Background
With the rapid development of the automobile industry, the production frequency of a punching machine is accelerated, and the situation of material clamping of an upper die and a female die is easy to occur in field production aiming at plates with deeper drawing, so that the automatic production is seriously influenced.
Chinese patent document CN106345883A discloses a mechanism for preventing an upper die of an aluminum plate drawing die from being belted, which clamps and positions the aluminum plate through a movable chuck, thereby effectively preventing the upper die from being belted in a return stroke; the above patent needs to adopt the driving cylinder, thereby greatly improving the equipment cost and increasing the inconvenience of installation.
Disclosure of Invention
Aiming at the problems, the invention provides a knockout pin mechanism for preventing the strip of a drawing die, which is fixedly installed through an installation plate, and a steel round rod extrudes or releases a spiral spring, so that the steel round rod always pushes against a plate to be contacted with the molded surface of a lower die, thereby playing the role of preventing the strip, and a limit block limits the distance of the spiral spring and the steel round rod in a shell; the invention has the characteristics of simple structure, convenient manufacture and low cost; and effectively prevent the material from being taken in the return stroke of the drawing die and ensure the smooth operation of the automatic production process.
In order to solve the problems, the invention provides a knockout pin mechanism for preventing the drawing die from being carried with materials, which comprises an installation plate;
the surface middle part of mounting panel is fixed with the casing, is provided with the steel round bar in the casing, is equipped with the stopper on the bottom lateral wall of steel round bar, and the lower extreme of steel round bar is provided with coil spring, and coil spring is connected with the mounting panel surface.
The further improvement lies in that: the steel round rod at the upper end of the limiting block extends out of the shell.
The further improvement lies in that: positioning bolts are distributed on the lower surface of the mounting plate, and positioning suckers are arranged around the positioning bolts.
The further improvement lies in that: the top of the steel round rod is provided with a rubber sleeve in threaded connection.
The further improvement lies in that: the limiting block surrounds the surface of the steel round rod for a circle and is integrated with the steel round rod.
The invention has the beneficial effects that: the mounting plate is fixedly mounted through a positioning bolt on the mounting plate, and a positioning sucker is arranged for positioning; the plate on the molded surface of the lower die is contacted with the steel round rod, the steel round rod releases or extrudes the spiral spring according to the movement of the upper die, and the limiting block is arranged to ensure the path of the steel round rod and the spiral spring in the shell; the invention has the characteristics of simple structure, convenient manufacture and low cost; and effectively prevent the material from being taken in the return stroke of the drawing die and ensure the smooth operation of the automatic production process.
Drawings
Fig. 1 is an overall structural view of the present invention.
Wherein: the device comprises a mounting plate 1, a shell 2, a steel round rod 3, a limiting block 4, a spiral spring 5, a positioning bolt 6, a positioning sucker 7 and a rubber sleeve 8.
Detailed Description
For the purpose of enhancing understanding of the present invention, the present invention will be further described in detail with reference to the following examples, which are provided for illustration only and are not to be construed as limiting the scope of the present invention.
As shown in fig. 1, the embodiment provides a knockout pin mechanism for preventing a drawing die from being brought, which comprises a mounting plate 1; the surface middle part of mounting panel 1 is fixed with casing 2, is provided with steel round bar 3 in the casing 2, is equipped with stopper 4 on the bottom lateral wall of steel round bar 3, and the lower extreme of steel round bar 3 is provided with coil spring 5, and coil spring 5 is connected with mounting panel surface 1. The steel round rod 3 at the upper end of the limiting block 4 extends out of the shell 2. Positioning bolts 6 are distributed on the lower surface of the mounting plate 1, and positioning suckers 7 are arranged around the positioning bolts 6. The top of the steel round rod 3 is provided with a rubber sleeve 8 in threaded connection. The limiting block 4 surrounds the surface of the steel round rod 3 for one circle and is integrated with the steel round rod.
The implementation manner of the embodiment: fixing the mounting plate 1 on a die through a positioning bolt 6 manually, and arranging a positioning sucker 7 for adsorption and limiting; when the die is closed, the upper die moves downwards to enable the steel round rod 3 to be in contact with the molded surface of the lower die through the plate, so that the steel round rod 3 starts to extrude the spiral spring 5 until the limiting block 4 is in contact with the surface of the mounting seat; when the mold is opened, the upper mold moves upwards to enable the steel round rod 3 to be in contact with the molded surface of the lower mold through the plate, and the steel round rod 3 starts to release the extrusion force of the spiral spring 5 until the limiting block 4 is in contact with the top end surface in the shell 2; the plate is always jacked up by the steel round rod 3 to be contacted with the molded surface of the lower die, so that the function of preventing the strip is achieved; the rubber protective sleeve is arranged to ensure that the surface of the contacted plate is not damaged; the invention has the characteristics of simple structure, convenient manufacture and low cost; and effectively prevent the material from being taken in the return stroke of the drawing die and ensure the smooth operation of the automatic production process.
