Embodiment Construction

[0011] The present invention will be further described below in conjunction with the accompanying drawings.

[0012] Such as figure 1 As shown, the anti-scrap bounce-back mold applied to the punching of LED brackets, the mold includes a punch 1 and a die 2 adapted to the punch 1, and the opposite side wall of the punch 2 is provided with a recessed And the groove 3 inclined to the center line of the side wall. The opposite side wall of the die is also provided with a groove concave inward and inclined to the center line of the side wall, and the inclination direction of the groove is opposite to the inclination direction of the groove on the opposite side. The two grooves extend downward and gradually approach the center line. The depth of the groove is about 0.001 mm to 0.01 mm. The inclination of the groove is about 3 degrees with the central line, and the angle is not too large, which will generate a relatively large frictional force.

Abstract

The invention discloses a scrap bounce prevention mold applied to the punching of light-emitting diode (LED) bracket. The mold comprises a convex mold (1) and a concave mold (2) matched with the convex mold (1), wherein a groove (3) which is recessed into the side wall inwards and is inclined to the central line of the side wall is formed in a side wall on one side of the concave mold (2); a groove which is recessed into the side wall inwards and is inclined to the central line of the side wall is formed in a side wall opposite to the formed groove; and the inclined direction of the groove is opposite to the inclined direction of the groove in the opposite surface. The scrap bounce prevention mold has the beneficial effects of being easy to operate, low in cost, wide in application range and good in scrap bounce prevention effect; as long as the scrap bounce prevention concave mold is arranged in the mold, the function can be realized, retreatment after grinding is not required, a vacuum pump and a scrap collecting device are not required to be mounted, the production cost is reduced, and the labor efficiency is improved.

Description

technical field [0001] The invention relates to an LED bracket punching die, in particular to a concave die of the LED bracket punching die. Background technique [0002] In the high-speed punching die of the LED bracket, due to the fast punching speed (up to 350 times per minute), the material is thin (the thinnest reaches 0.1mm), and the binding force between the punched waste and the die is small, In the high-speed punching process, it is easy to cause the waste material to bounce back. Due to the thinness of the material, the bounced waste is difficult to be detected by the sensor, and it is easy to cause defective products and damage the die edge. [0003] The main reasons for the rebound of waste are the adsorption generated by vacuum, the adsorption to the cutting edge of the punch, the adsorption generated by oil, the magnetic force of the punch, the negative pressure caused by the compressed air of the die, etc. In addition, in the general blanking gap, the size o...
