Mold for stamping of thin material

Abstract

The invention discloses a mold for stamping of a thin material. The mold comprises an upper mold, a lower mold and a pulling mechanism, wherein the pulling mechanism is arranged at a discharging port of a material strap of the mold and comprises a pulling base fixed on the lower mold, the pulling base is provided with a linear track, a sliding block is arranged in the linear track in a moving way, a pulling block and a spring are fixed on the sliding block, one end of the pulling block is fixed on the sliding block through a positioning pin, the spring is arranged in a way of propping against the bottom of the other end of the pulling block, the top end of the pulling block is arranged in a hole of the thin material in a penetrating way, the pulling mechanism also comprises a stop pin, the stop pin is arranged above in front of the pulling block and is pressed through the spring so that the bottom of the stop pin is arranged in the hole of the thin material in a penetrating way, the sliding block is arranged under a punch, the upper end of the sliding block is provided with a bevel angle, and the sliding block can be pushed to move when the punch is pressed. The mold mainly has the following beneficial effects that errors in material delivery can be avoided, the production stability can be improved greatly, continuous stamping of the thin material can be stabilized, and the cost of a machine tool can be reduced greatly.

Description

technical field [0001] The invention relates to a mold for stamping thin materials, in particular to a material pulling mechanism for pulling thin materials, which belongs to the technical field of machinery. Background technique [0002] Some long materials usually need to be conveyed when stamping with a punching machine. There are two feeding mechanisms for traditional punching machines. One is to use a roller mechanism to convey materials, and the other is to use a clamp mechanism to convey materials. These two feeding mechanisms are suitable for transporting materials above 0.1mm. Mistakes are prone to occur when transporting materials below 0.1mm. Such as figure 1 As shown, on the existing punching machine, the feeder 5 is used to feed the material belt 1, and the material belt 1 moves forward continuously through the guide plate 4. Since the material is too thin, the longer the mold 3 is, the greater the probability of misfeeding. Because the feeder 5 is only at on...

Mistakes are prone to occur when transporting materials below 0.1mm

like figure 1 As shown, on the existing punching machine, the feeder 5 is used to feed the material belt 1, and the material belt 1 moves forward continuously through the guide plate 4. Since the material is too thin, the longer the mold 3 is, the greater the probability of misfeeding. Because the feeder 5 is only at one end of the mold 3, if the length of the mold is longer, once the strength of the material itself cannot bear the feeding force exerted by the feeder 5 on the belt, a section 6 of the belt will be arched

In this case, it is extremely easy to damage the mold parts
