TECHNICAL FIELD

[0001] The utility model belongs to easy -open cover production equipment technical field, concretely relates to a kind of SOT beverage cover two-dimensional code pull ring 90 ° forming die. BACKGROUND

[0002] SOT beverage cover is a kind of piece type beverage cover, as shown in Figure, finger end is lifted to the upper pull ring, and eagle beak end can be pressed to break the line, open the preset tongue piece part, the maximum special-shaped hole of pull ring is handle hole, half moon is force reduction line hole, and the front end round hole is rivet hole;Two-dimensional code pull ring is not punched handle hole, and two-dimensional code is sprayed on the handle hole position of the reverse of pull ring. Figure 3

[0003] Normal SOT beverage cover pull ring is formed at 90 °, first, 90 ° upper mould core guide end enters handle hole pre-hole to guide pull ring blank to enter positioning, this upper mould core plays the role of guiding, positioning and forming, and can form qualified pull ring product.

[0004] Two-dimensional code SOT pull ring product cancels handle hole structure, and when being formed at 90 °, due to the lack of positioning of handle hole positioning core, pull ring is displaced under the action of different size and direction forming stretching force, the material amount of the formation of the structure of pull ring changes, causes the poor edge curling effect of subsequent process, and the problem of subsequent process is caused frequently;Pull ring edge curling effect is poor, and it also causes that pull ring strength is weakened or pull ring strength is easily exhausted, product quality is affected, and it needs to be adjusted frequently, so that the operation efficiency of equipment is low. UTILITY MODEL CONTENTS

[0005] The utility model aims at providing a kind of SOT beverage cover two-dimensional code pull ring 90 ° forming die, solve the disorder and quality problem of two-dimensional code pull ring 90 ° forming without handle hole positioning in prior art, improve the stable operation efficiency of equipment.

[0006] To achieve the above technical purpose, the technical scheme of the utility model is as follows:

[0007] A kind of SOT beverage cover two-dimensional code pull ring 90 ° forming die, including upper die and lower die, upper die is provided with upper die sleeve and upper die stripping core, the upper die stripping core is slidably arranged in the upper die sleeve, the lower die is provided with lower die sleeve, and the lower die sleeve is provided with lower die stripping core;The side of the upper die stripping core close to lower die is provided with the guide member that can pass through rivet hole, and the lower die stripping core is provided with the accommodation hole matched with the guide member.

[0008] ​Further, the guide member is conical, and the diameter of the guide member gradually decreases from the upper die stripper core to the end. In the technical solution, the guide member is conical, which is more convenient for guiding the two-dimensional code pull ring, and even if the two-dimensional code pull ring deviates greatly, the two-dimensional code pull ring can be successfully guided.

[0009] Further, when the guide member is fully inserted into the rivet hole, the outer wall of the guide member near the upper die stripper core is in clearance fit with the inner wall of the rivet hole. In the technical solution, when the guide member is inserted into the rivet hole of the pull ring, a certain gap is formed between the guide member and the rivet hole, so that the pull ring is not clamped on the guide member, and the pull ring is conveniently stripped; and the gap between the guide member and the rivet hole is not too large, and the guide member can also play a limiting role.

[0010] Further, the guide member is detachably connected with the upper die stripper core. When the two-dimensional code SOT pull ring is not needed to be produced, the guide member can be detached.

[0011] Further, the upper die stripper core is detachably provided with an upper die core which can pass through the handle hole, the lower die is provided with an upper die core sleeve, and the upper die core and the upper die core sleeve are matched.

[0012] Further, the upper die stripper core is provided with an upper die spring on the side away from the lower die stripper core, the lower die stripper core is provided with a lower die spring on the side away from the upper die stripper core, and the elastic force of the upper die spring is greater than that of the lower die spring. In the technical solution, the elastic force of the upper die spring is stronger than that of the lower die spring, the upper die stripper core presses and forms the positioned pull ring blank, when going up, the lower die stripper core and the stripper plate lift the 90-degree two-dimensional code pull ring away from the lower die by 90 degrees until the limiting position, the upper die stripper core starts to separate from the 90-degree two-dimensional code pull ring, the guide member also separates from the rivet hole, and the upper die returns to the upper die point.

[0013] The utility model adopting the above technical scheme has the following advantages:

[0014] 1. The utility model discloses a conical guide member combined with the upper die stripper core, which guides and positions the two-dimensional code pull ring first, and then presses the material, solves the problem that the guide part cannot be increased in the small space, and the guide member can be automatically stripped under the condition of meeting the positioning requirement, and the stable operation efficiency of the equipment is improved.

[0015] 2. The guide member in the utility model can not only guide the two-dimensional code pull ring, but also limit the two-dimensional code pull ring.

[0016] 3, The elastic force of the upper die spring is stronger than that of the lower die spring, the upper die stripping core presses the positioning pull ring blank into shape, when going up, the lower die stripping core and the stripping plate are lifted up by 90°, the 90° QR pull ring is separated from the lower die, until the limiting position, the upper die stripping core starts to separate from the 90° QR pull ring, the guide piece also separates from the rivet hole, and the upper die returns to the upper position.
