JPH0593625U - Turret punch press dent prevention sheet for dies - Google Patents

Abstract

(57) [Summary] [Purpose] In the case of turret punch press processing, it is easy to obtain a buffer sheet for the die and the press product in order to reduce dents on the product by punching dust and debris together. And a dent prevention sheet for a turret punch press die having improved durability. [Structure] An adhesive is applied to one surface of the chemical paper (1), and the adhesive surface protective paper (2) is attached to that surface. On the opposite side of the adhesive side of the chemical paper (1), a sheet is formed by laminating a film (3) on which oil, dust, burrs and the like such as tetron film hardly adhere. The sheet is die-cut in the shape of a mold with a stud (4).

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a sheet for sticking to the lower surface of a turret punch press die on the punch side to prevent dents on the product during press working.

[0002]

[Prior Art]

 In the past, a commercially available packaging tape was attached to the lower surface of the punch side of the turret punch press die, and it was cut with a knife to match the shape of the die to prevent dents during press working.

[0003]

[Problems to be solved by the device]

 The above method has the following drawbacks. (B) Since punching is performed under the condition that the oil adhered to the product material and the oil adhered to the mold are punched, the conventional tape is weak and easily cuts and the adhesive is exposed on the surface. The effect of not adhering to will be lost in a short period of time, and dents will be attached. (B) Since it cuts into pieces when it contains oil, it is difficult to peel off when re-attaching and it is not easy to remove the adhesive. (C) It is difficult to cut because it is difficult to cut because it attaches a large amount on the bottom surface of the mold and then cuts unnecessary parts along the edge of the mold with a knife. The present invention has been made to eliminate these drawbacks.

[0004]

[Means for Solving the Problems]

 Apply the adhesive to one side of the chemical paper and stick the adhesive side protective paper on that side. On the opposite side, a film with low coefficient of friction and high tensile strength, such as Tetoron film, is laminated. The sheet is made in this way. Die this sheet into the required shape. By peeling off the adhesive protective paper of this die-cut sheet and sticking it to the bottom surface shape of the mold, it is possible to easily obtain the bottom surface of the mold without dents, overcoming the conventional defects. I can.

[0005]

[Action]

 (B) If chemical paper is used, it is strong against oil and has moderate elasticity to absorb the pressure of debris and dust that make a dent. Strong tensile strength and hard to break. (B) Since it is not attacked by oil, there is little dust and burrs on the surface. (C) Since it is die-cut, a product having a required shape can be easily obtained. (D) The strength of the sheet is so high that it cannot be shredded. It can be easily peeled off when it is replaced. (E) Because it has stains, it can be easily peeled off.

[0006]

【Example】

 Hereinafter, examples of the present invention will be described. (B) Apply an adhesive to one side of the chemical paper (1), and apply an adhesive surface protective paper to that side. (B) On the opposite side of the adhesive side, attach a film to prevent the adhesion of oil and debris. (C) Attach the pit (4) and remove the die. (D) Peel off the adhesive surface protective paper and attach it to the lower surface of the punch side die, which is the product contact surface of the turret punch press die. This proposal has the above-described structure. The purpose of this proposal is to make a dent on the press product by the chemical paper of the sheet attached to the lower surface of the punch side mold of the turret punch press mold and the elasticity of the Tetoron film. Do not attach. Since it is difficult for dust and debris to adhere, it is less likely to make a dent on the product by pressing them together. It is designed to facilitate the replacement of a deteriorated sheet. Similar effects can be expected by using Japanese paper instead of chemical paper and general plastic film instead of Tetoron film.

[0007]

[Effect of the device]

 (B) The friction coefficient of the sheet attached to the lower surface of the punch die is low, so that dust and burrs are unlikely to adhere, and there are few dents on the product surface during punching. (B) Since the sheet has high tensile strength and is not attacked by oil, it can be easily peeled off when the sheet is replaced. (C) Since the sheet can be molded by die cutting, the desired shape can be easily obtained.
