Definitions
- the present invention relates to an upper die for attaching a button, and more particularly to an upper die for attaching a button used when attaching a snap button or a decorative button to a cloth using a button attaching member.
- an upper mold is generally used.
- the upper die is fixed to a lifting portion of a button mounting press device, and has a cylindrical punch portion for caulking a post portion of the button mounting member.
- a mold body caulking punch
- a center hole through which the punch passes a button holder (guide punch) that holds the button when the button is attached, and a cylindrical shape provided between the mold body and the button holder And an elastic body.
- the button mounting member When attaching the button to the fabric, hold the button on the button holder of the upper mold, place the button mounting member on the lower mold, and further arrange the fabric horizontally between the button and the button mounting member, Operate the button mounting press to lower the upper die. Due to the lowering of the upper mold, the post part of the button mounting member penetrates the cloth upward, and after passing through the button mounting opening, the punch part of the mold main body caulks the post part. At the time of this caulking, the button holding body presses the button against the cloth, and the cloth is compressed between the button and the button mounting member on the lower mold.
- the above elastic body is deformed by receiving a load in the axial direction from the mold body and the button holding body to remove the cloth through which the post part penetrates the cloth, and at the time of caulking to press the button against the cloth and tighten the post part.
- the material is deformed more greatly than the time of unloading, thereby absorbing and mitigating the load on the button, upper die, button mounting press device and the like during unloading and caulking.
- the elastic body in the conventional upper mold has a single flexibility (spring property) in which the amount of deformation increases almost in proportion to the axial load, the load at the time of removing the fabric and the caulking time When both of these loads are applied, the elastic body deforms more than necessary during caulking to allow an excessive load, so that a large load is applied to the button, the upper die, the button mounting press device, and the like.
- the flexibility of the elastic body is changed so as to reduce the load on the button, upper die, etc. during caulking, the post part will be buckled when the dough is removed, etc. There is a problem that it is not performed.
- the present invention has been made in view of the above-described problems, and its purpose is to bear both the load that the elastic body receives during dough removal and the load that it receives during caulking, and the button,
- An object of the present invention is to provide an upper die for attaching a button capable of reducing the load applied to an upper die, a button attaching press device and the like.
- a button including a woven fabric, felt, non-woven fabric, leather, resin sheet, etc.
- a button mounting member having a post portion when attaching a button (including a woven fabric, felt, non-woven fabric, leather, resin sheet, etc.) to a button having a mounting opening using a button mounting member having a post portion.
- An upper mold for attaching a button for penetrating a cloth and then caulking a post portion that passes through an opening for attaching a button, and an upper elastic body that receives a cylindrical elastic body and an upper surface in an axial direction of the elastic body A body body having a cylindrical punch portion for caulking the post portion of the body receiving portion and the button mounting member, a lower elastic body receiving portion receiving the lower surface in the axial direction of the elastic body, and a center through which the punch portion passes
- An upper die for attaching a button having a thin portion that is thin in the radial direction by the concave portion on the radially outer side of the concave portion and a plurality of thick portions that are thicker than the thin portion in the axial direction of the concave portion and the thin portion.
- the elastic body corresponds to the radially outer side of the concave portion by providing an annular concave portion that is recessed radially outward from the inner peripheral surface at the axial center of the inner peripheral surface of the cylindrical elastic body. It is divided into a thin portion that is a portion and a plurality of thick portions that are portions left and right in the axial direction of the concave portion and the thin portion.
- the elastic body is once displaced in the restoring direction and a part of the load is released, and then a larger load is applied to the elastic body during caulking than when the fabric is removed.
- the thin-walled portion deforms greatly beyond the amount of deformation when the dough is removed, and then the plurality of thick-walled portions start to deform substantially after contacting or approaching each other to absorb the load. Therefore, the flexibility of the elastic body can be made different between when the dough is removed and when caulking.
- Examples of the material of the elastic body include synthetic rubbers such as polybutadiene, nitrile, and chloroprene, natural rubber, and the like, and urethane rubber and the like can be preferably used.
- the above “axial middle” means between the upper end and the lower end in the axial direction of the elastic body.
- the thin portion when the post portion penetrates the dough, the thin portion deforms exclusively, and when the post portion is crimped, the thin portion first deforms beyond the deformation amount when the dough penetrates. Then, the thick part is deformed. Thereby, it can respond by changing the flexibility of an elastic body at the time of dough removal and caulking.
- the elastic body when the post portion is caulked, the axial gap of the concave portion is reduced, and the thick portions adjacent in the axial direction approach each other. That is, the elastic body is deformed by the axial load at the time of caulking, the concave portion is crushed, and the upper and lower thick portions of the concave portion are close to or in contact with each other. After the thick portions approach each other, the amount of deformation of the elastic body with increasing load decreases.
- the elastic body has a first flexibility in which a thin-walled portion is deformed when the post portion penetrates through the fabric, and a second flexibility in which a thick-walled portion is deformed when the post portion is caulked.
- the elastic body exhibits a first flexibility in which a thin-walled portion that is easy to deform is deformed exclusively when the dough is subjected to a relatively small load, and the thin-walled portion is substantially deformed when caulking that is applied with a larger load than when the dough is removed.
- the thick part that is hard to be deformed as compared with the thin part is deformed (different from the first flexibility), and the second flexibility is exhibited. Therefore, the elastic body does not deform excessively during caulking, unlike the elastic body in the conventional button mounting upper mold. Desirable first and second flexibility can be set by changing the shape, number, and the like of the recesses of the elastic body.
- the thin portion extends radially outward from the thick portion when the button is attached to the cloth. That is, the thin-walled portion is elastically deformed so as to expand outward in the radial direction from the thick-walled portion when the button is attached to the fabric. Becomes larger.
- the elastic body has a plurality of the concave portions in the axial direction.
- one concave portion can be provided at a position that is 1/3 of the axial length from the upper end of the elastic body, and the other concave portion can be provided at a position that is 1/3 from the lower end. It becomes the following three. Three or more recesses can be provided.
- the thick part and the thin part are formed of different materials.
- the selection and combination of the material of the thick and thin parts is more appropriate. Can be set.
- the elastic body is provided with a concave portion, and the elastic body is divided into a thin wall portion and a thick wall portion, and the thin wall portion is deformed when removing the fabric with a relatively small load on the elastic body.
- the caulking is applied with a larger load, the thin-walled portion is deformed more than when the dough is removed, and then the thick-walled portion is deformed to absorb the load. Therefore, it is possible to effectively cope with different flexibility of the elastic body both when removing the fabric and when caulking, and since the elastic body does not deform too much when caulking, the load applied to the elastic body becomes small, The load on the button, upper die, button mounting press device, etc. is reduced.
