Problems solved by technology

[0003] Most of the existing car key cases are made by stitching the front and back sides of the key case, and the cavity between the front and back sides is used as a space for placing car keys. However, the overall structure of this car key case is relatively flat and flexible. Poor, the car key is often difficult to put in and take out. After long-term use, it is very easy to break the line, crack the skin, etc., which is not practical and affects the appearance of the product

Embodiment 1

[0037] A three-dimensional stereotyped car key case manufacturing process, including the following steps:

[0038] Step 1: Half panel production;

[0039] Wrap the entire car key with masking paper, and cut the wrapped masking paper at the center line of both sides of the key to make a symmetrical front half panel and back half panel, and place them on the front according to the lines on the front and back of the car key. Drawing copper mould embossing lines on half panel and back half panel;

[0040] Step 2: Punching the leather case;

[0041] According to the outline dimensions of the front half panel and the back half panel prepared in step 1, a cold die is produced, and the key cover A side 1 and the key cover B side 2 are prepared by punching the raw materials through the cold die; the key cover A side and the key cover B side An opening point 3 is also provided, and the horizontal linear distance between the opening point and the highest point of the width of the key cover A su...

Embodiment 2

[0054] Step 1: Half panel production;

[0055] Wrap the entire car key with masking paper, and cut the wrapped masking paper at the center line of both sides of the key to make a symmetrical front half panel and back half panel, and place them on the front according to the lines on the front and back of the car key. Drawing copper mould embossing lines on half panel and back half panel;

[0056] Step 2: Punching the leather case;

[0057] According to the outline dimensions of the front half panel and the back half panel prepared in step 1, a cold die is produced, and the key cover A side and the key cover B side are produced by punching the raw materials through the cold die; the key cover A side and the key cover B side are also set There is an opening point, and the horizontal straight line distance between the opening point and the highest point of the width of the key cover A surface and the key cover B surface is greater than 10mm. In this way, when the key is inserted into t...

Abstract

The invention discloses a manufacturing process of a three-dimensional shaped automobile key case. The manufacturing process comprises the following steps: step 1, manufacturing a semi-panel; wrappinga whole automobile key with a masking tape, cutting off the wrapped masking tape at the center line positions of the two sides of the key to manufacture a front half panel and a back half panel whichare symmetrical, and drawing copper die pressing lines on the front half panel and the back half panel according to the lines on the front face and the back face of the automobile key respectively; step 2, punching the leather sheath; making a cold stamping die according to the overall dimensions of the front half panel and the back half panel manufactured in the first step, and making a key sleeve face A and a key sleeve face B by blanking raw materials through the cold stamping die; the invention has the advantages that even if no filler exists in the key sleeve, the three-dimensional shapematched with an automobile key can be kept, and the automobile key can be better attached to the key sleeve.

Description

Technical field [0001] The invention relates to a process for manufacturing a three-dimensional stereotyped automobile key case. Background technique [0002] The car key case is mainly used to protect the appearance of the car key, and at the same time, it can also make the car key more high-end and more beautiful. [0003] Most of the existing car key cases are stitched on the front and back sides of the key case. The cavity between the front and back sides is used as the space for placing the car keys. However, the overall structure of this car key case is relatively flat and flexible. Inferior, car keys are often difficult to put in and take out. After long-term use, it is very easy to break the line and crack the skin. It is not practical and affects the appearance of the product. Summary of the invention [0004] In order to solve the problems and deficiencies in the prior art, the present invention provides a three-dimensional stereotyped car key case manufacturing process. ...
