Description

Technical Field

[0001] The utility model relates to the field of angle line production, in particular to an angle line punching die structure. Background Art

[0002] Corner lines are lines used for decoration and separation of space, and are commonly seen in interior decoration and architecture. Corner lines are usually located at the corners of walls or at the junction of ceilings and walls. Their main function is to beautify the corner area and enhance the interior decoration effect. Corner lines can be made of wood, plaster, metal or other materials. There are multiple through holes on the corner line, which can be used for decoration or to allow plaster to pass through when plaster is applied at the corner of the wall, thereby increasing the stability of the connection between the plaster and the corner line.

[0003] like Figure 1 and Figure 2 The figure shows a conventional corner line punching die structure, which includes an upper template 1' and a lower template 2' that are interlocked, with a corner line receiving groove 3' arranged between the two. The upper template 1' is penetrated with a plurality of punching guide holes 4', which pass through the corner line receiving groove 3' and extend into the lower template 2', and a blanking hole 5' is arranged in the lower template 2'. Among them, at least two punching guide holes 4' correspond to the same blanking hole 5'. Although the structure has a small number of blanking holes 5', due to the large cross-section of the blanking holes 5', in order to ensure the service life of the lower template 2', it is necessary to set the distance D' between the connecting surface of the punching guide hole 4' and the blanking hole 5' and the mold fastening surface 7' to be more than 6 mm, that is, the portion of the punching guide hole 4' located at the lower template 2' is more than 6 mm, but this section of the punching guide hole 4' is relatively long, which will cause a large amount of blanks to accumulate in this section of the punching guide hole 4' when punching the corner line, resulting in a large resistance to the punch 6' during the next punching, shortening the life of the punch 6', and easily bringing up the blanks below when the punch 6' is reset, causing the blanks to re-contact the through-holes on the corner line and making the through-holes on the corner line larger, thereby reducing the dimensional consistency of the finished product. Utility Model Content

[0004] The utility model aims to provide an angle line punching die structure, which has small resistance when the punch head punches holes on the angle line, accurate punching size and can effectively prolong the service life of the template.

[0005] To achieve the above-mentioned purpose, the utility model provides an angle line punching die structure, including a first template and a second template that are interlocked with each other and the contact surface of the two is a locking surface, an angle line accommodating groove is provided between the first template and the second template, and also includes at least two punching guide holes that penetrate the first template, the middle of the punching guide hole passes through the angle line accommodating groove, the end of the punching guide hole extends into the second template and is connected with the blanking hole arranged in the second template; the number of the punching guide holes corresponds to the number of the blanking holes; the distance between the end of the punching guide hole and the locking surface is D, and D is 2-5mm.

[0006] As a further improvement of the utility model, the punching guide hole is perpendicular to the fastening surface.

[0007] As a further improvement of the present invention, the cross-sectional dimension of the blanking hole is larger than the cross-sectional dimension of the punching guide hole.

[0008] As a further improvement of the present invention, the spacing between adjacent punching guide holes is B, and B is not less than 3 mm.

[0009] As a further improvement of the present invention, the spacing between adjacent blanking holes is C, and C is not less than 2 mm.

[0010] As a further improvement of the present invention, the length of the blanking hole is not less than 20 mm.

[0011] As a further improvement of the utility model, a punch adapted to the punching guide hole is also included.

[0012] Beneficial Effects

[0013] Compared with the prior art, the advantages of the corner line die structure of the utility model are:

[0014] 1. Since the distance D between the end of the punching guide hole and the buckling surface is 2-5mm, the amount of blanks that will be temporarily blocked in this part after punching is reduced, and the lower blanks enter the blanking hole faster. The blanks temporarily blocked at the end of the punching guide hole have less resistance to the punch when punching, and it is not easy to lift the newly formed blanks upward when the punch is lifted, avoiding the blanks from contacting the through holes on the corner line, ensuring the high dimensional accuracy of the through holes after the corner line is punched, and ensuring the dimensional consistency of the finished product. The one-to-one correspondence between the number of punching guide holes and blanking holes can increase the number of walls between adjacent blanking holes within a unit projection area, thereby improving the overall rigidity of the second template and extending the service life of the second template.

[0022] Embodiments of the present invention will now be described with reference to the accompanying drawings.

[0023] Example

[0024] The specific implementation of the utility model is as follows Figures 3 to 5 As shown, a corner line punching die structure includes a first template 1 and a second template 2 that are interlocked, and the contact surface between the two is a locking surface 7. An angle line receiving groove 3 is provided between the first template 1 and the second template 2. It also includes at least two punching guide holes 4 that penetrate the first template 1. The middle of the punching guide hole 4 passes through the angle line receiving groove 3. The end of the punching guide hole 4 extends into the second template 2 and is connected to the blanking hole 5 provided in the second template 2. The number of the punching guide holes 4 and the blanking holes 5 corresponds one to one. The distance between the end of the punching guide hole 4 and the locking surface 7 is D, and D is 2-5mm, preferably 3mm.

[0025] In this embodiment, the punching guide hole 4 is perpendicular to the fastening surface 7, and the first template 1 is located directly above the second template 2. The first template 1 is connected to a lifting mechanism (such as a hydraulic cylinder), and the second template 2 is fixed on a base (not shown in the figure). The mutual fastening of the first template 1 and the second template 2 is controlled by operating the lifting mechanism.

[0026] The cross-sectional dimension of the blanking hole 5 is larger than the cross-sectional dimension of the punching guide hole 4. The spacing between adjacent punching guide holes 4 is B, and B is not less than 3 mm. The spacing between adjacent blanking holes 5 is C, and C is not less than 2 mm. The length of the blanking hole 5 is not less than 20 mm. The corner line die structure also includes a punch 6 adapted to the punching guide hole 4. The punch 6 is slidably matched with the punching guide hole 4.

[0027] When in use, place the corner line 8 in the corner line receiving groove 3, and then let the first template 1 and the second template 2 buckle each other. Let the punch 6 enter the punching guide hole 4 of the first template 1 from top to bottom, the punch 6 penetrates the corner line 8 and forms a through hole 81 on the corner line 8, and the blanks of the through hole 81 are pushed down by the punch 6 to the position between the buckling surface 7 and the end of the punching guide hole 4. Open the first template 1 and the second template 2, replace the new corner line 8 and repeat the punching operation. When the blanks between the buckling surface 7 and the end of the punching guide hole 4 reach a certain amount, the blanks of the bottom layer enter the blanking hole 5.

[0028] Since the distance D between the end of the punching guide hole 4 and the buckling surface 7 is 2-5mm, the amount of blanks that will be temporarily blocked in this part after punching is reduced, and the lower layer of blanks enters the blanking hole 5 faster, so the blanks temporarily blocked at the end of the punching guide hole 4 have less resistance to the punch when punching, and it is not easy to lift the newly formed blanks upward when the punch 6 is lifted, avoiding the blanks from contacting the through holes 81 on the corner line 8, ensuring the high dimensional accuracy of the through holes 81 after the corner line 8 is punched, and ensuring the dimensional consistency of the finished product. The number of punching guide holes 4 and blanking holes 5 corresponds one to one, which can increase the number of walls between adjacent blanking holes 5 within a unit projection area, thereby improving the overall rigidity of the second template 2 and extending the service life of the second template 2.

[0029] The present invention is described above in conjunction with the best embodiments, but the present invention is not limited to the embodiments disclosed above, but should cover various modifications and equivalent combinations based on the essence of the present invention.
