Abstract
The utility model discloses a punch die for punching keys comprising a main template and a supporting frame fixed together with the template. A cavum is arranged between the main template and the supporting frame, and the main template is provided with a punching hole, which is characterized in that a guiding plate is arranged between the main template and the supporting frame; the guiding plate is provided with a guiding hole; the shape and distribution of the guiding are the same as those of the punching hole. Because the utility model is provided with a guiding plate, the key can be punched into the key frame in the calculator precisely through the guiding hole in the guiding plate after the key is punched off the main template thanks to the arrangement of the guiding plate, thereby reducing the cases of key jumping and key rotating and enhancing key punching efficiency and product qualification ratio.
Description
Technical field
The utility model relates to the mould that uses in a kind of calculator manufacture craft, particularly a kind of mould of punching out calculator keyboard.
Background technology
Key on the calculator keyboard generally is to be embedded in the calculator upper casing, and these keys are undertaken being fixed in the calculator upper casing key frame towards key by a punch die.That uses in the calculator keyboard manufacturing at present dashes the key punch die structure generally as shown in Figure 1, surrounds a cavity by caster 1 and the bracing frame 3 that is fixed together with it, has punching 11 on the caster 1.During towards the key operation, treat to be fixed in the cavity, place on the bracing frame 3, after key sweeps away the punching 11, fall into the key frame 22 of calculator shell 2 from caster 1 towards the calculator shell 2 of key.The problem that this punch die structure exists is, from caster 1 lower edge to the calculator shell the 2 key frames 22 in this segment distance, key is being done the movement of falling object, key sometimes can occur and can't accurately fall into situation in the key frame 22, some little round keys particularly, the situation of key and rotation is jumped in easier generation, causes the product fraction defective too high, and operating efficiency is low.
The utility model content
The technical problems to be solved in the utility model provides a kind of towards the key punch die, is used for making key accurately to fall into key frame on the calculator shell.
For solving the problems of the technologies described above, the utility model is towards the key punch die, comprise caster and the bracing frame that is fixed together with caster, caster and bracing frame surround a cavity, punching is set on the caster, it is characterized in that, a guide plate is set between caster and bracing frame, pilot hole is set on the guide plate, and the distribution of pilot hole is identical with the distribution and the shape of punching with shape.
The utility model is owing to be provided with guide plate, after key sweeps away from caster, can accurately enter key frame on the calculator shell by the pilot hole on the guide plate, can reduce and jump key and key rotation situation, improves towards key operating efficiency and product percent of pass.
Description of drawings
Fig. 1 is towards key punch die operation schematic diagram in the current techniques;
Fig. 2 is that the utility model is towards key punch die operation schematic diagram.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
The utility model can be with reference to figure 2 towards the structure of key punch die, it comprises caster 1 and the bracing frame 3 that is fixed together with caster 1, caster 1 and bracing frame 3 surround a cavity, punching 11 is set on the caster 1, the distribution of these punchings 11 and shape are corresponding to distribution and the shape for the treatment of the key frame 22 on the calculator shell 2 of key, different with traditional structure shown in Figure 1 is, the utility model is provided with a guide plate 4 between caster 1 and bracing frame 3, pilot hole 44 is set on the guide plate 4, and the distribution of pilot hole 44 is identical with the distribution and the shape of punching 11 with shape.The size of pilot hole 44 is preferably made the size less than correspondent button frame 22 on the calculator shell 2 for the treatment of punching out, size greater than correspondent button, pilot hole 44 is made clear opening, interior smooth, do not have sharp-pointed corner, it is smooth in also accurately being positioned to treat on the calculator shell 2 of punching out from pilot hole 44 to be beneficial to key.Guide plate 4 utilizes principal post and the hot melt post location on the calculator shell 2.
The more excellent size of pilot hole should be than the little 0.25mm of size of correspondent button frame on the calculator shell for the treatment of punching out, and than the big 0.05mm of size of correspondent button, can prevent effectively that like this key is directed to plate when punching out hole from blocking.As, the external diameter of certain key is 4.2mm, then the internal diameter of corresponding pilot hole can be made into 4.25mm.
During operation, after key swept away from caster 1, the pilot hole 44 on the guide plate 4 fell into the key frame 22 on the calculator shell 2, can reduce and jump key and key rotation, improved towards key operating efficiency and qualification rate.
Claims (4)
1, a kind of towards the key punch die, comprise caster and the bracing frame that is fixed together with caster, caster and bracing frame surround a cavity, punching is set on the caster, it is characterized in that, a guide plate is set between caster and bracing frame, pilot hole is set on the guide plate, the distribution of pilot hole is identical with the distribution and the shape of punching with shape.
2, according to claim 1ly it is characterized in that towards the key punch die described pilot hole is the smooth clear opening of internal face.
3, according to claim 1ly it is characterized in that the size of described pilot hole is less than the size of correspondent button frame on the calculator shell for the treatment of punching out towards the key punch die, and greater than the size of correspondent button.
4, according to claim 3ly it is characterized in that towards the key punch die size of described pilot hole is than the little 0.25mm of size of correspondent button frame on the calculator shell for the treatment of punching out, than the big 0.05mm of size of correspondent button.
