Description

Technical Field

[0001] The utility model relates to the technical field of loudspeaker basin frames, in particular to a loudspeaker basin frame punching die. Background Art

[0002] The speaker frame is an important part of the speaker as a support. The speaker frame is usually made through multiple stamping processes. Figure 6 As shown, due to its large size, it is also heavy, and its structure is relatively conventional, resulting in poor aesthetics. To address these issues, multiple sets of decorative holes 903 are designed on the raised platform at the bottom of the existing speaker frame to reduce weight and improve aesthetics. Therefore, a corresponding punching die is urgently needed. Utility Model Content

[0003] The purpose of the utility model is to provide a speaker basin frame punching die, which can punch out flower holes on the basin frame through the cooperation of the punching die, the die hole and the expanded countersunk hole; by providing multiple punching dies, multiple flower holes can be punched out at one time, which can effectively improve the production efficiency of the speaker basin frame.

[0004] The above technical objectives of the present invention are achieved through the following technical solutions:

[0005] A speaker basin frame punching die comprises an upper die and a lower die, wherein the upper die comprises an upper die bottom plate, an upper die positioning plate, and a plurality of evenly distributed punching dies; the plurality of punching dies are arranged with equal spacing around the same center; the upper die positioning plate is fixed to the upper die bottom plate, and the punching dies are fixed to the upper die positioning plate;

[0006] The lower die comprises a lower die bottom plate, a hole die positioning seat and a positioning hole die; the positioning hole die is formed with a plurality of die holes corresponding to the punching die one by one, and an expanded countersunk hole is formed at the upper end of the die hole.

[0007] The upper die base plate is fixed on the punching head of the punching machine, and the lower die base plate is fixed on the bottom platform of the punching machine; the speaker basin frame to be punched is placed on the positioning hole die, and the punching head drives the upper die base plate to move downward, and the upper die base plate drives the die downward through the upper die positioning plate. After the die contacts the basin frame, the corresponding part of the speaker basin frame is first punched into the expanded countersunk hole, and then the die continues to move downward, and the corresponding flower holes are punched out through the cooperation of the die and the die hole. The die is inserted into the die hole, and the cut part is pushed into the die hole and discharged from the bottom.

[0008] The utility model is further configured as follows: the positioning hole die includes an arc boss, and an arc positioning groove is formed on the upper end of the arc boss;

[0009] Positioning protrusions are formed on both ends of the arc boss.

[0010] The inner annular boss of the speaker basin frame is inserted into the arc positioning groove, and the inner wall of the arc-shaped arm of the speaker basin frame is pressed against the positioning boss, thereby positioning the speaker basin frame, so that the position of the hole punched by the die is more prepared.

[0011] The utility model further features a trough formed within the die locating base, communicating with the bottoms of the multiple die holes. The trough's lower surface is higher on the inside and lower on the outside, with its lower end extending to one of the side walls of the die locating base. Waste material from the speaker frame, punched out of the die, enters the trough through the die holes and is discharged from the trough. The trough's bottom is tilted, allowing the waste material to slide down and out automatically.

[0012] The utility model is further configured as follows: the lower ends of the plurality of punching dies are inserted and sleeved on the pre-pressing plate, and the pre-pressing plate is fixed to the upper die positioning plate through a plurality of elastic connecting columns.

[0013] The elastic connecting column is a rubber column.

[0014] The pre-compression plate can pre-compress the speaker basket when the upper die moves downward, making its positioning more accurate. The elastic connecting column can make the pre-compression plate softly compress rather than rigidly compress during the compression process, thereby protecting the speaker basket. At the same time, the pre-compression plate can move relative to the die, and the die shell extends from under the pre-compression plate to perform punching and cutting on the basket.

[0015] The utility model is further configured as follows: a positioning guide sleeve is inserted and fixed on the upper mold bottom plate;

[0016] A positioning guide column aligned with the positioning guide sleeve is fixed to the bottom plate of the lower die, and the positioning guide column and the positioning guide sleeve are arranged with clearance. The cooperation between the positioning guide sleeve and the positioning guide column can make the position of the upper and lower dies more accurate during punching, ensuring smooth punching.

[0017] The outstanding effects of the utility model are:

[0018] Compared with the existing technology, the flower holes can be punched out on the basin frame by cooperating with the punching die, the die hole and the expanded countersunk hole; by providing multiple punching dies, multiple flower holes can be punched out at one time, which can effectively improve the production efficiency of the speaker basin frame;

[0019] The speaker basin frame processed by this mold is lighter and more beautiful, which can increase its market competitiveness. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0034] The following references Figures 1 to 5 The utility model is described as follows:

[0035] A speaker basin frame punching die includes an upper die 1 and a lower die 2. The upper die 1 includes an upper die base plate 10, an upper die positioning plate 11, and a plurality of evenly distributed punching dies 12. The plurality of punching dies are arranged with equal spacing around the same center. The upper die positioning plate is fixed to the upper die base plate, and the punching dies are fixed to the upper die positioning plate.

[0036] The lower die 2 includes a lower die base 20, a hole die positioning seat 21, and a positioning hole die 22. The positioning hole die 22 is formed with multiple die holes 221 corresponding to the punching die 12, and the upper ends of the die holes 221 are formed with flared countersunk holes 222. The positioning hole die 22 includes an arc boss 223, the upper ends of which are formed with an arc positioning groove 224; and the ends of the arc boss 223 are formed with positioning protrusions 225.

[0037] The upper die bottom plate is fixed on the punching head of the punching machine, and the lower die bottom plate is fixed on the bottom platform of the punching machine; the speaker basin frame 9 to be punched is placed on the positioning hole die, and the punching head drives the upper die bottom plate to move downward, and the upper die bottom plate drives the die downward through the upper die positioning plate. After the die contacts the basin frame, the corresponding part of the speaker basin frame is first punched into the expanded countersunk hole, and then the die continues to move downward, and the corresponding flower hole 903 is punched out through the cooperation of the die and the die hole. The die is inserted into the die hole, and the cut part is pushed into the die hole and discharged from the bottom.

[0038] The inner annular boss 901 of the speaker frame 9 is inserted into the arc positioning groove, and the inner wall of the arc-shaped arm 902 of the speaker frame 9 is pressed against the positioning boss, thereby positioning the speaker frame and making the position of the hole punched by the die more prepared.

[0039] Preferably, a chute 211 is formed within the hole die positioning seat 21 and communicates with the bottoms of the plurality of die holes 221. The lower surface of the chute 211 is higher on the inside and lower on the outside, with the lower end of the chute extending to one of the side walls of the hole die positioning seat 21. Waste material from the speaker frame, which is punched out of the die, enters the chute through the die holes and is discharged from the chute.
