[0031] This embodiment provides a microphone hole heat punching mechanism, which can be used to process microphone holes on automobile roof fabrics.
[0032] Please refer to Figure 1-4A microphone hole hot punching mechanism provided in this embodiment includes a stamping drive member 1 and a punch 6. The punch 6 includes a punching member 61 and a mounting member 62. A plurality of punching members 61 are arranged on the mounting member 62. The plurality of punching members 61 correspond one-to-one to the plurality of holes to be processed on the workpiece to be processed. The mounting member 62 is driven to move by the stamping drive member 1, and the mounting member 62 simultaneously drives the plurality of punching members 61 to move synchronously, thereby realizing one-time punching of a plurality of microphone holes. Compared with the punching method in the prior art, the hole opening efficiency is significantly improved.
[0033] Furthermore, if Figure 1 As shown, a residual material collecting sub-cavity 611 is provided inside the punching member 61. The end of the residual material collecting sub-cavity 611 away from the mounting member 62 is opened to form a residual material inlet 6111. During the punching process, the residual material is collected in the residual material collecting sub-cavity 611 through the residual material inlet 6111. A residual material collecting main cavity 621 is provided on the mounting member 62. The residual material collecting main cavity 621 is connected to the other end of the residual material collecting sub-cavity 611, and each residual material collecting sub-cavity 611 is connected to the residual material collecting main cavity 621. During the next punching, the residual material generated by the punching squeezes the residual material in the residual material collecting sub-cavity 611, so that the residual material previously collected in the residual material collecting sub-cavity 611 is squeezed into the residual material collecting main cavity 621, thereby eliminating the residual material cleaning step during the punching process and improving the hole opening efficiency.
[0034] Furthermore, if Figure 1 As shown, the microphone hole hot punching mechanism also includes a heating element 5, which is arranged inside the punch 6 and is used to heat the punching element 61. The high temperature of the punching element 61 is used to remove the burrs on the inner wall of the microphone hole during the punching process, thereby improving the hole opening quality. Specifically, the punch 6 is a heat-conducting structure, and the heating element 5 is arranged inside the mounting element 62. The heat generated by the heating element 5 is transferred to the punching element 61 through the mounting element 62, thereby heating the punching element 61. It should be noted that the heating element 5 can also be arranged inside the punching element 61.
[0035] In addition, the residual material collected in the residual material collection sub-chamber 611 is more easily carbonized by high temperature, and is more likely to agglomerate when squeezed by the residual material generated by the next punching. The carbonized and agglomerated residual material is more likely to fall into the residual material collection main chamber 621, and the residual material that is not completely carbonized continues to be carbonized and agglomerated by high temperature in the residual material collection main chamber 621, making the residual material collection more convenient and preventing the residual material from escaping from the residual material inlet 6111 easily.
[0036] Furthermore, if Figure 1As shown, in order to clean the residual material in the residual material collection cavity 621 in time and improve the hole opening efficiency, the punch 6 is tilted relative to the horizontal plane, and a residual material discharge hole 622 is provided on the side wall of the mounting member 62. The residual material discharge hole 622 is connected to the residual material collection cavity 621, and the residual material discharge hole 622 opens downward, so that the residual material in the residual material collection cavity 621 can be discharged from the residual material discharge hole 622 during the punching process. Among them, the aperture of the residual material discharge hole 622 is larger than the maximum aperture of the residual material inlet 6111, so that the residual material can be smoothly discharged from the residual material discharge hole 622. In addition, the projection of the lower end opening of the residual material discharge hole 622 on the horizontal plane is the first projection, and the first projection and the projection of the workpiece to be processed on the horizontal plane are always arranged at intervals to prevent the residual material from falling on the workpiece to be processed during the discharge process, thereby affecting the hole opening quality. Since the residual materials have been carbonized and agglomerated by high temperature in the residual material collecting sub-cavity 611 and the residual material collecting main cavity 621, it is not easy for the residual materials to fly around when the residual materials are discharged from the residual material discharge hole 622 during the punching process. Figure 1 In this embodiment, the height of the punch 6 gradually decreases along the direction from the mounting member 62 to the punching member 61. In other embodiments, the punch 6 may be tilted in the opposite direction to the workpiece, that is, the height of the punch 6 gradually increases along the direction from the mounting member 62 to the punching member 61. The specific tilting mode of the punch 6 does not affect the discharge of the residual material by the residual material discharge hole 622.
[0037] Furthermore, if Figure 1 As shown, in order to prevent the heating element 5 from blocking the residual material discharge hole 622 during the punching process, so that the residual material cannot be discharged smoothly through the residual material discharge hole 622, in this embodiment, the residual material discharge hole 622 is arranged between the heating element 5 and the punching element 61 along the axial direction of the punch 6. In order to ensure that the residual material can fall from the residual material discharge hole 622 in time, the residual material discharge hole 622 is arranged at one end of the mounting member 62 close to the punching member 61. After the residual material in the residual material collection sub-cavity 611 enters the residual material collection main cavity 621, it is directly discharged from the residual material discharge hole 622 under the action of gravity. In this embodiment, the heating element 5 adopts an electric heating structure, and the heating element 5 can adopt an electric heating structure such as a heating tube, a heating plate, or a heating wire.
[0038] Furthermore, if Figure 1 As shown, in order to observe the discharge of the residual material in the residual material collection cavity 621, a residual material observation hole 623 is provided on the side wall of the mounting member 62, the residual material observation hole 623 is connected with the residual material collection cavity 621, the residual material observation hole 623 opens upward, and the residual material observation hole 623 is arranged between the heating member 5 and the punching member 61 along the axial direction of the punch 6, and is used to observe the discharge of the residual material from the residual material discharge hole 622 through the residual material observation hole 623. If too much residual material is accumulated in the residual material collection cavity 621, the residual material discharge hole 622 can be cleaned in time to remove the residual material accumulated in the residual material discharge hole 622.
[0039] Furthermore, if Figure 2 As shown, the residual material collection sub-chamber 611 includes a residual material guide chamber 6112 coaxially arranged with the residual material inlet 6111, one end of the residual material guide chamber 6112 is connected to the residual material inlet 6111, and the other end is connected to the residual material collection main chamber 621, and the residual material inlet 6111 is a gradually expanding opening. Exemplarily, the residual material inlet 6111 is a conical opening, the residual material guide chamber 6112 is a cylindrical through pipe, and the aperture of the residual material guide chamber 6112 is equal to the minimum aperture of the residual material inlet 6111. It is beneficial for the residual material formed by punching to be collected in the residual material guide chamber 6112 through the residual material inlet 6111. Therefore, after the residual material is squeezed into the residual material guide chamber 6112, it is difficult to fall out from the residual material inlet 6111 again, which effectively prevents the residual material from falling on the workpiece to be processed and affecting the product quality of the microphone hole punching.
[0040] Furthermore, the punching member 61 and the mounting member 62 are an integrally formed structure and can be formed by numerical control machining and electric pulse machining.
[0041] In this embodiment, the heating element 5 is disposed in the residual material collection cavity 621. Specifically, an installation opening is formed at one end of the residual material collection cavity 621 away from the punching element 61, and the heating element 5 can enter the residual material collection cavity 621 from the installation opening. The structure is simple, and the installation and replacement of the heating element 5 are convenient.
[0042] In other embodiments, see Figure 3 A mounting cavity 624 is provided inside the mounting member 62, and the mounting cavity 624 is provided between the total residual material collection cavity 621 and the output end of the stamping drive member 1. The mounting cavity 624 is not connected with the total residual material collection cavity 621, and the heating member 5 is provided in the mounting cavity 624. Since the punch 6 is a heat-conducting structure, the heating member 5 heats the punching member 61 by utilizing the heat transfer of the punch 6 itself when heating in the mounting cavity 624, and the mounting cavity 624 is not connected with the total residual material collection cavity 621, so that the residual material collected in the total residual material collection cavity 621 can be prevented from adhering to the surface of the heating member 5 and affecting the heat transfer.
[0043] For further information, see Figure 4 The microphone hole hot punching mechanism also includes a positioning member 3, which is mounted on the bottom plate 4. The positioning member 3 is located at the end of the punch 6 facing away from the punching drive member 1, and a positioning support profile 31 is provided on the side of the positioning member 3 facing the punch 6. Specifically, the workpiece to be processed is sleeved on the positioning support profile 31 by utilizing the elasticity of the workpiece itself, and the workpiece to be processed is covered and fixed on the positioning support profile 31 by utilizing the elastic deformation of the workpiece to be processed, so as to realize the positioning of the workpiece to be processed. Of course, in other embodiments, due to the different elasticity of the workpiece to be processed, the workpiece to be processed can also be placed on the positioning support profile 31, and then other structures can be used to fix the workpiece to be processed.
[0044] Furthermore, in order to prevent the residual material from being discharged from the residual material discharge hole 622 and falling on the workpiece to be processed during the punching process, thereby affecting the product quality, the first projection and the projection of the workpiece to be processed mounted on the positioning support surface 31 on the horizontal plane are always arranged at an interval, and the residual material discharged through the residual material discharge hole 622 will not fall on the workpiece to be processed.
[0045] Furthermore, if Figure 4 As shown, in order to prevent the punching member 61 from hitting the positioning member 3 during the punching process, an avoidance groove is provided on the positioning support profile 31, and the excess material inlet 6111 of each punching member 61 is arranged directly opposite to the opening of the avoidance groove. In other embodiments, multiple avoidance grooves can also be provided, and the multiple avoidance grooves are arranged one by one with the multiple punching members 61.
[0046] For further information, see Figure 4 The microphone hole hot punching mechanism provided in this embodiment further includes a translation driving member 2, which is mounted on the bottom plate 4. The output end of the translation driving member 2 is connected to a bearing bracket 10, and the bearing bracket 10 and the bottom plate 4 slide in cooperation with each other in the horizontal direction. Specifically, a slide groove is provided on the bearing bracket 10, and a slide rail is provided on the bottom plate 4. The slide groove and the slide rail slide in cooperation with each other to guide the movement of the bearing bracket 10.
[0047] Furthermore, if Figure 4 As shown, a mounting seat 11 is provided on the bearing bracket 10, and the punching drive 1 is fixed on the mounting seat 11. The end of the mounting member 62 away from the punching member 61 is connected to the punch base 8, and the punch base 8 is connected to the output end of the punching drive 1. The punch base 8 and the mounting seat 11 are slidably matched along the axial direction of the punch 6. Specifically, a slide groove is provided on the punch base 8, and a slide rail is provided on the mounting seat 11. The slide groove and the slide rail are slidably matched. The punching drive 1 drives the punch 6 to move axially through the movable connecting member 9 and the punch base 8, and guides the movement of the punch base 8 through the axial sliding match of the punch base 8 and the mounting seat 11 along the punch 6, so as to guide the reciprocating movement of the punch 6.
[0048] The translation drive 2 drives the support bracket 10 to approach the positioning member 3 in the horizontal direction. When the support bracket 10 reaches a suitable distance, it stops. The punch drive 1 drives the punch 6 to punch the workpiece to be processed on the positioning member 3 facing it. Exemplarily, the punch drive 1 and the translation drive 2 are both cylinders. In other embodiments, the punch drive 1 and the translation drive 2 can also use existing linear drive mechanisms such as linear motors or electric push rods, which are not listed here one by one.
[0049] Furthermore, if Figure 4As shown, the output end of the stamping drive 1 is connected to a movable connecting member 9, and the punch base 8 is clamped on the movable connecting member 9, so that the punch base 8 is detachably connected to the output end of the stamping drive 1, so that the punch 6 can be easily replaced according to the operation requirements.
[0050] Furthermore, if Figure 4 As shown, a drag chain 12 is installed on the bottom plate 4 to assist in routing the lines and air pipes of the stamping drive component 1, the translation drive component 2, the heating component 5, etc., to prevent the lines from being damaged during operation.
[0051] Furthermore, if Figure 4 As shown, in order to prevent the heat of the punch 6 from being transferred to the punch driver 1 during the punching process and damaging the punch driver 1, a heat insulating member 7 is provided between the mounting member 62 and the punch base 8, and the mounting member 62 and the heat insulating member 7 are fixed to the punch base 8 by fasteners such as screws. Preferably, the heat insulating member 7 can be an epoxy resin board.
[0052] The specific working process of the microphone hole heat punching mechanism provided in this embodiment is as follows:
[0053] S1. Control the heating element 5 to heat the punching element 61, and fix the workpiece to be processed on the positioning support profile 31 of the positioning element 3. The translation drive element 2 drives the supporting bracket 10 to translate to a preset position, so that the projection of the residual material discharge hole 622 on the horizontal plane and the projection of the workpiece to be processed installed on the positioning support profile 31 on the horizontal plane are always spaced apart.
[0054] S2. The punch 6 is driven by the stamping driving component 1 to move axially so that the punch 6 is close to the workpiece to be processed, and the workpiece is punched to form a microphone hole. When the punching is completed, the punch 6 is driven by the stamping driving component 1 to move in the opposite direction to reset the punch 6. After the workpiece to be processed fixed on the positioning component 3 is replaced, the punch 6 is controlled to perform the next punching.
[0055] In the present embodiment, the workpiece to be processed mainly refers to high-elastic leather. Of course, in other embodiments, the workpiece to be processed can also be various fabrics, such as non-woven fabrics, knitted fabrics, etc. The specific size of the punch 6 can be adjusted according to the punching requirements of different fabrics.
[0056] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The contents of this specification should not be understood as limiting the present invention.
