Description

Technical Field

[0001] The present invention relates to the technical field of intelligent manufacturing, and particularly to a combined stamping die for mobile phone cases used in intelligent manufacturing. Background Technique

[0002] In the intelligent stamping process of metal mobile phone cases, it mainly relies on a manipulator to install the metal mobile phone cases to be processed on the stamping die for stamping processing. After the stamping processing is completed, the processed metal mobile phone cases are transferred by the manipulator, so as to realize the intelligent automatic production of metal mobile phone cases.

[0003] However, in the actual use of the existing intelligent stamping die for metal mobile phone cases, in order to facilitate punching on the side of the metal mobile phone case, the metal mobile phone case needs to be buckled upside down on the stamping die. Since the metal mobile phone case generally adopts an internal buckling structure, when the manipulator disassembles and assembles the metal mobile phone case and the die, the convex edge of the metal mobile phone case and the die are nested, resulting in difficult disassembly and assembly, thus affecting the normal progress of processing. Summary of the Invention

[0004] The purpose of the present invention is to provide a combined stamping die for mobile phone cases used in intelligent manufacturing to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A combined stamping die for mobile phone cases used in intelligent manufacturing, including a bottom plate, columns, a lower fixing plate, and an upper fixing plate. The bottom plate and the lower fixing plate are fixed through columns. An upper fixing plate is arranged above the bottom plate. A side punching mechanism and a front punching mechanism are installed on the lower fixing plate. An activity mechanism is arranged on the lower fixing plate. The activity mechanism is connected to a positioning mechanism. The positioning mechanism includes a front positioning plate and a side positioning plate. The front positioning plate and the side positioning plate are arranged outside the activity mechanism, and the distances between the front positioning plate and the side positioning plate and the inner wall of the lower fixing plate are equal. Guide rods are fixed on both the front positioning plate and the side positioning plate, and the guide rods are slidably connected to a support plate. One end of a connecting rod is rotatably connected to the front positioning plate and the side positioning plate, and the other end of the connecting rod is rotatably connected to a ring. A vertical rod is fixed between the ring and a circular plate. The vertical rod is slidably connected to a movable plate. A fourth spring is fixed between the circular plate and the bottom plate.

[0006] Preferably, guide columns are fixed on the lower end surface of the upper fixing plate, and the guide columns are slidably connected to both the columns and the lower fixing plate. During the assembly of the die, through the sliding guiding action between the guide columns and the columns and the lower fixing plate, the normal assembly of the die can be ensured.

[0007] Preferably, a pressure rod is further fixed to the lower end surface of the upper fixing plate, and the pressure rod is slidably connected to the lower fixing plate. A top plate is fixed to the upper end surface of the upper fixing plate, and a front pressing plate and a side pressing plate are further fixed to the lower end surface of the upper fixing plate. The lower sides of the front pressing plate and the side pressing plate are both inclined surface structures. By moving the upper fixing plate, it can provide a basic guarantee for the functions of the pressure rod, the front pressing plate and the side pressing plate, so as to provide a basic guarantee for the normal operation of the device.

[0008] Preferably, a lower pressing plate is arranged below the upper fixing plate, a round rod is fixed to the lower pressing plate, and the round rod is slidably connected to the upper fixing plate. At the same time, a first spring is fixed between the lower pressing plate and the upper fixing plate. By the action of the lower pressing plate, the mobile phone case can be limited up and down to ensure the normal punching operation.

[0009] Preferably, the side punching mechanism includes a first mounting seat. The first mounting seat is nested with the lower fixing plate. A first punch is slidably connected to the first mounting seat. The first punch is fixed to the first inclined panel through a first sliding rod. The first sliding rod is slidably connected to the first mounting seat. A second spring is further fixed between the first mounting seat and the first inclined panel. The first inclined panel is located below the side pressing plate. Through the above structure, the punching function at the side button position of the mobile phone case can be realized.

[0010] Preferably, the moving mechanism includes a supporting plate. The supporting plate is fixed to the moving plate through a fixing rod. The fixing rod is slidably connected to the circular ring. The distance between the moving plate and the circular plate is equal to the distance between the lower end surface of the supporting plate and the upper end surface of the lower fixing plate. By limiting the distance between the moving plate and the circular plate and the distance between the lower end surface of the supporting plate and the upper end surface of the lower fixing plate, it provides a basic guarantee for the normal operation of the device.

[0011] Preferably, a third spring is fixed between the moving plate and the bottom plate, and the third spring is symmetrically distributed about the center line of the moving plate. By the elastic action of the third spring, it can provide a basic acting force for the automatic reset of the moving plate.

[0012] Preferably, limiting rods are symmetrically fixed to the left and right on the lower end surface of the moving plate, and the distance between the lower end surface of the limiting rod and the bottom plate is equal to the distance between the upper end surface of the supporting plate and the upper end surface of the lower fixing plate. By limiting the distance between the lower end surface of the limiting rod and the bottom plate and the distance between the upper end surface of the supporting plate and the upper end surface of the lower fixing plate, the height positioning of the mobile phone case can be realized to ensure the normal side punching of the mobile phone case.

[0013] Preferably, the movable plate and the movable block are slidably connected, and the movable block has an inclined surface structure. The movable block is also slidably connected to the cross bar fixed on the bottom plate. Meanwhile, the movable block is located below the pressure bar. When the pressure bar moves downward, a force is generated on the movable block, causing the movable block to move, thereby providing a basic force for the movement of the movable plate.

[0014] Preferably, the front punching mechanism includes a second mounting seat. The second mounting seat is nested with the lower fixing plate. A second punch is slidably connected to the second mounting seat. The second punch is fixed to the second inclined panel through a second sliding rod. The second sliding rod is slidably connected to the second mounting seat. A fifth spring is also fixed between the second mounting seat and the second inclined panel. The second inclined panel is located below the front pressing plate. Through the above structure, punching can be achieved at the positions of the charging hole and the speaker hole on the front side of the mobile phone case.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. The combined stamping die for mobile phone cases used in intelligent manufacturing adopts a telescopic support mechanism, which can not only support the side of the metal mobile phone case during side punching processing, but also automatically release the side support of the metal mobile phone case after processing, facilitating the disassembly and assembly of the metal mobile phone case by the manipulator, providing a basic guarantee for the intelligent stamping processing of mobile phone cases;

[0017] 2. The combined stamping die for mobile phone cases used in intelligent manufacturing adopts a stamping automatic positioning mechanism, which can automatically position the metal mobile phone case with respect to the side punching mechanism and the front punching mechanism during punching processing, thus ensuring the normal progress of processing and effectively guaranteeing the processing accuracy. Moreover, both the side punching mechanism and the front punching mechanism adopt nested installation, which is convenient for disassembly, replacement, and improves the convenience of using the device.

One end of a connecting rod 704 is rotatably connected to the front positioning plate 701 and the side positioning plate 702, and the other end of the connecting rod 704 is rotatably connected to a circular ring 705. A vertical rod 706 is fixed between the circular ring 705 and a circular plate 707. The vertical rod 706 is slidably connected to a movable plate 603. A fourth spring 708 is fixed between the circular plate 707 and the bottom plate 1.

[0029] A guide post 401 is fixed to the lower end face of the upper fixing plate 4, and the guide post 401 is slidably connected to both the columns 2 and the lower fixing plate 3; a pressure rod 402 is also fixed to the lower end face of the upper fixing plate 4, and the pressure rod 402 is slidably connected to the lower fixing plate 3. A top plate 403 is fixed to the upper end face of the upper fixing plate 4, and a front pressing plate 404 and a side pressing plate 405 are also fixed to the lower end face of the upper fixing plate 4, and the lower sides of the front pressing plate 404 and the side pressing plate 405 are both inclined plane structures; a lower pressing plate 406 is arranged below the upper fixing plate 4, and a round rod 407 is fixed to the lower pressing plate 406, and the round rod 407 is slidably connected to the upper fixing plate 4. At the same time, a first spring 408 is fixed between the lower pressing plate 406 and the upper fixing plate 4; the activity mechanism 6 includes a support plate 601. The support plate 601 is fixed to a movable plate 603 through a fixing rod 602, and the fixing rod 602 is slidably connected to the circular ring 705. The distance between the movable plate 603 and the circular plate 707 is equal to the distance between the lower end face of the support plate 601 and the upper end face of the lower fixing plate 3; a third spring 604 is fixed between the movable plate 603 and the bottom plate 1, and the third spring 604 is symmetrically distributed about the center line of the movable plate 603; limiting rods 605 are symmetrically fixed to the lower end face of the movable plate 603 in the left and right directions, and the distance between the lower end faces of the limiting rods 605 and the bottom plate 1 is equal to the distance between the upper end face of the support plate 601 and the upper end face of the lower fixing plate 3; the movable plate 603 is slidably connected to a movable block 606, and the movable block 606 is an inclined plane structure, and the movable block 606 is slidably connected to a cross bar 607 fixed to the bottom plate 1. At the same time, the movable block 606 is located below the pressure rod 402;

[0030] When using this combined stamping die for mobile phone cases used in intelligent manufacturing, such asFigures 1-8 As shown, first, the bottom plate 1 and the top plate 403 are installed on the stamping machine. During actual use, the metal mobile phone case to be processed is transferred by a manipulator to contact the upper end faces of the support plate 601, the front positioning plate 701, and the side positioning plate 702, thereby completing the installation of the metal mobile phone case. When punching the metal mobile phone case, the stamping machine drives the top plate 403, the upper fixing plate 4, the guide pillar 401, and the pressing rod 402 to move downward. With the sliding guiding function between the guide pillar 401 and the column 2 and the lower fixing plate 3, the stability of the movement of the top plate 403, the upper fixing plate 4, the guide pillar 401, and the pressing rod 402 can be ensured. When the pressing rod 402 moves downward to contact and slide with the inclined surface of the movable block 606, at this time, the movable block 606 is forced to move. With the sliding guiding function between the movable block 606 and the cross bar 607, the stability of the movement of the movable block 606 can be ensured. When the movable block 606 moves, with the sliding action between the inclined surface of the movable block 606 and the movable plate 603, the movable plate 603 is forced to move downward, thereby driving the fixing rod 602, the support plate 601, the front positioning plate 701, and the side positioning plate 702 to move downward. At this time, the fixing rod 602 is slidably connected to the ring 705, so that the distance between the front positioning plate 701 and the side positioning plate 702 and the ring 705 is reduced. With the transmission function of the connecting rod 704, the front positioning plate 701 and the side positioning plate 702 move outward. With the sliding guiding function between the guide rod 703 and the support plate 601, the stability of the movement of the front positioning plate 701 and the side positioning plate 702 can be ensured. When the movable plate 603 contacts the circular plate 707, at this time, the lower end faces of the support plate 601, the front positioning plate 701, and the side positioning plate 702 are flush with the lower end face of the lower fixing plate 3, and at this time, the front positioning plate 701 and the side positioning plate 702 contact the inner side wall of the metal mobile phone case, thereby realizing the fixing function of the metal mobile phone case. At this time, the pressing rod 402 continues to move downward to make the movable block 606 move, so that the movable plate 603 continues to move downward. At this time, the downward movement of the movable plate 603 synchronously drives the circular plate 707, the vertical rod 706, and the ring 705 to move downward, that is, the support and fixation of the metal mobile phone case are maintained, and the mobile phone case is driven to move downward. When the limit rod 605 contacts the bottom plate 1, at this time, the pressing rod 402 just contacts the flat surface of the movable block 606, thereby realizing the positioning function, and at this time, the upper end face of the support plate 601 is just flush with the upper end face of the lower fixing plate 3, so that the side of the metal mobile phone case is just in position cooperation with the side punching mechanism 5 and the front punching mechanism 8;

[0031] The side punching mechanism 5 includes a first mounting seat 501. The first mounting seat 501 is nested with the lower fixing plate 3. A first punch 502 is slidably connected to the first mounting seat 501. The first punch 502 is fixed to a first inclined panel 504 through a first slide bar 503. At the same time, the first slide bar 503 is slidably connected to the first mounting seat 501. A second spring 505 is also fixed between the first mounting seat 501 and the first inclined panel 504. The first inclined panel 504 is located below the side pressing plate 405. The front punching mechanism 8 includes a second mounting seat 801. The second mounting seat 801 is nested with the lower fixing plate 3. A second punch 802 is slidably connected to the second mounting seat 801. The second punch 802 is fixed to a second inclined panel 804 through a second slide bar 803. At the same time, the second slide bar 803 is slidably connected to the second mounting seat 801. A fifth spring 805 is also fixed between the second mounting seat 801 and the second inclined panel 804. The second inclined panel 804 is located below the front pressing plate 404.

[0032] After the positioning of the metal mobile phone case is completed, as Figures 1-8 shown, at this time, the lower pressing plate 406 does not contact the mobile phone case. The punching machine continues to drive the top plate 403, the upper fixing plate 4, the guide posts 401 and the pressing rods 402 to move downward, so that the lower pressing plate 406, the front pressing plate 404 and the side pressing plate 405 move downward synchronously. When the lower pressing plate 406 contacts the mobile phone, at this time, the front pressing plate 404 just contacts the second inclined panel 804, and the side pressing plate 405 just contacts the first inclined panel 504. When the front pressing plate 404 and the side pressing plate 405 continue to move downward, at this time, with the sliding action between the front pressing plate 404 and the second inclined panel 804 and the sliding action between the side pressing plate 405 and the first inclined panel 504, the second inclined panel 804 and the first inclined panel 504 are forced to move, thereby driving the second slide bar 803, the second punch 802, the first slide bar 503 and the first punch 502. Through the action of the second punch 802 and the first punch 502, the side punching of the metal mobile phone case can be realized. This is the working principle of the mobile phone case combined punching die for intelligent manufacturing.
