Description

Technical Field

[0001] The present invention belongs to the technical field of inductance cold pressing, and specifically relates to an integrated inductance cold pressing device and process. Background Technique

[0002] An inductor generally refers to an inductive element that can convert electrical energy into magnetic energy and store it. Its structure is similar to that of a transformer, but it has only one winding. The integrated molding of the inductor is to simplify the production process and reduce production costs. During the molding process, magnetic powder and wire windings need to be combined into an integral structure. Cold pressing can make the magnetic powder tightly wrap the wire winding under pressure at room temperature, without the need for additional processes such as heating and cooling. Just apply pressure at room temperature to complete the molding. The production cycle is short, which can improve production efficiency and simplify the production process. It is generally made by a cold pressing forming machine.

[0003] However, when the machine is in use, the upper and lower molds need to be replaced according to the different shapes of the workpieces produced. However, the existing device cannot disassemble and install the upper and lower molds synchronously, which means that the device cannot replace the upper and lower molds synchronously, resulting in an increase in the downtime of the device and a reduction in the production efficiency of the device. At the same time, there are likely to be errors between the installed upper and lower molds, resulting in inaccurate relative positions between the upper and lower molds. During the cold pressing molding process, problems such as workpiece offset and deformation are likely to occur, affecting the product size and shape accuracy while also reducing the production effect of the device.

[0014] The present invention also provides an integrated inductor cold pressing process, comprising the following steps: S1. When cold pressing inductors of different sizes and shapes for production, the mold is installed and removed by operating the rotational retaining device; S2. Under the action of the input drive synchronization component, the loading and unloading operations of the mold are synchronously controlled; S3. The pneumatic stop control unit is used to control the loading and unloading state of the mold by the device, so that the installed mold can be limited, and the dislocation phenomenon can be avoided after continuous cold pressing operations at the mold by the device.

[0015] Compared with the prior art, the beneficial effects of the present invention are: (1) By rotating the active rotating shaft, the two active pulleys are synchronously driven to rotate, and under the action of the transmission belt, the driven pulleys are driven to rotate, so that the rotating shafts on the two driven pulleys rotate synchronously, and the rotation and displacement fixing device can be synchronously operated for the installation and disassembly operations of the mold. Moreover, the installation and disassembly operations are carried out synchronously, which avoids increasing the downtime of the device when replacing the mold, improves the production efficiency of the device, avoids errors between the two installed molds, makes the relative positions of the two molds accurate during use, and avoids problems such as offset and deformation of the inductor during the cold pressing process, which affect the dimensional and shape accuracy of the product, thus improving the production effect of the device; at the same time, when synchronously loading and unloading the two molds, a common drive source is used, which reduces the cost of the device during use, reduces the limitations of the device during use, and improves the cold pressing effect of the device; (2) After the rotation and displacement fixing device completes the installation operation of the mold, by loosening the pull-out square column, it is reset and moved under the action of the limit spring and the extrusion spring, so that the gas between the positioning air pipe and the rectangular square plate is sent into the U-shaped pipe under the condition that the two rectangular square plates are reset and moved. The gas in the U-shaped pipe moves to its two output ends and acts on the guiding column body, so that the guiding column body moves towards the direction of the rotating gear, which means that the guiding cross plate moves. The guiding cross plate drives the stop tooth block to move and engage with the rotating gear under the action of the guiding sliding column, so that the rotating gear can be limited and cannot rotate, and the fixing square cylinder cannot move continuously after installing the mold, thus avoiding the phenomenon of mold dislocation or shaking due to non-human factors during use, improving the installation effect of the mold, and ensuring the safety of the mold during use; After the retaining square tube has entered the retaining slot to limit the position of the mold, the retaining square plate is already in the retaining slot and in contact with its side wall at this time, indicating that the retaining square plate has moved into place. By continuing to operate and rotating the rotating shaft, the retaining cross plate continues to drive the retaining square tube to move, so that the retaining square tube is limited and moves within the retaining square plate, and the retaining spring is in a buffered state, thereby further strengthening the connection strength and friction between the retaining slot and the retaining square plate, avoiding the instability or shaking of the mold caused by non-human factors during use, and further improving the efficiency and effect of the device during use; at the same time, it avoids the phenomenon of dislocation of the mold caused by the frequent contact of the two molds during the continuous cold pressing process, and improves the loading and unloading effect of the mold; When the mold is disassembled and the guiding cross plate moves away from the rotating gear, the positioning base on the guiding cross plate is limited and slides at the driving base under the action of the positioning square column, and the positioning spring is in a buffered state; when the mold is installed and the guiding cross plate moves back to its original position, the positioning spring moves back to its original position. When the stop tooth block meshes with the rotating gear, the stop tooth block cannot continue to move. Since the strength of the positioning spring is greater than that of the guiding spring, the positioning spring continues to move back to its original position and drives the guiding cross plate to be limited and move on the guiding sliding column, and the guiding spring is in a buffered state, thereby strengthening the connection strength between the stop tooth block and the rotating gear, avoiding the rotation of the rotating gear due to non-human factors, and improving the safety and replacement effect of the mold during use; at the same time, the guiding spring in the buffered state cannot move back to its original position, and the elastic force generated will act on the rotating gear, thereby further strengthening the meshing strength between the rotating gear and the stop tooth block, further avoiding the phenomenon of shaking or dislocation of the mold during use, which affects the production effect and efficiency of the device, and further improving the installation and disassembly effect of the device on the mold; When the upper mold needs to move up and down reciprocally during use, it will cause the positioning air pipe and the air delivery hose to move reciprocally, and at the same time cause the braking cylinder and the braking cylinder to move reciprocally, so that the inclined plane on the braking wedge contacts the inclined plane at the braking chute, resulting in the braking wedge being subjected to extrusion force and the elastic rod being in a buffered state, enabling the device to synchronously load and unload the mold regardless of the position of the upper mold, reducing the limitations of the device during use; and when it is necessary to rotate the braking cylinder and the braking cylinder, they can rotate normally through the contact between the braking wedge and the side wall of the braking chute, avoiding the influence on the synchronous loading and unloading operation of the mold caused by the abnormal rotation between the braking cylinder and the braking cylinder, and improving the use effect of the device; when the braking cylinder continues to move with the upper mold, it will cause another braking chute to move in front of the braking wedge, so that it is no longer subjected to extrusion force and moves back through the elastic rod, so that the braking wedge moves back to the braking chute, so that the position between the braking cylinder and the braking cylinder can be fixed and cannot move when not in use, enabling the braking cylinder and the braking cylinder to expand and contract normally without affecting the synchronous loading and unloading of the mold by the device, reducing the limitations of the device during use, and further improving the cold pressing effect of the device; When it is necessary to replace the mold, the mold needs to be disassembled. Just move the positioning square tube so that it no longer contacts the positioning slot, so that the positioning square plate on the positioning square tube releases the limit on the mold, and the guiding spring in the buffered state is reset, so that the mold can be ejected from the storage box to complete the disassembly operation of the mold; but when it is necessary to install the mold, by moving the adapted mold through the installation slot and continuing to move into the storage box, the mold is limited to move in the storage box and will contact the pressing square plate, so that it is limited to move at the guiding chute and the guiding cylinder, making the guiding spring in a buffered state. Coupled with the buffering force brought by the rubber buffer pad, the impact force encountered by the mold during installation can be reduced, so as to avoid damage to the mold caused by excessive installation force or other non-human factors during the installation process, improving the installation effect and stability of the mold; at the same time, under the action of the rubber buffer pad, the contact friction between the pressing square plate and the mold is increased, avoiding phenomena such as shaking or dislocation of the mold during use, and further improving the safety of the mold during installation; (7) Pull out the draw square column outward, so that the draw cross plate on it is limited to move at the limit cylinder, making the limit spring in a buffered state. At the same time, the gas in the rectangular square tube is pumped into the draw square tube, causing suction in the rectangular square tube and relative movement of the two rectangular square plates inside it, making the compression spring in a buffered state, and making the rectangular square plate move away from the positioning gas transmission pipe, thereby creating suction in the area between the two, so as to suck the gas in the positioning gas transmission pipe into the rectangular square tube. The positioning gas transmission pipe is connected to the gas transmission hose and the U-shaped pipe, causing suction at the two output ends of the U-shaped pipe, so that the guide column can be sucked in. The guide cross plate on it drives the stop tooth block to move away from the rotating gear under the action of the guide sliding column, so that the two are no longer engaged, thus releasing the limit setting of the rotating gear. At this time, the displacement spring in the buffered state is reset because it is no longer limited, thereby driving the retaining square tube to no longer connect to the mold, releasing the limit setting of the mold. And at this time, the mold is no longer limited and without external force, it is ejected from the storage box through the reset of the guiding spring, thus automatically completing the disassembly operation of the mold. The operation is convenient and fast and does not require any tools to complete, improving the disassembly effect of the device on the mold and the efficiency of replacing the mold of the device, and avoiding the reduction of the production efficiency of the device caused by the increase of the downtime of the device. (8) After the mold moves to the maximum position in the storage box, by rotating the rotating shaft, it drives the rotating gear to rotate, making the rotating gear engage the two displacement racks to move relatively. Under the action of the displacement cylinder, they are limited to move on the displacement base, making the displacement spring in a buffered state, so that the limit setting of the mold can be released when it is reset; at the same time, the displacement racks also make the two retaining cross plates move relatively under the action of the bent rod body, making both retaining cross plates move towards the storage box, and then the retaining square tube on the retaining cross plate passes through the storage box and enters the retaining slot, so as to limit the mold in the current position and complete the installation operation of the mold, avoiding phenomena such as dislocation or shaking of the mold during use, and further improving the stability of the mold during installation and use; at the same time, the installation and disassembly of the mold do not require any tools to complete, reducing the limitations of the device during use, enabling the device to perform cold pressing forming operations on inductors of different models and shapes, improving the installation, disassembly effect and efficiency of the mold, and improving the use effect and production efficiency of the device.

A positioning base 42 is also installed on the guiding cross plate 37. A positioning square column 43 is fixedly installed on one side of the positioning base 42 close to the driving base 30. The positioning square column 43 penetrates through the driving base 30 and the two are slidably matched; a positioning spring 44 is sleeved on the positioning square column 43. One end of the positioning spring 44 is fixedly connected to the positioning base 42, and the other end is fixedly connected to the driving base 30; When it is necessary to replace the mold, by pulling out the pull square column 21 outward, the pull horizontal plate 22 thereon is limited to move at the limit cylinder 23, so that the limit spring 24 is in a buffered state. At the same time, the gas in the rectangular square cylinder 3 is pumped into the pull square cylinder 20, causing suction in the rectangular square cylinder 3 and causing the two rectangular square plates 25 inside it to move relative to each other, so that the compression spring 26 is in a buffered state, and the rectangular square plate 25 moves away from the positioning gas transmission pipe 27, thereby creating suction in the area between the two, and being able to suck the gas in the positioning gas transmission pipe 27 into the rectangular square cylinder 3. The positioning gas transmission pipe 27 is connected to the gas transmission hose 28 and the U-shaped pipe 29, causing suction at the two output ends of the U-shaped pipe 29, so that the guiding column 36 can be sucked in, and the guiding horizontal plate 37 thereon drives the stop tooth block 39 to move away from the rotating gear 13 under the action of the guiding sliding column 38, so that the two are no longer meshed and connected, thereby releasing the limit setting of the rotating gear 13. At this time, the displacement spring 18 in the buffered state is reset because it is no longer limited, so as to drive the retaining square cylinder 32 to no longer connect to the mold, releasing the limit setting of the mold. And at this time, the mold is no longer limited and without external force, it is ejected from the storage square box 6 through the reset of the guiding spring 10, thereby automatically completing the disassembly operation of the mold. The operation is convenient and fast and can be completed without any tools, improving the disassembly effect of the device on the mold and the efficiency of replacing the mold of the device, and avoiding the reduction of the production efficiency of the device caused by the increase in the downtime of the device; After the rotation and fixation device completes the installation operation of the mold, by releasing the pull square column 21, it is reset and moved under the action of the limit spring 24 and the compression spring 26, so that the gas between the positioning gas transmission pipe 27 and the rectangular square plate 25 is sent into the U-shaped pipe 29 when the two rectangular square plates 25 are reset and moved. The gas in the U-shaped pipe 29 moves to its two output ends and acts on the guiding column 36, causing the guiding column 36 to move in the direction of the rotating gear 13, indicating the movement of the guiding horizontal plate 37. The guiding horizontal plate 37 drives the stop tooth block 39 to move and mesh with the rotating gear 13 under the action of the guiding sliding column 38, thereby being able to limit the rotation of the rotating gear 13 and making it unable to rotate, so that the retaining square cylinder 32 cannot move further after installing the mold, thereby avoiding phenomena such as dislocation or shaking of the mold due to non-human factors during use, improving the installation effect of the mold, and ensuring the safety of the mold during use; It is worth mentioning that when the mold is disassembled and the guiding cross plate 37 moves away from the rotating gear 13, the positioning base 42 on the guiding cross plate 37 is limited and slides at the driving base 30 under the action of the positioning square column 43, so that the positioning spring 44 is in a buffered state; when the mold is installed and the guiding cross plate 37 moves back to its original position, the positioning spring 44 moves back to its original position. When the stop tooth block 39 meshes with the rotating gear 13, the stop tooth block 39 cannot move further. Since the strength of the positioning spring 44 is greater than that of the guiding spring 40, the positioning spring 44 continues to move back to its original position and drives the guiding cross plate 37 to move in a limited way on the guiding slide column 38, so that the guiding spring 40 is in a buffered state, thereby strengthening the connection strength between the stop tooth block 39 and the rotating gear 13, avoiding the rotation of the rotating gear 13 due to non-human factors, etc., and improving the safety and replacement effect of the mold during use; at the same time, the guiding spring 10 in the buffered state cannot move back to its original position, and the elastic force generated will act on the rotating gear 13, thereby further strengthening the meshing strength between the rotating gear 13 and the stop tooth block 39, further avoiding phenomena such as shaking or dislocation of the mold during use, which affect the production effect and efficiency of the device, and further improving the installation and disassembly effects of the device on the mold.

[0022] The driving and synchronizing components of this embodiment all include a driving rotating shaft 45 installed at the bottom of the auxiliary driving base 5 and the bottom wall of the processing notch. Relative ends of the two driving rotating shafts 45 are both installed with driving pulleys 46. A transmission belt 47 is connected to the driving pulley 46. One end of the transmission belt 47 away from the driving pulley 46 is also connected with a driven pulley 48, and the driven pulley 48 is installed on the rotating shaft 12; the driving pulley 46 and the driven pulley 48 are slidably matched with the transmission belt 47; a braking cylinder 49 and a braking cylinder 50 are respectively installed on opposite surfaces of the two driving pulleys 46. The braking cylinder 50 is located inside the braking cylinder 49 and they are slidably matched; a number of braking inclined slots 51 are provided on the inner side wall of the braking cylinder 49; a braking base 52 is also installed at the end point of the braking cylinder 50 located inside the braking cylinder 49; the braking inclined slot 51 has two symmetrical inclined surfaces, and the two inclined surfaces respectively face the two driving pulleys 46, and the direction of the sharp part of the braking inclined slot 51 is away from the braking base 52; an elastic rod 53 is also installed on one side of the braking base 52 close to the braking inclined slot 51, and a braking inclined block 54 is installed on the elastic rod 53, and one of the braking inclined slots 51 is connected to the braking inclined block 54; When the device is in use, since the two driving rotating shafts 45 are connected through the contact of the two driving pulleys 46, the braking cylinder 49 and the braking cylinder 50, by rotating the driving rotating shaft 45, the two driving pulleys 46 can be synchronously driven to rotate, so that the driven pulley 48 is driven to rotate under the action of the transmission belt 47, so that the rotating shafts 12 on the two driven pulleys 48 rotate synchronously, and the rotating and positioning device can be synchronously operated for the installation and disassembly of the mold. Moreover, the installation and disassembly operations are carried out synchronously, avoiding an increase in the downtime of the device when replacing the mold, improving the production efficiency of the device, avoiding errors between the two installed molds, making the relative positions of the two molds accurate during use, and avoiding problems such as offset and deformation of the inductor during the cold pressing process, which affect the dimensional and shape accuracy of the product, thus improving the production effect of the device; at the same time, when synchronously loading and unloading the two molds, a common drive source is used, which reduces the cost of the device during use, reduces the limitations of the device during use, and improves the cold pressing effect of the device; At the same time, when the upper mold needs to reciprocate up and down during use, it will cause the positioning air delivery pipe 27 and the air delivery hose 28 to reciprocate, and at the same time cause the braking cylinder 49 and the braking cylinder 50 to reciprocate, so that the inclined surface on the braking block 54 contacts the inclined surface at the braking inclined groove 51, resulting in the braking block 54 being subjected to a squeezing force, making the elastic rod 53 in a buffering state, so that the device can synchronously load and unload the mold regardless of the position of the upper mold, reducing the limitations of the device during use; and when the braking cylinder 49 and the braking cylinder 50 need to rotate, they can rotate normally through the contact between the braking block 54 and the side wall of the braking inclined groove 51, avoiding the inability of the braking cylinder 49 and the braking cylinder 50 to rotate normally and affecting the synchronous loading and unloading operation of the mold, improving the use effect of the device; when the braking cylinder 49 continues to move with the upper mold, another braking inclined groove 51 will move in front of the braking block 54, so that it is no longer subjected to a squeezing force and moves back through the elastic rod 53, so that the braking block 54 moves back to the braking inclined groove 51, so that the position between the braking cylinder 49 and the braking cylinder 50 can be fixed and cannot move when not in use, so that the braking cylinder 49 and the braking cylinder 50 can normally expand and contract without affecting the synchronous loading and unloading of the mold by the device, reducing the limitations of the device during use, and further improving the cold pressing effect of the device.
