Description

Technical Field

[0001] The present invention belongs to the technical field of mold processing, and particularly relates to a forming and processing mold for a motor housing. Background Art

[0002] As an important part of the motor, the motor housing is mainly used to protect the electrical components inside the motor, ensuring the normal operation and safety of the motor. With the continuous development of motor technology, the forming process of the motor housing is also constantly improved and optimized. In modern industry, the manufacturing of motor housings needs to meet multiple requirements such as high strength, good thermal conductivity, and high surface quality. Motor housings are generally made of materials such as aluminum alloy, steel, or cast iron, which have good mechanical properties, corrosion resistance, and relatively light weight. With the expansion of the application fields of motors, the design and manufacturing of motor housings also pay more and more attention to the requirements of lightweight, environmental protection, and intelligence, further promoting the development of advanced manufacturing technologies.

[0003] Motor housings usually have relatively complex geometric shapes and different structures such as protrusions, holes, and grooves. The existing forming and processing molds for motor housings usually adopt a one-time forming method when in use, thus it is difficult to achieve different protrusions and holes, resulting in the need for multiple stampings for the finished motor housing, and thus multiple devices and a large amount of processing time are required. At the same time, the motor housing heats up rapidly during the stamping process, so it contracts when contacting the air after stamping, causing the motor housing to be unable to smoothly separate from the upper and lower molds, affecting the processing efficiency. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the above-mentioned disadvantages of the prior art and provide a forming and processing mold for a motor housing.

[0005] The technical solution adopted to solve the above technical problem is: a forming and processing mold for a motor housing, including a main body, and two shaking mechanisms are installed inside the main body for shaking the motor housing to reduce stress and facilitate demolding. The shaking mechanism includes a track rod. The first straight area and the second straight area for the motor housing to enter and exit the mold are provided inside the track rod. A floating area for vibrating the motor housing is provided between the first straight area and the second straight area. A demolding mechanism is correspondingly installed inside the track rod for driving the motor housing to move along the floating area, thereby assisting in demolding. The demolding mechanism includes two connecting rods, and telescopic inner rods are sleeved inside both connecting rods, and a plurality of support columns that slide along the inside of the track rod are provided inside both inner rods.

[0006] Both sides of the main body are provided with access channels for the entry and exit of the motor housing materials. An operating table is installed inside the main body between the two access channels, and different-shaped bottom mold sets are arranged on the top of the operating table.

[0007] Furthermore, two driving mechanisms for providing rotational power are installed inside the main body. The driving mechanism includes a placement groove opened inside the main body, and a synchronous belt is installed inside the placement groove. Two synchronous wheels are rotated inside the synchronous belt. By rotating one of the synchronous wheels, the other synchronous wheel connected by the synchronous belt is driven to rotate. Two rotating shafts are fixed inside the two synchronous wheels. The other end of one of the rotating shafts is fixedly connected to a first motor, and the synchronous wheel on the outer wall of the rotating shaft is rotated by the first motor to provide power.

[0008] Through the above technical solution, during use, the material is fed in from one of the access channels and then stamped into shape. When the motor housing is gradually formed, the driving mechanisms at the front and rear ends can be used to provide power at this time, which is convenient for the motor housing to be quickly demolded and its position to be replaced. Specifically, the two first motors are started to drive the synchronous wheels on the corresponding rotating shafts to rotate. Under the connection of the corresponding synchronous belts, the rotating shafts on the inner walls of the two synchronous wheels are driven to rotate, thereby providing a rotational power.

[0009] Furthermore, fixed seats are installed at the tops of the two connecting rods and the corresponding built-in rods. A spring is installed between the two fixed seats. Support rods are slidably connected to the outer walls of multiple support columns. The surfaces of the two connecting rods are respectively fixedly connected to the corresponding rotating shafts. Rubber clips of different lengths are installed on the opposite sides of the two support rods. An activity cavity for the rotation of the connecting rods is opened inside the main body. By driving the corresponding connecting rods and built-in rods to rotate through the rotating shafts, multiple support columns slide along the corresponding track rods to vibrate the motor housing.

[0010] Through the above technical solution, when the two driving mechanisms are operating, the demolding mechanism can be used in cooperation at this time, so that the formed motor housing can be demolded along a fixed track and then enter the next mold, enabling the motor housing to be gradually formed. Multi-step stamping can complete the manufacture of complex shapes in a short time, especially suitable for mass production. Specifically, as the two rotating shafts rotate, the two connecting rods and the built-in rods will be driven to rotate, so that multiple support columns will first separate the motor housing from one of the bottom mold sets according to the corresponding track, and then move it to the next bottom mold set, and repeatedly stamp in turn to achieve multi-step forming.

[0011] Furthermore, a chute is provided inside the track rod, and the first straight area, the second straight area, and the floating area are all arranged inside the chute. Multiple support columns pass through the floating areas with corresponding different sizes of arcs, thereby shaking the motor housing during the demolding process.

[0012] Through the above technical solution, with the movement of the driving mechanism and the demolding mechanism, it will drive the shaking mechanism to slightly shake the motor housing during demolding and mold insertion, thereby facilitating the rapid demolding and better entry of the motor housing, and improving the processing efficiency. Specifically, when the built-in rod rotates, it will drive multiple support columns to move along the chute provided inside the track rod. When reaching the pending position of the motor housing, the corresponding motor housing will be clamped at this time. Then, continue to rotate the built-in rod. When the motor housing is initially detached, it will first be stably withdrawn through the second straight area, and then pass through the floating area. Multiple support columns will swing on both sides, thereby driving the motor housing to shake, allowing air to enter the interior and facilitating better detachment. At the same time, a spring installed between the two fixed seats will be pulled, causing the vibration of the support rod due to elastic potential energy, facilitating demolding. Then, continue to pass through the first straight area. Under the rotational force of the built-in rod, it will continue to move upward along the chute. At this time, the resistance and the gravity of the motor housing are not large, and the track sliding can be completely achieved. When encountering a corner, the spring being pulled will contract at this time, enabling the built-in rod to smoothly drive the motor housing to rise and move without crossing the track. It should be noted that the arc of the floating area gradually increases from bottom to top. When inserting the mold, it will quickly align in the center in the first straight area and quickly insert the mold under the shaking of the floating area, thus completing the demolding and mold insertion of the motor housing.

[0013] Further, a clamping mechanism for clamping the motor housing is installed inside the main body. The clamping mechanism includes a diamond plate. Connecting columns are installed on both sides of the diamond plate. The other ends of the two connecting columns are respectively rotatably connected to the corresponding support rods. By rotating the diamond plate, the rubber clips on the support rods at the other ends of the two connecting columns are driven to approach the motor housing. A driving shaft is fixedly connected inside the diamond plate. A second motor fixed inside the main body is installed at the bottom of the driving shaft. The second motor drives the diamond plate at the top of the driving shaft to rotate.

[0014] Through the above technical solution, when the rotating shaft drives the support rods connected to the two connecting rods and the built-in rod to reach the designated position of the motor housing, the clamping mechanism is used to clamp the motor housing at this time. Specifically, start the second motor to drive the diamond plate on the driving shaft to rotate, and then pull the two connecting columns on the diamond plate. Then, the support rod will slide along multiple support columns, so that the multiple rubber clips on the support rod clamp the motor housing with different diameters. It should be noted that the lengths of the multiple rubber clips are different, thus ensuring effective clamping of the motor housing.

[0015] Further, a stamping mechanism formed by stamping is installed inside the main body. The stamping mechanism includes a hydraulic cylinder. A stamping block is installed at the bottom of the hydraulic cylinder. Different top die sets are provided at the bottom of the stamping block. The hydraulic cylinder drives the top die set at the bottom of the stamping block to move downward, and then converges with the bottom die set at the top of the operation table to extrude and form the motor housing.

[0016] Through the above technical solution, when the material for the motor housing enters the main body, the stamping mechanism is started at this time for stamping and forming. Through repeated stamping, it is convenient for the gradual forming of the motor housing, and then the assembly line processing is realized. Specifically, two hydraulic cylinders are started, and their piston rods will drive the top die set at the bottom of the stamping block to move downward, so that the material for the motor housing is extruded and formed between the top die set and the bottom die set. After stamping is completed, it is sent out from another inlet and outlet channel.

[0017] The beneficial effects of the present invention are as follows: (1) By designing the driving mechanism, demoulding mechanism, shaking mechanism and clamping mechanism, when the forming and processing die of the motor housing works, the motor housing can be gradually extruded and formed, reducing the investment in external equipment, and helping the motor housing to be quickly demoulded during the alternation process, improving the processing efficiency; (2) Through the driving mechanism and the demoulding mechanism, when the forming and processing die works, the motor housing is gradually stamped to realize multiple stamping steps. Through step-by-step processing, the stress generated during stamping can be effectively dispersed and controlled, avoiding excessive deformation or cracking of the material, improving the quality and stability of the product. In addition, it can be quickly demoulded, improving the forming speed; (3) By designing the shaking mechanism and the clamping mechanism, during the stamping process, the formed motor housing is shaken to accelerate the contact between the motor housing and the air, reducing the suction force and improving the demoulding speed. At the same time, the high pressure during the stamping process will cause stress to be generated inside the housing, and increasing the shaking releases it, thereby improving the dimensional stability and performance of the housing.

Detailed implementation manners

[0020] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0021] Such as Figures 1 - 10As shown in the figure, a forming and processing die for a motor housing in this embodiment includes a main body 11. Both sides of the main body 11 are provided with access channels 12 for the material of the motor housing to enter and exit. Between the two access channels 12, there is an operating table 13 installed inside the main body 11. On the top of the operating table 13, there is a bottom die set 14 with different shapes. Inside the main body 11, there are two driving mechanisms 2 that provide rotational power. The driving mechanism 2 includes a placement groove 25 opened inside the main body 11, and a synchronous belt 24 is installed inside the placement groove 25. Two synchronous pulleys 23 are rotated inside the synchronous belt 24. By rotating one of the synchronous pulleys 23, the other synchronous pulley 23 connected by the synchronous belt 24 is driven to rotate. Inside the two synchronous pulleys 23, there are rotating shafts 22 fixed. The other end of one of the rotating shafts 22 is fixedly connected to a first motor 21. The first motor 21 drives the synchronous pulley 23 on the outer wall of the rotating shaft 22 to rotate to provide power. When in use, the material is fed in from one of the access channels 12, and then stamping forming is carried out. When the motor housing is gradually formed, at this time, the driving mechanisms 2 at the front and rear ends can be used to provide power, which is convenient for the motor housing to be quickly demolded and the position to be replaced. Specifically, start the two first motors 21 to drive the synchronous pulleys 23 on the corresponding rotating shafts 22 to rotate. Under the connection of the corresponding synchronous belts 24, drive the rotating shafts 22 inside the inner walls of the two synchronous pulleys 23 to rotate, thereby providing a rotational power.

[0022] As Figure 9 shown, the demolding mechanism 3 includes two connecting rods 31, and telescopic inner rods 32 are sleeved inside the two connecting rods 31. Inside the two inner rods 32 and multiple support columns 35 that slide along the inside of the track rod 41. Fixed seats 33 are installed at the tops of the two connecting rods 31 and the corresponding inner rods 32. A spring 34 is installed between the two fixed seats 33. The outer walls of the multiple support columns 35 are all slidably connected to support rods 37. The surfaces of the two connecting rods 31 are respectively fixedly connected to the corresponding rotating shafts 22. Different lengths of rubber clips 36 are installed on the opposite sides of the two support rods 37. An activity cavity 38 for the connecting rods 31 to rotate is opened inside the main body 11. By driving the corresponding connecting rods 31 and inner rods 32 to rotate through the rotating shafts 22, the multiple support columns 35 slide along the corresponding track rods 41 to vibrate the motor housing. When the two driving mechanisms 2 are operating, at this time, the demolding mechanism 3 can be used in cooperation with it, so that the formed motor housing can be demolded along a fixed track and then enter the next die, enabling the motor housing to be gradually formed. Multi-step stamping can complete the manufacturing of complex shapes in a short time, especially suitable for mass production. Specifically, as the two rotating shafts 22 rotate, they will drive the two connecting rods 31 and inner rods 32 to rotate, so that the multiple support columns 35 will first separate the motor housing from one of the bottom die sets 14 according to the corresponding track, and then move to the next bottom die set 14, and repeatedly stamp in turn to achieve multi-step forming.

[0023] As Figure 2 , Figure 6 and Figure 9 shown, two shaking mechanisms 4 are installed inside the main body 11 for shaking the motor housing to reduce stress and facilitate demolding. The shaking mechanism 4 includes a track rod 41. Inside the track rod 41, there are a first straight area 43 and a second straight area 45 for the motor housing to enter and exit the mold. Between the first straight area 43 and the second straight area 45, there is a floating area 44 for vibrating the motor housing. A demolding mechanism 3 is correspondingly installed inside the track rod 41 for driving the motor housing to move along the floating area 44 to assist in demolding. A chute 42 is provided inside the track rod 41. The first straight area 43, the second straight area 45, and the floating area 44 are all arranged inside the chute 42. Multiple support columns 35 float through the floating area 44 with different arc sizes to shake the motor housing during the demolding process. With the movement of the driving mechanism 2 and the demolding mechanism 3, it will drive the shaking mechanism 4 to slightly shake the motor housing during demolding and mold insertion, thereby facilitating the rapid demolding of the motor housing and better entry, improving the processing efficiency. Specifically, when the built-in rod 32 rotates, it will drive multiple support columns 35 to move along the chute 42 provided inside the track rod 41. When reaching the pending position of the motor housing, the corresponding motor housing will be clamped. Then, continue to rotate the built-in rod 32. When the motor housing is initially detached, it will first be stably withdrawn through the second straight area 45, and then pass through the floating area 44. Multiple support columns 35 will swing on both sides to drive the motor housing to shake, allowing air to enter the interior for better detachment. At the same time, a spring 34 installed between two fixed seats 33 will be pulled, causing the support rod 37 to vibrate due to elastic potential energy to facilitate demolding. Then, continue to pass through the first straight area 43. Under the rotational force of the built-in rod 32, it will continue to move upward along the chute 42. At this time, the resistance and the gravity of the motor housing are not large, and the track sliding can be completely achieved. When encountering a corner, the pulled spring 34 will contract at this time, enabling the built-in rod 32 to smoothly drive the motor housing to rise and move without crossing the track. It should be noted that the arc of the floating area 44 gradually increases from bottom to top. When inserting the mold, it will quickly align in the center in the first straight area 43 and quickly insert the mold under the shaking of the floating area 44, thereby completing the demolding and mold insertion of the motor housing.

[0024] As Figure 10As shown in the figure, a clamping mechanism 5 for clamping the motor housing is installed inside the main body 11. The clamping mechanism 5 includes a diamond plate 53. Connecting columns 54 are installed on both sides of the diamond plate 53. The other ends of the two connecting columns 54 are rotatably connected to the corresponding support rods 37. By rotating the diamond plate 53, the support rods 37 on the other ends of the two connecting columns 54 drive the rubber clamps 36 thereon to approach the motor housing. A drive shaft 52 is fixedly connected inside the diamond plate 53. A second motor 51 fixed inside the main body 11 is installed at the bottom of the drive shaft 52. The second motor 51 drives the diamond plate 53 at the top of the drive shaft 52 to rotate. When the rotating shaft 22 drives the two connecting rods 31 and the support rods 37 connected to the built-in rod 32 to reach the designated position of the motor housing, the clamping mechanism 5 is used to clamp the motor housing at this time. Specifically, the second motor 51 is started to drive the diamond plate 53 on the drive shaft 52 to rotate, and then the two connecting columns 54 on the diamond plate 53 are pulled. Subsequently, the support rods 37 will slide along the multiple support columns 35, so that the multiple rubber clamps 36 on the support rods 37 clamp motor housings with different diameters. It should be noted that the lengths of the multiple rubber clamps 36 are different, so as to ensure effective clamping of the motor housing.

[0025] As Figure 8 shown in the figure, a stamping mechanism 6 for stamping is installed inside the main body 11. The stamping mechanism 6 includes a hydraulic cylinder 61. A stamping block 62 is installed at the bottom of the hydraulic cylinder 61. Different top die sets 63 are provided at the bottom of the stamping block 62. The hydraulic cylinder 61 drives the top die set 63 at the bottom of the stamping block 62 to move downward, so as to meet the bottom die set 14 at the top of the operating table 13 and extrude the motor housing into shape. When the material for the motor housing enters the main body 11, the stamping mechanism 6 is started at this time to perform stamping and forming. Through repeated stamping, it is convenient for the gradual forming of the motor housing, and thus the assembly line processing is realized. Specifically, the two hydraulic cylinders 61 are started, and their piston rods will drive the top die set 63 at the bottom of the stamping block 62 to move downward, so that the material for the motor housing is extruded and formed between the top die set 63 and the bottom die set 14. After stamping is completed, it is sent out from another access channel 12.

[0026] The working principle of this embodiment is as follows. When in use, the material is fed from one of the inlet and outlet channels 12, and the stamping mechanism 6 is started to perform stamping and forming. Through repeated stamping, the motor housing is gradually formed, thereby realizing assembly line processing. Specifically, the two hydraulic cylinders 61 are started, and their piston rods will drive the top die set 63 at the bottom of the stamping block 62 to move downward, so that the motor housing material is extruded and formed between the top die set 63 and the bottom die set 14. When the stamping is completed, the two first motors 21 are started to drive the synchronous wheels 23 on the corresponding rotating shafts 22 to rotate, and the corresponding synchronous belts 24 are connected. Next, the rotating shaft 22 on the inner wall of the two synchronous wheels 23 is driven to rotate. As the two rotating shafts 22 rotate, the two connecting rods 31 and the built-in rod 32 are driven to rotate. When the rotating shaft 22 drives the two connecting rods 31 and the support rod 37 connected to the built-in rod 32 to reach the specified position of the motor housing, the second motor 51 is started to drive the diamond plate 53 on the driving shaft 52 to rotate, and then the two connecting columns 54 on the diamond plate 53 are pulled, and then the support rod 37 slides along the multiple support columns 35, so that the multiple rubber clamps 36 on the support rod 37 clamp the motor housings of different diameters. When the built-in rod 32 rotates, it will drive multiple support columns 35 to move along the slide groove 42 set inside the track rod 41. When the motor housing reaches the pending position, the corresponding motor housing is clamped, and then the built-in rod 32 continues to rotate. When the motor housing is initially separated, it will first pass through the second straight area 45 for stable withdrawal, and then pass through the floating area 44. Multiple support columns 35 will swing on both sides. At the same time, the spring 34 installed between the two fixing seats 33 will be pulled, so that the support rod 37 will vibrate due to the elastic potential energy, and then continue to pass through the first straight area 43, under the rotational force of the built-in rod 32, it will continue to move upward along the slide slot 42. When encountering a corner, the pulling spring 34 will shrink, so that the built-in rod 32 can smoothly drive the motor housing to rise and move, and will not cross the track. When entering the mold, it will first be quickly aligned in the center in the first straight line area 43, and then enter the mold. At the same time, start the second motor 51, so that the multiple rubber clips 36 release the corresponding motor housing, and then stamp again, and reciprocate to achieve multi-step stamping in sequence. The formed motor housing is sent out from another inlet and outlet channel 12. At this point, the motor housing forming process is completed.
