Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of mold processing, and particularly relates to a forming and processing mold for a motor shell. BACKGROUND

[0002] As an important component of a motor, a motor shell is mainly used for protecting electrical elements inside the motor to ensure normal operation and safety of the motor. With the continuous development of motor technology, the forming process of the motor shell is also continuously improved and optimized. In modern industry, the manufacturing of the motor shell needs to meet multiple requirements such as high strength, good thermal conductivity, and high surface quality. The motor shell is generally made of aluminum alloy, steel, or cast iron, which has good mechanical properties, corrosion resistance, and light weight. With the expansion of the application field of the motor, the design and manufacturing of the motor shell also pay more and more attention to the requirements of lightweight, environmental protection, and intelligence, further promoting the development of advanced manufacturing technology.

[0003] The motor shell usually has a relatively complex geometric shape and has different protrusions, holes, grooves, and other structures. The existing forming and processing mold for the motor shell usually adopts one-time forming when in use, so it is difficult to realize different protrusions and holes, resulting in the need for multiple stamping of the finished motor shell, and thus multiple equipment and a large amount of processing time are required. In addition, the motor shell is sharply heated during the stamping process, so it shrinks after contacting with air after stamping, causing the motor shell to be unable to smoothly separate from the upper and lower molds, affecting the processing efficiency. SUMMARY

[0004] The technical problem to be solved by the present application is to overcome the shortcomings of the prior art and provide a forming and processing mold for a motor shell.

[0005] The technical solution adopted to solve the above technical problems is: a forming and processing mold for a motor shell, comprising a main body, two shaking mechanisms are installed inside the main body for shaking the motor shell to reduce stress and facilitate demolding.

[0007] The demolding mechanism comprises two connecting rods, and an extendable built-in rod is sleeved inside each of the two connecting rods, and a plurality of support columns are arranged inside the two built-in rods and slide along the track rod.

[0008] The body is provided with an inlet and outlet passage on both sides to provide motor shell material, and an operating table is installed between the two inlet and outlet passages.

[0009] Further, the body is provided with two driving mechanisms inside to provide rotary power, the driving mechanism includes a setting groove opened in the body, and a synchronous belt is installed inside the setting groove, two synchronous wheels are rotated inside the synchronous belt, one of the synchronous wheels drives the other synchronous wheel connected by the synchronous belt to rotate, two synchronous wheels are fixed inside the rotating shaft, one end of the rotating shaft is fixedly connected with a first motor, and the synchronous wheel on the outer wall of the rotating shaft is rotated by the first motor to provide power.

[0010] Through the above technical scheme, when the material is sent from one of the inlet and outlet passages, the material is then punched and formed, and when the motor shell is gradually formed, the driving mechanism at the front and rear ends can provide power, so that the motor shell can be quickly demolded and replaced. Specifically, start two first motors to drive the synchronous wheels on the corresponding rotating shafts to rotate, drive the rotating shafts on the inner walls of the two synchronous wheels to rotate under the corresponding synchronous belt connection, and then provide a rotary power.

An active cavity is provided in the body to provide rotation of the connecting rod, the corresponding connecting rod and the built-in rod are rotated by the rotating shaft, and then the plurality of support columns are slid along the corresponding track rod to realize vibration of the motor shell.

[0012] Through the above technical scheme, when the two driving mechanisms are running, the demolding mechanism can be used to cooperate with it, so that the formed motor shell can be demolded according to the fixed track, and then enter the next mold, so that the motor shell can be gradually formed. Multi-step stamping can complete the manufacturing of complex shape in a short time, especially suitable for mass production. Specifically, the rotation of the two rotating shafts drives the rotation of the two connecting rods and the built-in rods, so that the plurality of support columns can separate the motor shell from one of the bottom die sets according to the corresponding track, and then move to the next bottom die set. In turn, repeated stamping realizes multi-step forming.

[0013] Further, the track rod is provided with a sliding groove, the first straight line area, the second straight line area and the floating area are arranged in the sliding groove, and the plurality of support columns are arranged in the corresponding different size arc floating area, so as to shake the motor shell during demolding.

[0014] Through the above technical scheme, with the movement of the driving mechanism and the demolding mechanism, the shaking mechanism will drive the motor shell to slightly shake when demolding and molding, thereby facilitating the rapid demolding and better entry of the motor shell, improving the processing efficiency.

When encountering a corner, at this time, the spring will be contracted due to the pulling, so that the built-in rod can smoothly drive the motor shell to rise and move, and will not cross the track. It needs to be understood that the floating area gradually increases in curvature from bottom to top. When molding, first, in the first straight line, it will be quickly centered and aligned, under the shaking of the floating area, it will quickly mold, thereby completing the demolding and molding of the motor shell.

Specifically, the second motor is started to drive the rhombic plate on the driving shaft to rotate, then the two connecting columns on the rhombic plate are pulled, then the support rods will slide along the plurality of support columns, so that the plurality of rubber clamps on the support rods clamp the motor shells of different diameters. It needs to be understood that the plurality of rubber clamps have different lengths, thereby ensuring effective clamping of the motor shell.

[0017] Further, the main body is internally provided with a punch forming punch mechanism, the punch mechanism comprises a hydraulic cylinder, the bottom of the hydraulic cylinder is provided with a punch block, the bottom of the punch block is provided with different top die sets, the top die sets at the bottom of the punch block are driven to move downward by the hydraulic cylinder, and then the bottom die sets on the top of the operation table are combined to extrude the motor shell into a shape.

[0018] Through the above technical scheme, when the motor shell material enters the main body, the punch forming punch mechanism is started at this time, and through repeated punching, the motor shell is gradually formed, and then the assembly line processing is realized. Specifically, two hydraulic cylinders are started, the piston rod of the hydraulic cylinder drives the top die set at the bottom of the punch block to move downward, so that the motor shell material is extruded and formed between the top die set and the bottom die set. When the punching is completed, it is sent out from another access channel.
