Description

Technical Field

[0001] The utility model relates to a mould, in particular to a stretching and trimming mould for a motor casing, belonging to the technical field of moulds. Background Art

[0002] An electric motor is a device that converts electrical energy into mechanical energy. It uses an energized coil (i.e., stator winding) to generate a rotating magnetic field and acts on a rotor (such as a squirrel-cage closed aluminum frame) to form a magnetic-electrodynamic rotating torque. Electric motors are divided into DC motors and AC motors according to the power supply used. Most of the electric motors in the power system are AC motors, which can be synchronous motors or asynchronous motors (the speed of the motor stator magnetic field and the speed of the rotor rotation do not maintain synchronous speed). The electric motor is mainly composed of a stator and a rotor. The direction of the force on the current-carrying wire in the magnetic field is related to the direction of the current and the direction of the magnetic flux lines (magnetic field direction). The working principle of the electric motor is the effect of the magnetic field on the force on the current, which causes the motor to rotate.

[0003] During the processing of the motor casing, it needs to be trimmed. The existing trimming process is mostly done by directly pulling the casing apart. This method has low processing accuracy and is prone to burrs at the trimming. If rotary cutting is used for processing, the mold structure is complex and the maintenance cost is high.

[0004] In order to solve the above technical problems, a cutting and trimming die for a motor casing is proposed. Utility Model Content

[0024] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0025] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0026] like Figure 1 As shown in FIG. 4 , an embodiment of the utility model provides a pulling and trimming die for a motor housing, which is composed of an upper die 10 and a lower die 20.

[0027] The upper mold 10 includes an upper template 11, a mounting seat 13 and a molding member 12. The mounting seat 13 is fixedly connected to one side of the upper template 11, and the molding member 12 is installed on one side of the mounting seat 13. The molding member 12 can be replaced according to the processing requirements of different casings.

[0028] The lower mold 20 includes a lower template 21, a fixed plate 23 and a cutter 31. A lower mold groove 27 is integrally formed on one side of the lower template 21. The lower mold groove 27 is used to place the casing and cooperate with the molded part 12 to punch the cutting edge of the casing. The cutter 31 is slidably installed on one side of the lower mold groove 27. The fixed plate 23 is arranged at the bottom of the lower template 21. One side of the fixed plate 23 is evenly distributed and fixedly connected with a fixing rod 32. One end of the fixing rod 32 passes through the lower template 21. The fixing rod 32 passes through one side of the lower template 21 and is slidably connected to the lower template 21. One end of the fixing rod 32 passes through the lower template 21 and is fixedly connected to the cutter 31. The fixing plate 23 and the cutter 31 are connected by the fixing rod 32, so that the cutter 31 completes the cutting edge processing of the casing when the lower template 21 moves. In order to facilitate the fixing of the fixing plate 23 alone, one side of the fixing plate 23 is evenly distributed with first fixing holes 25 to prevent the fixing plate 23 from moving with the lower template 21.

[0029] In one embodiment, in order to enhance the stability of the upper template 11 and the lower template 21 and prevent the upper template 11 from being misplaced, one side of the lower template 21 is evenly distributed and fixedly connected with positioning rods 22, one end of the positioning rods 22 passes through the upper template 11, and the positioning rods 22 pass through one side of the upper template 11 and are slidably connected to the upper template 11.

[0030] In one embodiment, in order to facilitate installation and fixation of the upper template 11 and the lower template 21 , second fixing holes 26 are evenly distributed on one side of the upper template 11 and the lower template 21 .

[0031] In one embodiment, in order to prevent the upper template 11 from over-fitting with the lower template 21, a limit member 28 is provided on one side of the lower template 21, and fixing bolts 29 are threadedly connected to one side of the limit member 28 at equal intervals, and one end of the fixing bolt 29 is threadedly connected to the lower template 21. The fixing bolt 29 facilitates the replacement of the limit member 28 and the adjustment of the limit member 28 according to the processing requirements of different casings.

[0032] In one embodiment, in order to facilitate taking out the housing after trimming, an ejection hole 24 is opened on one side of the lower mold plate 21 , and the ejection hole 24 is connected to the lower mold groove 27 .

[0033] When the utility model is working: the casing to be processed is placed in the lower die groove 27, the driving device drives the upper template 11 to move downward, so that the upper template 11 cooperates with the forming member 12 to expand and shape the cutting edge of the casing, so that the cutting edge of the casing is fitted with the lower die groove 27, and after molding, the position fixation of the lower template 21 is released, so that the upper template 11 drives the lower template 21 to move downward together, while the fixed plate 23, the fixed rod 32 and the cutter 31 are kept in place, so that the cutting edge of the casing is in contact with the cutter 31, and the cutter 31 completes the cutting process of the casing. After the cutting process, the upper template 11 is raised, and the casing is ejected through the ejection hole 24 in cooperation with the jacking device.

[0034] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
