Technical Field
[0001] This utility model relates to the field of automotive parts stamping equipment technology, and in particular to a stamping die for a starter motor housing. Background Technology
[0002] The starter motor, also called a motor, converts the electrical energy of the battery into mechanical energy to drive the engine flywheel to rotate and start the engine. The casing requires the use of stamping dies in the stamping process.
[0003] Existing patent CN219648494U describes a stamping die for a starter motor housing. The process involves inserting the housing into a die cavity, aligning the wire groove on the housing with the positioning plate on a rotary positioner, starting the stamping equipment, and causing the upper die holder to move the punch downwards. Protected by guide sleeves and guide pillars, the upper die holder, upper die fixing plate, and punch descend vertically, ensuring the punch accurately enters the die cavity. Simultaneously, the stamped waste material falls into the discharge hole provided in the die cavity. After the downward movement is complete, the upper die holder moves upwards under the drive of the stamping equipment, causing the punch to disengage from the die cavity, thus completing the stamping process.
[0004] However, in the process of using a stamping die for a starter motor housing according to an existing patent, the device cannot fix housings of different inner diameters because the die used to fix the housing is a fixed structure. As a result, the device cannot stamp housings of different inner diameters. Utility Model Content
[0005] The purpose of this utility model is to provide a stamping die for a starter motor housing, which solves the problem that the aforementioned device cannot stamp housings with different inner diameters because the die used for fixing is a fixed structure.
[0006] To achieve the above objectives, this utility model provides a stamping die for a starter motor housing, including a bottom die base, an upper die base, a punch, and a lifting device. The upper die base is mounted on the bottom die base via the lifting device, and the punch is fixedly mounted on the upper die base. The die also includes a fixing device comprising a fixing plate, a fixing sleeve, a fastening block, a connecting spring, a mounting post, and a pushing assembly. The fixing plate is fixedly mounted on the bottom die base, the fixing sleeve is fixedly mounted on the fixing plate and penetrates the fixing plate, the housing is sleeved on the fixing sleeve, the fastening block is slidably mounted on the fixing sleeve and penetrates the fixing sleeve, the mounting post is fixedly mounted on the fastening block and located inside the fixing sleeve, the connecting spring is sleeved on the fastening block, and both ends of the connecting spring are fixedly connected to the fixing sleeve and the mounting post, respectively. The pushing assembly is mounted on the fixing sleeve.
[0007] The pushing assembly includes a threaded sleeve, a pushing screw, a tapered rod, and a rotating component. The threaded sleeve is fixedly installed inside the fixed sleeve. The pushing screw is threaded through the threaded sleeve. The tapered rod is fixedly installed on the pushing screw and located at one end of the pushing screw near the mounting post. The rotating component is installed on the pushing screw.
[0008] The rotating component includes a rotating column and a rotating rod. The rotating column is fixedly installed on the push screw and located outside the fixed sleeve; the rotating rod is fixedly installed on the rotating column.
[0009] The fixing device further includes a support assembly, which includes a support plate and an electric push rod. The electric push rod is fixedly installed on the bottom mold base, and the support plate is fixedly installed on the output end of the electric push rod.
[0010] The lifting device includes a lifting seat, a guide column, and a cylinder. The guide column is fixedly installed on the bottom mold base; the lifting seat is slidably installed on the guide column; the cylinder is fixedly installed on the bottom mold base, and the lifting seat is fixedly connected to the output end of the cylinder.
[0011] This utility model discloses a stamping die for a starter motor housing. In use, the housing is fitted onto a fixed sleeve. Then, rotating the rotating rod drives the rotating column to rotate. The rotation of the rotating column drives the pushing screw to rotate. The pushing screw, through its threaded engagement with the threaded sleeve, slides along the fixed sleeve towards one side of the mounting column. The pushing screw then drives the tapered rod to move in the same direction. When the two sets of mounting columns contact the conical surface of the tapered rod, the mounting columns, pushed by the tapered rod, drive the upper and lower sets of fastening blocks in the vertical direction. The device moves in the opposite direction and abuts against the inner wall of the housing, thus fixing the housing onto the fixed sleeve. Then, the electric push rod is activated, pushing the support plate upward so that it contacts the outer wall of the housing. Subsequently, driven by the lifting device, the upper die seat drives the punch downward to complete the stamping of the housing. By pushing the two sets of fastening blocks in the vertical direction, the fastening blocks can abut against the inner walls of housings with different inner diameters, thereby completing the fixing and stamping of housings with different inner diameters.

Detailed Implementation
[0017] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.
[0018] The first embodiment of this application is:
[0019] Please see Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the overall structure of a starter motor housing stamping die according to the first embodiment of this utility model. Figure 2 This is a structural schematic diagram of the fixing device according to the first embodiment of this utility model.
[0020] This utility model provides a stamping die for a starter motor housing: it includes a bottom die base 101, an upper die base 102, a punch 103, and a lifting device, and also includes a fixing device. The fixing device includes a fixing plate 104, a fixing sleeve 105, a fastening block 106, a connecting spring 107, a mounting column 108, and a pushing assembly. The pushing assembly includes a threaded sleeve 109, a pushing screw 110, a tapered rod 111, and a rotating component. The rotating component includes a rotating column 112 and a rotating rod 113. The fixing device also includes a support assembly, which includes a support plate 114 and an electric push rod 115. The aforementioned solution solves the problem that the device cannot stamp housings with different inner diameters because the die used for fixing is a fixed structure. The aforementioned solution can be used in the scenario of stamping and fixing starter motor housings, and can also be used to solve the problem of driving the upper die base to lift and lower.
[0021] In this embodiment, by pushing the two sets of fastening blocks 106 in the vertical direction, the fastening blocks 106 can abut against the inner walls of the housings 116 with different inner diameters, thereby completing the fixing of the housings 116 with different inner diameters.
[0022] The fixing plate 104 is fixedly mounted on the bottom mold base 101. The fixing sleeve 105 is fixedly mounted on the fixing plate 104 and passes through the fixing plate 104. The housing 116 is sleeved on the fixing sleeve 105. The fastening block 106 is slidably mounted on the fixing sleeve 105 and passes through the fixing sleeve 105. The mounting post 108 is fixedly mounted on the fastening block 106 and located inside the fixing sleeve 105. The connecting spring 107 is sleeved on the fastening block 106, and its two ends are fixedly connected to the fixing sleeve 105 and the mounting post 108, respectively. The pushing assembly is mounted on the fixing sleeve 105. The fixing plate 104 has a through hole adapted to the fixing sleeve 105. The fastening block... There are two sets of fastening blocks 106, distributed on the upper and lower sides of the fixed sleeve 105. Each fastening block 106 has a square structure. Each set of fastening blocks 106 is connected to a set of connecting springs 107 and a set of mounting posts 108. The mounting posts 108 are welded to the bottom of the fastening block 106. The connecting springs 107 coincide with the center line of the fastening block 106. The pushing component can push the fastening blocks 106 to move. When it is necessary to fix the housing 116, the mounting posts 108 drive the upper and lower sets of fastening blocks 106 to move in opposite directions in the vertical direction through the driving of the pushing component, so that the fastening blocks 106 abut against the inner wall of the housing 116 fitted on the fixed sleeve 105, thereby achieving the fixation of housings 116 with different inner diameters.
[0023] Secondly, the threaded sleeve 109 is fixedly installed inside the fixed sleeve 105; the push screw 110 is threaded through the threaded sleeve 109; the tapered rod 111 is fixedly installed on the push screw 110 and located at the end of the push screw 110 near the mounting post 108; the rotating component is installed on the push screw 110; the threaded sleeve 109 is welded to the inner wall of the fixed sleeve 105, and the inner wall of the threaded sleeve 109 is threaded; the axis of the push screw 110 coincides with that of the threaded sleeve 109; the tapered rod... 111 is welded to the end of the push screw 110. The tapered rod 111 has a tapered structure. The rotating component can drive the push screw 110 to rotate. In use, the rotating component drives the push screw 110 to rotate, so that the push screw 110 pushes the tapered rod 111 to one side of the mounting post 108 through the threaded engagement with the threaded sleeve 109. Under the push of the tapered rod 111, the mounting posts 108 on the upper and lower sides move in opposite directions, thereby achieving the pushing effect on the mounting posts 108.
[0024] Furthermore, the rotating column 112 is fixedly installed on the pushing screw 110 and located outside the fixed sleeve 105; the rotating rod 113 is fixedly installed on the rotating column 112, the axis of the rotating column 112 coincides with that of the pushing screw 110, and there are three sets of rotating rods 113 arranged in a ring on the outer wall of the rotating column 112. The end of the rotating rod 113 is a spherical structure. By rotating the rotating rod 113, the rotating column 112 is driven to rotate, so that the rotating column 112 drives the pushing screw 110 to rotate, thereby achieving the rotation effect of the pushing screw 110.
[0025] Finally, the electric push rod 115 is fixedly installed on the bottom mold base 101; the support plate 114 is fixedly installed on the output end of the electric push rod 115. The electric push rod 115 is fixed on the bottom mold base 101 by screws. The upper end of the support plate 114 has an arc-shaped structure. By electric push, the support plate 114 contacts the housing 116, so that the support plate 114 can support the housing 116, thereby preventing the housing 116 from deforming during the stamping process.
[0026] In this embodiment, during use, the housing 116 is fitted onto the fixed sleeve 105. Then, the rotating rod 113 is rotated, causing the rotating column 112 to rotate. The rotation of the rotating column 112 causes the pushing screw 110 to rotate. The rotation of the pushing screw 110, through its threaded engagement with the threaded sleeve 109, allows it to slide along the fixed sleeve 105 towards one side of the mounting column 108. The pushing screw 110 then drives the tapered rod 111 to move in the same direction. When the two sets of mounting columns 108 contact the conical surface of the tapered rod 111, the mounting columns 108, pushed by the tapered rod 111, cause the upper and lower sets of fastening blocks 106 to move in opposite directions in the vertical direction. The device moves and abuts against the inner wall of the housing 116, fixing the housing 116 onto the fixing sleeve 105. Then, the electric push rod 115 is activated, pushing the support plate 114 upward, so that the support plate 114 contacts the outer wall of the housing 116. Subsequently, driven by the lifting device, the upper die base 102 drives the punch 103 downward, completing the stamping of the housing 116. Thus, by pushing the two sets of fastening blocks 106 in the vertical direction, the fastening blocks 106 can abut against the inner walls of the housing 116 with different inner diameters, thereby completing the fixing and stamping of the housing 116 with different inner diameters.
[0027] The second embodiment of this application is:
[0028] Please see Figure 3 ,in Figure 3 This is a schematic diagram of the overall structure of a starter motor housing stamping die according to the second embodiment of the present invention. Based on the first embodiment, the starter motor housing stamping die of this embodiment further includes a lifting device, which includes a lifting seat 201, a guide column 202 and a cylinder 203.
[0029] In this embodiment, the lifting seat 201 drives the upper mold seat 102 to move synchronously by the cylinder 203, thereby achieving the lifting effect of the upper mold seat 102.
[0030] The guide post 202 is fixedly installed on the bottom mold base 101; the lifting seat 201 is slidably installed on the guide post 202; the cylinder 203 is fixedly installed on the bottom mold base 101, and the lifting seat 201 is fixedly connected to the output end of the cylinder 203. There are two sets of guide posts 202, which are symmetrically distributed on both sides of the bottom mold base 101. The guide post 202 is a cylindrical structure, and a limiting post is provided at the top of the guide post 202. The lifting seat 201 has circular through holes on both sides that match the diameter of the guide post 202. There are also two sets of cylinders 203, which are distributed on both sides of the bottom of the lifting seat 201. In use, the lifting seat 201 moves vertically along the guide post 202 by extending and retracting the output end of the cylinder 203. The movement of the lifting seat 201 drives the upper mold base 102 to move synchronously, thereby achieving the lifting effect of the upper mold base 102.
[0031] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
