Description
Technical Field
The invention relates to the technical field of motor production, in particular to a high-speed stamping progressive die for processing stator and rotor of a multi-type motor.
Background
The stator and the rotor of the motor are formed by stacking a plurality of punching sheets, the punching sheets are formed by punching plates, the punching sheets are required to be cut off by punching the splicing protruding points and the splicing grooves on the plates, punching shaft holes, cutting off gap excess materials and excircle, the manufactured and formed punching sheets are spliced and stacked by the splicing protruding points and the splicing grooves, and the process is completed manually, so that the workload is high, the efficiency is low, and the cost is high. Meanwhile, because of errors, the thickness of the punched sheet is uneven, and fine differences exist.
With rapid development of science and technology and economy, the application of high-speed stamping dies in the field of manufacturing stator and rotor of motor tends to be common. The high-speed stamping die has the advantages of high production efficiency, stable product quality, and compared with manual production, the high-speed stamping die greatly reduces the workload of workers, liberates labor force and reduces the labor cost.
The progressive die is one of stamping dies, and has the following advantages:
(1) A pair of progressive dies can complete multiple working procedures such as blanking, bending, forming, deep drawing and the like. The press can punch one workpiece or process piece per stroke, thus having a higher labor productivity than the compound die.
(2) The continuous die stamping can reduce the equipment, the die number and the workshop area, and the transportation and storage of semi-finished products are omitted.
(3) The continuous die uses coiled materials or belt materials, and the automation of feeding, discharging, lamination and the like is easy to realize. In the stamping process of the automatic continuous die, the human body part does not need to enter a dangerous area, and the operation is safe.
(4) The steps of the progressive die are dispersed at each station, and the problem of 'minimum wall thickness' of the compound die is avoided, so that the die has higher strength and longer service life.
Because of the advantages, progressive dies are currently the first choice for most enterprises to produce stator and rotor laminations.
However, most of the progressive dies used for producing stator and rotor at present are often special dies, namely special dies used for producing stator punching sheets and rotor punching sheets of one type, and cannot be used for producing products of other types. The following two approaches are often required if other models of products are to be produced. A new progressive die is required to be manufactured again, but the cost for manufacturing a new set of dies is very high because the structure of the progressive die is quite complex and the manufacturing precision is much higher than that of a common die; under the condition of not remanufacturing the die, the existing die is required to be disassembled, the positions of a series of elements such as the punching needle and the like in the template are replaced, the technical difficulty and the precision requirement are extremely high, the process is complex, time and labor are wasted, and the manufacturing precision of the die is influenced by repeated disassembly and assembly.
On the other hand, most stator punching sheets produced by the continuous die at present are in the form of scattered sheets, and operators need to stack the stator punching sheets through tools or manually, so that the production period of the stator is prolonged undoubtedly, time and labor are wasted, and the production efficiency is low.
Disclosure of Invention
The invention aims to provide a high-speed stamping continuous die for motor stator and rotor punching sheets, which has the characteristics of high automation degree, high production safety, high production efficiency, long service life and small occupied area, and can produce stator and rotor punching sheets of different types without disassembling the die, so that the problems in the prior art are successfully solved, the high-speed stamping continuous die has higher economy, the manufacturing cost of enterprises is greatly reduced, the utilization rate of belt materials is high, and the number of leftover materials is small; on the other hand, the stator punching sheet produced by the invention is produced in the form of stacked and tidy stator core rough blanks, so that a large amount of time for processing the stator is saved, the production period of the stator is greatly shortened, the production efficiency is improved, and the invention has extremely high practicability and economic benefit.
The technical scheme of the invention is as follows: the high-speed stamping progressive die of the motor stator and rotor punching sheet comprises a machine table, a lower die base provided with a lower die plate and an upper die base provided with an upper die plate, wherein the upper die base is connected with a press on the machine table, and the lower die plate is divided into a section processing area; the first section is sequentially provided with a rotor hysteresis point punching hole and a rotor shaft hole punching hole, a stator cramp groove punching hole is arranged between the rotor hysteresis point punching hole and the rotor shaft hole punching hole, and the rotor shaft hole punching hole is communicated with a wafer outlet on a lower die holder below the rotor shaft hole punching hole; the second section is sequentially provided with an equal-sized A rotor sheet punching hole and a equal-sized B rotor sheet punching hole, a stator buckle slot punching hole is arranged between the equal-sized A rotor sheet punching hole and the equal-sized B rotor sheet punching hole, and a stator buckle point punching hole is arranged at the periphery of the B rotor sheet punching hole; the third section is sequentially provided with a rotor stripping punching hole, an equal-sized A stator punching hole and an equal-sized B stator punching hole, wherein the rotor stripping punching hole is communicated with a rotor sheet outlet on a lower die holder below the rotor stripping punching hole; the fourth section is sequentially provided with a stator stripping hole and a scrap collecting hole, the stator stripping hole is communicated with a stator sheet outlet on a lower die holder of the stator stripping hole, and a movable baffle sheet electrically connected with the pressure sensing device is arranged in a channel communicated with the stator stripping hole and the scrap collecting hole; the outlet of the leftover material collecting hole corresponds to a leftover material collecting basket at the tail end of the machine table; the upper die plate is provided with a punch pin corresponding to a punch hole position on the lower die plate, and the punch pin comprises a fixed punch pin for punching a buckle piece groove and removing materials and a movable punch pin which is adjusted by a screw rod, wherein the movable punch pin is used for punching an inner groove of a stator and rotor punch piece of the motor; and the upper template is also provided with a hysteresis point floating nail for punching the hysteresis points of the stator and the rotor, and the tail end of the hysteresis point floating nail is propped against the hard spring.
Compared with the prior art, the invention has the following beneficial technical effects:
(1) One die can be used for producing two different types of motor stator and rotor: the stamping die can determine the model of the stator and the rotor of the produced motor by adjusting the height of the movable stamping pin through the screw, effectively overcomes the defects of two methods of remanufacturing the die or removing the die in the prior art, has extremely high economic value, greatly reduces the manufacturing cost of enterprises, and simultaneously avoids the influence of removing the die on the die precision;
(2) The utilization rate of the material belt is high: the material belt has extremely high utilization rate, the outer diameter of the rotor sheet corresponds to the inner diameter of the stator sheet, and the workable material sheet area on the material belt is fully utilized; meanwhile, the wafer for punching the rotor shaft hole can produce stator and rotor punching sheets with smaller types;
(3) The stator punching sheet is produced in the form of stacked and tidy stator core rough blanks: through the correction limiting effect of the hysteresis button, the stamped stator punching sheets can be neatly stacked on the movable baffle sheets, the stamping die can repeatedly apply pressure to the stacked stator punching sheets to compress the stator punching sheets, when the stator punching sheets are stacked to a certain amount, the movable baffle sheets are withdrawn, a worker can take out a stator core blank, a large amount of time for processing the stator is saved, the production period of the stator is shortened greatly, and the production efficiency is improved.
As optimization, the lower die plate is provided with two groups of stamping hole sites of the same type. The structure effectively improves the total yield and the production benefit of the invention. The specific number of a group of punching hole sites is calculated by combining the width of the material belt and the size of the stator and rotor punching sheets, and the utilization rate of the material belt is improved on the premise of ensuring the manufacturing precision.
As optimization, two groups of stamping hole sites of the same type on the lower die plate are distributed in a dislocation manner. Because the supporting equipment of the continuous die is often special, such as the width of the material belt, the distribution mode can produce two stator and rotor punching sheets with larger diameters under the condition that the width of the material belt is not required to be increased.
As optimization, a second group of rotor hysteresis point punching holes are arranged between the B rotor sheet punching holes and the rotor blanking punching holes; and a second group of stator hysteresis point punching holes are arranged between the B stator punching holes and the stator stripping holes. Because the hysteresis points are formed by punching the hysteresis point floating nails which are propped against the hard springs, the action of the hysteresis points is very critical, and the stator and the rotor can be produced in a tidy stacked mode through the positioning action of the hysteresis points; two groups of hole sites for punching the hysteresis points are arranged, so that each hysteresis point can be punched twice, and the hysteresis point grooves with enough depth are punched on the surface of the punching sheet. In most cases, rotor laminations are often produced in the form of loose pieces.
As optimization, the lower template is provided with a guide block, and the section shape of the guide block is inverted L-shaped; the guide blocks comprise a pair of long guide blocks and a plurality of small guide blocks, and the long guide blocks are arranged at the feeding end of the lower die plate and extend out of the lower die plate. The inverted L-shaped shape enables a material belt channel to be formed between the material guiding block and the surface of the lower template, the material guiding block is improved to form a limit function on the material belt, the material belt is prevented from being skewed or horizontally displaced, and the manufacturing precision is ensured; the structure of the long guide block carries out limit correction on the material belt in advance before the material belt enters the lower die plate processing area.
As optimization, two rows of guide wheels with a plurality of numbers are arranged on the lower template, and the two rows of guide wheels are distributed in a staggered manner. The guide wheel has a limiting function, and meanwhile, the smoothness of feeding of the material belt can be increased, the influence of friction force on the feeding speed is reduced, and the material belt is ensured to advance at a constant speed; the dislocation distribution mode enables dislocation distribution of corresponding stamping hole sites on one hand, and the dislocation distributed guide wheels on the other hand have a better limiting effect.
As optimization, guide holes are arranged beside each guide wheel, and two rows of guide holes are distributed in a staggered manner. The distribution mode of the guide holes corresponds to the distribution mode of the guide wheels. Further preferably, the first pilot hole of each row corresponds to the pilot punch pin arranged on the upper template, and the rest pilot holes correspond to the pilot pins arranged on the upper template. Two positioning holes are punched on the material belt through the guide punching needle, and along with feeding, the guide punching needle can be inserted into the positioning holes when being pressed down each time, so that the guide belt is accurately positioned, the material belt is effectively prevented from being displaced by force during punching, and the relative position precision of the holes on the parts and the appearance is ensured.
As optimization, a plurality of rectangular guide floating nails are arranged between two rows of guide wheels on the lower die plate, and the tail ends of the guide floating nails are propped against the soft springs. When the feeding can be effectively reduced through the guide floating nails, the contact area between the material belt and the die is reduced, the friction force is reduced, the feeding is smoother, and the accurate feeding speed is ensured.

Description of the embodiments
The invention is further illustrated by the following figures and examples, which are not intended to be limiting.
As shown in fig. 1 to 6, a high-speed stamping progressive die of motor stator and rotor punching sheets comprises a machine table 1, a lower die holder 2 provided with a lower die plate 4 and an upper die holder 3 provided with an upper die plate 5, wherein the upper die holder 3 is connected with a press (punching machine) on the machine table 1; the lower die plate 4 is divided into 4 sections of processing areas; a rotor hysteresis point punching hole 401 and a rotor shaft hole punching hole 402 are sequentially formed in the first section, a stator cramp groove punching hole 403 is formed between the rotor hysteresis point punching hole 401 and the rotor shaft hole punching hole, and the rotor shaft hole punching hole 402 is communicated with a wafer outlet 201 on a lower die holder 2 below the rotor shaft hole punching hole; the second section is sequentially provided with an equal-sized A rotor sheet punching hole 404 and a B rotor sheet punching hole 405, a stator buckle sheet groove punching hole 403 is arranged between the two, and a stator buckle stagnation point punching hole 406 is arranged at the periphery of the B rotor sheet punching hole 405; the third section is sequentially provided with a rotor stripping punching hole 407, an equal-sized A stator punching hole 408 and an equal-sized B stator punching hole 409, wherein the rotor stripping punching hole 407 is communicated with a rotor sheet outlet 202 on a lower die holder 2 below the rotor stripping punching hole; the fourth section is provided with a stator stripping hole 410 and a leftover material collecting hole 411 in sequence, the stator stripping hole 410 is communicated with a stator sheet outlet 203 on the lower die holder 2, and a movable baffle 204 electrically connected with the pressure sensing device is arranged in a channel of the stator sheet outlet 203; the outlet of the leftover material collecting hole 411 corresponds to a leftover material collecting basket 6 at the tail end of the machine 1; the upper die plate 5 is provided with a punch pin corresponding to the punch hole position on the lower die plate 4, the punch pin comprises a fixed punch pin 501 for punching a buckle piece groove and stripping and a movable punch pin 502 regulated by a screw 503, and the movable punch pin 502 is used for punching an inner groove of a stator and rotor punching sheet of a motor (namely a rotor groove of the rotor punching sheet and a stator groove of the stator punching sheet); the upper template 5 is also provided with a hysteresis point floating nail 504 corresponding to the rotor hysteresis point punching hole 401 and the stator hysteresis point punching hole 406, and the tail end of the hysteresis point floating nail 504 is propped against the hard spring.
One side of the machine table 1 is provided with a feeding device 7, the feeding device 7 is provided with a material belt 9 paved on the upper surface of the lower template 4, one side of the machine table 1 is also provided with a control table 8, and the control table 8 is electrically connected with the feeding device 7 and a press (punching machine).
As a specific example: the lower die plate 4 is provided with two groups of punching hole sites of the same type. Namely, the stamping die can simultaneously produce two rotor stamping sheets of the same type and two stator stamping sheets of the same type. The structure effectively improves the total yield and the production benefit of the invention. The specific number of a group of punching hole sites is calculated by combining the width of the material belt 9 and the size of the stator and rotor punching sheets, and the utilization rate of the material belt 9 is improved on the premise of ensuring the manufacturing precision. In the case of large stator and rotor punched sheets, the number of punched hole sites is generally one, and the manufacturing accuracy is lower as the number of punched hole sites is larger.
Two groups of stamping hole sites of the same type on the lower template 4 are distributed in a staggered manner. Because the matching equipment of the progressive die is often special, such as the width of the material belt 9, the distribution mode can produce two stator and rotor punching sheets with larger diameters under the condition that the width of the material belt 9 is not required to be increased.
As a specific example: a second group of rotor hysteresis point punching holes 401 are arranged between the rotor sheet punching holes 405 and the rotor blanking punching holes 407; a second group of stator hysteresis point punching holes 406 are arranged between the B stator punching holes 409 and the stator blanking holes 410. Because the hysteresis points are formed by stamping the hysteresis point floating nails 504 which are propped against the hard springs, the action of the hysteresis points is very critical, and the stator and the rotor can be produced in a tidy stacked mode by the positioning action of the hysteresis points; two groups of hole sites for punching the hysteresis points are arranged, so that each hysteresis point can be punched twice, and the hysteresis point grooves with enough depth are punched on the surface of the punching sheet. In most cases, rotor laminations are often produced in the form of loose pieces.
As a specific example: the lower template is provided with a guide block 412, and the section shape of the guide block 412 is inverted L; the guide block 412 includes a pair of long guide blocks 4121 and a plurality of small guide blocks 4122, the long guide blocks 4121 being provided at the feed end of the lower die plate 4 and protruding from the lower die plate 4. The inverted L shape enables a channel of the material belt 9 to be formed between the guide block 412 and the surface of the lower template 4, so that the limit effect of the guide block 412 on the material belt 9 is improved, the material belt 9 is prevented from being skewed or horizontally displaced, and the manufacturing precision is ensured; the structure of the long guide block 4121 performs a limit correction on the material strip 9 in advance before the material strip 9 enters the processing area of the lower die plate 4.
Two rows of guide wheels 413 with a plurality of numbers are arranged on the lower template 4, and the two rows of guide wheels 413 are distributed in a staggered manner. The guide wheel 413 has a limiting function, and can also increase the feeding smoothness of the material belt 9, reduce the influence of friction force on the feeding speed and ensure that the material belt 9 advances at a uniform speed; the dislocation distribution mode enables dislocation distribution of corresponding stamping hole sites on one hand, and the dislocation distributed guide wheel 413 has a better limiting effect on the other hand.
Guide holes 414 are arranged beside each guide wheel 413, and the two rows of guide holes 414 are also distributed in a staggered manner. The distribution mode of the guide holes 414 corresponds to the distribution mode of the guide wheels 413. The first pilot hole 414 of each row corresponds to a pilot punch pin 505 arranged on the upper template 5, and the rest pilot holes 414 correspond to pilot pins 506 arranged on the upper template 5. Two positioning holes are punched on the material belt 9 through the guide punching needle 505, along with feeding, the guide punching needle 506 is inserted into the positioning holes when being pressed down each time, the material belt 9 is accurately positioned, the material belt 9 is effectively prevented from being displaced by force during punching, and the relative position precision of the holes on the parts and the appearance is ensured.
A plurality of rectangular guide floating nails 415 are arranged between two rows of guide wheels 413 on the lower template 4, and the tail ends of the guide floating nails 415 are propped against the soft springs. The contact area between the material belt 9 and the die during feeding can be effectively reduced through the guide floating nails 415, friction force is reduced, feeding is smoother, and accurate feeding speed is ensured.
A plurality of circular auxiliary floating nails 416 are arranged between two rows of guide wheels 413 on the lower template 4, and the tail ends of the auxiliary floating nails 416 are propped against the soft springs. During punching, the auxiliary floating nails 416 form supporting effect on the surface of the material belt 9, so that punching precision is improved.
Before production, the type of stator and rotor punching sheet to be produced, namely the stator and rotor of the motor A or the stator and rotor of the motor B, is determined. The method specifically comprises the following steps: the heights of the stator and rotor punching needles are adjusted through the screw 503, if the stator and rotor of the motor A are to be produced, the rotor punching needle A and the stator punching needle A are exposed, and the rotor punching needle B and the stator punching needle B are hidden; correspondingly, if the stator and the rotor of the motor B are to be produced, the stator punching needle and the rotor punching needle of the motor B are exposed, and the stator punching needle and the rotor punching needle of the motor A are hidden. For convenience of explanation, we refer to the former as a mode and the latter as B mode. (in terms of the working principle of the die, the invention can simultaneously produce the A rotor punching sheet and the B stator punching sheet or the B rotor punching sheet and the A stator punching sheet, but the stator and the rotor of different motors can not be matched for use in combination with actual production conditions, so that the conditions often do not occur
