Description

Technical Field

[0001] The utility model relates to the technical field of bimetal sheet forming equipment, in particular to a bimetal sheet forming equipment with automatic feeding. Background Art

[0002] Bimetal sheets are usually used in snap-action thermostats as the thermal sensitive elements of the thermostats. In the existing forming process of bimetal sheets, there is a process of stamping and forming metal sheets with different expansion coefficients on both sides of the bimetal sheet to be processed. By stamping and forming the metal sheets on both sides of the bimetal sheet, when the bimetal sheet is heated to a certain temperature, the concave and convex surfaces on both sides will undergo reverse deformation, the original concave surface becomes convex, and the original convex surface becomes concave; when the temperature drops to a certain temperature, the concave and convex surfaces on both sides will reset. By using this characteristic of the bimetal sheet, the connection or disconnection between the two terminals of the thermostat can be realized. When the snap-action thermostat is applied in industries, electrical appliances and other fields, it can play a role in safety protection.

[0003] In the prior art, there is a forming equipment for stamping and forming bimetal sheets. The feeding method for the bimetal sheets is that a whole metal sheet is conveyed to the cutting station of the forming equipment through a feeding belt, the bimetal sheet is cut out on the metal sheet, and then the cut bimetal sheet is conveyed to the forming station.

[0004] In addition, there is also a Chinese invention patent with the publication number of CN104269295B and the patent name of "Bimetal Sheet Automatic Forming Machine", which discloses a forming mechanism for stamping and forming bimetal sheets and also discloses a feeding mechanism; the feeding mechanism includes a material cylinder with the same diameter as the bimetal sheet and a pushing mechanism that can feed the bimetal sheet into the feeding station one by one each time. The material cylinder is arranged vertically. The pushing mechanism includes a bending trolley and a pushing rod below the material cylinder; when the feeding mechanism works, the feeding concave groove of the bending section first remains directly below the material cylinder. Under the action of gravity, one bimetal sheet in the material cylinder will enter the feeding concave groove, and then the bending section is pushed by the trolley cylinder to advance towards the feeding station and make a 90-degree bending movement. When the feeding concave groove aligns with the feeding station, the feeding cylinder then pushes the pushing rod forward to push the bimetal sheet into the feeding station to complete the feeding.

[0005] Although the feeding mechanism of the existing forming equipment can complete the feeding work of the bimetal sheet, there are still the following defects:

[0006] For the existing forming equipment that uses a feeding belt to convey the whole metal sheet to the cutting station for cutting and then conveys it to the forming station for feeding and material input, the remaining parts of the cut metal sheet cannot be utilized, and the material utilization rate is only 60%, resulting in too high cost and too low feeding efficiency;

[0007] In addition, in order to feed the material through the barrel of the feeding mechanism, it is also necessary to set up a bending trolley and a pushing rod of the pushing mechanism to bend the bimetallic strip 90 degrees. On the basis of the feeding mechanism, a pushing mechanism with complicated procedures must also be set up, which undoubtedly increases the tedious work of feeding the bimetallic strip, the feeding efficiency is low, and also increases the manufacturing cost of the molding equipment.

[0057] Next, in combination with the accompanying drawings and specific embodiments, the present invention will be further described. It should be noted that, on the premise of no conflict, the following-described embodiments or technical features can be arbitrarily combined to form new embodiments.

[0058] As Figure 1-8As shown in the figure, an automatic feeding bimetal a forming device is used for stamping and forming the bimetal a of a snap-acting thermostat. The bimetal a automatic forming system includes a control cabinet 91, a workbench 90, a main control module 80, a database 81, a stamping driver 82, a gear disk driver 95, a forming template 93, and a processing station arranged on the forming template 93. Among them, the workbench 90 is arranged on the top of the control cabinet 91. The control cabinet 91 is used to install each control module, system and arrange control circuits. On the workbench 90, a transmission wheel set 83, a cam mechanism 84, a transmission arm 85, the stamping driver 82 and the forming template 93 are installed through a mounting seat 92. A forming gear disk 94 for stamping and forming the bimetal a is arranged between the two forming templates 93.

[0059] The output end of the gear disk driver 95 is connected with a driving gear 96. The driving gear 96 is in transmission engagement with the forming gear disk 94. The gear disk driver 95 is electrically connected to the main control module 80. After obtaining electric energy, the main control module 80 sends an instruction to control the gear disk driver 95 to drive the driving gear 96 and then drive the forming gear disk 94, so that the forming gear disk 94 can rotate between the two forming templates 93.

[0060] The output end of the stamping driver 82 is connected with the transmission wheel set 83. The transmission wheel set 83 is composed of at least two transmission wheels that are mutually driven by a belt. The output end of the transmission wheel set 83 is connected with the cam mechanism 84. One end of the transmission arm 85 is in transmission connection with the cam mechanism 84. The other end of the transmission arm 85 is movably connected with a stamping head 31 through a pulley slider assembly 86. The bimetal a on the forming gear disk 94 is stamped and formed by the stamping head 31, and the two side surfaces of the bimetal a are stamped into concave-convex surfaces with a certain arc height.

[0061] More specifically, the processing station at least includes a loading station 10, a feeding station 20, a forming station 30, an aging station 40, an inspection station 50 and an unloading station 60 which are arranged in sequence according to the processing sequence of the bimetal a. A number of material positioning holes 940 for placing the bimetal a are formed on the forming gear disk 94. The number of material positioning holes 940 is arranged in one-to-one correspondence with the feeding station 20, the forming station 30, the aging station 40, the inspection station 50 and the unloading station 60. That is, when the forming gear disk 94 rotates to a set angle, the bimetal a can be corresponded to the specified station through the material positioning holes 940.

[0062] During the stamping process of the bimetallic sheet a, there are relatively high requirements for the ambient temperature. Controlling the temperature within a certain range can improve the qualified rate of the bimetallic sheet a. Therefore, an oil injection hole is provided on the forming gear disc 94, and the oil injection hole is connected to a temperature control device. The hot oil output by the temperature control device is injected into the interior of the forming gear disc 94 through the oil injection hole to keep the temperature of the forming gear disc 94 constant. For example, when the operating temperature requirement of the bimetallic sheet a is 120 °C and the reset temperature requirement is 100 °C, the constant temperature of the forming gear disc 94 is set to 95 °C, and the concave-convex surface arc height h of the bimetallic sheet a is proportional to the heating temperature value.

[0063] The loading station 10 of the loading station 10 is provided with a loading mechanism 11. The loading mechanism 11 is installed on the workbench 90 through a mounting frame. The loading mechanism 11 has a loading bracket 12, a pushing cylinder 17, a loading chute 13, a storage part 15, a suction nozzle 16 and a loading driver 18. The loading driver 18 includes an X-axis loading cylinder 180 and a Y-axis loading cylinder 181. Both the X-axis loading cylinder 180 and the Y-axis loading cylinder 181 are electrically connected to the main control module 80. An X-axis slide rail 182 and a Y-axis slide rail 183 are provided in the loading direction of the bimetallic sheet a.

[0064] Among them, the loading chute 13 and the pushing cylinder 17 are installed on the workbench 90 through a mounting frame, and the loading chute 13 is inclined on the mounting frame. A blanking port 14 is provided at the lower end of the loading chute 13, and the storage part 15 is arranged on the side lower part of the blanking port 14, so that the bimetallic sheets a fall into the blanking port 14 along the loading chute 13 one by one. The pushing cylinder 17 has a push rod and pushes the bimetallic sheet a falling from the loading chute 13 out of the blanking port 14 to the storage part 15 through the push rod.

[0065] The suction nozzle 16 is arranged on the loading bracket 12. The loading bracket 12 is movably arranged on the Y-axis slide rail 183 through a Y-axis slider. The Y-axis slide rail 183 is a slide rail arranged in the direction of the loading chute 13. The output rod of the Y-axis loading cylinder 181 is connected to the Y-axis slider, so that the Y-axis loading cylinder 181 drives the loading bracket 12 and drives the suction nozzle 16 to slide along the Y-axis slide rail 183 and suck the bimetallic sheet a on the storage part 15.

[0066] In addition, the Y-axis loading cylinder 181 and the Y-axis slide rail 183 are movably arranged on the X-axis slide rail 182 through an X-axis slider. The X-axis slide rail 182 is arranged between the loading chute 13 and the feeding station 20 of the forming template 93. The output rod of the X-axis loading cylinder 180 is connected to the X-axis slider, so that the X-axis loading cylinder 180 drives the loading bracket 12 and drives the suction nozzle 16 to slide along the X-axis slide rail 182 and suck the bimetallic sheet a to the positioning hole 940 of the feeding station 20 to realize automatic feeding operation.

[0067] The forming station 30 is provided with a stamping head 31 and a micrometer regulator 32. The micrometer regulator 32 is installed on the mounting seat 92. The micrometer regulator 32 has a measuring cylinder 320 and a micrometer head 321. The output rod of the measuring cylinder 320 is connected to the micrometer head 321, and the micrometer head 321 is connected to the stamping head 31. When the measuring cylinder 320 receives an instruction from the main control module 80, the measuring cylinder 320 controls the micrometer head 321 to automatically adjust the forming depth of the stamping head 31 on the bimetal sheet a. The adjustment of the forming depth of the stamping head 31 by the micrometer regulator 32 can be adjusted correspondingly according to the heating temperature of the bimetal sheet a. After adjusting the stamping head 31 through the micrometer head 321, the stamping driver 82 drives the stamping head 31 to stamp and form the bimetal sheet a in the positioning hole 940 of the forming gear disk 94 corresponding to the forming station 30.

[0068] The aging station 40 is provided with an aging cylinder 41 and an aging push rod 42. The aging cylinder 41 is installed on the mounting seat 92. The aging cylinder 41 is electrically connected to the main control module 80. When the aging cylinder 41 receives an instruction from the main control module 80, the aging cylinder 41 drives the aging push rod 42 to perform aging treatment on the bimetal sheet a in the positioning hole 940 of the forming gear disk 94 corresponding to the aging station 40. The aging treatment means that the aging push rod 42 performs stamping on the bimetal sheet a again, and the stamping depth of the aging push rod 42 on the bimetal sheet a is shallower than that of the stamping head 31, so as to improve the temperature stability of the bimetal sheet a.

[0069] The detection station 50 is provided with a temperature measurement module 51. The temperature measurement module 51 is used to detect the concave-convex surface arc height h of the bimetal sheet a after stamping and forming and aging treatment, and obtain its temperature value by detecting the arc height of the metal sheets with different expansion coefficients on both sides of the bimetal sheet a.

[0070] The temperature measurement module 51 provided in the embodiment of the present application can adopt a telescopic rod. The end of the telescopic rod is used to touch the concave-convex surface of the bimetal sheet a. A displacement sensor is arranged at the front end of the telescopic rod. The displacement sensor is electrically connected to the main control module 80. The forward / backward displacement of the front end of the telescopic rod is obtained through the displacement sensor, and the forward / backward displacement of the front end of the telescopic rod is equal to the concave-convex surface arc height h of the bimetal sheet a. Thus, the concave-convex surface arc height h of the bimetal sheet a is obtained and the obtained arc height signal is fed back to the main control module 80, and is processed by the main control module 80 and converted into a temperature value.

[0071] In addition, the temperature measurement module 51 can also adopt an infrared ranging sensor. The infrared ranging sensor is electrically connected to the main control module 80. The infrared ranging sensor emits light to the concave-convex surface of the bimetal sheet a, and the concave-convex surface arc height h of the bimetal sheet a is obtained by using the light return time, and the obtained arc height signal is fed back to the main control module 80, and is processed by the main control module 80 and converted into a temperature value.

[0072] The main control module 80 is embedded with a specific programming program, and an algorithm formula capable of converting the arc height signal of the bimetallic strip a into a temperature value has been pre-written in the programming program. The control of the programming program and the algorithm formula will not be elaborated here.

[0073] The database 81 pre-stores a set temperature value. The database 81 is electrically connected to the main control module 80. The main control module 80 converts the arc height signal into corresponding temperature data and compares it with the set temperature value pre-stored in the database 81. If the error value of the comparison result is large, the main control module 80 sends an instruction to control the micrometer regulator 32 to timely adjust the forming depth of the punch 31 on the bimetallic strip a, so as to timely and automatically correct the stamping forming error and improve the processing quality of the bimetallic strip a.

[0074] The discharging station 60 is provided with a discharging air cylinder 61 and a discharging push rod 62. The discharging air cylinder 61 is electrically connected to the main control module 80. When the temperature measuring module 51 detects that the currently processed bimetallic strip a meets the requirements, it feeds back a qualified signal to the main control module 80. The main control module 80 sends an instruction to control the discharging air cylinder 61 to drive the discharging push rod 62 to push out the bimetallic strip a in the positioning hole 940 of the forming gear disk 94 corresponding to the discharging station 60.

[0075] In this way, in the embodiment of the present application, the feeding station 10 is provided with a feeding mechanism 11, which feeds the bimetallic strips a one by one through the feeding groove 13, and the bimetallic strips a fall into the storage part 15 on one side of the lower end of the feeding groove 13; under the control of the main control module 80, the feeding driver 18 of the feeding mechanism 11 drives the suction nozzle 16 to suck the bimetallic strip a on the storage part 15 along the feeding direction, and sucks the bimetallic strip a to the positioning hole 940 of the forming gear disk 94 corresponding to the feeding station 20, and then the punching driver 82 drives the punch 31 to punch and form the bimetallic strip a, so as to complete the automatic feeding and punching and forming of the bimetallic strip a;

[0076] Compared with the previous implementation means of conveying the whole metal strip through the feeding belt and then feeding after cutting, the feeding mechanism 11 of the embodiment of the present application directly feeds the independent bimetallic strips a one by one, and its material utilization rate reaches more than 85%, which is more cost-saving; in addition, compared with the implementation means of using a cartridge for feeding and setting a pushing mechanism to perform a 90-degree bending treatment on the bimetallic strip a, the feeding mechanism 11 of the embodiment of the present application can directly suck the bimetallic strips a one by one to the feeding station 20 without bending the bimetallic strip a, and the structure is simpler, reducing the manufacturing cost of the forming equipment.

[0077] During the processing of the bimetallic strip a above, during the rotation of the forming gear disc 94, it is inevitable that there will be errors between each processing hole and the station positions on the forming template 93. Therefore, a calibration station 70 is provided on the forming template 93, and calibration holes are provided on the forming gear disc 94 and corresponding to the calibration station 70. Of course, corresponding calibration holes are also provided on the calibration station 70 of the forming template 93.

[0078] A calibration cylinder 71 and a calibration push rod 72 are provided at the position of the forming template 93 corresponding to the calibration station 70, and the calibration cylinder 71 is electrically connected to the main control module 80. When the temperature measurement module 51 detects that the arc height h of the concave and convex surfaces of the bimetallic strip a has a large difference from the preset value, the main control module 80 will send an instruction to control the calibration cylinder 71 to drive the calibration push rod 72 to pass through the calibration hole, so that the calibration push rod 72 passes through the calibration holes on the forming template 93 and the forming gear disc 94 in sequence.

[0079] Since each material positioning hole 940 and calibration hole have been pre-opened on the forming gear disc 94, and the hole positions have also been pre-opened on each station of the forming template 93. Under normal circumstances, the hole positions of the forming gear disc 94 can be completely aligned with the hole positions of the forming template 93. Only after the forming gear disc 94 rotates for a long time during operation will there be a problem of misaligned hole positions. Therefore, the one-to-one correspondence between the various type holes on the forming gear disc 94 and the stations and hole positions of the forming template 93 is corrected by the calibration push rod 72, further improving the processing quality of the bimetallic strip a and avoiding the problems of stamping deviation and machine jamming when the bimetallic strip a is stamped and formed.

[0080] In addition to controlling the calibration push rod 72 to correct through the working feedback of the temperature measurement module 51, a specific algorithm can also be written into the programming program of the main control module 80, so that the main control module 80 sends an instruction to control the calibration cylinder 71 to drive the calibration push rod 72 to perform a calibration action every once in a while.

[0081] During the actual processing of the bimetallic strip a, forming stations 30, aging stations 40, and detection stations 50 are provided on the forming templates 93 on both sides of the forming gear disc 94.
