Description

Technical Field

[0001] The invention relates to the technical field of gasket production, and in particular to a gasket stamping process for an electric vehicle gearbox. Background Art

[0002] Electric vehicle transmission gasket refers to a key component used for sealing and protection in the electric vehicle transmission system. It is located between the transmission oil pan and the transmission body, and its main function is to prevent transmission oil leakage and ensure the normal operation of the transmission. Electric vehicle transmission gaskets are usually made of advanced synthetic materials such as silicon carbide fiber, inorganic fiber and rubber. These materials have high temperature tolerance, chemical corrosion resistance and pressure resistance, which can ensure that the gasket can still maintain good sealing performance under high temperature and harsh environment.

[0003] Chinese patent CN202310705478.3 discloses a gasket stamping equipment, including a stamping machine body, a storage structure, a pushing structure, a positioning structure, a driving structure and a unloading structure. The storage structure is convenient for storing the workpiece to be stamped, so that the pushing structure can push the workpiece out for stamping processing. The setting of the pushing structure can automatically push the workpiece in the storage structure to the bottom of the stamping head, so that the positioning structure can position it and then perform stamping processing, thereby improving the product processing speed and safety. When the pushing structure pushes the material, the driving structure drives the positioning structure to position and fix the workpiece, thereby avoiding displacement of the workpiece during processing, thereby improving the stamping quality of the product. At the same time, the setting of the positioning structure also avoids the stamped workpiece from being sleeved on the stamping head. The setting of the unloading structure facilitates automatic unloading of the stamped workpiece, thereby improving flexibility.

[0004] However, this technical solution still requires manual loading by workers, which cannot achieve continuous and efficient production, and manual operation has certain risks. Therefore, we proposed a gasket stamping process for electric vehicle gearboxes. Summary of the invention

[0016] A gasket stamping process for an electric vehicle gearbox, the process comprising the following steps:

[0017] Step 1: Loading process, put multiple groups of stamping plates of a certain size into the storage frame for storage. When loading, energize the electric telescopic rod from bottom to top, and the electric telescopic rod pushes the telescopic baffle to move along the telescopic slide rail and enter the storage frame, so as to support the plate loaded from above. During processing, the telescopic baffle is partially retracted to make the stamping plate contact with the main loading roller, and the main loading motor and the auxiliary loading motor are started at the same time. The two sets of motors drive the loading hoop to move, and move the bottom plate to the conveyor belt through the friction between the plate and the plate;

[0018] Step 2: During the transportation process, the transportation motor is powered on. The transportation motor drives the driving shaft to rotate through the driving wheel and the driving belt. The driving shaft drives the conveyor belt to move to transport the sheet. The motor speed in the loading and transportation process is set so that the conveyor belt feed sheet is moved to the stamping platform with the head and tail in contact for subsequent continuous stamping.

[0019] Step 3: Triggering process, when the material plate is transmitted to the loading seat at one end of the lower gasket mold through the conveyor belt, the material plate will contact the traction wheel, and the friction between the material plate and the plate body will drive the traction shaft to rotate. The traction shaft drives the trigger cam at the other end of the trigger shaft to rotate through the coupling. The trigger cam rotates and drives the trigger piston to reciprocate and slide in the piston sleeve through the cam traction rod. Through the control of the speed of the reducer and the transport motor, when the traction wheel travels through the stamping range of a group of material plates, the trigger cam can be set to rotate just one circle, thereby completing a lifting movement of the trigger piston. When the trigger piston moves to the highest point, it contacts the inching switch, and the switch starts the stamping mechanism to complete a stamping operation to achieve continuous operation;

[0020] Step 4: During the stamping process, when the switch is triggered, the hydraulic equipment starts to push the upper gasket die downward through the output rod to contact the lower gasket die, and the material sheet is stamped once through the concave engagement of the die. During stamping, the formed gasket will fall from the holes on the lower gasket die and the bottom die seat, and then be guided to the collection unit through the material seat. The remaining space of the material sheet will be cut off when it passes through the cut-off die during the continuous pushing process, and will be guided into the collection box through the material guide seat for collection. When the stamping is completed, the control unit controls the mold to reset, and triggers the stamping process accurately and continuously through the stroke mode;

[0021] Step 5: Alarm process, when the material plate is normally loaded and stamped, the metal fixing ring will rotate with the trigger shaft. During the rotation, the three sets of conductive telescopic sets consisting of the conductive sleeve, the conductive telescopic rod, the conductive spring and the metal ball will rotate in the fixed seat sleeve under the rotation traction force. At this time, the conductive telescopic set is in a contracted state under the rotation traction force, and the metal ball rotates along the inner wall of the fixed seat sleeve made of insulating material with the metal fixing ring. The uninterrupted rotation prevents the conductive telescopic rod and the metal ball from entering the contact hole and contacting the inner contact bump on the conductive ring of the external power source. When the pre-stored stamping plates in the material storage frame are used up or the material plates are transported and loaded at a slow speed or cannot be loaded continuously from beginning to end, the traction wheel cannot drive the trigger shaft and the metal fixing ring to rotate, and the rebound force of the conductive spring causes the conductive telescopic rod and the metal ball to enter the contact hole and contact the inner contact protrusion on the external power conductive ring, so that the double-headed power conductive rod is connected with the double-headed output conductive rod, and the buzzer alarm is powered on and makes a sound to remind the staff to realize the alarm.

[0022] The beneficial effects of the present invention are:

[0023] (1) The present invention pre-stores multiple groups of stamping material plates through a material storage frame, and uses a main feeding motor and an auxiliary feeding motor. The two groups of motors drive the feeding hoop to move, and use the friction between the material plates to move the bottom layer of material plates to the conveyor belt to achieve automatic feeding. This feeding method eliminates the need for manual feeding by staff, improves efficiency and reduces the risk of manual operation.

[0024] (2) The present invention drives the driving shaft to rotate through the driving wheel and driving belt on the transport motor, and the driving shaft drives the transport belt to move to transport the material sheet. The motor speed in the loading and transporting process is set so that the transport belt loads the material sheet and moves it to the stamping platform for subsequent continuous stamping. The material sheet can be discharged head to tail in cooperation with the loading mechanism, thereby further improving the overall processing efficiency of the device.

[0025] (3) The present invention drives the traction shaft to rotate when the conveyor belt transfers the material sheet to the loading seat and contacts the traction wheel. The traction shaft drives the trigger cam at the other end of the trigger shaft to rotate through the coupling. The trigger cam rotates through the cam traction rod to drive the trigger piston to slide back and forth in the piston sleeve. By controlling the speed of the reducer and the transport motor, when the traction wheel travels through the stamping range of a group of material sheets, the trigger cam can be set to rotate just one circle, thereby completing a lifting movement of the trigger piston. When the trigger piston moves to the highest point, it contacts the inching switch. The switch starts the stamping mechanism to complete a stamping operation, thereby realizing continuous operation.

[0026] (4) The present invention is fixedly connected to the trigger shaft by a metal fixing ring so as to rotate accordingly. When the trigger shaft is at a normal speed, the traction force generated by the rotation causes the conductive telescopic rod to overcome the resilience of the conductive spring and partially retract into the conductive sleeve. The metal ball at the other end of the conductive telescopic rod will roll along the inner wall of the fixed seat sleeve in the ball movable groove, further preventing the metal ball from entering the contact hole and contacting the inner contact protrusion on the conductive ring of the external power source, thereby making the two groups of conductive rods unable to be connected, that is, the buzzer alarm cannot be powered on to trigger the alarm. On the contrary, when the speed is too low or stops rotating, the conductive telescopic rod can enter the contact hole through elastic force and contact the inner contact protrusion on the conductive ring of the external power source, thereby powering on the buzzer alarm to trigger the alarm, so as to remind the staff that the material plate is insufficient or the production line has a fault.

[0027] (5) The present invention uses hydraulic equipment to push the upper gasket mold downward to contact the lower gasket mold, and punches the material plate once through the concave engagement of the mold. The gasket formed by punching will be discharged into the collection unit through the discharge seat. The remaining space of the material plate will be cut off when passing through the cutting mold during the continuous pushing process, and will be introduced into the collection box through the material guide seat for collection. When the stamping is completed, the control unit controls the mold to reset, and triggers the stamping process accurately and continuously through the stroke method.

[0028] In summary, the present invention has the advantages of high automation, continuous stamping and high production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

The metal fixing ring 504 is made of metal and is fixedly connected to the trigger shaft 406, so that it can rotate with the trigger shaft 406 when it rotates. When the trigger shaft 406 is at a normal speed, the traction force generated by the rotation makes the conductive telescopic rod 514 overcome the resilience of the conductive spring 515 and partially retract into the conductive sleeve 513, and the metal ball 516 at the other end will move along the fixed ball groove 517. The inner wall of the fixed seat sleeve 501 rolls, further preventing the metal ball 516 from entering the contact hole 509 and contacting the inner contact protrusion 511 on the external power conductive ring 510, thereby making the two sets of conductive rods unable to be connected, that is, the buzzer alarm 507 cannot be powered on to trigger the alarm; conversely, when the rotation speed is too low or stops rotating, the conductive telescopic rod 514 can enter the contact hole 509 through elastic force and contact the inner contact protrusion 511 on the external power conductive ring 510, thereby the buzzer alarm 507 is powered on to trigger the alarm, so as to remind the staff that there is insufficient material plate or a fault in the production line.

When the switch is triggered, the hydraulic equipment 606 starts to drive the upper gasket mold 605 to move downward along the two sets of guide rods 608 to contact the lower gasket mold 604 to realize stamping of the material plate.

[0070] A gasket stamping process for an electric vehicle gearbox, the process comprising the following steps:

[0071] Step 1: Loading process, multiple groups of stamping material plates 303 of a certain size are placed in the material storage frame 302 for storage. When loading, the electric telescopic rod 311 is energized from bottom to top, and the electric telescopic rod 311 pushes the telescopic baffle 307 to move along the telescopic slide rail 309 and enter the material storage frame 302, so as to support the material plates loaded from above. During processing, the telescopic baffle 307 is partially retracted to make the stamping material plates 303 contact with the main loading roller 312, and the main loading motor 314 and the auxiliary loading motor 315 are started at the same time. The two groups of motors drive the loading hoop 317 to move, and the friction between the material plates is used to move the bottom layer of the material plates to the conveyor belt 203;

[0072] Step 2: Transport process, power on the transport motor 207, the transport motor 207 drives the drive shaft 205 to rotate through the drive wheel 208 and the drive belt 209, and the drive shaft 205 drives the transport belt 203 to move to transport the material sheet, and the motor speed in the loading and transport process is set so that the material sheet on the transport belt 203 is in contact with each other and moves to the stamping platform 1 for subsequent continuous stamping;

[0073] Step 3: triggering process, when the material plate is transferred to the loading seat 610 at one end of the lower gasket mold 604 through the conveyor belt 203, the material plate will contact with the traction wheel 403, and the friction between the material plate and the plate body will drive the traction shaft 402 to rotate, and the traction shaft 402 drives the other end of the trigger shaft 406 to rotate through the coupling 407. The trigger cam 410 decelerated by the reducer 409 rotates, and the trigger cam 410 rotates through the cam traction rod 411 to drive the trigger piston 413 to reciprocate and slide in the piston sleeve 412. Through the control of the speed of the reducer 409 and the transport motor 207, when the traction wheel 403 travels through the stamping range of a group of material plates, the trigger cam 410 can be set to rotate just one circle, thereby completing a lifting movement of the trigger piston 413. When the trigger piston 413 moves to the highest point, it contacts the inching switch 415, and the switch starts the stamping mechanism 6 to complete a stamping operation to achieve continuous operation;

[0074] Step 4: When the stamping process and the switch are triggered, the hydraulic equipment 606 starts to push the upper gasket mold 605 downward through the output rod to contact the lower gasket mold 604, and the material plate is stamped once through the concave engagement of the mold. During stamping, the formed gasket will fall from the holes on the lower gasket mold 604 and the bottom mold seat 602, and then be guided to the collection unit through the material lowering seat 611. The spare part of the material plate will be cut off when passing through the cutting mold 607 during the continuous pushing process, and will be introduced into the collection box 613 through the material guide seat 612 for collection. When the stamping is completed, the control unit controls the mold to reset, and triggers the stamping process accurately and continuously through the stroke mode;

[0075] Step 5: Alarm process. When the material plate is normally loaded and stamped, the metal fixing ring 504 will rotate with the trigger shaft 406. During the rotation, the three sets of conductive telescopic sets consisting of the conductive sleeve 513, the conductive telescopic rod 514, the conductive spring 515 and the metal ball 516 will rotate in the fixed seat sleeve 501 under the rotational traction force. At this time, the conductive telescopic set is in a contracted state under the rotational traction force, and the metal ball 516 rotates along the inner wall of the fixed seat sleeve 501 made of insulating material with the metal fixing ring 504. The uninterrupted rotation prevents the conductive telescopic rod 514 and the metal ball 516 from entering the contact hole 509 and contacting the contact inner protrusion 511 on the external power conductive ring 510. When the pre-stored stamping sheet 303 in the material storage frame 302 is used up or the material sheet transportation and loading speed is slow or the material cannot be loaded continuously from beginning to end, the traction wheel 403 cannot drive the trigger shaft 406 and the metal fixing ring 504 to rotate, and the rebound force of the conductive spring 515 makes the conductive telescopic rod 514 and the metal ball 516 enter the contact hole 509 and contact the contact inner protrusion 511 on the external power conductive ring 510, so that the double-headed power conductive rod 518 is connected with the double-headed output conductive rod 506, and the buzzer alarm 507 is powered on and makes a sound to remind the staff to realize the alarm.

Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
