Description

Technical Field

[0001] This invention belongs to the field of automotive parts manufacturing technology, and more specifically, relates to a stamping die for automotive parts manufacturing and its usage method. Background Technology

[0002] Stamping dies are used in the manufacturing of automotive parts mainly because they can efficiently achieve plastic deformation of metal sheets to meet the requirements of complex shapes and high precision. The stamping process applies pressure to the material through the die, causing it to separate or be formed, which significantly improves production efficiency and product consistency, while reducing material waste and processing costs.

[0003] The following problems still exist with the stamping dies currently in use: 1. The upper and lower stamping dies are generally connected to the die frame by screws, which makes it inconvenient to replace the upper and lower stamping dies; 2. They usually lack a limiting structure, which makes the stamping dies prone to shaking after long-term use; 3. When the stamping die makes abnormal noise or there is a safety hazard in the stamping area, the staff cannot press the emergency stop switch in time. Summary of the Invention

[0004] This disclosure relates to a stamping die for manufacturing automotive parts and its usage method. The die includes a drive positioning component, a stamped part, a multi-purpose limiting component, and an emergency stop auxiliary component. When the stamped part needs replacement, a U-shaped limiting pin is inserted into circular grooves b and c, and then the stamped part is moved upwards, facilitating disassembly and installation. Two L-shaped limiting rods restrict the four screws on the drive frame, preventing it from loosening. When abnormal noise occurs during die operation or there is a safety hazard in the stamping area, the operator can automatically press the emergency stop switch while away from the die, ensuring timely activation.

[0014] In another aspect, this disclosure provides a method of using a stamping die for manufacturing automotive parts, comprising the following steps:

[0015] 1) Secure the drive frame with four screws, then connect the control panel to the external power supply;

[0016] 2) Insert the four circular positioning pins into the four positioning slots, and then insert the U-shaped limiting pins into the circular grooves a and b;

[0017] 3) Connect the wristband to the worker's wrist;

[0018] 4) Place the sheet metal to be stamped between the lower forming die and the upper forming die;

[0019] 5) Control the extension or retraction of the output shaft of the electric telescopic rod via the control panel.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The four circular positioning pins and four positioning slots of this invention provide a positioning effect for the lower forming die; the upper forming die can slide up and down along the two circular guide rods, realizing the stamping process of automotive parts;

[0022] In addition, when the control panel controls the output shaft of the electric telescopic rod to extend, the cross-shaped pressing plate drives the upper forming mold to move downward; when the control panel controls the output shaft of the electric telescopic rod to retract, the two return springs a drive the upper forming mold to return upward.

[0023] 2. The drive frame and the lower forming die of this invention can be connected as one unit under the action of the U-shaped limiting pin, preventing the four circular positioning pins from falling off from the four positioning slots; when the U-shaped limiting pin is not connected to the circular groove a and the circular groove b, the control switch is in the unpressed state. At this time, the control panel cannot control the output shaft of the electric telescopic rod to extend, ensuring that the U-shaped limiting pin must be connected to the circular groove a and the circular groove b during the stamping of automotive parts; the setting of the two L-shaped limiting rods restricts the four screws on the drive frame, preventing the drive frame from becoming loose;

[0024] Furthermore, when the stamped part needs to be replaced, the operator first controls the output shaft of the electric telescopic rod to extend through the control panel, so that the lower forming die contacts the upper forming die. Then, the U-shaped limiting pin is inserted into the circular grooves b and c. After that, the output shaft of the electric telescopic rod is controlled to retract through the control panel, and then the stamped part is moved upward, which facilitates the disassembly and installation of the stamped part. The setting of four circular stabilizing balls and two return springs b increases the stability after the U-shaped limiting pin is connected, ensuring the limiting accuracy.

[0025] 3. This invention can connect the worker's wrist to the rectangular mounting frame via a steel wire rope and wrist strap, so that the worker's wrist can drive the rectangular mounting frame and the pressing bar to move forward.

[0026] In addition, when abnormal noise occurs during the operation of the stamping die or there is a safety hazard in the stamping area, the operator can automatically press the emergency stop switch when away from the stamping die, thus realizing the timely activation of the emergency stop switch; due to the setting of the reset spring c, the rectangular mounting frame plays an elastic support role, so that the pressing bar will not activate the emergency stop switch when the stamping die is working normally.

[0050] Its specific function is as follows: Since four circular positioning pins 102 are fixedly installed on the drive frame 101, and four positioning slots 2011 are opened at the bottom of the forming lower die 201, and the four circular positioning pins 102 are inserted into the four positioning slots 2011, the forming lower die 201 is positioned; since two circular guide rods 202 are fixedly installed on the forming lower die 201, and the forming upper die 203 is slidably installed on the two circular guide rods 202, the forming upper die 203 can slide up and down along the two circular guide rods 202, thus realizing the stamping processing of automotive parts;

[0051] Furthermore, since the electric telescopic rod 104 is mounted on the drive frame 101 and the cross-shaped pressing plate 105 is fixedly mounted on the output shaft of the electric telescopic rod 104, when the control panel 400 controls the output shaft of the electric telescopic rod 104 to extend, the cross-shaped pressing plate 105 drives the upper forming mold 203 to move downward; and since the two return springs a204 are sleeved on the outside of the two circular guide rods 202 and the two return springs a204 are located in the lower forming mold 201 and the upper forming mold 203, when the control panel 400 controls the output shaft of the electric telescopic rod 104 to retract, the two return springs a204 drive the upper forming mold 203 to return upward.

[0052] In this embodiment of the disclosure, such as Figure 6 and Figure 8As shown, the multi-purpose limiting component 300 includes: a U-shaped limiting pin 301 and an L-shaped limiting rod 302; the U-shaped limiting pin 301 is inserted into the circular groove a1011 and the circular groove b2012; there are two L-shaped limiting rods 302, and the two L-shaped limiting rods 302 are fixedly installed on the left and right sides of the U-shaped limiting pin 301; the two L-shaped limiting rods 302 are inserted into the two triangular reinforcing brackets 103, and the two L-shaped limiting rods 302 also contact four screws on the drive frame 101; the multi-purpose limiting component 300 also includes: a circular stabilizing ball 303 and a return spring b304; there are four circular stabilizing balls 303, and the four circular stabilizing balls 303 are slidably installed inside the U-shaped limiting pin 301; there are two return springs b304, and the two return springs b304 are installed inside the U-shaped limiting pin 301, and the two ends of the two return springs b304 contact the four circular stabilizing balls 303;

[0053] Its specific function is as follows: Because the U-shaped limiting pin 301 is inserted into the circular groove a1011 and the circular groove b2012, the drive frame 101 and the lower forming mold 201 can be connected as one unit under the action of the U-shaped limiting pin 301, preventing the four circular positioning pins 102 from falling off from the four positioning slots 2011; when the U-shaped limiting pin 301 is not connected to the circular groove a1011 and the circular groove b2012, the control switch 106 is in the unpressed state. At this time, the control panel 400 cannot control the output shaft of the electric telescopic rod 104 to extend, but the control panel 40... The output shaft of the electric telescopic rod 104 can be retracted to ensure that the U-shaped limiting pin 301 is connected to the circular groove a1011 and the circular groove b2012 during the stamping of automotive parts. Since the two L-shaped limiting rods 302 are fixedly installed on the left and right sides of the U-shaped limiting pin 301 and inserted into the two triangular reinforcing brackets 103, and the two L-shaped limiting rods 302 also contact the four screws on the drive frame 101, they play a limiting role on the four screws on the drive frame 101, so that the drive frame 101 will not become loose.

[0054] Furthermore, because the upper forming die 203 has a circular groove c2031 on its rear side, and the circular grooves a1011, b2012, and c2031 are the same size, when the stamped part 200 needs to be replaced, the operator first controls the output shaft of the electric telescopic rod 104 to extend through the control panel 400, so that the lower forming die 201 contacts the upper forming die 203. Then, the U-shaped limiting pin 301 is inserted into the circular grooves b2012 and c2031. After that, the output shaft of the electric telescopic rod 104 is controlled to retract through the control panel 400, and then the stamped part 200 is moved upward, which facilitates the disassembly and installation of the stamped part 200.

[0056] Its specific function is as follows: Since the rear end of the wire rope 505 is fixedly installed on the rectangular mounting frame 501, and the wrist strap 506 is fixedly installed on the front end of the wire rope 505, the worker's wrist can be connected to the rectangular mounting frame 501 through the wire rope 505 and the wrist strap 506; Since the rectangular mounting frame 501 is slidably installed on the drive frame 101, and the pressing bar 502 is fixedly installed on the inner wall of the rectangular mounting frame 501, the worker's wrist can drive the rectangular mounting frame 501 and the pressing bar 502 to move forward.

[0057] Furthermore, because the control panel 400 is equipped with an emergency stop switch 401, and the front end of the pressing bar 502 is a beveled structure, and the pressing bar 502 and the emergency stop switch 401 are on the same plane, when abnormal noise occurs during the operation of the stamping die or there is a safety hazard in the stamping area, the operator can automatically press the emergency stop switch 401 when away from the stamping die, thus achieving timely activation of the emergency stop switch 401. Also, because the return spring c504 is sleeved on the outside of the circular mounting shaft 503, and the return spring c504 is located between the control panel 400 and the rectangular mounting frame 501, it provides elastic support for the rectangular mounting frame 501, so that the pressing bar 502 will not activate the emergency stop switch 401 when the stamping die is working normally.

[0058] This invention provides a method for using a stamping die for manufacturing automotive parts, comprising the following steps:

[0059] 1) Secure the drive frame 101 with four screws, and then connect the control panel 400 to the external power supply;

[0060] 2) Insert four circular positioning pins 102 into four positioning slots 2011 to position the lower mold 201. Then insert U-shaped limiting pins 301 into circular grooves a1011 and b2012.

[0064] The specific usage and function of this embodiment are as follows:

[0065] In use, the drive frame 101 is first fixedly installed using four screws, and then the control panel 400 is connected to an external power source. Four circular positioning pins 102 are inserted into four positioning slots 2011, and then U-shaped limiting pins 301 are inserted into circular grooves a1011 and b2012. The drive frame 101 and the lower forming mold 201 are connected as a unit by the U-shaped limiting pins 301, preventing the four circular positioning pins 102 from falling off from the four positioning slots 2011. When the U-shaped limiting pins 301 are not in contact with the circular grooves a1011 and b2012... When connected at 12, the control switch 106 is in the unpressed state. At this time, the control panel 400 cannot control the output shaft of the electric telescopic rod 104 to extend, ensuring that the U-shaped limiting pin 301 must connect with the circular groove a1011 and the circular groove b2012 during the stamping of automotive parts; the setting of the two L-shaped limiting rods 302 restricts the four screws on the drive frame 101, preventing the drive frame 101 from becoming loose; connect the wristband 506 to the operator's wrist; place the sheet metal to be stamped between the lower forming die 201 and the upper forming die 203; and control the process via the control panel. The control panel 400 controls the extension or retraction of the output shaft of the electric telescopic rod 104; when the control panel 400 controls the extension of the output shaft of the electric telescopic rod 104, the cross-shaped pressing plate 105 drives the upper forming die 203 to move downward; when the control panel 400 controls the retraction of the output shaft of the electric telescopic rod 104, the two return springs a204 drive the upper forming die 203 to return upward; when abnormal noise occurs during the operation of the stamping die or there is a safety hazard in the stamping area, the operator can automatically press the emergency stop switch 401 when away from the stamping die, realizing the timely pressing of the emergency stop switch 401; return spring c50 The setting 4 provides elastic support for the rectangular mounting frame 501, ensuring that the pressing bar 502 will not activate the emergency stop switch 401 under normal working conditions of the stamping die. When the stamped part 200 needs to be replaced, the operator first controls the output shaft of the electric telescopic rod 104 to extend through the control panel 400, so that the lower forming die 201 contacts the upper forming die 203. Then, the U-shaped limiting pin 301 is inserted into the circular groove b2012 and the circular groove c2031. After that, the output shaft of the electric telescopic rod 104 is retracted through the control panel 400, and then the stamped part 200 is moved upward.
