The three groups of brush heads corresponding to the three lifting plates are used alternately.

[0026] The present invention provides a precision stamping die for sheet metal parts, which has the following beneficial effects:

[0027] 1. For this precision stamping die for sheet metal parts, by setting a stamping mechanism, the sheet metal part is stamped and the stamping head is wiped and cleaned. When stamping the plane of the sheet metal part to change the plane shape, since the stamping head keeps working and is always in the die, impurities are on the outer surface of the stamping head. It is easy to have impurities at the contact position between the stamping head and the sheet metal part, resulting in a poor stamping effect of the sheet metal part.

[0028] 2. For this precision stamping die for sheet metal parts, by setting a control component, during the process of the wiping plate cleaning the bottom of the stamping head, most of the impurities fall onto the second arc-shaped plate and the connecting plate at the bottom. With the opening of the first blower, the impurities on the second arc-shaped plate are gradually sucked into the first air inlet pipe and the first external pipeline. Most of the impurities falling from above are on the viscous rods on the connecting plate. In this way, the bottom of the stamping head is frictionally cleaned and most of the falling impurity debris is collected.

[0029] 3. For this precision stamping die for sheet metal parts, by setting a processing mechanism and a cleaning component, by controlling the stroke of the electric push plate, the feeding and discharging of the lower die and the sheet metal part can be completed. At the same time, as the sheet metal part is fed, the brush heads are in contact with the upper surface of the sheet metal part to clean the upper surface of the sheet metal part. The three groups of brush heads corresponding to the three lifting plates are used alternately to avoid the existence of impurity particles on the upper surface of the sheet metal part, which affects the stamping work.

[0030] 4. For this precision stamping die for sheet metal parts, by setting a limiting mechanism and a suction component, by controlling the position of the cross plate, the fixing and releasing of the lower die are controlled. When it is necessary to fix the position of the lower die, the cross plate is in the bottom plate. Since the cross plate is connected to the bottom plate and through holes are opened at the top of the cross plate, the lower die can be sucked at the bottom to reinforce the lower die. When it is necessary to release the lower die, the cross plate is separated from the bottom plate to facilitate the discharging of the lower die and the sheet metal part.

Detailed Description of the Invention

[0040] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are given for purposes of illustration and description, and are not exhaustive or limit the present invention to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles of the present invention and its practical applications, and to enable those of ordinary skill in the art to understand the present invention and design various embodiments with various modifications suitable for specific purposes.

[0041] As Figures 1-8 shown, the present invention provides a technical solution, including:

[0042] A mold 1, with a chute 202 opened inside the mold 1, a circular channel opened inside the mold 1, and a first arc plate 7 installed on the top of the mold 1. There are two first arc plates 7, which are symmetrically arranged. The feeding and discharging operations of the sheet metal part are both carried out at the bottom of the circular channel, while the stamping operation of the sheet metal part is in the circular channel, so as to separate the feeding and discharging area from the stamping area, and reduce the dust and impurities brought to the stamping head 201 due to the feeding and discharging operations.

[0043] A hydraulic cylinder 3, which is installed on the top of the mold 1;

[0044] A stamping mechanism 2, which is arranged inside the mold 1. The stamping mechanism 2 includes a sliding member 203 and a stamping head 201. A first push rod 204 is installed outside the sliding member 203, and a wiping plate 205 is installed outside the first push rod 204. There are three wiping plates 205. When the sliding member 203 drives the wiping plate 205 to move, the wiping plate 205 rubs against the bottom of the stamping head 201, promoting the detachment of the impurities at the bottom of the stamping head 201 from the stamping head 201, avoiding the attachment of impurities to the bottom of the stamping head 201 due to the long-term use of the stamping head 201, and then following the stamping head 201 to contact the sheet metal part, resulting in local deformation or damage of the sheet metal part. The sliding member 203 and the first push rod 204 are used to drive the wiping plate 205 to reciprocate, and the wiping plate 205 cleans the bottom of the stamping head 201 by means of friction cleaning.

[0045] The sliding member 203 is slidably connected inside the chute 202. The sliding member 203 is composed of a sliding plate and a connecting rod. A power system is provided inside the sliding plate. The stamping head 201 is connected to the hydraulic cylinder 3. A limiting mechanism 6 is installed at the bottom of the mold 1. A support plate 4 is installed outside the mold 1, and a processing mechanism 5 is arranged outside the support plate 4. A control component 206 is installed at the bottom of the wiping plate 205.

[0046] Before using the device, adjust the stamping mechanism 2 and clean the stamping head 201. Then adjust the limit mechanism 6 and the processing mechanism 5. Place the sheet metal part in the processing mechanism 5. After the pretreatment by the processing mechanism 5, the sheet metal part gradually enters the limit mechanism 6. After the limit mechanism 6 fixes the sheet metal part, it drives the sheet metal part upward through the circular channel until the sheet metal part is in the circular channel. Then start the hydraulic cylinder 3 to control the stamping head 201 to stamp the sheet metal part. After the stamping work is completed, adjust the limit mechanism 6, and the limit mechanism 6 drives the sheet metal part back to the bottom of the circular channel. By adjusting the processing mechanism 5 and the limit mechanism 6, the discharging work of the sheet metal part is completed.

[0047] The limit mechanism 6 includes:

[0048] The lifting table 601 is installed at the bottom of the mold 1. The top of the lifting table 601 is provided with a bottom plate 602. A chamber is opened inside the bottom plate 602. The top of the bottom plate 602 is provided with a suction assembly 604. The lower mold 605 is placed on the top of the suction assembly 604. The sheet metal part is in the lower mold 605.

[0049] The second air inlet pipe 603 is installed outside the bottom plate 602. The outside of the second air inlet pipe 603 is provided with a second external pipeline, and the second external pipeline is externally connected to a second fan.

[0050] Before using the device, manually connect the second air inlet pipe 603 and the second external pipeline. Control the movement of the lower mold 605 and the sheet metal part through the processing mechanism 5, so that the lower mold 605 and the sheet metal part move in the direction of the suction assembly 604 to limit the positions of the lower mold 605 and the sheet metal part.

[0051] The suction assembly 604 includes:

[0052] The cross groove 6041 is opened inside the bottom plate 602, and a third push rod 6042 is installed inside the cross groove 6041.

[0053] The cross plate 6043 is installed on the top of the third push rod 6042. A through hole 6045 is opened on the top of the cross plate 6043. A communication groove is opened inside the cross plate 6043, and the communication groove communicates with the bottom plate 602.

[0054] The third arc-shaped plate 6044 is installed on the top of the bottom plate 602. There are two third arc-shaped plates 6044, and they are symmetrically arranged. The third arc-shaped plate 6044 is made of rubber material.

[0055] When using the device, the lifting table 601 and the third push rod 6042 are in the initial state. Before feeding or discharging, the third push rod 6042 is activated. The third push rod 6042 drives the cross plate 6043 to move upward. With the processing mechanism 5 driving the lower die 605 and the sheet metal part to move, the lower die 605 gradually contacts the third arc plate 6044 and rubs against one end of the third arc plate 6044 until the lower die 605 is completely on the cross plate 6043. Subsequently, the third push rod 6042 is adjusted to the initial state, and the second blower is adjusted to the air extraction mode. Since the second air inlet pipe 603 is connected to the bottom plate 602, the bottom plate 602 is connected to the cross plate 6043, and a through hole 6045 is opened at the top of the cross plate 6043, the bottom of the lower die 605 is sucked onto the cross plate 6043, thereby fixing the position of the lower die 605.

[0056] Activate the lifting table 601. The lifting table 601 drives the bottom plate 602, the suction assembly 604, the lower die 605, and the sheet metal part to move upward until the sheet metal part is in the circular channel. Activate the hydraulic cylinder 3 to control the punch head 201 to perform stamping processing on the sheet metal part.

[0057] After the work is completed, adjust the lifting table 601 to the initial state to make the sheet metal part return to the bottom of the circular channel. Activate the third push rod 6042. The third push rod 6042 drives the cross plate 6043 to disengage from the bottom plate 602. Under the push of the processing mechanism 5, the discharging work of the sheet metal part and the lower die 605 is completed.

[0058] By controlling the position of the cross plate 6043, the fixing and releasing of the lower die 605 are controlled. When it is necessary to fix the position of the lower die 605, the cross plate 6043 is in the bottom plate 602. Since the cross plate 6043 is connected to the bottom plate 602 and a through hole 6045 is opened at the top of the cross plate 6043, the lower die 605 can be sucked at the bottom to reinforce the lower die 605. When it is necessary to release the lower die 605, the cross plate 6043 disengages from the bottom plate 602, facilitating the discharging work of the lower die 605 and the sheet metal part.

[0059] The control component 206 includes:

[0060] A connecting ring 2061 is installed at the bottom of the wiping plate 205. A first air inlet pipe 2062 is installed inside the connecting ring 2061. A first external pipeline is installed outside the first air inlet pipe 2062. The first external pipeline is externally connected to a first blower. A fixing pipe 2063 is installed outside the first air inlet pipe 2062. The fixing pipe 2063 is arranged inside the mold 1. When the first push rod 204 and the sliding part 203 drive the wiping plate 205 to move, the wiping plate 205 drives the first air inlet pipe 2062 to move in the fixing pipe 2063, and the fixing pipe 2063 limits the position of the first air inlet pipe 2062.

[0061] The second arc-shaped plate 2064 is installed outside the first air inlet pipe 2062. A plug is installed outside the second arc-shaped plate 2064, and a connecting plate 2065 is installed outside the second arc-shaped plate 2064. There are two connecting plates 2065, and they are symmetrically arranged. The connecting plate 2065 is inclined, with a higher edge position and a lower position near the second arc-shaped plate 2064 in the middle. Viscous rods are arranged on the upper surfaces of the two connecting plates 2065. During the movement of the two connecting plates 2065 and the second arc-shaped plate 2064, dust and impurities falling from the wiping plate 205 are sucked and received.

[0062] Before using the equipment, manually install the first air inlet pipe 2062 and the first external pipeline, and turn on the first fan to the exhaust mode. Turn on the power system in the sliding plate, and the sliding plate moves in the sliding groove 202, thereby driving the connecting rod, the first push rod 204, the wiping plate 205, the connecting ring 2061, the first air inlet pipe 2062, the second arc-shaped plate 2064, and the connecting plate 2065 to move. During the movement of the wiping plate 205, it continuously rubs against the bottom of the punching head 201, driving the impurities to break away from the punching head 201. Most of the impurities fall onto the second arc-shaped plate 2064 and the connecting plate 2065 at the bottom. With the opening of the first fan, the impurities on the second arc-shaped plate 2064 are gradually sucked into the first air inlet pipe 2062 and the first external pipeline, and most of the impurities falling from above are on the viscous rods on the connecting plate 2065. In this way, the bottom of the punching head 201 is frictionally cleaned, and most of the falling impurity debris is collected.

[0063] The processing mechanism 5 includes:

[0064] An adjusting bent rod 501 is installed outside the frame plate 4. An electric push plate 502 is installed outside the adjusting bent rod 501. The electric push plate 502 is used to drive the sheet metal part to enter the limiting mechanism 6 from the frame plate 4 and drive the sheet metal part to move out of the mold 1 from the limiting mechanism 6 for discharging work;

[0065] A back plate 503 is arranged outside the mold 1. A second push rod 505 is installed outside the back plate 503, and a cleaning component 506 is installed outside the second push rod 505;

[0066] A fixed frame 504 is installed at the bottom of the back plate 503. The fixed frame 504 is provided with through grooves, and three through grooves are provided.

[0067] Before using the device, manually place the sheet metal part in the lower die 605, and place the lower die 605 in the support plate 4. Turn on the electric push plate 502, and the electric push plate 502 drives the sheet metal part to move from the support plate 4 to the limit mechanism 6. By adjusting the second push rod 505 and the cleaning component 506, during the movement of the sheet metal part, the upper surface of the sheet metal part is cleaned to avoid local damage to the upper surface of the sheet metal part after stamping due to a large amount of impurities on the upper surface of the sheet metal part.

[0068] The cleaning component 506 includes:

[0069] The central plate 5061 is installed outside the second push rod 505, and a semi-ring 5062 is installed outside the central plate 5061, and three semi-rings 5062 are provided;

[0070] The clamping plate 5063 is installed at the bottom of the semi-ring 5062, a lifting plate 5064 is installed at the bottom of the clamping plate 5063, and a brush head 5065 is installed at the bottom of the lifting plate 5064, and multiple brush heads 5065 are provided.

[0071] Before using the device, the second push rod 505 is in the initial state, and the three lifting plates 5064 correspond to the three through grooves in the fixed frame 504. Turn on the three lifting plates 5064 in turn, and the lifting plate 5064 drives the brush head 5065 to move downward. As the electric push plate 502 drives the lower die 605 and the sheet metal part to move, the brush head 5065 contacts the upper surface of the sheet metal part to clean the upper surface of the sheet metal part, and the three groups of brush heads 5065 corresponding to the three lifting plates 5064 are used in turn. And after use, turn on the second push rod 505, and the second push rod 505 drives the three groups of brush heads 5065 away from the support plate 4, and the brush heads 5065 can be manually cleaned or replaced uniformly.

[0072] Working principle: Before using the device, manually install the first air inlet pipe 2062 and the first external pipeline, and turn on the first fan to the exhaust mode. Turn on the power system in the sliding plate, and the sliding plate moves in the chute 202, thereby driving the connecting rod, the first push rod 204, the wiping plate 205, the connecting ring 2061, the first air inlet pipe 2062, the second arc-shaped plate 2064 and the connecting plate 2065 to move. During the movement of the wiping plate 205, it continuously rubs against the bottom of the stamping head 201, driving the impurities to separate from the stamping head 201. Most of the impurities fall on the second arc-shaped plate 2064 and the connecting plate 2065 at the bottom. As the first fan is turned on, the impurities on the second arc-shaped plate 2064 are gradually sucked into the first air inlet pipe 2062 and the first external pipeline, and most of the impurities falling from above are on the viscous rods on the connecting plate 2065.

[0073] Before using the device, the second push rod 505 is in the initial state. The three lifting plates 5064 correspond to the three through slots in the fixed frame 504. Manually place the sheet metal part in the lower die 605, and then place the lower die 605 on the support plate 4. Turn on the electric push plate 502, and the electric push plate 502 drives the lower die 605 and the sheet metal part to move from the support plate 4 to the limiting mechanism 6. By adjusting the second push rod 505 and the cleaning component 506, turn on the three lifting plates 5064 in turn. The lifting plate 5064 drives the brush head 5065 to move downward. As the electric push plate 502 drives the lower die 605 and the sheet metal part to move, the brush head 5065 contacts the upper surface of the sheet metal part, and the upper surface of the sheet metal part is cleaned. The three groups of brush heads 5065 corresponding to the three lifting plates 5064 are used in turn. During the movement of the sheet metal part, the upper surface of the sheet metal part is cleaned to avoid damage to the local position of the upper surface of the sheet metal part after stamping due to a large amount of impurities on the upper surface of the sheet metal part.

[0074] Before using the device, manually connect the second air inlet pipe 603 to the second external pipeline. Control the movement of the lower die 605 and the sheet metal part through the processing mechanism 5, so that the lower die 605 and the sheet metal part move in the direction of the suction component 604 to limit the positions of the lower die 605 and the sheet metal part.

[0075] When using the device, the lifting table 601 and the third push rod 6042 are in the initial state. Before feeding or discharging, turn on the third push rod 6042. The third push rod 6042 drives the cross plate 6043 to move upward. As the electric push plate 502 in the processing mechanism 5 drives the lower die 605 and the sheet metal part to move, the lower die 605 gradually contacts the third arc plate 6044 and rubs against one end of the third arc plate 6044 until the lower die 605 is completely on the cross plate 6043. Then adjust the third push rod 6042 to the initial state and adjust the second blower to the exhaust mode. Since the second air inlet pipe 603 is connected to the bottom plate 602, the bottom plate 602 is connected to the cross plate 6043, and a through hole 6045 is opened at the top of the cross plate 6043, the bottom of the lower die 605 is sucked on the cross plate 6043, thereby fixing the position of the lower die 605.

[0076] Turn on the lifting table 601. The lifting table 601 drives the bottom plate 602, the suction component 604, the lower die 605 and the sheet metal part to move upward until the sheet metal part is in the circular channel. Turn on the hydraulic cylinder 3 to control the punch head 201 to perform stamping on the sheet metal part.

[0077] After the work is completed, adjust the lifting table 601 to the initial state to make the sheet metal part return to the bottom of the circular channel. Turn on the third push rod 6042. The third push rod 6042 drives the cross plate 6043 to separate from the bottom plate 602. Under the push of the electric push plate 502 in the processing mechanism 5, the discharging work of the sheet metal part and the lower die 605 is completed.
