Description

Technical Field

[0001] The invention relates to the field of automobile parts processing, in particular to a die punching device for automobile parts production. Background Art

The patent uses the ejector rod on the outer surface of the lower die to push the stamped plate on the lower die, so as to achieve rapid demoulding of the stamped part and improve the overall stamping efficiency of the equipment. At the same time, the debris in the lower die and the stamped part are separated from the lower die by the rotation of the lower die, so as to clean the debris in the lower die and ensure the stamping accuracy of subsequent metals; however, it is impossible to load the next metal plate while unloading the stamped part, and its stamping efficiency is limited; the patent with publication number CN113013703A in the prior art discloses a multi-station rotary end The sub-pressing machine head is improved by a rotating seat rotatably set on the machine table and a plurality of workstations set on the rotating seat and rotatable with the rotating seat. However, stamping is to stamp the metal sheet into a desired shape by applying a large downward pressure.

[0033] It also includes a positioning cone head 116; a positioning cone head 116 is provided at the pipe mouth of each blowing pipe 115. When the stamping die is installed on the mounting groove of the mounting die 7, the stamping die is positioned by inserting the positioning cone head 116 into the air hole of the stamping die to ensure that the stamping die can be accurately installed in the mounting groove of the mounting die 7, thereby ensuring the subsequent stamping accuracy, and then the stamping die is fixed by bolts through the bolt holes of the mounting die 7.

[0034] It also includes a sealing ring 101 ; a sealing ring 101 is fixedly connected in the insertion hole 801 of each limiting block 8 ; and a sealing groove 1101 is formed in each limiting rod 11 .

[0035] It also includes springs 121 and a push plate 122 ; the mounting plate 3 is fixedly connected to a plurality of springs 121 ; all the springs 121 are each commonly fixedly connected to a push plate 122 , and the push plate 122 is in contact with the punch head 4 .

[0036] It also includes an electric telescopic rod 131, a movable plate 132, a delivery pipe 133 and an oil injection pipe 134; the installation platform 1 is fixedly connected to two electric telescopic rods 131; each telescopic part of the electric telescopic rod 131 is fixedly connected to a movable plate 132, and the two movable plates 132 are respectively located on the left and right sides of the installation mold 7; each movable plate 132 is fixedly connected to a delivery pipe 133, and the delivery pipe 133 is connected to an external delivery mechanism; each delivery pipe 133 is connected to a plurality of oil injection pipes 134, and the oil injection pipes 134 are arranged to be inclined downward.

[0037] It also includes an electric telescopic rod 135 and an adjustment plate 136; the front and rear sides of each movable plate 132 are each fixedly connected to an electric telescopic rod 135; the telescopic portion of each electric telescopic rod 135 is each fixedly connected to an adjustment plate 136, and the adjustment plate 136 slides on the slide groove of the movable plate 132.

[0038] Before the stamping work is carried out, the corresponding stamping die is manually placed in the mounting groove of the mounting die 7, and the installed stamping die is fixed by bolts through the bolt holes. At the same time, in the process of placing the stamping die in the mounting groove, the air hole of the stamping die is aligned with the positioning cone head 116. When the stamping die is placed in the mounting groove, the positioning cone head 116 is inserted into the air hole of the stamping die, and the positioning cone head 116 is used to assist in the installation of the stamping die, so as to facilitate the proofreading and installation of the stamping die. After completing the installation of one stamping die, the rotating rod 6 and the mounting die 7 are driven by the control motor 5 to rotate 180 degrees, so that the other mounting groove of the mounting die 7 is rotated to the top, and then the same operation is performed to install another stamping die in the other mounting groove of the mounting die 7. After completion, the corresponding stamping head 4 is manually installed on the mounting plate 3.

[0039] When stamping metal sheets, the metal sheets are first placed manually on the surface of the stamping die on the mounting groove, and then the hydraulic telescopic rod 2 is controlled to drive the mounting plate 3 and the punching head 4 to move downward, and the punching head 4 applies pressure to the placed metal sheets to stamp them into the required stamping parts. Then the punching head 4 is controlled to move up and reset, and then the motor 5 is controlled to drive the rotating rod 6 and the mounting die 7 to rotate 180 degrees, and the stamping die is rotated downward, the formed stamping parts are demolded and the debris generated in the stamping die is poured out, so as to realize automatic demolding and automatic cleaning of the stamping, and improve the overall stamping efficiency; the stamped parts after demolding fall through the blanking hole 01 of the mounting platform 1, and only the corresponding collection container needs to be placed manually under the blanking hole 01.

[0040] However, the mounting die 7 is connected by rotation through the rotating rod 6, and the punch head 4, when working, stamps the metal sheet into the desired shape by applying a large downward pressure. During the stamping process, the applied pressure acts entirely on the rotating rod 6, which is easy to damage it. In addition, during the stamping process, the mounting die 7 is prone to rotation, which affects the stability of the stamping and further affects the stamping accuracy of the stamped part. At the same time, during the rotary demoulding and cleaning process, it is still necessary to wait for the demoulding and cleaning to be completed before the next stamping can be performed, and the stamping efficiency is not high. Therefore, when the metal sheet is placed manually, the hydraulic push rod 9 is controlled to drive the support plate 1 0 and the limit rod 11, as well as other connected parts move upward, the limit rod 11 moves upward and is inserted into the socket 801 of the limit block 8, and when the support plate 10 moves up and contacts the mounting die 7, it stops moving, and the support plate 10 supports the bottom of the mounting die 7. When the subsequent punch head 4 presses down to work, the support plate 10 applies a supporting force to the bottom of the mounting die 7 to relieve the pressure on the rotating rod 6 during stamping and avoid damage to it, and the limit rod 11 is inserted into the limit block 8 to limit the entire mounting die 7 to prevent the mounting die 7 from rotating during the stamping process, which affects the stamping accuracy of the stamped parts.

[0041] In addition, a stamping die is installed in the mounting grooves on the upper and lower sides of the mounting die 7. When the stamping head 4 completes the stamping and moves up to reset, the hydraulic push rod 9 is controlled to drive the support plate 10 and the limit rod 11 to move down and reset. After the two are reset at the same time, the motor 5 is controlled to drive the rotating rod 6 and the mounting die 7 to rotate 180 degrees. The mounting die 7 rotates, driving the stamping die in the upper mounting groove and the stamped stamped part to rotate to the lower side, and driving the stamping die in the lower mounting groove to rotate to the upper side. Then, the next metal sheet is placed manually on the surface of the rotating stamping die, and then the hydraulic telescopic rod 2 is controlled to drive the stamping head 4 to move downward to stamp the next metal sheet, and the stamping head 4 moves downward to perform stamping on the next metal sheet. During the stamping process, the above operation is repeated, and at the same time, the hydraulic push rod 9 is controlled to drive the support plate 10 and the limit rod 11 to move upward, so that when the punch head 4 is punching again, the support plate 10 and the limit rod 11 can support and limit the installation mold 7, so that the installation mold 7 remains stable during the stamping process, thereby ensuring the stamping accuracy of the stamped parts; and when the support plate 10 supports the bottom of the installation mold 7, the limit rod 11 is inserted into the limit block 8 to limit the installation mold 7, and the punch head 4 moves downward for stamping, while the external pump is controlled to pass the gas into the ventilation pipe 111, and the gas in the ventilation pipe 111 passes through the gas supply pipe 112, the jack 801 and the air inlet pipe 113 in turn into the round tube 114, and is blown out from the blowing pipe 115. 5. Blow gas from the air hole of the stamping die into the space between the stamping die and the stamping part. As the amount of gas introduced gradually increases, the stamping part in the stamping die is ejected, and the automatic demoulding of the stamping part is completed. In addition, a sealing ring 101 is provided in the plug hole 801. When the limit rod 11 is inserted into the plug hole 801, the sealing ring 101 is simultaneously inserted into the sealing groove 1101 of the limit rod 11, thereby sealing the connection between the gas pipe 112 and the air inlet pipe 113, ensuring that the gas pipe 112 can pass all the gas into the air inlet pipe 113, preventing the gas introduced into the gas pipe 112 from leaking from the limit rod 11 and the plug hole 801, reducing the pressure of the gas blown out of the blowing pipe 115, and affecting the subsequent demoulding. After the punch head 4 completes the second punching, the punch head 4 is controlled to The pressure head 4 is reset, and the support plate 10 and the limit rod 11 are synchronously controlled to reset. The above operation is then repeated to carry out the stamping work. In this way, during stamping, the mounting die 7 can be supported and limited by the support plate 10 and the limit rod 11 to prevent the mounting die 7 from rotating during the stamping process, which affects the stamping accuracy of the stamped parts. In addition, a stamping die is installed in the mounting grooves on the upper and lower sides of the mounting die 7. By rotating and switching the mounting die 7, the stamped parts formed by the previous stamping can be automatically demolded synchronously during the support and limitation and the next stamping process, so that the stamping and demolding are carried out synchronously, and the next stamping can be carried out without waiting for the demolding of the stamped parts, which greatly improves the overall stamping efficiency.

[0042] It should be noted that in the process of the hydraulic telescopic rod 2 driving the mounting plate 3 and the punch head 4 to move downward for stamping, the mounting plate 3 simultaneously drives the spring 121 and the push plate 122 to move downward. When the punch head 4 moves downward to contact the stamping die for stamping, the push plate 122 simultaneously contacts the mounting die 7, and as the punch head 4 continues to move downward for stamping, the spring 121 contracts under the extrusion of the mounting die 7. When the punch head 4 completes the stamping and moves upward to reset, as the punch head 4 moves upward, the spring 121 rebounds and resets, and the push plate 122 remains stationary, thereby causing the punch head 4 to move upward from the middle of the push plate 122. At this time, the push plate 122 scrapes the surface of the punch head 4 and limits the stamped parts to be formed, to prevent the stamped parts from adhering to the punch head 4 and affecting subsequent stamping and demolding.

[0043] In addition, during the stamping process of the metal sheet, a large friction force will be generated between the sheet and the die. The generated friction can easily cause the die to wear and affect the surface quality of the stamped part after forming. Therefore, during the stamping process of the metal sheet, before the metal sheet is manually placed on the stamping die, the external conveying mechanism is controlled to convey the lubricating liquid into the conveying pipe 133 and spray it out from the oil spray pipe 134 to spray the lubricating liquid on the surface of the stamping die on the mounting groove. Then, the metal sheet is manually placed on the surface of the stamping die, and the lubricating liquid is sprayed on the stamping die through the oil spray pipe 134 to reduce the friction between the metal sheet and the die, thereby improving the die life and the surface quality of the stamped part. At the same time, it is taken into consideration that when the metal sheet is manually placed on the surface of the stamping die, it cannot be guaranteed that the placed metal sheet can The metal sheet cannot be placed accurately, and there is a slight skew, which affects the stamping accuracy of the subsequent stamping parts. Therefore, after the metal sheet is placed, the electric telescopic rod 131 is controlled to drive the movable plate 132 and other connected parts to move toward the metal sheet, and the two movable plates 132 move toward each other to clamp the placed metal sheet and adjust and correct it in the left and right directions, and the oil spray pipe 134 is controlled to spray lubricating liquid on the surface of the metal sheet, and then the electric telescopic rod 135 is controlled to drive the adjustment plate 136 to move, and the front and rear directions of the metal sheet are adjusted and corrected by the adjustment plate 136. In this way, in the process of spraying lubricating liquid by the oil spray pipe 134, the position of the metal sheet can be adjusted and corrected by the movable plate 132 and the adjustment plate 136, thereby ensuring subsequent stamping.

[0044] Example 2

[0045] On the basis of Example 1, Figure 4 and Figure 8As shown, it also includes an electric push rod 201 and a top plate 202; two electric push rods 201 are fixedly connected to the outer surface of the mounting groove of each mounting mold 7; each telescopic part of each electric push rod 201 is detachably connected to a top plate 202, the top plate 202 penetrates the mounting mold 7, and the stamping mold fixed in the mounting groove has a connecting hole corresponding to the top plate 202. Initially, the top plate 202 is located at the connecting hole of the stamping mold, and the two perfectly fit together to form a complete mold surface. When the air blowing pipe 115 cannot demould the stamping part, it means that the stamping part is damaged, and the air leakage causes the air pressure to be insufficient to push the damaged stamping part. The top plate 202 is inserted from the connecting hole of the stamping mold to push the stamping part in the stamping mold, so that the damaged stamping part in the stamping mold is deformed and separated from the stamping mold, and demoulded. By setting the top plate 202 to be detachable, the mold and the top plate 202 can be replaced according to different stamping products.

[0046] It also includes a gas hose 203; the top plate 202 is set as a hollow structure, the top plate 202 is connected to the gas hose 203, and the gas hose 203 is connected to an external pump; a plurality of air outlet holes 20201 are opened on the four sides of the top plate 202.

[0047] The air outlet hole 20201 is set to be inclined, which can increase the blowing range of the air outlet hole 20201 to the inside of the stamping mold and improve the cleaning effect on the inside of the stamping mold.

[0048] On the basis of the above-mentioned embodiment 1, lubricating liquid is sprayed on the surface of the mold and the plate, so that the debris generated by the subsequent stamping will be absorbed by the lubricating liquid, and the stamping mold installed in the rotating inverted mounting mold 7 cannot pour it out and clean it, thereby affecting the stamping accuracy of the subsequent stamping parts; therefore, an infrared sensor is provided at the blanking hole 01, and when the stamped part after demoulding falls through the blanking hole 01, the fallen stamped part can be sensed by the provided infrared sensor; when the air blow pipe 115 blows to demould, and the infrared sensor detects the falling of the stamped part, then the electric push rod 201 is quickly controlled to drive the top plate 202 to move toward the center of the mounting mold 7, and the end of the top plate 202 with the air outlet 20201 passes through the punching The connecting hole of the stamping die is connected, so that the air outlet hole 20201 is located in the stamping die. During this process, the external pump is controlled to pass the gas into the air hose 203 and blow it out from the air outlet hole 20201. The inside of the stamping die is blown through the air outlet hole 20201 to blow off the debris attached to the inside, thereby fully cleaning the debris generated by the stamping and improving the stamping accuracy of subsequent stamping; and, when the stamping head 4 completes the stamping and the stamping head 4, the support plate 10 and the limit rod 11 are reset, the top plate 202 is synchronously controlled to be reset, so that during the stamping process of the stamping head 4, the stamping, demoulding and cleaning can be carried out simultaneously, and the next stamping can be carried out without waiting, which greatly improves the overall stamping efficiency.

[0049] Considering that when stamping thinner metal sheets, there is a possibility of stamping damage, which causes the stamped parts to be damaged. When the air blow pipe 115 blows gas into the space between the stamping die and the stamped parts for demoulding, the gas will flow out from the damaged area, and it is impossible to ensure that the stamped parts can be automatically demoulded, resulting in the inability to perform the overall stamping and demoulding synchronously, affecting the overall stamping efficiency. Therefore, when the air blow pipe 115 is blowing to demould, if the infrared sensor fails to detect the falling of the stamped parts, it means that the air blow pipe 115 fails to achieve automatic demoulding of the stamped parts, that is, the stamped parts are damaged. When there are damaged stamping parts still remaining in the stamping die, the electric push rod 201 is continued to be controlled to drive the top plate 202 to move further toward the inside of the stamping die through the connecting hole of the stamping die, and the stamping parts remaining in the stamping die are pushed through the top plate 202, so that the damaged stamping parts are deformed and separated from the stamping die, and demolded. The top plate 202 is controlled to move the stamping parts repeatedly to separate the stamping parts from the stamping die, and the blowing of the air pipe 115 and the air outlet 20201 is coordinated to completely demold the stamping parts, thereby ensuring that the overall stamping, demolding and cleaning are carried out simultaneously.

[0050] The above is only a preferred embodiment of the present invention.
