Description

Technical Field

[0001] This utility model relates to the field of punching technology, and in particular to a multifunctional metal product punching press. Background Technology

[0002] Punch presses are mainly used to process sheet metal in various ways using dies, such as blanking, punching, and forming. When punch presses process metal products, dust may be present on the surface of the metal products, and dust particles can interfere with the forming of the metal products. At the same time, iron filings may fall off the metal products during the stamping deformation process. Iron filings left on the stamping die can also affect subsequent stamping. These impurities and waste chips usually need to be removed manually, which is quite troublesome and may also cause danger.

[0003] The existing technology CN214022856U discloses a punch press for metal products that facilitates the removal of waste chips. It includes a top seat and a base. The top seat is located above the base, and an upper die is fixedly connected to the lower end of the top seat. When the metal product is placed onto the lower die, the machine tool's power structure pushes the top seat downwards, causing the top seat to move the upper die downwards to punch the metal product. By activating the machine tool's transmission structure fixed to the reciprocating screw, the reciprocating screw rotates. Since the chip removal rod is threadedly connected to the reciprocating screw, the reciprocating screw drives the chip removal rod to move to the left, activating the suction structure connected to the connecting hose. As the chip removal rod moves to the left, the waste chips on the lower die are sucked into the chip removal groove and then removed through the connecting hose. When the chip removal rod reaches the far right, due to the reciprocating nature of the screw, the chip removal rod moves to the left, further sucking up the waste chips on the lower die and cleaning them. This solves the problem of inconvenient cleaning of waste chips generated during punching.

[0004] However, when using the above method, the upper die applies pressure to the metal product to plastically deform it and obtain the required shape and precision. However, the reaction force caused by the force applied to the metal product during processing is absorbed by the punch press itself, and the vibration force will damage the punch press, thereby reducing the service life of the punch press. Utility Model Content

[0005] The purpose of this invention is to provide a multifunctional metal product punching press that can reduce vibration during the punching of metal products, prevent damage to the punching press due to excessive vibration, and improve the service life of the punching press.

[0006] To achieve the above objectives, this utility model provides a multifunctional metal product punching press, including an upper die and a stamping assembly. The stamping assembly includes a lifting component, a base, a guide rod, a sliding plate, a shock-absorbing spring, a support component, and a lower die.

[0007] The lifting component is disposed on the side of the upper mold; the base is disposed on the side of the lifting component; the guide rod is fixedly connected to the base and located inside the base; the sliding plate is slidably connected to the guide rod and located on the side of the guide rod; one end of the shock-absorbing spring is fixedly connected to the base and the other end is fixedly connected to the sliding plate and located between the base and the sliding plate; the support component is disposed on the top of the sliding plate; the lower mold is disposed on the top of the support component.

[0008] The lifting component includes a linear drive element and a mounting plate; the linear drive element is disposed on the side of the base, and the mounting plate is disposed between the linear drive element and the upper mold.

[0009] The supporting component includes a sliding seat, a support plate, a shock-absorbing pad, and a connecting plate; the sliding seat and the sliding plate are fixedly connected and located on top of the sliding plate; the support plate and the sliding seat are fixedly connected and located on top of the sliding seat; the shock-absorbing pad is located on top of the support plate; the connecting plate and the lower mold are fixedly connected and located between the shock-absorbing pad and the lower mold.

[0010] The supporting component further includes a screw and a nut; the screw is fixedly connected to the connecting plate and passes through the shock-absorbing pad and the supporting plate; the nut is threadedly connected to the screw and is located at the bottom of the screw.

[0011] The supporting component further includes a spring damper; the spring damper is fixedly connected to the base and to the sliding seat, and is located between the base and the sliding seat.

[0012] This utility model discloses a multifunctional metal product punching press. The metal product to be punched is placed on the lower die, and the upper die is driven to move downward by the lifting component, so that the upper die punches the metal product on the lower die. During the punching process, the lower die is subjected to the pressure of the upper die, which drives the support component and the sliding plate to move downward. The sliding plate applies pressure to the shock-absorbing spring, which provides a buffering effect and can reduce vibration when punching the metal product, preventing the punch press from being damaged by excessive vibration and improving the service life of the punch press.

[0019] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0020] Please see Figures 1-4 ,in, Figure 1 This is a schematic diagram of the overall structure of this utility model. Figure 2 This is a structural schematic diagram of the entire utility model from another perspective. Figure 3 This is a cross-sectional view of the entire utility model. Figure 4 This is a structural schematic diagram of the support plate, shock-absorbing pad, connecting plate, screw, and nut of this utility model.

[0021] This utility model provides a multifunctional metal product punching press, including an upper die 101 and a stamping assembly. The stamping assembly includes a lifting component 102, a base 103, a guide rod 104, a sliding plate 105, a shock-absorbing spring 106, a support component 107, and a lower die 108. The lifting component 102 includes a linear drive element 109 and a mounting plate 110. The support component 107 includes a sliding seat 111, a support plate 112, a shock-absorbing pad 113, a connecting plate 114, a screw 115, a nut 116, and a spring shock absorber 117. The aforementioned solution can reduce vibration during the stamping of metal products, prevent the punching press from being damaged by excessive vibration, and improve the service life of the punching press.

[0022] In this specific embodiment, the lifting component 102 is disposed on the side of the upper mold 101; the base 103 is disposed on the side of the lifting component 102; the guide rod 104 is fixedly connected to the base 103 and is located inside the base 103; the sliding plate 105 is slidably connected to the guide rod 104 and is located on the side of the guide rod 104; one end of the shock-absorbing spring 106 is fixedly connected to the base 103, and the other end is fixedly connected to the sliding plate 105 and is located between the base 103 and the sliding plate 105; the supporting component 107 is disposed on the top of the sliding plate 105; and the lower mold 108 is disposed on the top of the supporting component 107. The guide rod 104 provides guidance for the shock-absorbing spring 106 and the sliding plate 105. In use, the metal product to be stamped is placed on the lower die 108, and the upper die 101 is driven to move downward by the lifting component 102, so that the upper die 101 stamps the metal product on the lower die 108. During the stamping process, the lower die 108 is subjected to the pressure of the upper die 101, which drives the support component 107 and the sliding plate 105 to move downward. The sliding plate 105 applies pressure to the shock-absorbing spring 106, which provides a buffering effect and can reduce vibration when stamping metal products, preventing the punch press from being damaged by excessive vibration and improving the service life of the punch press.

[0023] The linear drive element 109 is disposed on the side of the base 103, and the mounting plate 110 is disposed between the linear drive element 109 and the upper mold 101. The linear drive element 109 is used to drive the mounting plate 110 and the upper mold 101 to move longitudinally. The linear drive element 109 adopts existing technology, such as a hydraulic cylinder.

[0024] Secondly, the sliding seat 111 is fixedly connected to the sliding plate 105 and is located on top of the sliding plate 105; the support plate 112 is fixedly connected to the sliding seat 111 and is located on top of the sliding seat 111; the shock-absorbing pad 113 is located on top of the support plate 112; the connecting plate 114 is fixedly connected to the lower die 108 and is located between the shock-absorbing pad 113 and the lower die 108. The sliding seat 111, the support plate 112, the shock-absorbing pad 113, and the connecting plate 114 jointly support the lower die 108. During the stamping process, when the lower die 108 is subjected to pressure from the upper die 101, the shock-absorbing pad 113 can provide a buffering effect, which can reduce vibration when stamping metal products and prevent the stamping press from being damaged due to excessive vibration.

[0025] Meanwhile, the screw 115 and the connecting plate 114 are fixedly connected and pass through the shock-absorbing pad 113 and the support plate 112; the nut 116 is threadedly connected to the screw 115 and is located at the bottom of the screw 115. Both the shock-absorbing pad 113 and the support plate 112 are provided with through holes adapted to the screw 115. When installing the shock-absorbing pad 113, first place the shock-absorbing pad 113 on the support plate 112, then place the connecting plate 114 on the shock-absorbing pad 113, and let the screw 115 pass through the shock-absorbing pad 113 and the support plate 112 in sequence. Finally, tighten the nut 116 at the bottom of the screw 115, thereby connecting the support plate 112, the shock-absorbing pad 113, and the connecting plate 114 together. When the shock-absorbing pad 113 needs to be replaced, unscrew the nut 116 from the screw 115, and then remove the connecting plate 114 and the shock-absorbing pad 113 in sequence to replace the shock-absorbing pad 113. This fixing method facilitates the replacement of the shock-absorbing pad 113.

[0026] In addition, the spring damper 117 is fixedly connected to the base 103 and the sliding seat 111, and is located between the base 103 and the sliding seat 111. The spring damper 117 can suppress the oscillation when the damping spring 106 rebounds after absorbing shock, so that the lower mold 108 can quickly maintain stability after the upper mold 101 moves upward after stamping is completed.

[0027] When using this invention, the metal product to be stamped is placed on the lower die 108. The linear drive element 109 drives the mounting plate 110 and the upper die 101 to move downward, so that the upper die 101 stamps the metal product on the lower die 108. During the stamping process, the lower die 108 is subjected to the pressure of the upper die 101, which drives the placement plate, the shock-absorbing pad 113, the support plate 112, the sliding seat 111, and the sliding plate 105 to move downward. The sliding plate 105 applies pressure to the shock-absorbing spring 106. The shock-absorbing spring 106 and the shock-absorbing pad 113 can provide a buffering effect, which can reduce vibration when stamping the metal product, prevent the punch press from being damaged by excessive vibration, and improve the service life of the punch press. After stamping is completed, the linear drive element 109 drives the upper die 101 to move upward, and the lower die 108 moves upward under the action of the damping spring 106. The spring damper 117 can suppress the oscillation when the damping spring 106 rebounds after absorbing shock, so that the lower die 108 can quickly maintain stability after the upper die 101 moves upward after stamping is completed. This application not only sets the damping spring 106 to dampen the machine tool, but also sets the support plate 112, the damping pad 113, the connecting plate 114, the screw 115 and the nut 116 to replace the damping pad 113, which has multiple functions.

[0028] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
