Abstract
Description
Technical Field
[0001] This utility model relates to the field of stamping equipment technology, and in particular to a stamping press for processing automotive parts. Background Technology
[0002] Automotive parts are typically stamped using stamping equipment with stamping dies installed. The stamping equipment then controls the dies to process materials into parts or semi-finished products. For example, Chinese invention patent application CN119857777A discloses a stamping equipment for automotive parts, including a machine body, a slider component, a connecting table, a guide rail component, a worktable, and a stamping die. The machine body supports and connects other components of the stamping press, while the slider component is a component that cooperates with the die. Its up-and-down movement can stamp metal materials into different shapes. The machine body is equipped with other driving components for controlling the up-and-down movement of the slider component, such as transmission components, control components, cylinder components, and lubrication components. The up-and-down movement of the slider component is limited by the guide rail component, and a connecting table is provided below the slider component for fixing the upper die of the mold. Below the connecting table is a worktable, which is fixedly connected to the machine body. The worktable is in a fixed state, and the stamping die is mounted on the worktable.
[0003] Currently, metal coils are commonly used for stamping, requiring stable feeding of the metal coils. Chinese invention patent application CN119972907A discloses a metal coil processing stamping device, including a worktable. A lower die is fixedly connected to the top of the worktable, and an upper die is positioned on top of the lower die. The upper die is fixed to the bottom of a stamping plate, which is fixed to the bottom of a hydraulic rod. The hydraulic rod is driven up and down by the main machine (body). The metal coil is mounted on an uncoiler, which uncoils the coil and levels it using a leveling machine. The coil is then conveyed between the upper and lower dies, and the hydraulic rod drives the stamping plate to rise and fall. The descending stamping plate presses against the upper die, causing it to descend further. The descending upper die then stamps the metal coil. After stamping, the stamping plate rises again. This patent ensures stable feeding of the metal coil through the leveling machine and corresponding positioning components. However, for some smaller automotive parts, continuous and stable feeding and stamping of metal coils are required. Therefore, existing punch presses need to be improved to meet the needs of continuous and stable stamping of metal coils. Utility Model Content

[0028] Example
[0029] Please see Figures 1 to 7 As shown, this utility model provides a punch press for processing automotive parts, including a main unit 1 with a hydraulic rod 2, a stamping plate 3 fixedly mounted on the bottom of the hydraulic rod 2, a worktable 4 fixedly mounted on the main unit 1, the bottom of the stamping plate 3 for fixing the upper die of the stamping mold 5, the worktable 4 for fixing the lower die of the stamping mold 5, and a quantitative feeding component 6 provided on one side of the worktable 4.
[0030] The quantitative feeding assembly 6 includes a mounting frame 61, within which a drive mechanism drives a rotating active roller 62. Above the active roller 62 is a driven roller 63, with swing arms 64 rotatably connected to both ends of the driven roller 63. The swing arms 64 are hinged to the mounting frame 61 via pins 641. A horizontal support plate 8 is provided in front of the active roller 62, with two alternating limiting posts 66 fixed at the top of the support plate 8. An elastic reset member 67 is provided between the top of the front end of the swing arm 64 and the top of the mounting frame 61. A connecting shaft 68 is fixed between the rear ends of the two swing arms 64, with a pressure arm 681 fixed on the connecting shaft 68. A pressure rod 7 is provided above the pressure arm 681 and fixed on the stamping plate 3. The mounting frame 61 is fixed on the main unit 1.
[0031] In use, the metal coil is unwound by an external uncoiler. The metal coil slides between two limit posts 66 and is fed by the friction of the drive roller 62 and driven roller 63. During the stamping process, the pressure rod 7 and the stamping plate 3 rise and fall synchronously. When the stamping plate 3 descends, the pressure rod 7 acts on the pressure arm 681, which drives the swing arm 64 to rotate around the pin 641. At this time, the driven roller 63 disengages from the metal coil, stopping the feeding of the metal coil, and the stamping die 5 completes the stamping process. When the stamping plate 3 rises, the swing arm 64 rotates and resets around the pin 641 under the action of the elastic reset member 67. At this time, the driven roller 63 contacts the metal coil, and the metal coil is quantitatively fed according to the one-time rise and fall time of the stamping plate 3. The metal coil slides on the plane of the support plate 8 to ensure the stability of the metal coil feeding. The tops of the support plate 8 and the drive roller 62 are on the same horizontal plane, which will not be described in detail here.
[0032] The two ends of the driven roller 63 can be respectively embedded with eccentric holes 619.

[0034] The aforementioned pressure rod 7 is fixed to the side of the stamping plate 3 via the connecting rod 71. The pressure rod 7 is fastened to the end of the connecting rod 71, and the specific details will not be elaborated further.
[0035] As an embodiment of the present invention, the drive mechanism includes a driving gear 612 and a driven gear 613 that mesh with each other.

The driving gear 612 is driven to rotate by a servo motor 611, which is fixed to the mounting frame 61.
[0036] Correspondingly, protective covers 618 are fixed on both outer walls of the mounting bracket 61 to provide protection.
[0037] As an embodiment of this utility model, the elastic reset member 67 includes, from top to bottom, an adjusting bolt 671, an adjusting nut 672, a pressure plate 673, and a compression spring 674; the adjusting bolt 671 passes vertically through the mounting bracket 61 and is fitted with the adjusting nut 672 and the pressure plate 673, and the adjusting bolt 671 is threadedly connected to the mounting bracket 61; the adjusting nut 672 is threadedly connected to the adjusting bolt 671; the compression spring 674 is embedded in the swing arm 64 and abuts against the pressure plate 673.
[0038] During the rotation of the swing arm 64 around the pin 641, the compression spring 674 can be compressed or pushed to return the swing arm 64 to its original position. The position of the pressure plate 673 can be adjusted by adjusting the nut 672, thereby adjusting the initial position of the swing arm 64, which will not be described in detail here.
[0039] In one embodiment of this utility model, a guide roller 65 is provided in front of the support plate 8, and the two ends of the guide roller 65 are rotatably mounted on the mounting frame 61. The metal coil slides through the guide roller 65 between the two limiting posts 66, and when passing between the driving roller 62 and the driven roller 63, the tops of the guide roller 65, the support plate 8 and the driving roller 62 are on the same horizontal plane, which improves the straightness of the metal coil feeding and further ensures the stability of the feeding.
[0040] As an embodiment of this utility model, a push-pull quick clamp 616 is fixedly provided at the top of the mounting bracket 61, and a fork 617 is threadedly fastened to the output end of the push-pull quick clamp 616; a guide rod 684 is also fixedly provided on the connecting shaft 68; the fork 617 is used to push the guide rod 684 and cause the swing arm 64 to rotate, so that the driven roller 63 is lifted up, so as to facilitate the replacement and placement of the metal coil and improve the convenience of operation.

[0044] As an embodiment of this utility model, the rear end of the mounting frame 61 is provided with a material guiding assembly 69; the material guiding assembly 69 includes a lower clamping plate 691 and an upper clamping plate 692 with a sliding groove; the upper clamping plate 692 is fixed to the top of the lower clamping plate 691; the lower clamping plate 691 is fixed on the mounting frame 61 and located below the swing arm 64; the sliding groove matches the size of the coil and is used for horizontal guidance of the coil, further improving the straightness of the metal coil feeding and avoiding excessive gap between the mounting frame 61 and the stamping die 5, which would cause the metal coil to sag and bend.
[0045] In one embodiment of this utility model, the limiting post 66 is sleeved on the handle bolt, and the support plate 8 has an elongated hole that matches the handle bolt; the handle bolt passes through the elongated hole and is fastened to the connecting block; the plane of the connecting block abuts against the bottom end of the support plate 8.
