Description

Technical Field

[0001] This invention relates to the field of automotive parts processing technology, and in particular to a stamping and bending equipment for automotive connectors. Background Technology

[0002] Automotive parts include standard parts and non-standard parts. Most automotive connectors are non-standard parts. Currently, non-standard automotive metal parts are formed by cold stamping and bending. The raw material for connectors is generally steel sheet. The use of cold stamping to form automotive metal parts can bring better safety to vehicles.

[0003] In addition to bending, non-standard automotive connectors also require punching to allow bolts to be tightened at the punched holes during use. One type of non-standard automotive metal connector has a V-shaped structure, with the angle varying depending on the application. However, this presents significant challenges in the punching process after bending. The uncertainty of the punching angle necessitates the design of multiple punching dies, which also need to accommodate waste material removal. This makes the manufacturing process for this non-standard connector cumbersome and costly.

[0004] Therefore, a stamping and bending equipment for automotive connectors is proposed. By setting up a stamping and bending equipment that integrates three mechanisms—bending, punching, and punching waste discharge—the forming and processing of non-standard connectors can be made more efficient and convenient. Summary of the Invention

[0005] The purpose of this invention is to provide a stamping and bending equipment for automotive connectors, which solves the problem that existing automotive non-standard metal connector forming and processing devices need improvement.

[0016] Preferably, the bottom end of the stamping column is equipped with a slide block with a T-shaped cross-section, and the guide seat has a slide groove with a T-shaped cross-section. The two ends of the slide groove do not penetrate the guide seat.

[0035] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0036] Example 1

[0037] Reference Figure 1-9 A stamping and bending device for automotive connectors includes a base 1 and a top seat 12 connected by a support column, and a hydraulic cylinder 11 mounted on the top seat 12, and further includes:

[0038] The stamping and bending mechanism includes an upper die 6 and a lower die 4. The upper die 6 is installed at the bottom of the hydraulic cylinder 11, and the lower die 4 is installed on the base 1. When the stamping is in the working state, a V-shaped forming cavity 26 is formed between the upper die 6 and the lower die 4.

[0039] The punching mechanism includes two sets of drive columns 13, two sets of stamping columns 15, two sets of guide seats 14 and a punching drive component. The punching drive component controls the two sets of drive columns 13 to move vertically and limit their movement on the base 1. The two sets of guide seats 14 are respectively installed on the top of the two sets of drive columns 13. The bottom ends of the two sets of stamping columns 15 are respectively limited and tilted within the corresponding guide seats 14. The axis of the stamping column 15 is perpendicular to the forming slope of the lower die 4. The lower die 4 is provided with a punching hole 17 for the stamping column 15 to pass through.

[0040] The discharge mechanism includes an air pump 9, an air guide pipe 10, a conduction hole 22 formed on the forming inclined surface of the upper mold 6, a discharge hole 16 formed in the upper mold 6, a sliding cavity 24 formed in the upper mold 6, and a piston rod 25 that cooperates with the sliding cavity 24; the axis of the conduction hole 22 is collinear with the stamping hole 17, the conduction hole 22, the discharge hole 16 and the sliding cavity 24 are interconnected, and two sets of discharge holes 16, conduction holes 22 and sliding cavities 24 are respectively provided. The discharge hole 16 extends to the side end face of the upper mold 6, and the sliding cavity 24 extends to the other side end face of the upper mold 6. The air pump 9 is connected to the two sets of sliding cavities 24 through the air guide pipe 10 respectively.

[0041] It also includes an electronic control mechanism to drive the hydraulic cylinder 11, the air pump 9, and the punching drive to start or stop;

[0042] Furthermore, cutting plates 21 are installed on both sides of the upper mold 6. When the bending forming state is in progress, the inner end face of the cutting plate 21 slides with the outer end face of the lower mold 4. The two sides of the lower mold 4 are respectively connected to inclined downward discharge plates 5. Specifically, when the upper mold 6 is driven by the hydraulic cylinder 11 to press the lower mold 4, the sheet metal is bent and the excess sheet metal on both sides is retained outside the lower mold 4. The cutting plate 21 is used to cut off the excess sheet metal on both sides.

[0043] Furthermore, the forming surfaces of the upper mold 6 and the lower mold 4 are V-shaped structures respectively, and the axis lines of the two sets of punching holes 17 are perpendicular to the two inclined end faces of the V-shaped structure. Specifically, when the punching column 15 moves in the punching hole 17, it can ensure that the punching column 15 punches the metal plate vertically after forming.

[0044] Furthermore, positioning cylinders 7 are installed on both sides of the lower mold 4, and positioning pins 8 are installed on both sides of the upper mold 6. When the positioning pins 8 are bent, they are engaged with the positioning cylinders 7. Specifically, during the stamping process of the upper mold 6 and the lower mold 4, the positioning pins 8 are engaged with the positioning cylinders 7.

[0045] In this embodiment: by placing the metal plate on top of the lower mold 4, the hydraulic cylinder 11 controls the upper mold 6 to move downwards to stamp and bend the metal plate. The cutting plate 21 removes excess material from both sides of the metal plate to complete the first step of stamping and bending the metal plate. The extension end of the stamping column 15 is initially located inside the lower mold 4. By controlling the two sets of drive columns 13 to move upwards, the guide seat 14 and the stamping column 15 slide together to push the corresponding stamping column 15 along the stamping hole 17 to punch the metal plate. When the stamping column 15 is in the terminated state, the stamping column... The extended end of 15 is located inside the conduction hole 22 to complete the punching task after bending the non-standard metal plate in the second step. When the punching is finished in the second step, the punching waste is pushed through the conduction hole 22 by the punching column 15 to the discharge hole 16. The air pump 9 inflates the waste to drive the piston rod 25 to slide in the sliding cavity 24. The piston rod 25 pushes the punching waste out of the discharge hole 16. The air pump 9 controls the piston rod 25 to reset, thus completing the punching waste removal task in the third step. This realizes a method for efficient and accurate bending and punching of non-standard metal connectors for automobiles.

[0046] In this embodiment, by opening a punching hole 17 on the bending and forming end face of the lower die 4 and a conduction hole 22 on the bending and forming end face of the upper die 6, the punching mechanism avoids the concentrated stress area of ​​the punching and bending mechanism. By pre-setting the punching hole 17 and conduction hole 22 perpendicular to the bending and forming end face, the stability of the metal punching path and the accuracy of metal punching can be guaranteed. By setting an output mechanism, the discharge hole 16 and sliding cavity 24 opened in the upper die 6 are used to collect and output the punching waste. The output direction of the punching waste is opposite to the output direction of the non-standard bent plate. The output direction of the punching waste is located above the metal inlet side, realizing the separate output of the punching waste and the bent metal connector. This facilitates the separate collection of the punching waste and the metal connector, avoiding the complicated operation of screening punching waste and metal connector. This realizes a punching and bending equipment that can accurately bend and punch non-standard metal plates and facilitates the separate recycling of waste and bent forming material.
