Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically a punching mold with an auxiliary punching mechanism. Background Technology

[0002] In the field of machining, it is often necessary to machine holes on the side wall of round tubes. Traditional machining methods mostly use drilling or milling, which are too inefficient and cannot meet the needs of modern production.

[0003] Among the existing technologies, the punching die with an auxiliary punching mechanism proposed in the patent announcement number CN205270536U includes an upper die base and a lower die base, which are connected by guide posts. An upper punch is connected to the bottom of the upper die base, and a round tube placement part is longitudinally arranged on the lower die base. An auxiliary punch is provided on the outside of the upper punch.

[0004] Existing technology devices cannot change the punching position according to requirements. When the punching position needs to be changed, the mold needs to be replaced. At the same time, the raw material may rotate during processing, causing the punching position to shift due to the rotation of the raw material during punching. To address this, we propose a punching mold with an auxiliary punching mechanism. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a punching die with an auxiliary punching mechanism. The precise alignment of the lower die and the punching position can be steplessly adjusted, which can prevent the raw material from rotating during processing and prevent the punching position from shifting due to the rotation of the raw material during punching. This can effectively solve the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a punching die with an auxiliary punching mechanism, comprising a base plate, a hydraulic press support frame, a die assembly, a fixing and adjusting assembly, and a hydraulic press;

[0007] Base plate: A hydraulic press support frame is fixedly connected to the upper rear side, and a hydraulic press is fixedly connected to the upper end of the hydraulic press support frame. A mold assembly and a fixing and adjusting assembly are installed on the upper end of the base plate.

[0008] Mold assembly: includes support columns, lower mold, sliding rod, upper mold, adjusting threaded rod, limiting telescopic rod, upper sliding block, punching rod, mounting plate, dovetail groove, dovetail slider, lower sliding block and damping rod. The upper corners of the base plate are fixedly connected to four support columns. The upper corners of the lower mold are respectively fixedly connected to the outer upper ends of the four support columns. The lower sliding block is slidably connected to the lower inner side of the lower mold. The upper end of the support column is fixedly connected to the sliding rod. The four corners of the upper mold are respectively slidably connected to the sliding rod. The upper inner side of the upper mold is slidably connected to the upper sliding block. The lower sliding block has a circular through hole in the middle. The base plate supports the hydraulic press via a hydraulic press support frame. The support columns and sliding rods form a four-column guide frame. The positions of the upper sliding block, punching rod, and lower sliding block are adjusted by adjusting the threaded rod. The punching rod is limited by the dovetail groove and dovetail slider. The hydraulic device drives the mounting plate to move, and at the same time drives the punching rod to punch the raw material fixed between the lower and upper molds. Adjusting the position of the threaded rod punching the hole and simultaneously controlling the relative position of the upper and lower sliding blocks forms an adjustable punching system, which allows punching to be performed on the raw material as needed.

[0009] Furthermore, the mold assembly also includes an adjusting threaded rod and a limiting telescopic rod. The adjusting threaded rod is rotatably connected to the outer upper end of the upper mold. The upper and lower ends of the limiting telescopic rod are respectively fixedly connected to the upper sliding block and the lower sliding block. The upper end of the limiting telescopic rod is threadedly connected to the adjusting threaded rod. By adjusting the position of the punching hole on the adjusting threaded rod, the relative positions of the upper and lower sliding blocks are controlled synchronously, forming an adjustable punching hole, which allows punching to be performed on the raw material as needed.

[0010] Furthermore, the mold assembly also includes a punching rod, a mounting plate, a dovetail groove, and a dovetail slider. The mounting plate is fixedly connected to the lower end of the hydraulic press. The four corners of the dovetail groove are slidably connected to the sliding rod. A dovetail groove is formed in the middle of the lower end of the mounting plate. A dovetail slider is slidably connected to the inner side of the dovetail groove. The lower end of the dovetail slider is fixedly connected to the punching rod, and the outer side of the punching rod is slidably connected to the upper sliding block. The dovetail slider moves along the dovetail groove, driving the punching rod to be precisely positioned. The mounting plate is connected to the power output end of the hydraulic press, driving the device to perform the punching operation.

[0011] Furthermore, the mold assembly also includes a damping rod, which is fixedly connected to the middle of the rear end of the mounting plate, and the lower end of the damping rod is fixedly connected to the outer side of the upper mold. The damping rod connects the mounting plate and the upper mold, forming a shock-absorbing and stabilizing device to absorb the impact vibration of the hydraulic press.

[0012] Furthermore, the fixed adjustment assembly includes a T-shaped slide, a moving rod, and a circular electromagnetic push plate. Two T-shaped slides are correspondingly formed on the left and right sides of the upper center of the base plate. A moving rod is slidably connected to the inner side of each T-shaped slide, and a circular electromagnetic push plate is fixedly connected to the upper end of the moving rod. The circular electromagnetic push plate is slidably connected to the inner side of the lower mold. The circular electromagnetic push plate slides and pushes the workpiece within the T-shaped slide via the moving rod, offering advantages such as automatic centering and rapid clamping. Simultaneously, the electromagnetic device prevents the raw material from rotating during processing, thus preventing displacement of the punching position due to material rotation during punching.

[0013] Furthermore, the fixed adjustment assembly also includes a motor mounting base, a dual-axis motor, and threaded rods. The motor mounting base is fixedly connected to the upper center of the base plate, and the dual-axis motor is fixedly connected to the inner side of the motor mounting base. The output shaft of the dual-axis motor is fixedly connected to a threaded rod, the threads of the two threaded rods are opposite, and the threaded rods are threadedly connected to the moving rod. The dual-axis motor drives the opposing threaded rods to move the moving rod synchronously in opposite directions, and the motor mounting base provides stable support, forming a bidirectional automatic clamping system with balanced clamping force and high efficiency.

[0015] 1. This punching die with an auxiliary punching mechanism adjusts the positions of the upper sliding block, punching rod, and lower sliding block by adjusting the threaded rod. The punching rod is limited by the dovetail groove and dovetail slider. The mounting plate is moved by the hydraulic device, which simultaneously drives the punching rod to punch the raw material fixed between the lower and upper dies. Adjusting the punching position of the threaded rod synchronously controls the relative position of the upper and lower sliding blocks. The punching position can be steplessly adjusted to adapt to the processing requirements of different workpieces.

[0016] 2. This punching die with an auxiliary punching mechanism has a circular electromagnetic push plate that slides and pushes the workpiece in the T-shaped groove through a moving rod. It has the advantages of automatic centering and quick clamping. At the same time, the electromagnetic device can prevent the raw material from rotating during processing, and prevent the punching position from shifting due to the rotation of the raw material during punching.
