Abstract
Description
Technical Field
[0001] This utility model relates to the field of stamping die technology, specifically a stamping die with a dual-station positioning mechanism. Background Technology
[0002] Stamping dies are special process equipment used in cold stamping to process materials (metal or non-metal) into parts (or semi-finished products). They are called cold stamping dies (commonly known as cold stamping dies). Stamping is a pressure processing method that uses dies mounted on a press to apply pressure to materials at room temperature, causing them to separate or plastically deform, thereby obtaining the desired parts.
[0003] When existing stamping dies punch holes in rectangular pipes, the rectangular pipes lack a positioning device for positioning, and the rectangular pipes are also prone to displacement during processing, resulting in inaccurate hole positions and affecting product quality.
[0004] Therefore, a solution is needed. Utility Model Content
[0005] (a) Technical problems to be solved
[0006] To address the shortcomings of existing technologies, this utility model provides a stamping die with a dual-station positioning mechanism to solve the problems mentioned in the background section.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a stamping die with a dual-station positioning mechanism, comprising a device body, the device body including a worktable, a lower stamping die device, an upper stamping die device, a pipe limiting device, and a second limiting block. The lower stamping die device and the second limiting block are both fixed to the top of the worktable by screws. A set of pipe limiting devices is provided, and this set is fixed to the right end of the lower stamping die device by bolts. A set of second limiting blocks is provided, and this set of second limiting blocks is located to the right of the set of pipe limiting devices.

The pipe limiting device includes a pipe sleeve block, an embedded mounting block, and a sliding mounting block. The pipe sleeve block and the embedded mounting block are smoothly transitioned and integrally formed. The pipe sleeve block and the embedded mounting block are rectangular in shape. The embedded mounting block is located at the left end of the pipe sleeve block. There are two sets of sliding mounting blocks, which are located at the top and bottom of the embedded mounting block, respectively. A set of through holes is opened at the top of the pipe sleeve block, and several sets of locking holes are opened on the surface of the embedded mounting block.
[0009] Preferably, the stamping die device includes a main body die block and a side mounting block. The side mounting block is provided in a set, and the set of side mounting blocks is located on the front and rear sides of the main body die block respectively. The surface of the side mounting block is also provided with a number of locking holes.
[0010] Preferably, the lower mold block of the main body has a rectangular structure, and a set of main insertion slots are provided on the right side of the lower mold block of the main body.

[0013] (III) Beneficial Effects
[0014] This utility model provides a stamping die with a dual-station positioning mechanism. It has the following beneficial effects:
[0015] In this solution, a stamping die with a dual-station positioning mechanism is configured with a pipe limiting device and a second limiting block to form a dual-station positioning system. The pipe fitting block of the pipe limiting device can fit onto a rectangular pipe. The embedded mounting block, in conjunction with the sliding mounting block, slides with the main insertion slot and small slider slot of the lower stamping die device to achieve initial positioning and installation stability of the rectangular pipe.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figure 1-4 This utility model provides a technical solution:
[0023] Example 1
[0024] The problem to be solved is that existing stamping dies do not have a positioning device to position the rectangular pipe when stamping holes, and the rectangular pipe is also prone to displacement during processing, resulting in inaccurate hole positions and affecting product quality.
[0025] The solution is as follows: A stamping die with a dual-station positioning mechanism includes a device body 1. The device body 1 includes a worktable 2, a lower stamping die device 3, an upper stamping die device 4, a pipe limiting device 5, and a second limiting block 6. The lower stamping die device 3 and the second limiting block 6 are both fixed to the top of the worktable 2 by screws. A set of pipe limiting devices 5 is provided, and a set of pipe limiting devices 5 is fixed to the right end of the lower stamping die device 3 by bolts. A set of second limiting blocks 6 is provided, and a set of second limiting blocks 6 is located to the right of a set of pipe limiting devices 5. The upper stamping die device 4 is displaced... The stamping die device 3 is located above the pipe limiting device 5. The pipe limiting device 5 includes a pipe sleeve block 7, an embedded mounting block 8, and a sliding mounting block 9.

The upper stamping die device 4 descends. The stamping opening column 21 passes through the through hole 10 of the pipe sleeve block 7 to open the pipe. The dual-station positioning of the front pipe limiting device and the rear second limiting block greatly improves the stability of the pipe and reduces the risk of displacement. The pipe sleeve block 7 fits the rectangular pipe and provides initial positioning. The embedded installation block 8 slides with the main insertion groove 14 of the lower stamping die device 3 through the sliding installation block 9 to achieve rapid installation and positioning. Slide the embedded mounting block 8 into the main insertion slot 14, slide the sliding mounting block 9 along the small slider slot 15 to the appropriate position, and fix it by passing the bolt through the locking hole 13.

[0039] Specifically, a comparison of relevant test data and practical application data for this solution.
[0040]
[0041] Data Description
[0042] Opening position deviation: refers to the straight-line distance between the actual center of the opening after stamping of a rectangular pipe and the theoretical design center, expressed in millimeters (mm). The smaller the value, the higher the positioning accuracy. This indicator directly reflects the positional accuracy of the stamped opening.
[0043] Product yield: refers to the proportion of products with an opening position deviation of ≤0.15mm (the industry-standard acceptable level) in a single batch of processing. This indicator reflects the stability of product quality.
[0044] Number of displacements per batch: This refers to the number of times the pipes experience significant displacement (deviation > 0.2 mm) due to positioning failure during the processing of 50 rectangular pipes. This indicator reflects the stability of the positioning mechanism's constraint on the pipes.
[0045] Data Validity Statement
[0046] Consistency of experimental conditions: The data were obtained from the same experimental environment, all for rectangular metal pipes (material Q235 steel) with specifications of 100mm×50mm×2mm, using the same stamping parameters (stamping pressure 50kN, stamping speed 10mm / s), and were completed by the same operator and the same stamping equipment, thus eliminating the interference of differences in equipment, personnel, and materials on the results.
[0047] Sample size rationality: Each indicator is based on experimental data statistics from 10 batches (50 pieces per batch). The sample size meets the verification requirements for small-batch production. The data fluctuation range (± value) is calculated through standard deviation and conforms to the normal range of process fluctuations in actual production.
[0048] Correlation of indicators: The reduction in opening position deviation is directly related to the improvement of product yield, while the reduction in the number of shifts is the core reason for the reduction in deviation. The three form a logical closed loop, which can effectively prove the technical effect of the dual-station positioning mechanism (pipeline limiting device + second limiting block) on improving positioning accuracy, reducing shifts, and stabilizing product quality.

This utility model, through the combination of the above-mentioned components, can accurately position the rectangular pipes, ensuring precise punching hole positions.
