Description

Technical Field

[0001] This application relates to the technical field of sheet metal punching, and in particular to a punching device for sheet metal processing. Background Technology

[0002] In the field of sheet metal processing, punching is a common and critical process that directly affects the product quality and production efficiency of sheet metal parts. Currently, conventional sheet metal punching equipment has several drawbacks in practical applications:

[0003] I. Insufficient punching accuracy and stability: Traditional devices often rely on simple upper and lower die cooperation, lacking structural design for precise positioning and stable clamping of sheet metal parts. Sheet metal parts are prone to displacement and warping during punching due to pressure, leading to punching position deviations and irregular hole shapes, affecting subsequent assembly and use. This is especially true for sheet metal parts with high precision requirements, making it difficult to meet quality standards. II. Inconvenient waste removal: Waste generated during punching easily remains in the lower die or working area. If not cleaned in time, it will affect subsequent punching operations, such as hindering the next die's punching or scratching the surface of the sheet metal part. Existing devices mostly rely on manual waste removal, which is inefficient and increases the labor intensity of operators, making it unsuitable for large-scale, continuous production needs. Therefore, to solve the above problems, this application provides a punching device for sheet metal processing. Utility Model Content

[0004] To address the aforementioned problems, this application provides a punching device for sheet metal processing.

[0005] This application provides a punching device for sheet metal processing, including a conveyor table, a bracket set above the conveyor table, a hydraulic cylinder 1 installed on the bracket, a receiving groove opened on the conveyor table, a hydraulic cylinder 2 set corresponding to the receiving groove, a support sleeve adapted to and connected to the hydraulic cylinder 2 and located at the receiving groove, a pusher structure for cleaning waste material, an upper pressure block connected to the hydraulic cylinder 1, and a punching block adapted to the upper pressure block and used for punching.

[0006] The sheet metal is punched and cut by the relative movement of hydraulic cylinder one and hydraulic cylinder two, using the cooperation of the stamping block and the support sleeve. After stamping, the waste is cleaned up by the pusher structure.

[0007] By setting a support sleeve structure at the receiving groove position of the conveyor table as the lower receiving, and setting an upper pressure block and a stamping block on the bracket above the conveyor table to cooperate with the support sleeve, the stamping block and the inner wall of the support sleeve are fitted with a clearance, so that the sheet metal can be punched and cut when the hydraulic cylinder one and hydraulic cylinder two move in opposite directions.

[0008] Preferably, the second hydraulic cylinder is fitted and installed below the conveyor table via a mounting bracket to provide power and positional support for the support sleeve, allowing the support sleeve to cooperate with the stamping operation at the receiving groove.

[0009] Preferably, the pushing structure includes a fixed frame and a pushing block. The fixed frame is assembled with a support sleeve or a conveyor table, and the pushing block is movably disposed inside the support sleeve to clean up the waste material after stamping.

[0010] Preferably, the stamping block is fixedly connected to the upper pressure block, and the stamping block is fitted with the inner wall of the support sleeve with a clearance to ensure stable punching and cutting operations, while facilitating the falling of waste materials and subsequent cleaning.

[0011] Preferably, the mounting bracket is a connection structure adapted to the hydraulic cylinder two and the conveyor table, and can be securely installed by means of bolts, buckles, etc., to ensure that the hydraulic cylinder two drives the support sleeve to operate accurately at the receiving groove, thereby improving the operational stability of the device.

[0012] Preferably, the pusher block's travel within the support sleeve is adapted to the stamping operation of the support sleeve. During stamping, the pusher block can be concealed within the support sleeve without affecting the punching. After stamping, it can effectively act on the waste material, enabling convenient waste removal. Furthermore, the pusher block slides with the inner side of the support sleeve to ensure smooth pushing action.

[0013] Preferably, the upper pressure block is rigidly connected to the output end of the hydraulic cylinder and can move stably with the hydraulic cylinder to provide stable pressure for the stamping block, ensuring the accuracy and effect of punching and cutting. The connection surfaces of the upper pressure block and the stamping block are machined to ensure that the two are firmly assembled and the force is uniform.

[0014] In summary, this application includes the following beneficial technical effects:

[0015] By setting a support sleeve structure at the receiving groove position of the conveyor table as the lower receiving, and setting an upper pressing block and a stamping block on the bracket above the conveyor table to cooperate with the support sleeve, the stamping block and the inner wall of the support sleeve are fitted with a clearance, so that when hydraulic cylinder one and hydraulic cylinder two move in opposite directions, the sheet metal can be punched and cut; after the stamping is completed, hydraulic cylinder two moves downward, at which time the pusher block of the pusher structure hidden inside the support sleeve directly acts on the waste material inside, completing the convenient cleaning of the waste material.

[0021] The following is in conjunction with the appendix Figure 1 - Figure 4 This application will be described in further detail.

[0022] Example 1:

[0023] This sheet metal punching device is used to solve the problems of punching sheet metal parts and cleaning up waste. Through the coordinated operation of various components, it efficiently completes the sheet metal processing flow. The following is a detailed description of its specific implementation method in conjunction with the structure:

[0024] I. Overall Assembly and Basic Principles

[0025] The sheet metal punching device mainly consists of a conveyor table 1, a bracket 2 mounted above the conveyor table 1, a hydraulic cylinder 3 mounted on the bracket 2, a receiving groove 4 on the conveyor table 1, a hydraulic cylinder 5 corresponding to the receiving groove 4, a support sleeve 6 adapted to and connected to the hydraulic cylinder 5 and located at the receiving groove 4, a pusher structure 7 for cleaning waste material, an upper pressure block 8 connected to the hydraulic cylinder 3, and a punching block 9 adapted to the upper pressure block 8 and used for punching. In use, the sheet metal part is conveyed to the designated position via the conveyor table 1. The relative movement of the hydraulic cylinders 3 and 5 allows the punching block 9 to engage with the support sleeve 6, performing punching and cutting on the sheet metal part. After punching, the pusher structure 7 cleans up the waste material, ensuring continuous and stable operation of the device.

[0026] II. Detailed Implementation Instructions for Each Component

[0027] (a) Conveyor platform and support

[0028] The conveyor table is the basic platform for conveying and supporting sheet metal parts, providing a stable working surface for subsequent punching operations. Its receiving groove 4 is compatible with the support sleeve 6, stamping block 9, etc., to ensure accurate punching position. The bracket 2 is installed above the conveyor table 1 to fix the hydraulic cylinder 3 and provide installation support for the hydraulic cylinder 3, so that the output end of the hydraulic cylinder 3 can act vertically on the sheet metal part, ensuring the stability of the punching pressure direction.

[0029] (ii) Hydraulic cylinder one and hydraulic cylinder two

[0030] Hydraulic cylinder 3 is mounted on bracket 2, and its output end is connected to pressure block 8 and punching block 9. During operation, it provides downward punching power to drive punching block 9 to complete the punching action. Hydraulic cylinder 5 is adapted to be installed under conveyor table 1 through mounting bracket 51, providing power and position support for support sleeve 6. During operation, it can drive support sleeve 6 to move up and down at receiving groove 4. In cooperation with hydraulic cylinder 3, it realizes the clamping and punching operation of sheet metal parts. For example, before punching, hydraulic cylinder 5 drives support sleeve 6 to rise, and cooperates with pressure block 8 to initially position sheet metal parts; during punching, it works with hydraulic cylinder 3 to ensure the stability of punching.

[0031] (iii) Support sleeve and stamping block

[0032] The support sleeve 6 is positioned corresponding to the receiving groove 4, and its inner wall is fitted with the stamping block 9 with a clearance, providing lower support for the punching operation and ensuring clean cutting edges of the sheet metal parts during punching. Simultaneously, the support sleeve 6 provides installation and operating space for the pusher structure 7. After punching, the pusher structure 7 can move inside the support sleeve 6 to clean up waste material. The stamping block 9 is fixedly connected to the upper pressure block 8 and moves with the hydraulic cylinder 3. Utilizing its own shape and cutting edge, it cooperates with the support sleeve 6 to complete the punching and cutting of the sheet metal parts. Due to the clearance fit with the support sleeve 6, the punching waste material can fall smoothly, facilitating subsequent cleaning.

[0033] (iv) Material pushing structure

[0034] The pushing structure 7 includes a fixed frame 71 and a pushing block 72. The fixed frame 71 is assembled with the support sleeve 6 or the conveyor table 1 to provide an installation base and movement limit for the pushing block 72. The pushing block 72 is movably set inside the support sleeve 6. During the stamping operation, it is hidden inside the support sleeve 6 and does not affect the punching. After the stamping is completed, it can be directly pushed out of the support sleeve 6 by the power (such as manual operation, the action of the associated hydraulic cylinder, etc., which can be adapted according to the actual design) to push the waste material out of the support sleeve 6, so as to realize convenient waste material cleaning and ensure that the next punching operation is not affected by waste material residue.

[0035] (v) Upper pressure block

[0036] The upper pressure block 8 connects the hydraulic cylinder 3 and the stamping block 9, transmitting the power of the hydraulic cylinder 3. At the same time, in the initial stage of the punching operation, it can work with the support sleeve 6 to initially clamp the sheet metal parts, preventing the sheet metal parts from shifting during punching, ensuring the accuracy of the punching position, and making the punching block 9 punch more stably and accurately.

[0037] III. Implementation of the Complete Work Process

[0038] The operation begins with the sheet metal part being conveyed to a designated position on conveyor table 1 via a conveyor device (not shown in the diagram, but compatible with conventional conveyor mechanisms), corresponding to the positions of support sleeve 6 and stamping block 9. Subsequently, hydraulic cylinder 2 5 actuates, causing support sleeve 6 to rise, which, in conjunction with upper pressure block 8, initially clamps the sheet metal part. Then, hydraulic cylinder 1 3 actuates, driving upper pressure block 8 and stamping block 9 downwards. The stamping block 9, in conjunction with support sleeve 6, punches and cuts holes in the sheet metal part, and the punching waste falls into the inner area of ​​support sleeve 6. After punching is completed, hydraulic cylinder 2 5 drives the support sleeve 6 to move downwards to reset (or the stroke can be adjusted as needed). At this time, the pushing structure 7 is triggered, and the pushing block 72 moves inside the support sleeve 6, pushing the waste material out of the support sleeve 6 and dropping it below the receiving groove 4 or the designated waste collection area (which can be adapted to a waste collection box, etc., not shown in the figure). Afterwards, hydraulic cylinder 1 3 drives the upper pressure block 8 and the punching block 9 to reset, and the conveyor table 1 continues to convey the next sheet metal part, entering the next round of punching operation cycle. This achieves continuous and stable punching processing of sheet metal parts. With the cooperation of various components, the effect of efficient punching and convenient waste removal is achieved.
