Description

Technical Field

[0001] This utility model relates to the field of sheet metal stamping equipment technology, specifically a continuous stamping device for thin sheet metal. Background Technology

[0002] Sheet metal parts are widely used in home appliances, automobiles, and machinery manufacturing due to their lightweight, high strength, and ease of forming. Stamping is a common and highly efficient and adaptable process for forming sheet metal, especially in continuous stamping scenarios. By sequentially completing multiple processes, it can effectively improve processing efficiency and reduce manufacturing costs.

[0003] Existing sheet metal stamping equipment typically employs a fixed die structure and linear feeding method. A typical structure involves fixing the stamping die on the punch table, with a feeding mechanism gradually advancing the metal strip along a straight line. Each time the strip reaches a set position, the punch is driven to complete a stamping action. Continuous feeding and stamping are achieved through a fixed module and linear guide rail.

[0004] However, the above-mentioned traditional stamping methods have the following shortcomings when processing small-sized or thin parts that require high-frequency stamping:

[0005] Poor position adaptability: Traditional mold layout is fixed and the impact angle of the punch cannot be adjusted, making it difficult to cope with sheet metal structures of different shapes or positions, which reduces the versatility of the process and the processing accuracy.

[0006] The stamping path is singular: the linear feeding mode limits the freedom of process layout and makes it difficult to achieve high-density arrangement of circular or non-linear paths.

[0007] Limited stamping efficiency: Since each stamping requires waiting for the feeding to complete, the processing cycle is limited, making it impossible to achieve truly high-frequency continuous stamping.

[0008] Therefore, how to construct a structure with adjustable impact direction, support for continuous feeding along a circumferential path, and the ability to arrange multiple punches to achieve multi-station linkage stamping has become a key issue that needs to be addressed in the current continuous stamping technology for thin sheet metal.

[0016] In a preferred embodiment, the present invention can be further configured such that: one end of the plunger rod is provided with a spring that abuts against the inside of the plunger cylinder for resetting the movement of the plunger rod.

[0018] In a preferred embodiment, the present invention can be further configured such that a piston ring is sleeved on the surface of the plunger rod and slides against the inner wall of the plunger cylinder.

[0038] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0039] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of this invention.

[0040] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a continuous stamping device for thin sheet metal.

[0041] Combination Figures 1-5 As shown, the present invention provides a continuous stamping device for thin sheet metal, comprising: a punch table 100, a guide seat 200, a stamping assembly 300, and an adjusting rod 400.

[0042] The top surface of the punching platform 100 is fixedly mounted with a support frame 110, and the top surface of the support frame 110 is fixedly mounted with a drive motor 111. A guide seat 200 is rotatably mounted on the inner side of the support frame 110, and a slip ring 210 is slidably sleeved on the surface of the guide seat 200. The two ends of the slip ring 210 are rotatably connected to the inner side of the support frame 110 through a shaft pin, which enables the guide seat 200 to rotate relative to the support frame 110.

[0043] The adjusting rod 400 is fixed to the top surface of the support frame 110, and the output end of the adjusting rod 400 is connected to the connecting rod 410, which is connected to the surface of the slip ring 210. By driving the adjusting rod 400, the slip ring 210 is tilted, thereby realizing the adjustment of the deflection angle of the guide seat 200 within the slip ring 210.

[0044] The bottom surface of the guide seat 200 is provided with a turntable seat 220, and the bottom surface of the turntable seat 220 is provided with a ball socket seat 221. The stamping assembly 300 is rotatably mounted on the surface of the punch table 100. The stamping assembly 300 includes a cylinder liner seat 310, a stamping seat 320, a plurality of plunger rods 330 and a punch 340.

[0045] The cylinder liner seat 310 has several plunger cylinders 311 on its inner side, and several plunger rods 330 are slidably sleeved on the inner side of the plunger cylinders 311. Each plunger rod 330 has a ball head 331 at its top end. The ball head 331 matches the ball socket seat 221 on the bottom surface of the turntable seat 220, realizing a universal connection structure between the ball head 331 and the ball socket seat 221.

[0046] The inner side of the cylinder liner seat 310 is also provided with several hydraulic flow channels 312. Each hydraulic flow channel 312 is connected to the corresponding plunger cylinder 311. The hydraulic flow channel 312 is filled with hydraulic oil, which can realize the hydraulic drive of the plunger rod 330 during equipment operation.

[0047] The stamping seat 320 is fixedly connected to the bottom surface of the cylinder liner seat 310. The interior of the stamping seat 320 is provided with a plunger cavity for guiding the sliding of the punch 340. The punch 340 is slidably sleeved on the inner side of the plunger cavity. The punch 340 consists of a punch rod and a punch body, which are connected by threads for easy replacement of the punch 340.

[0048] To enhance the reset function, one end of the plunger rod 330 is provided with a spring that abuts against the inside of the plunger cylinder 311 to achieve automatic reset of the plunger rod 330; in addition, a piston ring is also sleeved on the surface of the plunger rod 330 and slides against the inner wall of the plunger cylinder 311 for sealing and guiding.

[0049] Working principle and usage process of this utility model:

[0050] Before the equipment is put into operation, the thin sheet metal material to be processed is first placed on the punch table 100 and pushed along the path of the ring slide rail 120, with each material pushing against the other. After the drive motor 111 is started, it drives the guide seat 200 to rotate inside the slip ring 210. The guide seat 200 is dynamically connected to the ball head-ball socket structure between the turntable seat 220 at its bottom and multiple plunger rods 330. At the same time, driven by the adjusting rod 400, the guide seat 200 is deflected at an angle by tilting the slip ring 210, so that the guide seat 200 can be flexibly adapted to different stamping pitches or angles.

[0051] Subsequently, the cylinder liner seat 310 and the stamping seat 320 begin to rotate synchronously under the drive of the motor. Several plunger cylinders 311 are distributed inside the cylinder liner seat 310. The plunger rod 330 slides in it and is pushed by the hydraulic oil in the hydraulic flow channel 312. After rotating to its original position, it is pulled back by the sliding connection between the turntable seat 220 and the bottom surface of the slip ring 210, thereby causing the punch 340 to reciprocate.

[0052] As the sheet metal material slides along the ring slide rail 120, it aligns sequentially with multiple punches 340. After completing one stamping operation in the plunger cavity, the punches 340 automatically reset. Because the stamping components are circumferentially distributed, the material can achieve multiple continuous stamping actions in one sliding path, thereby completing the integrated processing of multiple processes.

[0053] In the description of this specification, the terms "one embodiment," "some embodiments," "specific embodiment," etc., refer to a specific feature, structure, material, or characteristic described in connection with that embodiment or example, which is included in at least one embodiment or example of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0054] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
