Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, and more specifically, to a stamping die with a protective device. Background Technology

[0002] Stamping dies are known to be the core tools for forming and processing metal sheets. At room temperature, external force is applied to the sheet metal through a press and a die, causing it to undergo plastic deformation or separation, thereby obtaining parts of the required shape and size. In traditional stamping dies, operators need to frequently manually place or remove workpieces during the opening and closing process. If the action is delayed or the equipment malfunctions, the operator's hand may be crushed by the die, causing serious work-related injuries. In addition, material breakage or flying debris during stamping may also cause injury to the operator. Therefore, existing stamping dies are all equipped with corresponding protective measures.

[0003] However, in actual use, most existing protective measures are complex in structure, and some require additional power for control. Therefore, this utility model proposes a stamping die with a protective device as a further improvement. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a stamping die with a protective device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stamping die with a protective device, comprising an upper die and a lower die, wherein the bottom of the upper die is inserted into the top of the lower die.

[0006] It also includes: fixed frame, movable linkage, support base and protective enclosure;

[0007] The upper mold has an upper mold base at its top, and the lower mold has a lower mold base at its bottom; the fixing frame for limiting movement is slidably connected to the upper mold base, and the support base is fixedly installed on the front of the fixing frame.

[0008] One end of the movable connecting rod is rotatably connected to a fixed long rod fixedly installed at the bottom of the upper mold base, and the protective enclosure used to cover the upper mold and the lower mold is fixedly installed at the other end of the movable connecting rod;

[0009] The movable connecting rod is rotatably connected to the support base;

[0010] A limit mechanism is provided between the upper mold base and the lower mold base.

[0011] Furthermore, the movable link includes: a connecting rod and a swinging link;

[0012] One end of the fixed long rod is rotatably connected to one end of the connecting rod, the other end of the connecting rod is rotatably connected to one end of the swinging connecting rod, and the other end of the swinging connecting rod is fixedly connected to the protective enclosure.

[0013] Furthermore, the shape of the swing link is set to L-shape;

[0014] The swing link includes a power arm link and a resistance arm link. The fixed connection between the power arm link and the resistance arm link is set as a fulcrum. The fulcrum of the swing link is rotatably connected to the support base.

[0015] The end of the power arm connecting rod away from the fulcrum is rotatably connected to the connecting rod, and the end of the resistance arm connecting rod away from the fulcrum is fixedly connected to the protective enclosure.

[0016] Furthermore, a sensor for sensing objects is fixedly installed at the bottom of the upper mold base.

[0017] Furthermore, the protective enclosure has multiple parallel-arranged through slots.

[0018] Furthermore, the limiting mechanism includes: a guide post and a guide sleeve;

[0019] The guide post is fixedly installed at the bottom of the upper mold base, and the guide sleeve is fixedly installed at the top of the lower mold base. The bottom of the guide post is inserted into the top of the guide sleeve.

[0020] Furthermore, the support base is T-shaped, and its bottom is rotatably connected to the fulcrum of the swing link.

[0021] The technical effects and advantages of this utility model are as follows:

[0022] Compared with existing technologies, by setting up a movable connecting rod, when the stamping die equipment drives the upper die to press against the lower die for stamping operations, the movable connecting rod, which is fixed on the support base, makes a mechanical swinging motion. The movable connecting rod drives the protective plate to provide front protection, preventing workers' fingers from being squeezed during operation, and preventing the die or material from being broken and splashed out during stamping, thus avoiding certain safety hazards. Since the movable connecting rod has a simple structure and uses the movement of the upper die to drive the movable connecting rod for protection, no additional power is required for control, making it highly practical.
