Description

Technical Field

[0001] This utility model relates to the field of punch press technology, specifically a pneumatic protection device for punch presses. Background Technology

Unless otherwise specified, the embodiments and features described in this application can be combined with each other. All other embodiments obtained by those skilled in the art based on the embodiments of the utility model without creative effort are within the scope of protection of the utility model.

[0045] It should be noted that if the utility model embodiment involves directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0046] Furthermore, "multiple" refers to two or more. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of a person skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by the utility model.

[0047] Please see Figure 1-5 A pneumatic protection device for a punch press includes a base 1, a punching seat 2, a punching table 5, a top platform 6, and a punching cylinder assembly 8, arranged sequentially from top to bottom. The punching cylinder assembly 8 is mounted at the center of the top platform 6, with its output end connected to the top center of the punching table 5, and is used to drive the punching table 5 to move up and down for punching operations. A punching seat recovery through hole 11 for mounting the punching seat 2 is provided at the center of the top surface of the base 1. The base 1 also has a bottom mounting cavity 12 connected to the punching seat recovery through hole 11, providing installation space for a punching seat recovery mechanism 3. The punching seat recovery mechanism 3 is used to support the punching seat 2 during the punching process and can retract the punching seat 2 into the punching seat recovery through hole 11 when the air pressure supply from the upper punching cylinder assembly 8 is insufficient, thus preventing insufficient punching pressure from affecting the subsequent punching quality. A recovery buffer 4 is provided between the center of the bottom mounting cavity 12 and the center of the bottom of the stamping seat 2 to provide buffer protection when the stamping seat 2 falls back, so as to avoid impact damage.

[0048] Furthermore, the stamping seat recovery mechanism 3 includes two stamping seat supports 32 symmetrically distributed on the left and right sides inside the bottom mounting cavity 12. The top surfaces of the two stamping seat supports 32 support the bottom sides of the stamping seat 2, providing stable support for the stamping seat 2 during normal stamping. A pneumatic recovery mechanism 31, installed in the bottom mounting cavity 12, controls the relative movement of the two stamping seat supports 32. Through pneumatic control, the stamping seat supports 32 are driven to extend and retract, realizing the support and recovery operation of the stamping seat 2.

[0049] Furthermore, the pneumatic recovery mechanism 31 includes mounting grooves 311 distributed at the bottom of the bottom mounting cavity 12, providing mounting space for the various components of the pneumatic recovery mechanism 31. A double-headed cylinder 312, installed at the center of the mounting groove 311, serves as the power source for the pneumatic recovery mechanism 31, driving the piston rods 313 on both sides to extend and retract. The piston rods 313, corresponding to the left and right output ends of the double-headed cylinder 312, transmit the power of the double-headed cylinder 312. Slider blocks 314 are installed at the distal ends of the piston rods 313 on both sides, with the top surfaces of the sliders 314 connected to the bottom surfaces of the stamping base supports 32 on both sides, allowing the stamping base supports 32 to move together with the piston rods 313.

[0050] Furthermore, the pneumatic recovery mechanism 31 also includes guide posts 315 installed on the left and right sides inside the mounting groove 311. The guide posts 315 are connected to the slider 314 and guide the movement of the slider 314, enabling it to move smoothly and improving the working stability of the pneumatic recovery mechanism 31.

[0051] Furthermore, the recovery buffer 4 specifically includes the following structures: a spring damper 42 installed at the center of the bottom of the stamping seat 2, which provides cushioning and shock absorption when the stamping seat 2 falls back, preventing impact damage; a buffer support frame 41 installed at the center of the bottom mounting cavity 12, used to cushion and support the falling stamping seat 2; and a central protective plate 43 distributed at the center of the buffer support frame 41, which provides cushioning protection for the double-headed cylinder 312 inside the pneumatic recovery mechanism 31 below when the spring damper 42 falls back with the stamping seat 2, preventing it from directly contacting and being damaged by the spring damper 42.

[0052] Furthermore, an electromagnetic control component 7 is installed on the top surface of the top platform 6, which is connected to the stamping cylinder assembly 8 and the stamping seat recovery mechanism 3. The electromagnetic control component 7 monitors the air pressure output inside the stamping cylinder assembly 8 in real time, thereby automating the support and recovery of the stamping seat 2.

[0053] Furthermore, the electromagnetic control component 7 specifically includes the following structure: a pressure sensor 72 connected to the stamping cylinder assembly 11, which monitors the pressure change of the stamping cylinder assembly 11 in real time. When it detects that the air pressure supply to the stamping cylinder assembly 8 is insufficient, the solenoid valve 71 can be used to stop the downward operation of the stamping cylinder assembly 8. At the same time, the action of the double-headed cylinder 312 is controlled, thereby driving the stamping seat support 32 to perform telescopic movement, which can realize the retraction operation of the stamping seat 2 and avoid the stamping cylinder assembly 8 not stopping the stamping operation, thus affecting the subsequent stamping quality.

[0054] Furthermore, the left and right edges of the bottom of the stamping seat 2 are provided with oblique cuts, and the stamping seat support 32 is set as an inclined slope near the inner side, so that the stamping seat support 32 can match the oblique cuts at the bottom of the stamping seat 2, which facilitates a smooth ejection operation after the stamping seat 2 falls back.

[0055] Furthermore, the base 1 and the top platform 6 are connected by multiple support pillars 13, making the entire device structure more stable and facilitating the assembly of components such as the base 1 and the top platform 6 into a whole.

[0056] The working principle of the embodiment is as follows:

[0057] When the stamping cylinder assembly 8 drives the stamping table 5 to press down, the stamping seat 2 presses the workpiece tightly. At this time, the air pressure sensor 72 senses the pressure change. When the pressure does not reach the preset air pressure, the solenoid valve 71 controls the double-headed cylinder 312 to drive the two side stamping seat supports 32 to move outward. Under the buffer protection of the spring damper 42 and the central protective plate 43, the stamping seat 2 smoothly and completely falls back into the stamping seat recovery hole 11 along the inclined slope of the stamping seat support 32. At this time, even if the upper stamping cylinder assembly 8 continues to drive the stamping table 5 to press down, it will not affect the workpiece on the top surface of the stamping seat 2, ensuring the quality of product stamping and providing a double protection function.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
