This makes the servo press perform well in many high-precision, high-efficiency processing tasks.

[0003] When the servo press is performing processing operations, the operator will use his hands to feed the parts under the pressing head to process the parts. During this process, the operator's fingers may be pressed by the press during the workpiece processing or the process of feeding the parts, causing injury. Therefore, it is necessary to provide a servo press anti-hand pressure mechanism to solve the above problem. Utility Model Content

DETAILED DESCRIPTION

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0020] Specific implementation cases:

[0021] As Figure 1 shown, a hand protection mechanism for a servo press includes a base 1, a working part 2 is installed on the base 1 for pressing down on a workpiece, and a protection part 3 is installed on the working part 2 to protect the hands of workers from being injured when the working part 2 is working;

[0022] The servo press is automatically controlled by a program. The punch below the working part 2 only moves downward, and the protection part 3 adaptively protects the hands of the operator according to the downward movement of the punch.

[0023] As Figure 2 shown, the protection part 3 includes an adjustment mechanism 31, and a protection mechanism 32 is installed below the adjustment mechanism 31;

[0024] The function of the adjustment mechanism 31 is to make its structure more stable when the protection part 3 is working, and at the same time enable the protection mechanism 32 to move along with the movement of the punch of the working part 2. The protection mechanism 32 is the main mechanism to protect the operator's hand from being pressed by the punch during work;

[0025] The adjustment mechanism 31 includes a support block 311, an elastic force adjustment group 312 is installed on the support block 311 for adjusting the up and down movement of the support block 311, a limit plate 314 is slidably installed on the side of the support block 311 for restricting the movement direction of the support block 311, there are two groups of the elastic force adjustment group 312, a connecting rod 313 is installed through the center of the elastic force adjustment group 312, and a connecting plate 315 is installed below the connecting rod 313. The connecting plate 315 is fixedly connected to the protection mechanism 32;

[0026] When the adjustment mechanism 31 is working, the downward movement of the protection mechanism 32 drives the connecting rod 313 installed on the connecting plate 315 to move downward. At the same time, the elastic force adjustment group 312 pulls the support block 311 to move downward along the limit plate 314 until the protection mechanism 32 moves to the designated position. At the same time, the adjustment mechanism 31 can adjust the overall position of the adjustment mechanism 31 through a cylinder to adapt to the different size requirements of different workpieces to be processed. The elastic force adjustment group 312 is a adjustment device mainly composed of a tension spring (not shown in the figure), which is a prior art and will not be elaborated here.

[0027] The protective mechanism 32 includes a surrounding plate 321, the surrounding plate 321 is fixedly connected to the connecting plate 315, a transmission disk 322 is slidably installed at the central axis of the surrounding plate 321, a through hole 323 is provided at the center of the transmission disk 322 for the working punch to pass through, a spring 325 is arranged below the transmission disk 322, the spring 325 is fixedly connected to the surrounding plate 321, a transmission rod tube 327 is installed at the central axis below the transmission disk 322, a bracket 326 is installed below the surrounding plate 321, a baffle 324 is hinged to the upper end of the bracket 326, a contact frame 328 is installed on the transmission rod tube 327, four connecting lugs (not marked in the figure) are arranged on the contact frame 328, a push block 329 is slidably connected to the top ends of the connecting lugs, a chute (not marked in the figure) is arranged at the connection between the push block 329 and the connecting lugs, the chute is inclined at a certain angle, a section of protrusion (not marked in the figure) is arranged on the outer surface of the push block 329, the protrusion is connected to the inner surface of the baffle 324, there is a certain distance between the baffle 324 and the bracket 326, the push block 329 is slidably connected to the bracket 326, and the transmission rod tube 327 is slidably connected to the surrounding plate 321;

[0028] When the protective mechanism 32 is operating, the function of the surrounding plate 321 is to prevent the working part 2 from rolling the operator's hand, sleeve or other sundries into the working part 2 when the working part 2 is pressed down, resulting in injury. When the working part 2 is pressed down, it touches the transmission disk 322, pressing down the transmission disk 322 so that the transmission disk 322 slides downward in the surrounding plate 321, the spring 325 contracts, driving the transmission rod tube 327 to move downward. At the same time, the contact frame 328 installed on the transmission rod tube 327 is pressed down accordingly, pushing the push block 329 along the inclined chute on the push block 329 outward along the bracket 326. The protrusion arranged on the push block 329 pushes the baffle 324 outward. Since the upper end of the baffle 324 is hinged to the bracket 326, the baffle 324 will turn outward along the rotation axis at the connection with the bracket 326, pushing away the objects outside the baffle 324, including the operator's hand for holding the workpiece, away from the processing punch. The adjusting mechanism 31 can also adaptively drive the protective mechanism 32 to move to a suitable position away from the workpiece when the working part 2 is pressed down, and there is a maximum movement distance. After the processing is completed, the spring 325 in the protective mechanism 32 adaptively bounces back to its original position, and the elastic force adjusting group 312 in the adjusting mechanism 31 also returns to its original position. The function of the through hole 323 arranged in the protective mechanism 32 is to enable the punch to pass through the through hole 323 to work on the workpiece;

[0029] To summarize, by pressing down the working part 2, the adjusting mechanism 31 adaptively drives the protective mechanism 32 to move to a suitable position away from the workpiece, and at the same time, the working part 2 contacts the transmission disk 322, and pressing down the transmission disk 322 causes the transmission disk 322 to slide downward in the enclosure 321, driving the transmission rod tube 327 to slide downward, and the contact frame 328 installed thereon pushes the push block 329 outward, and the push block 329 pushes the baffle 324 outward, and the baffle 324 pushes objects on its outside, including the operator's hands for picking up the workpiece, away from the processing pressure head, so as to prevent the operator's hands from being pressed when the working part 2 is working. By setting the enclosure 321, it can prevent the operator's hands or sleeves and other debris from being rolled into the working part 2 when the working part 2 is pressed down, thereby causing injury.

[0030] The above is only a preferred implementation of the present application. The protection scope of the present application is not limited to the above embodiments. All technical solutions under this idea belong to the protection scope of the present application. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present application should also be regarded as the protection scope of the present application.
