AI Technical Summary
The guide rails of existing stamping presses are prone to deformation when bearing the cutting force of the cutter, which leads to instability of the device.
An automatic lowering device for the lifting pad is adopted. The lifting pad is raised by a side-push cylinder and a wheel-shifting oblique push mechanism. The pressure is transmitted to the lifting fixed plate by the wheel-shifting oblique push mechanism. Combined with the tension spring and the lifting guide sleeve, the pad is automatically lowered, avoiding the guide rail from directly bearing the pressure.
It effectively supports the cutting force of the cutter, prevents guide rail deformation, and improves the stability and service life of the device.

Description
TECHNICAL FIELD
[0001] The utility model relates to punch press technical field, concretely relates to a jacking base plate automatic back falling device. BACKGROUND
[0002] The punch press is a device used for cutting standard test pieces before tension test in enterprises or scientific research units.
[0003] The punch press is usually fixed and installed on the bearing surface of the workbench by several bolts. When cutting the test pieces, the corresponding cutter is selected according to different samples and installed on the position of the pressing plate of the machine. Then the material is placed on the cutter pad, the lead screw is moved downward, and the cutter contacts the material. The control knob is rotated toward the sample pressing direction and tightened. The operating lever is moved up and down by hand, and the lower pressing plate is moved upward. After the sample pressing is completed, the control knob is rotated toward the reset direction, and the lower pressing plate is automatically reset.
[0004] The existing improved punch press is shown in the drawings. The upper pressing plate is provided with a cylinder, and the bottom of the lower pressing plate is provided with a guide rail. The displacement of the lower pressing plate is realized through the guide rail, so as to facilitate the feeding of the rubber plate. The lower pressing plate is driven downward by the cylinder, so that the cutter fixed on the upper pressing plate cuts the rubber plate fixed on the lower pressing plate. However, due to the limited bearing capacity of the guide rail, the cutter cutting is easy to cause the deformation of the guide rail, so there is an urgent need for a device that can bear the cutting force of the cutter during the pressing process. Figure 5 TECHNICAL SOLUTION The utility model provides a jacking base plate automatic back falling device which provides support for the lower pressing plate.

The side surface of the jacking fixed plate is provided with a second tension spring mounting part corresponding to the first tension spring mounting part. A tension spring is assembled between the first tension spring mounting part and the second tension spring mounting part. The side pushing cylinder pushes the wheel moving and inclined pushing mechanism. The wheel moving and inclined pushing mechanism pushes the jacking base plate upward. The jacking base plate becomes the bottom support of the lower pressing plate after being lifted. After the side pushing cylinder returns to the original position, the jacking base plate falls back to the initial position under the action of the tension spring.
