Title:
PUNCHING DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/102882
Kind Code:
A1
Abstract:
A punching device, comprising a box body (1); the upper surface of the box body (1) is recessed inward to form a groove (2), liquid storage tanks (14) are provided at two sides inside the box body (1), a high-pressure pump (3) is provided inside each liquid storage tank (14), a water outlet of each high-pressure pump (3) is in communication with each spray head (4) provided on the upper surface of the box body (1), liquid return ports (5) in communication with the liquid storage tanks (14) are provided on the upper surface of the box body (1), and a rotary disk (6) and a supporting block (7) fixed at the middle of the rotary disk (6) are provided in the middle of the upper surface of the box body (1). By means of the arrangement of adjustment devices (11), said device can adjust the position of an electric drill according to the structural requirements of a member to be punched, thereby adapting to the requirements of surface punching for different diameters and widths; two holes may be punched simultaneously, or only one hole may be punched as required, having strong operability and high punching efficiency. Moreover, in the punching process, the temperature at the punching position of the member to be machined can be reduced, avoiding unqualified punched holes caused by an excessively high temperature; and recycling of cooling liquid can be achieved by means of the cooperation of the liquid return ports (5), the liquid storage tanks (14), the high-pressure pumps (3) and filters (13), and thus said device has a high utilization efficiency.
