Problems solved by technology

[0002] The long-rectangular hydraulic punching machine is used for processing a large number of groups of holes. It is widely used in construction, shipbuilding and other fields. It can punch dozens of holes at the same time. The efficiency is very high. The long-rectangular hydraulic punching machine has Dozens of punching pins, but currently each punching pin is fastened separately by a gland and two fastening bolts. When installing or replacing the punching pins of the punching machine, a large number of bolts need to be removed, and the workload is heavy. The working efficiency of the equipment is reduced, so it is particularly important to develop a device that can quickly install and replace the punching needle for the convenience of the punching machine

Embodiment Construction

[0014] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0015] Such as figure 1 It is a schematic diagram of the structure of the present invention, a quick installation device for punching needles of a long platform hydraulic punching machine. 7. The upper support plate 2 is installed on the tool holder 1, the punch 6 is pressed on the tool holder 1 through the pressure plate 4 and the fastening bolt 5, the plug 3 is placed between the pressure plate 4 and the upper support plate 2, and the lower Mold 7 is installed on the workbench. Said pressing plate 4 is processed with semicircular holes for installing punching pins, and the number of semicircular holes on one pressing plate 4 is 1-8. A plurality of punching pins are arranged as a group and installed at the same time, which greatly simplifies the installation steps and saves installation time. The plug 3 is designed as a semicircle, and a handle is processe...

Abstract

The invention provides a rapid mounting device for punching needles of a long rectangular table hydraulic punching machine. The device comprises a knife rest, an upper supporting plate, a plug block,a pressing plate, fastening bolts, the punching needles and a lower mold; the upper supporting plate is arranged on the knife rest, the punching needles are pressed on the knife rest through the pressing plate and the fastening bolts, the plug block is placed between the pressing plate and the upper supporting plate, and the lower mold is arranged on a worktable. Semi-circular holes for mounting of the punching needles are formed in the pressing plate, one to eight semi-circular holes are formed in one pressing plate, the multiple punching needles are arranged in one group and are simultaneously mounted, the mounting step is greatly simplified, mounting time is saved, the plug block is designed to be in a semi-circular shape, and a handle is machined at one end of the plug block. The device is compact in structure, easy to popularize and good in economic benefit.

Description

technical field [0001] The invention relates to an auxiliary device for a punching machine, in particular to a quick installation device for punching needles of a hydraulic punching machine with a long rectangular platform. Background technique [0002] The long-rectangular hydraulic punching machine is used for processing a large number of groups of holes. It is widely used in construction, shipbuilding and other fields. It can punch dozens of holes at the same time. The efficiency is very high. The long-rectangular hydraulic punching machine has Dozens of punching pins, but currently each punching pin is fastened separately by a gland and two fastening bolts. When installing or replacing the punching pins of the punching machine, a large number of bolts need to be removed, and the workload is heavy. The work efficiency of equipment has been reduced, therefore, it is particularly important to develop a kind of device that can install and change punching needle quickly to th...
