Description

Press cold breaking device

technical field

The utility model relates to a cold breaking material device for a press used in the blanking process of metal machining.

Background technique

Stamping is a blanking process used in metal machining. At present, the severing of metal bars generally adopts the method of pre-processing a gap at the truncation of the metal bar, and then using the stress concentration effect to stamp and truncate. The initial gap processing is labor-intensive and time-consuming, which increases the cost of the blanking process and reduces the efficiency.

Contents of the invention

The purpose of this utility model is to solve the above problems, to provide a kind of press cold-broken material that uses the stress concentration effect to cut and blank the metal bar, which saves labor and time, can effectively reduce the cost of the blanking process, and improve work efficiency. device.

The technical solution to achieve the above purpose is: a press cold breaking material device, which has a base plate, a fixed-length stopper is arranged on one side on the base plate, and a notch knife rest is arranged on the other side. A fulcrum seat is arranged in the middle of the ruler stopper and the notch knife rest, a notch knife is equipped on the top of the notch knife rest, and a fulcrum body is assembled on the fulcrum seat.

The technical scheme of the utility model also includes: a notch knife bead is arranged on the side of the knife holder corresponding to the notch knife, and a notch knife adjustment screw is arranged on the top of the knife rest; the fulcrum body is a multi-prism steel bar, The pressing plates placed on the two ends above are fixed on the fulcrum seat.

The utility model utilizes the configured notch knife to complete the processing of the broken notch while punching and blanking the bar stock. Compared with the previous method of bar stock blanking that needs to be processed in advance, it saves labor and time, and can greatly reduce the cost. Reduce the cost of blanking process and improve work efficiency.

Description of drawings

The accompanying drawing is a structural schematic diagram of the cold breaking material device of the press.

Detailed ways

The specific embodiment of the utility model will be described in conjunction with the accompanying drawings.

As shown in the accompanying drawings, the press cold breaking material device has a base plate 1, on which a fixed-length stop 2 is arranged on one side, and a notch knife rest 5 is arranged on the other side, and a fixed-length stop is arranged on the other side. A fulcrum seat 3 is arranged in the middle of the notch knife rest, a notch knife 6 is assembled on the top of the notch knife rest, and a fulcrum body 4 is assembled on the fulcrum seat. The side of the knife holder is arranged with the knife holder to be provided with the bead knife bead 7 connected by screws, and the knife holder is provided with the adjustment screw 8 of the knife holder. Its fulcrum body 4 is a square prism steel bar, is fixed on the top of the fulcrum seat by two pressing plates 9 connected through screws that place two ends above it.

When the utility model is in use, it is installed on the workbench of the stamping machine, and the bar material 10 is fed into the front end to contact with the fixed-length stopper. The upper edge of the prismatic steel bar) corresponds to the downward punching of the punch 11 of the punching machine, so that the bar is cracked at the gap until it breaks, that is, the cutting and blanking of a section of the bar is completed. When the bar is broken, under the action of the reaction force, the notch knife cuts a gap on the bar to form a cut-off gap for the next section of bar, which can continue to cut off the material again and again.

When the utility model is actually implemented, the fixed-length stopper 2, the notch knife rest 5 and the base plate 1 are connected and fixed by bolts configured with T-shaped grooves, so as to facilitate the adjustment of the length of the cut material.

The applicable bars of the utility model can be solid sections such as circles, squares, rectangles, and hexagons, and can also be steel rails close to solid sections. Bar material can be steel or non-ferrous metal material with mechanical properties close to steel.
