Description

Clamping device on the punch former

technical field

The invention relates to a clamp device on a punch former, belonging to the technical field of mechanical processing equipment.

Background technique

In the existing grinding technology, it is often encountered that only a bar with a maximum diameter of 20MM can be processed on a specific punch former, so that it can only be processed outside, resulting in relatively high costs; and when the length of the processed bar is 150mm ~200MM, and when both ends of the rod need to be processed, it often happens that the workpiece needs to be removed halfway and re-clamped, which wastes time and energy and low efficiency.

Contents of the invention

The purpose of the present invention is to overcome the above disadvantages, so as to provide a clamp device on the punch former, which does not need to take off the parts and re-clamp during the grinding process, so that the whole working process is very simple, safe to use, and can be greatly improved. Significantly improve production efficiency and reduce production costs.

According to the technical solution provided by the present invention, the clamp device on the punch former includes a first fixing plate, a second fixing plate and an iron magnet, and the first fixing block and the second fixing block are respectively clamped on both ends of the iron absorption. Inside the groove, fix it on the head of the punch former with four fastening screws, and the suction iron is connected with the first fixed block and the second fixed block.

Compared with the prior art, the present invention has the following advantages:

The invention has a simple, compact and reasonable structure; it can process coaxial parts and relatively large outer circles; the working process is very simple and safe; and the processing efficiency can be greatly improved.

Fig. 2 is a schematic top view of the structure of the mold in the separated state of the present invention.

Detailed ways

Below the present invention will be further described in conjunction with the embodiment in the accompanying drawing:

As shown in FIGS. 1-2 : it includes a fixed plate 1 , a fixed plate 2 , an iron magnet 3 and a punch former 4 .

The present invention adopts the fixed block 1 and the fixed block 2 to be respectively stuck in the grooves at both ends of the suction iron, and then fixed on the head of the punch former 4 with four fastening screws, the suction iron 3 and the fixed block 1 and the fixed block 2 connected. Need to increase a base plate at the bottom of punch former 4, be in order to increase the processing stroke of workpiece. The base plate is fixed on the bottom of the punch former 4 with fastening screws.

Working principle and working process of the present invention:

First, fix the fixture device on the head of the punch forming with fastening screws, then suck the bottom plate on the working table of the grinder, adjust it to a horizontal position, then fix the punch former on the bottom plate with screws, and suck the workpiece on the suction On the iron, use a dial indicator to adjust the workpiece and the punch former to the concentric position. At this time, turn on the grinding wheel on the grinder to perform tool calibration on the part of the workpiece that needs to be processed, and then manually shake the handle on the punch former to fine-tune the grinder. Switch to make the workpiece and the grinding wheel rotate at a low speed, and grind to the required size.

The invention fixes the head of the punch former by fastening screws, so that the outer diameter of the processed workpiece can reach 75MM at most, and there is no need to remove the part and re-clamp it during the grinding process, so that the whole working process is very convenient and easy to use. Safety, can greatly improve production efficiency and cost control.
