Description

A spring strip cutting device capable of automatically removing raw material heads

technical field

The utility model relates to an elastic strip cutting device which can automatically remove raw material ends.

Background technique

The clip cutting process needs to cut each 9-meter-long raw material into short pieces that meet the required size, and at the same time, the head part of the 9-meter-long raw material must be removed first. The traditional way of removing the material head is manual control, and the workers control the length of the head by experience. Since each 9-meter-long raw material is fed by an automatic feeding wheel, the worker removes the head. It is necessary to pull the 9-meter-long raw material with force, and only let the material head part expose the cutting edge and keep it for a period of time to remove the material head. The labor intensity is high, the production efficiency is low and the degree of automation is not high, and there is often no control due to human reasons. The length of the good head leads to the waste of raw materials.

detailed description

A spring strip cutting device capable of automatically removing raw material heads, as shown in Figure 1 and Figure 2, comprising: a bottom plate 1, a lower knife seat 2, a lower knife fixing plate 3, a slider 4, a guide rail 5, and a cylinder fixing plate 6 , cylinder 7, cylindrical compression spring 8, guide pin 9, limit block 10, lower knife 11, upper knife 12, upper knife seat 13, left limit block support 14, left limit block 15, guide sleeve 16, Adjust the bolt 17 , the fixing seat 18 , the first fixing plate 19 , the second fixing plate 20 and the right limit block 21 .

Wherein, the bottom plate 1 is installed on the workbench of the cutting machine, the lower knife seat 2 is installed on the bottom plate 1, the lower knife fixing plate 3 is installed on the lower knife seat 2, and the lower knife 11 is fixed, and the slider 4 (shape and The structure is shown in Figure 3) is installed on the cylinder 7, and the cylinder 7 drives the slider 4 to move horizontally back and forth under the guidance of the guide rail 5 (shape and structure shown in Figure 4). The guide rail 5 is installed on the bottom plate 1, and the cylinder The fixed plate 6 (shape and structure shown in Figure 6) is welded on the guide rail 5 to fix the cylinder 7, and the cylindrical compression spring 8 is installed directly below the limit block 10 (shape and structure shown in Figure 7), guiding The pin 9 (shape and structure shown in Figure 6) is installed in the cylindrical compression spring 8 and fixed in the slider 4, and the limit block 10 is guided by the cylindrical compression spring under the joint guidance of the guide pin 9 and the slider 4 The elastic force of 8 and the pressure of cutting machine move vertically up and down, and the lower knife 11 and the upper knife 12 are installed on the lower knife seat 2 and the upper knife seat 13 respectively.

Bearing 14 is installed on the base plate 1, and left stop block 15 (shape and structure as shown in Figure 8) is installed on the support 14, plays the left limit action to the short material after cutting off, and guide sleeve 16 ( Shape and structure shown in Figure 9) are installed on the adjusting bolt 17, and the adjusting bolt 17 is installed on the fixed seat 18, and the length adjustment effect is played on the cutting material, the first fixed plate 19 is installed on the base plate 1, and the second fixed plate 20 Welded on the first fixed plate 19, the right limit block 21 (shape and structure as shown in Figure 10) is installed on the second fixed plate 20, and acts as a right limit to the short pieces after cutting.

Fig. 11 is a partial assembly diagram of the bottom plate 1, the support 14, the left limiting block 15, the first fixing plate 19, the second fixing plate 20 and the right limiting block 21 of the device. On the assembly drawing after assembly, there is an arc-shaped trajectory extending to the other end of the first fixing plate 19, and an opening is processed inside the first fixing plate 19, and the arc-shaped trajectory is used for cutting off the formed The discharge port for short materials of the same size, and the short materials of the same size roll down from the discharge port to the material rack.
