detailed description

A horizontal cutting machine, as shown in Figures 1 to 3, comprising: a fixed knife 1, a support 2, an adjusting bolt 3, a push rod 4, a cylindrical helical compression spring 5, a raw material 6, a positioning screw 7, and a positioning screw seat 8. Cutting knife 9, T-bolt 10, guide sleeve 11, wherein:

The fixed knife 1 is installed on the bed, the support 2 is installed on the fixed knife 1, and the adjusting bolt 3 is installed on the ejector rod 4, which is used to adjust the relative position of the ejector rod 4 and the raw material 6. The ejector rod 4 is installed on the support with clearance fit. In the seat 2, the cylindrical helical compression spring 5 is installed in the ejector rod 4. The raw material 6 passes through the guide sleeve 11 and reaches the positioning screw 7 via the fixed knife 1. After being positioned, it is cut off by the cutting knife 9. The positioning screw 7 is installed on the positioning screw seat 8. Can realize the adjustment of the length of the cutting material, the positioning screw seat 8 is installed on the bed, the cutting knife 9 is installed on the bed slider through the T-bolt 10, and the guide sleeve 11 is installed on the fixed knife 1.

The working principle of the utility model is: by adjusting the relative position of the adjusting bolt 3 on the ejector rod 4, the compression degree of the cylindrical helical compression spring 5 is changed, thereby changing the relative position of the adjusting ejector rod 4 and the raw material 6 to achieve the adjustment of the ejector rod 4 The purpose of adjusting the pressing force of the raw material 6 is to ensure the force balance of the raw material 6 in the cutting process, so that the cut can achieve excellent cutting quality.

As shown in Fig. 6 and Fig. 7, this device processes an inclined slope on the cutting surface of the cutting edge of the fixed knife 1 along the upper and lower directions, so as to facilitate better adjustment and the gap between the cutting knife 9 (the smaller the gap, the smaller the gap. The better the cutting quality), the better to ensure the cutting quality of the product; a tapered guide port is set at the feed port position of the fixed knife 1, which can better ensure the feeding accuracy of the raw material 6; at the same time, the fixed knife 1 A countersunk groove is processed at the lower end for the positioning of the support 2, thereby ensuring the accuracy of the relative position of the ejector rod 4 and the raw material 6.

As shown in Figures 4 and 5, the cutting edge of the cutting knife 9 is improved accordingly, and a semicircular countersunk knife edge is used. The countersunk knife edge reduces the contact area between the cutting knife and the raw material 6, so that the shearing in the cutting process The force is more concentrated, which better guarantees the cutting quality.

Through the improvement of the fixed knife 1 and the cutting knife 9, and the design of a set of pressing device composed of the support 2, the adjusting bolt 3, the ejector rod 4 and the cylindrical helical compression spring 5, the fixed knife can be fixed during the whole cutting process. 1 is always in close contact with the cutting surface of the cutting knife 9; at the same time, due to the compression of the cylindrical helical compression spring 5, the adjusting push rod 4 always exerts a certain extrusion force on the raw material 6, thereby ensuring The force balance of the raw material 6 during the cutting process finally makes the cutting edge reach an excellent cutting quality.

This device improves the cutting quality of the product, the fracture is flat, the verticality is excellent, the burrs and flashes are small, and the cutting quality required by the product is achieved.
