Detailed ways

The utility model will be further described in detail below in conjunction with the examples, but the implementation of the utility model is not limited thereto.

Example 1:

A U-shaped steel cutter mold, as shown in Figures 1 to 7, includes a feed assembly and a discharge assembly that allow U-shaped steel 10 to pass through, and a cutter is also arranged between the feed assembly and the discharge assembly, so The cutter is provided with a blade that can directly cut off the U-shaped steel 10, the feeding assembly includes a shell plate a21, and the shell plate a21 is provided with a passage hole a22 that allows the U-shaped steel 10 to pass through, and the discharging assembly includes a shell plate a21. A plate b41, the shell plate b41 is provided with a passage hole b42 through which the U-shaped steel 10 can pass.

Specific implementation method: U-shaped steel 10 is sequentially passed through the passage hole a22 of the feed assembly and the passage hole b42 of the discharge assembly, and the shell plate a21 and shell plate b41 are moved to the position that needs to be cut off, and the cutting knife is left Under the push of the hydraulic cylinder, the cutting knife cuts the U-shaped steel 10 downwards. After the U-shaped steel 10 is cut, take the U-shaped steel 10 out of the passage hole b42 of the discharge assembly to complete the entire cutting process. The structure of the device is simple. However, the cutting efficiency is high, and it does not require more manpower and material resources, which greatly saves the production cost and maintenance cost of the enterprise.

Example 2:

This embodiment is further optimized on the basis of the foregoing embodiments, as shown in Figure 1, the cross-sectional shape of the passing hole a22 and the passing hole b42 is consistent with the cross-sectional shape of the U-shaped steel 10; the width of the passing hole a22 Less than the width of the passing hole b42, the height of the passing hole a22 is less than the height of the passing hole b42; the width of the passing hole a22 is 1-5mm less than the width of the passing hole b42, and the height of the passing hole a22 is 1-5mm less than the height of the passing hole b42 ; The width of the passage hole a22 is less than 2mm of the width of the passage hole b42, and the height of the passage hole a22 is less than the height of the passage hole b42 of 2mm.

The specific implementation of adding the above technical features: In order to make the practicability of this mold more specific, the shapes of the passing hole a22 and the passing hole b42 are set to be the same as the shape of the U-shaped steel 10. The shaped steel 10 can be smoothly removed from the discharge assembly, so the width and height between the passing hole a22 and the passing hole b42 are more limited. During the cutting process of the U-shaped steel 10 by the cutter, burrs are likely to occur. Because the burr has a certain rigidity, it will be very time-consuming and laborious to process. If time is wasted here, it will greatly affect the production efficiency, and the width and height of the passing hole a22 are smaller than the width and height of the passing hole b42. , it can solve this technical problem to a certain extent, but the passage hole a22 cannot be smaller than the passage hole, and the passage hole b42 is too large, which is not conducive to the cooperation between the U-shaped steel 10 and the cutter, and the degree of cooperation is reduced. Often, long-term tests are obtained. It can be seen that when the width and height of the passage hole a22 are all smaller than the width and height of the passage hole b42 by 1-5mm, it is most suitable, preferably 2mm, because the burr will not be too long or too short, so this size is the best , can improve work efficiency while ensuring product coordination.

Other parts of this embodiment are the same as those of Embodiment 1 above, and will not be repeated here.

Example 3:

This embodiment is further optimized on the basis of the above embodiments. As shown in Figure 2, the cutter includes a handle 31, and the bottom of the handle 31 is provided with a blade, and the blade includes a blade a32, a blade b33 and a blade c34, the blade a32, the blade b33 and the blade c34 are all concave blades, the blade b33 is between the blade a32 and the blade c34, and the installation positions of the blade a32 and the blade c34 are symmetrical; the concave curvature of the blade b33 is 30°.

The specific implementation manner of increasing the above-mentioned technical features: this device is a mold for cutting the U-shaped steel 10, and in order to improve the efficiency of cutting, the cutting knife mainly includes a knife handle 31, and the bottom of the knife handle 31 is provided with a blade. There are 3 blades, namely blade a32, blade b33, and blade c34. In order to better fit the U-shaped steel 10, the blade a32, blade b33, and blade c34 are all set as concave blades, and they are arc-shaped. At the same time, the blade a32 and the blade The shape and structure of b33 are the same, but the installation positions are relatively symmetrical. The blade b33 is arranged between the blade a32 and the blade c34, and the inwardly concave curvature is 30°. During the implementation, the cutter is directly moved to the U-shaped steel 10, and the blade a32 and blade c34 are respectively in contact with the end face of U-shaped steel 10, and blade b33 extends into the gap of U-shaped steel 10, and is pushed down by the hydraulic cylinder to cut off. At the same time, in order to improve efficiency, the blade b33 is The concave curvature is set to 30°, and the curvature on the blade a32 and blade c34 is set to 35°. This angle, through long-term tests, can quickly contact the knife U-shaped steel 10 during the cutting process, and the setting of this angle not only It can improve work efficiency and reduce the loss of blades.

Other parts of this embodiment are the same as those of Embodiment 1 above, and will not be repeated here.

Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that: without departing from the principle and purpose of the present invention, various changes, modifications, substitutions and modifications can be made to these embodiments , the scope of the present invention is defined by the claims and their equivalents.
