Description

Technical Field

[0001] The utility model relates to the technical field of plate cutting, in particular to a lead plate bevel cutting device. Background Art

Pipeline radiation protection is shielded by wrapping concrete (vibrated and compacted) or external lead plates. In order to protect the health of medical staff and patients from the effects of radiation, nuclear medical wastewater pipes must be shielded with lead plates. Conventional practices result in loose splicing of lead plates, blank spaces, and poor bonding between lead plates and pipes, resulting in the risk of external lead plates falling off over time.

[0003] According to the pipe diameter and length, the cutting size of the lead plate is calculated, and then it is cut into uniform size bevels, which can not only make the lead plates combine well with each other, but also greatly reduce the waste of lead plates. Utility Model Content

[0013] The technical solution of the utility model is described in detail below with reference to the accompanying drawings, but the protection scope of the utility model is not limited to the embodiments.

[0014] Reference Figure 1 and Figure 2 The utility model discloses a lead plate bevel cutting device, comprising two parallel long channel steels 1 and short channel steels 2, a scale 3 parallel to the long channel steel 1 is fixedly arranged at the bottom of the short channel steel 2, the openings of the two channel steels are arranged opposite to each other, a flat iron 4 is arranged between the two channel steels, the two ends of the flat iron 4 are respectively fixed on the webs of the two channel steels, cutting knives 5 are arranged on both sides of the web of the long channel steel 1 close to the flat iron 4, the cutting knives 5 can move left and right and up and down, the cutting knives 5 can overlap on the scale 3 within the rotation stroke, the bottom height of the flat iron 4 is lower than the bottom height of the two cutting knives 5, in the utility model, the lead plate material to be used is first placed in the two side-lying channel steels, the lead plate material is located on one side of the flat iron 4, the lead plate material is moved along the two channel steel wing plates toward the flat iron 4 until it abuts against the flat iron 4, at this time, since the bottom height of the flat iron 4 is lower than the bottom height of the two cutting knives 5 The bottom height, so the height of the cutting knife 5 is higher than the height of the lead plate so that the cutting knife 5 can move down to cut the plate. Since the flat iron 4, the cutting knife 5 and the ruler 3 form a right triangle, the length of the flat iron 4 is measured before the utility model is assembled, and then the length of the tail of the cutting knife 5 from the flat iron 4 is measured by the ruler 3 to obtain the two right-angled sides of the right triangle. Therefore, the length of the hypotenuse after the plate is cut can be calculated. When the lengths of the three sides of the right triangle are known, it is easy to get the angles of the other two angles of the triangle. Therefore, according to the angle of the plate to be cut, the side length of the right triangle can be deduced, and one of the side lengths is the left and right moving distance of the cutting knife 5, which is intuitively called out by the ruler 3. Since the utility model is provided with cutting knives 5 on both sides of the flat iron 4, the utility model can simultaneously perform plate cutting work on both sides of the flat iron 4, and the work efficiency is high.

[0015] In the utility model, a "0" scale is set on the scale ruler 3, and the flat iron 4 is located at one end of the short channel steel 2 and is placed on the "0" scale. This technical solution can intuitively see the cutting length of the bottom of the plate without calculating through the scale ruler 3.

[0016] In addition, the two ends of the flat iron 4 are fixedly connected to the two channel steels by welding to ensure the strength of the plate against the flat iron 4. The cutting knife 5 is fixed to the web of the long channel steel 1 by a universal ball connection to ensure the freedom of the cutting knife 5. Of course, the utility model can realize the rotation of the cutting knife 5 through other technical solutions, which are all within the protection scope of the utility model.

[0017] Preferably, the length of the bottom wing plate of the short channel steel 2 is shorter than that of the upper wing plate, and the rear end of the scale 3 is welded and fixed to the bottom wing plate. The scale 3 serves as an extension of the length of the bottom wing plate of the short channel steel 2. This technical solution can make the scale 3 flush with the bottom of the short channel steel 2, so that there is no gap between the bottom of the plate and the scale 3, thereby ensuring the cutting accuracy.

[0018] As above, although the utility model has been shown and described with reference to a specific preferred embodiment, it should not be interpreted as limiting the utility model itself. Various changes can be made to it in form and detail without departing from the spirit and scope of the utility model defined in the attached claims.
