Abstract
Description
Technical Field
[0001] This utility model relates to a safety protection device for band saws, belonging to the field of mechanical processing technology. Background Technology
[0002] A band saw is a device used for end sawing of steel that has undergone heat treatment or been machined. It can perform precise cuts according to different requirements, ensuring the size and accuracy of the cuts.
[0003] During production with the existing equipment, there is a risk of saw blade breakage on the band saw. When the saw blade breaks off, it flies out and injures workers, endangering their personal safety. Summary of the Invention
[0004] The technical problem to be solved by this utility model is to provide a safety protection device for band saws that is simple in structure, easy to operate, and prevents the saw blade from flying out and injuring workers when it breaks.
[0005] The technical solution adopted by this utility model to solve the above problems is as follows: a safety protection device for a band saw includes two fixed plates arranged at intervals on the left and right, the fixed plates being fixed to the band saw; a positioning unit symmetrically arranged front and back is provided between the two fixed plates, the two ends of the positioning unit being fixedly connected to the fixed plates respectively; the gap between the two positioning units forms a storage cavity, and multiple side-by-side baffles are inserted into the storage cavity, with the bottom of the baffles supported on the band saw; multiple evenly distributed positioning holes are opened on the positioning unit, and vertically arranged waist-shaped holes are opened on the baffles respectively, the positioning holes corresponding to the waist-shaped holes, and positioning pins horizontally passing through the positioning holes and waist-shaped holes, so that the baffles can move up and down along the waist-shaped holes in the storage groove.
[0006] Each of the positioning units includes two horizontally arranged positioning plates, each with a plurality of positioning holes, which are evenly spaced along the length of the positioning plate.
[0007] The width of the storage cavity is greater than the thickness of the baffle.
[0008] The distance between the positioning hole on the bottom positioning plate and the inner wall of the bottom of the waist-shaped hole is greater than the diameter of the rod.
[0009] The baffle is made of plexiglass.
[0010] Compared with existing technologies, the advantages of this utility model are as follows: A safety protection device for a band saw, wherein the baffle can move up and down along the oblong hole in the storage slot. During sawing, the operator moves the baffle upward, causing the end of the bar to extend out; the operator is on one side of the baffle, and the band saw blade is on the other side of the baffle. This application has a simple structure and is easy to operate; it allows observation of the sawing process while completely blocking the band saw blade, effectively solving the safety hazard of personnel being injured by the potentially broken and flying saw blade.

[0012] Figure 2 for Figure 1 Top view;
[0013] Figure 3 for Figure 1 A diagram illustrating the working status;
[0014] In the figure, 1 is a fixing plate, 2 is a positioning plate, 3 is a baffle, 4 is a waist-shaped hole, 5 is a positioning pin, and 6 is a bar. Detailed Implementation
[0015] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.
[0016] like Figure 1 , 2 As shown in Figure 3, a safety protection device for a band saw in this embodiment includes two fixed plates 1 arranged at intervals on the left and right sides, which are fixed to the band saw. A positioning unit is symmetrically arranged between the two fixed plates 1, with both ends of the positioning unit fixedly connected to the fixed plates 1. The gap between the two positioning units forms a storage cavity, in which multiple side-by-side baffles 3 are inserted, with the bottom of the baffles 3 supported on the band saw. Each positioning unit includes two horizontally arranged positioning plates 2, each with multiple positioning holes evenly distributed along the length of the positioning plate 2. Vertically arranged oblong holes 4 are formed on each baffle 3, with the positioning holes corresponding to the oblong holes. A positioning pin 5 passes horizontally through the corresponding positioning holes and oblong holes, allowing the baffle to move up and down along the oblong holes within the storage groove, and the positioning pin also limits the movement of the baffle, preventing it from moving out of the storage cavity.
[0017] The width of the storage cavity is slightly larger than the thickness of the baffle to ensure minimal resistance when the baffle moves up and down.
[0018] The distance between the positioning hole on the bottom positioning plate and the inner wall of the bottom of the oblong hole is greater than the diameter of the bar. During sawing, the baffle is moved upward to allow the end of the bar to extend out, facilitating sawing.
[0019] The aforementioned baffle is made of plexiglass. The operator is positioned on one side of the baffle, while the band saw blade is on the other side. This allows the operator to observe the sawing process while completely blocking the band saw blade, effectively eliminating the safety hazard of personnel being injured by a potentially broken or flying band saw blade.
[0020] In addition to the above embodiments, this utility model also includes other implementation methods. All technical solutions formed by equivalent transformation or equivalent substitution should fall within the protection scope of the claims of this utility model.
