Description

Technical Field

[0001] The invention relates to the technical field of bar cutting, and more specifically to an industrial hardware bar cutting device. Background Art

[0002] Bars generally refer to simple cross-section profiles, with a relatively large ratio of length to cross-section circumference and no obvious convex or concave parts in the cross section. They are straight strip products made of metal plastic processing. They are also called bars or ordinary cross-section profiles, including square, round, flat and hexagonal profiles. Simple cross-section steel generally includes the following varieties: Square steel: The cross-sectional shape is square, and its specifications are expressed by the size of the side length. There are pointed square steel and rounded square steel. The latter is generally used as billet for medium and small rolling mills. The common specifications are 5.5 to 200 mm. It can be used to manufacture parts of various equipment, fences, etc. Round steel, the specifications are expressed by the diameter size. The common round steel diameter is 5.5 to 250 mm. In China, round steel below 10 mm is usually called wire. Round steel with a diameter of 10 to 25 mm is a commonly used construction steel bar, and is also used to make bolts and other parts. Round steel with a diameter greater than 30 mm is used to make various mechanical parts; Flat steel: The cross-sectional shape is rectangular, and the specifications are expressed in thickness and width. The thickness is generally 5 to 60 mm, and the width is generally 10 to 150 mm. It is mostly used in welding pipe billets and machinery manufacturing industries; Hexagonal steel: The specifications are expressed in the distance between the opposite sides of the hexagon. The commonly produced hexagonal steel has a distance between opposite sides of 8 to 70 mm, and is mostly used to make nuts and various tools; Triangular steel: Bow steel and oval steel. These steels are mostly used to produce files, which are small-sized steels, and the general cross-sectional size is not more than 30 mm; Angle steel: There are two types of equal-leg angle steel and unequal-leg angle steel. The specifications of equal-leg angle steel are expressed in side length and side thickness. The commonly used equal-leg angle steel has a side length of 20 to 200 mm and a side thickness of 3 to 24 mm. The specifications of unequal-leg angle steel are expressed in the length and thickness of the long and short sides.

[0011] In a preferred embodiment, the number of the limiting ribs is two groups, and the two groups of limiting ribs are arranged in an axisymmetric manner with respect to the vertical center axis of the contact pad.

[0012] Technical effects and advantages of the present invention: 1. When the cutter rotates, the cutting edge contacts and grinds with the inner walls of the first contact ring and the second grinding ring, so that the cutting edge is slightly ground once when it rotates rapidly away from the cutting and truncation of the bar body. Three groups of first contact rings and second grinding rings are arranged on the outer walls of the first reinforcing rib, the second reinforcing rib, the third reinforcing rib, the fourth reinforcing rib and the fifth reinforcing rib, so that the cutting edge is slightly ground three times when it rotates out of the cutting and truncation, and at the same time, the inner walls of the first contact ring and the second grinding ring are prevented from contacting and grinding with the cutting edge for a long time, causing the cutting edge to become thinner, thereby affecting the toughness and service life of the cutter body itself; 2. A first contact ring is arranged on the outer wall of the first reinforcing rib, the second reinforcing rib, the third reinforcing rib, the fourth reinforcing rib and the fifth reinforcing rib, and a first grinding ring is arranged on one side of the first contact ring.

Through the weight of the rod itself, the rod drives the contact pad to press down. During the downward pressing process of the contact pad, the limiting ribs and the hinge seat are driven to press down as a whole, so that the binding strip and the elastic winding ring are wrapped around the surface of the rod to clamp the rod body. At the same time, due to the fixed position of the limiting ribs on the outer wall of the clamping ring, the user can use the clamping position of the binding strip and the elastic winding ring as a section to cut one side of the hinge seat and the binding strip. During the cutting process, the rod is clamped by the hinge seat and the limiting ribs as a whole on the outer wall of the rod, so that the rod remains fixed during the cutting process to prevent the rod from being cut.

When the cutting disc cuts the rod, the microscopic notch on the cutting edge of the tool is easily expanded due to the long-term contact between the rod body and the cutting plate, which accelerates the wear and damage of the tool. When the tool rotates, the cutting edge contacts and grinds with the inner walls of the first contact ring 10 and the second grinding ring 13, so that the blade is slightly ground when it rotates quickly away from the cutting section of the rod body. Three groups of first contact rings 10 and second grinding rings 13 are arranged on the outer walls of the first reinforcing rib 1, the second reinforcing rib 2, the third reinforcing rib 3, the fourth reinforcing rib 4 and the fifth reinforcing rib 5, so that the blade is slightly ground three times when it rotates out of the cutting section, and at the same time, the inner walls of the first contact ring 10 and the second grinding ring 13 are prevented from contacting and grinding with the blade member for a long time, causing the blade to become thinner, affecting the toughness and service life of the tool body itself. Refer to the instruction manual Figure 1-7Furthermore, the inner walls of the first reinforcing rib 1, the second reinforcing rib 2, the third reinforcing rib 3, the fourth reinforcing rib 4 and the fifth reinforcing rib 5 are fixedly connected with a part connecting plate 16, the inner wall of the part connecting plate 16 is fixedly connected with a clamping ring 17, the outer wall of the clamping ring 17 is fixedly connected with a contact pad 18, the inner wall of the clamping ring 17 is clamped with a limiting rib 19, the number of the limiting ribs 19 is two groups, and the two groups of limiting ribs 19 are axially symmetrical about the vertical center axis of the contact pad 18, one end of the limiting rib 19 is fixedly connected with a hinge seat 20, the outer wall of the hinge seat 20 is fixedly connected with a binding strip 21, the outer wall of the binding strip 21 is wrapped with an elastic wrapping ring 22, by passing one end of the rod through the placement adjustment slot 6 The rod is placed on the top of the contact pad 18, and the weight of the rod itself drives the contact pad 18 to be pressed down. During the downward pressing process of the contact pad 18, the limiting ribs 19 and the hinge seat 20 are driven to be pressed down as a whole, so that the binding strip 21 and the elastic winding ring 22 are wrapped around the surface of the rod to clamp the rod body. At the same time, due to the influence of the fixed position of the limiting rib 19 on the outer wall of the clamping ring 17, the user can use the clamping position of the binding strip 21 and the elastic winding ring 22 as a section to cut one side of the hinge seat 20 and the binding strip 21, so that during the cutting process, the rod is clamped by the hinge seat 20 and the limiting rib 19 as a whole on the outer wall of the rod, so that the rod remains fixed during the cutting process to prevent the rod from being cut.

[0023] Working principle: When cutting small-scale rods, one end of the rod is passed through the placement adjustment slot 6 and placed on the top of the contact pad 18. The weight of the rod itself drives the contact pad 18 to press down. During the downward pressing process of the contact pad 18, the limiting rib 19 and the hinge seat 20 are driven to be pressed down as a whole, so that the binding strip 21 and the elastic winding ring 22 are wrapped around the surface of the rod to clamp the rod body. At the same time, under the influence of the fixed position of the limiting rib 19 on the outer wall of the clamping ring 17, the user can use the clamping position of the binding strip 21 and the elastic winding ring 22 as a section to cut one side of the hinge seat 20 and the binding strip 21, so that during the cutting process, the rod is clamped by the hinge seat 20 and the limiting rib 19 as a whole on the outer wall of the rod, so that the rod remains fixed during the cutting and truncation process, preventing the rod from loosening during the cutting and truncation, causing the rod to be clamped on the first reinforcement rib 1, the second reinforcement rib 2, and the third reinforcement rib The inner parts of the reinforcing rib 3, the fourth reinforcing rib 4 and the fifth reinforcing rib 5 are displaced, which affects the initial value of the cutting and truncation of the rod, and affects the subsequent processing and use of the rod. A first contact ring 10 is arranged on the outer wall of the first reinforcing rib 1, the second reinforcing rib 2, the third reinforcing rib 3, the fourth reinforcing rib 4 and the fifth reinforcing rib 5, and a first grinding ring 11 is arranged on one side of the first contact ring 10. The first contact ring 10 and the first grinding ring 11 are connected by a first connecting strip 12 in the middle, so that the overall orientation angle of the first contact ring 10 and the first grinding ring 11 is fixed, and the first grinding ring 11, the first contact ring 10 and the first connecting strip 12 are connected to each other, and an empty groove is formed after the connection. The debris and cooling liquid generated by the cutting of the rod body are guided and discharged through the empty groove to avoid the debris and cooling liquid sticking to the rod cutting part, which affects the user's wrong judgment on the depth of the rod cutting and truncation, and affects the subsequent processing and use of the rod; Wherein, a second grinding ring 13 and a second contact ring 14 are arranged on the opposite surfaces of the first contact ring 10 and the first grinding ring 11. The second grinding ring 13 and the second contact ring 14 are connected by a second connecting strip 15 to form an empty groove which is the same as the first contact ring 10 and the first grinding ring 11, so as to guide and discharge the debris and cooling liquid generated by the cutting of the rod body. When the cutting disc cuts the rod, the microscopic notch of the tool edge is very easy to expand due to the long-term contact between the rod body and the cutting plate, which accelerates the wear and damage of the tool. When the tool rotates, the cutting edge contacts and grinds with the inner walls of the first contact ring 10 and the second grinding ring 13, so that when the blade is rapidly rotated away from the cutting and truncation of the rod body, Three groups of first contact rings 10 and second grinding rings 13 are arranged on the outer walls of the first reinforcing rib 1, the second reinforcing rib 2, the third reinforcing rib 3, the fourth reinforcing rib 4 and the fifth reinforcing rib 5, so that the blade is subjected to three minor grindings when it is rotated out of the cutting and truncation position. At the same time, the inner walls of the first contact ring 10 and the second grinding ring 13 are prevented from being in contact and grinding with the blade for a long time, causing the blade to become thinner and affecting the toughness and service life of the blade body itself. At the same time, under the fit of the first contact ring 10 and the second grinding ring 13 to the blade body, the debris generated by the cutting and truncation of the rod is guided and separated, so as to avoid the debris from accumulating at the cutting and truncation position of the rod and affecting the grinding efficiency.
