Specific embodiments

[0021] Next, the technical solutions in this embodiment will be clearly and completely described in conjunction with the accompanying drawings in this embodiment. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] As Figure 1 、 Figure 3 shown, this embodiment discloses a rod-shaped raw material cutting device, including a cutting machine 1, a bottom plate 2, and a fixture assembly 3. The bottom plate 2 is provided with a hinged end 21, and the cutting machine 1 is installed at the hinged end 21. The cutting machine 1 includes a blade 12 and a shield 11 covering part of the blade 12. The blade 12 can rotate around the hinged end 21 to approach or move away from the bottom plate 2. The cutting machine 1 is a conventional cutting machine for cutting metals, and the blade 12 is driven by a motor to rotate. The power for the entire cutting machine 1 to rotate around the hinged end 21 can be driven manually by a person or by using hydraulic pressure.

[0023] The bottom plate 2 is provided with a cutting groove 23, and the position of the cutting groove 23 corresponds to that of the blade 12. The cutting groove 23 can accommodate the blade 12. The upper end surface of the bottom plate 2 is provided with a concave surface 22 capable of placing the raw material rod 5. The concave surface 22 extends along the length direction of the bottom plate 2. The middle part of the concave surface 22 is recessed downward to form an arc-shaped groove. The raw material rod 5 is generally a long bar with a circular cross-section. The arc-shaped groove can concentrate the raw material rod 5 in the middle of the concave surface 22, playing a role in positioning the raw material rod 5 to be cut.

[0024] The clamp assembly 3 is installed on both sides of the shield 11. The clamp assembly 3 includes a fixing frame 31, a guide rod 32, a spring 33, a limit block 34, and a pressure head assembly 35. The fixing frame 31 is fixedly installed on the shield 11. The fixing frame 31 extends radially along the rotation direction of the blade 12 around the hinged end 21. The guide rod 32 runs through the fixing frame 31. There are two guide rods 32. The two guide rods 32 make the guidance more stable and prevent the angle deviation of the guide rod 32. The two guide rods 32 are arranged in a radial direction with the hinged end 21 as the center. The guide rods 32 are arc-shaped. The parts of the guide rods 32 passing through the fixing frame 31 also have the same curvature. The arcs formed by the two guide rods 32 are both concentrically arranged with the hinged end 21. The pressure head assembly 35 is installed at the lower end of the guide rod 32. The guide rod 32 is provided with a spring 33. The spring 33 is located between the pressure head assembly 35 and the fixing frame 31. The pressure head assembly 35 rotates around the hinged end 21 to be able to move closer to or farther away. The fixing frame 31 and the spring 33 exert a force on the pressing head assembly 35 to press the raw material rod 5 when the pressing head assembly 35 is close to the fixing frame 31, and also provide a restoring force for the pressing head assembly 35 when it is away from the fixing frame 31. A limit block 34 is installed at the upper end of the guide rod 32, and the limit block 34 limits the maximum distance between the pressing head assembly 35 and the fixing frame 31. When the blade 12 rotates downward around the hinged end 21 and approaches the bottom plate 2, the pressing head assembly 35 also rotates around the hinged end 21 to press against the fixed raw material rod 5. When the pressing head assembly 35 is in an initial state, the initial state is a state in which the blade is lifted and the cutting has not started. The lowermost end of the pressing head assembly 35 is lower than the lowermost end of the blade 12. The pressing head assembly 35 needs to contact the raw material rod 5 before the blade 12, so that before the blade 12 contacts the raw material rod 5, the pressing head assembly 35 has fixed the raw material rod 5, and the clamp assembly 3 can press the raw material rod 5 during cutting. After the cutting machine 1 is lifted, the raw material rod 5 is released, making the cutting work more stable and convenient.

[0025] The pressing head assembly 35 includes a plate 351, which is fixedly connected to the guide rod 32. The first pressing block 352 and the second pressing block 353 are installed on the lower end surface of the plate 351. The first pressing block 352 and the second pressing block 353 are spaced apart along the length direction of the plate 351. The first pressing block 352 is hinged to the lower end surface of the plate 351. The first pressing block 352 can be rotated to facilitate sticking to the outer wall of the pressed raw material rod 5. The first pressing block 352 and the second pressing block 353 are in an eight-shaped shape when pressing the raw material rod 5, which can not only apply pressure to the top of the raw material rod 5, but also clamp the raw material rod 5 from both sides, so that the pressing head assembly 35 can press the raw material rod 5 more stably.

[0026] like Figure 2As shown, the plate 351 is provided with a guide groove 3511, the plate 351 is installed with a screw rod 354, the screw rod 354 passes through the guide groove 3511, a guide block 3531 is installed in the guide groove 3511, the guide block 3531 is threadedly connected to the screw rod 354, and the second pressure block 353 is installed on the lower end surface of the guide block 3531. The rotation of the screw rod 354 can drive the second pressure block 353 to approach or move away from the first pressure block 352. The second pressure block 353 can move to adjust the distance between it and the first pressure block 352, and can be adjusted according to the thickness of the cut raw material rod 5, which is suitable for pressing raw material rods 5 of different diameters.

[0027] More preferably, a pressure pad 355 is installed at the lower end of the first pressure block 352 and the second pressure block 353. The lower end surface of the pressure pad 355 is an arc surface. The pressure pad 355 is made of rubber to increase the friction force with the contact surface with the raw material rod 5. The arc surface of the pressure pad 355 can better produce pressure deformation and fit the outer wall of the raw material rod 5.

[0028] like Figure 3 , Figure 4 As shown, this embodiment also includes a limit plate 4, which is installed on one side of the base plate 2 close to the hinge end 21, and the limit plate 4 includes a plate frame 41 and a limit assembly 42. The plate frame 41 is installed on the base plate 2 through a connecting rod 43, and the connecting rod 43 can be telescopically adjusted. The distance between the plate frame 41 and the base plate 2 controls the length of the cut portion 51 of the raw material rod 5. The plate frame 41 is provided with a through slot 411, and the through slot 411 is connected to the lower end surface of the plate frame 41. The size of the through slot 411 can accommodate the raw material rod 5. The limit assembly 42 is installed at the upper end of the through slot 411, and the limit assembly 42 includes a cylinder 421 and a baffle 422. The baffle 422 is located at the lower end of the cylinder 421. When the cylinder 421 pushes the baffle 422 to extend, the baffle 422 can resist the end of the raw material rod 5, and each time the raw material rod 5 is fed, the baffle 422 will extend to block and limit the raw material rod 5.

[0029] When the raw material rod 5 is cut, the cylinder 421 rises to make the baffle 422 leave the end of the cutting part 51, the pressure head assembly 35, and the bottom plate 2 are provided with a slope 24, and the slope 24 is located at the upper end surface edge of the bottom plate 2 facing the limit plate 4. The cutter 1 rises to make the pressure head assembly 35 leave the raw material rod 5 and the cutting part 51. Since most of the cutting part 51 extends out of the range of the bottom plate 2, the part of the cutting part 51 extending out of the bottom plate 2 will fall downward without the obstruction of the baffle 422. The slope 24 of the bottom plate 2 can reduce the contact area between the cutting part 51 and the bottom plate 2, and guide the cutting part 51 to slide down for automatic unloading.

[0030] The above are only the preferred embodiments of the present utility model, and the protection scope of the present utility model is not limited to the above embodiments. All technical solutions falling within the concept of the present utility model belong to the protection scope of the present utility model. It should be noted that for those of ordinary skill in the art, several improvements and refinements made without departing from the principle of the present utility model should also be regarded as within the protection scope of the present utility model.
