Description

Technical Field

[0001] The utility model relates to the field of fastener manufacturing and processing, in particular to a splash-proof material guiding groove for a cold heading machine. Background Technique

[0002] The cold heading machine processes steel wires into bolt blanks. The blanks fall from the cold heading machine onto the conveyor belt, and the conveyor belt transports the blanks into the collection box. Generally, a material guiding groove is provided at the discharge port of the conveyor belt to prevent the blanks from falling outside the collection box. However, when the bolts fall on the material guiding groove, they will bounce back and pop out of the material guiding groove, falling outside the collection box, thus affecting the transportation and processing. Content of the Utility Model

[0003] The purpose of the utility model is to provide a splash-proof material guiding groove for a cold heading machine, which has the advantage of preventing the bolt blanks falling into the material guiding groove from splashing out.

[0004] The above technical purpose of the utility model is achieved through the following technical solutions:

[0005] A splash-proof material guiding groove for a cold heading machine includes a cold heading machine, a conveyor belt, a material guiding groove and a collection box. The conveyor belt is close to the discharge port of the cold heading machine. The material guiding groove is connected to the discharge end of the conveyor belt, and the collection box is located below the material guiding groove. Baffles are respectively hinged on both sides of the material guiding groove. A connecting piece is fixedly connected to one end of the baffle hinged to the material guiding groove. Rotating rods are hinged on both sides of the material guiding groove. The two rotating rods are respectively located below the corresponding baffles. A first connecting rod is hinged between the rotating rod on the same side and the connecting piece. A transmission mechanism is connected between the two rotating rods, and the transmission mechanism is connected to the bottom of the material guiding groove.

[0006] By adopting the above technical solutions, after the steel wire is processed into bolt blanks by the cold heading machine, it falls onto the conveyor belt. The blanks are transported by the conveyor belt and fall into the material guiding groove. When the blanks bounce up, they will be blocked by the baffles on both sides of the material guiding groove and will not pop out of the material guiding groove. At the same time, according to the different bouncing heights of bolt blanks with different masses, the transmission mechanism can be adjusted to make the rotating rods on both sides of the material guiding groove rotate. The rotation of the rotating rods drives the connecting piece to rotate through the first connecting rod, thereby driving the baffles on both sides to rotate and adjusting the inclination angle of the baffles to block bolt blanks with different bouncing heights, reducing the impact on processing and transportation.

[0007] Preferably, the transmission mechanism includes a bidirectional lead screw and a second connecting rod. The bidirectional lead screw is rotatably connected to the bottom of the material guiding groove. There are two second connecting rods, which are respectively hinged to the rotating rods on both sides of the material guiding groove. The other ends of the two second connecting rods are respectively hinged to the two sliders of the bidirectional lead screw.

[0008] With the above technical solution, the bidirectional lead screw is rotated, and its two sliders move away from and close to each other. The two moving sliders respectively drive the rotating rods on both sides of the material guiding groove to rotate through the second connecting rod, and the rotating directions of the two rotating rods are opposite, thereby driving the two baffles to rotate and changing their inclination angles.

[0009] Preferably, both sides of the material guiding groove are respectively hinged to both sides of the conveyor belt. A cylinder is hinged to the side of the conveyor belt, and the output shaft of the cylinder is hinged to the side of the material guiding groove.

[0010] With the above technical solution, the cylinder pushes the material guiding groove to rotate, changing the inclination angle of the material guiding groove. The blank falls at different positions in the collection box along the material guiding groove, preventing the blank from accumulating in one place of the collection box.

[0011] Preferably, terminals are fixedly connected to the ends of the bidirectional lead screw.

[0012] With the above technical solution, it is convenient to rotate the bidirectional lead screw.

[0013] Preferably, the collection box is cylindrical.

[0014] With the above technical solution, the volume of the collection box is increased. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The following is only the preferred embodiment of the present invention, and the protection scope is not limited to this embodiment. All technical solutions falling within the idea of the present invention should belong to the protection scope of the present invention. At the same time, it should be pointed out that for those of ordinary skill in the art, several improvements and refinements made without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.

[0019] Refer to Figure 1 - Figure 2, A splash-proof material guiding groove for a cold heading machine, comprising a cold heading machine 1, a conveyor belt 2, a material guiding groove 3 and a collection box 4. The conveyor belt 2 is near the discharge port of the cold heading machine 1. The material guiding groove 3 is hinged at the discharge end of the conveyor belt 2. A cylinder 11 is hinged to the side of the conveyor belt 2, and the output shaft of the cylinder 11 is hinged to the side of the material guiding groove 3. The collection box 4 is located below the material guiding groove 3. Baffles 5 are respectively hinged to both sides of the material guiding groove 3. A connecting piece 6 is fixedly connected to one end of the baffle 5 hinged to the material guiding groove 3. Rotating rods 7 are hinged to both sides of the material guiding groove 3. The two rotating rods 7 are respectively located below the corresponding baffles 5. A first connecting rod 8 is hinged between the rotating rod 7 on the same side and the connecting piece 6. A horizontal bidirectional lead screw 9 is rotatably connected to the bottom of the material guiding groove 3. Two sliders of the bidirectional lead screw 9 are respectively hinged to a second connecting rod 10. The other ends of the two second connecting rods 10 are respectively hinged to the rotating rods 7 on both sides of the material guiding groove 3. A transmission mechanism is connected between the two rotating rods 7, and the transmission mechanism is connected to the bottom of the material guiding groove 3.

[0020] Working principle: According to the size of the bolt to be manufactured, rotate the bidirectional lead screw 9, and its two sliders move away from and close to each other. The two moving sliders respectively drive the rotating rods 7 on both sides of the material guiding groove 3 to rotate through the second connecting rods 10, and the rotating directions of the two rotating rods 7 are opposite. The rotation of the rotating rods 7 drives the connecting piece 6 to rotate through the first connecting rod 8, thereby driving the baffles 5 on both sides to rotate and adjusting the inclination angle of the baffles 5. After the steel wire is processed into bolt blanks by the cold heading machine 1, it falls onto the conveyor belt 2. The blanks are conveyed by the conveyor belt 2 and fall into the material guiding groove 3. When the blanks bounce up, they will be blocked by the baffles 5 on both sides of the material guiding groove 3 and will not pop out of the material guiding groove 3. Then the blanks fall into the collection box 4 along the material guiding groove 3. The cylinder 11 pushes the material guiding groove 3 to rotate, so that the blanks fall at different positions in the collection box 4.
