Description

Technical Field

[0001] The utility model relates to the technical field of parts processing, in particular to a bolt cold heading processing positioning tool. Background Art

[0002] Bolt cold heading processing is divided into four items: cutting and feeding, extrusion cold heading, material ejection, and position change. In detail, the long material is cut off, the feeding device clamps and sends it to the first cold heading position and aligns it with the mold barrel, then the extrusion mold aligns with the short material and squeezes it into the mold barrel, forming the first cold heading process, then the ejection device ejects the material from the tail end of the mold barrel, the outer feeding device clamps it and moves it to the second cold heading position, and presses it into the second mold barrel through another extrusion die, and so on.

[0003] In the process of implementing this solution, the inventor found that the following problems in the prior art have not been well solved: the mold barrel needs to be customized according to the cold heading size required for the part. If the size is changed, the mold barrel may also be replaced. The mold barrel is generally fixed to the base body by bolts and nuts. During the extrusion cold heading process, a certain degree of collision will occur. The collision can easily cause the nut to be stripped, resulting in a slight loosening of the mold barrel. When the position is cheap, the accuracy of short material insertion will be greatly reduced, which can easily lead to failure of the cold heading process of the material and the material clogging the mold barrel, affecting work efficiency. Utility Model Content

The screws are respectively connected with the ear hole plates that match the position, and the screws are threadedly connected with nuts through the outer wall of one end of the ear hole plate.

[0010] Preferably, the seat mechanism is provided with a traction groove on the side outside the sliding cavity, and a traction block is inserted into the traction groove.

The slider 16 is located at the position of the sliding hole 15 and is fixed with a plug column 17. The barrel 21 is located at the position of the sliding hole 15 and a column groove 22 is bored, and the sliding cavity 14 is located at both ends away from the slider 16. The spring 18 is fixed at both ends.

[0021] Specifically, one end of the insertion column 17 away from the slider 16 is connected to the sliding hole 15, and one end of the insertion column 17 passing through the sliding hole 15 is inserted into the column groove 22 with matching position.

[0022] Specifically, the outer diameter of the plug post 17 matches the inner diameter of the sliding hole 15 and the column groove 22 , respectively, and the inner diameter of the cylinder groove 12 matches the outer diameter of the cylinder body 21 .

[0023] Specifically, the ear hole plate 23 contacts the side wall close to the seat body mechanism 1, and the seat body mechanism 1 is fixed with a screw 3 at the position of the ear hole plate 23. The screw 3 is respectively connected to the ear hole plate 23 with a matching position, and the screw 3 passes through the outer wall of one end of the ear hole plate 23 and is threadedly connected with a nut 4.

[0024] Specifically, the seat body mechanism 1 is provided with a traction groove 112 on the side outside the sliding cavity 14, and a traction block 19 is inserted inside the traction groove 112. The traction block 19 is fixedly connected to the end close to the slider 16, and the end of the traction block 19 away from the slider 16 is fixed with a dial plate 110.

[0027] After the barrel 21 is inserted into the barrel groove 12, its outer side is threadedly connected to the nut 4 through the screw 3 passing through the ear hole plate 23 to reach the original basic limit. The spring 18 pushes the slider 16 to drive the plug 17 from the sliding hole 15 into the barrel groove 12. Since the column groove 22 on the barrel 21 matches the position of the sliding hole 15, the plug 17 can be directly inserted into the column groove 22 from the sliding hole 15, thereby limiting the barrel 21 again. When a collision occurs, the barrel 21 can be stably limited by the insertion of the plug 17, and there will be no displacement, ensuring the stability and success rate of the cold heading process.
