Description

Technical Field

[0002] The piston pin is a cylindrical pin installed on the piston skirt. Its middle part passes through the small head hole of the connecting rod. It is used to connect the piston and the connecting rod and transmit the gas force borne by the piston to the connecting rod. It is generally made of high-quality alloy steel and made hollow. When actually producing piston pins, a cutting device is required to complete the separation of the alloy steel. During this processing, a feeding device is required to complete the conveying and feeding of the alloy steel. In actual use, it has the advantages of simple operation, stable structure and good use effect.

[0003] The prior art discloses a high-efficiency blanking device for piston pin production with publication number: CN205571111U, comprising a fixing seat, a mounting hole, a cutting die, a feeding hole, an inner cutting knife, a cutting knife, a feeding mechanism, a positioning device, a blade, a raw material, a material section, a base, a side plate, an adjusting screw, a positioning shoe, a bolt, a waist-shaped hole, a first ratchet and a second ratchet. The raw material is placed in the middle of the feeding mechanism, and the two first ratchets and the two second ratchets can clamp the raw material from both sides; then the raw material is transmitted upward by the intermittent rotation of the first ratchet and the second ratchet; during transmission, since the rotation speed of the first ratchet is greater than the rotation speed of the second ratchet, the raw material can be tensioned to improve the straightness of the raw material during transmission. When one end of the raw material is transferred to the positioning device, the top or bottom of the positioning tile can be squeezed or loosened by rotating the adjusting screw, so that the relative distance between the bottom ends of the two positioning tiles is greater than the relative distance between the top ends, and the relative distance between the top ends of the two positioning tiles is equal to the diameter of the raw material, which can guide the raw material, automatically align the raw material with the feeding hole and position the raw material, which is convenient to use and improves the processing efficiency; at the same time, the connection position of the adjusting bolt on the waist-shaped hole can also adjust the relative position between the middle parts of the two positioning tiles to meet the processing of raw materials of different diameters and expand the scope of application. Subsequently, the raw material accurately and straightly passes through the feeding hole into the cutting die, and the side of the raw material is squeezed and cut by the internal cutting knife and the blade. Finally, the fixed length of the raw material extending out of the cutting die is cut off by the reciprocating cutting knife to obtain the processed material section.

[0004] The above utility model requires the use of the first ratchet and the second ratchet to realize the conveying and unloading of alloy steel materials, but there is no gap adjustment structure between the first ratchet and the second ratchet, and the gap length between the first ratchet and the second ratchet is fixed. It can only convey and unload alloy steel materials with the same cross-sectional size, which reduces the practicality of this utility model.

[0035] Working principle:

[0036] When the blanking device for piston pin production is actually used, the operator manually places the alloy steel material inside the groove plate 1, and then inserts one end of the alloy steel material into the installation box 6. Using the two sets of second bearings 11, the operator manually rotates the hand wheel 16, and the hand wheel 16 drives the first two-way screw lever 12 to rotate. Since the first two-way screw lever 12 and the two sets of second screw sleeves 13 threads cooperate with each other, the first two-way screw lever 12 can push the two sets of second screw sleeves 13 to move closer to or away from each other, and the two sets of second screw sleeves 13 respectively drive the two sets of sleeve hole plates 14 to move synchronously. When the two sets of sleeve hole plates 14 are in close contact with the side wall of one end of the alloy steel material, they stop. The hand wheel 16 and the two groups of guide rods 15 ensure the stability of the forward and backward movement of the two groups of socket hole plates 14. The control panel is used to make the first forward and reverse motor 7 work. The output end of the first forward and reverse motor 7 will drive the screw push rod 4 to rotate by using the two groups of first bearings 3. Since the screw push rod 4 and the first screw sleeve 5 threads cooperate with each other, the screw push rod 4 can push the first screw sleeve 5 to move. The first screw sleeve 5 drives the alloy steel material to move horizontally through the I-shaped slider 25 and the installation box 6.

By setting the installation box 6, alloys with various cross-sectional sizes can be The steel material is conveyed and unloaded, which improves the practicality of the unloading device for piston pin production. At the same time, according to the above operation, when the alloy steel material is placed inside the groove plate 1, the control panel is used to make the second forward and reverse motor 24 work, and the output end of the second forward and reverse motor 24 uses four sets of third bearings 19 to drive the second bidirectional wire lever 26 to rotate. Since the second bidirectional wire lever 26 and the two sets of third screw sleeves 20 threads cooperate with each other, the second bidirectional wire lever 26 can push the two sets of third screw sleeves 20 to move closer to or away from each other, and the two sets of third screw sleeves 20 respectively drive the two sets of mounting hole plates 21 to move synchronously, and the two sets of mounting hole plates 21 drives two groups of concave plates 8 to approach or move away from each other through four groups of gantries 22. When multiple groups of groove wheels 10 contact the side wall of the alloy steel material, the first forward and reverse motor 7 is activated.
