Description

Technical Field

[0001] This utility model belongs to the technical field of bolt cold heading processing transfer device, and particularly relates to an automated transfer device for large-size bolt cold heading processing. Background Technology

[0002] Cold heading is a novel metal forming process that involves minimal cutting. It utilizes the plastic deformation of metal under external force, and with the aid of a die, redistributes and transfers the metal volume to form the desired part or blank. Cold heading is best suited for producing standard fasteners such as bolts, screws, nuts, rivets, and pins.

[0003] Currently, small bolts after cold heading are stacked in material boxes for transfer. The subsequent thread rolling process can be carried out using a vibratory feeder. However, if large bolts such as M42 are stacked together, it is not convenient to carry them for subsequent thread rolling. Utility Model Content

[0004] The purpose of this utility model is to provide an automated transfer device for cold heading of large-size bolts in order to solve the above-mentioned problems.

A second screw head limiting groove is provided at the upper end of the second guide groove in an inclined arrangement.

[0011] A guide hopper is fixedly connected to the support frame and extends to the top of the box body. A guide groove is provided at the lower end of the guide hopper, and the guide groove engages with the second screw head limiting groove.

[0012] Multiple limiting rods are inserted into the discharge port of the box body, and the multiple limiting rods abut against the end of the support block.

[0013] As a further description of the above technical solution:

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0034] Please see Figure 1-6 This utility model provides a technical solution: an automated transfer device for cold heading of large-size bolts, comprising:

[0035] Box 1;

[0036] Liquid collection plate 2 is fixedly connected to the bottom of the box body 1;

[0037] Support block 3 is fixedly connected to the liquid accumulation plate 2. The top of the support block 3 is provided with a plurality of first guide grooves 4. The upper end of the first guide groove 4 is provided with a first screw head limiting groove 5 arranged at an inclination.

[0038] The support frame 6 is fixedly connected to the bottom of the housing 1 via a servo slewing bearing 7;

[0039] A guide plate 8 is fixedly connected to the support frame 6. A second guide groove 9 is provided on the guide plate 8. The second guide groove 9 is connected to any of the first guide grooves 4. A second screw head limiting groove 10 is provided at the upper end of the second guide groove 9 in an inclined arrangement.

[0040] A guide hopper 11 is fixedly connected to the support frame 6 and extends to the top of the box body 1. A guide groove 12 is provided at the lower end of the guide hopper 11, and the guide groove 12 is connected to the second screw head limiting groove 10.

[0041] Multiple limiting rods 13 are inserted into the discharge port 14 of the box body 1, and the multiple limiting rods 13 abut against the end of the support block 3;

[0042] The liquid collection plate 2 has multiple liquid collection grooves 15, which correspond one-to-one with the first guide groove 4. The liquid collection grooves 15 are used to collect coolant or lubricant dripping from the screw to prevent it from dripping into the surrounding environment.

[0043] The liquid collection tank 15 is provided with a drain port 16, and a plug 17 is screwed into the drain port 16. By unscrewing the plug 17, the waste liquid in the liquid collection tank 15 can be discharged and cleaned in a concentrated manner.

[0044] The housing 1 has multiple insertion holes 18, and the limiting rod 13 passes through the insertion holes 18 to facilitate the installation and removal of the limiting rod 13.

[0045] The width of the first guide groove 4 is the same as the width of the second guide groove 9, and the width of the first screw head limiting groove 5 is the same as the width of the second screw head limiting groove 10, to ensure smooth bolt sliding;

[0046] The end of the support block 3 is provided with an arc-shaped groove 19, and the end of the guide plate 8 is provided with an arc-shaped surface 20. The arc-shaped surface 20 is tangent to the arc-shaped groove 19, ensuring good connection between the guide plate 8 and the support block 3, thereby ensuring that the bolt can slide smoothly from the first guide groove 4 into the second guide groove 9, and ensuring smooth bolt sliding.

[0047] Working principle: First, large-diameter bolts after cold heading fall into the guide hopper 11. The bolts then fall into the guide groove 12. When the bolts fall from the guide groove 12 into the second screw head limiting groove 10, the bolt head gets stuck in the second screw head limiting groove 10. Due to the unstable center of gravity of the bolt, the main body of the bolt enters the second guide sliding groove 9. Because the second screw head limiting groove 10 is in an inclined state, the bolt slides downwards along the second screw head limiting groove 10. The bolt head enters the first screw head limiting groove 5, and the main body of the bolt enters the first guide sliding groove 4. Because the first screw head limiting groove 5 is in an inclined state, the bolt slides along the first screw head limiting groove 5 until it is stopped by the limiting rod 13. This operation is repeated until a single first guide sliding groove 4 is filled with bolts. Secondly, because the servo slewing bearing 7 can enter... The servo slewing bearing 7 is controlled by a servo motor, allowing it to rotate at a directional angle. This rotation drives the support frame 6, guide hopper 11, and guide plate 8 to rotate as a whole. The arc surface 20 is always tangent to the arc groove 19. The rotation of the guide plate 8 aligns the second guide groove 9 with another first guide groove 4. This process is repeated until all the first guide grooves 4 are filled with bolts. The entire device can then be transported. During the transport, coolant or lubricant dripping from the bolts enters the collection tank 15 for collection. Then, when the bolts are transported to the feeding guide rail of the thread rolling machine, the limit rod 13 is pulled out from the insertion hole 18, and the bolts slide out of the first guide grooves 4 one after another for unloading. Finally, the plug 17 is unscrewed, and the waste liquid is discharged from the drain port 16, completing the centralized discharge and cleaning of the waste liquid in the collection tank 15.

[0048] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
