Technical Field

[0001] This utility model relates to the field of cold heading technology for nuts, and in particular to a multi-station cold heading forming equipment for automotive traction nuts. Background Technology

[0002] Cold heading is a processing method that involves upsetting and deforming metal billets at room temperature. By applying strong pressure and a certain speed, the metal billet undergoes plastic deformation, resulting in a forging with the desired shape, size, and mechanical properties. A car tow nut is a specialized accessory used for vehicle towing operations. It is typically installed in specific locations on the vehicle chassis, such as the longitudinal beams, subframe, or axle. It connects to the tow hook of the towing vehicle, enabling towing or movement. During the processing of car tow nuts, cold heading forming equipment is usually used to shape and process them.

[0003] Existing nut cold heading forming equipment can only perform cold heading forming operations on nuts during use, and does not have the ability to quickly unload the nuts after processing. Therefore, we propose a multi-station cold heading forming equipment for automotive traction nuts. Utility Model Content

[0041] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0042] Example:

[0043] like Figures 1-6 As shown, the multi-station cold forging equipment for automotive traction nuts includes:

[0044] Mounting base 1 has symmetrical support columns at its bottom, through holes inside, and a collection box can be placed at its bottom;

[0045] The connecting mounting base 2 is bolted to the top of the mounting base 1, and its top is provided with threaded mounting holes and molding die mounting grooves at equal intervals.

[0046] The forming mold 3 is bolted into the forming mold mounting groove on the top of the connecting mounting base 2;

[0047] Fixed connecting end block 4 is fixedly installed on one side of the top of the forming mold 3;

[0048] Fixed limiting edge block 5 is fixedly installed on the top edge of fixed connecting end block 4;

[0049] The fixed pushing mechanism 6 is bolted to the top of the connecting mounting base 2;

[0050] The material discharge channel 7 is fixedly opened in the middle of the interior of the connecting mounting base 2;

[0051] The fixed pressing and unloading mechanism 8 is fixedly mounted on the top of the connecting mounting base 2.

[0052] The working principle of the above technical solution is as follows:

[0053] During use, the fixed pressing and unloading mechanism 8 cooperates with the forming mold 3 to perform cold heading processing on the nut. After processing, the nut is pushed out by the ejector pin at the bottom of the forming mold 3. Then, the fixed pushing mechanism 6 pushes the nut so that it is at the inner end of the fixed limiting block 5. Then, the internal components of the fixed pressing and unloading mechanism 8 can clamp the nut. The operation is repeated. When the internal components of the fixed pressing and unloading mechanism 8 clamp and fix the next bolt, it will push the previous bolt and guide the bolt to perform the unloading operation, so that the nut can fall into the collection box at the bottom of the mounting base 1 through the discharge channel 7 for collection. The operation is convenient.

[0054] In another embodiment, such as Figure 3 As shown, the fixed pressing and unloading mechanism 8 includes a connecting mounting frame 81. Hydraulic rods 82 are equidistantly arranged on the top of the connecting mounting frame 81. A pressing block 83 is fixedly connected to the output end of the hydraulic rods 82. Electric telescopic rods 84 are equidistantly arranged on the top of the connecting mounting frame 81. A connecting clamping and unloading assembly 85 is fixedly connected to the output end of the electric telescopic rods 84.

[0055] The hydraulic rod 82 and the lower pressure block 83 are designed to cooperate with the forming mold 3, enabling the nut to be cold-forged. Then, under the action of the ejector pin at the bottom of the forming mold 3, the nut can be pushed to the top of the forming mold 3. Next, the fixed pusher mechanism 6 pushes the nut to the inner end of the fixed limit block 5. Then, the electric telescopic rod 84 can push the connecting clamping and unloading assembly 85 downward to clamp and fix the nut, making the operation convenient.

[0056] In another embodiment, such as Figure 4 As shown, the connecting clamping and unloading assembly 85 includes a connecting mounting sleeve 851. Both ends of the connecting mounting sleeve 851 are fixedly connected to the connecting clamping assembly 852. The top inner side of the connecting mounting sleeve 851 is fixedly connected to the fixed extrusion unloading block 853. The bottom of the fixed extrusion unloading block 853 is provided with a first guide slope 854.

[0057] The clamping assembly 852 is designed to clamp and fix the nut. When clamping and fixing the next nut, it will push the previous nut. Under the action of the fixed extrusion block 853 and the first guide slope 854, the nut is extruded and guided, so that the nut can fall into the inside of the discharge channel 7 and fall into the collection box at the bottom of the mounting base 1 for collection. The operation is convenient.

[0058] In another embodiment, such as Figure 5As shown, the connecting clamping assembly 852 includes a connecting sleeve 8521 located on the outer side of the end of the connecting mounting block 851. A force spring 8522 is fixedly connected to the inner side of the connecting sleeve 8521. A connecting mounting plate 8523 is fixedly connected to the other end of the force spring 8522. A fixing connecting rod 8524 is fixedly connected to the side of the connecting mounting plate 8523 away from the force spring 8522. The other end of the fixing connecting rod 8524 passes through the interior of the end of the connecting mounting block 851 and extends to the inner side of the connecting mounting block 851. A connecting clamping arm 8525 is fixedly connected to the other end of the fixing connecting rod 8524. A fixing clamping groove 8526 is provided at one end of the connecting clamping arm 8525. A second guide slope 8527 is provided at the bottom of the inner side of the fixing clamping groove 8526.

[0059] When the second guide slope 8527 is pressed against the edge of the nut, the connecting clamping arm 8525 can move, so that the fixing clamping groove 8526 is fitted onto the outer surface of the nut. When the connecting clamping arm 8525 moves, it can drive the fixing connecting rod 8524 and the connecting mounting plate 8523 to move, which compresses the force spring 8522. At the same time, the force spring 8522 can push the connecting mounting plate 8523, the fixing connecting rod 8524 and the connecting clamping arm 8525 to clamp and fix the nut, making the operation convenient and quick.

[0060] In another embodiment, such as Figure 5 As shown, the connecting clamping arm 8525 is positioned above the ends of the fixed connecting end block 4 and the fixed limiting edge block 5.

[0061] The clamping arm 8525 is designed to be easily connected and can be stably fitted onto the outer surface of the nut when moving downwards, making operation convenient.

[0062] In another embodiment, such as Figure 6 As shown, the fixed pushing mechanism 6 includes a connecting leg 61 that is bolted to the top of the connecting mounting base 2. A connecting sleeve block 62 is fixedly connected to one end of the connecting leg 61. A connecting cylinder 63 is fixedly connected inside the connecting sleeve block 62. A connecting pushing plate 65 is fixedly connected to the output end of the connecting cylinder 63. A fixed positioning guide plate 64 is fixedly connected to the end of the connecting sleeve block 62 near the connecting pushing plate 65. The interior of the fixed positioning guide plate 64 slides against the outer surface of the output end of the connecting cylinder 63.

[0063] The cylinder 63 can push the connecting pusher plate 65 so that the nut can move to the inner end of the fixed limit block 5, making the operation convenient and quick.

[0064] In another embodiment, such as Figure 6As shown, the bottom height of the connecting pusher plate 65 is flush with the top height of the fixed limiting block 5, and the bottom of the connecting pusher plate 65 and the top of the fixed limiting block 5 slide against each other.

[0065] The bottom end of the connecting pusher plate 65 can move on top of the fixed limit block 5 when the connecting pusher plate 65 is moved, so that the nut can be pushed stably and the operation is convenient.

[0066] The working principle of this utility model is as follows: During use, the hydraulic rod 82 pushes the lower pressure block 83 downwards, cooperating with the forming mold 3 to perform cold heading of the nut. After the nut is processed, the nut is pushed by the pin at the bottom of the forming mold 3, causing the nut to detach from the inside of the forming mold 3. Then, the connecting cylinder 63 pushes the connecting push plate 65, allowing the nut to move to the inner end of the fixed limiting block 5. Next, the electric telescopic rod 84 pushes the connecting clamping and unloading assembly 85 downwards, causing the second guide inclined surface 8527 to press against the edge of the nut, which allows the connecting clamping arm 8525 to move, so that the fixed clamping groove 8526 fits onto the outer surface of the nut. When moving, the fixed connecting rod 8524 and the connecting mounting plate 8523 are moved, which compresses the force spring 8522. At the same time, the force spring 8522 pushes the connecting mounting plate 8523, the fixed connecting rod 8524 and the connecting clamping arm 8525 to clamp and fix the nut. When clamping and fixing the next nut, the previous nut is pushed, causing the previous nut to disengage from the inside of the fixed clamping groove 8526 and cooperate with the fixed extrusion unloading block 853 and the first guide inclined surface 854 to extrude and guide the nut, so that the nut can fall into the inside of the discharge channel 7 and be collected by the collection box at the bottom of the mounting base 1. The overall structure is simple and the operation is convenient and quick.

[0067] The above embodiments merely illustrate specific implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
