Description

Technical Field

[0001] This invention relates to the field of cutting equipment technology, specifically a cutting device for riveting parts processing. Background Technology

[0002] In many fields such as machinery manufacturing, automobile assembly, and electronic equipment assembly, T-shaped rivets are an important connecting component. Due to their stable structure and strong connection, they are widely used in scenarios requiring high-strength fixation. The core of T-shaped rivet processing lies in precisely cutting the columnar rod to form a head structure of a specific shape. In the industry, most processing equipment for T-shaped rivets relies on manual single-pass feeding or simple material trough natural feeding, which cannot achieve automatic single-pass unloading and posture correction of the rod. Furthermore, the rod needs to be vertically clamped on the cutting equipment, and natural feeding makes it difficult to ensure the orderly supply of rods. After cutting, the rivets are mostly dropped naturally. Because the rod is cut while rotating, it is easy to scatter when falling, lacking orderly material collection, which can easily cause workpiece collisions and scratches, affecting the product's appearance and precision.

[0013] The cutting device for riveting parts proposed in this invention has the following advantages:

[0014] 1. Through the coordinated design of the stacking unit and the adjusting baffle, flexible adaptation to rods of different diameters and lengths is achieved. The stacking unit adjusts the distance between the first and second stacking seats by rotating the second screw rod, and with the guidance of the limiting rod, it can accurately match the stacking limit of rods of different diameters. The adjusting baffle of the unloading structure moves by rotating the first screw rod, which can adjust the effective accommodating space in the unloading seat according to the length of the rod, avoiding material jamming or disordered unloading due to differences in rod length. It can meet the processing needs of T-shaped rivet parts of various specifications without changing special tooling fixtures, greatly reducing equipment changeover costs and improving production flexibility.

[0015] 2. Achieve fully automated connection from raw material stacking to finished product collection, reducing manual intervention; adopting gravity stacking and tilting unloading seat design, the rods are automatically arranged and unloaded by their own weight, without the need for additional power to drive the feeding, which is energy-saving and efficient; through the mechanical linkage of unloading seat flipping and pressure claw pressing, the posture transformation from horizontal to vertical of a single rod is automatically completed, without the need for manual adjustment of the rod direction, solving the problem of time-consuming posture correction in traditional processing; the dual electric slide rails and three-jaw clamping unit of the transfer structure achieve precise handling, which works in conjunction with the cutting unit and top-loading unit of the receiving structure to form a closed loop process of unloading, transfer, processing and receiving, greatly increasing the processing volume per unit time and reducing the intensity of manual labor.

[0016] 3. During the unloading stage, the precise positioning of a single rod is achieved through the cooperation of the arc-shaped groove of the pad and the arc-shaped jaw of the pressure claw, avoiding deviation during unloading. After the posture conversion, the rod is in a vertical state, and the three-jaw clamping unit of the transfer structure can stably clamp it from the end. With the first motor driving the rod to rotate, it ensures that the rod speed is uniform and the radial runout is small during cutting. The docking box cut and the top material unit positioning of the receiving structure fix the axial position of the rod during the cutting process. The cutter precisely adjusts the cutting position through the bidirectional slide rail, effectively controlling the head size accuracy of the T-shaped rivet and reducing the defect rate.

[0017] 4. To address the pain point of collecting rivet parts after processing, a dedicated guiding structure was designed to balance safety and convenience, preventing safety hazards caused by workpiece splashing after high-speed cutting. Attached Figure Description

[0043] First, the equipment is placed and supported stably by the base 1. After the equipment is powered on, the cut rods can be placed in the stacking unit 30. According to the diameter of the rods, the second spiral rod 304 is rotated to cause the second stacking seat 303 to be stressed. The distance is adjusted by moving relative to the first stacking seat 301 using the limiting rods 302. Then, the L-shaped first stacking seat 301 and the second stacking seat 303 form a concave shape, thereby blocking the rods and achieving stacking by their own weight.

[0044] The bottommost rod in the stacking unit 30 will enter the unloading seat 23 in the unloading structure 2 and be arranged again in the unloading seat 23. Due to the inclined wall of the unloading seat 23 and the movable setting of one end of the unloading seat 23, the rod is attached to the side wall of the pad 22 on the bearing plate 21, which can activate the electric push rod 27 on the first bracket 20 to retract. By using the two ends of the linkage frame 29 to move in the filling groove 64 of the slide 28, the unloading seat 23 is rotated, causing the end near the pad 22 to be lifted, thereby raising the rod attached to the side wall of the pad 22 and rolling it into the groove 61, realizing the single rod discharge.

[0045] Then the electric push rod 27 extends and drives the unloading seat 23 to flip and reset, thereby driving the pressure claw 26 opposite to the pad 22 to descend, thereby pressing down one end of the rod, causing the rod to flip with the force of the front side of the pad 22, and vertically clamping it between the jaw 63 of the pressure claw 26 and the pad 22.

[0046] This drives the first electric slide rail 41 in the transfer structure 4, which in turn raises the second electric slide rail 43 on the mounting frame 42. The second electric slide rail 43 then moves the corresponding three-jaw clamping unit 45 above the rod, lowers it to clamp and pick up the material, and then moves the rod above the docking box 52 in the receiving structure 5.

[0047] Secondly, the rod is lowered and inserted into the top of the docking box 52 via the first electric slide rail 41. At the same time, the third electric slide rail 561 in the top material unit 56 is activated. With the help of the lifting frame 562, the lifting seat 563 and the tilting table 564 are raised in the docking box 52, and can be supported against the lower wall of the rod.

[0048] The first chassis unit 44 drives the three-jaw clamping unit 45 to rotate, thereby realizing the rotation of the rod. The rotating rod comes into contact with the cutter 574 in the cutting unit 57 and can be processed into a T-shape.

[0049] The cutter 574 is driven to lift and feed via the bidirectional slide rail 571. The second housing unit 572 is activated to rotate the tool holder 573, thereby changing the cutter 574 at both ends of the tool holder 573. The cutter 574 is fed relative to the cutting opening 7. When the cutter 574 contacts the rod, it can perform T-shaped cutting. After the shape is cut, the formed riveted part is cut off by the continuous feeding of the cutter 574.

[0050] After being cut, the riveted part, located in the docking box 52 supported by the riser frame 51, will fall onto the tilting table 564. Then, it will descend to the discharge port 8 via the tilting table 564. At this point, the hydraulic cylinder 565 on the lifting seat 563 can be activated to retract, causing the tilting table 564 to tilt and slide down into the discharge slide 53. The riveted part will be intercepted by the intercepting net 54 at the other end of the discharge slide 53, and the debris will be filtered into the collection box 55 for recycling. Alternatively, the intercepting net 54 can be removed, and the riveted part can be directly placed into the collection box 55 for storage.

[0051] Because of the different lengths of the rods, the first spiral rod 24 located in the moving groove 62 can be rotated to drive the adjusting baffle 25 to move, thereby adjusting the distance between the adjusting baffle 25 and the pressure claw 26, and driving one of the stacking units 30 to move, so as to realize the use of rods of different lengths for limiting.

[0052] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
