Description

Technical Field

[0001] This utility model relates to the field of punching equipment technology, and in particular to a riveting punching machine. Background Technology

[0002] Riveting punches, as a type of equipment widely used in the sheet metal processing field, are mainly used to press rivet nuts into pre-drilled holes in sheet metal workpieces to achieve high-strength, high-reliability connections, or to solve the defect of difficulty in drilling threaded holes on sheet metal.

[0003] However, existing riveting punching processes have significant technical bottlenecks. Traditional processes typically require manual placement of the riveting nut into a pre-drilled hole on the stamping table or sheet metal part. Specifically, the operator must manually pick up the nut, precisely position it in the workpiece hole, and then start the stamping program to complete the riveting. This method has the following drawbacks:

[0004] 1. Low efficiency: Manually placing nuts is time-consuming, especially in mass production, where frequent picking and placing actions severely slow down the overall production cycle.

[0005] 2. Positioning accuracy depends on human experience: The operator needs to repeatedly adjust the position of the nut to avoid displacement, but human error can still easily lead to riveting misalignment, resulting in scrapped workpieces or insufficient connection strength;

[0006] 3. Safety hazards: Manual intervention in the stamping area may cause pinching injuries, which does not meet modern industrial safety standards. Utility Model Content

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments: See below Figures 1-6 .

[0030] A riveting punch press includes a worktable 1 and a conveying unit 2 for conveying riveting nuts 3. A punching head 106 is provided above the worktable 1. The punching head 106 is vertically and vertically positioned above the worktable 1 and is used to punch the riveting nut after it falls into the sheet metal part.

[0031] like Figure 1 and Figure 3 As shown, the conveying unit 2 includes a first guide rail 201 and a second guide rail 202. The second guide rail 202 is horizontally arranged on the surface of the workbench 1 and is fixedly connected to the workbench 1. A plurality of first guide rails 201 are connected to the second guide rail 202. The first guide rail 201 and the second guide rail 202 can be integrally formed. The bottom of the first guide rail 201 and the second guide rail 202 are provided with guide grooves 203 that cooperate with the riveting nuts 3.

[0032] The second guide rail 202 is provided with a conveying groove 204, and the first guide rail 201 is provided with a sliding groove 205. The conveying groove 204 and the sliding groove 205 are respectively connected to the guide sliding groove 203 at the bottom of the guide rail to form an inverted T-shaped groove. One end of the riveting nut is provided with a boss, one end of which is locked in the guide sliding groove 203, and the outer wall of the nut can slide relative to the conveying groove 204 or the sliding groove 205.

[0033] The first guide rail 201 and the second guide rail 202 are arranged in a T-shape and perpendicular to each other. Their joint is connected by a conveying groove 204 and a sliding groove 205, so that the rivet nut in the second guide rail 202 can be pushed into the sliding groove 205 by the drive of the joint.

[0034] The two ends of the second guide rail 202 can be connected to a conveyor. The rivet nut with the boss end is placed on the conveyor and continuously enters the conveying groove 204 of the second guide rail 202 through the transmission of the conveyor. It is further conveyed to the connection with the first guide rail 201 by the contact and compression between adjacent rivet nuts.

[0035] As another implementation, the bottom of the guide groove 203 on the second guide rail 202 can also be driven by a chain roller or other means to make the rivet nut placed on the second guide rail 202 slide and be transported.

[0036] The workbench 1 is equipped with a pressing table 102 that is connected to the first guide rail 201. The rear end of the workbench 1 is equipped with a drive push rod 101 that cooperates with the first guide rail 201. Specifically, the drive push rod 101 includes a push rod seat and a telescopic rod 103. The second guide rail 202 is provided with an opening 207 for the telescopic rod 103 to slide through. The opening 207 corresponds to the vertical direction of the first guide rail 201, that is, the telescopic rod 103 and the first guide rail 201 are on the same straight line.

[0037] Initially, the end of the telescopic rod 103 is located on the side of the conveying groove 204 away from the first guide rail 201, that is, in the opening 207. When the conveying groove 204 of the second guide rail 202 contains the rivet nut 3, the drive push rod 101 is activated. At this time, the telescopic rod 103 can push the rivet nut 3 into the sliding groove 205 of the first guide rail 201 and further push it onto the stamping table 102.

[0038] The stamping table 102 is provided with a mounting groove 4 that is adapted to the riveting nut 3. The mounting groove 4 is an arc groove with one end open, and its opening direction is connected to the guide groove 203 at the end of the first guide rail 201.

[0039] The telescopic rod 103 pushes the rivet nut 3 so that the rivet nut 3 slides into the mounting groove 4; the workbench 1 is provided with a lifting push rod 104 connected to the stamping table 102. The mounting groove 4 is connected to the guide slide 203 and abuts against the wall of the first guide rail 201 after the stamping table 102 rises. That is, when the rivet nut 3 is pushed into the mounting groove 4, the lifting push rod 104 starts to raise the stamping table 102. Then, one end of the opening of the mounting groove 4 abuts against the end wall of the first guide rail 201, thereby limiting the rivet nut 3 in the mounting groove 4.

[0040] The stamping table 102 is provided with a plurality of positioning rods 105 for positioning sheet metal workpieces. After the rivet nut 3 is placed in the mounting groove 4, the sheet metal workpiece is placed on the stamping table 102, and the rivet nut 3 is positioned to correspond with the pre-hole on the sheet metal workpiece. The riveting punch includes a punch head 106, and the punch head 106 is provided with a plurality of punch rods 107 adapted to the number of mounting grooves 103. After the punch is started, the punch head 106 slides down and the upper end of the rivet nut 3 is riveted by the punch rods 107, so that the rivet nut 3 is riveted to the sheet metal workpiece, and the riveting is completed.

[0041] After stamping is completed, the riveted sheet metal workpiece is removed, and the push rod 101 and the lifting push rod 104 are driven to reset, ready for the next riveting stamping.

[0042] The sliding groove 205 is symmetrically provided with limiting pins 206 at one end near the second guide rail 202; the limiting pins 206 are elastic pins, thereby preventing the riveting nut 3 from automatically entering the first guide rail 201 and interfering with normal stamping.

[0043] The drive push rod 101 and the lifting push rod 104 are both connected to the PLC controller of the punch press, and the above-mentioned process is automated through programming.

[0044] Using a riveting punch press as described above:

[0045] S1: The PLC controls the lifting push rod 104 to descend, so that the stamping table 102 is reset to the low position;

[0046] S2: The external feeding device continuously feeds the rivet nut 3 into the conveying groove 204 of the second guide rail 202 through the docking with the conveying groove 204 and the guide slide 203 of the second guide rail 202.

[0047] S3: Drive push rod 101 pushes rivet nut 3 to move along sliding groove 205 and overcomes the limit pin 206 limit, then pushes rivet nut 3 into placement groove 4;

[0048] S4: The lifting push rod 104 drives the stamping table 102 to rise, so that the opening end of the mounting groove 4 abuts against the end wall of the first guide rail 201.

[0049] S5: Place the sheet metal workpiece on the stamping table 102 and align the riveting nut 3 with the pre-hole of the sheet metal workpiece. The stamping head 106 presses down to complete the riveting, and each mechanism resets to enter the next cycle.
