Description

Technical Field

[0001] This utility model relates to the field of riveting machine technology, specifically a riveting machine with protective function. Background Technology

[0002] Chinese patent application No. 201720680511.1 discloses a riveting machine, including a frame, a conveying structure, and a stamping structure. The upper end of the frame is provided with a hopper, the lower end of the hopper is connected to the conveying structure, the lower end of the conveying structure is connected to the stamping structure, the stamping structure includes a stamping rod, the lower end of the stamping rod is connected to the riveting head through a protective structure, the protective structure includes a protective shell, a threaded sleeve is connected between the protective shell and the stamping rod, a spherical seat is provided inside the protective shell, a main shaft is provided above the spherical seat, and a rotating component is provided inside the spherical seat.

[0003] In the above technical solution, a protective shell is set at the bottom of the stamping rod, so that the protective shell moves synchronously with the punch of the riveting machine. The sloping outer surface of the protective shell prevents the operator from touching the punch of the riveting machine. However, in the above technical solution, when the riveting machine is stamping, the punch exposed on the protective shell still needs to contact the workpiece to be stamped located on the base of the riveting machine. The bottom end of the protective shell, which descends rapidly synchronously with the punch of the riveting machine, still has the possibility of contact with the operator's hand. When operating the riveting machine, the operator's hand is easily pressed into the space formed between the bottom end of the protective shell and the top end of the workpiece to be stamped. Therefore, protection at the end of the punch stroke of the riveting machine is a technical problem that still needs to be solved in the prior art. Utility Model Content

[0004] The purpose of this invention is to provide a riveting machine with protective function that can protect the end of the punch stroke of the riveting machine.

[0005] To achieve the above objectives, this utility model discloses a riveting machine with protective function, including a frame and a base mounted on the frame. One end of the base along its length is located below the riveting machine punch, and the other end of the base is provided with an electric push rod module for feeding rivets along the length of the base to the lower end of the riveting machine punch. The end of the base near the riveting machine punch has a recessed stepped surface as a processing station. A protective mechanism is provided at the upper end of the base near the processing station. The protective mechanism includes a protective ring fixedly mounted on the upper end of the base. The protective ring is located directly below the riveting machine punch and above the processing station. The distance between the bottom surface of the protective ring and the upper surface of the processing station is less than the standard thickness of a human hand.

[0006] During stamping, the electric push rod module feeds the rivet along the length of the base to the processing station located at the lower end of the riveting machine punch. The riveting machine punch passes through the protective ring and descends rapidly, and then stamps through the rivet to fix the workpiece to be stamped. The outer surface of the protective ring prevents the operator from bringing their hands close to the riveting machine punch.

[0007] This invention features a recessed stepped surface at the end of the base near the riveting machine punch, serving as a processing station. A protective ring is installed above this surface. Since the protective ring is located at the end of the punch's stroke, it does not obstruct normal riveting operations and effectively prevents hands from entering the danger zone. This effectively prevents the operator from accidentally placing their hands under the punch during the riveting process. By limiting the distance between the bottom surface of the protective ring and the upper surface of the processing station, it ensures that even if the operator attempts to approach the punch, their hands cannot enter this danger zone. This invention has the advantage of reducing safety risks during operation.

[0008] The electric actuator module has the same structure as existing technologies.

[0009] Preferably, the protection mechanism further includes a Z-shaped support member, which includes a mounting portion fixedly disposed on the upper surface of the base, a support portion that is vertical and disposed at one end of the mounting portion, and a connecting portion disposed at the upper end of the support portion for fixing to the outer circular surface of the protection ring.

[0010] The protective ring is supported by a support member, which limits the distance between the bottom surface of the protective ring and the upper surface of the processing station, while facilitating the installation of the protective ring and thus making it easier to adjust its position.

[0011] Preferably, the lower end face of the protective ring is provided with a base plate that fits the shape of the protective ring. The end of the base plate away from the riveting machine punch is provided with a protective tube and a through hole for communicating with the protective tube. When the riveting machine punch descends, it passes through the center position of the protective ring, the through hole and the protective tube in sequence.

[0012] The protective tube is used to further protect the riveting machine punch and prevent the operator from bringing their hands close to the bottom of the punch during the riveting process.

[0013] Preferably, the inner diameter of the protective tube is smaller than the inner diameter of the protective ring, and the outer diameter of the protective tube is smaller than the outer diameter of the protective ring.

[0014] Compared to extending the height of the lower end of the protective ring until it is close to the workpiece on the processing station, by designing the protective tube to be smaller than the diameter of the protective ring, it can adapt to the riveting machine punch while providing space for the workpiece to be stamped, thus preventing interference between itself and the workpiece to be stamped.

[0015] Preferably, the bottom end of the base plate is provided with a chamfered edge to protect the operator's hands and prevent them from colliding with the protective part when placing the part to be stamped.

[0016] Preferably, the base has a feeding groove arranged along its own length, and the side wall of the feeding groove matches the shape of the power output end of the electric push rod module.

[0017] By using a feeding trough in conjunction with the power output of the electric push rod module for feeding, the stability of the rivet during movement can be ensured, preventing it from tipping over.

[0018] Preferably, the mounting part has an opening, and the mounting part is straddling both sides of the feeding groove in the width direction through the opening, thereby preventing the mounting part from interfering with the rivet.

[0019] Preferably, the mounting part has a mounting groove, and the base has a fixing hole corresponding to the position of the mounting groove. The length of the mounting groove is greater than the inner diameter of the fixing hole, which further facilitates the adjustment of the position of the protective ring and ensures that the protective ring coincides with the axis of the riveting machine punch.

[0020] Preferably, the lower side of the support portion is provided with a relief groove that communicates with the crotch opening, thereby enabling the device to be applicable to rivets of various specifications.

[0021] This invention ensures that even if an operator attempts to approach the punch, their hands cannot enter this dangerous area, thus reducing safety risks during operation. Attached Figure Description
