Description

Technical Field

[0001] The utility model belongs to the technical field of stamping, and particularly relates to a stamping device for sofa connectors. Background Art

[0002] A stamping die generally includes an upper die and a lower die. The upper die is installed on a press, and separation or plastic deformation is generated by applying pressure to obtain the required parts. The stamping die is an important process equipment for realizing sofa connectors (eccentric parts, sofa buckles, inserts, corner connectors, etc.).

[0003] At present, the upper die includes a stripper plate. Through the stripper plate, material can be ejected. Then, through manual material feeding or picking up, the ejected material directly falls on the lower die, resulting in situations of material jamming and deformation problems. Secondly, manual material taking after stamping is unsafe and not conducive to operation efficiency.

[0004] Therefore, in view of the deficiencies of the above solutions in actual production and implementation, they are corrected and improved. At the same time, in the spirit of seeking excellence and with the assistance of professional knowledge and experience, and after various ingenious ideas and tests, the present utility model is created. A stamping device for sofa connectors is provided to solve the above problems. Content of the Utility Model

[0005] The utility model provides a stamping device for sofa connectors, which solves the problems in the prior art.

[0006] The technical solution of the utility model is realized as follows: A stamping device for sofa connectors includes: a lower die and an upper die. A support frame is fitted on the upper die. A linkage rod is fitted on the support frame. One end of the linkage rod is fitted with a transmission mechanism, and the other end is fitted with a receiving box.

[0007] As a preferred embodiment of a stamping device for sofa connectors, a fastening rod fixedly fitted with the upper die is provided at the top of the support frame. A plurality of guide holes are provided on the support frame. A pin shaft is slidably fitted in the guide holes. One end of the pin shaft is provided with an associated rod, and a positioning shaft is provided near the other end. A first connecting member is provided on the associated rod. The linkage rod is fixedly fitted with the first connecting member.

[0008] As a preferred embodiment of a stamping device for sofa connectors, the pin shaft is provided with a jack corresponding to the positioning shaft. The positioning shaft is inserted into the jack, and both ends of the positioning shaft are bent as closing parts.

[0009] By adopting the above scheme, the positioning shaft is used to fix the pin shaft, thereby ensuring the stability of the pin shaft.

[0010] As a preferred embodiment of a stamping device for sofa connectors, the transmission mechanism includes a cylinder. One end of the cylinder is movably engaged with a linkage rod, and the other end is movably engaged with a right-angle frame, which is fixed to the upper die.

[0011] As a preferred embodiment of a stamping device for sofa connectors, one end of the linkage rod is provided with a first shaft body. The cylinder is provided with a shaft frame corresponding to the first shaft body, and the first shaft body is engaged with the shaft frame. The cylinder is provided with a second shaft body corresponding to the right-angle frame, and the second shaft body is engaged with the right-angle frame.

[0012] With the above solution, the telescoping of the cylinder can achieve the movement of the linkage rod, so as to move the receiving box away from or close to the upper die.

[0013] When the receiving box is away from the upper die, the press outputs pressure to deform the sofa part, so as to obtain the required part. When the upper die moves away from the lower die, the movement of the cylinder can make the receiving box close to the upper die. When discharging, the part will fall into the receiving box to complete the recycling, so as to achieve a better working effect.

[0014] As a preferred embodiment of a stamping device for sofa connectors, one end of the receiving box is provided with a second connector, and the linkage rod is fixedly engaged with the second connector.

[0015] After adopting the above technical solution, the beneficial effect of the present utility model is: This device is conducive to better realizing the stamping efficiency. The stamping die includes a lower die and an upper die. The upper die is installed on the press. When the upper die and the lower die are aligned, the sofa part is deformed to obtain the required part. The upper die includes a linkage receiving structure. Before discharging, the linkage receiving structure approaches the upper die, so that the part falls into the receiving box to complete the recycling, achieving a better working effect.
