A punch press for easy clamping in chair processing Technical Field
[0001] This utility model relates to the field of chair processing technology, specifically a punch press for chair processing that is easy to clamp. Background Technology
[0002] In the processing of some metal frame chairs, some metal chair shells, such as curved backrest support components, need to be stamped into shape using a punch press. The stamping process usually involves closing two molds and pressing the metal sheet between the two molds into shape. After being formed, the metal sheet is often stuck in the groove of the mold and is not easy to remove. Moreover, incorrect material handling methods may damage or deform the metal sheet. In order to facilitate the insertion and removal of the metal sheet from the groove of the mold and to facilitate the replacement of different molds, this utility model proposes a punch press for chair processing that is easy to clamp.

[0007] Preferably, the lower end of the side plate near the material trough is parallel to the side wall of the material trough, and the upper end is bent away from the material trough.
[0008] Preferably, the bottom of the material groove at the top of the lower mold has multiple through holes, and one end of the bottom of the movable frame extends to the bottom of the mold frame and is fixedly provided with multiple electric push rods, the telescopic ends of the electric push rods can pass through the through holes.
[0009] Preferably, a plurality of studs are fixedly provided on the top of the upper mold, and the movable frame is provided with mounting holes. One end of each stud can pass through the mounting hole and be screwed with a nut for fixing.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting a side plate on the top of the lower mold, the metal plate can be easily guided into the material groove; the mold is clamped and fixed by the fixing bolts of the mounting groove on the mold frame, which facilitates the replacement of different molds; by setting an electric push rod on the moving frame, the length of the electric push rod extension end can be easily adjusted to adapt to the different depths of different material grooves of different molds, so that the extension end of the electric push rod can contact the metal plate in the material groove and push it out of the lower mold while the moving frame is rising, which facilitates the removal of the formed metal plate.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0015] Referring to Figures 1-2, a punch press for chair processing that is easy to clamp includes a mold frame 1. The mold frame 1 has a mounting groove at its top, and a lower mold 2 is installed in the mounting groove. An upper mold 23 is positioned directly above the lower mold 2. A material groove is formed at the top of the lower mold 2, into which the upper mold 23 can enter. The upper mold 23 is fixedly mounted on a movable frame 3. A hydraulic press 31 is mounted at the top of the movable frame 3 and is fixedly mounted on a support frame, with its telescopic end fixedly connected to the movable frame 3. Fixing bolts 11 are screwed onto the side wall of the mounting groove, and an opening is formed at the bottom of the mounting groove. Multiple side plates 21 are provided on the top side of the material groove on the lower mold 2. The lower end of the side plate 21 closest to the material groove is parallel to the side wall of the material groove, while the upper end is bent away from the material groove. The bottom of the material groove at the top of the lower mold 2 has multiple through holes 22. One end of the bottom of the movable frame 3 extends below the mold frame 1 and is fixedly equipped with multiple electric push rods 32. The telescopic ends of the electric push rods 32 can pass through the through holes 22. The top of the upper mold 23 is fixedly equipped with multiple studs 24. The movable frame 3 has mounting holes, and one end of the studs 24 can pass through the mounting holes and be screwed with nuts for fixation.
[0016] When using this device, the metal plate is placed into the material groove of the lower mold 2 along the side wall of the side plate 21. The bottom of the metal plate is supported by the telescopic end of the electric push rod 32. The hydraulic press 31 is started to drive the moving frame 3 to move downward, so that the upper mold 23 moves downward and presses the lower mold 2. The electric push rod 32 moves downward with the moving frame 3, so that the metal plate supported by the electric push rod moves downward and falls to the bottom of the material groove. At this time, the upper mold 23 continues to move downward and extrudes the metal plate in the material groove to form a shape. Then the moving frame is moved upward, and the telescopic end of the electric push rod lifts up the formed metal plate, making it easy for the staff to take it out.
[0017] The orientations or positional relationships shown in the accompanying drawings are for the convenience of describing the present invention and simplifying the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.
