Description

Technical Field

[0001] The utility model relates to the technical field of metal plate processing, in particular to a metal plate die pressing device. Background Art

[0002] Sheet metal processing, also known as sheet metal processing, is a key technology that sheet metal technicians need to master, and is also an important process for the formation of sheet metal products. It covers traditional cutting, blanking, bending and pressing methods and process parameters, as well as various cold stamping die structures and process parameters, various equipment working principles and operation methods, as well as new stamping technologies and processes.

[0003] Among them, the application number 202321917692.7 discloses "a metal sheet die-casting device", including a processing table, the bottom ends of the two side walls of the processing table are welded with stabilizing plates, and the upper surface of the stabilizing plate is connected with two stabilizing bolts along the central symmetrical thread. In the above scheme, the die-casting device is provided with an automatic collection component and a collection box. When the metal sheet is die-cast, the hydraulic rod inside the automatic collection component is started, and then the hydraulic rod will drive the push plate to move until the die-cast metal sheet is pushed into the collection box for centralized collection. Because the lower surface of the push plate is in contact with the upper surface of the processing plate, and the length of the push plate is greater than the length of the processing plate, the completeness of the collection can be guaranteed. Because the hydraulic rod has the function of automatic extension and retraction, it can collect the die-cast metal sheet instead of the staff, thereby avoiding contact between the automatic die-casting component and the staff, so that there is no safety hazard in the equipment.

[0004] However, when the above device is in use, during the process of pushing the die-stamped metal sheet to the collection box through the hydraulic rod driving the pushing plate, since the pushing plate pushes the edge of the metal sheet, the pushing plate is prone to curling and deformation due to the force on the edge of the metal sheet during the process of pushing the metal sheet, thereby affecting the product quality of the die-stamped metal sheet. Utility Model Content

[0005] The purpose of the utility model is to provide a metal sheet die-casting device to solve the problem raised in the above-mentioned background technology that in the process of pushing the metal sheet after die-casting to the collection box by driving the pushing plate with a hydraulic rod, since the pushing plate is the edge of the metal sheet being pushed, the pushing plate is prone to curling and deformation due to the force on the edge of the metal sheet during the process of pushing the metal sheet, thereby affecting the product quality problem after the metal sheet is die-cast.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: comprising an equipment body, an electric telescopic rod is fixedly installed on the front side of the upper end of the equipment body, a protective door is fixedly installed on the telescopic part of the lower top of the electric telescopic rod, and auxiliary limit sliding rods are penetrated and movably connected on both sides of the protective door, a main hydraulic rod is fixedly installed on the middle part of the upper top of the equipment body, a pressing plate for pressing metal plates is fixedly installed on the telescopic part of the lower bottom of the main hydraulic rod, and the four corners of the pressing plate are penetrated and movably connected with the main limit sliding rod, a placement groove is opened in the middle part of the upper end of the equipment body, and a processing plate for placing metal plates is rotatably connected to the inner side wall of the placement groove through a pin shaft, and an auxiliary hydraulic rod is rotatably connected to the middle part of the lower end of the equipment body through a pin shaft;

[0007] A limiting straight slide groove is fixedly installed on the outer wall of the lower end of the equipment body, and an L-shaped limiting plate is movably connected to the inner wall of the limiting straight slide groove. An L-shaped supporting plate is fixedly installed on the lower end of the limiting straight slide groove, and a supporting screw is threadedly connected to the middle part of the lower end of the L-shaped support plate. An extension plate is fixedly installed on the upper end of the L-shaped limiting plate, and a feeding slide groove is fixedly installed on the upper support of the extension plate.

[0008] Preferably, there are two auxiliary limit sliding rods, which are symmetrically distributed on both sides of the protective door.

[0009] Preferably, the upper and lower ends of the auxiliary limit sliding rod are fixedly installed at both ends of the front side of the upper end of the equipment body.

[0010] Preferably, there are four main limit sliding bars, which are symmetrically distributed at the four corners of the pressing plate, and the upper and lower ends of the main limit sliding bars are fixedly installed at the four corners of the upper end of the equipment body.

[0011] Preferably, the telescopic portion at the top end of the auxiliary hydraulic rod is rotatably connected to the middle portion of the lower end surface of the processing plate via a pin.
