Description

Technical Field

[0001] This utility model relates to the field of press technology, specifically a protective safety press. Background Technology

[0002] A mechanical press is a sophisticated and versatile machine. It is characterized by its wide range of applications and high production efficiency. Presses are widely used in processes such as cutting, punching, blanking, bending, riveting, and forming. They process metal parts by applying strong pressure to metal blanks, causing plastic deformation and fracture. During operation, a mechanical press is driven by an electric motor via a V-belt to a large pulley (often also serving as a flywheel). This pulley, through a gear pair and clutch, drives a crank-slider mechanism, causing the slide and punch to move linearly downwards. After the forging process is completed, the slide moves upwards, the clutch automatically disengages, and simultaneously, an automatic mechanism on the crankshaft engages, stopping the slide near the top dead center.

[0003] However, existing presses have the following problems during workpiece processing: for some open-type presses, there is a risk of workpieces or component parts spitting out during the extrusion process, posing a safety hazard, and there is a lack of means to protect the working area. Therefore, it is necessary to design corresponding technical solutions to address these technical problems. Utility Model Content

[0004] The purpose of this utility model is to provide a protective safety press, which solves the technical problem that some open presses pose a safety hazard due to the risk of workpieces or component parts breaking off during the extrusion process, and lack of means to protect the working area.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a protective safety press, comprising a press body and two sets of floating protective components symmetrically installed on both sides of the press body. The press body includes a frame with a working chamber in the middle and a hydraulic cylinder installed on the top of the frame. A push rod is installed at the power output end of the hydraulic cylinder, and a pressing block is connected to the bottom of the push rod. The pressing block is movably disposed within the working chamber. A worktable is installed at the bottom of the working chamber. Floating grooves are longitudinally opened on both sides of the frame. The floating protective components... Two sets of connecting rods are symmetrically installed at the front and rear of the frame. Two sets of connecting rods are also symmetrically fixed on both sides of the extrusion block. The outer ends of the connecting rods are connected to the discs. The connecting rods are slidably disposed in the floating groove. The floating protection assembly includes side rods, traction ropes, rollers, and deformation protection plates. The side rods are divided into two sets and are respectively installed on the two sets of discs. One end of the traction rope is connected to the side rod and passes through the roller. The two sets of rollers are installed on the edge of the frame. The lower ends of the two sets of traction ropes are connected to the deformation protection plates, which are installed on the frame.

[0006] In a preferred embodiment of this utility model, two sets of sliding grooves are longitudinally provided on both the front and rear sides of the frame, and sliding rods are provided in the sliding grooves.

[0007] In a preferred embodiment of this utility model, the deformation protection plate includes a bottom plate, a top plate, and a deformation spring plate. The bottom plate is fixed below the frame, and the top plate is located above the top plate and connected to it via the deformation spring plate.

[0008] In a preferred embodiment of this utility model, the top plate is connected to two sets of sliding rods on both sides.

[0009] In a preferred embodiment of this utility model, the deformation plate is made of elastic metal material and has several sets of extrusion grooves formed on its surface, and the surface of the deformation plate has a layered structure.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This utility model improves the existing press structure by equipping floating protective components on both sides of the press. When the press extrusion block moves downward, it can act on the floating protective components, automatically raising them to shield the working area and improve the safety of the press during workpiece processing.

[0012] 2. The press designed in this utility model can achieve the purpose of protecting the working area and improve the safety of the press during use. Attached Figure Description

Detailed Implementation

[0017] 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.

[0018] Please see Figure 1-3 This utility model provides a technical solution: a protective safety press, comprising a press body and two sets of floating protective components symmetrically installed on both sides of the press body. The press body includes a frame 2 with a working chamber 1 in the middle and a hydraulic cylinder 3 installed on the top of the frame 2. A push rod 4 is installed at the power output end of the hydraulic cylinder 3, and a pressing block 5 is connected to the bottom of the push rod 4. The pressing block 5 is movably disposed in the working chamber 1. A worktable 6 is installed at the bottom of the working chamber 1. Floating grooves 7 are longitudinally opened on both sides of the frame 2. The floating protective components are divided into two sets and symmetrically installed on both sides. Two sets of connecting rods 8 are symmetrically fixed on both sides of the extrusion block 5 at the front and rear of the frame 2. The outer ends of the connecting rods 8 are connected to the discs 9. The connecting rods 8 are slidably set in the floating groove 7. The floating protection assembly includes side rods 10, traction ropes 11, rollers 12 and deformation protection plates 13. The side rods 10 are divided into two sets and are respectively installed on the two sets of discs 9. One end of the traction rope 11 is connected to the side rod 10 and passes through the roller 12. The two sets of rollers 12 are installed on the edge of the frame 2. The lower ends of the two sets of traction ropes 11 are connected to the deformation protection plates 13. The deformation protection plates 13 are installed on the frame 2.

[0019] Further improvements, such as Figure 1 As shown, two sets of slide grooves 14 are longitudinally opened at the front and rear of the frame 2, and slide rods 15 are installed in the slide grooves 14.

[0020] Further improvements, such as Figure 1 As shown, the deformation protection plate 13 includes a bottom plate 16, a top plate 17 and a deformation spring plate 18. The bottom plate 16 is fixed below the frame 2, and the top plate 17 is located above the top plate 17 and connected to it through the deformation spring plate 18. The deformation protection plate 13 is used to shield and protect the front and rear of the frame 2.

[0021] Further improvements, such as Figure 1 As shown, the top plate 17 is connected to two sets of slide rods 15 on both sides, and the top plate 17 is adjusted longitudinally along the slide groove 14.

[0022] Specifically, the deformation plate 18 is made of elastic metal material and has several sets of extrusion grooves 19 formed on its surface. The surface of the deformation plate 18 has a layered structure. This design makes it easy to adjust the deformation plate 18 in a telescopic manner, thereby achieving the purpose of protection.

[0023] In use: When the workpiece needs to be extruded, the operator places the workpiece on the workbench 6 and pushes the push rod 4 through the hydraulic cylinder 3 to move the extrusion block 5 downward. At the same time as the extrusion block 5 moves downward, the disc 9 moves downward in sync. The downward movement of the disc 9 moves the traction rope 11, which pulls the top plate 17 upward, thereby extending and opening the deformation spring 18 to protect the front and rear of the workbench 6. When the extrusion block 5 moves upward, the deformation protection plate 13 is reset.
