Description

Technical Field

[0001] The utility model belongs to the technical field of shearing machines, and particularly relates to a pressure frame for a shearing machine and a shearing machine. Background Art

[0002] A shearing machine is a mechanical device used to cut metal materials. In the rolling production process, after large-section ingots and billets are rolled, their cross-sections become smaller and their lengths increase. In order to meet the requirements of subsequent processes and product size specifications, a shearing process must be included in various steel production processes.

[0003] When a shearing machine shears cylindrical steel materials, the steel materials are usually fixed, and then the cutting tool is used to shear the steel materials. When multiple shears are required for longer steel materials, the operator needs to use a pressure device to fix the steel materials. The operator performs a series of frequently repeated operations such as fixing, shearing, disassembling, moving the steel materials, and refixing, which seriously affects work efficiency. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide a pressure frame for a shearing machine and a shearing machine. This pressure frame can not only press and fix the steel materials, but also drive the steel materials to move for feeding.

[0005] The purpose of the utility model can be achieved by the following technical solutions:

[0006] The pressure frame for a shearing machine includes:

[0007] A support frame, on both sides above the bottom plate inside the support frame, first sliding rods are fixedly connected. Support blocks are slidably connected to the first sliding rods. One end of the support frame is rotatably connected with a support roller. A first chute is opened on the bottom plate of the support frame. Inside the support frame and below the bottom plate, a lead screw is rotatably connected. A moving plate is threadedly connected to the lead screw. The upper end of the moving plate extends upward through the first chute. A second chute and an adjustment groove communicating with the second chute are opened on the moving plate. An extension plate is slidably connected to the second chute. A bolt passes through the adjustment groove and is threadedly connected to the extension plate;

[0008] A lifting plate, on which a third chute is opened. A second sliding rod is fixedly connected below the lifting plate. A slider is slidably connected to the second sliding rod. The upper end of the slider is slidably connected inside the third chute, and the lower end is fixedly connected with a pressure block. Below one end of the lifting plate, a pressure roller corresponding to the support roller is rotatably connected;

[0009] A lifting rod, the lower end of which is fixedly connected to the support frame, and the output end of which is fixedly connected to the lifting plate.

[0010] The above technical solution, its principle and technical effect:

[0011] Connect one end of the support frame with the support rollers to the shearing equipment for installation. Place both ends of the cylindrical steel material on the support blocks and support rollers. Drive the lifting rod to contract, and the lowering of the lifting plate drives the pressing block and the pressing roller to press the steel material. After the front end of the steel material is sheared, adjust the height of the extension plate, drive the screw rod to rotate, drive the moving plate and the extension plate to push the support block and the pressing block to move, and the support block and the pressing block drive the steel material to move towards the shearing equipment for feeding.

[0012] Further, a first arc-shaped groove is provided on the upper end surface of the support block, and a second arc-shaped groove is provided on the lower end surface of the pressing block.

[0013] Further, the diameters of the support rollers and the pressing rollers gradually decrease from both ends to the middle.

[0020] A shearing machine, including a pressure frame for the shearing machine.

[0021] Regarding the nouns, conjunctions or adjectives involved in the above technical solutions, the explanations are as follows:

[0022] Fixed connection means that after the parts or components are fixed, there is no relative movement connection. It is divided into two types: detachable connection and non-detachable connection.

[0023] (1) Detachable connection uses screws, splines, wedge pins, etc. to fix the parts together. This connection method can be disassembled during maintenance and will not damage the parts. However, the specifications of the connecting parts used must be correct (such as the length of bolts, keys, wedge pins), and they must be tightened properly.

[0024] (2) Non-detachable connections mainly refer to welding, riveting, and mortise fitting, etc. Since they need to be forged, sawed, or oxy-cut to be disassembled during maintenance or replacement, spare parts generally cannot be reused. At the same time, during connection, attention should be paid to process quality, technical inspection, and remedial measures (such as correction, polishing, etc.).

[0025] Threaded connection refers to a detachable connection that connects the connected parts into one body with threaded parts (or the threaded parts of the connected parts).

[0026] Sliding connection means that two objects are in contact but not fixed, and they can slide relative to each other.

[0027] Rotational connection means that the connection between parts allows the parts to rotate relative to each other.

[0028] Advantages of the present utility model:

[0029] This pressure material holder can not only press and fix the steel material, but also drive the steel material to move for feeding. Description of the drawings
