Description

Technical Field

[0001] This utility model relates to the field of shearing machine feeding reset technology, specifically a shearing machine feeding reset device. Background Technology

[0002] A shearing machine is a machine that uses one blade to reciprocate linearly relative to another blade to shear sheet metal. It utilizes a moving upper blade and a fixed lower blade, with a suitable blade gap, to apply shearing force to metal sheets of various thicknesses, causing the sheet metal to break and separate to the required dimensions. Shearing machines belong to the forging and pressing machinery category and are primarily used in the metal processing industry. Shearing machines are a widely used shearing equipment in machining, capable of cutting steel plates of various thicknesses.

[0003] After feeding, the shearing machine cannot achieve proper reset. To address this, we propose a shearing machine feeding reset device. Utility Model Content

[0004] The purpose of this invention is to provide a feeding reset device for a shearing machine to solve the problems in the prior art.

[0006] Preferably, a sliding sleeve is installed on the lower base at the output rod, and the output rod passes through the sliding sleeve.

[0007] Preferably, the limiting plate and the output rod are locked together by a nut, the top of the guide rod is provided with a limiting protrusion, and the guide rod and the lower base are connected by a thread.

[0008] Preferably, there are 4-6 guide rods in total, and the guide rods are arranged in a ring.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: a sliding sleeve is installed on the lower base at the output rod, and the output rod passes through the sliding sleeve; a limiting plate is installed on the top of the output rod, and multiple guide rods are installed on the lower base, with the guide rods passing through the limiting plate. A return spring is sleeved on the guide rod, and the two ends of the return spring abut against the lower base and the limiting plate respectively; an upper base is installed on the top of the lower base, and a hydraulic cylinder for driving the output rod is installed on the top of the upper base. After the hydraulic cylinder drives the output rod, the hydraulic cylinder returns to its original position, and the return spring drives the limiting plate to move toward the hydraulic cylinder, thereby causing the limiting plate to reset the output rod.

Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.

[0017] Please see Figure 1-4 In this embodiment of the present invention, a shearing machine feeding reset device includes a lower base 4, on which an output rod 3 is slidably mounted. A sliding sleeve 7 is installed on the lower base 4 at the output rod 3, and the output rod 3 passes through the sliding sleeve 7. A limiting plate 5 is installed on the top of the output rod 3. A plurality of guide rods 6 are installed on the lower base 4, and the guide rods 6 pass through the limiting plate 5. A reset spring is sleeved on the guide rod 6, and the two ends of the reset spring abut against the lower base 4 and the limiting plate 5, respectively. An upper base 2 is installed on the top of the lower base 4, and a hydraulic cylinder 1 for driving the output rod 3 is installed on the top of the upper base 2. After the hydraulic cylinder 1 drives the output rod 3, the hydraulic cylinder 1 returns to its original position, and the reset spring drives the limiting plate 5 to move toward the hydraulic cylinder 1, thereby causing the limiting plate 5 to reset the output rod 3.

[0018] The limiting plate 5 and the output rod 3 are locked together by a nut. The top of the guide rod 6 is provided with a limiting protrusion. The guide rod 6 and the lower base 4 are connected by a thread. There are 4-6 guide rods in total. The multiple guide rods 6 are distributed in a ring, which makes the force uniformity better.
