Description

A non-fixed-length hydraulic shearing machine

technical field

The utility model belongs to the field of machine tool shearing, in particular to a non-fixed-length hydraulic shearing machine.

Background technique

Second, the non-fixed length produced during the production of bars needs to be manually cut off the line. Due to human factors, dimensional deviation, short-end bending steel, etc., cannot guarantee the success rate, and the existing non-cut lengths are all cut with a fixed-length cutting machine. Only 1-2 pieces can be manually cut each time, and the work efficiency is low. The existing shearing technology covers a large area, has high noise, poor flexibility, high energy and medium consumption during the shearing process, low production efficiency, low length-setting accuracy, and high man-hours.

Utility model content

The technical problem to be solved by the utility model is to provide a non-fixed-length hydraulic shearing machine for manual cutting of short-end bending steel, size deviation and other phenomena.

The utility model is achieved in that a non-fixed-length hydraulic shearing machine comprises:

Rack to support other components;

The feeding part is fixed on the upper end surface of the frame, and a plurality of feeding ports are arranged side by side on it;

When pressing down the steel plate, the contact surface with the steel pipe to be reduced is provided with a plurality of sawtooth corresponding to the feed inlet, which is hydraulically driven by connecting the hydraulic shaft of the pressed steel;

The backing plate is fixed on the frame, and the main shaft is set on it to form a rotating shaft connection with one end of the pressure plate;

The swing arm is an inverted rectangular structure. One end is connected to the shearing hydraulic shaft, and one side is connected to the main shaft on the support plate to form a rotating shaft connection. The shearing hydraulic shaft moves up and down to form a swing around the main shaft. On the contact surface between the swing arm and the steel pipe to be reduced Set up knives.

Further, the cutter is fixed on the swing arm by a hex bolt, and can be replaced as required.

Further, a feeding roller table is arranged on one side of the feeding part corresponding to the inlet position, a receiving roller table is arranged on the other side of the feeding part, and a collection bag is sleeved on the receiving roller table.

Compared with the prior art, the utility model has the beneficial effects that: the utility model optimizes the manpower, and the current number of cutting non-fixed-length personnel is 34, which can be optimized to 16 after the transformation; the accuracy is optimized, and the manual cutting of non-fixed length will be caused by manpower. Due to factors such as size deviation and short-head bending steel, the success rate cannot be guaranteed; efficiency is optimized, and manual operation is transformed into mechanized operation. Now cutting non-fixed lengths are cut by fixed-length cutting machines, and only 1-2 pieces can be manually cut each time. The work efficiency is low, and after the transformation, the online cutting can reach 10-22 according to the specifications each time, and the efficiency is improved.

The factory’s original second bar equipment can be used to modify the out-of-service alignment roller table into a transport roller table, and the discharge port can be equipped with a collection bag. The material of the collection bag needs to be resistant to high temperature and impact, so as to prevent the steel bar from flying out and hurting people.

Detailed ways

In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not intended to limit the utility model.

Embodiment 1 A kind of non-fixed-length hydraulic shearing machine, comprising: frame 9, is used to support other parts; Feed part 8, is fixed on the upper end face of frame 9, and a plurality of feeding ports are arranged side by side on it; Simultaneously enter a plurality of steel pipes, the pressure plate 7, when pressing down, the contact surface of the steel pipe to be reduced is provided with a plurality of sawtooth corresponding to the feed port, which is hydraulically driven by connecting the pressure steel hydraulic shaft 3; when in use, the pressure plate 7 is first lowered Press through the serrations to secure the steel pipe. The backing plate 5 is fixed on the frame 9, on which the main shaft 4 is arranged to form a rotating shaft connection with one end of the pressure plate 7; The main shaft is connected by a rotating shaft, and the shear hydraulic shaft 6 moves up and down to form a swing around the main shaft 4, and a cutter 1 is arranged on the contact surface between the swing arm 2 and the steel pipe to be reduced. The cutter 1 is fixed on the swing arm 2 by a hexagonal bolt, and can be exchanged according to the needs of the shearing force. The shearing hydraulic axis adopts a hydraulic drive pressure of 15Mpa. It can be driven 8 times/min, and the cutting capacity is 100 tons. The stroke of shearing hydraulic cylinder is 270mm;

Example 2

As shown in Figure 2, the difference from Embodiment 1 is that a feeding roller table 11 is set at the corresponding inlet position on one side of the feeding part, and a receiving roller table 10 is arranged on the other side of the feeding part. A collection bag is set on the roller table.
