Technical Field

The utility model relates to a section bar processing equipment field, concretely relates to section bar material feeding unit for section bar processing.

Background

In the building industry and equipment manufacturing industry, section steels with various sections such as angle steel, I-shaped steel, channel steel and the like are widely used as structural members. In the use, need cut and other processings to shaped steel, traditionally, carry out section bar processing production through the manual pay-off cooperation processing equipment of operator. The traditional mode is low in labor productivity and high in worker operation intensity, and the size control precision of manual feeding is influenced by an operator operation method, so that the production quality is difficult to control stably and accurately.

SUMMERY OF THE UTILITY MODEL

In order to solve the productivity ratio low that manual pay-off exists under the prior art, operating strength is big, is difficult to the problem of stable accurate control production quality, the utility model provides a section bar material feeding unit.

The technical scheme of the utility model as follows:

a profile feeding apparatus having a frame, comprising: the feeding seat is provided with a profile clamping mechanism; a moving mechanism, the moving mechanism comprising: the device comprises two linear guide rails arranged in parallel along the length direction of a rack, a rack arranged in parallel with the linear guide rails, a sliding sleeve arranged on a feeding seat and matched with the linear guide rails, a gear arranged on the feeding seat and matched with the rack, and a motor driving the gear, wherein the rack and the gear move in a meshing manner through a helical gear.

Specifically, the helical angle β of the helical gear satisfies:

15°≤β≤25°。

specifically, the section clamping mechanism comprises at least two clamping blocks which are oppositely arranged along the moving direction of the feeding seat, and the clamping blocks are driven by a power device to move in the direction vertical to the moving direction of the feeding seat.

Preferably, a plurality of material supporting devices are arranged on the machine base at the same height with the clamping device at intervals, the material supporting devices are provided with freely rotating idler wheels, and the rotating direction of the idler wheels points to the moving direction of the feeding base.

The utility model provides a section bar material feeding unit has used mechanical pay-off to replace artifical material feeding unit, controls through skewed tooth rack and pinion drive mechanism material feeding unit's feed motion to when realizing reducing mechanical play, improving repeated positioning accuracy, realized weakening equipment and strikeed, reduce the effect of operational noise, optimized the pay-off on section bar processing equipment and fed technology.

Detailed Description

The present invention is described in detail below with reference to the accompanying drawings and specific embodiments, in which the dimensional proportions in the drawings do not represent actual dimensional proportions, but merely represent relative positional relationships and connection relationships between the components, and the components with the same names or the same reference numbers represent similar or identical structures and are only for illustrative purposes.

Fig. 1 is a schematic view of the present invention, two sets of

linear guide rails

12A and 12B are disposed on the upper surface of the frame 1 along the length direction in parallel, and both extend to the two ends of the frame along the length direction of the frame. Between the two linear guides of the machine frame, there are arranged racks 13 parallel to the linear guides and extending also to the two ends of the machine frame, preferably as helical teeth, with a helix angle β of 20 degrees.

The feeding seat 2 is arranged above the rack and is in an inverted U shape, the two protruding portions of the feeding seat are respectively provided with a sliding sleeve set 22A and a sliding sleeve set 22B, the sliding sleeve set 22A is matched with the linear guide rail 12A, and the sliding sleeve set 22B is matched with the linear guide rail 12B, so that the feeding seat 2 can stably move along the linear guide rail. The feeding seat 2 is also provided with a helical gear 21 meshed with the rack on the frame 1, and the gear parameters are the same as those of the rack, so that normal meshing driving is ensured. The helical gear is coaxially connected with a driving motor 24 fixed on the feeding seat, and the helical gear is driven to rotate along the rack in a meshing manner by controlling the motor to rotate, so that the feeding seat is driven to move on the rack along the

linear guide rails

22A and 22B.

A profile clamping mechanism 23 is further arranged above the feeding seat, the profile clamping mechanism is composed of two groups of oppositely arranged clamping blocks 231, the clamping blocks are connected to the end of a telescopic piston rod of a hydraulic cylinder 232, the hydraulic cylinder is fixed on the feeding seat, and the gap and the clamping force between the two oppositely arranged clamping blocks 231 are controlled by controlling the extension and the shortening of a piston rod of the hydraulic cylinder 232.

In the feeding process, one end of the profile to be processed is placed between the two groups of clamping blocks 231, and the control device controls the piston rod of the hydraulic cylinder 232 to extend to push the two clamping blocks to move oppositely, so that one end of the profile to be processed is clamped. And then, the movement of the driving motor is controlled according to external input, so that the position of the feeding seat on the guide rail is accurately controlled.

The utility model discloses in realize right through the meshing cooperation of skewed tooth gear and rack the motion drive and the position accurate control of pay-off seat. The helix angle β of the helical gear in this embodiment should be 15 ° ≦ β ≦ 25 °, and in this embodiment, β is set to 20 °. The helical gear has the advantages that the gear tooth direction is not vertical to the movement direction, the gear teeth which are meshed with each other gradually enter and are disengaged from each other instead of simultaneously entering and disengaging like a common cylindrical gear, so that the helical gear is small in impact and vibration in the operation process, and has the characteristics of small movement noise, stable transmission and high positioning precision. The feeding device is applied to reduce the overall noise of equipment operation and realize accurate and rapid positioning of the sectional material in the length direction.
