Description

Stripping rib rolling straight thread machine

(1), technical field

The utility model relates to strong stripping rib rolling straight thread machines such as a kind of tensile strength that can realize splice place and parent material of reinforcement rebar.

(2), technical background

Reinforcing bar equal strength straight thread interconnection technique is the most up-to-date techniques of the international mechanical connection technique of reinforcement nineties in 20th century.The tetanic technology that is threaded such as reinforcing bar of the prior art connects for adopting the jumping-up straight thread, because equipment heaviness, each a set of equipment of jumping-up mantle fiber, the site construction inconvenience, and the reinforcing bar after the cold-heading is easy to generate cold broken phenomenon, the quality instability is so generally be used for the II grade reinforcing steel of tensile strength less than 500MPA.In addition, the present main hard nut to crack of straight thread rolling installation is that the knife rest location is inaccurate, and stripping rib length is unsuitable, adopts the rolling mode to be prone to tapered thread, and is short during rolling length duration, and the operative employee is difficult to grasp.

(3), Fa Ming content

Technical problem to be solved in the utility model provides a kind of employing stripping rib rolling straight thread interconnection technique, need only can on-the-spotly process by an equipment, easy operating, can make strength of parent improve 20%, and steady quality is shelled rib rolling straight thread machine reliably, be not only applicable to the II grade reinforcing steel and connect, be equally applicable to the III grade reinforcing steel and connect.

Technical problem to be solved in the utility model is to adopt such technical scheme to realize, it is a kind of stripping rib rolling straight thread machine, it is characterized in that: comprise lathe bed, be fixed on the vice on the lathe bed, preceding block plate, back block plate, and the assembly that constitutes of cutter box, rolled thread parts, main spindle box, decelerator motor by same axis; Wherein, preceding block plate is fixed on the front end of guiding transverse axis, and back block plate, the assembly shell that reaches cutter box, rolled thread parts, main spindle box, decelerator motor formation and guiding transverse axis are slidingly matched; The lathe tool seat and the lathe tool that are supported by the top spring radially are installed in the cutter box, and the lathe tool box has sliding sleeve outward with spring and the radially inwardly extruding of lathe tool seat; The rolled thread parts are positioned at after the lathe tool box, are made of the filament rolling machine that rolls that is positioned at the roller box.

The utility model has been broken through the shortcoming that former rolling type is difficult to overcome because said structure, can accomplish the stripping rib orientate as ± 0.5 millimeter, the rolling positioning accuracy is ± 0.5 millimeter; Be convenient to realize the semi-automation operated alleviated labor strength greatly; And improve work efficiency 20%, guaranteed machining accuracy, make the connection more convenient and quicker, the effect of ensuring the quality of products.

(4), description of drawings

The utility model has following accompanying drawing:

Accompanying drawing 1 is a structural front view of the present utility model;

Accompanying drawing 2 is a structure side view of the present utility model;

Accompanying drawing 3 for the utility model lathe tool box be positioned at before structural representation during block plate 6 positions;

Accompanying drawing 4 is for removing the structural front view of sliding sleeve 15 back lathe tool boxes;

Structural representation when accompanying drawing 5 is positioned at block plate 9 positions, back for rolled thread parts 8

Accompanying drawing 6 is the side view of lathe tool box;

Accompanying drawing 7 is the utility model machining state schematic diagram.

Referring to accompanying drawing: 1-vehicle body, 2 among the figure-operation handwheel, 3-tooth bar, 4-gear, 5-vice, 6-preceding block plate, 7-lathe tool box, 8-rolled thread parts, 9-back block plate, 10-main spindle box, 11-decelerator, 12-motor, 13-slip transverse axis, 14-spring, 15-roll filament rolling machine, 16-sliding sleeve, 17-workpiece.

(5), specific embodiment

Said structure of the present utility model is further specified by the embodiment that accompanying drawing provides.

Referring to accompanying drawing, the stripping rib rolling straight thread machine among the figure comprises lathe bed 1, is fixed on vice 5 on the lathe bed, preceding block plate 6, back block plate 9, and the moving body assembly that constitutes of lathe tool box 7, rolled thread parts 8, main spindle box 10, decelerator 11, motor 12 by same axis; Wherein, preceding block plate 6 is fixed on the front end of guiding transverse axis 13, and the housing of moving body assembly is slidingly matched with the guiding transverse axis; The lathe tool seat and the lathe tool that are supported by top spring 14 radially are installed in the cutter box, have sliding sleeve 16 outside the lathe tool box 7 spring and the radially inwardly extruding of lathe tool seat; Rolled thread parts 8 are positioned at after the lathe tool box, are made of the filament rolling machine 16 that rolls that is positioned at the roller box.

In said structure, the housing bottom of the moving body assembly that lathe tool box 7, rolled thread parts 8, main spindle box 10, decelerator 11, motor 12 constitutes has tooth bar 3, by the gear, the gear shaft that are engaged with and the operation handwheel 2 on being positioned at vehicle body be connected.

The operation principle of the utility model said structure is such:

1, the length of workpiece 17 (screw-thread steel) by sign is clamped on vice 5;

2, turn operation handwheel 2, the tooth bar 3 by the 4 drive moving body bottoms of the gear on the wheel shaft moves forward and backward moving body; During operation, should fall back on the position earlier, even the rolled thread parts are positioned at position as shown in Figure 5;

3, fall back on the position after, stripping rib lathe tool is because the effect of back block plate makes sliding sleeve 16 reaches, and with 14 compressions of the top spring in the lathe tool box, lathe tool is promptly opened, for the stripping rib is got ready, referring to accompanying drawing 4;

4, the turn handwheel moves forward and starts working then, promptly begins to shell rib after stripping rib lathe tool touches workpiece;

5, after continuation stripping rib is advanced to the workpiece preseting length, because the effect of preceding block plate will move behind the sliding sleeve, because the effect of stripping rib lathe tool spring is outwards ejected the lathe tool box, lathe tool promptly opens, as shown in Figure 3;

6, continue turn handwheel forward, enter the squeezing thread stage, as shown in Figure 7, because the effect of screw thread, autofeed forward at this moment.

7, by electrical control to behind the preseting length, motor counter-rotating, the rotation direction of pressing screw thread is released automatically;

8, after falling back on the position, the turn handwheel falls back on original position backward, and rib peeling knife is closed again, prepares for work next time, and takes out workpiece.

Because workpiece produces heat in process, can increase already present cooling body in the prior art in the device.
