Abstract
The invention relates to a method for realizing upper/lower chamfering forming of a pre-stressed anchorage device. The method is characterized by comprising the following steps of: preparing an upper limiting plate and a lower limiting plate, wherein an upper chamfering press head limited by the upper limiting plate is arranged on the upper limiting plate, the end head of the upper chamfering press head is protruded, a lower chamfering press head limited by the lower limiting plate is arranged on the lower limiting plate, and the end head of the lower chamfering press head is protruded; placing the pre-stressed anchorage device between the upper limiting plate and the lower limiting plate, and limiting the upper chamfering press head to be at a position right opposite to an upper hole in the pre-stressed anchorage device; limiting the lower chamfering press head to be at a position right opposite to a lower hole in the pre-stressed anchorage device; and applying force onto the upper limiting plate and the lower limiting plate from the upper surfaces and the lower surfaces of the upper limiting plate and the lower limiting plate. The method for realizing the upper/lower chamfering forming of the pre-stressed anchorage device has the advantages that the conventional machine work manner is replaced by a cold extruding manner to be used for carrying out chamfering processing on the pre-stressed anchorage device, and the processes of upper/lower chamfering and character code pressing of a pre-stressed mold are integrated into one process, so that the labor productivity is improved, the processing cost is lowered, and processed chamfers and character codes are relatively regular, smooth and attractive; and the method is suitable for mass production.
Description
Technical field
The present invention relates to a kind of prestressed anchor be made processing method, particularly relates to a kind of up and down method of chamfering moulding of prestressed anchor that once realizes.
Background technology
The round taper hole ground tackle of porous is to keep prestressed critical piece during the mixed earth of prestressing force makes up.Existing ground tackle taper hole chamfer angle technique is generally and utilizes the drilling machine chamfering, and the drilling machine chamfering generally can only next hole.The manual chamfering of common driller can't guarantee the uniformity of chamfering, and is easily not of uniform size.The mode of existing ground tackle typewriting code generally have beat by hand, the modes such as punch ram and forcing press extruding.Existing ground tackle taper hole chamfering and typewriting code technique have the following disadvantages: 1, chamfering is even not, and is easily not of uniform size; 2, character code is regular not, smooth and attractive in appearance; 3, process efficiency is not high, and cost is high.
Summary of the invention
Purpose of the present invention just provides a kind of cold-stamped mode of utilizing and replaces traditional machining mode that prestressed anchor is carried out chamfer machining, and to the upper and lower chamfering of prestressed anchor with press the operation of character code to be integrated into a procedure, improved labor productivity, reduced processing cost, and make the chamfering and the character code that process more regular, smooth and attractive in appearance, the up and down method of chamfering moulding of prestressed anchor that once realizes that is applicable to produce in enormous quantities.
Solution of the present invention is such:
Method of the present invention comprises step:
(1), preparation upper limit plate and lower limiting board, be provided with by the upper limit plate at the upper limit plate and carry out upper chamfering pressure head spacing, that protrude its termination, be provided with by lower limiting board at lower limiting board and carry out lower chamfering pressure head spacing, that protrude its termination;
(2), prestressed anchor is positioned between upper limit plate and the lower limiting board a upper chamfering spacing position to hole on prestressed anchor; A lower chamfering spacing position to hole under the stress ground tackle;
(3), from upper and lower faces upper limit plate and lower limiting board are exerted pressure, until the chamfer machining moulding.
Further: also comprise step in the described step (1): the character code shaping mould of protrusion is set at upper limit plate or lower limiting board, by one-shot forming character code is beaten on ground tackle.
Advantage of the present invention is to utilize the cold-stamped mode to replace traditional machining mode that prestressed anchor is carried out chamfer machining, and to the upper and lower chamfering of pre-stress die with press the operation of character code to be integrated into a procedure, improved labor productivity, reduced processing cost, and make the chamfering and the character code that process more regular, smooth and attractive in appearance, be applicable to produce in enormous quantities.
Description of drawings
Accompanying drawing is embodiments of the invention.
Accompanying drawing 1 is implementation method schematic diagram of the present invention.
Accompanying drawing 2 is the schematic diagrames that add man-hour with forcing press.
The specific embodiment
As shown in Figure 1, describe with the ground tackle to two holes, its method step is:
(1), preparation upper limit plate 1 and lower limiting board 4, be provided with by the upper limit plate at upper limit plate 1 and carry out upper chamfering pressure head 2 spacing, that protrude its termination, be provided with by lower limiting board at lower limiting board 4 and carry out lower chamfering pressure head 5 spacing, that protrude its termination; Upper chamfering pressure head 2 and lower chamfering pressure head 5 are separately fixed on upper limit plate 1, the lower limiting board 4, over against two holes; At the upper limit plate 1 fixing character code shaping mould 3 that protrudes;
(2), prestressed anchor 6 is positioned between upper limit plate 1 and the lower limiting board 4 upper chamfering 2 a spacing position to hole on prestressed anchor; Lower chamfering 5 a spacing position to hole under the stress ground tackle;
(3) and with whole device put into the parallel forcing press in top and bottom 7, from upper and lower faces upper limit plate 1 and lower limiting board 4 are pushed, until the chamfer machining moulding, but up and down chamfering and the just one-shot forming of ground tackle character code of taper hole.
Claims (2)
1. once realize the up and down method of chamfering moulding of prestressed anchor for one kind, it is characterized in that comprising step:
(1), preparation upper limit plate (1) and lower limiting board (4), be provided with by the upper limit plate at upper limit plate (1) and carry out upper chamfering pressure head (2) spacing, that protrude its termination, be provided with by lower limiting board at lower limiting board (4) and carry out lower chamfering pressure head (5) spacing, that protrude its termination;
(2), prestressed anchor (6) is positioned between upper limit plate (1) and the lower limiting board (4) the spacing position to hole on prestressed anchor of upper chamfering head (2); The spacing position to hole under the stress ground tackle of lower chamfering head (5);
(3), from upper and lower faces upper limit plate (1) and lower limiting board (4) are exerted pressure, until the chamfer machining moulding.
2. once realize the up and down method of chamfering moulding of prestressed anchor for one kind, it is characterized in that also comprising step in the described step (1): the character code shaping mould (3) that protrusion is set at upper limit plate (1) or lower limiting board (4).
