Embodiment 1

[0073] Such as figure 1 As shown in the above-mentioned a new type of header, the steel bar 1 is provided with an end header 1-1 and a middle header 1-2, and the header is T-shaped. The structure of heading among the present invention also can be conical (as Figure 8 shown). The distance between the end header 1-1 and the middle header 1-2 is 30-100mm. If the distance between two heads is too large, raw materials will be wasted. If the distance is too small, the heads cannot be processed. Therefore, the distance between heads is 30-100mm.

Embodiment 2

[0075] Such as figure 2 As shown, the heading machine includes an upsetting oil cylinder 2-1, a hammer head cover 2-2, a hammer head 2-3, a clamping oil cylinder 2-4, a clamp 2-5, and a guide rail 2-6. The upsetting oil cylinder 2-1 is fixed on the upsetting machine 2, and the oil cylinder rod of the upsetting oil cylinder 2-1 is connected with the hammer 2-3; the described hammer cover 2-2 is fixed on the upsetting machine 2, The tup 2-3 can slide back and forth in the tup cover 2-2; as image 3 and Figure 4 As shown, the hammer head 2-3 can be a solid structure, and can also be a structure with a hammer head blind hole 2-3-1; as Figure 4 As shown, the blind hole 2-3-1 of the hammer head has a circular platform structure, the diameter of the deepest part of the blind hole 2-3-1 of the hammer head is small, and the diameter of the outlet of the end face of the hammer head 2-3 is relatively large, which is convenient for upsetting in the middle. When the head 1-2 is used,...

Embodiment 3

[0088] 1. After cutting the steel bar 1 to a fixed length, put the steel bar 1 between the symmetrically distributed reverse clamps 2-10 and the symmetrically distributed clamps 2-5, and the head end of the steel bar 1 is against the hammer head 2- 3 up;

[0089] 2. Afterwards, an upsetting instruction is issued, and the clamp 2-5 driven by the clamping cylinder 2-4 moves to the middle, clamps the steel bar 1, and the steel bar 1 is tightly clamped in the clamp groove 2-5-1; and At the same time, the reverse clamp 2-10 driven by the reverse clamp clamping oil cylinder 2-12 moves to the middle to clamp the steel bar 1, and the steel bar 1 is tightly clamped in the groove of the reverse clamp 2-10. The grooves of the fixture 2-10 and the fixture groove 2-5-1 are arranged in the same front and back and have the same structure;

[0090] 3. The power supply 2-13 connects the hammer head 2-3 to the reverse clamp 2-10 through the wire 2-14. When the steel bar 1 contacts the hammer h...

Abstract

The invention provides a novel upset head of an enhanced precast pile and a production method of the novel upset head. The novel upset head comprises a tail end upset head and a middle upset head, the tail end upset head is used for being clamped on a tensioning plate, the middle upset head is used for being clamped on an end plate, a replaceable hammer head is arranged on an upset head machine for producing the novel upset head, during first upset head machining, a main rib is inserted into the bottom of a blind hole of the hammer head with a blind hole, a control system controls a clamping oil cylinder to drive a clamp to clamp the main rib, and the main rib between the front end face of the hammer head and the clamp is extruded to form the middle upset head; and after the main rib is taken out, the hammer head is replaced with a solid hammer head for secondary upset head machining, the main rib between the front end face of the hammer head and the clamp is extruded to form the tail end upset head, and therefore machining of the novel upset head is completed. According to the method, the main rib with the double-upset-head structure can be produced, the problem that the end plate must be connected with the tensioning plate through bolts is solved, the production efficiency is improved, and the labor intensity of operators is reduced.

Description

technical field [0001] The invention relates to the production field of prefabricated components, in particular to a production method of a novel heading head. Background technique [0002] As a new building product, pretensioned concrete prefabricated piles are widely used in the construction of various industries. In order to improve the bending resistance of prefabricated pile products, it is necessary to install end plates with several countersunk holes at both ends of the prefabricated pile mold during the manufacturing stage of the steel cage, and the two ends of several longitudinal steel bars of the steel cage are processed with enlarged For head-shaped headers, the same number of headers on both sides are clamped in the counterbore of the end plates at both ends, and then the end plate at one end is fixed, and the tensioning bolts fix the tensioning plate and the end plate. The longitudinal reinforcement of the steel cage is stretched by the tension plate through t...
