Description
Technical field
This utility model relates to a kind of mould, particularly to the compound clamping that a kind of bend pipe bolt connects.
Background technology
Air-conditioner pipe Partial joints requires over nut bolt and connects, in the normal preparation technology route of existing screwed joint product, it is that first upsetting bolt carries out bend pipe operation again, namely upsetting connecting bolt technique is positioned at before bend pipe operation, as long as the length long enough of screwed joint, in bend pipe process, screwed joint will not be interfered with angle pipe equipment；And need screwed joint one end length in part pipeline bend pipe process too short due to circuit design, follow-up angle pipe equipment can be caused interference, and cannot be carried out bend pipe operation, by process route in turn, can only first carry out bend pipe operation, then carry out upsetting connecting bolt operation.And owing to, after carrying out bend pipe operation, pipeline has existed three-dimensional bending, be no longer straight tube, in order to ensure in upsetting connecting bolt operation, the space of pipeline screwed joint one end moves towards indeformable, then need compound clamping to ensure that what bend pipe upsetting connecting bolt worked is smoothed out.
Summary of the invention
The technical problems to be solved in the utility model is: the compound clamping providing a kind of bend pipe bolt to connect, and adopts this mould to ensure that being smoothed out of on bend pipe upsetting connecting bolt, solves above-mentioned prior art Problems existing.
The technical scheme solving above-mentioned technical problem is: the compound clamping that a kind of bend pipe bolt connects, including the first station expander clamping and the second station upsetting bolt clamping,
The first described station expander clamping is made up of two semicircle expander moulds separated, the middle part correspondence of each semicircle expander mould has groove I, during duty, the groove I of two semicircle expander moulds forms through hole I, and through hole I front end is that the bend pipe for clamping bend pipe being identical with bend pipe shape for the expander hole of expander, rear end clamps hole I；
The second described station upsetting bolt clamping is made up of two semicircle upsetting die bolts separated, the middle part correspondence of each semicircle upsetting die bolt has groove II, during duty, the groove II of two semicircle upsetting die bolts forms through hole II, and through hole II front end is that the bend pipe for clamping bend pipe being identical with bend pipe shape for the upsetting bolt hole of upsetting connecting bolt, rear end clamps hole II.
Described expander hole is followed successively by the large diameter hole section for pipe end bending and molding from front to back, for the expander hole section of expander with for the inclined hole section of linkage section between the extended diameter segment of molding and original diameter section.
The cross sectional shape of described upsetting bolt hole is rectangle.
This utility model is provided with the bend pipe for clamp bend pipe identical with bend pipe shape and clamps hole, ensure that the space of bend pipe three-dimensional bending is moved towards, guarantee that, in upsetting connecting bolt operation, the space of pipeline screwed joint one end moves towards indeformable, it is possible to ensure being smoothed out of on bend pipe upsetting connecting bolt work.Adopt this utility model mould can first bend pipe upsetting connecting bolt again, solve because air-conditioner pipe screwed joint one end length is too short, follow-up angle pipe equipment can be caused the problem interfered and first upsetting connecting bolt cannot be adopted to carry out bent tube technique again.
It addition, this utility model simple in construction, easy to operate, it is adapted in the manufacturing enterprise being correlated with and promotes the use of.
Below, in conjunction with the accompanying drawings and embodiments the technical characteristic of the compound clamping that the bend pipe bolt of this utility model connects is further described.

Detailed description of the invention
Embodiment 1: the compound clamping that a kind of bend pipe bolt connects, as Figure 1-Figure 4, including the first station expander clamping 1 and the second station upsetting bolt clamping 2,
First station expander clamping 1 is made up of two semicircle expander moulds 11 separated, the middle part correspondence of each semicircle expander mould has groove I 111, during duty, the groove I of two semicircle expander moulds forms through hole I 12, and through hole I front end is that the bend pipe for clamping bend pipe being identical with bend pipe shape for the expander hole 121 of expander, rear end clamps hole I 122；Described expander hole 121 is followed successively by the large diameter hole section 1211 for pipe end bending and molding from front to back, for the expander hole section 1212 of expander with for the inclined hole section 1213 of linkage section between the extended diameter segment of molding and original diameter section；
Second station upsetting bolt clamping 2 is made up of two semicircle upsetting die bolts 21 separated, the middle part correspondence of each semicircle upsetting die bolt has groove II 211, during duty, the groove II of two semicircle upsetting die bolts forms through hole II 22, and through hole II front end is that the bend pipe for clamping bend pipe being identical with bend pipe shape for the upsetting bolt hole 221 of upsetting connecting bolt, rear end clamps hole II 222.The cross sectional shape of described upsetting bolt hole 221 is rectangle.
Work process: this utility model needs to coordinate with corresponding punch forming plug, first by air-conditioner pipe on bolt sleeve, first station expander, bolt is moved to the position not affecting expander, air conditioner tube the first station expander clamping is clamped, then expander is carried out, the shape (as shown in Figure 5) similar to bolt bore end face is formed by the enlarged-diameter of air-conditioner pipe termination and by end face bends, first station upsetting bolt, bolt is moved to air-conditioner pipe termination then tight with the second station upsetting bolt clip die clamp, air-conditioner pipe termination and bolt upsetting are connect (as shown in Figure 6).
