Description

Technical Field

[0001] The utility model relates to the technical field of compressor housing processing, in particular to a flaring die for a compressor housing. Background Technique

[0002] A compressor is a driven fluid machine that raises low-pressure gas to high-pressure gas and is the heart of a refrigeration system. When producing a compressor housing, in order to ensure that the end opening size at the rear end of the compressor housing matches the size of the compressor housing end cover and enable the compressor housing to meet the production requirements of the next-level processing and assembly of the product, it is necessary to perform flaring treatment on the end opening of the compressor housing.

[0003] In the prior art, when flaring a compressor housing, the housing is usually clamped and fixed by a pair of arc-shaped clamping plates, and then a conical head is driven by a hydraulic cylinder to flare the compressor housing. However, the clamping of the housing by only a pair of arc-shaped clamping plates is not stable enough, and it is easy for the conical head to push the end of the housing away during the flaring of the housing, reducing the flaring quality of the compressor housing. Moreover, the efficiency of simply driving the conical head by a hydraulic cylinder to flare is low, and it is easy to cause deformation of the flared housing. Content of the Utility Model

[0008] Furthermore, the clamping assembly includes a chute provided in the middle of the upper end of the bottom plate. A pair of symmetrically arranged sliders are slidably connected in the chute.

[0010] Further, there is a distance between the opening of the compressor housing and the ends of a pair of the arc-shaped positioning plates.

[0022] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0023] Embodiment 1

[0024] Combined with the attached Figure 1 A flaring die for a compressor housing includes a bottom plate 1 and a compressor housing 3. In the middle of the upper end of the bottom plate 1, a clamping assembly 2 for horizontally clamping and fixing the compressor housing 3 is installed. On one side of the upper end of the bottom plate 1, an auxiliary positioning assembly 4 acting on the bottom wall of the compressor housing 3 is installed. On the other side of the upper end of the bottom plate 1, a support plate 5 is installed. Outside the support plate 5, a hydraulic cylinder 6 is installed. The output end of the hydraulic cylinder 6 passes through the support plate 5 and is connected to a frame 7. Inside the frame 7, a motor 8 is installed. The output end of the motor 8 passes through the side wall of the frame 7 and is connected to a conical heating head 9.

[0025] Combined with the above structure, the conical heating head 9 is driven by the motor 8 to rotate, and the compressor housing is flared by the conical heating head 9, improving the flaring rate.

[0026] Combined with the attached Figure 3 The clamping assembly 2 includes a chute 101 provided in the middle of the upper end of the bottom plate 1. Inside the chute 101, symmetric sliders 10 are slidably connected in the front and back. Between the front and back walls of the chute 101, a threaded rod 11 threadedly connected to the slider 10 is connected by bearings. The threaded hole directions on a pair of sliders 10 are opposite. At the front end of the bottom plate 1, a second motor 12 connected to the threaded rod 11 is installed. At the upper end of the slider 10, an L-shaped connecting rod 13 is fixed. The top of the L-shaped connecting rod 13 is connected to arc-shaped positioning plates 14 with opposite slot openings.

[0027] Combined with the above structure, when the clamping assembly 2 is used, the second motor 12 is started to drive the threaded rod 11 to rotate, so that a pair of sliders 10 slide relative to each other in the chute 101, so that a pair of arc-shaped positioning plates 14 clamp and fix the compressor housing, facilitating flaring.

[0028] Combined with the attached Figure 3 , a rubber pad 15 is fixed inside the arc-shaped positioning plate 14. The compressor housing 3 is located between a pair of the rubber pads 15. The friction between the arc-shaped positioning plate 14 and the compressor housing is increased through the rubber pads 15, so that the compressor is stably clamped and fixed.

[0029] Combined with the attached Figure 1 , there is a distance between the opening of the compressor housing 3 and the ends of a pair of the arc-shaped positioning plates 14, leaving a certain margin for the flaring of the compressor housing.

[0030] Combined with the attached Figure 2 , the auxiliary positioning assembly 4 includes a second support plate 16 installed on the upper left side of the bottom plate 1. A second threaded rod 17 is horizontally passed through and threadedly connected to the second support plate 16. One inner end of the second threaded rod 17 is rotatably connected to a second positioning plate 18 that contacts the bottom end of the compressor housing 3. The other end of the second threaded rod 17 is connected to a turntable 19.

[0031] Combined with the above structure, when the auxiliary positioning assembly 4 is used, the turntable 19 is rotated to make the second threaded rod 17 rotate, so that the second threaded rod 17 drives the second positioning plate 18 to move horizontally, making the second positioning plate 18 contact the bottom end of the compressor housing 3, thereby preventing the compressor housing 3 from moving horizontally when the housing is flared, resulting in the failure of flaring; at this time, the second threaded rod 17 continues to rotate, and the second positioning plate 18 rotatably connected thereto does not rotate because it contacts the bottom end of the housing, preventing damage to the bottom end of the housing.

[0032] Embodiment 2

[0033] On the basis of Embodiment 1, combined with the attached Figure 4 , the conical heating head 9 includes a heat insulation plate 20 connected to the output end of the motor 8. A conical metal head 21 is fixed to the end of the heat insulation plate 20. A heating plate 22 is inserted and fixed in the conical metal head 21. A power supply 23 electrically connected to the heating plate 22 is installed on the other side of the heat insulation plate 20.

[0034] Combined with the above structure, the power supply 23 provides energy for the heating plate 22, and the heating plate 22 heats the conical metal head, improving the efficiency of flaring the compressor housing.

[0035] The specific usage method is as follows:

[0036] Place the compressor housing between a pair of arc-shaped positioning plates 14. Start the second motor 12 in the clamping assembly 2 to rotate the threaded rod 11, so that a pair of sliders 10 slide relative to each other in the chute 101, thereby clamping and fixing the compressor housing with a pair of arc-shaped positioning plates 14. A certain margin is left at the end of the arc-shaped positioning plate for flaring the compressor housing; rotate the turntable 19 of the auxiliary positioning assembly 4 to rotate the second threaded rod 17 and then drive the second positioning plate 18 to move horizontally, so that the second positioning plate 18 contacts the bottom end of the compressor housing 3, preventing the compressor housing from moving horizontally when flaring the housing, resulting in flaring failure; drive the conical heating head 9 to move towards the end of the housing through the hydraulic cylinder 6, and start the motor 8 to drive the conical heating head 9 to rotate, and heat the conical metal head through the heating plate 22, improving the efficiency of flaring the compressor housing.

[0037] The above describes the present invention and its implementation manners. Such description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present invention, and the actual structure is not limited thereto. All in all, if those of ordinary skill in the art are inspired by it and, without departing from the gist of the present invention, design similar structural manners and embodiments to this technical solution without creative efforts, they shall fall within the protection scope of the present invention.
