Abstract

The utility model relates to a forming and pressing U die in a single process used for manufacturing the roller shell of an air-conditioning compressor. A platform is comprised; the platform is provided with a pair of deformed rollers whose circumferences are tangential; the two sides of the pair of deformed rollers are provided with rotating and returning spring for the deformed rollers; the outer circular arc surfaces of the deformed rollers are provided with a section of limit plane section for limiting the over-rotating of the deformed rollers during U pressing; the upper half part of the limit plane section is provided with an internal sunken circular arc surface; the pair of deformed rollers are symmetrically arranged taking the tangent as rotating shaft; the internal sunken circular arc surfaces of the pair of deformed rollers are connected with each other to from an internal sunken semi arc surface that is matched loosely with the outer circular arc surface of a U pressing hammer when in the limit position of U pressing; and the pair of deformed rollers are also provided with a splint with a U-shaped opening. Through the relevant rotation of a pair of deformed rollers during U shaping, two pressing boards of the utility model are driven to shut inward, thereby realizing U pressing in a single process and increasing the work efficiency of the production line.

Description

Produce the once-forming pressure U mould that compressor of air conditioner rolls cylindrical shell

Affiliated technical field:

The utility model relates to a kind of sheet material and presses the U mould, and specifically, it is a kind of once-forming pressure U mould that compressor of air conditioner rolls cylindrical shell of producing.

Background technology:

At present, domestic advanced compressor case manufacturing process is a kind ofly to roll the technology of cylindrical shell with sheet material, and it tailors into suitable size with sheet material earlier, again sheet material is made straight-tube shape, and then carries out the processing at straight tube two ends.The sheet material that wherein making the tube operation needs will cut out earlier is pressed into U-shaped, and then is molded into cylindrical shape.Existing pressure U mould is fixing U-shaped mould, as shown in Figure 6, this fixed mould 15 is after pressing U to finish, and because of the elasticity of workpiece material, the aperture of its U-shaped mouth is very big, i.e. state as shown in Figure 7, the U-shaped workpiece that this aperture is very big can't directly enter in the rounding mould, must add a procedure again, presses the U-shaped mouth little, therefore, reduced the operating efficiency of production line.

The utility model content

The purpose of this utility model is the shortcoming at prior art, and a kind of once-forming pressure U mould that compressor of air conditioner rolls cylindrical shell of producing is provided.

For achieving the above object, solution of the present utility model is as follows:

It has a platform, on this platform, be provided with the tangent profiled roller of a pair of circumference, the rotating shaft of this profiled roller is installed on the pedestal by bearing, described pedestal is fixed on the platform, be provided with the rotation return spring of profiled roller in the bilateral symmetry of a pair of profiled roller, one end of this return spring connects firmly on platform, its other end connects firmly on profiled roller, the exterior arc surface of described profiled roller is provided with one section spacing planar section, crossing of profiled roller rotated when being used to limit pressure U, the first half at this spacing planar section is provided with an interior concaved circular cambered surface, concaved circular cambered surface and 1/4th exterior arc surface loose fits of pressing the U hammer in being somebody's turn to do, described a pair of profiled roller is that an axial symmetry is installed with their tangent line, and when a pair of profiled roller being in press U rotary spacing position in it concaved circular cambered surface dock into one with press the U hammer exterior arc surface indent semicircle cambered surface of loose fit mutually, on described a pair of profiled roller, go back symmetry and connect firmly pair of U-shaped mouth clamping plate.

The further improvement project of the utility model is:

Above-mentioned pedestal is provided with the keeper of pressing the U workpiece.

By above-mentioned solution as can be seen, the utility model relatively rotates in pressing the U process by two profiled rollers, driving two pressing plates inwardly closes up, make the U-shaped mouth of workpiece become the closing in state, when workpiece leaves mould, just meet the aperture requirement of workpiece after the part resilience that U-shaped is young, thereby realized pressure U once-forming, save a procedure, improved the operating efficiency of production line.

The specific embodiment

Describe structure of the present utility model and operation principle in detail according to embodiment below.

Referring to Fig. 1,2, it has platform 1, a pair of profiled roller 2 is housed on this platform 1,2 ', this circumference to profiled roller is tangent, the rotating shaft 2-1 of profiled roller is installed on the pedestal 5 by bearing 4, and shaft end is by 6 sealings of axle sleeve lid, wherein piece number 7 is a sealing ring, described pedestal 5 is fixed on (as shown in Figure 2) on the platform 1, at a pair of profiled roller 2,2 ' bilateral symmetry is provided with it and rotates return spring 8,8 ', one end of this spring connects firmly on platform 1, its other end connects firmly at profiled roller 2, on 2 ', the exterior arc surface of described profiled roller is provided with one section outstanding spacing planar section 2-2,2 '-2, profiled roller 2 when being used for restriction pressure U, 2 ' cross rotated, the first half at this spacing planar section is provided with an interior concaved circular cambered surface 2-3,2 '-3, should hammer 14 1/4th exterior arc surface loose fits into shape with pressing U by interior concaved circular cambered surface, described a pair of profiled roller is that the rotating shaft symmetry is installed with their tangent line 10, and when a pair of profiled roller being in press U rotary spacing position in it concaved circular cambered surface dock into one and hammer the exterior arc surface indent semicircle cambered surface of loose fit mutually into shape with pressing U, symmetry also connects firmly pair of U-shaped mouth clamping plate 9 on described two profiled rollers, 9 ', described clamping plate 9,9 ' bottom is installed on the periphery of profiled roller with embedded mode, and then use bolting, it can be when pressing U profiled roller rotation and the U-shaped mouth of workpiece is pressed; In order to make workpiece before pressing U, obtain the location, on described pedestal 5, be provided with the place ahead keeper 11,11 ' and left and right keeper 12,12 ' of workpiece.

Referring to Fig. 3,4,5, when non-pressure U state, press the U hammer to lift, a pair of profiled
