Abstract

The utility model discloses a spinning machine for producing the mould of a lamp ornament and a lamp cover, which comprises a mould core (1) and a spinning mechanism. The spinning mechanism comprises a spinning head (2), a bottom base (3), a support rod (4), a movable rod (5), a sleeve cylinder (6), a support bracket (7) and an eccentric wheel (8). The eccentric wheel (8) is arranged on the support bracket (7). The sleeve cylinder (6) and the support bracket (7) are fixed together. The movable rod (5) is arranged in the sleeve cylinder (6). One end of the movable rod (5) pushes the eccentric wheel (8) and the other end fixes the support rod (4). The top end of the support rod (4) is provided with the spinning head (2) and the bottom base (3). The utility model has simple structure, low manufacture cost and short manufacture time.

Description

A kind of spinning apparatus of making the lamp decoration lampshade mould

The utility model belongs to a kind of device that thin sheet material is bent and formalizes, and relates in particular to a kind of spinning apparatus of making the lamp decoration lampshade mould.

At present, making the lamp decoration lampshade mould is that the stainless steel sheet material of 1.2mm comes out by punch ram with thickness generally, this method stresses speed certainly soon for producing in enormous quantities, but it is not too suitable producing with the phase for the small lot weak point, reason has: (1) must make diel, must be with No. 45 steel or chromium steel 62 and be used to make the diel material, and be about between the 4000-7000 unit with this material manufacturing cost, higher for the small lot cost; (2) diel itself also there is certain specification requirement: as reach certain precision etc., the time that therefore produces diel from receiving orders to is about 15 days, and the time is longer, and processing not too adapts to short-term; In addition, the update cycle of lamp decoration is generally good fast, can not adapt to fast-changing market with this process for stamping.

The utility model provides a kind of spinning apparatus that is used to make the glass lamp decoration lampshade mould.It is simple in structure, can make the mould of lampshade quickly and easily, and manufacturing cost is very low, and manufacturing time is short, and specification requirement is not high.

The utility model is achieved by the following technical solution: it comprises core rod that is installed on the lathe power transmission shaft and the spinning machine that is installed on the lathe saddle, wherein spinning machine comprises spinning head, base, support bar, motion bar, sleeve, support and eccentric wheel, eccentric wheel is installed in support one end and can rotates around fulcrum, sleeve and support are fixed together, motion bar be loaded in the sleeve and can be on the sleeve axis direction rectilinear motion, the guide-localization screw is installed in the guide groove on the motion bar, motion bar one end heads on eccentric wheel, the other end is mounted with support bar, spinning head is installed on the top of support bar, base is positioned at the rear of spinning head and is installed on the support bar by bearing, and spinning head and base are in the mobile restriction that is subjected to the limited block on the support bar on the axis direction.

The utility model compared with prior art has following advantage: 1: the turning processing that core rod of the present utility model needs only by engine lathe just can create, and the material of making is common A3 steel, the material of A3 steel is very cheap, make the big reduction of core rod and take about 200 to 500 yuan, cost is more than making stamping die according to cheap; 2: the specification requirement to core rod is not high, and as lower to specification requirements such as surface roughnesses, the time of making core rod is short, is about about 2 to 3 days, therefore is fit to very much the short-period production of small lot.

Below in conjunction with accompanying drawing the utility model is done detailed explanation:

Structural front view when Fig. 1 is the utility model use;

Fig. 2 is the vertical view of the utility model when removing tail stock for machine tool.

As Fig. 1, shown in Figure 2, the utility model comprises the core rod (1) that is installed on the lathe power transmission shaft (10) and is installed in spinning machine on the lathe saddle (11), wherein spinning machine comprises spinning head (2), base (3), support bar (4), motion bar (5), sleeve (6), support (7) and eccentric wheel (8), eccentric wheel (8) is installed in support (7) one ends and can rotates around fulcrum (9), sleeve (6) is fixed together with support (7), motion bar (5) be loaded on sleeve (6) lining and can be on sleeve (6) axis direction rectilinear motion, guide groove (12) lining on the motion bar (5) is equipped with guide-localization screw (13), motion bar (5) one ends head on eccentric wheel (8), the other end is mounted with support bar (4), spinning head (2) is installed on the top of support bar (4), base (3) is positioned at the rear of spinning head (2) and is installed on the support bar (4) by bearing (14), and spinning head (2) and base (3) are in the mobile restriction that is subjected to the limited block (15) on the support bar (4) on the axis direction.

The utility model is the mould that processes the lamp decoration lampshade as follows: 1: the shape of core rod (1) earlier according to the shaped design of the lamp decoration lampshade that will design, make material with the A3 steel then and on lathe core rod turning is come out; 2: as shown in Figure 1, core rod (1) is installed on the power transmission shaft (10) of lathe, then the sheet material (16) of the 1.2MM that makes the lamp decoration lampshade mould being installed in core rod (1) goes up and compresses with tail stock for machine tool (17), spinning machine is fixed on the knife rest (11) of lathe, start lathe, make core rod (1) be with sheet material (16) to rotate, follow rest (11) makes spinning head (2) arrive suitable position, rotate eccentric wheel (8) then and promote motion bar (5) toward moving left, make spinning head (2) press to core rod (1) to sheet material (16) all the time, utilize the long feed of knife rest (11), sheet material (16) finally is pressed on the surface of core rod (1), thereby obtains the mould of lamp decoration lampshade.
