The specific embodiment

In conjunction with Fig. 2, lifting transmission mechanism 4 provided by the invention comprises lifting cylinder 11, lifting frame 12, transmission of materials device 13 and motor and decelerator 14.Wherein, described transmission of materials device 23 is fixed on lifting frame 12, and the lower end of lifting cylinder 11 is arranged on the die shoe of press-fitting mould, and upper end is connected with lifting frame 12, and lifting cylinder 11 is positioned at the below of four jiaos of the dies of press-fitting mould.

In lifting transmission mechanism 4 of the present invention, lifting cylinder 11 is arranged on to the below of four jiaos of dies, because the position of four jiaos of described dies is higher, the installing space of lifting cylinder 11 is larger, therefore, can realize under existing mold shut height, guarantee the safe distance of lifting cylinder 11 and lathe table top, and be conducive to increase the stroke of lifting cylinder 11, avoid lifting transmission mechanism 4 to interfere with pre-springing cutter block and associated component 011 in the process of jack-up transmission product.Compared with prior art, the lifting transmission mechanism that the technical program provides is applied in press-fitting mould, has avoided changing the shut height of existing press-fitting mould, therefore can meet the requirement that a machine multi-vehicle-type swinging cross is produced, and has also saved the cost of frock exploitation simultaneously.

Accuracy and the stationarity lifted in order to strengthen lifting transmission mechanism, lifting transmission mechanism 1 provided by the invention has lead 15, and this lead 15 comprises coupling part 21 and targeting part 22.In specific implementation process, the height of lead 15 and above-mentioned connection, the two-part height that leads can design according to specific needs.

Wherein, the coupling part 21 of lead is fixedly connected with lifting frame 12, and in the present embodiment, coupling part 21 is provided with screw thread, is threaded connection with lifting frame 12 fixingly, and this connected mode makes the processing of lead 15 and lifting frame 12, assembling process easy.Pilot hole matched in clearance on the targeting part 22 of lead and the die shoe of press-fitting mould.

Particularly, the mode such as also can being bolted of above-mentioned lead 15, welding is fixed on lifting frame 12.

In order to guarantee good guide effect, can be set to two groups or more by above-mentioned lead, the arrange form of each lead in lifting transmission mechanism 1 can be determined according to real needs.

In technique scheme, lifting frame 12 can directly adopt the form of monoblock lifting installing plate, but this form less stable.For addressing this problem, the lifting frame 12 of lifting transmission mechanism 1 provided by the invention is the frame structure being welded into by polylith steel material, as shown in Figure 7.Wherein, lifting frame 12 is higher with the position that lifting cylinder 11 is connected, to facilitate the installation of lifting cylinder 11.Polylith steel material splices by the mode of welding, makes lifting frame 12 present irregular frame structure.So arrange, strengthened the stability of above-mentioned lifting frame.

In order to make the structure of above-mentioned lifting transmission mechanism 1 compacter, arrangement convenience, in the present embodiment, will between the transmission axle at transmission of materials device 13 and horizontal line, be provided with an angle that is less than 90 degree, the whole transmission of materials mechanism that makes that transmission of materials device 13 and motor and decelerator 14 form is V-shaped.

Above-mentioned material transmitting device 13 is fixedly connected with lifting frame 11, and particularly, both can adopt welding, riveted joint, or other connected modes, with bolts in the present embodiment, to facilitate the dismounting of transmission of materials device 13, be convenient to this lifting transmission mechanism to be applied to the course of conveying that lifts of differential profiles.

For guaranteeing lifting cylinder 11 response and the whole stationarity of lifting process fast, described lifting cylinder 11 is selected induction cylinder, and all lifting cylinders 11 in lifting transmission mechanism 1 adopt the mode of series connection.When lifting cylinder 11 receives after jack-up signal, all lifting cylinders are moved simultaneously, realize lifting of lifting frame 12.

Lifting transmission mechanism 1 of the present invention is by changing jack-up power source and arrangement, guidance mode etc., realize under existing mold shut height, meet the safe distance of lifting cylinder 11 and lathe table top, and guaranteed that product assembly do not interfere with the pre-springing cutter block of opening and associated component 011 in jack-up transmitting procedure.Especially for the production of V-type press-fitting mould product, compared with prior art, press-fitting mould provided by the invention can solve in prior art scheme, can not realize that a machine multi-vehicle-type swinging cross produces problem, reduced the cost of frock exploitation.

Although the present invention is described in conjunction with above-described embodiment, but the present invention is not limited to above-described embodiment, and being only subject to the restriction of claim, those of ordinary skills can easily modify to it and change, but do not leave essence design of the present invention and scope.
