Detailed Description

Specific examples of the present invention will be described in further detail below. It should be understood that the description herein of embodiments of the invention is not intended to limit the scope of the invention.

As shown in fig. 1 to fig. 2, it is the structure schematic diagram of the quick vertical clamping device of the multi-station cold heading forming machine provided by the present invention. The quick vertical clamping opening device of the multi-station cold heading forming machine comprises a containing box 10, two clamps 20 arranged on the outer side wall of the containing box 10 and a clamp control mechanism 30 arranged in the containing box 10. It is contemplated that the quick vertical clamping device of the multi-station cold heading machine further includes other functional modules, such as assembling components, mounting components, etc., which are well known to those skilled in the art and will not be described in detail herein.

The container 10 includes two spaced apart side walls 11 and a top wall 12 between the two side walls 11. It is contemplated that the container 10 may further include sidewalls (not shown) at other portions of the two sidewalls 11, which will not be described in detail herein. It is contemplated that the sidewalls 11 may be connected by fasteners such as screws, bolts, or may be secured by welding. The side wall 11 comprises a tapered portion 111. The tapered portion 111 is adapted to cooperate with the action of the gripper 20, that is, the gripper 20 has a tapered structure when gripping the material, so as to avoid interference during operation. The tapered portion 111 and the top portion 12 are located on both sides of the sidewall 11, which will be described in detail below.

The two clamps 20 have the same structure and are symmetrically arranged, and each clamp 20 comprises a clamping jaw 21, a connecting rod 22 arranged at one end of the clamping jaw 21, and a driven gear 23 fixedly arranged at the free end of the connecting rod 22. The other end of the clamping jaw 21 opposite to the connecting rod 22 is provided with a clamping opening 211. The shape of the nip 211 may be any shape, such as a half circle, a half hexagon, etc. The clamping opening 211 is used for clamping materials, so that the shape of the clamping opening 211 can be set according to actual needs. When the two jaws 211 are combined, they may form a complete circle or hexagon, thereby holding the material when closed. The link 22 is inserted into the side wall 11 and rotatably provided on the side wall 11. It is also conceivable to provide a bearing (not shown) between the connecting rod 22 and the side wall 11. The clamping jaw 21 is fixedly connected to the connecting rod 22 so as to be rotatable together with the connecting rod 22. The driven gear 23 and the clamping jaw 21 are respectively arranged at two sides of the side wall 11, namely, the driven gear 23 is arranged inside the accommodating box 10. The driven gear 23 acts as a gear, per se a prior art gear, and is not described in detail here. Two driven gears 23 are provided at intervals so that the clamping jaws 21 can be opened or closed.

The clamp control mechanism 30 includes a pull rod 31 inserted between the two driven gears 23, a stop strip 32 disposed on the pull rod 31, and a resilient member 33 sleeved on the pull rod 31 and clamped between the stop strip 32 and the top 12. The pull rod 31 is provided with a plurality of racks 311, and a stopper cap 312 provided at the other end of the pull rod 31. The plurality of racks 311 are respectively disposed on two sides of the pull rod 31 to couple with the two driven gears 23, and when the pull rod 31 is pulled up and down, the two driven gears 23 can be driven to rotate, so as to drive the clamping jaws 21 to rotate. When the pull rod 31 moves along the length direction thereof, the driven gear 23 is driven to rotate so as to enable the clamping mouths 23 of the clamping jaws 21 to be in an opening or closing state, therefore, the pull rod 31 does not need to be provided with a plurality of racks 311, and only needs to enable the clamping mouths 211 of the clamping jaws 21 to be in an opening or closing state. In order to enable the pull rod 31 to be pulled smoothly, the length direction of the pull rod 31 is perpendicular to a connecting line of the centers of the two driven gears 23. It is conceivable that a bearing is provided between the tie rod 31 and the top wall 12. One end of the pull rod 31 extends out of the top wall 12 to facilitate pulling by other equipment or by hand. The stop cap 312 is fixedly disposed on the pull rod 31 to prevent it from retracting into the container 10 under the urging of the resilient member 33. The resisting strip 32 is used for resisting against the return elastic member 33 and is arranged between the rack 311 and the return elastic member 33, so that the resisting strip 32 can move along with the pull rod 31. The resilient member 33 may be a spring sandwiched between the stop strip 32 and the top portion 12.

Compared with the prior art, the utility model provides a multistation cold heading machine's quick upper and lower clamping device is owing to have pull rod 31, and be provided with rack 311 on this pull rod 31, and this rack 311 meshes with driven gear 23 mutually, when the pulling alright in order to drive during the pull rod 31 driven gear 23 is rotatory, thereby can make two clamping jaw 21 opens, alright put into the material this moment in clamping jaw 21's the mouth 211, then release pull rod 31, pull rod 31 is just in reply the removal under the support of elastic component 33, and then make two clamping jaw 21 folds, thereby is in the material centre gripping in the mouth 211 of pressing from both sides, simultaneously, because the elasticity of replying elastic component 33 makes clamping mouth 211 is difficult to open automatically. Therefore, the clip opening device is simple and efficient when in use, and is beneficial to people to use, particularly to use manually.

The above description is only for the preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention, and any modification, equivalent replacement or improvement within the spirit of the present invention is encompassed by the claims of the present invention.
