In the illustration, the mechanism for driving the sliding base 3 to slide relative to the platform 2 is a screw rod sliding block mechanism, wherein the first motor 21 drives the screw rod 22 to rotate, and the sliding base 3 is equivalent to a sliding block. The lead screw sliding block mechanism is selected as a transmission mode for driving the sliding seat 3 to move relative to the platform 2, and the control progress of the transmission mode is higher, and the response speed is high. The sliding seat 3, the first motor 21 and the lead screw 22 are all arranged on the platform 2 and can move up and down synchronously with the platform 2. The connecting arm 4 is mounted on the slide carriage 3, can slide horizontally in synchronization with the slide carriage 3, and can rotate in a horizontal space relative to the slide carriage 3, and the angle of each rotation is an integer multiple of 180 degrees. The power device for driving the connecting arm 4 to rotate relative to the sliding seat 3 in the drawing is a motor II 31, which is arranged on the sliding seat 3, an output shaft acts with the left end of the connecting arm 4 (a gearbox can be arranged on the sliding seat as an intermediate speed changing mechanism between the motor II 31 and the connecting arm 4. The turnover condition of the lower clamping plate 51 (namely the hand grip 5) is controlled by the motor II 31, the lower clamping plate 51 can be rotated 180 degrees in a single forward direction by setting, the upper plate surface and the lower plate surface are compared, then rotated 180 degrees in a reverse direction for resetting, and the lower clamping plate 51 can be rotated only in the forward direction or the reverse direction by setting, and each time is 180 degrees.

Preferably, the pivot shaft may be externally sleeved with a sleeve, and the sleeve is of an elastomeric material to facilitate a certain radial displacement of the upper clamp plate 52 during rotation, or in other embodiments, to provide a clearance fit relationship with the shaft bore of the pivot shaft 522.
As shown in fig. 1 to 6, a connecting end a51a of the lower clamping plate 51 is matched with a linear rail (dovetail groove-rail structure) arranged vertically between the U-shaped clamping plate a51b, and a fastening adjusting part (i.e. fastening bolts 511 on two sides) capable of selectively limiting the vertical fixing position of the U-shaped clamping plate a51b is arranged on the connecting end a51 a. The arrangement can adjust the distance between the opposite plate surfaces of the U-shaped clamping plates A51B and the U-shaped clamping plates B52B (when the opposite plate surfaces of the two clamping plates are in the horizontal plane).
In order to improve the clamping effect of the grippers 5 on the forging, as shown in fig. 7, the lower end surface (i.e., the bottom surface c) of the U-shaped clamping plate B52B on the upper clamping plate 52 is an inclined surface inclined from the outside to the inside (right to left in the drawing). The angle between the inclined plane and the horizontal plane is not more than 30 degrees, preferably 1 degree to 15 degrees, such as 2 degrees, 3 degrees, 5 degrees, etc.
Also, to improve the clamping effect of the gripper 5 on the forging, the following schemes may be adopted as shown in fig. 8 to 10:
a plurality of threaded through holes are alternately distributed on the two arm plates of the U-shaped clamping plate B52B in the upper clamping plate 52 along the length direction of the arm plates, and pressing columns 53 are correspondingly arranged in the threaded through holes. An end block 531 is fixedly arranged at one end of the pressing column 53, and the lower end surface of the end block 531 can extend downwards relative to the lower plate surface of the arm plate. The end block 531 is made of a high temperature resistant elastic material (most preferably a composite material). The "high temperature" is a high temperature suitable for the forging temperature 3, and the lowest temperature boundary value capable of being at the high level needs to be specifically determined according to the forging environment, and is generally 800 degrees, even 1000 degrees or more than 1200 degrees. To ensure sufficient rigidity of the two arms of the U-shaped clamping plate B52B, rib plates 532 are disposed on the two arms along the length direction of the arms.
The two arm plates of the U-shaped clamping plate A51b in the lower clamping plate 51 are respectively provided with a strip-shaped sinking groove on the lower plate surface of each arm plate. The strip-shaped sinking groove is internally provided with a supporting plate 54 capable of sliding along the groove depth direction of the strip-shaped sinking groove, and the notch of the strip-shaped sinking groove is provided with a sealing plate 58. The seal plate 58 is provided with a plurality of lower adjusting screws 56, the screw ends of the lower adjusting screws 56 extend into the strip-shaped sinking grooves and are correspondingly sleeved with springs 57, and the other ends of the springs 57 are pressed on the lower plate surface of the supporting plate 54. Meanwhile, on the two arm plates of the U-shaped clamping plate a51b in the lower clamping plate 51, a plurality of upper adjusting screws 55 are respectively arranged on the upper plate surface of each arm plate in an alternate manner, the screw ends of the upper adjusting screws 55 can act on the upper plate surface of the supporting plate 54, and strip-shaped through holes are respectively arranged on the two sides of the upper adjusting screws 55. The upper plate surface of the supporting plate 54 is distributed with strips 541, and the strips 541 can pass through the strip through holes to the outside of the upper end surface of the arm plate of the U-shaped clamping plate a51 b. Preferably, the upper portion of the bar 541 is provided with a toothed end 541a. That is, the bar 54 can be exposed to the outside of the arm plate upper end surface of the U-shaped clamp plate A51b in the lower clamp plate 51 in a tooth-like structure. The bar 54 is preferably made of a high temperature resistant elastic material, and if the upper part of the bar is of a non-toothed structure, the material of the bar is preferably made of a high friction coefficient so as to ensure that a sufficient contact friction force can be formed when the bar contacts with the forging.
The end block 531 at the lower end of the pressing column 53 can act on the surface of the forging, and the lower end surface of the pressing column 53 (i.e. the upper end block 531) extends downwards from the pressing column 53 at the free end of the arm plate of the U-shaped clamping plate B52B (from right to left in the drawing) in a generally decreasing order. Even if the stamping slitter edge of the forging is very uneven, the claw 5 can stably clamp the forging (after the ejector rod jacks up the forging after forging and hammering, the claw stretches into the lower part of the forging, and the forging is clamped by falling under the action of the slitter edge on the periphery of the forging main body, so that the scheme of the novel forging press is particularly suitable for grabbing and overturning the strip-shaped forging). The elastic deformation of the end block 531 can enhance the action pressure between the clamping plate and the waste edge of the forge piece on one hand, and the static friction force between the contact surfaces can be increased on the other hand, so that the forge piece slides off from the grip 5 in surface overturning, and the quick overturning operation is facilitated.
The upper adjusting screw 55 can adjust the height of the upper part of the bar 541 extending out of the U-shaped frame plate A51 b. The U-shaped frame plate A51b is provided with a stepped counter bore corresponding to the upper adjusting screw 55, the lower section of the stepped counter bore is a threaded hole, the nut part of the upper adjusting screw 55 is arranged in the upper section hole of the stepped counter bore, and an axial vertical distance is reserved between the upper end face of the nut and the upper port of the stepped counter bore. The lower adjusting screw 56 can adjust the initial compression of the spring 57, namely the elastic pressure exerted by the spring 57 on the supporting plate 54, so as to control the pressure of the upper end surface of the bar 541 on the waste edge of the forging piece. In the illustration, one side (the outer side) of each arm plate is provided with one bar, the other side (the inner side) is provided with two bars, in a specific embodiment, the two sides can be provided with a plurality of bars, the numbers of the bars at the two sides can be consistent or different, and the number of the bars at the inner side is generally greater than the number of the bars at the outer side.
As in the case of the press stud 53 used simultaneously with the bar 541. In an embodiment, the pressing column 53 and the bar 541 may be alternatively used. When the forging is required to be turned (180 degrees) quickly, the scheme shown in the figure is preferably selected.
As shown in fig. 1, 6 and 6, one end of the connecting arm 4 is provided with a shaft 42, the other end is provided with a U-shaped insertion plate 41, a connecting plate 43 extending horizontally is provided above the end provided with the insertion plate 41, and a vertically extending end plate is provided below the end provided with the insertion plate. The two side surfaces of the connecting end a51a of the lower clamping plate 51 are provided with slots 512 which can be inserted into the plugboard 41. The connection plate 43 is connected to the top surface a of the connection end a of the lower clamping plate 51 by bolts, and the end plate is connected to the side surface b of the connection end a of the lower clamping plate 51 by double-headed screws 44. The suspension rigidity of the lower clamping plate 51 can be guaranteed through the arrangement, the lower clamping plate 51 can be parallel to the horizontal plane after long-term use, and therefore firmness and reliability effects of clamping the forge piece can be maintained for a long time.
As shown in fig. 7, the second driving unit 6 is a cylinder rod (a hydraulic cylinder rod or a pneumatic cylinder rod). One side of the connecting end B52a of the upper clamping plate 52 is provided with a pushing arm 523, the pushing arm 523 is obliquely arranged from outside to inside and downward, and the outer end of the pushing arm 523 is connected with a pressure cylinder rod. By means of the arrangement, acting force effect between the U-shaped clamping plate B52B and the waste edges of the forge pieces can be improved, and grabbing stability and reliability of the grab handles 5 on the forge pieces are enhanced.
