[0022] The technical solutions in the embodiments of the utility model will be apparently and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.

[0023] With reference to Figures 1-6 The quick die changing screw head striking machine comprises a base 1, a machining table 11 rotatably connected to the upper end of the base 1, a side plate 2 fixedly connected to the upper end of the base 1, a head striking block 4 connected to the side plate 2 through an extension mechanism, a plurality of clamping grooves 12 formed in the end face of the machining table 11, a plurality of head striking dies 13 clamped in the plurality of clamping grooves 12, a device cavity 14 formed in the machining table 11, a plurality of sliding grooves 15 formed in the inner wall of the device cavity 14 and each in communication with the inner part of the adjacent clamping groove 12, a piston 18 slidably connected in the sliding groove 15, a plug rod 17 fixedly connected to one end of the piston 18 and inserted into the corresponding head striking die 13, and a sliding mechanism mounted on the outer wall of the machining table 11 and used for driving the plurality of plug rods 17 to slide synchronously.

[0024] Specifically, the plurality of plug rods 17 are driven to slide synchronously by means of the sliding mechanism, so that the consistency and stability of the replacement of the head striking dies 13 are ensured, and the efficiency during dismounting and mounting is improved. It should be noted that a driving motor is mounted at the lower end of the base 1 and used for driving the machining table 11 to rotate.

[0025] The sliding mechanism comprises an air pump 5 mounted on the end face of the machining table 11, an air inlet and outlet pipe of the air pump 5 in communication with the inner part of the device cavity 14, and a limiting ring 16 arranged at the slot opening of the sliding groove 15 and having an inner diameter smaller than the outer diameter of the piston 18.

[0026] Specifically, the device cavity 14 is filled with air by means of the air pump 5, so that the plurality of pistons 18 are synchronously driven to slide towards the clamping grooves 12, the plug rods 17 are synchronously inserted into the corresponding head striking dies 13, and the head striking dies 13 are fixed. When dismounting, the device cavity 14 is in a negative pressure state by means of the air pump 5, so that the plug rods 17 are driven to slide towards the axis of the machining table 11, and the plurality of head striking dies 13 are released from the fixation.

[0027] The extension mechanism comprises a hydraulic oil cylinder 3 fixedly connected to the lower end face of the side plate 2, the head striking block 4 fixedly connected to the extension end of the hydraulic oil cylinder 3, a plurality of ejector rods 6 slidably connected to the lower end of the machining table 11 and each extending into the head striking die 13, and a fixing plate 9 fixedly connected to the outer wall of the ejector rod 6.

[0028] Specifically, the ejector rod 6 can be used to eject the finished product after the head striking is completed, so that the trouble of manual taking is avoided, and the production efficiency is improved.

[0029] The end of the ejector rod 6 is provided with a ball 10, the outer wall of the ejector rod 6 is sleeved with a spring 8, one end of the spring 8 is fixedly connected with the end face of a fixed plate 9, the other end of the spring 8 is fixedly connected with the lower end face of a machining table 11, the upper end face of the base 1 is fixedly connected with a top block 7, the outer wall of the top block 7 is T-shaped and is smoothly transitioned at the edge;

[0030] Specifically, the design of the ball 10 reduces the friction between the ejector rod 6 and the base 1, and improves the smoothness of the ejection action. The spring 8 can automatically reset the ejector rod 6 after the ejection action is completed, reducing the need for manual intervention. The setting of the top block 7 can eject the screw in the head forming die 13 when the ejector rod 6 slides to the top block 7.

[0031] In the utility model, when the device is used, first, the screw blank to be processed is placed in the head forming die 13 on the machining table 11. The machining table 11 is driven to rotate by the driving motor on the base 1, so that the plurality of head forming dies 13 can be aligned with the head forming block 4 in turn, so that continuous screw head forming operations can be performed.

[0032] In the initial state, the air pump 5 is not started, the device cavity 14 is in a normal pressure state, the inserting rod 17 is kept in the initial position under the action of the piston 18, and the head forming die 13 is not fixed. At this time, the operator can clamp different head forming dies 13 into the clamping groove 12 at the end face of the machining table 11 according to production needs.

[0033] When the head forming die 13 needs to be fixed, the operator starts the air pump 5. The air pump 5 injects gas into the device cavity 14, and pushes the plurality of pistons 18 to slide along the sliding groove 15 to the direction of the clamping groove 12. The piston 18 drives the inserting rod 17 to move synchronously, the inserting rod 17 is inserted into the corresponding head forming die 13, and the quick fixing of the die is realized. The design of the limiting ring 16 ensures that the piston 18 will not be separated from the sliding groove 15 during the sliding process, and the stability and safety of the equipment are improved.

[0034] After the die is fixed, the operator starts the hydraulic oil cylinder 3. The telescopic end of the hydraulic oil cylinder 3 drives the head forming block 4 to move downward, and the head forming operation of the screw blank is performed. When the screw head forming is completed, the hydraulic oil cylinder 3 drives the head forming block 4 to reset. Then the driving motor drives the machining table 11 to rotate, drives the next group of head forming dies 13 to rotate to the head forming block 4 for head forming, and the top rod 6 and the top block 7 below the processed workpiece contact and move upward. The design of the ball 10 reduces the friction between the top rod 6 and the top block 7, so that the ejection action is more smooth. The ejector rod 6 ejects the formed screw from the head forming die 13, avoids the trouble of manual picking, improves the production efficiency. After the ejection action is completed, the spring 8 automatically resets the ejector rod 6, so that it returns to the initial position and is ready for the next ejection action.

[0035] In summary, the device realizes efficient, accurate and stable processing of screw head forming. The sliding mechanism driven by the air pump 5 and the head block 4 driven by the hydraulic oil cylinder 3 work together to ensure the rapidity and consistency of the mold replacement and screw forming. The design of the ejector rod 6 and the spring 8 further simplifies the operation process, reduces manual intervention and improves production efficiency.
