The top of the outer side of the punching box 7 corresponds to two ends of the movable plate 27 and is fixedly connected with guide posts 29 along the vertical direction, the movable plate 27 is sleeved on the guide posts 29 in a sliding mode, and the guide posts 29 can play a role in guiding, so that the movable bearing block and the fixed bearing block are accurately matched. The fixed bearing block and the movable bearing block are provided with compression ring grooves matched with the outer diameter of the steel bar a in pairs, the steel bar a falls into the compression ring grooves in the fixed bearing block, and the steel bar a is extruded by downward movement of the movable bearing block.

The transverse punching mechanism 23 comprises a punching block arranged towards the fixed bearing block, the punching block is in driving connection with the first air cylinder 10 fixed on the outer wall of the punching box 7, a punching opening concentric with the pressing ring groove is formed in one side, facing the fixed bearing block, of the punching block, after the steel bar a is fixed by the radial punching mechanism 30, the first air cylinder 10 is started to drive the transverse punching mechanism 23 to move towards the two ends of the steel bar a, and the steel bar a completes pier head operation under the cooperation of the transverse punching mechanism 23 and the radial punching mechanism 30.

As shown in fig. 1, a feeding plate 3 for conveying the steel rods a to the stamping mechanism is further arranged at the top of the bottom plate 1, a storage box 6 for storing the steel rods a is supported and fixed between the feeding plate 3 and the stamping box 7 through a support frame 5, and the steel rods a are orderly placed inside the storage box 6 from top to bottom. The top and the bottom of storage case 6 all are the opening form, and the opening part both sides at storage case 6 top are the slope structure setting, make things convenient for the feeding. The heating zone that is used for carrying out heat treatment to rod iron a is formed to the inside of storage case 6, and the heating zone is formed through installing the resistance wire on storage case 6 inner wall, and all rod irons a are put into to storage case 6 inside back and are all heated treatment, can shorten rod iron a's process time. Go up flitch 3's inside parallel and seted up three groups and the flourishing silo 4 of excellent a shape looks adaptation of steel, go up flitch 3 along the horizontal linear motion of the length direction of bottom plate 1 and tangent with the opening of storage case 6 bottoms, it needs to explain that, flourishing silo 4 degree of depth here need guarantee to hold excellent a of steel completely, fall into to the inside back of one of them flourishing silo 4 when excellent a of steel, and the whole flitch 3 of going up can also follow the opening part of storage case 6 bottoms and carry out smooth slip. A notch corresponding to the material moving mechanism 25 is formed in the middle of the material feeding plate 3, and the notch is arranged to prevent the material moving mechanism 25 from interfering with the material feeding plate 3 when the material feeding plate 3 moves upwards after entering the inside of the stamping box 7. Go up flitch 3 to the inside punching press mechanism motion process of punching press case 7, at first through storage case 6, the inside rod iron a that heats of storage case 6 firstly falls into to three flourishing silo 4, and rod iron a moves upward through moving material mechanism 25 and falls into to moving material mechanism 25 afterwards in, moves down through second cylinder 24 drive moving material mechanism 25 and falls into to fixed carrier block at last.

Because the application selects the feeding plate 3 to send the steel bar a in the storage box 6 into the stamping box 7, if the scheme is adopted, in the process that the feeding plate 3 returns to the initial position, the steel bar a inside the storage box 6 falls into the material containing groove 4, and the stamping mechanism inside the stamping box 7 performs head upsetting operation on the steel bar a at the moment, so that the steel bar a falling into the material containing groove 4 too early has temperature loss, not only heat waste is caused, but also the forming of the heads is influenced, in order to avoid the above situation, a rectangular groove communicated with the notch is formed in the middle of the feeding plate 3, as shown in fig. 4 and 5, the communication part between the rectangular groove and the notch is of an arc-shaped structure, a sliding plate 15 is slidably installed inside the rectangular groove along the length direction of the feeding plate 3, the top of the sliding plate 15 is flush with the feeding plate 3, one end of the sliding plate 15 facing the material containing groove 4 is elastically connected with a stop block 16 along the vertical direction, the stop block 16 faces one side of the storage box 6, and when the sliding plate 15 is in contact with the sliding plate 6, and the sliding plate 15 can be retracted to the bottom, and the sliding plate can be recovered to the storage box 6, and the sliding plate 15 can be recovered to the original position, and the sliding plate 15.

Furthermore, two side walls inside the rectangular groove are also provided with guide grooves 19 parallel to the groove bottom, two sides of one end of the sliding plate 15 away from the stop block 16 are fixedly connected with sliding columns 44 matched with the guide grooves 19, and the sliding columns 44 are embedded into the guide grooves 19 and are in sliding fit connection with the guide grooves 19. The interior of the feeding plate 3 is further formed with a spring groove 17 communicated with the rectangular groove along the length direction thereof, a spring 18 is arranged in the spring groove 17, one end of the spring 18 is connected with the inner side end of the spring groove 17, the other end of the spring is connected with the sliding plate 15, and the restoring force direction of the spring 18 faces to the side departing from the sliding plate 15. When the scheme is implemented, when the feeding plate 3 moves towards the inside of the stamping box 7, the feeding plate 3 firstly passes through the bottom of the storage box 6, three steel bars a inside the storage box 6 respectively fall into three material containing grooves 4, the feeding plate 3 continuously moves forwards, the stop block 16 is contacted with the bottom of the storage box 6, the stop block 16 retracts into the sliding plate 15 under the action of the storage box 6 at the moment, the feeding plate 3 is ensured to smoothly pass through the storage box 6, after the steel bars a are transmitted to the inside of the fixed bearing block, the feeding plate 3 starts to return at the moment, the stop block 16 is blocked by the storage box 6 after being contacted with the storage box 6, the feeding plate 3 continuously returns, the sliding plate 15 is kept still at the moment, the sliding plate moves towards one side of the material containing grooves 4 relative to the rectangular groove, the steel bars a inside the storage box 6 cannot fall into the material containing grooves 4 due to being blocked by the sliding plate 15, the continuous heating treatment inside the storage box 6 is ensured, and the heat loss caused by the fact that the steel bars a too early enter the material containing grooves 4 is avoided.
