Of course, when in use, it is only necessary to press the pressing head down in advance to the required height of the matching blank. A limiting mechanism for fixing the swinging position of the pressing swing arm is installed on the pressing support frame. More specifically, the pressing base includes a fixed bottom plate E10, which is fixed on the pressing support frame, and hinge plates E10 are symmetrically arranged on the fixed bottom plate. 11, one end of the material pressing swing arm is rotatably connected between the upper ends of the two hinged plates, the material pressing head mechanism is movably connected to the other end of the material pressing swing arm, the limiting mechanism includes a vertical screw E 12, a horizontal screw mounting plate E 13 is provided on the middle part of the material pressing swing arm, screw holes are provided on the screw mounting plate corresponding to the screw, the lower end of the screw extends downward out of the screw mounting plate and abuts against the material pressing support frame, the upper end of the screw is provided with a turntable E 14 for driving the screw to rotate, a handle E15 is installed on the side of the turntable, when in use, the turntable is rotated by rotating the handle, and then the screw is driven to rotate to realize the rotation of the material pressing swing arm, the lower end of the screw is only abutted against the material pressing support frame under the action of gravity, so due to the swinging of the material pressing swing arm, the lower end of the screw will move adaptively without interference.

[0050] In this embodiment, in order to realize the material pressing, the material pressing head mechanism includes a horizontally arranged rotating shaft E16, the rotating shaft and the material pressing swing arm are perpendicular to each other, one end of the rotating shaft is rotatably connected to the end of the material pressing swing arm, and the other end is installed with a roller E17, the roller rotates synchronously with the rotating shaft. When in use, when the front end of the outputted blank bounces up at the docking position, it will first hit the lower outer wall of the roller, and then due to the initial velocity in the horizontal direction, the blank will move along the outer peripheral surface of the lower side of the roller and will not bounce up. At the same time, since the roller and the rotating shaft rotate synchronously, the movement of the blank will also drive the movement of the rotating shaft, which is convenient for the smooth transportation of the blank. More specifically, a rotating seat E18 is provided on the end of the material pressing swing arm corresponding to the rotating shaft, and a rotating hole E19 is provided on the rotating seat corresponding to the rotating shaft. The rotating hole passes through the material pressing swing arm, and the non-roller end of the rotating shaft is rotatably connected to the rotating hole.

[0051] In this embodiment, since the roller will continuously contact each heated blank during the processing, the temperature of the roller will continuously increase. The cooling mechanism includes a cooling tube E20, one end of the cooling tube is closed, and the other end is internally screwed with a plug E21, a connecting hole E22 is provided in the middle of the plug, and connecting tubes E23 connected with the connecting holes are provided in the middle of both ends of the plug, and connecting threads are provided outside the connecting tube, and an inner sleeve E24 is screwed outside the connecting tube on the side of the plug located inside the cooling tube, and the connecting tube on the side of the plug located outside the cooling tube is connected to an external water source through a pipeline, and an output hole E29 is provided on the outer wall of the cooling tube at one end of the plug, and the output hole is connected to an external water source through a pipeline, one end of the inner sleeve is connected to the connecting tube on the side of the plug located inside the cooling tube, and the other end extends to the closed end of the cooling tube, and there is a gap E24 between the end of the inner sleeve and the inner end surface of the closed end of the cooling tube. 25, that is, the water in the water source is input into the plug through the existing water pump, and then input into the inner sleeve, and then input into the cooling pipe through the inner sleeve, and then output from the output hole far away from the output end of the inner sleeve, so that the water flow can continuously take away the heat.

[0052] In this embodiment, the specific installation method of the cooling mechanism is as follows: an insertion hole E 26 is provided on the middle part of the non-roller end of the rotating shaft, and the cooling tube is rotatably connected to the insertion hole. The insertion hole can be provided in the rotating shaft section corresponding to the roller. The cooling tube and the insertion hole are rotatably connected with each other in contact, which is convenient for heat transfer. At the same time, since the roller rotates less only when the blank moves, there will not be much wear between the insertion hole and the cooling tube. At the same time, the roller and the rotating shaft can be supported by existing materials with strong thermal conductivity, and of course, they can also be supported by existing heat-resistant steel materials. A limiting circular groove E 27 is provided on the pressing swing arm on the side away from the rotating seat. The limiting circular groove is concentric with the rotating hole, and the diameter of the limiting circular groove is larger than the diameter of the rotating hole. The rotating hole is connected to the limiting circular groove. A limiting shoulder E 28 is provided on the outer side of the pipe section in the middle of the cooling tube corresponding to the limiting circular groove, that is, the plug and the output hole are not as large as those entering the insertion hole.

[0053] like Figure 1-8As shown, the blank sorting mechanism F includes a sorting mechanism F2 installed at the output end of the blank heating device F1, the sorting mechanism includes an inclined main guide groove F3, branch guide grooves F4 are symmetrically arranged on both sides of the input end of the main guide groove, and the two branch guide grooves correspond to the blanks F5 with temperatures higher than the required range and lower than the required range, respectively. The side parts of the two sides of the main guide groove are symmetrically and movably connected with swing guide mechanisms F6 for opening and closing the branch guide grooves. A temperature detection mechanism F7 is installed on the side of the output end of the blank heating device. The temperature detection mechanism can be an existing infrared sensor. When in use, the blank output by the blank heating device is detected by the temperature detection mechanism. If the temperature is within the required range, no other action is performed, and the blank falls directly from the main guide groove to the forging device. If the temperature is too high or too low, the corresponding swing guide mechanism is opened. After the blank falls into the main guide groove, it slides into the corresponding branch guide groove under the action of the corresponding swing guide mechanism to achieve sorting.

[0054] In this embodiment, openings F8 are provided at the input ends of the branch guide grooves on both sides of the input end of the main guide groove, and the swing guide mechanism includes a swing plate F9 perpendicular to the bottom plate of the main guide groove, the length of the swing plate is longer than the length of the opening, the inclined lower end of the swing plate is rotatably connected to the bottom plate of the main guide groove at the lower end of the corresponding opening, and the inclined upper end of the swing plate is abutted against the inner side wall of the main guide groove at the upper part of the corresponding opening. Specifically, a rotating shaft F10 perpendicular to the bottom plate of the main guide groove is fixed at the inclined lower end of the swing plate, and the rotating shaft penetrates the bottom plate of the main guide groove and extends downward, and a motor assembly F for driving the rotating shaft to rotate is installed under the main guide groove. 11. The temperature detection mechanism is electrically connected to the motor assembly, and the temperature detection mechanism and the motor assembly are electrically connected and controlled by an existing circuit board. Since the relevant circuit control is a prior art, no further elaboration is given. When in use, the swing plate swings under the action of the motor to open and close the opening. At the same time, the length of the swing plate should be greater than the width of the main guide groove to avoid the swing plate after swinging being unable to effectively block the main guide groove, causing unqualified blanks to fall along the main guide groove.

[0055] In this embodiment, in order to realize the falling of the blank to the subsequent forging equipment, a conveying channel F12 is connected to the output end of the main guide groove, and the conveying channel is tubular. A first open port F13 is cut and formed on the middle channel section of the conveying channel. A first deceleration mechanism F14 is mounted on the first open port, and the falling blank is decelerated by the first deceleration mechanism to avoid direct collision with the forging equipment due to the blank falling too fast. Specifically, vertical first fixed plates F15 are symmetrically welded on the left and right sides of the first open port, and the first deceleration mechanism includes a deceleration flap mechanism, and the deceleration flap mechanism includes support plates AF16 symmetrically arranged on the left and right, and the support plates A are screwed on the corresponding first fixed plates, and a flap F14 is rotatably connected between the tops of the two support plates A. 17, the lower part of the flap extends into the first open mouth and blocks the conveying channel. When the blank falls, it will knock open the flap and then fall. At the same time, due to the collision with the flap, the kinetic energy is reduced, and the speed of falling to the outlet of the conveying channel is also reduced. In order to avoid excessive flipping of the flap after being hit, the first deceleration mechanism also includes a flap limiting mechanism, and the flap limiting mechanism is located at the rear side of the deceleration flap mechanism. The flap limiting mechanism includes a support plate BF 18 symmetrically arranged on the left side, and the support plate B is screwed to the corresponding first fixed plate and at the rear side of the corresponding support plate A. A crossbeam F 19 is horizontally arranged between the tops of the two support plates B. A limiting column structure is arranged on the crossbeam corresponding to the extreme position of the flipping of the flap. The specific structure of the limiting column structure is as follows: the limiting column structure includes a limiting column F 20, and a horizontal clamping plate F 21 is arranged on the upper end of the limiting column, and the clamping plate abuts against the upper surface of the crossbeam, and a sliding hole F is arranged on the crossbeam corresponding to the limiting column. 22, the limit column is slidably connected in the sliding hole, the lower end of the limit column extends out of the sliding hole, the lower end of the limit column is screwed on the limit plate F 23, the limit column is located under the cross beam plate, and the outer shell of the column body is connected with a spring F 24, the lower end of the spring is fixed on the limit plate, and the upper end is fixed on the lower surface of the cross beam plate. Under normal circumstances, the flap and the limit column are not in contact, and then when a blank passes by, the flap is flipped due to the impact of the blank. At this time, the limit position of the flip will contact the limit column, so there will be no problem of over-flipping. Of course, the setting height of the limit column will not affect the passage of the blank.

[0056] In this embodiment, in order to achieve height adjustment of the flap limit mechanism and the deceleration flap mechanism, at least two guide holes F25 whose length direction is perpendicular to the conveying direction of the conveying channel are provided on the plate bodies of the support plates A and B, and guide bolts F26 are slidably connected in the guide holes. The threaded section of the guide bolt passes through the guide hole and is fixed on the first fixed plate. The bolt head of the guide bolt abuts against the support plate A or the side of the support plate away from the first fixed plate. When in use, the guide bolt is unscrewed, and then the support plates A and B slide to the required height, and then the guide bolt is tightened. The bolt head of the guide bolt and the first fixed plate jointly clamp the support plates A and B, so as to achieve height adjustment of the flap limit mechanism and the deceleration flap mechanism.

[0057] In this embodiment, in order to reduce the falling speed of the defective products output by the branch guide groove, a branch conveying channel F27 is connected to the output end of the branch guide groove. The branch conveying channel is tubular. At least two second open ports F28 are cut and formed on the middle channel section of the branch conveying channel. A second deceleration mechanism is mounted on the second open port. The reason for setting two second deceleration mechanisms is that since the branch conveying channel is steeper than the conveying channel, the falling speed is much greater than the falling speed in the conveying channel, so more second deceleration mechanisms need to be set for deceleration. Vertical second fixed plates F29 are symmetrically welded on the left and right sides of the second open port. The second deceleration mechanism includes a second flap mechanism. The second flap mechanism includes a support plate CF30 symmetrically arranged on the left and right. The support plate C is screwed on the corresponding second fixed plate. A counterweight flap is rotatably connected between the tops of the two support plates C. The counterweight flap includes a plate body F31. The plate body is rotatably connected between the two support plates C. A counterweight block F31 is installed on the side of the plate body away from the input end of the branch conveying channel. 32. At the same time, the support plate C and the second fixed plate can also be connected by means of guide bolts and guide holes to facilitate height adjustment. The lower part of the plate body extends into the second open mouth and blocks the branch transmission channel. The specific action is the same as the deceleration flap mechanism, so it will not be elaborated.

[0058] In this embodiment, in order to facilitate the main guide groove and the branch guide groove to be connected with the conveying channel and the branch conveying channel respectively, the output ends of the main guide groove and the branch guide groove are both provided with a narrowing F33.
