For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] For the purpose of simplicity and illustration, the principles of the embodiments are mainly described by reference to examples. In the following description, many specific details are proposed to provide a thorough understanding of the embodiments. However, it is obvious that for those of ordinary skill in the art, these embodiments may not be limited to these specific details in practice. In some instances, known methods and structures are not described in detail to avoid making these embodiments unnecessarily difficult to understand. In addition, all embodiments can be used in combination with each other.

[0024] For example, see Figures 1 to 8 The present invention provides a technical solution: a high-speed press for metal material processing, comprising a base 1, a material changing device 2 and a controller 15, a top frame 17 is arranged above the base 1, and an extrusion push rod 16 is fixedly installed on the top frame 17, the output end of the extrusion push rod 16 drives a sliding frame 19, and the bottom of the sliding frame 19 is installed with an upper die seat 20 for extruding a workpiece 21 to be processed into a formed workpiece 7, at least one pair of guide support columns 18 are arranged between the base 1 and the top frame 17, and the sliding frame 19 is slidably installed on the guide support column 18. Towards the support column 18, a lower die seat 10 corresponding to the upper die seat 20 is fixedly mounted on the base 1, and a discharge conveyor belt 8 corresponding to the lower die seat 10 for discharging the formed workpiece 7 and a loading conveyor belt 11 for supplying the workpiece 21 to be processed are respectively provided at the left and right ends of the base 1. After the workpiece 21 to be processed delivered by the loading conveyor belt 11 enters the lower die seat 10, the extrusion push rod 16 will push the upper die seat 20 downward to extrude the workpiece 21 to be processed, so that the workpiece 21 to be processed is extruded in the lower die seat 10 to become a formed workpiece 7.

[0025] See also Figure 1 and Figure 8The material changing device 2 includes a bottom connecting frame 204 fixedly mounted on the base 1, and a screw motor 201 is fixedly mounted on the bottom connecting frame 204, and the screw motor 201 is used to drive the sliding seat 203 to move along the left and right directions through the screw, a clamping push rod 205 is fixedly mounted on the sliding seat 203, and a pushing plate 206 for clamping the workpiece 21 to be processed and the formed workpiece 7 is fixedly mounted on the clamping push rod 205, a lifting device 4 for ejecting the formed workpiece 7 out of the lower die base 10 is provided on the lower die base 10, and a pushing device 5 for pushing the lifting device 4 to move is provided on the sliding frame 19.

[0026] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6The lifting device 4 includes a lifting plate 401 arranged at the bottom of the lower die base 10 to lift the bottom of the formed workpiece 7, and a lifting rod 403 is fixedly installed at the bottom of the lifting plate 401, the lifting rod 403 and the lower die base 10 are connected by a reset spring 402, and a guide rod 404 slidably installed with the lower die base 10 is fixedly installed at the bottom of the lifting plate 401, and the pushing device 5 includes a positioning seat 502 fixedly installed on the sliding frame 19, and a pushing frame 505 for pushing the lifting rod 403 is fixedly installed on the positioning seat 502, and at least four positioning holes 501 are arranged on the top of the pushing frame 505 in a linear array, and a positioning screw is screwed on the positioning seat 502 to be plugged and fixed with the positioning hole 501 so as to adjust the installation height of the pushing frame 505 Button 503, since different types of workpieces 21 to be processed may require different lower die seats 10, in order to match the different internal depths of the lower die seats 10 to ensure that the corresponding lifting plate 401 can push the formed workpiece 7 out of the lower die seat 10, the installation height of the pushing frame 505 relative to the sliding frame 19 can be adjusted by positioning the screw button 503. In addition, different types of lower die seats 10 will have corresponding types of lifting devices 4, so as to achieve better adaptation of the lifting device 4 and the lower die seat 10. When the workpiece 21 to be processed is squeezed into the formed workpiece 7 by the upper die seat 20, the upper die seat 20 will move upward again under the drive of the extrusion push rod 16. At this time, the pushing frame 505 will also move upward under the drive of the sliding frame 19, thereby utilizing the pushing frame 50 5 pushes the lifting rod 403 upward, and then uses the lifting rod 403 to lift the lifting plate 401 upward. At this time, the lifting plate 401 can lift the molded workpiece 7 located in the lower die seat 10 upward to a preset position, and then the clamping push rod 205 begins to press the pushing plate 206 inward, so that the pushing plate 206 simultaneously clamps the molded workpiece 7 located on the lifting plate 401 and the workpiece to be processed 21 located on the feeding conveyor belt 11, and then the screw motor 201 drives the molded workpiece 7 to be transported to the discharge conveyor belt 8, and at the same time, the workpiece to be processed 21 clamped by the pushing plate 206 will also accurately enter the upper part of the lower die seat 10, and at this time, the clamping push rod 205 stops clamping, and the molded workpiece 7 falls onto the discharge conveyor belt 8 and is sent out, and the workpiece to be processed 21 clamped by the pushing plate 206 is pushed out. The workpiece 21 to be processed clamped by the plate 206 falls into the lower die base 10, and then the upper die base 20 is pushed by the extrusion push rod 16 to squeeze the workpiece 21 to be processed in the lower die base 10 downward again. In the process of the lower die base 10 falling, the pushing frame 505 will also descend, thereby losing the lifting effect on the lifting plate 401. At this time, the lifting plate 401 will fall to the bottom of the lower die base 10 under the push of the return spring 402 to avoid interfering with the extrusion process of the workpiece 21 to be processed. At the same time, the pushing plate 206 will also return to the initial position driven by the screw motor 201 to wait for the next clamping operation. In this way, the loading of the workpiece 21 to be processed and the discharge of the formed workpiece 7 can be automatically completed, so that there is no need for manual loading and unloading during the entire processing process.It can effectively improve the working efficiency of high-speed presses and avoid accidents.

[0027] See also Figure 4 and Figure 7 The base 1 is provided with a positioning device 6 for limiting the position of the workpiece 21 to be processed at a position corresponding to the feeding conveyor belt 11, and the positioning device 6 includes a lifting push rod 603 fixedly installed with the base 1, and the output end of the lifting push rod 603 drives a limiting plate 601 for limiting the position of the workpiece 21 to be processed, and a travel switch 602 for detecting whether the workpiece 21 to be processed is moved into place is fixedly installed on the limiting plate 601, and the lifting push rod 603 and the travel switch 602 are respectively electrically connected to the controller 15, and the feeding conveyor belt 11 is connected to the base 1. The docking fixing seat 14 is fixedly installed with the base 1, and the docking fixing seat 14 is provided with a support plate 13 for supporting the workpiece 21 to be processed at the position corresponding to the limit plate 601 and the feeding conveyor belt 11. The feeding conveyor belt 11 is fixedly installed with a guide plate 12 for guiding the movement direction of the workpiece 21 to be processed. When the high-speed press is not working, the lifting push rod 603 will push the limit plate 601 to the corresponding position, and then the feeding conveyor belt 11 pushes the material to the position in contact with the limit plate 601. When the travel switch 602 is triggered, the feeding conveyor belt 11 stops feeding, and the controller 15 controls the high-speed press to continue the extrusion molding operation. When the travel switch 602 is not triggered, the feeding conveyor belt 11 will continue to transport the material, and the high-speed press will delay the next round of extrusion operation. When the travel switch 602 is not triggered within the specified time interval, the controller 15 can determine that the equipment has a fault. At this time, the controller 15 sends an alarm signal through the alarm electrically connected to the controller 15, and the controller 15 The force machine is adjusted to the waiting working state until the fault is contacted. When the travel switch 602 is triggered and the material changing device 2 receives the feeding signal, the lifting push rod 603 will drive the limit plate 601 to drop to the non-working position, and then the material changing device 2 clamps the workpiece 21 to be processed and feeds it into the lower die base 10. After the material changing device 2 completes the loading, the limit plate 601 rises to the limit position again, and then the loading conveyor belt 11 continues to feed the workpiece 21 to be processed to the position where it is in contact with the limit plate 601 and can trigger the travel switch 602.

[0028] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 7 and Figure 8 The controller 15 is fixedly mounted on the top frame 17 , and the controller 15 is electrically connected to the discharge conveyor belt 8 , the loading conveyor belt 11 , the extrusion push rod 16 , the clamping push rod 205 and the screw motor 201 , respectively.

[0029] The high-speed press designed by the present invention can use the extrusion push rod 16 to drive the upper die seat 20 to complete the high-speed extrusion of the workpiece 21 to be processed, and then use the cooperation of the jacking device 4 and the pushing device 5 to push the molded workpiece 7 out of the lower die seat 10, and then realize the automatic loading of the workpiece 21 to be processed and the automatic discharge of the molded workpiece 7 through the cooperation of the feeding conveyor belt 11 and the material changing device 2, so that the loading and unloading process can be completed quickly, and the working efficiency of the equipment is effectively improved. In addition, the entire material changing process does not require manual participation, which can effectively avoid personal injury to personnel, so it is safer to use. The problem that the existing high-speed press cannot automatically load and unload at the same time is solved, and the working efficiency of the high-speed press can be effectively improved.

[0030] For example 2, please refer to Figure 8 On the basis of the first embodiment, a second clamping head 207 for clamping the formed workpiece 7 is fixedly installed on the left side of the push plate 206, and a first clamping head 202 for clamping the workpiece 21 to be processed is fixedly installed on the right side of the push plate 206. Since the size of the workpiece 21 to be processed and the size of the formed workpiece 7 before and after the extrusion process are not necessarily the same, by using a suitable first clamping head 202 and a second clamping head 207, it is possible to better adapt to the corresponding workpiece 21 to be processed and the formed workpiece 7. This method can achieve a better clamping effect, further solving the problem that the existing high-speed press cannot automatically load and unload at the same time, and can effectively improve the working efficiency of the high-speed press.

[0031] For example 3, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5On the basis of the second embodiment, a limiting device 3 for limiting the lifting position of the formed workpiece 7 is provided on the base 1, and the limiting device 3 includes a rotating seat 307 fixed to the base 1, and a rotating shaft 305 is rotatably installed on the rotating seat 307, a gear ring 304 is fixedly installed on the rotating shaft 305, and a rack 504 meshingly connected with the gear ring 304 is fixedly installed on the pushing frame 505, and an anti-dropping limiting block 301 for limiting the lifting height of the formed workpiece 7 is fixedly installed on the gear ring 304, and a lifting and lowering device 301 for inserting the base 1 is provided at the bottom of the rotating seat 307. The base 308 is provided with a height adjustment screw 9 which is screwed on the base 1 and used for pressing the lifting base 308 and adjusting the installation height of the lifting base 308. A position switch 306 which is used for detecting whether the anti-slip limit block 301 is rotated into position is fixedly installed between the gear ring 304 and the rotating base 307, and the position switch 306 is electrically connected to the controller 15. A connecting base 303 is fixedly installed on the gear ring 304, and a pitch adjustment screw 302 is rotatably installed on the anti-slip limit block 301. The pitch adjustment screw 302 is screwed on the connecting base 303 and used for adjusting the anti-slip limit block. The installation position of the anti-slip limit block 301 can be adjusted by adjusting the height adjustment screw button 9 and the distance adjustment screw button 302 for different models of the lower mold base 10, so as to achieve the correct limit of the formed workpiece 7. The anti-slip limit block 301 can adopt an L-shaped cross-section, so as to limit the height and front and rear position of the formed workpiece 7. Since the lifting plate 401 lifts upward at a fast speed, when the lifting plate 401 stops moving, the formed workpiece 7 will also move upward under the action of inertia, and the setting of the anti-slip limit block 301 can effectively prevent the molded workpiece 7 from moving upward. The formed workpiece 7 is prevented from being disengaged from the position where it can be clamped by the push plate 206, thereby ensuring that the formed workpiece 7 can be correctly clamped by the material changing device 2 and fed onto the discharge conveyor belt 8. Because of the limit device 3, the lifting plate 401 can lift the formed workpiece 7 out of the lower die base 10 at a higher speed, which can increase the working time of the high-speed press and improve the working efficiency, further solving the problem that the existing high-speed press cannot automatically load and unload at the same time, and can effectively improve the working efficiency of the high-speed press.

[0032] Embodiment 4: Based on Embodiment 3, the present invention further provides a method for using a high-speed press for metal material processing, comprising the following steps: Step 1: When the workpiece 21 to be processed needs to be processed, firstly install the lower die base 10 and the upper die base 20 of the corresponding model on the base 1 and the sliding frame 19, and adjust the position of the pushing device 5 and the limiting device 3 accordingly, and then correctly place the workpiece 21 to be processed on the feeding conveyor belt 11; Step 2: The operation process is opened through the controller 15, and then the material changing device 2 places the workpiece 21 to be processed into the lower die base 10, and then the extrusion push rod 16 drives the upper die base 20 to start extruding the upper die base 20 located in the lower die base 10 into a formed workpiece 7; Step 3: After the extrusion process is completed, the upper die base 20 rises again, and at the same time, the pushing device 5 pushes the lifting device 4 to push the formed workpiece 7 out of the lower die base 10, and then the material changing device 2 clamps the formed workpiece 7 and sends it to the discharge conveyor 8 for discharge. At the same time, the material changing device 2 will also simultaneously send the workpiece 21 to be processed on the support plate 13 into the lower die base 10 to complete the loading operation.
