Description

Technical Field

[0001] The invention belongs to the technical field of stamping and forming, in particular to a processing die for a cylinder head of an internal combustion engine. Background Art

[0002] Internal combustion engine cylinder head processing molds (processing equipment) are dedicated equipment used for cylinder head molding and precision machining. They accurately replicate the complex structure of the cylinder head (such as the combustion chamber, valve seat ring, cooling water channel, etc.) through the mold cavity. Combined with casting or machining processes (such as high-pressure casting, CNC milling, etc.), they ensure that the dimensional accuracy, form and position tolerances, and surface quality of the cylinder head meet design requirements. At the same time, they optimize the mold material and cooling system to improve production efficiency and yield rate.

[0003] In the existing technology, when the conveying mechanism delivers the cylinder head workpiece to the processing table, the workpiece detection sensor triggers the PLC control program, driving the pneumatic fingers to clamp the workpiece; then the processing table retracts to the bottom of the stamping cylinder, and the stamping cylinder piston rod extends downward, and the specific parts of the cylinder head (such as the guide seat ring hole, camshaft hole, etc.) are stamped with a preset stamping force; after the processing is completed, the stamping cylinder retracts, the processing table extends back to the initial position, the pneumatic fingers release the workpiece, and the system sends a processing completion signal to the production line.

[0004] The above scheme still has some problems in practical application. Although the existing device can complete the stamping work of the cylinder head workpiece, the existing stamping process is usually designed as a sequential operation (first loading, then stamping, and finally unloading). In the sequential operation, the loading and unloading links need to be performed in sequence and cannot be processed in parallel. As a result, after the stamping machine completes a stamping action, it must wait for the loading and unloading operations to be completed before it can proceed to the next stamping action. This waiting time will significantly increase the time of the entire stamping cycle, thereby reducing production efficiency.

[0005] To this end, the present invention provides a die for machining a cylinder head of an internal combustion engine. Summary of the Invention

[0014] Preferably, a synchronous calibration mechanism for adjustment is provided on the upper part of the intermittent feeding mechanism, and the synchronous calibration mechanism includes an electric cylinder, which is fixedly connected to the bottom of the first placement groove, and the output end of the electric cylinder is fixedly connected to the second displacement rod.

[0015] Preferably, a guide groove is provided at the bottom of the first placement groove, a guide block is slidably connected inside the guide groove, a return spring is fixedly connected to one side of the guide block, the other end of the return spring is fixedly connected to the side wall of the first placement groove, and a movable plate is fixedly connected to the top of the guide block.

The second displacement rod slides inside the guide groove through the guide block, so when the output end of the electric cylinder is extended, while synchronously driving the second displacement rod to perform linear motion, it can also push the movable plate to perform linear motion. Since there are two movable plates symmetrically arranged about the central axis of the second displacement rod, when the second displacement rod moves, it will synchronously push the two movable plates to perform relative linear motion along the inclined surface of the oblique rod of the second displacement rod, thereby ensuring that the material is always in the middle part of the second placement groove, thereby improving the more regular distribution of the material in the initial state, thereby reducing the time of subsequent calibration, and further improving the working efficiency of the equipment.

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods. Example

[0022] like Figures 1 to 8 As shown, an internal combustion engine cylinder head processing die according to an embodiment of the present invention includes a stamping device 1, the stamping device 1 includes a support frame 101, a hydraulic cylinder 102 is fixedly connected to the top of the support frame 101, an upper die 103 is fixedly connected to the output end of the hydraulic cylinder 102, and a lower die 104 is fixedly connected to the lower part of the support frame 101. An intermittent feeding mechanism 2 is provided inside the stamping device 1; The intermittent feeding mechanism 2 includes a first displacement rod 209 rotatably arranged on the side of the upper mold 103, and a support plate 211 fixedly arranged on the side of the lower mold 104. The movement of the first displacement rod 209 can lift the material placed on the upper part of the support plate 211, thereby completing uninterrupted feeding work.

[0023] Specifically, the existing stamping process is usually designed as a sequential operation (first loading, then stamping, and finally unloading). In the sequential operation, the loading and unloading steps need to be carried out in sequence and cannot be processed in parallel. As a result, after the stamping machine completes one stamping action, it must wait for the loading and unloading operations to be completed before the next stamping action can be carried out. This waiting time will significantly increase the time of the entire stamping cycle, thereby reducing production efficiency. Therefore, the present invention solves this problem by setting up a corresponding structure. In the internal combustion engine cylinder head processing mold described in the present invention, when a stamping operation is required, the plate is first placed above the lower mold 104. At this time, the hydraulic cylinder 102 fixed on the upper part of the support frame 101 is started. When the hydraulic cylinder 102 is started, its output shaft will move downward in a straight line, and in the process of movement, it drives the upper mold 103 to move downward synchronously. When the upper mold 103 and the lower mold 104 are completely fitted together on the opposite side, the stamping work of the material can be completed. However, since the existing stamping process is usually designed as a sequential operation (first loading, then stamping, and finally unloading), in the sequential operation During operation, the loading and unloading steps need to be carried out in sequence and cannot be processed in parallel, resulting in that after the stamping machine completes a stamping action, it must wait for the loading and unloading operations to be completed before it can proceed to the next stamping action. This waiting time will significantly increase the time of the entire stamping cycle, thereby reducing production efficiency. At this time, the continuous movement of the first displacement rod 209 can lift the material on the support plate 211 and the material that has been stamped on the lower mold 104 at the same time, and the loading and unloading of the material can be completed at the same time during the movement of the first displacement rod 209, thereby reducing the time for separate loading and unloading operations, and further improving the efficiency of the stamping work. Example

[0024] like Figures 2 to 8 As shown in Comparative Example 1, another embodiment of the present invention is: like Figure 3 and Figure 5 As shown, the intermittent feeding mechanism 2 in this embodiment includes a support plate 201, and the support plate 201 is fixedly connected to the upper part of the workbench where the upper mold 103 is located. The upper part of the platform where the lower mold 104 is located is fixedly connected to an output motor 202, and the output end of the output motor 202 is fixedly connected to a first work-shaped part 203.

[0025] The first I-shaped member 203 is rotatably connected to the interior of the support plate 201, and a transmission belt 204 is connected to the groove of the first I-shaped member 203; like Figure 3 As shown, the inner ring surface of the transmission belt 204 in this embodiment is rotatably connected to the second I-shaped piece 205, and the second I-shaped piece 205 is rotatably connected to the upper part of the platform where the lower mold 104 is located. The second I-shaped piece 205 and the first I-shaped piece 203 are located on the same horizontal plane.

[0026] Specifically, when it is necessary to stamp the cylinder head of the internal combustion engine, the output motor 202 fixed to the platform where the lower mold 104 is located is started. When the output motor 202 is started, the first work-shaped part 203 will be driven to rotate through its output shaft. Since the transmission belt 204 is arranged in the groove of the output motor 202 and the transmission belt 204 is in a taut state, when the first work-shaped part 203 rotates, it will drive the transmission belt 204 to transmit, and then drive the second work-shaped part 205 to rotate. When the second work-shaped part 205 rotates, it can drive some of the other mechanisms in the intermittent feeding mechanism 2 to rotate, thereby improving the stability of the device operation.

[0027] like Figure 4 and Figure 5 As shown, in this embodiment, one end of the first I-shaped member 203 is fixedly connected to a first circular plate 206 , and a fixed shaft 207 is fixedly connected to the middle of a side of the first circular plate 206 away from the first I-shaped member 203 ; One end of the fixed shaft 207 away from the first circular plate 206 is fixedly connected to the second circular plate 208 .

[0028] like Figure 5 As shown, in this embodiment, a first displacement rod 209 is fixedly connected to the side of the second circular plate 208 away from the fixed shaft 207 . A first placement groove 210 is defined on the upper portion of the first displacement rod 209 , and a second placement groove 212 is defined inside the supporting plate 211 .

[0029] Specifically, before the output motor 202 is started, the end of the first displacement rod 209 is flush with the side surface of the supporting plate 211. At this time, the output motor 202 starts to synchronously drive the first workpiece 203 to rotate, and through the first workpiece 203 drives the first circular plate 206 fixed thereto to rotate synchronously. When the first circular plate 206 rotates, it will synchronously drive the fixed shaft 207 fixed thereto to move synchronously. Since the fixed shaft 207 is fixed to the area near the outer ring surface of the second circular plate 208, when the fixed shaft 207 rotates, it will drive the second circular plate 208 to rotate around the first circular plate 2 06 rotates, and at the same time drives the first displacement rod 209 fixed to the second circular plate 208 to rotate synchronously. When the first displacement rod 209 rotates, the first placement slot 210 also rotates around the central axis of the first circular plate 206. Since the edge of the material is at the bottom of the first placement slot 210, when the first placement slot 210 moves, the material also moves synchronously. At this time, the material will be separated from the second placement slot 212 on the supporting plate 211. At this time, the first displacement rod 209 and the supporting plate 211 are staggered and on the same horizontal plane. When the fixed shaft 207 moves to the vertical state, the first displacement rod 209 also moves to the highest end. At this time, the output motor 202 continues to move and drives the fixed shaft 207 to rotate from the vertical state to the horizontal state on the other side during the movement. At the same time, the support plate 211 drives the material to move downward along the arc. When the positioning pin on the lower mold 104 is inserted into the positioning hole of the material, the support plate 211 and the first displacement rod 209 are on the same horizontal plane, but are still in a misaligned state. When the first circular plate 206 continues to rotate, the direction of the fixed shaft 207 will change from a horizontal state to a vertical downward state, and the first displacement rod 209 will be synchronously driven to move downward through the second circular plate 208. When the direction of the fixed shaft 207 changes to the initial state, the end face of the first displacement rod 209 and the side face of the supporting plate 211 will be flush again. When the upper mold 103 and the lower mold 104 complete the stamping work and lower the positioning pin, the output motor 202 will continue to start. At this time, the first placement slot 209 set in the middle of the first displacement rod 209 is 10 will move along with the movement of the first displacement rod 209, and lift the material after stamping out of the surface of the lower mold 104. When the second circular plate 208 rotates half a circle, the material placed on the loading port will be lifted by the first placement groove 210 at the feed port and placed on the lower mold 104. Through the same movement state of the first placement grooves 210 at different positions on the first displacement rod 209, uninterrupted loading and unloading can be achieved, thereby reducing the time consumed by the device in the loading and unloading process, thereby improving the efficiency of the stamping work.

[0030] like Figure 7 and Figure 8 As shown, the intermittent feeding mechanism 2 in this embodiment is provided with a synchronous calibration mechanism 3 for adjustment on the upper part, and the synchronous calibration mechanism 3 includes an electric cylinder 301, and the electric cylinder 301 is fixedly connected to the bottom of the first placement groove 210, and the output end of the electric cylinder 301 is fixedly connected to the second displacement rod 302.

[0031] like Figure 7 and Figure 8 As shown, in this embodiment, a guide groove 306 is provided at the bottom of the first placement groove 210, and a guide block 304 is slidably connected inside the guide groove 306. A return spring 305 is fixedly connected to one side of the guide block 304, and the other end of the return spring 305 is fixedly connected to the side wall of the first placement groove 210. A movable plate 303 is fixedly connected to the top of the guide block 304.

[0032] Specifically, when the material is placed on the supporting plate 211 in front of the lower mold 104, the electric cylinder 301 on the area of ​​the first displacement rod 209 will be activated. At this time, the output end of the electric cylinder 301 will extend, and at the same time, it will drive the second displacement rod 302 fixed to its output end to move synchronously. The second displacement rod 302 is composed of two oblique rods and a rectangular rod, and the oblique rod in the second displacement rod 302 is adapted to the end face of the moving plate 303, so when the second displacement rod 302 moves, it will synchronously drive the moving plate 303 to move, but because the oblique rod gradually becomes thinner from the end face of the rectangular rod away from the second displacement rod 302 to the connection with the end face of the rectangular rod, and the second displacement rod 302 is through The guide block 304 slides inside the guide groove 306, so when the output end of the electric cylinder 301 is extended, it can simultaneously drive the second displacement rod 302 to perform a linear motion while also pushing the movable plate 303 to perform a linear motion. Since there are two movable plates 303 symmetrically about the central axis of the second displacement rod 302, when the second displacement rod 302 moves, it will synchronously push the two movable plates 303 to perform relative linear motion along the inclined surface of the oblique rod of the second displacement rod 302, thereby ensuring that the material is always in the middle part of the second placement groove 212, thereby improving the more regular distribution of the material in the initial state, thereby reducing the time for subsequent calibration, and further improving the working efficiency of the equipment.

[0033] Working principle: when it is necessary to stamp the cylinder head of the internal combustion engine, start the output motor 202 fixed on the platform where the lower mold 104 is located. When the output motor 202 is started, it will drive the first work-shaped part 203 to rotate through its output shaft. Since the transmission belt 204 is set in the groove of the output motor 202 and the transmission belt 204 is in a taut state, when the first work-shaped part 203 rotates, it will drive the transmission belt 204 to transmit, and then drive the second work-shaped part 205 to rotate. When the second work-shaped part 205 rotates, it can drive some of the mechanisms in the remaining intermittent feeding mechanism 2 to rotate, thereby improving the stability of the device operation.

[0034] Before the output motor 202 is started, the end of the first displacement rod 209 is flush with the side surface of the supporting plate 211. At this time, the output motor 202 starts to synchronously drive the first workpiece 203 to rotate, and through the first workpiece 203, it drives the first circular plate 206 fixed thereto to rotate synchronously. When the first circular plate 206 rotates, it synchronously drives the fixed shaft 207 fixed thereto to move synchronously. Since the fixed shaft 207 is fixed to the area near the outer ring surface of the second circular plate 208, when the fixed shaft 207 rotates, it drives the second circular plate 208 to revolve around the first circular plate 206. The first displacement rod 209 fixed to the second circular plate 208 rotates along its central axis, and at the same time drives the first displacement rod 209 fixed to the second circular plate 208 to rotate synchronously. When the first displacement rod 209 rotates, the first placement slot 210 also rotates around the central axis of the first circular plate 206. Since the edge of the material is at the bottom of the first placement slot 210, when the first placement slot 210 moves, the material also moves synchronously. At this time, the material will be separated from the second placement slot 212 on the supporting plate 211. At this time, the first displacement rod 209 and the supporting plate 211 are staggered and distributed on the same horizontal plane. When the fixed shaft 207 moves to the vertical state, the first displacement rod 209 also moves to the highest end. At this time, the output motor 202 continues to move and drives the fixed shaft 207 to rotate from the vertical state to the horizontal state on the other side during the movement. At the same time, the support plate 211 drives the material to move downward along the arc. When the positioning pin on the lower mold 104 is inserted into the positioning hole of the material, the support plate 211 and the first displacement rod 209 are on the same horizontal plane, but are still in a misaligned state. When the first circular plate 206 continues to rotate, the direction of the fixed shaft 207 will change from a horizontal state to a vertical downward state, and the first displacement rod 209 will be synchronously driven to move downward through the second circular plate 208. When the direction of the fixed shaft 207 changes to the initial state, the end face of the first displacement rod 209 and the side face of the supporting plate 211 will be flush again. When the upper mold 103 and the lower mold 104 complete the stamping work and lower the positioning pin, the output motor 202 will continue to start. At this time, the first placement slot 209 set in the middle of the first displacement rod 209 is 10 will move along with the movement of the first displacement rod 209, and lift the material after stamping out of the surface of the lower mold 104. When the second circular plate 208 rotates half a circle, the material placed on the loading port will be lifted by the first placement groove 210 at the feed port and placed on the lower mold 104. Through the same movement state of the first placement grooves 210 at different positions on the first displacement rod 209, uninterrupted loading and unloading can be achieved, thereby reducing the time consumed by the device in the loading and unloading process, thereby improving the efficiency of the stamping work.

[0035] When the material is placed on the supporting plate 211 in front of the lower mold 104, the electric cylinder 301 on the area of ​​the first displacement rod 209 will be started. At this time, the output end of the electric cylinder 301 will extend, and at the same time, it will drive the second displacement rod 302 fixed to its output end to move synchronously. The second displacement rod 302 is composed of two oblique rods and a rectangular rod, and the oblique rod in the second displacement rod 302 is adapted to the end face of the moving plate 303, so when the second displacement rod 302 moves, it will synchronously drive the moving plate 303 to move. However, since the oblique rod gradually becomes thinner from the end face of the rectangular rod away from the second displacement rod 302 to the connection with the end face of the rectangular rod, and the second displacement rod 302 is guided by the guide rod The block 304 slides inside the guide groove 306, so when the output end of the electric cylinder 301 is extended, it can simultaneously drive the second displacement rod 302 to perform a linear motion while also pushing the moving plate 303 to perform a linear motion. Since there are two moving plates 303 symmetrically arranged about the central axis of the second displacement rod 302, when the second displacement rod 302 moves, it will synchronously push the two moving plates 303 to perform relative linear motion along the inclined surface of the oblique rod of the second displacement rod 302, thereby ensuring that the material is always in the middle part of the second placement groove 212, thereby improving the more regular distribution of the material in the initial state, thereby reducing the time for subsequent calibration, and further improving the working efficiency of the equipment.
