Description

Technical Field

[0001] The present invention relates to the technical field of valve body production equipment, in particular to a valve body stamping forming device. Background Art

[0002] As one of the components of the valve, the valve body is mainly used to control the flow direction, pressure and flow of the fluid. As the outer shell of the valve, it often needs to withstand a large medium pressure. The main components of the valve body include the valve cover, valve core, valve seat, and valve stem. During the production process of such parts, a stamping forming device is often used to directly stamp the metal blocks in the module.

[0003] When some existing stamping forming devices are used to produce valve body parts, the upper and lower molds required for the production of parts are only composed of a single set. A metal block is placed in the lower mold, and the upper mold is pushed to fit the lower mold through the hydraulic push rod in the stamping forming device to stamp the metal block. After stamping, the formed parts are taken out and the metal block is put back to continue production. In order to speed up production efficiency, this production method often requires workers to stay focused for a long time to avoid being pinched by the upper and lower molds during the process of placing the metal block, which poses a safety hazard.

Two vertical plates for fixing the position of the guide plate are provided between the guide plate and the bottom plate. A material placing assembly for adding a release agent to the lower mold is installed on the top of the guide plate.

[0011] The material placing assembly includes a mounting column fixedly mounted on the top end of the guide plate, a toothed disc capable of vibrating being movably sleeved on the outer wall of the mounting column, a toothed plate meshing with the toothed disc being fixedly mounted on the side wall of the lower mold, a vertical column mounted on the mounting column, a liquid reservoir for storing a release agent mounted on the vertical column, an L-shaped liquid outlet plate provided on the liquid reservoir, a plurality of liquid outlet holes provided on the L-shaped liquid outlet plate for discharging the release agent in the liquid reservoir, and a plurality of return springs connecting the L-shaped liquid outlet plate to the side wall of the front end surface of the liquid reservoir.

[0013] A limiting plate for limiting the movable space of the translation block in the translation slot is fixedly installed in each of the translation slots, and the limiting plate is located above the connecting spring.

[0014] The guide assembly includes a disc fixedly mounted on the bottom end of the rotating disc, a lifting rod fixedly mounted on the bottom end of the disc, a connecting seat movably sleeved on the outer wall of the lifting rod, and a rotating wheel rotatably mounted on the bottom end of the connecting seat.

[0015] The top end of the bottom plate is provided with a circular sliding groove adapted to the rotating wheel.

[0016] The die assembly includes a fixed frame fixedly installed on the top of the base plate, and the fixed frame is composed of a cover plate and four support plates. A hydraulic push rod is installed at the bottom end of the cover plate of one of the components of the fixed frame, and the bottom of the output end of the hydraulic push rod is connected to an upper mold for stamping the valve body.

[0023] The translation block outside the translation slot contacts the inclined surface of the guide plate during the rotation of the rotating disk, and gradually enters the translation slot and clings to the guide plate under the guidance of the synchronous movement of the T-plate. At this time, the lower mold with the metal block located on the top of the translation block will move to just below the upper mold. At this time, the position of the translation block is fixed by cooperating with the guide plate and the limit plate that are close to the rotating disk, which facilitates the use of the upper and lower molds.

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] See also Figures 1 to 10 The present invention provides a technical solution: a valve body stamping forming device, comprising a base plate 1 and a die assembly located on the base plate 1, the die assembly comprising a fixed frame 2 fixedly installed on the top of the base plate 1, the fixed frame 2 is composed of a cover plate and four support plates, the cover plate and the base plate 1 are connected as a whole through the four support plates, so that the base plate 1 and the die assembly can be firmly connected as a whole, a hydraulic push rod 3 is installed at the bottom end of the cover plate, which is one of the components of the fixed frame 2, the hydraulic push rod 3 adopts the DTZ300 parallel electro-hydraulic push rod in the prior art, and the bottom of the output end of the hydraulic push rod 3 is connected to an upper mold 4 for stamping the valve body.

[0037] A stamping assembly 5 for conveniently taking the stamped valve body is provided at the top center position of the bottom plate 1. The stamping assembly 5 is placed between the four support plates. The stamping assembly 5 includes a rotating motor 6. The rotating motor 6 adopts a servo motor, and the actual position is monitored by installing a position feedback device (such as a rotary transformer, a photoelectric sensor) on the servo motor. When the rotating motor 6 drives the lower mold 13 to rotate to the bottom of the upper mold 4, the servo driver on the servo motor adjusts the current to stop the motor. This is a relatively common existing technology and is not described in detail here. A rotating disk 7 capable of replacing the position of the lower mold 13 is fixedly installed on the top of the output shaft of the rotating motor 6. Several stamping material holding assemblies for adjusting the position of the valve body after stamping are provided on the top of the rotating disk 7. The stamping material holding assembly includes several translation slots 8 provided on the top of the rotating disk 7. Translation blocks 11 are slidably installed in the translation slots 8. The bottom inner wall of the translation slot 8 is provided with a T-slot for preventing the translation block 11 from detaching from the translation slot 8. T-plates 10 are slidably installed in the T-slots. The tops of the T-plates 10 are fixedly connected to the translation blocks 11 just above them. The length of the T-plates 10 is twice the length of the translation blocks 11, and the thrust generated by the connecting springs 12 is not enough to push the T-plates 10 out of the T-slots completely. The tops of the translation blocks 11 are fixedly connected to the lower molds 13 used in conjunction with the upper mold 4, and the translation blocks 11 are connected to the inner walls of the translation slots 8 by a number of connecting springs 12 for use in conjunction with the upper mold 4. After the lower mold 13 is closed to complete the stamping of the valve body, the translation block 11 is pushed to move by the connecting spring 12, so that the lower mold 13 is moved out of the translation groove 8. At this time, the part of the top of the T-plate 10 that is not connected to the translation block 11 is still in the T-slot, to avoid the lack of horizontal restriction of the translation block 11 in the translation groove 8, resulting in the lower mold 13 falling directly downward when sliding out of the translation groove 8, and unable to return to the translation groove 8 independently after the staff takes out the valve body in the lower mold 13.

[0038] A limit plate 9 is fixedly installed in the translation groove 8 for limiting the movable space of the translation block 11 in the translation groove 8. The limit plate 9 is located above the connecting spring 12 to prevent the limit plate 9 from being on the movable path of the connecting spring 12, affecting the contraction or expansion of the connecting spring 12. After the translation block 11 is received into the translation groove 8 and is close to the limit plate 9, the lower mold 13 at the top of the translation block 11 can be rotated to the bottom of the upper mold 4 for use through the rotation of the rotating motor 6. When the upper mold 4 and the lower mold 13 are stamping the valve body, the limit plate 9 can prevent the translation block 11 and the lower mold 13 from being offset.

[0039] The bottom end of the rotating disk 7 is fixedly installed with several guide assemblies for ensuring that the rotating disk 7 can rotate smoothly following the rotating motor 6. The guide assemblies are all vertically installed at the bottom end of the rotating disk 7. The guide assembly includes a disc 15 fixedly installed at the bottom end of the rotating disk 7. A lifting rod 16 is fixedly installed at the bottom end of the disc 15. A connecting seat 17 is movably sleeved on the outer wall of the lifting rod 16. There is a hollow cavity in the connecting seat 17. The bottom inner wall of the hollow cavity is connected to the bottom side wall of the lifting rod 16 by a spring to prevent the lifting rod 16 from easily detaching from the connecting seat 17. A runner 18 is rotatably installed at the bottom end of the connecting seat 17. A circular groove adapted to the rotating wheel 18 is provided at the top of the plate 1. After the upper mold 4 is pushed by the hydraulic push rod 3 for a long time to perform stamping with the lower mold 13, it is easy to cause the rotating disk 7 to be locally overstressed and deformed. At this time, the deformed rotating disk 7 will cause the rotating wheel 18 vertically installed in one of the components of the guide assembly to be unable to continue to rotate smoothly in the circular groove following the rotating disk 7. During the rotation of the rotating disk 7, there will be a setback, prompting the staff to repair the rotating disk 7 to avoid the continued use of the deformed rotating disk 7, which will lead to a decrease in the yield of the valve body produced by the upper mold 4 and the lower mold 13 in the later stage.

[0040] When the upper die 13 is pressed against the lower die 13, the upper die 13 is pressed against the lower die 13, and the lower die 13 is pressed against the lower die 13.

[0041] A support assembly 19 is movably fitted on the side wall of the rotating disk 7 for guiding the translation block 11 to be received into the translation groove 8. The support assembly 19 includes a guide plate 20 movably fitted on the outer wall of the rotating disk 7, and the guide plate 20 is fitted on one side wall of the rotating disk 7 and is provided with two inclined surfaces for guiding the movement of the translation block 11. When the rotating motor 6 drives the rotating disk 7 to rotate clockwise, the translation block 11 outside the translation groove 8 will contact the inclined surface on the guide plate 20, and gradually enter the translation groove 8 and cling to the guide plate 20 under the guidance of the synchronous movement of the T-plate 10. At this time, the lower mold 13 containing the metal block at the top of the translation block 11 will move to the bottom of the upper mold 4. At this time, by clinging to the rotating disk The guide plate 20 of 7 cooperates with the limit plate 9 to fix the position of the translation block 11 to prevent it from moving during the valve body stamping production process. After the stamping is completed, the valve body will continue to rotate as the rotary disk 7 continues to rotate. The translation block 11 is pushed by the connecting spring 12 to contact the other inclined surface of the guide plate 20, and the translation block 11 is guided to disengage from the translation groove 8 through the push of the connecting spring 12. The side wall of the guide plate 20 on the side in contact with the rotary disk 7 is provided with an arc surface adapted to the rotary disk 7. When the rotary disk 7 is deformed, the deformed part will push the guide plate 20 to move, which is convenient for the staff to quickly observe whether the rotary disk 7 is deformed during long-term stamping use.

[0042] Two vertical plates 21 for fixing the position of the guide plate 20 are provided between the guide plate 20 and the base plate 1. Two insertion slots with the same length and width as the vertical plates 21 are provided at the bottom end of the guide plate 20 and the top end of the base plate 1. When it is necessary to detect whether the rotating disk 7 is deformed in the later stage, the vertical plates 21 can be removed to observe whether the guide plate 20 is in a stationary state during the rotation of the rotating disk 7, so as to detect whether the rotating disk 7 is deformed. When it is not necessary to detect whether the rotating disk 7 is deformed, the position of the guide plate 20 needs to be fixed by inserting the upper and lower ends of the vertical plates 21 into the insertion slots on the guide plate 20 and the base plate 1.

[0043] The top of the guide plate 20 is provided with a feeding assembly 22 for adding a release agent to the lower mold 13. The feeding assembly 22 includes a mounting post 25 fixedly mounted on the top of the guide plate 20. The outer wall of the mounting post 25 is provided with an inner concave shape, and a toothed disc 26 is provided in the inner concave shape, and the toothed disc 26 is movably mounted on the outer wall of the mounting post 25. A toothed plate 14 is fixedly mounted on the side wall of the lower mold 13 and is meshed with the toothed disc 26. The top of the toothed disc 26 is provided with a toggle steel bar, and a vibration steel bar identical to the toggle steel bar is provided on the side wall of the inner concave shape on the outer wall of the mounting post 25, and the vibration steel bar is in the toggle position. On the moving path of the moving steel bar, in the process of rotating the rotating disk 7 driven by the rotating motor 6, the tooth plate 14 will move synchronously, and the tooth plate 14 will contact the tooth plate 26 during the movement, causing the tooth plate 26 to rotate synchronously. During the rotation process, the top of the tooth plate 26 will move the steel bar and hit the vibrating steel bar, causing the vibrating steel bar to vibrate, and then drive the mounting column 25, the column 27, and the liquid storage tank 28 to vibrate slightly synchronously, causing the release agent in the liquid outlet 30 to fall downward into the lower mold 13, so that there is always release agent on the inner wall of the lower mold 13, which is convenient for the staff to take the valve body after stamping.

[0044] The top of the mounting post 25 is provided with a groove, in which a column 27 is fixedly installed, and a liquid reservoir 28 is fixedly installed on the outer wall of the column 27. The liquid reservoir 28 can store a demoulding agent for convenient demoulding. The liquid reservoir 28 is higher than the lower mold 13, which is convenient for guiding the demoulding agent in the liquid reservoir 28 into the lower mold 13. An opening is provided on the side wall of the front end surface of the liquid reservoir 28, and an L-shaped liquid outlet plate 29 is installed in the opening. The L-shaped liquid outlet plate 29 is provided with a plurality of liquid outlet holes 30 for discharging the demoulding agent in the liquid reservoir 28. The diameter of the liquid outlet hole 30 is smaller than the thickness of the side wall of the front end surface of the liquid reservoir 28, so that the liquid outlet hole 30 can be hidden in the liquid reservoir 28. Hidden grooves are provided on the inner walls of the openings on the side walls of the end faces, and rubber rings are installed in the hidden grooves. The short head of the L-shaped liquid outlet plate 29 is facing upward, and the L-shaped liquid outlet plate 29 is connected to the side walls of the front end face of the liquid storage tank 28 by a number of return springs 31, so that after the L-shaped liquid outlet plate 29 is pulled out until the liquid outlet hole 30 is exposed to the outside to discharge the release agent, the return spring 31 contracts so that the liquid outlet hole 30 can be re-entered into the liquid storage tank 28. The bottom end of the L-shaped liquid outlet plate 29 is fixedly installed with a toggle plate 32 that can be toggled by the lower mold 13 during the movement process. The toggle plate 32 is made of a rubber plate to prevent the toggle plate 32 from being unable to deform, causing the toggle plate 32 to affect the movement of the lower mold 13.

[0045] A boss 33 is fixedly installed at the center position of the top of the rotating disk 7, and several positioning plates 34 are fixedly installed on the outer wall of the boss 33. When the lower mold 13 is directly below the upper mold 4, the positioning plate 34 can fit the lower mold 13, avoiding relying solely on the limit plate 9 and the guide plate 20 to limit the movement of the translation block 11 and the lower mold 13.

[0046] A reinforcement plate 35 is fixedly installed on the top of the base plate 1, and the top of the reinforcement plate 35 is movably fitted to the rotating disk 7. During the stamping process of the valve body, the reinforcement plate 35 provides support and reinforcement for the rotating disk 7, which can avoid deformation caused by lack of support at the bottom of the rotating disk 7 during high-frequency stamping.

[0047] A sliding groove is provided at the top of the base plate 1, and a slider is slidably installed in the sliding groove. A spring is connected between the slider and the inner wall of the sliding groove, and a support block 24 capable of lifting the rotating disk 7 is fixedly installed on the top of the slider. The top of the support block 24 movably fits the bottom end of the disc 15 and is not in the area where the lifting rod 16 rotates following the rotating disk 7. The support block 24 and the disc 15 cooperate to provide support for the rotating disk 7, and cooperate with the reinforcement plate 35 to firmly support the rotating disk 7. An L-shaped connecting plate 23 is fixedly installed on the top of the support block 24, and an opening that can be inserted into a whole with the L-shaped connecting plate 23 is provided on the guide plate 20, so that after the vertical plate 21 is removed from the guide plate 20, the guide plate 20 is supported by the L-shaped connecting plate 23 and the support block 24.

[0048] When the present invention is in use, the rotary motor 6 is first controlled to rotate one circle so that the release agent in the liquid storage tank 28 is introduced into the lower mold 13, and the metal block is placed in the lower mold 13. The rotary motor 6 is started by an external power supply. The rotary motor 6 rotates to move the lower mold 13 containing the metal block to just below the upper mold 4. At this time, the hydraulic push rod 3 is controlled to move downward so that the upper mold 4 and the lower mold 13 cooperate to punch the metal block into a valve body. After the stamping is completed, the hydraulic push rod 3 is reset. At this time, the rotary motor 6 continues to rotate. During the rotation of the lower mold 13, the translation block 11 is affected by the thrust of the connecting spring 12 to slide outward of the translation groove 8 and move close to the surface of the guide plate 20. When the connecting spring 12 extends to the maximum distance, the lower mold 13 containing the valve body has moved out from just above the rotating disk 7. At this time, the other lower mold 13 is stamping the valve body. The staff can use this idle time to remove the valve body from the lower mold 13 and place the upper metal block to wait for the next stamping.

[0049] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
