DETAILED DESCRIPTION

[0024] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0025] Example 1, reference Figure 1 , which is the first embodiment of the present invention, provides a stamping device for medical device processing, which can stamp metal sheets into corresponding medical devices as needed, and includes a stamping mechanism 100.

[0026] Specifically, the stamping mechanism 100 includes a machine table 101, a top frame 102 is fixedly installed on the outer periphery of the surface of the machine table 101, and a stamping seat 103 is installed in the middle of the surface of the machine table 101, and a stamping hole 104 for placing a plate is reserved on the top of the stamping seat 103. A cylinder 105 for stamping is also installed on the top of the top frame 102, and a top plate 106 is installed at the bottom of the cylinder 105. At the same time, a stamping head 107 that cooperates with the stamping hole 104 is also installed on the bottom surface of the top plate 106.

[0027] When in use, the metal sheet to be processed is placed on the punching port 104 , and then the cylinder 105 is started, and the punching head 107 is driven downward by the cylinder 105 , so that the sheet is punched into shape under the cooperation of the punching head 107 and the punching port 104 .

[0028] Example 2, reference Figure 1~Figure 5 , which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides an adsorption mechanism 200 for a stamping device for medical device processing, which solves the problem that the plate is easily displaced during stamping and affects the stamping quality.

[0029] Specifically, the adsorption mechanism 200 includes a ceiling member 201 disposed at the bottom of the punching port 104 , a control member 202 runs through the ceiling member 201 , an isolation member 203 is installed inside the ceiling member 201 , and a control groove 204 is provided on the inner wall of the ceiling member 201 .

[0030] Furthermore, the ceiling member 201 includes a suction cup 201a, the bottom of the suction cup 201a is connected to a connecting tube 201b, one end of the connecting tube 201b is connected to an airbag 201c, and a one-way valve 201d is installed at the bottom of the airbag 201c. Through the setting of the one-way valve 201d, external air enters the airbag 201c through the one-way valve 201d, and the gas inside the airbag 201c can only flow inside the connecting tube 201b.

[0031] The control part 202 includes a pressure rod 202a that passes through the inside of the stamping seat 103, and a sleeve 202b is arranged on the outside of the pressure rod 202a. A compensation spring 202c is arranged between the pressure rod 202a and the sleeve 202b so that relative displacement can be generated between the pressure rod 202a and the sleeve 202b, and a return spring 202d is also arranged at the bottom of the sleeve 202b. The return spring 202d can elastically support the sleeve 202b to achieve rapid resetting of the sleeve 202b. At the same time, an air port 202e connected to the connecting pipe 201b is reserved on the outer wall of the sleeve 202b.

[0032] The isolating member 203 includes a first piston 203a disposed inside the connecting tube 201b, a second piston 203b is movably mounted on one side of the first piston 203a, and the first piston 203a and the second piston 203b are both fitted with the inner wall of the connecting tube 201b, and the first piston 203a and the second piston 203b are both provided with connecting ports 203c, and the connecting ports 203c on the first piston 203a and the connecting ports 203c on the second piston 203b are staggered, so that when the two groups of connecting ports 203c are in a staggered state, the connecting tube 201b can be isolated and closed, so that when the first piston 203a and the second piston 203b are away from the suction cup 201a, the air pressure inside the suction cup 201a can be reduced, and then the purpose of adsorbing and fixing the plate can be achieved with the help of the suction cup 201a, and when the second piston 203b rotates to make the two groups of connecting ports 203c overlap, The connecting tube 201b can be opened. At this time, the air inside the airbag 201c can be discharged through the connecting tube 201b via the suction cup 201a under the action of external force. At the same time, one end of the second piston 203b is connected to a rope 203d, and the rope 203d is sleeved on the outside of the sleeve 202b. Therefore, when the sleeve 202b moves downward, the two pistons can be pulled to move inside the connecting tube 201b by the rope 203d. At the same time, a push spring 203e is also provided at one end of the second piston 203b on the same side as the rope 203d. After the sleeve 202b is reset, the two pistons can be reset with the help of the elastic force of the push spring 203e. A guide head 203f is also integrally provided on the outer wall of the second piston 203b. At the same time, a contraction spring 203g is also provided between the guide head 203f and the second piston 203b, so that the guide head 203f can perform a certain telescopic movement with the help of the elastic force of the contraction spring 203g.

[0033] The control groove 204 is opened on the inner wall of the connecting tube 201b, and the guide head 203f cooperates with the control groove 204. The control groove 204 includes a pull-out groove 204a, one end of the pull-out groove 204a is connected to the opening groove 204b, one end of the opening groove 204b is connected to the push-back groove 204c, one end of the push-back groove 204c is connected to the breaking groove 204d, and the pull-out groove 204a, the opening groove 204b, the push-back groove 204c and the breaking groove 204d are connected end to end in sequence.

[0034] Furthermore, the connection between the pull-out groove 204a and the opening groove 204b is arranged in a stepped manner, that is, the depth of the opening groove 204b is greater than that of the pull-out groove 204a, so that when the isolating member 203 is at the maximum distance from the suction cup 201a under the traction of the sleeve 202b, the guide head 203f moves from the pull-out groove 204a to the connection between the pull-out groove 204a and the opening groove 204b, so that the guide head 203f is further extended and embedded in the opening groove 204b, and at the same time, the opening groove 204b and the shut-off groove 204d are arranged in a spiral inclination along the inner wall of the connecting pipe 201b. When the two pistons are pushed by the push spring 203e, When resetting, the second piston 203b can rotate with the cooperation of the guide head 203f and the open groove 204b thereon, so that the second piston 203b can overlap and connect with the connecting port 203c on the first piston 203a, and the gas inside the airbag 201c can be discharged from the suction cup 201a through the connecting pipe 201b, and then the stamped sheet can be lifted up with the help of the gas pressure, reducing the possibility of the workpiece being stuck on the mold, making it easier for users to take out the stamped workpiece, and the flow of gas can take away part of the heat on the workpiece, accelerate the cooling speed of the workpiece, and avoid secondary deformation of the workpiece as much as possible.

[0035] At the same time, under the setting of the shut-off groove 204d, when the closing piece moves from the push-back groove 204c to the shut-off groove 204d under the push of the push spring 203e, it can rotate again under the action of the shut-off groove 204d to achieve the purpose of staggering the connecting ports 203c on the two pistons again, thereby ensuring the recycling needs of the isolation piece 203. At the same time, the connection between the shut-off groove 204d and the pull-out groove 204a is set at a slope, thereby ensuring that the guide head 203f can smoothly return to the pull-out groove 204a.

[0036] It should be noted that the elastic force of the compensation spring 202c is much greater than that of the return spring 202d. Therefore, when the sleeve 202b moves downward due to external pressure, the return spring 202d is compressed one step ahead of the compensation spring 202c, that is, the sleeve 202b and the pressure rod 202a move downward synchronously first, and after the sleeve 202b moves down to the right position, the compensation spring 202c is further compressed to compensate for the downward movement of the pressure rod 202a. By setting the elastic force of the compensation spring 202c to be greater than the elastic force of the return spring 202d, it can be achieved that when the pressure rod 202a moves downward, the sleeve 202b first controls the movement of the isolation member 203, so that the fixation of the plate is completed in the initial stage of stamping.

[0037] When in use, first place the sheet to be punched on the two suction cups 201a and press them tightly, then start the cylinder 105 for punching, and the cylinder 105 synchronously drives the top plate 106 and the punch head 107 to move downward, at this time, the top plate 106 first contacts the pressure rod 202a, prompting the pressure rod 202a and the sleeve 202b to move downward, thereby the first piston 203a and the second piston 203b can be pulled away from the suction cup 201a by the rope 203d, so as to reduce the internal air pressure of the suction cup 201a, thereby Under the action of the internal and external pressure difference, the plate is adsorbed and fixed. After the sleeve 202b moves into place, as the top plate 106 and the punch head 107 continue to move downward, the pressure rod 202a and the sleeve 202b move relative to each other until the pressure rod 202a is completely retracted into the inside of the punch seat 103. At this time, the punch head 107 cooperates with the punch port 104 to complete the punching. After the punching is completed, the cylinder 105 drives the top plate 106 and the punch head 107 to retract. At this time, the pressure rod 202a and the sleeve 202b are retracted by the compensation spring 202c and the return spring The first piston 203a and the second piston 203b are reset sequentially under the elastic force of the first piston 202d, and the first piston 203a and the second piston 203b are reset synchronously under the action of the push spring 203e. During the reset process of the two, the second piston 203b can be deflected under the cooperation of the opening groove 204b and the guide head 203f, so that the connecting port 203c on it coincides with the connecting port 203c on the first piston 203a, so that the internal gas of the airbag 201c can be discharged from the suction cup 201a through the connecting pipe 201b, so as to lift the workpiece after stamping. And dissipate heat for it, and as the two pistons continue to reset, when the guide head 203f moves to the shut-off groove 204d through the push-back groove 204c, the second piston 203b can be deflected again under the action of the shut-off groove 204d, so that the connecting ports 203c on the two pistons are staggered again, and the connecting pipe 201b is separated and closed again. At the same time, the guide head 203f returns to the starting end of the pull-out groove 204a through the shut-off groove 204d to facilitate the subsequent use of the isolation piece 203. At this time, a stamping process is completed.

[0038] In summary, through the setting of the control part 202, it can be combined with the stamping action of the stamping equipment. With the cooperation of the control groove 204, the position and use status of the isolation part 203 can be switched synchronously, so that under the setting of the ceiling part 201, the adsorption and fixation of the sheet to be stamped, and the ejection and cooling of the workpiece after stamping are achieved, thereby ensuring the stability of the workpiece during the stamping process. At the same time, the stamped sheet can be lifted up with the help of the gas pressure, reducing the possibility of the workpiece being stuck on the mold, making it convenient for the user to take out the stamped workpiece, and part of the heat on the workpiece can be taken away by the flow of gas, thereby accelerating the cooling speed of the workpiece and avoiding secondary deformation of the workpiece as much as possible. Example 3, reference Figure 1 to Figure 6, which is the third embodiment of the present invention. Different from the previous embodiment, this embodiment provides an adsorption mechanism 200 for a stamping device for processing medical devices, which solves the problem of inconvenience in controlling the inflation and deflation of the airbag 201c.

[0039] Specifically, the adsorption mechanism 200 further includes an extrusion member 205 disposed outside the control member 202 .

[0040] Furthermore, the extrusion member 205 includes a connecting gear rod 205a disposed on the top of the airbag 201c, and a transmission tooth 205b is connected to the outer side of the connecting gear rod 205a.

[0041] A plurality of teeth are arranged in a horizontal array on the outer wall of the sleeve 202b, and the teeth are meshed with the transmission teeth 205b, so that the sleeve 202b and the connecting gear rod 205a can be linked through the transmission teeth 205b. When the sleeve 202b moves downward during the stamping process, the connecting gear rod 205a can be moved upward through the transmission of the transmission teeth 205b, and then the airbag 201c is pulled up by the connecting gear rod 205a, and the gas inside the airbag 201c is replenished through the one-way valve 201d. When the sleeve 202b rises and resets, the connecting gear rod 205a moves downward, thereby squeezing the airbag 201c to discharge the air inside it, thereby meeting the user's usage needs.

[0042] In summary, by setting the extrusion member 205, it can be linked with the control member 202, so that the airbag 201c can automatically switch between inflation and deflation according to the use status of the suction cup 201a, thereby improving the linkage between the various components.

[0043] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
