Description

Technical Field

[0001] The invention relates to the technical field of welding equipment for producing vascular clamps, in particular to a welding device for producing vascular clamps. Background Art

[0002] Brazing is a commonly used welding method for vascular clamps. Before welding, the parts to be welded of the vascular clamps need to be carefully cleaned to remove impurities such as oil, rust and oxides on the surface to ensure that the brazing material can wet the base material well. Suitable brazing material and flux should be selected according to the material of the base material. The melting point of the brazing material should be lower than that of the base material so that welding can be achieved at a lower temperature.

[0003] However, during the welding process, due to the influence of the welding environment, oxygen in the air and impurities such as dust will affect the welding quality. Oxygen will produce oxides due to the increase in the temperature of the vascular clamp during welding. If there is a lot of moisture in the air or the vascular clamp is relatively moist, it will also cause the formation of pores, thus affecting the quality of welding. Summary of the invention

One end of the trapezoidal lock block penetrates through the rectangular limiting plate and is slidably connected to the rectangular limiting plate.

[0014] The present invention has the following beneficial effects: (1) The present invention provides a welding device for producing vascular clamps. The vascular clamps are placed in a welding box, and then the box door is closed and the vacuum pump is started. The vacuum pump starts to suck air and draws air into the welding box through the suction pipe. Since the cross slide is not in a closed state at this time, the outside air will enter the welding box under the action of the vacuum pump. In this process, the air will pass through a number of heating pipes when entering the welding box from the cross slide. Under the condition of heating, the hot air will dry the vascular clamps and other facilities in the welding box, so that the moisture in the welding box is sucked out of the welding box under the action of the vacuum pump. At the same time, the vacuum pump will also suck the dust and impurities in the welding box out of the welding box, thereby reducing the objective influence of moisture, impurities and dust, and preventing the occurrence of welding slag and pores during welding. The sucked air will be discharged into the transmission bellows through the outlet pipe, and the wind will drive the round block to move away from the vacuum pump. When the air in the welding box is fully closed, the round block will move, and the transmission rod will move, and the transmission bellows will move. At this time, the closing spring will be compressed and deformed. After the dust and impurities in the welding box are completely sucked out, the transmission bellows will close the cross slot, so that the welding box is in a completely closed state. Because the air in the welding box has not been completely pumped out at this time, the vacuum pump continues to run, and the round block will pass through the exhaust slot during the continuous advancement of the round block. At this time, the closing spring will be further compressed. As the gas in the transmission bellows gathers more and more, the gas will be discharged from the gap between the round block and the exhaust slot. When the welding box is completely vacuumed, the vacuum pump stops running. Under the elastic force of the closing spring, the round block will move a short distance toward the vacuum pump again. At this time, the round block will cover the exhaust slot, thereby avoiding air leakage, so that the closing plate can stably close the cross slot and maintain the vacuum state in the welding box. (2) The present invention provides a welding device for producing vascular clamps. When the transmission rod moves in a direction away from the vacuum pump, the transmission rod drives the L-shaped plate to move, and the L-shaped plate drives a plurality of trapezoidal blocks to touch the L-shaped transmission plate. Under the action of the inclined surface of the trapezoidal block, the trapezoidal block passes through the L-shaped transmission plate, and the L-shaped transmission plate moves upward. The L-shaped transmission plate drives the rectangular movable frame to rise. At this time, the dust removal spring is elastically compressed. After the trapezoidal block leaves the L-shaped transmission plate, the L-shaped transmission plate descends under the action of the dust removal spring. During this process, the rectangular movable frame reciprocates up and down. The rectangular movable frame drives a plurality of scrapers to clean the dust and impurities on the surface of the dust filter plate to prevent the dust and impurities from clogging the filter holes on the dust filter plate, thereby affecting the smoothness of the vacuum pump when sucking air and reducing the amount of air entering the welding box. The amount of air intake affects the dryness of the welding box. (3) The present invention provides a welding device for producing vascular clamps. During the process of dust removal and air suction of the welding box, since the external gas enters the welding box from the cross slide, and the air blows toward the box door when entering the welding box from the cross slide, it is necessary to start the hydraulic cylinder before closing the box door. The hydraulic cylinder drives the special-shaped plate to descend, and the special-shaped plate drives the two rectangular boxes to descend. The trapezoidal locking block in the rectangular box will slide out of the welding box under the action of the inclined surface. At this time, the box door and the rectangular limiting plate are installed on the welding box, and the hydraulic cylinder is started again to raise the special-shaped plate. During the process of the special-shaped plate rising, the rectangular rod drives the rectangular box to rise under the action of the self-locking spring. When the trapezoidal locking block contacts the notch on the welding box, the adaptive spring that has been in a compressed state will push the trapezoidal locking block in the rectangular box to insert into the welding box and penetrate the rectangular limiting plate. At this time, the rectangular limiting plate and the box door are fixed, so as to prevent the wind entering the welding box from the cross slide from blowing the box door off or causing the welding box to be unable to be completely sealed. (4) The present invention provides a welding device for producing vascular clamps. After welding is completed, the hydraulic cylinder is started, and the hydraulic cylinder drives the special-shaped plate to descend. When the special-shaped plate descends, it not only pushes the trapezoidal locking block out of the welding box to unlock the box door, but also drives the L-shaped plate to descend. The L-shaped plate slides downward in the transmission bellows. At this time, the rectangular groove on the L-shaped plate is half exposed outside the transmission bellows and half inside the transmission bellows. At this time, the air in the transmission bellows and the air outlet pipe is discharged from the rectangular groove. Since the round block has no gas support, the closing plate opens the cross slide groove under the elastic force of a plurality of closing springs. At this time, the box door is opened to allow air circulation in the welding box, which can improve the cooling effect of the vascular clamp in the welding box.

[0015] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Please refer to Figure 1 - Figure 8 As shown in the [figures], the present invention is a welding device for the production of hemostatic forceps, including a welding box 1. A closing mechanism is provided on the welding box 1. The closing mechanism includes a vacuum pump 101 fixedly installed on the back of the welding box 1. An air suction pipe 102 and an air outlet pipe 103 are fixedly installed on the outer wall of the vacuum pump 101. The end of the air suction pipe 102 is fixedly connected to the welding box 1.

A strip groove 110 is opened on the back of the welding box 1, and the strip groove 110 is communicated with the cross slide groove 104. The transmission rod 109 passes through the strip groove 110 and is fixedly connected to the closing plate 106.

[0021] like Figure 4 As shown, the transmission bellows 107 is provided with an opening and closing mechanism 2, which includes an exhaust groove 201 opened on the back of the transmission bellows 107, and an L-shaped plate 202 is slidably installed in the transmission bellows 107. The L-shaped plate 202 passes through the transmission bellows 107, and a rectangular groove 203 is opened on the L-shaped plate 202.

[0022] The gas will be discharged from the gap between the round block 108 and the exhaust groove 201. When the welding box 1 is completely vacuumed, the vacuum pump 101 stops running. Under the elastic force of the closing spring 105, the round block 108 will move a short distance toward the vacuum pump 101 again. At this time, the round block 108 will cover the exhaust groove 201 to prevent air leakage, so that the closing plate 106 can stably close the cross slide groove 104 to maintain the vacuum state in the welding box 1.

[0023] like Figure 5 As shown, a dust removal mechanism is provided on the back of the welding box 1, and the dust removal mechanism includes a rectangular frame 301 fixedly installed on the back of the welding box 1, a dust filter plate 302 is fixedly installed on the back of the welding box 1, a slide bar 303 is fixedly installed on the top inner wall of the rectangular frame 301, a rectangular movable frame 304 is slidably sleeved on the slide bar 303, the rectangular movable frame 304 is slidably connected to the rectangular frame 301, a dust removal spring 305 is sleeved on the slide bar 303, the top end of the dust removal spring 305 is fixedly connected to the rectangular frame 301, the bottom end of the dust removal spring 305 is fixedly connected to the rectangular movable frame 304, a plurality of scrapers 306 are fixedly installed in the rectangular movable frame 304, and the slide bar 303 passes through the plurality of scrapers 306 and is slidably connected to the plurality of scrapers 306.

[0024] During this process, the rectangular movable frame 304 moves up and down, and the rectangular movable frame 304 will drive a number of scrapers 306 to clean the dust and impurities on the surface of the dust filter plate 302 to prevent the dust and impurities from clogging the filter holes on the dust filter plate 302, thereby affecting the smoothness of the vacuum pump 101 when sucking air and reducing the amount of air entering the welding box 1. The amount of air intake will affect the degree of dryness in the welding box 1.

[0025] As shown Figure 5 in FIG. 2, a reciprocating mechanism 4 is provided on the back surface of the rectangular frame 301. The reciprocating mechanism 4 includes an L-shaped transmission plate 401 fixedly installed on the back surface of the rectangular frame 301. An L-shaped flat plate 402 is fixedly installed on the transmission rod 109, and a plurality of trapezoidal blocks 403 are fixedly installed on the top of the L-shaped flat plate 402.

[0026] The transmission rod 109 drives the L-shaped flat plate 402 to move. The L-shaped flat plate 402 drives a plurality of trapezoidal blocks 403 to touch the L-shaped transmission plate 401. Under the action of the inclined surface of the trapezoidal block 403, the trapezoidal block 403 passes through the L-shaped transmission plate 401, and the L-shaped transmission plate 401 moves upward. The L-shaped transmission plate 401 drives the rectangular movable frame 304 to rise. At this time, the dust removal spring 305 is elastically compressed. After the trapezoidal block 403 leaves the L-shaped transmission plate 401, the L-shaped transmission plate 401 descends under the action of the dust removal spring 305.

[0027] As shown Figure 7 in FIG. 3, a drying mechanism is provided in the welding box 1. The drying mechanism includes a heating box 501 fixedly installed in the welding box 1. A plurality of air outlet holes 502 are opened on the heating box 501, and a plurality of heating tubes 503 are fixedly installed in the heating box 501.

[0028] External air enters the welding box 1 under the action of the vacuum pump 101. During this process, when the air enters the welding box 1 from the cross-shaped chute 104, it passes through a plurality of heating tubes 503. In the case of heating, the hot air dries the hemostatic forceps and other facilities in the welding box 1.

[0029] As shown Figure 7 in FIG. 4, a sealing mechanism is provided on the front surface of the welding box 1. The sealing mechanism includes a box door 601 provided on the front surface of the welding box 1. A rectangular limiting plate 602 is fixedly installed on the back surface of the box door 601, and the end of the rectangular limiting plate 602 extends into the welding box 1 and is slidably connected to the welding box 1.

[0030] The trapezoidal lock block 805 is inserted into the welding box 1 and penetrates through the rectangular limiting plate 602. At this time, the rectangular limiting plate 602 and the box door 601 are fixed, preventing the wind entering the welding box 1 from the cross-shaped chute 104 from blowing off the box door 601 or causing the welding box 1 to not be completely sealed.

[0031] As shown Figure 2 in FIG. 5, a driving mechanism 7 is provided on the welding box 1. The driving mechanism 7 includes a U-shaped mounting plate 701 fixedly installed on the top of the welding box 1. A hydraulic cylinder 702 is fixedly installed on the inner wall of the bottom of the U-shaped mounting plate 701. An abnormal-shaped plate 703 is fixedly installed on the output shaft of the hydraulic cylinder 702. The front surface of the L-shaped plate 202 is fixedly connected to the abnormal-shaped plate 703.

[0032] After welding is completed, the hydraulic cylinder 702 is activated. The hydraulic cylinder 702 drives the special-shaped plate 703 to descend. When the special-shaped plate 703 descends, it will not only push the trapezoidal lock block 805 out of the welding box 1 to unlock the box door 601, but the special-shaped plate 703 will also drive the L-shaped plate 202 to descend, and the L-shaped plate 202 will slide downward within the transmission air box 107.

[0033] As Figure 7 and Figure 8 shown, two self-locking mechanisms are provided on the welding box 1. The self-locking mechanism includes a U-shaped mounting frame 801 fixedly installed on the right side of the welding box 1. A rectangular rod 802 is fixedly installed on the U-shaped mounting frame 801. A rectangular box 803 is slidably sleeved on the rectangular rod 802. A self-locking spring 804 is fixedly installed on the bottom inner wall of the U-shaped mounting frame 801. The top end of the self-locking spring 804 is fixedly connected to the rectangular box 803. An adaptation spring 806 is fixedly installed on the right inner wall of the rectangular box 803. The left end of the adaptation spring 806 is fixedly installed with a trapezoidal lock block 805. The left end of the trapezoidal lock block 805 penetrates through the rectangular limit plate 602 and is slidably connected to the rectangular limit plate 602.

[0034] During the ascending process of the special-shaped plate 703, the rectangular rod 802 will drive the rectangular box 803 to ascend under the action of the self-locking spring 804. When the trapezoidal lock block 805 contacts the notch on the welding box 1, the adaptation spring 806 that has been in a compressed state will push the trapezoidal lock block 805 into the welding box 1 and penetrate through the rectangular limit plate 602 within the rectangular box 803.

[0035] When in use, place the vascular clamp in the welding box 1, then close the box door 601, start the vacuum pump 101, and the vacuum pump 101 starts to suck air and draws air into the welding box 1 through the suction pipe 102. Since the cross slot 104 is not closed at this time, the outside air will enter the welding box 1 under the action of the vacuum pump 101. In this process, the air will pass through a number of heating tubes 503 when entering the welding box 1 from the cross slot 104. Under the heating condition, the hot air will dry the vascular clamp and other facilities in the welding box 1, so that the moisture in the welding box 1 is sucked out of the welding box 1 under the action of the vacuum pump 101. At the same time, the vacuum pump 101 will also suck out the dust and impurities in the welding box 1 The air sucked out of the welding box 1 will be discharged into the transmission bellows 107 through the air outlet pipe 103, and the wind will drive the round block 108 to move away from the vacuum pump 101, and the round block 108 will drive the transmission rod 109 to move, and the transmission rod 109 will drive the closing plate 106 to move. At this time, several closing springs 105 are compressed and deformed. After the dust and impurities in the welding box 1 are completely sucked out, the closing plate 106 will close the cross slide 104 to make the welding box 1 completely closed. At this time, the air in the welding box 1 has not been completely sucked out, and the vacuum pump 101 continues to run. During the continuous advancement of the round block 108, it will pass through the exhaust groove 201, and the closing spring 105 will be further compressed. As the gas in the transmission bellows 107 gathers more and more, the gas will be discharged from the gap between the round block 108 and the exhaust groove 201. When the welding box 1 is completely vacuumed, the vacuum pump 101 stops running. Under the elastic force of the closing spring 105, the round block 108 will move a short distance toward the vacuum pump 101 again. At this time, the round block 108 will cover the exhaust groove 201 to prevent air leakage, so that the closing plate 106 can stably close the cross slide 104 to maintain the vacuum state in the welding box 1. When the transmission rod 109 moves away from the vacuum pump 101, the transmission rod 109 will drive the L-shaped plate 402 to move, and the L-shaped plate 402 will drive a number of trapezoidal blocks 40 3 touches the L-shaped transmission plate 401. Under the action of the inclined surface of the trapezoidal block 403, the trapezoidal block 403 will pass through the L-shaped transmission plate 401, and the L-shaped transmission plate 401 will move upward. The L-shaped transmission plate 401 will drive the rectangular movable frame 304 to rise. At this time, the dust removal spring 305 is elastically compressed. After the trapezoidal block 403 leaves the L-shaped transmission plate 401, the L-shaped transmission plate 401 will descend under the action of the dust removal spring 305. In this process, the rectangular movable frame 304 moves up and down reciprocatingly. The rectangular movable frame 304 will drive a number of scrapers 306 to clean the dust impurities on the surface of the dust filter plate 302 to prevent the dust impurities from clogging the filter holes on the dust filter plate 302. During the process of dust removal and air suction of the welding box 1, since the external gas enters the welding box 1 from the cross slide 104, and the air will blow towards the box door 601 when entering the welding box 1 from the cross slide 104, it is necessary to start the hydraulic cylinder 702 before closing the box door 601. The hydraulic cylinder 702 drives the special-shaped plate 703 to descend, and the special-shaped plate 703 drives the two rectangular boxes 803 to descend. The trapezoidal locking block 805 in the rectangular box 803 will slide out of the welding box 1 under the action of the inclined surface. At this time, the box door 601 and the rectangular limiting plate 602 are installed on the welding box 1, and the hydraulic cylinder 702 is started again to raise the special-shaped plate 703. During the rising process of the special-shaped plate 703, the rectangular rod 802 will drive the rectangular box 803 to rise under the action of the self-locking spring 804. When the trapezoidal locking block 805 contacts the notch on the welding box 1, the adaptive spring 806 which has been in a compressed state will be in the rectangular box 803. The trapezoidal locking block 805 is pushed to be inserted into the welding box 1 and pass through the rectangular limiting plate 602. At this time, the rectangular limiting plate 602 and the box door 601 are fixed; after the welding is completed, the hydraulic cylinder 702 is started, and the hydraulic cylinder 702 drives the special-shaped plate 703 to descend. When the special-shaped plate 703 descends, it will not only push the trapezoidal locking block 805 out of the welding box 1 to unlock the box door 601, but also drive the L-shaped plate 202 to descend. The L-shaped plate 202 will slide downward in the transmission bellows 107. At this time, the rectangular groove 203 on the L-shaped plate 202 will be half exposed outside the transmission bellows 107, and half will be inside the transmission bellows 107. At this time, the air in the transmission bellows 107 and the air outlet pipe 103 will be discharged from the rectangular groove 203. Since the round block 108 has no gas support, the closing plate 106 will open the cross slide groove 104 under the elastic force of several closing springs 105, and the box door 601 is opened at this time.
