Description

Technical Field

[0001] The invention belongs to the technical field of special tooling, and is particularly suitable for material return in the process of manufacturing a cylindrical cylinder body, and specifically relates to an automatic material return device for stamping a cylindrical cylinder body. Background Art

[0002] The cylindrical barrel type gas cylinder body is obtained by stamping the material block by the stamping production system. The stamping production system is mainly composed of a punch, a stamping die, a stamping support, etc. assembled on a press. Specifically, during the stamping process, the punch of the stamping production system presses down the material block placed in the stamping die, so that the stamped material block forms a cylindrical barrel workpiece (that is, the gas cylinder body required for subsequent production). After the punch punches the material block to form a cylindrical barrel workpiece, the cylindrical barrel workpiece will fit tightly with the punch, and external force is needed to withdraw the cylindrical barrel workpiece from the punch. The process of withdrawing the cylindrical barrel workpiece from the punch is called material withdrawal.

[0003] Since the diameter and length of each workpiece punched out by punches and stamping dies of different specifications are also different, it will cause certain difficulties in material removal. In the past, the material removal method was that the staff used tools to operate the material removal. During the stamping process, the punch carried the workpiece to the bottom of the stamping bracket, and then the stamping was stopped. At this time, the operator inserted the fork-type material removal fork between the workpiece and the stamping bracket. When the punch brought the workpiece back upward, the lower surface of the material removal fork was stuck on the upper side of the workpiece barrel wall, and the upper surface of the material removal fork was in contact with the stamping bracket and blocked by the stamping bracket. This blocking force acted on the upper side of the workpiece barrel wall, which can make the workpiece withdraw from the punch and complete the manual material removal.

[0004] The above-mentioned method of using tools to operate the material return has the following disadvantages: the main one is low efficiency; secondly, the different consistency of tool operation by different operators and fatigue operation will affect the result of material return, which is easy to affect the quality of the workpiece and the yield rate; in addition, the labor intensity is high, and manual material return operation is prone to production accidents, causing personal injury. Nowadays, society is developing faster and faster, and the manufacturing level is getting higher and higher. While improving product quality, it is also necessary to improve product processing efficiency. Processing efficiency is a reflection of the competitiveness of a product or even an enterprise; therefore, the development of an automatic material return device that can replace the above-mentioned manual material return and can improve the efficiency and reliability of material return is particularly important.

[0024] like Figure 1 As shown, the material withdrawal seat 1 and the pressure cover 2 are both annular structures, and four slide grooves 10 are arranged at equal intervals on the material withdrawal seat 1, and the material withdrawal slider 11 is correspondingly installed in the four slide grooves 10, and the inner side of the material withdrawal slider 11 is an arc corresponding to the inner circle of the material withdrawal seat 1 and the pressure cover 2, and the material withdrawal seat 1 is provided with a stepped card groove 25 that is matched with the pressure cover 2, and the pressure cover 2 is fixedly connected to the material withdrawal seat 1 by the pressure cover fixing hexagon socket screw 12; it should be noted that the design of the material withdrawal slider 11 and the number and size of the slide grooves 10 can be configured according to actual needs, and the present invention discloses only a preferred design.

[0025] A roller placement groove 15 is provided at the inner center of the material return slider 11, and a workpiece material return roller 16 is installed in the roller placement groove 15, and the workpiece material return roller 16 protrudes from the inner arc surface of the material return slider 11; an axis mounting position 17 is provided inside the material return slider 11, and a bearing shaft 3 is fixedly installed on the shaft mounting position 17, and the bearing shaft 3 passes through the roller placement groove 15 and is matched and connected with the workpiece material return roller 16.

[0026] The cylindrical helical compression spring 4 and the spring positioning rod 5 are symmetrically arranged on both sides of the adjusting screw 9, and the embedding grooves 13 are symmetrically arranged on the material withdrawal slider 11 and on both sides of the adjusting screw 9, and the cylindrical helical compression spring 4 and the spring positioning rod 5 that are connected to each other are installed in the embedding grooves 13.

[0027] The adjusting screw 9 and the material return slider 11 are fixedly connected by a screw fixing hexagon socket screw 20. A fixing hole 14 is provided at the connecting end of the adjusting screw 9 and the material return slider 11. The screw fixing hexagon socket screw 20 passes through the material return slider 11 and is inserted into the fixing hole 14 of the adjusting screw 9.

[0028] A plurality of anti-loosening nuts are arranged on the adjusting screw 9 located at the rear side of the screw movement control nut 8 , and a nut rotation groove 19 cooperating with the screw movement control nut 8 is arranged on the outer circle of the material withdrawal seat 1 .

[0029] The spring positioning rod 5 is provided with a groove which cooperates with the hexagon socket spring adjusting screw 7 . The hexagon socket spring adjusting screw 7 abuts against the groove. The hexagon socket spring adjusting screw 7 is provided with a fastening nut 6 .

[0030] The material-removing seat 1 and the pressure cover 2 are also provided with a penetrating device installation hole 18 , and the automatic material-removing device is fixedly connected to the stamping bracket 23 via a device fixing bolt passing through the device installation hole 18 .

[0031] Reference Figure 3 and Figure 4 As shown, before stamping, the device fixing bolts are first passed through the device mounting holes 18 of the material stripping seat 1 and the pressure cover 2 to fix the automatic material stripping device on the stamping bracket 23. By screwing the screw movement control nut 8, the adjusting screw 9 can drive the material stripping slider 11 to move, so as to adjust the front and rear positions of the material stripping slider 11 to adapt to the material stripping of cylindrical barrel workpieces 24 with different diameters and wall thicknesses. In the actual stamping process, the material stripping slider 11 needs to block the upper end section of the cylindrical barrel workpiece 24 as moderately as possible. Too little blocking may damage the cylindrical barrel workpiece 24, and too much blocking may connect with the punch 21 and damage the punch 21. After the material stripping slider 11 is adjusted to the appropriate position, a plurality of anti-loosening nuts are screwed and fixed on the adjusting screw 9 on the rear side of the screw movement control nut 8 to play a role in fixing and preventing loosening. In addition, after long-term use, the elastic force of the cylindrical helical compression spring 4 may change. At this time, it is necessary to rotate the hexagonal spring adjustment screw 7 to push the spring positioning rod 5 inserted in the cylindrical helical compression spring 4 to adjust the elastic force of the cylindrical helical compression spring 4 and ensure that the material return slider 11 can be reset to the appropriate position of the initial adjustment.

[0032] Reference Figure 3 and Figure 4As shown, during the stamping process, the punch 21 carries the material block through the stamping die 22, so that the material block is deformed into a cylindrical barrel workpiece 24. The cylindrical barrel workpiece 24 passes through the automatic material stripping device, and the cylindrical barrel workpiece 24 slides on the workpiece stripping roller 16 of the automatic material stripping device. The workpiece stripping roller 16 pushes the stripping slider 11 through the bearing shaft 3 under the action of the axial force to stamp in the opposite direction of the cylindrical barrel workpiece 24, compressing the cylindrical helical compression spring 4 sleeved on the spring positioning rod 5, and the stripping slider 11 moves backward; when the cylindrical barrel After the cylindrical workpiece 24 passes through the automatic material stripping device, the cylindrical helical compression spring 4 pushes the material stripping slider 11 back, and the inner side of the material stripping slider 11 is withdrawn to just above the inner wall of the cylindrical barrel workpiece 24. When the punch 21 is withdrawn, it drives the cylindrical barrel workpiece 24 upward, and the wall of the cylindrical barrel workpiece 24 will be stuck on the material stripping slider 11. The punch 21 is driven by the press and pulled out from above. The cylindrical barrel workpiece 24 is blocked by the material stripping slider 11, and the cylindrical barrel workpiece 24 falls, completing the automatic material stripping of the cylindrical barrel workpiece 24 formed by stamping.

[0033] In summary, the automatic material-removing device for stamping a cylindrical barrel of the present invention has the following advantages:

[0034] 1. Automatic material withdrawal function: through the use of the automatic material withdrawal device, the cylindrical barrel workpiece 24 formed by stamping can be automatically withdrawn from the punch 21, thereby improving production efficiency.

[0035] 2. The automatic material-removing device has an adjustable material-removing range for the cylindrical barrel workpiece 24. The front and rear positions of the material-removing slider 11 in the slide groove 10 on the material-removing seat 1 can be adjusted by the adjusting screw 9 of the automatic control component to adapt to workpieces of different diameters and wall thicknesses, and can cover the processing of workpieces within a certain size range.

[0036] 3. The pressure of the cylindrical helical compression spring 4 of the automatic material stripping device is adjustable. After long-term use, the elastic force of the cylindrical helical compression spring 4 will change, which can be adjusted by the hexagonal spring adjustment screw 7 to ensure the elastic force function of the cylindrical helical compression spring 4. In addition, the material stripping slider 11 of the automatic material stripping device is pushed forward by the extension and contraction of the cylindrical helical compression spring 4. The cylindrical helical compression spring 4 is used to reset the material stripping slider 11 during stamping work.

[0037] 4. The workpiece unloading roller 16 of the automatic unloading device can rotate. During the stamping process, when the punch 21 carries the cylindrical workpiece 24 through the workpiece unloading roller 16, the workpiece unloading roller 16 can rotate on the bearing shaft 3. When the cylindrical workpiece 24 passes through, it does not hinder the stamping process, avoiding hard contact and affecting the life of the unloading device.

[0038] The material withdrawal of the cylindrical barrel workpiece 24 requires frequent operations and single actions, and accidents are frequent and the efficiency is low when it relies on manual operation. The automatic material withdrawal device for stamping a cylindrical barrel provided by the present invention is an automatic material withdrawal tool designed for the material withdrawal process in the processing of the cylindrical barrel workpiece 24. In the past, operators used tools to operate the material withdrawal, which often took up more than half of the time in the entire production process. The automatic material withdrawal device of the present invention can automate the material withdrawal of the cylindrical barrel workpiece 24 and at least double the work efficiency. During the stamping process, as the punch 21 descends, the workpiece stripping roller 16 slides on the surface of the cylindrical workpiece 24, pushing the stripping slider 11 to retreat. After the cylindrical workpiece 24 has completely passed, the pressure of the cylindrical helical compression spring 4 is released, pushing the stripping slider 11 back to its original position. When the punch 21 returns upward with the cylindrical workpiece 24, the cylindrical workpiece 24 is stuck under the stripping slider 11, and is stripped off from the punch 21 by the obstruction of the stripping slider 11, thereby realizing automatic stripping.

[0039] It can be understood that the above specific description of the present invention is only used to illustrate the present invention and is not limited to the technical solutions described in the embodiments of the present invention. Those skilled in the art should understand that the present invention can still be modified or replaced by equivalents to achieve the same technical effects; as long as the use requirements are met, they are within the protection scope of the present invention.
