Description

[0001] Method and device for producing sleeves

[0002] The invention relates to a method for producing casings, in particular artillery gun and / or grenade casings, from a metal, in particular a steel material. Also disclosed is a system for producing such casings, or a system configured to carry out the method according to the invention.

[0003] Sleeves can be manufactured from a steel material, which is usually in bar form. From these steel bars, sleeve blanks of a defined length can be cut, which are then heated and formed through further processing steps into sleeves with a defined shape, particularly length and wall thickness.

[0004] The present invention is based on the object of permitting the production of casings, in particular artillery gun and / or grenade casings, with a shorter cycle time than known in the prior art. This enables accelerated production of casings.

[0005] The objects on which the present invention is based are achieved by a method having the features of claim 1, and by a system having the features of claim 11. Advantageous embodiments are set out in the dependent claims. More specifically, the object on which the present invention is based is achieved by a method for producing cases, in particular artillery gun cases and / or grenade cases, comprising the steps of: a) inserting a first heated case blank into the die of a hole-pressing device; b) forming the first case blank into a first case in a first forming operation and using the hole-pressing device; c) removing the first case from the die of the hole-pressing device; d) inserting the first case into a drawing-pressing device; e) forming the first case in a second forming operation and using the drawing-pressing device; and f) removing the case from the drawing-pressing device.

[0006] The method according to the invention is characterized in that after step c) and before step f) a second heated sleeve blank is inserted into the die of the hole pressing device and the second forming operation of the first sleeve takes place at least partly simultaneously with the first forming operation of the second sleeve blank.

[0007] In other words, an essential aspect of the invention can be seen in the fact that, while the first sleeve is being drawn / formed by means of the drawing-pressing device, a second sleeve blank is already being formed into a sleeve by means of the piercing-pressing device. This achieves a significant reduction in cycle time compared to the prior art.

[0008] The casings produced can, in principle, be any type of casing, in particular made of a metal and / or a steel alloy. Particularly preferred casings include artillery gun casings and / or grenade casings. The casings can have a defined contour and / or wall thickness. In step a) of the method according to the invention, a first heated casing blank is inserted into the die of a punching device.

[0009] The sleeve blank can have been separated beforehand from a rod-shaped base body, in particular a rod-shaped steel material, by means of a separating device. A saw can preferably be used as the separating device, although other alternatives such as guillotine shears are also conceivable. Likewise beforehand, either the sleeve blank and / or the rod-shaped base body can have been heated by means of a heating device, preferably an induction heating device. When the sleeve blank is inserted into the die of the hole pressing device, it preferably has a temperature in the range of > 800 ° C and < 1300 ° C, more preferably > 1000 ° C and < 1250 ° C, even more preferably > 1100 ° C and < 1200 ° C.

[0010] The insertion of the sleeve blank into the die of the punching device can preferably be carried out using a manipulator device, in particular a single-arm robot. The same applies to the removal of the sleeve from the die and / or the insertion of the sleeve into the drawing device.

[0011] The die of the punching device, which can also be referred to as a die, has a cavity into which the sleeve blank can be inserted. The cavity of the die can completely accommodate the inserted sleeve blank. The cavity of the die of the punching device also has a longitudinal direction that runs essentially parallel to the direction of insertion of the sleeve blank into the die.

[0012] In step b) of the method according to the invention, the first sleeve blank is formed into a first sleeve. A first tool of the punching device can be lowered and inserted into the cavity of the die. Under pressure from the punching device, the sleeve blank located in the cavity of the die is then formed into a sleeve in a first forming operation.

[0013] In step c) of the method according to the invention, the first sleeve thus produced is removed from the die of the punching device. As previously described, a manipulator device, in particular in the form of a single-arm robot, can be used for this purpose. The manipulator device for removing the sleeve is preferably a different manipulator device than the one used for inserting the sleeve blank into the die. This advantageously allows the cycle time to be significantly reduced.

[0014] In step d) of the method according to the invention, the sleeve removed from the punching device is inserted into the drawing device. This insertion into the drawing device is particularly preferably carried out using the same manipulator device that was used to remove the sleeve from the punching device. This again advantageously further reduces the cycle time.

[0015] In step e) of the method according to the invention, a second forming operation takes place in which the inserted sleeve is formed again by means of the drawing press device. The sleeve can be inserted into the drawing carriage of the drawing press device and with its help drawn over a drawing mandrel. The sleeve is formed between the drawing mandrel and at least one drawing ring of the drawing carriage into the desired shape, in particular with regard to the wall thickness. The sleeve formed again in this way can also be referred to as a calibrated sleeve. In step f) of the method according to the invention, the produced sleeve is then removed from the drawing press device. Removal can also be understood as ejecting and / or stripping the sleeve from the drawing press device or from the drawing mandrel.

[0016] Step f) can be followed by further steps to prepare the produced sleeve for its final use. For example, cutting the sleeve to length, for example using a saw, can be mentioned here. Step f) is particularly preferably followed by a step of cooling the removed sleeve. This cooling step can preferably be carried out as a two-stage process. In particular, passive cooling to a first temperature can first take place, followed by active cooling to a second temperature which is below the first temperature. Passive cooling can in particular be understood to mean leaving the sleeve to stand at room temperature. Active cooling can in particular be understood to mean supplying a cooling fluid flow, in particular an air flow or a cooled air flow, directed onto the sleeve.Preferably, the first temperature is in a range of > 400 ° C and < 700 ° C , more preferably > 500 ° C and < 600 ° C, or about 550 ° C .

[0017] As explained above, according to the invention, after step c) and before step f), a second heated sleeve blank is inserted into the die of the hole-pressing device. This means that a further first forming operation (of the second heated sleeve blank) can already take place, while the first sleeve, which was produced from the first heated sleeve blank, undergoes its second forming operation. This results in a significant shortening of the cycle time. The first forming operation, which is carried out by means of the hole-pressing device, can comprise several, in particular two, forming steps.

[0018] Particularly preferably, these steps involve upsetting or reverse extrusion. Even more preferably, these two steps are carried out directly one after the other, i.e., without any further forming steps in between. Likewise, these steps can preferably be carried out using different tools of the punching device.

[0019] Upsetting can be carried out using a first upsetting tool, in particular an upsetting mandrel. Backward extrusion can be carried out using a second tool, in particular a piercing mandrel. The upsetting mandrel can have a convex end at its distal end, i.e. the end inserted into the cavity of the die. This allows centering to take place simultaneously during upsetting. The upsetting mandrel can be made of one piece or several pieces with its convex end.

[0020] Particularly preferably, the second forming operation of the first sleeve by means of the drawing press device can be carried out at least partially simultaneously with the forming step of backward extrusion of the first forming operation of a second sleeve blank which was inserted into the die of the piercing press device after the first sleeve blank.

[0021] Likewise particularly preferably, the hole pressing device can have at least two second tools, in particular in the form of piercing mandrels. This allows the two second tools to be used alternately in the first forming operation. This advantageously achieves a longer service life for the second tools. Further preferably, the second tool which is not being used at a time can be cooled at least temporarily during the period until it is used again. Preferably, the cooling is active cooling. Preferably, for the active cooling, the tool to be cooled can be sprayed with a spray mist, preferably a water-graphite spray mist.

[0022] For example, the piercing device can have at least two piercing mandrels as a second tool, the first piercing mandrel being used during the first forming operation of the first heated sleeve blank and the second piercing mandrel being used during the first forming operation of the second heated sleeve blank. Furthermore, the first piercing mandrel can then be actively cooled after step b) and optionally at least partially until the first forming operation of a third heated sleeve blank. Particularly preferably, the first piercing mandrel is cooled during the first forming operation, more preferably during the upsetting of the second heated sleeve blank. As described with reference to the system, in this preferred variant the two piercing mandrels and the upsetting mandrel can be arranged on a movable, in particular a linearly movable, tool carriage of the piercing device.The movable tool slide can also be called a mandrel shifting unit.

[0023] Likewise, the upsetting tool, in particular the upsetting mandrel, can preferably be cooled, in particular actively cooled, during the reverse extrusion step. For active cooling, the tool to be cooled can preferably be sprayed with a spray, preferably a water-graphite spray.

[0024] For the active cooling of the tools, the system according to the invention can comprise a cooling device, in particular a cooling unit configured to spray a tool with a spray mist, preferably a water-graphite spray mist. Cooling devices with different cooling media can preferably be provided for each tool to be cooled. For example, a first cooling device for cooling a piercing mandrel can contain a first cooling medium, and a second cooling unit for cooling the upsetting mandrel can contain a second cooling medium.

[0025] Between step c) according to the invention and step d) according to the invention, the sleeve can also be blown out, in particular with compressed air. For this purpose, the system according to the invention can have a compressed air-operated blow-out unit. Preferably, the sleeve can first be removed from the piercing press device by the same manipulator device, then fed to the blow-out unit, and inserted into the drawing press device after blow-out. This again advantageously shortens the cycle time.

[0026] The objects underlying the present invention are also achieved by a system for producing casings, in particular artillery gun and / or grenade casings. The system according to the invention comprises:

[0027] - at least one hole pressing device comprising at least one die, at least one hole carriage, at least one first tool for upsetting, and at least one, preferably at least two second tools for piercing the sleeve blank, wherein the first tool and the two second tools are arranged on a movable tool carriage or a rotary saddle;

[0028] - at least one drawing press device comprising at least one drawing mandrel and at least one drawing carriage with at least one, preferably at least four, drawing rings;

[0029] - at least one first manipulator device for inserting a first heated sleeve blank into the die of the punching device, and at least one second manipulator device for removing a sleeve from the punching device and / or for inserting a sleeve into the drawing device; - wherein the punching device is configured to carry out a first forming operation, in particular upsetting followed by reverse extrusion, of a heated sleeve blank into a sleeve, and wherein the drawing device is configured to carry out a second forming operation, in particular drawing, of the sleeve.

[0030] The system according to the invention is characterized in that it is designed to carry out the second forming operation at least partially simultaneously with the first forming operation.

[0031] Regarding the individual components of the system according to the invention, reference is made to the above explanations regarding the method according to the invention. Nevertheless, individual components will be discussed again below.

[0032] The punching press device and the drawing press device can be designed as a structural unit. In particular, they can use the same drive, especially a hydraulic drive. This not only reduces the footprint but also reduces the number of required components. Furthermore, the distances between the punching press device and the drawing press device can be reduced, allowing the workpiece to be transferred more quickly between the two devices. This shortens the cycle time.

[0033] The hole pressing device and / or the drawing pressing device and / or the first manipulator device and / or the second manipulator device can be operated hydraulically.

[0034] The first upsetting tool can be an upsetting mandrel. The first upsetting tool can be convex at the distal end. This advantageously achieves simultaneous upsetting and the formation of a centering. The second punching tool can be a punching mandrel. The punching device of the system according to the invention has at least two second punching tools, in particular two punching mandrels. The two second punching tools are preferably identical.

[0035] The first tool for upsetting and the two second tools for piercing are mounted on the movable tool carriage of the punching press. Thus, by moving the tool carriage, the tool required for each forming step can be selected. To select a tool, it can be positioned essentially centered above the cavity of the die.

[0036] The three tools (first tool, two second tools) are particularly preferably arranged along the longitudinal extent of the tool carriage, with the upsetting tool being arranged between the two punching tools. This makes it easy to switch back and forth between the upsetting tool and one of the two punching tools at a time. This arrangement is also further advantageous if the system according to the invention has a cooling device for the active cooling of the tools. Such a cooling device can preferably be arranged on at least one side or on two opposite sides of the punching device, in such a way that moving the tool carriage arranges the first tool or a second tool above the cooling device when the tool is not in use.When the active tool is lowered into the cavity, the inactive tool is simultaneously lowered into the cooling device and cooled. The cooling device can be suitable or configured to at least partially accommodate the first tool for upsetting and / or the second tool for piercing. The tool carriage can be movable orthogonally to the longitudinal direction of the cavity of the die. As an alternative to a tool carriage, the tools can also be arranged on a rotary saddle. This also allows the tools to be changed.

[0037] The three tools can be arranged at an equidistant distance from one another on the tool slide, particularly in the case of a linearly movable tool slide.

[0038] The manipulator devices can be single-arm robots. These can preferably be designed as 5-, 6-, or 7-axis single-arm robots. The manipulator devices can have grippers, preferably parallel grippers or angular grippers, for gripping the workpieces.

[0039] The system according to the invention can further comprise a separating device for separating and preparing a sleeve blank from a rod-shaped steel material. In particular, the separating device can be a sawing device, but also, for example, a shearing machine.

[0040] The system according to the invention can further comprise a heating device. The heating device can be configured to heat the rod-shaped steel material and / or the sleeve blank separated therefrom. An induction heating device is particularly preferred, in particular for heating the sleeve blank.

[0041] The heated sleeve blank can then be fed to a transfer station, which can also be part of the system according to the invention. The heated sleeve blank can then be removed from the transfer station by means of the first manipulator device and fed to the piercing device. The system according to the invention can further comprise an ejection device arranged on the drawing press device. By means of the ejection device, the calibrated sleeve can be ejected from the drawing press device and / or stripped from the drawing mandrel.

[0042] Further advantages, details and features of the invention will become apparent from the following exemplary embodiments.

[0043] In detail:

[0044] Figure 1A: a perspective view of a part of the system according to the invention.

[0045] Figure 1B: a side view of the same part of the system according to the invention.

[0046] Figure 2 : an enlargement of a part of the hole pressing device in section .

[0047] Figure 3: another perspective view of the system according to the invention.

[0048] In the following description, identical reference symbols designate identical components or identical features, so that a description given with respect to one figure regarding a component also applies to the other figures, thus avoiding repetitive description. Furthermore, individual features described in connection with one embodiment can also be used separately in other embodiments.

[0049] Figures 1A and 1B show a perspective view and a side view, respectively, of the same part of the system 1 according to the invention, wherein the manipulator devices 16, 17 are not shown.

[0050] As can be seen in the two figures, the system 1 according to the invention comprises a punching device 2 and a drawing device 9, which are designed as a structural unit. Both the punching device 2 and the drawing device 9 are hydraulically operated.

[0051] The hole-pressing device 2 has a die 4 (better visible in Figure 2) and a hole carriage 3. Arranged on the hole carriage 3 is a movable tool carriage 8, which can be moved linearly out of and into the paper plane of Figure 1B. The tool carriage 8 can thus be moved orthogonally to the longitudinal direction of the cavity 14 (better visible in Figure 2).

[0052] In particular, it can be seen in Figure 1B that a piercing mandrel 7 is arranged as a second tool for piercing in the tool carriage 8 and can be moved along the longitudinal direction of the cavity 14 by means of the piercing carriage 3. As will be explained further with reference to Figure 2, in addition to the piercing mandrel 7 shown in Figure 1B, a further piercing mandrel 7 and an upsetting mandrel 5 are arranged as the first tool for upsetting in the tool carriage 8. It can also be seen from Figure 2 that the first or second tool 5, 7 arranged above the die 4 enters the cavity of the die 4 when the piercing carriage 3 is lowered.

[0053] In Figures 1A and 1B it can also be seen that the drawing press device 9 has a drawing mandrel 10 and a drawing carriage 11. The drawing carriage 11 also has four drawing rings 12. The system according to the invention also has two cooling devices 13 which are arranged on opposite sides of the piercing press device 2. The cooling devices 13 are designed to hold the first tool for upsetting 5 and the two second tools for piercing 7. Furthermore, the cooling devices 13 are designed to spray the held tools with a water-graphite spray in order to actively cool them efficiently.

[0054] Figure 2 shows an enlargement of a part of the hole pressing device 2 in section.

[0055] It can be seen that the movable tool carriage 8 has two second tools for punching 7 in the form of a punching mandrel, as well as a first tool for upsetting 5 in the form of an upsetting mandrel arranged centrally thereto.

[0056] The compression mandrel 5 has a convex distal end 6 which, in addition to the compression, also leads to the formation of a centering during the first forming operation in process step b).

[0057] As can also be seen, the upsetting mandrel 5 is located above the die 4 and could be lowered into the cavity of the die 4 to carry out the first forming operation in step b) of the method according to the invention. The upsetting mandrel 5 is therefore to be regarded as the currently active tool, whilst the piercing mandrels 7 are to be regarded as inactive tools. By moving the tool carriage 8 to the left or right in the plane of the paper in Figure 2, the piercing mandrel 7 shown to the right or left of the upsetting mandrel 5 could now be arranged above the cavity of the die 4 and become the active tool. The second forming operation of method step e) could then be carried out. Figure 3 shows the system 1 according to the invention. The method according to the invention will be explained in more detail below with reference to this figure.

[0058] A transfer station 19 can be seen, on which a heated sleeve blank 15 is positioned. The sleeve blank 15 consists of a steel alloy and was separated from a rod-shaped steel material by means of a cutting device (not shown) of the inventive system in the form of a saw. After the sleeve blank 15 was separated, it was heated to a temperature of approximately 1150°C in a heating device (also not shown) of the inventive system, which is designed as an induction heating device.

[0059] Also visible is a first manipulator device 16 in the form of a single-arm robot. The robot 16 has a parallel gripper on its arm, with which the heated sleeve blank 15 can be gripped and removed from the transfer station 19.

[0060] The single-arm robot 16 inserts the gripped, heated sleeve blank 15 into the die 4 of the punching device 2 in process step a). It then releases the sleeve blank 15 and removes its arm from the working area of ​​the punching device 2.

[0061] The linearly movable tool slide 8 of the hole pressing device 2 is positioned such that the first tool for upsetting 5, i.e. the upsetting mandrel with convex distal end 6, is arranged above the die 4 and is thus the active tool.

[0062] In method step b), the upsetting mandrel 5 is moved into the die 4 by the hole carriage 3 being moved down in order to carry out the first forming operation. The first forming step (upsetting) of the first forming operation is carried out by the pressure of the hole pressing device 2 acting on the sleeve blank 15 located in the die 4. Due to the convexly shaped distal end 6 of the upsetting mandrel 5, the sleeve blank 15 is not only upset, but a centering is also formed at the same time. While the upsetting mandrel 5 is moved into the die, one of the two piercing mandrels 7 - namely the one that was used in the previous cycle to form the sleeve blank 15 - is moved into the cooling device 13 in order to be actively cooled there.

[0063] After forming is complete, the piercing slide 3 is moved upwards to remove the upsetting mandrel 5 from the die 4. The movable tool slide 8 is then moved so that one of the two piercing mandrels 7 is now positioned above the die 4 and is thus the active tool.

[0064] The active piercing mandrel 6 can now be moved into the die 4 by lowering the piercing carriage 3 in order to perform the second forming step (backward extrusion) of the first forming operation. Due to the pressure of the piercing device 2, which acts via the piercing mandrel 6 on the material in the die 4, the upset and centered sleeve blank 15 is formed into a sleeve 18. While the piercing mandrel 6 is moved into the die, the previously used upsetting mandrel 5 is simultaneously moved into the cooling device 13 for active cooling.

[0065] After forming is complete, the piercing slide 3 is moved upwards to remove the piercing mandrel 6 from the die 4. The movable tool slide 8 can now be moved so that the upsetting mandrel 5 is once again the active tool.

[0066] As soon as the hole carriage 3 has been moved upwards and the piercing mandrel has been removed from the die 4, the produced sleeve can be removed from the die 4 of the hole-pressing device 2 in process step c). For this purpose, a further manipulator device 17, also in the form of a single-arm robot, is used. This second single-arm robot 17 also has a parallel gripper on its arm, with which the sleeve 18 can be gripped and removed from the hole-pressing device 2.

[0067] In the subsequent process step d), the second single-arm robot 17 inserts the sleeve 18 into the drawing-pressing device, in particular the drawing carriage 11 of the drawing-pressing device 9. It then releases the sleeve 18 and removes its arm from the working area of ​​the drawing-pressing device 9.

[0068] Before inserting the sleeve 18 into the drawing press device 9, the single-arm robot 17 can optionally feed the sleeve 18 to a compressed air-operated blow-out unit in order to blow out the sleeve.

[0069] Both single-arm robots 16 , 17 can be operated electromechanically and / or hydraulically.

[0070] In process step e), the second forming operation now follows, in which the sleeve 18 is formed into a calibrated sleeve using the drawing-press device 9. By moving the drawing carriage 11 along the longitudinal direction of the drawing mandrel 10, the sleeve 18 inserted into the drawing carriage 11 is drawn over the drawing mandrel 10 and, in the process, formed into the desired shape between the drawing rings 12 and the drawing mandrel 10. This second forming operation takes place at least partially simultaneously with the step of backward extrusion of a further heated sleeve blank 15 which has meanwhile been inserted into the die of the piercing device 2.

[0071] After process step e), the calibrated sleeve can be stripped from the drawing mandrel in process step f) by means of a stripping device of system 1 (not shown) and thus removed.
