Description

Technical Field

[0001] The utility model belongs to the technical field of hot die forging presses, and particularly relates to a movable die holder pulling-out mechanism for a hot die forging press. Background Art

[0002] At present, the die holder pulling-out device of large-tonnage hot die forging presses usually adopts a split structure. Steel plates need to be embedded in the foundation under the columns, and then the backing plates of the columns are welded to the embedded steel plates. The base and the bracket need to be fixed to the cement floor with expansion bolts. The connections of the guide rails to the base, bracket, columns, etc. all need to be installed on-site, which is rather troublesome during installation and later maintenance. Moreover, the motor and the sprocket are arranged on both sides, occupying a large space, being immovable, and a cover plate needs to be laid on the top, which is prone to potential safety hazards.

[0003] In addition, due to the long pulling-out and feeding strokes of the die holder pulling-out device, the middle of the chain is suspended without support during the transmission process. When stopping in the middle to replace the gripper, the connecting pin will come out, and manual assistance is required to realign it, which is troublesome to operate and has a low safety factor. And because the frequency of pulling out the main die holder from the press for replacement or maintenance is relatively low, the die holder pulling-out device is mostly in an idle state, and being fixed near the press occupies a lot of space. Therefore, based on these problems, it is urgent to develop a movable die holder pulling-out mechanism to better meet the actual use needs of users, which has important practical significance. Content of the Utility Model

[0004] Through research on the previous die holder pulling-out device, the utility model provides a movable die holder pulling-out mechanism for a hot die forging press to solve the problems existing in the current die holder pulling-out device and meet the needs of users.

[0005] The utility model is realized as follows. A movable die holder pulling-out mechanism for a hot die forging press includes a base, a motor reducer, a coupling, a small gear, a large gear, a sprocket, a chain, a guide rail, a bracket, and a towing frame. The base, the guide rail, and the bracket form an integral frame. The base is located at one end of the two guide rails. The motor reducer, the coupling, the small gear, and the large gear are all arranged on the base.

[0006] The output end of the motor reducer is connected to the small gear through the coupling. The small gear meshes with the large gear. Two sprockets and the large gear are installed on the same shaft and are installed on the base through a first bearing block. The other two sprockets are installed on the same shaft and are installed at the other end of the guide rail through a second bearing block. The sprockets are connected by a chain. The towing frame is located at the other end of the guide rail and is connected to the chain through a pin.

[0007] In the above technical solution, preferably, chain links are added to the chain, and the pin is connected to the chain link.

[0008] In the above technical solution, preferably, adjusting components for adjusting the tension degree of the chain are respectively provided at one ends of the two guide rails close to the base. The adjusting components include nuts and setscrews. The nuts are fixed on the guide rails, the setscrews are in threaded connection with the nuts and abut against the first bearing seat, and the guide rails are fixedly connected to the brackets through fasteners passing through the long round holes on the brackets.

[0009] In the above technical solution, preferably, polyurethane cushion plates are installed on the H-shaped steel between the two guide rails and on the base and below the upper part of the chain, so that the upper part of the chain is placed on the polyurethane cushion plates in a static state and does not disengage from the pins.

[0010] In the above technical solution, preferably, a groove is formed on the upper surface of one of the guide rails, and the groove is used for positioning with the wheels of the main die holder.

[0011] In the above technical solution, preferably, a proximity switch for detecting the position of the main die holder on the guide rail is provided on the side of the edge of the guide rail close to the base.

[0012] In the above technical solution, preferably, eyebolt screws are respectively arranged on the base and the guide rails for lifting the die holder pulling-out mechanism.

[0013] The advantages and positive effects of the present utility model are as follows:

[0014] 1. Compared with the traditional structure which needs to be transported separately during transportation, it is extremely easy to cause loss of parts, and secondary installation is required at the user site.

[0029] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "coupling", "connection", "installation", and "fastening" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0030] Please refer to Figures 1 to 6 , an embodiment of the present utility model provides a movable die holder pulling-out mechanism for a hot forging press, which includes a base 1, a motor reducer 6, a coupling 7, a small gear 8, a large gear 9, a sprocket 2, a chain 3, a guide rail 5, a bracket 14, and a towing bracket 13. The base 1, the guide rail 5, and the bracket 14 form an integral frame. The base 1 is located at one end of the two guide rails 5. The transmission mechanisms such as the motor reducer 6, the coupling 7, the small gear 8, and the large gear 9 are all arranged on the base 1;

[0031] The output end of the motor reducer 6 is connected to the small gear 8 through the coupling 7. The small gear 8 meshes with the large gear 9. Two sprockets 2 and the large gear 9 are installed on the same shaft and are installed on the base 1 through a bearing block 11-1. The other two sprockets 2 are installed on the same shaft and are installed at the other end of the guide rail 5 through a bearing block 11-2. The sprockets 2 are connected to each other through the chain 3. The towing bracket 13 is located at the other end of the guide rail 5, and the towing bracket 13 is connected to the chain 3 through a pin 15.

[0032] As a preferred embodiment, the standard chain 3 is modified. A link 16 is added to the chain 3, and the pin 15 is connected to the link 16 to ensure that the towing bracket 13 can be connected to the chain 3 through the pin 15.

[0033] As a preferred embodiment, adjusting components 12 for adjusting the tension of the chain 3 are respectively provided at one end of the two guide rails 5 close to the base 1. The adjusting components 12 include nuts and setscrews. The nuts are fixed on the guide rails 5. The setscrews are threadedly connected to the nuts and abut against the bearing block 11-1. The guide rail 5 is connected and fixed to the bracket 14 through fasteners passing through the long round holes on the bracket 14. When the fasteners are not tightened, rotating the setscrew can make the guide rail 5 move along the long round hole, and thus the tension of the chain 3 can be adjusted. When the guide rail 5 moves away from the base 1, the chain 3 can be tensioned.

[0034] As a preferred embodiment, since the guide rail 5 is relatively long, when in use, the motor may suddenly stop or maintenance may be required at an intermediate position. In the stationary state, the chain 3 will sag because it is not taut, resulting in the pin 15 disengaging from the link 16, and then it cannot be pulled out continuously. To avoid this phenomenon, polyurethane cushion plates 4 are installed on the H-shaped steel between the two guide rails 5 and at relevant positions on the base 1 and below the upper part of the chain, so that the upper part of the chain 3 rests on the polyurethane cushion plates 4 in the stationary state and will not disengage from the pin 15.

[0035] As a preferred embodiment, a groove 5-1 is formed on the upper surface of one of the guide rails 5, and the groove 5-1 is used for positioning with the wheels of the main die holder to prevent the main die holder from deviating from the guide rail 5 when being pulled out.

[0036] As a preferred embodiment, a proximity switch 17 for detecting the position of the main die holder on the guide rail 5 is provided on the edge of the guide rail 5 close to the base 1 to prevent the main die holder from rushing out of the guide rail 5 and causing damage.

[0037] As a preferred embodiment, lifting screws 10 are respectively provided on the base 1 and the guide rail 5 for lifting the die holder pulling mechanism.

[0038] The main structure of the movable die holder pulling mechanism of the hot die forging press of the present utility model includes: base 1, sprocket 2, chain 3, polyurethane cushion plate 4, guide rail 5, motor reducer 6, coupling 7, pinion 8, large gear 9, lifting screw 10, bearing block one 11-1, bearing block two 11-2, adjusting assembly 12, towing frame 13, bracket 14, pin 15, link 16, etc.

[0039] The specific use process of the present utility model is as follows:

[0040] 1. When it is necessary to replace or maintain the main die holder of the hot die forging press, first, the die holder pulling mechanism needs to be lifted to the front of the press, the guide rail 5 is fastened to the base 1 of the press through bolts, and at the same time, the towing frame 13 is fastened to the main die holder.

[0041] 2. After the preparation work is completed, first start the die holder jacking device of the press to jack out the wheels of the main die holder until they are flush with the surface of the guide rail 5. Start the motor reducer 6, the motor reducer 6 drives the pinion 8 to rotate through the coupling 7, and then drives the large gear 9 and the two sprockets 2 installed on the same shaft as the large gear 9 to rotate through gear meshing, and then drags the towing frame 13 and the main die holder through the chain 3 to pull the main die holder out of the press.

[0042] 3. After the replacement and maintenance are completed, the main die holder is sent into the press in the same way.

[0043] 4. After completing this series of operations, the guide rail 5 and the carriage 13 can be disconnected from the press and the main die holder, and the die holder pulling-out mechanism can be lifted away and placed in an empty area outside the working area. It will be lifted again when used next time.

[0044] Compared with the traditional structure that needs to be transported separately during transportation, it is extremely easy to cause parts loss, and secondary installation is required at the user's site. The mobile die holder pulling-out mechanism of the present utility model adopts an integrated structure. After installation, it can be sent to the user's site as a whole, and no secondary installation is required. It is convenient for installation and transportation and can be used after being powered on. When in use, the floor area is only 3 / 4 of that of the traditional structure, and the outer shape is a regular rectangle instead of the L shape of the traditional structure, greatly reducing the use space. Due to the low usage frequency, it can be lifted away after use and does not occupy the working area near the main machine. The phenomenon that the pin 15 connecting the carriage 13 and the link 16 is easily disconnected is effectively avoided. In addition, in terms of manufacturing cost, much less steel is used than the traditional structure, and there is no need to reserve an installation space in the foundation pit, which combines economy and practicability and conforms to the principle of cost reduction and efficiency improvement.

[0045] The above is only a preferred embodiment of the present utility model, and it does not impose any form of limitation on the present utility model. Any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present utility model are all within the scope of the technical solution of the present utility model.
