Description

Technical Field

[0001] The utility model belongs to the field of transfer devices, and particularly relates to a die precise alignment and pushing device for an elbow forming machine. Background Technique

[0002] In a pipeline system, a stainless steel elbow is a pipe fitting for changing the direction of a pipeline. Classified by angle, there are three conventional specifications of 45°, 90° and 180°, and in addition, according to engineering needs, there are also other non-normal angle elbows such as 60°; classified by diameter, there are different diameters; classified by wall thickness, there are different thicknesses; classified by material, the hardness varies greatly. Therefore, there are many specifications and models of stainless steel elbows, and different dies are required to produce different elbows.

[0003] Since different dies are required, die change is often needed. However, because the dies are very heavy, and after being pushed onto the working table of the forming machine, they need to be precisely centered with the slider of the forming machine. It is very difficult for the upper die to be centered and fixed with the slider. Usually, when replacing a new die, it is necessary to first use a forklift to raise the die to the same height as the upper working table of the forming machine, and then use a crane to hoist and translate the die onto the working table. However, this is not only time-consuming and laborious, but also the crane may not move along a very straight route when actually translating the die, and finally the die will be shifted obliquely. The die may not be precisely transferred to the position centered below the slider, and there will be a deviation between the centers of the two, so that it is not convenient to be centered and fixed with the slider. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the utility model is to overcome the current situation that when replacing a new elbow die, it is necessary to use a forklift to lift it to the height of the working table surface and then use a crane to translate it onto the working table, which is not only time-consuming and laborious, but also not easy to be precisely aligned during the crane translation.

[0005] To solve the above technical problem, the utility model provides a die precise alignment and pushing device for an elbow forming machine, which includes a movable push plate, a pushing assembly, a fixing frame and at least two roller assembly lines. The fixing frame is horizontally fixed on one of the vertical side walls of the forming machine body. The body of the pushing assembly is fixed on the fixing frame. The actuator of the pushing assembly is fixed to the push plate. The bottom plate of the push plate is provided with roller assembly lines. The length extension direction of the roller assembly lines is consistent with the moving direction of the push plate. Each roller assembly line includes at least two moving wheel groups arranged at intervals front and back. The wheels on the moving wheel groups roll on the fixing frame.

[0006] Preferably, it also includes a guide plate, the surface of the fixed frame is provided with a first guide groove corresponding to the linear position of the roller assembly, the guide plate is fixed on the upper surface of the workbench of the molding machine, and the guide plate is provided with a second guide groove connected with the first guide groove, the wheel width value of the moving wheel group, the width value of the first guide groove and the width value of the second guide groove are consistent, and the wheels of the moving wheel group can roll in the first guide groove and the second guide groove.

[0007] Preferably, the movable wheel group includes two connecting ears arranged on the left and right, a wheel axle and two wheels, the connecting ears are fixed to the bottom surface of the push plate, the two ends of the wheel axle are respectively inserted into the two connecting ears and fixed to the connecting ears, two wheels are simultaneously spaced apart on one wheel axle, and the wheels are rotatably connected to the wheel axle.

[0008] Preferably, the fixing frame is a frame structure, including a first connecting column, a second connecting column and a third connecting column, the two ends of the second connecting column are respectively fixed to one end of the first connecting column and one end of the third connecting column, the first connecting column and the third connecting column are parallel to each other, and the other end of the first connecting column and the other end of the third connecting column are both fixed to one of the vertical side walls of the molding machine.

[0009] Preferably, the outer side surface of the first connecting column is provided with a first groove extending along the length direction of the first connecting column, and the outer side surface of the third connecting column is provided with a second groove extending along the length direction of the third connecting column. A plurality of first reinforcing plates extending along the height direction and the depth direction of the first groove are arranged in the first groove at intervals, and a plurality of second reinforcing plates extending along the height direction and the depth direction of the second groove are arranged in the second groove at intervals.

[0010] The technical solution of the utility model has the following beneficial effects:

[0011] When the mold assembly needs to be replaced, the utility model uses a forklift to directly fork the mold assembly (i.e., the upper mold and the lower mold stacked up and down) from the mold vertical warehouse, and then fork it to the upper surface of the push plate. Then the push assembly is started, and its actuator pushes the push plate forward, so that the mold assembly on the push plate falls to the workbench of the molding machine in the direction of the front side of the push plate due to inertia, completing the transfer of the mold assembly from the push plate to the workbench. Since the forklift does not move in place, the only issue involved in forklift steering is the forklift's steering, so as long as the forklift position is adjusted once, there will be no need for alignment problems in the future, saving time and effort.

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 a direct connection or an indirect connection 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 circumstances.

[0021] In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0022] The present utility model provides a die precise alignment and pushing device for an elbow forming machine, which includes a push plate 1, a pushing component 2, a fixing frame 3, and at least two roller component lines 4. The fixing frame 3 is horizontally fixed on one of the vertical side walls of the forming machine body. The pushing component 2 is fixed on the fixing frame 3. The actuator of the pushing component 2 is fixed to the push plate 1. The roller component lines 4 are installed on the bottom plate of the push plate 1. The length extension direction of the roller component lines 4 is consistent with the moving direction of the push plate 1. Each roller component line 4 includes at least two moving wheel groups 41 arranged at intervals front and back. The wheels 413 on the moving wheel groups 41 roll on the fixing frame 3.

[0023] The using method of the present utility model: When it is necessary to replace the die assembly, use a forklift to directly pick up the die assembly (i.e., the upper die and the lower die stacked up and down) from the die storage library, and then fork it to the upper surface of the push plate 1. Then, the pushing component 2 is started, and its actuator pushes the push plate 1 forward, so that the die assembly on the push plate 1 falls onto the working table of the forming machine in the forward direction of the push plate due to inertia, completing the transfer of the die assembly from the push plate to the working table. Since the forklift remains stationary, only the problem of forklift turning is involved between the two steps of picking up the die and forking the die. Therefore, as long as the position of the forklift is adjusted once, there will be no subsequent alignment problem, which saves time and effort. Then, the lower die is locked on the working table, the slider of the forming machine descends, the upper die is locked on the slider, and the upper die is then driven by the slider to rise, so as to place the raw material (pipe) in the cavity of the lower die. When the raw material is placed in the cavity of the lower die, the upper die is driven by the slider to descend again, and the upper die and the lower die are combined together for product forming.

[0024] The pushing component 2 in the present utility model is actually an oil cylinder, and its actuator is the oil cylinder telescopic rod.

[0025] In order to ensure that the trajectory of the push plate 1 is a straight line when moving forward and there is no skew, the present utility model further includes a guide plate 5. A first guide groove 31 corresponding to the position of the roller assembly line 4 one by one is provided on the surface of the fixed frame 3. The guide plate 5 is fixed on the upper surface of the working table of the molding machine. A second guide groove 51 connected to the first guide groove 31 is provided on the guide plate 5. The width values of the wheels 413 of the moving wheel set 41, the width value of the first guide groove 31, and the width value of the second guide groove 51 are the same. The wheels 413 of the moving wheel set 41 can roll in the first guide groove 31 and the second guide groove 51. When the pushing assembly 2 drives the push plate 1 to move, the wheels 413 of the moving wheel set 41 first move in the first guide groove 31, so that the first guide groove 31 provides left and right limits for the wheels 413 of the moving wheel set 41, making the wheels 413 can only move in a straight line. Then the wheels 413 of the moving wheel set 41 will also move into the second guide groove 51, so that the second guide groove 51 provides left and right limits for the wheels 413 of the moving wheel set 41, making the wheels 413 can only move in a straight line.

[0026] Specifically, the moving wheel set 41 includes two connecting ears 411 arranged left and right, a wheel shaft 412, and two wheels 413. The connecting ears 411 are both fixed on the bottom surface of the push plate 1. The two ends of the wheel shaft 412 are respectively inserted into the two connecting ears 411 and fixed to the connecting ears 411. Two wheels 413 are sleeved on one wheel shaft 412 at intervals at the same time, and the wheels 413 are rotatably connected to the wheel shaft 412. The two connecting ears 411 play a role in fixing the wheel shaft 412 at the bottom of the push plate 1, and the wheel shaft 412 plays a role in supporting the two wheels 413. Bearings 414 are provided between the wheel shaft 412 and the wheels 413. The inner rings of the bearings 414 are sleeved and fixed on the wheel shaft 412, and the wheels 413 are sleeved and fixed on the outer rings of the bearings 414.

[0027] Since the mold assembly will increase the weight of the fixed frame 3 after being hoisted on the push plate 1, and if the fixed frame 3 itself is too heavy, it will have an adverse effect on the connection reliability between the fixed frame 3 and the molding machine. Therefore, the fixed frame 3 is set as a frame structure, including a first connecting column 32, a second connecting column 33, and a third connecting column 34. The two ends of the second connecting column 33 are respectively fixed to one end of the first connecting column 32 and one end of the third connecting column 34. The first connecting column 32 and the third connecting column 34 are parallel to each other. The other ends of the first connecting column 32 and the third connecting column 34 are both fixed to one of the vertical side walls of the molding machine.

[0028] In order to make the fixing frame 3 lighter, a first groove 321 extending along the length direction of the first connecting column 32 is provided on the outer side surface of the first connecting column 32, and a second groove 341 extending along the length direction of the third connecting column 34 is provided on the outer side surface of the third connecting column 34. However, to ensure the firmness of the first connecting column 32 and the second connecting column 33, a number of first reinforcing plates 322 extending along the height direction and the depth direction of the first groove 321 are spacedly arranged in the first groove 321, and a number of second reinforcing plates 342 extending along the height direction and the depth direction of the second groove 341 are spacedly arranged in the second groove 341.

[0029] Obviously, the above embodiments are merely examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or alterations can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or alterations derived therefrom still fall within the protection scope of the creation of the present utility model.
