Description

TECHNICAL FIELD

[0001] The utility model relates to annular workpiece flattening field especially suitable for annular workpiece's press into flattening device. BACKGROUND

[0002] Annular workpiece refers to the workpiece with annular or circular cross section, and such workpiece is very common in industrial production, especially in the field of manufacturing standard parts, automobile parts, beverage production, etc. Annular workpiece can be made of various materials, including but not limited to plastic, PTFE, etc. The production of annular workpiece usually includes raw material selection, mould pressing, sintering, turning, shaping and other process flows.

[0003] In the existing processing process, sometimes the axial end face of the annular workpiece needs to be turned to ensure the flatness of the end face and the perpendicularity to the axial direction, but when turning the annular workpiece, in order to facilitate the taking of the annular workpiece and to make the annular workpiece have certain supportability during turning, so that its shape is stable and convenient for turning, a certain supporting structure will be inserted into the inside of the annular workpiece, such as a cylindrical piece matched with the annular workpiece, etc.

[0004] Therefore, it is usually necessary to manually or by using corresponding tools to set the above-mentioned annular workpiece into the supporting structure. However, since the annular workpiece is made of non-metallic material, it is easy to deform when the annular workpiece is set due to uneven stress, so it is often difficult to ensure the consistency of the end face of the annular workpiece relative to the axial depth of the supporting structure, that is, the end face of the annular workpiece and the axial direction of the supporting structure are inclined to each other, which easily leads to difficulty in positioning during turning, and the annular workpiece cannot be turned at one time, and often needs to be turned several times to meet the requirements, thereby causing material and time consumption during turning, which is not conducive to improving production efficiency. SUMMARY

[0005] Therefore, the utility model provides a kind of press into flattening device suitable for annular workpiece to solve the above-mentioned problems.

[0018] The specific embodiments of this utility model will be described in further detail below. It should be understood that the description of this utility model herein is not intended to limit the scope of protection of this utility model.

[0019] like Figures 1 to 3 The diagram shows a structural schematic of a pressing and leveling device for annular workpieces provided by this utility model. The pressing and leveling device for annular workpieces includes a lower template assembly 10, at least two guide post assemblies 20 disposed on the lower template assembly 10, an upper template assembly 30 movably sleeved on the guide post assemblies 20, and a support cylinder 40 for supporting the annular workpiece 50. It is conceivable that the pressing and leveling device for annular workpieces should also include other functional components, such as electrical connection components, fastening components, and drive motors, all of which are prior art known to those skilled in the art and will not be described in detail here.

[0020] The lower template assembly 10 includes a lower template 11 and two lower template supports 12 respectively disposed on both sides of the lower template 11.

[0021] The lower mold plate 11 comprises a lower mold plate body 111, two support piece installation grooves 112 respectively arranged on both sides of the lower mold plate body 111, and a plurality of guide pillar installation holes 113 arranged on the lower mold plate body 111.

[0022] The lower mold plate body 111 can be a square structure, which can be cut from a plate. The lower mold plate body 111 is used to support the support barrel 40 and cooperate with the upper mold plate assembly 30 during operation of the flattening device to press the annular workpiece 50 to be turned onto the support barrel 40.

[0023] The support piece installation groove 112 is used to install the lower mold plate support piece 12. Two support piece installation grooves 112 are symmetrically arranged along the length direction of the lower mold plate body 111 on both sides of the lower mold plate body 111 and are centrally arranged along the width direction of the lower mold plate body 111. The support piece installation groove 112 can have a U-shaped structure to facilitate assembly of the lower mold plate support piece 12 and the lower mold plate body 111.

[0024] The guide pillar installation hole 113 is used to install the guide pillar assembly 20, and the size and size thereof are adapted to the size of the guide pillar assembly 20. According to the number of the guide pillar assembly 20, a plurality of guide pillar installation holes 113 are arranged on the lower mold plate body 111.

[0025] The lower mold plate support piece 12 has a U-shaped structure, and when assembled, the U-shaped openings of two lower mold plate support pieces 12 are arranged face to face, and both sides of the lower mold plate body 111 are arranged in the U-shaped openings. An installation screw hole is arranged on the side of the lower mold plate support piece 12 facing the ground, and the position of the installation screw hole corresponds to the position of the support piece installation groove 112. When assembled, the connecting stud is inserted into the installation screw hole and the support piece installation groove 112, and a nut is used to fix it. At the same time, in order to ensure the flatness of the lower mold plate body 111 and thus the flatness of the annular workpiece 50 when it is fitted, the lower mold plate body 111 can be attached to the side away from the ground of the lower mold plate support piece 12 by adjusting the fixing nut. In addition, since the lower mold plate support piece 12 has a U-shaped structure, the position of the lower mold plate 11 can be adjusted to adjust the distance between the lower mold plate 11 and the upper mold plate 31 described below, so as to adapt to the pressing of annular workpieces 50 of different specifications.

[0026] The guide pillar assembly 20 is used to guide the up-and-down sliding of the upper die plate assembly 30, so as to extrude the annular workpiece 50, so as to press the annular workpiece 50 into the support barrel 40. The guide pillar assembly 20 is arranged in pairs and symmetrically on the lower die plate body 111, so as to ensure the stability and stroke consistency when the upper die plate assembly 30 is pressed down. In the embodiment, four guide pillar assemblies 20 are arranged, which are symmetrically arranged on both sides of the lower die plate body 111, so as to ensure the balance and centration when the upper die plate assembly 30 is opened and closed. Each guide pillar assembly 20 comprises a guide pillar 21 fixedly arranged on the lower die plate 11, a lower pressing height limiting sleeve 22 sleeved on the guide pillar 21, at least two guide pillar fixing nuts 23 for fixedly mounting the guide pillar 21, and a die plate anti-disengagement piece 24 arranged at an end of the guide pillar 21 away from the lower die plate 10.

[0027] The guide pillar 21 is used to guide the up-and-down movement of the upper die plate assembly 30, so as to ensure the operation stability and accuracy of the upper die plate assembly 30. The guide pillar 21 is usually composed of an inner guide pillar and a guide sleeve sleeved outside the inner guide pillar, wherein the inner guide pillar mainly plays a guiding and positioning role, and the guide sleeve is used to prevent the upper die plate assembly 30 from directly contacting and rubbing with the inner guide pillar during the up-and-down sliding process, thereby affecting the service life of the guide pillar 21. The guide pillar 21 is usually made of bearing steel, die steel and other materials with good wear resistance and high strength. The guide pillar 21 itself is a prior art known to those skilled in the art, and will not be described in detail here. Threaded connections are arranged at both ends of the guide pillar 21, so as to facilitate the installation of the guide pillar assembly 20.

[0028] The lower pressing height limiting sleeve 22 is sleeved on the guide pillar 21 and located between the lower die plate assembly 10 and the upper die plate assembly 30, and is used to limit the pressing height of the upper die plate assembly 30, so as to ensure that the pressing height of the upper die plate assembly 30 can be kept consistent each time, thereby making the height of the annular workpiece 50 sleeved into the support barrel 40 consistent, thereby facilitating the turning positioning. An adjusting nut is arranged at an end of the lower pressing height limiting sleeve 22 towards the lower die plate 11, and the height of the lower pressing height limiting sleeve 22 can be adjusted by adjusting the position of the adjusting nut, so that the upper die plate assembly 30 can meet different pressing height requirements.

[0029] The guide pillar fixing nut 23 is matched with the guide pillar 21 and is used to fix the guide pillar 21 on the lower die plate 11. The guide pillar fixing nut 23 can be a hexagonal nut. When the guide pillar 21 is installed on the lower die plate 11, one end of the guide pillar 21 is inserted into the guide pillar mounting hole 113, and at least one guide pillar fixing nut 23 is arranged on both sides of the guide pillar mounting hole 113. The two guide pillar fixing nuts 23 are rotated towards each other along the thread structure arranged on the guide pillar 21 until the guide pillar 21 is completely fixed on the lower die plate 11.

[0030] The die plate anti-disengagement piece 24 can be a square washer and is fixedly arranged at one end of the guide pillar 21 away from the lower die plate 11. It is used to prevent the upper die plate assembly 30 from disengaging from the guide pillar 21. It can be understood that the diameter of the end of the guide pillar 21 on which the die plate anti-disengagement piece 24 is arranged can be smaller than the diameter of the main body of the guide pillar 21, thereby forming a stepped structure on the guide pillar 21 to facilitate the installation of the die plate anti-disengagement piece 24. A nut can be used in combination with the thread structure to fix the die plate anti-disengagement piece 24 on the guide pillar 21.

[0031] The upper die plate assembly 30 includes an upper die plate 31 movably sleeved on the guide pillar 21 and a die handle 32 fixedly arranged on the upper die plate 31.

[0032] A plurality of mounting holes corresponding to the guide pillar 21 and the die handle 32 are arranged on the upper die plate 31. The upper die plate 31 is movably sleeved on the guide pillar 21 through the mounting holes and slides up and down along the guide pillar 21 parallel to the lower die plate 11 under the drive of an external motor, thereby pressing the annular workpiece 50 and the support cylinder 40, so that the annular workpiece 50 is sleeved on the support cylinder 40. Due to the presence of the guide pillar 21 of the guide pillar assembly 20, the perpendicularity of the guide pillar 21 and the coaxiality of the mounting holes on the upper die plate 31 and the guide pillar 21 can be ensured, thereby achieving high parallelism between the upper die plate 31 and the lower die plate 11, and high coaxiality between the pressed annular workpiece 50 and the support cylinder 40, and achieving the purpose of flattening.

[0033] The die handle 32 includes a mounting portion 321 fixedly connected to the upper die plate 31 and a connecting handle 322 fixedly connected to the mounting portion 321.

[0034] The mounting portion 321 can be a disc structure and is fixedly connected to the upper die plate 31 by a fastener such as a hexagonal screw, thereby fixing the die handle 32 on the upper die plate 31.

[0035] One end of the connecting handle 322 is fixedly connected with the mounting portion 321, and the other end is fixedly connected with an external driving device (not shown in the figure), so that the upper die plate 31 is driven to move along the guide column 21 under the driving of the driving device. The driving device can be a motor, a cylinder or other device capable of providing power to drive the upper die plate 31 to move, which is a prior art known to those skilled in the art and will not be described here.

[0036] The support cylinder 40 is directly placed on the lower die plate 11, which can be selected in different specifications according to actual needs. The support cylinder 40 is matched in size with the annular workpiece 50 to be processed. Before turning the annular workpiece 50, it is inserted into the annular workpiece 50, so as to support the annular workpiece 50, facilitate turning of the annular workpiece 50, and avoid that the annular workpiece 50 is easily crushed during processing, is not easy to take, and is easily deformed during turning, causing that the annular workpiece 50 cannot be turned or is turned crooked. Before turning, the annular workpiece 50 to be turned is sleeved on one end of the support cylinder 40 and placed on the lower die plate 11, and then the upper die plate 31 is driven to slide downward along the guide column 21 to press the annular workpiece 50 and the support cylinder 40, so that the annular workpiece 50 is sleeved on the support cylinder 40 and flush with the support cylinder 40, thereby facilitating positioning of the next turning process, so that the annular workpiece 50 can be accurately turned in one stroke, and time and effort are saved by avoiding repeated turning, and the machining waste caused by inaccurate turning is greatly avoided.

[0037] Compared with the prior art, the pressing and flattening device suitable for the annular workpiece comprises the lower die plate assembly 10, the guide column assembly 20 fixedly arranged in pairs on the lower die plate assembly 10, the upper die plate assembly 30 movably sleeved on the guide column assembly 20, and the support cylinder 40. Before turning, the annular workpiece 50 to be turned is sleeved on one end of the support cylinder 40 and placed on the lower die plate 11, and then the upper die plate assembly 30 is driven to slide downward along the guide column 21 to press the annular workpiece 50 and the support cylinder 40, so that the annular workpiece 50 is further firmly sleeved on the support cylinder 40 and flush with the support cylinder 40, thereby facilitating positioning of the next turning process, so that the annular workpiece 50 can be accurately turned in one stroke, and time and effort are saved by avoiding repeated turning, and the machining waste caused by inaccurate turning is greatly avoided.

[0038] The above is only a preferred embodiment of the present application, and is not used to limit the protection scope of the present application. Any modification, equivalent replacement or improvement within the spirit of the present application is covered within the protection scope of the present application.
