Rigid side pushing mechanism

Abstract

The utility model discloses a rigid side pushing mechanism, which relates to the field of side face processing, and adopts the technical scheme that the rigid side pushing mechanism comprises an upper die holder and a lower die holder, the upper die holder is fixed on an upper machine table top of a punching machine, the lower die holder is fixed on a lower machine table top of the punching machine, and two sides of the top end of the upper die holder are connected with sliding blocks in a sliding manner; pressing blocks are installed on the front side and the rear side of the sliding block, and an inserting structure is arranged between the sliding block and the upper die base. When a punching machine drives an upper machine table face to move downwards, the effect is that when the punching machine drives a slotting tool to move up and down, due to the fact that a bevel edge A of the slotting tool makes contact with a bevel edge B in a slot, the sliding block and a pressing block can be driven to move back and forth, and therefore the punching machine can move up and down. Therefore, the actions of side pushing and mold opening are realized without using structures such as a suspension type side punching inclined wedge, a side sliding block and an air cylinder pushing block, and the use cost can be effectively reduced.

Description

Technical Field

[0001] The utility model relates to the field of side processing, and more specifically, to a rigid side thrust mechanism. Background Art

[0002] During the processing of some products, it is usually necessary to punch or cut off the side angles, which requires suspended side punch wedges, side slides, cylinder push blocks and other structures to achieve this. These structures are expensive, cumbersome to process, and require constant mold matching and debugging. The initial investment cost is also high, and they will be consumed as spare parts later.

[0003] Therefore, in order to solve the above technical problems, the present application proposes a rigid side thrust mechanism. Utility Model Content

[0004] In view of the deficiencies in the prior art, the present invention aims to provide a rigid side thrust mechanism.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a rigid side push mechanism, comprising an upper die base and a lower die base, wherein the upper die base is fixed on the upper table of the punch press, and the lower die base is fixed on the lower table of the punch press, a slider is slidably connected to both sides of the top of the upper die base, and pressure blocks are installed on the front and rear sides of the slider, and a plug-in structure is provided between the slider and the upper die base;

[0006] The plug-in structure includes raised portions fixed on both sides of the bottom end of the lower die base and a recessed portion arranged at the top end of the slider. When the punch press drives the upper machine table to move downward, the raised portion on the lower die base will be inserted into the recessed portion of the slider, and both the raised portion and the recessed portion are provided with matching inclined surfaces, thereby pushing the slider and the pressure block to move horizontally when the raised portion moves up and down.

[0007] Preferably, the protrusion is a plunger fixed on both sides of the bottom end of the upper mold base, and the recessed portion is a slot opened on the top of the slider; the middle two sides of the plunger are designed as bevels A, and the two sides of the inner side wall of the slot are also designed as bevels B that match the bevels A.

[0008] Preferably, the inserting portion of the inserting blade located below the oblique side A is an inserting portion, and the connecting portion located above the oblique side A is a connecting portion.

[0009] Preferably, an upper clamping plate connected to the connecting portion is fixedly connected to the bottom of the upper die base, and the connecting portion of the inserting knife is limited by the upper clamping plate, thereby ensuring the stability and accuracy of the inserting knife when it moves with the upper die base.

[0010] Preferably, the top end of the lower die base is fixedly connected to a lower pad that is slidably connected to the slider. The lower pad can provide a stable supporting surface for the slider, so that the slider remains stable during the sliding process.

[0011] Preferably, a screw hole is provided at the top of the connecting part, through slots for the connecting part to be inserted are provided on both sides of the inner portion of the upper clamping plate, and through holes for the screws to pass through are provided on both sides of the upper mold base above the through slots, so as to facilitate the disassembly and assembly of the insert knife.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. When the punch press drives the insert knife to move up and down, the bevel A of the insert knife and the bevel B in the slot contact each other, thereby driving the slider and the pressure block to move back and forth, thereby realizing the side pushing and mold opening action. This does not require the use of suspended side punch wedges, sliders, cylinder push blocks and other structures to achieve this, which can effectively reduce the cost of use, thereby solving the problem of the background technology that requires suspended side punch wedges, side sliders, cylinder push blocks and other structures to achieve this.

[0014] 2. The utility model inserts the connecting part of the inserting knife into the through slot on the upper clamping plate for positioning. At this time, the top of the connecting part contacts the bottom end of the upper die base. Then, the screw is passed through the through hole on the upper die base and then rotated clockwise to install it into the screw hole on the connecting part, thereby fixing the inserting knife to the upper clamping plate and the upper die base. Conversely, by removing the screw, the connecting part of the inserting knife can be pulled out of the through slot, completing the disassembly of the inserting knife. Disassembly and assembly are very simple, so that when the inserting knife is damaged due to friction, it is convenient to replace it.

[0015] 3. The bottom pad of the utility model can provide a stable support surface for the slider, so that the slider remains stable during the sliding process, reducing the shaking or deviation caused by unstable support, and also helps to disperse the pressure on the slider, thereby extending the service life of the slider and the lower die base;

[0016] 4. The utility model limits the connection part of the insert knife through the upper clamping plate, thereby ensuring the stability and accuracy of the insert knife when it moves with the upper die base. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] like Figure 1-6 As shown, the utility model provides a rigid side push mechanism, including an upper die base 1 and a lower die base 2, wherein sliders 3 are slidably connected to both sides of the top of the upper die base 1, and pressure blocks 4 are installed on the front and rear sides of the slider 3, and a plug-in structure 5 is provided between the slider 3 and the upper die base 1;

[0028] The plug-in structure 5 includes raised portions fixed on both sides of the bottom end of the lower die base 2 and a recessed portion provided at the top end of the slider 3. When the punch press drives the upper machine table to move downward, the raised portions on the lower die base 2 will be inserted into the recessed portion of the slider 3. The raised portions and the recessed portion are both provided with matching inclined surfaces, thereby pushing the slider 3 and the pressure block 4 to move laterally when the raised portions move up and down.

[0029] The raised portion is a plunger 501 fixed to both sides of the bottom end of the upper die base 1, and the recessed portion is a slot 502 provided at the top of the slider 3. Both sides of the middle portion of the plunger 501 are designed as bevels A5011, and both sides of the inner sidewall of the slot 502 are also designed as bevels B5021 that match the bevels A5011 (bevels A5011 and B5021 are the bevels mentioned above).

[0030] When in use, fix the upper die base 1 on the upper table of the punch press, and fix the lower die base 2 on the lower table of the punch press. Then place the product between the two slides 4. When the punch press is forced to move downward, the insert 501 of the upper die is first inserted into the slot 502 on the slide 3. After the insertion is completed, the bevel A5011 of the insert 501 contacts the bevel B5021 in the slot 502. When the punch press then drives the upper die base 1 and the insert 501 to move downward, the slide 3 slides to the middle under the action of the insert 501, thereby driving the slide 3 and the pressure block 4 to the middle at the same time. The parts move to realize the side push of the product. At the same time, since the bevel A5011 and the bevel B5021 are both set on both sides, when the punch press opens the mold upward, the upper mold base 1 is under the force of the punch press. Due to the mutual contact of the bevels, the insert knife 501 will also drive the slider 3 and the pressure block 4 to move to both ends to realize mold opening, which is convenient for taking out the product until the bevel A5011 and the bevel B5021 are separated from each other. When the operation is repeated, the above steps can be followed to cycle the operation. It should be noted that the slider 3 and the insert knife 501 of the utility model are made of rigid materials and are not easily deformed when subjected to force.

[0031] Furthermore, the inserting portion 5012 of the inserting knife 501 is located below the oblique side A5011, and the connecting portion 5013 is located above the oblique side A5011. The bottom of the upper mold base 1 is fixedly connected to an upper clamping plate 6 connected to the connecting portion 5013. The upper clamping plate 6 limits the connecting portion 5013 of the inserting knife 501, thereby ensuring the stability and accuracy of the inserting knife 501 when moving with the upper mold base 1, and preventing the inserting knife 501 from loosening or displacement during operation. The following is the specific structure of the connection of the inserting knife 501: a screw hole 8 is provided at the top of the connecting portion 5013, and through grooves 9 for inserting the connecting portion 5013 are provided on both sides of the upper clamping plate 6. Through holes 10 for screws to pass through are provided on both sides of the upper mold base 1 above the through grooves 9.

[0032] During installation, the connecting portion 5013 on the insert blade 501 is inserted into the through slot 9 on the upper clamping plate 6 for limiting. At this time, the top end of the connecting portion 5013 contacts the bottom end of the upper mold base 1. Then, the screw is passed through the through hole 10 on the upper mold base 1 and then rotated clockwise to install it into the screw hole 8 on the connecting portion 5013, thereby fixing the insert blade 501 to the upper clamping plate 6 and the upper mold base 1. Conversely, the screw can be removed to pull the connecting portion 5013 of the insert blade 501 out of the through slot 9, completing the disassembly of the insert blade 501. Disassembly and assembly are very simple, so that when the insert blade 501 is damaged due to friction, it is convenient to replace it.

[0033] Moreover, the top end of the lower die base 2 is fixedly connected to the lower pad 7 which is slidably connected to the slider 3. The lower pad 7 can provide a stable support surface for the slider 3, so that the slider 3 remains stable during the sliding process, reducing the shaking or deviation caused by unstable support, and also helping to disperse the pressure on the slider 3, thereby extending the service life of the slider 3 and the lower die base 2.

[0034] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Any ordinary technician in this industry can smoothly implement the present invention as shown in the drawings and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with this profession without departing from the scope of the technical solution of the present invention using the technical content disclosed above are all equivalent embodiments of the present invention. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the present invention are still within the scope of protection of the technical solution of the present invention.
