[0030] Example 1
[0031] Reference Figures 1-8 This is the first embodiment of the present invention. This embodiment provides a closed press, which includes a main body component 100, a frame 101, an upper die fixing plate 102, a lower die fixing plate 103, and a workpiece 104. The upper die fixing plate 102 is disposed on the frame 101, the lower die fixing plate 103 is located on one side of the upper die fixing plate 102, and the workpiece 104 is located on the lower die fixing plate 103. Through the cooperation between the upper die fixing plate 102 and the lower die fixing plate 103, pressure is applied to the workpiece 104, causing the workpiece 104 to undergo plastic deformation, and finally completing the processing. This is the prior art, and this solution will not be described in detail. Moreover, those skilled in the art can clearly understand the working principle.
[0032] The protective component 200 is mounted on the frame 101 and includes a protective member 201 located on the frame 101. The protective member 201 is used to effectively shield the front and rear areas of the press worktable, thereby preventing the workpiece from breaking and flying out during processing and causing injury to the operator. It also includes a trigger member 202 located on one side of the protective member 201. The trigger member 202 is used to trigger the unloading member 301 after processing and forming to assist in unloading the workpiece 104.
[0033] The trigger 202 includes a fixing block 202a and a locking block 202b. The fixing block 202a is located on one side of the protective member 201 and is fixed to the protective plate 201b. The fixing block 202a has a first moving groove 202a-1. The locking block 202b slides in the first moving groove 202a-1. The fixing block 202a provides stable support for the locking block 202b.
[0034] The unloading assembly 300 is located on the lower mold fixing plate 103 and includes two sets of unloading parts 301, which are symmetrically distributed on the lower mold fixing plate 103 to ensure that the workpiece 104 can be lifted smoothly. The unloading parts 301 can lift the processed workpiece 104 so that it protrudes from the surface of the lower mold fixing plate 103, making it easy to remove the workpiece 104.
[0035] The unloading component 301 includes a top plate 301a and a lifting block 301b. The lower mold fixing plate 103 has a lifting groove 103-1. The top plate 301a slides in the lifting groove 103-1. The top plate 301a is used to drive the workpiece 104 to move upward. The lifting block 301b is fixed to one side of the top plate 301a. The movement of the lifting block 301b will synchronously drive the top plate 301a to move. One end of the lifting block 301b protrudes from the side end face of the lower mold fixing plate 103.
[0036] In the initial state, the top end face of the top plate 301a will be on the same plane as the top end face of the lower mold fixing plate 103, and part of the workpiece 104 will be in contact with the top surface of the top plate 301a. When the lifting block 301b moves upward, the lifting block 301b will drive the top plate 301a to move upward along the lifting groove 103-1, and the top surface of the top plate 301a will protrude from the top end face of the lower mold fixing plate 103, thereby lifting the workpiece 104 and making it easier to remove the workpiece 104.
[0037] Example 2
[0038] Reference Figures 1-8 This is the second embodiment of the present invention, which is based on the previous embodiment.
[0039] Specifically, the protective component 201 includes a guide rail 201a, a protective plate 201b, and a mounting plate 201c. The guide rail 201a is fixed on the frame 101. There are two guide rails 201a, symmetrically distributed on the frame 101, which provide guidance for the movement of the protective plate 201b. The protective plate 201b slides on the guide rail 201a. A buffer pad 201f is fixed at the bottom of the guide rail 201a. The buffer pad 201f can deform and can buffer the protective plate 201b when it moves downward. The mounting plate 201c is fixed to one side of the protective plate 201b. The mounting plate 201c is used to connect the protective plate 201b to the upper mold fixing plate 102, so that the lifting and lowering of the upper mold fixing plate 102 can drive the upper mold fixing plate 102 and the protective plate 201b to move synchronously.
[0040] When the upper mold fixing plate 102 moves downward, the protective plate 201b will move synchronously. The protective plate 201b will first contact the buffer pad 201f. The upper mold fixing plate 102 continues to move downward and contact the workpiece 104 and continue to press down. The buffer pad 201f will continue to deform. At this time, the protective plate 201b will separate the upper mold fixing plate 102, the lower mold fixing plate 103 and the workpiece 104 from the outside of the frame 101 to prevent the workpiece 104 from breaking and jumping out, causing injury to the operator.
[0041] After processing is completed, the upper mold fixing plate 102 moves upward and away from the workpiece 104. At this time, the protective plate 201b will move upward, which will not affect the subsequent placement of the unprocessed workpiece 104.
[0042] A baffle 201g is also provided on the other side of the frame 101. The baffle 201g is connected to the frame 101 by bolts 201e. The baffle 201g will not move with the movement of the upper mold fixing plate 102. The baffle 201g can also separate the upper mold fixing plate 102, the lower mold fixing plate 103 and the workpiece 104 from the outside of the frame 101.
[0043] Specifically, an mounting block 201d is fixed on the upper mold fixing plate 102. Both the mounting block 201d and the mounting plate 201c have threaded grooves, and the two are connected by bolts 201e.
[0044] During installation, first place the protective plate 201b on the guide rail 201a, then adjust the height of the protective plate 201b, and use bolts 201e to connect the mounting block 201d to the mounting plate 201c, thereby completing the connection between the protective plate 201b and the upper mold fixing plate 102. Then connect the baffle 201g to the frame 101.
[0045] Specifically, a first spring 202c is fixed to one end of the locking block 202b, and the other end of the first spring 202c is fixed to the inner wall of the first moving groove 202a-1. The first spring 202c is set to apply a continuous pushing force to the locking block 202b, and the first spring 202c has a large elastic force.
[0046] Specifically, the locking block 202b has two inclined surfaces at one end, forming a tip. This tip allows the protective plate 201b to move downwards with the upper mold fixing plate 102, simultaneously causing the fixing block 202a to move the locking block 202b downwards. The inclined surface at the bottom of the locking block 202b will press against the lifting block 301b. Due to the large elastic force of the first spring 202c, the locking block 202b will not move temporarily, thus allowing the lifting block 301b to move downwards. When the lifting block 301b can no longer move, it will apply a pushing force to the inclined surface at the bottom of the locking block 202b, causing the locking block 202b to move away from the lifting block 301b along the first moving groove 202a-1. At this time, the protective plate 201b is still moving downwards, so the locking block 202b will not affect the downward movement of the protective plate 201b. After the locking block 202b separates from the lifting block 301b, the first spring 202c will push the locking block 202b back to its original position.
[0047] After processing is completed, the upper mold fixing plate 102 moves upward and away from the workpiece 104. The protective plate 201b moves upward with the upper mold fixing plate 102, and the fixing block 202a moves upward with the protective plate 201b, thereby driving the locking block 202b to move. The inclined surface of the upper part of the locking block 202b will first contact the lifting block 301b and squeeze the lifting block 301b, thereby causing the lifting block 301b to move upward. The top plate 301a will move synchronously and lift the workpiece 104. When the lifting block 301b can no longer move upward, the lifting block 301b will apply pressure to the inclined surface of the upper part of the locking block 202b, thereby compressing the first spring 202c. The locking block 202b will not affect the movement of the protective plate 201b. When the locking block 202b separates from the lifting block 301b, the first spring 202c will push the locking block 202b to reset.
[0048] Specifically, a second moving groove 103-2 is provided on the lower mold fixing plate 103. The lifting block 301b slides in the second moving groove 103-2. A second spring 301c is fixed to one end of the lifting block 301b, and the other end of the second spring 301c is fixed to the inner wall of the second moving groove 103-2. The second spring 301c is used to apply continuous pressure to the lifting block 301b and the top plate 301a. When the second spring 301c is in the relaxed state, the top end face of the top plate 301a is flush with the top end face of the lower mold fixing plate 103.
[0049] The elastic force of the second spring 301c is less than that of the first spring 202c. As a result, when the locking block 202b moves vertically, it will first apply a pushing force to the lifting block 301b, so that the lifting block 301b can be driven to move. Only when the movement of the lifting block 301b is restricted will the lifting block 301b apply a large pressure to the locking block 202b, thereby compressing the second spring 301c.
[0050] When the lifting block 301b is driven to move upward, the top end face of the second moving groove 103-2 will restrict the lifting block 301b from moving upward. When the two are in contact, the lifting block 301b cannot continue to move upward. When the lifting block 301b is driven to move downward, the second spring 301c will be compressed to its limit, after which the lifting block 301b cannot continue to move downward.
[0051] Example 3
[0052] Reference Figures 1-8 This is the third embodiment of the present invention, which is based on the first two embodiments.
[0053] Specifically, a sliding groove 103-3 is provided on the lower mold fixing plate 103, and a locking block 301d is provided in the sliding groove 103-3. The locking block 301d is used to restrict the movement of the lifting block 301b. A third spring 301e is fixed to one end of the locking block 301d, and the third spring 301e provides a stable thrust for the locking block 301d.
[0054] Specifically, a locking groove 301b-1 is provided in the lifting block 301b, and the locking block 301d can engage with the locking groove 301b-1. One end of the locking block 301d is inclined, and the shape of the locking groove 301b-1 corresponds to it.
[0055] The lifting block 301b is driven to move upward within the second moving groove 103-2. The locking groove 301b-1 moves along with the lifting block 301b. At this time, the inclined surface of the locking block 301d will first contact the end face of the lifting block 301b. The lifting block 301b presses against the inclined surface of the locking block 301d, causing the third spring 301e to compress. The locking block 301d moves into the sliding groove 103-3 without affecting the movement of the lifting block 301b. When the locking groove 301b-1 moves to a position coaxial with the locking block 301d, the two will engage. At this time, the right-angled surface of the locking block 301d and the right-angled surface of the locking groove 301b-1 are in contact, which will prevent the locking block 301d from separating from the locking groove 301b-1, thereby locking the position of the lifting block 301b and ensuring that the lifting block 301b will not move downward under the action of the second spring 301c, so that the workpiece 104 remains in a raised state.
[0056] A pull rope 301f is fixed on one side of the locking block 301d to unlock the lifting block 301b. After the workpiece 104 is removed after processing, the pull rope 301f is pulled, and the third spring 301e will be compressed, thereby separating the locking block 301d from the locking groove 301b-1. Under the action of the second spring 301c, the lifting block 301b and the top plate 301a move downward to the initial position.
[0057] Specifically, a punch 102-1 is movably connected to the upper mold fixing plate 102, and a die 103-4 is provided on the lower mold fixing plate 103.
[0058] Before processing, the workpiece 104 is plate-shaped. Through the cooperation of the punch 102-1 and the die 103-4, the workpiece 104 will be processed into the corresponding shape.
[0059] Specifically, the main component 100 also includes a control mechanism 105 and a lifting mechanism 106. The control mechanism 105 is fixed to one side of the frame 101, and the lifting mechanism 106 is fixed on the frame 101. During processing, the worker operates the control mechanism 105 to make the lifting mechanism 106 drive the upper mold fixing plate 102 to move up and down, thereby completing the processing.
[0060] When in use, after processing begins, as the upper mold fixing plate 102 moves downward, the protective plate 201b moves synchronously. The protective plate 201b will first contact the buffer pad 201f. As the upper mold fixing plate 102 continues to move downward, it contacts the workpiece 104 and continues to press down. The buffer pad 201f will continue to deform. At this time, the protective plate 201b separates the upper mold fixing plate 102, the lower mold fixing plate 103, and the workpiece 104 from the outside of the frame 101, preventing the workpiece 104 from breaking and jumping out, causing injury to the operator.
[0061] Simultaneously, as the protective plate 201b moves downward with the upper mold fixing plate 102, the fixing block 202a will synchronously drive the locking block 202b to move downward. The inclined surface at the bottom of the locking block 202b will press against the lifting block 301b, thereby causing the lifting block 301b to move downward. When the lifting block 301b can no longer move, the lifting block 301b will apply a pushing force to the inclined surface at the bottom of the locking block 202b, causing the locking block 202b to move away from the lifting block 301b along the first moving groove 202a-1. At this time, the protective plate 201b is still moving downward, so the locking block 202b will not affect the downward movement of the protective plate 201b. When the locking block 202b separates from the lifting block 301b, the first spring 202c will push the locking block 202b to reset. At this time, the locking block 202b will be located below the lifting block 301b.
[0062] After processing is completed, the upper mold fixing plate 102 moves upward and away from the workpiece 104. The protective plate 201b moves upward with the upper mold fixing plate 102, and the fixing block 202a moves upward with the protective plate 201b, thereby driving the locking block 202b to move. The inclined surface at the top of the locking block 202b first contacts the lifting block 301b and presses against it, causing the lifting block 301b to move upward. The top plate 301a moves synchronously, lifting the workpiece 104. The locking block 301d engages with the locking groove 301b-1, locking the position of the lifting block 301b and maintaining the workpiece 104 in a lifted state. The lifting block 301b applies pressure to the inclined surface at the top of the locking block 202b, from... When the first spring 202c is compressed, the locking block 202b will not affect the movement of the protective plate 201b. After the locking block 202b separates from the lifting block 301b, the first spring 202c will push the locking block 202b to reset. The locking block 202b continues to move upward with the protective plate 201b until it returns to its initial position. Then the workpiece 104 can be removed and the pull rope 301f can be pulled. The third spring 301e will be compressed, thereby separating the locking block 301d from the locking groove 301b-1. Under the action of the second spring 301c, the lifting block 301b and the top plate 301a move downward. The top end face of the top plate 301a is flush with the top end face of the lower mold fixing plate 103, which will not affect the next processing.
[0063] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
