Description

Technical Field

[0001] This utility model relates to the field of cleaning machine equipment manufacturing technology, specifically to a groove bending forming mold for a cleaning machine screen plate. Background Technology

[0002] The cleaning machine, also known as the powder cleaning machine, forms its grooves by stamping and bending them using a mold. Currently, when stamping the sidewalls of the grooves, the existing molds typically use a punch and die in combination. After forming, the sidewalls flip outwards under stress, requiring workers to use rubber hammers and a module to pound the sidewalls to ensure the angle between them and the bottom wall is less than 90°, resulting in low production efficiency for the grooves.

[0003] To address this, we propose an ejector-type pressure groove bending forming mold for the sieve plate of a sorting machine. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides an ejector-type pressing groove bending forming mold for a cleaning machine screen plate, which overcomes the deficiencies of existing technologies, has a reasonable design, is easy to form, and solves the technical problem of low production efficiency of existing pressing grooves.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A top-ejection type groove bending forming mold for a sorting machine screen plate, comprising an upper mold and a lower mold, characterized in that:

[0009] The upper die is elastically mounted with a punch and fixedly mounted with a drive block;

[0010] The lower mold is equipped with a concave mold, and sliders are slidably mounted on both sides of the lower mold on the concave mold. A first elastic element is provided between the slider and the concave mold. A mounting seat is mounted on the slider. The driving block and the slider are engaged by an inclined plane, and the slider slides towards the concave mold side against the action of the first elastic element. The first elastic element is used to drive the slider to slide away from the concave mold side. A forming roller is rotatably connected to the mounting seat. A forming notch is provided on the forming roller. The included angle of the forming notch is less than 90°. Under the action of the second elastic element, the bottom wall of the forming notch of the forming roller is raised upward and the side wall is turned outward.

[0011] The mounting base is elastically mounted vertically on the slider via a third elastic element. A lifting block is fixed to the side of the die adjacent to the mounting base. The mounting base and the lifting block are engaged by an inclined surface.

[0012] The drive block moves the slider laterally, and the lifting block is lifted by the inclined plane guiding the mounting base.

[0013] Furthermore, the first elastic element is a nitrogen spring, which is fixed to the lower mold and its output end abuts against the slider.

[0014] Furthermore, the second elastic element is a compression spring, and a pin is rotatably connected to the side of the forming roller away from the forming notch. A first compression spring is sleeved on the pin, and the two ends of the first compression spring abut against the forming roller and the mounting base, respectively.

[0015] Furthermore, the third elastic element is a tension spring, and the mounting base is elastically connected to the slider in a vertical direction via a guide post and the tension spring.

[0016] Furthermore, the punch is elastically connected to the lower part of the upper template via a fourth elastic element;

[0017] The fourth elastic element is the second compression spring, and the punch is elastically connected vertically to the lower part of the upper template via the second guide post and the second compression spring.

[0018] (III) Beneficial Effects

[0019] This utility model provides an ejector-type pressure groove bending forming mold for a sorting machine screen plate, which has the following advantages: During the downward mold closing process of the upper mold, the center part of the punch cooperates with the concave mold to press the bottom plate of the pressure groove, and its edge part cooperates with the notch of the forming roller to bend and form the side wall of the pressure groove. Since the notch angle of the forming roller is less than 90 degrees, during the upward mold opening process of the upper mold, the drive block moves upward first, while the punch remains in the state of being pressed with the concave mold. After the drive block moves upward, the slider, mounting seat and forming roller move away from the concave mold once under the action of the first elastic element. At the same time, the mounting seat falls after disengaging from the lifting block, so that the forming roller releases the restraint on the workpiece and the punch, and the punch can move upward. This utility model uses the punch to press down on the forming roller, which drives the forming roller to flip and bend the side wall of the pressure groove. At the same time, the angle between the flange and the bottom wall is less than 90 degrees, eliminating the need for subsequent hammering, making forming convenient and improving production efficiency.

[0038] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0039] See attached document Figure 1 , 2 A top-out type groove bending forming mold for a sorting machine screen plate, comprising an upper mold and a lower mold;

[0040] The upper mold is equipped with a punch 9 and a drive block 1, wherein the punch 9 is elastically connected to the upper template 10, and the drive block 1 is fixedly connected to the upper template 10.

[0041] The lower mold is equipped with a concave mold 3, and sliders 2 are slidably mounted on both sides of the lower mold located on the concave mold 3. The sliders 2 can move along... Figure 1The slider 2 slides horizontally in the left and right directions. A first elastic element is provided between the slider 2 and the die 3. The first elastic element is used to push the slider 2 away from the die 3. The driving block 1 and the slider 2 correspond one-to-one. The driving block 1 and the slider 2 are connected by inclined surfaces and make the slider 2 slide towards the die 3 against the action of the first elastic element. A mounting seat 4 is installed on the slider 2. The mounting seat 4 is rotatably connected to the forming roller 5. The forming roller 5 is provided with a forming notch. The included angle of the forming notch is less than 90°. Specifically, the journals on both sides of the forming roller 5 are rotatably connected to the mounting seat 4. A second elastic element is connected to the journal. The second elastic element acts on the forming roller 5 to make the bottom wall of the forming notch tilt upward and the side wall turn outward.

[0042] The mounting base 4 is vertically elastically mounted on the slider via a third elastic element. The mounting base 4 has stepped holes arranged vertically on the side facing the die 3. The stepped hole on the upper side is shallower than the stepped hole on the lower side. The inner wall of the upper stepped hole and the stepped hole is inclined. A lifting block 6 is fixed on the side of the die 3 adjacent to the mounting base 4. The mounting base 4 and the lifting block 6 are engaged by inclined surfaces, that is, the inclined surface at the end of the mounting base 4 engages with the inner wall of the stepped hole.

[0043] The drive block 1 drives the slider 2 to move laterally, and the mounting base 4 is guided by the inclined surface to overcome the effect of the third elastic element and lift up.

[0044] In this embodiment, the first elastic element is a nitrogen spring 11, which is supported on the lower template 13 of the lower mold by a spring support and its output end abuts against the slider 2.

[0045] In this embodiment, the mounting base 4 is provided with a mounting groove for mounting the forming roller 5, and the groove wall is an arc-shaped curved surface that matches the side wall of the forming roller. In some embodiments, end plates can be provided on both sides of the mounting groove to limit the forming roller 4. At the same time, journals can be provided at both ends of the forming roller 4, and the journals are rotatably supported on the end plates. In this case, the second elastic element is a torsion spring, which is sleeved on the journal and the two spring feet abut against the journal and the end plate, respectively. In other embodiments, the second elastic element is a compression spring. The forming roller 5 is rotatably connected to a pin on the side facing the mounting groove, that is, the side away from the forming notch. A through hole with a waist-shaped cross section is opened on the groove wall of the mounting groove. After the pin passes through the through hole, a nut can be threaded to prevent it from falling off. A first compression spring is sleeved on the pin, and the two ends of the first compression spring abut against the forming roller 5 and the mounting base 4, respectively. Correspondingly, the forming roller 5 and the mounting base 4 can each form an inner concave portion to accommodate the pin and the first compression spring.

[0046] In this embodiment, the third elastic element is a tension spring. The mounting base 4 is vertically elastically connected to the slider 2 via the first guide post 7 and the tension spring 8. The upper end of the first guide post 7 is threadedly fixed to the mounting base 4, and its lower end passes through the through hole of the guide post from top to bottom and is threadedly connected to a nut. The first tension spring 8 is sleeved on the outside of the first guide post 7, and the two ends of the first tension spring 8 are fixedly connected to the mounting base 4 and the slider 2 respectively. That is, when the mounting base 4 is separated from the lifting block 6, the mounting base moves downward under the action of the tension spring and its own weight, so that the forming roller releases the restraint on the workpiece and the punch.

[0047] In this embodiment, the punch 9 is elastically connected to the lower part of the upper template 10 through a fourth elastic element, which is a second compression spring 15. The punch 9 is elastically connected to the lower part of the upper template 10 vertically through the second guide post 14 and the second compression spring 15.

[0048] In this embodiment, the lower part of the slider 2 can be provided with a guide ridge protruding outward along the width direction. The lower template 13 is equipped with an inverted L-shaped limiting guide plate corresponding to the guide ridge. The guide ridge is slidably installed in the groove formed between the L-shaped limiting guide plate 12 and the lower template 13. The left end of the groove can be blocked by a limiting block. The limiting block cooperates with the guide ridge to limit the position of the slider 2.
