Description

Technical Field

[0001] This utility model relates to the field of automated powder molding production technology, specifically to a positioning and pushing device for powder pressing products. Background Technology

[0002] Currently, in the powder molding industry, certain block-shaped parts required by equipment are typically formed in one step using a four-column hydraulic press, resulting in a product structure that is square on the outside and round on the inside. The existing production process is as follows: after the material is proportioned, it is fed and pressed into shape using a four-column hydraulic press. The formed products are then ejected from the material box and manually stacked and palletized.

[0003] In recent years, with the advancement of automation upgrades, six-axis robots have been introduced into the workshop at the back end of the pressing process to achieve automated product gripping, assembly, and palletizing. However, the following problems still exist in the material box pushing process: (1) The pushed products are prone to tilting or shifting, resulting in inaccurate positioning; (2) The product is not pushed properly, and the robot cannot pick it up successfully; (3) The existing pushing tooling structure is not strong enough and is prone to deformation or even damage during operation.

[0004] These problems directly cause the robot to fail to grasp objects at the preset points, resulting in frequent "collisions," equipment damage, downtime, and decreased production efficiency.

[0005] In addition, existing equipment cannot detect in real time whether the core rod has reset. When the core rod has not fallen, the pushing device may interfere with it, further increasing the operational risk. Since the equipment outlet height is about 1.8 meters, it is difficult for personnel to judge the status of the core rod visually, making the reset operation inconvenient, resulting in equipment damage and production disruption.

[0006] Therefore, there is an urgent need for a push device with a reasonable structure, accurate positioning, and stable operation to solve the problems existing in the current technology. Utility Model Content

[0007] The purpose of this invention is to provide a positioning and pushing device for powder pressing products, which at least partially solves one of the technical problems in the related technology.

[0008] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A positioning and pushing device for powder-pressed products includes a fixed frame, a movable frame, and a guide frame arranged sequentially from back to front. The frame includes a fixed plate, which is fixedly connected to the material box and moves synchronously with the material box; a fixed arm extending forward is fixed on the fixed plate; The movable frame includes a movable plate located in front of the fixed plate. A movable arm extending backward is fixed on the movable plate. The movable arm and the fixed arm are connected at their overlapping positions by a spacing adjustment mechanism, which adjusts the front-to-back distance between the movable frame and the fixed frame. The guide frame includes two baffles arranged opposite each other on the left and right sides. The baffles are fixed to the front side of the movable plate, and a positioning channel is formed between the two baffles. The size of the positioning channel is adapted to the external dimensions of the product.

[0009] Furthermore, there are two fixed arms symmetrically arranged on the left and right, and two movable arms are also symmetrically arranged on the left and right.

[0010] Furthermore, the spacing adjustment mechanism includes an adjustment groove extending along the front-back direction on the movable arm, and multiple adjustment holes arranged along the front-back direction at positions corresponding to the adjustment groove on the fixed arm. Adjustment screws pass through the adjustment holes and the adjustment groove to achieve a fixed connection between the movable arm and the fixed arm.

[0011] Furthermore, the adjustment slots are provided in two parallel positions, one above the other; adjustment holes are provided on the fixed arm at positions corresponding to the two adjustment slots.

[0012] Furthermore, the position on the movable plate corresponding to the positioning channel is set as an opening, and a protective plate is detachably fixed at the opening, with the height of the protective plate being higher than that of the movable plate.

[0013] Furthermore, vertical slots are provided on both sides of the opening, and the protective plate is inserted into the slots from top to bottom on both sides. A fixing screw is provided at the rear side plate of the slot, and the end of the fixing screw abuts against the protective plate.

[0014] Furthermore, the protective plate is made of a brittle material.

[0015] Furthermore, the protective panel is made of acrylic sheet.

[0016] Furthermore, the fixing plate is provided with fixing holes, and locking screws passing through the fixing holes are used to fix and connect the plate to the material box.

[0017] Furthermore, the fixing hole is an elongated hole extending in the left-right direction.

[0018] The beneficial effects of this utility model are: This invention can accurately and stably push powdered products to a predetermined position after they have been pressed and formed, ensuring that the robot can smoothly grasp them, thereby improving production efficiency, reducing labor intensity, and enhancing the reliability and safety of equipment operation. Compared with the prior art, it has the following advantages: (1) High positioning accuracy: The positioning channel ensures stable product pushing, avoids skew or deviation, and improves the success rate of robot gripping.

[0019] (2) Low maintenance cost: The protective plate can break first upon impact, avoiding overall damage. Only the protective plate needs to be replaced, which is convenient and reduces material waste and maintenance costs.

[0020] (3) Wide range of applications: The distance between the movable frame and the fixed frame can be adjusted by the distance adjustment mechanism, thereby realizing the adjustment of the pushing distance to adapt to the size of different machines or products and ensure accurate pushing point.

[0021] (4) Reliable structure: The fixed frame moves synchronously with the material box to avoid products not being in place and to ensure pushing accuracy.

[0022] (5) High durability: The overall structure is stable, avoiding the problem of easy deformation of traditional push tooling and extending service life.

[0023] (6) High production efficiency: Reduce manual intervention, shorten production cycle, reduce labor intensity, and improve production safety and consistency.

[0025] Figure 1 This is a schematic diagram of the structure of this utility model.

[0026] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the present invention. To better illustrate this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings. Detailed Implementation

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0028] like Figure 1 As shown, this embodiment provides a positioning and pushing device for powder-pressed products, including a fixed frame, a movable frame, and a guide frame arranged sequentially from back to front.

[0029] The fixing frame includes a fixing plate 9, and fixing arms 4 extending forward are fixed at the left and right ends of the fixing plate 9, respectively.

[0030] The fixing plate 9 has fixing holes 5, through which locking screws pass to and are fixedly connected to the material box. This allows the positioning and pushing device to move synchronously with the material box, maintaining consistent action. The material box is an existing component of the production line, its function being to fill the mold cavity of the press with material.

[0031] In this embodiment, the fixing hole 5 is an elongated hole extending in the left and right direction, which facilitates the adjustment of the installation position of the fixing frame and the material box.

[0032] The movable frame includes a movable plate 10, which is located in front of the fixed plate. Movable arms 11 extending backward are fixed at both ends of the movable plate 10. The movable arm 11 on the same side is connected to the fixed arm 4 at the overlapping position by a spacing adjustment mechanism. The spacing adjustment mechanism is used to adjust the front-to-back distance between the movable frame and the fixed frame.

[0033] Specifically, the spacing adjustment mechanism includes an adjustment groove 3 extending along the front-back direction on the movable arm 11, and multiple adjustment holes arranged along the front-back direction at positions corresponding to the adjustment groove 3 on the fixed arm 4. The adjustment screw 6 passes through the adjustment holes and the adjustment groove 3 to achieve a fixed connection between the movable arm 11 and the fixed arm 4.

[0034] When adjusting the front-to-back distance between the movable frame and the fixed frame, loosen the adjusting screw 6 and then move the movable frame forward or backward. After adjusting the position, tighten the adjusting screw 6. In this way, by adjusting the front-to-back distance between the movable frame and the fixed frame, the pushing distance can be adjusted to adapt to the size of different machines or products and ensure accurate pushing points.

[0035] To ensure a stable connection between the movable arm 11 and the fixed arm 4, two adjustment slots 3 are provided, which are arranged parallel to each other vertically. Adjustment holes are provided on the fixed arm 4 at positions corresponding to the two adjustment slots 3.

[0036] In this embodiment, the fixed frame and the movable frame are made of metal to enhance the reliability and durability of the connection. Furthermore, the addition of stiffening ribs 12 strengthens the design, ensuring stability and durability during long-term operation.

[0037] The guide frame includes two baffles 8 arranged opposite each other on the left and right sides. The baffles 8 are fixed to the front side of the movable plate 10, and a positioning channel is formed between the two baffles 8. In this embodiment, the product 1 is a block-shaped product with a square outer shape and a round inner shape. The size of the positioning channel is set according to the outer dimensions of the product 1. It is used to limit and guide the product during the pushing process to prevent skew or deviation and ensure that the product enters the area that the robot can grasp.

[0038] An opening is provided on the movable plate 10 at the position corresponding to the positioning channel. A protective plate 2 is detachably fixed at the opening, and the height of the protective plate 2 is higher than that of the movable plate 10.

[0039] To facilitate easy replacement of the protective plate, this embodiment has vertical slots on both sides of the opening. The protective plate 2 is inserted into the slots from top to bottom on both sides, and a fixing screw 7 is provided through the rear side plate of the slot. The end of the fixing screw 7 abuts against the protective plate 2.

[0040] The protective plate 2 is made of a brittle material. In this embodiment, the protective plate is made of acrylic sheet.

[0041] Protective plate 2 is installed at locations where the device may collide with the core rod. In the event of an abnormality, protective plate 2 can break first, preventing deformation of the overall structure. Replacement is simple; just loosen the fixing screw 7.

[0042] The working principle of this utility model is as follows: The press fills the mold cavity with material through the material box. After pressing, demolding and other process steps, the material box moves the entire positioning and pushing device to the front of the press, pushing product 1 forward to a fixed position (which has been adjusted). Then, it is picked up and stacked by a six-axis robot.

[0043] The positioning and pushing device of this utility model has a reasonable structure and complete functions. It can effectively solve the problems of product pushing skew, incomplete positioning and easy deformation of tooling in the prior art, and achieve stable pushing and accurate positioning, which has significant practical value.
