Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, and in particular to a combined horizontal ruler punching die. Background Technology

[0002] A spirit level is a measuring instrument that uses the principle of a level liquid surface to directly display angular displacement with a bubble level, and measures the degree of deviation of the measured surface from its horizontal, vertical, and tilt positions.

[0003] A spirit level consists of an outer ruler body, which is typically made of metal. In existing technology, the ruler body is usually manufactured by using independently arranged stamping dies to punch out the required openings and opening structures at different locations on the ruler body. This results in low processing efficiency and requires more stamping drive equipment to drive the stamping dies, leading to increased equipment investment. Furthermore, the positional accuracy of the openings and holes machined on the ruler body does not meet design requirements.

[0004] Therefore, how to provide a combined horizontal ruler punching die with a simpler and more reasonable structural design that can improve processing efficiency, reduce equipment investment, and better improve the accuracy of the opening and opening position on the ruler body has become a technical problem to be solved by those skilled in the art. Summary of the Invention

[0005] In view of the above-mentioned defects of the prior art, the technical problem to be solved by this utility model is how to provide a combined horizontal ruler punching mold with a simpler and more reasonable structural design, which can improve processing efficiency, reduce equipment investment, and better improve the accuracy of the opening and opening position on the ruler body.

[0006] To achieve the above objectives, this utility model provides a combined horizontal ruler punching die, characterized in that: it includes an upper combined die frame and a lower combined die frame; multiple stamping dies are arranged at intervals between the upper and lower combined die frames along the longitudinal direction; the stamping dies include an upper punch part structure and a lower die part structure; the punch part structure includes an upper punch mounting plate mounted on the upper combined die frame, and the die part structure includes a lower die mounting plate mounted on the lower combined die frame; the punch part structure also includes a lower punch, and the die part structure also includes an upper die; and a vertical guide part structure is provided between the punch part structure and the die part structure; the upper combined die frame has a die handle structure at its upper end for connecting to a stamping drive device, and is able to drive the upper combined die frame to move towards the lower combined die frame, and to perform punching processing on the ruler body on the die.

[0007] Thus, in the aforementioned combined horizontal ruler punching die, multiple stamping dies can be arranged between the upper and lower combined die frames according to processing requirements, enabling multiple holes on the ruler to be punched in one operation. Furthermore, the spacing between the stamping dies can be adjusted to accommodate different hole spacing requirements for rulers of different specifications. Simultaneously, it saves on investment in stamping drive equipment, reducing equipment costs. Secondly, the same equipment and the same stamping operation can complete openings and holes at different positions on the ruler, improving the positional accuracy between openings and holes.

[0008] As an optimization, two stamping dies are arranged at intervals between the upper and lower combined mold bases along the longitudinal direction.

[0009] This arrangement of two stamping dies results in a simpler and more rational structural layout.

[0010] As an optimization, a position sensor is installed on one of the outermost die mounting plates. A sensing contact block is installed on the sensing rod end of the position sensor, so that one end face of the ruler can abut against and support the end face of the sensing contact block.

[0011] In this way, by setting up a position sensor and a sensing contact block, one end face of the ruler can be supported against the end face of the sensing contact block, thereby detecting whether the ruler is placed in place and improving the quality of processing.

[0012] As an optimization, a positioning support with a rectangular block structure is provided on one of the outermost concave dies.

[0013] In this way, by setting a positioning base, the end face of the ruler can be positioned more effectively.

[0014] As an optimization, the lower mold base includes a lower mold base plate, on which a rectangular blanking port is provided at a position opposite to the die cavity. The blanking port extends through the thickness direction of the lower mold base plate. At each end of the blanking port, a blanking guide plate is connected and inclined downwards towards the inside, and a blanking outlet is formed between the two blanking guide plates.

[0015] In this way, the lower die plate of the lower combination die set is provided with a blanking port, and a blanking guide plate is installed in the blanking port to facilitate smooth blanking when using large-pitch sub-die (stamping die).

[0016] As an optimization, a longitudinally penetrating lower mounting groove is provided on the upper surface of the lower mold frame plate, and the corresponding die mounting plate is arranged in the lower mounting groove. The lower ends of the two sides of the die mounting plate protrude outward to form lower mounting strips, and the two outer sides of the lower mounting strips are respectively supported against the side wall of the lower mounting groove. A lower pressure strip is provided on the lower mold frame plate and corresponding to the lower mounting strip. The lower pressure strip is connected to the lower mold frame plate by screws, and the lower pressure strip can be supported against the lower mounting strip to press the die mounting plate onto the lower mold frame plate.

[0017] Thus, the corresponding mounting arrangement of the die cavity structure is in the lower mounting groove of the lower die holder plate.

[0018] This ensures the accuracy of installation and spacing adjustments.

[0019] As an optimization, the upper combined mold frame includes an upper mold frame plate. A longitudinally penetrating lower mounting groove is provided on the lower surface of the upper mold frame plate, and the punch positioning plate is correspondingly arranged in the upper mounting groove. The upper ends of both sides of the punch positioning plate protrude outward to form upper mounting strips, and the two outer sides of the upper mounting strips are respectively attached to and supported on the side wall of the upper mounting groove. An upper pressure strip plate is provided on the upper mold frame plate and corresponding to the upper mounting strip. The upper pressure strip plates are respectively connected to the upper mold frame plate by screws, and the upper pressure strip plates can be attached to and supported on the upper mounting strips to press the punch positioning plate onto the upper mold frame plate.

[0020] Thus, the corresponding mounting arrangement of the punch structure is in the upper mounting groove of the upper die holder plate.

[0021] This ensures the accuracy of installation and spacing adjustments.

[0022] As an optimization, longitudinally arranged upper combined mold frame reinforcing blocks are also provided on both sides of the upper mold frame plate. The inner side of the upper combined mold frame reinforcing block is provided with a mounting groove, and the corresponding upper mold frame plates on both sides are inserted into the mounting groove. The upper combined mold frame reinforcing blocks are connected and fixed to the upper mold frame plate by connecting screws.

[0023] In this way, by designing a combination of mold frame reinforcing blocks, the rigidity of the entire device can be improved.

[0024] As an optimization, the mold handle structure includes a first mold handle that is installed on the upper mold frame plate and arranged vertically; a mold handle block arranged vertically is also provided above the upper mold frame plate, and each end of the mold handle block is connected to a vertically arranged connecting rod, the lower end of which is connected to both ends of the upper mold frame plate.

[0025] In this way, in addition to the first die shank, a die shank block is also provided. The die shank block is inserted into the punch press lifting head, so that the upper combined die frame is more firmly fixed on the punch press.

[0026] As an optimization, the vertical guide section structure includes a pair of guide rods arranged on the die mounting plate, and a guide sleeve is provided on the punch mounting plate for each corresponding guide rod.

[0027] In this way, the vertical guide section uses a combination of guide rods and guide sleeves, which has the advantage of a simpler and more reasonable structural design.

[0028] Furthermore, the punch structure includes a pad plate installed below the punch mounting plate, on which the punch is mounted; a pressure plate is also provided, with a clearance opening on the pressure plate for the punch to pass through; and connecting screws are vertically slidable at both ends of the pad plate, with the lower end of the connecting screw corresponding to a connecting hole in the pressure plate; a helical spring is sleeved on the outside of the connecting screw, giving the pressure plate a downward movement tendency.

[0029] In this way, during the stamping process, the pressure plate can first press the ruler body, and then the punch can complete the stamping, which can improve the accuracy and reliability of stamping.

[0030] In summary, the above-mentioned structure has the advantages of simpler and more reasonable structural design, improved processing efficiency, reduced equipment investment, better accuracy of opening on the ruler and opening position, and reduced equipment investment costs.
